2. بناء, الميزات الفنية, البيانات الفنية الرئيسية

بناء:

يشمل الهيكل الرئيسي للجهاز: إطار, سلسلة مقطع فيلم, آلية انتقال, أعلى فيلم تثبيت الأسطوان, أسطوانة الفيلم السفلي, أسطوانة ماطفة الفيلم السفلي, تشكيل غرفة, منطقة التحميل, غرفة التغليف فراغ, سكين تقاطع, سكين قطع طولية, نظام هوائي, نظام فراغ, نظام التحكم الكهربائي, إلخ.

الميزات الفنية:

نظام النقل
يتحرك الفيلم السفلي للأمام تحت تقطيع سلسلة مقطع الفيلم مجهزة بمقاطع فيلم. تدرك سلسلة مقطع الفيلم حركة خطوة دقيقة تحت محرك تحويل التردد (أو المؤازرة) نظام النقل. الآلة تتبنى العلامة التجارية الشهيرة المحركات الشهيرة, وحدات تحكم قابلة للبرمجة (بلك) والتحكم التلقائي في الشاشة, وهي دقيقة وموثوقة في السيطرة وبسيطة للعمل.
تشكيل غرفة
تتكون غرفة التشكيل من غرف العمل العلوية والسفلية وتشكيل القوالب المقابلة للمنتجات الجديدة التي يتم تعبئتها. يتم تثبيت غرفة العمل العلوية على الإطار عن طريق البراغي من خلال منشورات التوجيه. تتحرك غرفة العمل العلوية لأعلى ولأسفل بالمثل تحت محرك الأسطوانة. تم تجهيز غرفة العمل العلوية بألواح التدفئة ولوحات العزل الحرارية. يتم التحكم في درجة حرارة التدفئة من خلال وحدة تحكم درجة الحرارة (أو وحدة التحكم في درجة الحرارة) و thermocouple. يمكن للمستخدم تعيين درجة حرارة التدفئة بسهولة على لوحة تحكم درجة الحرارة. عملية العمل هي أن غرفة العمل السفلية ترتفع أولاً إلى وضعها العلوي. بعد أن يتم إغلاق غرف العمل العلوية والسفلية تمامًا بواسطة وسادة ختم السيليكون, تقوم لوحة التسخين بتسخين الفيلم السفلي. ثم يتم إجلاء غرفة العمل السفلية لتوليد قوة شد في الفيلم السفلي, غرق في القالب التكوين ليصبح شكلًا هندسيًا يتوافق مع المنتج الذي سيتم تعبئته. تختلف درجة حرارة التكوين اعتمادًا على الجودة, مادة, سماكة, قسوة الفيلم الممتد المستخدم. يتم تحديد درجة حرارة التكوين المعقولة عن طريق الاختبار, عموما حوالي 90 درجة مئوية. الحد الأقصى لعمق الرسم لهذا الجهاز هو حول 80 مم. يتم ضبط عمق الرسم المطلوب بواسطة الخطوط في الغرفة السفلية أثناء التشغيل. وفقا لمتطلبات المستخدم, يمكن تخصيص قالب التكوين.
منطقة التحميل
يتم وضع المنتجات المراد تعبئتها يدويًا في تجويف القالب السفلي في منطقة التحميل. تحتوي منطقة التحميل على شركة طيران مادية, الذي يتم اختياره واستخدامه وفقًا لقالب التكوين المقابل, وهو أمر بسيط للغاية لإدخاله واستخدامه.
غرفة التغليف فراغ
عندما يدخل المنتج المعبأ إلى غرفة التغليف التي يقودها الفيلم السفلي, يتم تغطية الفيلم العلوي تلقائيًا, ويتم الانتهاء.

تتكون غرفة التغليف فراغ من غرف العمل العلوية والسفلية. تم تجهيز غرفة العمل العلوية بألواح التدفئة والأكياس الهوائية. ضغط التضخم في الوسادة الهوائية بين 0.05 و 0.2mpa, ويجب ألا يتجاوز الحد الأقصى 0.25mpa, وإلا فإن الوسادة الهوائية ولوحة التدفئة الكهربائية ستضر. عملية عمل غرفة الفراغ: عندما تدخل المادة المعبأة إلى غرفة العمل, ترتفع غرفة العمل السفلية إلى موضع الحد الأعلى تحت محرك الأسطوانة ويتم إغلاقها في واحدة مع الغرفة العلوية. ثم يتم استخراج الهواء في تجويف التغليف بواسطة نظام الفراغ, ويتم قيادة لوحة التسخين لأسفل بسبب تضخم الوسادة الهوائية لتسخينها وختم منطقة الختم. تكون درجة حرارة الختم بشكل عام حوالي 130 درجة مئوية. من أجل منع فيلم التعبئة والتغليف من التمسك بلوحة التدفئة, سطح تسخين لوحة التسخين مطلية بطبقة بلاستيكية غير لاصقة. إذا كانت درجة حرارة لوحة التسخين مرتفعة للغاية أو أن العملية غير السليمة الأخرى تتسبب, إلخ., it should be checked regularly and carefully wiped off with a soft object or soft cotton cloth at a certain temperature (about 100°C). Sharp objects are strictly prohibited to prevent damage to the non-stick coating.
Cross-Cutting Knife
The machine adopts punch-cutting for transverse cutting of the packaging film, and is generally equipped with 4 cross-cutting knives. The cross-cutting knife consists of upper and lower knives. The upper knife is a toothed knife die, and the lower knife is a serrated blade, which coincides with the upper knife die. The lower knife is driven upward by a cylinder, and the lateral clearance between the upper and lower knives should be reasonable (see the instructions later for adjustment). The four cross-cutting knives are controlled by pneumatic valves, بلك, and touch screen. If there are several rows of products in the left and right direction in one pitch or in one working chamber, then select several rows of knives on the touch screen. على سبيل المثال, if it is one row of products, select “one row of knives” on the touch screen, and if it is two rows of products, select “two rows of knives”, and if it is three rows of products, select “three rows of knives”……Then the “PLC” will automatically select the required cross-cutting knives among the 4 cross-cutting knives.
Longitudinal Cutting Knife
The machine’s longitudinal cutting knife adopts a rotary cutting knife. The longitudinal cutting knife also consists of upper and lower knives. The upper knife is a high-speed rotating circular blade, and the lower knife is made of aluminum alloy. The lateral clearance between the upper and lower knives should be reasonable to prevent damage to the blade and affect the cutting effect. The number of longitudinal cutting knives is determined by the mold used. There are several sealing lines, and several knives are used.
Vacuum System
The machine’s vacuum system consists of a vacuum pump, pneumatic vacuum valve, vacuum pipeline, and joints. The machine uses a German original imported “vacuum packaging machine special pump”. وفقا لمتطلبات المستخدم, a vacuum pump with a pumping rate of 100m3/h—300m3/h can be equipped. In order to improve the intake cleanliness of the vacuum pump and extend the service life of the vacuum pump, the machine is equipped with an intake filter, which needs to be cleaned regularly to prevent it from blocking and reducing the pumping rate of the vacuum pump.
Pneumatic System
Most of the actions of the machine’s forming lower chamber, vacuum lower chamber, cross-cutting lower knife, high-pressure sealing, top film braking, and date printing are realized by solenoid valves, الأسطوانات, and compressed air systems. Therefore, users are required to have a compressed air station or a spare air compressor with a supply volume of not less than 0.5m3/min. In order to ensure the long-term safe and normal operation of the equipment, the user’s compressed air pipeline system must be equipped with a matching oil-water separator. Note that the oil-water separator equipped by the user and the oil-water separator installed on the machine must drain water every shift. Pay more attention to this point in humid working environments, and increase the number of water drains if necessary.
Electrical System
The machine uses 50HZ, 380V three-phase five-wire power supply, three-phase wire one neutral wire one ground wire. When the phase wire neutral wire is connected to the machine, it should correspond one-to-one. The neutral wire and the phase wire cannot be connected incorrectly. After careful verification, the machine can be powered on, otherwise the 220V electrical appliances of the machine will be burned out by high voltage! Pay attention to this point, and then verify the forward and reverse rotation of the motor. أخيراً, after verifying that there is no error, the machine can be powered on and work normally. The main components used and the power supply mode are: The main controller PLC requires a DC 24V power supply, and the 24V DC power is supplied by the switching power supply in the electrical box. The stepping control system adopts foreign imported servo motors, which are precise, مستقر, and easy to operate.

The human-machine interface adopts foreign famous brand touch screen, 24V DC power supply. Pay attention not to reverse the “+” and “-” terminals of the 24V DC power input end during maintenance, otherwise it may cause damage to the touch screen. Adjustment of parameters on the touch screen: The vacuuming time can be adjusted arbitrarily according to needs, generally 3-15 seconds. The preheating time is generally set to 3-6 seconds. The stretching time is 2 seconds. The venting time is generally not less than 1.0 second. When adjusting the touch screen, do not use too much force. Just “touch” it to prevent damage to the screen and cause major losses (the touch screen is expensive electronic equipment).

Heating temperature control part: Electric heating plates are installed in the forming chamber and vacuum chamber respectively, 220V AC single-phase power supply, and built-in thermocouples. The temperature controller is “OMRON” temperature control module, and the temperature display and control are simple, convenient, and intuitive on the touch screen.

There is a safety switch under the cross-cutting knife cover of the machine. The power supply is low-voltage 24V DC. When the knife cover is not installed or the installation position is incorrect, it cannot move, and the machine cannot work, so as to play a safety protection role, which can prevent accidentally putting hands under the knife and avoid personal injury accidents. Therefore, users must not arbitrarily change this function or accidentally introduce high-voltage electricity into the electrical box through the switch, which will damage electronic equipment using 24V power and cause damage to the machine.

III. أجزاء العمل, يستخدم, Replacement and Adjustment of Wearing Parts

1. استبدال القوالب في تشكيل غرفة وغرفة فراغ

Lower the lower chamber of the working chamber (forming chamber and vacuum chamber) to the lower limit position.
Remove the mold and mold pad from the lower chamber by hand.
Place the required mold and pad corresponding to the required drawing depth.

ملحوظة: There are special pads at the suction hole positions in the lower chamber, do not use them wrong to prevent the suction holes from being blocked, causing failure to stretch or incomplete stretching!

2. Replacement of Electric Heating Plate and Thermocouple

Adjust the air source pressure to 0.2MP, and manually raise the vacuum chamber to the highest point (open the rear hood to find the pneumatic solenoid valve of the vacuum chamber, which has a red manual button), and then turn off the air source.
Unscrew the bolts that fix the forming chamber/vacuum chamber to the frame.
Remove the 220V electric heating plate power cord, thermocouple wiring and air circuit pipeline.
Remove and turn over the upper forming chamber. Just open the top cover of the vacuum chamber.
Carefully and carefully replace the damaged thermocouple or electric heating plate.
Connect the wires and fix the working chamber. أخيراً, reset the vacuum upper chamber and install the hood.

3. Adjustment of Cross-Cutting Knife and Replacement of Lower Blade

If serious burrs occur in the cross-cut, there are two reasons: one is that the lower blade is damaged, such as chipped or rolled edges; the other is that the lateral loosening of the upper and lower knives results in excessive clearance. If the cutting edge is damaged, it should be removed and re-sharpened, or replaced with a new knife. If the lower knife is loose, the lateral clearance between the lower knife and the upper film needs to be readjusted. Visually, it is about 0.05 مم (the cylinder is manually raised to the top at a low pressure of about 0.2Mpa, and the blade can be visually inspected after inserting into the upper knife). أخيراً, tighten the fixing bolts, and test by moving the air cylinder manually at a pressure of no more than 0.05Mpa to ensure that there are no errors before putting it into use.
The cut is not in the center of the seal.
This phenomenon is mostly caused by the offset caused by the loosening of the cross-cutting knife fixing nut. You need to re-center and adjust the corresponding packaging seal, and then tighten the fixing nut.

4. تعديل سكين القطع الطولية

If the longitudinal cutting knife cannot cut or burrs occur, the reasons are: (1) The blade edge is passivated or the edge is rolled and chipped, and it needs to be removed for repair or replacement; (2) The clearance between the upper and lower knives is too large, the fixing screw of the blade holder should be loosened, adjust the clearance to about 0.3-0.1 مم, and then tighten the fixing screw.

5. تعديل سلسلة مقطع الأفلام واستبدال مقاطع الأفلام

After the machine has been used for a period of time, the chain may become loose, causing the film clip opening to be too small to clamp the film or the film clip to fall off, and it needs to be adjusted and replaced in time.

Adjustment of tension
There are chain tensioning bolts on the right side of the machine. Use a wrench to evenly turn the bolts on both sides clockwise for a few turns to tension the chain, but do not tighten it too much to prevent damage to the chain and related parts. If this adjustment cannot meet the tension requirements, you can remove a chain link from the chain joint.
Replacement of film clips
If there are damaged film clips, they should be removed and new ones installed in time. If the number is small, you can directly replace them with pointed pliers without disassembling the chain on the machine.

6. Installation and Adjustment of Bottom Film Roll and Top Film Roll

The top film roll and bottom film roll are manually installed on the bottom film roll shaft and top film roll shaft respectively, and are clamped between the two baffles at the lower end of the film pressing link. The installation direction of the top film is generally counterclockwise to the winding direction of the film roll, and the bottom film is clockwise (see attached picture). When you start working with a new bundle of film, pay attention to whether the film runs off and causes the bottom film to be clamped unevenly on both sides of the film clip chain or one side is not clamped, causing the work to be unable to proceed or the top film completely covers the lower vacuum chamber, causing no vacuum. At this time, the front and rear positions of the film roll need to be adjusted. The method is: on the support beam of the link above the top film, there is a fine adjustment handle at the far right of the frame, which is used to fine-tune the film’s deflection. When the handle is swung clockwise, the film roll moves towards the rear of the machine, and vice versa, it moves towards the front of the machine. Slowly adjust until the working requirements are met.

7. Sealing Strip (Sealing Silicone Pad)

If you find that the sealing is not good, or the vacuum degree is not good for unknown reasons, or the forming is not good, you should check whether the sealing strip is damaged or aging, or the joint is not tight, and the gap is too large. If it is damaged, it needs to be replaced in time. If the joint is too large, it should be reinstalled, or the joint should be bonded and sealed with high-quality silicone.

8. نظام تحديد المواقع الكهروضوئية واستخدامه وتعديله

The photoelectric positioning system consists of a photoelectric switch, a pressure regulating valve, a pneumatic solenoid valve, and a brake, and is controlled by a “PLC”. When using color-printed cover film, it is used to position the color film so that it accurately corresponds to the bottom film and does not run off. Otherwise, the pattern will be offset on the packaging, which will not meet the requirements for use.

Color film use principle: The bottom film moves forward accurately in a stepping manner under system control. The corresponding color cover film, without being controlled, gradually shifts away from the packaging center after a period of time due to its own stretching and the accuracy of printing, making it unusable. Therefore, the movement of the color film must be controlled. If a color mark is printed on the center line of every two adjacent working positions on the color film (this machine uses a 14×6mm black color mark), when the photoelectric switch detects this color mark, the braking system brakes and positions the cover film, and is controlled by the “PLC” to synchronize with the bottom film movement, so that the packaging requirements can be met. The machine has a pitch of 394mm, and the color mark printing distance is between 392-393.5mm, printed on the sealing strip in the middle of each adjacent pitch. The attached picture below shows the color mark printing positions for 9 packages with a pitch length of 394 مم.

[Image: Color mark printing positions]

Photoelectric Positioning System Use Adjustment Steps:

After starting the machine, open the electrical box door, find the solenoid valve and pressure regulating valve combination that controls the brake, and press the red manual button on the solenoid valve to check whether the system air circuit is connected properly and whether the brake action is sensitive. At the same time, adjust the pressure reducing valve to a working air pressure of about 0.25Mpa.
Install the color film roll, and route the color film around the guide rollers on the electrical box to the front of the working chamber. Install the bottom film, and the machine starts to work. When the formed bottom film steps to 2 pitches before the vacuum working chamber, turn the “Work/Stop” switch to the stop position to allow the machine to stop running automatically.
Pull out the color film for at least one more pitch length, and cover it flat on the bottom film, and align the “sealing strip” printed with the color mark with the sealing position on the front pitch line of the bottom film, and then fix the front end of the color film and the bottom film together with tape.
Turn the “Work/Stop” switch to the “Work” position to allow the cover film and bottom film to naturally enter the vacuum chamber together, and then turn the switch to the “Stop” position to stop the machine from running. Then move the film roll by hand to make the pulled film in a natural tension state.
Touch the “Color Film Selection” button on the control screen, the indicator light is on, and then adjust the position of the photoelectric switch to make the focal point of the emitted light illuminate about 5mm above the center of the color film “color mark”, and make the end face of the switch emitting light about 10mm away from the color film. For the specific use method, please refer to the attached color mark photoelectric switch manual.
After the above adjustments are completed, you can enter experimental operation. During the working process, observe whether the brake pad acts as required, and whether the color mark of the packaged finished product is in the center position of the seal. When starting to work, the color mark may not be in the center position of the seal, or it may be left or right. You must readjust the upper and lower positions of the photoelectric switch to correct the deviation. The method is: if the color mark position is biased to the left, appropriately adjust the switch position upwards by a few millimeters, and vice versa, lower it by a few millimeters until the packaging requirements are met. After the adjustment is completed, fix the switch position, and then you can enter normal work. During the working process, do not allow the color film to vibrate, and sticking it to the light barrier can solve this problem.

ملحوظة: During the working process, pay attention not to touch the color film to prevent the photoelectric switch from malfunctioning, which may lead to the failure of the color film being pulled off. When you don’t use color film and switch to light film, adjust the touch screen to the “Light Film Selection” state. (ملحوظة: The focal point walking route of the photoelectric switch, that is, the color of the sealing area must be a single color.

CB Series Thermoforming Vacuum Packaging Machine Basic Operation Steps

First check the lubrication condition of each moving part of the machine (pay attention to adding oil and lubricating regularly, and add oil once every 5 days as needed), then turn on the power, and turn on the air source to check whether the air pressure reaches the rated pressure (0.6MPA). If the product needs to be inflated, check whether the inflation air source is connected properly and whether the pressure meets the requirements.
Start the vacuum pump on the touch screen, and open “Status Monitoring” to check whether the “Safety Switch” and “Emergency Stop” switches are in a normal state.
Turn the “Work/Stop” switch to the “Work” position to test run to check whether each working part is normal.
Turn off the “Air Source” and “Power Supply” again, and select the appropriate mold and mold depth, bracket, and tool (longitudinal knife) according to product requirements.
Install the upper film (counterclockwise) and the bottom film (clockwise), turn on the power and air source and cooling water (there is water flowing out), and use the “jog” switch to move the bottom film into the “forming chamber”.
When the temperature (forming temperature, vacuum heat sealing temperature) rises to the required value, select the cross-cutting knife corresponding to the product and the appropriate vacuum time, and start the vacuum pump (vacuum heat sealing 110℃—150℃, forming: 70℃—110℃).
After the above work is done, you can turn the “Work/Stop” switch to the “Work” position for trial operation, and check the bias and correction of the bottom film in time.
When the formed bottom film steps to the
