WZ250 Doypack Packaging Machine PE Composite Film Material Self-supporting Bag Packaging

Doypack premade pouch packing machine

Working principle of the control system of doypack packaging machine
‌I. Core control architecture‌
‌PLC main control system‌
Adopt Siemens/Mitsubishi and other brand PLC as the main controller, coordinate the timing of bag taking, bag opening, filling, sealing and other actions through preset programs
Support multi-axis linkage control, such as servo motor driven heat sealing plate movement accuracy can reach ±0.1mm
‌Servo drive module‌
Accurate positioning of the heat sealing plate is achieved through the worm gear mechanism to avoid the deviation problem of single-sided feeding of traditional cylinders
Synchronize the bag feeding mechanism and metering device to ensure the timing matching of material filling and bag body delivery

‌II. Sensor coordination mechanism‌
‌Real-time monitoring system‌
Photoelectric sensor detects the bag position status, triggers warning shutdown when there is no bag, reduces Idle loss
Weight sensor monitors filling volume, automatically rejects unqualified products when abnormal
Closed-loop feedback adjustment
Temperature sensor dynamically adjusts heat sealing knife working parameters (150-200℃), automatically alarms when sealing is poor
Position sensor ensures that the airflow injection angle of the bag opening mechanism matches the bag opening

III. Human-machine interaction interface
Touch screen displays operating parameters (such as speed, temperature, output), supports real-time prompts of fault codes
Programmable interface allows fast switching of packaging specifications, and the adjustment time of production change parameters is ≤3 minutes

IV. Safety protection function
Emergency stop button directly cuts off the power supply, mechanical and electrical dual circuit protection
Automatic interlocking shutdown function immediately terminates the process when bag jam or heat sealing abnormality is detected

Product Advantages

The doypack premade pouch packing machine has many advantages that make it the preferred packaging solution in many industries:

• Versatility: It can adapt to different types of bag types (three-dimensional bags, flat bags, straw bags, etc.) and different kinds of products (food, cosmetics, pharmaceuticals, etc.).
• Efficiency: Automated operation and high-speed packaging capabilities improve production efficiency, saving time and labor costs.
• Accuracy: The precise metering of the filling system ensures that the amount of product in each bag is accurate.
• Flexibility: Adjustable parameters and configurations make it suitable for a variety of packaging needs, such as bags of different sizes, different packaging materials, etc.
• Hygiene: The design meets hygiene standards and is suitable for the food and pharmaceutical industries to ensure the hygiene and safety of products.
• Space saving: Compared with traditional packaging equipment, Doypack packaging machines usually have a smaller footprint, saving production space.
• Easy to operate: Most machines are equipped with an intuitive interface and automated control system, which is easy to operate and maintain.
• Quality assurance: Reliable sealing technology and detection systems ensure the quality and integrity of product packaging.

Doypack premade pouch packing machine is an automated equipment used to pack various products. The following is a brief description of the working principle of doypack premade pouch packing machine:

• Feeding and metering: First, the products are fed into the feeding system of the packaging machine. These products can be in the form of powder, granules, liquids, etc. The packaging machine is usually equipped with a metering system to ensure that the amount of product in each bag is accurate.
• Bag conveying and forming: The premade bags are taken out from the roll material, and after a series of conveying systems, the bags are opened and conveyed to the filling area.
• Product filling: The product is filled into the bag according to the preset parameters. For liquid products, a pump system or other liquid filling equipment is usually used to ensure accurate filling.
• Sealing: After filling, the bag is conveyed to the sealing area. Depending on the product and requirements, heat sealing, cold sealing or other sealing technologies can be used to seal the bag mouth to ensure the sealing and freshness of the product.
• Printing and detection: After sealing, the bag may pass through a printing system to print product information or brand logo. At the same time, some packaging machines are also equipped with detection systems to check the sealing quality and product integrity.
• Discharge and stacking: Finally, the finished bags are discharged to the discharge area, where they can be stacked or packaged by conveyor belts or other means.

This is a basic workflow, and the specific operations and functions vary depending on different doypack premade pouch packing machine models and production needs.
