Electric Doypack packaging machine Customized granule powder liquid packaging solution

Doypack premade pouch packing machine

The control system of a doypack packaging machine operates based on the following principles:

I. Core Control Architecture

PLC Main Control System:

Utilizes a Siemens/Mitsubishi PLC as the primary controller to coordinate bag taking, opening, filling, sealing, and other actions through preset programs.
Supports multi-axis linkage control for precise movements, such as servo motor-driven heat sealing plate accuracy up to ±0.1mm.
Servo Drive Module:

Enables accurate positioning of the heat sealing plate using a worm gear mechanism to prevent deviations seen in traditional cylinder single-sided feeding.
Synchronizes the bag feeding mechanism and metering device to ensure timing alignment of material filling and bag delivery.
II. Sensor Coordination Mechanism

Real-time Monitoring System:

Photoelectric sensors detect bag position status, triggering warning shutdown in case of missing bags to minimize idle loss.
Weight sensors monitor filling volume, automatically rejecting substandard products during abnormalities.
Closed-loop Feedback Adjustment:

Temperature sensors dynamically adjust heat sealing knife parameters (150-200℃), issuing alarms for poor sealing.
Position sensors ensure the bag opening mechanism's airflow injection angle matches the bag opening.
III. Human-Machine Interaction Interface

Touch Screen:

Displays operational parameters (e.g., speed, temperature, output) and provides real-time fault code prompts.
Programmable Interface:

Enables quick switching of packaging specifications, with production parameter adjustment time ≤3 minutes.
IV. Safety Protection Function

Emergency Stop Button:

Directly cuts off power supply, featuring mechanical and electrical dual circuit protection.
Automatic Interlocking Shutdown Function:

Halts the process immediately upon detecting bag jams or heat sealing abnormalities to ensure operational safety.

• Ease of operation: Featuring an intuitive interface and automated control system, these machines are user-friendly, facilitating easy operation and maintenance.
• Quality assurance: Dependable sealing technology and detection systems uphold the quality and integrity of the packaged items.

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:

• Product Feeding and Metering: Initially, the packaging machine's feeding system processes the products, which can vary from powder to granules to liquids. Typically, a metering system is integrated to ensure precise product quantities in each bag.
• Bag Conveying and Formation: Premade bags are extracted from the roll material and, following a series of conveying mechanisms, are opened and directed to the filling zone.
• Product Filling: The product is dispensed into the bag based on predetermined parameters. For liquid products, a pump system or similar liquid filling equipment is utilized to guarantee accurate filling.
• Sealing: Post-filling, the bag is transported to the sealing section. Depending on the product and specifications, heat sealing, cold sealing, or other sealing methods are employed to seal the bag mouth, ensuring product freshness and a secure seal.
• Printing and Inspection: Subsequent to sealing, the bag may undergo a printing process to add product details or brand logos. Some packaging machines also feature detection systems to verify sealing quality and product integrity.
• Discharge and Stacking: Ultimately, the completed bags are discharged in the designated area, where they can be stacked or processed further using conveyor belts or alternative methods.

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