The method to repair scorch wrinkles appearing on the packaging machine's sealing is to increase the speed.

After comparing similar automation products, the Delta Industrial Automation product platform was selected as the full series control system for this packaging machine. This control system solution is based on the integration of DELTA AE series human-machine interface, EH series PLC, ASD-AB servo system, and other products. The roller can sensitively structure the control scheme through the data communication function of these products. Compared to traditional PLC pulse motion control schemes, the ASD-AB servo system offers higher reliability and more precise control.
The PR control single-axis positioning control method is a function of the Delta AB series servo system. The positioning point and servo speed of the roller motor rotation are determined by the internal position register and speed register respectively. The values in position registers P1-15 and P1-16 assign the motor displacement distance. The value in speed register P2-36 assigns the motor displacement speed for this segment, and the motor speed needs to be set. The PR mode DI GTRG command trigger signal is given on the rising edge, and the servo motor moves according to the register plan.

It can be used not only for packaging materials without trademarks but also for high-speed packaging using roll materials pre-printed with trademark images. In packaging production, due to errors between the printed positioning color marks on the packaging materials, stretching of the packaging materials, and mechanical transmission factors, the predetermined sealing and cutting positions on the packaging materials may deviate from the correct position, causing errors. To eliminate errors and achieve correct sealing and cutting, the packaging design must consider automatic positioning issues. Most solutions to this problem are based on the continuous photoelectric automatic positioning system design according to the positioning marks on the packaging materials. The continuous photoelectric positioning system is divided into forward-backward type, braking type, and dual-drive system synchronization type according to the error compensation operation method.

If the temperature is too high, the speed is too slow, or the outer layer of the film has poor heat resistance, sealing will show scorch wrinkles. The repair method is to increase the speed, lower the temperature, and replace the film material. If the knife holder is too high or too low, the packaging speed is too fast, or the pusher and cutter are not synchronized, the cutter will cut into the product. The repair method is to reduce the packaging speed and adjust the height of the end sealing component so that the sealing knife center is at the middle height of the product. If the film color mark is too light, the film drive slips, or the color mark tracking is not enabled, blocking position deviation from the color mark will occur. The repair method is to refer to the packaging machine manual and adjust its sensitivity; in the human-machine interface, switch the tracking method to "tracking cut." If the solid-state circuit breaker burns out, the temperature controller is damaged, or the thermocouple is damaged, the temperature controller cannot control the temperature. The repair method is to replace the thermocouple, replace the temperature controller, and replace the heating element. If the speed is too fast, the inner layer of the film has poor heat sealing, or the temperature is too low, sealing will leak or be weak. The repair method is to slow down the speed, increase the temperature, and replace the film material. If the air pressure is incorrect, the cylinder rocker is loose, the heating temperature is low, or the heat sealing roller and drive roller are not parallel, heat sealing defects will occur. The repair method is to adjust the parallelism, temperature, and air pressure to tighten them.

It should also be noted that before powering on, the induction aviation plug must be inserted and the screws locked; metal covers and metal containers must not be used, nor should the machine be placed on a metal table when pressing the start button, as this will damage the machine. During operation, the surface of the induction head should be frequently touched to check for overheating. If any difficulty is found, heating should be stopped and resumed after cooling. There is high voltage inside the pillow packaging machine body, and the base plate is electrified. Repairs must be done with caution to avoid personal injury risks.
