(1) Check whether the main motor steering is correct and adjust to the correct direction indicated by the arrow.

(2) Whether the stepper motor driver shows fault, turn off the main power and re-energizing can be restored to normal.

2, the length of the film feeding size is different during the working process, the feeding size is more than 5mm shorter than the preset size, and the film is not sent once intermittently during the working process.

Treatment methods:

(1) photoelectric eye sensitivity adjustment is not good or polarity selection is not correct.

(2) The photoelectric switch should be replaced by ground leakage or short circuit between the ends.

(3) The discharge speed is lower than the feed speed, it is necessary to relax the film laminate, check the performance of the discharge part, and troubleshoot.

3, stepper motor torque decreased significantly, bag size is not accurate.

Solution: The stepper driver has a fault, or the rubber roller and the stepper motor connection part has a blocking phenomenon. Check and repair the stepper drive in time, connect the rubber roller and the stepper motor.

4, bag time electrical tracking is not accurate.

Treatment methods:

(1) The adjustment method and working state of the photoelectric eye are not correct, and the correct adjustment is required according to the instructions.

(2) The preset film feeding length (when adjusting the blank bag) and the actual bag size error is too large, should be reset the length of the line or adjust the pressure, adjust the device.

(3) The film resistance is too large or the quality of the previous process products is poor, should be checked and replaced. 5. Low discharge speed or abnormal operation.

Treatment methods:

(1) The eye position switch is in poor contact or the CAM Angle is not good, should be adjusted or replaced.

(2) The circuit board thyristor or rectifier tube breakdown should be repaired or replaced. Mechanical equipment and its processing objects, here we specifically refer to plastic film, have a mutual adaptation characteristics, that is, a mechanical equipment can only process a certain range of plastic film, we understand the nature of plastic film on the basis of the three elements of bag making, namely: Pressure, temperature, and pressing time, when making bags (on the premise of ensuring pressing strength, relatively speaking), the pressing pressure should be large, the pressing temperature should be low, and the pressing time should be long, and the pressing sealing of the composite bag after such treatment is beautiful, beautiful, and straight.
