During the working process of the three-side bag sealing machine, the size of the film feeding is different, the size of the material feeding is more than 5mm shorter than the pre-adjusted size, and the situation of no film feeding occurs intermittently during the working process.

Treatment methods:

1. Poor sensitivity adjustment or wrong polarity selection of photoelectric eye.

2, the photoelectric switch on the ground leakage or short circuit between the ends, should be replaced.

3. If the feeding speed is lower than the feeding speed, it is necessary to relax the film laminating, check the performance of the feeding part and troubleshoot.

4. The stepping motor torque of bag-making machine decreases, and the bag-making size is inaccurate.

Solutions:

The stepping driver is faulty, or the connection between the rubber roller and the stepping motor is blocked. Check and repair the stepping driver in time, connect the roller with the stepping motor.
