Reasons and solutions for the height loss of the film wrapping machine

When the height of the film wrapper is still higher than the height of the packaged object, it is out of control. The main reasons for this phenomenon are: the photoelectric switch is out of order, the light around the switch is too strong, and the photoelectric setting is improper.
For the above reasons, it can be solved by replacing the photoelectric switch, adding a hood to the photoelectric switch, and resetting the photoelectric detachment time.
