AI Technical Summary
In existing coating machines, the film roll is adjusted by using a ruler and a handwheel screw. The adjustment response is slow, which causes the coating layer on the film roll to shift, affecting the yield.
The system employs a sliding guide rail and moving plate structure with intervals, combined with a correction drive mechanism and photoelectric sensor to achieve automatic correction and adjustment of the film roll position. The film roll is guided to move by a roller mechanism, and the position of the film roll is adjusted by a telescopic motor and a drive motor to ensure the accuracy of the coating position.
This technology enables real-time correction of the film roll during the traction process, improves the adjustment response speed of the coating machine, reduces coating layer offset, and increases the yield rate.
