The photoelectric detection assembly is used for detecting whether there is a film in a specified area. When the photoelectric detection assembly cannot detect the presence of the film, the control module controls the transfer device and the mechanical arm to realize the operation of grabbing the film in the film stacking area and releasing the film in the film releasing area. The first proximity detection assembly and the second proximity detection assembly are both used for detecting whether the transfer device is moved to the position. However, it is only used for single-layer feeding device, occupies a large space, is arranged directly above the conveying belt, and can only be applied to single-layer film cutting machine and space-unlimited working conditions.

Then the first grabbing clamp 420 is lifted with the mobile device, and after being lifted to zero, the cylinder of the swing arm pressing assembly 10 acts to drive the swing arm to open, at this time, the first grabbing clamp 420 is driven by the first lateral drive motor 210 to start horizontal lateral movement to the conveying belt of the cutting machine. When the lateral movement reaches the specified position, the diffuse reflection photoelectricity detects a signal, indicating that the film grabbing is completed, the cylinder of the swing arm pressing assembly 10 acts to drive the swing arm to close and press the film to prevent the film from falling off, and then the first grabbing clamp 420 acts to release the film; after the lifting shaft 400 is lifted to the position each time, the locking rack 540 is locked under the action of the cylinder 550 to prevent abnormal falling; the double-station can be independently operated at the same time to perform film coating on the double-station.
