Similarly, the housing 17 is attached to the outer wall of the base on the side thereof so as to protect the air pressure regulator 61, the air dryer 62, and the solenoid control valve block 63.

Preferably, the rear side of the conveying belt 31 is provided with a collecting box 314 to facilitate the collection of the die-cut film.

When the film sheets which are produced, formed and stacked together need to be subjected to die cutting, the film sheets are placed in the material placing area 24 and are fixed by pressing the material pressing plate 25 downwards, then the paging belt 21 drives the film sheets positioned at the lowermost layer to move backwards, and only the film sheets positioned at the lowermost layer are allowed to move backwards continuously under the blocking of the baffle plate 22 and the flatness limiting plate 23, at the moment, the controller 55 controls the piston rod of the double-shaft cylinder 26 to extend out by a corresponding length, so that the pressure of the material pressing plate 25 on the film sheets of the material placing area 24 is ensured, the paged film sheets move onto the conveying belt 31 and then move backwards along with the conveying belt 31, the film sheet detecting unit detects the rear edge of the film sheets, the controller 55 can calculate the time point when the film sheets move to the die cutting station according to the detection signal, the rotating speed of the conveying belt 31 and the fixed length from the detection point to the die cutting station, the controller 55 can control the die, therefore, accurate die cutting is carried out when the film moves to the die cutting station, and the film after die cutting can continuously move backwards along with the conveying belt 31 and finally fall into the material receiving box 314.

In light of the foregoing description of the preferred embodiment of the present invention, many modifications and variations will be apparent to those skilled in the art without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
