[0023] A support plate 8 is fixedly installed at the bottom end of the fixed frame 1, and a tape collection wheel 9 is rotatably installed on the front side of the support plate 8 near the bottom end. The front surface of the support plate 8 is rotatably connected to two rollers 4. The tape wheel 6 passes through the outer sides of the rollers 4 on the surfaces of the fixed frame 1 and the sliding plate 3 in turn, and extends to the position of the tape collection wheel 9 through the rollers 4 on the surface of the support plate 8.

[0024] A movable frame 7 is provided at the top of the fixed frame 1 , a film is provided at the bottom of the movable frame 7 , the surface of the tape wheel 6 is in contact with the bottom surface of the film, and a suction cup mechanism is connected to the top of the movable frame 7 .

[0025] When the sliding plate 3 is in operation, the sliding seat 18 is moved by the cylinder 10 to drive the sliding seat 18 to move, thereby driving the sliding plate 3 to move on the surface of the track 2 and pulling the tape wheel 6 to pass through the bottom end of the movable frame 7, so that the tape wheel 6 sticks to the film at the bottom end of the movable frame 7. When the sliding plate 3 continues to pull the tape wheel 6, the tape wheel 6 will pull the film at the bottom end of the movable frame 7 and tear it off. When the sliding seat 18 moves to the position of one of the proximity switches 14, the proximity switch 14 will transmit a signal to the cylinder 10, thereby causing the cylinder 10 to pull the sliding seat 18 to move in the opposite direction, thereby realizing that the sliding plate 3 drives the tape wheel 6 to move repeatedly horizontally at the bottom end of the movable frame 7, thereby completing the film tearing operation of the graphite sheet film, avoiding the residual glue on the product surface caused by manual film tearing, and the uneven force on the film will cause the steel sheet position to shift, and the film tearing time is too long to affect the efficiency.

When the sliding plate 3 continues to pull the tape wheel 6, the tape wheel 6 will pull the film at the bottom end of the movable frame 7 and tear it off. When the sliding seat 18 moves to the position of one of the proximity switches 14, the proximity switch 14 will transmit a signal to the cylinder 10, so that the cylinder 10 pulls the sliding seat 18 to move in the opposite direction, so that the sliding plate 3 drives the tape wheel 6 to move repeatedly horizontally at the bottom end of the movable frame 7, thereby completing the film-tearing operation of the graphite film, avoiding the residual glue on the product surface caused by manual film tearing, and the position of the steel sheet will be offset due to uneven force on the film, and the film-tearing time is too long to affect the efficiency.
