The operation of the third conveyor belt drives the first driven wheel to rotate and then drives the second sprocket to rotate. The rotation of the second sprocket drives the fourth conveyor belt to rotate. The fourth conveyor belt drives another mobile clamping member to move. The first clamping member and the second clamping member are controlled by the first mobile motor and the second mobile motor to achieve the purpose of simultaneous movement.

[0015] As a further solution of the present invention: the first positioning plate includes a first positioning block inside, the side of the first positioning block is fixedly connected to a round rod, the lower side of the electromagnetic block is integrally connected to an L-shaped plate, and the L-shaped plate is rotatably connected to one end of the round rod.

[0016] By adopting the above technical solution, when the electromagnetic block moves, it drives the L-shaped plate to move upward, thereby causing the L-shaped plate and one end of the round rod to rotate. The above structure plays a role in moving the electromagnetic block.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] The roller of the cling film is put on the fixed shaft, one end of the cling film is pulled to be placed on the fixed clamping piece, and then the mobile driving piece is started to drive the mobile clamping piece to the fixed clamping piece to clamp one end of the cling film. Then, the mobile clamping piece clamps one end of the cling film, and under the action of the mobile driving piece, the cling film is pulled to the middle of the workbench. After completing the packaging of the cling film, the mobile clamping piece moves back to the fixed clamping piece to continue clamping the cling film, thereby realizing repeated and efficient film feeding. When the power is on, the electromagnetic block is magnetic and moves toward the direction of the positioning magnetic block to clamp the cling film between the electromagnetic block and the positioning magnetic block. It is worth noting that the cling film is squeezed and fixed when it is at the fixed clamping piece. Under the pull of the mobile clamping piece, the cling film can be moved.
