After the film is broken, the two ends of the fracture fall on the corresponding side rollers 21 respectively, and continue to push up the movable plate B18. The rollers 21 on both sides respectively press the films on both sides of the cutter B22 against the corresponding side film cylinders and wind the film on the film cylinder. Then the motor B10 drives the newly replaced film cylinder to rotate and cooperate with the side rollers 21 to properly roll up the cling film. Then the motor A8 drives the turntable 7 to rotate to alternate the positions of the two insertion rollers B9. The staff removes the cling film cylinder that has been rolled up and replaces it with a new one.

[0033] Embodiment 2

[0034] like Figure 1 and Figure 2As shown, the utility model proposes a slitting structure, compared with the first embodiment, a circular groove and a vertical groove connected to the circular groove are arranged on the vertical plate 2, a turntable A3 is rotatably arranged in the circular groove, the turntable A3 is connected to the insertion roller A4, a brake pad 5 is slidably arranged in the vertical groove, and a hydraulic cylinder A6 is arranged in the vertical groove to drive the brake pad 5 to move toward the turntable A3.

[0035] In this embodiment, the motor B10 drives the film cylinder sleeved on the outside of the inserted roller B9 to rotate at a high speed, thereby quickly winding the cling film. However, after the current film cylinder is wound, the motor B10 needs to pause. During this process, the unloading film roller will continue to rotate due to its own inertia, resulting in excessive film discharge. After the film is excessively fed out, it is not only easy to be contaminated, but also will be attracted and entangled with each other. Therefore, when the motor B10 stops rotating, the hydraulic cylinder A6 presses down the brake pad 5 to brake the turntable A3.

[0036] A cling film processing device comprises the slitting structure in the above embodiment.

[0037] The implementation modes of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
