[0054] The rotating disk 9 is fixedly mounted on the first rotating roller 8.

[0055] During operation, the first motor 7 is started, which drives the first rotating roller 8, which is fixedly connected to its output end, to rotate. The first rotating roller 8 drives the rotating disk 9 to rotate, and the rotating disk 9 is used to change different winding mechanisms.

[0061] The electric telescopic rod 12 is fixedly mounted on the U-shaped fixing plate 3;

[0063] The support rod 14 is fixedly mounted on the support plate 13 and is slidably connected to the U-shaped fixing plate 3.

[0064] During operation, when it is necessary to change to a different winding mechanism, the electric telescopic rod 12 is activated. The electric telescopic rod 12 drives the support plate 13 to move towards the U-shaped fixed plate 3, so that the support plate 13 moves out of the winding roller 11, thereby facilitating the rotation of the winding mechanism to change to a different winding mechanism. After the change, the electric telescopic rod 12 is activated, and the electric telescopic rod 12 drives the support plate 13 to move away from the U-shaped fixed plate 3, so that the winding roller 11 moves into the hole of the support plate 13, thereby providing support for the winding mechanism. The support rod 14 plays a supporting role.

[0065] The hot melt cutting assembly 4 is fixedly mounted on the U-shaped fixing plate 3; it is used to cut the lithium battery separator film between the two take-up rollers 11.

[0066] V-shaped collection trough 5 is provided on the collection plate 1; used for collecting waste materials;

[0071] During operation, the hydraulic cylinder 15 is activated, which drives the compression plate 16 to move inside the compression box 6. The compression plate 16 compresses the waste material inside the compression box 6 and pushes the compressed waste material onto the conveyor belt 20.

[0072] Reference Figures 3 to 5 In a preferred embodiment, a transport mechanism is disposed on the compression box 6 for transporting the compressed waste material out of the compression box 6. The transport mechanism includes:

[0077] The compression box 6 is provided with a transport outlet 21, which is used by the transport mechanism to transport the compressed waste material out of the compression box 6.

[0078] During operation, the transport motor 17 is started, which drives the first rotating roller 18, which is fixedly connected to its output end, to rotate. The first rotating roller 18 and the second rotating roller 19 work together to drive the transport belt 20 to rotate. The transport belt 20 transports the compressed waste material from the transport outlet 21 out of the compression box 6, realizing the automation of waste cleaning, thereby reducing downtime and improving processing efficiency.

[0079] Working principle: The take-up motor 10 is started, driving the take-up roller 11 to rotate. The take-up roller 11 continuously winds up the release film. When the take-up roller 11 is fully wound, the hot melt cutting assembly 4 is activated to cut the release film. The waste generated from the melting and cutting falls into the V-shaped collection groove 5 on the collection plate 1, and then along the V-shaped collection groove 5 into the compression box 6. The electric telescopic rod 12 is activated, driving the support plate 13 to move towards the U-shaped fixed plate 3, causing the support to detach from the take-up roller 11. The first motor 7 is activated, driving the first rotating roller 8 to rotate. The first rotating roller 8 drives the rotating disk 9 to rotate, and the rotating disk 9 replaces the new take-up roller. The winding mechanism is activated by starting the electric telescopic rod 12, which drives the support plate 13 to move away from the U-shaped fixed plate 3, thereby supporting and fixing the winding roller 11. The winding mechanism is then activated to continue winding. The hydraulic cylinder 15 is activated to compress the waste material falling into the compression box 6 and push the compressed waste material onto the conveyor belt 20. The conveyor motor 17 is activated to drive the first rotating roller 18 to rotate. The first rotating roller 18 and the second rotating roller 19 work together to drive the conveyor belt 20 to rotate. The conveyor belt 20 transports the compressed waste material out of the compression box 6 from the conveyor outlet 21, thus automating the waste cleaning process.
