Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figures 1 to 4 A high-speed slitting machine, a frame 100 is provided with an unwinding roller 110 at one end, and two upper and lower winding rollers 120 are provided at the other end, and a slitting roller 130 is provided between the unwinding roller 110 and the two winding rollers 120. The film is unwound from the unwinding roller 110 and guided to the slitting roller 130 by a guide roller group, and is cut by the slitting roller 130 and divided into upper and lower paths and respectively wound by the winding roller 120.

[0022] The winding roller 120 includes a roller body 121, and connecting parts 200 are arranged at both ends of the roller body 121. A fixing part 300 is arranged on the frame 100, and the fixing part 300 includes a shaft body 301 and a fixing member 310. The frame 100 is connected to the shaft body 301 through a bearing so that the fixing part 300 can rotate on the frame 100. The fixing member 310 faces the winding roller 120, and a fixing sleeve 320 is sleeved on the fixing member 310. The fixing sleeve 320 can move along the axial direction of the fixing member 310. A connecting head 230 extending toward the fixing part 300 is arranged on the connecting part 200. When the fixing sleeve 320 moves so that its end face facing the winding roller 120 exceeds the end face of the fixing member 310 facing the winding roller 120, the fixing sleeve 320 and the fixing member 310 form a fixing groove, and the connecting head 230 is embedded in the fixing groove so that the winding roller 120 is connected to the fixing part 300, thereby driving the rotation of the winding roller 120.

[0023] A guide groove 311 is provided on the side wall of the fixing member 310, and a guide block 321 embedded in the guide groove 311 is provided on the fixing sleeve 320, so as to guide the moving direction of the fixing sleeve 320. A support plate 330 is also provided on the fixing member 310, and a first spring 340 is provided between the support plate 330 and the fixing sleeve 320. The first spring 340 is sleeved on the fixing member 310, and under normal conditions, the first spring 340 pushes the fixing sleeve 320 to move toward the winding roller 120. When installing the winding roller 120, the fixing sleeve 320 is pushed to move in the direction of the shaft body 301, so that the fixing sleeve 320 is away from the winding roller 120 to make space for the winding roller 120 to be embedded between the two fixing parts 300. When the connecting head 230 is aligned with the fixing piece 310, the fixing sleeve 320 is released so that the fixing sleeve 320 moves toward the winding roller 120 under the action of the first spring 340, so that the fixing sleeve 320 and the fixing piece 310 form a fixing groove and are connected to the connecting head 230, so that the winding roller 120 is fixed to the fixing part 300.

[0024] A telescopic groove 210 extending to the side wall of the connecting part 200 is radially arranged in the inner part of the connecting part 200, a limiting plate 500 is arranged in the telescopic groove 210, a limiting hole 520 is arranged on the limiting plate 500, and a limiting rod 322 is arranged on the fixing sleeve 320. When the limiting plate 500 extends out of the telescopic groove 210, the position of the limiting rod 322 corresponds to the position of the limiting hole 520. When the fixing sleeve 320 moves toward the direction of the winding roller 120, the limiting rod 322 is inserted into the limiting hole 520, so that the winding roller 120 is fixed to the fixing part 300, further ensuring the stability of the connection between the fixing part 300 and the winding roller 120.

[0025] A first limiting groove 510 is provided on the limiting plate 500, a first baffle 211 extending into the first limiting groove 510 is provided in the telescopic groove 210, a second spring 530 in contact with the first baffle 211 is provided in the first limiting groove 510, and under normal circumstances, the second spring 530 limits the limiting plate 500 from extending out of the telescopic groove 210.

[0026] The connector 230 is provided with a driving slot 220 connected to the telescopic slot 210, and a driving member 400 is provided in the driving slot 220, which can move along the driving slot 220 and has one end extending into the telescopic slot 210. The end of the driving member 400 extending into the telescopic slot 210 is provided with a first guiding inclined surface 420, and the limiting plate 500 is provided with a second guiding inclined surface 540 matching the first guiding inclined surface 420. When the driving member 400 moves toward the telescopic slot 210, the first guiding inclined surface 420 moves along the second guiding inclined surface 540, thereby pushing the limiting plate 500 to extend out of the telescopic slot 210.

[0027] The driving member 400 is provided with a second limiting groove 410, and a second baffle plate 221 extending into the second limiting groove 410 is provided in the driving groove 220, and a third spring 222 in contact with the second baffle plate 221 is provided on the second limiting groove 410. Under normal conditions, the third spring 222 pushes the driving member 400 so that the end portion thereof facing the fixing portion 300 extends out of the driving groove 220. When the winding roller 120 is inserted between the two fixing portions 300, the portion of the driving member 400 extending out of the driving groove 220 is squeezed, and the driving member 400 moves toward the telescopic groove 210, thereby driving the limiting plate 500 to extend out of the telescopic groove 210.

[0028] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
