Detailed Implementation
[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] See Figures 1 to 4This embodiment discloses a slitting device, including a frame 100. The frame 100 is sequentially equipped with an unwinding roller 110, a guide roller 120, and a slitting roller 130. A support frame 200 extends outward from the side of the frame 100 where the slitting roller 130 is located. The height of the support frame 200 is lower than the surface height of the frame 100. The frame 100 is equipped with a guide member and a take-up roller 500. The guide member is close to the slitting roller 130. The guide member includes a guide rod 300. The guide rod 300 is provided with a plurality of guide plates 400 that can move along the guide rod 300. The guide plates 400 are connected to a moving member. The guide rod 300 is provided with a guide groove 310. The moving member is embedded in the guide groove 310. The movement of the moving member drives the guide plates 400 to move to adjust the distance between adjacent moving plates. The unwind roller 110 is used to unwind the film. The guide roller 120 provides guidance and tension. The slitting roller 130 is equipped with multiple equally spaced blades that can cut the entire film into multiple strips. The take-up roller 500 is located below the slitting roller, ensuring that the slitting roller 130 is positioned higher than the guide roller 120 and the take-up roller 500, thus guaranteeing film tension and slitting accuracy. The guide members restrict the film's transport direction, and the guide plate 400 can be moved to correct deviations during take-up.
[0019] The guide plate 400 is provided with a clearance hole 401, and the guide rod 300 passes through the clearance hole 401. The moving part includes a moving block 410 connected to the guide plate 400. The moving block 410 is embedded in the guide groove 310. The two sides of the moving block 410 are provided with retractable limiting blocks 412. The limiting blocks 412 fit against the side wall of the guide groove 310 to restrict the movement of the moving block 410. The movable block 410 contains two opposing movable drive plates 411. A connecting rod 413 is mounted on the side of the drive plate 411 facing the side wall of the mounting cavity 430. The connecting rod 413 extends out of the mounting cavity 430, and one end of the connecting rod 413 is connected to a limiting block 412. A spring 415 is fitted onto the connecting rod 413, and both ends of the spring 415 abut against the side wall of the mounting cavity 430 and the drive plate 411, respectively. A fixing post 420 is embedded in the mounting cavity 430, which pushes the drive plate 411 to move and causes the limiting block 412 to fit against the side wall of the guide groove 310. A first inclined surface 414 is provided on the top of the drive plate 411, and the first inclined surface 414 is inclined towards the center of the mounting cavity 430. The drive plate 411 is an arc-shaped structure protruding towards the side wall of the mounting cavity 430. When movement is required, the positioning pin is not placed in the mounting cavity 430. Under the action of the spring 415, the drive plate 411 moves toward the center of the mounting cavity 430, thereby moving the limiting block 412 away from the side of the guide groove 310. The guide plate 400, connected to the moving block 410, can move along the guide groove 310, thereby guiding and adjusting the conveying direction of the slit film. When the guide plate 400 needs to be fixed, the fixing pin 420 is inserted into the mounting cavity 430. When inserted, the fixing pin 420 pushes the drive plate 411 toward the inner wall of the mounting cavity 430, thereby moving the limiting block 412 toward the side wall of the guide groove 310. This causes the limiting block 412 to move against the side wall of the guide groove 310. The friction between the limiting block 412 and the side wall of the guide groove 310 restricts the movement of the moving block 410, thereby fixing the position of the guide plate 400.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
