[0028] like Figure 1-Figure 2 As shown, the present application provides an embodiment of a slitting structure that is easy to install on a winding and slitting machine. The slitting structure that is easy to install on a winding and slitting machine is used for slitting the winding film material on the winding and slitting machine, and includes a fixed bracket 100, an upper cutter assembly, and a lower cutter assembly 300. The fixed brackets 100 are arranged in pairs and are located on both sides of the winding film material; the upper cutter assembly includes an upper cutter 230, a rotating shaft 210, a rotary control structure 250, and an upper cutter roller shaft 220. The upper cutter 230 is fixed to the upper cutter roller shaft 220, and both ends of the rotating shaft 210 are respectively fixed to two fixed brackets 100. The rotary control structure 250 is connected to one end of the rotating shaft 210 and is located outside the fixed bracket 100. The rotary control structure 250 is used to control the rotation angle of the rotating shaft 210. The cutter roller 220 is fixedly connected to the rotating shaft 210 and arranged in parallel, and the upper cutter roller 220 can be turned around the rotating shaft 210; the lower cutter assembly 300 includes a lower cutter and a lower cutter roller 310, the lower cutter is fixed on the lower cutter roller 310, and the two ends of the lower cutter roller 310 are respectively fixed on the fixed bracket 100; the upper cutter roller 220 is arranged in parallel with the lower cutter roller 310, and the film material penetrates between the upper cutter 230 and the lower cutter during operation and is divided into a set width. The upper cutter 230 and the lower cutter are arranged correspondingly, and the shaft sleeves are separated and positioned between the lower cutters. There are multiple upper cutters 230, and the spacing between two adjacent upper cutters 230 in the middle position is consistent with the set cutting length of the film material.

[0029] In this embodiment, the rotary control structure 250 can control the rotation angle of the rotating shaft 210, and change the rotation angle of the rotating shaft 210 so that the upper cutter roller 220 rotates around the rotating shaft 210. Changing the rotation angle of the rotating shaft 210 can flip the upper cutter roller 220 from the center position of the two fixed brackets 100 to the oblique upper position, so that the upper cutter roller 220 is close to the outside of the device, and the user can directly install or replace the upper cutter 230 on the outside of the device, increasing the installation and replacement space of the upper cutter 230, making the operation convenient and fast, and taking less time. After the upper cutter roller 220 and the upper cutter 230 are installed, the rotary control structure 250 restores the upper cutter roller 220 to the working position, improving the convenience of position control of the upper cutter 230.

[0030] like Figure 2 and Figure 3 As shown, in one embodiment, the lower cutter assembly 300 further includes a roller fixing block 320, a slide groove 110 is provided on the fixed bracket 100, rollers 3101 are provided at both ends of the lower cutter roller 310, the rollers 3101 are respectively embedded in the slide groove 110 and can roll in the slide groove 110, the lower cutter roller 310 is overlapped on the fixed bracket 100, and the roller fixing block 320 is symmetrically installed on the fixed bracket 100, so that the lower cutter roller 310 is fixed in the slide groove 110. The lower cutter roller 310 moves outward from the working position along the slide groove 110, close to the outside of the device, and the user can directly install or replace the lower cutter on the outside of the device, thereby increasing the installation and replacement space of the lower cutter, making the operation convenient and fast, and taking a short time. The slide groove 110 is arranged horizontally. Under no external force, the roller 3101 of the lower cutter roller 310 is stably engaged in the slide groove 110 to ensure the safe use of the lower cutter roller 310; after the roller fixing block 320 is released from restriction, the switching between the working position and the replacement position of the lower cutter roller 310 is convenient and fast.

[0031] In one embodiment, at the end position of the slide 110 toward the center of the fixed bracket 100, the two ends of the roller fixing block 320 are screwed to the top of the slide 110, fixing the roller 3101 to the end point of the slide 110. The contact surface between the roller 3101 and the roller fixing block 320 is an arc surface. The roller fixing block 320 has a simple structure and has a large contact area with the roller 3101, so that the fixing of the lower cutting roller 310 is more stable. The contact surface between the roller 3101 and the roller fixing block 320 is an arc surface, which can effectively disperse and reduce the impact of the roller fixing block 320 on the roller 3101, reduce the damage to the roller 3101, and help to extend the service life of the lower cutting roller 310.

[0032] like Figure 3As shown, in one embodiment, a stop block 120 is provided at the front end of the chute 110, and the top surface of the stop block 120 is higher than the upper end surface of the chute 110. The stop block 120 is used to prevent the lower cutter roller shaft 310 from rolling down from the chute 110. The stop block 120 protruding upward at the port on the front side of the chute 110 hinders the movement of the roller 3101, thereby ensuring the safety of the lower cutter roller shaft 310. In order to reduce the impact of the stop block 120 on the lower cutter roller shaft 310 and reduce the damage to the roller 3101 and the central axis of the lower cutter roller shaft 310, the connection surface between the stop block 120 and the chute 110 is an arc surface.

[0033] like Figure 1 and Figure 2 As shown, in one embodiment, the first connecting plate 2101 and the second connecting plate 2102 are respectively fixed at both ends of the rotating shaft 210, and the two ends of the upper cutter roller shaft 220 are respectively fixed on the first connecting plate 2101 and the second connecting plate 2102. The first connecting plate 2101 is located inside the fixed bracket 100, and the second connecting plate 2102 is located outside the fixed bracket 100. A servo motor 240 is installed on the second connecting plate 2102, and the servo motor 240 is connected to the upper cutter roller shaft 220 so that the upper cutter roller shaft 220 rotates autonomously. The fixed bracket 100 is plate-shaped, and the first connecting plate 2101 and the second connecting plate 2102 are respectively arranged parallel to the fixed bracket 100. The plate-shaped first connecting plate 2101 and the second connecting plate 2102 serve as a connecting structure to ensure that the connection between the upper cutter roller shaft 220 and the rotating shaft 210 is firm, and the position adjustment control of the upper cutter roller shaft 220 is accurate. The position setting of the first connecting plate 2101 and the second connecting plate 2102 not only ensures the installation connection of the upper cutter roller shaft 220, but also does not hinder the rotation control of the rotating shaft 210 by the rotary control structure 250. At the same time, the larger second connecting plate 2102 provides an installation position for the servo motor 240, which has a simple structure and reduces the influence of the servo motor 240 on the position adjustment of the upper cutter roller shaft 220. The autonomous rotation of the upper cutter roller shaft 220 facilitates the adjustment of the rotation speed of the upper cutter 230, helps to smooth the edge of the cut film material, and prevents the surface of the film material from being damaged.

[0034] The present application can be used on any slitting machine, especially in a winding slitting machine capable of cutting lithium battery film composite current collectors. It not only helps to improve the equipment installation efficiency and instrument debugging efficiency, but also reduces the surface damage of the film material that may be caused by the slitting of the composite current collector.

[0035] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all these improvements and changes should fall within the scope of protection of the claims attached to the utility model.

[0036] The above is an exemplary description of the utility model patent in conjunction with the accompanying drawings. It is obvious that the implementation of the utility model patent is not limited to the above-mentioned method. As long as various improvements are made by adopting the method concept and technical solution of the utility model patent, or the concept and technical solution of the utility model patent are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
