DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] The utility model provides Figure 1-4 The diffusion film cutting device shown in the figure includes a base plate 100, a die-cutting device 101, a material feeding mechanism 200 and a tensioning mechanism 300. The device also includes a reeling mechanism for the diffusion film raw material and a reeling mechanism for the waste material after the diffusion film is cut, so that the diffusion film is kept in a continuous transmission state above the base plate 100. The die-cutting device 101 is fixedly installed on one side of the top of the base plate 100. The die-cutting device 101 is used for die-cutting the diffusion film. The material feeding mechanism 200 is fixedly installed on the top of the base plate 100, and the material feeding mechanism 200 feeds the die-cutting part on the diffusion film by rotating at the same speed as the die-cutting device 101. The tensioning mechanism 300 is arranged on both sides of the material feeding mechanism 200. The tensioning mechanism 300 is used for tensioning the diffusion film during the transmission process. In this embodiment, the die-cutting device 101 is mainly composed of two mutually matched die-cutting rollers, which are driven by gears. The die-cutting device 101 can realize synchronous and anteroposterior rotation, and the rotation speed is the same as the transmission speed of the diffusion film, so as to achieve continuous die-cutting processing of the diffusion film, thereby cutting out the diffusion film of the required size and thickness. The diffusion film after die-cutting by the die-cutting device 101 will stick together. At this time, due to the tensioning effect of the two tensioning mechanisms 300 on the continuous diffusion film, when the die-cut area on the diffusion film reaches the lower position of the material diverting mechanism 200, since the rotation speed of the material diverting mechanism 200 is the same as the transmission speed of the diffusion film, the material diverting mechanism 200 can provide a downward thrust on the die-cut area on the diffusion film, thereby pushing the die-cut area on the diffusion film downward and separating it from the continuous diffusion film, thereby achieving the purpose of automatic material separation, avoiding material loss, and facilitating the unloading of the diffusion film after die-cutting, and also eliminating the tedious and high cost of manual unloading, better meeting actual use needs.

[0023] The first and second fixing plates 201 are connected to the bottom plate 100 at the ends of the first fixing plates 201 and the bottom plate 100 is fixedly connected to the top of the bottom plate 100. The outer wall of the rotating shaft 202 is fixedly sleeved with a connecting ring 203. The outer wall of the connecting ring 203 is fixedly connected with a material-discharging rod 204. The number of the material-discharging rods 204 is the same as the number of radial die-cutting areas of the outer wall of the die-cutting roller of the die-cutting device 101, and they are installed in the same position. In this way, when the area on the diffusion film to be die-cut by the die-cutting device 101 moves to the bottom of the material-discharging mechanism 200, the end position of the material-discharging rod 204 away from the rotating shaft 202 can be rotated to the vertical downward position and extend to the lower position of the diffusion film, thereby pushing down the diffusion film material at the die-cutting position on the diffusion film, and utilizing the thrust to achieve the purpose of separation, thereby completing the automatic discharging of the die-cut diffusion film. The number of the connecting rings 203 is the same as the number of axial die-cutting areas of the outer wall of the die-cutting roller of the die-cutting device 101.

[0024] In a preferred embodiment, the connecting ring 203 is composed of an upper frame 231 and a lower frame 232. The two ends of the upper frame 231 close to the lower frame 232 are fixedly connected to the positioning plug 233, and the two ends of the lower frame 232 close to the upper frame 231 are provided with a card slot matching the positioning plug 233, and a locking member is provided between the positioning plug 233 and the card slot; the locking member includes a locking bolt 235, and the side wall of the lower frame 232 is provided with a receiving groove 234, and the inner wall of the receiving groove 234 is provided with a screw hole connected to the positioning plug 233, the outer wall of the locking bolt 235 is threadedly connected to the screw hole, and the middle part of the positioning plug 233 is provided with a card slot that matches the locking bolt 235 The matching through holes form a connecting ring 203 through the split structure of the upper frame 231 and the lower frame 232, so that the connecting ring 203 can be detached from the outer wall of the rotating shaft 202, so as to facilitate the adjustment of the position of the connecting ring 203 on the rotating shaft 202, thereby better adapting to the use of the die-cutting device 101. After the upper frame 231 and the lower frame 232 are spliced ​​together, the positioning plug 233 is inserted into the card slot, and the locking bolt 235 is screwed from the receiving slot 234 into the screw hole of the positioning plug 233 to limit and fix the positioning plug 233. A rubber ring can be added between the connecting ring 203 and the rotating shaft 202 to increase friction resistance and improve the stability of the installation.

[0025] Furthermore, the outer walls of the upper frame 231 and the lower frame 232 are fixedly connected with a connecting screw 206, and a connecting screw hole 205 is opened at one end of the material removing rod 204 close to the connecting ring 203. The outer wall of the connecting screw 206 is threadedly connected to the inner wall of the connecting screw hole 205. The connecting screw hole 205 on the material removing rod 204 cooperates with the connecting screw 206 on the outer wall of the connecting ring 203, so that the material removing rod 204 can be disassembled and assembled on the outer wall of the connecting ring 203, so that the material removing rod 204 of different lengths can be replaced according to actual usage requirements.

[0026] In other embodiments, the tensioning mechanism 300 includes two second fixed plates 301, which are symmetrically fixedly connected to the top of the base plate 100. Two tensioning rollers 302 are rotatably connected between the two second fixed plates 301, and two adjacent tensioning rollers 302 are vertically spaced apart. The diffusion film is wound in a serpentine trajectory between the two tensioning rollers 302 of the same tensioning mechanism 300, which can enhance the tension of the diffusion film during transmission, so that the material stripping rod 204 can provide a stable downward thrust to peel the die-cut diffusion film from the continuous diffusion film.

[0027] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
