[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figures 1-5As shown in the figure, a paper positioning mechanism for a die-cutting machine includes a die-cutting machine body 1, a storage plate body 13, a conveyor belt arranged on the surface of the die-cutting machine body 1, and a fixing plate 2 fixedly connected to the surface of the conveyor belt. One side of the top of the fixing plate 2 is installed with a rotating plate 3 through a spring hinge. A clamping groove 4, a sliding groove 17 and a positioning groove 12 are opened at the top of the fixing plate 2. A connecting component 5 is arranged inside the clamping groove 4. Long plates 6 and moving disks 7 respectively slide through both sides of the surface of the connecting component 5. The surface of the long plate 6 is in contact with the surface of the storage plate body 13. First compression springs 8 and second compression springs 9 are respectively fixedly connected to the surfaces of the long plate 6 and the moving disk 7. A guiding component 10 is installed on the surface of the moving disk 7. A positioning plate 11 is fixedly connected below the surface of the moving disk 7. The surface of the positioning plate 11 is in contact with the inner wall of the positioning groove 12. By using the cooperation of the positioning plate 11 and the positioning groove 12, the positions of the moving disk 7 and the long plate 6 can be restricted to increase the stability of the state of the storage plate body 13. Rectangular plates 14 are fixedly connected to both sides of the surface of the rotating plate 3. A cross bar 15 movably penetrates through the surface of the storage plate body 13. The cross bar 15 movably penetrates through one rectangular plate 14, and one end of the cross bar 15 is threadedly penetrated through the other rectangular plate 14. Accordingly, the position between the storage plate body 13 and the rectangular plate 14 can be fixed by the cross bar 15. An adjusting mechanism 18 is arranged inside the sliding groove 17. A sliding plate 19 is threadedly sleeved on the surface of the adjusting mechanism 18. The surface of the sliding plate 19 is slidably connected to the inner wall of the sliding groove 17. A clamping plate 20 is fixedly connected to the top of the sliding plate 19. The surface of the clamping plate 20 is in contact with the surface of the storage plate body 13. A top plate 16 is fixedly connected to the top of the rotating plate 3. The heights of the top plate 16, the storage plate body 13 and the top of the clamping plate 20 are equal. Accordingly, the position of the paper can be positioned by the top plate 16, the storage plate body 13 and the clamping plate 20.

[0024] The connecting component 5 includes a clamping plate 51, a vertical plate 52 and a connecting rod 53. The clamping plate 51 is fixedly connected to the bottom of the rotating plate 3. The surface of the clamping plate 51 is in contact with the inner wall of the clamping groove 4. The vertical plate 52 is fixedly connected to one side of the top of the clamping plate 51. The connecting rod 53 fixedly penetrates through the surface of the vertical plate 52. The long plate 6 and the moving disk 7 are respectively slidably sleeved on both sides of the surface of the connecting rod 53. The first compression spring 8 and the second compression spring 9 are respectively sleeved on both sides of the surface of the connecting rod 53. One ends of the first compression spring 8 and the second compression spring 9 are respectively fixedly connected to the surfaces of both sides of the vertical plate 52. Accordingly, when the staff moves the long plate 6, the contact between the long plate 6 and the surface of the storage plate body 13 can be released, so that it is convenient for the staff to replace the storage plate body 13.

[0025] The guiding assembly 10 includes an extension plate 101, a guiding rod 102 and a limiting plate 103. The extension plate 101 is fixedly connected to the surface of the moving disk 7. The guiding rod 102 slidably penetrates through the surface of the extension plate 101. The limiting plate 103 is fixedly connected to one end of the guiding rod 102. The surface of the limiting plate 103 is fixedly connected to one end of the connecting rod 53. The other end of the guiding rod 102 is in contact with the surface of the vertical plate 52. Accordingly, when the staff moves the moving disk 7, the moving disk 7 approaches the vertical plate 52. At this time, the extension plate 101 moves accordingly. Thus, the movement of the moving disk 7 can be guided to increase the stability of the moving disk 7 and the positioning plate 11 during movement.

[0026] A limiting disk is fixedly connected to the other end of the connecting rod 53. A limiting groove is formed in the surface of the long plate 6. The surface of the limiting disk is in contact with the inner wall of the limiting groove. Accordingly, the movement range of the long plate 6 can be limited.

[0027] The adjusting mechanism 18 includes a rotating shaft 181, a lead screw 182 and an adjusting rod 183. The rotating shaft 181 rotatably penetrates through the fixing plate 2. The number of the lead screws 182 is two. The two lead screws 182 are respectively fixedly connected to both ends of the rotating shaft 181. The thread directions of the two lead screws 182 are opposite. The adjusting rod 183 is fixedly connected to one end of one of the lead screws 182 and rotatably penetrates through the fixing plate 2. A turntable is fixedly connected to one end of the adjusting rod 183. The sliding plate 19 is threadedly sleeved on the surface of the lead screw 182. When the staff rotates the turntable, the rotating shaft 181 can be driven to rotate through the lead screw 182. Accordingly, when the two lead screws 182 rotate simultaneously, the position of the clamping plate 20 can be adjusted through the sliding plate 19 so as to limit the position of the paper through the clamping plate 20.

[0028] Working principle: First, the staff uses the cooperation of the cross bar 15 and the rectangular plate 14 to limit the position of one end of the storage plate body 13. Then, under the action of the elastic force of the first compression spring 8, the long plate 6 moves and contacts the surface of the storage plate body 13, so as to limit the position of the storage plate body 13. Then, the staff can place the paper on the storage plate body 13 and rotate the turntable. The adjusting mechanism 18 drives the sliding plate 19 to move, and the position of the paper can be fixed by the clamping plate 20. At this time, the long plate 6 and the top plate 16 are used in cooperation to further limit the position of the paper, so as to reduce the possibility of the paper shifting during the die-cutting process, thus facilitating the subsequent die-cutting processing. During the die-cutting process, the conveyor belt drives the fixed plate 2 to move, so as to perform die-cutting processing on the paper through the die-cutting machine body 1. After the processing is completed, the fixed plate 2 drives the paper to move out. Then, the staff can rotate the storage plate body 13 while pulling the moving disk 7. At this time, the positioning plate 11 can be moved out of the positioning groove 12. During this process, the storage plate body 13 can drive the paper to rotate. After that, the staff lifts the long plate 6 to release the contact between the long plate 6 and the surface of the storage plate body 13, and thus the fixation of the long plate 6 on the position of the paper can be released, so that the staff can smoothly remove the paper.
