[0024] like Figure 1 and Figure 6As shown, the rear end of the plate roller 1 is fixed with a rear roller pillow 3, and the front end of the plate roller 1 is fixed with a front roller pillow 5. A plate roller reel mounting hole is opened in the plate roller 1, a rear roller pillow reel mounting hole is opened in the rear roller pillow 3, and a front roller pillow reel mounting hole is opened in the front roller pillow 5. A reel 4 is rotatably installed in the rear roller pillow reel mounting hole, the plate roller reel mounting hole and the front roller pillow reel mounting hole, so that the reel 4 can rotate in the plate roller 1, the rear roller pillow 3 and the front roller pillow 5. A PS plate limit block 17 is fixed on the plate roller 1 corresponding to the position of the reel 4. Two centrally symmetrical plate drawing openings 4.1 are provided on the reel 4 between the rear roller pillow 3 and the front roller pillow 5.

[0025] like Figure 1-3 and Figure 7 As shown, a rear fixed block bottom plate 18 is fixed on the rear roller pillow 3, and a rear fixed block 10 is fixed on the rear fixed block bottom plate 18. The rear swivel seat 19 is hinged between the rear fixed block bottom plate 18 and the rear fixed block 10, so that the rear swivel seat 19 can swing between the rear fixed block 10 and the rear fixed block bottom plate 18. A rear connecting rod mounting hole is opened on the rear swivel seat 19, and one end of the rear connecting rod 8 is slidably mounted in the rear connecting rod mounting hole on the rear swivel seat 19, so that the rear connecting rod 8 can slide in the rear connecting rod mounting hole on the rear swivel seat 19. The other end of the rear connecting rod 8 is hinged to the rear swivel block 2 through the rear pin shaft 7, and a rear compression spring 9 is installed on the rear connecting rod 8 between the rear swivel seat 19 and the rear swivel block 2;

[0026] like Figure 1 、 Figure 4 、 Figure 5 and Figure 8 As shown, a front fixed block base plate 20 is fixed on the front roller pillow 5, and a front fixed block 14 is fixed on the front fixed block base plate 20. The front swivel seat 21 is hinged between the front fixed block base plate 20 and the front fixed block 14, so that the front swivel seat 21 can swing between the front fixed block 14 and the front fixed block base plate 20. A front link mounting hole is opened on the front swivel seat 21, and one end of the front link 12 is slidably mounted in the front link mounting hole on the front swivel seat 21, so that the front link 12 can slide in the front link mounting hole on the front swivel seat 21, and the other end of the front link 12 is hinged to the front swivel block 6 through a front pin shaft 11, and a front compression spring 13 is installed on the front link 12 between the front swivel seat 21 and the front swivel block 6;

[0027] A buffer mounting block 16 is fixed on the front roller support 5 , and a piston-type buffer 15 is fixed on the buffer mounting block 16 . The piston rod end of the piston-type buffer 15 is in contact with the front rotation block 6 .

[0028] The rear end of the reel 4 is fixed to the rear rotating block 2 via two centrally symmetrical keys.

[0029] The front end of the reel 4 is fixed to the front rotating block 6 via two centrally symmetrical keys.

[0030] The upper surface of the rear swivel seat 19 is provided with an upwardly protruding rear swivel seat upper convex shaft, and the lower surface of the rear swivel seat 19 is provided with a downwardly protruding rear swivel seat lower convex shaft, the rear swivel seat upper convex shaft and the rear swivel seat lower convex shaft are coaxially arranged, a rear swivel seat lower convex shaft mounting hole is provided on the rear fixed block bottom plate 18, and a rear swivel seat upper convex shaft mounting hole is provided on the rear fixed block 10, the rear swivel seat lower convex shaft mounting hole and the rear swivel seat upper convex shaft mounting hole are coaxially arranged, the rear swivel seat upper convex shaft is installed in the rear swivel seat upper convex shaft mounting hole, and the rear swivel seat lower convex shaft is installed in the rear swivel seat lower convex shaft mounting hole.

[0031] The upper surface of the front swivel seat 21 is provided with an upwardly protruding front swivel seat upper convex shaft, and the lower surface of the front swivel seat 21 is provided with a downwardly protruding front swivel seat lower convex shaft, the front swivel seat upper convex shaft and the front swivel seat lower convex shaft are coaxially arranged, a front swivel seat lower convex shaft mounting hole is provided on the front fixed block bottom plate 20, and a front swivel seat upper convex shaft mounting hole is provided on the front fixed block 14, the front swivel seat lower convex shaft mounting hole and the front swivel seat upper convex shaft mounting hole are coaxially arranged, the front swivel seat upper convex shaft is installed in the front swivel seat upper convex shaft mounting hole, and the front swivel seat lower convex shaft is installed in the front swivel seat lower convex shaft mounting hole.

[0032] During use, the PS plate 100 is loaded into the plate roller 1 and axially positioned by the PS plate limit block 17. After the plate roller 1 rotates one circle, the tail of the PS plate 100 is loaded into the plate roller 1. When an external force acts on the plate pulling force point 6.1 of the front rotating block 6, the front rotating block 6 rotates counterclockwise, causing the reel 4 to rotate counterclockwise, so that the plate pulling opening 4.1 on the reel 4 tightens the tail of the PS plate 100. Under the action of the front compression spring 13, the line connecting the front rotating seat 21, the front connecting rod 12, and the hinge point of the front rotating block 6 exceeds the rotation point of the front rotating block 6 to form a dead point, ensuring that the PS plate 100 is always in a taut state. The tension of the PS plate 100 can be adjusted by the buffer 15. When external force acts on the opening force point 6.2 of the front rotating block 6, the front rotating block 6 rotates clockwise and causes the reel 4 to rotate clockwise, causing the plate pulling mouth 4.1 of the reel 4 to open. Under the action of the front compression spring 13, the plate pulling mouth 4.1 of the reel 4 remains open. At this time, the tail of the PS plate 100 bounces open and the plate can be unloaded.

[0033] In the present invention, the plate drawing opening 4.1 of the PS plate 100 is disposed on the reel 4, and two centrally symmetrical plate drawing openings 4.1 are provided on the reel 4, with the two plate drawing openings 4.1 spaced 180 degrees apart. Therefore, when one of the plate drawing openings 4.1 of the PS plate 100 wears out after several years, the plate can be used by simply rotating the reel 4 180 degrees and reassembling the parts next to the reel 4. Therefore, the present invention has the advantages of simple structure, easy assembly and disassembly, high accuracy, and high plate drawing precision.

[0034] Finally, it should be noted that the above specific implementation methods are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to examples, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
