[0033] See also Figure 1 , a printing plate positioning device includes a supporting structure and four positioning structures.

[0034] See also Figure 2 The supporting structure includes a base 1, which is disc-shaped. A positioning plate 2 is fixedly installed in the middle of the upper end of the base 1, and a printing plate 3 is placed on the upper end of the positioning plate 2. Four trapezoidal blocks 4 are fixedly installed on the upper edge of the base 1. The four trapezoidal blocks 4 are distributed in a circle with the center of the base 1 as the center, and the distance between every two adjacent trapezoidal blocks 4 is equal.

[0035] See also Figure 3-8 The positioning structure includes a sleeve 5, which has two grooves on the end face of the sleeve 5 away from the trapezoidal block 4. The grooves are circular and convex in cross section, and the aperture of the end away from the trapezoidal block 4 is smaller than that of the end close to the trapezoidal block 4. The sleeve 5 is fixedly installed with the trapezoidal block 4, and two telescopic rods 6 are connected inside the sleeve 5. The telescopic rods 6 are inserted into the sleeve 5 through the grooves of the sleeve 5. One sleeve 5 is inserted with two telescopic rods 6, and there are eight telescopic rods 6 in total. The end of the telescopic rod 6 close to the sleeve 5 is clamped inside the groove of the sleeve 5, and the clamped part is smaller than the aperture of the end face of the sleeve 5. The ends of the two telescopic rods 6 away from the sleeve 5 are fixedly installed with the same clamp 7, which is made of rubber. The clamp 7 consists of a cuboid and a cube. A square groove is provided on the side of the cube away from the telescopic rod 6, and a rubber Rubber pad 8, rubber pad 8 is installed on the upper and lower surfaces of the square groove, a number of convex points are provided on the surface of rubber pad 8, and the convex points are distributed in a rectangular shape. A rectangular groove is provided on the upper end of the clamp 7, and two bolts 9 are fixedly installed on the upper end of the clamp 7. The upper end cover of the clamp 7 is provided with a compression cover 10 penetrated by the bolt 9, and a rectangular protrusion is provided at the lower end of the compression cover 10. The compression cover 10 is provided with two circular through holes in the upper and lower directions. The bolt 9 is plugged with the compression cover 10 through the circular through holes, and the protrusion at the lower end of the compression cover 10 is plugged into the groove at the upper end of the clamp 7. Thin sheets 11 are fixedly installed on both sides of the compression cover 10, and a nut 12 is connected to the upper end of each bolt 9.

[0036] In summary, the printing plate positioning device has thin sheets 11 installed on both sides of the compression cover 10, and nuts 12 are threadedly connected on the top thereof. When the nuts 12 are tightened, the thin sheets 11 on both sides exert a downward pressure on the clamp 7. At the same time, since the clamp 7 is made of rubber material and is easy to deform, the clamp 7 clamps the printing plate 3 and has a fixing effect.

[0037] The printing plate positioning device, by providing the shaft sleeve 5 and the retractable rod, allows the positioning structure to be retractable and retractable. When disassembling, it is only necessary to unscrew the nut 12 and then open it in all directions. When clamping, each positioning structure is first pulled to a suitable position and then clamped by the above-mentioned nut 12, so that the printing plate 3 is positioned.

[0038] The printing plate positioning device has square rubber pads 8 installed inside the clamp 7. The rubber pads 8 are distributed in a rectangular shape, so that the friction between the rubber pads 8 and the clamp 7 is increased, so that the printing plate 3 will not slide easily, and the printing plate 3 is further fixed, so that the positioning of the printing plate is more accurate.
