[0002] A printing press is a machine for printing words and images. Modern printing presses generally consist of mechanisms such as plate loading, inking, impression, and paper feeding. Its working principle is to first make the words and images to be printed into a printing plate, install it on the printing press, and then apply ink manually or by the printing press to the places with words and images on the printing plate, and then directly or indirectly transfer it to paper or other printing substrates, so as to reproduce the same printed matter as the printing plate.

[0003] The printing plate cylinder is also called a steel cylinder, which is divided into a hollow cylinder and a solid cylinder, a cylinder with a shaft and a cylinder without a shaft. It is generally used for plate making. The surface of the cylinder is plated with copper, and after the pattern is engraved by an intaglio electronic engraving machine, a layer of chromium is plated to carry out batch printing work.

[0004] However, during the printing process, the corrosiveness of the ink often damages the surface of the printing plate cylinder, thus reducing the printing resistance of the printing plate cylinder and increasing the printing cost; and when replacing the printing plate cylinder, the whole printing plate cylinder needs to be disassembled and then a printing plate cylinder with a different printing pattern needs to be reinstalled. This process is often inconvenient for installation operation due to the large weight of the printing itself. To solve the above problems, the utility model proposes a high printing resistance and environment-friendly printing plate cylinder. Content of the Utility Model

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0025] The examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present utility model, and should not be construed as a limitation to the present utility model.

[0026] Please refer to Figures 1 to 5 As shown, a high printing resistance and environmentally friendly printing plate roll includes a plate roll body. The plate roll body includes a core roll 1. Both ends of the core roll 1 are fixedly provided with roll shafts 101. A plurality of hollow chambers 102 are formed in the core roll 1. Both ends of the chambers 102 are open. The cross-section of the chambers 102 is fan-shaped. The chambers 102 are spaced apart and evenly distributed. The pattern roll surface 2 is detachably connected to the surface of the core roll 1.

[0029] According to the above solution, in the present utility model, an elastic rubber material is selected to make the pattern roller surface 2, and a corrosion-resistant coating is applied on the surface of the pattern roller surface 2. This can not only reduce the manufacturing cost of the pattern roller surface 2 and the self-weight of the pattern roller surface 2, but also effectively improve the tolerance of the pattern roller surface 2 to corrosive ink and increase the printing rate of the pattern roller surface 2.

[0030] As Figure 2 , Figure 3 and Figure 5 , a plurality of sliding grooves 103 are provided on the surface of the core roller 1. Only one end of each sliding groove 103 is open. Corresponding to the sliding grooves 103, a sliding rod 201 is fixedly connected to the inner side of the pattern roller surface 2. The size of the sliding rod 201 matches the size of the sliding groove 103. One end of the sliding rod 201 is aligned with one end of the pattern roller surface 2. Corresponding to the open end of the sliding groove 103, a fixing groove 105 is provided on one end side of the core roller 1. Two fixing rings 3 are detachably connected in the fixing groove 105. The two fixing rings 3 have matching sizes. After the two fixing rings 3 are spliced, their size matches the size of the fixing groove 105. The fixing ring 3 and the fixing groove 105 are detachably screwed together via a fixing nut 4. A plurality of connecting screw holes 301 are provided on both fixing rings 3 corresponding to the fixing nut 4, and fixing screw holes 104 are provided in the fixing groove 105 corresponding to the connecting screw holes 301.
