[0002] The printing roller is one of the core components of a printing press. It is mainly used to carry the printing plate and transfer the graphic information on the printing plate to the substrate. Most existing printing rollers are made of aluminum or nylon. However, aluminum, as a metal material, has a large mass disadvantage when used in high-speed printing presses, while nylon printing rollers have insufficient temperature resistance. Therefore, it is necessary to solve these problems. Summary of the Invention

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-2 A composite material printing roller includes a hollow fiberglass tube layer 1, a carbon fiber tube layer 5 coaxially fixed outside the fiberglass tube layer 1, and a composite buffer layer disposed between the fiberglass tube layer 1 and the carbon fiber tube layer 5.

[0018] According to the structure provided in this embodiment, the composite material printing roller provided in this embodiment sets the carbon fiber tube layer 5 as the surface layer that directly supports the printing plate, which has the advantages of high temperature resistance, light weight, and high dimensional accuracy; the broken fiber tube layer 1 is set as the inner layer that is directly connected to the transmission mechanism, which has the advantages of high connection strength, good rigidity, and light weight; at the same time, through the set composite buffer layer, the vibration energy generated during high-speed printing can be effectively absorbed and reduced, ensuring the stability of high-speed printing.

[0019] In another embodiment of this application, please refer to [the relevant document / reference]. Figure 1 and Figure 2The composite buffer layer includes a buffer cotton layer 2 and a fiberglass layer 3 sequentially wrapped around the outer wall of the fiberglass tube layer 1. The fiberglass layer 3 is closer to the carbon fiber tube layer 5 than the buffer cotton layer 2. According to the structure provided in this embodiment, the composite buffer layer provided in this embodiment includes a buffer cotton layer 2 and a fiberglass layer 3 sequentially wrapped around the outer wall of the fiberglass tube layer 1. The outer wall of the fiberglass layer 3 is attached to the inner wall of the carbon fiber tube layer 5. Here, the above-described structure of this embodiment is preferably applicable to composite material printing rollers where the outer diameter of the carbon fiber tube layer 5 (that is, the outer diameter of the entire printing roller) is between 75mm and 88mm. For example, when the outer diameter of the carbon fiber tube layer 5 is 75.867mm, 77.888mm, 79.909mm, 80.920mm, or 87.994mm, the above-described composite buffer layer structure is preferred. The inner wall of the carbon fiber tube layer 5 is directly bonded to the outer wall of the glass fiber layer 3. At this time, since the outer diameter of the entire printing roller is small, the centrifugal force and vibration generated during high-speed printing are small. The composite buffer layer composed of the glass fiber tube layer 1, the buffer cotton layer 2, and the glass fiber layer 3 can achieve a good vibration absorption and damping effect. The structure is simple and reliable.

[0020] In another embodiment of this application, please refer to [the relevant document / reference]. Figure 1 and Figure 3 The composite buffer layer also includes a polyurethane filling layer 4 wrapped around the outer wall of the fiberglass layer 3 and internally connected to the carbon fiber tube layer 5. That is, according to the structure provided in this embodiment, the composite buffer layer provided in this embodiment includes a buffer cotton layer 2 wrapped around the outer wall of the fiberglass tube layer 1 and a polyurethane filling layer 4 internally connected to the carbon fiber tube layer 5, with a fiberglass layer 3 disposed between the buffer cotton layer 2 and the polyurethane filling layer 4. The structure described above in this embodiment is preferably applicable to composite printing rollers where the outer diameter of the carbon fiber tube layer 5 (i.e., the outer diameter of the entire printing roller) is between 88mm and 192mm. For example, when the outer diameter of the carbon fiber tube layer 5 is 89.005mm, 110.227mm, 118.312mm, 140.545mm, 152.672mm, 162.778mm, 177.937mm, or 191.075mm, the above-mentioned composite buffer layer structure is preferred. Thus, the sandwich-like double composite structure formed by the fiberglass tube layer 1, the buffer cotton layer 2, the fiberglass layer 3, and the polyurethane filling layer 4 can ensure good vibration absorption and buffering effect, avoid excessive elastic swaying between the inner and outer layers, and significantly reduce the overall weight, thereby ensuring high-speed printing quality.

[0021] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 3The carbon fiber tube layer 5 includes a carbon fiber matrix layer 7 formed by winding carbon fibers and a carbon cloth layer 6 attached to the outer wall of the carbon fiber matrix layer 7. According to the structure provided in this embodiment, the carbon fiber matrix layer 7 formed by winding and curing carbon fibers in a set manner has the advantage of high strength. Furthermore, attaching a carbon cloth layer 6 to the carbon fiber matrix layer 7 can, on the one hand, result in a texture with strong visual appeal that has 3D visual characteristics, and on the other hand, reduce the surface roughness value, resulting in a smooth support surface, which is beneficial to improving printing quality.

[0022] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 3 The composite material printing roller also includes end caps 8 disposed at both ends of the fiberglass tube layer 1, the carbon fiber tube layer 5 and the composite buffer layer. The end caps 8 are located within the axial projection area of ​​the fiberglass tube layer 1, the carbon fiber tube layer 5 and the composite buffer layer. According to the structure provided in this embodiment, the end caps 8 in this embodiment adopt an aluminum alloy structure, which is beneficial to enhance the overall strength of the composite material printing roller and improve the high-speed printing performance of the printing press.

[0023] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 3 The carbon fiber matrix layer 7 is formed by winding and curing T700 carbon fiber filaments in a set number of layers. Using T700 carbon fiber filaments not only achieves high strength but also has a better cost advantage. Here, the T700 carbon fiber filaments are pre-coated with an adhesive curing agent, and the curing method can adopt existing technology.

[0024] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 3 A cutting groove 9 is provided on the outer wall of the carbon fiber tube layer 5. The cutting groove 9 is parallel to the axial direction of the carbon fiber tube layer 5. In this way, after the printing plate is attached to the surface of the carbon fiber tube layer 5, the beginning and end positions of the printing plate are located at the cutting groove 9. Since there are bound to be dimensional errors during the production of the printing plate, when the beginning and end edges of the printing plate overlap, the excess part of the printing plate can be cut off along the cutting groove 9 to ensure that the printing plate is firmly attached to the surface of the carbon fiber tube layer 5. The joint is smooth and without protrusions to ensure printing quality. It also facilitates the replacement of the printing plate, which helps to improve the convenience of using this composite material printing roller and thus improves the production efficiency of the printing press.
