[0018] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0019] The embodiment of the present application provides a chrome-plated printing roller with cooling protection. The chrome-plated printing roller with cooling protection can cool the printing roller body through a heat dissipation component to prevent the printing roller body from generating large amounts of heat on the surface and inside when in operation, thereby preventing damage to the printing roller. The roller is more convenient to use.

[0020] The chrome-plated printing roller with cooling protection is described in detail below. It should be noted that the description order of the following embodiments is not intended to limit the preferred order of the embodiments.

[0021] The present application is described in detail below in conjunction with the accompanying drawings and specific implementation methods. Figure 1-4 In the embodiment, a chrome-plated printing roller with cooling protection is provided, comprising: a printing roller body 1, a rotating shaft 11 is fixedly connected to both ends of the printing roller body 1, a plurality of heat dissipation holes 12 are opened at both ends of the printing roller body 1 at the position of the rotating shaft 11, and a filter screen 13 is arranged inside the heat dissipation holes 12, a heat dissipation component is arranged inside the printing roller body 1, and is used to cool the printing roller body 1, and an additional component is arranged outside the printing roller body 1, and is used to install a printing roller body 1 of other sizes.

[0022] In some embodiments, the heat dissipation component includes: a plurality of heat conducting plates 2 arranged on the inside of the printing roller body 1, the plurality of heat conducting plates 2 are distributed in a circular array on the inner wall of the printing roller body 1, heat dissipation plates 21 are respectively arranged at the bottom of the plurality of heat conducting plates 2, a plurality of fins 22 are arranged between two adjacent heat dissipation plates 21, the plurality of fins 22 are arranged in a wavy structure, and heat dissipation fans 23 are respectively arranged at both ends of the inside of the printing roller body 1, and the two heat dissipation fans 23 are symmetrically arranged.

[0023] When in use, the printing roller body 1 generates a large amount of heat, which is transferred to the heat sink 21 through the heat conduction plate 2. The heat sink 21 dissipates the heat into the air. At this time, the hot air is extracted through two heat dissipation fans 23, and the extracted hot air is discharged from the body through the heat dissipation holes 12. One of the two heat dissipation fans 23 draws air inwards, and the other sends air outwards, so that the air flow speed inside the printing roller body 1 becomes faster, and the cold air drawn in from the outside cools the heat sink 21, and the hot air inside is extracted and discharged from the body. The setting of the fins 22 can expand the heat dissipation area and increase the contact surface with the air, thereby improving the heat dissipation efficiency. The filter 13 can prevent external debris from entering and play a filtering role.

[0024] Among them, flow cavities 24 are opened inside several heat dissipation plates 21, and conduction grooves 25 are opened inside multiple fins 22. Two adjacent flow cavities 24 are connected to each other through the conduction grooves 25. One of the heat dissipation plates 21 is provided with a water inlet 26, which is connected to the flow cavity 24, and one of the heat dissipation plates 21 is provided with a return water port 27 at the end away from the water inlet 26.

[0025] By connecting the coolant delivery pipe to the water inlet 26, the coolant enters the flow cavity 24, and the coolant can absorb the heat of the heat sink 21. The coolant can flow through the interior of each flow cavity 24 through the conducting groove 25. When the coolant flows in the conducting groove 25, it also absorbs the heat of the fins 22. Finally, the coolant that has absorbed the heat is discharged back to the coolant tank through the return port 27, thereby forming a cycle, thereby enhancing the heat dissipation effect of the printing roller body 1.

[0026] In some embodiments, the additional components include: an auxiliary printing roller body 3 arranged outside the printing roller body 1, the auxiliary printing roller body 3 is composed of two semicircular plates 31, the two semicircular plates 31 are rotatably connected, and multiple support plates 32 are respectively arranged at the bottom of the two semicircular plates 31, and the bottom ends of the multiple support plates 32 located on the same semicircular plate 31 are fixedly connected to tube clamps 33, the two tube clamps 33 are located outside the rotating shaft 11, and two symmetrically arranged fixing grooves 34 are provided on the outside of the two rotating shafts 11, and fixing blocks 35 used in conjunction with the two fixing grooves 34 are fixedly connected on the inner walls on both sides of the two tube clamps 33, and connecting plates 36 are fixedly connected on both sides of the two tube clamps 33, and two fixing holes 37 are provided on the two connecting plates 36, and fastening bolts 38 are provided inside the two fixing holes 37.

[0027] When the size of the printing roller body 1 needs to be added, a suitable auxiliary printing roller body 3 is selected, the two semicircular plates 31 are opened, and the additional printing roller body 1 is clamped on the center closure. At this time, multiple support plates 32 push the two tube clamps 33 to merge and clamp the rotating shaft 11. When the two tube clamps 33 are merged, ensure that the fixing block 35 at the bottom is inserted into the corresponding fixing groove 34, so that when the rotating shaft 11 rotates, the auxiliary printing roller body 3 can be driven to rotate to avoid friction between the auxiliary printing roller body 3 and the printing roller body 1. At the same time, the two connecting plates 36 on both sides of the tube clamp 33 are also brought together, and the fastening bolts 38 are inserted into the fixing holes 37 and tightened to fix the two tube clamps 33 together, thereby completing the size addition.

[0028] In the above embodiments, the description of each embodiment has its own emphasis. For parts that are not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0029] The above is a detailed introduction to a chrome-plated printing roller with cooling protection provided in an embodiment of the present application. Specific examples are used in this article to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the technical solution and its core idea of ​​the present application.
