Description

Technical Field

[0001] The utility model relates to the technical field of frosting rollers, in particular to a frosting roller for a UV printing machine. Background Art

[0002] The frosting roller of a printing machine is mainly used to perform frosting treatment on the surface of printing materials during the printing process to increase the texture and aesthetics of printed products. Through the action of the frosting roller, the gloss on the surface of the material can be removed to create a matte or semi-matte effect, and sometimes it is also used to improve the adhesion and coverage of ink.

[0003] Common frosting rollers for printing machines generally include a roller body, a rubber outer cylinder and a connection structure. The roller body supports the weight of the entire roller and keeps it running in a straight line. The rubber outer cylinder provides the necessary elasticity and friction coefficient, which helps the effective contact between the frosting roller and the printing material.

[0004] The rubber outer cylinder will inevitably wear after long-term use. However, since the rubber outer cylinder is generally pasted on the surface of the roller body by special industrial glue or adhesive, when replacing the rubber outer cylinder, the rubber outer cylinder needs to be damaged to be taken out from the surface of the roller body, resulting in the inability to replace the rubber outer cylinder completely, and the recovered rubber outer cylinder is also in a damaged state, affecting the recovery quality of the rubber outer cylinder. Content of the Utility Model

[0005] (I) Technical Problems to be Solved

[0006] In view of the deficiencies of the prior art, the utility model provides a frosting roller for a UV printing machine to solve the problem that when replacing the rubber outer cylinder, the rubber outer cylinder needs to be damaged to be taken out from the surface of the roller body, resulting in the inability to replace the rubber outer cylinder completely, and the recovered rubber outer cylinder is also in a damaged state, affecting the recovery quality of the rubber outer cylinder as mentioned in the above background art.

[0007] (II) Technical Solutions

[0008] To achieve the above object, the utility model provides the following technical solutions: A frosting roller for a UV printing machine, comprising:

[0009] A roller body, with a rubber outer cylinder sleeved on the surface of the roller body;

[0010] Connecting columns, arranged at both ends of the roller body, and limiting rings are arranged on both sides of the surface of the roller body;

[0011] Mounting plates, arranged at both ends of the roller body, positioning rings are arranged on the inner sides of the mounting plates, and the positioning rings are all sleeved on the surface of the roller body;

[0012] The threaded rod is arranged on the surface of the mounting plate, and the threaded rods are evenly distributed on the surface of the mounting plate.

[0013] Preferably, mounting rods are evenly installed on the surface of the mounting plate, and the inner ends of the mounting rods are connected to the surface of the positioning ring. The mounting rods are used to connect the positioning ring to the mounting plate, so that the positioning ring can move along with the mounting plate.

[0014] Preferably, sliders are evenly installed on the inner wall of the limiting ring, and chutes are opened at corresponding positions on the upper surface of the roller body. When the sliders are inserted into the chutes, the limiting ring can be positioned, enabling the limiting ring to move in a straight line.

[0015] Preferably, limiting grooves are evenly formed on the surface of the roller body, and limiting strips are installed at corresponding positions on the inner wall of the rubber outer cylinder.

[0016] Preferably, the inner cavities of the chutes communicate with the inner cavities of the limiting grooves, and the chutes penetrate through both sides of the roller body. When installing the rubber outer cylinder, the rubber outer cylinder can be sleeved on the surface of the roller body by simply inserting the limiting strips into the limiting grooves through the chutes.

[0017] Preferably, threaded holes are formed at corresponding positions on both sides of the roller body, and the threaded rods penetrate through the mounting plate and are screwed into the inner cavities of the threaded holes. Screwing the threaded rods into the threaded holes can drive the mounting plate to move, thereby driving the positioning ring to squeeze the limiting ring, and further squeezing both sides of the rubber outer cylinder to position the rubber outer cylinder.

[0018] Beneficial effects

[0019] Compared with the prior art, the present utility model provides a frosted roller for a UV printing machine, which has the following

[0020] Beneficial effects:

[0021] For this frosted roller for a UV printing machine, the threaded rod can squeeze the mounting plate, thereby driving the positioning ring to squeeze the limiting ring, and further squeezing both sides of the rubber outer cylinder to position the rubber outer cylinder. When replacing the rubber outer cylinder, by removing the threaded rod, the mounting plate can be pulled out from the surface of the roller body, and then the limiting ring can be disassembled, so that the rubber outer cylinder can be pulled out from both sides of the roller body, avoiding damage to the rubber outer cylinder and enabling the rubber outer cylinder to be replaced completely, improving the recycling quality of the rubber outer cylinder.
