[0004] In view of the above situation and to overcome the defects of the prior art, this utility model provides a gravure printing plate roller mounting frame, which effectively solves the problem of inconvenience in quickly disassembling and assembling the printing plate roller.

[0005] To achieve the above functions, the technical solution adopted by this utility model is as follows: A gravure printing plate roller mounting frame includes a horizontally arranged cylindrical mounting frame with a cylindrical mounting cavity inside. A printing roller is horizontally inserted into the mounting cavity. A limiting block is fixedly provided on the outer side wall of the mounting frame. A limiting groove is opened on the side wall of the mounting frame. A rotating collar is rotatably sleeved on the outer surface of the mounting frame. A receiving groove and a docking groove are provided at equal intervals on the inner wall of the mounting frame. The docking groove penetrates the entire width of the rotating collar. The limiting block penetrates the limiting groove and is inserted into the receiving groove to achieve limiting. An abutment plate is slidably disposed inside the mounting cavity, and a spring is provided between the abutment plate and the inner wall of the mounting cavity to push the printing roller toward the limiting groove.

[0006] Preferably, the receiving groove and the docking groove are arranged adjacent to each other, and the docking groove and the limiting groove can be aligned by rotating the rotating collar.

[0007] Preferably, it also includes a fixed plate holder, which is disposed on the opposite side of the plate mounting frame and has an open structure at the top for accommodating the end of the plate roller.

[0008] Preferably, the printing roller has a groove on one side of the fixed printing plate frame, and the side wall of the fixed printing plate frame is threaded with a bolt, the end of which extends into the groove and slides in cooperation with the inner wall of the groove.

[0009] Preferably, the outer surface of the rotating collar is provided with anti-slip texture.

[0010] Compared with the prior art, the present invention, by adopting the above-described structure, achieves the following beneficial effects: By cooperating with the rotating collar, limiting groove, receiving groove, and docking groove, the printing roller can be quickly installed and disassembled, significantly improving the efficiency of printing plate changing. In addition, a fixed plate frame and threaded rod are added to cooperate with the sliding groove structure to further strengthen the installation stability of the printing roller and prevent shaking.

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0014] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The utility model will be further described in detail below with reference to the accompanying drawings.

[0015] like Figure 1-4As shown, the present invention proposes a gravure printing plate roller mounting frame, including a horizontally arranged cylindrical mounting frame 1, which has a cylindrical mounting cavity 2 inside. A printing roller 3 is horizontally inserted into the mounting cavity 2. A limiting block 4 is fixedly provided on the outer side wall of the mounting frame 1. A limiting groove 5 is opened on the side wall of the mounting frame 1. A rotating collar 6 is rotatably sleeved on the outer surface of the mounting frame 1. The outer surface of the rotating collar 6 is provided with anti-slip texture to facilitate rotation operation. The inner wall of the mounting frame 1 is provided with a receiving groove 7 and a docking groove 8 at equal intervals. The receiving groove 7 and the docking groove 8 are arranged adjacent to each other. By rotating the rotating collar 6, the docking groove 8 can be aligned with the limiting groove 5 to facilitate the disassembly of the printing roller 3. The docking groove 8 extends through the entire width of the rotating collar 6. The limiting block 4 passes through the limiting groove 5 and is inserted into the receiving groove 7 to achieve limiting. An abutment plate 9 is slidably arranged in the mounting cavity 2. A spring 10 is provided between the abutment plate 9 and the inner wall of the mounting cavity 2 to push the printing roller 3 toward the limiting groove 5.

[0016] like Figure 4 As shown, it also includes a fixed plate frame 11, which is located on the opposite side of the plate mounting frame 1. Its top is an open structure for accommodating the end of the plate roller 3. The plate roller 3 is provided with a groove 12 on the periphery of one end of the fixed plate frame 11. The side wall of the fixed plate frame 11 is threaded with a bolt 13, the end of which extends into the groove 12 and slides with the inner wall of the groove 12.

[0017] In practical use, insert the printing roller 3 horizontally into the mounting cavity 2 of the mounting frame 1, align the limiting block 4 on the printing roller 3 with the limiting groove 5 on the side wall of the mounting frame 1, rotate the rotating collar 6 to align the receiving groove 7 with the limiting block 4, and the spring 10 pushes the abutment plate 9 to press the printing roller 3 towards the limiting groove 5. The limiting block 4 is inserted into the receiving groove 7, completing the initial fixation. Place the other end of the printing roller 3 in the fixed mounting frame 11, tighten the bolt 13 so that its end extends into the sliding groove 12 of the printing roller 3 to achieve bidirectional fixation. Loosen the bolt 13 on the fixed mounting frame 11, push the printing roller 3 inward to compress the spring 10, rotate the rotating collar 6 to align the docking groove 8 with the limiting groove 5, and the printing roller 3 can be pulled out from the mounting cavity 2.
