Description

Technical Field

[0001] The utility model relates to the technical field of gravure printing plate rollers, in particular to an oxidation-resistant and corrosion-resistant gravure printing plate roller. Background Art

[0002] Gravure printing is a direct printing method that presses the ink contained in the gravure pits directly onto the substrate. The shades of the printed image are determined by the size and depth of the pits. A gravure roller is used in the gravure printing process.

[0003] In the patent application with the authorization publication number CN221113149U and the authorization publication date 2024-06-11, entitled "A wear-resistant gravure roller", when using the gravure roller, the mounting shafts on both sides are inserted into the mounting sleeves on both sides of the gravure roller, so that the mounting hole a is aligned with the mounting hole b, and then the mounting rod at the top of the mounting sleeve is passed through the mounting hole a and the mounting hole b, and the mounting rod is screwed to be threadedly connected with the nut at the bottom of the mounting sleeve, so that the gravure roller is fixedly mounted on the mounting shaft, and the gravure roller can be removed by only screwing the mounting rod out of the nut and pulling it out, which makes it easy to replace the gravure roller, thereby realizing fast printing of different patterns and improving work efficiency;

[0004] During the actual use of the above-mentioned device, after the mounting shaft is inserted into the mounting sleeve, the mounting hole a needs to be aligned with the mounting hole b before the connection is achieved. However, it is inconvenient for the staff to align the mounting hole a with the mounting hole b, which makes the installation more troublesome and reduces the installation efficiency. In addition, the gravure plate roller has the problem of reverse rotation, which affects the printing quality.

[0005] Therefore, we propose an oxidation-resistant and corrosion-resistant gravure printing plate roller to solve the above-mentioned problems. Utility Model Content

[0006] 1. Technical problems to be solved by the utility model:

[0007] The utility model aims to provide an oxidation-resistant and corrosion-resistant gravure printing plate roller to solve the problems in the current market raised by the above-mentioned background technology.

[0008] 2. Technical solution:

[0009] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an oxidation-resistant and corrosion-resistant gravure roller, comprising a gravure roller body, connecting sleeves are fixedly installed on both sides of the gravure roller body, and a mounting roller member is sleeved and installed at one end of the connecting sleeve away from the gravure roller body, and a fastener is installed between the mounting roller member and the connecting sleeve;

[0010] The mounting roller member includes an external shell, a first roller body and a second roller body, wherein the first roller body and the second roller body are respectively bearing-mounted on the left and right sides of the external shell, and a connecting column is fixed on the side of the first roller body close to the gravure plate roller body, and a positioning assembly is installed between the connecting column and the connecting sleeve, and a ratchet assembly is installed between the first roller body and the second roller body, and the ratchet assembly is located inside the external shell.

[0011] Furthermore, the surface of the gravure printing plate roller body is provided with an anti-oxidation layer and a corrosion-resistant layer in sequence from the inside to the outside, and the anti-oxidation layer is made of chromium oxide, and the corrosion-resistant layer is nickel-plated.

[0012] Through the above technical solution, the anti-oxidation and corrosion resistance can be improved through the anti-oxidation layer and the corrosion-resistant layer.

[0013] Furthermore, the positioning assembly includes a positioning block slidably installed inside the connecting column, a pressure spring is connected between the positioning block and the connecting column, and the end of the positioning block is fitted into the interior of the connecting sleeve, and the positioning block is opposite to the through opening, and the through opening is opened inside the connecting sleeve.

[0014] Through the above technical solution, under the action of the pressure spring, the positioning block can extend into the interior of the connecting sleeve, and then the positioning block is pressed through the through opening.

[0015] Furthermore, the side of the positioning block close to the connecting sleeve is designed to be inclined, and two positioning blocks are symmetrically arranged about the center of the connecting column.

[0016] Through the above technical solution, the positioning block can extend into the interior of the connecting sleeve without being blocked.

[0017] Furthermore, four fasteners are provided, and two fasteners form a group and are respectively installed on the left and right connecting sleeves.

[0018] The above technical solution can improve the installation firmness.

[0019] Furthermore, the ratchet assembly includes a ratchet fixedly mounted on the end of the second roller body and a pawl rotatably mounted on the first roller body, the ratchet and the pawl are meshed with each other, and a spring is attached to the side of the pawl, and the spring is fixed to the end of the first roller body.

[0020] The above technical solution can prevent the gravure printing plate roller from reversing and ensure the printing effect.

[0021] 3. Beneficial effects:

[0022] By adopting the technical solution provided by the utility model, compared with the prior art, the utility model anti-oxidation and corrosion-resistant gravure printing plate roller realizes pre-positioning during connection through the setting of the positioning component, improves the installation efficiency, and avoids the reverse rotation of the gravure printing plate roller, thereby ensuring the printing effect. The specific contents are as follows:

[0023] The two installation rollers are respectively sleeved inside the left and right connecting sleeves. During the sleeve process, the positioning block is retracted into the inside of the connecting column. Then, when it is installed to a suitable position, the positioning block is driven to extend into the inside of the connecting sleeve under the elastic action of the pressure spring to realize the connection and positioning between the connecting sleeve and the installation roller. Then, it is convenient to install and fix through fasteners to improve the installation efficiency. When disassembly is required, the fasteners are first removed, and then the positioning block is pressed through the opening to cause the positioning block to retract into the inside of the connecting column again. Then, the gravure printing plate roller body can be removed for replacement.

[0024] When the second roller body is rotated by force, the second roller body drives the first roller body to rotate by the cooperation of the ratchet, the pawl and the spring leaf, so that the gravure roller body can be driven to rotate synchronously through the connecting column and the connecting sleeve in turn. When the second roller body rotates in the opposite direction, the gravure roller body will not be driven to rotate in the opposite direction due to the cooperation of the ratchet, the pawl and the spring leaf, so that the printing effect can be guaranteed.

[0025] By providing the anti-oxidation layer and the anti-corrosion layer, the anti-oxidation performance and the anti-corrosion performance of the gravure printing plate roller body are improved, and the service life of the gravure printing plate roller body is extended.
