Description

Technical Field

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

[0002] The plate roller is also called a steel roller. It is generally a solid roller with a shaft. It is often used for plate making. The surface of the roller is copper-plated, and the pattern is engraved by a gravure electronic engraving machine, and then a layer of chrome is plated. After it is completed, it is delivered to the printing factory and is often used for printing plastic packaging. The existing plate roller is generally an integrated structure. When it is used in different working conditions or embossing, it is often necessary to replace the entire plate roller. Disassembling the plate roller is troublesome, time-consuming and labor-intensive, affecting work efficiency. In addition, frequent replacement of the plate roller will damage the installation part of the roller shaft and affect its service life.

[0003] A combined gravure printing plate roller mentioned in an existing Chinese public patent (authorization announcement number: CN217293866U) includes a support column and a plate roller, a limit plate is fixedly arranged between the support columns, a connecting assembly is arranged on the outer surface of the plate roller and the support column, a cleaning assembly is arranged on the outer surface of the support column, the connecting assembly includes a semicircular cylinder and a circular block, the semicircular cylinder is rotatably connected to one side of the opposite surface of the support column, the utility model makes the circular block on one side of the plate roller fit with the connecting groove provided inside the semicircular cylinder, so that the socket provided on the semicircular cylinder and the socket provided on the circular block are aligned, and the bolt is inserted into the socket, and the nut is sleeved on the bolt, so as to combine and connect the plate roller and the support column.

[0004] When printing printed materials, the existing combined plate roller needs to transfer ink or paint from the ink tray or ink pool to the printing plate through the plate roller, and evenly apply the ink or paint on the surface of the printing plate, which makes it easy for the plate roller to be contaminated with various inks and paints. When cleaning the plate roller, the entire plate roller needs to be removed from the roller shaft for cleaning, which makes cleaning and replacement of the plate roller inconvenient. Utility Model Content

[0005] The purpose of the present application is to solve the problem that it is inconvenient to clean and replace the existing plate roller, and to provide a combined plate roller.

[0006] In order to achieve the above-mentioned purpose, this application specifically adopts the following technical solutions:

[0007] A combined plate roller comprises a roller shaft, a roller body is arranged on the roller shaft, a surface plate is arranged on the roller body, an annular base is fixedly connected to the roller body, the annular base is adapted to the surface plate, and a mounting structure is arranged between the roller body and the roller shaft.

[0008] By adopting the above technical solution, after using the plate roller to print the printed matter, the surface plate can be removed from the roller body through the installation structure, and there is no need to remove the roller body from the roller shaft. This facilitates the cleaning and replacement of the device after use, and also speeds up and improves the printing efficiency by quickly replacing the surface plate.

[0009] Furthermore, the mounting structure includes a T-shaped groove opened on the roller body, a T-shaped plate is fixedly connected to the surface plate, and the T-shaped groove is adapted to the T-shaped plate.

[0010] By adopting the above technical solution, the T-shaped groove is adapted to the T-shaped plate, so that the installation of the surface plate on the roller body is more stable.

[0011] Furthermore, a fixing column is fixedly connected to the roller body, a sliding block is slidably connected to the fixing column, a limiting bolt is fixedly connected to the sliding block, and a rotating plate is threadedly connected to the limiting bolt.

[0012] By adopting the above technical solution, the rotating plate is rotated to move it away from the sliding block, and then the rotating plate is pushed to drive the sliding block away from the T-shaped plate, and then the surface plate is pulled out along the T-shaped groove. By cleaning and replacing the surface plate, the plate roller is replaced for cleaning, which facilitates the disassembly of the plate roller.

[0013] Furthermore, a return spring is sleeved on the fixed column, and two ends of the return spring are fixedly connected to the sliding block and the roller body respectively.

[0014] By adopting the above technical solution, the reset spring is reset to push the sliding block to move toward the surface plate, so the position of the rotating plate when limited can be easily adjusted.

[0015] Furthermore, a side plate is fixedly connected to the roller body, a mounting groove is opened between the side plate and the roller shaft, a mounting bolt is arranged in the mounting groove, and a nut is threadedly connected to the mounting bolt.

[0016] By adopting the above technical solution, the mounting bolts are passed through the side plates and the roller shaft and fixed by nuts.

[0018] By adopting the above technical solution, the semicircular limiting groove is close to the position of the semicircular limiting block, and the semicircular limiting block enters the semicircular limiting groove to limit the limiting plate, so that the roller body and the roller shaft are in a pre-fixed state.

[0019] Furthermore, a limit spring is sleeved on the sliding column, and two ends of the limit spring are fixedly connected to the semicircular limit block and the roller body respectively.

[0020] By adopting the above technical solution, the limiting spring resets and pushes the semicircular limiting block into the semicircular limiting groove, thereby enhancing the limiting effect between the roller body and the roller shaft.

[0021] Furthermore, a trapezoidal plate is fixedly connected to the roller body, and the trapezoidal plate is adapted to the surface plate.

[0022] By adopting the above technical solution, the trapezoidal plate corresponds to the surface plate, so that when the surface plate contacts with paint and ink, it is difficult for them to penetrate through the gap between the surface plate and the roller body, thereby reducing the difficulty of cleaning.

[0023] In summary, the present application includes at least one of the following beneficial effects:

[0024] 1. In the present application, after the plate roller is used, the rotating plate is first rotated to move it away from the sliding block, and then the rotating plate is pushed to drive the sliding block away from the T-shaped plate, and then the surface plate is pulled out along the T-shaped groove, and the surface plate is cleaned and replaced instead of being cleaned by the plate roller. When installing the surface plate, the rotating plate is pushed away from the T-shaped plate, and then the surface plate is inserted into it along the T-shaped plate so that the surface plate is attached to the surface of the roller body. At this time, the rotating plate is released to reset the reset spring, and the sliding block is pushed toward the surface plate, and then the rotating plate is rotated to limit the position between the surface plate and the roller body. This pre-fixes the surface plate during the installation process, making its installation more convenient, facilitating the replacement and cleaning of the device after printing, and improving printing efficiency.

[0025] 2. In the present application, when a roller body is needed, the roller body is first slid along the roller shaft so that the limit plate moves into the limit plate groove. At this time, as the limit plate moves, the semicircular limit groove approaches the position of the semicircular limit block, so that the limit spring is reset and pushed, and the semicircular limit block enters the semicircular limit groove to limit the limit plate, so that the roller body and the roller shaft are in a pre-fixed state. Then, the mounting bolts are passed through the side plates and the roller shaft and fixed with nuts, so that the position of the roller body on the roller shaft can be limited during the installation process, making its installation more convenient and accurate, thereby reducing the difficulty of manual installation.

[0036] After using the plate roller to print the printed matter, the surface plate 3 can be removed from the roller body 2 through the installation structure, and there is no need to remove the roller body 2 from the roller shaft 1. This facilitates the cleaning and replacement of the device after use, and also speeds up and improves the printing efficiency by quickly replacing the surface plate 3.

[0037] Reference Figure 2 and Figure 4 The mounting structure includes a T-shaped slot 15 opened on the roller body 2, a T-shaped plate 13 is fixedly connected to the surface plate 3, and the T-shaped slot 15 is adapted to the T-shaped plate 13. A fixed column 10 is fixedly connected to the roller body 2, a sliding block 12 is slidably connected to the fixed column 10, a limit bolt 14 is fixedly connected to the sliding block 12, and a rotating plate 6 is threadedly connected to the limit bolt 14. A reset spring 11 is sleeved on the fixed column 10, and the two ends of the reset spring 11 are fixedly connected to the sliding block 12 and the roller body 2 respectively.

[0038] After the plate roller is used, first rotate the rotating plate 6 to move it away from the sliding block 12, and then push the rotating plate 6 to drive the sliding block 12 away from the T-shaped plate 13, and then pull out the surface plate 3 along the T-shaped groove 15, and clean and replace the surface plate 3 to clean the plate roller. When installing the surface plate 3, push the rotating plate 6 away from the T-shaped plate 13, and then insert the surface plate 3 into it along the T-shaped plate 13, so that the surface plate 3 adheres to the surface of the roller body 2. At this time, release the rotating plate 6 to reset the reset spring 11, push the sliding block 12 to move toward the surface plate 3, and then rotate the rotating plate 6 to limit the position between the surface plate 3 and the roller body 2. This allows the surface plate 3 to be pre-fixed during the installation process, which makes its installation more convenient, facilitates the replacement and cleaning of the device after printing, and improves printing efficiency.

[0039] Reference Figure 3 and Figure 5 The roller body 2 is fixedly connected with a side plate 7, a mounting groove is provided between the side plate 7 and the roller shaft 1, a mounting bolt 8 is provided in the mounting groove, and a nut 9 is threadedly connected to the mounting bolt 8.

Then, the mounting bolts 8 are passed through the side plates 7 and the roller shaft 1 and fixed by nuts 9, so that the position of the roller body 2 on the roller shaft 1 can be limited during the installation of the roller body 2, making its installation more convenient and accurate, thereby reducing the difficulty of manual installation.

[0041] Reference Figure 2 A trapezoidal plate is fixedly connected to the roller body 2, and the trapezoidal plate is adapted to the surface plate 3.

[0042] By making the trapezoidal plate correspond to the surface plate 3, when the surface plate 3 contacts with paint and ink, it is difficult for them to penetrate through the gap between the surface plate 3 and the roller body 2, thereby reducing the difficulty of cleaning.

[0043] Working principle: after the plate roller is used, first rotate the rotating plate 6 to move it away from the sliding block 12, then push the rotating plate 6 to drive the sliding block 12 away from the T-shaped plate 13, and then pull out the surface plate 3 along the T-shaped groove 15, and clean and replace the surface plate 3 to replace the plate roller. When installing the surface plate 3, push the rotating plate 6 away from the T-shaped plate 13, and then insert the surface plate 3 into it along the T-shaped plate 13, so that the surface plate 3 adheres to the surface of the roller body 2. At this time, release the rotating plate 6 to reset the reset spring 11, push the sliding block 12 to move toward the surface plate 3, and then rotate the rotating plate 6 to limit the surface plate 3 and the roller body 2. This makes the surface plate 3 pre-fixed during the installation process, making its installation more convenient and facilitating the replacement and cleaning of the device after printing.

[0044] When the roller body 2 is needed, the roller body 2 is first slid along the roller shaft 1 so that the limit plate 16 moves into the limit plate 16 groove. At this time, with the movement of the limit plate 16, the semicircular limit groove approaches the position of the semicircular limit block 19, so that the limit spring 18 is reset and pushed, and the semicircular limit block 19 enters the semicircular limit groove to limit the limit plate 16, so that the roller body 2 and the roller shaft 1 are in a pre-fixed state. Then, the mounting bolts 8 are passed through the side plates 7 and the roller shaft 1 and fixed by nuts 9, so that the position of the roller body 2 on the roller shaft 1 can be limited during the installation of the roller body 2, making its installation more convenient and accurate.
