[0002] The printing roller is an important accessory of a rubber printing machine, and its main functions include transferring and coating ink to the printing plate. During the printing process, the printing roller and the plate cylinder work together to transfer the ink from the ink cartridge to the plate cylinder, and the image on the surface of the plate cylinder is then covered with ink. Subsequently, the ink is imprinted onto the paper or other printing substrates through the impression roller to form a complete printed matter. Secondly, during the printing process, the quality of the printing roller will directly affect the quality of the printed matter.

[0003] The following problems exist in the application of the existing printing rollers on the market:

[0004] 1. During the actual use of traditional printing rollers, usually multiple sets of fastening structures are used to install the printing rollers inside the frame. Once the printing roller structure needs to be removed, the operation of disassembling the fasteners is relatively complicated and time-consuming and laborious. Therefore, it is not convenient to disassemble during use.

[0005] 2. When most printing rollers are applied, the structures such as the cylinder on the side of the printing roller need to be installed with the mounting frame. However, due to frequent disassembly and assembly, the structures such as the cylinder will be worn to varying degrees. Since the structures such as the cylinder and the shaft body are integral structures, it is not convenient to repair them during application. Content of the Utility Model

[0027] To better understand the purpose, structure and function of the present utility model, the following further describes in detail a printing roller that is easy to disassemble according to the present utility model with reference to the accompanying drawings.

[0028] As Figures 1-4 shown, a printing roller that is easy to disassemble according to the present utility model includes a shaft body 1 and a roller body 2. The roller body 2 is provided outside the shaft body 1. A slot 4 is opened inside the shaft body 1, and a plug rod 3 is embedded inside the slot 4. An installation frame 11 is fixedly connected to the outside of the shaft body 1. A threaded seat 21 is connected to the side of the installation frame 11. A pressing screw rod 12 is threadedly connected inside the threaded seat 21. Due to the installation of the threaded seat 21, it is convenient for the pressing screw rod 12 to be threadedly connected to the installation frame 11. The pressing screw rod 12 penetrates through the plug rod 3, and the pressing screw rod 12 is threadedly connected inside the shaft body 1. By providing the plug rod 3, a positioning rod 5, an installation frame 11, a threaded seat 21, and a pressing screw rod 12 inside the shaft body 1, it is convenient to disassemble the printing roller.

[0029] A block 15 is provided on the outside of the plug rod 3. A turntable 16 is provided on the outside of the block 15. A cylinder 19 is provided on the other side of the turntable 16. A fixing ring 17 is fixedly connected to the outside of the cylinder 19. A pushing block 18 is provided on the outside of the fixing ring 17. The pushing blocks 18 are distributed in a circular form. By providing the block 15, the turntable 16, the fixing ring 17, and the pushing blocks 18 on the outside of the block 15, it is convenient to replace structures such as the cylinder 19, and the replacement is relatively simple.

[0030] A first threaded hole 9 and a second threaded hole 10 are opened inside the shaft body 1. A first through hole 7 and a second through hole 8 are opened inside the plug rod 3. The pressing screw rod 12 penetrates through the first through hole 7, and the pressing screw rod 12 is threadedly connected to the first threaded hole 9. Due to the provision of the first threaded hole 9 and the second threaded hole 10, the length of the plug rod 3 can be fixed according to actual conditions.

[0031] A positioning rod 5 is connected to the outside of the plug rod 3. A positioning groove 6 is opened inside the shaft body 1. The positioning rod 5 is embedded inside the positioning groove 6. By installing the positioning rod 5 and the positioning groove 6, the plug rod 3 will not be misaligned when installed inside the shaft body 1.

[0032] A threaded groove 14 is formed on the inner side of the block 15, and a threaded block 13 is provided on the side surface of the turntable 16. The threaded block 13 is threadedly connected to the inside of the threaded groove 14. Due to the provision of the threaded groove 14 and the threaded block 13, it is convenient to connect the block 15 and the column 19.

[0033] Two sets of clamping plates 20 are provided on the outside of the column 19. By providing the clamping plates 20, it is convenient to clamp structures such as the column 19 inside the frame.

[0034] The working principle of this easily detachable printing roller: When using this printing roller, first, the position of the printing roller needs to be moved. After moving to the designated position, it is first placed on the ground. Then, the staff installs the printing roller inside the frame by directly inserting the clamping plate 20 on the outside of the column 19 into the clamping seat. In this way, the printing roller can be used for printing work. Secondly, in order to facilitate the replacement of the damaged column 19 structure, a threaded block 13, a turntable 16, a fixing ring 17, and a pushing block 18 are provided on the outside of the block 15, and a fixing ring 17 and a pushing block 18 are provided on the side surface of the column 19. Secondly, a turntable 16 and a threaded seat 21 are provided on the outside of the fixing ring 17. When the structures such as the column 19 have been used for a long time and are severely worn, first rotate the turntable 16 in the reverse direction, and then push the pushing block 18 outside the turntable 16. In this way, the threaded rod on the side surface of the turntable 16 can be taken out from the inside of the threaded groove 14. Immediately afterwards, the staff takes out a new column 19 structure and reinstalls it, which is convenient for maintenance during application. Then it can be used continuously. When it is necessary to disassemble the printing roller, a quick-release structure is installed. By providing a plug rod 3, a positioning rod 5, a mounting bracket 11, a threaded seat 21, and a pressing screw 12 inside the shaft body 1, first reverse-rotate the pressing screw 12 inside the threaded seat 21 to take out the pressing screw 12 from the threaded seat 21. Then, reverse-pull the plug rod 3 inside the slot 4 to move the positioning rod 5 out of the positioning groove 6. In this way, it is convenient to disassemble the printing roller and the frame, and the disassembly operation is relatively simple during use. Secondly, a first through hole 7 and a second through hole 8 are formed on the outside of the plug rod 3, and a first threaded hole 9 and a second threaded hole 10 are formed inside the shaft body 1. In this way, the required length can be selected according to the actual situation, and the operation of installation and fixation is relatively simple.
