Description

Technical Field

[0001] The utility model relates to the technical field of magnetic roller polishing, and specifically relates to a magnetic roller polishing device. Background Technique

[0002] The printer magnetic roller is a component used to charge the toner and adsorb it on the surface. The magnetic roller of a printer is a key printing component. It makes the toner charged through friction with the powder outlet blade, so that the charged toner is adsorbed on the surface of the magnetic roller.

[0003] In a printer, the surface state of the magnetic roller directly affects the charging and transfer efficiency of the toner, and thus affects the printing quality. The smoothness of the magnetic roller surface has a significant impact on the printing quality. Through polishing, the minute defects and unevenness on the surface of the magnetic roller can be effectively removed, which is beneficial for the toner to be adsorbed on the magnetic roller more evenly. Through regular polishing maintenance, the surface integrity of the magnetic roller can be restored, further wear can be reduced, and its service life can be extended.

[0004] The existing Chinese patent (CN216000016U) discloses a new type of automatic polishing device for a printer magnetic roller, which includes a machine base and a protective cover with an open lower end arranged above the machine base. On the left and right of the machine base, there are respectively fixed jigs for fixing the magnetic roller. On the machine base, there is a moving device for driving the fixed jig to move horizontally left and right. Above the machine base, there is a polishing device for grinding and polishing the magnetic roller. On the machine base, there is a moving mechanism for driving the protective cover to move up and down. That is, when installing the magnetic roller, the protective cover is driven to move upward by the moving mechanism. At this time, the worker can install the magnetic roller in the fixed jig and drive the clamping to achieve fixation through the moving device. The fixed sleeve is detachably connected, and the fixed sleeve can be replaced according to the actual magnetic roller specifications to ensure the stability of the magnetic roller fixation, meeting the usage requirements.

[0005] In the above technical solution, the installation and fixation of the magnetic roller are achieved through the fixed sleeve. For magnetic rollers of different models, different fixed sleeves need to be replaced, which is inconvenient for the installation and disassembly of the magnetic roller and affects the polishing efficiency of magnetic rollers of different models.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0029] Please refer to Figure 1 , the present utility model provides a technical solution:

[0030] A magnetic roller polishing device, comprising: a polishing workbench 1 and a magnetic roller 9. On one side of the top surface of the polishing workbench 1, there is a fixed bearing seat 4, and on the other side, there is a sliding bearing seat 8. On one side of both the fixed bearing seat 4 and the sliding bearing seat 8, there is a three-jaw chuck 5. On one side of the fixed bearing seat 4, there is a driving motor 6, and between the three-jaw chucks 5, there is a magnetic roller 9. The two ends of the magnetic roller 9 are clamped and fixed by the three-jaw chuck 5, which is suitable for positioning when polishing magnetic rollers 9 with different diameters. By providing a fixed bearing seat 4 and a sliding bearing seat 8, the fixation of magnetic rollers 9 with different lengths is realized.

[0031] As Figure 4 shown, on one side of the top of the polishing workbench 1, there is a vertical plate 19. On one side of the vertical plate 19, there is a lead screw 11. Outside the lead screw 11, there is a lead screw nut 13. On one side of the outer wall of the lead screw nut 13, there is a cross bar 14. Inside the cross bar 14 and above the magnetic roller 9, there is a lifting bolt 15, and at the bottom end of the lifting bolt 15, there is a grinding head 16.

[0032] The grinding head 16 can be lifted by rotating the lifting bolt 15, which is suitable for grinding magnetic rollers 9 with different diameters. Thus, when polishing magnetic rollers 9 of different models, they can be quickly clamped and fixed without replacing the fixture, improving the polishing efficiency when polishing magnetic rollers of different models.

[0033] As Figure 2 shown, outside the top of the polishing workbench 1, there is a dust-proof cover 2, and on one side of the dust-proof cover 2, there is a hinged cover 3. The dust-proof cover 2 is used to protect the polishing workbench 1 and the user, preventing sundries from entering the polishing workbench 1 and also preventing the user from being injured by the rotating magnetic roller 9 or flying debris.

[0034] As Figure 4 shown, on one side of the bottom of the cross bar 14, there is a longitudinal bar 20. On one side of the bottom end of the longitudinal bar 20, there is a dust suction hood 10, and the dust suction hood 10 is located below the magnetic roller 9. There is an opening at the top of the dust suction hood 10, and the opening at the top of the dust suction hood 10 faces the grinding head 16. In the center of the bottom of the dust suction hood 10, there is a negative pressure hose 18, and the negative pressure hose 18 is used to connect to a vacuum cleaner. Through the transmission of the negative pressure suction generated by the vacuum cleaner through the negative pressure hose 18, a negative pressure dust suction cavity is formed above the dust suction hood 10, and the dust suction hood 10 can move synchronously with the grinding head 16 through the connection of the longitudinal bar 20. The dust suction hood 10 can immediately perform negative pressure adsorption on the polishing dust generated at the grinding head 16, avoiding the scattering of the dust.

[0035] At the connection part of the top of the polishing workbench 1 and the sliding bearing seat 8, a T-shaped groove is provided, and the sliding bearing seat 8 is fixed on the T-shaped groove through a T-shaped bolt. By connecting the sliding bearing seat 8 and the T-shaped groove 7 through a T-shaped bolt, the T-shaped bolt can be loosened or tightened, and the position of the sliding bearing seat 8 on the T-shaped groove 7 can be adjusted, so as to adjust the distance between the two three-jaw chucks 5, so as to be suitable for clamping magnetic rollers of different lengths.

[0036] As Figure 3 shown, bearing seats are provided at both ends of the lead screw 11, and the bearing seats make the rotation of the lead screw 11 smoother. The lead screw is drivingly connected to a servo motor 17, and one end of the output shaft of the servo motor 17 is fixedly connected to the lead screw 11. By driving the lead screw 11 to rotate by the servo motor 17, the rotational motion of the lead screw 11 is converted into a linear motion by a lead screw nut 13, so as to realize the translation of the grinding head 16 and facilitate the grinding of the outer wall of the magnetic roller 9.

[0037] As Figure 3 shown, a guide rod 12 is provided on one side of the vertical plate 19, and the guide rod 12 is slidably connected to the lead screw nut 13. A through hole is provided inside the lead screw nut 13 on the outside of the guide rod 12. The sliding of the lead screw nut 13 can be guided through the guide rod 12 to prevent the lead screw nut 13 from rotating along with the rotation of the lead screw 11.

[0038] The lifting bolt 15 is used to control the lifting of the grinding head 16. A threaded hole is provided inside the cross bar 14 for the lifting bolt 15, and the nut of the lifting bolt 15 is located above the cross bar 14. By loosening the nut, the screw of the lifting bolt 15 can be rotated, so as to realize the lifting of the grinding head 16, make the grinding head 16 contact with the outer wall of the magnetic roller, and thus perform grinding.

[0039] Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
