Description

Technical Field

[0001] This utility model specifically relates to a quick assembly and disassembly structure for a toner cartridge core. Background Technology

[0002] The drum core, also known as the photosensitive drum core, is a photoelectric conversion device formed by coating a conductive aluminum cylinder with OPC material. In the dark, it is an insulator, maintaining a certain static charge; when exposed to light of a specific wavelength, it becomes a conductor, releasing the charge through the aluminum substrate and forming an electrostatic latent image. To extend the drum core's lifespan, the printer needs regular cleaning and maintenance to avoid overheating from prolonged continuous use. When the drum core is damaged or reaches the end of its lifespan, it needs to be replaced promptly to ensure print quality and normal equipment operation. However, the assembly and disassembly of traditional drum cores often requires the removal of many related components due to the need for gear sets or belts, making the process very inconvenient, slow, and cumbersome. Therefore, improvements are necessary. Utility Model Content

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0019] like Figures 1 to 4 The present invention preferably provides a quick-installation and removal structure for a toner cartridge core, including a toner cartridge base 1. A drum core 11, a charging roller 12, a developing roller 13, and a gear set 14 are mounted on the drum base 1. A mounting bracket 2 for quick installation and removal of the drum core 11 is provided on the drum base 1. A separation cover 3 is provided on the drum base 1, connecting to and rotating synchronously with the drum core 11. The separation cover 3 is connected to the gear set 14. The drum core, charging roller, developing roller, and gear set are all existing technologies in existing toner cartridges. By providing a mounting bracket on the drum base, the drum core can be quickly installed and removed. During installation, the mounting bracket is opened, the drum core is placed, and the right end of the drum core is connected to the separation cover to complete the installation. When the toner cartridge is in use, the gear set is driven to rotate, which in turn drives the separation cover to rotate, thereby rotating the drum core. No gears are required on the drum core, and installation and removal do not require the removal of other related components; simply opening the mounting bracket allows the drum core to be connected or separated from the separation cover.

[0020] In this invention, the drum holder 1 is provided with a left vertical plate 41 and a right vertical plate 42 on its left and right sides, respectively. The left and right vertical plates correspond to the left and right ends of the drum core, respectively.

[0021] The mounting bracket 2 described in this utility model includes a beveled surface 21 on the left upright plate 41. A lower semi-circular groove 22 is provided on the beveled surface 21. A flip cover 23 is hinged to the lower side of the beveled surface 21. An upper semi-circular groove 24 is provided on the flip cover 23. The lower semi-circular groove 22 and the upper semi-circular groove 24 can form a complete circle for mounting the left end of the drum core 11. The beveled surface is a slanted cut surface, and the lower semi-circular groove is located on the beveled surface, which facilitates the insertion and removal of the left end of the drum core from the front or top of the drum. After the left end of the drum core is inserted, the flip cover can be flipped towards the beveled surface to close it, so that the left end of the drum core is located in the circular hole formed by the upper and lower semi-circular grooves.

[0022] The mounting bracket 2 described in this utility model also includes a sleeve 25 disposed on the right upright plate 42 and a through hole 26 disposed therein, wherein the right end of the drum core 11 is inserted into the through hole 26. After the left end of the drum core is installed, the drum core can also be moved laterally so that the right end of the drum core is aligned with the through hole and inserted. After insertion, the right end of the drum core can be connected to the separation cover.

[0023] In this invention, the separation cover 3 is located on the right upright plate 42, opposite to the drum core 11. Its position is aligned with the location of the gear set, ensuring that the gear set and the drum core are not in the same space and are not directly connected. Therefore, it is not necessary to disassemble the gear set when removing the drum core.

[0024] The separating cover 3 of this utility model includes an outer sleeve 31 sleeved outside the sleeve 25. A plurality of lubricating balls 32 are arranged annularly on the inner wall of the outer sleeve 31, conforming to the outer wall of the sleeve 25. A straight fitting 33 is provided at the center of the inner wall of the outer sleeve 31. A straight fitting groove 34 is provided at the right end of the drum core 11 and engages with the straight fitting 33. The drum core is installed and connected to the separating cover by inserting the straight fitting at the right end of the drum core into the straight fitting groove. When the outer sleeve rotates, the rotation of the straight fitting drives the drum core to rotate. Because the inner wall of the outer sleeve is provided with lubricating balls, the rotation of the outer sleeve is very smooth, indirectly making the rotation of the drum core equally smooth.

[0025] In this invention, a fixed gear 5 is fixedly mounted on the outer side of the outer sleeve 31 and meshes with the gear set 14. The fixed gear outside the outer sleeve can be in a state of meshing with the gear set for a long time, or the outer sleeve can be removed first when disassembling the drum core to make the drum core body easier to disassemble.

[0026] The foregoing has shown and described the basic principles and main features of this utility model, as well as its advantages. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
