Description

Technical Field

[0001] The utility model relates to the technical field of developing rollers, in particular to an oblique cone type quick-installing developing roller. Background Art

[0002] The developing roller, also known as the fixing roller, is a key component of the toner drum of the laser printer imaging device. Its main function is to absorb the developer (such as toner) and transfer it to the surface of the photosensitive drum to form a visible image.

[0003] A Chinese patent discloses a developing roller (authorization publication number CN215376090U). This patented technology increases the wear resistance of the developing elastic layer by coating a layer of wear-resistant material with high strength and wear resistance on the surface of the developing elastic layer. This has good wear resistance and extends the service life of the developing roller. In addition, this wear-resistant material can also improve the adhesion to the rubber substrate, making it less likely for the wear-resistant material to fall off the surface of the developing elastic layer, thereby increasing adhesion stability.

[0004] In view of the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: when the existing developing roller is in use, as the printing operation continues, the surface of the developing roller will gradually wear out, and it needs to be replaced at this time. However, the developing rollers in the existing technology are mostly fixed by rigid mechanical connections, which causes the staff to spend more time on maintenance or replacement, affecting work efficiency. Utility Model Content

[0005] The technical problem to be solved by the present invention is that the prior art has the disadvantage that the developing roller is complicated to disassemble, so we propose an inclined cone type fast-installing developing roller.

[0006] In order to achieve the above-mentioned purpose, the present application adopts the following technical scheme: an oblique cone type quick-installation developing roller, including a toner cartridge main body, mounting chambers are installed on both sides of the interior of the toner cartridge main body, a mounting plate is installed on one side of the mounting chamber, a bearing is installed on one side of the mounting plate, an oblique cone type developing roller is installed inside the bearing, two clips are slidably connected inside the mounting chamber, the facing surfaces of the clips are fixedly connected with elastic springs, a slot is provided on the surface of the mounting plate, a sliding slot is provided at the front and rear ends of the mounting chamber, a sliding sleeve is fixedly connected at the front and rear ends of the mounting chamber, a sliding rod is slidably connected to the interior of the sliding groove and the sliding sleeve, and a push-pull plate is fixedly connected to the end of the sliding rod away from the mounting chamber.

[0007] Preferably, one end of the sliding sleeve close to the push-pull plate is fixedly connected to two elastic sheets, and one end of the elastic sheet away from the sliding sleeve is fixedly connected to the push-pull plate.

[0008] Preferably, a first sliding groove is provided at the top and bottom of the installation compartment, a first slider is fixedly connected to the top and bottom of the buckle, and the interior of the first sliding groove is slidably connected to the first slider.

[0009] Preferably, a second sliding groove is provided at the top and bottom ends of the sliding sleeve, a second sliding block is fixedly connected to the top and bottom ends of the sliding rod, and the interior of the second sliding groove is slidably connected to the second sliding block.

[0010] Preferably, a friction block is installed inside the slot.

[0011] Preferably, the surface of the buckle is provided with rounded corners.

[0012] The technical effects and advantages of this utility model are:

[0013] In the present invention, when the staff needs to install the oblique cone type developing roller, they align the card slot on the mounting plate with the card buckle and buckle it in. After buckling is completed, the elastic spring drives the card buckle to be firmly fixed in the card slot, so that the mounting bin and the mounting plate are fixed. When disassembly is required, the push-pull plate is pressed inward to make the sliding rod push the card buckle, so that it contacts and engages with the card slot, thereby achieving rapid disassembly of the oblique cone type developing roller. The quickly installable oblique cone type developing roller can provide the staff with a more convenient maintenance and replacement experience during use, and effectively improve work efficiency.

DETAILED DESCRIPTION

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show components related to the present invention.

[0022] Reference Figure 1 - Figure 4 As shown, the utility model provides a technical solution: an oblique cone type quick-installation developing roller, comprising a toner cartridge body 1, mounting chambers 2 are installed on both sides of the interior of the toner cartridge body 1, a mounting plate 3 is installed on one side of the mounting chamber 2, a bearing 4 is installed on one side of the mounting plate 3, an oblique cone type developing roller 5 is installed inside the bearing 4, two clips 6 are slidably connected to the interior of the mounting chamber 2, and elastic springs 7 are fixedly connected to the facing surfaces of the clips 6, a slot 8 is provided on the surface of the mounting plate 3, a sliding slot 9 is provided at the front and rear ends of the mounting chamber 2, a sliding sleeve 10 is fixedly connected to the front and rear ends of the mounting chamber 2, and a sliding rod 1 is slidably connected to the interior of the sliding slot 9 and the sliding sleeve 10 1. The end of the sliding rod 11 away from the mounting chamber 2 is fixedly connected with a push-pull plate 12. When the staff needs to install the oblique cone type developing roller 5, the slot 8 on the mounting plate 3 is aligned with the buckle 6 and buckled in. After buckling is completed, the elastic spring 7 drives the buckle 6 to be firmly fixed in the slot 8, so that the mounting chamber 2 and the mounting plate 3 are fixed. When disassembly is required, the push-pull plate 12 is pressed inward to make the sliding rod 11 push the buckle 6, so that it contacts and engages with the slot 8, thereby achieving quick disassembly of the oblique cone type developing roller 5. The oblique cone type developing roller 5 that can be quickly installed and disassembled can provide the staff with a more convenient maintenance and replacement experience during use, and effectively improve work efficiency.

[0023] Reference Figure 4 As shown, in this embodiment: one end of the sliding sleeve 10 close to the push-pull plate 12 is fixedly connected to two elastic sheets 13, and the end of the elastic sheet 13 away from the sliding sleeve 10 is fixedly connected to the push-pull plate 12. Through the arrangement of the elastic sheet 13, the push-pull plate 12 can automatically rebound by the elastic force of the elastic sheet 13 after the sliding rod 11 is pressed, thereby achieving automatic reset after the sliding rod 11 is pressed, which is convenient for next use.

[0024] Reference Figure 5As shown, in this embodiment: a first slide groove 14 is provided at the top and bottom ends inside the mounting bin 2, and a first slider 15 is fixedly connected to the top and bottom ends of the buckle 6. The inside of the first slide groove 14 is slidably connected to the first slider 15. Through the setting of the first slide groove 14 and the first slider 15, the buckle 6 can move more stably inside the first slide groove 14, thereby effectively improving the stability of the buckle 6 when it is engaged with the slot 8.

[0025] Reference Figure 6 As shown, in this embodiment: a second sliding groove 16 is provided at the top and bottom ends of the sliding sleeve 10, and the top and bottom ends of the sliding rod 11 are fixedly connected to a second slider 17, and the interior of the second sliding groove 16 is slidably connected to the second slider 17. Through the arrangement of the second sliding groove 16 and the second slider 17, the sliding rod 11 can be firmly limited when moving inside the sliding sleeve 10, thereby effectively preventing the sliding rod 11 from falling off when being pulled, causing inconvenience to the staff's operation.

[0026] Reference Figure 3 As shown, in this embodiment: a friction block 18 is installed inside the slot 8. Through the setting of the friction block 18, the buckle 6 can have a greater friction force with the surface of the slot 8 after being inserted into the slot 8, thereby significantly improving the installation stability of the bearing 4 and not easily falling off.

[0027] Reference Figure 3 As shown, in this embodiment: a rounded corner 19 is provided on the surface of the buckle 6. Through the setting of the rounded corner 19, when the buckle 6 is engaged with the slot 8, the slot 8 can slide along the edge of the rounded corner 19, thereby preventing the sharp corners from causing the buckle 6 to get stuck and effectively improving the engaging efficiency.

[0028] Working principle: When the staff needs to install the oblique cone type developing roller 5, the slot 8 on the mounting plate 3 is aligned with the buckle 6 and buckled in. After buckling, the elastic spring 7 drives the buckle 6 to be firmly fixed in the slot 8, so that the mounting chamber 2 and the mounting plate 3 are fixed. When it is necessary to disassemble, the push-pull plate 12 is pressed inward to make the sliding rod 11 push the buckle 6, so that it contacts and engages with the slot 8, thereby achieving the quick disassembly of the oblique cone type developing roller 5. The oblique cone type developing roller 5 that can be quickly installed can provide the staff with a more convenient maintenance and replacement experience during use, and effectively improve work efficiency. Through the setting of the elastic sheet 13, the push-pull plate 12 can automatically rebound by the elastic force of the elastic sheet 13 after the sliding rod 11 is pressed, thereby achieving automatic reset after the sliding rod 11 is pressed, which is convenient for next use. The setting of the first slide groove 14 and the first slider 15 can make the buckle 6 move more firmly inside the first slide groove 14, thereby effectively improving the stability of the buckle 6 when it is engaged with the slot 8. Through the setting of the second slide groove 16 and the second slider 17, the sliding rod 11 can be firmly limited when moving inside the sliding sleeve 10, thereby effectively preventing the sliding rod 11 from falling off when pulling, causing inconvenience to the staff's operation. Through the setting of the friction block 18, the buckle 6 can have a greater friction with the surface of the slot 8 after being engaged in the slot 8, thereby significantly improving the installation stability of the bearing 4 and not easily falling off. Through the setting of the rounded corner 19, the slot 8 can be made to slide along the edge of the rounded corner 19 when the buckle 6 is engaged with the slot 8, thereby preventing the sharp corners from causing the buckle 6 to get stuck and effectively improving the clamping efficiency.
