Description

Technical Field

[0001] This utility model relates to the field of toner cartridge structure technology, specifically to a toner cartridge structure with an integrated end cap. Background Technology

[0002] Toner cartridges are an important component of laser printers. A toner cartridge includes a shell, a magnetic roller, a toner hopper inside the cartridge body, and a mixing rack inside the toner hopper. Currently, toner cartridges have protrusions on the end face of the shell for mounting gears, which increases the difficulty of shell processing. Existing toner cartridges have some shortcomings in use. In order to meet market needs, a toner cartridge structure with an integrated end cap is required.

[0003] The existing toner cartridge structure requires two separate steps during assembly, sequentially mounting the pinion and gear onto the corresponding protrusions. This carries the risk of gears detaching from the protrusions. The existing toner cartridge structure also suffers from low processing efficiency, increasing production costs and making assembly of the cartridge housing and body less smooth and inconvenient. Furthermore, the existing structure lacks adequate anti-static properties, making it prone to contamination of the photosensitive drum surface by the charging roller, compromising print quality. Finally, the existing toner cartridge structure is inconvenient for waste toner cleaning, leading to difficulties in the process. Utility Model Content

[0006] Preferably, the fixing frame and the drum housing are non-detachable, a shell is provided on one side of the drum body, a disassembly frame is provided on the surface of the shell, the disassembly frame and the shell are detachably connected, the photosensitive drum and the inner wall of the drum body are rotatably engaged, the charging roller and the inner wall of the drum body are rotatably engaged, and the surface of the charging roller is in contact with the surface of the photosensitive drum.

[0007] Preferably, the high-efficiency processing mechanism consists of a fixed cylinder, a snap-fit ​​bracket, fastening screws, and ball bearings. The fixed cylinder is installed on one side of the toner cartridge housing, and the snap-fit ​​bracket is installed on the surface of the toner cartridge body. The snap-fit ​​bracket and the surface of the fixed cylinder are snapped together. One end of the photosensitive drum extends to the outside of the fixed bracket and rotates with the inner wall of the fixed bracket.

[0008] Preferably, the inner wall of the fixing frame is provided with ball bearings, which rotate and engage with the inner wall of the fixing frame. The surface of the ball bearings contacts the surface of the photosensitive drum. The surface of the fixing frame is threaded with a fastening screw, one end of which passes through the fixing frame and is threadedly fastened to the surface of the toner cartridge body.

[0009] Preferably, the antistatic mechanism consists of a fixing groove, an antistatic block, a first antistatic film, and a second antistatic film. The surface of the charging roller is provided with a fixing groove, and an antistatic block for preventing static electricity between the charging roller and the photosensitive drum is installed inside the fixing groove.

[0010] Preferably, a second antistatic film is provided and installed between the charging roller and the photosensitive drum, the surface of the second antistatic film is fixed to the surface of the charging roller, a first antistatic film is installed on the surface of the second antistatic film, and the surface of the first antistatic film is fixed to the surface of the photosensitive drum.

[0011] Preferably, the waste powder cleaning mechanism consists of a sealing cover, a rubber gasket, a positioning slot, and a positioning block. The surface of the cleaning port is provided with a sealing cover, one end of which extends into the interior of the cleaning port, and positioning blocks are installed on the inner wall of the sealing cover.

[0012] Preferably, the surface of each cleaning port is provided with a positioning groove, the positioning groove and the surface of the positioning block are engaged with each other, and the surface of the sealing cover is covered with a rubber gasket for sealing, the surface of the rubber gasket is in contact with the inner wall of the cleaning port.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the integrated end cap toner drum structure not only saves production costs when using the toner drum structure, but also makes the assembly of the toner drum shell and the toner drum body smoother and easier to operate, and makes the toner drum body and the toner drum shell more secure, so that the toner drum structure can effectively prevent the charging roller from contaminating the surface of the photosensitive drum, ensuring the printing quality of the printer, and prevents static electricity accumulation during use, ensuring the normal operation of the toner drum, but also makes it convenient for users to clean the waste toner inside the toner drum body, avoiding the inconvenience of cleaning waste toner.

[0014] 1. With a high-efficiency processing mechanism, the drum housing drives the fixing frame to move automatically to one side of the drum body. The snap-fit ​​bracket on the surface of the drum body automatically snaps onto the surface of the fixing cylinder. Under the combined action of the fixing cylinder and the snap-fit ​​bracket, the drum housing is installed on the surface of the drum body, so that one end of the photosensitive drum moves to the outside of the fixing frame. When the photosensitive drum rotates inside the drum body, the ball rotates on the inner wall of the fixing frame. Under the action of the ball, the photosensitive drum rotates more smoothly inside the drum body. The user tightens the fastening screws on the surface of the fixing frame. Under the action of the fastening screws, the drum housing and the fixing frame are installed on the surface of the drum body. This realizes the function of high-efficiency processing of the drum structure, thereby saving production costs when using the drum structure, making the assembly of the drum housing and the drum body smoother and more convenient, and making the fixing between the drum body and the drum housing more secure.

[0015] 2. By incorporating an anti-static mechanism, static electricity can be generated between the charging roller and the photosensitive drum. The anti-static block inside the fixing groove eliminates this static electricity. The combined action of the first and second anti-static films prevents the charging roller from contaminating the surface of the photosensitive drum, ensuring print quality. By reducing contamination of the photosensitive drum surface by the charging roller, the drum can more stably adsorb toner, thereby reducing image defects during printing. This achieves the anti-static function of the drum structure, effectively preventing the charging roller from contaminating the surface of the photosensitive drum during use, ensuring the printer's print quality, and preventing static electricity accumulation during use, ensuring the normal operation of the drum.

[0016] 3. Equipped with a waste toner cleaning mechanism, the user pulls the sealing cover away from the inside of the cleaning port. This causes the sealing cover to move the positioning block away from the positioning slot, thus removing the sealing cover from the surface of the cleaning port. The sealing cover then moves the rubber gasket away from the inner wall of the cleaning port, allowing the waste toner inside the drum unit to be emptied through the cleaning port. After cleaning, the sealing cover automatically engages with the positioning block in the positioning slot, and the sealing cover moves the rubber gasket until it contacts the inner wall of the cleaning port. The rubber gasket seals the connection between the sealing cover and the cleaning port. The combined action of the positioning block and the positioning slot prevents the sealing cover from loosening, thus realizing the waste toner cleaning function of the drum unit. This makes it convenient for users to clean the waste toner inside the drum unit, avoiding inconvenience during cleaning. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0027] The structure of the integrated end cap toner cartridge provided by this utility model is as follows: Figures 1 to 4 As shown, the device includes a toner cartridge body 1, a toner hopper 101 mounted on the surface of the toner cartridge body 1, a side cover 104 mounted on the surface of the toner cartridge body 1, a toner cartridge housing 102 mounted on the surface of the toner cartridge body 1, a mounting bracket 103 mounted on the surface of the toner cartridge housing 102, the mounting bracket 103 and the toner cartridge housing 102 being non-detachably connected, an outer shell 105 mounted on one side of the toner cartridge body 1, a disassembly bracket 106 mounted on the surface of the outer shell 105, the disassembly bracket 106 and the outer shell 105 being detachably connected, a photosensitive drum 107 disposed inside the toner cartridge body 1, the photosensitive drum 107 rotating with the inner wall of the toner cartridge body 1, an assembly cover 108 mounted on the surface of the toner cartridge body 1, a charging roller 109 disposed inside the toner cartridge body 1, the charging roller 109 rotating with the inner wall of the toner cartridge body 1, the surface of the charging roller 109 contacting the surface of the photosensitive drum 107, and a cleaning port 110 opened on the surface of the toner cartridge housing 102.

[0028] Furthermore, such as Figure 2 and Figure 5 As shown, a high-efficiency processing mechanism 2 is provided on the surfaces of the toner cartridge body 1, the photosensitive drum 107, and the mounting bracket 103. The high-efficiency processing mechanism 2 consists of a fixing cylinder 21, a snap-fit ​​bracket 22, a fastening screw 23, and ball bearings 24. The fixing cylinder 21 is installed on one side of the surface of the toner cartridge housing 102, and the snap-fit ​​bracket 22 is installed on the surface of the toner cartridge body 1. The snap-fit ​​bracket 22 and the surface of the fixing cylinder 21 are snap-fitted together. One end of the photosensitive drum 107 extends to the outside of the mounting bracket 103 and rotates with the inner wall of the mounting bracket 103. Ball bearings 24 are provided on the inner wall of the mounting bracket 103. The ball bearings 24 rotate with the inner wall of the mounting bracket 103. The surface of the ball bearings 24 is in contact with the surface of the photosensitive drum 107. The surface of the mounting bracket 103 is threaded with a fastening screw 23. One end of the fastening screw 23 passes through the mounting bracket 103 and is threadedly fastened to the surface of the toner cartridge body 1.

[0029] During implementation, the snap-fit ​​bracket 22 on the surface of the drum body 1 automatically snaps onto the surface of the fixing cylinder 21. Under the combined action of the fixing cylinder 21 and the snap-fit ​​bracket 22, the drum housing 102 is installed on the surface of the drum body 1, causing one end of the photosensitive drum 107 to move to the outside of the fixing bracket 103. When the photosensitive drum 107 rotates inside the drum body 1, the ball bearing 24 rotates on the inner wall of the fixing bracket 103. Under the action of the ball bearing 24, the photosensitive drum 107 rotates more smoothly inside the drum body 1. The user tightens the fastening screw 23 on the surface of the fixing bracket 103. Under the action of the fastening screw 23, the drum housing 102 and the fixing bracket 103 are installed on the surface of the drum body 1, so as to realize the function of high-efficiency processing of the drum structure.

[0030] Furthermore, such as Figure 4 and Figure 7 As shown, the surfaces of the photosensitive drum 107 and the charging roller 109 are provided with an anti-static mechanism 3. The anti-static mechanism 3 consists of a fixing groove 31, an anti-static block 32, a first anti-static film 33, and a second anti-static film 34. The surface of the charging roller 109 is provided with a fixing groove 31. An anti-static block 32 for preventing static electricity between the charging roller 109 and the photosensitive drum 107 is installed inside the fixing groove 31. A second anti-static film 34 is provided and installed between the charging roller 109 and the photosensitive drum 107. The surface of the second anti-static film 34 is fixed to the surface of the charging roller 109. The surface of the second anti-static film 34 is provided with a first anti-static film 33. The surface of the first anti-static film 33 is fixed to the surface of the photosensitive drum 107.

[0031] During implementation, static electricity will be generated between the charging roller 109 and the photosensitive drum 107. The static electricity can be eliminated by the antistatic block 32 inside the fixing groove 31. The combined action of the first antistatic film 33 and the second antistatic film 34 can prevent the charging roller 109 from contaminating the surface of the photosensitive drum 107, thus ensuring print quality. By reducing the contamination of the surface of the photosensitive drum 107 by the charging roller 109, the drum can more stably adsorb toner, thereby reducing image defects during the printing process and realizing the antistatic function of the drum structure.

[0032] Furthermore, such as Figure 6 and Figure 8 As shown, a waste powder cleaning mechanism 4 is provided on the surface of the cleaning port 110. The waste powder cleaning mechanism 4 consists of a sealing cover 41, a rubber gasket 42, a positioning groove 43, and a positioning block 44. The surface of the cleaning port 110 is provided with a sealing cover 41, one end of which extends into the interior of the cleaning port 110. Positioning blocks 44 are installed on the inner wall of the sealing cover 41. Positioning grooves 43 are provided on the surface of the cleaning port 110. The surfaces of the positioning grooves 43 and the positioning blocks 44 engage with each other. The surface of the sealing cover 41 is covered with a rubber gasket 42 for sealing. The surface of the rubber gasket 42 is in contact with the inner wall of the cleaning port 110.

[0033] In practice, when a user needs to clean the waste toner inside the drum body 1, the user pulls the sealing cover 41 away from the inside of the cleaning port 110. At this time, the sealing cover 41 moves the positioning block 44 away from the inside of the positioning slot 43, thereby removing the sealing cover 41 from the surface of the cleaning port 110. The sealing cover 41 moves the rubber gasket 42 away from the inner wall of the cleaning port 110, and the waste toner inside the drum body 1 is poured out through the cleaning port 110. After the waste toner is cleaned, the user inserts the sealing cover 41 onto the surface of the cleaning port 110, so that the sealing cover 41 moves the positioning block 44 to automatically lock into the inside of the positioning slot 43. The sealing cover 41 moves the rubber gasket 42 to contact the inner wall of the cleaning port 110. Under the action of the rubber gasket 42, a seal is formed between the sealing cover 41 and the cleaning port 110. Under the joint action of the positioning block 44 and the positioning slot 43, the sealing cover 41 is prevented from loosening, so as to realize the function of cleaning waste toner in the drum structure.

[0034] Working principle: In use, first place the drum unit 1 in the designated position. Since the drum housing 102 and the mounting bracket 103 are integrally fixed, when the drum housing 102 is installed on the surface of the drum unit 1, it drives the mounting bracket 103 to automatically move to one side of the drum unit 1. The snap-fit ​​bracket 22 on the surface of the drum unit 1 automatically snaps onto the surface of the mounting cylinder 21. Under the combined action of the mounting cylinder 21 and the snap-fit ​​bracket 22, the drum housing 102 is installed on the surface of the drum unit 1, causing one end of the photosensitive drum 107 to move to the outside of the mounting bracket 103. When the photosensitive drum 107 is on the drum unit 1... During internal rotation, the ball bearing 24 rotates on the inner wall of the mounting bracket 103. Under the action of the ball bearing 24, the photosensitive drum 107 rotates more smoothly inside the drum body 1. The user tightens the fastening screw 23 on the surface of the mounting bracket 103. Under the action of the fastening screw 23, the drum housing 102 and the mounting bracket 103 are installed on the surface of the drum body 1, so as to realize the function of high-efficiency processing of the drum structure. This saves production costs when using the drum structure, makes the assembly of the drum housing 102 and the drum body 1 smoother and easier to operate, and makes the drum body 1 and the drum housing 102 more securely fixed.

[0035] Subsequently, when the charging roller 109 is working, it evenly spreads a layer of negative charge on the surface of the photosensitive drum 107. Some areas on the surface of the photosensitive drum 107 are irradiated and connected by the laser emitter, and charged with positive charge. Toner is applied to the developing roller, and the toner will adhere to the positively charged positions on the surface of the photosensitive drum 107. The negatively charged positions on the surface of the photosensitive drum 107 will be directly ignored by the toner, thereby printing on the surface of the paper.

[0036] Subsequently, static electricity will be generated between the charging roller 109 and the photosensitive drum 107. The static electricity can be eliminated by the anti-static block 32 inside the fixing groove 31. The combined action of the first anti-static film 33 and the second anti-static film 34 can prevent the charging roller 109 from contaminating the surface of the photosensitive drum 107, ensuring print quality. By reducing the contamination of the photosensitive drum 107 surface by the charging roller 109, the drum can more stably adsorb toner, thereby reducing image defects during the printing process. This achieves the anti-static function of the drum structure, effectively preventing the charging roller 109 from contaminating the surface of the photosensitive drum 107 during use, ensuring the print quality of the printer, and preventing the accumulation of static electricity during use, ensuring the normal operation of the drum.

[0037] Subsequently, when the user needs to clean the waste toner inside the toner cartridge body 1, the user pulls the sealing cover 41, causing the sealing cover 41 to move away from the inside of the cleaning port 110. At this time, the sealing cover 41 moves the positioning block 44 away from the inside of the positioning slot 43, thereby removing the sealing cover 41 from the surface of the cleaning port 110. The sealing cover 41 moves the rubber gasket 42 away from the inner wall of the cleaning port 110, allowing the waste toner inside the toner cartridge body 1 to be poured out through the cleaning port 110. After the waste toner is cleaned, the user inserts the sealing cover 41 back onto the surface of the cleaning port 110, causing the sealing cover 41 to move the positioning block 44 away from the inside of the cleaning port 110. 4. The automatic locking mechanism is inserted into the positioning slot 43. The sealing cover 41 moves the rubber gasket 42 to contact the inner wall of the cleaning port 110. Under the action of the rubber gasket 42, the sealing cover 41 and the cleaning port 110 are sealed. Under the joint action of the positioning block 44 and the positioning slot 43, the sealing cover 41 is prevented from loosening, so as to realize the function of cleaning waste powder of the toner cartridge structure. This makes it convenient for users to clean the waste powder inside the toner cartridge body 1 when using the toner cartridge structure, avoiding the inconvenience of operation when cleaning waste powder, and finally completing the use of the toner cartridge structure.
