Description

Technical Field

[0001] The present invention belongs to the technical field of toner cartridges, and particularly relates to a printer toner cartridge that avoids toner sticking. Background Art

[0002] A toner cartridge, also known as a photosensitive drum, generally consists of a basic substrate made of aluminum and a photosensitive material coated on the substrate. The toner cartridge not only determines the quality of printing but also determines the amount of money the user needs to spend during use. In a laser printer, more than 70% of the imaging components are concentrated in the toner cartridge, and the printing quality is actually largely determined by the toner cartridge. Selenium in the toner cartridge is a non-metallic chemical element and can be used as a photosensitive material, a catalyst in the electrolytic manganese industry, an essential nutrient element for animals, and a beneficial nutrient element for plants, etc.

[0003] When a traditional toner cartridge is in use:

[0004] 1. Since the toner cartridge is difficult to disassemble, the powder outlet blade inside it is difficult to clean. As a result, after long-term use, the powder outlet blade is contaminated with toner, and a large amount of toner accumulates and condenses into lumps on the surface of the powder outlet blade. When printing, there are toner imprints remaining on the printed paper surface, affecting the printing quality. Seriously, it can cause the printer to be unusable.

[0005] 2. Since two internal components are connected by a spring and it is difficult to take out the spring alone, when disassembling the two components inside the toner cartridge, the spring is likely to fall off or be deformed due to the pulling force, making it unable to be used normally again, causing inconvenience in disassembly.

[0006] 3. Since it is fixed with bolts and difficult to open without tools, due to the limitation of tools, the user cannot clean its interior for a long time, resulting in the accumulation of internal toner, damaging the internal components, and making the toner cartridge unusable. Summary of the Invention

[0007] Aiming at the deficiencies of the existing technology, the purpose of the present invention is to provide a printer toner cartridge that avoids toner sticking, and solves the problems that the toner cartridge is difficult to disassemble and the powder outlet blade inside it is difficult to clean.

[0008] To achieve the above object, the present invention provides the following technical solution: A printer toner cartridge that avoids toner sticking, comprising a placement box and two cleaning plates. A seal is fixedly installed on the top of the placement box. A magnetic roller and a powder outlet blade are fixedly connected inside the placement box. Baffles are fixedly installed on both sides of the placement box. Clamping plates are fixedly installed on the tops of the two cleaning plates. Sliders are rotatably connected to the tops of the two clamping plates. A first spring is fixedly installed at one end of the two clamping plates close to each other. Slide rails are fixedly installed on both sides of the slider, and a rotating bead is fixedly connected to one side of the slider. A connecting ring is rotatably installed on the surface of the rotating bead. A sliding rod is fixedly connected to the bottom end of the connecting ring. A motor is slidably installed at the bottom end of the sliding rod. A threaded rod is fixedly connected to the top of the motor. A groove block is fixedly installed on one side of the baffle. A plug is slidably installed on one side of the groove block. A threaded block is threadedly installed on the side of the plug away from the groove block. A second spring is fixedly connected to one side of the threaded block. A pulling block is slidably installed inside the plug. A pulling rope is fixedly connected to the bottom end of the pulling block. A clamping block is fixedly installed at one end of the pulling rope away from the pulling block, and a third spring is sleeved on the surface of the pulling rope. A bolt is threadedly installed on one side of the placement box. A plug rod is inserted into the bolt. An auxiliary block is fixedly connected to one side of the plug rod.

[0009] Preferably, the sides of the two cleaning plates close to each other are both slidably installed on the surface of the powder outlet blade. The size specifications of the surfaces of the two cleaning rods are adapted to the size specifications of the surface of the powder outlet blade. The bottom end of the slide rail is fixedly connected to the top of the powder outlet blade.

[0010] By adopting the above technical solution, the advantage is that the structure of the device can clean the surface of the powder outlet blade, avoiding the powder outlet blade being contaminated with toner after long-term use, and a large amount of toner accumulating and condensing into blocks on the surface of the powder outlet blade, resulting in toner imprints remaining on the printed paper during printing and affecting the printing quality.

[0011] Preferably, the two clamping plates are rotatably installed with each other. The cross-section of the slider is in a "U" shape, and the inner wall of the slider is rotatably installed at the connection with the two clamping plates.

[0012] By adopting the above technical solution, the advantage is that the elastic force of the first spring is used to make the two clamping plates fit the surface of the powder outlet blade, avoiding the upper part of the powder outlet blade being wide and the lower part being narrow, and the cleaning plate not being able to fit the two sides of the powder outlet blade when moving up and down, resulting in incomplete cleaning by the cleaning plate.

[0013] Preferably, the inner wall of the connecting ring is threadedly installed on the surface of the threaded rod. The surface of the motor is fixedly connected to the inside of the powder outlet blade. The center of the motor and the center of the threaded rod are on the same vertical line. The size specifications of one side of the threaded rod are adapted to the size specifications of one side of the slide rail.

[0014] By adopting the above technical solution, the advantage lies in the structure that enables the cleaning plate to move slowly up and down by using the threaded rod, avoiding the situation that the cleaning plate moves too fast, causing scratches on the surface of the powder outlet knife or damaging the internal parts of the machine body, which affects the use of the toner cartridge.

[0015] Preferably, the size specifications of the surface of the insertion block are adapted to the size specifications of the inner wall of the groove block. The surface of the clamping block is clamped inside the groove block. The cross-section of the clamping block is in a triangular structure. The bottom end of the clamping block is rotatably installed on the surface of the insertion block, and there are at least two clamping blocks. One end of the third spring is fixedly installed on one side of the clamping block, and the end of the third spring away from the clamping block is fixedly installed on the inner wall of the insertion block.

[0016] By adopting the above technical solution, the advantage lies in the structure that enables the spring to be disengaged from the groove block by sliding the slider, avoiding the situation that the spring falls off when disassembling the two components, or being deformed due to the pulling force, resulting in the spring being unable to be used normally again, causing inconvenience in disassembly.

[0017] Preferably, the center of the threaded block and the center of the second spring are on the same straight line.

[0018] By adopting the above technical solution, the advantage lies in the structure that the second spring can be disassembled by rotating the threaded block, avoiding the difficulty in replacing the second spring when it is damaged.

[0019] Preferably, the surface of the pull rope is slidably installed inside the insertion block, and there are at least two pull ropes. Pull grooves are formed on the surface of the pull block.

[0020] By adopting the above technical solution, the advantage lies in that lifting the pull block can release the fixation of the clamping block on the slider, making the installation and disassembly more convenient.

[0021] Preferably, the surface of the insertion rod is slidably installed inside the placement box. The cross-section of the insertion rod is in a "Z" - shaped structure. There are at least two insertion rods. The auxiliary block is a rubber block, and the surface of the auxiliary block is clamped inside the placement box.

[0022] By adopting the above technical solution, the advantage lies in that the bolt can be rotated without tools, avoiding the situation that due to the limitation of tools, the baffles on both sides of the placement box are difficult to disassemble, and the user cannot clean its interior for a long time, resulting in the accumulation of internal toner.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] 1. The cleaning plate at the bottom of the clamp plate slides on both sides of the powder knife by sliding the slider in the slide rail to clean the carbon powder on the surface of the powder knife. The device can be used to clean the surface of the powder knife to avoid the powder knife being stained with carbon powder after long-term use. A large amount of carbon powder accumulates on the surface of the powder knife and condenses into blocks, so that when printing, there are traces of carbon powder on the printed paper, which affects the printing quality. The first spring squeezes the clamp plates on both sides to make the bottom of the clamp plate fit with the surface of the powder knife, and the elastic force of the first spring is used to hold the two clamp plates and the powder knife together. The surface of the knife fits together to avoid the powder knife being wide at the top and narrow at the bottom. The cleaning plate cannot fit together with the two sides of the powder knife when moving up and down, resulting in incomplete cleaning of the cleaning plate. The motor controls the slide rod to rotate so that the connecting ring at its upper end rotates on the surface of the threaded rod and moves up and down. The rotating ball changes position following the movement of the connecting ring, causing the slider connected to the cleaning plate to move up and down. The threaded rod is used to make the cleaning plate move up and down slowly, thereby preventing the cleaning plate from moving too fast, causing scratches on the surface of the powder knife, or damage to the internal parts of the machine body, affecting the use of the toner cartridge.

[0025] 2. The second spring is connected to the slot block by an inserted block. When the two components are separated, the inserted block is taken out of the slot block. The two clamping blocks are clamped in the slot block with the help of the elastic force of the third spring, thereby fixing the inserted block on the slot block. The spring can be separated from the structure of the slot block by using a sliding slider, so as to avoid the spring falling off when the two components are disassembled, or the spring being deformed due to the pulling force, resulting in the spring being unable to be used normally again, causing inconvenience in disassembly. When the second spring is damaged and cannot be used, the second spring can be taken out from the inside of the inserted block by rotating the threaded block and replaced with a new spring. The structure that the second spring can be disassembled by rotating the threaded block can avoid difficulty in replacing the second spring when it is damaged. The tool is clamped in the pull groove on the pull block, and the pull block is lifted upward, so that the pull rope at the bottom of the pull block pulls the clamping block, so that the clamping block is separated from the slot block and retracted into the inserted block. The clamping block can be released from the fixation of the slider by lifting the pull block, making it more convenient during installation and disassembly.

[0026] 3. Install it into the placement box by rotating the set bolts to fix it with the baffle, insert the sliding rod into the placement box, fix the bolts, and the rubber auxiliary block is stuck inside the placement box to prevent the sliding rod from being vibrated and separated from the placement box. The bolts can be rotated without tools, avoiding the difficulty of removing the baffles on both sides of the placement box due to the limitation of tools, and the user cannot clean the inside for a long time, resulting in the accumulation of internal carbon powder.

Specific embodiments

[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of 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.

[0035] Embodiment 1:

[0036] Please refer to Figures 1-6, the present invention provides a technical solution: a printer toner cartridge that avoids toner sticking, including a placement box 1 and two cleaning plates 6. A seal 2 is fixedly installed on the top of the placement box 1. A magnetic roller 3 and a powder outlet blade 4 are fixedly connected inside the placement box 1. Baffles 5 are fixedly installed on both sides of the placement box 1. Clamping plates 7 are fixedly installed on the tops of the two cleaning plates 6. A slider 8 is rotatably connected to the tops of the two clamping plates 7. A first spring 11 is fixedly installed at one end of the two clamping plates 7 close to each other. Slide rails 9 are fixedly installed on both sides of the slider 8. And a rotating bead 10 is fixedly connected to one side of the slider 8. A connecting ring 12 is rotatably installed on the surface of the rotating bead 10. The bottom end of the connecting ring 12 is fixedly connected to a sliding rod. The bottom end of the sliding rod is slidably installed with a motor 13. A threaded rod 14 is fixedly connected to the top of the motor 13. A groove block 15 is fixedly installed on one side of the baffle 5. An insertion block 16 is slidably installed on one side of the groove block 15. A threaded block 18 is threadedly installed on the side of the insertion block 16 away from the groove block 15. A second spring 17 is fixedly connected to one side of the threaded block 18. A pulling block 22 is slidably installed inside the insertion block 16. A pulling rope 21 is fixedly connected to the bottom end of the pulling block 22. A clamping block 19 is fixedly installed at one end of the pulling rope 21 away from the pulling block 22. And a third spring 20 is sleeved on the surface of the pulling rope 21. A bolt 23 is threadedly installed on one side of the placement box 1. A plug rod 24 is inserted into the bolt 23. An auxiliary block 25 is fixedly connected to one side of the plug rod 24. The sides of the two cleaning plates 6 close to each other are slidably installed on the surface of the powder outlet blade 4. The size specifications of the surfaces of the two cleaning rods are adapted to the size specifications of the surface of the powder outlet blade 4. The bottom end of the slide rail 9 is fixedly connected to the top of the powder outlet blade 4.

[0037] In this implementation, by setting the slider 8 to slide in the slide rail 9, the cleaning plate 6 at the bottom end of the clamping plate 7 slides on both sides of the powder outlet blade 4 to clean the toner on the surface of the powder outlet blade 4. Using the structure of the device that can clean the surface of the powder outlet blade 4, it avoids the toner adhering to the powder outlet blade 4 after long-term use, and a large amount of toner accumulates on the surface of the powder outlet blade 4 and condenses into blocks, resulting in toner imprints remaining on the printed paper during printing, affecting the printing quality.

[0038] Embodiment Two:

[0039] As Figures 1-6 shown, on the basis of Embodiment One, the present invention provides a technical solution: the two clamping plates 7 are rotatably installed with each other. The cross-section of the slider 8 is in a "U" shape structure, and the inner wall of the slider 8 is rotatably installed at the connection with the two clamping plates 7. The inner wall of the connecting ring 12 is threadedly installed on the surface of the threaded rod 14. The surface of the motor 13 is fixedly connected to the inside of the powder outlet blade 4. The center of the motor 13 and the center of the threaded rod 14 are on the same vertical line. The size specifications of one side of the threaded rod 14 are adapted to the size specifications of one side of the slide rail 9.

[0040] In this embodiment, the first spring 11 presses the clamping plates 7 on both sides, causing the bottom ends of the clamping plates 7 to fit against the surface of the powder outlet knife 4. The elastic force of the first spring 11 is used to make the two clamping plates 7 fit against the surface of the powder outlet knife 4, preventing the upper part of the powder outlet knife 4 from being wider than the lower part and ensuring that when the cleaning plate 6 moves up and down, it can fit against both sides of the powder outlet knife 4. Otherwise, the cleaning plate 6 may not clean thoroughly. The motor 13 controls the rotation of the sliding rod, causing the connecting ring 12 at its upper end to rotate on the surface of the threaded rod 14 and move up and down. The rotating ball 10 changes its position following the movement of the connecting ring 12, causing the slider 8 connected to the cleaning plate 6 to move up and down. The structure using the threaded rod 14 enables the cleaning plate 6 to move slowly up and down, preventing the cleaning plate 6 from moving too fast and scratching the surface of the powder outlet knife 4 or damaging the internal parts of the machine body, which would affect the use of the toner cartridge.

[0041] Embodiment Three:

[0042] As Figures 1-6 shown, based on Embodiment One and Embodiment Two, the present invention provides a technical solution: the size specifications of the surface of the insertion block 16 are adapted to the inner wall size specifications of the groove block 15. The surface of the clamping block 19 is clamped inside the groove block 15. The cross-section of the clamping block 19 is triangular. The bottom end of the clamping block 19 is rotatably installed on the surface of the insertion block 16, and there are at least two clamping blocks 19. One end of the third spring 20 is fixedly installed on one side of the clamping block 19, and the end of the third spring 20 far from the clamping block 19 is fixedly installed on the inner wall of the insertion block 16. The centers of the threaded block 18 and the second spring 17 are on the same straight line. The surface of the pull rope 21 is slidably installed inside the insertion block 16, and there are at least two pull ropes 21. The surface of the pull block 22 is provided with a pull groove.

[0043] In this embodiment, the insertion block 16 is used to connect the second spring 17 to the groove block 15. When separating the two components, the insertion block 16 is taken out of the groove block 15. The two clamping blocks 19 are stuck inside the groove block 15 by the elastic force of the third spring 20, thus fixing the insertion block 16 on the groove block 15. The structure that allows the spring to be detached from the groove block 15 by sliding the slider 8 is used to prevent the spring from falling off or being deformed due to the pulling force during the disassembly of the two components, which would cause inconvenience in disassembly. When the second spring 17 is damaged and cannot be used, the threaded block 18 is rotated to take out the second spring 17 from inside the insertion block 16 and replace it with a new spring. The structure that the second spring 17 can be disassembled by rotating the threaded block 18 is used to avoid difficulty in replacement when the second spring 17 is damaged. The tool is stuck in the pull groove on the pull block 22, and the pull block 22 is lifted upward, causing the pull rope 21 at the bottom end of the pull block 22 to pull the clamping block 19, making the clamping block 19 disengage from the groove block 15 and retract into the insertion block 16. By lifting the pull block 22, the clamping block 19 can be made to release the fixation on the slider 8, making the installation and disassembly more convenient.

[0044] Embodiment Four:

[0045] As Figures 1-6 shown, based on the first embodiment, the second embodiment, and the third embodiment, the present invention provides a technical solution: the surface of the insertion rod 24 is slidably installed inside the placement box 1. The cross-section of the insertion rod 24 is in a "Z" shape. There are at least two insertion rods 24. The auxiliary block 25 is a rubber block, and the surface of the auxiliary block 25 is clamped inside the placement box 1.

[0046] In this embodiment, the bolt 23 is rotatably installed inside the placement box 1 to fix it to the baffle 5. The insertion rod 24 is slid and inserted into the placement box 1, and the bolt 23 is fixed. The auxiliary block 25 made of rubber is stuck inside the placement box 1 to prevent the sliding rod from detaching from the placement box 1 due to vibration. The bolt 23 can be rotated without tools, avoiding the difficulty of detaching the baffles 5 on both sides of the placement box 1 due to tool limitations, and the user cannot clean its interior for a long time, resulting in the accumulation of toner inside.

[0047] The working principle and usage process of the present invention: The slider 8 slides inside the slide rail 9, so that the cleaning plate 6 at the bottom of the clamping plate 7 slides on both sides of the powder outlet knife 4 to clean the toner on the surface of the powder outlet knife 4. The structure of the device that can clean the surface of the powder outlet knife 4 is used to avoid the toner adhering to the powder outlet knife 4 after long-term use, and a large amount of toner accumulates and condenses into blocks on the surface of the powder outlet knife 4, resulting in toner imprints remaining on the printed paper during printing, affecting the printing quality. The first spring 11 squeezes the clamping plates 7 on both sides so that the bottom end of the clamping plate 7 fits the surface of the powder outlet knife 4. The elastic force of the first spring 11 is used to fit the two clamping plates 7 to the surface of the powder outlet knife 4, avoiding the upper part of the powder outlet knife 4 being wider than the lower part, and the cleaning plate 6 cannot fit the two sides of the powder outlet knife 4 when moving up and down, resulting in incomplete cleaning of the cleaning plate 6. The motor 13 controls the rotation of the sliding rod so that the connecting ring 12 at its upper end rotates on the surface of the threaded rod 14 and moves up and down. The rotating bead 10 changes its position following the movement of the connecting ring 12, causing the slider 8 connected to the cleaning plate 6 to move up and down. The structure that the cleaning plate 6 can move slowly up and down by using the threaded rod 14 is used to avoid the cleaning plate 6 moving too fast, scratching the surface of the powder outlet knife 4, or damaging the internal parts of the machine body, affecting the use of the toner cartridge.

[0048] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
