Description

Technical Field

[0001] This utility model relates to the field of toner cartridge technology, and more specifically, to a toner cartridge assembly anti-leakage sealing device. Background Technology

[0002] The toner leak prevention sealing device of the toner cartridge assembly is a systematic physical barrier and control mechanism integrated inside the toner cartridge. Its core function is to ensure that the toner is safely sealed in the toner hopper and precisely and controllably delivered to the surface of the photosensitive drum only at the moment of printing. This prevents toner from leaking in an unintended manner throughout the entire life cycle of the toner cartridge. However, due to the bottom sealing structure of existing toner cartridges, after refilling, some toner may clump together due to the long toner storage time. These clumps of toner may get stuck inside the toner cartridge, resulting in a deterioration in overall print quality. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, this utility model provides a toner cartridge assembly anti-leakage sealing device, which has the advantage of preventing clumped toner from entering the inside of the toner cartridge.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a toner cartridge assembly anti-leakage sealing device, comprising a toner cartridge, wherein a charging roller, a sponge roller and an OPC roller are rotatably connected inside the toner cartridge, a powder inlet is fixedly installed inside the toner cartridge, a sliding groove is provided inside the powder inlet, a slider is slidably connected inside the sliding groove, a filter plate is fixedly installed inside the slider, a filter hole and a pressing hole are provided inside the filter plate, a guide plate is fixedly installed inside the powder inlet, and a discharge port is fixedly installed at the bottom of the powder inlet.

[0005] As a preferred embodiment of this utility model, a bracket is fixedly installed inside the discharge port, a telescopic rod is fixedly installed above the bracket, a spring is sleeved on the outside of the telescopic rod, a sealing plate is fixedly installed above the spring, and a limiting ring is fixedly installed inside the discharge port, the limiting ring being located above the sealing plate and in contact with the sealing plate.

[0006] As a preferred embodiment of this utility model, the drum has a powder outlet inside, and a developing roller is provided at the bottom of the powder outlet. The developing roller is in contact with the sponge roller and is fixedly connected to the drum.

[0007] As a preferred embodiment of this utility model, a connecting shaft is provided on the outer side of the sponge roller, and telescopic rods are fixedly installed at the left and right ends of the connecting shaft. A spring is sleeved on the outer side of the telescopic rod, and a positioning plate is fixedly installed on the outer side of the spring. The positioning plate is engaged with the toner cartridge. A hanging plate is fixedly installed on the outer side of the connecting shaft, and the hanging plate is in contact with the sponge roller.

[0008] As a preferred embodiment of this utility model, there are two chutes, both of which are located inside the powder inlet, and there are two sliders, both of which are fixedly connected to the filter plate.

[0009] As a preferred embodiment of this utility model, there are multiple filter holes, all of which are located above the guide plate. There are two guide plates, and the two guide plates are inclined.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. This utility model features a sliding groove inside the toner inlet, a slider slidably connected inside the groove, a filter plate fixedly installed inside the slider, filter holes and pressing holes inside the filter plate, a guide plate fixedly installed inside the toner inlet, and a discharge port fixedly installed at the bottom of the toner inlet. When new toner needs to be injected, the clamping rod is first passed through the inside of the pressing hole, so that the edge of the clamping rod contacts the discharge port, making the pressing hole sealed. At this time, the toner will fall on the surface of the filter plate and fall into the inside of the toner inlet after being filtered through the filter holes. At this time, any clumps of toner will be filtered by the filter holes, thus preventing clumps of toner from entering the inside of the drum and causing a deterioration in printing performance.

[0012] 2. This utility model features telescopic rods fixedly installed at both ends of the connecting shaft. A spring is sleeved on the outside of the telescopic rod, and a positioning plate is fixedly installed on the outside of the spring, engaging with the toner cartridge. A hanging plate is also fixedly installed on the outside of the connecting shaft, contacting the sponge roller. During printing, the surface of the sponge roller absorbs a significant amount of toner, which then contacts the paper to achieve the printing effect. However, due to prolonged use, the toner concentration on the sponge roller may become uneven. As the sponge roller rotates, it contacts the hanging plate, allowing the hanging plate to clean the surface of the device promptly, maintaining a uniform toner concentration. When the hanging plate absorbs excessive toner, it needs to be cleaned promptly. Pressing the telescopic rod towards the connecting shaft causes the spring to retract, disengaging the telescopic rod from the toner cartridge for easy cleaning. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1 to 6 As shown, this utility model provides a leak-proof sealing device for a toner cartridge assembly, including a toner cartridge 1. A charging roller 2, a sponge roller 3, and an OPC roller 4 are rotatably connected inside the toner cartridge 1. A powder inlet 5 is fixedly installed inside the toner cartridge 1. A groove 6 is opened inside the powder inlet 5. A slider 7 is slidably connected inside the groove 6. A filter plate 8 is fixedly installed inside the slider 7. A filter hole 9 and a pressing hole 10 are opened inside the filter plate 8. A guide plate 11 is fixedly installed inside the powder inlet 5. A discharge port 12 is fixedly installed at the bottom of the powder inlet 5.

[0022] When new toner needs to be injected, first pass the lever through the inside of the pressing hole 10 so that the edge of the lever contacts the feed port 12, making the pressing hole 10 sealed. At this time, the toner will fall on the surface of the filter plate 8 and fall into the inside of the toner inlet 5 after being filtered by the filter hole 9. At this time, any clumps of toner will be filtered by the filter hole 9, thus preventing clumps of toner from entering the inside of the drum 1 and causing the printing condition to deteriorate.

[0023] The discharge port 12 is fixedly installed with a bracket 13 inside, and a telescopic rod 14 is fixedly installed above the bracket 13. A spring 15 is sleeved on the outside of the telescopic rod 14. A sealing plate 16 is fixedly installed above the spring 15. A limit ring 17 is fixedly installed inside the discharge port 12. The limit ring 17 is located above the sealing plate 16 and is in contact with the sealing plate 16.

[0024] Spring 15 provides elastic force to press the sealing plate 16 towards the limiting ring 17, so that the sealing plate 16 contacts the limiting ring 17, thereby keeping the inside of the feed port 12 sealed. When adding powder, first press the lever inserted into the pressing hole 10 downward, so that the lever contacts the sealing plate 16, thereby causing spring 15 and telescopic rod 14 to retract. At this time, the powder will fall downward through both sides of the sealing plate 16, making it easier for the powder to enter the inside of the toner cartridge 1. After the powder is added, the sealing plate 16 is reset to increase the overall sealing performance.

[0025] The drum 1 has a powder outlet 18 inside, and a developing roller 19 is provided at the bottom of the powder outlet 18. The developing roller 19 is in contact with the sponge roller 3 and is fixedly connected to the drum 1.

[0026] When printing is required, the powder accumulated inside the powder outlet 18 is first adsorbed by the surface of the developing roller 19. During the rotational connection between the developing roller 19 and the drum 1, it comes into contact with the sponge roller 3, so that the toner is adsorbed on the surface of the sponge roller 3, which facilitates subsequent printing. At the same time, the position of the developing roller 19 seals the bottom of the powder outlet 18 to prevent powder leakage.

[0027] Among them, the outer side of the sponge roller 3 is provided with a connecting shaft 20, and the left and right ends of the connecting shaft 20 are fixedly installed with telescopic rods 21. The outer side of the telescopic rods 21 is sleeved with springs 22. The outer side of the springs 22 is fixedly installed with a positioning plate 23. The positioning plate 23 is engaged with the drum 1. The outer side of the connecting shaft 20 is fixedly installed with a hanging plate 24, which is in contact with the sponge roller 3.

[0028] During printing, the surface of the sponge roller 3 will absorb a large amount of toner, which will then come into contact with the paper to achieve the printing effect. Due to prolonged use, the toner on the surface of the sponge roller 3 may become uneven in thickness. As the sponge roller 3 rotates, it comes into contact with the hanging plate 24, allowing the hanging plate 24 to clean the surface of the device in a timely manner and maintain a uniform toner thickness. At the same time, when the hanging plate 24 absorbs a large amount of toner, it needs to be cleaned in time. At this time, the telescopic rod 21 is pressed towards the connecting shaft 20, causing the spring 22 to retract and disengage the telescopic rod 21 from the drum 1, thus facilitating cleaning.

[0029] There are two chutes 6, both of which are located inside the powder inlet 5. There are two sliders 7, both of which are fixedly connected to the filter plate 8.

[0030] The filter plate 8 is installed and disassembled through the sliding connection of two sliders 7 and two grooves 6, so that the carbon powder clumped together after filtration can be cleaned in time, making it easy to install and clean.

[0031] There are multiple filter holes 9, all of which are located above the guide plate 11. There are two guide plates 11, and the two guide plates 11 are inclined.

[0032] The main function of the two guide plates 11 is that after the toner is filtered by multiple filter holes 9, it will fall onto the surface of the two guide plates 11. At this time, the toner will slide down the surface of the guide plates 11 under the action of gravity, so that the toner can accurately enter the interior of the feed port 12.

[0033] Working principle and usage process of this utility model:

[0034] Firstly, a groove 6 is provided inside the powder inlet 5, and a slider 7 is slidably connected inside the groove 6. A filter plate 8 is fixedly installed inside the slider 7. A filter hole 9 and a pressing hole 10 are provided inside the filter plate 8. A guide plate 11 is fixedly installed inside the powder inlet 5, and a discharge port 12 is fixedly installed at the bottom of the powder inlet 5. When new powder needs to be injected, the clamp rod is first passed through the inside of the pressing hole 10, so that the edge of the clamp rod contacts the discharge port 12, making the pressing hole 10 sealed. At this time, the powder will fall on the surface of the filter plate 8 and fall into the inside of the powder inlet 5 after being filtered by the filter hole 9. At this time, any clumps of powder will be filtered by the filter hole 9, thereby preventing clumps of powder from entering the inside of the drum 1 and causing the printing condition to deteriorate.

[0035] Secondly, a spring 15 is sleeved on the outside of the telescopic rod 14, and a sealing plate 16 is fixedly installed above the spring 15. The spring 15 provides elastic force to press the sealing plate 16 towards the limiting ring 17, so that the sealing plate 16 contacts the limiting ring 17, thereby keeping the inside of the feed port 12 sealed. When adding powder, the lever inserted into the pressing hole 10 is pressed down, so that the lever contacts the sealing plate 16, thereby causing the spring 15 and the telescopic rod 14 to retract. At this time, the powder will fall down through both sides of the sealing plate 16, making it easier for the powder to enter the inside of the toner cartridge 1. After the powder is added, the sealing plate 16 is reset to increase the overall sealing performance.

[0036] Finally, telescopic rods 21 are fixedly installed at both ends of the connecting shaft 20. Springs 22 are sleeved on the outside of telescopic rods 21, and positioning plates 23 are fixedly installed on the outside of springs 22. Positioning plates 23 are engaged with toner cartridges 1. At the same time, hanging plates 24 are fixedly installed on the outside of the connecting shaft 20 and contact the sponge roller 3. When printing, the surface of the sponge roller 3 will absorb a lot of toner and contact the paper to achieve the printing effect. Due to prolonged use, the toner on the surface of the sponge roller 3 may be uneven. During the rotation of the sponge roller 3, it contacts the hanging plate 24, allowing the hanging plate 24 to clean the surface of the device in time and maintain a uniform toner thickness. When the hanging plate 24 absorbs too much toner, it needs to be cleaned in time. At this time, the telescopic rods 21 are pressed towards the connecting shaft 20, causing springs 22 to retract and the telescopic rods 21 to disengage from the toner cartridge 1, making cleaning easier.
