Description

Technical Field

[0001] This utility model relates to the field of copier toner cartridge installation structure, specifically a copier toner cartridge installation structure. Background Technology

[0002] A toner cartridge, also known as a toner box or ink cartridge, is a component in laser printers and copiers used to store and supply printing toner. The toner cartridge contains powdered toner, which is a mixture of fine carbon particles and polymers used to form images and text during the printing process.

[0003] In the prior art, such as in publication number CN222914045U, a toner cartridge installation structure for a copier is disclosed. This structure includes a copier body and a toner cartridge. The toner cartridge is connected to the inner wall of a groove on one side of the copier body via two connecting devices. By removing the toner cartridge from the groove and adding toner, and then reinserting it into the groove, the toner cartridge is pressed against a fixing plate and a telescopic spring by an inclined surface on one side of a limiting plate. This causes the limiting plate to re-insert into the groove on the toner cartridge, thus reinstalling it. This device reduces operational complexity and time costs, and decreases the probability of frequent screw removal and installation causing thread damage and making it difficult to securely fix the toner cartridge inside the copier, thereby reducing the impact on copier stability and print quality.

[0004] While the aforementioned patent can compress and fix the toner cartridge through the design of the limiting plate and spring, the presence of a hard structure in contact with the toner cartridge will cause wear and tear on the surface of the toner cartridge over time. In addition, toner may fall inside the toner cartridge compartment used to install the toner cartridge, and some of the scattered toner will fall to the bottom surface during the installation and removal of the toner cartridge, causing contamination. Therefore, a copier toner cartridge installation structure is proposed to address the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, where a rigid structure contacts the toner cartridge, long-term wear and tear on the cartridge surface is a concern. Furthermore, toner can fall into the cartridge compartment, causing contamination when the cartridge is installed or removed. This invention proposes a new toner cartridge installation structure for copiers.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The toner cartridge installation structure of the copier described in this utility model includes a toner cartridge compartment provided on the side of the copier, a groove provided on the inner top wall of the toner cartridge compartment, a cleaning component fixedly connected inside the groove, a cover plate hinged to the side of the toner cartridge compartment, a positioning component fixedly connected to the side of the cover plate, and a toner cartridge provided inside the toner cartridge compartment.

[0007] The positioning component includes an airbag fixedly connected to the side of the cover plate. An air inlet is provided on the side of the airbag. A gas one-way valve is fixedly connected to one side of the air inlet. A hose is sleeved on the surface of the gas one-way valve. An inflatable ball is sleeved at one end of the hose.

[0008] The cleaning assembly includes a slide groove fixedly connected inside the groove. A drive motor is fixedly connected to one end of the slide groove. A lead screw is fixedly connected to the output end of the drive motor. A slider is threaded onto the surface of the lead screw. A connecting plate is fixedly connected to the bottom surface of the slider. A scraper is fixedly connected to the bottom surface of the connecting plate.

[0009] Preferably, the airbag contacts the outer wall of the powder box when it is inflated and is squeezed and deformed when the cover is closed to fix the powder box.

[0010] Preferably, the scraper extends to the bottom surface of the inner wall of the toner cartridge compartment for scraping off toner that has fallen from the toner cartridge onto the inner wall of the toner cartridge compartment.

[0011] Preferably, when the drive motor drives the lead screw to rotate, it causes the slider to move linearly along the slide groove, thereby causing the scraper to reciprocate along the inner wall of the powder box compartment.

[0012] Preferably, when the airbag is compressed and deformed, it cushions the rigid impact on the powder box through elastic deformation.

[0013] Preferably, the drive motor drives the lead screw to rotate in both directions to achieve bidirectional cleaning motion of the scraper on the inner wall of the powder box compartment.

[0014] The advantages of this utility model are:

[0015] 1. This utility model uses the airbag structure in the positioning component on the side of the cover plate, in conjunction with the gas one-way valve and the inflation ball to achieve airbag inflation and expansion. When the cover plate is closed, the airbag is squeezed and deformed by the powder box to produce elastic deformation, which avoids the hard components from directly contacting the powder box surface, and eliminates the risk of wear while fixing the powder box.

[0016] 2. This utility model uses a drive motor in the cleaning assembly to drive the lead screw to rotate, which in turn drives the slider to move linearly along the slide groove. This causes the scraper at the bottom of the connecting plate to reciprocate on the bottom surface of the inner wall of the toner cartridge compartment, actively scraping off the toner that has fallen from the toner cartridge and preventing toner from scattering and causing pollution during disassembly and assembly.

[0023] 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 scope of protection of the present utility model.

[0024] Please see Figures 1-4 As shown, a toner cartridge installation structure for a copier includes a copier 1, a toner cartridge compartment 2 on the side of the copier 1, a groove on the inner top wall of the toner cartridge compartment 2, a cleaning component 3 fixedly connected inside the groove, a cover plate 4 hinged to the side of the toner cartridge compartment 2, a positioning component 5 fixedly connected to the side of the cover plate 4, and a toner cartridge 6 disposed inside the toner cartridge compartment 2.

[0025] Positioning component 5 includes an airbag 51 fixedly connected to the side of cover plate 4. An air inlet is provided on the side of the airbag 51. A gas one-way valve 52 is fixedly connected to one side of the air inlet. A hose 53 is sleeved on the surface of the gas one-way valve 52. An inflatable ball 54 is sleeved on one end of the hose 53.

[0026] During operation, the airflow is transmitted through the hose 53 by squeezing the inflation ball 54, and injected into the airbag 51 through the gas one-way valve 52. After the airbag 51 expands, the cover plate 4 is closed. The expanded airbag 51 contacts the outer wall of the powder box 6 and is squeezed and deformed. Through its own elastic deformation, it applies a flexible fixing force to the powder box 6, while eliminating the risk of wear caused by the rigid components directly contacting the surface of the powder box 6.

[0027] Furthermore, the cleaning component 3 includes a slide 31 fixedly connected inside the groove. A drive motor 32 is fixedly connected to one end of the slide 31. A lead screw 33 is fixedly connected to the output end of the drive motor 32. A slider 34 is threadedly connected to the surface of the lead screw 33. A connecting plate 35 is fixedly connected to the bottom surface of the slider 34. A scraper 36 is fixedly connected to the bottom surface of the connecting plate 35.

[0028] During operation, the drive motor 32 is started to drive the lead screw 33 to rotate in both directions, causing the threaded slider 34 to move linearly back and forth along the slide groove 31. This, in turn, drives the scraper 36 at the bottom of the connecting plate 35 to continuously scrape the bottom surface of the inner wall of the toner box 2, actively pushing the toner that falls from the toner box 6 to the centralized recycling area, thus preventing toner from scattering and contaminating the equipment during disassembly and assembly.

[0029] Furthermore, when the airbag 51 is compressed and deformed, it cushions the rigid impact on the powder box 6 through elastic deformation.

[0030] During operation, when the cover plate 4 is closed, the inflated airbag 51 is squeezed by the powder box 6 and undergoes elastic deformation. Through its own flexibility, it absorbs the rigid impact force between the powder box 6 and the cover plate 4, thereby fixing the powder box 6 while avoiding surface wear caused by hard contact.

[0031] Furthermore, the drive motor 32 drives the lead screw 33 to rotate in both directions to achieve bidirectional cleaning motion of the scraper 36 on the inner wall of the powder box compartment 2;

[0032] During operation, the drive motor 32 receives control signals to rotate the lead screw 33 in both directions, driving the slider 34 to move back and forth along the slide groove 31, so that the scraper 36 can achieve bidirectional scraping on the bottom surface of the inner wall of the toner cartridge compartment 2, thereby significantly improving the toner cleaning coverage and preventing residual pollution caused by unidirectional movement.

[0033] Working principle: During operation, after the toner cartridge 6 is placed inside the toner cartridge compartment 2, the inflatable ball 54 of the positioning component 5 is squeezed to allow airflow to pass through the hose 53 and the gas one-way valve 52 into the airbag 51. After the airbag 51 expands, the cover plate 4 closes. The expanded airbag 51 contacts the outer wall of the toner cartridge 6 and is squeezed, causing elastic deformation. The deformation pressure fixes the toner cartridge 6 while buffering rigid impact. The drive motor 32 of the cleaning component 3 is started to rotate the lead screw 33 in both directions. The slider 34, which is threaded on the surface of the lead screw 33, moves linearly back and forth along the slide groove 31. This causes the scraper 36 on the bottom connecting plate 35 of the slider 34 to scrape the bottom surface of the inner wall of the toner cartridge compartment 2 in both directions, removing the toner that has fallen from the toner cartridge 6.

[0034] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, or similar improvements made within the theoretical and principle content of the present utility model should be included within the protection scope of the present utility model.
