Abstract
Description
Technical Field
[0001] This utility model relates to the field of printer cleaning technology, and in particular to a printer residual toner fixing and cleaning device. Background Technology
[0002] In modern office environments, printers have become indispensable equipment. During the printing process, the fusing unit is a key component that ensures that toner adheres firmly to the paper. However, after long-term use, a large amount of toner will remain on the surface of the fusing roller and pressure roller in the fusing unit. The residual toner will not only lead to a decrease in print quality, such as blurry text and image ghosting, but will also affect the normal rotation of the fusing roller and pressure roller, accelerate component wear, and shorten the life of the printer.
[0003] Currently, most printer residual toner cleaning devices on the market only clean the surface of the fuser roller, lacking effective treatment of residual toner when the fuser roller and pressure roller work together. Some cleaning devices use a simple wiping structure, which cannot completely remove stubborn residual toner. Some cleaning devices are equipped with scrapers, but due to poor coordination between the cleaning roller and the scraper, the toner cleaning efficiency is low, and the cleaned toner cannot be properly collected and disposed of, which can easily cause secondary pollution and affect the normal operation of other internal components of the printer.
[0004] Therefore, we provide a printer residual toner fixing and cleaning device. Utility Model Content
[0005] The purpose of this invention is to address the aforementioned technical problems by providing a printer residual toner fixing and cleaning device, which solves the problems of incomplete cleaning, low cleaning efficiency, and poor toner collection and processing in existing printer residual toner cleaning devices.
[0006] In view of this, the present invention provides a printer residual toner fixing and cleaning device, including a printer body, a folding cover, a fixing component, a cleaning roller, a scraper and a collection plate;
[0007] The folding cover is hinged to the printer body;
[0008] The fusing unit includes a fusing roller and a pressure roller, and the printer body is provided with a drive mechanism, which is used to control the rotation of the fusing roller and the pressure roller in the fusing unit.
[0009] The cleaning roller is located on one side of the printer fuser assembly, its length is adapted to the length of the fuser assembly, and it is made of an absorbent material.
[0010] The scraper is installed on the left side of the cleaning roller and is in close contact with the cleaning roller, with its blade forming a certain angle with the outer surface of the cleaning roller.
[0011] The collecting plate is positioned below the scraper.
[0012] Preferably, the cleaning roller is mounted on the structural blocks at both ends via a movable shaft. The structural blocks at both ends are connected to the adjustment channel inside the printer body by springs. The upper surface of the structural block is a sloped structure, which matches the sloped surface at the lower end of the limiting block. When the limiting blocks at both ends are inserted into the adjustment channel, the structural block and the limiting block together fill the adjustment channel, forming a stable installation structure.
[0013] Preferably, when the structural block and the limiting block fill the adjustment channel, the cleaning roller and the fixing component maintain a certain distance. When the limiting block is pulled out from the adjustment channel, the spring loses its squeezing effect and begins to reset. Under the action of the elastic force, the cleaning roller is pushed towards the fixing component until one end face of the cleaning roller touches the fixing component.
[0014] Preferably, the lower end of the inclined surface of the limiting block has a limiting protrusion extending downwards. When the limiting block is inserted into the adjustment channel, the limiting protrusion abuts against the road surface along the path of the structural block.
[0015] Preferably, the limiting blocks at the left and right ends are connected by an integral structure of the middle horizontal plate, and an auxiliary handle is provided in the middle of the horizontal plate.
[0016] Preferably, the scraper is provided in multiple sets, and the multiple sets of scrapers are mounted on the guide post through a hinge seat. The guide post is mounted on the side close to the cleaning roller with the fixing plates at both ends.
[0017] Preferably, the multiple sets of scrapers are mounted via torsion springs within the hinge seat. The rotation direction of the torsion springs is between 0 and 90° to the right. When the limiting block disengages from the adjustment channel, the cleaning roller comes into contact with the cleaning part of the fixing component. At this time, the multiple sets of scrapers are affected by the torsion springs and rotate together in the direction of movement of the cleaning roller until the multiple sets of scrapers rotate 45° and come into contact with the outer surface of the cleaning roller.
[0018] Compared with the prior art, this utility model provides a printer residual toner fixing and cleaning device, which has the following beneficial effects:
[0019] 1. In this utility model, the length of the cleaning roller in the device is adapted to the fixing assembly, and it can move under the action of a spring to abut against the fixing component. It works with the scraper to clean the surface of the fixing roller and the pressure roller. At the same time, it can also treat the residual toner when the fixing roller and the pressure roller work together, which makes up for the lack of cleaning range of traditional devices and achieves effective cleaning of multiple parts of the fixing component.
[0020] 2. In this invention, the cleaning roller, through the cooperation of a spring and an adjustment channel, automatically abuts against the fixing component under the action of elasticity after the limiting block is pulled out. At the same time, multiple sets of scrapers are closely attached to the cleaning roller due to the influence of torsion springs, ensuring that the cleaning roller, scrapers and fixing component always maintain the best cleaning contact state. Compared with the traditional fixed structure, it can effectively cope with wear or installation errors under different usage scenarios, thoroughly remove stubborn toner from the surface and mating area of the fixing roller and pressure roller, and significantly improve cleaning efficiency and effect.
[0021] 3. This utility model, by having multiple sets of scrapers simultaneously abut against the cleaning roller, can form a denser scraping coverage on the surface of the cleaning roller compared to a traditional single set of scrapers. It can scrape away stubborn toner adsorbed on the cleaning roller from multiple angles, significantly improving toner cleaning efficiency and ensuring that residual toner on the surface of the cleaning roller is completely removed, thereby ensuring the cleaning effect of the fixing component. Furthermore, the scraper automatically rotates and fits against the hinge seat through the torsion spring. When the cleaning roller abuts against the fixing component, the scraper can adaptively adjust its angle to 45° to tightly fit against the outer surface of the cleaning roller. This design can effectively compensate for unevenness on the surface of the cleaning roller or wear caused by long-term use, always maintaining the best contact state, avoiding cleaning dead corners, and ensuring the long-term stable cleaning performance of the cleaning device.
[0022] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model has a simple structure and is easy to operate. Attached Figure Description

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.
[0029] Example:
[0030] Please see Figure 1 - Figure 4 This embodiment of a printer residual toner fixing and cleaning device includes: a printer body 1, a hinged cover 2, a fixing component, a cleaning roller 3, a scraper 101, and a collection plate 12; the hinged cover 2 is hinged to the printer body 1; the fixing component includes a fixing roller and a pressure roller, and a drive mechanism is provided inside the printer body 1 to control the rotation of the fixing roller and the pressure roller in the fixing component; the cleaning roller 3 is disposed on one side of the printer fixing component, its length is adapted to the length of the fixing component, and it is made of an absorbent material; the scraper 101 is installed on the left side of the cleaning roller 3, closely fitting the cleaning roller 3, and its blade forms a certain angle with the outer surface of the cleaning roller 3; the collection plate 12 is disposed below the scraper 101.
[0031] Among them, the length of the cleaning roller 3 is adapted to the fixing assembly, and it can simultaneously cover the entire axial width of the fixing roller and the pressure roller, avoiding the cleaning blind spots in the edge area of traditional cleaning devices. Combined with the design of the adsorbent material and the doctor blade 101, it can efficiently peel off and adsorb the molten toner remaining during the fixing process.
[0032] The cleaning roller 3 is mounted on the structural blocks 5 at both ends via the movable shaft 4. The structural blocks 5 at both ends are connected to the adjustment channel 11 inside the printer body 1 by springs 7. The upper surface of the structural block 5 is a sloped structure, which matches the sloped surface at the lower end of the limiting block 6. When the limiting blocks 6 at both ends are inserted into the adjustment channel 11, the structural block 5 and the limiting block 6 together fill the adjustment channel 11, forming a stable installation structure.
[0033] The cleaning roller 3, through the spring 7 and the adjustment channel 11, can automatically reach the fixing component under the action of elasticity after the limit block 6 is pulled out. At the same time, multiple sets of scrapers 101 are closely attached to the cleaning roller 3 under the influence of torsion springs, ensuring that the cleaning roller 3, scrapers 101 and fixing component always maintain the best cleaning contact state. Compared with the traditional fixed structure, it can effectively cope with wear or installation errors under different usage scenarios, and thoroughly remove stubborn toner from the surface and mating parts of the fixing roller and pressure roller, significantly improving cleaning efficiency and effect.
[0034] When the structural block 5 and the limiting block 6 fill the adjustment channel 11, the cleaning roller 3 maintains a certain distance from the fixing component. When the limiting block 6 is pulled out from the adjustment channel 11, the spring 7 loses its squeezing effect and begins to reset. Under the action of the elastic force, it pushes the cleaning roller 3 to move towards the fixing component until one end of the cleaning roller 3 touches the fixing component.
[0035] Among them, the lower end of the inclined surface of the limiting block 6 has a limiting protrusion 61 extending downward. When the limiting block 6 is inserted into the adjustment channel 11, the limiting protrusion 61 abuts against the road surface of the structural block 5.
[0036] The left and right end limit blocks 6 are connected by an integral structure through the middle horizontal plate 63, and an auxiliary handle 64 is provided in the middle of the horizontal plate 63.
[0037] The scraper 101 is provided in multiple sets, and the multiple sets of scrapers 101 are mounted on the guide post 8 through the hinge seat 10. The guide post 8 is mounted on the side close to the cleaning roller 3 with the fixing plates 9 at both ends.
[0038] Multiple sets of scrapers 101 are mounted via torsion springs within the hinge seat 10. The torsion springs rotate between 0 and 90 degrees to the right. When the limit block 6 disengages from the adjustment channel 11, the cleaning roller 3 comes into contact with the cleaning part of the fixing component. At this time, the multiple sets of scrapers 101 are affected by the torsion springs and rotate together in the direction of movement of the cleaning roller 3 until the multiple sets of scrapers 101 rotate 45 degrees and come into contact with the outer surface of the cleaning roller 3.
[0039] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. As long as they can achieve their beneficial effects, they can be implemented. Therefore, this embodiment will not elaborate on their specific structural composition and working principle.
[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
