Description

Technical Field

[0001] This utility model relates to the field of toner cartridge technology, specifically to a low-static, anti-jamming toner cartridge. Background Technology

[0002] In modern office environments, laser printers are widely used due to their efficient and high-quality printing output. As the core component of laser printers, the performance of toner cartridges directly affects print quality and printer stability. Currently, with the continuous increase in printing workload and the continuous improvement in printing efficiency requirements, existing toner cartridges are gradually revealing some problems that urgently need to be solved.

[0003] Regarding static electricity, existing toner cartridges are prone to generating static electricity during operation due to the interaction between the photosensitive drum, charging roller, and toner. For example, the static electricity problem is particularly prominent in some relatively dry office environments. When static electricity accumulates to a certain level, it can lead to uneven toner adsorption, resulting in blurry text and distorted images in printed documents. More seriously, static electricity attracts dust and impurities from the surrounding air. These dust and impurities adhere to the internal components of the toner cartridge, affecting not only the normal lifespan of the toner cartridge but also potentially causing printer malfunctions. In addition, static electricity can interfere with the printer's electronic components, affecting data transmission and signal processing, and reducing the overall performance of the printer. Regarding paper jams, traditional toner cartridges often experience frequent paper jams due to various factors during paper transport. When paper passes through the toner cartridge, the paper is easily subjected to uneven friction due to the imperfect internal structure design of the toner cartridge. Utility Model Content

[0004] In view of the problems existing in the current toner cartridges, this utility model is proposed.

[0005] Therefore, the purpose of this utility model is to provide a low-static anti-paper-jamming toner cartridge, which solves the problems of static electricity accumulation affecting print quality, attracting dust and impurities, and frequent paper jams in existing toner cartridges.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A low-static, anti-jamming toner cartridge includes a cartridge body, a photosensitive drum rotatably mounted on the inner wall of the cartridge body, a drum bearing rotatably mounted on the outer wall of the photosensitive drum, the drum bearing being fixedly connected to the cartridge body, a charging roller rotatably mounted on the inner wall of the cartridge body, an anti-static film fixedly mounted on the outer wall of the charging roller, a toner compartment fixedly mounted on the inner wall of the cartridge body, a toner outlet fixedly mounted at the bottom of the toner compartment, a toner scraper fixedly mounted at the bottom of the toner outlet, a first motor fixedly mounted on one side wall of the cartridge body, a stirring paddle fixedly mounted at the output end of the first motor, the stirring paddle being rotatably connected to the inner wall of the toner compartment, an anti-jamming structure fixedly mounted on one side of the cartridge body, and an anti-static coating fixedly mounted on both the outer wall of the charging roller and the inner wall of the toner compartment.

[0008] Preferably, the anti-paper jam structure includes two sets of guide rollers and a second motor. The inner side wall of the drum body is provided with two sets of guide rollers, each set having two rollers. The outer side of the drum body is fixedly provided with two second motors, and the output ends of the two second motors are respectively fixedly connected to one of the guide rollers in each set.

[0009] Preferably, a grounding wire is fixedly provided at the bottom of the drum body, and an electrostatic discharge contact is fixedly provided on one side of the drum body.

[0010] Preferably, the outer wall of the photosensitive drum is fixedly provided with a groove and a protrusion, the depth of the groove is 0.01mm-0.05mm, and the height of the protrusion is 0.02mm-0.06mm.

[0011] Furthermore, a temperature sensor and a humidity sensor are fixedly installed on the main body of the toner cartridge.

[0012] Preferably, glass fiber cotton is fixedly provided on the inner sidewall of the guide roller.

[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0014] 1. This utility model effectively suppresses the accumulation of static electricity and reduces its impact on print quality by setting an antistatic coating made of graphene composite material on the surface of the charging roller and a polyimide static dissipation film in the contact area between the charging roller and the photosensitive drum. This results in clear text and realistic images in the printed documents. At the same time, it reduces the adsorption of surrounding dust and impurities by static electricity, extending the service life of the toner cartridge. The stirring device prevents toner from clumping and ensures the fluidity of toner in the toner hopper, allowing for smooth toner output. The guide rollers set on the paper transport path effectively prevent paper jams. The anti-slip surface and special structure of the guide rollers ensure that the paper maintains a stable forward direction during transport, greatly improving the printer's working efficiency.

[0015] 2. In this invention, the externally installed electrostatic discharge device can promptly release the static electricity generated inside the toner cartridge to the ground, preventing damage to the printer from static electricity, protecting the printer's electronic components, and improving the printer's stability. The roughening treatment process on the surface of the photosensitive drum increases the adhesion between the toner and the surface of the photosensitive drum, reducing the impact of static electricity on toner adsorption and further improving print quality. The antistatic coating on the inner wall of the toner cartridge prevents toner from adsorbing and accumulating static electricity on the inner wall of the toner cartridge, ensuring normal toner output and improving the performance of the toner cartridge.

[0016] 3. In this utility model, the sound-absorbing material filled inside the guide roller shaft reduces the noise generated during the rotation of the guide roller, providing users with a relatively quiet office environment. The temperature and humidity sensors can monitor the temperature and humidity inside the toner cartridge in real time and transmit the data to the printer's control system so that users can take timely measures to adjust the temperature and humidity of the office environment, ensure the normal operation of the toner cartridge, and improve the adaptability and reliability of the toner cartridge.
