Description

Technical Field

[0001] This utility model relates to the field of printer accessories technology, and in particular to a toner cartridge structure. Background Technology

[0002] In the operation of a printer, the toner cartridge, as the core component for printing images and text, has a structural design and assembly process that directly affects print quality and production efficiency. The toner cartridge, as a key component for holding the developer and performing the developing function, requires the installation of important parts such as the developing roller and the first cleaning blade. The way these components are installed has a significant impact on the overall assembly efficiency of the toner cartridge.

[0003] In existing technology, the installation of the developing roller and the first cleaning blade inside the toner cartridge employs a step-by-step assembly process. Specifically, the developing roller is installed using a rear-mounted snap-fit ​​method, meaning the operator must push the developing roller from back to front along the pre-set snap-fit ​​structure inside the toner cartridge to position and fix it. However, after the developing roller is installed, the spatial constraints between the installation positions of the first cleaning blade and the developing roller within the toner cartridge, and the fact that the existing toner cartridge structure does not adequately accommodate their installation orientations, force the operator to manually flip the toner cartridge before the first cleaning blade can be snapped in and fixed vertically from top to bottom through the top opening of the toner cartridge.

[0004] This assembly method has obvious drawbacks: On the one hand, manually flipping the toner cartridge adds an extra step, making the entire toner cartridge assembly process cumbersome. In large-scale mass production scenarios, this significantly increases the assembly time of a single toner cartridge, directly reducing the overall assembly efficiency on the production line. On the other hand, during the flipping process, the toner cartridge and the installed developing roller are prone to shaking or collisions due to improper operation, which may not only damage the components and affect the product qualification rate, but also increase the labor intensity of the operators, further restricting the improvement of assembly efficiency.

[0005] It is evident that the existing installation method of the developing roller and the first cleaning blade in the toner cartridge has the problem of low assembly efficiency due to the need for manual rotation of the toner cartridge, which is difficult to meet the needs of modern high-efficiency production. Therefore, it is necessary to improve it. Utility Model Content

[0006] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a toner cartridge structure that is easy to assemble.

[0007] A toner cartridge structure designed for this purpose includes a toner hopper, a developing roller, and a first cleaning blade. The toner hopper is provided with a toner outlet that runs through the front and back. The developing roller and the first cleaning blade are located in front of the toner outlet.

[0008] The powder hopper has front-opening mounting spaces on its left and right sides, and the developing roller is at least partially located within the mounting spaces.

[0009] The powder hopper is provided with a mounting base, the mounting base is provided with a threaded hole with a front opening, the first cleaning scraper is provided with a mounting hole corresponding to the threaded hole, and a screw that is threadedly connected to the threaded hole passes through the mounting hole.

[0010] Preferably, the first cleaning scraper is provided with a connecting lug, and the mounting hole is provided on the connecting lug.

[0011] Preferably, the front surface of the powder hopper is provided with a contact surface that fits with the first cleaning scraper, and a sealing gasket is provided between the first cleaning scraper and the contact surface.

[0012] Preferably, there are two mounting bases, spaced apart on the left and right.

[0013] Preferably, the developing roller has a diameter of 12 mm.

[0014] Preferably, the system also includes a waste powder bin, which is equipped with a drum core and a second cleaning scraper that fits against the drum core.

[0015] Preferably, the waste powder bin is provided with a sealing contact portion, which at least partially abuts against the second cleaning scraper.

[0016] Compared with the prior art, this utility model can effectively solve the problem of low assembly efficiency caused by the need for manual flipping of the powder hopper in the prior art, and has the following beneficial effects:

[0017] On the one hand, by placing both the developing roller and the first cleaning blade in front of the powder outlet of the powder hopper, and cooperating with the installation space of the front openings on both sides of the powder hopper, the developing roller can be directly installed into the installation space from the front. At the same time, the first cleaning blade is installed by engaging with screws through the threaded holes of the front opening of the powder hopper, eliminating the need for manually flipping the powder hopper. This allows the developing roller and the first cleaning blade to be assembled in the same operating position, significantly simplifying the assembly process, greatly shortening the assembly time of a single toner cartridge, and effectively improving the overall assembly efficiency of the production line.

[0018] On the other hand, since there is no need to flip the powder hopper, the risk of shaking or collision of the powder hopper and the installed developing roller due to improper operation is avoided, reducing the probability of component damage and helping to improve the product qualification rate; at the same time, the labor intensity caused by flipping operation is reduced, further optimizing the convenience of assembly operations.

[0019] In summary, this toner cartridge structure, through its rational layout design, has significant advantages in improving assembly efficiency, ensuring product quality, and reducing labor intensity, and is better able to meet the needs of modern, efficient production.

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0026] See Figures 1-5 A toner cartridge structure includes a toner cartridge 10, a developing roller 20, and a first cleaning blade 30. The toner cartridge 10 has a toner outlet 100 extending from front to back. The developing roller 20 and the first cleaning blade 30 are located in front of the toner outlet 100. The left and right sides of the toner cartridge 10 have front-opening mounting spaces 110, and the developing roller 20 is at least partially located within the mounting spaces 110. The toner cartridge 10 has a mounting base 120 with a front-opening threaded hole 130. The first cleaning blade 30 has a mounting hole 320 corresponding to the threaded hole 130, and a screw threaded into the mounting hole 320 is threaded to the threaded hole 130.

[0027] The installation principle of this toner cartridge structure is based on the coordinated design of component layout and assembly sequence, as follows:

[0028] During assembly, the first cleaning scraper 30 can be placed in front of the powder outlet 100 of the powder hopper 10, so that the mounting hole 320 on the scraper is precisely aligned with the threaded hole 130 of the powder hopper mounting base 120. The first cleaning scraper 30 is fixedly installed by passing the screw through the mounting hole 320 and screwing it into the threaded hole 130 with the front opening. At this time, the scraper body is stably positioned in the preset position in front of the powder outlet 100.

[0029] Subsequently, the developing roller 20 is pushed into the mounting space 110 through the front openings on both sides of the powder hopper 10, so that the developing roller 20 is at least partially engaged within the mounting space 110. Because the front opening design of the mounting space 110 is adapted to the size of the developing roller 20, during the engagement process, the outer circumferential surface of the developing roller 20 will naturally contact the cutting edge or contact surface of the already fixed first cleaning blade 30. Through the limiting effect of the mounting space 110 on the developing roller 20, and the preset installation position of the first cleaning blade 30, the precise positioning of the developing roller 20 within the mounting space 110 is achieved, while ensuring that the developing roller 20 and the first cleaning blade 30 remain in close contact, thus completing the entire assembly process.

[0030] See Figures 1 to 4 The first cleaning scraper 30 is provided with a connecting lug 310, and the mounting hole 320 is provided on the connecting lug 310. The connecting lug 310 of the first cleaning scraper 30 provides a stable bearing structure for the mounting hole 320, which not only facilitates the precise alignment of the mounting hole 320 with the threaded hole 130 of the powder hopper mounting base 120, but also enhances the structural strength of the connection between the scraper and the powder hopper, preventing the scraper body from deforming due to installation stress, and ensuring that the first cleaning scraper 30 is stably positioned in the preset position, providing a reliable foundation for subsequent close contact with the developing roller 20.

[0031] In this invention, the front surface of the toner cartridge 10 is provided with a mating surface 140 that fits against the first cleaning blade 30, and a sealing gasket is provided between the first cleaning blade 30 and the mating surface 140. The mating surface 140 of the cartridge 10 provides a stable mounting reference for the first cleaning blade 30, ensuring a tight fit; the sealing gasket between the two enhances the sealing performance at the joint, effectively preventing developer leakage from gaps and ensuring print quality.

[0032] In this utility model, there are two mounting bases 120, which are spaced apart on the left and right.

[0033] In this invention, the diameter of the developing roller 20 is set to 12mm. Compared with the existing developing roller with a diameter of 14mm, under the same material and rotation speed conditions, the reduced roller radius reduces the inertial torque during rotation, which can effectively reduce the torque required to drive the developing roller to rotate, reduce the power demand on the driving components, help reduce energy consumption and extend the service life of the driving system.

[0034] See Figure 5 The present invention also includes a waste powder bin 40, wherein a drum core 50 and a second cleaning scraper 60 are installed in the waste powder bin 40.

[0035] See Figure 5 The waste powder bin 40 is provided with a sealing abutment part 410, which at least partially abuts against the second cleaning scraper 60.
