Description

Technical Field

[0001] The utility model relates to the technical field of toner cartridges, in particular to an integrated toner cartridge with an automatic reset counting structure. Background Art

[0002] In the current printing technology field, traditional toner cartridges and drum frames usually require complex maintenance and manual reset processes to achieve the reuse of toner cartridges. For example, the toner cartridge of a TN1035 model printer consists of two parts: a drum frame and a toner cartridge. One side of the toner cartridge is equipped with a counting gear structure, which interacts with a driving gear assembly. When the printer is running, the driving gear assembly drives the counting gear structure to rotate, and then presses and releases an induction element inside the printer through the counting gear structure to complete the "printer recognition" process. After that, the empty tooth part of the counting gear structure rotates to the position meshing with the driving gear assembly, thus stopping the operation of the counting gear. However, when the toner in the toner cartridge is exhausted and the user needs to reload the toner for reuse, the toner cartridge must be manually removed from the drum frame, and the gear side cover of the toner cartridge must be disassembled, and tools are used to rotate the counting gear structure so that it meshes with the driving gear assembly again. This process is not only complex, but for users who are not familiar with the disassembly and assembly principles of toner cartridges, it may cause damage to the reusable toner cartridge, resulting in waste of resources. Moreover, before the toner cartridge is installed in the printer, the toner cartridge needs to be fitted in the drum frame for the installation of the developing roller and the drum core. This may cause the direct fit between the toner cartridge and the drum frame to gradually become loose due to multiple assembly insertions and extractions, resulting in unstable installation and poor printing stability. There may also be an offset error in the fit between the developing roller and the drum core, making the contact amount between the two unstable, easily causing wear of the drum core and insufficient page yield.

[0003] Therefore, in order to overcome the above-mentioned drawbacks, it is necessary to design an integrated toner cartridge with an automatic reset counting structure. Summary of the Utility Model

[0004] Aiming at the defects of the above-mentioned prior art, the utility model provides an integrated toner cartridge with an automatic reset counting structure, aiming to solve the problems of high operation complexity and time cost caused by manually resetting the counting gear when the toner cartridge is reused in the prior art, damage to the reusable toner cartridge and waste of resources caused by users' unfamiliarity with the disassembly and assembly principles of toner cartridges, and poor printing stability caused by loose fit due to repeated insertion and extraction of the toner cartridge and the drum frame.

[0005] To achieve the above object, the technical solution adopted by the present utility model is: An integrated toner cartridge with an automatic reset counting structure includes a toner cartridge body, and it further includes: a gear end face rotatably fitted with a counting gear at one end of the toner cartridge body; a gear end platform protruding from one side of the gear end face for positioning a drum driving gear integrally formed at the end of a drum core within the toner cartridge body; the counting gear includes a driving tooth and a reset extension tooth located on one side of the meshing end point of the driving tooth. The section between the meshing starting point and the meshing end point of the driving tooth is a release empty tooth section, and the section from the meshing starting point of the driving tooth clockwise to the meshing end point of the reset extension tooth is a reset empty tooth section. The driving tooth and the release empty tooth section are used for pressing and releasing a printer induction slider, and the outer diameter length of the reset empty tooth section is equal to the outer diameter arc distance by which an elastic member on the gear end face drives the counting gear to rotate.

[0006] Based on the above, the beneficial effects of an integrated toner cartridge with an automatic reset counting structure are as follows: It solves the problems in the prior art, including the high operation complexity and time cost caused by manually resetting the counting gear when the toner cartridge is reused, the damage of reusable toner cartridges and waste of resources caused by users' unfamiliarity with the disassembly and assembly principles of toner cartridges, and the poor printing stability caused by the loosening of the fit due to repeated plugging and unplugging of the toner cartridge and the drum frame; specifically reflected in:

[0008] 2. Through the design of the reset extension tooth, after the counting gear rotates to complete the printer recognition process, the intermediate gear continues to be in meshing with the reset extension tooth and continues to drive the counting gear to rotate synchronously until the reset empty tooth section reaches the meshing position with the intermediate gear, and the counting gear stops rotating; when the integrated toner cartridge is taken out of the printer, the push block follows the reset potential energy of the reset spring and leaves the limit strip on the counting gear, and the built-in elastic member is immediately activated and applies force to the mounting shaft, prompting the counting gear to rotate and reset.

[0041] A gear positioning plate 16 is positioned and fitted on the gear end face 1 through a positioning member. The gear ends of the developing roller 7 and the powder feeding roller 8 in the toner cartridge body are both positioned on the gear positioning plate 16.

[0047] In summary, the specific implementation of the present utility model is as follows: The user installs the integrated toner cartridge into the printer. At this time, the push block 104 on the integrated toner cartridge is squeezed by the inner wall of the printer and enters the push chute 101. The blocking rod 105 passes through the sliding hole 102 and blocks the rotation path of the limiting strip 53 on the outer end face of the counting gear 5, while the counting groove 17 is aligned and adapted to the induction dial of the printer. The driving teeth 51 of the counting gear 5 are pressed on the induction dial of the printer through the counting groove 17 to confirm the correct installation of the toner cartridge.

[0048] When the printer starts, the driving gear 11 starts to rotate, drives the counting gear 5 to rotate through the intermediate gear 15. The driving teeth 51 first press on the induction dial of the printer. As the counting gear 5 rotates, the driving teeth 51 disengage from the induction dial of the printer, and the empty tooth section 511 is released to reach the position of the induction dial of the printer to complete the release action. The counting gear 5 continues to rotate, and the driving teeth 51 press on the induction dial of the printer again to complete the machine recognition process.

[0049] After the machine recognition process is completed, the intermediate gear 15 continues to rotate. However, due to the existence of the reset extension tooth 52, the counting gear 5 does not stop immediately, but continues to rotate until the reset empty tooth section 521 is located at the meshing position of the intermediate gear 15, and then the counting gear stops.

[0050] While the counting gear 5 rotates, the elastic member 6 is squeezed by the arc-shaped convex portion 541, storing the energy required for reset. The elastic member 6 is preferably a torsion spring. The push block 104 on the gear side cover 10 is pressed into and slidably limited in the push chute 101 through the blocking rod 105 and the reset spring 106. The blocking rod passes through the sliding hole 102 and blocks the rotation path of the limiting strip 53 on the outer end face of the counting gear to prevent the counting gear from resetting.

[0051] After the toner is exhausted, the user takes out the integrated toner cartridge from the printer. At this time, the push block 104 pops out of the push chute 101 due to the action of the reset spring 106, releasing the block on the limiting strip 53 of the counting gear 5. The elastic member 6 releases the stored energy, drives the counting gear 5 to rotate through the arc-shaped convex portion 541 on the push mounting shaft 54 until the meshing starting point of the driving teeth 51 is aligned and meshed with the intermediate gear 15 to complete the reset and prepare for the next machine recognition process.

[0052] The above is only the optimal solution embodiment of the present utility model, and is not used to limit the present utility model. Various modifications or substitutions made by those skilled in the art to the present utility model without departing from the essence and protection scope of the present utility model should also be within the protection scope of the present utility model.
