Description

Technical Field

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

[0002] In the current printing technology field, traditional toner cartridges and drum frame assemblies 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 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 a 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 also 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.

[0003] Therefore, in order to overcome the above disadvantages, it is imperative to design a toner cartridge and a drum frame 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 a toner cartridge and a drum frame 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, as well as the damage of reusable toner cartridges and waste of resources caused by users' unfamiliarity with the disassembly and assembly principles of toner cartridges.

[0005] To achieve the above object, the technical solution adopted by the utility model is: a toner cartridge with an automatic reset counting structure, including a gear end, on which a counting gear meshing with a driving gear assembly is rotatably fitted. The counting gear includes a tooth-shaped part, and the tooth-shaped part includes a triggering tooth ring and an extended tooth. A printer recognition empty tooth section is arranged on the triggering tooth ring. The extended tooth is arranged on the side of the printer recognition empty tooth section away from the gear end and extends from the meshing end point of the triggering tooth ring. The triggering tooth ring and the printer recognition empty tooth section complete the printer recognition process by pressing and releasing a printer induction slider. The arc distance between the meshing end point of the extended tooth and the meshing starting point of the triggering tooth ring is a reset empty tooth section, and the arc distance of the reset empty tooth section is adapted to the outer diameter arc distance of the elastic member at the gear end driving the counting gear to rotate.

[0006] Based on the above, the beneficial effects of a toner cartridge and a drum frame with an automatic reset counting structure are as follows: It solves 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, as well as the problems of damage to the reusable toner cartridge and waste of resources caused by users' unfamiliarity with the disassembly and assembly principles of the toner cartridge; The main manifestations are as follows:

[0007] Through the design of the extended teeth in the present utility model, after the counting gear completes the machine recognition process, the driving gear assembly can continue to engage with the extended teeth. As the driving gear assembly rotates, the extended teeth of the counting gear also rotate accordingly until the reset empty tooth section rotates to the meshing position between the counting gear and the driving gear assembly, at which point the counting gear stops rotating; At the other end of the reset empty tooth section is the meshing starting point of the trigger tooth ring. When the anti-reset member leaves the blocking rib on the counting gear, the elastic member pushes the reset shaft to reset. This process drives the counting gear to rotate by squeezing the reset shaft. The length of the reset empty tooth section is designed to be equal to the rotational distance of the outer diameter of the counting gear during reset. Therefore, after the reset operation is completed, the meshing starting point of the trigger tooth ring can accurately engage with the driving gear assembly, thus realizing the automatic reset function;

[0008] The beneficial effect of the trigger tooth ring is to press the printer induction dial; The beneficial effect of the extended teeth is that after the counting gear completes the machine recognition process, the driving gear assembly can continue to engage with the extended teeth, causing the counting gear to stop rotating after rotating to the reset empty tooth section; The beneficial effect of the machine recognition empty tooth section is to release the printer induction dial; The beneficial effect of the reset empty tooth section is that after the reset operation is completed, the meshing starting point of the trigger tooth ring can accurately engage with the driving gear assembly.

[0009] Furthermore, the counting gear further includes a reset shaft, an extrusion member is arranged on the reset shaft, and a limiting platform is arranged on one side of the extrusion member, and the limiting platform is used to limit the elastic member within the extrusion member.

[0010] Based on the above, the beneficial effects of the reset shaft are as follows: enabling the elastic member to push the reset shaft to reset; The beneficial effect of the extrusion member is that the elastic member is extruded on the extrusion member to obtain the reset potential energy for the counting gear; The beneficial effect of the limiting platform is that the elastic member can be limited within the extrusion member to ensure the stability of the elastic member during the reset process.

[0011] Further, a gear side cover is externally fitted to the gear end. A resistance reset groove is provided on the gear side cover at the position of the counting gear. A resistance reset hole is provided in the middle of the resistance reset groove. Oblique platform fasteners are symmetrically arranged on both sides of the resistance reset hole. A resistance reset member is fitted in the resistance reset groove. Fastener chutes are provided at both ends of the resistance reset member. Limiting fasteners are provided on one side of each fastener chute close to the gear end. The oblique platform fasteners are slidably connected in the fastener chutes, and the sliding distance is limited by the limiting fasteners. A blocking rod is provided in the middle of the inner side of the resistance reset member. A reset spring is sleeved on the blocking rod, and the blocking rod passes through the resistance reset hole and blocks the rotation path of a blocking rib provided on the outer end face of the counting gear.

[0012] Based on the above, the beneficial effects of the gear side cover are to protect the drive gear assembly installed at the gear end and install the resistance reset member; the beneficial effect of the resistance reset groove is to install the resistance reset member; the beneficial effect of the resistance reset hole is to enable the blocking rod to pass through the resistance reset hole and block the rotation path of the blocking rib on the outer end face of the counting gear; the beneficial effect of the oblique platform fastener is to cooperate with the limiting fastener to limit and slidably install the resistance reset member in the fastener chute; the beneficial effect of the resistance reset member is to drive the blocking rod to block the rotation path of the blocking rib on the outer end face of the counting gear; the beneficial effect of the reset spring is that when the toner cartridge is taken out from the mounting bracket, it drives the resistance reset member to pop out, so that the blocking rib loses the blocking object and the counting gear is reset.

[0013] Further, the elastic member is a torsion spring structure. One end of the torsion spring structure is sleeved on a torsion spring positioning post on the gear end, and the other end is pressed against the pressing member.

[0014] Based on the above, the beneficial effect of the torsion spring structure is to be pressed against the pressing member to store the reset potential energy; the beneficial effect of the torsion spring positioning post is to install the torsion spring structure.

[0015] Further, an avoidance opening is provided at the lower end of the gear side cover on the side of the counting gear, and the counting gear is exposed outside the avoidance opening.

[0016] Based on the above, the beneficial effect of the avoidance opening is to enable the counting gear to be exposed outside the avoidance opening, which is convenient for the counting gear to contact with the printer sensing dialing member to complete the machine recognition action.

[0017] Further, the toner cartridge further includes a large-capacity powder bin and an integrated printing component. The large-capacity powder bin is arranged at the upper end of the integrated printing component, and a developing roller is arranged at the output end of the integrated printing component.

[0018] Further, the extended teeth are eight in shape.

[0019] A drum rack includes a photosensitive drum, a mounting bracket, and a toner cartridge. The photosensitive drum is installed on one side of the mounting bracket, and the toner cartridge is installed on the other side of the mounting bracket. Moreover, the developing roller at the output end of the toner cartridge is adapted to the photosensitive drum.

[0021] Further, an induction dialing member fitting port is provided at a position corresponding to the avoidance port on the mounting bracket, and the avoidance port is adapted above the induction dialing member fitting port.

[0022] Based on the above, the beneficial effect of the induction dialing member fitting port is to assist the drum rack in positioning the counting gear above the printer induction dialing member.

Detailed implementation manner

[0033] As Figures 1 - 8 shown, a toner cartridge with an automatic reset counting structure includes a gear end 1, a counting gear 4 rotatably fitted on the gear end 1 and meshing with a drive gear assembly 3. The counting gear 4 includes a tooth profile part 7. The tooth profile part 7 includes a trigger tooth ring 71 and an extended tooth 72. A machine recognition empty tooth section 711 is provided on the trigger tooth ring 71. The extended tooth 72 is arranged on a side of the machine recognition empty tooth section 711 away from the gear end 1 and extends from an engagement end point of the trigger tooth ring 71. The trigger tooth ring 71 and the machine recognition empty tooth section 711 complete the machine recognition process by pressing and releasing an induction dialing member of the printer. A return empty tooth section 721 is between an engagement end point of the extended tooth 72 and an engagement start point of the trigger tooth ring 71. An arc distance of the return empty tooth section 721 is adapted to an outer diameter arc distance by which an elastic member 5 of the gear end 1 drives the counting gear 4 to rotate.

[0034] The counting gear 4 further includes a return shaft 6. An extrusion member 61 is provided on the return shaft 6. A limit platform 62 is arranged on one side of the extrusion member 61. The limit platform 62 is used to limit the elastic member 5 in the extrusion member 61.

[0035] A gear end cover 2 is externally fitted to the gear end 1. A reset prevention groove 21 is provided on the gear end cover 2 at the position of the counting gear 2. A reset prevention hole 22 is provided in the middle of the reset prevention groove 21. Oblique platform fasteners 23 are symmetrically arranged on both sides of the reset prevention hole 22. A reset prevention member 24 is fitted in the reset prevention groove 21. Fastener sliding grooves 241 are provided at both ends of the reset prevention member 24. Limit fasteners 242 are provided on one side of the fastener sliding grooves 241 close to the gear end 1. The oblique platform fasteners 23 are slidably connected in the fastener sliding grooves 241 and are limited in sliding distance by the limit fasteners 242. A blocking rod 243 is provided in the middle of the inner side of the reset prevention member 24. A return spring 244 is sleeved on the blocking rod 243, and the blocking rod 243 passes through the reset prevention hole 22 and blocks the rotation path of a blocking rib 43 provided on the outer end face of the counting gear 4.

[0036] The elastic member 5 is a torsion spring structure. One end of the torsion spring structure is sleeved on a torsion spring positioning post 11 on the gear end 1, and the other end is pressed against the pressing member 61.

[0037] An avoidance opening 25 is provided at the lower end of the gear end cover 2 on one side of the counting gear 4. The counting gear 4 is exposed outside the avoidance opening 25.

[0038] The toner cartridge further includes a large-capacity powder bin 8 and an integrated printing assembly 9. The large-capacity powder bin 8 is arranged at the upper end of the integrated printing assembly 9. A developing roller 10 is provided at the output end of the integrated printing assembly 9.

[0039] The extended teeth 72 are in the shape of eight teeth.

[0040] A drum frame includes a photosensitive drum 100, a mounting bracket 200, and a toner cartridge. The photosensitive drum 100 is installed on one side of the mounting bracket 200. The toner cartridge is installed on the other side of the mounting bracket 200, and the developing roller 10 at the output end of the toner cartridge is adapted to the photosensitive drum 100.

[0041] One end of the mounting bracket 200 presses the reset prevention member 24 in the reset prevention groove 21.

[0042] An induction dialing member fitting port 201 is provided on the mounting bracket 200 at a position corresponding to the avoidance opening 25, and the avoidance opening 25 is adapted above the induction dialing member fitting port 201.

[0043] In summary, the specific implementation of the present utility model is as follows: The user loads the toner cartridge onto the mounting bracket 200 and makes the developing roller 10 cooperate with the photosensitive drum 100 on the mounting bracket. At this time, the blocking and resetting member 24 on the toner cartridge is squeezed into the blocking and resetting groove 21 by the inner side of the end face of the mounting bracket 200, and the blocking rod 243 passes through the blocking and resetting hole 22 and blocks on the rotation path of the blocking rib 43 on the outer end face of the counting gear 4. The user installs the entire drum frame into the printer. The induction dialing member mating port 201 of the mounting bracket 200 is adapted to the printer induction dialing member, and the counting gear 4 is exposed outside the avoidance port 25 and presses on the printer induction dialing member to enable the printer to confirm that the drum frame is installed;

[0044] When the printer is started, the drive gear assembly 3 rotates, driving the counting gear 4 to rotate. The trigger tooth ring 71 of the counting gear 4 presses on the printer induction dialing member. As the counting gear 4 rotates, the trigger tooth ring 71 leaves the printer induction dialing member, and the machine recognition empty tooth section 711 reaches the position of the printer induction dialing member, that is, the printer induction dialing member is released. As the counting gear 4 continues to rotate, the trigger tooth ring 71 presses on the printer induction dialing member again to complete the "machine recognition" process;

[0045] After the machine recognition process, the drive gear assembly 3 continues to rotate. Due to the existence of the extended tooth 72, the counting gear 4 will not stop after the machine recognition empty tooth section 711 enters the original meshing position between the trigger tooth ring 71 and the drive gear assembly 3. The drive gear assembly 3 will continue to mesh with the extended tooth 72 to make the counting gear 4 continue to rotate until the reset empty tooth section 721 reaches the meshing position of the drive gear assembly 3, at which time the counting gear stops rotating;

[0046] While the counting gear 4 is rotating, the elastic member 5 is squeezed by the squeezing member 61 to store the energy required for resetting. The blocking and resetting member 24 on the gear side cover 2 is pressed into and slidably limited in the blocking and resetting groove 21 through the blocking rod 243 and the reset spring 244. The blocking rod passes through the blocking and resetting hole 22 and blocks on the rotation path of the blocking rib 43 on the outer end face of the counting gear to prevent the counting gear from resetting;

[0047] After the toner is exhausted, the user takes out the drum frame from the printer and then takes out the toner cartridge from the drum frame. At this time, due to the action of the reset spring 244, the blocking and resetting member 24 pops out from the blocking and resetting groove 21, so that the blocking rod 243 no longer blocks the blocking rib 43 of the counting gear 4. The elastic member 5 releases the stored energy, pushes the squeezing member 61 on the reset shaft 6, and drives the counting gear to rotate. The counting gear 4 rotates the length of the reset empty tooth section 721 until the meshing starting point of the trigger tooth ring 71 is aligned and meshed with the drive gear assembly 3 to complete the reset. At this time, the trigger tooth ring 71 is ready for the next "machine recognition" process.

[0048] 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.
