Description

Technical Field

[0001] The utility model relates to the technical field of carbon powder boxes, in particular to a toner cartridge structure with integrated toner and drum. Background Art

[0002] Existing toner cartridges generally adopt a split drum frame and toner cartridge structure, in which independent slots need to be opened on the surface of the drum frame and the toner cartridge respectively, and the drum frame chip and the powder bin chip are fixed by screws. This structure leads to a large number of parts and a complicated assembly process. During installation, the chip connection nodes on the top and bottom of the printer need to be aligned at the same time, which can easily cause poor chip contact due to positioning deviation. The design of traditional chips directly contacting the metal contacts of the printer has obvious defects. Friction loss during long-term use can easily cause contact wear, and the risk of signal transmission failure is high. The split structure of the drum frame and toner cartridge connection lacks an effective positioning mechanism. It only relies on a simple toner cartridge buckle to fix it in the drum frame, which can easily lead to assembly misalignment, causing the chip installation position to shift, affecting the printer's accurate identification of the toner residue.

[0003] Therefore, the inventor redesigned a toner cartridge structure with integrated drum and powder to solve the above problems. Utility Model Content

[0004] In view of the defects of the prior art, the utility model provides a toner cartridge structure with integrated drum and toner, aiming to solve the problems of complex assembly and poor chip contact caused by the separate drum frame and toner cartridge structure in the prior art.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a toner cartridge structure with integrated drum and powder, including a powder bin and a waste powder bin, wherein preliminary nesting columns are provided at both ends of the powder bin close to the upper edge on one side of the waste powder bin, and preliminary nesting grooves matching the preliminary nesting columns are provided at the corresponding positions of the waste powder bin, so as to complete the preliminary positioning of the powder bin and the waste powder bin; a drum rack chip mounting frame is provided at the upper end of the waste powder bin, and chip sliding structures are respectively provided on the upper and lower walls of the inner cavity of the drum rack chip mounting frame, and a drum rack chip is slidably matched between the two groups of the chip sliding structures; A plurality of metal sheet mounting grooves are evenly arranged on the upper end surface of the drum rack chip mounting frame, and a metal sheet is arranged in the metal sheet mounting groove. A snap-fit ​​structure is arranged at the end of the metal sheet mounting groove away from the powder bin, and one end of the metal sheet is snap-fitted to the snap-fit ​​structure; a metal sheet insertion hole is arranged at the end of the metal sheet mounting groove close to the powder bin, and the other end of the metal sheet passes through the metal sheet insertion hole; an L-shaped limiter is arranged at the upper end of the interior of the drum rack chip mounting frame away from the powder bin side, and the L-shaped limiter crimps the metal sheet passing through the metal sheet insertion hole onto the surface of the drum rack chip.

[0006] Based on the above, the beneficial effect of a toner cartridge structure with integrated drum and toner is to solve the problem of complex assembly and poor chip contact caused by the split drum frame and toner cartridge structure in the prior art; it is mainly reflected in:

[0007] 1. The utility model realizes the rapid positioning between the powder bin and the waste powder bin through the preliminary nesting columns and preliminary nesting grooves on the powder bin and the waste powder bin, which greatly simplifies the assembly process. In addition, the drum frame chip is installed in the drum frame chip mounting frame through the chip sliding structure sliding fit, and the powder bin chip is installed in the powder bin chip slot through the powder bin chip positioning ribs and the powder bin chip positioning point block. The need for screw fixing is reduced, and the assembly complexity is reduced;

[0008] 2. One end of the metal sheet of the utility model is fixed in the metal sheet mounting groove by a snap-fit ​​structure, and the other end passes through the metal sheet insertion hole and is elastically crimped on the surface of the drum frame chip through an L-shaped limiter, ensuring a stable connection of the drum frame chip. The metal contacts on the external contact sheet of the powder bin chip are elastically connected to the powder bin chip through a guide sheet, avoiding the wear problem caused by traditional hard contact and enhancing the reliability of signal transmission.

[0009] Furthermore, the two ends of the powder bin and the waste powder bin are respectively provided with gear end covers and conductive end covers, a powder bin chip mounting frame is provided at the bottom of the gear end cover, a powder bin chip slot is provided on the end of the powder bin chip mounting frame away from the waste powder bin, powder bin chip positioning ribs are respectively provided at the upper and lower ends of the powder bin chip slot near the outer end of the gear end cover, a number of powder bin chip positioning point blocks are respectively provided at intervals in the middle of the powder bin chip slot near the inner end of the gear end cover, the two powder bin chip positioning ribs in the powder bin chip slot and the number of powder bin chip positioning point blocks are jointly slidably limited with the powder bin chip; a powder bin chip external contact sheet is provided at the bottom end of the powder bin chip mounting frame, and the metal contacts on the powder bin chip external contact sheet are elastically contacted and connected with the powder bin chip through the guide sheet through the gap between every two powder bin chip positioning point blocks.

[0010] Based on the above, the beneficial effect of the powder bin chip slot is to realize the sliding limit cooperation of the powder bin chip; the beneficial effect of the external contact piece of the powder bin chip being elastically contacted and connected with the powder bin chip through the guide piece is to avoid the wear problem that may be caused by traditional hard contact, and also enhance the stability and reliability of signal transmission, and reduce the risk of contact failure caused by friction loss.

[0011] Furthermore, a plurality of positioning posts are distributed at both ends of the powder bin and the waste powder bin, and a plurality of positioning holes of the gear end cover and the conductive end cover are respectively matched with the corresponding positioning posts.

[0012] Based on the above, the beneficial effect of the cooperation between the positioning column and the positioning hole is to ensure that during the assembly process, the gear end cover and the conductive end cover can be accurately installed to the designated positions of the powder bin and the waste powder bin, greatly improving the accuracy and consistency of the overall assembly and reducing problems caused by assembly errors.

[0013] Furthermore, an elastic barb inclined inwardly is provided on one side of the metal sheet close to the buckle structure, and one end of the metal sheet inserted into the metal sheet insertion hole is elastically pressed against the contact area of ​​the drum frame chip by the L-shaped limiting member.

[0014] Based on the above, the beneficial effect of the elastic barb is that when the metal sheet is inserted into and fixed in the metal sheet mounting groove, the elastic barb can cooperate closely with the snap-on structure to ensure that the metal sheet will not loosen or fall off easily, thereby enhancing the stability and reliability of the connection; the beneficial effect of the L-shaped limiter elastically crimped on the contact area of ​​the drum rack chip is that it ensures good contact between the metal sheet and the drum rack chip, and also provides additional mechanical support to prevent poor contact problems caused by external vibration or other external forces, thereby improving the reliability and stability of the overall assembly.

[0015] Furthermore, the powder bin chip positioning point blocks are convex structures distributed at intervals, and the distance between adjacent powder bin chip positioning point blocks is greater than or equal to the width of the guide piece, forming a guiding constraint on the guide piece.

[0016] Based on the above, the beneficial effect of the powder bin chip positioning point block is to limit the position of the powder bin chip and effectively constrain the guide plate, thereby avoiding the guide plate from offsetting or loosening during use and reducing poor contact problems caused by position deviation.

[0017] Furthermore, threaded hollow columns are distributed at both ends of the powder bin and the waste powder bin. After the powder bin and the waste powder bin are initially positioned through the initial nesting columns and the initial nesting grooves, the gear end cover and the conductive end cover are aligned with the threaded hollow columns through the end cover screw holes thereon and then fixedly connected with screws.

[0018] Based on the above, the beneficial effect of using screws to fix the gear end cover and the conductive end cover after the end cover screw holes are aligned with the threaded hollow column is to ensure the tight connection between the gear end cover and the conductive end cover to the powder bin and the waste powder bin, enhance the stability and firmness of the overall structure, and prevent loosening or displacement caused by vibration or external force during use.

[0019] Furthermore, a plurality of conductive plastic sheets are arranged on the conductive end cover.

[0020] Based on the above, after the conductive plastic sheet replaces the traditional metal conductive sheet, it can contact the printer contacts more flexibly, avoiding the problem of unstable signal transmission caused by hard contact of the metal sheet, and improving the reliability of signal transmission. The conductive plastic sheet has better wear resistance and elasticity, which can effectively reduce the friction loss between the printer contacts, thereby extending the service life of the toner cartridge and reducing the risk of failure due to contact wear.
