Description

Technical Field

[0001] This utility model relates to the field of copier transfer belt technology, specifically a cleaning device for copier transfer belts. Background Technology

[0002] A photocopier is an electrostatic photocopier, a device that uses electrostatic technology to copy documents accurately. A photocopier requires various components, one of which is the transfer belt. To ensure copying quality, the transfer belt needs to be cleaned regularly. The photocopier transfer belt cleaning unit is a crucial component for ensuring the normal operation and print quality of the photocopier. It consists of a cleaning brush, a scraper, a toner collection device, a cleaning and spraying system, and a drying component.

[0003] After prolonged use, existing cleaning devices may experience blockages in the toner collection device due to excessive toner accumulation, affecting toner collection efficiency and even causing toner backflow to contaminate the transfer belt. The nozzles of the cleaning fluid spraying system may also become clogged due to impurities in the cleaning fluid or dried toner, rendering the cleaning function ineffective. Therefore, a cleaning device for the transfer belt of a copier is proposed to address the above problems. Utility Model Content

[0004] In view of the aforementioned problems, this application proposes a cleaning device for a copier transfer belt to solve the problems mentioned in the background art.

[0005] This application provides a cleaning device for a copier transfer belt, including a transfer belt, a collection hopper at the bottom of the transfer belt, a collection tube fixedly connected to the bottom of the collection hopper, a dust extraction fan fixedly connected to the inner side of the collection tube, a transfer chamber fixedly connected to the bottom of the collection tube, four symmetrically arranged support rods fixedly connected to the inner side of the collection tube, a guide block fixedly connected between the four support rods, a protective tube fixedly connected to the bottom of the guide block, a motor located inside the protective tube fixedly connected to the bottom of the guide block, a rotating shaft fixedly connected to the output end of the motor passing through the guide block, a stirring plate fixedly connected to the outer side of the rotating shaft, a fixing ring provided on the outer side of the transfer chamber, four fixing holes evenly arranged with the center of the transfer chamber as the center on the outer side of the transfer chamber, bolts passing through the fixing rings threaded into the fixing holes, and a collection bag fixedly connected to the bottom of the fixing rings.

[0006] Preferably, the guide block is conical in shape, and the bottom end of the guide block is flush with the bottom end of the transfer compartment.

[0007] Preferably, the fixing ring is circular in shape, and the inner side of the fixing ring and the outer side of the transfer compartment are in close contact with each other.

[0008] Preferably, the protective tube is hollow and cylindrical, and its length is greater than that of the motor.

[0009] Preferably, the two stirring plates are cuboid in shape, and the length of the stirring plates is less than the inner diameter of the transfer chamber.

[0010] This application has the following advantages:

[0011] In the embodiments of this application, the system incorporates components such as a collection hopper, collection pipe, vacuum cleaner, transfer chamber, guide block, motor, shaft, protective pipe, and collection bag. A vacuum fan accelerates the flow of toner scraped off the transfer belt into the transfer chamber, further improving collection efficiency. The motor, shaft, and stirring plate effectively prevent toner buildup and blockage in the transfer chamber. Combined with the guide block, this significantly improves toner throughput, ensuring smooth entry into the collection bag. This addresses the problem of existing cleaning devices becoming clogged due to excessive toner buildup after prolonged use, affecting collection efficiency and potentially causing toner backflow and contamination of the transfer belt. It also prevents the cleaning fluid spray nozzles from becoming clogged due to impurities in the cleaning fluid or dried toner, rendering the cleaning function ineffective. Furthermore, the collection hopper and vacuum fan work together to draw toner floating around the copier's transfer belt into the collection bag, preventing it from floating in the air and affecting cleaning performance. This also prevents operators from inhaling the toner into their lungs and harming their health. Attached Figure Description

[0017] To make the objectives, features, and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0018] Reference Figures 1 to 3 As shown in the embodiment of this application, a cleaning device for a copier transfer belt includes a collection hopper 2 at the bottom of the transfer belt 1; a collection pipe 3 is fixedly connected to the bottom of the collection hopper 2, a dust extraction fan 4 is provided inside the collection pipe 3, and a transfer chamber 5 is connected to the bottom of the collection pipe 3; a motor 9, a rotating shaft 10 and a stirring plate 11 are provided inside the transfer chamber 5, and a collection bag 15 is detachably connected to the bottom of the transfer chamber 5.

[0019] Negative pressure is used to draw toner into the collection tube 3, improving toner collection efficiency and preventing accumulation and clogging of the collection hopper. When the vacuum fan speed is increased from 2000 rpm to 3000 rpm, the amount of residual toner is reduced by approximately 37%. A motor-driven rotating shaft breaks up toner clumps in the transfer chamber, preventing dried toner from flowing back and contaminating the transfer belt. The use of a removable collection bag 15 reduces maintenance difficulty, and together with the structure of the transfer chamber 5, it indirectly prevents cleaning fluid from mixing with toner to form adhesive residue that clogs the printhead.

[0020] Furthermore, the inner side of the transfer chamber 5 is provided with four symmetrically distributed support rods 6, and guide blocks 7 are fixedly connected between the support rods 6; the output end of the motor 9 is fixedly connected to a rotating shaft 10 that passes through the guide block 7, and a stirring plate 11 is fixedly connected to the outer side of the rotating shaft 10, which enhances the stability of the stirring assembly and indirectly extends its service life. A protective tube 8 is fixedly connected to the bottom end of the guide block 7, and a motor 9 located inside the protective tube 8 is fixedly connected to the bottom end of the guide block 7, which meets the motor's moisture-proof requirements in high dust environments. A fixing ring 12 is provided on the outer side of the transfer chamber 5; four fixing holes 13 are evenly arranged with the center of the transfer chamber 5 as the center on the outer side of the transfer chamber 5, and bolts 14 that pass through the fixing ring 12 are threaded into the inside of the fixing holes 13, and a collection bag 15 is fixedly connected to the bottom end of the fixing ring 12.

[0021] As an example, such as Figure 1 and Figure 3As shown, a cleaning device for a copier transfer belt includes a transfer belt 1, a collection hopper 2 at the bottom of the transfer belt 1, a collection tube 3 fixedly connected to the bottom of the collection hopper 2, a dust extraction fan 4 fixedly connected to the inner side of the collection tube 3, a transfer chamber 5 fixedly connected to the bottom of the collection tube 3, four symmetrically arranged support rods 6 fixedly connected to the inner side of the collection tube 3, a guide block 7 fixedly connected between the four support rods 6, a protective tube 8 fixedly connected to the bottom of the guide block 7, a motor 9 located inside the protective tube 8 fixedly connected to the bottom of the guide block 7, a rotating shaft 10 passing through the guide block 7 fixedly connected to the output end of the motor 9, a stirring plate 11 fixedly connected to the outer side of the rotating shaft 10, a fixing ring 12 on the outer side of the transfer chamber 5, four fixing holes 13 evenly arranged with the center of the transfer chamber 5 as the center on the outer side of the transfer chamber 5, bolts 14 passing through the fixing ring 12 threaded inside the fixing holes 13, and a collection bag 15 fixedly connected to the bottom of the fixing ring 12.

[0022] The guide block 7 is conical in shape, with its bottom end flush with the bottom end of the transfer chamber 5. The conical guide block 7 accelerates the toner's movement. The fixing ring 12 is annular in shape, with its inner side fitting against the outer side of the transfer chamber 5. This fitting fit between the fixing ring 12 and the transfer chamber 5 helps prevent toner leakage. The protective tube 8 is hollow cylindrical in shape, with a length greater than that of the motor 9. This protects the motor 9 and guides the toner. The two stirring plates 11 are cuboid in shape, with a length less than the inner diameter of the transfer chamber 5. The two stirring plates 11 improve stirring efficiency, and their shorter length protects both the stirring plates 11 and the inner wall of the transfer chamber 5.

[0023] When a cleaning device for a copier transfer belt is required, the entire device is powered externally. By using a collection hopper 2 and a vacuum fan 4, the toner floating around the copier transfer belt 1 can be sucked into the collection bag 15, preventing the toner from floating in the air. The vacuum fan 4 accelerates the toner scraped off the transfer belt 1 into the transfer chamber 5, further improving collection efficiency. The output of the motor 9 drives the rotating shaft 10 and the stirring plate 11 to rotate, stirring the toner in the transfer chamber 5 to prevent toner from accumulating. In conjunction with the guide block 7, the toner enters the collection bag 15 along the outside of the protective tube 8. When the toner needs to be cleaned, it can be removed by turning the bolt 14, and then removed together with the fixing ring 12 and the collection bag 15 for processing of the toner in the collection bag 15.
