Description

Technical Field

[0001] This utility model relates to the technical field of toner cartridge devices, and in particular to a toner cartridge device that is easy to add toner. Background Technology

[0002] The toner cartridge is a core component in office equipment such as laser printers and copiers. It is mainly used to complete the printing process of "electrostatic imaging-toner transfer-fixing". When the device receives the print data, the laser scanning system converts the image information into a laser beam and irradiates the surface of the photosensitive drum. After printing, excess toner and charge may remain on the surface of the toner cartridge. The cleaning device (such as a cleaning blade or charge elimination device) will remove the residual toner and eliminate the residual charge on the surface of the photosensitive drum, restoring it to its initial state.

[0003] In existing toner cartridge devices, which facilitate the addition of toner, it is inconvenient to dispense toner quantitatively. Users cannot intuitively judge the "remaining toner amount" or "the amount to be added". In most cases, they can only judge by indirect signals such as the print quality becoming faint or the device indicating that the toner is low. Adding toner relies on experience to estimate, which has a large error. Therefore, a toner cartridge device that facilitates the addition of toner is provided. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides the following technical solution: a toner cartridge device for easy toner addition, comprising: a toner cartridge device, a motor connected to one side of the toner cartridge device, a pulley connected to one end of the motor, a lead screw connected to the end of the pulley away from the motor, a slider passing through the lead screw, a horizontal plate fixedly connected to the top of the slider, four corner limiting plates connected to the end of the horizontal plate away from the slider, grooves connected to both sides of the four corner limiting plates, baffles fixedly connected to the bottom of the grooves, a circular tube provided in the middle of the four corner limiting plates, and a funnel fixedly connected to the top of the circular tube.

[0005] As an improvement to the above technical solution, the output end of the motor is connected to a rotating shaft, a positioning shaft is fixedly connected to the periphery of the rotating shaft, and a plurality of stirring rods are fixedly connected to the periphery of the positioning shaft.

[0006] As an improvement to the above technical solution, a bracket is provided at the bottom of the motor, and one end of the bracket is fixedly connected to one side of the outer wall of the toner cartridge device.

[0007] As an improvement to the above technical solution, a limiting block is fixedly connected to one side of the inner wall of the toner cartridge device, and the end of the rotating shaft away from the motor is rotatably connected inside the limiting block.

[0008] As an improvement to the above technical solution, the lead screw passes through a fixing plate, and the end of the fixing plate away from the lead screw is fixedly connected to one side of the outer wall of the toner cartridge device.

[0009] As an improvement to the above technical solution, a vertical plate is fixedly connected to one side of the slide, and the end of the vertical plate away from the slide is fixedly connected to the top of the baffle.

[0010] As an improvement to the above technical solution, a number of positioning plates are fixedly connected to the bottom end of the baffle, and the number of positioning plates are fixedly connected to the top end of the toner cartridge device.

[0011] As an improvement to the above technical solution, a gravity sensor is provided on one side of the bottom end of the baffle, and a protective box is provided around the gravity sensor, with the protective box fixedly connected to the bottom end of the baffle.

[0012] As an improvement to the above technical solution, a feed inlet is provided on one side of the top of the drum unit, and a rubber sealing ring is provided at the junction of the feed inlet and the drum unit.

[0013] As an improvement to the above technical solution, a connecting plate is provided at the junction of the four corner limiting plates and the horizontal plate.

[0014] The beneficial effects of this utility model are as follows: A motor is used as the power source, rotating to drive a pulley, thus achieving mechanical transmission power input. The pulley transmits the motor power to the lead screw, causing it to rotate. During the rotation of the lead screw, the slider moves. A horizontal plate connects the slider and the four corner limiting plates, facilitating the synchronous movement of the cylindrical tube and funnel during the slider's movement. Because the shape of the cylindrical tube and funnel is fixed, the amount of toner stored each time is consistent, facilitating subsequent dispensing. When toner falls into the cylindrical tube and funnel, the gravity sensor sends a signal. When the controller receives the signal, it triggers a signal to control the lead screw, which in turn moves the cylindrical tube and funnel, ensuring consistent toner weight each time. The protective box protects the gravity sensor. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0022] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0023] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0024] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0025] See appendix Figure 1-4 As shown, to solve the above problems, a toner cartridge device that facilitates toner addition is provided, comprising: a toner cartridge device 1, a motor 2 connected to one side of the toner cartridge device 1, a pulley 3 connected to one end of the motor 2, a lead screw 5 connected to the end of the pulley 3 away from the motor 2, a slider 6 passing through the lead screw 5, a horizontal plate 7 fixedly connected to the top of the slider 6, a four-corner limiting plate 23 connected to the end of the horizontal plate 7 away from the slider 6, a sliding groove 11 connected to both sides of the four-corner limiting plate 23, a baffle 12 fixedly connected to the bottom of the sliding groove 11, a round tube 9 provided in the middle of the four-corner limiting plate 23, and a funnel 10 fixedly connected to the top of the round tube 9.

[0026] The motor 2 serves as the power source, rotating to drive the pulley 3, thus providing mechanical power input. The pulley 3 transmits power from the motor 2 to the lead screw 5, causing the lead screw 5 to rotate. During the rotation of the lead screw 5, the slider 6 can move. The horizontal plate 7 connects the slider 6 and the four corner limiting plates 23, facilitating the synchronous movement of the circular tube 9 and the funnel 10 as the slider 6 moves. Since the shapes of the circular tube 9 and the funnel 10 are fixed, the amount of toner stored each time is consistent, facilitating subsequent dispensing. Under the action of the four corner limiting plates 23 and the slide groove 11, a "guide rail-limiting" structure is formed, restricting the movement direction of the circular tube 9 and the funnel 10 and preventing deviation.

[0027] For specific implementation details, please refer to [link / reference]. Figure 1-4 Specifically, the output end of motor 2 is connected to a rotating shaft 15, a positioning shaft 16 is fixedly connected to the periphery of the rotating shaft 15, and several stirring rods 18 are fixedly connected to the periphery of the positioning shaft 16.

[0028] The rotating shaft 15 is driven to rotate by the motor 2. The rotating shaft 15 and the stirring rod 18 can be connected together by the positioning shaft 16. This allows the stirring rod 18 to rotate synchronously during the rotation of the rotating shaft 15, which facilitates the rotation of the stirring rod 18 and makes it easier to stir the toner inside the drum unit 1, thus preventing the toner from sticking together.

[0029] For specific implementation details, please refer to [link / reference]. Figure 1-4 Specifically, a bracket 19 is provided at the bottom of the motor 2, and one end of the bracket 19 is fixedly connected to one side of the outer wall of the toner cartridge device 1.

[0030] A rubber buffer pad may be added to the contact area between the bracket 19 and the motor 2 to reduce the transmission of motor 2 vibration to the drum body and avoid affecting the operating accuracy of precision components such as the photosensitive drum.

[0031] For specific implementation details, please refer to [link / reference]. Figure 1-4 Specifically, a limiting block 17 is fixedly connected to one side of the inner wall of the toner cartridge device 1, and the end of the rotating shaft 15 away from the motor 2 is rotatably connected inside the limiting block 17.

[0032] One end of the rotating shaft 15 is driven by the output shaft of the motor 2, and the other end is inserted into the bearing hole of the limiting block 17 to form a "two-point support" structure, which prevents the rotating shaft 15 from shifting during rotation and causing the equipment to collide.

[0033] For specific implementation details, please refer to [link / reference]. Figure 1-4 Specifically, the lead screw 5 passes through the fixing plate 4, and the end of the fixing plate 4 away from the lead screw 5 is fixedly connected to one side of the outer wall of the toner cartridge device 1.

[0034] By using the fixing plate 4, a mounting position can be provided for the lead screw 5, and the axial rotation of the lead screw 5 can be restricted, so as to prevent the lead screw 5 from deviating during rotation, which would cause the slider 6 to move in a deviated direction and affect the subsequent use effect.

[0035] For specific implementation details, please refer to [link / reference]. Figure 1-4 Specifically, a vertical plate 13 is fixedly connected to one side of the slide 11, and the end of the vertical plate 13 away from the slide 11 is fixedly connected to the top of the baffle 12.

[0036] By using the vertical plate 13, the chute 11 and the baffle 12 can be connected together, making the circular tube 9 and the funnel 10 more stable during movement and facilitating the subsequent addition of toner.

[0037] For specific implementation details, please refer to [link / reference]. Figure 1-4 Specifically, the bottom end of the baffle 12 is fixedly connected to several positioning plates 14, and the several positioning plates 14 are fixedly connected to the top end of the toner cartridge device 1.

[0038] The baffle 12 is fixedly connected to the top of the toner cartridge 1 via the positioning plate 14, forming the reference positioning structure of the entire toner filling mechanism.

[0039] For specific implementation details, please refer to [link / reference]. Figure 1-4 Specifically, a gravity sensor 21 is provided on one side of the bottom of the baffle 12, and a protective box is provided around the gravity sensor 21. The protective box is fixedly connected to the bottom of the baffle 12.

[0040] When toner falls into the tube 9 and the funnel 10, the gravity sensor 21 sends a signal. When the controller receives the signal, it will cause the motor 2 to control the lead screw 5 to work, thereby pushing the tube 9 and the funnel 10 to move, so that the weight of toner added each time is consistent. The protective box can protect the gravity sensor 21.

[0041] For specific implementation details, please refer to [link / reference]. Figure 1-4 Specifically, a feed inlet 22 is located on one side of the top of the drum unit 1, and a rubber sealing ring is provided at the junction of the feed inlet 22 and the drum unit 1.

[0042] The rubber sealing ring achieves three functions: preventing powder leakage, controlling dust, and maintaining air pressure. Its specific function can be seen from the sealing mechanism, and the feed inlet 22 facilitates the delivery of toner into the equipment.

[0043] For specific implementation details, please refer to [link / reference]. Figure 1-4 Specifically, a connecting plate 8 is connected at the junction of the four corner limiting plates 23 and the horizontal plate 7.

[0044] The four corner limiting plates 23 can avoid stress concentration problems caused by individual connections, enhance the tensile and shear resistance of the joint, and prevent cracking or loosening under stress.

[0045] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the present utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of the present utility model, thereby enabling those skilled in the art to better understand and utilize it. The present utility model is limited only by the claims and their full scope and equivalents.
