Description

Technical Field

[0001] This utility model relates to the technical field of printer consumable filling equipment, specifically a toner filling device. Background Technology

[0002] In the field of maintenance and consumable replenishment of office equipment such as printers and copiers, toner refilling is a crucial step.

[0003] The existing patent document CN221938518U discloses a toner filling device. This utility model utilizes a rolling assembly. During toner filling, when the toner is inside the toner can and falls into the toner trough, a drive motor drives a transmission mechanism to rotate the roller inside the toner can. When the toner trough rotates to the bottom, the toner inside the trough falls into the sleeve. Since the diameter and height of the roller are consistent with the width and length of the toner can, the toner can only be filled through the toner trough, which facilitates the control of the toner filling volume.

[0004] However, existing toner filling devices are not convenient for automatically cleaning toner adhering to the inner walls of the device. When toner continues to accumulate on the inner walls of the material bin and feed hopper, it gradually changes the geometric contour of the cavity, causing the toner flow path to deviate. This directly affects the precise control of the filling amount. More seriously, residual toner is prone to solidification reaction when it comes into contact with moisture in the air, forming hard lumps. This not only greatly increases the difficulty of cleaning operations, but may also mix in new toner during subsequent filling processes, resulting in quality defects such as spots and background gray in the printed output. Currently, devices generally rely on manual disassembly of the material bin for wiping and cleaning. This process is not only time-consuming and labor-intensive, but frequent disassembly and assembly also causes accelerated wear and tear on components, further increasing the maintenance cost of the device. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] The purpose of this invention is to provide a toner filling device to solve the problem mentioned in the background art that existing toner filling devices are not convenient for automatically cleaning the toner adhering to the inner wall of the device.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, the present invention provides the following technical solution: a toner filling device, including a U-shaped support base, a material hopper is provided above the U-shaped support base, a conical guide hopper integrally formed with the bottom end of the material hopper extends from the material hopper, and a drive motor is installed in the middle of the upper surface of the material hopper;

[0009] The drive end of the drive motor is fixedly connected to a screw conveyor shaft through the material bin. Multiple connecting rods are connected to the outer surface of the screw conveyor shaft. The ends of the connecting rods away from the screw conveyor shaft are respectively connected to a first scraper and a second scraper. The first scraper is in contact with the inner wall of the cylindrical section of the material bin, and the second scraper is in contact with the inner wall of the conical guide hopper of the material bin. Both the first and second scrapers are coated with an anti-stick coating.

[0010] As a further improvement to the above solution, a fixing plate is vertically arranged on the upper surface of the U-shaped support base, and an electric push rod is installed on one side of the vertical section of the U-shaped support base.

[0011] As a further improvement to the above solution, the transmission end of the electric push rod is fixedly connected to a push rod through the U-shaped support base, and a movable clamp is fixedly connected to the end of the push rod away from the electric push rod.

[0012] As a further improvement to the above solution, rubber pads are embedded on the opposite surfaces of the movable clamping plate and the fixed clamping plate, and the top of the inner side of the U-shaped support base spans the fixed bracket.

[0013] As a further improvement to the above solution, an adjustment motor is installed on one side inside the fixed bracket, and an adjustment screw is fixedly connected to the transmission end of the bottom of the adjustment motor. The end of the adjustment screw away from the adjustment motor is connected to the fixed bracket through a bearing.

[0014] As a further improvement to the above solution, the outer surface of the adjusting screw is connected to an adjusting screw block by a thread, and the adjusting screw block is in sliding engagement with the fixed bracket.

[0015] As a further improvement to the above solution, a lifting cylinder is installed at the bottom of the adjusting screw block, and a support frame is fixedly connected to the transmission end of the bottom of the lifting cylinder. The material bin is disposed through the middle of the support frame.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This toner filling device, by coating the surfaces of scraper No. 1 and scraper No. 2 with an anti-stick coating, and in conjunction with the rotation of the screw conveyor shaft, makes it difficult for toner to adhere to the inner wall of the material bin and the conical guide hopper during conveying. This avoids the clogging problem caused by toner residue agglomeration in traditional devices, reduces the frequency of cleaning and maintenance, ensures continuous and stable toner conveying, and improves toner conveying efficiency.

[0018] 2. This toner filling device uses an electric push rod to drive the movable clamping plate to cooperate with the fixed clamping plate. With the help of the elastic buffer of the rubber pad, it can automatically adapt to different specifications of toner cartridges and achieve precise positioning. At the same time, the anti-slip texture on the surface of the rubber pad increases the clamping friction, prevents the toner cartridge from shifting or shaking during filling, and ensures stable filling operation.

[0019] 3. This toner filling device uses a motor to drive an adjusting screw to slide horizontally, and a lifting cylinder to adjust vertically, allowing the conical guide hopper outlet to quickly align with the toner cartridge filling port. Through optimized mechanical structure, it achieves rapid adjustment and precise positioning of the filling position, significantly improving operating efficiency and positioning accuracy compared to traditional manual adjustment.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1 - Figure 4 This utility model provides a technical solution: a toner filling device, including a U-shaped support base 1, a material bin 2 is provided above the U-shaped support base 1, a conical guide hopper 3 integrally formed with the bottom end of the material bin 2 extends out, and a drive motor 4 is installed in the middle of the upper surface of the material bin 2.

[0027] The drive end of the drive motor 4 passes through the material bin 2 and is fixedly connected to the screw conveyor shaft 5. Multiple connecting rods 6 are connected to the outer surface of the screw conveyor shaft 5. The end of the connecting rod 6 away from the screw conveyor shaft 5 is respectively connected to the first scraper 7 and the second scraper 8. The first scraper 7 is in contact with the inner wall of the cylindrical section of the material bin 2, and the second scraper 8 is in contact with the inner wall of the conical guide hopper 3 of the material bin 2. The surfaces of the first scraper 7 and the second scraper 8 are both coated with an anti-stick coating.

[0028] The drive motor 4 starts working, driving the screw conveyor shaft 5 to rotate, pushing the toner in the material bin 2 through the conical guide hopper 3 into the toner drum. During the rotation of the screw conveyor shaft 5, the connecting rod 6 synchronously drives the first scraper 7 and the second scraper 8 to rotate. The first scraper 7 continuously cleans the inner wall of the cylindrical section of the material bin 2, and the second scraper 8 cleans the inner wall of the conical guide hopper 3. The anti-stick coating on the scraper surface further reduces toner adhesion and prevents powder accumulation from affecting the filling accuracy.

[0029] A fixed clamping plate 9 is vertically installed on the upper surface of the U-shaped support base 1. An electric push rod 10 is installed on one side of the vertical section of the U-shaped support base 1. The transmission end of the electric push rod 10 passes through the U-shaped support base 1 and is fixedly connected to a push rod 11. A movable clamping plate 12 is fixedly connected to the end of the push rod 11 away from the electric push rod 10. Rubber pads 13 are embedded on the opposite surfaces of the movable clamping plate 12 and the fixed clamping plate 9. A fixed bracket 14 spans the top of the inner side of the U-shaped support base 1. An adjusting motor 15 is installed on one side inside the fixed bracket 14. An adjusting screw 16 is fixedly connected to the transmission end of the bottom of the adjusting motor 15. The end of the adjusting screw 16 away from the adjusting motor 15 is connected to the fixed bracket 14 through a bearing. An adjusting screw block 17 is threadedly connected to the outer surface of the adjusting screw 16. The adjusting screw block 17 slides with the fixed bracket 14. A lifting cylinder 18 is installed at the bottom of the adjusting screw block 17. A support frame 19 is fixedly connected to the transmission end of the bottom of the lifting cylinder 18. The material bin 2 is disposed through the middle of the support frame 19.

[0030] When refilling the toner cartridge, first place the cartridge on the U-shaped support base 1, positioning it between the fixed clamping plate 9 and the movable clamping plate 12. Activate the electric push rod 10; its transmission end pushes the push rod 11, causing the movable clamping plate 12 to move towards the fixed clamping plate 9. The cartridge is then flexibly clamped and fixed by the rubber pads 13 on opposite sides. Next, activate the adjusting motor 15 to drive the adjusting screw 16 to rotate, causing the adjusting screw block 17 to slide horizontally along the guide rail of the fixed bracket 14. Simultaneously, the piston rod of the lifting cylinder 18 extends and retracts, working together to adjust the horizontal and vertical positions of the support frame 19 and the material chamber 2. This ensures that the outlet of the conical guide hopper 3 at the bottom of the material chamber 2 is precisely aligned with the toner cartridge filling port. After filling, the lifting cylinder 18 and the adjusting motor 15 reverse their movements, resetting the material chamber 2. The electric push rod 10 retracts, moving the movable clamping plate 12 away from the fixed clamping plate 9, allowing the filled cartridge to be removed. The entire process achieves automated and coordinated operation of cartridge positioning, filling adjustment, and inner wall cleaning, making it highly efficient and convenient.

[0031] Working principle: When refilling the toner cartridge, first place the toner cartridge on the U-shaped support base 1, positioning it between the fixed clamping plate 9 and the movable clamping plate 12. Activate the electric push rod 10; the transmission end of the electric push rod 10 pushes the push rod 11, causing the movable clamping plate 12 to move towards the fixed clamping plate 9. The rubber pads 13 on opposite sides flexibly clamp and fix the toner cartridge. Next, activate the adjusting motor 15 to drive the adjusting screw 16 to rotate. The adjusting screw block 17 slides horizontally along the guide rail of the fixed bracket 14. Simultaneously, the piston rod of the lifting cylinder 18 extends and retracts. These actions work together to adjust the horizontal and vertical positions of the support frame 19 and the material bin 2, ensuring that the outlet of the conical guide hopper 3 at the bottom of the material bin 2 is precisely aligned with the toner cartridge filling port. Subsequently, the drive motor 4... The machine begins operation by rotating the screw conveyor shaft 5, which pushes the toner in the material bin 2 through the conical guide hopper 3 into the drum. During the rotation of the screw conveyor shaft 5, the connecting rod 6 simultaneously drives the first scraper 7 and the second scraper 8 to rotate. The first scraper 7 continuously cleans the inner wall of the cylindrical section of the material bin 2, while the second scraper 8 cleans the inner wall of the conical guide hopper 3. The anti-stick coating on the scraper surface further reduces toner adhesion and prevents powder accumulation from affecting the filling accuracy. After filling is completed, the lifting cylinder 18 and the adjusting motor 15 move in opposite directions to reset the material bin 2. The electric push rod 10 retracts, moving the movable clamp 12 away from the fixed clamp 9, allowing the filled drum to be removed. The entire process achieves automated and coordinated operation of drum positioning, filling adjustment, and inner wall cleaning, which is efficient and convenient.
