Description

Technical Field

[0001] This utility model relates to the field of toner cartridge opening technology, specifically to a toner cartridge opening device. Background Technology

[0002] The toner cartridge is a crucial component in laser printers, copiers, and laser multifunction printers. It stores toner and is the dedicated toner storage section in toner-separate printers. It does not contain the photosensitive element and works in conjunction with the drum unit to complete the printing task. The toner cartridge typically contains an agitator to ensure smooth toner delivery and prevent sedimentation. During printing, toner is transported from the cartridge to the developing roller, and then to the photosensitive drum to form the image.

[0003] Toner cartridges have limited capacity, and toner is gradually consumed during printing. With the opening design, users can directly inject new toner into the cartridge, avoiding waste of undamaged components such as the drum core and scraper. The opening of the existing toner cartridge is manually drilled, but manual drilling may damage the original sealing of the cartridge or the toner flow design, resulting in uneven toner supply during printing, causing problems such as blurry text, color deviation, or increased background grayness.

[0004] To address this, a toner cartridge opening device is proposed. Utility Model Content

[0005] The purpose of this invention is to solve the problem of blurred text when manually punching holes, and to provide a hole-opening device for the toner cartridge.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0007] A toner cartridge opening device includes a cartridge body, with mirror-image opening mechanisms on the left and right sides of the cartridge body, and filling ports on both the left and right sides of the cartridge body. A roller cartridge body is provided on the rear side of the cartridge body, with a rectangular groove on the top of the roller cartridge body, and a roller inside the rectangular groove. An opening assembly for driving the opening mechanism to move is provided at the bottom of the cartridge body, and a clamping assembly for positioning the opening assembly at the bottom of the cartridge body is provided at the bottom of the cartridge body. A fixing assembly for easy disassembly is provided between the cartridge body and the roller cartridge body.

[0008] Furthermore, the opening assembly includes a fixed frame disposed at the bottom of the chamber body, a rectangular hole is provided at the top of the fixed frame, a stepper motor is disposed on the right side of the fixed frame, a rotating shaft is disposed at the output end of the stepper motor, and threaded grooves with opposite directions are disposed on the left and right sides of the output end of the rotating shaft, a fixed rod is disposed inside the fixed frame, and two movable plates are disposed between the fixed rod and the rotating shaft.

[0009] Furthermore, the opening mechanism is respectively set on the side of the movable plates that are close to each other, one end of the bottom of each movable plate is movably connected to the wall of the fixed rod, and the other side of the bottom of each movable plate is threaded to the wall of the rotating shaft.

[0010] Furthermore, the clamping assembly includes movable blocks disposed on the left and right sides of the top of the opening assembly, a spring is disposed between the movable blocks, a limit block is disposed at the bottom of each movable block, a limit groove is provided on the side of the top of the opening assembly near the limit block, the limit blocks are movably connected to the inside of the limit groove, and a clamping plate is disposed on the top of each movable block.

[0011] Furthermore, the roller chamber includes protrusions at the left and right ends of the rear side of the chamber, and rectangular grooves are provided at the left and right ends of the front side of the roller chamber.

[0025] like Figures 1 to 5As shown, a toner cartridge opening device includes a cartridge body 1. Mirror-aligned opening mechanisms 2 are provided on the left and right sides of the cartridge body 1. The opening mechanism 2 is prior art and will not be elaborated further. Injection ports 201 are provided on both the left and right sides of the cartridge body 1. A roller cartridge body 5 is provided on the rear side of the cartridge body 1. A rectangular groove 501 is provided on the top of the roller cartridge body 5. A roller 502 is installed inside the rectangular groove 501. An opening assembly 3 for driving the opening mechanism 2 is provided at the bottom of the cartridge body 1. Figures 2-3 As shown, specifically, the opening assembly 3 includes a fixed frame 301 set at the bottom of the chamber 1. A rectangular hole 302 is opened at the top of the fixed frame 301. A stepper motor 303 is set on the right side of the fixed frame 301. A rotating shaft 304 is set at the output end of the stepper motor 303. Threaded grooves with opposite rotation directions are set on the left and right sides of the output end of the rotating shaft 304. A fixed rod 305 is set inside the fixed frame 301. Two movable plates 306 are set between the fixed rod 305 and the rotating shaft 304. The opening mechanism 2 is set on the side of the movable plates 306 that are close to each other. One end of the bottom of each movable plate 306 is movably connected to the wall of the fixed rod 305. The other end of the bottom of each movable plate 306 is threadedly connected to the wall of the rotating shaft 304.

[0026] More specifically, when the external controller is activated, the stepper motor 303 is activated. During the rotation process, the stepper motor 303 drives the rotating shaft 304 to rotate in the forward direction. The rotating shaft 304 then drives the movable plate 306 to move through the threaded groove at its output end. The movable plate 306 is limited in its movement trajectory by the fixed rod 305 on one side of its bottom, causing the movable plate 306 to drive the opening mechanism 2 to move in a direction closer to each other. This allows the opening mechanism 2 to make holes on the left and right sides of the cartridge 1. Through the self-drilling of the opening mechanism 2, the service life of the toner cartridge is extended, printer malfunctions caused by toner cartridge problems are reduced, and maintenance and replacement costs are lowered.

[0027] The bottom of the compartment 1 is provided with a clamping component 4 for positioning the opening component 3 at the bottom of the compartment 1, such as... Figures 2-3 As shown, specifically, the clamping assembly 4 includes movable blocks 401 disposed on the left and right sides of the top of the opening assembly 3, a spring 402 disposed between the movable blocks 401, a limit block 403 disposed at the bottom of each movable block 401, a limit groove 404 disposed on the side of the top of the opening assembly 3 near the limit block 403, the limit block 403 being movably connected to the inside of the limit groove 404, and a clamping plate 405 disposed on the top of each movable block 401.

[0028] More specifically, the worker pulls the movable block 401 to move it away from each other. The spring 402 deforms after being pulled, and begins to stretch and lengthen. Then, the clamping plates 405 are placed on the left and right sides of the chamber 1 respectively. The pull on the movable block 401 is released, thereby clamping the movable block 401 at the bottom of the chamber 1. This causes the opening assembly 3 and the opening mechanism 2 to be located at the bottom of the chamber 1. After the opening mechanism 2 has completed the opening, the worker continues to pull the movable block 401 to remove it from the bottom of the chamber 1. This causes the opening assembly 3 and the opening mechanism 2 to detach from the bottom of the chamber 1.

[0029] A easily removable fixing component 7 is provided between the chamber body 1 and the drum chamber body 5, such as... Figure 5 As shown, specifically, the roller chamber 5 includes protrusions 701 at the left and right ends of the rear side of the chamber 1, and rectangular grooves 702 are provided at the left and right ends of the front side of the roller chamber 5. A spring 703 is provided inside the rectangular groove 702, and a clamping ball 704 is provided at the output end of the spring 703.

[0030] More specifically, by pressing the protrusion 701 backward, the process of the protrusion 701 moving backward pushes the clamping ball 704 to move away from each other. The second spring 703 receives the pressure and begins to rebound and contract, which in turn drives the clamping ball 704 to retract. When the bottom of the protrusion 701 is in contact with the bottom of the inner side of the rectangular groove 702, the second spring 703 loses pressure and restores tension. The second spring 703 drives the clamping ball 704 to be locked on the left and right sides of the protrusion 701 through tension, so as to facilitate the installation and disassembly of the chamber 1 and the roller chamber 5.

[0031] Handles 6 are fixedly connected to both the left and right sides of the drum chamber 5.

[0032] The handle 6 allows staff to easily remove the drum chamber 5.

[0033] In summary: When stepper motor 303 starts, it drives shaft 304 to rotate in the forward direction. Shaft 304 then moves movable plate 306 through the threaded groove at its output end. Movable plate 306's movement trajectory is limited by fixed rod 305 on one side of its bottom, causing movable plate 306 to move the opening mechanism 2 towards each other. This allows the opening mechanism 2 to make holes on the left and right sides of the cartridge 1. Through the self-drilling function of the opening mechanism 2, the lifespan of the toner cartridge is extended, printer malfunctions caused by toner cartridge problems are reduced, and repair and replacement costs are lowered. In this process, the worker pulls the movable block 401 to move it away from each other. The spring 402 deforms after being pulled, and begins to stretch and lengthen. Then, the clamping plates 405 are placed on the left and right sides of the chamber 1 respectively. The pull on the movable block 401 is released, thereby clamping the movable block 401 at the bottom of the chamber 1. This causes the opening assembly 3 and the opening mechanism 2 to be located at the bottom of the chamber 1. After the opening mechanism 2 has completed the opening, the worker continues to pull the movable block 401 to remove it from the bottom of the chamber 1, thereby causing the opening assembly 3 and the opening mechanism 2 to detach from the bottom of the chamber 1.
