Description

Technical Field

[0001] The utility model relates to the technical field of toner cartridges, and specifically relates to a toner cartridge convenient for powder filling. Background Technique

[0002] With the continuous development of technology, printers have become one of the essential devices for people's office work. The toner cartridge, also known as the photosensitive drum, is one of the core components of the printer. The toner in the toner cartridge is the key to imaging during the printing process, so it is necessary to add toner to the toner cartridge regularly. The existing toner cartridge powder filling hole is designed to be small, making powder filling very inconvenient. Although a toner cartridge convenient for powder filling proposed in patent CN201922192006.4 can improve the powder filling efficiency to a certain extent, during use, it still requires manual continuous shaking to add toner, and its practicability needs to be improved.

[0003] To solve the above problems, an existing patent (publication number: CN218848573U) for a toner cartridge convenient for powder filling, through the design of a first motor, a second motor and a displacement sensor, can keep the toner amount in the toner cartridge always at the optimal set amount, avoid toner leakage caused by excessive toner, and at the same time, the above design will not cause toner to overflow, avoiding environmental pollution, and having good economy and environmental protection.

[0004] However, when adding toner to the toner cartridge in the above-mentioned published document, the toner cartridge is directly replaced, so this toner cartridge needs to be used with multiple toner cartridges, which increases the manufacturing cost to a certain extent, and at the same time, the agglomerated toner will also affect the toner addition.

[0005] Therefore, those skilled in the art provide a toner cartridge convenient for powder filling to solve the problems raised in the above background technique. Content of the Utility Model

By setting an activity mechanism, the activity mechanism mainly includes four movable plates that can move up and down. When moving the movable plates, the external diameter size of the pouring port can be adjusted, which is convenient for the staff to fill the powder. And by setting magnets to fix the movable plates, the fixation of the pouring port is realized. Secondly, by setting cutting blades, the toner falling from the pouring port can be crushed and cut in real time, which can effectively prevent the toner from agglomerating, ensure a good printing effect, and at the same time avoid the influence of the blocked agglomerated toner on the powder filling work, so as to solve the problems raised in the above background technique.

[0021] Please refer to Figures 1 to 4 , in an embodiment of the present utility model, a toner cartridge facilitating powder filling includes a toner cartridge main body 1 which can be filled with toner and is used for being installed at a designated position of a printer. A pouring opening 2 is provided at the upper end of the toner cartridge main body 1, and toner can be added into the toner cartridge main body 1 through the pouring opening 2. An inclined groove 4 is formed on the pouring opening 2, and a movable plate 3 is connected to the inclined groove 4 through a triangular block 5. The movable plate 3 can move along the inclined groove 4 through the triangular block 5. There are four movable plates 3. When the four movable plates 3 move upward, the distance between every two of them will gradually increase, thereby increasing the diameter of the pouring opening 2 to facilitate powder filling. And the connection cloth 9 is connected between every two movable plates 3 to prevent toner from leaking out.

[0022] A first magnet 6 is fixedly connected to the hypotenuse of the triangular block 5, and a second magnet 7 and a third magnet 8 are arranged on the inclined groove 4. Through the first magnet 6 and the second magnet 7, the movable plate 3 can be fixed at the lowest position. Through the first magnet 6 and the third magnet 8, the movable plate 3 can be fixed at the highest position.

[0023] An infrared sensor head 10 is arranged at the pouring opening 2. When toner passes through the pouring opening 2, the infrared sensor head 10 can perform real-time monitoring. An outer frame 11 is arranged inside the toner cartridge main body 1, and a driving motor 12 is arranged inside the outer frame 11. When the infrared sensor head 10 senses the falling of toner, it will make the driving motor 12 work through the control system, thereby driving the connecting rod 13 and the connecting block 14 to rotate, and finally making the cutting blade 15 rotate to realize the cutting and pulverization of the toner, so as to avoid the influence of agglomerated toner on the printing work.

[0024] The working principle of the present utility model is as follows: When it is necessary to add toner into the toner cartridge main body 1, at this time, the movable plate 3 is pulled upward along the inclined groove 4. The movable plate 3 will move upward along the inclined groove 4 through the triangular block 5. When the four movable plates 3 move to the uppermost position, the movable plate 3 will be fixed by the first magnet 6 and the third magnet 8. At this time, the distance between the movable plates 3 increases, thereby increasing the diameter of the pouring port 2 to facilitate the pouring of toner. At the same time, the movable plates 3 are connected by a connecting cloth 9, and the toner will not leak out between the two movable plates 3. When the toner drops through the pouring port 2, the infrared sensor head 10 monitors it. After monitoring, the control system makes the drive motor 12 work, thereby driving the connecting rod 13 and the connecting block 14 to rotate, and finally making the cutting blade 15 rotate to realize the cutting of the dropped toner, preventing the toner from caking and affecting the printing work, ensuring a good printing effect, and at the same time avoiding the caked toner from blocking the pouring port and affecting the toner filling efficiency.

[0025] The above is only the preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, making equivalent substitutions or changes should be covered within the protection scope of the present utility model.
