Technical Field
[0001] This utility model relates to the field of toner cartridge technology, specifically a toner cartridge structure with an integrally formed gear. Background Technology
[0002] The toner cartridge is a component in a printer used to store toner. Its main function is to provide toner for the printing process, ensuring print quality and efficiency. The toner in the cartridge is evenly delivered to the photosensitive drum through a toner delivery system. During the printing process, a laser beam forms a latent image on the photosensitive drum according to the printed content. The toner is adsorbed onto the latent image to form visible printed text or images. Existing toner cartridges have some shortcomings in use. In order to meet market needs, a toner cartridge structure with an integrated gear is required.
[0003] Existing powder silo structures are costly and inconvenient to use. Furthermore, they typically lack integrated gear functionality, reducing transmission efficiency and stability, increasing the number of parts, raising production costs, and lowering the reliability of the silo itself. In addition, the sealing and leak-proof performance of existing powder silo structures needs improvement. The presence of seals can interfere with the normal movement of toner, preventing leaks and contamination, thus reducing the silo's overall sealing performance. Utility Model Content
[0004] The purpose of this utility model is to provide a powder hopper structure with an integrated gear, so as to solve the problems mentioned in the background art that the powder hopper structure usually does not have the function of integrated gear and the sealing and anti-leakage effect needs to be further improved.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a powder hopper structure integrally formed with a gear, comprising a powder hopper body, a side cover mounted on the surface of the powder hopper body by screws, an end cover mounted on the surface of the powder hopper body away from the side cover by screws, a developing roller disposed inside the powder hopper body, a gear cover disposed on the surface of the powder hopper body, one end of the gear cover extending into the interior of the end cover, a stirring frame disposed inside the powder hopper body, a powder guiding roller disposed inside the powder hopper body, a gear body fitted onto the surfaces of both the stirring frame and the powder guiding roller, a drive rod disposed on the surface of the gear cover, a cost reduction mechanism disposed inside the powder hopper body and on the surface of the gear cover, and a sealing and anti-leakage mechanism disposed inside the powder hopper body and on the surface of the developing roller.
[0006] Preferably, the developing roller and the inner wall of the powder hopper body are rotatably engaged, the powder hopper body is provided with a scraper inside, and the surface of the scraper is provided with an installation groove. The installation groove is engaged with the inner wall of the powder hopper body. The stirring frame and the inner wall of the powder hopper body are rotatably engaged, and the powder guiding roller and the inner wall of the powder hopper body are rotatably engaged.
[0007] Preferably, the sealing and leak-proof powder mechanism consists of a sealing cover, a sealing cylinder, a sealing element, and a connecting rod. The surface of the powder hopper body is provided with a sealing cover, which is engaged with the surface of the powder hopper body. A sealing cylinder is installed on the inner wall of the sealing cover.
[0008] Preferably, a connecting rod is installed on one side of the developing roller, one end of the connecting rod extends into the interior of the sealing cylinder and rotates with the inner wall of the sealing cylinder, and a sealing element is installed on the surface of the sealing cylinder.
[0009] Preferably, the cost reduction mechanism consists of a gear assembly, a drive gear, a through groove, and a rubber clip. The powder hopper body is provided with a drive gear inside, and the inner wall of the gear cover is provided with a through groove. One end of the drive gear extends into the inside of the through groove and rotates with the inner wall of the through groove.
[0010] Preferably, the inner wall of each drive gear is fitted with a rubber clip, the surface of which is in contact with the surface of the drive rod. A gear assembly is mounted on the surface of the drive gear, one end of which extends into the interior of the powder hopper body. The drive gear meshes with the gear body.
[0011] Compared with the prior art, the beneficial effects of this utility model are: the powder hopper structure with the gear integral molding not only improves the efficiency and stability of the transmission when the powder hopper structure is used, but also simplifies the number of parts, thereby reducing the production cost and improving the reliability of the powder hopper body when in use. Moreover, it can prevent the presence of the seal from affecting the normal movement of the toner when the powder hopper structure is used, so that the powder hopper structure can achieve the effect of sealing and preventing powder leakage and contamination when in use, thus improving the sealing performance of the powder hopper.
[0012] 1. By incorporating a cost-reducing mechanism, the user places the drive gear and gear assembly on the surface of the gear cover, allowing one end of the drive gear to insert into the through slot. The rubber clips on the inner wall of the gear cover move to contact the surface of the drive rod, improving the stability of the drive rod when it is inserted into the drive gear surface. This allows the drive rod to drive the drive gear and gear assembly to rotate stably. Since the drive gear and gear assembly are an integrated structure, the efficiency and stability of the drive gear and gear assembly during transmission are improved, saving costs and ensuring the toner cartridge's powder dispensing efficiency.

[0013] 2. By incorporating a sealing and leak-proof powder mechanism, before assembling the side cover, the user first assembles the sealing cover onto the surface of the powder hopper body. The connecting rod on the surface of the stirring frame automatically moves into the interior of the sealing cylinder. Under the action of the sealing element, the stability of the sealing cover assembly is improved. The combined action of the connecting rod and the sealing cylinder enhances the sealing effect on the powder hopper body, preventing toner leakage during transportation and use. This achieves the function of sealing and preventing powder leakage in the powder hopper structure, thus preventing the presence of the seal from affecting the normal movement of the toner. This ensures that the powder hopper structure achieves a sealing and leak-proof effect, preventing powder leakage and contamination, and improving the sealing performance of the powder hopper.

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.
[0022] The structure of the powder hopper structure integrally formed by gears provided by this utility model is as follows: Figure 1 and Figure 2 As shown, the device includes a powder hopper body 1. A side cover 101 is screwed onto the surface of the powder hopper body 1. An end cover 102 is screwed onto the surface of the powder hopper body 1 away from the side cover 101. A developing roller 103 is disposed inside the powder hopper body 1. The developing roller 103 rotates with the inner wall of the powder hopper body 1. A scraper 104 is disposed inside the powder hopper body 1. Each scraper 104 has a mounting groove 105 on its surface. The mounting groove 105 engages with the inner wall of the powder hopper body 1. A gear cover 106 is disposed on the surface of the powder hopper body 1. One end of the gear cover 106 extends into the interior of the end cover 102. A stirring frame 107 is disposed inside the powder hopper body 1. The stirring frame 107 rotates with the inner wall of the powder hopper body 1. A powder guide roller 108 is disposed inside the powder hopper body 1. The powder guide roller 108 rotates with the inner wall of the powder hopper body 1. Gear bodies are fitted onto the surfaces of both the stirring frame 107 and the powder guide roller 108. A drive rod 109 is disposed on the surface of the gear cover 106.
[0023] Furthermore, such as Figure 4 and Figure 5As shown, a cost reduction mechanism 3 is provided inside the powder hopper body 1 and on the surface of the gear cover 106. The cost reduction mechanism 3 consists of a gear assembly 31, a drive gear 32, a through groove 33, and a rubber clip 34. The drive gear 32 is provided inside the powder hopper body 1. A through groove 33 is provided on the inner wall of the gear cover 106. One end of the drive gear 32 extends into the inside of the through groove 33 and rotates with the inner wall of the through groove 33. Rubber clips 34 are installed on the inner wall of the drive gear 32. The surface of the rubber clips 34 contacts the surface of the drive rod 109. A gear assembly 31 is installed on the surface of the drive gear 32. One end of the gear assembly 31 extends into the inside of the powder hopper body 1. The drive gear 32 meshes with the gear body.
[0024] During implementation, the user places the drive gear 32 and gear assembly 31 on the surface of the gear cover 106, so that one end of the drive gear 32 is inserted into the inside of the through slot 33. The rubber clip 34 on the inner wall of the gear cover 106 moves to contact the surface of the drive rod 109, which improves the stability of the drive rod 109 when it is inserted into the surface of the drive gear 32. This allows the drive rod 109 to drive the drive gear 32 and gear assembly 31 to rotate stably. Since the drive gear 32 and gear assembly 31 are an integrated structure, the efficiency and stability of the drive gear 32 and gear assembly 31 during transmission can be improved, saving costs and ensuring the toner cartridge's toner dispensing efficiency, thus realizing the integrated function of the toner cartridge structure gear.
[0025] Furthermore, such as Figure 4 and Figure 6 As shown, a sealing and anti-leakage mechanism 2 is provided inside the powder hopper body 1 and on the surface of the developing roller 103. The sealing and anti-leakage mechanism 2 consists of a sealing cover 21, a sealing cylinder 22, a sealing element 23, and a connecting rod 24. The surface of the powder hopper body 1 is provided with a sealing cover 21, which is engaged with the surface of the powder hopper body 1. A sealing cylinder 22 is installed on the inner wall of the sealing cover 21. A connecting rod 24 is installed on one side of the surface of the developing roller 103. One end of the connecting rod 24 extends into the interior of the sealing cylinder 22 and rotates with the inner wall of the sealing cylinder 22. A sealing element 23 is installed on the surface of the sealing cylinder 22.
[0026] During implementation, the sealing cover 21 is assembled onto the surface of the powder hopper body 1. The connecting rod 24 on the surface of the stirring frame 107 automatically moves into the interior of the sealing cylinder 22. Under the action of the sealing element 23, the stability of the sealing cover 21 during assembly is improved. Under the combined action of the connecting rod 24 and the sealing cylinder 22, the sealing effect on the powder hopper body 1 can be improved, preventing the powder hopper body 1 from leaking out during transportation and use, so as to achieve the function of sealing and preventing powder leakage in the powder hopper structure.
[0027] Working principle: In use, first place the toner cartridge body 1 in the designated position. The user then assembles the side cover 101 and end cover 102 onto the surface of the toner cartridge body 1 using screws. Toner is stored inside the toner cartridge body 1. The toner guide roller 108 is responsible for conveying the toner from inside the toner cartridge body 1 to the drum unit. The scraper 104 is installed inside the toner cartridge body 1 via the mounting groove 105. The scraper 104 controls the toner thickness and the amount of toner delivered each time, ensuring stable printing quality. The stirring rack 107 ensures the toner... The toner is evenly distributed within the toner cartridge body 1 to prevent sedimentation. Under the action of the developing roller 103, the toner is drawn out from the toner cartridge body 1 and rubbed to make it charged. Then, the toner is transferred to the photosensitive drum in the drum unit (not shown in the diagram). When the external drive assembly (not shown in the diagram) drives the drive rod 109 to rotate, the drive rod 109 drives the drive gear 32 and gear assembly 31 to rotate on the gear cover 106 and the inner wall of the toner cartridge body 1, thereby driving the photosensitive drum (not shown in the diagram) to rotate inside the toner cartridge body 1, and printing can then begin.
[0028] Subsequently, the user places the drive gear 32 and gear assembly 31 on the surface of the gear cover 106, so that one end of the drive gear 32 is inserted into the inside of the through slot 33. The rubber clip 34 on the inner wall of the gear cover 106 moves to contact the surface of the drive rod 109, which improves the stability of the drive rod 109 when it is inserted into the surface of the drive gear 32, so that the drive rod 109 can drive the drive gear 32 and gear assembly 31 to rotate stably. Since the drive gear 32 and gear assembly 31 are an integral structure, the efficiency and stability of the drive gear 32 and gear assembly 31 during transmission can be improved, saving costs and ensuring the toner cartridge's powder dispensing efficiency, so as to realize the function of the integrated gear of the powder hopper structure. This makes the powder hopper structure more efficient and stable during transmission, simplifies the number of parts, reduces production costs, and improves the reliability of the powder hopper body 1 during use.
[0029] The traditional method of sealing the powder hopper body 1 before use involves setting a seal at the powder outlet of the powder hopper body 1 to prevent the toner inside the powder hopper body 1 from leaking out during transportation. This method is not convenient to use, and the seal may be difficult to remove. Specifically, if the seal is not removed in time and correctly, it will cause the gears to run poorly, affecting the powder dispensing volume. In this case, before assembling the side cover 101, the user should first assemble the sealing cover 21 onto the surface of the powder hopper body 1. The connecting rod 24 on the surface of the stirring frame 107 will automatically move to the sealing cylinder. Inside 22, the stability of the sealing cover 21 during assembly is improved by the sealing element 23. The joint action of the connecting rod 24 and the sealing cylinder 22 can improve the sealing effect on the powder hopper body 1, preventing the powder hopper body 1 from leaking out during transportation and use. This achieves the function of sealing and preventing powder leakage in the powder hopper structure, thus preventing the presence of the seal from affecting the normal movement of the powder during use. This ensures that the powder hopper structure can achieve the effect of sealing and preventing powder leakage and contamination during use, improving the sealing performance of the powder hopper and finally completing the use of the powder hopper structure.
