Specific embodiments

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] As Figures 1 to 6 shown, the present utility model provides a toner cartridge structure convenient for powder replenishment, including a toner cartridge 1. A powder outlet 2 is provided at the bottom of the toner cartridge 1. A sponge roller 3, a developing roller 4, and a charging roller 10 are rotatably connected inside the toner cartridge 1. A first telescopic rod 5 is clamped inside the toner cartridge 1. A first spring 6 is sleeved outside the first telescopic rod 5. A limiting plate 7 is fixedly installed on the side of the first spring 6 close to the center point of the toner cartridge 1. A connecting shaft 8 is fixedly installed on the side of the limiting plate 7 away from the first spring 6. An OPC roller 9 is rotatably connected outside the connecting shaft 8.

[0024] The inside of the toner cartridge 1 is hollow. When the inside of the toner cartridge 1 is filled with toner powder, it will accumulate inside the powder outlet 2. As the sponge roller 3 rotates, the toner powder will be carried to the outside of the developing roller 4 for transportation.

[0025] Among them, a charging roller 10 is rotatably connected inside the toner cartridge 1. The charging roller 10 is located above the OPC roller 9, and the distance between its surface and the surface of the OPC roller 9 is relatively small.

[0026] The surface of the charging roller 10 is covered with a large number of charged particles. When the charging roller 10 rotates, the charged particles will be distributed on the surface of the OPC roller 9, thereby adsorbing the toner powder on the surface of the developing roller 4 to form the required pattern.

[0027] Among them, a powder injection port 11 is provided at the top of the toner cartridge 1, a sliding groove 12 is provided inside the toner cartridge 1, a slider 13 is slidably connected inside the sliding groove 12, and a sealing plate 14 is fixedly installed on one side of the slider 13 away from the sliding groove 12.

[0028] The sealing plate 14 covers the powder injection port 11, so that when toner is injected into the toner cartridge 1, it can prevent the toner inside from leaking out during transportation.

[0029] Among them, a fixing plate 15 is fixedly installed above the toner cartridge 1, a second telescopic rod 16 is fixedly installed on the right side of the fixing plate 15, a second spring 17 is sleeved outside the second telescopic rod 16, and a connecting plate 18 is fixedly installed on one side of the second spring 17 away from the fixing plate 15.

[0030] The connecting plate 18 is located above the sealing plate 14 and is fixedly connected to the sealing plate 14. The second spring 17 will always provide an elastic force to push the connecting plate 18 to the right, thereby driving the sealing plate 14 to always maintain a sealed state.

[0031] Among them, the sponge roller 3 is located behind the developing roller 4, the developing roller 4 is located behind the OPC roller 9, and the distances between the sponge roller 3 and the developing roller 4 and between the developing roller 4 and the OPC roller 9 are both small.

[0032] After the sponge roller 3 transfers the toner to the surface of the developing roller 4, it will clean the toner at the bottom of the developing roller 4 through rotation, ensuring that the toner in contact with the surface of the developing roller 4 is uniform and non-repetitive.

[0033] Among them, there are two first telescopic rods 5, two first springs 6 and two limiting plates 7. The two first telescopic rods 5, the two first springs 6 and the two limiting plates 7 are respectively located on the left and right sides of the center point of the toner cartridge 1.

[0034] The two first telescopic rods 5 are located on the left and right sides of the toner cartridge 1. The two first springs 6 provide an elastic force to keep the first telescopic rods 5 always inside the toner cartridge 1. When disassembly is required, the two first telescopic rods 5 are respectively pressed towards the two limiting plates 7, so as to achieve the effect of convenient disassembly.

[0035] Among them, there are two sliding grooves 12 and two sliders 13. The two sliding grooves 12 and the two sliders 13 are both located inside the toner cartridge 1.

[0036] The two sliders 13 slide inside the two sliding grooves 12 respectively, thereby driving the sealing plate 14 to slide, facilitating the opening and sealing of the sealing plate 14.

[0037] Among them, there are two fixing plates 15, two second telescopic rods 16 and two second springs 17. The two fixing plates 15 are both located above the toner cartridge 1, and the two second telescopic rods 16 and the two second springs 17 are both fixedly connected to the connecting plate 18.

[0038] Two springs II 17 provide greater elasticity, improving the sealing performance of the sealing plate 14 above the toner cartridge 1. At the same time, the connecting plate 18 is pushed towards the fixing plate 15, causing the telescopic rod II 16 to contract, thereby opening the sealing plate 14 to achieve the effect of facilitating powder injection.

[0039] The working principle and usage process of the present utility model are as follows:

[0040] First, the entire toner cartridge is installed inside the printer. When printing is required, the toner inside the toner cartridge 1 first flows through the powder outlet 2 onto the surface of the sponge roller 3. As the sponge roller 3 rotates, it is transported to the surface of the developing roller 4. At the same time, the charging roller 10 rotates to transfer the charged particles on its surface to the surface of the OPC roller 9. At the same time, the OPC roller 9 rotates, causing the toner to combine with the charged particles and then be rolled onto the surface of the paper to complete the overall printing.

[0041] Among them, when the surface of the OPC roller 9 is damaged after long-term printing, the telescopic rod I 5 is pressed towards the limiting plate 7, causing the telescopic rod I 5 to contract, and the spring I 6 will also be squeezed towards the limiting plate 7. At this time, the telescopic rod I 5 will fall off from the inside of the toner cartridge 1, so that the entire OPC roller 9 can be disassembled, thus achieving the effect of being easy to disassemble and facilitating maintenance.

[0042] Finally, when the toner inside the toner cartridge 1 is used up, the connecting plate 18 drives the sealing plate 14 to be pushed towards the fixing plate 15. At this time, the powder injection port 11 will be opened. After injecting new toner into the powder injection port 11, the connecting plate 18 is released, and the spring II 17 will provide elastic force to push the connecting plate 18 to the right side of the powder injection port 11 so that the sealing plate 14 seals the powder injection port 11, achieving the effects of sealing and facilitating toner addition.

[0043] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variation thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or elements inherent to such process, method, article or device.

[0044] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
