Description

Technical Field

[0001] The utility model relates to the technical field of printer toner cartridges, in particular to a toner stirring mechanism for a printer toner cartridge. Background Art

[0002] Most of the existing toner cartridges use a stirring device to stir the toner when in use, so that the stirred toner contacts the static electricity roller. Then, driven by the driving mechanism of the printer, the static electricity roller, the adsorption roller and the selenium drum rotate, so that toner particles corresponding to the pattern are presented on the surface of the selenium drum. However, when in use, most stirring devices mostly use spring pieces arranged in the powder cavity to stir the toner. However, the elasticity of the existing spring pieces may decrease after long-term use, thereby reducing the stirring effect of the device, which may cause the toner not to be evenly distributed on the static electricity roller, reducing the printing quality of the device.

[0003] Mostly, a powder adding port is arranged on the toner cartridge 1 to add toner. Figure 1 Among them, most of the existing powder adding ports are blocked by a plastic plug 2. The sealing effect depends on the powder adding port squeezing the plastic plug. If it is squeezed too tightly, it is not convenient to remove the plastic plug 2. If it is squeezed loosely, the sealing effect is poor. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a toner stirring mechanism for a printer toner cartridge to solve the problems put forward in the above background art.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A toner stirring mechanism for a printer toner cartridge, including a cartridge body. A rotating tube is installed inside the cartridge body. A plurality of support arms are fixedly connected to the surface of the rotating tube, and the support arms are arc-shaped;

[0006] Spring plates. A plurality of spring plates are arranged and installed on the surface of the rotating tube. The spring plates are arc-shaped, and the radian of the spring plates corresponds to that of the support arms. The spring plates are connected to the inner arc surface of the support arms, and the support arms are used to assist in supporting the spring plates to keep the elasticity of the spring plates from decaying easily;

[0007] Sealing caps. The sealing caps are installed on the surface of the cartridge body. The sealing caps are provided with inclined surface sealing rings, and the inclined surface sealing rings abut against the inside of the cartridge body, and the sealing effect is better.

[0008] Further, a driving shaft is installed on the surface of the cartridge body, and the driving shaft extends into the cartridge body. The driving shaft is in transmission connection with the rotating tube. Synchronization strips are arranged on the surface of the driving shaft, and synchronization grooves corresponding to the sizes of the synchronization strips are arranged on the inner wall of the rotating tube. By driving the spring plates to rotate through the driving shaft, the toner can be stirred.

[0009] Furthermore, a powder adding port is provided on the cartridge body. An extension tube corresponding to the powder adding port is provided inside the cartridge body. The inclined surface sealing ring abuts against the extension tube, which can prevent the sealing cap from separating from the cartridge body. A pull ring is fixedly connected inside the sealing cap, which is convenient for removing the sealing cap.

[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0011] (1) The support arm on the rotating tube supports the spring plate, preventing the attenuation of the elasticity of the spring plate. When the spring plate rotates, the support arm can prevent the spring plate from being overly deformed, thereby improving the elasticity of the spring plate, ensuring that the toner can be smoothly adsorbed on the surface of the electrostatic roller, improving the printing quality of the device. The spring plates are independently designed and do not interfere with each other, avoiding the problem of elastic attenuation of all the spring plates.

[0012] (2) The sealing cap is inserted into the cartridge body. The inclined surface sealing ring can be blocked by the extension tube, which can improve the sealing effect, prevent toner leakage and moisture absorption. Using the pull ring is convenient for removing the sealing cap and facilitating the replenishment of toner in the cartridge body. Description of the Drawings

Embodiment

[0020] Please refer to Figure 2-5 , the present utility model provides a technical solution: a toner stirring mechanism for a printer toner cartridge, including a cartridge body 3, a rotating tube 5 is installed inside the cartridge body 3, and a plurality of support arms 6 are fixedly connected to the surface of the rotating tube 5, and the support arms 6 are arranged in an arc shape. The support arms 6 are elastic and can elastically support the spring plate 7;

[0021] Spring plate 7, a plurality of spring plates 7 are provided and installed on the surface of the rotating tube 5. The spring plates 7 are arranged in an arc shape, and the arc of the spring plates 7 corresponds to that of the support arms 6. The spring plates 7 are connected to the inner arc surface of the support arms 6 to ensure that the spring plates 7 are in contact with the support arms 6. Even after long-term use, the spring plates 7 are not prone to deformation problems, and the stirring force for the toner is sufficient;

[0022] Sealing cap 4, which is installed on the surface of the cartridge body 3. The sealing cap 4 is provided with an inclined surface sealing ring 15, and the inclined surface sealing ring 15 abuts against the inside of the cartridge body 3. The inclined surface sealing ring 15 and the sealing cap 4 cooperate to clamp the cartridge body 3, realizing a stable and sealed connection between the cartridge body 3 and the sealing cap 4.

[0023] In this embodiment, as Figure 3 shown, a drive shaft 9 is installed on the surface of the cartridge body 3, and the drive shaft 9 extends into the cartridge body 3. The drive shaft 9 is in transmission connection with the rotating tube 5. A synchronous strip 10 is provided on the surface of the drive shaft 9, and a synchronous groove 11 corresponding to the size of the synchronous strip 10 is provided on the inner wall of the rotating tube 5. The drive shaft 9 drives the rotating tube 5 to rotate through the synchronous strip 10 and the synchronous groove 11, and the rotating tube 5 drives the spring plate 7 to rotate to stir the toner.

[0024] In this embodiment, as Figure 4 shown, the cartridge body 3 is provided with a powder adding port, and an extension tube 8 corresponding to the powder adding port is provided inside the cartridge body 3. The inclined surface sealing ring 15 abuts against the extension tube 8. The sealing cap 4 and the inclined surface sealing ring 15 are integrally formed and soft, which can not only improve the sealing effect but also facilitate the removal of the sealing cap 4.

[0025] In this embodiment, as Figure 5 shown, a fixed head 12 is provided on the surface of the support arm 6, and a round hole 13 is provided on the surface of the spring plate 7. The fixed head 12 passes through the round hole 13 and is stuck on the surface of the spring plate 7, realizing the reinforced connection between the support arm 6 and the spring plate 7.

The motor of the printer drives the drive shaft 9 to rotate, and the drive shaft 9 drives the rotating tube 5 to rotate. The support arm 6 and the spring plate 7 rotate synchronously with the rotating tube 5. The degree of compression of the spring plate 7 due to being squeezed by the inner wall of the cartridge body 3 is large. When the spring plate 7 is compressed, the support arm 6 provides auxiliary support for the spring plate 7, which can prevent the spring plate 7 from being excessively bent and losing its elasticity, improve and extend the elasticity of the spring plate 7, ensure that the toner can be smoothly adsorbed on the surface of the electrostatic roller, and improve the printing quality of the device;
