Description

Technical Field

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

[0002] Toner cartridges, also known as photosensitive drums, are typically composed of a base aluminum substrate coated with a photosensitive material. In laser printers, over 70% of the imaging components are concentrated in the toner cartridge, and print quality is largely determined by the toner cartridge.

[0003] During the use of traditional toner cartridges, waste powder needs to be discharged regularly. In the actual powder discharge operation, because waste powder is easy to be clogged in the powder outlet, the toner cartridge body is often slapped or knocked to use the vibration generated to assist in the discharge of waste powder. However, vibration can easily cause the installation of various parts of the toner cartridge to loosen, affecting the normal operation of the toner cartridge and increasing the subsequent maintenance burden. Therefore, there is an urgent need for a toner cartridge structure for printers to solve the above problems. Utility Model Content

[0004] In order to overcome the above-mentioned technical problems, the purpose of the present invention is to provide a toner cartridge structure for a printer, so as to solve the problem raised in the above-mentioned background technology that in the actual powder discharge operation, because waste powder is easily blocked at the powder outlet hole, the toner cartridge body is often slapped or knocked, and the vibration generated is used to assist in the discharge of waste powder. However, the vibration can also easily cause the installation of various parts of the toner cartridge to loosen, resulting in the normal operation of the toner cartridge being affected, and increasing the subsequent maintenance burden.

[0005] The utility model provides the following technical solution: a toner cartridge structure for a printer, comprising a drum body mechanism, the drum body mechanism comprising a photosensitive drum, and a blocking block inserted into a powder outlet hole of a waste toner storage portion of the photosensitive drum, the waste toner storage portion of the photosensitive drum having two symmetrical powder outlet holes, and the number of blocking blocks adapted to the two symmetrical powder outlet holes;

[0006] A cleaning mechanism comprising a plastic spring located inside the photosensitive drum and connected at both ends to two blocking blocks. When the two blocking blocks are respectively inserted into the two powder outlet holes of the photosensitive drum, the plastic spring is in a linear, non-deformed state.

[0007] A pulling mechanism is provided on the two blocking blocks.

[0008] To implement the above technical solution, two sealing blocks are pulled to drive the plastic spring to move and deform in the waste toner bin of the photosensitive drum, thereby driving the waste toner to be discharged toward the powder outlet hole of the photosensitive drum. Compared with the existing technology, this device improves the fluidity of the waste toner through the movement of the plastic spring, making it less likely to get clogged. At the same time, there is no need to beat the photosensitive drum to avoid loosening of the installation position of some of its parts.

[0009] Furthermore, a blocking bar is connected to the waste toner bin of the photosensitive drum on the back of the plastic spring, and cavities for waste toner to pass through are reserved at the upper and lower ends for blocking the plastic spring.

[0010] Implementing the above technical solution can prevent the plastic spring from penetrating deeply into the waste toner bin of the photosensitive drum.

[0011] Furthermore, the diameter of the annular portion of the plastic spring is smaller than the diameter of the powder outlet hole of the photosensitive drum.

[0012] Implementing the above technical solution facilitates the plastic spring to pass through the powder outlet hole of the photosensitive drum.

[0013] Furthermore, the surface of the plastic spring is covered with a sponge cover or a brush cover.

[0014] Implementing the above technical solution can improve the plastic spring's ability to carry waste powder.

[0015] Furthermore, the pulling mechanism includes a plastic wire, which is located outside the photosensitive drum and connected between the two blocking blocks.

[0016] Implementing the above technical solution makes it easy to remove the two blocking blocks together.

[0017] Furthermore, a hand buckle groove is provided on the photosensitive drum on one side of the plastic line for inserting fingertips.

[0018] The implementation of the above technical solution makes it easier for workers to pinch the plastic wire with their fingertips.

[0019] The technical effects and advantages of this utility model are:

[0020] 1. The utility model uses the pulling of two blocking blocks to drive the plastic spring to move and deform in the waste toner bin of the photosensitive drum, thereby driving the waste toner to move to the toner outlet hole of the photosensitive drum for discharge.

[0021] 2. Compared with the prior art, the device of the utility model improves the fluidity of waste powder through the activity of the plastic spring, making it less likely to be blocked. At the same time, there is no need to beat the photosensitive drum to avoid loosening of the installation position of some parts. BRIEF DESCRIPTION OF THE DRAWINGS
