Powder addition tool of cartridge

Abstract

The invention relates to a powder addition tool of a cartridge. The powder addition tool comprises a working segment, a connection segment and a handheld segment, wherein the connection segment is arranged between the working segment and the handheld segment, the projection of the working segment on a plane A is projection A, the plane A is a plane perpendicular to a direction f, the direction f is a tool height direction, the projection of the handheld segment on the plane A is projection B, the projection A is a polygon, the projection B is arranged in an external circle of the projection A, each side surface of the working segment is arranged in a groove shape, and the groove length direction of the groove shape is consistent with the direction f. In the scheme, when the tool is inserted into a novel carbon powder bottle for adding carbon powder into the cartridge, the problem of carbon powder plug can be effectively solved, and the problem of pollution and waste caused by leakage during carbon powder addition is prevented.

Description

technical field [0001] The invention relates to the field of printing equipment and consumables, in particular to a toner cartridge refilling tool. Background technique [0002] Toner in the printer is stored in the toner cartridge. The toner cartridge, also known as the photosensitive drum, is generally composed of a base material made of aluminum and a photosensitive material coated on the base material. Toner needs to be added to the toner cartridge or the toner cartridge needs to be replaced. Due to the high cost of the toner cartridge, the toner cartridges currently on the market are mainly toner cartridges that can be refilled many times. The operation of adding toner cartridge mainly includes opening the toner outlet on the waste toner bin, pouring out the waste toner completely in the waste toner bin, then closing the toner outlet on the waste toner bin, and then opening the toner inlet on the toner bin, Pour new toner into the toner bin from the toner inlet, and ...

AI Technical Summary

Problems solved by technology

However, during the process of pulling out the toner bottle, rotating it upright and inserting the toner bottle upside down into the toner bin again, due to the change in the attitude of the toner bottle, the state of the toner powder is easily rushed out of the toner nozzle and falls on the surface of the toner drum. In the hands of the operator and on the workbench

Therefore, cause the waste of toner and also need to carry out a large amount of cleaning work after adding powder

[0005] Although some documents disclose some easy-to-powder toner bottles at present, there are two main schemes adopted: the first scheme is to improve the powder-filling head, and a complicated material guide mechanism is set in the powder-filling head , such as the spiral screw mechanism, for this scheme, because the toner is a consumable product, and the toner bottle is only a container for holding toner, and a complicated material guide mechanism is set in the powder feeding head, so that the toner bottle The cost increases, and the toner bottle is a disposable product, which greatly increases the printing cost of the printer. Moreover, the setting of the material guide mechanism occupies the section of the powder falling channel, which greatly reduces the speed of adding toner, and the toner will be damaged due to the guide mechanism. The existing part of the toner mechanism is accumulated in the toner head, so it is difficult to be promoted, and there is no sales of this kind of toner bottle in the market

The second solution is to install a toner feeder between the toner head and the bottle body when filling toner cartridges. Although this method can quickly add toner, after filling toner, the toner Part of the toner will remain in the toner, so the storage of the toner cartridge is complicated. If the storage is not good, the toner in the toner will be damaged when the toner is added next time.

At the same time, the operation of assembling and disassembling the powder feeder is complicated and needs to be connected to the electricity. It is still easy to cause the toner to be spilled on the hands of the operator during disassembly, so this solution has not been popularized and utilized in actual production.

[0006] Therefore, the easy leakage of added toner is a problem that has plagued toner operators since the promotion of easy-to-fill toner cartridges. There has been no feasible solution that can be widely promoted to solve the above problems.
