Double helix push type waste powder collection device

Abstract

The invention provides a double-screw propulsion type waste powder collection device, which includes a bottom shell, a main support unit and a transmission unit; the main support unit includes a main support, a powder drop port and a powder scraping shaft, and the main support is fixed on the On the bottom shell, the powder dropping port is set on the main bracket, the powder scraping shaft is set above the powder dropping port, and a scraper is arranged on the powder scraping shaft; the transmission unit includes sequentially connected Transmission device, powder feeding shaft and powder feeding device, the transmission device is arranged on the bottom shell. The invention has the beneficial effects of simple structure, convenient manufacture, automatic transfer of waste powder to the waste powder collection device, smooth operation, high cleaning efficiency, space saving, high stability and good sealing effect.

Description

technical field [0001] The invention belongs to the field of laser printer waste powder recovery equipment, and in particular relates to a double-screw propulsion type waste powder collection device. Background technique [0002] At present, laser printers have occupied an absolute market in the field of office equipment. As people's requirements for laser printers are increasing day by day, major laser printer manufacturers are also constantly upgrading their products. In the process of office printing, the most common problem is powder leakage when a large amount of printing occurs. The accumulation of waste toner becomes a lot, and there are no cleaning measures, which eventually causes waste toner to remain on the paper, resulting in a decline in printing quality. [0003] At present, there are problems in the waste toner recovery device of laser printers: 1. Most of them are integrated with the toner cartridge to directly clean the waste toner on the photosensitive dru...

Problems solved by technology

In the process of office printing, the most common problem is powder leakage when a large amount of printing occurs. The accumulation of waste toner becomes a lot, and there is no cleaning measure, which eventually causes waste toner to remain on the paper, resulting in a decline in printing quality

[0003] At present, there are problems in the waste toner recovery device of laser printers: 1. Most of them are integrated with the toner cartridge to directly clean the waste toner on the photosensitive drum, but there are few waste toner devices that specialize in cleaning the transfer belt; 2. Waste toner recovery device It takes up a lot of space, which makes the printer bulky; 3. The structure is complex, the mold development is difficult, and the process level is reduced
