Description

Technical Field

[0001] This utility model relates to the field of toner cartridge manufacturing technology, and in particular to a scraper powder coating device for toner cartridge manufacturing. Background Technology

[0002] A toner cartridge, also known as a photosensitive drum, is generally composed of an aluminum base material and a photosensitive material coated on the base material. In laser printers, over 70% of the imaging components are concentrated in the toner cartridge, and the print quality is largely determined by the toner cartridge. During toner cartridge production, there is a process of applying lubricating powder to the doctor blade. The doctor blade is often composed of a metal frame and a polyurethane sheet. Currently, toner cartridge production often uses a manual method to apply lubricating powder to the polyurethane sheet. However, this manual application method can easily lead to uneven distribution of the lubricating powder. Too much lubricating powder will cause it to fall onto the surface of the toner cartridge, affecting print quality; too little lubricating powder will affect the lubrication effect. Furthermore, manual operation is inefficient.

[0003] CN217821262U discloses a scraper powder coating device for toner cartridge production, including a workbench and a connecting seat. A protective cover is fixedly connected to the top outer side of the workbench, and a powder storage box is fixedly connected to the top middle of the workbench. A lifting mechanism is fixedly installed at the top middle of the protective cover, and a mounting frame is fixedly connected to the output end of the lifting mechanism. Circular grooves are opened at corresponding positions on the inner side of the mounting frame. Circular plates are fixedly connected to both sides of the connecting seat, and the circular plates are inserted into the inside of the circular grooves. A vibration mechanism is fixedly installed on the right side of the mounting frame.

[0004] In use, the existing device can only feed the next batch of scrapers after one batch of scrapers has finished being coated with powder, which results in low work efficiency and long waiting time. Therefore, we have proposed a scraper powder coating device for toner cartridge production. Utility Model Content
