Mechanical lubrication device for toner cartridge scraping knife

Abstract

The invention provides a mechanical lubrication device for a toner cartridge scraping knife. The mechanical lubrication device comprises a base and a transversal plate, wherein a groove is formed in the center of the upper surface of the base; slide blocks are arranged at the left side and the right side of the groove; the upper ends of the slide blocks are fixed to the lower end of an electric telescopic rod; a lubricant powder storage box is formed in the central position of the upper surface of the transversal plate; a box cover is arranged at the upper end of the lubricant powder storage box; a filter screen is arranged at the bottom of the lubricant powder storage box; sealed scraping sheets are arranged below the filter screen; two groups of the sealed scraping sheets are arranged, and symmetrically distributed at the two sides below the center line of the filter screen; the surfaces of the sealed scraping sheets are in contact connection with a powder coating rolling wheel; thesealed scraping sheets are hinged to a hinge shaft; the hinge shaft is fixed to the middle position of the inner wall of a fixing plate; the fixing plate is welded to the lower end of the lubricant powder storage box; and the powder coating rolling wheel is fixed to the outer side of a rolling shaft. The mechanical lubrication device provided by the invention is simple in structure and convenientto use; the sealed scraping sheets are arranged on the fixing plate, and capable of sealing the lubrication device, so that lubricant powder can be saved.

Description

technical field [0001] The invention relates to the technical equipment field of toner cartridge production, in particular to a mechanical lubricating device for a toner cartridge scraper. Background technique [0002] In the production process of toner cartridges, there is a process of applying lubricant powder with a scraper. However, at present, toner cartridge manufacturers use the following methods to complete the coating of lubricating powder: first, put some lubricating powder in a box, then put the scraper directly into the box, make the rubber part of the scraper contact with the lubricating powder, and finally take it out The scraper, the lubricating powder will adhere to the scraper, thus lubricating the scraper. [0003] This existing lubricating powder coating method is extremely uneven, and the amount of lubricating powder adhering to the scraper cannot be controlled. When the amount is too large, the lubricating powder will fall to the surface of the toner dr...

Problems solved by technology

[0003] This existing lubricating powder coating method is extremely uneven, and the amount of lubricating powder adhering to the scraper cannot be controlled. When the amount is too large, the lubricating powder will fall to the surface of the toner drum and affect the appearance, and falling to other parts will cause printing quality and volume. If the scraper is too small, the scraper will not be able to provide enough lubrication, which will also affect the quality of the product; and the lubricating powder is exposed in the box, because the particles of the lubricating powder are very small, it is easy to float into the air, thus affecting the workshop. production environment, and most of the existing lubricating devices require workers to manually operate, and the arm is very tired after a long time
