Description

Technical Field

[0001] The utility model relates to the technical field of printer equipment, in particular to a toner cartridge capable of collecting waste toner. Background Art

[0002] A printer is one of the output devices of a computer, used to print the results of computer processing on relevant media. There are many types of printers. According to the structure of printed characters, they are divided into full-width character printers and dot-matrix character printers. According to the way a line of characters is formed on paper, they are divided into serial printers and line printers. The toner cartridge is an important part of the printer. The toner cartridge covers the surface of the paper with toner powder, and then through a series of steps, the toner powder is fixed on the surface of the paper to form the required pattern on the surface of the paper.

[0003] The working principle of the toner cartridge is: after receiving the data to be printed, the toner in the cartridge is sucked out by the magnetic roller and then laid out on the photosensitive drum, which then prints the toner on the paper. After printing, the photosensitive drum will absorb the residual toner on its surface, as well as dust, paper scraps and other impurities, which will affect the subsequent printing quality. Therefore, a cleaning scraper is often set to scrape the waste toner on the photosensitive drum and collect it in the waste toner bin.

[0004] However, since there is a space between the waste toner bin and the photosensitive drum, waste toner can easily flow back, causing toner to adhere to the outer surface of the roller, which will produce ghosting and prevent normal printing. Utility Model Content

[0026] Through the above structure, the rotatable upper scraper 7 and the lower scraper 8 can be attached to and separated from the photosensitive drum 2, scraping up the waste powder and debris on the surface of the photosensitive drum 2 and storing them in the waste powder bin, so that the printer can operate normally.

[0027] Embodiment 2

[0028] Based on Example 1, please refer to the attached Figure 4

[0029] A feeding port 9 is provided on the upper side wall of the toner bin of the box body 1 away from the photosensitive drum 2 , and a discharging port 10 is provided on the vertical side wall of the waste toner bin of the box body 1 away from the photosensitive drum 2 .

[0030] Through the above structure, the feed port 9 is arranged at the top to facilitate feeding, and the discharge port 10 is arranged on the vertical side wall to facilitate dumping during discharge and avoid backflow of waste powder.

[0031] The front end of the box body 1 is provided with a rotating motor 11 connected to the upper scraper 7 and the lower scraper 8 respectively.

[0032] Through the above structure, the rotating motor 11 can be controlled by the controller, and the rotation of the upper scraper 7 and the lower scraper 8 is more flexible.

[0033] The lower scraper 8 is inclined upward toward the side close to the photosensitive drum 2, and the horizontal end of the upper scraper 7 is inclined upward toward the side close to the photosensitive drum 2; the horizontal end of the upper scraper 7 is a concave curved surface structure that cooperates with the photosensitive drum 2, and the end of the lower scraper 8 close to the photosensitive drum 2 is a convex curved surface structure; the lower end of the lower scraper 8 is in contact with the lower surface of the box body 1, and the lower surface of the waste toner bin of the box body 1 located on the left side of the lower scraper 8 is inclined upward toward the lower scraper 8.

[0034] Through the above structure, the upper scraper 7 and the lower scraper 8 cooperate with the photosensitive drum 2. The ends of the upper scraper 7 and the lower scraper 8 close to the photosensitive drum 2 are inclined upward toward the photosensitive drum 2 and can rotate, which can prevent the waste powder from flowing back, so that the printer can operate normally while collecting the waste powder.

[0035] It is worth noting that the supporting power supply and control switch of the rotating motor 11 mentioned in this embodiment can also be provided by the manufacturer. The circuits, electronic components and modules involved are all existing technologies and can be fully implemented by those skilled in the art without further explanation.

In the initial state, the upper scraper 7 and the lower scraper 8 of the cleaning mechanism 3 are not in contact with the photosensitive drum 2. The toner in the toner bin is sucked out by the magnetic roller 4 and then arranged on the photosensitive drum 2, and then the photosensitive drum 2 prints the toner onto the paper. After printing, the photosensitive drum 2 will absorb the residual toner on its surface, as well as dust, paper scraps and other impurities. The controller controls the rotating motor 11 to rotate the upper scraper 7 and the lower scraper 8 until they are in contact with the photosensitive drum 2, and the waste powder and debris on the surface of the photosensitive drum 2 are scraped up and stored in the waste powder bin, so that the printer can operate normally. The upper scraper 7 and the lower scraper 8 are inclined upward toward the photosensitive drum 2 at one end close to the photosensitive drum 2, which can avoid the waste powder from flowing back, so that the printer can operate normally for a long time while collecting the waste powder.
