Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of selenium drum cleaning, especially to a selenium drum waste powder bin. BACKGROUND

[0002] Selenium drum, also known as photosensitive drum, is a cylinder coated with organic material on the surface, which has a pre-charge. When light shines on, the part that is irradiated will have a resistance reaction. The data signal sent controls the emission of laser, and the light on the surface of the selenium drum changes constantly. Thus, some places are irradiated, the resistance becomes small, and the charge disappears. Some places are not irradiated, and still have charge. Ultimately, the surface of the selenium drum forms a latent image composed of charge. The carbon powder in the selenium drum is a fine resin particle with charge. When the charged surface of the selenium drum passes through the ink roller, the charged part absorbs the ink powder particles, and thus the latent image becomes a real image. While the selenium drum rotates during work, the printing system sends the printing paper, which has a charge with the same polarity as the surface of the photosensitive drum but much stronger. Then the paper passes through the selenium drum with ink powder, and the ink powder on the surface of the photosensitive drum is attracted to the printing paper, and the image is formed on the surface of the paper. The photosensitive drum is provided with a powder scraping plate to scrape off the waste powder on the surface of the photosensitive drum, so that the waste powder falls into the waste powder bin.

[0003] When using the above technology, it is found that the existing selenium drum waste powder bin has the following technical problems: the existing selenium drum waste powder bin needs to be disassembled and cleaned after a long time of use because a large amount of waste powder accumulates on the bin wall. At this time, the existing selenium drum waste powder bin usually needs to be disassembled, and the waste powder bin is effectively disassembled. Therefore, the selenium drum waste powder bin is not convenient, which affects the efficiency of disassembling the waste powder bin. Therefore, we design a selenium drum waste powder bin to provide another technical solution to the above technical problems. UTILITY MODEL CONTENT

[0006] Cross sliding rails are arranged at both ends of the carbon powder box, the cross guide blocks are slidably installed on the cross sliding rails, and the carbon powder box is provided with a disassembly mechanism for positioning the cross guide blocks.

[0007] Further, the dismounting mechanism comprises a limiting sheet, a spring and a lever, and both ends of the toner cartridge are provided with limiting grooves, and the extending direction of the limiting grooves is perpendicular to the extending direction of the cross slide rail.

[0030] In the utility model, the toner cartridge 3 is installed on the side of the toner cartridge 1 close to the photosensitive drum 4 through the cooperation of the cross sliding rails 12 and the cross guide blocks 8, in use, the toner cartridge waste powder bin is assembled into the printer for use, at the moment, the toner is injected into the toner cartridge 1, the paper passes through the toner cartridge with toner, the toner on the surface of the photosensitive drum 4 is attracted onto the printing paper, thereby the paper is printed by transfer printing, in the use process, the waste powder falls into the toner cartridge, when the waste powder is filled in the toner cartridge 3, at the moment, the cross guide blocks 8 are released from the limiting through the dismounting mechanism, then the toner cartridge 3 is slid, so that the toner cartridge 3 is separated from the cross guide blocks 8 of the toner cartridge 1, thereby the toner cartridge 3 is dismounted from the toner cartridge 1, and the waste powder in the toner cartridge 3 is cleaned, therefore the dismounting effect and the cleaning convenience of the toner cartridge 3 are improved.

[0031] Further, the dismounting mechanism comprises a limiting piece 9, a spring 10 and a lever 11, the two ends of the toner cartridge 3 are further provided with limiting grooves, the extending direction of the limiting grooves is perpendicular to the extending direction of the cross sliding rails 12, one end of the spring 10 is fixed in the limiting groove, the other end of the spring 10 is fixedly connected with the limiting piece 9, and the lever 11 is fixedly installed on the limiting piece 9.

[0032] Further, the spring 10 is contracted to limit the limiting piece 9 in the limiting groove, and the spring 10 is reset to limit the limiting piece 9 in the cross sliding rail 12, thereby the cross guide blocks 8 are positioned.

[0033] Further, one side of the cross guide block 8, which faces the limiting piece 9, is provided with an arc, and the top of the cross sliding rail 12 is provided with an opening.
