Tool for rapidly replacing carbon powder for selenium drum

Abstract

The invention relates to a tool for rapidly replacing carbon powder for a selenium drum. The tool comprises a cross rod arranged in the length direction of the selenium drum, wherein a thimble used for ejecting an iron pin on the selenium drum is arranged at the end part of the cross rod and matched and connected with the cross rod in a sliding and guiding manner; the thimble is consistent with the length direction of the cross rod, and the outer end of the thimble extends to the outer side of the cross rod; a regulating mechanism used for regulating the thimble to move in the length direction of the cross rod is arranged on the cross rod and connected with the inner end of the thimble. According to the technical scheme, the thimble is regulated by the regulating mechanism to move in the length direction of the cross rod so as to rapidly and conveniently eject the iron pin, so that the dismounting speed of the selenium drum is increased, and the rapid replacement and addition of carbon powder are realized.

Description

technical field [0001] The invention relates to the field of printing equipment, in particular to a tool for rapidly replacing carbon powder of a toner cartridge. Background technique [0002] HP HP1020 printer has the advantages of good printing quality, fast printing speed, not easy to jam, small size, etc., so it is widely used in life and office. The toner cartridge model used by the HP1020 printer is Q2612a. This toner cartridge has a large capacity, but it also has the defect of complicated powder adding operation. This type of toner cartridge includes a toner bin, a waste toner bin, a photosensitive roller, a magnetic roller, and a fixing assembly. Mounting feet 22 are arranged at both ends of the toner bin, and a second through hole is opened on the installation leg 22. The two ends of the waste toner bin are respectively Set the fixing piece, the fixing piece is provided with a vacancy for the installation foot to insert, the fixing piece (inner and outer fixing pa...

AI Technical Summary

Problems solved by technology

Since the opening of the jaw between the powder bin and the waste powder bin is less than a punch after the maximum opening, the iron pins are arranged perpendicular to the depth of the jaws, and the iron pins are located at the innermost end of the jaws, at a distance from the mouth of the jaws. The distance is greater than 14cm, the diameter of the iron pin is only about 2mm, and the end of the iron pin is generally partially covered by the scraper 20b on the waste toner bin. Therefore, it is very difficult and extremely difficult to use a screwdriver or iron wire to push out the iron pin 20a. It is laborious, especially when the iron pin is tightly clamped in the through hole

During the actual operation, the applicant sometimes needs to spend one or two hours to remove the iron pin
