Description

Technical Field

[0001] The utility model relates to the technical field related to selenium drums, in particular to a selenium drum detection mechanism. Background Art

[0002] The existing toner cartridge detection mechanism is: Figure 1 As shown, it includes a photosensitive drum placement position, a printer control host, a charging roller A1 distributed around the photosensitive drum placement position, a laser emitter A2, a transfer roller A3, a waste powder scraper A4, a magnetic roller A5 and a driving device for driving the photosensitive drum A6 to rotate. The charging roller is used to charge the photosensitive drum placed on the photosensitive drum placement position so that a uniform layer of charge is distributed on the surface of the photosensitive drum. The laser emitter receives image signal information from the printer control host to expose the surface of the photosensitive drum, causing a potential difference on the surface of the photosensitive drum. The toner on the surface of the magnetic roller is attracted by the charge on the surface of the photosensitive drum and jumps to the surface of the photosensitive drum to fill the potential difference, so that a toner image is formed on the surface of the photosensitive drum. The transfer roller A3 of the printer transfers the toner image on the surface of the photosensitive drum to the surface of the printing paper A7, which is then fixed by the printer to form a paper image. Then, the worker visually identifies the paper image and compares it with the image to be printed to determine whether the toner drum (i.e., the photosensitive drum) is qualified. Such detection efficiency is low, and there is a certain error in human eye recognition detection, which can easily lead to unqualified toner drums entering the market. Utility Model Content

[0003] In order to overcome the existing technical defects, the purpose of the present utility model is to provide a toner cartridge detection mechanism to solve the above technical problems.

When the photosensitive drum is placed in the placement position on the support frame, the gear at the end of the photosensitive drum is engaged with the gear at the motor driving end.

[0019] The charging roller 2 is arranged above the left side of the photosensitive drum placement position and is used to charge the photosensitive drum 1 placed in the photosensitive drum placement position.

[0020] The laser emitter 3 is arranged above the right side of the photosensitive drum placement position, and the emitting end of the laser emitter 3 is facing the photosensitive drum placement position. The laser emitter 3 is electrically connected to the printer control host. The printer control host is used to store the picture image to be printed and convert the picture image information into image signal information and transmit it to the laser emitter 3. The laser emitter 3 is used to receive the image signal information transmitted by the printer control host to expose the surface of the photosensitive drum 1 placed at the photosensitive drum placement position, so that a potential difference occurs in the potential of the surface of the photosensitive drum 1.

[0021] The waste toner scraper 5 is arranged on the left side of the photosensitive drum placement position, and a waste toner bin 7 is arranged below the waste toner scraper 5 . The waste toner bin 7 is used to receive the waste toner scraped off by the waste toner scraper 5 .
