Description

TECHNICAL FIELD

[0001] The utility model relates to carbon powder box technical field especially relates to a carbon powder box convenient to full inspection and automatic film removal. BACKGROUND

[0002] In the current compatible selenium drum market, most products adopt the design of manually tearing off the sealing film, and the customer needs to manually pull out the sealing film from the powder outlet of the powder tank before use, which not only increases the steps before use and affects the experience satisfaction, but also the carbon powder adhered to the surface of the sealing film is easy to diffuse into the air during the film tearing process, causing environmental pollution and health hazards. In addition, the carbon powder box often needs to be fully detected before leaving the factory to ensure the qualified rate. The present application solves the problem of manually tearing off the sealing film by connecting the sealing film with the stirring frame, but the stirring frame gear needs to be removed before detection to avoid the stirring frame rotating during the test process, which causes the sealing film to be accidentally torn off. Therefore, the selenium drum mounting gear needs to be disassembled again after the detection is qualified, which seriously reduces the production efficiency, increases the labor and material costs, and repeated disassembly and assembly easily causes secondary pollution of the parts, causing printing quality problems.

[0003] In addition, the traditional sealing film structure adopts simple roll-shaped plastic film welding or bonding on the outside of the powder outlet of the powder tank, and the sealing film is directly discarded after being torn off, which cannot be reused, causing resource waste. The connection strength between the sealing film and the powder tank is greatly affected by the batch difference of the material. When the welding strength is insufficient, it is easy to fall off during transportation, and when the strength is too high, it is difficult to tear off the film or the film is broken, affecting the normal opening of the powder outlet. At the same time, the existing design needs to additionally weld PET stirring blades on the stirring frame to stir the carbon powder, further increasing the production process and cost.

[0004] Therefore, a new type of carbon powder box structure that takes into account the full detection efficiency, automatic film tearing function and film reuse is needed to solve the problems of low production efficiency, complicated operation, resource waste and environmental pollution in the prior art.
