Laser printer powder bin self-weight powder coating equipment

Abstract

The invention relates to the technical field of printer powder bins, and further discloses laser printer powder bin self-weight powder coating equipment, which comprises a shell, wherein a placing groove is formed in the shell, a cushioning spring is movably connected to the interior of the placing groove, the bottom of the cushioning spring is movably connected with an elastic plate, feeding frames are fixedly connected to the positions, located on the two sides of the placing groove, in the shell, a constant-pressure groove is fixedly connected to the bottom of the placing groove in the shell, a movable plate is movably connected into the constant-pressure groove, supporting frames are fixedly connected into the shell and located on the left side and the right side of the movable plate,reciprocating springs are movably connected to the upper side and the lower side of a rotating shaft, limiting pipes are movably connected into the supporting frames and located on the surfaces of thereciprocating springs, and deformation bags are fixedly connected to the surfaces of the limiting pipes. According to the invention, the compressed telescopic rod stretches out and draws back to help the carbon powder to move, and the carbon powder in the shell falls into the constant-pressure groove, so that the effects that automatic powder adding is conducted according to the pressure of thecarbon powder, and paper waste is avoided are achieved.

Description

technical field [0001] The invention relates to the technical field of printer powder bins, in particular to a self-weight powder coating device for a laser printer powder bin. Background technique [0002] Printer consumables are divided into original brand consumables and compatible consumables or general consumables. Printer consumables refer to consumable products used by printers; The bin is a relatively common part in the printer, especially when used in conjunction with the modern product laser printer, it provides the printing effect. [0003] Most of the existing powder bins are installed inside the printer, and in order to prolong the working time of the printer, the volume of the powder bins is set larger, but it is still unavoidable to open the printer to add powder, and the existing technology is not suitable for adding powder. The timing is often judged by the effect of the printed paper, which leads to excessive blank paper or paper that fails to print during...

Problems solved by technology

[0003] Most of the existing powder bins are installed inside the printer, and in order to prolong the working time of the printer, the volume of the powder bins is set larger, but it is still unavoidable to open the printer to add powder, and the existing technology is not suitable for adding powder. The timing is often judged by the effect of the printed paper, which leads to too much blank paper or paper that fails to print during the printing process. Therefore, a self-weight powder coating equipment for laser printers comes into being.
