Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a dust removal protection device for laser printers, which solves most of the problems by using external brushes to clean, but this operation cannot clean the fine dust at the corners. Cleaning, if the dust is not removed frequently, the printer is easily blocked during the printing process, which will affect the normal operation of its work

Abstract

The invention discloses a dedusting and protective device for a laser beam printer. The dedusting and protective device comprises a lower shell body, a cooling fan and a shielding cover. The lower shell body is connected with an upper shell body in a threaded mode through a bolt piece, and the cooling fan is arranged on the surface of the back end of the upper shell body. A hollow groove is reserved on the surface of the front end of the upper shell body, and the shielding cover is fixed to the surface of the front end of the lower shell body. A printer body is fixed to the front end of a buntpiece, a paper inlet is reserved at the upper end of a cover body, and a limiting plate is fixed on the lower side of the back end of the paper inlet. According to the dedusting and protective devicefor the laser beam printer, the bunt piece inside the lower shell body can limit and fix the inner printer body to form a cavity to facilitate the air flow inside the device. Cross-ventilation is formed inside the device and accelerates the air flow inside the shell body. The device not only stabilize and fix the inner printer body, but also plays an all-round protective effect, so that the damage of the inner printer caused by external collision is avoided, and the amount of dust adsorption is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of printers, in particular to a dust removal protection device for laser printers. Background technique [0002] Laser printers were born out of the laser phototypesetting technology in the late 1980s and became popular in the mid-1990s. It is a printout device that combines laser scanning technology and electrophotography technology. Its basic working principle is the binary data information sent by the computer. , converted into a video signal by the video controller, and then the video signal is converted into a laser drive signal by the video interface or control system, and then the laser beam carrying the character information is generated by the laser scanning system, and finally the laser beam is imaged by the electrophotographic system and Transfer to paper. [0003] During the printing process, the inner cavity of the machine is very easy to be adhered by dust and fine paper scraps. Most of the so...
