Novel efficient printer magnetic roller structure and mounting bearing

Abstract

The invention relates to the technical field of printers, and discloses a novel efficient printer magnetic roller structure and a mounting bearing. The novel efficient printer magnetic roller structure comprises a magnetic core, the outer side of the magnetic core is movably connected with a pressing plate, the outer side of the pressing plate is movably connected with a first buffer plate, and through cooperation of a control rod, a connecting piece, the first buffer plate and the pressing plate, the magnetic core is fixed; a magnetic roller body is mounted in a printer through positioning of a mounting shaft on the outer side of a mounting column, a positioning screw hole and a clamping block, a protection plate is fixed to the outer side of the magnetic roller body through a spring lock, pollution of electrified carbon powder on the magnetic roller body to a selenium drum is prevented, and meanwhile, the spring lock can be opened, cleaning and maintenance of the protection plate and the magnetic roller body are facilitated; through cooperation of a buffer block, an inclined rod, a sliding block, a bearing seat and a second buffer plate, the influence of vibration on the magnetic roller body is diluted and reduced, the stability of the magnetic roller body is kept, the problems of uneven adsorption of carbon powder, uneven and fuzzy printing color blocks and the like are solved, and the printing quality is further improved.

Description

technical field [0001] The invention relates to the technical field of printers, in particular to a novel high-efficiency printer magnetic roller structure and mounting bearings. Background technique [0002] There is a magnetic roller inside the printer. The magnetic roller is generally composed of a magnetic core, a bracket, a conductive wire and a magnetic sleeve. The function of the magnetic roller is to absorb the toner, charge the toner, and then pass the opposite charge of the drum core to absorb When pushed, a toner image is formed on the drum. [0003] The magnetic rollers of existing printers generally have complex structures, are difficult to replace and clean, and lack shock absorbing devices, and the vibration of the magnetic rollers during printing makes the carbon powder absorb unevenly, and the printed content has problems such as uneven color blocks and blurring. [0004] In order to solve the above problems, the inventor provides a new high-efficiency prin...
