Embodiment Construction

[0013] The content of the present invention is illustrated by the following examples.

[0014] The wear-resistant layer on the surface of the powder knife and its treatment process include the following steps: (1) Pretreatment: Use a non-woven fabric to dip in deionized water to clean the surface of the metal sheet of the powder knife to remove dirt; (2) Nano-coating Layer liquid preparation and pre-coating: First, the PVCCVD method is used to prepare nano-alumina spherical particles, the surface of which is coated with metal nickel, and the diameter after coating is about 100nm. Secondly, add a binder with a mass fraction of 70% to the above-mentioned nano-powder, fully stir and mix evenly, and use a brushing equipment to evenly coat the coating solution on the surface of the cleaned powder knife metal sheet; (3) laser cladding : Select the laser beam according to the area of ​​the coating to carry out the cladding process. In the present invention, the laser beam and the pow...

Abstract

The invention relates to a wear-resistant layer of a powder knife and a processing technology, wherein the wear-resistant layer is a nano coating layer, and the processing technology comprises the steps of: (1) cleaning the surface of a metal sheet of the powder knife; (2) coating a nano powered material on the surface of the cleaned powder knife and drying the nano powdered material; and (3) cladding the powder material by laser beams, protecting the powder material by inert gas, and cooling. The processing technology of the powder knife realizes cladding of the nano coating on the metal powder knife by utilizing the laser cladding technology, increases the wear resistance, and repairs the old powder knife.

Description

technical field [0001] The invention relates to a treatment process for the surface coating of a metal powder-discharging knife in a developing system of a printer and a copier, in particular to the coating of a nano-wear-resistant layer on the surface of a metal sheet on the powder-discharging knife. Background technique [0002] The powder knife is an important part of the toner cartridge of the laser printer. Its function is to control the toner delivered to the developing roller at a reasonable thickness to control the amount of toner; in addition, the powder knife is also used to give Toner charging. Therefore, the performance of the powder knife is very important to the printing quality. [0003] Commonly used powder knives have two materials. One is a rubber strip and the other is a metal sheet. Because the rubber is easy to deform when the temperature is high and it is easy to age after long-term use, etc., it is easy to produce uneven pressure distribution betwee...
