Problems solved by technology

The surface smoothness of the existing heating roller can no longer meet the requirements of tiny carbon powder
During use, toner will gradually accumulate in the pits and gaps of the surface coating, and eventually leave traces on the paper, commonly known as sticky powder, which will affect the printing and copying effect

Embodiment Construction

[0021] Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in further detail:

[0022] As shown in the figure, a fixing mechanism of a printer, a copier, and an all-in-one machine includes a heating roller 1 and a pressure roller 2, and the pressure roller 2 is arranged below the heating roller 1 in parallel. The paper gap 3, the heating roller 1 is connected with a heating source, the heating roller 1 is made of metal, resin or ceramic material, and the metal material includes commonly used copper, aluminum, iron and stainless steel, etc. The outer diameter of the heating roller 1 and the roller body 11 is preferably 29.5-30.5mm , the wall thickness of the roller body 11 is preferably 1 mm; the surface of the heating roller 1 is covered with a resin film cover 12, and the material of the resin film cover 12 is a fluororesin such as PFA or PTFE, and the resin film cover 12 completely covers the working surface of the hea...

Abstract

The invention relates to a printer, copier and multifunctional integrated machine fixing mechanism and a processing technology of a heating roller thereof. According to the printer, copier and multifunctional integrated machine fixing mechanism and the processing technology of the heating roller thereof, a resin sleeve film is used and replaces an existing coating, so that the smoothness and the roughness of the heating roller surface can be effectively ensured; the easy abrasion caused by the grinding process in the prior art can be avoided, so that the service life of the product can be prolonged; meanwhile, the surface of the resin sleeve film is smooth and free from a gap, so that the release property is ideal, and as a result, the carbon powder attaching is completely avoided, and the powder adhering is prevented; the fluororesin sleeve film is high in heat conductivity and abrasion resistance, so that the energy is saved, and the service life of the heating roller is prolonged.

Description

technical field [0001] The invention relates to the field of printers and duplicators, in particular to a processing technology for fixing mechanisms of printers, duplicators, multifunctional all-in-one machines and heating rollers thereof. Background technique [0002] Existing printers, photocopiers fix the toner on the paper by a practical fixing mechanism. The existing fixing mechanism includes a pressure roller and a heating roller. The surface of the heating roller is usually coated with a coating, and the coating is polished to enhance thermal conductivity and surface smoothness. The top layer of the coating is thinned, which affects the service life, and there will still be microscopic gaps and pits on the surface of the polished coating. With the development of toner for printers and copiers, toner tends to be smaller, and the toner particles are getting smaller and smaller. The surface smoothness of the existing heating roller can no longer meet the requirements ...
