Description
Technical Field
The invention relates to the technical field of printer assembly, in particular to an assembly device for assembling a fluorine sleeve mold cylinder and a PFA fluorine sleeve and a use method thereof.
Background
The fixing device is a component part of the printer, and when the paper with the ink passes through the fixing device, the ink is melted by heat and permeates into the paper, so that the fixing is realized. The fixer includes an upper roller, which mainly serves to provide heat for melting ink. The upper roller comprises a fixing roller and a fixing film, and the main difference between the fixing roller and the fixing film is that the heating source is different, but the upper roller and the fixing film are the same in that the upper roller comprises a hollow tube and a PFA fluorine sleeve sleeved outside the hollow tube.
Further, as shown in fig. 1-2, the FPA fluorine sheath 2 is a thin film which is long and has two open ends; in addition, the FPA fluorine sleeve has certain elasticity and certain viscosity, so that the FPA fluorine sleeve can be adhered to another object after being expanded.
When assembling the hollow tube and the PFA fluorine sheath, the PFA fluorine sheath is usually expanded by the fluorine sheath mold because the PFA fluorine sheath has an inner diameter smaller than the outer diameter of the hollow tube when it is not expanded. The fluorine sleeve mold cylinder is a mold manufactured according to the FPA fluorine sleeve and is used for adhering the expanded FPA fluorine sleeve; as shown in fig. 3, the fluorine sleeve mold cylinder 3 comprises an integrally formed middle cylinder 30 and side cylinders 31 respectively positioned at two ends of the middle cylinder, wherein the inner diameter of the middle cylinder is the same as that of the side cylinders, and the outer diameter of the middle cylinder is larger than that of the side cylinders. During the equipment, after the adhesion of FPA fluorine cover is in the fluorine cover mould section of thick bamboo, insert the inside of fluorine cover mould section of thick bamboo with the hollow tube, and then peel off the FPA fluorine cover from the fluorine cover mould section of thick bamboo, the FPA fluorine cover that is in the expansion state can rebound naturally, closely attach on the outer wall of hollow tube, can accomplish the installation of hollow tube and FPA fluorine cover.
At present, for expansion of the PFA fluorine sheath, an air bag is often plugged into the PFA fluorine sheath, and the air bag is inflated to expand the PFA fluorine sheath, however, in this way, the problem of low yield and low production efficiency is easily caused by rupture of the PFA fluorine sheath due to uneven force application to the PFA fluorine sheath.
Therefore, a new assembling device is still needed to be designed to improve the yield and the production efficiency of assembling the PFA fluorine sheath.
