Embodiment Construction

[0027] The invention discloses a method for manufacturing a Teflon film-coated silicone rubber fixing heating roller. First, a fluorine sleeve 3 is placed on the outer peripheral surface of an aluminum tube 4 , and then a silicone layer is injected between the aluminum tube 4 and the fluorine sleeve 3 . The fluorine sleeve 3 is made of a cylindrical Teflon film.

[0028] The concrete steps of manufacturing method of the present invention are described as follows:

[0029] The first step, the assembly of the fluorine sleeve and the aluminum tube:

[0030] see figure 1 and figure 2 , shown in the middle is an aluminum tube 4, the aluminum tube 4 is covered with a fluorine sleeve mold 5, between the aluminum tube 4 and the fluorine sleeve mold 5 is a fluorine sleeve 3, and the fluorine sleeve 3 is obtained from Ordered directly from the manufacturer. The outer diameter of the fluorine sleeve 3 is smaller than the outer diameter of the aluminum tube 4, so the aluminum tube 4 ...

Abstract

The invention relates to a method for manufacturing a fixing heating roller coated with teflon film silastic, comprising the following steps of: firstly, sheathing a fluorin jacket on the peripheral surface of an aluminium tube, and then infusing a silica gel layer between the aluminium tube and the fluorin jacket. The fluorin jacket is made of tubular teflon films. The invention has the advantages of simpler process, simple equipment, easy operation and low cost; and the manufactured fixing heating roller has high chemical stability and is suitable for high-speed printers and copiers.

Description

technical field [0001] The invention relates to a production process of a fixing heating roller in a fixing system of a printer and a copier, and more particularly relates to a process method for coating a Teflon (Teflon) film and silicon rubber on the surface of the fixing heating roller. Background technique [0002] The fixing systems of modern printers and copiers all adopt the hot-press fixing method, and the fixing heating roller is an important part of it. The traditional process method is to directly spray Teflon coating on the surface of the aluminum tube to ensure the quality of printing or copying, and to prevent the toner on the printer or copier from adhering to the surface of the fixing heating roller during the fixing process. Keep paper clean and clear. The advantage of this method of fluorine coating is that it is easy to process, no adhesive is needed, and only the fluorine material needs to be melted at high temperature, but its disadvantages are also obv...
