Description

Technical Field

[0001] This invention relates to the field of fuser film production technology, and in particular to a production line and production process for printer fuser film. Background Technology

[0002] Fusing film is a special high-temperature resistant film used in copiers or printers for fixing images during copying or printing. Fusing is the process of fixing the unstable, erasable toner image on the copy paper onto the paper. Generally, the toner is melted by heating the fusing unit and then penetrates deep into the paper fibers, resulting in the copying or printing effect.

[0003] like Figure 2 As shown, the basic structure of the fixing film 1 is an inner stainless steel blank 11, a middle silicone film 12, and an outer fluorine protective sleeve 13. The silicone film 12 is formed by heating and solidifying liquid silicone material on the surface of the stainless steel blank 11. The traditional silicone film molding adopts the injection process, that is, liquid silicone material is injected between the stainless steel blank 11 and the mold by pressurization. However, the injection process has the following defects: (1) There is a minimum limit on the thickness of the adhesive layer. The silicone film cannot be less than 0.3mm. Because the smaller the gap of the silicone film, the greater the pressure required to inject the liquid silicone, and the higher the pressure resistance requirement of the mold. (2) The inner stainless steel blank is prone to deformation and pitting when subjected to the pressure of injection. (3) The injection is prone to uneven glue distribution, and the formed silicone film is thick on one side and thin on the other, which is not uniform. (4) The fluidity of the colloid decreases under high pressure, so there are certain requirements for the concentration of liquid silicone material. (5) The production efficiency is low and the injection speed is slow.

[0004] In addition, the outer fluorine protective sleeve is a transparent finished cylindrical film. The fluorine protective sleeve and the silicone film should be tightly bonded. However, in the existing production process, the cost of auxiliary sleeve equipment is relatively high, which increases the product cost. Summary of the Invention
