Problems solved by technology

[0002] In order to prolong the service life of rollers used in printers and copiers, the rubber used on PFA sleeves has stronger mechanical strength and anti-deterioration performance than ordinary rubber, but at the same time, this rubber has higher shrinkage than ordinary rubber. However, ordinary PFA casing film cannot achieve the shrinkage matching this rubber, so the rubber and ordinary PFA casing film will shrink in different magnitudes when vulcanized at 150°, thus forming wrinkles on the surface of the rubber. affect product quality

Abstract

The invention discloses a PFA (Poly Fluoro Alkoxy) casing pipe extending device and method. The PFA casing pipe extending device comprises a taking and feeding mechanism, a heating furnace and a taking and recovering mechanism, wherein the heating furnace is positioned and arranged between the taking and feeding mechanism and the taking and recovering mechanism; the taking and feeding mechanism, the heating furnace and the taking and recovering mechanism commonly form a path for feeding, heating and recovering a PFA casing pipe; and the taking and feeding mechanism and the taking and recovering mechanism have different taking speeds. According to the PFA casing pipe extending device and method, a thin film of the PFA casing pipe with rubber can synchronously contract when a product is heated and cured, so that wrinkles on the surface of the product are removed, and the product quality is improved.

Description

technical field [0001] The invention relates to the field of extension devices, in particular to a PFA casing extension device and an extension method thereof. Background technique [0002] In order to prolong the service life of rollers used in printers and copiers, the rubber used on PFA sleeves has stronger mechanical strength and anti-deterioration performance than ordinary rubber, but at the same time, this rubber has higher shrinkage than ordinary rubber. However, ordinary PFA casing film cannot achieve the matching shrinkage of this rubber, so the rubber and ordinary PFA casing film will shrink in different magnitudes when vulcanized at 150°, thus forming wrinkles on the surface of the rubber. affect product quality. Contents of the invention [0003] In order to overcome the above defects, the present invention provides a PFA sleeve stretching device and its stretching method. The stretching device has a simple structure and can shrink the PFA sleeve film synchron...
