Abstract

The invention relates to a trimming knife after film coating of a plastic product film coating combination machine, comprising a rack, an upper blade, a lower blade, a blade adjusting mechanism and a driving mechanism, wherein the upper blade and the lower blade are disc-shaped and are respectively arranged on the rack by an upper knife rest and a lower knife rest; an elastic blade adjusting device for adjusting the blades is also arranged between the lower blade and the lower knife rest and comprises at least three springs; the lower knife rest is provided with hole grooves for installing the springs; and the springs are arranged in spaces formed by matching of the hole grooves and the lower blade and are in a compressed state. The trimming knife has the advantages that the distance between the upper blade and the lower blade is adjusted by the elastic blade adjusting device, so that the upper blade and the lower blade are attached together all the time, and further the problem of film-coating material burrs or incomplete cutting caused by separation of the upper blade and the lower blade is solved.

Description

technical field [0001] The invention relates to an edge trimming knife for a film-coating composite machine for plastic products. Background technique [0002] Plastic woven bags are currently widely used as a packaging material for fertilizers, chemical products, agricultural products and other items. Its main production process is to use plastic raw materials to extrude film, cut, and unidirectionally stretch into flat yarn, and then weave warp and weft to obtain products, which are generally called woven bags. When packing some special items, there are moisture-proof and waterproof requirements. It is necessary to coat a layer of waterproof material on one or both sides of the woven bag. The film-coating compound machine uses polypropylene and polyethylene woven cloth as the base material. Plastic-coated composite, paper-plastic composite, or pressure-bonded with color-printed OPP and CPP films, cut and sewed to make cylindrical paper-plastic or color-film composite pack...
