Plastic woven bag film coating compound machine

Abstract

The invention relates to a plastic woven bag film coating compound machine which comprises a rack, a preheating roller component mounted on the rack, a swinging roller component, a cooling roller component, a film unwinding device and a drive device driving the components to rotate, wherein the cooling roller component is mounted on an adjusting mechanism capable of enabling the cooling roller component to move; the swinging roller component and the cooling roller component are matched to compact and bond a plastic woven cloth base body and a film; a molten glue extrusion device is arranged above the space between the swinging roller component and the cooling roller component; and the rack is also provided with a folding roller component for turning over the plastic woven cloth base body coated on a single side. The plastic woven bag film coating compound machine provided by the invention has a novel conception and can turn over the plastic woven cloth base body coated on the single side through a folding structure, then the uncoated surface of the plastic woven cloth base body is coated together with another uncoated plastic woven cloth base body so as to realize double-sided coating of the plastic woven cloth base body, and therefore, the working efficiency is greatly improved, the equipment is reduced, and the cost is lowered..

Description

technical field [0001] The invention relates to the technical field of plastic bag coating equipment, in particular to a plastic woven bag coating compound machine. 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-p...
