Abstract

The invention belongs to the field of plastic woven bag production equipment, and particularly relates to an extrusion device for producing plastic woven bags. As an existing extrusion device for producing plastic woven bags has the problems that the feeding speed in a feeding pipe cannot be automatically adjusted and blockage is prone to being caused, the following scheme is provided. The extrusion device comprises a heat insulating cylinder, the inner side wall of the heat insulating cylinder is provided with an extrusion cylinder, one end of the extrusion cylinder is fixedly connected with a reduction gear box, the end, far away from the extrusion cylinder, of the reduction gear box is provided with a first driving motor. By means of the extrusion device, the speed of feeding in the feeding pipe and the speed of discharging of a feeding hopper can be automatically adjusted, the condition of the excessive internal pressure caused by too much feeding of the extrusion cylinder is prevented, the extrusion cylinder is protected, the feeding blockage condition inside the feeding pipe can be avoided with the help of a stirring shaft, and the feeding pipe can be dredged by means of the stirring shaft when the feeding blockage conditions are accidently caused in the feeding pipe.

Description

technical field [0001] The invention relates to the technical field of plastic woven bag production equipment, in particular to an extrusion device for plastic woven bag production. Background technique [0002] According to the main material composition, plastic woven bags are divided into polypropylene bags and polyethylene bags; according to the sewing method, they are divided into seamed bottom bags and seamed bottom bags; currently they are widely used in the packaging of fertilizers, chemical products and other items. Its main production process is to use plastic raw materials to mix, extrude film, cut, unidirectional stretch into flat yarn, and finally weave through warp and weft. [0003] The extrusion stage in the production process of the existing plastic woven bags is usually carried out by means of an extrusion device. The plastic granule raw material is poured into the extrusion barrel through the feed pipe, and then the plastic granules in the extrusion barrel ...
