Abstract

The invention belongs to the field of plastic woven bag production equipment, in particular to an extrusion device for plastic woven bag production. The existing feed pipe feeding speed cannot be automatically adjusted and clogging easily occurs in the existing extrusion device for plastic woven bag production. Now, the following solution is proposed, which includes a thermal insulation cylinder, an extrusion cylinder is arranged on the inner side wall of the thermal insulation cylinder, and a reduction gear box is fixedly connected to one end of the extrusion cylinder, and the reduction gear box is far away from the extrusion material. One end of the barrel is provided with a first drive motor, the invention can automatically adjust the feeding speed in the feeding pipe and the feeding speed of the feeding hopper, so as to prevent the excessive feeding of the extruding barrel and the excessive internal pressure, so as to prevent the extrusion The material barrel is protected, and the agitating shaft can be used to avoid the feeding blockage in the feeding pipe, and when the feeding pipe is accidentally blocked, the feeding pipe can be dredged by the stirring shaft.

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 ...
