Abstract

The invention discloses a wire drawing machining system for polypropylene plastic woven bag preparation, and relates to the technical field of plastic woven bag preparation. The wire drawing machining system comprises a preparation machining table, a wire extruding device and a wire drawing winding roller, the bottom of the wire extruding device is in threaded connection with the top of the preparation machining table, the wire drawing winding roller is located on the right side of the wire extruding device, and wire drawing transition pipes are arranged on the right side of the wire extruding device. Plastic is subjected to wire drawing through the cooperation of the wire drawing transition pipes and the wire drawing winding roller, the wire drawing winding roller can roll up and store drawn wires during rotation, the plastic drawn wires make contact with arc-shaped expansion rings during rolling-up and storage, under the action of the winding force of the wire drawing winding roller, the plastic drawn wires can apply pressure to the arc-shaped expansion rings along with the winding force, contact of elastic force on the plastic drawn wires on the arc-shaped expansion rings is facilitated, and the phenomenon that the drawn wires are wound when the drawn wire winding roller winds the plastic drawn wires is avoided.

Description

technical field [0001] The invention relates to the technical field of preparing plastic woven bags, in particular to a wire drawing processing system for preparing polypropylene plastic woven bags. Background technique [0002] Polypropylene is a semi-crystalline thermoplastic with high impact resistance, strong mechanical properties, and resistance to various organic solvents and acid and alkali corrosion. It is widely used in the industry and is one of the common polymer materials. 1. Plastic woven bags are divided into polypropylene bags according to the main material composition. The main production process is to use the woven wire formed by extruding and cooling plastic raw materials, and weave the product, which is generally called woven bag. There are technical problems with: [0003] 1. At present, when drawing plastic woven bags, it is generally necessary to roll up and store the formed drawing, but when rewinding the formed drawing, due to the action of the windi...
