Description

Technical Field

[0001] This utility model relates to the field of woven bag processing technology, and in particular to an automatic woven bag cutting device. Background Technology

[0002] The woven bag processing technology field centers on plastic processing, encompassing the entire process from the modification and blending of polypropylene and polyethylene raw materials, flat yarn stretching and molding, to the weaving, printing, cutting, and sewing of circular woven fabric. It involves the interdisciplinary application of mechanical design, automation control, heat treatment, and materials mechanics. This field continuously optimizes drawing process parameters, improves weaving density control technology, and combines automated cutting and sewing equipment to drive the development of woven bags towards high strength, lightweight, and functionalization. Widely used in agricultural, industrial, and logistics packaging, automated woven bag cutting equipment is a key component in the field's automation upgrade. By integrating high-precision mechanical design, intelligent sensor control, and high-speed cutting technology, it achieves precise positioning, efficient cutting, and waste recycling of the woven fabric, significantly improving production efficiency and product quality stability.

[0003] When woven bag production requires high-efficiency, high-precision, and large-scale continuous cutting operations, automatic woven bag cutting equipment is needed to meet the demands of cost reduction, efficiency improvement, and quality stability. Automatic cutting equipment is an automated production device that integrates mechanical transmission, intelligent control, and precision detection technology. It uses a servo motor to drive the feeding mechanism to achieve precise conveying of woven bag rolls, and photoelectric sensors to locate the cutting position in real time. It uses high-speed rotating blades to complete automated cutting, effectively replacing traditional manual cutting methods, significantly improving production efficiency, reducing error rates, and ensuring operational safety. Most existing cutting equipment uses fixed-connection blades for cutting, which leads to increased replacement costs, reduced work efficiency, and reduced practicality. Utility Model Content
