AI Technical Summary

Technical Problem

Existing automated sewing equipment struggles to effectively handle three-dimensional sewing and simultaneously control the tension of elastic bands and fabric, resulting in unsatisfactory sewing results. In particular, when dealing with products that require elastic bands, issues such as fabric wrinkling or loss of elasticity can easily occur.

Method used

A fabric feeding and sewing device was designed. By setting up elastic sleeve rollers, fabric support rollers and side pressure rollers, and using a fabric spreading cylinder to drive the elastic and fabric to be the same size after spreading, the device is combined with synchronous belt drive and independent motor control to ensure the tension of the elastic and fabric is integrated, thus achieving efficient sewing.

Benefits of technology

It significantly improves the convenience and dimensional consistency of elastic band and fabric splicing, ensures a smooth and efficient sewing process, improves product quality and fabric capacity, and avoids obstacles to equipment operation.

Abstract

This utility model provides a fabric feeding and sewing device, relating to the field of garment equipment technology. It includes a fabric feeding and spreading device located on one side of the sewing machine head. The fabric feeding and spreading device includes a fabric spreading lateral movement force component, which is connected to and drives a first base to move. An elastic band connecting roller is connected to the first base. A fabric spreading roller and a side pressure roller are respectively arranged on both sides of the elastic band connecting roller. The advantages of this utility model are that the inclusion of the elastic band connecting roller, fabric spreading roller, and side pressure roller ensures the high degree of dimensional consistency between the looped elastic band and the looped fabric after spreading, making sewing smoother and more efficient, effectively improving the fabric's capacity. Because the elastic band and fabric are the same size in the spread state, their tensions can better integrate, providing a solid guarantee for product quality.
