AI Technical Summary

Technical Problem

The existing sewing machine presser foot width is not adjustable, which makes the fabric prone to shifting during the sewing process, resulting in uneven feeding speed and a small force area, affecting the sewing accuracy and uniformity.

Method used

A widened presser foot for sewing machines has been designed, comprising components such as an adjustment groove, an extension rod, a fastening bolt, and a limit wheel. The width of the presser foot can be flexibly adjusted by adjusting the components, and the stability and friction of the fabric are enhanced by the cooperation of the limit wheel and the spring, ensuring smooth feeding.

Benefits of technology

It enables convenient adjustment of presser foot width, improves fabric stability and feeding uniformity, enhances presser foot adaptability and smooth fabric movement, and improves sewing accuracy and operational efficiency.

Abstract

This utility model relates to the field of sewing machine presser foot technology, and discloses a widened feed presser foot for sewing machines. It includes a presser foot body with an adjustment groove inside. A guide foot is fixedly connected to one side of the presser foot body, and an adjustment assembly is provided inside the presser foot body. The adjustment assembly includes an extension rod, which is slidably connected inside the adjustment groove. An extension foot is fixedly connected to one side of the extension rod, and a fastening bolt is threaded inside the extension rod. A butterfly knob is fixedly connected to the top of the fastening bolt. In this utility model, the extension foot is adjusted and limited within the adjustment groove via the extension rod. After the extension foot is adjusted to the correct position, the fastening bolt is simply rotated using the butterfly knob, causing the fastening bolt to screw into the extension rod and abut against the presser foot body. This achieves the effect of easily adjusting the width of the presser foot, solving the problems of narrow presser feet easily causing fabric shifting, uneven feed due to vibration, difficulty in aligning with the fabric, and a small force-bearing area, thus improving the practicality of the presser foot.
