Single-shuttle multi-needle overlocking apparatus

Abstract

The invention provides a single-shuttle multi-needle overlocking apparatus, comprising a nose. A fixed block in circular shape is fixedly fitted to the lower portion of the nose, more than two vertically slidable sewing needles are fitted to the circular edge of the fixed block, a cam circular in shape is fitted to the upper portion of the fixed block and is fitted coaxially to a fitting block; the lower portion of the nose is provided with a horizontal sewing table, a needle plate is fitted on the sewing table, and the cam abuts and pushes the sewing needles during rotating to pass sequentially through the needle plate; the lower portion of the needle plate is provided with a horizontally fitted rotary shuttle coaxial to the fixed block, a thread hooking tooth of the rotary shuttle can sequentially hook sewing threads passed through a needle hole when rotating with the rotary shuttle. The single-shuttle multi-needle overlocking apparatus enables simpler transmission structure of an overlock machine and greatly reduced processing and assembly difficulty of the overlock machine, and manufacture cost and maintenance cost of the overlock machine can be decreased greatly.

Description

Technical field [0001] The invention belongs to the technical field of garment processing machinery, in particular to a sewing edge banding device with one shuttle and multiple needles. Background technique [0002] In the process of clothing processing, fabrics need to be selected first, then the fabrics are cut and processed, and the cut fabrics are sewn. According to the material of different clothes, the fabric needs to be processed differently, such as wrinkle removal, wrinkling, sanding, edge banding and so on. During garment processing, it is often necessary to perform edge sealing on the edge of the cloth cutting to prevent the cloth from opening during the processing. In the current garment processing, overlock sewing machines are usually used to process the edge of the fabric. There is an open thread on the trimmed edge. The overlock sewing machine can be used not only for hemming, but also for sewing T-shirts, sportswear, underwear, knitting and other fabrics. ...

AI Technical Summary

Problems solved by technology

In the traditional overlock sewing machine, each thread corresponds to a needle, and each needle corresponds to a rotary hook. In this way, each needle needs to correspond to a complete sewing system, which makes the transmission structure of the entire overlock sewing machine more complicated and easy to break. material failure, and the equipment cannot be completed during assembly and maintenance
