Automatic lip inserter for buttonholes

Abstract

The invention relates to an automatic lip inserter for buttonholes, which is capable of effectively improving operating efficiency. The technical scheme includes that the automatic lip inserter for buttonholes is characterized by comprising a presser foot and a hemmer, wherein the presser foot is fixed to the lower end of a presser foot rod of a two-needle sewing machine, and the hemmer is fixed to a warping portion at the front end of the presser foot. The hemmer is upwardly inclined, a cloth strip inlet is arranged at the upper end of the hemmer, and a lip outlet is arranged at the lower end of the hemmer. The hemmer is gradually narrowed from the cloth strip inlet to the lip outlet, and each of the left edge and the right edge of the hemmer is gradually turned to the center line of thehemmer from the rear end to the front end to form a passage for cloth strip hemming. A pressure bolt is fixed between the two turned edges of the hemmer, and a gap which is beneficial to passing of cloth strips is reserved between the pressure bolt and a bottom plate of the hemmer. A shaping pressure orifice is arranged on the lip outlet at the lower end of the hemmer, two sides of the shaping pressure orifice are bent towards the center line of the hemmer to form a cloth strip passage, and the pressure bolt extends out from the lower end of the shaping pressure orifice.

Description

technical field [0001] The invention relates to an auxiliary tool for garment production, in particular to an auxiliary tool for making button doors in garment production, in particular to an automatic molding device for button doors. Background technique [0002] In the clothing production process, the inlaid button door (button door is also called buttonhole) is usually made by hand and template. There are generally 5 processes in hand-made: ironing the molding, 1 step of installing the molding, 2 steps of installing the molding, cutting buttonholes, and sealing the head. Skilled operators generally take about 70 seconds, of which ironing the molding and installing The embedding takes about 35 seconds, and the difference in the operator's proficiency and operating gestures will cause poor quality problems in mass production. Formwork production generally requires 7 processes: ironing the molding, placing garment pieces, placing the molding, turning the molding, removing t...

Problems solved by technology

There are generally 5 processes in hand-made: ironing the molding, 1 step of installing the molding, 2 steps of installing the molding, cutting buttonholes, and sealing the head. Skilled operators generally take about 70 seconds. The embedding takes about 35 seconds, and the difference in the operator's proficiency and operating gestures will cause poor quality problems in mass production

Template making generally requires 7 processes: ironing the moldings, placing the garment pieces, placing the moldings, turning the moldings, removing the moldings, cutting buttonholes, and sealing the head. It usually takes about 85 seconds for skilled operators to complete the operation , in which the four steps of ironing the strips, laying the garment pieces, placing the strips, and turning the strips take about 40 seconds. The quality of the product is relatively stable, but the production process takes a long time
