Overedging mechanism of bag sewing machine

Abstract

The invention discloses an overedging mechanism of a bag sewing machine, which comprises a fixing plate and a hemming cylinder, wherein the hemming cylinder is fixedly connected with the fixing plate which is installed on the bag sewing machine; overedging materials are inputted from the front end of the hemming cylinder and outputted from the back end of the hemming cylinder after penetrating through the hemming cylinder; the hemming cylinder is formed by the enclosure of an upper guiding plate and a lower guiding plate; the upper guiding plate is gradually closed up; both sides on the back end of the upper guiding plate are respectively folded and extended inwards to form a first hemming part; the lower guiding plate is positioned at the lower part of the upper guiding plate; both side edges of the lower guiding plate are fixedly connected with both side edges of the front end of the upper guiding plate respectively; a tongue piece is formed on the tail end of the lower guiding plate and is positioned above the first hemming part of the upper guiding plate; and a first channel for the overedging materials to pass is formed between the upper guiding plate and the lower guiding plate. The overedging mechanism also comprises two hollow drums. The two drums, parallel to each other along the conveying direction of the overedging materials, are fixed at the bottom of the lower guiding plate. The rear ends of the two drums are suspended in the first channel. The overedging mechanism also comprises a separating pin. One end of the separating pin is fixed to the top of the upper guiding plate, while the other end of the separating pin, protruding out of the upper guiding plate, is bent downwards along the conveying direction of the overedging materials. The separating pin is positioned at the center between the two drums.

Description

technical field [0001] The invention relates to a luggage sewing machine, in particular to a luggage sewing machine with a hemming mechanism. Background technique [0002] A sewing machine is a machine that uses one or more sewing threads to form one or more stitches on the sewing material to interweave or sew one or more layers of sewing material.

Problems solved by technology

With the high-speed development of traffic and the increasing number of people traveling, all kinds of bags have become a tool for carrying personal items such as personal belongings and clothes, and various sewing machines for sewing bags have also emerged as the times require With the continuous improvement of people's living and consumption levels, higher requirements are put forward for the appearance, structure, performance and delicacy of bags, and higher requirements are also put forward for the bag sewing machines for sewing bags. The existing common Bags are usually sewn with hemming strips at the corners around them, which can protect the edges of the bags from being damaged. However, the existing sewing machines for bags do not have relative guiding mechanisms. Alignment sewing, on the one hand, has low work efficiency, and on the other hand, has large errors, and it is difficult for the sewn bags to meet the requirements of beauty and refinement. Realize the sewing combination of edging material and luggage, improve the aesthetics and delicacy of luggage sewing, and improve production efficiency
