Auxiliary limiting device for sewing machine hemming based on magnetic adsorption

Abstract

The invention provides an auxiliary limiting device for sewing machine hemming based on magnetic adsorption, and relates to the technical field of sewing machine hemming. The auxiliary limiting devicefor sewing machine hemming based on magnetic adsorption comprises a bottom plate, wherein an installation plate is fixedly connected to the top of the bottom plate, a needle port is formed in the center of the installation plate, pushing plates are slidably connected to the left and right sides of the needle port in the installation plate, a cover plate is slidably connected to the position, on the left side of the installation plate, of the top of the bottom plate, and a sliding block is slidably connected to the right side of the installation plate in the bottom plate. According to the auxiliary limiting device for sewing machine hemming based on the magnetic adsorption, the wrapping of the cloth edge by a sealing strip can be achieved through a limiting device without manual bending and wrapping, the sewing efficiency is improved, the puling effect on the bending part of the sealing strip can be maintained in the moving process of the sealing strip, so that distribution of the sealing strip on the upper and lower sides of the cloth is more uniform after bending, so as to improve the hemming effect is improved.

Description

technical field [0001] The invention relates to the technical field of sewing machine hemming, in particular to an auxiliary limiting device for sewing machine hemming based on magnetic adsorption. 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 materials. The sewing machine can sew cotton, hemp, silk, wool , artificial fiber and other fabrics and leather, plastic, paper and other products, the stitches are neat and beautiful, flat and firm, with fast sewing speed and easy use. [0003] The sewing machine is also often used for hemming, which is to wrap and sew the seal around the edge of the fabric after bending, so as to protect the edge of the fabric, which is more beautiful and improves the service life of the fabric, but the traditional sewing machine In the hemming process, the manual folding seal is used for sewing.

Problems solved by technology

[0003] The sewing machine is also often used for hemming, which is to wrap and sew the seal around the edge of the fabric after bending, so as to protect the edge of the fabric, which is more beautiful and improves the service life of the fabric, but the traditional sewing machine In the hemming process, the manual folding seal is used for sewing. After sewing for a certain distance, it is necessary to stop and refold. The sewing efficiency is low. In the process of manual folding, uneven folding is easy to occur. And the bending part of the seal is not stretched, so it is prone to uneven distribution of the seal on the upper and lower sides of the fabric, which reduces the effect of hemming
