Material supporting device of flat seaming machine

Abstract

The invention provides a material supporting device of a flat seaming machine, belonging to the technical field of a sewing machine. The technical problems that when an existing flat seaming machine is used for sewing dress materials different in size and elasticity, the sewing is inconvenient and the like, because elastic fabric with elastic shrinkage can be sewn with the dress materials with small elasticity by being supported by external force can be solved. The material supporting device of the flat seaming machine comprises a cylindrical sewing platform arranged on a machine head, a plurality of support pillars parallel to the sewing platform are arranged on the machine head along the circumferential direction of the sewing platform, one of the support pillars is connected with a driving device for driving the support pillar to move along the radial direction of the sewing platform by a link mechanism. The material supporting device of the flat seaming machine has the advantages that the degree of automation is high, the use is convenient and the like.

Description

technical field [0001] The invention belongs to the technical field of sewing machines, and relates to a material supporting device of an interlock sewing machine. 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. Interlock sewing machine is a kind of sewing machine. The stitches it sew are chain sewing stitches. Interlock sewing machines are widely used to sew knitted underwear, sportswear, T-shirts, underwear, waist skirt elastic bands, etc. Elastic fabric neckline, cuffs, etc. Some knitted fabrics weave the elastic band into the material, which is extremely elastic and in a state of elastic contraction in the free state, which brings a lot of inconvenience to the sewing work. If two different sizes and different elastic materials are stitched together, it is necessary to External force stretches the elastically co...

AI Technical Summary

Problems solved by technology

Such a sewing method tends to have many deficiencies, such as the difficulty in controlling the pulling force, and the different sewing skills of different operators, which can easily lead to uneven sewing quality, resulting in large product quality deviations, low yields, and poor quality. The inspection work has brought a lot of trouble; in addition, due to the laborious pulling and increased workload, the long-term work will definitely cause the operator's hands to be sore, which greatly reduces the production efficiency and also affects the quality of the product due to the fatigue of the operator. make an impact

At the same time, the existing stretch sewing machine sewing method also has the disadvantages of low automation and inconvenient operation.
