Elastic cloth fixed-length cutting method

Abstract

The invention relates to an elastic cloth fixed-length cutting method. According to the elastic cloth fixed-length cutting method, an automatic cutting device is adopted, wherein the automatic cuttingdevice comprises a bottom plate, a mounting frame, a material placing mechanism and a cutting mechanism; a specific method when the automatic cutting device performs fixed-length cutting on the elastic cloth comprises the steps of carrying out winding, device adjustment, feeding, fixed-length cutting, blanking and collecting. The mounting frame is mounted at the upper end of the bottom plate; thematerial placing mechanism and the cutting mechanism are mounted on the side wall of the mounting frame; the material placing mechanism is located in the middle of the cutting mechanism; and the cutting mechanism comprises a first rotating roller, a second rotating roller, a conveying belt, a vacuum suction cup, a driving branched chain, a rotating cam and a lifting cutter plate. The elastic cloth is cut into the cloth blocks with the same length through the cooperation of the material placing mechanism and the cutting mechanism, the elastic cloth can be pressed and limited in the cutting process, the stretching deformation is prevented, the distance of each movement of the elastic cloth can be changed according to the actual situation, and then the length of the fixed length cutting is changed.

Description

technical field [0001] The invention relates to the field of textile fabrics, in particular to a fixed-length cutting method for elastic fabrics. Background technique [0002] Elastic fabrics are fabrics with a certain stretching elasticity, including spandex fabrics, nylon fabrics, etc. Because of their excellent elasticity, they are also called elastic fibers. They have been widely used in clothing fabrics and have the characteristics of high elasticity. The main application lies in the manufacture of tights, sportswear, bodyguards and shoe soles, etc. According to the needs of the application, its varieties can be divided into warp stretch fabrics, weft stretch fabrics and warp and weft two-way stretch fabrics. [0003] Before the elastic fabric is put into use, it often needs to be cut to an appropriate size. However, there are some difficulties in the process of cutting the elastic fabric to length. If it is too large, the overall length of the elastic fabric will chan...

Problems solved by technology

[0003] Before the elastic fabric is put into use, it is often necessary to cut it to an appropriate size. However, there are some difficulties in the process of cutting the elastic fabric to length. If it is too large, the overall length of the elastic fabric will change, and if the positioning force is small, the elastic fabric will slide due to the pull of the cutting tool when cutting it, resulting in the inability to accurately measure the cutting length, and it is difficult to guarantee the length of each cut The consistency of the product affects the factory quality of the product
