Drafting and setting device for polyester knitted fabric

Abstract

The invention discloses a drafting and setting device for a polyester knitted fabric, and belongs to the field of fabric production and processing mechanical equipment. A fabric feeding guide roller and a fabric discharging guide roller are sequentially, horizontally and rotationally connected to a fabric processing support; a fabric reciprocating rotating plate is arranged on the fabric processing support between the fabric feeding guide roller and the fabric discharging guide roller; a fabric drafting gear is coaxially, vertically and fixedly arranged in the middle of the fabric reciprocating rotating plate along the side of the fabric processing support; a fabric drafting toothed plate at the output end of a fabric drafting air cylinder is in meshed connection with the fabric drafting gear coaxially fixed to the middle of the fabric reciprocating rotating plate; reciprocating drafting rotating rollers are symmetrically arranged on the two sides of the fabric reciprocating rotating plate; and the output end of a fabric pulling and conveying motor is in transmission connection with a fabric pulling and conveying guide roller through a fabric pulling and conveying belt. The device is reasonable in structural design, can efficiently and stably perform sectional drafting and setting processing in the knitted fabric conveying process, improves the production and processing automation degree of the knitted fabric, and meets the processing and using requirements.

Description

technical field [0001] The invention belongs to the field of fabric production and processing machinery, in particular to a drafting and setting device for polyester knitted fabrics. Background technique [0002] Knitted fabrics refer to fabrics formed by bending yarns into loops with knitting needles and interlocking them. The difference between knitted fabrics and woven fabrics lies in the shape of the yarns in the fabric. Knitted fabrics are widely used in clothing fabrics, linings, home textiles and other products, and are loved by consumers. Knitted fabrics have good elasticity, moisture absorption, breathability, comfort and warmth, and are the most widely used fabrics for clothing. The raw materials of knitted fabrics are mainly It is a natural fiber such as cotton, linen, silk and wool, as well as chemical fibers such as nylon, acrylic and polyester. Knitted fabrics have rich texture changes, various varieties, and unique appearance. In the past, they were mostly use...

Problems solved by technology

During the production and processing of existing knitted fabrics, it is difficult to achieve continuous and stable drafting and setting during the transmission process of knitted fabrics, and the existing knitted fabrics drafting equipment has complex structure and troublesome operation, and it is difficult to realize the drafting and setting of knitted fabrics The efficiency of processing, in the process of drafting knitted fabrics, the fabrics cannot be processed smoothly and orderly in sections during the continuous transmission process, it is difficult to achieve accurate and effective drafting processing of knitted fabrics, and it is easy to cause knitted fabrics to be drafted. Insufficient stretching or excessive drafting, it is difficult to ensure the production and processing quality of knitted fabrics, and cannot meet the needs of large-scale continuous production of knitted fabrics
