Description

Technical Field

[0001] The utility model relates to the technical field of knitted fabrics, in particular to a knitted fabric pulling mechanism. Background Art

[0002] Knitted fabrics are made by bending yarns into loops and interlacing them with knitting needles. The difference between knitted fabrics and woven fabrics is the different forms of yarns in the fabrics. Knitting is divided into weft knitting and warp knitting. Knitted fabrics are widely used in clothing fabrics, linings, home textiles and other products, and are loved by consumers.

[0003] In the production process of knitted fabrics, a pulling mechanism is needed. After searching, the Chinese patent CN215856625U in the prior art discloses a knitted fabric pulling device. In the early stage of the knitted fabric, the knitted fabric needs to be pulled. Pulling the fabric can make the knitted fabric evenly stressed. Before the knitted fabric is pulled, the knitted fabric fibers are tight. After pulling, the knitted fabric will have good moisture absorption and breathability, and it is soft and comfortable to wear, and has good warmth retention. The knitted fabric pulling device on the market currently has a low pulling effect on the knitted fabric, and cannot make the knitted fabric get a good pulling effect. The utility model provides a knitted fabric pulling device composed of a transmission mechanism and a pulling mechanism, wherein the transmission mechanism is composed of a transmission housing, a cylinder, a moving plate and a motor, and the pulling mechanism is composed of a pulling housing, a first support column, a bearing, a second support column, a connecting rod, a cloth pressing roller, a knitted fabric, a pulling roller, a rotating shaft and a storage port. The cloth pressing roller and the pulling roller solve the problem of low knitted fabric pulling effect.

[0004] However, during the use of the utility model, since the position of the pulling roller is fixed, when the staff places the knitted fabric on its surface, the knitted fabric needs to be stretched in advance. At the same time, the knitted fabric is always in a transmission state. If it is not repeatedly stretched, the pulling effect may be affected and the production needs cannot be met. Therefore, a knitted fabric pulling mechanism is proposed to solve the above-mentioned problems. Utility Model Content
