Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of textiles, in particular to a pulling mechanism for super-elastic knitted fabrics. Background Art
[0002] With the development of the production industry and the improvement of people's living standards, people have higher and higher requirements for knitted fabrics. High-quality knitted fabrics can be used to weave high-end textiles to meet people's needs. Knitted fabrics are fabrics formed by bending yarns into loops and interlacing them with knitting needles. Knitted fabrics need to be pulled in the early stage. 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 air permeability, and it is soft and comfortable to wear, and has good warmth retention. The knitted fabric pulling device currently on the market has a low pulling effect on the knitted fabric, and cannot make the knitted fabric get a good pulling effect. Some super-elastic knitted fabrics have high elasticity. When pulling, it is easy to cause the knitted fabric itself to be pulled inadequately due to its own high elasticity, which affects the quality. In view of this, the inventor proposes a pulling mechanism for super-elastic knitted fabrics. By setting a close roller and a roller shaft with tensioning force, the super-elastic knitted fabric can be better pulled, thereby improving the quality of the super-elastic knitted fabric.
[0003] In order to improve the pulling effect of knitted fabrics, a Chinese patent (authorization announcement number: CN215856625U) discloses a knitted fabric pulling device. The utility model includes a transmission mechanism and a pulling mechanism, wherein the pulling mechanism is composed of a pulling shell, a connecting rod, a cloth pressing roller, a pulling roller and a rotating shaft. The pulling mechanism is on the right side of the transmission mechanism. A first support column and a second support column are provided above the outer wall of the pulling shell, and there are two first support columns and two second support columns. A connecting rod is provided between the two first support columns, and a cloth pressing roller is provided between the two second support columns. A pulling roller and a rotating shaft are fixedly installed inside the pulling shell. The utility model solves the problems of low pulling effect of knitted fabrics through the cloth pressing roller and the pulling roller.
[0004] This solution still has some shortcomings in application. Since knitted fabrics have a certain elasticity, some knitted fabrics have high elasticity and are elastic enough, they often need to be pulled longer than ordinary knitted fabrics to ensure the pulling quality. At the same time, some knitted fabrics are light in weight and may be at risk of breaking when pulled in a whole circle, so they need to be effectively protected. Therefore, it is necessary to improve the structure of the super-elastic knitted fabric pulling device so that it can perform better pulling, ensure the pulling speed and quality, and improve the practicability of the device.
