technical field

The utility model belongs to the technical field of warp knitting machines, in particular to a double pulling mechanism of a winding device of a warp knitting machine.

Background technique

In order to make the production of the warp knitting machine can be carried out continuously and smoothly, the braided fabric that the warp knitting machine is woven must leave the loop forming area immediately. The function of the pulling mechanism is to pull the formed gray cloth from the loop forming area and transfer it to the take-up mechanism. The take-up mechanism winds the drawn gray cloth into a cloth roll through a certain tension. In the process of fabric transmission from the pulling mechanism to the crimping mechanism, it is necessary to ensure that the given pulling force is uniform, stable and sustainable, and the process of rolling the fabric must ensure that the fabric is in a certain state of tension.

The distance from the pulling mechanism to the crimping mechanism is relative to the fabric, which is a flexible material. Although the fabric is in a tensioned state, it still fluctuates during the transmission process, and the current pulling mechanism cannot reduce it well. Minimizing or eliminating the stirring of the fabric will cause the tension of the fabric to fluctuate during the transmission process, which will have a certain impact on the quality of the fabric.
