Warp knitting machine is very popular in the textile industry, its automatic operation, a lot of convenience, but in the actual operation, there are often some problems, such as the appearance of horizontal lines, affecting the final quality, we must find out the reasons, and be reasonable to solve.
Warp knitting machine stripe:
One is the warp knitting running bar, that is, during the operation of the warp knitting machine, the cloth appears intermittently on the bar, which seriously affects the fabric quality. Most of the reasons for the formation of this running bar is that the let-off system is not working normally, which often occurs in negative or semi-active let-off. In the use of fixed length positive let-off after great improvement, but the let-off system is not working normally, it often occurs, the important thing is that the let-off box worm and worm gear mesh is poor.
The other is the warp knitting stop line, that is, the warp knitting stop bar problem, that is, when the warp knitting machine starts again after stopping, there is a cross bar on the cloth surface. The main problem is that during the process of the machine from full speed to brake stop, the change law of the spindle speed of the machine and the change law of the let-off device slowing down and stopping the let-off are not synchronized and inconsistent, and the same is true when the machine starts. In the process of the spindle from static to full speed operation, it is difficult for the let-off system to synchronize the whole process and cause the horizontal bar, which is a world problem. In general, a good way to solve the problem is to reduce the number of stops, so the warp braid worker can have meals next to the machine without turning off the car.
In order to ensure the final quality, in the process of boot, should be the front machine logistics inspection of the warp knitting machine accessories is safe, do three times before the machine, after the machine to go once before the machine carefully check the front and back of the cloth, whether there is broken yarn, edge holes loose, yarn thickness, yarn half, jump yarn, wool yarn, pan head yarn loss.
