Description

A Warp Knitting Machine Convenient for Tension Control

technical field

The invention relates to a textile machine, in particular to a warp knitting machine which is convenient for tension control.

Background technique

The existing warp knitting machine yarn tension compensation device is relatively traditional, because the jacquard comb plays a jacquard effect in weaving, so the warp let-off amount of the yarn is different, so the warp let-off is adopted on the creel, so the tension of each yarn is all different.

As shown in Figure 1, the traditional tension device is mainly composed of fan-shaped sprocket 1-7, return spring 1-5, fixed bolt 1-1 fixed on the left and right wall panels, a rotatable tension rod installed on the machine, and a fixed installation The tension sheet 1-9 on the tension rod constitutes; wherein, the sector sprocket 1-7 and the return spring 1-5 are connected by a chain 1-6, and the other end of the return spring 1-5 passes through the hook 1-3, The clamping block 1-2 and the fixing bolt 1-1 are fixed on the wallboard, and the compensation device makes the tension plate 1-9 reciprocate through the elastic force of the return spring 1-5, so as to achieve stable tension of the yarn. When the warp knitting machine is working, every time the main shaft rotates a circle, the loop forming mechanism performs a reciprocating motion. When forming a loop, the tension of the yarn drives the tension sheet 1-9 when the knitting needle pads and presses the yarn each time, and The return spring 1-5 is driven by the sector sprocket 1-7, and the pulling force of the return spring 1-5 is used to ensure that the tension plate 1-9 swings up and down once, so as to compensate the yarn tension. When the existing warp knitting machine is working, the yarn is woven from the creel through the yarn passing rod, the yarn guide rod, the tension sheet 1-9, and then knitting, and the yarn tension is compensated by the above method, so as to ensure the knitting motion However, the yarn has the following disadvantages when weaving with this tension compensation device. Since the knitting is only done in reciprocating motion during weaving, the corresponding tension on the yarn is the stage of lapping and pressing. This device can be used to complete the tension control of the yarn. The tension compensation required by the yarn during the knitting motion is not only at these two times, but also needs to be compensated in time when the yarn is moving and knitting. The tension on the knitting needle is relatively large when it is formed into a loop, and when the knitting needle is about to come out of the loop when it is swinging to the final position, the yarn tension cannot be compensated in time, resulting in excessive yarn tension on the knitting needle and deformation, which often leads to machine failure. Missing needle phenomenon occurs, which affects the working speed of the machine.

At the same time, the existing tension compensation device can only control all other yarns through the over-tight yarn, and cannot control the tension of each yarn, let alone guarantee the uniformity of the tension of each yarn, so that the production The distance between the warp lines of the cloth surface is not uniform, which affects the smoothness of the cloth surface.
