Description
Technical Field
The utility model relates to the technical field of warp knitting machines, in particular to a tension detection mechanism for preventing loops of a warp knitting machine.
Background
The procedure of the warp knitting machine is mainly that yarn raw materials are led out through a yarn feeding mechanism and then enter a loop forming part of the warp knitting machine under the guidance of a yarn guiding mechanism, and the loop forming part of the warp knitting machine is used for knitting grey cloth; the grey cloth knitted by the looping component then enters the traction component, then passes through the cloth guide roller, is redirected by the cloth guide roller and enters the coiling component to be coiled.
The tension of the grey cloth is related to the normal work of each link, for example, if the grey cloth is not tensioned, friction cannot be formed between the pulling component and the grey cloth wound on the pulling component, and the pulling component cannot form pulling action on the grey cloth; the loop forming part cannot normally withdraw loops and form loops, so that loop forming knitting operation is completed; the winding member cannot form a constant tension by the weight rod, and is wound in a state of the constant tension. Therefore, in the working process, the grey cloth always needs to maintain certain tension.
However, the tension of the gray fabric is generated by the pulling of the relevant links, and the normal operation of the relevant links directly affects the tension of the gray fabric. That is, in the warp knitting procedure, the working loops of each relevant link are buckled, one link is abnormal, and after the grey cloth loses tension, the normal work of other links is necessarily affected, so that the whole warp knitting operation is affected. If the coiling device component is abnormal, the fabric loses tension under the working condition that the fabric is not coiled; after the fabric loses tension, the friction coefficient of the fabric of the traction part is further reduced to slip, the fabric cannot normally withdraw loops in the looping part to form loop faults, and finally the knitting needle part is damaged.
In the existing warp knitting machine, the tension of the grey cloth is not monitored in real time, and the running equipment is possibly damaged due to the fact that the grey cloth is not tensioned at any time, so that the failure rate is high.

The warp knitting machine loop-forming tension detection mechanism is characterized in that a loop forming component 1 of a warp knitting machine is used for loop forming yarns, so that the loop forming yarns are woven into grey cloth; the pulling part 2 is used for pulling the formed grey cloth; the cloth guide roller mechanism 3 is used for guiding the grey cloth; the winding device 4 is used for winding the grey cloth to enable the grey cloth to be wound.
When the warp knitting machine loop-forming tension detection mechanism is in operation, the warp knitting machine loop-forming component 1 moves to knit yarns into grey cloth, the grey cloth 10 knitted by the warp knitting machine loop-forming component 1 sequentially enters the traction component 2, the cloth guide roller mechanism 3 and the coiling device 4, and the grey cloth is sequentially wound by the traction component 2, the cloth guide roller mechanism 3 and the coiling device 4. The grey cloth which enters the traction component 2, the cloth guide roller mechanism 3 and the coiling device 4 in sequence enters the cloth guide roller after being tensioned by the traction component 2, and enters the coiling component to be coiled after being reversed by the cloth guide roller.
In the loop-forming prevention tension detection mechanism of the warp knitting machine, in the cloth guide roller mechanism 3, a machine plate 31 is used for bearing a cloth guide roller 32 and installing an induction device 33, a chute 311 is formed on the machine plate 31, the cloth guide roller 32 is positioned in the chute 311, and the chute 311 guides the movement of the cloth guide roller 32 therein; the cloth guide roller 32 is used for guiding the grey cloth 10 so that the grey cloth 10 can be reversed; the sensing device 33 is used for sensing the cloth guide roller 32 positioned in the bottom of the chute 311.

After the cloth guide roller 32 rolls down to the bottom of the chute 311, the sensing device 33 senses the position signal of the cloth guide roller 32. The position of the cloth guide roller 32 can be determined according to the position signal of the cloth guide roller 32 sensed by the sensing device 33, and thus whether the gray fabric 10 has tension can be determined.

In this way, the tension of the fabric 10 may be sequentially converted into the position of the fabric guide roller 32 and the position signal sensed by the sensing device 33, and according to the position signal of the fabric guide roller 32 sensed by the sensing device 33, whether the fabric 10 has tension may be determined, and the tension of the fabric 10 may be monitored in real time. By monitoring the tension of the grey cloth in real time, the device can find out and respond in time when the device is abnormal and the grey cloth is tension-free, for example, the device stops in time, and equipment faults such as the phenomenon that the friction coefficient of the fabric of the traction part is reduced to slip, the fabric cannot normally withdraw from the loop in the loop forming part to form a loop, the damage of the knitting needle part and the like are avoided.
In the loop-forming prevention tension detecting mechanism of the warp knitting machine, the center line of the sliding groove 311 is preferably arranged in an inclined manner. When the center line of the chute 311 is inclined, the cloth guide roller 32 has not only a vertical displacement but also a horizontal displacement when moving along the chute 311.
