Description

Technical Field

[0001] The utility model relates to the field of textile equipment, in particular to a yarn tension self-adapting regulating mechanical device. Background Art

[0002] Yarn spinning is a process of converting fiber materials into yarns and making fabrics through weaving, weaving or knitting. Among them, yarn tension adjustment is one of the key steps in the textile process. During the textile process, the change of yarn diameter on the disc head and the operation of the textile machine often bring about irresistible fluctuations in yarn tension. The stability of yarn tension directly affects the quality and performance of textiles. The purpose of tension adjustment is to keep the yarn tension within a suitable range during the operation of the textile machine to ensure the normal transportation of the yarn and uniform textile effect during the textile process.

[0003] In the prior art, most of the adjustment devices use sensors, control units and drive motors to achieve tension adjustment. The sensor detects the tension of the yarn and converts it into an electrical signal. The control unit then receives the electrical signal and makes judgments and processes it according to the preset tension range. Finally, the control unit issues instructions to control the electric adjustment device to automatically adjust the yarn tension. However, such devices are expensive and difficult to maintain. In the existing mechanical devices, most of them are manually adjusted so that the tension can be maintained within a certain range, but it is difficult to have a good active feedback adjustment for the change of tension.

The initial state of the fourth spring 601 and the fifth spring 602 is a stretched state.

[0058] The working principle of the yarn tension adjustment device is:

[0059] ① Select a preset yarn tension. According to the friction coefficient of the rubber brake block 802 and the preset yarn tension, the appropriate stiffness coefficient of the first spring 904 can be calculated to offset the increase in yarn tension caused by the decrease in yarn radius. According to the applied brake block pressure, select the appropriate second spring 201, third spring 202, and the corresponding pre-stretching amount. Try to select a small stiffness coefficient to make the pre-stretching amount as large as possible. Secondly, select the appropriate fourth spring 601, fifth spring 602, and the appropriate pre-stretching amount so that the third movable rod 401 and the fourth movable rod 402 are in a posture that is as horizontal as possible when the yarn starts to be transported.

[0060] ② During the working process, the yarn is driven by the textile machine, and the winding head 11 starts to rotate, and the yarn tension reaches the preset value. The first tension feedback mechanism 9 works as follows: At this time, the double flat wheel 902 is subjected to the force of the first spring 904 and presses against the yarn of the winding head 11. As the textile machine continuously pulls the yarn, the radius of the yarn on the winding head 11 becomes smaller, and the radius of action of the yarn tension on the winding head 11 decreases. In order to pull the winding head 11, the yarn tension tends to increase. At the same time, the compression of the first spring 904 decreases, and the braking force applied by the first brake block 8-1 and the second brake block 8-2 to the winding head 11 also decreases, thereby offsetting the tendency of the yarn tension to increase and keeping it in a stable range.

[0061] In addition, due to the start and stop of the machine and other factors that occur during the weaving process, the yarn tension may increase or decrease. The second tension feedback mechanism works as follows: when the tension increases, the yarn will pull the third movable rod 401 and the fourth movable rod 402 upward. At this time, the first connecting rod 301 and the second connecting rod 302 will also move upward, and the stretching amount of the second spring 201 and the third spring 202 will decrease. The force applied by the first brake block 8-1 and the second brake block 8-2 to the winding drum head 11 will be correspondingly reduced, making the winding drum head 11 easier to be pulled. Thereby reducing the tension of the yarn and maintaining the tension balance; when the tension decreases, the third movable rod 401 and the fourth movable rod 402 will be pulled downward by the pulling force of the fourth spring 601 and the fifth spring 602. At this time, driven by the first connecting rod 301 and the second connecting rod 302, the stretching amount of the second spring 201 and the third spring 202 increases, and the force applied by the first brake block 8-1 and the second brake block 8-2 to the winding drum head 11 increases, thereby increasing the force required to pull the winding drum head 11, that is, the yarn tension increases, maintaining the tension balance.
