Description

A tensioning device for textile equipment

technical field

The utility model relates to the technical field of textile machinery, in particular to a tensioning device used on textile equipment.

Background technique

In the textile industry, looms weave yarns into fabrics, and most of the warp yarns of the fabric are wound on the warp beams in advance, and the warp beams provide the warp yarns. The weft of the fabric is provided by the yarn drum. In the process of spinning the yarn into a fabric, in order to make the fabric even and flat, the yarn needs to be tightened during the yarn spinning process, and the yarn tension is to increase the tension of the yarn itself. Usually, the method of increasing the yarn tension is to reduce the speed of yarn unwinding. However, in this method, the tension of the yarn is uneven, the speed of yarn unloading is difficult to control, and the quality of the fabric is unstable.

The patent with the first application number of 201510412326.X discloses a yarn tensioning device for textiles, which includes a base, a yarn guide rod fixing column, a yarn guide rod, a yarn tensioning rod fixing column, a yarn tensioning rod movable groove, The yarn positioning ring and the yarn tension rod, the yarn guide rod fixed column and the yarn tension rod fixed column are fixed on the base, the yarn guide rod is fixed horizontally between the yarn guide rod fixed columns, and the yarn tension rod is fixed A yarn tension rod movable groove is arranged in the column, the yarn tension rod can move vertically up and down in the yarn tension rod movable groove, and a plurality of yarn positioning rings are arranged on the yarn tension rod. The thread tensioning device has the advantages of simple structure and convenient use, and can ensure the stable tension of the yarn, reduce the production cost of the fabric, and improve the quality of the fabric.

However, when this device is working, since the yarn guide rod is in a fixed state, the yarn will always rub against the yarn guide rod when it is guided. After a long time of friction, the temperature of the yarn guide rod will rise, which will damage the yarn structure. Also because the yarn guide rod is always rubbing against the yarn, the yarn will also be worn, and there is no structure to separate the yarn on the wire rod. When the yarn passes through the yarn guide rod, knots will also occur. On the other hand, this device has only one yarn tensioner, which cannot meet the requirement of processing quantity when there are many yarns to be processed. Therefore, there is an urgent need in the market for a yarn with less friction, no knots, and more yarns to be processed. tensioning device.

The user can choose different numbers of yarn tensioning rods according to the situation, and then fix them on the sliding plate. Up to 5 yarn tensioning rods can be fixed on the board. When the user needs to adjust the height of the yarn tensioning rods, they only need to adjust the height of the sliding board, which can achieve a larger number of yarns processed by the tensioning device. Purpose.

The utility model is further configured as follows: a plurality of heat dissipation holes are arranged at the bottom of the limiting groove, the heat dissipation holes are arranged in a circle along the bottom of the limiting groove, and the heat dissipation holes pass through the fixing column of the yarn guide rod at the same time.

When the yarn guide wheel rotates in the limit slot, heat will be generated due to contact with the limit slot, thereby destroying the structure of the yarn guide wheel and reducing its service life. By adopting the above technical scheme, several edge limiters are arranged at the bottom of the slot. The heat dissipation holes are arranged in a circle at the bottom of the groove, and the heat dissipation holes pass through the fixed column of the yarn guide rod. Therefore, when the user is using this product, the yarn guide wheel will rub against the limit groove due to the rotation, and the heat will pass through the limit groove. The heat dissipation holes at the bottom of the groove are transmitted out, which reduces the risk of the yarn guide wheel structure being damaged due to excessive temperature, and because the heat dissipation holes are set at the bottom of the limit groove, the rotation of the yarn guide wheel is not affected, and the purpose of heat dissipation is achieved. .

The utility model is further provided that: both ends of the yarn guide wheel are arc-shaped, and the cross-section of the limiting groove is arc-shaped.

By adopting the above technical solution, the end faces at both ends of the yarn guide wheel are set in an arc shape, the cross section of the limit groove is set in an arc shape, the end faces at both ends of the yarn guide wheel are matched with the limit groove, and the arc structure is relatively frictional The force is smaller, and the smooth coefficient between the surfaces is higher, so that the friction force between the two ends of the yarn guide wheel in contact with the limit groove is smaller.

The yarn guide wheel 9 is provided with a number of yarn guide grooves 10. Both ends of the yarn guide wheel 9 are inserted into the limit grooves 8. Inside.

The number of 4 yarn tensioning rods is 1 to 5. Both ends of the yarn tensioning rod 4 are provided with sliding plates 11. The sliding plates 11 are slidably connected with the sliding grooves 7, and there are 5 screw holes 12 on the sliding plate 11. , the yarn tensioning rod 4 is fixed with the sliding plate 11 through screw connection.

The bottom of the limiting slot 8 is provided with a number of heat dissipation holes 13 , and the heat dissipation holes 13 are arranged in a circle along the bottom of the limiting groove 8 , and the heat dissipation holes 13 pass through the yarn guide rod fixing column 3 at the same time.

Both ends of the yarn guide wheel 9 are arc-shaped, and the cross-section of the limiting groove 8 is arc-shaped.

Working principle: On the basis of the original structure, a yarn guide wheel 9 for guiding the yarn is set on the yarn guide rod 2. Since the yarn guide wheel 9 is not fixed, the yarn guide wheel 9 will move when the yarn is moving. With the rotation, the friction between the yarn and the yarn guide wheel 9 is reduced, so the yarn wear rate will be reduced, and the heat generation of this part will also be reduced. The yarn guide wheel 9 is provided with a number of yarn guide grooves 10. When processing the yarn, each yarn can be placed in a different yarn guide groove 10, so the yarn will not be knotted here, and a limit groove 8 is set on the yarn guide rod fixing column 3, Insert the yarn guide wheel 9 into the limiting groove 8 twice. The limiting slot 8 limits the left and right movement of the yarn guide wheel 9 without restricting the yarn guide wheel 9 to rotate, making the yarn guide wheel 9 more stable.
