Description

Technical Field

[0001] The utility model belongs to the technical field of air layer fabric production, in particular to a warp knitting tension compensation device for air layer fabric. Background Art

[0002] In the field of textile industry, air layer fabrics have become indispensable materials for many industries such as clothing and household goods due to their excellent warmth retention, breathability and comfort. However, in the warp knitting production process of air layer fabrics, precise control of yarn tension is one of the key factors to ensure fabric quality. Unstable tension will not only cause appearance defects such as wrinkles and unevenness of the fabric, but may also affect the physical properties of the fabric, such as tensile strength and wear resistance, thereby reducing the overall quality and market competitiveness of the product.

[0003] At present, the tension compensation devices widely used in the market mostly adopt hydraulic adjustment methods. This type of device adjusts the tension of the yarn through the pressure change of the hydraulic system. Although it realizes the adjustability of the tension to a certain extent, its shortcomings are also obvious. First, the response speed of the hydraulic system is relatively slow, and it is difficult to quickly adapt to the rapid changes in yarn tension; second, the complexity and maintenance cost of the hydraulic system are high, which increases the difficulty of using the equipment and the operating cost; finally, the adaptability of the hydraulic adjustment method is poor, and it is difficult to meet the processing requirements of air layer fabrics of different specifications and materials.

[0004] Therefore, it is very necessary to invent a warp knitting tension compensation device for air layer fabrics. Utility Model Content

[0008] Furthermore, the tensioning mechanism includes an outer shell, a vortex spring, a rotating column and a connecting plate, the outer shell is fixed to the inside of the side plate by bolts, and a vortex spring is arranged inside the outer shell, wherein the outer ring of the vortex spring is fixed to the inner wall of the outer shell; the inner ring of the vortex spring is fixed to the rotating column, wherein the rotating column is rotatably installed inside the outer shell through a support bearing; a connecting plate is fixed to one end of the rotating column by welding, wherein the first guide roller and the second guide roller are rotatably installed at both ends of the connecting plate through support bearings respectively, such an arrangement can effectively compensate for the tension of the air layer fabric.

[0009] Furthermore, the outer side surfaces of the first guide roller and the second guide roller are respectively provided with grooves adapted to the air layer fabric. Such an arrangement can prevent the air layer fabric from being deviated during movement.

[0012] 1. The setting of the tensioning mechanism of the utility model is that when the air layer fabric has too much or too little tightness, the connecting plate can rotate accordingly, and the elastic force of the vortex spring can effectively limit the displacement range of the first guide roller and the second guide roller, which can ensure the moderate tension of the air layer fabric in real time and avoid the situation where the air layer fabric is too tight or too loose.

[0013] 2.
