Wool yarn loosening mechanism for towel loom

Abstract

The invention relates to a wool yarn loosening mechanism for a towel loom. The wool yarn loosening mechanism for the towel loom comprises a wool yarn feeding servo motor, a speed reducer, a wool yarn shaft, a guide roller, a buffer elastic tube component, a tension control roller, an electricity box and a rack, wherein the wool yarn feeding servo motor drives and is connected with the wool yarn shaft, which is movably and rotationally connected onto the rack in a penetrating manner, through the speed reducer fixed on the rack and a large reduction gear and a small reduction gear, the wool yarn loosening mechanism further comprises two tension levers, one end or the middle part of each tension lever is movably hinged to the rack, or is fixedly connected with the buffer elastic tube component to rotate on the rack along with the buffer elastic tube component, or the middle part of each of the two tension levers is movably hinged to the rack, or is rotatably connected onto the buffer elastic tube component, a spring and a tension sensor are connected between the upper end of any tension lever and the rack in a pulling manner, a tension control roller is connected between the lower ends of the two tension levers, or the lower ends of the two tension levers are both connected with two support rolling pulleys, and the two support rolling pulleys abut against and drive the tension control roller; and the wool yarn shaft winds and feeds the wool yarn to the same sides of the buffer elastic tube component and the tension control roller after sequentially passing by the guide roller and reversing.

Description

technical field [0001] The invention relates to a towel machine, in particular to a hair loosening mechanism of the towel machine. Background technique [0002] The towel loom is a loom for weaving towel fabric. The ground warp yarn and the raised warp yarn are respectively sent out by two weaving shafts, and the weft yarn is pushed to the weaving fell through the specific regular movement of the reed, so that the raised warp yarn forms a loop on the surface of the fabric to weave Toweling fabric. Among them, the raising height is accomplished by instantaneously pushing more raising yarns through the reed. Traditionally, multiple tension axes and sensors are used to control the tension of wool feeding yarns, but when the tension exceeds, the tension axis releases the tension. In an instant, there is no tension on the wool yarn, which will easily cause the wool yarn to be pushed too much to the weaving mouth, and the wool height will be too high, which will affect the weavin...

Problems solved by technology

Among them, the raising height is accomplished by instantaneously pushing more raising yarns through the reed. Traditionally, multiple tension axes and sensors are used to control the tension of wool feeding yarns, but when the tension exceeds, the tension axis releases the tension. In an instant, there is no tension on the wool yarn, which will easily cause the wool yarn to be pushed too much to the weaving mouth, and the wool height will be too high, which will affect the weaving quality; and when the tension is too low, the tension on the wool yarn will be too high at the moment when the tension is tightened, which will easily cause the wool yarn to break , affecting normal weaving and reducing weaving efficiency

Moreover, when the yarn is initially fed after the yarn shaft is on the shaft, multiple tension shafts need to be disassembled, and it is time-consuming and labor-intensive to reinstall with the sensor. Once the installation error is very likely to affect the control of wool yarn tension and affect the weaving quality
