Description

Technical field: [0001] The invention belongs to the field of textiles, and relates to a mechanism for fixed and regular winding of yarn layers of a sample warping machine. Background technique: [0002] With the increasingly fierce market competition and the variety of textiles and the rapid update, the sample warping machine is gradually favored by textile enterprises, because it simplifies the original processing with large yarn consumption, long process flow and slow response speed. link, so the machine is a powerful tool for new product development and fabric trial weaving, figure 1 It is a traditional fixed creel warping machine. The AC variable frequency motor 10 drives the driving shaft 13 to rotate through the toothed wheel 11, the toothed belt 12, and the toothed wheel 11', and then the driving shaft 13 rotates to drive the yarn winding. Rod 7 rotates, is driven by servomotor 14 through sprocket 15, chain 16, sprocket 15 ', sprocket 15 ", chain 16 ', gear box 17 a...

Problems solved by technology

Its working process is that the yarn 1 is pulled out from the bobbin 2, passes through the yarn guide plate 3, the tensioner 4, the tension ring 5, bypasses the support disc 6, and is wound onto the drum A by the yarn winding finger 71 of the yarn winding rod 7. Inclined block 8 until it slides on 16 toothed conveyor belts 9 distributed along the circumference of drum A, then toothed conveyor belt 9 carries yarn 1 and moves to the right end to form a yarn layer. After the number of turns n' (n' is the quotient of the warping length of the weaving beam divided by the circumference of the cylinder), the toothed conveyor belt 9 will move a certain distance (the center distance between the two warp yarns on the weaving beam). This traditional yarn layer winding The method is called the fixed width winding method. In the actual winding process, the regular winding of the yarn layer cannot be realized, which makes the collapse of the warp yarn layer very serious. The order of yarn stacking is disordered, and the unwinding of the yarn on the cylinder is hindered when the weaving beam is wound, and the warping effect will be poor. Therefore, the warping length is usually only 30 to 40 meters

[0003] In order to increase the warping length, there is a method of regular winding of the yarn layer - direct winding method (Direct Winding), such as figure 2 As shown in the figure, the inclined block 8 is fixed on the drum A, and it is used as a stable support for the yarn layer. As the winding progresses, the yarn winding finger 71, the pin shaft 25, and the yarn guide plate 26 are constantly moving to the right. At the same time, the yarn guide plate 25 rotates and swings around the pin shaft 26 to discharge the yarn. The stacking structure of the yarn layer is relatively regular, and the unwinding effect is good, which is conducive to increasing the warping length. However, this method cannot be warped according to the process design. Yarns are arranged according to the density, so it is not possible to fix the width, which brings great troubles to the rewinding of the weaving beam. At the same time, its structure is complex and occupies a large area, so it is not easy to transplant and modify on the existing sample warping machine.
