Yarn layer breadth-determining spinning mechanism of warper

Abstract

The present invention discloses a constant size profiling winding device for the yarn layer of sample piece beaming machine features that it also includes a guide rod frame on the inner wall of which are guide rods in uniform distribution, three rack bars are extended on the left bottom of its outer ring, and three toothed gears and three stepping motors are arranged on the left bottom position. The invention accomplishes constant size profiling yarn discharging method by simple structure.

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 of large yarn consumption, long process flow and slow response. link, so this machine is a powerful tool for new product development and fabric sample trial weaving. US Patent No. 4,972,562 and US No. 5,950,289 refer to the traditional fixed creel sample warping machine shown in Figure 1, which is controlled by AC frequency conversion The motor 10 drives the drive shaft 13 to rotate through the toothed wheel 11, the toothed belt 12, and the toothed wheel 11', and then the drive shaft 13 rotates to drive the yarn winding rod 7 to rotate, and the servo motor 14 pas...

Problems solved by technology

Its working process is that the yarn 1 is drawn out from the bobbin 2, passes through the guide plate 3, the tensioner 4, the tension ring 5, bypasses the support disc 6, and is wound by the yarn winding finger 71 of the yarn winding rod 7 to the inclined wire on the drum A. block 8, until it slides on 16 toothed conveyor belts 9 distributed along the circumference of the drum A, then the toothed conveyor belt 9 carries the 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 distance between the centers of the two warp yarns on the weaving beam). This traditional yarn layer winding method It 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 layer very serious. If the warping length is increased (the number of turns n' increases), the yarn on drum A The order of thread 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, the yarn layer regular winding method involved in U.S. Patents US2002050038A1 and US5,630,262 - Direct Winding (Direct Winding) is shown in Figure 2, and the oblique block 8 is fixed on the drum A as a yarn Relying on the stability of the layer, as the winding proceeds, the yarn winding finger 71, the pin shaft 25, and the yarn guide plate 26 continuously move to the right, and at the same time, the yarn guide plate 25 rotates and swings around the pin shaft 26 to arrange the yarn, and the pile of yarn layers The base structure is relatively regular, and its unwinding effect is good, which is conducive to increasing the warping length. However, this method cannot arrange the yarn according to the warping density designed by the process, so it cannot be fixed, and it will bring great damage to the rewinding of the weaving beam. Trouble, at the same time, its structure is complex, occupying a large area, it is not easy to transplant and transform on the existing sample warping machine
