Description

Technical Field

[0001] The utility model relates to the technical field of textiles, in particular to a self-correcting yarn feeding device for a textile fabric warp knitting machine. Background Art

[0002] A knitted fabric is formed by simultaneously forming loops on all the working needles of the warp-feeding machine with one or several groups of parallel yarns. This method is called warp knitting, and the fabric is called warp knitted fabric. The machine that completes this warp knitting is called a warp knitting machine. The warp knitting machine is mainly composed of a weaving mechanism, a comb slidable mechanism, a warp feeding mechanism, a pulling and winding mechanism, and a transmission mechanism. The main loop-forming parts of the warp knitting machine are knitting needles, guide needles, sinkers, and pressing plates (for crochet machines). The knitting needles are mounted on the needle bed in an row and move with the needle bed. The guide needles are mounted on the strips to form a comb. The warp yarn passes through the holes of the guide needles, moves with the comb and is wrapped around the needles. The fabric is woven through the coordinated movement of the knitting needles, sinkers and other loop-forming parts.

[0003] The continuous deviation of the deviation corrector during the yarn feeding process will make the yarn conveying speed unstable, which may cause excessive force on the yarn locally, resulting in uneven yarn tension, which will interfere with the normal feeding speed of the yarn and make it difficult to maintain a constant warping speed, thereby reducing production efficiency.

[0006] By providing a warping machine body and a correcting assembly, before the yarn enters the warping roller, the driving motor in the correcting assembly is started to drive the bidirectional lead screw to rotate, and the fixed mounting part at the center position of the outer side of the bidirectional lead screw is fixed to the bottom end of the inner wall of the warping machine body to play a supporting role. When the bidirectional lead screw rotates, the symmetrical sliding parts on its outer side will adaptively adjust along the lead screw according to the width of the yarn, and the connecting frame and the mounting plate on the top of the sliding part will move accordingly, and the connecting rod on the connecting frame will also move along, and the multiple correcting pulleys on the outer side of the connecting rod correct the yarn by their own position changes, so that it can enter the warping roller more accurately. In the process, accurate correction can make the yarn arranged neatly when entering the warping roller, so that the distribution of the yarn after warping is more uniform, which improves the speed of warping and thus improves the efficiency of the entire production process.

[0008] By arranging a buffer spring, a telescopic rod, an auxiliary pad, an auxiliary round rod, a motor frame, a warping roller, an auxiliary guide roller, an electric rotating rod, a rotating shaft and a belt, when the yarn is corrected, the buffer spring and the telescopic rod on the top of the mounting plate are compressed or extended, and the upper auxiliary pad flexibly contacts according to the real-time state of the yarn to buffer the impact of the yarn and assist in correcting the deviation to avoid damage to the yarn and components. At the same time, the auxiliary guide roller on the inner wall of the warping machine body guides the yarn forward and assists its transition to the warping roller. After the electric rotating rod is started, it drives the rotating shaft to rotate, and the belt outside the rotating shaft moves accordingly.

The outside of the movable rod is fixedly connected with symmetrical fixing parts, and the bottom ends of the fixing parts are fixedly connected to the bottom ends of the inner walls of the warp-biased machine body. The fixing parts are located in front of the symmetrical movable frames, and the top of the movable frames is fixedly connected with connecting plates, the top of the connecting plates is fixedly connected with angle offset plates, and the top of the angle offset plates is fixedly connected with multiple separation round rods.

[0010] By providing a deviation correction component, when the warping machine is working, the movement of the belt drives the linkage shaft to rotate, and the linkage shaft then drives the vertical bevel gear to rotate. Since the vertical bevel gear and the transverse bevel gear are tightly meshed through the tooth grooves, when the vertical bevel gear rotates, the transverse bevel gear will rotate synchronously. While the vertical bevel gear rotates, the symmetrical fixings fixed on the outside of the movable rod secure the movable rod to the bottom end of the inner wall of the warping machine body, ensuring that the rotation trajectory of the movable rod is stable, and the movable frame moves with the linkage shaft; the connecting plate on the top of the movable frame drives the angle offset plate to swing, and the multiple separation round rods on the top of the angle offset plate begin to separate the yarns. These separation round rods accurately separate and straighten the entangled or stacked yarns according to the set movement trajectory and angle, so that the yarns are evenly dispersed, so that they can enter the warping roller and other processes more smoothly in the subsequent processes, thereby improving the fineness and quality of yarn processing and ensuring the efficient and orderly progress of the textile process.
