Abstract
A warp knitting machine comprises a box body, a grooved needle bed, a needle core bed, a loop removing sheet, a transmission mechanism, a guide bar, a traversing device, a yarn feeding device, a tension adjusting device, a frame and the like, and forms a warp knitting machine capable of knitting four-side weft insertion fabrics. The guide bars may be divided into oblique weft insertion guide bars, longitudinal weft insertion guide bars, transverse weft insertion guide bars and knitting chain guide bars. The oblique weft insertion guide bar is driven by the ball screw to transversely move, and the single transverse movement amount is matched with the transverse row to form an oblique tissue. The two groups of oblique weft insertion guide bars can be used for left-oblique and right-oblique yarn-backing. The transverse weft insertion guide bar is a transverse yarn feeder, and air flow is sprayed out by an air nozzle to carry the yarn to transversely pass through so as to form a single-row full-width transverse yarn-laying. The longitudinal weft insertion guide bar is that the same needle of yarn or the same longitudinal interval needle back yarn is used for forming longitudinal tissues in the weaving process. And then a knitting chain guide bar forms a loop to sleeve the yarns in the transverse direction, the longitudinal direction, the left oblique direction and the right oblique direction to form the fabric with four weft inserted directions.
Description
Technical Field
The invention relates to a warp knitting machine for knitting special cloth, in particular to a structure of a super warp knitting machine, and belongs to the field of textile equipment.
Background
In the current market, the structural principle of the full weft insertion warp knitting machine is that yarns on a creel behind a machine platform are converted into 45 degrees by a yarn feeder and fed into a rear comb position of the full weft insertion warp knitting machine, then 45 degrees of yarns are upwards jacked from the bottom of the whole piece of 45 degrees of yarns by a grooved needle, when the 45 degrees of yarns are jacked to the front of the grooved needle, yarns of a knitting chain are padded before the grooved needle hook, then the grooved needle hook is closed by a needle core, at the moment, the whole piece of 45 degrees of yarns slide upwards from the bottom of the needle core, a looping structure is formed after the yarns slide out of the grooved needle head, and a 45 degrees weft insertion structure is formed on the cloth surface. Such a looping structure has two problems: firstly, yarns are sent to the back of a warp knitting machine by a yarn feeder, then the average degree of each yarn is in front of each grooved needle by any upward ejection of grooved needle hooks, so that 2 yarns are ejected by some grooved needles, only half yarns are ejected by some grooved needles, the whole cloth is uneven, and some yarns F are ejected by needle heads and broken; secondly, the yarns can only be used for whole piece of disordered yarn, and each yarn can not be used for being clearly padded in front of each grooved needle, so that the cloth with no deformation due to four-side stress can not be achieved. And the machine has complex structure and large occupied area.
Disclosure of Invention

The guide bars can be divided into an oblique weft insertion guide bar, a longitudinal weft insertion guide bar, a transverse weft insertion guide bar and a knitting chain guide bar, and a warp knitting machine capable of knitting weft insertion fabrics in four directions is formed. The method is characterized in that: the four-side weft insertion fabric is formed by knitting guide bars to form loops, and the transverse, longitudinal and oblique yarns are sleeved to form the fabric with four weft insertion directions.
Further, the oblique weft insertion guide bar is arranged below the hanger seat, a sliding block is connected to the top of the hanger seat, and the sliding block is matched with a lower guide rail arranged on the main beam. The oblique weft insertion guide bar drives the hanger seat through the ball screw, the sliding block is pulled to transversely move left and right on the guide rail, and the single transverse movement amount is matched with the transverse row to form an oblique tissue. The ball screw is driven by a servo motor.
Further, the oblique weft insertion guide bars are divided into two groups, and the two groups of oblique weft insertion guide bars can be used for left-oblique and right-oblique two-direction yarn-laying.
Further, the set of oblique weft insertion bars may be comprised of more than one oblique weft insertion bar, and when one oblique weft insertion bar is cumulatively shone in one direction to complete the yarn-laying of the full-width fabric, the yarn-laying may be shoved in the opposite direction.
Further, the oblique weft insertion guide bar is fed by a creel, and the yarns pass through a tension adjusting device and pass through a yarn collecting plate, and the yarn collecting plate moves along with the oblique weft insertion guide bar.
Further, the tension adjusting device is a yarn return device. The yarn returning device is fixed under the radial shaft bracket. The yarn passes through the yarn return device, so that the problem of partial yarn tightness is adjusted, and the tension of each yarn before entering the loop is consistent.
Further, the yarn return device consists of a yarn return shaft and two yarn feeding shafts, and the middle yarn return shaft is provided with a servo motor. The yarn returning shaft and the yarn feeding shaft are consistent in steering, and when the yarn is tight, the yarn feeding shaft rotates clockwise along with the traction force of the yarn; when the yarn is loose, the yarn returning shaft timely adjusts the yarn tension.
Further, the yarn collecting plate is arranged at the top of the hanger seat and moves along with the oblique weft insertion guide bar, so that the yarn compensating effect during left-right movement is achieved.
Further, the transverse weft insertion guide bar, namely the transverse yarn feeder, is provided with air flow sprayed by an air nozzle to transversely pass through the yarn, so that a single-row full-width transverse yarn-laying can be formed.
Further, the transverse yarn feeder is arranged at the position of the machine head wallboard, and each transverse yarn feeder feeds yarns from the machine head to the machine tail in each transverse row, and each yarn acts as a transverse yarn-laying function.
Further, the longitudinal weft insertion guide bar is the same needle as the yarn or the same longitudinal interval needle backing yarn, and forms a longitudinal tissue in the weaving process.
Further, the yarn included angle formed by the oblique weft insertion guide bar and the longitudinal weft insertion guide bar is about 30-60 degrees.
Further, the knitting guide bar forms loops to sleeve the yarns in the transverse direction, the longitudinal direction, the left oblique direction and the right oblique direction, and forms the fabric with the weft inserted in all four directions.
Further, both the knitting chain guide bar and the longitudinal weft insertion guide bar adopt pan head yarn feeding.
Further, the oblique weft insertion guide bar, the longitudinal weft insertion guide bar, the transverse weft insertion guide bar and the knitting chain guide bar can be combined at will, and are not limited to four guide bars.
The beneficial effects of the invention are as follows: a super warp machine has a pair of grooved needles for knitting the oblique, longitudinal and transverse yarns formed by oblique, longitudinal and transverse weft insertion bars. The four sides are stressed, so that the cloth which is uniform in cloth and is not deformed due to the stress of multiple sides can be produced, and the cloth can be used as a conveyer belt, a special cloth for military cloth and the like.
