The flat knitting machine completes the knitting of the garment pieces by the knitting needle assembly arranged on the needle bed through the running track of turning needles, knitting, tuck stitching, needle transfer and the like. In general computerized flat knitting machines, knitting needles are arranged flat on a needle bed, the yarn feeder is fixed on the yarn feeder seat, and is arranged straight above the knitting needle plane, and the bottom end of the yarn feeder is kept at a distance from the knitting plane. A computer horizontal knitting machine is provided with multiple yarn feeder seats, all of which are fixed with yarn feeders. After presetting the program in the computerized flat knitting machine, each yarn feeder seat will send the knitting wire worn on the yarn feeder to the position of the corresponding knitting needle as needed. After the knitting needle bounces, the knitting wire is hung and knitted. Because of the product's color and other requirements, different yarn feeders need to be replaced to run to the same orientation to cooperate with the knitting needle. At this time, if the distance between the different yarn feeder and the needle plane is the same, the needle will collide with the suspended yarn feeder. Cause damage to the knitting needle and yarn feeder. There are two existing solutions, the first is to move the suspended yarn feeder seat out of the knitting area; the second is the German yarn feeder seat, the yarn feeder fixed on the yarn feeder seat is not straight when it is disabled Down, but offset to the left or right by an angle (compared with the straight setting, the distance from the needle plane is significantly increased), a wrench is set on each of the two tentacles on the left and right of the yarn feeder seat, which needs to be used During the yarn feeder seat, the machine head slides on the yarn feeder seat through the slide rail, knead the wrench on the tentacle, adjust the yarn feeder to the straight setting for knitting; if you need to change to another yarn feeder seat, Then, the machine head slides out from the direction of the other tentacle of the yarn feeder seat. During the sliding process, the wrench is kneaded on the tentacle to adjust the yarn feeder to the deflection angle. The first method mentioned above, because the yarn feeder seat is frequently used during product weaving, if every time the yarn feeder is brought out of the knitting range, it will cost a lot of knitting materials and reduce the knitting power; the yarn feeder of the second method Produced in Germany, the structure is messy and the production cost is high.
The skill problem that the flat knitting machine has to solve is to provide an efficient computerized flat knitting machine. The method of controlling the yarn feeder position by the computer flat knitting machine that overcomes the existing skills causes the disadvantages of low knitting power, waste of knitting materials, and messy control structure. The disadvantage of high cost. The skill plan used to solve the above skills problem is
Efficient computerized flat knitting machine, including machine head and machine head slide rail, a yarn feeder seat is provided on the machine head slide rail, a yarn feeder is provided on the yarn feeder seat, between the yarn feeder seat and the yarn feeder A return spring is provided, the tail end of the return spring abuts the yarn feeder seat, and the head end of the return spring abuts the yarn feeder. When the machine head applies pressure to the yarn feeder, the yarn feeder is relative to the yarn feeder The seat is displaced downward. When the machine head does not apply pressure to the yarn feeder, the tension of the return spring causes the yarn feeder to move upward relative to the yarn feeder seat. According to an implementation example, a protrusion is provided on the inner side of the yarn feeder, and the head end of the return spring abuts the protrusion. According to an implementation example, the yarn feeder seat is provided with a recessed portion, and the tail end of the return spring abuts against the inner side of the recessed portion.
