Description

Transferring needle

Technical field

The invention relates to the field of knitting technology, in particular to a transfer knitting needle.

Background technique

A primary looping mechanism on a knitting machine that is machined from steel or steel strips for weaving the yarn into a loop and joining the loops of the loop into a knitted fabric. The improvement of knitting needles has promoted the development of knitting machines. Humans were first hand-woven with a stick. In 1589, W. Lee invented the crochet and appeared the first knitting machine. More than 200 years later, the tongue, groove needle and double-headed needle were invented, which opened up a new way for the development of knitting machines. The structure and shape of the knitting needle affect the knitting process, the productivity of the knitting machine and the quality of the product, which are important basis for the knitting machine design. Commonly used knitting needles are three kinds of tongue, crochet and compound needle.

The needle has a needle with a tongue. During the looping process, the yarn is woven into a coil by reciprocating along its length. When the tongue moves relative to the yarn, the tongue is rotated by the old coil on the needle bar, and the needle is closed, so that the yarn under the needle hook and the old coil are respectively on both sides of the needle tongue. As the needle moves further, the yarn passes through the old coil to form a new coil.

The crochet has a needle with a hook. During the looping process, the yarn is moved relative to the old coil to form a new coil with the sinker. In order to close the needle, it is convenient for the string of the old coil, and there is no needle groove on the crochet to accommodate the tip of the hook. The crochet is simpler in structure than the tongue, easy to manufacture, and can weave thinner fabrics, but other looping machines that are compatible with it are more complicated, and have applications on weft knitting machines and warp knitting machines. There is also a crochet that automatically closes the needle, which is called a self-closing crochet and is used on a crochet machine.

The compound needle is a needle composed of a needle body and a needle core. During the looping process, the core moves along the needle body, opening or closing the needle to form a coil. The movement of the compound needle during the looping process is smaller than that of the tongue and the crochet, which creates conditions for the knitting machine to increase productivity.

Regarding the method of moving the needle, the existing knitting needles are all moving in a straight line manner, which can set more suitable needle grooves and knitting needles under the circumference of the unit diameter when the vertical single needle knitting is performed, and the conventional The upper dial adopts a horizontal straight needle. Due to the radial movement, the knitting machine of the upper dial cannot set more suitable needle grooves and knitting needles on the circumference of the unit diameter. The horizontal needle can only be looped and transferred in the case of the number of needle slots and the number of stitches, and can not be circled and transferred in the case of more needle slots and stitches, thus limiting the braided fabric. quality.

Therefore, in order to promote the development of knitting, further improvement of the knitting needle and the way of moving the needle is required.

Due to the curved structure of the transfer needle, the needle movement method is different. Compared with the straight needle, the circular needle knitting needle can set more needle grooves and needles than the horizontal needle in the circumference of the same unit diameter. At the same time, it has the method of horizontal needle dispensing. The curved transfer knitting needle combined with the straight needle can set the advantages of multi-needle groove and multi-needle number and the advantages of horizontal needle out of the needle to form a circle or transfer, and there is no horizontal The needle can not set more needles and needles on the horizontal dial of the unit diameter circumference. The advantage of the curved transfer needle is that the bottom end of the needle rod does not move toward the center of the dial when working, so the needle The bottom end of the rod does not collide together, so more needle grooves and needle numbers can be set on the circumference of the dial with the same caliber and on the syringe. The method of the arc-shaped needle-drawing needle of the present invention effectively solves the unit. The circumference of the caliper dial cannot set more problems with the needle groove and the knitting needle.

Compared with the prior art, the invention has the following beneficial effects:

Traditionally, the dial cannot be set with more needle grooves and knitting needles in the circumference of the unit diameter. This application adopts a curved transfer knitting needle method, because the end direction of the curved transfer knitting needle is not toward the dial or the syringe. In the direction of the center of the circle, more needle grooves and needles can be placed on the dials and syringes of the same diameter, so that the requirements of knitting more new and higher quality braids can be achieved, and the fashion sense and competitiveness of the products can be increased.
