Background
When the computerized flat knitting machine starts, the starting needle adopted comprises a grooved needle swing rod assembly and a groove needle swing rod, when the grooved needle swing rod assembly moves upwards, the swing rod swings left and right to hook the machine head yarn, and then moves downwards until the machine head yarn is pulled out of the roller and is looped off.
The applicant has filed a starting needle patent with patent number 2008100604152, which is a starting needle of a flat knitting machine and comprises a grooved needle and a swing rod, wherein the grooved needle is provided with a longitudinal groove, a main body of the swing rod is accommodated in the groove, as shown in fig. 1, the grooved needle 5 is rectangular as a whole, and U-shaped openings 51 are correspondingly arranged on the two side groove walls of the grooved needle; the head part of the upper end of the swing rod is in a 7-shaped hook shape, the width of the head part is smaller than the width of the groove wall on one side of the U-shaped opening, the lower end of the swing rod extends out of the longitudinal groove of the grooved needle, and the swing rod is rotatably connected with the grooved needle and can swing left and right in the longitudinal groove of the grooved needle. The grooved needle passes through the rivet combination with the pendulum rod, through the pendulum rod horizontal hunting and mutually support with grooved needle U type opening and hang the yarn and take off the yarn, but because original grooved needle 5 comprises two metal complex, the head cross-section of the longitudinal groove of grooved needle is inverted V style of calligraphy structure 52, and two metals are with acute angle amalgamation, and there is the gap between two metals, and there is gap 53 in the acute angle department that two metals formed inverted V style of calligraphy promptly, as shown in fig. 2. Therefore, after the swing rod loosens the yarn, the gap in the middle of the head of the grooved needle is easy to hook the yarn of the machine head, and the grooved needle cannot hook or fall off the yarn when hooking the yarn.
Disclosure of Invention
The invention aims to solve the problems and provides a yarn hooking prevention grooved needle swing rod assembly which can close a gap at the head of a grooved needle so as to reduce yarn hooking of the grooved needle.
Therefore, the technical scheme of the invention is as follows: a yarn hooking prevention grooved needle swing rod assembly comprises a grooved needle and a swing rod, wherein the grooved needle is provided with a longitudinal groove and is formed by splicing groove walls on two sides, a swing rod main body is accommodated in the groove, the grooved needle is integrally rectangular, and U-shaped openings are correspondingly formed in the groove walls on the two sides of the grooved needle; the head part of the upper end of the swing rod is in a 7-shaped hook shape, the width of the head part is smaller than the width of the groove wall on one side of the U-shaped opening, the lower end of the swing rod extends out of the longitudinal groove of the grooved needle, and the swing rod is rotatably connected with the grooved needle and can swing left and right in the longitudinal groove of the grooved needle; the method is characterized in that: step surfaces are arranged at the upper ends of the groove walls on the two sides of the groove needle, the groove walls on the two sides above the step surfaces are tightly attached by taking the step surfaces as boundaries, the groove walls on the two sides below the step surfaces form longitudinal grooves, and the step surfaces on the groove walls on the two sides form the top ends of the longitudinal grooves; the step surfaces on the two sides are higher than the head of the swing rod.
Furthermore, step surfaces on groove walls on two sides of the groove needle are of an inclined structure, and after the groove walls on the two sides are spliced, the step surfaces on the two sides are connected with each other at an obtuse angle, namely the top end of the longitudinal groove is at the obtuse angle; the step surfaces at two sides are positioned above the U-shaped opening on the groove wall.
In the invention, the U-shaped opening at the upper end of the groove needle is beneficial to better entering of yarns, and is convenient for the swing rod to hang and doff yarns. The ridge part at one side of the grooved needle is opened, a longitudinal groove is formed on the main body of the grooved needle, and the swing rod is installed in the longitudinal groove of the grooved needle from the opening part. The slot needle and the swing rod can be riveted by a rivet, and the swing rod can swing left and right in the slot needle. When the starting needle hangs the yarns, the swing rod rotates relative to the grooved needle, the 7-shaped hook-shaped head at the upper end of the swing rod swings to the U-shaped opening of the grooved needle and is exposed out of the U-shaped opening of the grooved needle, and the yarns are hung; when the starting needle is used for doffing, the swing rod rotates relative to the grooved needle, the hook-shaped head of the swing rod swings to one side of the U-shaped opening of the grooved needle and is hidden in the groove wall on one side of the U-shaped opening, at the moment, yarn is blocked by the side face of the U-shaped opening of the grooved needle to be doffed, and therefore the yarn hanging and doffing functions are achieved through the left-right swing of the hook-shaped head of the swing rod and the mutual matching of the hook-shaped head of the swing rod and the U-shaped opening of the grooved needle.
According to the invention, the step surface is processed at the head of the grooved needle by changing the processing technology of the grooved needle, and the groove wall above the step surface is tightly attached, so that the head of the grooved needle is flattened, the gap is closed, and the problem of yarn hooking of the grooved needle is reduced. Meanwhile, the step surfaces increase the connecting angles of the groove walls on the two sides, and the obtuse angle is more difficult to hook yarns compared with the acute angle, so that the computerized flat knitting machine can work normally.
