Technical Field

Background

With the development of science and technology, the automation technology is mature day by day, wherein the traditional manual production of the mask is gradually replaced by the existing automatic production; in the automatic production operation of the mask, an ear wire weaving device is adopted to weave ear wires. The process of weaving the ear wire by the existing ear wire weaving device is as follows: firstly, two groups of unwinding assemblies are used for unwinding two braided wires respectively; then, weaving the two weaving wires into the ear wires by a weaving machine head; and finally, the wire take-up assembly is used for accommodating the ear wires woven by the weaving machine head. The existing machine head generally comprises a middle core rod, a lower core, an upper core, a crochet hook and a shell; when in work: a curve groove forming a certain included angle with the horizontal plane is formed by the bottom end face of the upper movement, the top end face of the lower movement and the inner wall face of the shell, the bent part at the bottom of the crochet hook is inserted into the curve groove, and then a driving wheel on an external motor output shaft and a transmission wheel arranged on the outer peripheral side of the lower movement form a belt transmission to drive the shell to rotate through a rubber rope; then, when the upper core and the lower core rotate synchronously along with the shell, the circular motion of the curved groove is converted into the up-and-down motion of the crochet hook in the crochet hook groove of the central core rod, and the knitting of the ear line is finished by the alternate up-and-down motion of a plurality of crochet hooks.

The rotating speeds of the upper core and the lower core need to be improved in order to improve the knitting efficiency of the editing machine head, but the bottom end face of the upper core and the top end face of the lower core are directly abraded rapidly when the rotating speeds of the upper core and the lower core are too high, so that the service life of the machine head is shortened, and the upper stroke and the lower stroke of a crochet hook are inaccurate, so that the knitting of an ear line is influenced.

Thus, the prior art is subject to improvement and advancement.
