Description

Improved structure of circular weaving machine

Technical Field

The invention relates to a circular weaving machine structure, in particular to an improved structure of a circular weaving machine which drives a circular weaving machine to weave warps in a non-contact mode.

Background

At present, the weaving process of the traditional circular weaving machine is woven by output yarns in a warp and weft staggered mode. Referring to fig. 1 and 2, the warp yarn of the conventional circular knitting machine is moved longitudinally by a belt pulley 1 to output the yarn, and then the yarn is interlaced with the weft yarn, and the belt pulley 1 is driven continuously by a power shaft 2, a disc 3, a guide 4 and a swing arm 5.

Specifically, the power rotating shaft 2 is longitudinally arranged at the center of the machine table, the disc 3 is annularly connected to the outer periphery of the power rotating shaft 2, so that the power rotating shaft 2 synchronously drives the disc 3 to rotate at a high speed, and the guide piece 4 is far away from the power rotating shaft 2 and convexly arranged on one side surface of the disc 3, wherein the guide piece 4 is in a wave curve shape; as shown in fig. 2, the guiding member 4 and the pulley set 1 are connected to each other by a swing arm 5, and the swing arm 5 is transversely pivoted to a fixing member 6, so that the swing arm 5 can swing longitudinally relative to the disc 3; two rollers 7 are disposed at one end of the swing arm 5 away from the pulley set 1, and the two rollers 7 are movably disposed on the guiding member 4, so that when the disc 3 drives the guiding member 4 to move, the two rollers 7 of the swing arm 5 longitudinally displace along the track of the guiding member 4, thereby driving the pulley set 1 to longitudinally move.

However, the conventional circular knitting machine has the following defects in the warp knitting process:

(1) two rollers 7 of the swing arm 5 are movably and slidably disposed on the guiding member 4 in a contact manner, so that when the disc 3 drives the guiding member 4 to move at a high speed for a long time, the two rollers 7 and the guiding member 4 generate high-speed friction, thereby accelerating the service life of the two rollers 7, and thus frequent replacement and maintenance are required, and the additional cost of production is increased.

(2) The swing arm 5 is transversely pivoted on the fixing member 6, so that when the two rollers 7 of the swing arm 5 longitudinally displace along the track of the guiding member 4, the end of the swing arm 5 connected to the pulley set 1 can generate longitudinal arc-shaped swing, which causes the pulley set 1 to move to generate deviation, and also affects the moving speed of the pulley set 1, thereby generating the problem of reducing the warp knitting efficiency.
