AI Technical Summary

Technical Problem

Existing seamless knitting machines are prone to axial displacement and swaying during the rotation of the yarn roller, resulting in yarn instability. Furthermore, when the yarn stops being released, inertia causes the yarn to loosen, affecting the knitting quality.

Method used

It employs positioning and adjustment components, including folding plates, discs, guide pillars, screws, cylinders, and other structures, to ensure the stability and tension consistency of the yarn roller during rotation by limiting and adjusting the position and tension of the yarn roller.

Benefits of technology

It effectively prevents axial displacement and inertial relaxation of the yarn roller during rotation, improves the versatility of the yarn roller and the quality of weaving, and ensures that the yarn maintains stable tension during weaving.

Abstract

The utility model discloses a seamless knitting machine, and relates to the technical field of seamless underpants cloth production equipment. Comprising a seamless knitting machine body, a fixing frame, a positioning assembly arranged at the bottom of the fixing frame and used for limiting and fixing a yarn roller, and an adjusting assembly arranged on the outer side of the fixing frame and used for braking the yarn roller and adjusting yarn tension. Under the action of the arc-shaped plate, the yarn roller can be supported, the screw is used for driving the folded plates below the fixed seat to move horizontally, the distance between the folded plates can be adjusted, and therefore the yarn roller is limited, axial displacement of the yarn roller in the rotating process is avoided, the yarn roller limiting device can adapt to yarn rollers of different lengths, and then the yarn roller limiting device is suitable for yarn rollers of different lengths. In the process that the fixed shaft drives the disc to rotate, the disc drives the guide columns to move along the guide grooves, so that the guide rods are driven to slide along the fixed shaft, the area of a circle formed by the arc-shaped plates can be adjusted, the yarn rollers with different inner diameters can be matched, and the compatibility of the seamless knitting machine is improved.
