AI Technical Summary
Technical Problem
In the existing yarn feeding mechanism of circular knitting machines, it is difficult to detect in time when the yarn runs out or breaks, resulting in a decline in production efficiency and quality, low efficiency of manual monitoring, and difficulty in locating faults.
Method used
A yarn feeding device was designed, comprising a vertical plate, guide rollers, a fixed frame, a fixed pulley, a movable pulley, a buffer block, a trigger, and an audible and visual alarm. The device triggers the alarm to alert workers by changes in yarn tension and assists in quickly locating the fault.
Benefits of technology
It enables timely alarms and rapid fault location when yarn runs out or breaks, improving yarn replacement efficiency and ensuring production efficiency and quality.

Abstract
The yarn feeding device of the circular knitting machine comprises a base, the upper surface of the base is fixedly connected with a stand column, a vertical plate and a fixing frame respectively, the surface of the stand column is sleeved with a sleeve, the lower end of the sleeve is fixedly connected with a supporting plate, the upper end of the stand column is fixedly connected with a limiting plate, and the upper end of the vertical plate is movably connected with a guide roller through a bearing. The two sides of an inner cavity of the fixing frame are movably connected with two fixed pulleys through bearings, buffer grooves are symmetrically formed in the middle of the inner cavity of the fixing frame, the tops of the buffer grooves are fixedly connected with triggers, buffer blocks are slidably connected into the buffer grooves through guide blocks, and the lower surfaces of the buffer blocks are fixedly connected with embedding rods. Through cooperation of the vertical plate, the guide roller, the fixed frame, the fixed pulley, the movable pulley, the buffer block, the embedded rod, the main spring, the trigger and the audible and visual alarm, the state of yarn in the yarn feeding device can be detected in real time, workers can conveniently and rapidly position the yarn, and the efficiency of replacing or overhauling the yarn by the workers is improved.
