[0002] Compact spinning, also known as compact spinning, is modified from the ring spinning frame. Its core technology is to install a gathering device at the output end of the front roller, so that the slivers are gathered and then output for twisting, realizing the separation of drafting and gathering, avoiding the influence of friction distribution due to the existence of gathering effect in the drafting area, and the width of the slivers after drafting is reduced after gathering, so that the twisting triangle area is reduced or even eliminated, thereby eliminating the adverse effects caused by the existence of the twisting triangle area and improving the yarn quality. The gears that transmit power between the bridge gear rollers are installed on the lower side of the compact spinning negative pressure mechanism. The traditional bridge gear is exposed and cotton wool is easily embedded in the bridge gear, causing transmission failure. There is also a safety hazard that the operator may accidentally touch the bridge gear and cause injury. Utility Model Content
