A Yarn Lead In Device For Automatic Piecing Units

Abstract: The present Invention discloses a yarn lead-in device for automatic piecing units, belongs to the field of textile equipment. The yarn lead-in device comprises a horizontal drive unit arranged on a mounting plate. The horizontal drive unit drives a vertical drive unit to move horizontally. The vertical drive unit drives a rotary drive unit to move vertically. The rotary drive unit drives a rocker arm to rotate. The yarn lead-in device designed in the present application can ensure that the rocker arm moves in the direction of the spindle through the horizontal drive unit during operation, while using the vertical drive unit to move in the vertical direction and using the rotary drive unit to piece yarns. At the same time, the improved installation layout of the rocker arm of the yarn lead-in device provides a higher positioning accuracy for automatic yarn piecing, and also provides an improved rigid support for the rocker arm without any overhang length, thus to piece yarns quickly and accurately through the device to improve the piecing efficiency of the automatic piecing unit.
