Abstract

The invention discloses a method for automatically winding a bottom line of a bobbin. A bobbin case is provided with the bobbin. The method includes the steps: arranging a new bottom line to be wound outside a shaft hole of the bobbin, enabling the new bottom line to penetrate the shaft hole of the bobbin through a winding shaft, and fixing the new bottom wire into the shaft hole of the bobbin; taking out the bobbin from the bobbin case by moving the winding shaft, pulling the new bottom wire to be wound to a line winding surface of the bobbin through a line pulling hook, driving the winding shaft to rotate through a winding motor, and winding the new bottom line on the bobbin. The winding motor on a base is matched with the winding shaft, the bobbin can be automatically taken out, the line can be automatically wound, and the efficiency of replacing the bobbin and the bottom line is improved.

Description

technical field [0001] The invention relates to a bottom shuttle of a sewing machine, in particular to a method for automatically winding the bottom thread of a bobbin. Background technique [0002] The base of the sewing machine is provided with a shuttle chamber, and a bobbin case is installed in the shuttle chamber, and a bobbin with a bobbin thread is installed in the bobbin case, and cooperates with machine needles to carry out sewing work. Because industrial sewing machines usually work non-stop, and the amount of thread wound on the bobbin is very small, the bobbin thread on the bobbin will run out every once in a while, so it is necessary to arrange special personnel to take care of and replace the bobbin with the bobbin thread wound on it. [0003] Patent name: A device used to replace the bobbin for looping threads on a sewing or embroidery machine. Patent No.: 200580011462.2 discloses a shuttle changing device. By grasping the bobbin case cover on the bobbin case,...
