Abstract

The invention discloses a shuttle peg replacing method. The shuttle peg replacing method comprises the steps of taking out a shuttle peg from a shuttle casing, pulling a connecting line between the shuttle casing and the shuttle peg to the position of a cutter blade to be cut off, reserving a remaining line on the shuttle casing, clamping the end of the remaining line on an elastic line clamping piece, removing the waste line on the shuttle peg and winding a new bottom line on the shuttle peg, connecting the end of the new bottom line to the end of the remaining line, and then installing the shuttle peg into the shuttle casing for standby. By adopting the shuttle peg replacing method, the shuttle peg taking, winding of the new bottom line, bottom line and remaining line connection and other operations are achieved automatically, accordingly the trouble that a specially-assigned person monitors the operation is avoided, and the labor cost is reduced.

Description

technical field [0001] The invention relates to a sewing machine, in particular to a method for replacing the bobbin of the bottom shuttle of the sewing machine. 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, the sh...
