Abstract

The invention discloses a sewing machine bottom shuttle replacing method. The sewing machine bottom shuttle replacing method is characterized by comprising the steps of taking out a first shuttle casing from a shuttle table of a sewing machine base and installing a standby second shuttle casing in the shuttle table; taking out a first shuttle peg from the replaced first shuttle casing, cutting off a bottom line connected between the first shuttle peg and the first shuttle casing and clamping a remaining line of the first shuttle casing through a remaining line clamping device; removing the bottom line left on the first shuttle peg, winding a new bottom line fully and connecting the newly-wound bottom line to the remaining line on the first shuttle casing; installing the first shuttle peg into the first shuttle casing for standby. The whole shuttle replacing steps are simplified, the shuttle replacing efficiency is improved, automatic operation is facilitated through various mechanisms, the steps of taking the shuttle casings and the shuttle peg of a bottom shuttle of the sewing machine, winding the line on the shuttle peg, installing the shuttle peg into the shuttle casing, installing the shuttle casing into the shuttle table and the like can be automatically achieved, accordingly automatic bottom line replacement of the sewing machine is achieved, 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 bottom shuttle of the sewing machine. Background technique [0002] A shuttle compartment is arranged in the base of the sewing machine, and a bobbin case is installed in the bobbin case. The bobbin with a bottom thread is installed in the bobbin case, and the sewing work is performed in cooperation with the needle. Because industrial sewing machines usually work non-intermittently, and the amount of winding 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 for someone to take care of and replace the bobbin with the bobbin thread. [0003] Patent name: A device used to replace the bobbin used for stitching on sewing or embroidery machines. Patent No.: 200580011462.2 discloses a shuttle changing device. By gripping the bobbin case cover on the bobbin case, the shuttle Take out the shell. A plurali...
