Abstract

The invention discloses an automatic bottom shuttle replacing device which comprises a bobbin case taking mechanism and a bobbin taking mechanism, wherein the bobbin case taking mechanism is used for grabbing a bobbin case, and the bobbin taking mechanism is used for taking out a bobbin from the bobbin case and winding a new bottom line on the bobbin. When the bobbin taking mechanism takes out the bobbin from the bobbin case, a connecting line between the bobbin case and the bobbin is cut off by the aid of a line cutting mechanism, a residual line on the bobbin case is reserved, the new bottom line is connected with the residual line on the bobbin case by the aid of a connecting mechanism after the new bottom line is completely wound on the bobbin, and the bobbin is placed into the bobbin case by the bobbin taking mechanism to serve as a spare part.

Description

technical field [0001] The invention relates to a sewing machine, in particular to an automatic bottom shuttle device for changing 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 c...
