Problems solved by technology

Generally speaking, the upper thread is wound on the bobbin, so the upper thread is longer; while the length of the bobbin thread wound on the bobbin winding post is very limited, so during the uninterrupted working process of the sewing machine, the bobbin winds every once in a while. The bobbin thread on the bobbin will be used up, requiring the operator to frequently wind the bobbin thread on the bobbin bobbin bobbin and replace the empty bobbin, thus reducing sewing efficiency

Abstract

The invention relates to the field of sewing auxiliary equipment, and discloses an automatic shuttle peg replacement device which comprises a fixed box. A first driving part parallel to the axis of arotating shuttle is arranged in the fixed box, a feed bin for placing a standby bobbin case is arranged on the first driving part and provided with a movable fastener for clamping the bobbin case, themovable fastener is connected with a second driving part for driving the movable fastener, the feed bin is provided with a fixed fastener matched with the movable fastener, the fixed fastener is connected with a third driving part for driving the fixed fastener to move in a vertical direction, a shuttle bar connected with the third driving part is arranged at the upper end of the feed bin, a plurality of clamp slots for embedding the standby bobbin case are formed in the lower surface of the shuttle bar, and the side face of the feed bin is provided with a fourth driving part for driving theshuttle bar to horizontally move. By coordination of the four driving parts, the movable fastener, the fixed fastener, the shuttle bar and the feed bin, the device can automatically replace a shuttlepeg, and manual replacement is omitted, so that sewing efficiency is improved.

Description

technical field [0001] The invention relates to the field of sewing auxiliary equipment, in particular to an automatic bobbin changing device and an automatic bobbin changing method. Background technique [0002] A sewing machine is a machine that uses one or more sewing threads to form one or more stitches on the sewing material to interweave or sew one or more layers of sewing material. The sewing machine can sew fabrics such as cotton, fiber crops, silk, wool, and artificial fibers, and products such as leather, plastics, and paper. [0003] When the sewing machine is sewing the fabric, the rotary hook and the needle of the sewing machine cooperate with each other to interweave the bottom thread and the upper thread and sew them on the fabric to form stitches. The rotary hook includes a bobbin, and the bobbin is accommodated in the bobbin case, and the bottom thread is wound on the winding post of the bobbin. Generally speaking, the upper thread is wound on the bobbin, ...
