Abstract

The embodiment of the invention provides an automatic shearing device for sewing residual threads and a gas transmission structure thereof. The automatic shearing device comprises the gas transmission structure, an actuator and a cutter structure; the gas transmission structure comprises a shell cover, and a gas transmission pipe is arranged in the shell cover and comprises a gas suction section and a conveying section; an air inlet hole communicated with the air suction section and the conveying section and an exhaust hole communicated with the conveying section are formed in the shell cover, and a suction inlet is formed in the end, away from the conveying section, of the air suction section; the actuator is fixed in the shell cover; the cutter structure is arranged above the actuator; and the cutter structure comprises a cutter holder, a fixed cutter and a movable cutter matched with the fixed cutter for shearing, wherein the suction inlet is formed below the shearing position of the fixed cutter and the movable cutter. Therefore, the labor operation cost can be saved, and the production efficiency can be improved.

Description

technical field [0001] The present application relates to the technical field of sewing machines, in particular to an automatic cutting device for residual sewing thread and its air delivery structure. Background technique [0002] Sewing machines are distinguished according to the sewing style, which can be roughly divided into two categories: lock stitching (Lock Stitching) and chain stitching (Chain Stitching). On the other hand, at least one needle that holds the needle thread and moves up and down forms a needle loop under the needle plate, and performs the forward and backward movement in a direction approximately perpendicular to the up and down motion path of the needle The advance of the thread hook catches the needle loop, and the captured needle loop is looped with other threads by the hook thread held by the thread hook, thereby forming a chain seam stitch at the sewn part of the cloth. [0003] Among them, chain stitches are mostly used in decorative sewing suc...
