Embodiment Construction

[0008] Below in conjunction with accompanying drawing and specific embodiment the present invention will be described in further detail:

[0009] see figure 1 , the automatic sewing machine eiderdown automatic exhaust device of the present invention comprises an exhaust fan 1, an automatic template sewing frame 2, two air pipes 3 and a template 4, and the template 4 is installed on the automatic template sewing frame 2, and the template 4 is also installed There is a down cut piece 5, and the exhaust fan 1 communicates with both sides of the down cut piece 5 through two air pipes 3 respectively.

[0010] The two air pipes 3 are detachably inserted on both sides of the down panel 5 respectively.

[0011] Before sewing, two air pipes 3 are respectively inserted into the down cut pieces 5, and the exhaust fan 1 is automatically turned on during sewing to take away the air in the down cut pieces 5, which effectively prevents the down cut pieces 5 from expanding too much, thereby ...

Abstract

The invention discloses an automatic down air drafting device for a full-automatic sewing machine. The automatic down air drafting device comprises a suction fan, an automatic template sewing frame, two air pipes and a template, wherein the template is mounted on the automatic template sewing frame, a down cut-part is further mounted on the template, and the suction fan is communicated with the two sides of the down cut-part through the two air pipes respectively. Before sewing, the two air pipes are inserted in the down cut-part; in the sewing process, the suction fan starts automatically to draft away air in the down cut-part, and the down cut-part is effectively prevented from swelling excessively; hence, in the automating sewing process, the cut piece will not crease, and uniform down filling is guaranteed.

Description

technical field [0001] The invention relates to a full-automatic sewing machine, in particular to an automatic blower for down of the full-automatic sewing machine. Background technique [0002] Since the manual lockstitch sewing machine needs to be operated manually, the technical level of the operator is high, the labor intensity is high, and the production efficiency and yield are not high. Therefore fully automatic sewing machines have begun to replace manual lockstitch machines and have been widely used. However, all fully automatic sewing machines face a problem when sewing down-filled pieces. Because the down-filled garment pieces are relatively swollen, they will catch the cloth and down during sewing, resulting in wrinkled sewing and uneven down. Therefore need a kind of device to be able to guarantee that the garment cut piece does not expand when sewing, avoids wrinkling and down unevenness. Contents of the invention [0003] The technical problem to be solved...
