Abstract

The invention provides a reverse stitching device which comprises a swing seat, wherein a supporting shaft is arranged in the middle of the swing seat; the lower part of the swing seat is connected with an automatic reverse feed driving mechanism; the automatic reverse feed driving mechanism comprises a connector; one end of the connector is hinged with the lower part of the swing seat; the other end of the connector is connected with the output end of a reverse feed bracing wire; and the input end of the reverse feed bracing wire is connected with a bracing wire driving part. According to the reverse stitching device disclosed by the invention, the reverse feed bracing wire with flexible transfer acting force is used, and the reverse stitching noise can be effectively reduced.

Description

technical field [0001] The invention relates to the technical field of reverse stitching structure, in particular to a reverse stitching device. Background technique [0002] Existing lockstitch machine carries out the structure of reverse sewing, such as figure 1 As shown, the transmission of force between the electromagnet 11 and the swing seat 12 is realized through the automatic reverse feeding rod group, and the collision between the feeding adjustment stud 13 and the regulator 14 realizes the limit when the reverse sewing is converted. In this structure, the automatic reverse feed rod group includes the automatic reverse feed pull rod 15, the automatic reverse feed crank 16 and the automatic reverse feed input rod 17 connected in sequence, the automatic reverse feed pull rod 15, the automatic reverse feed crank 16 and the automatic reverse feed input rod 17 The large matching gap between them will produce noise, and the collision between the feeding adjustment stud 13...
