Description

Anti-rolling device of automatic seam splicing machine Technical Field The invention relates to the technical field of sewing machines, in particular to an anti-rolling device of an automatic seam splicing machine. Background In the field of modern sewing machines, full-automatic sewing equipment is generally adopted, compared with traditional sewing equipment, the full-automatic sewing equipment can obtain more efficient sewing efficiency, reduces physical burden of operators, and can reduce safety risks, so development is relatively rapid, and in the sewing process, the cloth pieces can be folded due to the drawing of a sewing needle, and particularly in the splicing process, the folding among different cloth pieces can bring errors to the sewing of the cloth pieces, and the situation that the splicing seams are askew and different in tightness occurs. For example, publication number CN212955631U discloses a cloth stitching mechanism for a stitching flag machine, which comprises a first stitching mechanism and a second stitching mechanism which are arranged oppositely, wherein the front ends of the first stitching mechanism and the second stitching mechanism are provided with a first feeding component and a second feeding component, the first stitching mechanism is used for stitching two cloth, and the second stitching mechanism is used for stitching one cloth on the cloth processed at the first stitching mechanism. However, in practical application, due to the pulling of the sewing needle in the sewing process, the cloth piece around the sewing position can be folded, and the folding can cause deviation in sewing, so that the sewing position is too tight or too loose, and the flatness of the cloth piece on the feeding device can be further affected. Disclosure of Invention Aiming at the problem that more folds are generated on a cloth piece by pulling a sewing needle in the prior art in the background art, the invention provides an anti-rolling device of an automatic sewing machine, which can fix and flatten a piece to be spliced, ensure the flattening state of the piece to be spliced when the piece to be spliced enters a sewing position, and simultaneously have a certain tensioning effect on the piece to be spliced, so that more displacement is avoided when the piece to be spliced is pulled by the sewing needle. In order to achieve the above purpose, the present invention adopts the following technical scheme. The utility model provides an automatic seam machine prevents rolling up device, is including the pay-off plane, the transmission has the sheet of waiting to splice on the pay-off plane, pay-off plane side is provided with the sewing machine head, the pay-off plane is provided with elasticity at one end that is close to the sewing machine head and prevents rolling up board, elasticity prevents rolling up board can the butt wait to splice the sheet, elasticity prevents rolling up board will wait to splice the sheet and press on the pay-off plane. Be provided with the conveyer belt on the pay-off plane, the piece that waits to piece that places on the pay-off plane can be along with the carrying out transmission motion of pay-off plane in the sewing process, thereby imitate the pay-off feeding step in the manual processing process, the sewing machine head carries out sewing processing to the piece that waits that the conveying was coming, the elasticity that is close to the one end of sewing machine head along the direction of delivery set up prevents rolling up the butt on waiting to piece, make waiting to piece and can extrude the laminating on the pay-off plane, produce certain relative reverse pulling force to waiting to piece in the motion, make waiting to piece's surface tensioning, thereby reduce sewing machine head processing and to wait to piece's pulling influence, make waiting to piece and prevent rolling up between version and the pay-off plane before entering into the sewing region simultaneously, eliminate waiting to piece's deformation clearance, guarantee waiting to piece's roughness.
