Seam spreading-open mechanism and seam spreading-open machine with seam spreading-open mechanism

Abstract

The invention relates to a seam spreading-open mechanism and a seam spreading-open machine with the seam spreading-open mechanism. The seam spreading-open mechanism comprises an operation table boardwhich is basically horizontally arranged. The spreading-open mechanism is characterized by further comprising a supporting plate, two rollers and a driving mechanism, the supporting plate is located on the operation table board, a gap allowing lower-layer cloth of double-layer cloth to penetrate through is reserved between the supporting plate and the operation table board, and the first side edgeof the supporting plate extends in the conveying direction of the cloth and is used for making contact with the sewing position of the double-layer cloth. The two rollers are arranged up and down andare adjacent to the first side edge of the supporting plate, the extending directions of the axes of the two rollers are consistent, and a gap for the double-layer cloth to pass through is formed between the two rollers; and the power output end of the driving mechanism is in driving connection with the corresponding rollers, so that at least one layer of cloth in the double-layer cloth in the gap is driven to move in the direction away from the first side edge. In the whole seam spreading-open process, only the two rollers need to be matched with the first side edge of the supporting plate,and the seam spreading-open effect is good.

Description

technical field [0001] The invention belongs to the technical field of garment processing, and specifically relates to a seam-removing mechanism and a seam-removing machine having the seam-removing mechanism. Background technique [0002] In the processing technology of the garment factory, one process is to peel the two layers of sewn fabric apart along the seam gap to make the seam gap pattern more beautiful. At present, in this process, operators manually perform the seaming operation along the gaps, which is time-consuming and labor-intensive. [0003] In order to solve the above technical problems, for example, the Chinese utility patent "A Sewing Machine", whose patent number is CN201920243154.1 (authorization announcement number is CN 209890860 U), discloses a sewing machine that includes an auxiliary device for supporting the sewing material. The feeding plate has an auxiliary feeding wheel on the auxiliary feeding plate. The frame is provided with a mounting bracke...

Problems solved by technology

The above-mentioned patent realizes automatic seam removal, but requires the cooperation of the first feed wheel, the second feed wheel, the third feed wheel and the auxiliary feed wheel to achieve the purpose of seam removal, and the structure is relatively complicated. In addition, the three feed wheels are in the In the process of pulling the fabric, uneven pulling may occur, resulting in uneven seams
