Sweater fabric loop variable-needle-pitch automatic alignment transfer type sewing machine

Abstract

The invention relates to a sweater fabric loop variable-needle-pitch automatic alignment transfer type sewing machine. The machine comprises a transfer pin plate, a push plate, a transfer pin and groove pin alignment unit and a dial linking machine or a groove pin plate, wherein the transfer pin plate is arranged on one side of the dial linking machine in the tangential direction or one side of the groove pin plate in parallel. When a dial of the dial linking machine rotates by the length of one groove pin pitch or the groove pin plate moves horizontally by the length of one groove pin pitch, the transfer pin plate moves by the length of one transfer pin pitch synchronously in the tangential direction or horizontal movement direction, and the transfer pin pitch can be identical with or different from the groove pin pitch of the dial linking machine or the groove pin pitch of the groove pin plate. The transfer pin and groove pin alignment unit is arranged above or below the transfer pin aligned with the corresponding groove pin and acts on the transfer pin to enable the transfer pin to deform to be aligned with the groove pin. The push plate is arranged at the alignment position above the transfer pin and groove pin alignment unit and reciprocates once synchronously between the transfer pin plate and the dial linking machine or the groove pin plate each time the transfer pins and the groove pins move by a corresponding pin stitch, so that coils on the transfer pins are pushed onto the corresponding groove pins. The machine has the advantages that sewing efficiency and quality are improved.

Description

Technical field [0001] The invention involves weaving machinery, which specifically involves the veneer of the sweater fabric coil. Background technique [0002] The sweater woven fabrics and collar and attachments are woven separately, and then sutured by sewing machine. Before suture, weaving the woven collar and attachments need to be transferred to the seam machine. [0003] At present, the collar and attachments that are woven from the weaving machine are transferred to the sewing machine. The manual method is generally used. Because the collar and attachments are generally woven by a dense needle method, there are many coils to be transferred.People with detailed operations cannot be competent, and the work efficiency is limited by the capability of the operator. Once the operation time is long, even the best operator may have a needle leakage. ThereforeNone of the high requirements can be met, and the cost of employment is high.
