Abstract

The cloth feeding and fastening mechanism of numerically controlled single needle quilter includes a right fixing board and a left fixing board, a right oscillating board and a left oscillating board connected separately to the right and the left fixing board, an upper roller with ends connected through bearing seats to the oscillating boards, a lower roller with ends connected fixed on the fixing boards, cylinders with telescopic ends hinged separately to the upper end of the oscillating boards, a motor with output shaft connected through a chain and tension pulleys to the rollers to drive two rollers to rotate in the opposite direction. The present invention tenses, conveys and cuts the sewn fabric.

Description

technical field [0001] The invention belongs to a quilting device for a bed cover or a mattress fabric, in particular to a tensioning mechanism of a numerically controlled single-needle quilting machine. Background technique [0002] Numerical control single-needle quilting machine has attracted more and more attention because of its strong sewing thickness and high complexity of quilting patterns. The last process of the CNC single-needle quilting machine is to send out the finished fabric and cut it according to the required length. When cutting, the fabric must be tightened, because the fabric is loose, and the cross-cutter cannot cut the fabric smoothly. Contents of the invention [0003] The object of the present invention is to solve the above-mentioned technical problems and provide a tensioning mechanism of a digitally controlled single-needle quilting machine capable of smoothly feeding out and tensioning fabrics. [0004] The purpose of the present invention is ...
