Synchronous cylinder shaping device installed on circular weaving machine

Abstract

The invention provides a synchronous cylinder shaping device installed on a circular weaving machine, and belongs to the field of achieving heat shaping of fabrics with thermoplastic fibers through high-frequency electromagnetic induction heating. The device solves the technical problems that surfaces of the unshaped fabrics with the thermoplastic fibers are wrinkled, the size is not stable, the woven fabrics with the thermoplastic fibers have to be preshaped in a dying and finishing procedure, and the process is complicated. According to the technical scheme, a high-frequency induction heating device is installed between a weaving device and a gray fabric dragging and rolling device of the circular weaving machine. The cylinder woven fabrics slip off from the surface of a high-frequency induction heating cylinder so as to be shaped after the fabrics are woven and before the fabrics come out of the circular weaving machine. The synchronous cylinder shaping device has the advantages that the shaped woven fabrics are obtained on the circular weaving machine, the preshaping processing for the fabrics in the dying and finishing procedure is eliminated, and the problems that traditional process equipment is large in investment, long in process procedure, high in energy consumption, high in repairing rate and the like are solved.

Description

technical field [0001] The invention relates to a gray cloth setting device of a circular knitting machine, in particular to a high-frequency electromagnetic induction heat setting device installed on a circular knitting machine. Background technique [0002] Knitted fabrics containing thermoplastic fibers are irregular and wrinkled due to various stresses and extrusions during the parking process. Therefore, most knitted fabrics containing thermoplastic fibers need pre-setting treatment before dyeing to obtain a good Dimensional stability and appearance flatness. The current pre-setting process has the following defects: [0003] Because it is completed on the stenter setting machine or cylinder high-temperature setting machine in the dyeing and finishing workshop, the equipment investment is large, the process flow is long, and the energy consumption is high. [0004] Due to the retraction of the fibers before the rough is unshaped, the fabric is easy to form dead folds ...

Problems solved by technology

[0003] Because it is completed on the stenter setting machine or cylinder high temperature setting machine in the dyeing and finishing workshop, the equipment investment is large, the process is long, and the energy consumption is high.

[0004] Due to the retraction of the fibers before the blank is unshaped after the blank is off the machine, the fabric is easy to form dead folds due to extrusion and stacking, resulting in repair or degrada
