Detailed ways

The preferred embodiments of the utility model will be described in detail below in conjunction with the accompanying drawings, so that the advantages and characteristics of the utility model can be more easily understood by those skilled in the art, so that the protection scope of the utility model can be defined more clearly .

Please refer to accompanying drawing 1 to 4, the utility model embodiment comprises:

A soft fabric control mechanism, the Z-axis steering mechanism 1 of the hemming machine and installed on the sewing machine: pulley, timing belt, timing pulley, servo motor, round belt, belt assembly pulling cylinder 8, overlock auxiliary corner cylinder 9. The Z-axis steering mechanism 1 of the hemming machine is set on the front of the sewing machine. There is a round belt parallel to the sewing feeding plane outside the presser foot of the sewing machine. While the whole round belt can be lifted and lowered, there is also a round belt that can be pushed out at any time. Pulley, so that the purpose of gradually pressing the fabric can be achieved.

The belt assembly lifting cylinder 8 is fixed on the sewing machine, and the belt assembly fixing plate 7 is fixedly connected on the piston rod of the belt assembly lifting cylinder 8, and the belt assembly fixing plate 7 is vertically promoted by the belt assembly lifting cylinder 8.
