Control method for independent intelligent pressure root drive mechanism of embroidery machine

Abstract

The invention relates to a control method for an independent intelligent pressure root drive mechanism of an embroidery machine. The control method comprises the following steps: a step motor driving step, a pressure foot driving step and an eccentric wheel positioning step. The control method solves such technical problems of stitch skipping, yarn breaking, sewing material deviating and the like caused by the reason that the embroidery machine in the prior art can not embroider thick material and leather fabric, the position of the pressure foot is high and far from the needle plate, the tension of the yarns is small and the inclined angle is large; the yarns cannot be tightened in a process of embroidering thick yarns and thick materials; the frictional force of the needle and the sewing material is large, the pressure of the pressure root is insufficient in a recycling and raising process, and the fabric is raised by the needle; the control method is free of any influence of needle rod driving, stitch skipping and yarn breaking phenomenon, has the advantages of simple intelligent operation, uniform thick embroidered material and leather fabric stitch density, high embroidering speed, good quality, and the like.

Description

technical field [0001] The invention belongs to the technical field of control of an independent presser foot drive system influenced by needle bar drive, and in particular relates to a method for controlling an intelligent independent presser foot drive mechanism of an embroidery machine. Background technique [0002] Embroidery machine, also known as embroidery machine, is a sewing machine used for embroidery. The working method of traditional mechanical embroidery machine is: replace the sewing machine with a bottom plate with a small round hole, the needle keeps going in and out, and then use the hand-held embroidery frame, Hold the cloth taut. However, with the introduction of electronic technology into the field of sewing machines in 1975, the functional characteristics of embroidery were added to the computerized sewing machine, and the mechanical embroidery machine entered the era of computer-controlled mechatronics from mechanical control. Based on the microproces...

Problems solved by technology

[0006] The object of the present invention is to provide a control method for the intelligent independent presser foot drive mechanism of an embroidery machine, which solves the problem that the embroidery machine in the prior art cannot embroider thick materials and genuine leather fabrics through stepping motor drive steps, presser foot drive steps, and eccentric wheel positioning steps. , the work of the presser foot is high, far away from the needle plate, the tension of the thread is small, the inclination angle is large, the stitches cannot be tightened when embroidering thick threads and thick materials, the friction between the needle and the sewing material is too large, and the presser foot is raised when it is recovered If the pressure is insufficient, the fabric will be taken up by the needle, which will lead to technical problems such as skipped stitches, thread breakage, and sewing material movement. , Embroidery thick materials and genuine leather fabrics have uniform stitch density, high embroidery speed, good quality and other beneficial advantages
