Control system of sock head sewing machine and sock head sewing machine equipped therewith

Abstract

The invention discloses a control system for sock head sewing machine, comprising an electric power supplement portion, a motor driving portion, a microcomputer control portion, and a signal detection portion, which is characterized in the motor driving portion comprises a feeding device motor driving circuit, a first sewing device motor driving circuit, a second sewing device motor driving circuit, a delivery device motor driving circuit, a sewing device lifting motor driving circuit. Each motor driving circuit is correspondingly connected with motor on each device. The microcomputer controlportion comprises a touch screen or a keyboard, a liquid crystal display and microcomputer. Motor driving circuits, the touch screen or the keyboard, the liquid crystal display, and the signal detection portion are all electrically connected with the microcomputer. The control system of the sock head sewing machine uses a microcomputer control portion to control individual driving circuits for driving corresponding motors, has advantages of precise and accurate control, smooth and artistic sock head sewing wire. The invention further discloses a sock head sewing machine having the control system.

Description

technical field [0001] What the present invention relates to is a kind of machine that is used for suturing the toe of a sock, especially relates to the control system of this machine. Background technique [0002] The traditional sock sewing machine transports socks by more than a thousand small needles moving in a circular motion to trim and seam. The small needles on the disc are fragile and easy to wear, the operation speed is slow, and the production efficiency is low. In order to be able to solve this problem, just someone has invented a kind of sock sewing machine with high working efficiency. Check the Chinese patent database, and one of them is called "Linear Sock Seaming Machine", and the announcement number is a utility model patent of CN200952072 Y, which discloses the following content: "Linear Sock Seaming Machine, including a guide frame and a lower conveyor chain device, lower chain transmission box, trimming device, three-needle sewing machine head box, mai...

AI Technical Summary

Problems solved by technology

The sock toe sewing machine with this structure greatly improves the production efficiency; however, due to the elastic effect of the fibers at both ends of the sock toe, it will shrink, resulting in the shape of the middle of the sock toe and the bottom at both ends.

The straight-line sock sewing machine mentioned above can only sew the toe in a straight line, and the sock after the sewed line is uncomfortable to wear, because the sock toe after shrinkage cannot be stitched in a curved line, which makes the toe of the sewed uneven , and also due to the straight line stitching, the seam leakage phenomenon caused by the two ends of the sock toe is not in place, so that the stitched socks appear defective

At the same time, due to the above-mentioned linear sock sewing machine, due to the imperfection of its control system, the speed of the corresponding motor cannot be controlled, resulting in uneven density of the toe seam, especially at the seam when the machine starts and when the machine stops. Severe unevenness occurs, causing quality problems after the toe is sewn
