Sock head sewing machine

Abstract

The invention discloses a stocking toe sewing machine comprising a power supply part, a motor drive part, a microcomputer control part and a signal detection part; and the machine also comprises a feeding device, a tailoring device, a lift sewing device and a conveying device. The machine is characterized in that the motor drive part is provided with a main motor drive circuit and a lift motor drive circuit with the lift sewing device; the microcomputer control part comprises a touch screen or a keyboard, a liquid crystal display and a microcontroller; the motor drive circuit, the touch screen or keyboard, the liquid crystal display and the signal detection part are all electrically connected with the microcontroller; and the tailoring device, lift sewing device and conveying device are connected with a main motor in a transmission manner. The stocking toe sewing machine has the advantages that the control is precise and the stocking toe seam is neat.

Description

Technical field [0001] The invention relates to a machine used for sewing the toe of a sock, and particularly relates to a sewing machine controlled by a microcomputer. Background technique [0002] The traditional sock stitching machine conveys socks with more than a thousand small needles moving in a circular motion into the trimming and seaming head. The small needles on the disc are fragile and easy to wear, the running speed is slow, and the production efficiency is low. In order to solve this problem, someone invented a high-efficiency sock sewing machine. Check the Chinese patent database, one of which is named "Linear Sock Sewing Machine", and the announcement number is a utility model patent of CN200952072Y. The sock toe stitching machine with this structure greatly improves the production efficiency; however, the two ends of the sock toe will shrink due to the elastic effect of the fibrous material, resulting in the shape of the high end of the toe. The above-mentioned ...

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 straight line is sewed is uncomfortable to wear, and since the sock toe after shrinkage cannot be sewed in a curved line, the sock toe sewn is not smooth, In addition, due to the straight line stitching, the two ends of the sock toe are not sewn in place and the seam leakage phenomenon is caused, so that the stitched socks are 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 at the place, causing quality problems after the toe is sewn
