Machine for seaming socks head

Abstract

The invention discloses a lockstitch looper, which comprises a feed device (2), a tailor device, a stitch device, a transmission device, a waste recycle device (16) and a frame (11), and is characterized in that the feed device is driven by a feed motor (15), the tailor device and the transmission device are driven by a transmission motor (10), the stitch device is driven by a stitch motor, the feed drive motor, the transmission motor and the stitch motor are controlled by a microcomputer, and the stitch device is connected with a lift device for lifting the stitch device upwards and downwards in the working condition. The stitch device is connected with the lift device after each device in the lockstitch looper is controlled by the microcomputer through the individual motors, further the automation degree is high, the feed, tailor and stitch speed can be adjusted, thereby the stitch density of the lockstitch and the stitch speed can be adjusted, the curve stitch can be done in the lockstitch, which enables the lockstitch to be wore durably, flatly and beautifully.

Description

technical field [0001] The invention belongs to the technical field of sewing machines, in particular to a sewing machine used to sew stocking toes. 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, main motor, body platform, electrical b...

AI Technical Summary

Problems solved by technology

The sock toe sewing machine with this structure greatly improves the production efficiency; however, due to the elasticity of the fibers at both ends of the sock toe, it will shrink, resulting in a shape with a high middle of the outer toe and a 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 straight line sock sewing machine, the structure of the upper conveyor chain device is simple, so that the stitching coil of the toe of the feed is not smooth, which will lead to uneven trimming, uneven toe of the sock, and unevenness after sewing. quality problem
