A sewing machine that imitates artificially pushed materials

Abstract

The present invention proposes a sewing machine that imitates manual pushing of materials, including a sewing machine base, on which a column sewing table, a sewing needle bar and a side block are arranged; the sewing machine base also includes an optical fiber sensing mechanism, an edge correcting device and an edge correcting control system, the optical fiber sensing mechanism includes an upper optical fiber sensor and a lower optical fiber sensor corresponding to the upper and lower sides of the sewing material, and the edge correction device includes an edge correction fulcrum mechanism with an edge correction fulcrum pin and an edge correction feed with a rotatable edge correction feed wheel Mechanism, when the sewing material deviates, the corresponding sensing ends of the upper optical fiber sensor and the lower optical fiber sensor are connected and fed back to the edge correction control system, and the edge correction device is controlled to correct the position of the sewing material. The present invention provides a sewing machine that imitates artificially pushing materials, which can mechanizedly push artificially imitated materials, thereby realizing high-precision sewing of sewing materials, satisfying high sewing efficiency, and facilitating industrialized processing.

Description

technical field [0001] The invention relates to the technical field of high-end machines, in particular to a sewing machine that imitates manual pushing of materials. Background technique [0002] The high-head sewing machine in the prior art comprises a sewing machine base, on which a column sewing platform, sewing presser wheels and sewing needle bars are arranged. When using a high-end sewing machine for sewing, first of all, you need to use a pen to draw the corresponding lap line on the corresponding sewing material according to the template. uniform, and then meet the sewing requirements; then the sewing material is fixed on the column sewing table through the sewing presser foot, and the side stopper corresponding to the sewing line of the sewing material is set on the column sewing table, that is, when performing manual sewing, only need It is enough to correct the position of the sewing material in the direction of the side stopper. Since the laying line is mostly ...

AI Technical Summary

Problems solved by technology

When using a high-end sewing machine for sewing, first of all, you need to use a pen to draw the corresponding lap line on the corresponding sewing material according to the template. Evenly, and then meet the sewing requirements; then the sewing material is fixed on the column sewing table through the sewing presser foot, and the side block corresponding to the sewing line of the sewing material is set on the column sewing table, that is, when performing manual sewing, only need It is enough to correct the position of the sewing material in the direction of the side block. Since the laying line is mostly a curve, during the feeding and sewing process, the operator generally needs to turn and feed the material according to the direction of the laying line; During overlapping sewing, only one hand is needed to feed the material; when sewing two pieces of fabrics to overlap the edge, the operator needs to use the left and right hands to push at the same time, to test the proficiency of the operator, once the position of the sewing material deviates ( Deviation specifically means that during the sewing process, the sewing material will deviate in the direction away from the side block. When continuing to sew, the sewing needle bar will not contact the sewing material, and empty seams will occur.) There are problems such as incomplete sewing and uneven stitches, which affect the aesthetics and pass rate of the product. The probability of waste or defective products is relatively high, which greatly increases the manufacturing cost.
