Shoe upper computer sewing machine

Abstract

The invention discloses a shoe upper computer sewing machine. The shoe upper computer sewing machine comprises steel wire spring clamps, stitches, starting points, ending points, stitch templates and stitch through grooves, wherein the stitch templates are arranged below shoe side fabrics; the stitch through grooves are formed in the stitch templates; the stitches are arranged in the stitch through grooves; the starting points and the ending points are arranged on the heads and the tails of the stitches; the shoe upper fabrics are fixed on a sewing machine motion platform through a plurality of steel wire spring clamps. The shoe upper computer sewing machine has the advantages of simple structure and good sewing effect, and a sewn shoe upper pattern is high in consistence; moreover, a plurality of machines can be operated simultaneously, so that the production efficiency is increased greatly.

Description

technical field [0001] The invention relates to the field of sewing processing, in particular to a computerized sewing machine for shoe uppers. Background technique [0002] When the traditional computer sewing machine sews shoes, due to the poor fixing effect, it is easy to produce misalignment, and the patterns sewn by different shoe sizes are not the same, resulting in defective products, which greatly reduces the efficiency and efficiency of shoe upper sewing. quality. At present, the stitching of the upper in the shoemaking industry all adopts the working method that the motor is driven to control the stitches by manual feeding. This has just caused the quality of sewing products to be unstable and the production efficiency to be low. [0003] At present, computerized lockstitch sewing machines and embroidery machines cannot sew vamps well. The reason is that in the existing equipment: ①The mobile platform supports the workpiece with cloth or the like as the board su...

AI Technical Summary

Problems solved by technology

[0003] At present, computerized lockstitch sewing machines and embroidery machines cannot sew shoe uppers very well.

The reason is that in the existing equipment: ①The mobile platform supports the workpiece with cloth or the like as a board surface to carry the workpiece, which cannot guarantee the service life for the graphics that use the same track for a long time, and the workpiece shakes up and down during the processing process, front and rear, left and right chatter, making processing inaccurate

②In the existing equipment, the workpieces are fixed by adhesive tape or the like. One by one operation is complicated, wastes materials, and the efficiency is low. It is difficult to fix our workpieces.

③Pressure foot of existing equipment Some adopt the roller type, but if the needle running track (relative to the workpiece) is a non-linear line such as a curve or a circle when sewing, the rolling direction of the roller and the direction of the needle movement cannot be consistent

If the seam is curved or round, the same as The task cannot be completed as described

Some presser feet press the workpiece by random needle movement up and down, which solves the problem However, the workpiece cannot be pressed down before the needle penetrates into the workpiece, nor can it be pressed down when the needle is pulled out of the workpiece, causing the workpiece to shake up and down when the needle reciprocates into and out of the workpiece.

Therefore, the suture stitches deviate from the correct track, making the stitches unattractive, resulting in large processing deviations
