Problems solved by technology

This has resulted in unstable quality of sewn products and low production efficiency
[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 use the roller type, but if the needle running track (relative to the workpiece) is a non-straight 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

Abstract

The invention discloses a computerized sewing machine for shoe uppers, which comprises steel wire spring clips, stitches, a starting point, an end point, a stitch template, and a stitch channel. , There are stitches in the stitch channel, the beginning and the end of the stitches are the starting point and the end point respectively, and the upper fabric is fixed on the sewing machine movement platform through a plurality of steel wire spring clips. The invention has the advantages of simple structure, good sewing effect, good pattern consistency of the sewn vamp, and can operate multiple sets, greatly improving the production efficiency.

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...
