Automatic folding mold suitable for sewing of multiple types of pockets

Abstract

The invention relates to an automatic folding mold suitable for sewing of multiple types of pockets and a design method of the mold when the pocket size changes. The automatic folding mold comprises abase plate, a contact template, a tongue plate, a folding structure and an adjusting mechanism, wherein the contact template is arranged on the lower side of the base plate and is provided with a groove matched with a pocket cutting piece; the pocket cutting piece is arranged on the upper side of the supporting end of the tongue plate, and the corresponding edges of the pocket cutting piece respectively exceed the supporting end of the tongue plate and are dropped downwards; the tongue plate translates the pocket cutting piece to a position corresponding to the groove at the lower side of thecontact template; the folding mechanism folds the downwards dropped edges of the pocket cutting piece to a shape before sewing; and the adjusting mechanism is used for vertically adjusting the heightof the contact template to adapt to the pocket cutting pieces of different thicknesses. According to the automatic folding mold, when the thickness of the pocket cutting piece changes, the folding mold of the pocket does not need to be redesigned, the purposes of saving the labor and promoting the smooth development of a pocket sewing process are achieved, and the automatic folding mold has important significance in the field of pocket sewing equipment.

Description

technical field [0001] The invention relates to the field of clothing sewing equipment, in particular to an automatic folding mold suitable for sewing multiple types of pockets. Background technique [0002] figure 1 (a is the main view, and b is the side view) is a schematic diagram of the pocket panel 3 on the clothes before sewing. Within the size range of length L at one end of pocket piece 3, the thickness of the piece is t 1 , the thickness of the other pieces in the size range is t 2 , where t 2 ≥3t 1 . [0003] figure 2 Pocket rendering after sewing the pocket piece 3 after the clothes piece 6. The process requirements in the sewing process are: figure 2 The three corners of the pocket circled in the middle must have the effect of sharp corners. And each edge of the pocket after sewing does not allow redundant cut pieces to be exposed. [0004] The sewing work of current clothes pocket is mainly to be sewn smoothly by means of the effect of the pocket sew...

AI Technical Summary

Problems solved by technology

However, in the process of sewing with the help of the pocket folding mold, the dimensional relationship and action relationship between the parts in the mold are not specific, and it can only rely on continuous empirical adjustment according to the sewing effect during the working process, which is a waste of time. man-hours, adding additional time costs

[0005] In addition, when the thickness of the pocket pieces changes, the pocket folding mold will change to a large extent, and a new pocket folding mold needs to be redesigned. This will not only increase the man-hours, but also increase the design cost. and sales pressure

To a large extent, it restricts the smooth development of the pocket sewing process
