A 3D mesh sewing machine

Abstract

The invention provides a 3D mesh cloth sewing machine. The 3D mesh cloth sewing machine comprises a sewing device, and a material supply device for conveying a large amount of 3D mesh cloth to the sewing device; the sewing device comprises a sewing rack, and a sewing table which is mounted on the sewing rack and through which the large amount of 3D mesh cloth horizontally pass; a plurality of sewing units are arranged in a row on the sewing rack, wherein the plurality of sewing units are arranged at equal intervals in the width direction of the sewing table to synchronously sew the large amount of 3D mesh cloth on the sewing table in a single line manner; each sewing unit comprises a sewing needle which is positioned above a corresponding sewing opening and can act up and down, and a rotating shuttle which is positioned below the corresponding sewing opening and matched with a quilting seam. With the adoption of the 3D mesh cloth sewing machine, a single line is used only for sewing, a backing line is not required to be mounted, and thus the use is convenient; the plurality of sewing units are used for directly sewing through a single needle and the single line at a time, so that the working efficiency is improved.

Description

technical field [0001] The invention relates to a sewing machine, in particular to a 3D mesh sewing machine. Background technique [0002] In the production of existing 3D mesh mattress cores, chemical adhesives are generally used to bond several 3D mesh fabrics that are stacked in sequence. First, cut the 3D mesh into 3D mesh pieces of the size required for the 3D mesh mattress core, and then apply the chemical adhesive to the 3D mesh. After repeating the process, apply chemical adhesive to several pieces. The 3D mesh pieces of the agent are overlapped in turn to form a 3D mesh square. Because the use of chemical adhesives requires a period of air-drying, it takes a long time to make. [0003] At present, there is no sewing machine that directly sews several pieces of 3D mesh, and forms several pieces of 3D mesh at one time through a single needle and single thread, and sews them together. Moreover, the mattress core made of chemical adhesive cannot be folded or washed. ...

AI Technical Summary

Problems solved by technology

[0004] The present invention provides a 3D mesh sewing machine, the main purpose of which is to overcome the drawbacks of the existing 3D mesh mattress cores, where the sequentially overlapping 3D mesh is bonded with a chemical adhesive, and the chemical adhesive contains formaldehyde , causing harm to the human body

Moreover, the production efficiency is low, and the operation is inconvenient, etc.
