Vibration type thick material sealing and sewing device

Abstract

The invention provides a vibration type thick material sealing and sewing device which comprises a vibration shell, wherein the vibration shell is assembled at the lower part of a sewing machine head; a vertical sliding cavity is designed inside the vibration shell; a sliding block which can slide up and down is assembled inside the sliding cavity; the bottom of the sliding block is connected with the lower part of the sliding cavity through a spring; a sewing needle which vertically extends outside the vibration shell is connected to the lower part of the sliding block; a lower magnet of which the magnetic line of force faces vertically is mounted at the upper part of the sliding block; a vibration wheel which can rotate along a horizontal shaft is assembled at the upper part of the sliding block; and upper magnets are uniformly distributed on an annular loop of the vibration wheel. When the vibration type thick material sealing and sewing device is used, the vibration shell moves downwards as a whole along the sewing machine head, and the sewing needle can puncture a fabric to be sewn in an up-down rapid vibration manner, so that multiple times of puncture action can be completed in the process that the sewing machine head moves downwards once, a relatively thick fabric can be relatively smoothly punctured, and the whole sewing process can be smoothly completed.

Description

Technical field [0001] The invention belongs to the technical field of garment sewing, and in particular relates to a vibration type thick material sealing sewing device. Background technique [0002] Clothes are usually stitched from multiple pieces of independent fabrics. In ancient times, clothes were sewn by hand with needles and threads. In the current garment-making process, the sewing process in clothes is mostly done by sewing machines. When the sewing machine sews the fabric, two sets of sewing threads are designed on the upper and lower parts of the fabric respectively. When working, the sewing threads of the upper group penetrate the lower part of the fabric to be stitched through the needle, and a rotary hook structure is designed on the lower part of the fabric. The interior is equipped with the sewing thread of the next group, and the outer edge of the hook is designed with a hook structure, and the hook can rotate around the middle axis at the same time. The ...

AI Technical Summary

Problems solved by technology

Traditional fabrics are usually relatively light and thin, and can be easily pierced by needles to complete the knotting process. However, in some thick fabrics, or some hard leather sewing processing, and some thick cloth sole processing, the traditional sewing machine It is difficult for needles to pierce these thick materials for knotting

In the traditional sewing machine, every time the sewing head moves down, the piercing action is only completed once, but for some thicker materials, it is difficult to pierce the material at one time. At the same time, in the traditional processing, in order to make the piercing action of the needle Easier to do, usually with thinner needles, which makes them easier to break

Many thicker fabrics like many leathers are required to have a waterproof function, and when stitching, it is often easier to seep water at the stitching position, which affects the final use effect of the clothes
