High-speed sewing machine capable of raising machine head

Abstract

The invention discloses a high-speed sewing machine capable of raising a machine head. The machine comprises a base, and the machine head which is mounted on the base; the base is fixedly mounted on a stand; a rotating shuttle main shaft for driving a rotating shuttle is mounted on the base; a driving shaft for driving the rotating shuttle main shaft is mounted on the machine head, wherein the machine head is pivoted to the base; a cylinder device for raising the machine head is mounted below the stand; a derailing device for preventing the driving shaft and the rotating shuttle main shaft from derailing is arranged on the base. According to the machine, the cylinder device can control the machine head to raise to discharge materials conveniently, and thus the discharging time is reduced, and the production efficiency is increased; in addition, the driving shaft and the rotating shuttle main shaft can be prevented from derailing through the derailing device; therefore, the machine is flexible to operate, and stable in working efficiency; a positioning device mounted at the back of a connecting block in the cylinder device is able to position the cylinder device, so that the safety working coefficients can be increased.

Description

Technical field: [0001] The invention relates to the technical field of sewing machines, in particular to a high-speed sewing machine capable of raising the head which is convenient for feeding materials and has extremely high sewing efficiency. Background technique: [0002] At present, a sewing machine is a machine that uses one or more sewing threads to form one or more stitches on the sewing material to interweave or sew one or more layers of sewing material. The sewing machine can sew cotton, linen, silk, wool, man-made fibers and other fabrics and leather, plastic, paper and other products. The stitches sewn are neat and beautiful, flat and firm, and the sewing speed is fast and easy to use. [0003] The heads of traditional sewing machines are basically fixed on the machine base, and the height between the needle installed on the machine head and the rotary hook and the feed plate installed on the machine base is the same and is not adjustable. This kind of sewing machine ca...

AI Technical Summary

Problems solved by technology

[0003] The head of the traditional sewing machine is basically fixed on the machine base. The height between the needle installed on the machine head, the rotary hook installed on the machine base and the feeding plate is the same, and it is not adjustable. This kind of sewing machine can only It is very clumsy to use for sewing products with a certain height; for the height of the product to be placed is slightly lower than the height between the needle, the hook and the feeding plate, it can barely be used for sewing operations, but the sewing operation will greatly increase The sewing operation time is reduced, and the production efficiency is extremely reduced

In addition, for thicker products, that is, higher than the height between the needle, the hook and the feeding plate, the traditional sewing machine is helpless, causing great trouble to the user
