Problems solved by technology

[0005] The head of a 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 of 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

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

[0001] Technical field: [0002] The invention relates to the technical field of sewing machines, in particular to a high-speed sewing machine with a raised head that is convenient for feeding materials and has high sewing efficiency. [0003] Background technique: [0004] At present, sewing machine is to use one or more sewing threads to form one or more stitches on the sewing material, so that one or more layers of sewing material are interwoven or sewed up. The sewing machine can sew fabrics such as cotton, fiber crops, silk, wool, and artificial fibers, and products such as leather, plastics, and paper. [0005] 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 he...
