Sewing machine with thread hooking and clamping unit

Abstract

The invention discloses a sewing machine with a thread hooking and clamping unit, comprising an operating table, a body (1), a needle rod (2) and a needle (3). The body (1) is disposed on the operating table. The needle rod (2) is disposed on a nose (1.1) of the body (1). The needle (3) is disposed at the lower end of the needle rod (2). The thread hooking and clamping unit is disposed on the body (1) and comprises an electromagnetic driver, a linkage, a thread hooking mechanism, a thread clamping mechanism and a support (4). The support (4) is mounted on the nose (1.1). The linkage and the thread clamping mechanism are both mounted on the support (4). The thread hooking mechanism is connected to the linkage. The electromagnetic driver is mounted on the body (1) and connected with the linkage. Both the thread hooking mechanism and the thread clamping mechanism are disposed on one side of the needle (3). The sewing machine is simple in structure, has few parts, allows the needle position to be conveniently adjusted and is stable to use.

Description

technical field [0001] The invention relates to the field of sewing machines, in particular to a sewing machine with a hook thread clamping device. Background technique [0002] 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 fabrics such as cotton, fiber crops, silk, wool, and artificial fibers, and products such as leather, plastics, and paper. [0003] The sewing machine includes an operating table, a body, a needle bar and a bur; the body is arranged on the operating table; the needle bar is arranged on the head of the body; the bur is arranged on the The lower end of the needle bar described above. In order to be more convenient to use, current sewing machines will install a thread clamping device on the body of the sewing machine. The thread clamping device is used to hook back the cut thread end and properly ti...

AI Technical Summary

Problems solved by technology

However, the hook thread clamping device of the existing sewing machine has many parts, complex structure, and many connection points between parts. The gap between parts and parts will become larger after long-term use, causing the position of the hook thread clamping device to become larger. Offset occurs, causing errors in the hooking action, missing hooking lines or unstable clamping of the sliding line, etc.
