Problems solved by technology

[0002] Sewing machines usually use the bobbin thread and upper thread to complete the fabric sewing, and the bobbin thread is provided by the bobbin with the bobbin thread wound in the shuttle. During the specific sewing process, the bobbin will have a temporary lack of thread. Thread operation, if the entire bobbin is replaced, it is too wasteful, but manual winding is too cumbersome, time-consuming and labor-intensive, so it is improved to use the motor transmission mechanism of the sewing machine to complete the automatic winding operation
The winding mechanism of the existing sewing machine has a complex structure, large volume, and unreasonable design. It is placed outside the casing, which not only affects the aesthetics of the sewing machine, but also interferes with the production process, affecting the working efficiency and stability of the sewing machine. , that is, the high failure rate
In addition, the existing sewing machine winding mechanism requires manual observation of the winding situation at any time during the winding process to prevent the winding from being too full, resulting in low automation and low work efficiency

Abstract

The invention discloses a built-in sewing machine winding mechanism. The sewing machine includes a casing and a motor transmission mechanism arranged in the casing. The sewing machine winding mechanism is built in the casing and can fix the bobbin and complete automatic winding of the bobbin. The operation includes a bracket, a swingable connecting rod, a bevel gear mechanism linked with the motor transmission mechanism, a winding shaft mechanism that can rotate with the rotation of the bevel gear mechanism, and a fork mechanism. A rotating annular rubber ring, a winding shaft that can rotate with the rotation of the annular rubber ring, the bobbin is fixed on the winding shaft and can rotate with the rotation of the annular rubber ring so as to be able to wind. The present invention uses the clutch state between the annular rubber ring and the bevel gear to complete the automatic winding operation of the bobbin. The winding mechanism of the sewing machine is built in the casing, and has the advantages of reasonable structural design, high degree of automation, and good working stability.

Description

technical field [0001] The invention relates to the technical field of machinery, in particular to a built-in sewing machine winding mechanism. Background technique [0002] Sewing machines usually use the bobbin thread and upper thread to complete the fabric sewing, and the bobbin thread is provided by the bobbin with the bobbin thread wound in the shuttle. During the specific sewing process, the bobbin will have a temporary lack of thread. Thread operation, if the whole bobbin is replaced, it is too wasteful, but winding by hand is too cumbersome, time-consuming and labor-intensive, so it is improved to complete the automatic winding operation by means of the motor transmission mechanism of the sewing machine. The winding mechanism of the existing sewing machine has a complex structure, large volume, and unreasonable design. It is placed outside the casing, which not only affects the aesthetics of the sewing machine, but also interferes with the production process, affecti...
