Problems solved by technology

[0003] However, the thread wound on the bobbin tends to loosen due to vibration and rotation, and becomes entangled with other threads, making the work complicated and wasteful such as cutting and discarding the entangled thread.
At present, many sewing machines often have thread jamming under the condition of high-speed operation.

Abstract

The invention discloses a thread disorder prevention cop latch of a sewing machine. The cop latch comprises a cop latch body, a bottom thread cop latch shell, a cop latch shell and a bottom thread cop latch body. The cop latch body is provided with a thread outlet side seam, a hook piece, a fixing screw, a positioning sleeve, a semi-circular hole, a bottom thread cop latch rail, a bottom thread cop latch shell, a positioning sleeve hole, a thread sliding groove, a thread inlet opening, a bayonet, a side wall round hole, a bottom thread cop latch installation shaft, a thread clamping adjusting ring, a positioning sleeve buckle, the bottom thread cop latch body, a cop latch thread outlet groove and the cop latch shell. The cop latch is reasonable in design, reduces the work intensity for replacing a cop latch of the sewing machine, improves the work efficiency of the sewing machine and guarantees the quality of products processed through the sewing machine, and the phenomenon of bottom thread cop latch thread jamming is not likely to happen in the use process.

Description

technical field [0001] The invention relates to the technical field of sewing machines, in particular to a sewing machine tamper-proof bobbin. Background technique [0002] Generally speaking, bobbins are used in sewing operations performed with home sewing machines. Sewing machine users usually make the upper thread and lower thread the same color when using the sewing machine. Therefore, generally speaking, the user keeps a plurality of bobbins wound with frequently used thread for each thread color, and adjusts them according to the thread color of the upper thread. Replace the entire bobbin. [0003] However, the thread wound on the bobbin tends to loosen due to vibration and rotation, and becomes entangled with other threads, making the work complicated and wasteful such as cutting and discarding the entangled thread. At present, many sewing machines often have thread jams when they are operating at high speed. Contents of the invention [0004] The purpose of the ...
