Sewing machine shuttle core usage
The shuttle core of a sewing machine is an important component, mainly used to guide thread from the spool to the needle hole and complete a round trip movement of the needle. It is located inside the shuttle shell and is wound with a coil for storing wire. When the sewing machine is in operation, the shuttle core will move back and forth on the track of the shuttle bed, conveying the coil to the needle hole and interweaving it with the surface thread to form a locking buckle, completing the sewing process 2. The function of the shuttle core is to shuttle the thread back to the bottom under the fabric, forming a sewing thread. The shuttle core on old-fashioned sewing machines is a vulnerable part that needs to be replaced frequently to ensure the normal use of the sewing machine.
The principle of rotary shuttle is basically the same as that of shuttle, but the process and method of forming thread marks are different from those of shuttle. Spinning shuttle rotates at equal angular velocity, while swinging shuttle oscillates back and forth at different speeds. During one reciprocating motion of the needle (one rotation of the spindle), the rotary shuttle rotates twice at equal angular velocity, while the oscillating shuttle swings back and forth once. The rotary shuttle is fixed by the rotary shuttle frame, while the rotary shuttle bed is rotating. It is hooked by the tip of the shuttle bed to form a thread loop, and the hook of the rotary shuttle frame is used to separate the thread, allowing it to pass around the shuttle core sleeve and the bottom and top of the shuttle frame, and detach from the head of the rotary shuttle plate to form a thread loop. The working principle of a rotary shuttle is usually that after the needle rises a certain distance, the shuttle tip of the rotary shuttle bed begins to hook into the wire loop. The shuttle tip hooks onto the wire loop and continues to rotate. When the wire loop is sent to the guide rail of the rotary shuttle frame, it is hooked by the wire splitting hook of the shuttle frame. At this time, the needle should rise by about 2 millimeters from the lower limit position.
