Understand the distinction between spiral shuttle and pendulum shuttle
The shuttle is a shuttle tip hook the wire ring, expanding the wire ring, and guiding the wire ring to bypass the spindle center to form a lock line track. The shuttle can rotate at equal speed, smooth operation, small noise, suitable for high-speed sewing machine. The structure of the shuttle is simple, the cost is low, but there is an inertial force, which will cause the wear of the shuttle bed and the shuttle itself, which is generally applicable to the low-speed sewing machine. Spinshuttle can rotate at average speed, smooth operation, small noise, suitable for high-speed sewing machine. Spinshuttle and swing shuttle are composed of shuttle bed, shuttle skin, shuttle plate, shuttle frame.
The principle of the formation of the spindle is basically the same as that of the shuttle, but the process and method of the formation are different from that of the shuttle: the shuttle is the equal angular rotation movement, while the shuttle is the unequal reciprocating movement; in the needle movement, the rotation of the shuttle rotates for two weeks, but the shuttle only swings back and forth once. In the shuttle, the shuttle frame is fixed, the shuttle bed is rotated, the shuttle bed tip and the hook of the wire, so that it can bypass the spindle heart sleeve and the bottom and top of the shuttle frame, from the head of the shuttle board to form the wire ring.
