What are the advantages and disadvantages of the rotary shuttle and the shuttle? Why some machines to design hook., such as a flat head keyhole machine, high-speed sewing machine and so on, and some machines to design a swing shuttle, such as sets of node machine, 1903 nail fastening machine, old-fashioned household machine. If a set of machine, 1903 pin buckle machine, old-fashioned family machine design into a spiral is not better?

Swing shuttle has the advantages of simple structure, low cost but by inertial force, will cause the shuttle bed rail pendulum shuttle support at both ends and a swing shuttle wear only for household sewing machines and a low speed sewing machine. Rotation of the shuttle can rotate speed, stable operation, low noise, suitable for high-speed sewing machine. The following describes the working principle and the structure of the spindle of a spin classification, in order to understand more about.

In sewing equipment, the sewing machine, which is the most common, is the most common in the sewing machine. The sewing machine most is the rotating shuttle, with its shuttle tip hook line ring, while expanding ring line and guide line ring around the bobbin and a lock stitch. Here is a brief introduction to the work principle of the ordinary rotary shuttle.

In the machine needle to the lowest point up a certain distance, rotating shuttle bed shuttle tip to hook into the loop line and shuttle tip hook line ring to rotate. When the circle line was sent to the rotating shuttle frame rails, wire ring is the shuttle frame junction hook hook, hook rack junction hook should be online ring soon close, so that the line ring end left

Time to move to guide back to, the junction hook machine needle with the movement axis angle is about 50 degrees, by the shuttle bed shuttle tip outer convex above 45 degrees hook line ring, continues to rotate, wire ring at the end of the hook on the junction hook, in order to make the line ring slides smoothly to the surface of the shuttle frame and the hypotenuse of the tail of the wiring board to wire loop of thread to externally oriented poke, and posterior part of the ring line side shuttle frame junction hook hook, slide to the bottom of the shuttle frame. In this moment, machine needle exit hook. Ring ring frame line outward convex ring to slide out of the bottom of the frame of the shuttle frame line is very smooth, the wire ring smoothly from the shuttle, the shuttle tip rotates 180 DEG, take-up rod rises, the take-up lever of sent down the remaining part of the line up, a shuttle tip hooked wire loop continues to rotate, the line in the first half part of the wire plate below, by the outer frame 45 degree inclined, moving the wire plate edge, and gradually a shuttle frame, the first half of the wire rings aside. The latter part of the ring was composed of spindle junction hook hook, and the line ring before and after separately, the last line of the front and back cover of the shuttle frame, the bottom line in the middle, the take-up of the tensioning rod line, the formation of stitch.
