Basic Structure


The 8-hole knife of the ribbon weaving machine is a crucial component of the machine. It is usually long and strip-shaped, with 8 precisely designed holes. These holes are used to connect other components of the ribbon weaving machine, such as connecting rods and drive shafts. The diameter of the holes is generally between a few millimeters and a dozen or so millimeters, and the specific size depends on the model and design requirements of the ribbon weaving machine. The overall shape of the knife is conducive to its role in the mechanical transmission system of the ribbon weaving machine. It may be more than ten centimeters to dozens of centimeters long and is mostly made of metal, such as high-quality steel, to ensure its strength and durability.

Working Principle


During the operation of the ribbon weaving machine, the 8-hole knife plays roles of transmission and control. It is indirectly connected to the power source (such as an electric motor) through a series of mechanical connections. When the power source drives the ribbon weaving machine to operate, the 8-hole knife will swing or move back and forth along with the movement of the transmission system. For example, it is connected to the power shaft through a connecting rod, and the rotational motion of the power shaft can be converted into the reciprocating motion of the knife. The frequency and amplitude of this reciprocating motion are closely related to the weaving speed and pattern formation of the ribbon. The 8 holes of the knife can precisely control the movement trajectories of different connected components, thereby ensuring that the warp and weft threads of the ribbon can be interwoven in a predetermined manner during the weaving process.
