AI Technical Summary
The short peak time of the opening trajectory curve of the eccentric wheel structure in existing jacquard machines causes the shuttle to easily rub against the warp yarn, resulting in malfunctions and affecting the speed increase of the loom.
By adopting a conjugate cam design, the peak curve time of the opening trajectory curve is extended. Through the conjugate relationship between the first and second cams, the stable reciprocating motion of the knife lifting frame is achieved, reducing mechanical parts and lowering weight and energy consumption.
It extends the time for the shuttle to enter and exit the shed, avoids friction on the warp yarns, improves weaving efficiency, and enables high-speed weaving.
