Abstract
The invention relates to an eccentric transmission mechanism of a high-speed multi-guide-bar jacquard-weave warp knitting machine. In the high-speed multi-guide-bar jacquard-weave warp knitting machine, a looping process results from an interaction of a groove pin, a pin core, a knocking over piece and a sinking piece. The sinking piece is fixed, the groove pin, the pin core and the knitting over piece move according to respective needed working track respectively, and then the looping process is completed. The eccentric transmission mechanism of the high-speed multi-guide-bar jacquard-weave warp knitting machine comprises a pin core connecting rod mechanism, a groove pin connecting rod mechanism and a knitting over piece connecting rod mechanism. Each of the pin core connecting rod mechanism, the groove pin connecting rod mechanism and the knitting over piece connecting rod mechanism is composed of an eccentric device, an eccentric connecting rod, a connecting rod, an oscillating rod, an ejector and the like. The components are all arranged on a connecting rod frame in an oil tank, and are connected with one another through bearings and fixing shafts. The eccentric devices are mounted on a spindle, and a spindle motor drives the spindle to rotate. Each eccentric device drives the corresponding connecting rod mechanism to move. Finally, the groove pin, the pin core and the knitting over piece move according to expected laws.
Description
Technical field
