Description

Double-cam needle lifting mechanism of electronic jacquard

Technical Field

The utility model belongs to the technical field of jacquard equipment, and particularly relates to a double-cam needle lifting mechanism of an electronic jacquard.

Background

In the textile sector, fabrics are usually woven from warp and weft yarns. On a loom, the warp is divided into an upper layer and a lower layer alternately according to a certain rule, so that a channel for the weft to pass through is formed, namely, a warp opening is formed, after the weft is introduced into the opening, the two layers of warp alternate up and down according to a fabric organization method, a new warp opening is formed, and the weaving process of the fabric is completed repeatedly. The formation of the warp openings is completed by a warp opening selection mechanism, and is the most core step in the textile technology.

The existing shedding mechanism generally utilizes complex combinations of a plurality of groups of levers, conjugate cams and connecting rods to realize up-and-down movement of the inner needle lifting arm and the outer needle lifting arm, the transmission mechanism is too complex in structure, when the transmission mechanism moves up-and-down, the cams and the cutter lifting system can generate larger impact, so that the noise is larger in the running process of the equipment, and the service life of the equipment can be further shortened due to the impact.
