Problems solved by technology

[0002] As a textile tool, the Jacquard machine can only weave fabrics with complex patterns. In the three-dimensional loom, the Jacquard machine is used in conjunction with the weft insertion mechanism. The openings of the existing Jacquard machine transmission mechanisms are all Continuous action, resulting in the movement of the rapier into and out of the sword is not stable enough, the sley does not have enough rest time at the rear, it is difficult to ensure that the weft insertion device passes through the shed smoothly, and it is difficult to tighten the weft yarn

Abstract

The invention discloses a transmission mechanism of a cam shedding jacquard. The transmission mechanism comprises a first rotating shaft and a second rotating shaft, wherein a first cam and a second cam are respectively in key connection to the middle of an outer wall of the first rotating shaft from back to front, a swinging piece sleeves the middle of an outer wall of the second rotating shaft,an idler wheel is in shaft connection to the inner side of a lug plate of the swinging piece, and flanges are connected to the front sides and the rear sides of the outer walls of the first rotating shaft and the second rotating shaft in a sleeving mode. The transmission mechanism of the cam shedding jacquard can provide sufficient standing time for a batten in the rear, so that stable rapier feeding and rapier returning movements of a rapier is ensured, the situation that a weft guider smoothly passes through a shed is ensured, and weft yarns tightening is facilitated.

Description

technical field [0001] The invention relates to the technical field of jacquard machines, in particular to a transmission mechanism of a cam opening jacquard machine. Background technique [0002] As a textile tool, the Jacquard machine can only weave fabrics with complex patterns. In the three-dimensional loom, the Jacquard machine is used in conjunction with the weft insertion mechanism. The openings of the existing Jacquard machine transmission mechanisms are all Continuous action causes the movement of the rapier to move in and out of the sword is not stable enough, the sley does not have enough rest time at the rear, it is difficult to ensure that the weft inserter passes through the shed smoothly, and it is difficult to tighten the weft yarn. Contents of the invention [0003] The object of the present invention is to provide a transmission mechanism of a cam shedding jacquard machine to solve the problems raised in the above-mentioned background technology. [0004...
