Swing mechanism of rocker

Abstract

The invention provides a swing mechanism of a rocker, belonging to the technical field of textile machinery and solving the problems that the swing mechanism in the prior art is complicated, and poor in stability. The swing mechanism of the rocker comprises an operating platform and a supporting plate, wherein a driving shaft is arranged on the supporting plate, an eccentric wheel is fixedly arranged on one end of the driving shaft, a rotating shaft is also arranged on the supporting plate by adopting a manner of axial fixing and circumferential rotation, the rotating shaft is positioned obliquely above the driving shaft, the rocker is fixedly arranged on one end of the rotating shaft, the rocker and the eccentric wheel are positioned in the same one side of the supporting plate, a roller is arranged on one end of the rocker in a rotating manner, a groove is formed in the eccentric wheel along the arc-shaped direction, the roller is arranged in the groove, and a rotating structure capable of driving the driving shaft to rotate is also arranged on the operating platform. The swing mechanism of the rocker has the advantages of being capable of reducing the driving friction and transferring large power.

Description

technical field [0001] The invention belongs to the technical field of textile machinery, and relates to a rocker in a jacquard machine, in particular to a rocker swing mechanism. Background technique [0002] As a textile tool, the Jacquard machine is the representative of the highest achievement of ancient Chinese weaving technology. With the continuous improvement of the production level, the Jacquard machine has also been further improved and perfected since the Western Han Dynasty. In the existing jacquard machine, its main feature is to control each warp thread with heald thread instead of heald frame, which can make each warp thread move up and down independently, and can be used for weaving complex pattern weaves. [0003] At present, the structure for controlling the up and down swing of the lifting knife is often complicated. Gear sets or sprocket sets are generally used to drive the lifting knife to move up and down, resulting in a large load on the entire structu...

Problems solved by technology

[0003] At present, the structure for controlling the up and down swing of the lifting knife is often complicated. Gear sets or sprocket sets are generally used to drive the lifting knife to move up and down, resulting in a large load on the entire structure, and the gear teeth are easy to wear, which affects the stability of the transmission. and machining accuracy
