Problems solved by technology

[0004] However, there are still many deficiencies in this electronic jacquard knife lifting mechanism. Two pairs of gear sets and a sprocket set 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 and affect Transmission stability and machining accuracy

Abstract

The invention provides a swinging mechanism in a jacquard, and belongs to the technical field of textile machines. The problem that in an existing jacquard, transmission is instable, so that the quality of jacquard fabric is affected is solved. The jacquard comprises a rack, a left supporting plate and a right supporting plate, and the swinging mechanism comprises a transmission shaft, a left eccentric wheel and a right eccentric wheel. The left eccentric wheel is fixed to one end of the transmission shaft, a left rocking rod is arranged on the left eccentric wheel, a first connecting rod is arranged at one end of the left rocking rod, and a second connecting rod is arranged at the other end of the left rocking rod. The right eccentric wheel is fixed to the other end of the transmission shaft, the eccentric potential difference between the left eccentric wheel and the right eccentric wheel is 180 degrees, a right rocking rod is arranged on the right eccentric wheel in a sliding mode, a third connecting rod is arranged at one end of the right rocking rod, a fourth connecting rod is arranged at the other end of the right rocking rod, and a driving structure is further arranged on the transmission shaft and can drive the transmission shaft to rotate. Upper jacquard needles and lower jacquard needles achieve interweaving, so that the jacquard fabric is obtained through weaving, and the transmission property is stable.

Description

technical field [0001] The invention belongs to the technical field of textile machinery, and relates to a jacquard machine, in particular to a swing mechanism for a handle in the jacquard machine. 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. However, the transmission structure for controlling the up and down motion of the lifting knife is often more complicated, and meanwhile, it is not convenient for the maintenance and maintenance of the jacquard machine. [0003] Due to th...
