Double-crank jacquard machine opening mechanism with adjustable opening height

Abstract

The invention discloses a double-crank jacquard machine opening mechanism with adjustable opening height. The double-crank jacquard machine opening mechanism comprises a driving shaft and an optical shaft arranged in parallel, wherein one end of the driving shaft is hinged with a first crank and a second crank sequentially; a difference of phases of the first crank and the second crank is 180 degrees; one end of the first crank and one end of the second crank, which are away from the driving shaft, are hinged with two groups of first connecting rods arranged in parallel; the other ends of the two groups of first connecting rods are hinged with two groups of second connecting rods; the optical shaft is sequentially hinged with two groups of driving plates in the length direction; hinge lugs hinged with the second connecting rods are mounted on sides, close to the driving shaft, of the two groups of driving plates; long-strip-shaped sliding chutes are formed in sides, away from the optical shaft, of the hinge lugs in the length direction of the driving plates; two groups of guide rails are mounted on inner walls at bottoms of the sliding chutes in the length direction. The double-crank jacquard machine opening mechanism provided by the invention is convenient and rapid in adjustment and stable in structure, can reflect, detect and adjust the size of the current opening timely, and can meet requirements of different fabric materials.

Description

technical field [0001] The invention relates to the technical field of shedding mechanisms, in particular to a jacquard shedding mechanism with a double crank adjustable shedding height. Background technique [0002] As an important textile machine, the Jacquard machine is widely used in the weaving of various cloth materials. Due to the different properties of the materials, the opening size of the Jacquard machine is required to be different. The opening size of the traditional Jacquard machine is fixed. Although the existing The jacquard machine has the function of adjusting the opening size. Due to the different properties of various cloth materials, the opening size of the jacquard machine is required to be different. The traditional jacquard machine is not accurate in adjusting the opening size, and it is difficult to adapt to the requirements of different cloth materials. Adjusting the controls is a hassle.
