Swing cam resetting separable jacquard needle selecting device

Abstract

The invention refers to an electronic jacquard mechanism which is a swing cam resetting separable jacquard loom needle selecting device, including a case shell with upper shell body and lower shell body, a jacquard hook, a jacquard bottom coupling lifting knives and a jacquard rope, the upper shell inside has two electromagnets which has a coil, one side of the each electromagnet has a electromagnet hook which is fixed at the upper shell body by a pivot and the head of which is contact with the spring, the upper shell inside also have a independent swing cam, the hook of electromagnet hook can be strutted or reset; the upper shell body and the lower shell body can be removable, the inside of lower shell body has a jacquard hook and a jacquard bottom coupling lifting knives which are contact, the jacquard rope is connected with the jacquard hook. The structure of invention is simple, the volume is small, realizing one jacquard to one weave, and the jacquard hook is not easy to abrasion and distortion.

Description

technical field [0001] The invention relates to an electronic jacquard device for wide cloth, in particular to a needle selection device for a jacquard machine. Background technique [0002] The existing electronic jacquard needle selection device mostly uses the French Staubli device, that is, the fixed electromagnet controls the fixed iron hook to perform double selection and hanging vertical needles, and the double springs return to reset, and the jacquard is driven by double handles. The hook squeezes the iron hook so that the iron hook is in zero-distance contact with the electromagnet. The movement of the lifting knife is controlled by the conjugated cam, through the adjustment of the connecting rod between the conjugated cam and the lifting box, the parallel opening of the warp can be obtained, and the heald is returned by the elastic body. Its disadvantages are: there is friction between the iron hook and the jacquard hook, and the jacquard hook is easy to wear and ...

AI Technical Summary

Problems solved by technology

Its disadvantages are: there is friction between the iron hook and the jacquard hook, and the jacquard hook is easy to wear and deform; and the rotating structure of the double lifting mechanism with different directions is complicated, the volume is large and the lifting range is large, and the mechanical reset and heald resistance are also large. , due to the huge structure of the needle selection device, it is impossible to realize the jacquard of 1 lift 1 on the wide-width loom
