Shedding device, shedding device assembly and jacquard

Abstract

The invention discloses a shedding device, which comprises an inner plate and at least a wire hook capable of moving up and down, wherein the upper end of the inner plate is installed with an electromagnet, at least one pivot is arranged on the inner plate, and the pivot is located at one side of the electromagnet; the upper end of the wire hook is provided with a first hook extending back to the electromagnet, which is characterized in that the wire hook also comprises a pendulum hook, the amount of the pendulum hook is equal to that of the wire hook, and each pendulum hook is matched with each wire hook; the upper end of the pendulum hook is sleeved on the pivot and rotates around the pivot, and the lower end of the pendulum hook can fix the wire hook and enable the wire hook not to move downward; after the electromagnet is energized and has magnetism, the lower end of the pendulum hook can be attracted by the electromagnet and moves toward the electromagnet; and a first elastic resetting device can move toward the electromagnet along with the lower end of the pendulum hook and generate elastic force, and the elastic force can enable the lower end of the pendulum hook to reset to the location before movement. The shedding device of the invention reduces the power and energy consumption of the electromagnet, improves the efficiency of the electromagnet, and the production and installation of the shedding device become much easier.

Description

technical field [0001] The invention relates to an opening device, an opening device assembly and a jacquard machine. Background technique [0002] Fabrics are usually woven from warp and weft threads. On the loom, in order to realize the interweaving of warp and weft yarns, the warp yarns must be divided into upper and lower layers according to certain rules to form a passage for the weft yarns to pass through, that is, the shed. Alternate positions up and down to form a new shed, and the weft thread passes through the shed again. This repeated movement is called shedding movement, or shedding for short. The opening movement is accomplished by the opening mechanism. The shedding mechanism has two functions, one is to make the heald frame (or heddle) move up and down to separate the full-width warp yarns to form a shed; the other function is to control the lifting sequence of the heald frame according to the interweaving law required by the fabric structure .
