Three opening device of rotary electronic dobby

Abstract

The invention provides a three-shed device of a rotary electronic dobby and belongs to the technical field of textile machinery. The rotary electronic dobby comprises a tank body, a heald lifting arm driving mechanism and a heald lifting arm mechanism, wherein the heald lifting arm driving mechanism is arranged in a tank body cavity of the tank body through a spindle; the heald lifting arm mechanism is arranged in the position, corresponding to the left side of the heald lifting arm driving mechanism, in the tank body cavity of the tank body through a heald lifting arm shaft and is connected with the heald lifting arm driving mechanism. The three-shed device comprises a pair of supporting seats, a swing arm mechanism and a heald frame three-shed heald lifting blade mechanism, wherein the supporting seats correspond to each other and are fixed with one side, opposite to the tank body cavity of the tank body, of the left tank wall when in a state perpendicular to the left tank wall of the tank body; the swing arm mechanism is supported between the pair of supporting seats and is connected with the heald lifting arm mechanism; the heald frame three-shed heald lifting blade mechanism is connected with the swing arm mechanism. The three-shed device of the rotary electronic dobby has the following advantages: resources are saved, and the requirement for three sheds of a loom for weaving pile warp fabric is met; the integral structure is concise, and the rotary electronic dobby in the prior art can be subjected to addition improvement, so that economic cheapness can be reflected.

Description

technical field [0001] The invention belongs to the technical field of textile machinery, and in particular relates to a three-opening device of a rotary electronic dobby, which is used to form a weaving shed opening of a heald frame required for double-layer weaving of a loom. Background technique [0002] The aforementioned rotary electronic dobby is referred to as "dobby" for short. As a high-speed and energy-saving shedding mechanism, it is used to drive the heald frame of the loom to lift up and down to ensure the weaving action of the loom. The mainstream mechanism matched with the shuttleless loom. [0003] Since the common dobby can only realize two positions of the upper opening and the lower opening, it can only form a single weaving shed of the loom, and the fabric woven by the loom is a common single-layer fabric. For weaving high-grade and widely used double-layer pile warp fabrics, the common practice in the industry is to use the double-layer cut pile method....

AI Technical Summary

Problems solved by technology

At present, the three-shed (i.e. three shed) device of the three-shed dobby is usually manufactured by a professional manufacturer as a special model and supplied to the textile manufacturer after being matched with the loom produced by the loom manufacturer. The shortcoming lies in: the price Expensive, complex structure, and small scope of application (that is, the audience), which restricts the development of three-slit velvet looms
