Description

A kind of three-dimensional shedding device of weaving machine

Technical field

The present invention relates to a kind of three-dimensional shedding device of weaving machine, belong to textile technology field.

Background technology

The three-dimensional woven technology is a kind of fabric technology; It makes fiber in three dimensions, distribute and be interweaved along a plurality of directions and forms not stratified overall structure together; Have plurality of advantages such as light weight, intensity height, good mechanical performance by it as the composite product that strengthens system one-tenth; Oneself warp is widely used in various fields such as Aero-Space, defence and military, communications and transportation, the energy at present, and constantly expands to civil area.

The weaving technology difficulty of three-dimensional woven fabric is big, and existing three dimensional fabric loom cost is high, efficient is low, and the interlayer conjugation is not high, can not satisfy the needs of multiple structure.The three-dimensional loom many places of present domestic development are in manual or half machine performance; Or be in the laboratory model machine stage, and the kind of the three dimensional fabric of institute's weaving is few, and quality stability is difficult to guarantee; Realize the mechanization production of three-dimensional woven fabric, must research and develop the three-dimensional loom of high efficiency, automation.

As shown in Figure 1, be the basic weaving principle figure of traditional three-dimensional Rapier looms.In weaving process, warp thread passes the heald eye of the simple eye heald 12 on the heald frame 2 according to certain rules by drawing on the creel 7, pass reed 8 again after, by 10 clampings of fabric anchor clamps; Shedding mechanism control heald frame 2 goes up and down, and makes warp thread form a plurality of shed opens; Wefting insertion sword 9 clipped weft yarns pass shed open; After wefting insertion sword 9 withdrawed from, reed 8 was pushed weft yarn to fell; Motor 11 drives anchor clamps 10 stereo fabric that weaves is deflected from fell, thereby accomplishes a wefting insertion circulation.

Shedding mechanism is the most key mechanism of 3 D stereo loom.See theoretically, the thicker of stereo fabric, the warp thread number of plies in vertical direction is just many more.The warp thread number of plies is many more, and the number of pages of required heald frame is just many, and the opening amplitude of warp thread (yarn particularly hangs down) is also big, and the shed open distortion increases greatly, and the definition of shed open reduces; The arranging density of warp thread is also high more, and between warp thread and the warp thread and warp thread and heald wearing and tearing aggravation, the frequent broken end that these problems both may cause warp thread brings difficulty to wefting insertion again.

Summary of the invention

The purpose of this invention is to provide a kind of wearing and tearing that can reduce heald, avoid the three-dimensional shedding device of weaving machine of the frequent broken end of warp thread warp thread.

In order to achieve the above object, the invention provides a kind of three-dimensional shedding device of weaving machine, comprise heald frame, it is characterized in that, a slice heald frame connects many monofilaments at least.

Preferably, a slice heald frame connects push rod at least, and push rod connects servo electric jar, and servo electric jar connects driver, and driver connects computer.

The present invention uses the open loop system of electrical servo cylinder control 3 D stereo loom, and promptly every suit servo electric jar is controlled a slice heald frame respectively, and the motion amplitude of every heald frame can change arbitrarily; Cooperate many monofilaments of installing on the heald frame; Every opening once can form a plurality of shed opens of any setting, has greatly enriched the woven institutional framework of possibility, can significantly reduce the number of pages of required heald frame simultaneously; Reduce difficulty of weaving, be beneficial to the processing of weaving of high-performance fiber.

Operation principle of the present invention is: according to the institutional framework of stereo fabric, through computer programming, by the computer control driver, drive the servo electric jar action, the push rod of servo electric jar is connected with heald frame through certain form (rigidity or flexibility).Therefore, computer program is according to the requirement of stereo fabric institutional framework, makes servo electric jar control heald frame be parked in corresponding accurately position, thereby realizes flexible, various, harness motion accurately.

Compared with prior art, advantage of the present invention is:

1. open loop system adopts many healds, and every opening once can form a plurality of shed opens, satisfies many weft yarns of a plurality of sword head controls and introduces simultaneously, realizes the one-shot forming of labyrinth fabric tissue and three-dimensional woven fabric.This scheme can also significantly reduce the heddle (heald) number, effectively reduces the wearing and tearing of heald to warp thread.

2. the servo electric jar drive unit is introduced opening control, substitute conventional pneumatic or hydraulic system, can carry out high speed and Digital Control to the motion of heald frame, thereby expand the variety type and the specification of fabric greatly.As long as the adjustable height of control servo electric jar cooperates and adopts many healds, can satisfy the requirement of the woven fabric of weaving high thickness.Because servo electric jar has the energy of saving, system's formation is simple, maintenance cost is low, control performance is good and the reliability advantages of higher, for high speed, automation and the Digital Control of complete machine are established good basis.
