Abstract

The utility model provides a rotary shedding mechanism, which belongs to the technical field of textile machinery. The rotary shedding mechanism comprises rotary vanes and threading blocks, wherein the rotary vanes are in central symmetry and are connected by the threading blocks to form a laminar structure; the threading blocks on two opposite surfaces of each rotary vane are arranged up and down relative to the axle wire of the rotary vane; a warp for weaving passes through the middle of the threading blocks; and the rotary vane on the outermost edge is connected with a drive mechanism of a weaving machine. The rotary shedding mechanism can be conveniently connected with a motor, does not need a complicated drive mechanism, and has smaller noises when running.

Description

The swinging shedding mechanism

Technical field

The utility model belongs to textile technology field, is specifically related to a kind of for the swinging shedding mechanism on the loom.

Background technology

Loom claims loom again, is the machinery that lines such as cotton, fiber crops, hair is combined into cloth with the longitude and latitude structural arrangement.The history of loom has had several thousand, in several thousand, loom has had very big development, especially after the industrial revolution, various looms such as Rapier looms, air-jet loom, water jet looms, gripper shuttle loom have appearred, these maximizations, mechanization, intelligentized loom have replaced original manual loom gradually, are applied in the production of cloth.These are weaved cotton cloth and all can have hatch frame, are used for warp is separated up and down, form shed open and pass from the centre for parallel, the shedding mechanism action is rolled in the parallel alternating packets in the warp then, forms shed open again, passes parallel again, repeat above process, line has just formed cloth gradually.

Present shedding mechanism mainly is to use two different heald frames to interlock and moves up and down, the through wires hole that has a row in each heald frame, the warp of space is passed a row through wires hole separately respectively, lift two heald frames and finish opening on warp by staggered.This hatch frame needs complicated transmission mechanism the gyration of motor to be separately converted to the knee-action of two heald frames; And comparatively consume energy during the operation of this shedding mechanism, noise is also bigger.

Summary of the invention

At above problem, the utility model provide a kind of have direct use is rotatablely moved warp is carried out the swinging shedding mechanism of opening.

The technical scheme that its technical problem that solves the utility model adopts is: this swinging shedding mechanism comprises rotary vane, threading piece, described rotary vane center symmetry, use described threading piece to connect between the described rotary vane, form layer structure, arrange up and down in the relative rotary vane of threading piece axis on two opposite faces of every rotary vane, the warp of weaving cotton cloth passes in the middle of the threading piece; The rotary vane at edge links to each other with the transmission mechanism of loom.

As preferably, described rotary vane is oval sheet.

As preferably, described threading piece is cylindric, and the threading piece between per two described rotary vanes uses in pairs, and the warp of weaving cotton cloth passes in the middle of two threading pieces.

As preferably, between the warp-feeding mechanism of described swinging shedding mechanism and loom the elasticity cord grip is housed.

The beneficial effects of the utility model are: each self-forming one row of the threading piece of this swinging shedding mechanism stratiform rotary vane upper-lower position, the warp space of loom pass the threading piece that rotary vane is arranged up and down, form shedding, drive when this swinging shedding mechanism rotates and arrange warp movement between two rotary vanes separately up and down, overlap up to forming opening again, finish the once staggered action of warp; Described swinging shedding mechanism counter-rotating is then finished staggered action again and is reached original position; This swinging shedding mechanism can be connected with motor easily, does not need complicated transmission mechanism, and noise is littler when operation.

The specific embodiment

Further specify below in conjunction with the utility model of embodiment:

Shown in embodiment among Fig. 1, Fig. 2, Fig. 3, this swinging shedding mechanism comprises rotary vane 1, threading piece 2, and described rotary vane 1 center symmetry uses described threading piece 2 to connect between the described rotary vane 1, form layer structure; Arrange up and down in threading piece 2 relative rotary vanes 1 axis on 1 two opposite faces of every rotary vane, the warp 3 of weaving cotton cloth passes in the middle of threading piece 2; The rotary vane 1 at edge links to each other with the transmission mechanism 4 of loom.

As shown in Figure 4, this swinging shedding mechanism uses on loom, threading piece 2 each self-forming one row of its stratiform rotary vane 1 upper-lower position, warp 3 spaces of loom pass the threading piece 2 that rotary vane 1 is arranged up and down, form shedding, the weft inserting apparatus on the loom passes shedding with parallel.Drive when this swinging shedding mechanism rotates and arrange up and down that warp 2 is mobile between two rotary vanes separately, arrive position as shown in Figure 5, warp 3 overlaps, and this moment, the parallel of loom stepped up the parallel jam-packed that device will pass in the opening of warp 3.Described swinging shedding mechanism continues counter-rotating up to forming opening again then, finishes the once staggered action of warp as shown in Figure 6; Continue to add the latitude jam-packed, described swinging shedding mechanism counter-rotating is then finished staggered action again and is reached original position.

This swinging shedding mechanism can be connected with motor easily, do not need complicated transmission mechanism, positive and negative the transferring that can directly use motor finished described shedding mechanism and rotated and reverse, and perhaps uses four-bar mechanism that the rotation that motor continues is converted into the rotating of swinging shedding mechanism.Because this device does not have moving up and down of heald frame on the common loom shedding mechanism, noise is littler when operation.

As shown in Figure 2, described rotary vane 1 is oval sheet.The opening that forms when warp 3 passes of this swinging shedding mechanism is bigger like this, and the weft inserting apparatus that is beneficial on the loom passes shedding with parallel, makes the weft inserting apparatus design more simple.

As depicted in figs. 1 and 2, described threading piece 2 is cylindric, and the threading piece 2 between per two described rotary vanes 1 uses in pairs, and the warp 3 of weaving cotton cloth passes in the middle of two threading pieces 2.The shape unanimity of all described threading pieces 2 adopts wear-resisting material to make, and the face of cylinder of described threading piece 2 is adding should try one's best man-hour smooth, the frictional force when passing to reduce warp 3.

As shown in Figure 4, between the warp-feeding mechanism of described swinging shedding mechanism and loom elasticity cord grip 5 is housed.Described elasticity cord grip 5 comprises depression bar 51 and spring part 52, and 52 pairs of described depression bars 51 of described spring part are exerted pressure warp 3 is compressed.Can guarantee that like this warp 3 is in tensioned state when described swinging shedding mechanism rotates always, make things convenient for the stable of shedding shape, improve the quality of cloth.
