The utility model has the advantages of simple structure and high working speed, and the production efficiency of the jacquard weave can be raised.

Description

Electromagnetic wire

A kind of Electromagnetic wire device that relates to the textile machine shedding mechanism.

The shedding mechanism of woven loom can be divided into sheet and combine and two kinds of twine helads.The comprehensive one group of heald soon of so-called sheet is installed on the same framework, i.e. heald frame.Adopt two or multi-disc heald frame when weaving,, move up and down, form fell thereby drive warp thread as each sheet heald frame of drives such as cam or dobbies by mechanical driving device.This shedding mechanism movement velocity is fast, can match with weft insertion device at a high speed, but be subjected to the restriction of heald frame sheet number, generally can only weave cellulose fabric;

Twine helad is by " line " each heald to be associated in together with corresponding perpendicular pin, by the motion of card by the perpendicular pin of eedles control.Driving heald when perpendicular pin moves upward mentions, the falling of heald then will be driven by gravity by the comprehensive hammer that the heald lower end hangs, as jacquard weaving machine, because its each heald can be controlled respectively, so can weave complicated loom figured, but its transmission complexity, speed is low, and rising and falling of each heald control by card, and product design and variety renovation be more complicated all.And changing a kind will the transducer set card, and cost is higher, though now computer-controlled jacquard is arranged, generally all can not save embossing plate operation.

The purpose of this utility model provides a kind of Electromagnetic wire device, and bonding pad is combined and the twine helad advantage, can reach the speed that sheet is combined shedding mechanism, the processing performance that has twine helad shedding mechanism excellence again, and overcome its shortcoming, saved card, simplify the operation of product design and replacing kind.

The utility model is achieved in that as shown in Figure 1, its principal character is to drive heald with electromagnetic mode to move up and down, the rank sheet of power-on and power-off magnetic driven device welds with heald respectively, its electromagnetic driver is connected with control system by socket, cable, cable connect power supply get electric after, produces strong magnetic field and inhales moving rank sheet, drive heald and make progress, move downward, drive movement of the warp by harness eye and form fell, finish the opening process.Because general fabrics total quantity of warps (for 160cm fabric width) about thousands of, therefore, require the size of electromagnetic driver must be very thin, adopt the heat radiator type shell for this reason, can use thinner lead coiling like this, to reduce its size.For improving the shedding power of Electromagnetic wire device, the rank sheet adopts B _SThe material that (saturation induction density) value is high is made, and heald can adopt common structure and material.

The utlity model has following advantage:

1, the utility model can be controlled respectively each heald, thereby can reach the processing performance of twine helad, can weave the cellulose fabric and the loom figured of any complex organization;

2, the utility model can be applicable to computer and carries out product design, and more new varieties only need be changed corresponding control programs (disk) and get final product;

3, the utility model can adopt Warp tying machines to carry out automatic tying-in, can satisfy various technological requirements, has saved the complicated operation of gaiting;

4, the utility model has saved the complicated mechanical transmission device, and opening is steady, improves weave quality, and opening speed is fast, can cooperate with weft insertion device at a high speed, as projectile shuttle, device bar, water spray etc., thereby improves the production efficiency of big jacquard weaving.

Concrete structure of the present utility model is provided by following implementation column and accompanying drawing thereof.

Fig. 1 is the utility model overall structure schematic diagram;

Fig. 2 is the utility model combined electromagnetic driving device structure schematic diagram.

Below in conjunction with accompanying drawing in detail the concrete structure of the utility model and operational detail are described in detail.

As shown in Figure 1.

The Electromagnetic wire device by power-on and power-off magnetic driven device 17,11 and heald 8 consist of.

Have upper cover 1, filler 2, fixed core 3, heat radiator type shell 4, coil rack 5, coil 6, rank sheet 7, installing hole 18, contact pin 19 on the electromagnetic driver 17, jack 20, connecting socket 21, tie cable 22, upper cover 1 is used for sealing filler 2, and be contact pin 19 location, filler 2 places heat radiator type shell 4 interior tops, with loam cake 1, contact pin 19 admittedly Fixed, be used for improving heat dispersion; Filler 2 belows are that fixed core 3 is bonded together with coil rack 5, are used for improving magnetic induction intensity, and hold in the mouth the stroke of sheet 7 by the vertical direction size restrictions. Fully flood with resin between heat radiator type shell 4 and the coil 6, to obtain good radiating effect; Coil 6 is on coil rack 5, and rank sheet 7 places in the cavity tracks of coil rack 5, and the magnetic field that coil produces drives the motion of rank sheet 7 easy on and off; With the heald 8 of harness eye 9, weld with

rank sheet

7,10 respectively at its two ends, drives movement of the warp by the harness eye 9 on it and form fells; Installing hole 18 is open-works, passes shell 4 and filler 2 with each Electromagnetic wire combination also together, is installed on the fixing framework, sees shown in Figure 2; Contact pin 19 is the lead terminal of coil 6, by socket 21 and on jack 20 and cable 22 be connected with computer control system.

Electromagnetic driver 17,11 structure are identical, rank sheet 10, electromagnetic driver 11, installing hole 12, coil lead jack 13, connecting socket 14, tie cable 15, jack 16, and its connected mode is omitted narration.

Embodiment: combined electromagnetic heald device

As shown in Figure 2, each Electromagnetic wire is installed on the fixed frame by installing

hole

12,18 and forms a row, according to the requirement of fabric, can adopt many row's structures, and each stroke of arranging Electromagnetic wire can be designed to different, thereby forms clear opening; Also can be designed to identically, form unintelligible opening.

Each Electromagnetic Drive apparatus all is attached to the computer output loop respectively by

cable

15,22, when weaving, require going up or following electromagnetic driver 17 or 11 of conducting Electromagnetic wire respectively by computer according to fabric, by heald 8, harness eye 9 drives warp thread and makes progress, moves downward (as shown in phantom in FIG.), forms fell.At this moment, provide a picking signal by computer, start the weft insertion device picking, picking is returned a signal by weft insertion device and is delivered to computer control system after finishing, and begins opening next time, carries out a new working cycles.

For fear of power-on and power-off magnetic driven device 17,11 simultaneously electric, damage heald 8, destroy picking, should in computer control system, be provided with and interrupt protection.
