Description
Technical field
The present invention relates to the improvement of a kind of textile machine large jacquard weave novel opening device, specifically a kind of magnetic control vapour-pressure type large jacquard weave opening control device.
Background technology
Existing following technology: one, the transmission of the jacquard information of BONAS electronic jacquard machine and execution;
1, magnetic board principle: jacquard information utilizes serial to distribute, Long line transmission mode, delivers to jacquard head via interface plate, and transmission range can reach 40m, delivers to the electromagnetism valve plate of jacquard head.Electromagnetism valve plate is distributed to through interface card through the jacquard weave data message of Long line transmission and control information, after wherein data message serial is assigned to each electric valve plate, under the effect of control signal, run simultaneously and export the control of realization to the lifting/lowering warp of jacquard weaving machine, weave the figure of every shuttle in real time by jacquard weave data.
2, electromagnetic force changes mechanical force into: the operation principle that electromagnetic force changes mechanical force into will divide four working stages to carry out setting forth as shown in Figure 10.
In the stage 1: left side sheet hook B promotes, the right sheet hook A declines, heald C motionless (i.e. heald not opening);
In the stage 2: left side sheet hook B rises, the right sheet hook A declines, and in pulley, rise and fall are offset, and heald C is still motionless; In the stage 3: during the sheet hook rising peak of the left side, electromagnetic valve powers up, and B sheet hook is tangled by adhesive, and namely left side sheet hook B maintains static, when the right sheet hook A promotes, heald C moves up, and produces opening;
In the stage 4: on the sheet hook A of the right, left side sheet hook B stays peak, and sheet hook A rises to peak when the right, produce maximum open.
Staubli electronic jacquard machine: operation principle is substantially identical compared with BONAS, just the complexity of mechanism is different, and the mechanism of Staubli is comparatively complicated, as shown in figure 11.Hook when the movable hook on left (right side) is kept hook, when right (left side) griffes up to move, heald is just raised, formation top shed, otherwise is lower shed.
Two, cylinder principle
Cylinder is made up of cylinder barrel, end cap, piston, piston rod and seal etc., its internal structure as shown in the figure:
SMC cylinder principle as shown in figure 12.
1) cylinder barrel
The internal diameter size of cylinder barrel represents the size of cylinder power output.Piston will do and reciprocatingly slide stably in cylinder barrel, and the surface roughness of cylinder barrel inner surface should reach Ra0.8 μm.
SMC, CM2 cylinder piston adopts combined seal ring to realize two way seal, and piston links with pressing, without nut with piston rod.
2) end cap
End cap is provided with intake and exhaust port, and what have is also provided with buffer gear in end cap.Bar side end cap is provided with sealing ring and dust ring, to prevent from outwards leaking gas from piston rod and preventing external dust to be mixed in cylinder.Bar side end cap is provided with fairlead, to improve the guiding accuracy of cylinder, bears lateral load a small amount of on piston rod, reduces the lower curved amount of piston rod when stretching out, and extends cylinder service life.Fairlead uses oil-impregnated sintered alloy usually, lean forward copper casting.End cap is in the past conventional malleable cast iron, antirust for weight reduction, often use aluminium alloy compression casting, and small-bore cylinder has and uses brass material.
3) piston
Piston is the part that is stressed in cylinder.For preventing the two mutual gas blowbies in chamber about piston, be provided with piston packing.Wear ring on piston can improve the guidance quality of cylinder, reduces the abrasion of piston packing, reducing friction resistance.Wear ring is long uses the materials such as polyurethane, polytetrafluoroethylene (PTFE), folder cloth synthetic resin.The width of piston is decided by sealing ring size and necessary slipper length.Slipper is too short, easily causes premature wear and stuck.The material Aluminium Alloys in Common Use of piston and cast iron, the piston of small-sized cylinder has brass to make.
4) piston rod
Piston rod is most important stressed part in cylinder.Usual use high-carbon steel, surface is through hard chrome plating process or use stainless steel, with anticorrosion, and improve the ABRASION RESISTANCE of sealing ring.
5) sealing ring
The seal parts of revolution or reciprocating motion place is called movable sealing, and the sealing of static element part is called static seal.
The method of attachment of cylinder barrel and end cap mainly contains following several:
Monolithic devices, riveted, thread connection type, flange-type, pull rod type.
6) mist of oil in pneumatically is wanted to lubricate piston during cylinder operation.Also fraction is had to exempt from lubricating cylinder.
So the shortcoming of prior art causes: 1. existing large jacquard controlling organization is complicated, even electronic jacquard also needs the jacquard head of Extremely volume; 2. existing large jacquard dynamic structure connects complicated, needs mechanical device more; 3. each electromagnetic valve of existing large jacquard and sheet hook need to provide separately enough abilities, and power consumption is larger relatively.
