Abstract

The utility model revolutionarily improves a jacquard loom electromagnetic valve by placing two groups of electromagnetic coils into the same valve body, sharing one electrode by the two groups of electromagnetic coils and realizing electrical connection with outside through three contact pins parallelly placed inside a locking groove of the valve body. Besides, two pull-in surfaces are respectively formed on two sides of the valve body by each group of the electromagnetic coils; two pull-in surfaces on the same side serve as a working surface; two upright needle hooks arranged at the tail portion of the valve body are used for hooking upright needles lifted by a jacquard loom; each electromagnetic valve can simultaneously and independently control movement of the two upright needles; magnetic steel is installed at the tail end of a distance piece; deviation and malfunction of the upright needles drawn with the pull-in surfaces can be decreased by the function of the magnetic steel; hooks capable of closely matching are arranged on a cover plate; and the cover plate is tightly compressed on the valve body by the hooks, thereby having fixing and dustproof functions for the contact pins and the electromagnetic coils. Simultaneously, the design mode of rapid connection is capable of improving the assembly work efficiency of the electromagnetic valves.

Description

Solenoid valves for jacquard

Technical field

The utility model relates to a kind of solenoid valves for jacquard, particularly a kind of electromagnetic valve that two groups of solenoids are placed in the valve body and can work alone simultaneously.

Background technology

Solenoid valves for jacquard is used in electronic jacquard machine, and the signal of telecommunication that it time will characterize the fabric style in work converts the lifter motion of corresponding warp thread to, is the executive component of key extremely in the automatic jacquard weaving system.

Solenoid valves for jacquard commonly used at present is installed in the valve body after generally adopting inner two coils series connection, and each electromagnetic valve can only be controlled the motion of a needle.Conventional electronic jacquard machine need be installed 2688 pins, needs 2688 electromagnetic valves.Like this, the volume of the tap of jacquard is just very big, need occupy bigger space, and the electronic jacquard machine overall weight also increases greatly simultaneously.So not only increase the manufacturing and the cost of transportation of electronic jacquard machine, and used the textile production producer of electronic jacquard machine will take bigger factory building.Manufacturer and use producer to electronic jacquard machine all are a kind of huge wasting of resources undoubtedly.

And the electronic jacquard machine needle only relies on the adhesive of electromagnetic valve to move, and just occurs departing from and the misoperation phenomenon easily after the work regular hour, causes percent defective to increase, and work efficiency reduces.If increase the misoperation rate that a kind of device that can proofread and correct and rectify a deviation needle will significantly reduce electromagnetic valve, thereby use producer to improve work efficiency, reduce maintenance cost and play good effect jacquard.

Summary of the invention

In order to reduce the volume of jacquard tap, motion is proofreaied and correct and is rectified a deviation to the jacquard needle, contact pilotage and solenoid are prevented dust, the utility model provides a kind of solenoid valves for jacquard, this solenoid valves for jacquard places two groups of solenoids in the valve body and can work alone simultaneously, not only dwindled the volume of jacquard tap, can also proofread and correct and rectify a deviation, can prevent dust to contact pilotage and solenoid simultaneously jacquard needle motion.

The technical scheme that its technical problem that solves the utility model adopts is: two groups of solenoids are placed in the same valve body, two groups of shared electrodes of solenoid, be electrically connected with outside the realization by three contact pilotages that are placed on side by side in the valve body draw-in groove, every group of solenoid forms two adhesive faces in the both sides of valve body, two adhesive faces of homonymy are as a working face, the afterbody of valve body has two perpendicular pin hooks, the perpendicular pin that jacquard is mentioned carries out hook, and every electromagnetic valve can be controlled the motion of two perpendicular pins simultaneously separately.The tail end of partition has been laid magnet steel, by the effect of magnet steel, can reduce with the perpendicular pin of adhesive face adhesive and to depart from and misoperation.On the cover board designed the close-fitting hook of energy, by hook cover plate has been pressed on above the valve body, thereby contact pilotage and solenoid are played fixing and dustproof effect, the design of connection also can improve the assembling work efficiency of electromagnetic valve simultaneously fast.

The beneficial effects of the utility model are: make solenoid valves for jacquard volume-diminished ratio surpass 80%, save a lot of raw material simultaneously, not only can reduce production costs and freight, and use the textile production producer of jacquard can save a large amount of production lands used; By the magnet steel of laying on the partition, can proofread and correct and rectify a deviation needle motion, reduce the misoperation rate of needle, improved work efficiency; Design the hook of quick plug-in type on the cover plate, can improve the production and assembly work efficiency of electromagnetic valve.

The specific embodiment

Embodiment 1: lay contact pilotage 2 and solenoid 3 on the valve body 1 of injection mo(u)lding, with solenoid 3 two one group of formation that are connected in series at interval, be welded on wherein on of contact pilotage 2 behind two groups of shared electrodes, each connects an other end of every group of electromagnet with other two root bead of contact pilotage 2 and links to each other;

Solenoid 3 each side at valve body 1 of every group of series connection form two adhesive faces 4;

End at valve body 1 has two outstanding perpendicular pin hooks 5, the perpendicular pin of jacquard is played the effect of hook;

On partition 6, lay magnet steel 7, the motion of perpendicular pin is played the effect of proofreading and correct and rectifying a deviation;

There is the cover plate 8 of hook 9 to be crimped on design and forms the whole valve body of finishing on the valve body 1.

The valve body 1 that assembles forms a complete electromagnetic valve after cooperating partition 6 single groups or organizing proper alignment more.

Being preferred embodiment of the present utility model only in sum, is not to be used for limiting practical range of the present utility model.Be that all equivalences of doing according to the content of the utility model claim change and modification, all should be technology category of the present utility model.
