Abstract
The present invention relates to a needle selecting device for electronic jacquard weave, which is characterized in that each unit of the needle selecting device is composed of an upper vertical needle 1, a shelf board 2, a control plate 3, an electromagnetic valve 4, a release assisting board 5, lower vertical needles 6a and 6b, griffes 7a and 7b, and a needle hanging board 8, wherein the upper end of the upper vertical needle 1 is provided with a suction head. Compared with the prior art, the scheme of the needle selecting device has outstanding advantages that a magnetic gap between the electromagnetic valve and the suction head 11 of the upper vertical needle can be eliminated, the energized current of the electromagnetic valve is small, the current is only 20% of the energized current of the existing similar electromagnetic valves, the temperature increment is low, and no overload protecting circuit needs to be arranged. The release assisting board 5 is arranged to overcome the effect of magnetic hysteresis, and is helpful to enhance the weaving speed of a jacquard loom; the operation is stable and reliable.
Description
Technical field
The present invention relates to a kind of double lift jacquard, particularly a kind of electronic jacquard needle selector.
Background technology
Existing electronic jacquard needle selector, the electronic jacquard needle selector that uses on the broadcloth electronic jacquard machine as the Britain Bonus machinery Bonas MachineCompany Ltd of Co., Ltd design, it connects warp thread with two steel lifting-hooks of a solenoid control by pulley and rope, lifting-hook is shelved on respectively and griffes, and follow and griffe to pump, when electromagnetic valve is switched on, a lifting-hook and griffe to rise to this lifting-hook and stop hanging on the hook, follow another lifting-hook and griffe and rise, warp thread is raised the formation shed open.The defective of existing electronic jacquard needle selector is the gap that has 2 millimeter between electromagnetic valve and the perpendicular pin; the electric current of electromagnetic valve coil energising is bigger; the electrical current of each coil reaches 160～170mA; cause coil power consumption big; temperature rise; the complicated overload protecting circuit of essential configuration requires high simultaneously to the electromagnetic valve material.
Summary of the invention
The object of the present invention is to provide a kind of electronic jacquard needle selector of novel structure; overcome the existing in prior technology defective; electromagnetic valve has the suction of helping function; be provided with control panel; the electric current of electromagnetic valve energising is greatly reduced; electrical current is 32mA only, need not to dispose complicated overload protecting circuit, moves more reliable.
A kind of electronic jacquard needle selector, comprise frame, perpendicular pin, electromagnetic valve, griffe, the tuck plate, it is characterized in that: each needle selection unit of this needle selection device is by last perpendicular pin 1, shelf 2, control panel 3, electromagnetic valve 4, help and put plate 5, following perpendicular pin 6a and 6b, griffe 7a and 7b, tuck plate 8 constitutes, wherein shelf 2, help and put plate 5, tuck plate 8 is installed on the frame, electromagnetic valve 4 and griffe 7a and 7b and pump, and control panel 3 is done left and right sides reciprocating motion, have the through hole that is used to arrange perpendicular pin 1 on shelf 2 and the control panel 3, a side that goes up perpendicular pin 1 middle part is provided with layout and helps the breach of putting plate 5, and its top is provided with suction nozzle 11, and control panel 3 swings are followed in its underpart; Suction nozzle 11 by slide opening 11a, put suction piece 11d, the bearing pin 11e that sheet 11b, elastomer 11c, pure iron make and form, slide opening 11a opens on the neck of last perpendicular pin 1, inhale have on the piece 11d one with last perpendicular pin 1 neck vertical through holes and horizontal through hole that installation bearing pin 11e uses movingly, put sheet 11b, elastomer 11c, inhale piece 11d and be sleeved on successively on perpendicular pin 1 neck, bearing pin 11e passes the horizontal through hole of inhaling piece 11d fixedlys connected with suction piece 11d with slide opening 11a.Shown in unit, Fig. 1 left side, electromagnetic valve 4 energisings that work pumps, contact with the suction piece 11 of last perpendicular pin 1, electromagnetic valve 4 rises, go up perpendicular pin 1 and be raised, mention its upper end of following perpendicular pin 6b that puts in place and do not contact with the lower end of going up perpendicular pin of swing by griffing 7b, promptly going up perpendicular pin, can not to stir down perpendicular pin top mobile laterally, so down the hook on the perpendicular pin 6b just stops to hang on the tuck plate 8, then griffe 7a and mention down perpendicular pin 6a and form shed open; Shown in right unit among Fig. 1, if the electromagnetic valve no power owing to rest the effect lower swing of the perpendicular pin of going up of shelf 2 at control panel 3, leaves the following perpendicular pin top thruster outward that rising puts in place, hook on the perpendicular pin can't stop to hang on the tuck plate 8 down, can not make corresponding warp thread form shed open.
With prior art relatively, outstanding advantage of the present invention is: (1) is provided with control panel 3, and upward perpendicular pin length shortens dramatically, and weight saving alleviates the work load of electromagnetic valve, makes electromagnetic valve only play on-off action; (2) owing to the electromagnetic valve of doing to pump directly contacts with suction nozzle 11, formation helps the suction effect, eliminate the magnetic gap between electromagnetic valve 4 and the last perpendicular pin suction nozzle 11, add that the electromagnetic valve work load is light, the electromagnetic valve electrical current is 32mA only, and existing like product electromagnetic valve electrical current is 160～170mA, and electromagnetic valve reduces power consumption 80%, temperature rise is low, need not to dispose complicated overload protecting circuit; (3) be provided with to help and put plate 5, be used to overcome the magnetic hysteresis influence after the electromagnetic valve work, help to improve the reliability of needle selection device work, and improve the weaving speed of jacquard weaving machine effectively.Adopt the electronic jacquard needle selector of abovementioned technology, its integrated performance index all is better than existing like product.
