Description

Electronic jacquard needle selector

The utility model relates to a kind of double lift jacquard, particularly a kind of electronic jacquard needle selector.

Existing electronic jacquard needle selector, the electronic jacquard needle selector that uses on the broadcloth electronic jacquard machine as the Britain Bao Nasi machinery Bonas Machine CompanyLtd of Co., Ltd design, it is with two steel lifting-hooks of a solenoid control, connect warp thread by pulley and rope, lifting-hook is shelved on respectively and griffes, and follow and griffe to pump, when electromagnetic valve coil is switched on, a lifting-hook and griffe to rise, stop hanging on the hook to this lifting-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.

The purpose of this utility model 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, electromagnetic valve 4, perpendicular pin 6a and 6b, griffe 7a and 7b, tuck plate 8, it is characterized in that electromagnetic valve 4 pumps, between electromagnetic valve 4 and perpendicular pin 6a and 6b, be provided with balancing point 1, shelve the shelf 2 of balancing point 1 and drive balancing point 1 and make the reciprocating control panel 3 in the left and right sides, have the through hole of arranging balancing point 1 usefulness on shelf 2 and the control panel 3, shelf 2 is fixed on the frame, and a side at balancing point 1 middle part is provided with layout and helps the breach of putting plate 5, this helps puts plate 5 and is fixed on the frame, and suction nozzle 11 is equipped with in balancing point 1 upper end; Suction nozzle 11 is by slide opening 11a, put sheet 11b, elastomer 11c, the suction piece 11d that pure iron is made, bearing pin 11e forms, slide opening 11a is out the vertical through holes on balancing point 1 shoulder, on this shoulder, put successively and put sheet 11b, elastomer 11c, inhale piece 11d, bearing pin 11e passes slide opening 11a and is connected as a single entity with suction piece 11d, when electromagnetic valve 4 contacts with suction piece 11d, inhale piece 11d and can do moving up and down of trace, guarantee inhaling between piece 11d and the electromagnetic valve 4 is that no gap contacts, play the suction effect that helps, improve the reliability of needle selection device work thus, can reduce the electrical current of electromagnetic valve coil simultaneously and reduce coil temperature rise.Shown in left unit among Fig. 1, electromagnetic valve 4 energisings that work pumps, contact with the suction nozzle 11 of balancing point 1, electromagnetic valve 4 rises, balancing point 1 is raised, and mentions its upper end of perpendicular pin 6b that puts in place and does not contact with the lower end of the balancing point 1 of swing by griffing 7b, and promptly balancing point can not be stirred perpendicular pin top and moves laterally, so the hook on the perpendicular pin 6b just stops to hang on the tuck plate 8, then griffe 7a and mention 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 balancing point of shelf 2 at control panel 3, leaves the perpendicular pin 6b top thruster outward that rises to the position, the hook that should erect on the pin can't stop to hang on the tuck plate 8, can not make corresponding warp thread form shed open.

With existing technology relatively, outstanding advantage of the present utility model is: (1) is provided with control panel 3 and balancing point 1, alleviates the work load of electromagnetic valve, makes electromagnetic valve 4 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 balancing point 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 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.

Fig. 1 is the structural representation of electronic jacquard needle selector of the present utility model.

Fig. 2 is the structure partial cutaway view of suction nozzle 11.

A kind of electronic jacquard needle selector, Fig. 1 are represented two needle selection unit of this needle selection device, each needle selection unit by balancing point 1, shelf 2, control panel 3, electromagnetic valve 4, help and put plate 5, perpendicular pin 6a and 6b, griffe 7a and 7b, tuck plate 8 and constitute.The suction nozzle 11 of balancing point 1 upper end by slide opening 11a, put suction piece 11d, the bearing pin 11e that sheet 11b, elastomer 11c, pure iron make and form.When electromagnetic valve 4 energisings, corresponding warp thread forms shed open.Electromagnetic valve 4 strokes are 6 millimeters, and the range of griffing is 110 millimeters, and minimum stroke is 50 millimeters, forms shed open clearly, and for the jacquard of 1500 pins, its needle selection device adopts 1500 balancing points, and 3000 perpendicular pins, weaving speed are per minute 450 shuttles.
