Description
Technical field
The utility model relates to a kind of needle selecting device of electronic jacquard machine.
Background technology
From present domestic electronic jacquard machine market, the electromagnetic valve that homemade electronic jacquard machine uses is all similar with the electromagnetic valve structure of external manufacturer production such as BONAS, STAUBLI, its quality is compared with the electromagnetic valve of import and is also existed a certain distance, and along with going deep into of using, a series of problem has in use also appearred in external electromagnetic valve, high as the power consumption of: BONAS electromagnetic valve, the bulky equipment volume that causes is huge and be unfavorable for that maintenance and development large needle count jacquard; STAUBLI electromagnetic valve structure compactness but radiating effect is poor, complicated boosting suction spindle mechanism lost efficacy easily, pulley is fixed on the semi open model structure in the electromagnetic valve component, feasible very high to the requirement of electronic jacquard machine sealing, improved the manufacture difficulty of equipment and the requirement that has improved conditions for equipment use greatly.
And the use of domestic electronic jacquard machine never obtains the good market development, maximum reason be exactly in the electronic jacquard machine the needle selection parts---the Performance And Reliability of electromagnetic valve is not well solved.All manufacturers all produce electromagnetic valve voluntarily, but do not have producer from operation principle, instructions for use, and deep research and analysis on the material behavior all are that low side is imitated, and can't surmount.
So use the confidential worry quality of domestic electronic jacquard not pass a test and keep in repair inconvenient problem.Use external electronic jacquard machine, though secure equipment cost of quality and accessory cost height, the recovery of the capital cycle is long, so, extremely need a rational needle selecting device of development and Design, can embody easy to maintenance, high efficient and reliable, advantage of low energy consumption.
The utility model content
The purpose of this utility model is to provide a kind of needle selecting device of electronic jacquard machine, and it is small and exquisite that device of the present utility model has structure, easy to maintenance, long service life, and high efficient and reliable, energy consumption is low, and environment for use is required low characteristics.
In order to achieve the above object, the technical solution of the utility model is:
A kind of needle selecting device of electronic jacquard machine comprises rack-mounted assembly pulley, griffe, needle, electromagnetic valve, and assembly pulley and needle flexibly connect, needle with griffe to flexibly connect; The boosting projection is installed on the described needle; Described electromagnetic valve comprises valve body, electromagnet, and movable hook, returning spring wherein is equipped with electromagnet and movable hook on the valve body, and is installed with returning spring on the movable hook.
Described movable hook is provided with 2; Supportingly be provided with 2 returning springs.
Described boosting projection is the projection of a band arc, and its distance between the minimum point on the peak of centre and both sides is 2-3mm.
Beneficial effect of the present invention is: it is small and exquisite that device of the present utility model has structure, easy to maintenance, long service life, and high efficient and reliable, energy consumption is low, and environment for use is required low characteristics.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, the needle selecting device of a kind of electronic jacquard machine of the utility model indication comprises rack-mounted assembly pulley 1, griffes 2, needle 3, electromagnetic valve, and assembly pulley 1 flexibly connects with needle 3, needle 3 with griffe 2 to flexibly connect; On the described needle 3 boosting projection 4 is installed; Described boosting projection 4 is the projection of a band arc, and its distance between the minimum point on the peak of centre and both sides is 2-3mm; Described electromagnetic valve comprises valve body 5, and 7,2 returning springs 8 of 6,2 movable hooks of electromagnet wherein are equipped with electromagnet 6 and movable hook 7 on the valve body 5, and are installed with returning spring 8 on the movable hook 7.Infinitely close between boosting projection 4 and the movable hook 7, but do not contact.
About two griffe 2 to use at conjugate cam, pump relatively.Needle 3 is along with griffing 2 when moving up and down, if electromagnet 6 is no power always, then movable hook 7 is fixed in the valve body 5 by returning spring 8, though when the extreme higher position, boosting projection 4 extrudes valve bodies to movable hook 7, be positioned at outside the hole 9 that is provided with on the needle 3, but needle 3 is when descending, movable hook 7 is got back in the valve body 5 immediately, and this moment, needle 3 can not hooked.Assembly pulley 1 is positioned at low level, and corresponding warp thread is positioned at lower floor's yarn mouth.
If needle 3 moves to the extreme higher position, electromagnet 6 energisings this moment, because the peak of the boosting projection 4 on the needle 3 has withstood movable hook 7, movable hook 7 is pushed to electromagnet 6, produce suction under the electromagnet 6 energising situations, just one of movable hook is tightly inhaled on electromagnet 6, electromagnet only need keep very little suction to overcome the restoring force of returning spring, just can guarantee that movable hook 7 is firmly held.This moment, boosting projection 4 extruded valve bodies to movable hook 7, was positioned at outside the hole 9 that is provided with on the needle 3, was hooked by movable hook 7 when making needle 3 declines, and needle 3 has just been stayed on the extreme higher position like this, up to griffe 2 to move to peak and electromagnet 6 no powers next time.Simultaneously, because another side griffes 2 to drive needles 3 and do ascending motion, so assembly pulley 1 moves upward, corresponding warp thread is positioned at upper strata yarn mouth.
For guaranteeing that electromagnet 6 can have most economical energy loss-rate, must move to the energising of peak position conduction time at needle 3, just discharge when needle 3 declines are hooked by movable hook 7, and move distance is 5-6mm, be 8-10 degree/180 degree conduction time, and dutycycle is very high.Low pick-up voltage (12V) and high accounting are the effective ways that cuts down the consumption of energy.Between electromagnetic valve of the present invention and needle 3 and the assembly pulley 1 is Open architecture, and the heat that distributes of electromagnet 6 can be the fastest like this distributes and can not accumulate on the electromagnet 6, makes the electromagnetic valve life-span be improved to greatest extent.
