Abstract

The utility model relates to the electromagnetic harness lifting control device of a double action type electronic jacquard machine. The utility model is characterized in that an electromagnetic valve 7 is arranged in the middle of a casing 4, two permanent magnets 1 are inserted into the slot at the edge of the casing 4, and two magnetically conductive iron hooks 2 are respectively positioned between the electromagnetic valve 7 and the permanent magnets 1 and are sleeved on the sliding sleeve shaft (3). The thread lifting hook 8 and the thread lifting hook 9 respectively carry out relatively up-and-down movement in the chutes at both sides of the plastic casing 4, and the corresponding warp thread is lifted to form a shed when the thread lifting hook 8 or the thread lifting hook 9 is caught by the magnetically conductive iron hooks 2. Compared with the prior art, the utility model has the remarkable advantages that the electric current in the electromagnetic valve coil is very small, the energy consumption of the electromagnetic valve 7 is rather small and is only about 0.1W, and the electromagnetic valve scarcely heats. Because the spring is replaced by the permanent magnet, the width of the iron core of the electromagnetic valve is reduced and further the whole volume is smaller so that the utility model is favorable for manufacturing a large-scale needle number jacquard machine.

Description

The electromagnetism shedding controller of electronic jacquard machine

Affiliated technical field

The utility model relates to a kind of electromagnetism shedding controller of double-lift electronic jacquard machine.

Background technology

Current, a kind of general character of double-lift electronic jacquard machine electromagnetism shedding controller, it all is effect by electromagnetic valve, control along with the sheet hook or the thread-lifting hook of griffing to do upper and lower motion catch on or do not collude, sheet hook or thread-lifting hook are promoted or descend to form the warp thread shed open, history pottery Bill electronic jacquard machine world-famous in the world also is this device.The structure of this device pumps on the slide guide rail by griffing to drive thread-lifting hook for an electromagnetic valve, a pair of magnetic conduction cleek and fixedly slide-bar, a pair of thread-lifting hook, a pair of spring and some fixtures of magnetic conduction cleek are housed in plastic casing.When thread-lifting hook rose to the extreme higher position, the boosting mechanism on the thread-lifting hook promoted the magnetic conduction cleek and relies on the electromagnetic valve iron core, at this moment, if give coil electricity, the electromagnetic valve iron core holds the magnetic conduction cleek, and thread-lifting hook can not be hung on the magnetic conduction cleek, and can not mention the formation shed open by the effect warp thread of assembly pulley; If do not give coil electricity, spring promotes the magnetic conduction cleek and resets, and this moment, thread-lifting hook can hang on the magnetic conduction cleek, and was raised the formation shed open by the effect warp thread of assembly pulley.Its shortcoming is: when the electromagnetic valve iron core holds the magnetic conduction cleek, must overcome the thrust of spring, so the coil electricity electric current is still bigger, easily heating; Adopt spring reset, in long high speed stretching motion, spring very easily produces fatigue, causes the hook action malfunctioning, influences life of product.Also have at home and adopt permanent magnet to reset, as Chinese patent 95203911.7 electronic jacquard machine electromagnetic needle selectors, 02145175.3 electronic jacquard machine sheet hook lash-selecting mechanism etc., its shortcoming is; They adopt permanent magnet are contained on sheet hook or the hook, when no power, permanent magnet and electromagnetic valve iron core hold, the electromagnetic valve iron core is magnetized by permanent magnet, when switching on, need to consume a part of power and could be magnetized into the N utmost point identical or the S utmost point to the electromagnetic valve iron core, and repel mutually and push open with permanent magnet polarity to electromagnetic valve coil, so consumed power is bigger, heating easily.

Summary of the invention

In order to overcome big, the easy shortcoming such as heating of electromagnetic valve consumed power.The utility model electromagnetism shedding controller has adopted, structurally spring has been changed into permanent magnet, and make full use of the characteristic principle of magnetic, make the more power saving of this electromagnet heald lifting device, basically eliminated the electromagnetic valve heating problem, and volume also dwindled much, helps the manufacturing that large-scale pin is counted electronic jacquard machine.

The technical scheme that the utility model device solves technical problem is taked is: this device comprises: a pair of permanent magnet 1, a pair of magnetic conduction cleek 2, a pair of slide-bar 3, housing 4, iron core 5 (comprising that suction nozzle 11 a pair of, following suction nozzles 12 are a pair of on the iron core), coil 6, electromagnetic valve 7, thread-lifting hook 8 and thread-lifting hook 9 are a pair of, and one group of assembly pulley etc.Two permanent magnets 1 insert in the slot at plastic casing 4 edges fixing, lay respectively at two magnetic conduction cleek 2 outsides, and and the electromagnetic valve iron core on suction nozzle 11 a pair of symmetries.Permanent magnet 1 faces the polarity of suction nozzle 11 on the iron core, and the electromagnetism polarity in the time of must switching on suction nozzle on the iron core 11 is identical.Two magnetic conduction cleeks 2 slide over respectively on the slide-bar 3, and slide-bar 3 is located at the both sides of suction nozzle 12 under the iron core respectively, and reduce the magnetic gap between the suction nozzle 12 under magnetic conduction cleek 2 and the iron core when design as far as possible, play the magnetic loop effect when coil electricity.Electromagnetic valve 7 is fixed in the middle of the plastic casing 4.Thread-lifting hook 8 and thread-lifting hook 9 also slide up and down by griffing to drive in the guide runner of the both sides of plastic casing 4 respectively.

The utility model device outstanding feature is: the permanent magnet 1 of employing, not fixedly to be bonded on magnetic conduction cleek or the sheet hook, but independently be fixed in the slot at magnetic conduction cleek 2 outside housings 4 edges, and with iron core on suction nozzle 11 keep certain distances, avoid permanent magnet field magnetization iron core as far as possible, and can play the adhesive effect magnetic conduction cleek 2.When electromagnetic valve 7 energisings, magnetic conduction cleek 2 is pushed to be held on the suction nozzle 11 on the iron core by the boosting mechanism of thread-lifting hook, and and then be magnetized into the N utmost point identical or the S utmost point by electromagnetism with permanent magnet polarity, because the polarity that the magnetic conduction cleek is magnetized into is identical with permanent magnet symmetry polarity, and repel formation thrust mutually, this moment, permanent magnet 1 played the effect that promotes magnetic conduction cleek 2.Magnetic conduction iron structure also plays the effect of magnetic loop in electromagnetic valve in addition.So only applying less current, coil can hold magnetic conduction cleek 2.When the electromagnetic valve no power, because suction nozzle 11 does not have electromagnetic field on the iron core, magnetic conduction cleek 2 is not magnetized, and very fast being sucked back by permanent magnet 1 magnetization resets.After tested: when coil electricity voltage is 12V, when electric current is 10mA, the height of this device from 0.5M freely landed, suction nozzle 11 still holds magnetic conduction cleek 2 on the electromagnetic valve iron core; Same when electromagnetic valve coil cuts off the power supply, when holding magnetic conduction cleek 2, freely land from the height of 0.5M by permanent magnet 1, permanent magnet 1 still holds magnetic conduction cleek 2, and as seen it stands the vibrations of machine fully.

Comprehensive above-mentioned technology has outstanding advantage compared with the prior art: 1) adopts permanent magnet, do not have the spring fatigue problem, and simple in structure.2) made full use of the characteristic principle of magnetic, consumed power is minimum, and electric current is also little, has eliminated the difficult problem of system's heating basically, also can reduce the volume of power supply, and further reduce production costs.3) total electromagnetic valve volume also dwindles, and helps the manufacturing that large-scale pin is counted electronic jacquard machine.
