Description
Technical field
The present invention relates to a kind of needle selecting device of controlling the textile machine jacquard, particularly relate to a kind of electronics flower pillow and drive plate thereof.
Background technology
Traditional mechanical jacquard, the device of control jacquard needle selecting is by iron cylindrical fireworks, rotating mechanism and contains porose cardboard and constitute, make control flower type cardboard with holes and need pass through programming, punching, threading, the fixing a series of loaded down with trivial details processes such as cardboard is installed that reach, because a colored type needs minimum three thousand sheets that get of cardboard amount, many hundreds of thousands that reach are opened, on average also have about five thousand sheets, if cardboard punching mistake is also just all thoroughly scrapped.Cardboard can not be placed for a long time in addition, otherwise the deliquescing of making moist can not use, and preserves cardboard and also need very big space, and management is got up very difficult, is disposable use substantially.
Another shortcoming of cardboard jacquard weave is that speed is slower, can not surpass 150 rev/mins, again rapid paper plate cracky.Weave the cost height so traditional mechanical jacquard exists, problem such as efficient is low, and man-hour is long is the major reason that industry development is weaved in restriction.
Publication number is that the Chinese invention patent of CN1580341 discloses a kind of Electronic card, comprise frame, eedles, reciprocating lever, this Electronic card contains several electromagnetism valve plates and every electromagnetism valve plate by restoring board, substrate, push pin, the bistable state needle selection electromagnetic valve of the stepped distribution of some one-tenth, flexible circuit constitutes, said bistable state needle selection electromagnetic valve is by solenoid valve seat, coil rack, coil, unshakable in one's determination, permanent magnet constitutes, have horizontal pilot hole and vertical special-shaped groove on the solenoid valve seat, one end of coil rack has block, one end has terminals, there is a through hole centre, iron core is placed in the through hole of coil rack, permanent magnet is located on the iron core, the excitation system that constitutes with permanent magnet unshakable in one's determination is fixed in the vertical special-shaped groove of solenoid valve seat, but the coil rack that is wound with coil moves with respect to the iron core easy on and off, one end of flexible circuit is fixed on the terminals of coil rack and with the lead-in wire of coil and is connected, the other end is fixed on the substrate, have on the restoring board and the corresponding through hole of eedles, push pin and constitute by a head and the needle body, its head is greater than the through hole on the restoring board, the through hole that the afterbody of pushing pin passes on the restoring board is inserted in the pilot hole of solenoid valve seat, and its head leans on mutually with the end of eedles or be mutually close.
The operation principle of the Electronic card of this patent is: reach Electronic card " porose " and " atresia " these two states with bistable state needle selection electromagnetic valve, coil is on the plastic coil skeleton of interior sky, one block is arranged on the coil rack, coil rack moves up and down along iron core, its block blocks pushes pin or does not block push pin formation " porose " or " atresia " these two states, and each coil rack all has 2 blocks of permanent magnets, 1 iron core and a solenoid valve seat.
Though this Electronic card can be realized two needle selection states of " porose " and " atresia " to a certain extent, it also has defective:
1, with in a slice Electronic card, the pairing length of pushing pin of different electromagnetic valves is different, makes the length specification of pushing pin a lot, and maintenance is extremely inconvenient, and the oversize flexible distortion of pushing pin causes stuckly, and fault increases;
2, the weight and the volume of the Electronic card body of being made up of the polylith Electronic card are big, being installed in the load that causes jacquard on the mechanical jacquard weighs, weares and teares big, the power of loss is also big, and in order to alleviate the weight of Electronic card body, coil rack generally can only adopt hollow plastic to make;
3, coil rack is being used for finishing and moving up and down by electromagnetic force, electromagnetic force must overcome the gravity and the inboard frictional force that produces that contacts with the iron core large tracts of land of coil rack of gravity of coil rack own and enamel-covered wire simultaneously, slip could make progress, so the power attenuation that the overwhelming majority is arranged causes power dissipation overcoming on the own wt;
4, the drive current of this Electronic card requires greatly, and the drive current of each electromagnetic valve need reach more than the 12mA, causes caloric value big, and each electromagnetic valve is equipped with the solenoid valve seat encirclement, is not easy heat radiation;
5, the coil rack of the interior empty plastic production distortion of when coil is switched on work for a long time, can generating heat, cause coil rack inboard stuck with iron core, thereby electromagnetic valve can not be moved up and down, cause and to realize " porose " and " atresia " state, also just produced and knitted the waste product cloth; In addition, the movement travel of coil rack is too big, causes speed soon not;
6, corresponding iron core of each coil, two permanent magnets, a solenoid valve seat, an Electronic card has 64 permanent magnets, not only the cost height, weight is big, assembling is complicated, and the trouble point is many.
