Abstract

The present invention relates to an electronic jacquard. The electronic jacquard is characterized in that a driving mechanism drives a lifting plate 31, a lifting frame 37 and a crochet hook seat frame 38 to do reciprocating movement form top to bottom so as to drive a control plate 34 to do reciprocating movement form left to right. When a magnet coil is energized, a jacquard needle 33 is lifted, and a corresponding crochet hook weaves jacquard; when the magnet coil is not energized, the corresponding crochet hook 35 does not weave jacquard. The electronic jacquard has the advantages that the action of the jacquard needle and the crochet hook is accurate and reliable, the generation of broken jacquard can be avoided, and the manufacture cost is low.

Description

Electronic jacquard machine

The present invention relates to a kind of electronic jacquard machine of producing color jacquard fabric.

Traditional jacquard adopts the mechanical type selecting mechanism, comprises card, cylindrical fireworks, eedles etc., controls the lifting of warp thread with porose on the card or atresia.Publication number is that the Chinese patent CN91104926.6 of CN1068606A discloses a kind of simple jacquard needle board, this mechanism is made up of box body, cross bar, montant, controller, spring, location-plate, restoring board, correspondence is arranged with multirow row through hole on the front and back upper and lower plates of box body, the location-plate corresponding with parallel with the every capable hole of header board is housed in the box body, the cross bar activity is in the hole of front and rear panel, the montant head is in the hole of upper and lower plates, and controller is installed in an end of the outer montant of box body.Microprocessor by designed colored type output signal, meets function that colored type needed porose and atresia state realization be equal to card thereby make to form on the header board of box body to controller.The defective of this scheme is a complex structure, and can only only substitute the function of card.

The Britain Bonus machinery Bonas Machine Company Ltd. of Co., Ltd designs a kind of broadcloth electronic jacquard machine, by frame, lifting-hook, link up with, griffe, electromagnetic valve forms, each electromagnetic valve is handled two steel lifting-hooks, lifting-hook then is connected warp thread by pulley with rope, perpendicular structure rests griffes, and follows and griffe to pump.When electronic impulse triggered electromagnetic valve, first lifting-hook and griffe to rise rested on the hook to this lifting-hook, then another lifting-hook and griffe to rise, and warp thread just is raised, and forms shed open.The defective of this scheme is that these electromagnetic valves all are discrete parts, and each electromagnetic valve must dispose two lifting-hooks and two and griffe just can make a warp thread to promote, and causes thus that this electronic jacquard machine volume is big, parts increase, cost an arm and a leg.

Publication number provides a kind of electronic jacquard machine for the Chinese patent CN96116411.5 of CN1141971A, and reasonable idea, its defective are that the knitting needle that adopts is long overweight, and the suction of electromagnet is limited, causes operational reliability not good enough, and wrong flower is difficult to avoid fully.
