The griffe transmission mechanism comprises a griffe on the lower end of a frame, a plurality of needle lifting arms on two sides of the frame for lifting the griffe, a plurality of links for connecting the needle lifting arms, and a transmission spindle installed by means of fixing plates at two sides of the upper end of the frame, wherein the transmission spindle is provided with driving chain wheels on the inner sides of the fixing plates; the outer sides of the fixing plates are provided with driving gears; the driving chain wheels are connected with eccentric driven chain wheels by chains; the driving gears are engaged with eccentric gears; and the outer sides of the fixing plates are provided with outer side cranks coaxial with the eccentric driven chain wheels while the inner sides of the fixing plates are provided with inner side cranks coaxial with the eccentric gears. According to the griffe transmission mechanism of the electronic jacquard machine in the invention, one transmission spindle is used to drive the eccentric driven chain wheels and the eccentric gears at two sides of the frame as well as the outer side cranks and the inner side cranks to stagger by 180 degrees in order to lift or drop four needle lifting arms connected with a loom, and to drive the griffe to synchronously lift jacquard needles to sequentially move upwards to form a scissors-like warp thread opening; and the whole transmission mechanism is simple in structure, skilful in design and smooth in operation.
Description
Technical field
The present invention relates to the electronic jacquard machine mechanical part, particularly the power transmission mechanism of griffing in a kind of electronic jacquard machine.
Background technology
In field of textiles, fabric has warp and parallel braiding to form usually.On loom, must realize according to certain rules warp being divided into two-layer alternately variation up and down, the passage that formation is passed through parallel, opening just, after parallel was introduced opening, two-layer warp formed new opening according to fabric tissue method alternatively up and down position, like this repeatedly, just finish the weaving process of fabric.The warp of shedding forms and is finished by the shedding choice structure, is step most crucial in the textile technology.The shedding choice structure must adapt to the needs of modern textile diversification of varieties and long-time high-speed production, and should have simple in structure, dependable performance, easy to adjust and management characteristics with unified, simultaneously, need reach that opening is clear, opening forms requirements such as " scissors shape ", warp friction and tension force are little.This just has higher requirement to the quality that needle in the shedding choice structure is mentioned.Utilize the adhesive of electromagnetic valve to put the knitting needle that to mention and the system silk thread that connects, the steel wire heald that harness eye is arranged and back-moving spring in the existing electronic jacquard machine, to reach the purpose that forms shedding, have both above characteristics simultaneously.And the operation of alternately mentioning of knitting needle has independently transmission mechanism driving fully.
For example, Granted publication number is CN201292432Y, denomination of invention discloses a kind of needle transmission mechanism for the Chinese utility model patent of " a kind of electronic jacquard machine double-cam wheel needle lifting structure ", has used the complex combination of many groups lever, eccentric cam and connecting rod to realize the above-below direction motion one on the other of interior needle arm and outer needle arm.This transmission mechanism structure is too complicated, and system's operation stability has much room for improvement.Other prior art does not still break through too complicated technology problem of drive mechanism.
Summary of the invention
The present invention is for overcoming too complicated problems of above transmission mechanism structure, and a kind of simple in structure, handling ease, electronic jacquard machine transmission mechanism for griffe that stability is high are provided, and concrete technical scheme is as follows:
A kind of electronic jacquard machine transmission mechanism for griffe, some connecting rods of mentioning the needle arm of griffing, some connection needle arms that comprise the griffing of frame lower end, frame both sides and by the hard-wired transmission main shaft of fixed head of both sides, frame upper end; In described fixed head installed inside drive sprocket is arranged on the described transmission main shaft, in the fixed head outside driving gear is installed; Described drive sprocket is connected with the eccentric-driven sprocket wheel by chain, is engaged with eccentric gear on the described driving gear; Be provided with the outside crank with described eccentric-driven sprocket coaxiality in the described fixed head outside, be provided with the inboard crank coaxial with described eccentric gear in described fixed head inboard; Described eccentric-driven sprocket wheel, eccentric gear, outside crank and inboard crank are connected the needle arm of frame both sides respectively by connecting rod.
Further, described drive sprocket, driving gear, eccentric-driven sprocket wheel, eccentric gear, outside crank and inboard crank all are installed on the described fixed head by axle.
Further, described eccentric gear differs 180 ° with the coaxial initial deflection angle of inboard crank; Described eccentric-driven sprocket wheel differs 180 ° with the coaxial initial deflection angle of outside crank; Described outside crank is identical with the initial deflection angle of inboard crank.
Further, described needle arm is separately positioned on the both sides of frame, and each side is divided into outer needle arm and interior needle arm.
Further, described eccentric gear is connected the two ends of described outer needle arm with outside crank; Described eccentric-driven sprocket wheel is connected the two ends of described interior needle arm with inboard crank.
Further, the outer needle arm of described frame one side is mentioned identical two ends of griffing with the interior needle arm of opposite side.
When transmission main shaft is connected rotation with loom, will drives all gears and sprocket wheel and rotate synchronously, and mention the needle arm up and down by the rotation drive crank of eccentric gear and eccentric-driven sprocket wheel and crank; Because crank and the initial deflection angle of eccentric-driven sprocket wheel (or eccentric gear) of mentioning needle arm two ends differs 180 °, so can move up or down with opposite step in needle arm two ends, inside and outside needle arm dislocation just can drive and griffe and knitting needle forms the shedding of " scissors shape ".
The four tool needle arms that electronic jacquard machine transmission mechanism for griffe of the present invention drives the frame both sides by transmission main shaft eccentric-driven sprocket wheel and eccentric gear and outside crank and inboard 180 ° of liftings of crank dislocation or decline are connected with loom, and drive and to griffe to mention synchronously knitting needle and take turns doing and move upward, form " scissors shape " shedding, whole transmission mechanism is simple in structure, design is ingenious, stable.
