Description
Technical field
The present invention relates to electronic jacquard machine mechanical part, the power transmission mechanism of particularly griffing in a kind of electronic jacquard machine.
Background technology
In field of textiles, fabric has warp and parallel braiding to form conventionally.On loom, must realize according to certain rule, by draw point, warp is divided into upper and lower two-layer alternately variation, the passage that formation is passed through parallel, opening namely, parallel is introduced after opening, and two-layer warp, according to fabric tissue method alternatively up and down position, forms new opening, repeatedly like this, just complete the weaving process of fabric.The warp of shedding forms and is completed by shedding choice structure, is step most crucial in textile technology.Shedding choice structure must adapt to the needs of modern textile diversification of varieties and long-time high-speed production, and should there is simple in structure, dependable performance, easy to adjust and manage unified feature, meanwhile, need to reach that opening is clear, opening forms the requirements such as " scissor-shaped ", warp friction and tension force are little.This just has higher requirement to the quality that in shedding choice structure, needle is mentioned.And, in existing electronic jacquard machine, utilize the adhesive of electromagnetic valve to put the integrated selecting needle assembly of the knitting needle that need to mention and the system silk thread connecting, the steel wire heald that has harness eye and back-moving spring, to reach the object that forms shedding, have both above feature simultaneously.And the operation of alternately mentioning of knitting needle has independently transmission mechanism to drive completely.
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 ", used the complex combination of many groups lever, eccentric cam and connecting rod realize in needle arm and outer needle arm moving at vertical direction one on the other.This transmission mechanism structure is too complicated, and system run all right has much room for improvement.Other prior art does not still break through the too complicated technical problem of drive mechanism.Meanwhile, because transmission mechanism is all above loom, the lubricated wet goods that must use on machine easily drops onto on the fabric of below fabric is polluted.
Summary of the invention
The present invention overcomes the too complicated and easy problem of oil dripping of above transmission mechanism structure, and a kind of simple in structure, handling ease, electronic jacquard lifting knife transmission mechanism that stability is high are provided, and concrete technical scheme is as follows:
A transmission mechanism for double-gearbox electronic jacquard machine, comprises some needle arms that mentioning of the griffing of frame lower end, frame both sides griffe, the some connecting rods that connect needle arm and by the hard-wired transmission main shaft of gear-box of both sides, frame upper end; On described transmission main shaft, in the gear-box of described both sides, driving gear is installed, in gear-box outside, drive sprocket is installed; Described driving gear is engaged with driven gear, in described gear-box inner side, the inner side sprocket wheel coaxial with described driven gear is installed, and inner side sprocket wheel is connected with inner side eccentric chain-wheel by chain; In described gear-box outside, the outside crank coaxial with described inner side eccentric chain-wheel is installed; Described drive sprocket is connected with outside eccentric chain-wheel by chain, in described gear-box inner side, the inner side crank coaxial with described outside eccentric chain-wheel is installed; Described inner side eccentric chain-wheel, outside eccentric chain-wheel, outside crank and inner side crank are connected described needle arm by connecting rod respectively.
Further, described inner side eccentric chain-wheel, outside eccentric chain-wheel, outside crank, inner side crank, drive sprocket and inner side sprocket wheel are all arranged in described frame by axle; Described driving gear and driven gear are arranged on described gear-box by axle.
Further, described outside eccentric chain-wheel differs 180 ° with the coaxial initial deflection angle of inner side crank; Described inner side eccentric chain-wheel differs 180 ° with the coaxial initial deflection angle of outside crank; Described outside crank and the initial deflection angle of inner side crank differ 180 °.
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, the outer needle arm of described frame one side and the interior needle arm of opposite side are mentioned identical two ends of griffing.
Further, described outside eccentric chain-wheel is connected the two ends of described outer needle arm with outside crank; Described inner side eccentric chain-wheel is connected the two ends of described interior needle arm with inner side crank.
Further, described driving gear and driven gear are sealed in described gear-box.
Preferably, the described knitting needle of griffing to mention is the integrated selecting needle assembly of electronic jacquard needle or draw point.
When transmission main shaft is connected rotation with loom, will drives all gears and sprocket wheel synchronous rotary, and mention up and down needle arm by the connecting rod that rotarily drives of eccentric chain-wheel and crank; Because mentioning needle arm crank and the initial deflection angle of eccentric chain-wheel differs 180 °, therefore needle arm can move up or down with contrary step, inside and outside needle arm dislocation, just can drive and griffe and knitting needle forms the shedding of " scissor-shaped ".
Electronic jacquard lifting knife transmission mechanism of the present invention is connected four tool needle arms with the inside and outside eccentric chain-wheel of loom connecting band motivation frame both sides with 180 ° of crank dislocation by a transmission main shaft, and drive and arrange griffing and arranging griffing to misplace 180 ° and synchronously mentioning knitting needle and take turns doing and move up and down of even numbers of odd number by connecting rod, form " scissor-shaped " shedding, whole transmission mechanism is simple in structure, it is ingenious, stable to design.By gear-box, seal travelling gear simultaneously, prevent that the drippage of greasy dirt from causing the pollution to fabric.
