Description
[technical field]
The utility model relates to a kind of jacquard weave opening transmission mechanism, especially relates to a kind of transmission mechanism of large needle number jacquard weave opening, belongs to jacquard opening technical field.
[background technology]
Jacquard head completes the necessary devices of jacquard weaving as the textile machine such as Rapier looms and air-jet loom, market maintenance progressively increases at home, and the jacquard weave shedding mechanism that at present jacquard manufacturer produces generally to load pin number be the following type of 6144 pin, the longitudinal arrangement number of needle assembly mostly is 16 row or 24 row modes, and load capacity is low, parts running accuracy difference is the ubiquitous defect of existing structure.Along with market is to the increase in demand of high-grade fabric, the demand of super large flower shape fabric is also more and more large, and the jacquard (mostly being below 6144 pin numbers) of existing 16 row and 24 row can not meet the requirement of textile technology, the above type of 6144 pin is (as 8192 pins, 9216 pins, 10240 pins, 12288 pins) market demand share in continuous increase, particularly 10240 pins, the large needle number Patterning devicess such as 12288 pins, and the increase of knitting needle number is not a simple quantitative change, correspondingly to the transmission layout of mechanism itself, parts running precision, the bearing capacity of fuselage, manufacturing technology and material (comprise griffe material) and the large efficient function-driven system of line pin number (ten thousand pins) electronic jacquard machine are had higher requirement, so, develop a kind of new large needle number jacquard weave opening transmission mechanism extremely urgent.
Its transmission mechanism of sprocket wheel eccentric rod gear of existing extensive use on the market normally by being loaded on the power transmission shaft at bilateral wallboard rear portion, symmetry is loaded on a pair drive sprocket on power transmission shaft and engagement chain, the first shed open sprocket wheel, the second shed open sprocket wheel and tensioner sprocket wheel form, chain and the second shed open sprocket wheel, tensioner sprocket wheel and drive sprocket respectively in connect, because chain is also simultaneously external with the first shed open sprocket wheel, there is following weak point in this transmission mechanism:
Transmission accuracy is low: totally four the shed open sprocket wheels in wallboard both sides are driven by a power transmission shaft entirely, first shed open sprocket wheel, second shed open sprocket wheel respectively can not be excessively far away with the drive sprocket distance on rear transmission axle, the depth of jacquard fuselage is so caused to expand limitation large, the longitudinal arrangement quantity of namely griffing is restricted, when increasing jacquard weave eedle number specification, then need the length that corresponding increase is griffed, it is disadvantageously along with griffing the increase of length, list correspondingly increases the load griffed, griffe distortion greatly, production practices reflect that jacquard weaving float is many, be difficult to adapt to heavy duty, high-speed working condition runs.
In addition, wall scroll rear transmission axle designs, and jacquard operational shock is large, and stationarity is poor.
[utility model content]
The purpose of this utility model be to provide one to griffe frame warp-wise wider space is large, to load pin number many, the transmission mechanism of the large needle number jacquard weave opening that transmission layout is reasonable, transmission accuracy is high, driven loads ability is strong, the transmission mechanism of this large needle number jacquard weave opening can adapt to severe duty, good dynamic balance and to griffe distortion little.
For this reason, the utility model provides following technical scheme:
A kind of transmission mechanism of large needle number jacquard weave opening, comprise the commutator be fixed in frame, be arranged at a left side, power transmission shaft on right wallboard, be symmetrically arranged in a left side, frame is griffed near inside right wallboard, be symmetrically arranged in a left side, outer frame of griffing near outside right wallboard, and be symmetrically arranged in a left side, front reduction gear axle assembly on right wallboard and rear deceleration axle assembly, described power transmission shaft is by front, after be arranged in parallel and turn to contrary Synchronous Transmission axle and final drive shaft composition, commutator one end is connected with final drive shaft by shaft coupling, the drive sprocket that the opposite end of commutator is installed is in transmission connection by synchronization chain and the synchronous sprocket wheel being installed in Synchronous Transmission axle head, on final drive shaft, the drive sprocket of symmetrical installing is in transmission connection respectively by short closed chain and corresponding single rear deceleration sprocket wheel, each rear deboost axle two ends respectively by vertical connecting rod and adjacent inside and outside end in the same way of griffing frame hinged, on Synchronous Transmission axle, the drive sprocket of symmetrical installing is connected with corresponding single front reduction gear chain gear transmission respectively by short closed chain, each front reduction gear axle two ends respectively by vertical connecting rod and adjacent inside and outside end in the same way of griffing frame hinged.
As preferentially, above-mentioned final drive shaft is consistent with the setting height(from bottom) of Synchronous Transmission axle.
The utility model tool has the following advantages and beneficial effect:
1, the Double-axis transmission structure adopting Synchronous Transmission axle to combine with final drive shaft, for sharing jacquard weave driven loads, the driven loads of every bar power transmission shaft reduces by half, because the utility model transmission mechanism driven loads ability is strong, more adapt to the expansion (the large needle number jacquards as more than 6144 pin numbers) of jacquard needle quantity, meet the transmission needs of ten thousand pin jacquards completely;
2, power transmission shaft adopts forward and backward parallel and highly consistent Synchronous Transmission axle and final drive shaft, wherein, each drive sprocket of final drive shaft each side installing and single rear deceleration sprocket wheel are had ready conditions and are greatly shortened driving-chain, and each drive sprocket of Synchronous Transmission axle each side installing and single front reduction gear sprocket wheel are also had ready conditions and are greatly shortened driving-chain, this measure not only drives efficiently, and under the high station precision running transmission condition achieving forward and backward deceleration sprocket wheel, correspondingly improve inside and outside Griffe mechanism upper and lower reciprocating motion precision each other;
3, forward and backward parallel and turn in contrary Double-axis transmission structure, final drive shaft slows down after driving symmetrically arranged a pair sprocket wheel, and Synchronous Transmission axle drives symmetrically arranged a pair front reduction gear sprocket wheel, and under severe duty, dynamic balancing does very well;
4, before adopting power transmission shaft to combine with final drive shaft, rear parallel double-shaft driven Design theory, this is that two groups of Griffe mechanism warp-wise great depths layouts provide essence basis, so can need not increase under two groups of prerequisites of griffing length, only need in increase, outer two to griffe frame length and increase by two groups of warp-wise number of the arrangement of griffing (griffe through/longitudinal number of the arrangement upper limit can be promoted to more than 36 row by 24 row of prior art), the expansion that jacquard loads pin number can be realized, this is compared with traditional large needle number jacquard of same needle number specification, advantageously single little griffing load, griffe distortion little, jacquard weaving float is few, more heavy service can be adapted to, correspondingly, to griffe material require be expected to be reduced.
