Abstract
The utility model discloses a transmission mechanism of the long distance spiral axis weft of a rapier loom, which comprises a driver, a spindle, an offset mandrel, a connecting rod, a support bar, a large spiral axis and a screw pair; the offset mandrel is fixed on the driver. One end of the connecting rod is sleeved with the offset mandrel while the other end is fixed on the sliding support, and the support bar is provided with a sliding support, one end of which has a spiral pair base; the base of the screw pair is sleeved with the large spiral axis, the two internal sides of which are respectively sleeved with a screw pair and the top of which has oil entrance holes; the two sliding areas of each screw pair closely hold the large spiral axis. The utility model makes the griper wheel, the band and the griper head move more steadily. During the operation process, the utility model has low noise, small stroke displacement, transmission accuracy and reliability, thus reducing the accumulative clearance created by the transmission and increasing the service life of the loom and improving the operation speed of the loom. The utility model has easy installation, convenient debugging, low producing cost and low maintenance cost.
Description
One, affiliated technical field:
The utility model belongs to a kind of rapier loom weft insertion transmission mechanism.
Two, background technology:
Existing rapier loom weft insertion transmission mechanism adopts connecting rod, gear, sectional wheel, bevel gear transmission, makes sword crop rotation reciprocally swinging.Its complex structure is unfavorable for maintenance; Transmission is loaded down with trivial details, the manufacturing cost height; The accumulation driving error is big, influences the service life of loom; Sword head transmission stroke is big, noise is big, influences loom speed and further improves.
Three, summary of the invention:
The utility model is exactly to solve now with the problems referred to above that exist in the technology, provide a kind of simple in structure, the transmission step is simplified, accumulate the big lead helical axis of driving error Rapier looms little, that loom speed is significantly improved wefting insertion transmission mechanism.
For addressing the above problem, technical solution of the present utility model is: the big lead helical axis of a kind of Rapier looms wefting insertion transmission mechanism, and it comprises driving wheel, main shaft, eccentric shaft, connecting rod, support bar, big lead helical axis and screw pair; Driving wheel is fixed on the main shaft, is fixed with eccentric shaft on the driving wheel, and connecting rod one end is sleeved on the eccentric shaft, and the other end is fixed on the sliding support, is with sliding support on the support bar, and sliding support one side has the screw pair base; One end of big lead helical axis is through in the sword transmission wheel; The screw pair base sheath is contained on the big lead helical axis, and both sides are set with a screw pair in it, and the upper end has fuel feed hole; Screw pair comprises that the holder of the both sides band projection that inwall is relative, the on-fixed face that is separately fixed on two projections are the slide block of the curved surface that is complementary with the curved surface of big lead helical axis, and the curved surface of two slide blocks of each screw pair is held tightly on big lead helical axis.
Eccentric shaft of the present utility model is the adjustable eccentric axle, and the one end has sliding seat, has a plurality of fixing holes on the sliding seat, and the corresponding end of driving wheel has the dovetail groove that is complementary with sliding seat, and sliding seat is inserted in the dovetail groove, is fitted in together by pressing plate and screw.The loosening position of screw adjusted sliding seat in dovetail groove, the amplitude of fluctuation that can regulate big lead helical axis is to adapt to the loom of various models.
Big lead spiral axial screw uniform pitch of the present utility model, the loom speed of the big lead helical axis of use uniform pitch spiral is higher.
The big lead helical axis transmission mechanism of the utility model design, in arrow shaft loom motion process, eccentric shaft drivening rod pulling screw pair on the driving wheel, screw pair is slided on big lead helical axis, thereby big lead helical axis is swung, make sword transmission wheel drive sword belt, sword head finish the introducing process of weft yarn.The utility model has overcome traditional arrow shaft loom and has passed in the sword motion, just can finish the shortcoming that passes the sword process by the guiding of a plurality of planetary gears and bevel gear, in use can significantly improve transmission efficiency.The advantage that the utility model is had compared with prior art is: (1) has simplified the wefting insertion drive mechanism greatly, reduced transmission link, make sword transmission wheel, sword belt, sword head weft guiding operation more steady, stroke is little, after adopting this structure, loom speed significantly improves, and especially its big lead helical axis adopts the uniform pitch spiral, improves the speed of loom more.(2) reduced transmission link, reduced the accumulation gap of causing, promoted the service life of loom, can improve the product quality of weaven goods simultaneously by transmission.(3) in operation process, noise is little, and transmission accurately, reliably.(5) it is convenient to install, debug, low cost of manufacture.(6) aborning,, consumable accessory is tailed off, greatly reduce the expense of changing consumable accessory, thereby reduce maintenance cost owing to simplified transmission link.
