in the time that the frequency control motor 101 of power drive mechanism 10 is worked, drive the first main shaft 2a rotation, the rotation form of first, second main shaft 2a, 2b can be referring to the superincumbent description of applicant.

applicant describes operation principle of the present invention, in Fig. 6 and Fig. 7, illustrated for on-woven fiber web capable go out work top 30, in the time will carrying out acupuncture to the on-woven fiber web by after lapping machine laying, the nonwoven webs web that comes from work top 30 is advanced between upper and lower cylinder 5,6, enter from the rear side between the upper and lower cylinder 5,6 of location status shown in Fig. 1, specific as follows:

by being controlled by PLC(programmable controller) the frequency control motor 101 of power drive mechanism 10 work, drive the second drive 104 work (motion) through the first drive 102 by driving belt 103, because the second drive 104 is fixed on the first main shaft 2a above, therefore drive the first main shaft 2a rotation (the present embodiment clockwise turns to example with the first main shaft 2a) by this second drive 104.Because first, second main shaft 2a, 2b coordinate with transmission case 121 transmissions, therefore drive by the first travelling gear 1213 being fixed on the first main shaft 2a the second travelling gear 1214 being fixed on the second main shaft 2b, thereby make the direction of rotation of the second main shaft 2b contrary with the first main shaft 2a, to ensure that on-woven fiber web moves seizing on both sides by the arms under (also can claim to clamp) state of upper and lower cylinder 5,6.

in above-mentioned course of action, because first, second connecting rod 31,32 of linkage 3 is in transmission connection with first, second main shaft 2a, 2b respectively, therefore drive pair of links mechanism 3 to move by the rotation of first, second main shaft 2a, 2b, specifically can be referring to applicant's description of linkage 3 in the above.Because aforesaid drum drive 4 and the first main shaft 2a are in transmission connection, therefore under the motion of the first main shaft 2a, drive drum drive 4 to work again.

drum drive 4 be make so aforesaid on, bottom roll 5, 6 motions, drive the first driving chain 42 by the first sprocket wheel 41 with the rotation of the first main shaft 2a, drive the second sprocket wheel 4311 by this first driving chain 42, because the second sprocket wheel 4311 is fixed on the input gear axle 431 of umbrella gear box 43, thereby second sprocket wheel 4311 drive input gear axle 431 to rotate, (be positioned at umbrella gear box by the bevel gear on the umbrella gear box output shaft 432 of bevel gear drive umbrella gear box 43 on input gear axle 431 and that be positioned at umbrella gear box 43, not shown, but can understand completely according to common practise), umbrella gear box output shaft 432 is rotated or claim motion.Because umbrella gear box output shaft 432 is in transmission connection by the lower worm gear case power shaft 454 of terminal pad and lower worm gear case 45, that is to say that lower worm gear case power shaft 454 is connected with umbrella gear box output shaft 432 by terminal pad, therefore descends worm gear case 45 to enter duty.Drive by lower worm gear case the second output shaft 453 the second pinion 4531 being fixed thereon, because the second pinion 4531 is meshed with the bottom roll gear ring 63 of aforesaid bottom roll 6, thereby drive bottom roll 6 to rotate by this second pinion 4531.Again meanwhile, upper cylinder 5 is also in rotation status, specifically: because lower worm gear case first output shaft 452 of lower worm gear case 45 is connected with worm gear case transition adapter sleeve 46, again because the upper worm gear case power shaft 443 of upper worm gear case 44 is connected with worm gear case transition adapter sleeve 46, therefore go up worm gear case 44 in running order, the upper worm-gear case output shaft 442 of going up worm gear case 44 rotates, drive the first pinion 4421 being fixed thereon to rotate.Because the first pinion 4421 is meshed with the upper cylinder gear ring 53 of upper cylinder 5, therefore go up cylinder 5 and rotate.Under the rotation of upper and lower cylinder 5,6, on-woven fiber web is moved the state of seizing on both sides by the arms is descending.

when upper and lower cylinder 5,6 rotates and carries on-woven fiber web, because linkage 3 is kept in motion, the upper towing plate 35 of reason linkage 3 drives upper needle beam 7 alternatively up and down (back and forth) motion, drives lower needle beam 8 to pump by lower towing plate 36 simultaneously.Particularly in the time that upper needle beam 7 moves downward, upper pricker on upper needle plate 71 711 is implemented thorn through the upper thorn pin hole 52 on upper cylinder 5 to on-woven fiber web and is closed, and lower needle beam 8 now exits the lower thorn pin hole 62 on bottom roll 6 owing to moving downward lower pricker 811 retractions that make on lower needle plate 81.Otherwise, in the time that upper needle beam 7 moves upward, upper pricker 711 on upper needle plate 71 exits the upper thorn pin hole 52 of cylinder 5, be in retraction in cylinder chamber 51, and lower pricker 811 on the lower needle plate 81 of lower needle beam 8 now moves upward, stretch out lower thorn pin hole 62 non-woven fibre web enforcement thorn is closed, so repeatedly.

alternately on-woven fiber web is stung in the process of closing at above-mentioned upper and lower pricker 711,811, thrust intrastitial moment at upper pricker 711, because lower pricker 811 now exits on-woven fiber web, therefore, bottom roll 6 is now being played the part of the effect of shelling net drum.But along with upper pricker 711 thrusts and pass on-woven fiber web, bottom roll 6 now starts again to play a part holder net roller.Same reason, in the time that upper pricker 711 exits on-woven fiber web, goes up cylinder 5 and is playing the part of the role who shells net drum, and now because lower pricker 811 thrusts in on-woven fiber web, therefore, upper cylinder 5 now plays a part holder net drum.

due to the diameter of upper and lower cylinder 5,6 relatively large (equal diameters of upper and lower cylinder 5,6), the space at on-woven fiber web entrance triangle place is compared with large and can meet the input that grammes per square metre is the on-woven fiber web layer that 600-1500g/ ㎡ and even grammes per square metre are larger, and this is that flat and static holder, stripping web plate in prior art cannot match in excellence or beauty.

on above-mentioned, lower needle beam 7, 8 upper, lower needle plate 71, upper on 81, lower pricker 711, 811 in regular alternatively up and down mode to by way of upper, bottom roll 5, when on-woven fiber web between 6 carries out acupuncture, swinging haulage gear 9 by aforesaid pair of links swings pair of links mechanism 3, specific as follows: because drive sprocket 91 and the second main shaft 2b of connecting rod swing haulage gear 9 fix, therefore in the process of the second main shaft 2b motion, to drive first by the second main shaft 2b through Traction Drive sprocket wheel 95 simultaneously, the second draw bar sprocket wheel 93, 94, because the first draw bar 96 is connected between lower towing plate 36 and the first draw bar sprocket wheel 93, because the second draw bar 97 is connected between upper towing plate 35 and the second draw bar sprocket wheel 94, therefore when a pair of bindiny mechanism 3 moves, swing haulage gear 9 by pair of links and make the upper of pair of links mechanism 3 again, lower towing plate 35, 36 do micro-vast swing, why claim micro-vast swing, are because upper, lower towing plate 35, 36 oscillating quantity is minimum.Because in acupuncture course, on, bottom roll 5, the 6th, roll with the speed of technique initialization, if the lower pricker 811 on the upper pricker 711 on upper needle plate 71 and lower needle plate 81 is straight up and down, so certainly go up pricker 711, lower pricker 811 can produce with upper, bottom roll wall is (on non-, lower thorn pin hole 52, 62 position) bump against and the situation that fractures, thereby by connecting rod swing haulage gear 9 drivening rod mechanisms 3, and then upper by linkage 3, lower towing plate 35, 36 drive respectively, lower needle beam 7, 8, make to be arranged on respectively, lower needle beam 7, upper on 8, lower needle plate 71, 81 with upper, bottom roll 5, 6 motion keeps constant speed movement, and in this process, under the effect of connecting rod swing haulage gear 9, make the upper pricker 711 on needle plate 71 and make lower pricker 811 on lower needle plate 81 possess the form of compound motion, under the form of this compound motion, on, lower pricker 711, 811 movement locus shows as and is similar to longitudinal elliptoid Cam Track, has avoided on the one hand, lower pricker 711, 811 respectively with upper, bottom roll 5, 6 situations that bump against, can avoid the pulling of on-woven fiber under row shifting state to draw on the other hand effectively, improve the class of on-woven product to show zero drawing-off.
