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

By being controlled by the PLC(programmable controller) frequency control motor 101 work of power drive mechanism 10, drive 104 work (motion) of the second drive through the first drive 102 by driving belt 103, because the second drive 104 is fixed on the first main shaft 2a, 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 cooperate with transmission case 121 transmissions, therefore drive the second travelling gear 1214 that is fixed on the second main shaft 2b by the first travelling gear 1213 that is fixed on the first main shaft 2a, thereby make the direction of rotation of the second main shaft 2b opposite with the first main shaft 2a, with guarantee the on-woven fiber web upper and lower cylinder 5,6 seize on both sides by the arms under (also can claim to clamp) state mobile.

In the 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 driven 3 motions of pair of links mechanism 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 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 the second sprocket wheel 4311 drive input gear axles 431 rotations, (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 the input gear axle 431 and that be positioned at umbrella gear box 43, not shown, but can understand fully according to common practise), make 432 rotations of umbrella gear box output shaft 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 lower worm gear case 45 enters duty.Drive the second pinion 4531 that is fixed thereon by lower worm gear case the second output shaft 453, owing to the second pinion 4531 is meshed with the bottom roll gear ring 63 of aforesaid bottom roll 6, thereby by these second pinion, 4531 drive bottom rolls, 6 rotations.Again meanwhile, upper cylinder 5 also is 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, upper worm gear case power shaft 443 owing to upper worm gear case 44 is connected with worm gear case transition adapter sleeve 46 again, therefore upper worm gear case 44 is in running order, namely go up upper worm-gear case output shaft 442 rotations of worm gear case 44, drive the first pinion 4421 rotations that are fixed thereon.Because the first pinion 4421 is meshed with the upper cylinder gear ring 53 of upper cylinder 5, therefore upper cylinder 5 rotations.Under upper and lower cylinder 5,6 rotation, the 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 rotation and carrying the 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 by lower towing plate 36 simultaneously and pumps.Particularly when upper needle beam 7 moves downward, upper pricker 711 on the upper needle plate 71 passes 52 pairs of on-woven fiber webs of upper thorn pin hole on the cylinder 5 and implements thorn and close, and the lower needle beam 8 of this moment namely withdraws from lower thorn pin hole 62 on the bottom roll 6 owing to moving downward lower pricker 811 retractions that make on the lower needle plate 81.Otherwise, when upper needle beam 7 moves upward, upper pricker 711 on the upper needle plate 71 withdraws from the upper thorn pin hole 52 of cylinder 5, be in the retraction in the cylinder chamber 51, and the lower pricker 811 on the lower needle plate 81 of the lower needle beam 8 of this moment moves upward, namely stretch out 62 pairs of non-woven fibre webs enforcement of lower thorn pin hole thorn and close, so repeatedly.

In the process that above-mentioned upper and lower pricker 711,811 alternately closes on-woven fiber web thorn, thrust intrastitial moment at upper pricker 711, because the lower pricker 811 of this moment withdraws from the on-woven fiber web, therefore, the bottom roll 6 of this moment is being played the part of the effect of shelling net drum.But along with upper pricker 711 thrusts and pass the on-woven fiber web, the bottom roll 6 of this moment begins again to play a part holder net roller.Same reason when upper pricker 711 withdraws from the on-woven fiber web, then goes up cylinder 5 and is playing the part of the role who shells net drum, and thrust in on-woven fiber web in owing to lower pricker 811 this moment, and therefore, the upper cylinder 5 of this moment plays a part the holder net drum.

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