Room, adsorption roller and two air-pressure chambers are connected, and air-pressure chamber is provided with aspirating hole;On feed mechanism is located in rotor and adsorption roller
Side, feed mechanism include frame in the round bar of frame, two poles for being fixedly installed in round bar, rotatable frame between two poles
Feeding roller, leave the gap passed through for paper diaper elastic layer between round bar and feeding roller.
Preferably, rotor is located at the back upper place of adsorption roller.
Preferably, adsorption roller is circumferentially divided into four regions, adsorbs the sparse rarefaction of pore size distribution and two including two
The close compact zone of absorption pore size distribution, rarefaction and compact zone interval setting.
Preferably, adsorption roller and rotor are both provided with axis, one end of their axis all stretch out frame it is outer and with it is corresponding
Driving means connect.
Preferably, the both ends of the surface of adsorption roller are distributed with the passage of circumferential arrangement, and the inner face of air-pressure chamber is provided with and leads to
The corresponding arc ventilation bar hole of pore.
Preferably, the both sides of frame are fitted with adsorption roller inner end cap and adsorption roller for installing shaft end in adsorption roller
Bearing block.
Preferably, the both sides of frame are fitted with rotor inner end cap and rotor bearing for installing shaft end in rotor
Seat.
Preferably, frame includes two pieces of side plates, header board, back plate and cover plates.
By using above-mentioned technical scheme, the invention has the beneficial effects as follows:Will be the elastic layer of paper diaper complete using rotor
Full cut-out is delivered to change straight-bar machines structure again, reduces even avoiding elastic layer in transfer and compound deviation, improve product quality and
Qualification rate, ensure that planarization and the uniform specification of full wafer elastic layer using adsorption roller as bottom roller.During elastic layer is first passed through
It is re-fed between adsorption roller and rotor between the feeding roller and round bar of top feed mechanism, elastic layer is in the portion for being attached to adsorption roller
Dividing after be cut off completely acquirement full wafer elastic layer, the front end of elastic layer fracture is still hung between adsorption roller and rotor, and inhaling
Under the suction-operated of attached roller, elastic layer fracture ensures further around the design in Suction roll surfaces, said structure with the rotation of adsorption roller
Elastic layer cut-out work is uninterruptedly carried out automatically, improve production efficiency.

Specific embodiment
The present invention is further illustrated below in conjunction with the drawings and specific embodiments.
The direction term being previously mentioned in the present invention, for example:Upper and lower, left and right, front or rear etc., are only with reference to annexed drawings
Direction.Therefore, the direction term for using is for illustrating not for limiting the present invention.
As shown in Figure 1-2, paper diaper elastic waistline shut-off mechanism, is provided with the adsorption roller of adsorption hole 24 including frame 1, side face
2nd, the rotor 3 with axial blade 34 and feed mechanism, 2 side face of adsorption roller are circumferentially divided into four regions, are distributed as Liang Ge A areas
With B areas, B areas are distributed sparse rarefaction for adsorption hole 24, and A areas are distributed close compact zone, A areas and B areas edge for adsorption hole 24
It is provided at circumferentially spaced.Frame 1 includes the back plate 12, bottom of the header board 11, rear end of the side plate 13, front end positioned at the left and right sides
Base 14, and positioned at the cover plate 15 of upper end.Rotor 3 is arranged at 2 back upper place of adsorption roller, and feed mechanism is installed on 3 He of rotor
The middle top of adsorption roller 2.
Feed mechanism includes 41, two poles 42 of round bar and feeding roller 43, and un-rotatably fixed mount is located at machine to round bar 41
Between the biside plate 13 of frame 1, two poles 42 are fixed on the middle part of round bar 41, feeding roller 43 rotationally frame in two poles 42
Between, the gap 6 passed through for paper diaper elastic layer is left between round bar 41 and feeding roller 43, under without other external force effects, paper
Urine pants elastic layer will not be skidded off from gap 6.
Adsorption roller axis 21 is carried in the middle of adsorption roller 2, and the end of adsorption roller axis 21 is by 22 He of adsorption roller inner end cap
Absorption roll bearing seat 23 is rotatably installed on the side plate of frame 1, adsorption roller inner end cap 22 and mutual of roll bearing seat 23 of absorption
The side plate 13 of frame 1 is installed on ground.The centre of rotor 3 also carries rotor axis 31, and the end of rotor axis 31 is by knife
Roller inner end cap 32 and rotor bearing block 33 are rotatably installed on the side plate of frame 1, rotor inner end cap 32 and rotor bearing block 33
It is installed on the side plate 13 of frame 1 with being mutually matched.
In this structure, the side of frame 1 is all stretched out in one end of the rotor axis 31 of the adsorption roller axis 21 and rotor 3 of adsorption roller 2
Outside plate 13, the end respectively with respective drive device(It is not shown)Connection, is driven adsorption roller 2 and rotor 3 by respective drive device
Rotate, a motor is shared by adsorption roller 2 and rotor 3 by link gear and gear structure, it is also possible to adsorption roller 2 and rotor 3
A motor is used individually.
Respectively be close to an air-pressure chamber 5 is installed in the both sides of adsorption roller 2, circle distribution is provided with two end faces of adsorption roller 2
Passage 25, be then located at arc ventilation bar hole 52,52 corresponding reality of passage 25 and ventilation bar hole in the inner side of air-pressure chamber 5
Existing adsorption roller 2 is connected with air-pressure chamber 5, and air-pressure chamber 5 is additionally provided with aspirating hole 51, aspirating hole 51 and vacuum extractor(It is not shown)
It is connected.
Paper diaper elastic layer initially passes through gap 6 and is re-fed between adsorption roller 2 and rotor 3, and the absorption elastic layer of adsorption roller 2 simultaneously draws
Dynamic elasticity layer is rotated with, and when waiting the length that elastic layer is attached to adsorption roller 2 to reach requirement, the blade 34 of rotor 3 is rotated to suction
The phase tangent line of attached roller 2 and rotor 3 simultaneously cuts off elastic layer, and the adsorption plate for becoming straight-bar machines structure 7 for being located at this shut-off mechanism front end is close to
Adsorption roller 2 so as to by full wafer elastic layer absorption go over(It is specifically shown in Fig. 3), in above process, it is close to 7 adsorption plate of straight-bar machines structure is become
The requirement for being just A areas, reducing to becoming 7 adsorption plate absorption affinity of straight-bar machines structure.After excision front end full wafer elastic layer, remaining bullet
Property layer fracture will not skid off from gap 6 and be to continue with hanging between adsorption roller 2 and rotor 3, in the suction-operated of adsorption roller 2
Under, now the position B areas corresponding with elastic layer fracture of adsorption roller 2 strengthen the absorption affinity of adsorption roller 2, and elastic layer fracture is with adsorption roller
2 rotation is around in the surface of adsorption roller 2, is then cut off by rotor 3 again and is pass by the absorption of full wafer elastic layer by straight-bar machines structure 7 is become,
So uninterruptedly repeat above-mentioned action, high working efficiency.
It is above-described, only presently preferred embodiments of the present invention, it is impossible to limit the scope that the present invention is implemented, it is every according to
Impartial change and decoration that scope of the present invention patent is made, should all still fall within the range of the present invention covers.
