The negative pressure conveyer belt 11 is provided with an independent adsorption cavity 21 at the unfolding device 14; independent absorption cavity and negative pressure conveyer belt continuously keep the negative pressure different, independent absorption cavity independently has negative-pressure air fan (not drawn) and the independent cavity that links to each other with negative-pressure air fan, this independent absorption cavity negative pressure can independently set for, when linking to each other with external control ware, when the guide board pushes forward health supplies top, independent absorption cavity shut down, when the guide board launches the flank, independent absorption cavity operation, continuously adsorb the next procedure with the flank, when avoiding the guide board to the flank to launch, the negative pressure causes the interference to the flank expansion process, lead to launching the incompleteness.

A pneumatic clamping finger 144 for adjusting the interval width of the two guide plates 141 is arranged between the guide plates 141 and the first driving device 142, and the two guide plates 141 are detachably connected with the pneumatic clamping finger 144; the pneumatic clamping fingers are conventional in the prior art and are not described in detail herein; wherein pneumatic clamp indicates the operation, and pneumatic clamp indicates that can drive two guide boards and remove to the middle part, perhaps two guide boards remove to both sides, and adjustable distance between two guide boards does benefit to the hygienic product of adaptation different specification and dimension.

The surface of the cutting device 18 is provided with a plurality of adsorption holes 16a, the middle part of the second negative pressure roller 16 is provided with an inwards concave ring surface 16b, the scraping roller 17 comprises a roller body 171, a plurality of first scraping strips 172 and second scraping strips 173 arranged on the outer side of the roller body 171, the second scraping strips 173 are positioned on two transverse sides of the first scraping strips 172, the length of the first scraping strips 172 extends into the inwards concave ring surface 16b of the second negative pressure roller 16, the length of the second scraping strips 173 is smaller than that of the first scraping strips 172, and one end, far away from the roller body 171, of the second scraping strips 173 is close to the surface of the cutting device 18; the cutting device can adsorb the surface layer of the sanitary product through the adsorption holes on the surface, the redundant part cut by the sanitary product and the surface layer are adsorbed and rotated in the rotating process of the cutting device, and the cutting device can be connected with an external waste adsorption channel when rotating to the top so as to classify and recycle materials; second negative pressure roller adsorbs rotatory in-process to the basement membrane, when carrying the rotatory downward of basement membrane, the basement membrane will paste on second negative pressure roller, the bottom is carried with the basement membrane to second negative pressure roller, the basement membrane that has the stickness is through scraping the first indent anchor ring that the strip will pass second negative pressure roller middle part of scraping on the roller, with basement membrane and second negative pressure roller separation, the second is scraped the strip and continue the rotation again with the basement membrane from second negative pressure roller with first scraping, do benefit to and strike off the core on basement membrane surface on the second negative pressure roller, can set up the recycling bin scraping the roller below, retrieve the basement membrane.

As shown in fig. 9 and 13, the pulverizing apparatus includes a frame, a pulverizing tank 201 disposed in the frame, a guiding inlet 202 disposed at the top of the pulverizing tank, a first crushing roller 203 rotatably disposed at the guiding inlet, a first motor 204 for driving the first crushing roller to rotate, a second crushing roller 205 rotatably disposed in the pulverizing tank, a screening plate 206 disposed at the bottom of the pulverizing tank, a compression spring 207 disposed between the screening plate and the pulverizing tank, a vibration motor 208 for driving the screening plate to vibrate, a polymer discharge pipe 209 disposed at one side of the bottom end of the pulverizing tank, an auger blade 210 rotatably disposed at the bottom of the discharge pipe, a wood pulp discharge pipe 211 disposed at one side of the pulverizing tank and located at the screening plate, and a second motor 212 for driving the auger blade and the second crushing roller to rotate, the first motor, the second motor, the vibration motor and the polymer discharge pipe are disposed on the frame, the vibration motor is a conventional technology, and the bottom wall 20a of the pulverizing tank 201 is inclined to the right by 3 to 8 degrees; when the core body enters the guide inlet part, the first crushing roller preliminarily crushes the core body, the crushed core body falls into the crushing tank after the crushing is finished, the core body is crushed into wood pulp, the wood pulp is brushed out from the wood pulp under the high-speed rotation of the second crushing roller and falls onto the screening plate, and the polymer in the wood pulp falls onto the bottom wall of the crushing tank through the screening plate with the screen holes, so that the screening efficiency is improved by the vibration of the vibrating motor, and the defect that the screening efficiency is low due to blockage caused by accumulation of the polymer and the wood pulp on the top of the screening plate is avoided; the polymer is from the wood pulp internal separation back, adsorbs away through the wood pulp discharging pipe of right-hand member, and in the polymer falls to crushing jar diapire and slides right the polymer discharging pipe, the auger blade of polymer discharging pipe bottom was rotatory, discharges from the bottom right-hand member, through with the cooperation of recovery line, promotes wood pulp and polymer recycle ratio.
