DETAILED DESCRIPTION

[0024] The technical scheme in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all the other embodiments obtained by the ordinary skilled in the art without creative labor belong to the protection scope of the utility model.

[0025] Embodiment 1

[0026] Please refer to Figs. 1-3A water-absorbing paper interlayer pressing device includes two symmetrical wall panels 1 and three sets of take-up rollers 2 rotatably connected to the two wall panels and arranged vertically. The upper and lower take-up rollers 2 are wound with face paper 3, and the middle take-up roller 2 is wound with a water-absorbing interlayer 4. The water-absorbing interlayer can be made of superabsorbent polymer. Each set of take-up rollers 2 has a conveyor roller group rotatably connected to the wall panel 1 on one side below it. The conveyor roller group keeps the face paper and the water-absorbing interlayer horizontal. Specifically, the conveyor roller group includes two symmetrical first conveyor rollers 8 and two symmetrical second conveyor rollers 9. Both the first and second conveyor rollers 8 and 9 are rotatably connected to the wall panel 1. The gap between the two first conveyor rollers 8 and the gap between the two second conveyor rollers 9 are at the same horizontal plane. Because the gap between the two first conveyor rollers 8 and the gap between the two second conveyor rollers 9 are at the same horizontal plane, the face paper or water-absorbing interlayer enters through the two first conveyor rollers 8 and exits through the two second conveyor rollers 9, thus keeping the face paper or water-absorbing interlayer horizontal.

[0027] Each conveyor roller assembly has a rotating shaft 5 rotatably connected to a wall panel below it. A cam 6 is connected to the rotating shaft 5. The pressing device also includes a drive mechanism for simultaneously rotating all rotating shafts 5. Specifically, the drive mechanism includes two bearing seats 10 connected to the outer side of one of the wall panels, a transmission rod 11 rotatably connected to the two bearing seats, a first motor 12 connected to the transmission rod, a first bevel gear 13 connected to the transmission rod, and a second bevel gear 14 connected to the outer end of each rotating shaft. The first bevel gear 13 meshes with the second bevel gear 14. Controlling the first motor 12 causes the transmission rod 11 to rotate. Through the engagement of the first bevel gear 13 and the second bevel gear 14, all rotating shafts 5 are rotated. The rotating shafts 5 drive the cam 6 to rotate, thereby simultaneously shaking the face paper and absorbent layer, causing dust to fall off and fly away.

[0028] The conveyor roller assembly has a guide roller 7 rotatably connected to the wall panel on the side away from the take-up roller 2. A pressing mechanism is located on one side of the guide roller 7. One absorbent interlayer and two sheets of face paper overlap at the guide roller 7 and are then pressed together by the pressing mechanism. Specifically, the pressing mechanism includes an upper pressure roller 15 and a lower pressure roller 16 rotatably connected to the wall panel, and a second motor 17 mounted on the outside of one of the wall panels. The second motor 17 is connected to one end of the lower pressure roller 16 via a coupling. Gears 18 are connected to one end of both the upper and lower pressure rollers 15 and 16, and the two gears 18 mesh. After the two sheets of face paper and one absorbent interlayer pass through the guide roller 7 and before entering the upper and lower pressure rollers 15 and 16, the second motor 17 operates. Through the engagement of the two gears 18, it drives the upper and lower pressure rollers 15 and 16 to rotate relative to each other, thereby pressing the two sheets of face paper and one absorbent interlayer together.

[0029] The working principle of this embodiment is as follows:

[0030] Both the top and bottom take-up rollers 2 are wound with face paper 3, and the middle take-up roller 2 is wound with absorbent layer 4. The face paper 3 and absorbent layer 4 are conveyed forward. When they reach the space between the first roller 8 and the second roller 9, all cams 6 are rotated by the drive mechanism. The cams 6 cause the face paper and absorbent layer to shake up and down, which can shake off the dust on the face paper and absorbent layer without tearing them. After the two face papers and one absorbent layer pass through the conveyor roller group, they enter the guide roller 7, where they are combined into one and then enter the upper pressure roller 15 and the lower pressure roller 16, which press the two face papers and one absorbent layer together.

[0031] Example 2

[0032] Based on Embodiment 1, the pressing device further includes a dust-collecting mechanism above each conveyor roller group. The dust-collecting mechanism includes a dust-collecting hood 19 installed above each conveyor roller group, with an L-shaped dust-collecting pipe 20 connected to the dust-collecting hood 19. One end of the dust-collecting pipe 20 protrudes from one of the wall panels 1 and is connected to an exhaust fan. After the cam 6 shakes off the dust from the face paper and absorbent layer, the dust is sucked out by the dust-collecting hood 19 under the action of the exhaust fan, preventing dust from re-adhering to the face paper and absorbent layer.
