After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.

[0025] Example:

[0026] like Figures 1-4 As shown, the diaper absorbent paper spraying device includes a product conveyor belt 1, a feeding unit 2, and a spraying unit 3, wherein the feeding unit 2 and the spraying unit 3 are located on both sides of the feeding conveyor belt 21.

[0027] The feeding unit 2 comprises a feeding conveyor 21, a suction disc mechanism, a first lifting mechanism, and a first translation mechanism. The first lifting mechanism is connected with the suction disc mechanism and used to move the suction disc mechanism up and down. The first translation mechanism is connected with the first lifting mechanism and used to move the suction disc mechanism above the product conveyor 1. The suction disc mechanism comprises a first lifting plate 22 located above the feeding conveyor 21. The bottom of the first lifting plate 22 is connected with a plurality of suction discs 23. A plurality of air pumps 24 are mounted on the surface of the first lifting plate 22. The air pumps 24 are connected with the suction discs 23 through air pipes (not shown in the figure). The suction discs 23 generate suction force through the start of the air pumps 24, so that the suction discs 23 suck the water-absorbing paper. The first lifting mechanism comprises a first connecting plate 25 and a first driving part 26. The first driving part 26 is a pneumatic cylinder fixedly arranged on the first connecting plate 25. The power output end of the first driving part 26 is connected with the first lifting plate 22, so as to drive the first lifting plate 22 to move up and down, and further drive the suction discs 23 to move up and down. The first translation mechanism comprises a second driving part 27 and a first guide rail 28. The second driving part 27 is a motor. The length direction of the first guide rail 28 is perpendicular to the length direction of the product conveyor 1. The first guide rail 28 extends above the product conveyor 1. The first connecting plate 25 is connected with the first guide rail 28. The second driving part 27 is used to drive the first connecting plate 25 to move along the first guide rail 28, so that the suction discs 23 can move back and forth above the feeding conveyor 21 and the product conveyor 1.

[0028] The feeding unit 2 further comprises a cutting mechanism used to cut the water-absorbing paper. The cutting mechanism comprises a third driving part 29 and a cutting knife 210. The third driving part 29 is a pneumatic cylinder mounted on the rack. The power output end of the bottom of the third driving part 29 is connected with the cutting knife 210, so as to drive the cutting knife 210 to move up and down, and further cut the water-absorbing paper. The feeding unit 2 further comprises a tensioning mechanism. The tensioning mechanism comprises a first rotating shaft 211 connected with the rack. A tensioning roller 212 is coaxially connected with the first rotating shaft 211. The tensioning roller 212 is designed in layers. The outer ring of the tensioning roller 212 can rotate relative to the inner ring. Pressing springs 213 are arranged at both ends of the first rotating shaft 211. The pressing springs 213 press downward on the first rotating shaft 211. The top of each pressing spring 213 is provided with an adjusting rod 214 used to adjust the pressing degree. The adjusting rod 214 is screw-connected with the rack, so as to adjust the pressing degree of the pressing spring 213. The tensioning mechanism further comprises a second rotating shaft 215 rotatably connected with the rack. Resisting blocks 216 are fixedly arranged at both ends of the second rotating shaft 215. The resisting blocks 216 extend below the first rotating shaft 211. A pull rod 217 is further fixedly arranged on the second rotating shaft 215. When the pull rod 217 rotates, the resisting blocks 216 are driven to rotate, so that the first rotating shaft 211 and the tensioning roller 212 are lifted to facilitate the operator to take and place the water-absorbing paper.

[0029] The glue spraying unit 3 includes a glue spraying mechanism, a second translation mechanism, and a third translation mechanism. The second translation mechanism is connected to the glue spraying mechanism and is used to drive the glue spraying mechanism to move along the width direction of the product conveyor belt 1. The third translation mechanism is connected to the second translation mechanism and is used to drive the glue spraying mechanism to move along the length direction of the product conveyor belt 1.

[0030] The second translation mechanism includes a second connecting plate 31 and a fourth driving unit 32. The fourth driving unit 32 is a cylinder and is fixedly mounted on the second connecting plate 31. The power output end of the fourth driving unit 32 is connected to the glue spraying mechanism. The third translation mechanism includes a fifth driving unit 33 and a second guide rail 34. The fifth driving unit 33 is a motor. The second connecting plate 31 is connected to the second guide rail 34, and the fifth driving unit 33 is used to drive the second connecting plate 31 to move along the second guide rail 34.

[0031] Working principle:

[0032] Under normal production conditions, the semi-finished products being processed move along the product conveyor belt 1, and the absorbent paper is fed from the feeding conveyor belt 21.

[0033] Before feeding, the continuous absorbent paper is first cut to the required size by the cutting mechanism. Specifically, first, the pull rod 217 is pulled to raise the tension roller 212, so that the continuous absorbent paper passes under the tension roller 212 along the feeding conveyor belt 21. Then, the pull rod 217 is released, so that the tension roller 212 is pressed down.

[0034] When the absorbent paper reaches the required length through the cutting blade 210, the third drive unit 29 in the cutting mechanism drives the cutting blade 210 to move downward and cut the absorbent paper.

[0035] The first drive unit 26 in the first lifting mechanism drives the first lifting plate 22 to descend, causing the suction cup 23 mechanism on the first lifting plate 22 to descend. The suction cup 23 in the suction cup mechanism approaches the cut absorbent paper, and the air pump 24 works to generate suction force in the suction cup 23, which then holds the absorbent paper in place. The first drive unit 26 then drives the first lifting plate 22 and the suction cup 23 to rise, causing the absorbent paper to rise.

[0036] The second drive unit 27 in the first translation mechanism drives the first connecting plate 25 to move directly above the product conveyor belt 1, thereby moving the first lifting plate 22, suction cup 23, and absorbent paper to directly above the product conveyor belt 1. Then, the first drive unit 26 in the first lifting mechanism operates, causing the suction cup 23 to move downwards and place the absorbent paper on the product conveyor belt 1. At this point, the cylinder stops working, and the absorbent paper separates from the suction cup 23. Subsequently, the first lifting mechanism and the first translation mechanism move the suction cup mechanism above the loading conveyor belt 21, preparing for the next loading operation.

[0037] The product conveying belt 1 moves the water absorption paper to the working range of the glue spraying unit 3. The second translation mechanism and the third translation mechanism drive the glue spraying mechanism to move according to a preset trajectory. In the moving process, the nozzle of the glue spraying mechanism sprays glue on the water absorption paper. After the glue spraying is completed, the water absorption paper is conveyed to the next process by the product conveying belt 1.
