Description

Technical Field

[0001] The present invention relates to the technical field of diaper production, and particularly to a device for deepening the efficacy of skin-care diapers and a processing method therefor. Background Art

[0002] Diapers are commonly used daily necessities for infants, generally consisting of three main parts: a skin contact layer, an absorbent core layer, and a bottom layer. The skin contact layer closely adheres to the baby's body, enabling rapid urine penetration and effectively preventing backflow, keeping the surface of the diaper dry. The skin contact layer is basically made of non-woven fabric, and in order to ensure a dry effect, the non-woven fabric needs to be processed. Currently, it is mostly achieved through a surface coating process; surface coating is to coat a film layer on the surface of the non-woven fabric to make the non-woven fabric have a dry and skin-care effect. After the skin contact layer processed by this process comes into contact with urine, the coated film layer will gradually fall off, which is not suitable for long-term use. Especially at night, when the diaper cannot be replaced in time, the diaper that has lost the dry and skin-care effect will affect the baby's skin. Therefore, the present application provides a device for deepening the efficacy of skin-care diapers and a processing method therefor to meet the needs. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a device for deepening the efficacy of skin-care diapers and a processing method therefor to solve the problem that the existing diapers will gradually lose the dry and skin-care effect after coming into contact with urine.

[0004] To solve the above technical problem, the present invention provides the following technical solutions:

[0005] A device for deepening the efficacy of skin-care diapers and a processing method therefor, including a machine body. One side of the machine body is rotatably connected with an unwinding roller, a winding roller, a first conveying roller, and a second conveying roller. The winding roller and the first conveying roller are symmetrically arranged on one side of the machine body. The unwinding roller is arranged on one side of the machine body away from the winding roller. The second conveying roller is arranged close to the first conveying roller on one side of the machine body. The outer side of the unwinding roller is wound with non-woven fabric raw materials, and a processing component for performing atomization penetration processing on the non-woven fabric raw materials, and the processing component is connected to the machine body.

[0007] Optionally, a high-pressure atomization device is fixedly connected to one side of the machine body, and a sector-shaped atomization nozzle is communicated with one side of the high-pressure atomization device.

[0008] Optionally, a processing roller is rotatably connected to one side of the machine body, and a supporting wheel is fixedly connected to one end of the processing roller.

[0009] Optionally, a connecting frame is rotatably connected to the outer side of the supporting wheel, a positioning convex block is fixedly connected to the inner side of the connecting frame, and the positioning convex block is slidably connected to the inside of the supporting wheel.

[0010] Optionally, an arc-shaped elastic sheet is fixedly connected to the inner side of the connecting frame, and a limiting bead is fixedly connected to the inner side of the arc-shaped elastic sheet.

[0011] Optionally, a shaft rod is fixedly connected to one end of the connecting frame, and a sponge rod is rotatably connected to the outer side of the shaft rod.

[0012] Optionally, an air outlet nozzle is arranged inside the processing roller, a diversion ring is fixedly connected to the outer side of the processing roller, a fan guard is fixedly connected to one side of the machine body, and the processing roller is rotatably sleeved on the outer side of the fan guard.

[0013] Optionally, a second guiding roller is rotatably connected to one side of the machine body, the second guiding roller is symmetrically arranged with the processing roller, a second processing roller is arranged on one side of the machine body, and the second processing roller is symmetrically arranged with the first guiding roller.

[0014] Optionally, an oven is arranged on one side of the machine body, a third guiding roller is rotatably connected to one side of the machine body, and the third guiding roller is symmetrically arranged with the second processing roller.

[0015] The present invention also provides a skin-care type diaper efficacy deepening processing device and its processing method, including the following steps:

[0016] Step 1: The non-woven fabric raw material is preliminarily penetrated by the atomized functional liquid ejected by the high-pressure atomization device, and the non-woven fabric raw material is dried by the fan-shaped atomizing nozzle, so as to avoid the non-woven fabric raw material being saturated and unable to continue absorbing the functional liquid, and at the same time accelerate the penetration speed of the functional liquid;

[0017] Step 2: The non-woven fabric raw material is further penetrated by the atomized functional liquid ejected by the high-pressure atomization device again to strengthen the dry and skin-care effect of the non-woven fabric raw material, and finally dried by the oven.

[0018] Compared with the prior art, the present invention has at least the following beneficial effects:

[0019] 1. In the present invention, a high-pressure atomization device is provided, and the non-woven fabric raw material is reciprocally conveyed by a guide roller. Multiple high-pressure atomization devices are staggered on both sides of the non-woven fabric raw material. The high-pressure atomization device can atomize the functional liquid. A through groove with a "V"-shaped contour is formed on the end face of the water outlet of the fan-shaped atomizing nozzle, and a water outlet is provided inside the through groove. The contour of the water outlet is oval. Thus, the atomized functional liquid in the high-pressure atomization device can be sprayed out in a horizontal fan-shaped surface, so that the surface of the non-woven fabric raw material can be evenly sprayed with the functional liquid. Moreover, the distance between multiple fan-shaped atomizing nozzles needs to ensure that when the multiple atomizing nozzles spray water mist, the multiple water mists are seamlessly connected to avoid disconnection when the water mist contacts the non-woven fabric raw material, resulting in the phenomenon that the non-woven fabric raw material cannot be comprehensively atomized and penetrated. At the same time, by spraying the functional liquid water mist under high pressure through the high-pressure atomization device, the penetration efficiency of the functional liquid can be significantly improved, and the phenomenon of the atomized functional liquid diffusing around can be avoided. The functional liquid water mist is perpendicular to the non-woven fabric raw material, so that the functional liquid can penetrate into the non-woven fabric raw material directly with the maximum force within the allowable range. When atomizing and penetrating non-woven fabric raw materials with different thicknesses and widths, the high-pressure atomization device or the fan-shaped atomizing nozzle can be replaced according to actual needs to adjust the fan-shaped surface angle, the spraying amount, and the distance between multiple fan-shaped atomizing nozzles when the functional liquid is atomized and sprayed, so as to ensure that non-woven fabric raw materials with different widths and thicknesses can be normally atomized and penetrated, and avoid excessive damage to the non-woven fabric raw material caused by excessive impact due to an overly increased spraying pressure of the atomizing liquid. Moreover, the high-pressure atomization devices on both sides spray the functional liquid on the same surface of the non-woven fabric raw material, and this surface is the upper surface of the skin contact layer and is in direct contact with the baby's skin. By atomizing this surface multiple times, the dry and skin-care effect can be significantly improved. And because the functional liquid penetrates into the non-woven fabric raw material, the phenomenon of falling off when wet will not occur, and the skin contact layer always maintains the dry and skin-care effect.

[0020] 2. The present invention is provided with a processing roller and a sponge rod. The processing roller can guide the non-woven fabric raw material, and the processing roller is driven to rotate by a driving motor inside the machine body. When the processing roller rotates, it rotates clockwise. Since the supporting wheel is fixedly connected to one end of the processing roller, when the processing roller rotates, it drives the shaft rod to rotate synchronously through the connecting frame, so that the sponge rod contacts the non-woven fabric raw material. And because the limiting beads are limited in the limiting grooves of the supporting wheel and the arc-shaped elastic sheet is an elastic structure, after the sponge rod contacts the non-woven fabric raw material, the sponge rod is blocked, and the continuous rotation of the supporting wheel will cause the arc-shaped elastic sheet to deform, so that the limiting beads gradually disengage from the limiting grooves. By repeating the above principle, the shaft rod can stop following the supporting wheel to rotate while the sponge rod is in close contact with the non-woven fabric raw material. The sponge rod is made of sponge material and can adsorb the functional liquid remaining on the surface of the non-woven fabric raw material due to atomization. The sponge rod is in a relatively saturated state, thus avoiding adsorbing too much functional liquid from the surface of the non-woven fabric raw material. At the same time, when the non-woven fabric raw material continuously passes through the sponge rod, the functional liquid on the surface of the non-woven fabric raw material can be pushed by the sponge rod, so that it is more evenly distributed on the surface of the non-woven fabric raw material, avoiding the phenomenon that the functional liquid on the non-woven fabric raw material is too much or too little in some parts. And at the same time, by starting the drying fan inside the machine body, the drying air flow flows out from multiple air outlets through the fan guard to blow the non-woven fabric raw material, accelerating the penetration speed of the functional liquid on the surface of the non-woven fabric raw material and gradually drying the non-woven fabric raw material. Thus, when the non-woven fabric raw material is atomized and penetrated subsequently, the non-woven fabric raw material will not be in a saturated state and can continue to adsorb the functional liquid.

[0038] As Figure 1 and Figure 8As shown, an embodiment of the present invention provides a skin-care type diaper efficacy deepening processing device and its processing method, including a machine body 1. On one side of the machine body 1, a unwind roller 2, a winding roller 3, a first conveying roller 4, and a second conveying roller 5 are rotatably connected. The winding roller 3 and the first conveying roller 4 are symmetrically arranged on one side of the machine body 1. The unwind roller 2 is arranged away from the winding roller 3 on one side of the machine body 1. The second conveying roller 5 is arranged close to the first conveying roller 4 on one side of the machine body 1. A driving motor is arranged inside the machine body 1 for driving a plurality of rollers to rotate. A non-woven fabric raw material 24 is wound around the outside of the unwind roller 2. One end of the non-woven fabric raw material 24 passes through the second conveying roller 5 and the first conveying roller 4 and is wound around the outside of the winding roller 3. After the non-woven fabric raw material 24 undergoes atomization and penetration treatment, it is guided by the second conveying roller 5 and the first conveying roller 4 and wound around the outside of the winding roller 3. When on the diaper production line, the atomized non-woven fabric raw material 24 can be directly led to the next processing step without being wound around the outside of the winding roller 3. A processing component for atomizing and penetrating the non-woven fabric raw material. The processing component is connected to the machine body 1. The processing component includes a guide roller 6 rotatably connected to one side of the machine body 1. A first guide roller 7 is rotatably connected to one side of the machine body 1. The non-woven fabric raw material 24 is guided by the guide roller 6 and the first guide roller 7 so that the non-woven fabric raw material 24 is conveyed from bottom to top to the guide roller 6 and then conveyed from top to bottom after passing through the guide roller 6. The reciprocating conveying method can facilitate the subsequent deep processing of the non-woven fabric raw material 24. A high-pressure atomizing device 8 is fixedly connected to one side of the machine body 1. An atomizing device is arranged inside the machine body 1 and stores a functional liquid for improving the dryness and skin-care effects. The high-pressure atomizing device 8 is connected to the atomizing device inside the machine body 1. The atomizing device inside the machine body 1 can convey the functional liquid into the inside of the high-pressure atomizing device 8. A sector atomizing nozzle 9 is communicated and arranged on one side of the high-pressure atomizing device 8. The high-pressure atomizing device 8 can atomize the functional liquid. A through groove with a "V"-shaped contour is opened on the end face of the water outlet end of the sector atomizing nozzle 9. An outlet is arranged inside the through groove. The contour of the outlet is oval. Thus, the atomized functional liquid in the high-pressure atomizing device 8 can be sprayed out in a horizontal sector surface. The angle of the sector surface is 80°. Thus, the surface of the non-woven fabric raw material 24 can be evenly sprayed with the functional liquid. And the distance between multiple sector atomizing nozzles 9 is required. When multiple sector atomizing nozzles 9 spray water mist, the multiple water mists need to achieve seamless connection to avoid disconnection when the water mist contacts the non-woven fabric raw material 24, resulting in the phenomenon that the non-woven fabric raw material 24 cannot be fully atomized and penetrated. At the same time, by spraying the functional liquid water mist under high pressure through the high-pressure atomizing device 8, the penetration efficiency of the functional liquid can be significantly improved, and the phenomenon that the atomized functional liquid diffuses around can be avoided. The functional liquid water mist is perpendicular to the non-woven fabric raw material 24, so that the functional liquid can penetrate into the non-woven fabric raw material 24 directly with the maximum force within the allowable range. When atomizing and penetrating non-woven fabric raw materials 24 with different thicknesses and widths, the high-pressure atomizing device 8 or the sector atomizing nozzle 9 can be replaced according to actual needs.The fan-shaped angle and the amount of the functional liquid sprayed during atomization and the spacing between the multiple fan-shaped atomization nozzles 9 are adjusted to ensure that the non-woven fabric materials 24 of different widths and thicknesses can be atomized and penetrated normally, and to avoid excessive increase in the pressure of the atomized liquid spraying, which may cause the non-woven fabric material 24 to be damaged by excessive impact.

[0039] By setting the guide roller 6 and the first guide roller 7, the nonwoven fabric 24 is formed as follows. Figure 1 After the direction is set, the driving motor inside the machine body 1 is started to drive the multiple rollers to rotate, so as to transport the non-woven fabric 24. The non-woven fabric 24 is transported from bottom to top to the guide roller 6 through the guidance of the first guide roller 7 and the guide roller 6, and then transported from top to bottom after passing through the guide roller 6. At the same time, the atomizing device inside the machine body 1 is started to spray the functional liquid in an atomized state from the horizontal fan-shaped surface in the fan-shaped atomizing nozzle 9 and spray it on the surface of the non-woven fabric 24. Since each high-pressure atomizing device 8 is provided with a plurality of fan-shaped atomizing nozzles 9, the functional liquid can be evenly sprayed on the surface of the non-woven fabric 24, and on the guide roller 6, the functional liquid can be sprayed on the surface of the non-woven fabric 24. Under the guidance of the roller 6, the high-pressure atomization devices 8 on both sides spray the functional liquid on the same surface of the non-woven fabric material 24, and this surface is the upper surface of the skin contact layer and is in direct contact with the baby's skin. By atomizing this surface multiple times, the dry skin care effect can be improved, and by atomizing and spraying the same surface, the functional liquid can penetrate into the non-woven fabric material 24 in one direction, avoiding the simultaneous atomization of both sides of the non-woven fabric material 24 to cause the functional liquid penetration to be blocked, thereby improving the penetration effect of the functional liquid. Since the functional liquid penetrates into the non-woven fabric material 24, it will not fall off when it comes into contact with water, so that the skin contact layer always maintains a dry skin care effect.

[0040] like Figures 3 to 5As shown, a processing roller 10 is rotatably connected to one side of the machine body 1. The non-woven fabric raw material 24 is guided by the first guide roller 7 and the processing roller 10, so that the non-woven fabric raw material 24 is in a vertical state when being conveyed upward, which is convenient for further processing. One end of the processing roller 10 is fixedly connected with a support wheel 11. A circular ring chute is arranged on the outer wall of the support wheel 11. A connecting frame 12 is rotatably connected to the outside of the support wheel 11. The connecting frame 12 is an unclosed circular ring. A rectangular hole groove is opened at the central part of the connecting frame 12. One end of the connecting frame 12 is fixedly connected with an arc plate. A positioning convex block 13 is fixedly connected to the inner side of the connecting frame 12. The positioning convex block 13 is slidably connected in the circular ring chute of the support wheel 11. An arc-shaped elastic sheet 14 is fixedly connected to the inner side of the rectangular hole groove of the connecting frame 12. A limiting bead 15 is fixedly connected to the inner side of the arc-shaped elastic sheet 14. A plurality of limiting grooves adapted to the outer contour of the limiting bead 15 are opened on the outside of the support wheel 11. The plurality of limiting grooves are connected together in an arc transition shape, so that the limiting bead 15 can slide smoothly between the plurality of limiting grooves. One end of the arc plate of the connecting frame 12 is fixedly connected with a shaft rod 16. A sponge rod 17 is rotatably connected to the outside of the shaft rod 16. A plurality of diversion grooves are opened on the outside of the processing roller 10. The cross section of the diversion groove is triangular, which can guide the functional liquid to both ends of the diversion groove. An air outlet nozzle 18 is arranged inside the diversion groove of the processing roller 10. A diversion ring 19 is fixedly connected to the outside of the processing roller 10. An annular groove is opened inside the diversion ring 19. The annular groove is communicated with the diversion groove of the processing roller 10. Water outlet holes penetrating through to the annular groove are opened on the outer wall of the diversion ring 19. A fan guard 25 is fixedly connected to one side of the machine body 1. A drying fan is arranged inside the machine body 1. The fan guard 25 is fixedly connected with the drying fan. The fan guard 25 is a cylindrical mesh cover made of metal. When the drying fan is started to convey air flow to the fan guard 25, the air flow will flow out from a plurality of air outlet nozzles 18 through the mesh holes of the fan guard 25. The processing roller 10 is rotatably sleeved on the outside of the fan guard 25.

[0041] By setting the processing roller 10 and the sponge rod 17, the processing roller 10 can guide the non-woven fabric raw material 24, and the processing roller 10 is driven to rotate by a driving motor inside the machine body 1. When the processing roller 10 rotates, it rotates clockwise. Since the support wheel 11 is fixedly connected to one end of the processing roller 10, when the processing roller 10 rotates, it drives the shaft rod 16 to rotate synchronously through the connecting frame 12, so that the sponge rod 17 contacts the non-woven fabric raw material 24. And because the limit bead 15 is limited in the limit groove of the support wheel 11 and the arc-shaped elastic piece 14 is an elastic structure, after the sponge rod 17 contacts the non-woven fabric raw material 24, the sponge rod 17 is blocked, and the continuous rotation of the support wheel 11 will cause the arc-shaped elastic piece 14 to deform, so that the limit bead 15 gradually disengages from the limit groove. By repeating the above principle, when the shaft rod 16 stops following the support wheel 11 to rotate, the sponge rod 17 can be in close contact with the non-woven fabric raw material 24. The sponge rod 17 is made of sponge material and can adsorb the functional liquid remaining on the surface of the non-woven fabric raw material 24 due to atomization. The sponge rod 17 is in a relatively saturated state, so as to avoid adsorbing too much functional liquid from the surface of the non-woven fabric raw material 24. At the same time, when the non-woven fabric raw material 24 continues to be conveyed past the sponge rod 17, the functional liquid on the surface of the non-woven fabric raw material 24 can be pushed by the sponge rod 17 to make it more evenly distributed on the surface of the non-woven fabric raw material 24, avoiding the phenomenon that the functional liquid on the non-woven fabric raw material 24 is too much or too little locally; and at the same time, by starting the drying fan inside the machine body 1, the drying air flow passes through the fan guard 25 and flows out from multiple air outlets 18 to blow the non-woven fabric raw material 24, accelerating the penetration speed of the functional liquid on the surface of the non-woven fabric raw material 24 and gradually drying the non-woven fabric raw material 24. Thus, when the non-woven fabric raw material 24 is atomized and penetrated continuously later, the non-woven fabric raw material 24 will not be in a saturated state and can continue to adsorb the functional liquid; and because the air outlet 18 is arranged in the diversion groove of the processing roller 10 and will not directly contact the non-woven fabric raw material 24, it can avoid the functional liquid remaining on the surface of the non-woven fabric raw material 24 from flowing into the air outlet 18 and causing blockage. Since the non-woven fabric raw material 24 is in close contact with the processing roller 10, although most of the remaining functional liquid on the non-woven fabric raw material 24 is removed by the sponge rod 17, there will still be a small part of the functional liquid flowing into the diversion groove of the processing roller 10. With the accumulation of a small amount, the functional liquid will flow into the annular groove of the diversion ring 19 along the diversion groove and flow out from the water outlet hole of the diversion ring 19, avoiding the accumulation of the functional liquid.

[0042] Such as Figures 1 to 2As shown in the figure, a second guide roller 20 is rotatably connected to one side of the machine body 1. The second guide roller 20 and the processing roller 10 are symmetrically arranged. A second processing roller 21 is arranged on one side of the machine body 1. The second processing roller 21 has the same structure and shape as the processing roller 10. The second processing roller 21 and the first guide roller 7 are symmetrically arranged. Through the first guide roller 7, the processing roller 10, the second guide roller 20, and the second processing roller 21, the non-woven fabric raw material 24 conveyed upward and the non-woven fabric raw material 24 conveyed downward are vertical and parallel, and at the same time, the distance between the non-woven fabric raw materials 24 in different conveying directions is shortened. An oven 22 is arranged on one side of the machine body 1. The oven 22 is a prior art and will not be elaborated here. A third guide roller 23 is rotatably connected to one side of the machine body 1. The third guide roller 23 and the second processing roller 21 are symmetrically arranged. The third guide roller 23 and the second processing roller 21 are on the same horizontal plane, so that the non-woven fabric raw material 24 can pass through the oven 22 horizontally.

[0043] By setting the oven 22, through the first guide roller 7, the processing roller 10, the second guide roller 20, and the second processing roller 21, the non-woven fabric raw material 24 conveyed upward and the non-woven fabric raw material 24 conveyed downward are close to each other. Since the functional liquid is sprayed out by the high-pressure atomization device 8 under high pressure, and the pores of the non-woven fabric raw material 24 used for making the skin contact layer are relatively large, when the functional liquid sprayed out under high pressure contacts the non-woven fabric raw material 24, the atomized functional liquid will pass through the pores of the non-woven fabric raw material 24, and then can contact the lower surface of the non-woven fabric raw material 24 conveyed downward. The functional liquid attached to the lower surface of the non-woven fabric raw material 24 can also penetrate into the non-woven fabric raw material 24 at the same time, making the dry and skin care effects of the non-woven fabric raw material 24 more three-dimensional. And the high-pressure atomization devices 8 on both sides do not correspond to each other and are arranged in a staggered manner. And because most of the power of the penetrated functional liquid is lost and it can only adhere to the surface of the non-woven fabric raw material 24, even if it contacts the lower surface of the non-woven fabric raw material 24, it will not cause resistance to the functional liquid penetrating the upper surface and affect the normal penetration of the upper surface; the second processing roller 21 absorbs and levels the newly sprayed functional liquid again, and cooperates with the guiding of the third guide roller 23 to make the non-woven fabric raw material 24 pass through the oven 22 flatly. By starting the oven 22 to finally dry the non-woven fabric raw material 24, the non-woven fabric raw material 24 is prevented from being wet.

[0044] The present invention also provides a functional liquid applied to a skin care type diaper, comprising the following components calculated by weight:

[0045] 30 parts of wild chrysanthemum, 20 parts of honeysuckle, 15 parts of silkworm excrement, 10 parts of dandelion, 10 parts of sophora flavescens, 8 parts of forsythia, 10 parts of cortex dictamni, 10 parts of plantain seed.

[0056] In the first stage, simultaneously extract wild chrysanthemum, honeysuckle, and forsythia suspense by steam distillation method, with a material-liquid ratio of 1:12, a pressure of 0.15 MPa in the distillation kettle, collect volatile oils and decoction, and the total flavonoid transfer rate > 85%. Obtain the first-stage extract.

[0057] In the second stage, use a dynamic countercurrent extraction system for sophora flavescens and dictamnus dasycarpus, with 70% ethanol as the solvent, and perform three-stage gradient extraction (60°C → 45°C → 30°C), with the extraction concentration of matrine reaching 9.8 mg / mL. Obtain the second-stage extract.

[0058] In the third stage, use high-pressure homogenization extraction technology for excrementum bombycis mori, dandelion, and plantain seed, break the cell wall by circulating at a pressure of 40 MPa, and filter the percolate through a ceramic membrane to remove impurities, with a membrane pore size of 0.22 μm.

[0060] The functional liquid applied to the skin-care type diaper forms a broad-spectrum antibacterial barrier through the rich flavonoid compounds and volatile oil components of wild chrysanthemum, which can significantly inhibit the reproduction of eczema pathogenic bacteria such as Staphylococcus aureus. The unique chlorogenic acid can further relieve the skin burning sensation; through the synergistic effect of chlorogenic acid and forsythin in the double composite formula of honeysuckle and forsythia, it blocks the generation path of pro-inflammatory factors IL-6 and TNF-α, and quickly reduces acute eczema symptoms such as redness and exudation; through the combination of animal protein hydrolysate and plant polysaccharide of bombyx mori feces and plantain seed to form a three-dimensional moisturizing network, it adsorbs tissue fluid exudate through the osmotic pressure regulation mechanism, and forms a breathable protective film in cooperation with plantain gum to relieve friction and irritation; through dandelion, sophora flavescens, and cortex dictamni, taraxasterol combined with matrine can decompose the irritating metabolites produced by urease, and dictamnolide reduces the itching threshold by inhibiting the TRPV1 receptor, forming a triple-targeted anti-itching system, enabling the diaper to have the effect of treating eczema, with a mild formula and improving the function of the diaper.

[0061] The present invention also provides a skin-care type diaper efficacy deepening processing device and its processing method, including the following steps:

[0062] Step 1. Initially penetrate the non-woven fabric raw material 24 with the atomized functional liquid ejected by the high-pressure atomizing device 8, and blow-dry the non-woven fabric raw material 24 through the fan-shaped atomizing nozzle 9 to prevent the non-woven fabric raw material 24 from being saturated and unable to continue absorbing the functional liquid, and at the same time accelerate the penetration speed of the functional liquid.

[0063] Step 2. Further penetrate the non-woven fabric raw material 24 with the atomized functional liquid ejected by the high-pressure atomizing device 8 again to enhance the dry and skin-care effect of the non-woven fabric raw material 24, and perform final drying through the oven 22.

[0064] The working principle of the technical solution provided by the present invention is as follows:

[0065] By making the non-woven fabric raw material 24 in the shape of Figure 1After the shape is set, start the drive motor inside the machine body 1 to cause multiple rollers to rotate, thereby conveying the non-woven fabric raw material 24. At the same time, start the atomization device inside the machine body 1 to make the functional liquid spray out in a horizontal fan-shaped surface from the fan-shaped atomization nozzle 9 in an atomized state, and evenly spray it on the surface of the non-woven fabric raw material 24. Under the guidance of the guide roller 6, the high-pressure atomization devices 8 on both sides spray the functional liquid on the same surface of the non-woven fabric raw material 24, and this surface is the upper surface of the skin contact layer and is in direct contact with the baby's skin. By atomizing this surface multiple times, the dry and skin-care effect can be improved. Through the first guide roller 7, the treatment roller 10, the second guide roller 20, and the second treatment roller 21, the non-woven fabric raw material 24 conveyed upward and the non-woven fabric raw material 24 conveyed downward are brought closer to each other. Since the functional liquid is sprayed out by the high-pressure atomization of the high-pressure atomization device 8 and the non-woven fabric raw material 24 used to make the skin contact layer has larger pores, when the atomized functional liquid contacts the non-woven fabric raw material 24, the atomized functional liquid will penetrate through the pores of the non-woven fabric raw material 24 and then can contact the lower surface of the non-woven fabric raw material 24 conveyed downward. The functional liquid attached to the lower surface of the non-woven fabric raw material 24 can also penetrate into the non-woven fabric raw material 24 at the same time, making the dry and skin-care effects of the non-woven fabric raw material 24 more three-dimensional.

[0066] When the treatment roller 10 rotates clockwise, since the support wheel 11 is fixedly connected to one end of the treatment roller 10, while the treatment roller 10 rotates, it drives the shaft rod 16 to rotate synchronously through the connecting frame 12, so that the sponge rod 17 contacts the non-woven fabric raw material 24. And because the limit bead 15 is limited in the limit groove of the support wheel 11 and the arc-shaped elastic piece 14 is an elastic structure, after the sponge rod 17 contacts the non-woven fabric raw material 24, the sponge rod 17 is blocked, and the continuous rotation of the support wheel 11 will cause the arc-shaped elastic piece 14 to deform, so that the limit bead 15 gradually detaches from the limit groove. By repeating the above principle, when the shaft rod 16 stops following the support wheel 11 to rotate, the sponge rod 17 can be in close contact with the non-woven fabric raw material 24. The sponge rod 17 is made of sponge material and can adsorb the functional liquid remaining on the surface of the non-woven fabric raw material 24 due to atomization. At the same time, when the non-woven fabric raw material 24 continues to be conveyed past the sponge rod 17, the functional liquid on the surface of the non-woven fabric raw material 24 can be pushed by the sponge rod 17 to make it more evenly distributed on the surface of the non-woven fabric raw material 24, avoiding the phenomenon of too much or too little functional liquid in local areas of the non-woven fabric raw material 24; and at the same time, by starting the drying fan inside the machine body 1, the drying air flow passes through the fan shroud 25 and flows out from the plurality of air outlets 18 to blow the non-woven fabric raw material 24, accelerating the penetration speed of the functional liquid on the surface of the non-woven fabric raw material 24 and gradually drying the non-woven fabric raw material 24. Thus, when the non-woven fabric raw material 24 is atomized and penetrated subsequently, the non-woven fabric raw material 24 will not be in a saturated state and can continue to adsorb the functional liquid. Finally, the non-woven fabric raw material 24 is dried by starting the oven 22.
