[0002] Diapers are daily necessities commonly used by babies. They are a general term for diapers, diapers, and pull-up pants. Dry diapers can keep babies sleeping all night. Diapers are generally composed of three main parts: surface coating layer, absorbent core layer and base fabric. The surface coating layer fits tightly to the baby's body, which can promote rapid urine penetration and effectively prevent back seepage, keeping the surface of the diaper dry.

[0003] In the existing diaper production process, pulp and super absorbent resin (SAP) are first mixed, then demolded by vacuum roller, wrapped and compacted by crepe paper to form a core, and then the core is pressed with the bottom mold and the surface layer, and finally the diaper assembly line is completed by cutting and folding. However, in the existing production line, pulp and super absorbent resin are generally stirred by ordinary mixers. During the stirring process, due to uneven crushing by the crusher, large unbroken pulp spots exist in the mixer, making it impossible to fully mix the pulp and super absorbent resin, resulting in uneven internal density of the formed core, affecting the absorption quality of the diaper.

[0042] In order to further explain the technical solution of the present invention, the present invention is described in detail below through specific embodiments.

[0043] like Figure 1-7As shown, a CNC processing diaper production line includes a CNC mixing device 1, a core forming device 2, a hot pressing device 3 and a cutting device 4 connected in sequence. The CNC mixing device 1 fully mixes the pulp and the super absorbent resin and then conveys them to the core forming device 2. The core forming device 2 wraps the mixed materials with crepe paper and compacts them to form a core. The hot pressing device 3 cuts the core and presses the core with the bottom mold and the surface layer into a shape. Finally, the cutting device 4 cuts the shape of the diaper and cuts each diaper. Finally, the diaper is folded and uniformly conveyed and packaged by the folding device. Specifically, in order to make the pulp and super absorbent resin mix more finely and evenly, the CNC mixing device 1 includes a mixing frame 11, a crushing barrel 12, a screening barrel 13 and a mixing barrel 14. The screening barrel 13 can screen the super absorbent resin and remove the large particles of super absorbent resin in the raw material to improve the fineness of the mixture. The crushing barrel 12 crushes the raw materials and performs preliminary mixing and stirring, and the mixing barrel 14 performs secondary mixing and stirring on the raw materials. The crushing barrel 12 is arranged above the mixing barrel 14, and a feeding pipe extending into the mixing barrel 14 is arranged below the crushing barrel 12. After preliminary stirring, the raw materials in the crushing barrel 12 are transported to the mixing barrel 14 through the feeding pipe. A numerical control valve can be arranged in the feeding pipe to control the opening or closing of the feeding pipe. The screening barrel 13 is arranged on the side of the crushing barrel 12. The crushing barrel 12 is provided with a needling mechanism 15 and a first mixing mechanism 16. The first mixing mechanism 16 includes a first rotating shaft 161, a first blade 162, a rotating toothed disc 163, a driving shaft 164 and a first motor 165. The first rotating shaft 161 is arranged in the crushing barrel 12 and is rotatably connected. The driving shaft 164 and the first motor 165 are arranged on the mixing frame 11. The rotating toothed disc 163 is sleeved on the mixing barrel 14 and is rotatably connected through a bearing. The lower end of the crushing barrel 12 is fixedly connected to the rotating toothed disc 163. A driving gear 1641 is provided on the driving shaft 164. The driving gear 1641 and the rotating toothed disc 163 are meshed with each other for transmission. The first blades 162 are evenly distributed on the first rotating shaft 161. The first rotating shaft 161 and the driving shaft 164 are connected through a pulley transmission. After adopting the above structure, the screening barrel 13 conveys the screened super absorbent resin into the crushing barrel 12, and the pulp conveying device conveys the preliminarily crushed pulp into the crushing barrel 12. The first motor 165 is turned on to drive the driving shaft 164 to rotate. During the rotation of the driving shaft 164, the first rotating shaft 161 is driven to rotate in the same direction through the pulley transmission. At the same time, the driving shaft 164 drives the rotating toothed disc 163 to rotate through the driving gear 1641, thereby driving the crushing barrel 12 to rotate in the opposite direction. In this process, since the first blade 162 and the crushing barrel 12 rotate in the opposite direction, the stirring force of the first blade 162 is increased, so that the first blade 162 fully stirs the material in the crushing barrel 12, and the material mixing is more uniform and delicate.In the present embodiment, the first blade 162 is gradually inclined from top to bottom toward the rotation direction of the first rotating shaft 161. Thus, when the first blade 162 rotates with the first rotating shaft 161, the material deposited at the bottom of the crushing barrel 12 can be gradually flipped upward to avoid material deposition and thus affect the mixing efficiency, so that the material can be mixed more fully and the mixing quality of the material can be further improved.

[0044] In this embodiment, in order to improve the crushing quality of pulp, ensure that the pulp after crushing is fine, soft and fluffy, and there is no 5×5mm pulp skin point in the crushed pulp, the acupuncture mechanism 15 includes acupuncture bracket 151, a first cylinder 152, a connecting plate 153, a pressing plate 154 and acupuncture piece 155, the acupuncture bracket 151 is installed on the mixing frame 11, the first cylinder 152 is installed on the acupuncture bracket 151, the power output end of the first cylinder 152 is connected to the connecting plate 153, the first cylinder 152 is provided with four, and the first cylinder 152 is evenly distributed on the acupuncture bracket 151, to ensure that when the first cylinder 152 drives the connecting plate 153, the connecting plate 153 is lifted and lowered more smoothly. The lower end surface of the connecting plate 153 is connected to the upper end surface of the pressing plate 154 through a spring 156. The pressing plate 154 is provided with a plurality of evenly distributed through holes 1541. The needle-piercing member 155 is installed at the lower end of the connecting plate 153. Each needle-piercing member 155 corresponds to a through hole 1541. The needle-piercing member 155 can slide into the through hole 1541. The lower end of the needle-piercing member 155 is provided with a needle 1551. After adopting the above structure, while the crushing barrel 12 is mixing, the first cylinder 152 drives the connecting plate 153 and the pressing plate 154 to descend. The pressing plate 154 first contacts the material in the crushing barrel 12, which can slightly compact the material in the crushing barrel 12, ensuring that the material in the crushing barrel 12 is more compact and the mixing is more uniform and substantial. After that, the first cylinder 152 continues to drive the connecting plate 153 to descend, driving the needle-pierced member 155 to pass through the through hole 1541. The needles 1551 at the lower end of the needle-pierced member 155 can further crush the pulp on the inner surface of the crushing barrel 12, ensuring that the pulp is fully crushed, making the pulp more delicate and fluffy. Then the first cylinder 152 drives the connecting plate 153 and the pressing plate 154 to rise, and the first blade 162 stirs the material in the crushing barrel 12 and turns the bottom material upward. After that, the first cylinder 152 continues to drive the connecting plate 153 and the pressing plate 154 to descend, and repeats the above crushing action. The present invention continuously stirs the pulp in the crushing barrel 12 through the first blade 162, and the first cylinder 152 continuously drives the needle-pierced member 155 to crush the pulp in the crushing barrel 12, thereby ensuring that the pulp can be crushed more evenly, ensuring that the mixed material is more delicate and uniform, and further improving the water absorption quality of the diaper core.

[0045] In this embodiment, the screening barrel 13 includes an outer cylinder 131, an inner cylinder 132 and a swaying drive mechanism. The inner cylinder 132 is sleeved inside the outer cylinder 131. The outer cylinder 131 is provided with a guide hole. The inner cylinder 132 is provided with a guide shaft 1321 corresponding to the guide hole. The guide shaft 1321 extends into the guide hole for sliding fit. The guide shaft 1321 supports the inner cylinder 132 to ensure that the inner cylinder 132 can swing laterally inside the outer cylinder 131. A sieve plate 1322 is provided at the lower end of the inner cylinder 132. The sieve plate 1322 can filter a large volume of highly absorbent resin. A discharge pipe 1323 is provided on the side of the inner cylinder 132. The feed of the discharge pipe 1323 is provided with a baffle locked by screws. The baffle can control the discharge pipe 1323 to open or close. The discharge pipe 1323 is mainly used to vertically discharge the filtered large volume of highly absorbent resin into the screening barrel 13. A feed pipe is provided at the lower end of the outer cylinder 131. When the super absorbent resin falls into the outer cylinder 131 after screening and filtration, the screened material is input into the crushing barrel 12 along the feed pipe through a vacuum pump. The lateral swing drive mechanism drives the inner cylinder 132 to repeatedly swing laterally inside the outer cylinder 131 to ensure that the super absorbent resin can be fully shaken and screened on the screen plate 1322.

[0046] Specifically, the lateral swing drive mechanism includes a lateral shift shaft 133, a stop plate 134, a stop shaft 135 and a tension spring 136. The lateral shift shaft 133 is rotationally connected to the outer cylinder 131. One end of the lateral shift shaft 133 is connected to the stop plate 134 and the other end is rotationally connected to the drive shaft 164 via a bevel gear. The stop plate 134 is tilted, and the stop shaft 135 is disposed on the inner cylinder 132. A ball 1351 is disposed at the end of the stop shaft 135. The ball 1351 rolls and abuts against the stop plate 134. The tension spring 136 is disposed in the outer cylinder 131. The outer wall of the inner cylinder 132 is connected to the inner wall of the outer cylinder 131 via the tension spring 136. With the above structure, the driving shaft 164 can drive the first rotating shaft 161 to rotate, and can also drive the lateral shifting rotating shaft 133 to rotate. The lateral shifting rotating shaft 133 drives the abutting plate 134 to rotate during the rotation process, thereby abutting the ball 1351 and the abutting shaft 135, driving the inner cylinder 132 to move horizontally. The inner cylinder 132 repeatedly moves horizontally inside the outer cylinder 131 under the action of the tension spring 136 and the abutting plate 134. In addition, the lateral swinging driving mechanism can be directly driven by the first motor 165, which simplifies the transmission structure and further saves the equipment cost.

[0047] In this embodiment, a discharge pipe is provided at the lower end of the mixing barrel 14, and the discharge pipe is connected to the core forming device 2. The discharge pipe can transport the material in the mixing barrel 14 to the core forming device 2 through a power pump. The mixing barrel 14 is provided with a second rotating shaft 141, a second blade 142 and a second motor 143. The second rotating shaft 141 is rotatably connected to the mixing barrel 14, and the second blades 142 are evenly arranged on the second rotating shaft 141. The second motor 143 is arranged at the lower end of the mixing barrel 14, and the second motor 143 drives the second rotating shaft 141 to rotate. After adopting the above structure, the second motor 143 drives the second rotating shaft 141 to rotate, thereby driving the second blade 142 to mix the material in the mixing barrel 14 for the second time, further improving the mixing uniformity of the material.

[0048] In this embodiment, the core forming device 2 includes a vacuum drum 21, a demoulding wheel 22, a first conveyor belt 23, a side guide plate 24 and a pressure roller 25. The demoulding wheel 22 is arranged on the side of the vacuum drum 21, the first conveyor belt 23 is arranged below the demoulding wheel 22, the guide plate is symmetrically arranged above the first conveyor belt 23, and the pressure roller 25 is arranged at the discharge end of the first conveyor belt 23 and is rotatably connected to the main frame. The vacuum drum 21 and the demoulding wheel 22 are commonly used molding equipment on the market in this field, which can form a material mixed with pulp and super absorbent resin into a belt-shaped core, the conveyor belt and the traction shaft can convey the crepe paper, the demoulding wheel 22 conveys the belt-shaped core to the crepe paper, and the crepe paper is guided by the side guide plates 24 on both sides during the conveying process, so that the two sides of the crepe paper are gradually folded toward the middle, and then the core is further pressed by the pressure roller 25.

[0049] Preferably, the hot pressing device 3 comprises a second conveyor belt 31, a traction roller 32, a lifting cutter 33, a second cylinder 34, a third conveyor belt 35 and a hot pressing roller 36. The traction roller 32 is arranged at the discharge end of the first conveyor belt 23, the second conveyor belt 31 is arranged on the side of the traction roller 32, the lifting cutter 33 is arranged above the second conveyor belt 31, the second cylinder 34 drives the lifting cutter 33 to perform lifting movement, the third conveyor belt 35 is arranged at the discharge end of the second conveyor belt 31, and a plurality of groups of hot pressing rollers 36 are arranged at the discharge end of the third conveyor belt 35. The second conveyor belt 31 and the traction roller 32 convey the core body, the second cylinder 34 drives the lifting cutter 33 to cut the core body into independent core body monomers, and then conveys them to the third conveyor belt 35 through the traction roller 32, the bottom mold and the surface layer fabric are conveyed to the third conveyor belt 35 through the traction roller 32, so that the bottom mold and the surface layer fabric wrap the core body monomer, and then they are hot pressed and bonded by the hot pressing roller 36.

[0050] More preferably, in order to increase the antibacterial effect of the surface fabric, the surface fabric needs to be immersed in liquid and dried before hot pressing. The immersion mainly involves immersing the surface fabric in an antibacterial agent through an immersion device to allow the surface fabric to produce an antibacterial effect. In this embodiment, the antibacterial agent ingredients are: 0.5 parts of carboxymethyl cellulose, 2 parts of glycyrrhizic acid, 2 parts of benzethonium chloride, 3 parts of chitosan, and 30 parts of water. Glycyrrhizic acid has a strong antibacterial effect. Chitosan is a polysaccharide extracted from seaweed or animal crustaceans. It is safe, non-toxic and non-irritating. It has good antibacterial, bactericidal and anti-inflammatory effects. It is commonly found in some bandages and healing film water agents. It has a mild texture and is non-irritating. Chitosan has multiple functions such as calming the skin, improving skin resistance and repairing the skin.

[0051] Specifically, the immersion device includes an immersion box 5, a guide plate frame 6, a reeling roller 71 and a tensioning roller 72. The upper end of the immersion box 5 is provided with an exhaust pipe 51. The immersion box 5 is used to store the antibacterial agent. The side wall of the immersion box 5 is provided with a first discharge port 52. The reeling roller 71 is arranged above the immersion box 5. The tensioning roller 72 is rotatably connected to the inside of the immersion box 5. The guide plate frame 6 is provided with a guide groove 61. The guide plate frame 6 includes a horizontal cover plate 62 and a first vertical plate 63 and a second vertical plate 64 arranged on both sides of the horizontal cover plate 62. The lower surface of the horizontal cover plate 62 is supported by the upper end of the original cloth roll of the antibacterial layer. The straight plate 63 passes through the upper side wall of the immersion box 5 and is slidably connected. A sealing member is provided at the connection between the immersion box 5 and the first vertical plate 63 to ensure that the first vertical plate 63 can be sealed and matched with the immersion box 5. The second vertical plate 64 is slidably connected to the side wall of the immersion box 5. A material guide port 631 is provided at the lower end of the first vertical plate 63. A material feed port 632 is provided on the side wall of the first vertical plate 63. A second material discharge port 641 and an air inlet 642 are provided on the side wall of the second vertical plate 64. A rubber plate 65 is provided at the material feed port 632 and the second material discharge port 641. The rubber plate 65 can seal the second material discharge port 641 and the material feed port 632 while feeding and discharging the cloth. After adopting the above structure, the original cloth with the antibacterial layer is placed on the unwinding roller 71, and then the front end of the cloth enters the guide groove 61 through the feed port 632, and then enters the inside of the immersion box 5 through the guide port 631. The cloth can be wound around each tensioning roller 72 in turn to ensure that the cloth is infused with liquid for a long enough time. Finally, the cloth passes through the first discharge port 52 and the second discharge port 641 in turn for winding and recycling. During the process of the cloth being immersed in liquid, the exhaust pipe 51 is evacuated by an air pump. Since the inside of the immersion box 5 is sealed, when the air is exhausted, the external air enters the guide groove 61 through the air inlet 642, and then flows along the guide groove 61 and enters the inside of the immersion box 5 through the guide port 631. While the air flows through the second discharge port 641, the air can pass through the cloth from bottom to top, so that the antibacterial agent deposited on the lower surface of the cloth can further penetrate upward, thereby improving the liquid inlet effect of the cloth, and then further improving the antibacterial efficacy of the present invention.

[0052] Preferably, a cutter 521 is provided on the lower side wall of the first discharge port 52. When the cloth is continuously conveyed, the radius of the cloth roll gradually decreases, and at this time the horizontal cover plate 62 gradually moves downward, thereby driving the second vertical plate 64 to move downward, and when the second discharge port 641 drops to the lower end of the first discharge port 52, the cutter 521 on the first discharge port 52 can automatically cut the cloth, completing the immersion process.

[0053] Preferably, the inner side wall of the guide port 631 is provided with an inwardly protruding scraper plate 6311. The scraper plate 6311 can scrape off impurities on the upper and lower surfaces of the cloth during the process of the cloth being immersed in the liquid, so that the cloth is immersed in the liquid more fully, further improving the immersion effect.

[0054] The above embodiments and drawings do not limit the product form and style of the present invention. Any appropriate changes or modifications made by ordinary technicians in the relevant technical field should be deemed to be within the patent scope of the present invention.
