Description

Technical Field

[0001] This invention relates to the field of diaper core production technology, specifically to a core and its production equipment. Background Technology

[0002] Disposable diapers are made of materials such as non-woven fabric, toilet paper, fluff pulp, super absorbent polymer, PE film, and elastic bands. The absorbent part in the middle of the diaper is called the core. During the production process, the diaper core is made by rolling and bonding multiple layers together using production equipment. At the same time, super absorbent polymer materials are laid in the multiple layers to absorb liquid.

[0003] Chinese patent CN209548244U discloses a diaper absorbent core with a through-flow channel on its main body. The folded portion and the upper covering layer are recessed at the position of the channel, and the folded portion is bonded to the lower covering layer. This solves the technical problems of poor absorption, easy backflow, and easy clumping and breakage in existing technologies. However, the folded portion is bonded to the lower covering layer at the channel, which can cause the superabsorbent resin to expand and block the channel after absorbing urine, affecting the second absorption.

[0004] Chinese patent CN113171231B discloses a sterile production equipment for diaper cores. Its superabsorbent polymer disinfection device seals the superabsorbent polymer material inside and heats it with a heating device while stirring it with a stirring device to sterilize the superabsorbent polymer material at high temperature. However, this disinfection method requires a long stirring time to heat the superabsorbent polymer material evenly, resulting in low disinfection efficiency. In addition, it does not have the function of grooving the superabsorbent polymer layer inside the core during core production, and cannot perform grooving processing to prevent expansion and blockage of the superabsorbent polymer layer. Summary of the Invention

[0005] To address the issue that the superabsorbent resin in the absorbent core of diapers expands and blocks channels after absorbing urine, affecting secondary absorption, and that the aforementioned aseptic production equipment for diaper cores has low sterilization efficiency for polymer materials and lacks the function of slotting the polymer layer within the core, this application provides a core and its production equipment, employing the following technical solution:

[0006] A core body includes a core body comprising a hydrophilic nonwoven fabric, a dust-free paper is adhered to the underside of the hydrophilic nonwoven fabric, and a breathable bottom film is provided on the underside of the dust-free paper. A polymer layer is laid between the dust-free paper and the breathable bottom film, and at least one material feeding groove is provided in the middle part of the polymer layer.

[0007] By adopting the above technical solution, the material trough opened in the polymer layer can prevent the polymer material from compensating for its expansion after absorbing water, thereby avoiding the blockage of the channel caused by the expansion of the polymer material after absorbing water, thus ensuring the secondary absorption of urine.

[0008] Optionally, the upper surface of the hydrophilic nonwoven fabric is embossed with a textured groove, and the inner side of the textured groove is provided with evenly arranged water-permeable holes. The upper surface of the dust-free paper is embossed with at least one liquid collection tank, and the two sides of the liquid collection tank are connected with multiple evenly arranged diversion channels.

[0009] By adopting the above technical solution, the hydrophilic nonwoven fabric can quickly disperse urine in all directions through the mesh grooves and flow downwards rapidly through the water-permeable holes, thereby greatly accelerating the absorption speed of urine. The dust-free paper collects urine through the liquid collection tank and distributes it evenly to the polymer layer through the diversion tank, thereby ensuring uniform absorption of urine.

[0010] A core production device includes a base. A vertical wall panel is fixed to the middle of the upper surface of the base. Three vertically arranged material roll racks are fixedly installed on the front side of the wall panel near the left end. The material roll racks, from top to bottom, respectively hold hydrophilic nonwoven fabric rolls, dust-free paper rolls, and breathable bottom film rolls. Two first forming rollers for imprinting the hydrophilic nonwoven fabric are installed on the front side of the wall panel near the upper end. Two second forming rollers for imprinting the dust-free paper are installed on the front side of the wall panel below the first forming rollers. A guide roller is installed on the right side of the roller to guide the hydrophilic nonwoven fabric and dust-free paper. Two pressure rollers are installed on the front side of the wall panel near the right end to press the hydrophilic nonwoven fabric, dust-free paper, polymer layer and breathable bottom film together. A fabric feeding mechanism is installed on the wall panel on the upper surface of the breathable bottom film, located to the left of the pressure roller. The fabric feeding mechanism sprays polymer material onto the upper surface of the breathable bottom film and grooves the polymer layer. A grooving roller is installed on the right side of the pressure roller to further shape the grooved part, and a support block is installed below the grooving roller to lift the core.

[0011] By adopting the above technical solution, the polymer material is sprayed onto the upper surface of the breathable bottom membrane through the fabrication mechanism and grooved into the polymer layer. After being pressed by the pressure roller, the grooved part is grooved and shaped again by the grooving roller, thereby realizing the grooving of the polymer layer and realizing the grooving process of the polymer layer to prevent expansion and blockage of the channel.

[0012] Optionally, the fabric-laying mechanism includes a spray pipe, with baffles fixed to both sides of the spray pipe near the breathable bottom membrane to block the polymer material, and at least one slotting plate fixed between the two baffles to divide and groove the sprayed polymer material. Multiple spray nozzles are fixed to the lower surface of the spray pipe. The left ends of the baffles and the slotting plate are fixedly connected by a connecting plate, and the connecting plate is fixed to the wall panel by a locking plate.

[0013] By adopting the above technical solution, the spray pipe sprays polymer materials onto the breathable bottom membrane through the spray nozzle, and the baffle prevents splashing to the outside. The grooved plate isolates the polymer materials, thereby achieving the grooving when the polymer materials are laid.

[0014] Optionally, a sterilization mechanism for disinfecting polymer materials is installed on the rear side of the wall panel, and the discharge end of the sterilization mechanism is connected to the cloth-laying mechanism through a pipe. The sterilization mechanism is detachably installed on the wall panel through a ring-shaped fixing frame. A storage box is provided on the rear side of the wall panel, and a feeding pump is connected to the storage box through a pipe. The discharge end of the feeding pump is connected to the sterilization mechanism through a pipe. A receiving tray is installed on the upper surface of the base to receive and transport the spilled polymer materials to the right, and a collection mechanism is provided on the right side of the receiving tray to send the polymer materials collected by the receiving tray into the storage box.

[0015] By adopting the above technical solution, the spilled polymer material is received by the receiving tray and sent to the collection mechanism, which then collects it and sends it to the storage bin, thereby realizing the automatic collection and recycling of the spilled polymer material and reducing the waste of resources.

[0016] Optionally, the disinfection mechanism includes a disinfection tank. The inner side of the tank has two partition plates, one upper and one lower. Between the partition plates are multiple evenly arranged dispersing tubes, each with its upper and lower ends penetrating the partition plates. The dispersing tubes are transparent glass tubes. Multiple ultraviolet lamps are also installed between the partition plates, and a heating block is placed between the partition plates to heat the dispersing tubes. A tank lid is installed at the upper end of the tank. A transmission rod is located near the upper end of the inner side of the tank. Multiple stirring rods are fixed to the lower end of the transmission rod, and a stirring motor is connected to the upper end of the transmission rod through the tank lid. A raised retaining ring is fixed to the outer side of the tank, and a discharge pipe is connected to the lower end of the tank.

[0017] By adopting the above technical solution, the disinfection mechanism uses multiple transparent dispersion tubes to uniformly disperse and transport the polymer material into the disinfection tank downwards, and uses ultraviolet lamps to uniformly and quickly irradiate and sterilize it. At the same time, the dispersion tubes are heated by heating blocks to uniformly and quickly heat the dispersed polymer material, thereby achieving efficient sterilization and disinfection of the polymer material.

[0018] Optionally, the central shafts of the two pressure rollers are fixed with drive gears through the wall panel, and a drive pulley is also fixed on the central shaft of one of the pressure rollers. The two drive gears mesh with each other, and a drive motor is fixed on one side of one of the drive gears and fixed on the wall panel. A drive gear that meshes with the drive gear is fixed on the output shaft of the drive motor. At least one annular pressure rib is fixed on the outer surface of the grooving roller, and a driven pulley is fixed on the central shaft of the grooving roller through the wall panel. The driven pulley and the drive pulley are connected by a belt.

[0019] By adopting the above technical solution, the drive motor drives two drive gears to rotate through the drive gear, thereby driving two pressure rollers to press each layer of the core. The rotation of the pressure rollers drives the rotation of the drive pulley, and through the belt drives the driven pulley to rotate, thereby driving the grooving roller to perform grooving processing.

[0020] Optionally, the receiving tray is tilted to the lower right, and multiple evenly distributed limiting rods are fixed on the lower surface of the receiving tray. The lower end of the limiting rod is fitted with a spring, and a fixing rod is inserted into the lower end of the spring. The fixing rod is fixed on the base, and a vibrator is also fixed on the lower surface of the receiving tray.

[0021] By adopting the above technical solution, the receiving tray is elastically supported by the limiting rod, fixing rod and spring, and the receiving tray is driven to vibrate by the vibrator. At this time, the receiving tray tilted to the right and downward will automatically convey the polymer material to the right.

[0022] Optionally, the collection mechanism includes a collection box, with a suction pipe inserted longitudinally on the inner side of the collection box near the right end. Multiple suction nozzles are fixed on the left side of the suction pipe. One end of the suction pipe passes through a wall panel and is connected to a suction pump. The discharge end of the suction pump is connected to a storage box through a pipe.

[0023] By adopting the above technical solution, the collection box collects polymer materials, and then the polymer materials are sucked away by the suction nozzle and suction pipe under the action of the suction pump and sent to the storage tank.

[0024] Optionally, a locking block is fixed on one side of the fixing frame, and the locking block has a slot on both the left and right sides, and an opening slot for locking the locking block is provided on the upper side of the wall panel.

[0025] By adopting the above technical solution, the fixing frame secures the disinfection tank, and the tank is detachably installed by being snapped onto the wall panel using clips.

[0026] Compared with the prior art, the beneficial effects of the present invention are:

[0027] 1. By creating a material feeding groove within the polymer layer, the polymer material will not compensate for the expansion after absorbing water, thus avoiding blockage of the channel and ensuring secondary absorption of urine.

[0028] 2. When the nozzle on the fabric mechanism sprays polymer material onto the breathable base film, the lower end of the slotted plate abuts against the upper surface of the breathable base film to block the sprayed polymer material, so that the polymer material can only cover the two sides of the slotted plate and form slots at the corresponding positions on the slotted plate. After being pressed by the pressure roller, the slotted area is pressed and shaped by the grooving roller again, thereby realizing the grooving of the polymer layer and realizing the grooving processing of the polymer layer to prevent expansion and blockage of the channels.

[0029] 3. The disinfection mechanism uses multiple transparent dispersion tubes to uniformly disperse and transport the polymer material into the disinfection tank downwards, and uses ultraviolet lamps to uniformly and quickly irradiate and sterilize it. At the same time, the heating block heats the dispersion tubes, thereby uniformly and quickly heating the dispersed polymer material to achieve efficient sterilization and disinfection of the polymer material.

[0030] 4. The spilled polymer material is collected by the receiving tray and sent to the collection mechanism, which then collects it and sends it to the storage bin, thereby realizing the automatic collection and recycling of the spilled polymer material and reducing the waste of resources.

A polymer layer 3 is laid between the dust-free paper 2 and the breathable bottom film 4, and at least one material feeding groove 31 is opened in the middle part of the polymer layer 3. The material feeding groove 31 opened in the polymer layer 3 can prevent the polymer material from making room compensation after absorbing water and expanding, thereby avoiding the blockage of the channel after the polymer material absorbs water and expands, thus ensuring the secondary absorption of urine.

[0047] Reference Figure 2 and Figure 3 As shown, the upper surface of the hydrophilic nonwoven fabric 1 is embossed with a textured groove 110, and the inner side of the textured groove 110 is provided with evenly arranged permeable holes 120. The hydrophilic nonwoven fabric 1 can quickly disperse urine in all directions through the textured groove 110 and flow downward quickly through the permeable holes 120, thereby greatly accelerating the absorption speed of urine. The upper surface of the dust-free paper 2 is embossed with at least one liquid collection groove 210, and multiple evenly arranged diversion grooves 220 are connected to both sides of the liquid collection groove 210. The dust-free paper 2 collects urine through the liquid collection groove 210 and evenly disperses it to the polymer layer 3 through the diversion grooves 220, thereby ensuring uniform absorption of urine.

[0048] Reference Figure 4As shown, a core production device includes a base 5. A vertical wall panel 6 is fixed to the middle of the upper surface of the base 5. Three vertically arranged material roll racks 20 are fixedly installed on the front side of the wall panel 6 near the left end. The multiple material roll racks 20 are respectively installed with hydrophilic nonwoven fabric rolls 17, dust-free paper rolls 18, and breathable bottom film rolls 19 from top to bottom.

After the pressure rollers 8 press the material, the grooving roller 12 is used to groove shape the grooved area, thereby achieving the grooving of the polymer layer 3 and realizing the grooving process of the polymer layer 3 to prevent expansion and blockage of the channels. A support block 10 is installed on the lower side of the grooving roller 12 to lift the core. The support block 10 cooperates with the grooving roller 12 for grooving.

[0050] Reference Figure 6As shown, the fabric-making mechanism 7 includes a spray pipe 72. Baffles 71, which block the polymer material, are fixed to both sides of the spray pipe 72 near the edges of the breathable base membrane 4. At least one slotted plate 74, which divides and grooves the sprayed polymer material, is fixed between the two baffles 71. Multiple nozzles 73 are fixed to the lower surface of the spray pipe 72. The spray pipe 72 sprays the polymer material onto the breathable base membrane 4 through the nozzles 73, and the baffles 71 prevent the material from being sprayed into the breathable base membrane 4. When the spray nozzle 73 sprays polymer material onto the breathable base film 4, the lower end of the slotted plate 74 abuts against the upper surface of the breathable base film 4 to block the sprayed polymer material, so that the polymer material can only cover the two sides of the slotted plate 74 and form slots at the corresponding positions of the slotted plate 74. The baffle 71 and the left end of the slotted plate 74 are fixedly connected by a connecting plate 76, and the connecting plate 76 is fixed to the wall panel 6 by a locking plate 75, which is fixed to the wall panel 6 by screws.

An opening slot for locking the locking block 241 is provided on the upper side of the wall panel 6. The fixing bracket 24 fixes the sterilization tank 137 and is locked onto the wall panel 6 via the locking block 241, thereby realizing the detachable installation of the sterilization tank 137.

A feed pump 23 is connected to the pipeline. The discharge end of the feed pump 23 is connected to the disinfection mechanism 13 through the pipeline. The feed pump 23 sends the polymer material in the storage box 22 to the disinfection mechanism 13 for disinfection. A receiving tray 9 is installed on the upper surface of the base 5 to receive and transport the spilled polymer material to the right. A collection mechanism 11 is set on the right side of the receiving tray 9 to send the polymer material collected by the receiving tray 9 to the storage box 22.

The collection mechanism 11 collects and sends the spilled polymer material to the storage box 22, thereby realizing the automatic collection and recycling of the spilled polymer material and reducing the waste of resources.

[0052] Reference Figure 7As shown, the disinfection mechanism 13 includes a disinfection tank 137. Two upper and lower partition plates 135 are installed inside the disinfection tank 137, and multiple evenly arranged dispersion tubes 136 are disposed between the two partition plates 135. The disinfection mechanism 13 conveys the polymer material entering the disinfection tank 137 downwards in a uniformly dispersed manner through the multiple transparent dispersion tubes 136.

The dispersion tubes 136 are transparent glass tubes, allowing ultraviolet light to penetrate and sterilize. Multiple ultraviolet lamps 134 are also disposed between the upper and lower partition plates 135, providing uniform and rapid irradiation for sterilization. A heating block 1310 is also disposed between the two partition plates 135 to heat the multiple dispersion tubes 136. The heating block 1310 heats the dispersion tubes 136, thereby uniformly and rapidly heating the dispersed polymer material, achieving efficient sterilization and disinfection of the polymer material.

Multiple stirring rods 133 are fixed at the lower end of the transmission rod 131, and the upper end of the transmission rod 131 passes through the lid 132 and is connected to a stirring motor. The stirring motor drives the stirring rods 133 through the transmission rod 131 to stir the polymer material entering the disinfection tank 137 so that it is evenly dispersed in each dispersion tube 136. A raised retaining ring 138 is fixed on the outer side of the disinfection tank 137, and a discharge pipe 139 is connected to the lower end of the disinfection tank 137.

The driven pulley 122 and the drive pulley 82 are connected by a belt. The drive motor 21 drives the two drive gears 81 to rotate through the drive gear, thereby driving the two pressure rollers 8 to press each layer of the core. The rotation of the pressure rollers 8 drives the rotation of the drive pulley 82 and drives the driven pulley 122 to rotate through the belt, thereby driving the grooving roller 12 to perform grooving processing.

At this time, the receiving tray 9 tilted to the lower right will automatically convey the polymer material to the right.

[0056] Reference Figure 11 As shown, the collection mechanism 11 includes a collection box 114, which collects polymer materials. A suction pipe 112 is longitudinally inserted into the inner side of the collection box 114 near the right end. Multiple suction nozzles 113 are fixed on the left side of the suction pipe 112. One end of the suction pipe 112 passes through the wall panel 6 and is connected to a suction pump 111. The discharge end of the suction pump 111 is connected to the storage tank 22 through a pipe. Under the action of the suction pump 111, the polymer materials are sucked away through the suction nozzles 113 and the suction pipe 112 and sent into the storage tank 22.

[0057] Working principle: When the core body absorbs urine, the hydrophilic nonwoven fabric 1 mesh groove 110 quickly disperses the urine in all directions and flows downward through the water-permeable holes 120 to the dust-free paper 2. The dust-free paper 2 collects the urine through the liquid collection tank 210 and distributes it evenly to the polymer layer 3 through the diversion tank 220. After absorbing the urine, the polymer layer 3 expands. At this time, the expanded polymer layer 3 extends towards the feeding tank 31 to reduce the expansion pressure between the polymer material particles and ensure the flow of the channels between the polymer material particles.

[0058] During the core production process, the first forming roller 15 rolls the hydrophilic nonwoven fabric 1, while the second forming roller 16 rolls the cleanroom paper 2. The hydrophilic nonwoven fabric 1 and cleanroom paper 2 are fed to the pressure roller 8 via the guide roller 14. At this time, the feeding pump 23 sends the polymer material in the storage tank 22 to the sterilization tank 137. The stirring motor drives the stirring rod 133 via the transmission rod 131 to stir the polymer material entering the sterilization tank 137, making it evenly dispersed in each dispersion tube 136. The polymer material is conveyed downward through the dispersion tube 136, and then passes through the ultraviolet lamp tube 134 and the heating block. 1310 is sterilized. After sterilization, the polymer material is sprayed onto the breathable bottom membrane 4 through the spray pipe 72 and the spray nozzle 73. The baffle 71 blocks the polymer material to prevent it from splashing outward. The slotted plate 74 isolates the polymer material and slots it. Then, the layers are pressed together by the pressure roller 8. The receiving tray 9 receives the scattered polymer material and vibrates it under the drive of the vibrator 94 to automatically send the polymer material to the collection box 114. Finally, under the action of the suction pump 111, the polymer material is sucked away through the suction nozzle 113 and the suction pipe 112 and sent to the storage box 22.
