Description

Technical Field

[0001] This invention relates to the field of nursing pants manufacturing technology, specifically to an adult nursing pants production line with intelligent cutting and adjustment functions. Background Technology

[0002] As we all know, with the improvement of medical standards, the strengthening of human physique, and the extension of life expectancy, the aging population problem is becoming increasingly serious. The adult care industry will be the next booming market. However, the manufacturing process of traditional adult diapers is relatively simple. They are usually made by combining the top layer, the middle absorbent core, and the bottom layer to form a continuous cuboid shape. The crotch area is cut off by cutting tools to form the diaper body to fit the user. Different body types require different sizes of the crotch area cut off, which requires changing the corresponding mold. This also increases the difficulty of equipment operation and affects production efficiency. In addition, the mold is a consumable, which also increases production costs.

[0003] Calculations show that the waste of raw materials in the areas cut off on both sides of the crotch (depending on different sizes, the larger the size, the more waste) causes a lot of waste during mass production, keeping production costs high and making companies lack market competitiveness. In addition, the waste materials cut off are difficult to dispose of, especially the PE film material in the bottom layer, which is non-degradable or very difficult to degrade, causing irreversible damage to the environment. Summary of the Invention

[0004] The purpose of this invention is to provide an adult care pants production line with intelligent cutting and adjustment function to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: an adult care pants production line with intelligent cutting and adjustment function, comprising a composite chamber, a slitting chamber, and a high-frequency vibration welding device. The production line includes a cutting chamber, the composite chamber is located between the cutting chamber and the slitting chamber, the cutting chamber cuts the ear patch material that constitutes the ear patch, the cutting chamber composites the ear patch and the retaining wall, the composite chamber composites the outer layer, absorbent, bottom layer and retaining wall, and the slitting chamber slits the composite-formed care pants; the cutting chamber is equipped with a cutting roller group and a material distribution rail, the cutting roller group is located above the material distribution rail, the material distribution rail divides the cut trapezoidal ear patch into two rows, the material distribution rail is generally "Y" shaped, pressure plates are provided on both sides above the material distribution rail, and a high-frequency vibration welding device is installed on the pressure plate, the high-frequency vibration welding device composites the ear patch and the retaining wall. The cutting chamber cuts the ear patch material and welds the cut ear patches to the retaining wall. The laminating chamber laminates the retaining wall with the top layer and the absorbent core and bottom layer of the nursing panty with the top layer. The absorbent core is located between the bottom layer and the top layer, and the top layer is located on top of the absorbent core. The laminating chamber then laminates the top layer, absorbent core, and bottom layer with the ear patches. The slitting chamber slits the laminated nursing panty to form individual nursing panties. Compared to existing methods that use a blade to cut off the sides of the crotch area, this invention directly slits the ear patches individually, reducing material waste. This invention effectively reduces material loss and avoids material waste.

[0006] The cutting roller assembly includes an upper cutting roller and a lower adsorption roller. A main shaft is installed in the middle of both the cutting roller and the adsorption roller. A collar is concentrically installed at both ends of both the cutting roller and the adsorption roller. The collar is connected to the main shaft. Two bearings are installed at both ends of the collar. A telescopic cylinder is installed below each bearing. A first cutter is installed between the two inner telescopic cylinders on the cutting roller. A second cutter is installed between the two outer telescopic cylinders on the cutting roller. A first sheath is installed between the two inner telescopic cylinders on the adsorption roller. A second sheath is installed between the two outer telescopic cylinders on the adsorption roller. The cutting roller and the suction roller are installed in the cutting chamber via a main shaft driven by a motor. The motor does not have a power-off self-locking function. The ear patch material is located between the cutting roller and the suction roller. The suction roller uses negative pressure to adsorb the ear patch material. When the cutting size is about to be reached, the cylinder rod of the telescopic cylinder retracts and causes the first / second cutter and the first / second sheath to adhere to the cutting roller and the suction roller. The suction roller and the cutting roller drive the cutter and sheath to move. The first / second cutter and the first / second sheath are all arc-shaped structures (not shown in the figure). The first cutter is located on one side of the second cutter, and the first sheath is located on one side of the second sheath. The installation angles of the first cutter and the second cutter are opposite, and the installation angles of the first sheath and the second sheath are also opposite. The cutter and the sheath cooperate to cut the ear patch material and cut out a trapezoidal ear patch. When the first cutter needs to be attached to the adsorption roller, the telescopic cylinder connected to the first cutter actuates and directly attaches the first cutter to the adsorption roller. Simultaneously, the telescopic cylinder connected to the second cutter also actuates, pushing the second cutter away from the adsorption roller, allowing the first cutter to pass through it. After the first cutter passes through the second cutter, the second cutter returns to its original position. After the first cutter is used, it passes over the top of the adsorption roller, and the cylinder rod of the telescopic cylinder connected to the first cutter extends, causing the first cutter to return to its original position under its own weight. At this time, the first cutter is again located next to the second cutter. When the second cutter is used, it is attached to the adsorption roller by the telescopic cylinder. After use, the second cutter is located next to the first cutter, and the positions of the second and first cutters have been reversed. The position switching between the first and second cutter sheaths is similar to the position switching between the first and second cutters.

[0007] The adsorption roller has two concentric negative pressure chambers and a transfer chamber with different diameters inside. The adsorption roller has several adsorption holes, which communicate with the negative pressure chambers. The negative pressure chambers communicate with the transfer chamber, which is located outside the main shaft. The main shaft is hollow and connected to an external negative pressure device. The internal space of the main shaft communicates with the transfer chamber. A retaining ring is slidably installed in the negative pressure chamber. The retaining ring has a locking slot at its upper end and pressure-reducing grooves on both sides. When the negative pressure device adsorbs the ear patch material through the main shaft, the transfer chamber, and the negative pressure chamber, outside air enters the transfer chamber through the locking slot from the negative pressure chamber. After the ear patch material is adsorbed and cut, as the adsorption roller rotates, the ear patch coverage area gradually moves to the position of the pressure-reducing groove. The pressure-reducing groove connects the adsorption holes and the outside air, allowing the pressure in the adsorption holes to return to normal, thus facilitating the ear patch to fall off the adsorption roller. The retaining ring maintains a constant position within the adsorption roller by its own weight, ensuring the locking slot always faces upwards.

[0008] Two horizontal plates are installed in the cutting chamber. The material distribution rail is located between the two horizontal plates. The material distribution rail includes two outer rails and an inner rail. A bracket is installed on the inner side of the inner rail and is connected to the upper horizontal plate. A support plate is installed on the outer side of the outer rail and is fixed to the cutting chamber. Both the outer and inner rails are annular structures. A drive chain is installed on the inner side of the outer and inner rails. A drive motor is connected to the inner side of the drive chain. Several power shafts are connected to the outer side of the drive chain. A groove is provided on the power shaft. A connecting column is slidably installed in the groove. A connecting plate is installed on the connecting column. A pin is rotatably installed on the connecting plate. A diverting roller is rotatably installed at one end of the pin. A "T"-shaped guide groove is provided on the outer rail. A sliding groove is provided on the inner rail at the position corresponding to the guide groove. The diverting rollers on two adjacent pins are respectively located in the guide grooves of the two outer rails. The other end of the pin slides in the guide groove or sliding groove. A carrier plate is installed on the upper end of the connecting plate. The lower end face of the carrier plate contacts the outer end face of the outer and inner rails. The horizontal plate is connected to the inner rail via a bracket. The inner rail is U-shaped, and the two outer rails cooperate to form a Y-shape. The outer and inner rails together form a Y-shaped structure. The drive motor drives the power shaft via a drive chain. The power shaft has a connecting column slidably mounted on it via a groove with an arc length of π / . The connecting column is stuck in the groove and can slide axially within it. The connecting column is connected to a connecting plate, which provides support for the installation of the pin. The diverting roller moves within the guide groove. The drive chain drives the pin via the power shaft, connecting column, and connecting plate. During operation, the diverting roller moves in a directional manner under the guidance of the guide groove. Under the guidance of the guide grooves on the two outer rails, the two adjacent connecting plates are respectively brought into different motion paths, namely the two branches after the "Y" shaped fork. Driven by the connecting plates, the carrier plate achieves diversion, thereby conveying the trapezoidal ear pieces with different orientations to different positions. Driven by the drive chain, the carrier plate and the connecting plate finally converge again at the main path after the "Y" shaped convergence. Through the diversion of the ear pieces by the carrier plate, the orientation of the ear pieces is adjusted to a reasonable position, which facilitates the bonding of the ear pieces with the retaining wall.

[0009] The pressure plate is located above the two branches after the "Y"-shaped fork of the material distribution rail. One end of the pressure plate is bent upwards. Inside the cutting chamber, a guide roller is installed at one end of the material distribution rail. The upper end of the guide roller is at a higher level than the lower end of the pressure plate. The carrier plate has a hollow structure and a top plate is installed inside. A spring is installed below the top plate, and a pin is installed on the top plate. One end of the pin extends out of the carrier plate. The pin is used to help fix the position of the ear patch on the carrier plate. When the cut ear patch gradually separates from the suction roller and one end of the ear patch falls onto the carrier plate, the pin inserts into the ear patch to fix its position. When the ear patch is combined with the retaining wall, i.e., when the ear patch is below the pressure plate, the pin can be pressed into the carrier plate by the pressure plate. After the ear patch and the retaining wall are combined, the height of the guide roller is adjusted so that the height of the retaining wall with the ear patch is raised, thereby gradually separating the ear patch from the carrier plate and causing the pin to detach from the ear patch.

[0010] The carrier plate has two right-angled trapezoidal slots, within which an extension plate is slidably mounted. The extension plate is hollow and has a top plate slidably mounted on it. A pin is mounted on the top plate, and a spring is installed below it. A push-pull cylinder is installed inside the carrier plate corresponding to the position of the extension plate. The output end of the push-pull cylinder is connected to the extension plate. Each link of the drive chain has a metal plate mounted on it. An electromagnet is installed inside the lower end of the drive shaft, and the electromagnet magnetically attracts the metal plates. When different sizes of ear clips need to be cut, the extension plate extends under the push-pull cylinder, increasing the overall length of the carrier plate and allowing it to support ear clips of different lengths. As the extension plate extends on the carrier plate, the electromagnet below an adjacent carrier plate is de-energized, separating the drive shaft from the drive chain to facilitate the extension of the extension plate. After a certain set time, the de-energized electromagnet is re-energized and magnetically attracts the metal plates on the links, reconnecting them.

[0011] A counterweight is embedded at the lower end of the retaining ring. The density of the counterweight is greater than that of the retaining ring. The power shaft is made of non-metallic material.

[0012] Compared with existing technologies, the beneficial effects achieved by this invention are as follows: the cutting chamber cuts the ear patch material to form the ear patch and welds the cut ear patches to the retaining wall; the composite chamber composites the retaining wall with the top layer and composites the absorbent body and bottom layer of the nursing panty with the top layer, with the absorbent body located between the bottom layer and the top layer, and the top layer located above the absorbent body; the composite chamber composites the top layer, absorbent body, and bottom layer with the ear patch; and the slitting chamber slits the composite nursing panty to form individual nursing panties. Compared with the existing method of cutting off the two sides of the crotch area with a blade, this invention directly cuts the ear patch into individual pieces, reducing material waste. This invention has the effect of reducing material loss and avoiding material waste. Attached Figure Description

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Please see Figures 1-10The present invention provides a technical solution: an adult care pants production line with intelligent cutting and adjustment function, including a composite chamber 2, a slitting chamber 3, and a high-frequency vibration welding device. The production line includes a cutting chamber 1, and the composite chamber 2 is located between the cutting chamber 1 and the slitting chamber 3. The cutting chamber 1 cuts the ear patch material 15 that constitutes the ear patch 18, and the cutting chamber 1 composites the ear patch 18 and the retaining wall 14. The composite chamber 2 composites the outer layer, absorbent, bottom layer, and retaining wall 14. The slitting chamber 3 slits the composite-formed care pants. The cutting chamber 1 is equipped with a cutting roller group and a material distribution rail 4. The cutting roller group is located above the material distribution rail 4. The material distribution rail 4 divides the cut trapezoidal ear patch 18 into two rows. The material distribution rail 4 is Y-shaped. Pressure plates 13 are arranged on both sides above the material distribution rail 4. A high-frequency vibration welding device is installed on the pressure plates 13. The high-frequency vibration welding device composites the ear patch 18 with the retaining wall 14.

[0028] The cutting roller assembly includes a cutting roller 11 located at the top and an adsorption roller 12 located at the bottom. A main shaft 26 is installed in the middle of both the cutting roller 11 and the adsorption roller 12. A collar 22 is concentrically installed at both ends of both the cutting roller 11 and the adsorption roller 12. The collar 22 is connected to the rotating shaft of the main shaft 26. Two bearings are installed at both ends of the collar 22. A telescopic cylinder is installed below each bearing. A first cutter 23 is installed between the two inner telescopic cylinders on the cutting roller 11. A second cutter is installed between the two outer telescopic cylinders on the cutting roller 11. A first sheath 27 is installed between the two inner telescopic cylinders on the adsorption roller 12. A second sheath is installed between the two outer telescopic cylinders on the adsorption roller 12. The cutting roller 11 and the suction roller 12 are installed in the cutting chamber 1 via a main shaft 26. The main shaft 26 is driven by a motor, which does not have a power-off self-locking function. The ear-shaped material 15 is located between the cutting roller 11 and the suction roller 12. The suction roller 12 adsorbs the ear-shaped material 15 through negative pressure. When the cutting size is about to be reached, the cylinder rod of the telescopic cylinder retracts and causes the first cutter 23 / second cutter and the first blade sheath 27 / second blade sheath to adhere to the cutting roller 11 and the suction roller 12. The cutting roller 11 drives the cutting blade and the sheath to move. The first cutting blade 23 / second cutting blade and the first sheath 27 / second sheath are all arc-shaped structures. The first cutting blade 23 is located on one side of the second cutting blade, and the first sheath 27 is located on one side of the second sheath. The installation angles of the first cutting blade 23 and the second cutting blade are opposite, and the installation angles of the first sheath 27 and the second sheath are also opposite. Both the sheath and the cutting blade have blades. The cutting blade and the sheath cooperate with each other to cut the ear patch material 15 and cut out trapezoidal ear patches 18. When the first cutter 23 needs to be attached to the adsorption roller 12, the telescopic cylinder connected to the first cutter 23 actuates and directly attaches the first cutter 23 to the adsorption roller 12. Simultaneously, the telescopic cylinder connected to the second cutter also actuates, pushing the second cutter away from the adsorption roller 12, allowing the first cutter 23 to pass through it. After the first cutter 23 passes through the second cutter, the second cutter returns to its original position. After the first cutter 23 is used, having passed the top of the adsorption roller 12, the cylinder rod of the telescopic cylinder connected to the first cutter 23 extends, causing the first cutter 23 to return to its original position under its own weight. At this time, the first cutter 23 is again located next to the second cutter. When using the second cutter, it is attached to the adsorption roller 12 by the telescopic cylinder. After use, the second cutter is located next to the first cutter 23, and the positions of the second and first cutters have been interchanged. The position switching between the first sheath 27 and the second sheath is similar to the position switching between the first cutter 23 and the second cutter.

[0029] The adsorption roller 12 has two concentric negative pressure chambers 24 and a transfer chamber 25 with different diameters inside. The adsorption roller 12 has several adsorption holes that are connected to the negative pressure chambers 24 and the transfer chamber 25. The transfer chamber 25 is located outside the main shaft 26. The main shaft 26 is a hollow structure and is connected to an external negative pressure device. The internal space of the main shaft 26 is connected to the transfer chamber 25. A retaining ring 28 is slidably installed in the negative pressure chamber 24. A counterweight is embedded at the lower end of the retaining ring 28. The density of the counterweight is greater than the density of the retaining ring 28. A locking slot is provided at the upper end of the retaining ring 28. Pressure reduction grooves are provided on both sides of the retaining ring 28. When the negative pressure device uses the main shaft 26, the transfer chamber 25, and the negative pressure chamber 24 to perform negative pressure adsorption on the ear patch material 15, outside air enters the transfer chamber 25 through the bayonet from the negative pressure chamber 24. After the ear patch material 15 is adsorbed by negative pressure and cut, as the adsorption roller 12 rotates, the area covered by the ear patch 18 gradually moves to the position of the pressure relief groove. The pressure relief groove connects the adsorption hole and the outside air, allowing the pressure in the adsorption hole to return to normal, thus facilitating the ear patch 18 to fall off the adsorption roller 12. The retaining ring 28 maintains a certain state in the adsorption roller 12 by its own weight, ensuring that the bayonet always faces upward.

[0030] Two horizontal plates 21 are installed horizontally in the cutting chamber 1. The material distribution rail 4 is located between the two horizontal plates 21. The material distribution rail 4 includes two outer rails 41 and an inner rail 42. A bracket 20 is installed on the inner side of the inner rail 42 and is connected to the upper horizontal plate 21. A support plate 17 is installed on the outer side of the outer rail 41 and is fixed to the cutting chamber 1. Both the outer rail 41 and the inner rail 42 are annular structures. A drive chain is installed on the inner side of the outer rail 41 and the inner rail 42. A drive motor is connected to the inner side of the drive chain. Several power shafts 43 are connected to the outer side of the drive chain. Grooves are provided on the power shafts 43. 3 is made of non-metallic material. A connecting column 44 is slidably installed in the groove. A connecting plate 45 is installed on the connecting column 44. A pin is rotatably installed on the connecting plate 45. A diverting roller 46 is rotatably installed on one end of the pin. A "T"-shaped guide groove 47 is provided on the outer rail 41. A sliding groove is provided on the inner rail 42 at the position corresponding to the guide groove 47. The diverting rollers 46 on two adjacent pins are respectively located in the guide grooves 47 of the two outer rails 41. The other end of the pin slides in the guide groove 47 or the sliding groove. A carrier plate 19 is installed on the upper end of the connecting plate 45. The lower end face of the carrier plate 19 is in contact with the outer end face of the outer rail 41 and the inner rail 42. The horizontal plate 21 is connected to the inner rail 42 via the bracket 20. The inner rail 42 is U-shaped, and the two outer rails 41 cooperate to form a Y-shape. The outer rails 41 and the inner rails 42 cooperate to form a Y-shaped structure. The drive motor drives the power shaft 43 to move via the drive chain. The power shaft 43 has a connecting column 44 slidably installed in a groove with an arc length of 10π / 9. The connecting column 44 is stuck in the groove and can slide axially within it. The connecting column 44 is connected to a connecting plate 45, which provides support for the installation of the pin. The diverting roller 46 moves within the guide groove 47. When the drive chain drives the pin to move via the power shaft 43, the connecting column 44, and the connecting plate 45, the diverting roller 46 moves within the guide groove 47. The flow is directed by the groove 47, and the connecting column 44 slides axially in the groove, so that the connecting column 44 slides to the corresponding position. Under the guidance of the guide groove 47 on the two outer rails 41, the two adjacent connecting plates 45 are respectively brought into different motion paths, that is, the two branches after the "Y" shaped fork. Driven by the connecting plate 45, the carrier plate 19 realizes the diversion, thereby transporting the trapezoidal ear pieces 18 with different orientations to different positions. Driven by the drive chain, the carrier plate 19 and the connecting plate 45 finally converge again in the main path after the "Y" shaped convergence. Through the diversion of the ear pieces 18 by the carrier plate 19, the orientation of the ear pieces 18 is adjusted to a reasonable position, which facilitates the combination of the ear pieces 18 and the retaining wall 14.

[0031] The pressure plate 13 is located above the two branches after the Y-shaped fork of the material distribution rail 4. One end of the pressure plate 13 is bent upward. Inside the cutting chamber 1, a guide roller 16 is installed at one end of the material distribution rail 4. The upper end of the guide roller 16 is at a higher level than the lower end of the pressure plate 13. The carrier plate 19 has a hollow structure inside. A top plate is installed inside the carrier plate 19. A spring is installed below the top plate. A ejector pin 30 is installed on the top plate. One end of the ejector pin 30 extends out of the carrier plate 19.

[0032] The carrier plate 19 is provided with two right-angled trapezoidal slots, in which an extension plate 29 is slidably installed. The extension plate 29 is hollow inside and has a top plate slidably installed. A pin 30 is installed on the top plate, and a spring is installed below the top plate. A push-pull cylinder 31 is installed inside the carrier plate 19 at the position corresponding to the extension plate 29. The output end of the push-pull cylinder 31 is connected to the extension plate 29. A metal plate is installed on each link of the drive chain. An electromagnet is installed inside the lower end of the power shaft 43. The electromagnet magnetically attracts the metal plate.

[0033] The ejector pin 30 is used to help fix the position of the ear patch 18 on the carrier plate 19. When the cut ear patch 18 gradually separates from the adsorption roller 12 and one end of the ear patch 18 falls on the carrier plate 19, the ejector pin 30 is inserted into the ear patch 18 to fix the position of the ear patch 18. When the ear patch 18 is combined with the retaining wall 14, that is, when the ear patch 18 is below the pressure plate 13, the ejector pin 30 can be pressed into the carrier plate 19 by the pressure plate 13. After the ear patch 18 and the retaining wall 14 are combined, the height setting of the guide roller 16 raises the height of the retaining wall 14 with the ear patch 18, thereby gradually separating the ear patch 18 from the carrier plate 19 and causing the ejector pin 30 to detach from the ear patch 18.

[0034] When ear pads 18 of different sizes need to be cut, the extension plate 29 extends under the push of the push-pull cylinder 31, thereby extending the overall length of the carrier plate 19 and enabling the carrier plate 19 to support ear pads 18 of different lengths. When the extension plate 29 extends on the carrier plate 19, the electromagnet below the adjacent carrier plate 19 is de-energized, separating the power shaft 43 from the drive chain, facilitating the extension of the extension plate 29. After a certain set time, the de-energized electromagnet is re-energized and magnetically attracts the metal plate on the chain link, completing the reconnection.

[0035] The working principle of this invention is as follows: The cutting chamber 1 cuts the ear patch material 15 that constitutes the ear patch 18, and welds the cut ear patch 18 onto the retaining wall 14; the adsorption roller 12 adsorbs the ear patch material 15 through negative pressure, and the adsorption roller 12 pulls the ear patch material 15. When the length of the ear patch material 15 is about to reach the cutting size, the cylinder rod of the telescopic cylinder retracts and causes the first cutter 23 / second cutter and the first sheath 27 / second sheath to adhere to the cutting roller 11 and the adsorption roller 12. The adsorption roller 12 and the cutting roller 11 drive the first cutter 23 / second cutter and the first sheath 27 / second sheath to move. When the first cutter 23 needs to be adhered to the adsorption roller 12, the telescopic cylinder connected to the first cutter 23 is activated and directly adheres the first cutter 23 to the adsorption roller 12. Simultaneously, the telescopic cylinder connected to the second cutter on the adsorption roller 12 also actuates, pushing the second cutter away from the adsorption roller 12 so that the first cutter 23 can pass through it. After the first cutter 23 passes through the second cutter, the second cutter returns to its original position. After the first cutter 23 is used, having passed the top of the adsorption roller 12, the cylinder rod of the telescopic cylinder connected to the first cutter 23 extends, causing the first cutter 23 to return to its original position under its own weight. At this time, the first cutter 23 is once again located on the side of the second cutter. When using the second cutter, it adheres to the adsorption roller 12 under the action of the telescopic cylinder. After use, the second cutter is located on the side of the first cutter 23, and the positions of the second cutter and the first cutter 23 are switched. The position switching between the first sheath 27 and the second sheath is similar to the position switching between the first cutter 23 and the second cutter.

[0036] Both the sheath and the cutter have blades. The first cutter 23 / second cutter and the first sheath 27 / second sheath work together to cut the ear patch material 15 and cut out trapezoidal ear patches 18.

[0037] When cutting large-sized ear patches 18, after one end of the ear patch material 15 passes over the bayonet area, it is depressurized and desorbed at the depressurization groove, so that the ear patch material 15 is in a vertical state, making it easy for the ear patch material 15 to fall onto the carrier plate 19. After reaching the cutting size, the cutter and the sheath work together to cut the ear patch material 15.

[0038] As the cut ear patch 18 gradually separates from the adsorption roller 12, and one end of the ear patch 18 falls onto the carrier plate 19, the ejector pin 30 inserts into the ear patch 18 to fix its position. The drive motor drives the power shaft 43 via the drive chain, and the power shaft 43 drives the carrier plate 19 via the connecting column 44 and the connecting plate 45. The diverting roller 46 moves within the guide groove 47. When the drive chain drives the pin shaft via the power shaft 43, the connecting column 44, and the connecting plate 45, the diverting roller 46 moves in a directional manner under the guidance of the guide groove 47. Under the guidance of the guide groove 47 on the two outer rails 41, the two adjacent connecting plates 45 are respectively drawn into different directions. The moving path is the two branches after the "Y"-shaped fork. Driven by the connecting plate 45, the carrier plate 19 achieves diversion, thereby conveying the trapezoidal ear pads 18 with different orientations to different positions. When the ear pads 18 are combined with the retaining wall 14, that is, when the ear pads 18 are below the pressure plate 13, the ejector pin 30 can be pressed into the carrier plate 19 by the pressure plate 13. The high-frequency vibration welding device combines the ear pads 18 and the retaining wall 14. After the ear pads 18 and the retaining wall 14 are combined, the height setting of the guide roller 16 raises the height of the retaining wall 14 with the ear pads 18, thereby gradually separating the ear pads 18 from the carrier plate 19 and causing the ejector pin 30 to detach from the ear pads 18.

[0039] Driven by the drive chain, the carrier plate 19 and the connecting plate 45 eventually converge again at the main road after the "Y" shaped convergence. Through the diversion of the ear pad 18 by the carrier plate 19, the orientation of the ear pad 18 is adjusted to a reasonable position, which facilitates the combination of the ear pad 18 and the retaining wall 14.

[0040] The retainer 14 with ear patches 18 is drawn into the lamination chamber 2 for further lamination, where it is laminated with the top layer. The lamination chamber 2 laminates the retainer 14 with the top layer, and also laminates the absorbent core and bottom layer that make up the nursing panty 5 with the top layer. The absorbent core is located between the bottom layer and the top layer, and the top layer is located above the absorbent core. The lamination chamber laminates the top layer with ear patches 18, the absorbent core, and the bottom layer. The slitting chamber 3 slits the laminated nursing panty 5 to form individual nursing panties.
