Description

Technical Field

[0001] The invention relates to the field of sanitary products, in particular to an absorbent article layer stacking device for diapers. Background Art

[0002] Diapers are currently widely used as sanitary products. The internal absorption layer of the diaper is the core layer and directly absorbs moisture. However, in actual use of diapers, in order to improve the comfort of use, the absorption layer needs to be adjusted.

[0003] According to CN104546299B, a molding device for producing anti-break diapers has a reasonable structural design and a compact layout. By forming two sets of molding feeding mechanisms, suction mechanisms, and conveying mechanisms into two staggered absorbent bodies, the finished product produced by the invention will not break or bulge after absorbing liquid, has fast flow diversion, and has a larger liquid receiving area.

[0004] However, in the prior art, diapers are formed by overlapping different functional layers to form an integrated structure, but the integrated structure has some problems. First, the water absorption capacity is limited. Since diapers need to be worn directly on the body, when diapers absorb a large amount of water, the diapers will expand rapidly and the overall weight will increase. If the diapers are designed to have a high water absorption capacity, the diapers after absorbing water will be larger in size and heavier in weight, which will cause greater discomfort. For the sake of comfort, diapers that have not been fully absorbed will be directly replaced, increasing the cost of use. Second, under the condition of meeting comfort requirements, diapers with insufficient water absorption capacity are designed. When used by adults who are inconvenient to exercise, diapers with limited water absorption capacity are difficult to meet the needs of adults.

[0005] To this end, the present invention provides an absorbent article layer stacking device for diapers. Summary of the invention

[0006] In order to make up for the shortcomings of the prior art and solve the problem that diapers are formed by overlapping different functional layers to form an integrated structure, but the integrated structure has a fixed water absorption capacity and poor wearing comfort after absorbing water, the present invention proposes an absorbent article layer stacking device for diapers.

[0007] The technical solution adopted by the present invention to solve the technical problem is as follows: the absorbent article layer stacking device for diapers described in the present invention comprises a machine body and a stacking roller, wherein the interior of the machine body is rotatably connected with a first conveying shaft; the number of the first conveying shafts is two and they are symmetrically arranged; the surfaces of the two first conveying shafts are both connected with a composite layer; the interior of the machine body is rotatably connected with a second conveying shaft between the two first conveying shafts; the number of the second conveying shafts is two; the surfaces of the two conveying shafts are both connected with an absorbent layer; the interior of the machine body is rotatably connected with a stacking roller; the number of the stacking rollers is two; When working, in the prior art, diapers are formed by stacking different functional layers together to form an integrated structure, but the integrated structure has some problems. First, the water absorption capacity is limited. Since diapers need to be worn directly on the body, when diapers absorb a large amount of water, the diapers will expand rapidly and the overall weight will increase. If the water absorption capacity of the diapers is designed to be high, the volume and weight of the diapers after absorbing water will be larger, which will cause greater discomfort. For the sake of comfort, the diapers that have not been completely absorbed will be directly replaced, which increases the cost of use. Second, under the condition of meeting comfort, the water absorption capacity is designed to be high. Diapers with insufficient water absorption capacity are difficult to meet the needs of adults who are inconvenient to move. The present invention provides a diaper layer stacking device for absorbent articles. A new diaper is produced by the device. The composite layer is transported by the first conveying shaft, and the absorbent layer is transported by the second conveying layer. The number of absorbent layers is two. The composite layer and the absorbent layer are stacked together, and then rolled together by the stacking roller to realize the composite of each layer. During the composite process, the width of one of the absorbent layers is narrow, and the absorbent layer will not contact the composite position. Therefore, the composite layer is produced. In the diapers disclosed herein, one of the absorption layers is a pull-out structure. When the diapers are used, the absorption layer in the pulled-out state absorbs water first, and after the absorption is completed, the other absorption layer starts to absorb water. In order to facilitate the rapid absorption of water by the other absorption layer and improve the wearing comfort of the diapers, the absorption layer in the pulled-out state can be pulled out manually. The present invention effectively realizes the composite structure of the multi-layer absorption layer inside the diaper, and one of the absorption layers can be directly pulled out after the absorption is completed through the pull-out design, which is convenient for the rapid absorption of water by the other absorption layer, while reducing the volume and weight of the diapers and improving the wearing comfort.

[0008] Preferably, third conveying shafts are rotatably connected to both sides of the absorption layer near the top of the machine body inside the machine body; guide sliding pads are connected to the surfaces of the third conveying shafts, and the guide sliding pads are compound-connected to the corresponding absorption layers through the third conveying shafts; during operation, by providing the third conveying shafts, through the rotation of the third conveying shafts, the guide sliding pads are directly pressed against the surface of the pullable absorption layer, and then the layers of the diaper are laminated. During the later use of the diaper, when this layer is fully water-absorbed, it will quickly expand, making it difficult to pull. The guide sliding pads compounded by this device can play a guiding and sliding role, facilitating the pulling of the absorption layer.

[0009] Preferably, fixing blocks are fixedly connected between the first conveying shaft and the second conveying shaft inside the machine body; the number of the fixing blocks is two, and they are respectively located on both sides of the absorption layer near the top of the machine body; rotating grooves are respectively formed on one side surfaces of the fixing blocks opposite to the corresponding absorption layers; rubber rollers are rotatably connected inside the rotating grooves, and the rubber rollers are connected to a glue storage pressure box; installation grooves are respectively formed at the bottoms of the rotating grooves; spray heads are fixedly connected inside the installation grooves; during operation, by providing the fixing blocks and the rubber rollers, through the rotation of the rubber rollers inside the corresponding fixing blocks, the rubber rollers can apply glue to the surface of the absorption layer. During the later lamination production process, the glue can basically bond the pulled absorption layer to the surrounding layers. Under the condition of just starting to use, the absorption layer cannot be directly pulled out, preventing children from directly pulling out the unwatered absorption layer when using it. At the same time, when the absorption layer absorbs a large amount of water, it will soak the glue, and then the glue loses its bonding effect. At this time, the absorption layer can be easily pulled.

[0010] Preferably, fixing grooves are respectively formed on the surfaces of the two fixing blocks near the corresponding rubber rollers; return boxes are fixedly connected inside the fixing grooves, and the openings of the return boxes correspond to the corresponding rubber rollers; scraping blades are fixedly connected to the mouths of the return boxes; during operation, by providing the return boxes, when the rubber rollers directly contact the water-absorbing layer to apply glue, a large amount of glue and fibers will remain on the surfaces of the rubber rollers, thereby affecting the subsequent sustainable glue application effect. The scraping blades at the opening positions of the return boxes can scrape off the excess glue from the rubber rollers and guide the glue into the return boxes, which are then refluxed and exported through the return boxes.

[0011] Preferably, rotating columns are rotatably connected to the mouths of the return boxes; rolling disks are fixedly connected to the ends of the rotating columns, and the rolling disks are in rolling connection with the corresponding rubber rollers; guide plates are fixedly connected to the surfaces of the rotating columns between the two rolling disks; during operation, by providing the rotating columns, the rolling disks and the guide plates, when the rubber rollers rotate, the rubber rollers will drive the rolling disks to rotate, the rolling disks will drive the rotating columns to rotate, and the rotating columns will drive the guide plates on their surfaces to rotate. Through the guide plates, the scraped-off glue can be promoted to be introduced into the return boxes, reducing the risk of glue blockage at the mouths of the return boxes.

[0012] Preferably, pressure-regulating rollers are rotatably connected near the position of the laminating rollers inside the machine body; sleeves are sleeved outside the pressure-regulating rollers; elastic pads are fixedly connected to the outer surfaces of the sleeves in a uniformly arranged manner; an elastic film is commonly connected to the outside of the elastic pads; the spaces between adjacent elastic pads are unidirectionally connected to the glue storage pressure box, and the spaces between the elastic pads are unidirectionally connected to the outside atmosphere; during operation, by setting the pressure-regulating rollers, sleeves are sleeved on the surfaces of the pressure-regulating rollers, and elastic pads are fixedly connected to the surfaces of the sleeves in a uniformly arranged manner. By leaving uniform spaces between the elastic pads, when the laminated sheets continue to be driven downward, the pressure-regulating rollers will be driven, and then the uniform spaces between the elastic pads on the surfaces of the pressure-regulating rollers will be successively squeezed, realizing continuous pressurization of the inside of the glue storage pressure box and ensuring the stability of the glue outlet pressure.

[0013] Preferably, springs are fixedly connected between the pressure-regulating rollers and the corresponding sleeves in a uniformly arranged manner; first pressing blocks are fixedly connected to the surfaces of the pressure-regulating rollers in a uniformly arranged manner; second pressing blocks are fixedly connected to the inner surfaces of the sleeves in a uniformly arranged manner; pressure sensors are fixedly connected to the surfaces of the first pressing blocks; during operation, by arranging springs in a uniformly arranged manner inside the pressure-regulating rollers and the sleeves, when the sleeve is squeezed, the sleeve will squeeze the corresponding spring on one side. If in the normal laminating state, at the edge position of the rolling composite, the draw-absorbing layer does not participate in the composite and the edge thickness is in the designed state. If the position of the draw-absorbing layer is abnormal and this absorbing layer participates in the composite, it will not be able to be normally drawn during later use. The extra draw layer participating in the composite will increase the edge thickness, which will further increase the extrusion on the sleeve, resulting in a greater eccentricity between the sleeve and the corresponding pressure-regulating roller. As a result, the first pressing block and the second pressing block will come into contact and squeeze the pressure sensor, outputting a pressure signal to remind of abnormal processing.

[0014] Preferably, cutting discs are rotatably connected near the side positions of the absorbing layer at the top inside the machine body; cutting knives are fixedly connected to the end faces of the cutting discs on the side relative to the absorbing layer in a uniformly arranged manner; during operation, by setting the cutting discs, when the cutting discs rotate, the cutting discs will drive the cutting knives fixedly connected to their surfaces to rotate, and the cutting knives can cut the excess edge materials of the draw-absorbing layer in a drawable state, preventing the excess edge materials of the absorbing layer from participating in the composite and affecting the normal drawing of the absorbing layer during later use.

[0015] Preferably, suction holes are provided at the axis positions of the cutting discs corresponding to the cutting discs; air guide holes are provided at the positions between the corresponding cutting knives on the surfaces of the cutting discs; during operation, by providing suction holes at the axis positions of the cutting discs, through the negative pressure inside the suction holes, the excess edge materials cut off can be quickly sucked out, preventing the edge materials from remaining inside the finished disposable diaper. During the drawing process, the absorbing layer will bring out excess shredded edge materials, affecting the use experience.

[0016] Preferably, the mouths of the air guide holes are rotatably connected with air jet heads; on one side surface of each air jet head relative to the air guide hole, a first spray hole is provided at a position corresponding to the axis of the air guide hole; on the side surface of the air jet head facing away from the air guide hole, a second spray hole is provided, and the second spray hole is communicated with the corresponding first spray hole; the second spray holes are all designed with an inclined structure; during operation, by arranging the air jet heads at the mouths of the air guide holes, since the second spray holes with an inclined state are provided on the surface of the air jet heads, the gas passing through the air guide holes will first be introduced into the first spray holes, and then be introduced into the second spray holes through the first spray holes, and the gas is obliquely discharged through the second spray holes. Under the action of the reaction force of the gas, the air jet heads rotate continuously, promoting the blowing of the cut-off edge materials, reducing the blowing dead angles, and promoting the complete discharge of the corner waste materials.

[0017] The beneficial effects of the present invention are as follows:

[0018] 1. By providing the machine body and the laminating roller, the laminating roller is rotatably connected inside the machine body, and a single lamination of multiple absorption layers is carried out, effectively realizing the composite structure of multiple water absorption layers inside the diaper. Moreover, one of the absorption layers is designed with a draw-out structure. After absorbing water, it can be directly drawn out, facilitating the rapid water absorption of another absorption layer, while reducing the volume and weight of the diaper and improving the wearing comfort.

[0019] 2. By providing the fixing block, the rubber roller and the nozzle, the rubber roller rotates inside the corresponding fixing block, and the rubber roller can apply glue to the surface of the absorption layer. During the subsequent lamination production process, the glue can basically bond the draw-out absorption layer and the surrounding layers. Under the condition of just starting to use, the absorption layer cannot be directly drawn out, preventing children from directly pulling out the unabsorbed absorption layer when using. At the same time, when the absorption layer absorbs a large amount of water, it will soak the glue, and then the glue loses its bonding effect, and at this time, the absorption layer can be easily drawn out.

Detailed implementation manners

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] Embodiment 1

[0032] Please refer to Figure 1-7As shown, a device for laminating absorbent articles for diapers comprises a body 1 and a laminating roller 2, wherein the body 1 is internally rotatably connected with a first conveying shaft 3; the number of the first conveying shafts 3 is two and they are symmetrically arranged; the surfaces of the two first conveying shafts 3 are both connected with a composite layer 4; the body 1 is internally rotatably connected with a second conveying shaft 5 between the two first conveying shafts 3; the number of the second conveying shafts 5 is two; the surfaces of the two conveying shafts are both connected with an absorbent layer 6; the body 1 is internally rotatably connected with a laminating roller 2; the number of the laminating rollers 2 is two; when working, in the prior art, Diapers are formed by overlapping different functional layers to form an integrated structure, but the integrated structure has some problems. First, the water absorption capacity is limited. Since diapers need to be worn directly on the body, when diapers absorb a large amount of water, the diapers will expand rapidly and the overall weight will increase. If the water absorption capacity of the diapers is designed to be high, the diapers after absorbing water will be larger in size and heavier in weight, which will cause greater discomfort. For the sake of comfort, diapers that have not been fully absorbed will be directly replaced, which increases the cost of use. Second, under the condition of meeting comfort, diapers with insufficient water absorption capacity are designed, which is not suitable for people who are not comfortable. When used by adults who are active, diapers with limited water absorption capacity cannot meet the needs of adults. Through the absorbent article layer stacking device for diapers of the present invention, a new diaper is produced by the device. The composite layer 4 is transported by the first conveying shaft 3, and the absorbent layer 6 is transported by the second conveying layer. The number of absorbent layers 6 is two. The composite layer 4 and the absorbent layer 6 are stacked together, and then rolled together by the stacking roller 2 to realize the composite of each layer. During the composite process, the width of one of the absorbent layers 6 is narrow, and the absorbent layer 6 will not contact the composite position. Therefore, the produced diaper One of the absorption layers 6 is a pull-out structure. When the diaper is used, the absorption layer 6 in the pulled-out state will absorb water first. After the absorption is completed, the other absorption layer 6 starts to absorb water. In order to facilitate the rapid absorption of water by the other absorption layer 6 and improve the wearing comfort of the diaper, the absorption layer 6 in the pulled-out state can be pulled out manually. The present invention effectively realizes the composite structure of multiple absorbent layers inside the diaper, and one of the absorption layers 6 can be directly pulled out after the absorption is completed through the pull-out design, which is convenient for the rapid absorption of water by the other absorption layer, while reducing the volume and weight of the diaper and improving the wearing comfort.

[0033] Inside the body 1, third conveying shafts 7 are rotatably connected to both sides of the absorption layer 6 near the top of the body 1; guide sliding pads 8 are connected to the surfaces of the third conveying shafts 7, and the guide sliding pads 8 are compound-connected to the corresponding absorption layer 6 through the third conveying shafts 7; during operation, by providing the third conveying shafts 7, through the rotation of the third conveying shafts 7, the guide sliding pads 8 are directly pressed against the surface of the pullable absorption layer 6, and then each layer of the diaper is laminated. During the later use of the diaper, after this layer is fully wetted, it will quickly expand, making it difficult to pull. The guide sliding pads 8 compounded by this device can play a guiding and sliding role, facilitating the pulling of the absorption layer 6.

[0034] Inside the body 1, fixing blocks 9 are fixedly connected between the first conveying shaft 3 and the second conveying shaft 5; the number of the fixing blocks 9 is two, and they are respectively located on both sides of the absorption layer 6 near the top of the body 1; rotating grooves are provided on one side surface of each fixing block 9 relative to the corresponding absorption layer 6; glue rollers 10 are rotatably connected inside the rotating grooves, and the glue rollers 10 are connected to a glue storage pressure tank; installation grooves are provided at the bottoms of the rotating grooves; spray heads 11 are fixedly connected inside the installation grooves; during operation, by providing the fixing blocks 9 and the glue rollers 10, through the rotation of the glue rollers 10 inside the corresponding fixing blocks 9, the glue rollers 10 can apply glue to the surface of the absorption layer 6. During the later lamination production process, the glue can basically bond the pulled absorption layer 6 to the surrounding layers. Under the initial use conditions, the absorption layer 6 cannot be directly pulled out, preventing children from directly pulling out the non-wetted absorption layer 6 when using it. At the same time, when the absorption layer 6 absorbs a large amount of water, it will soak the glue, and then the glue loses its bonding effect, and at this time, the absorption layer 6 can be easily pulled.

[0035] Fixing grooves are provided on the surfaces of the two fixing blocks 9 near the corresponding glue rollers 10; return boxes 12 are fixedly connected inside the fixing grooves, and the openings of the return boxes 12 correspond to the corresponding glue rollers 10; scraping blades 13 are fixedly connected to the mouths of the return boxes 12; during operation, by providing the return boxes 12, when the glue rollers 10 directly contact the water absorption layer to apply glue, a large amount of glue and fibers will remain on the surfaces of the glue rollers 10, thereby affecting the subsequent continuous glue application effect. The excess glue can be scraped off the glue rollers 10 by the scraping blades 13 at the opening positions of the return boxes 12, and the glue will be introduced into the return boxes 12 and flow out through the return boxes 12.

[0036] A rotating column 14 is rotatably connected to the mouth position of the reflux box 12; end portions of the rotating column 14 are fixedly connected with rolling discs 15, and the rolling discs 15 are in rolling connection with corresponding rubber rollers 10; guide plates 16 are fixedly connected to the surface of the rotating column 14 between the two rolling discs 15; during operation, by providing the rotating column 14, the rolling discs 15 and the guide plates 16, when the rubber roller 10 rotates, the rubber roller 10 drives the rolling disc 15 to rotate, the rolling disc 15 drives the rotating column 14 to rotate, and the rotating column 14 drives the guide plates 16 on its surface to rotate. The guide plates 16 can promote the glue scraped off to be introduced into the reflux box 12, reducing the risk of glue clogging at the mouth of the reflux box 12.

[0037] Pressure regulating rollers 17 are rotatably connected to the inside of the machine body 1 near the laminating roller 2; sleeves 18 are sleeved outside the pressure regulating rollers 17; uniformly arranged elastic pads 19 are fixedly connected to the outer surfaces of the sleeves 18; an elastic film 20 is commonly connected to the outside of the elastic pads 19; the spaces between adjacent elastic pads 19 are in one-way connection with the glue storage pressure box, and the spaces between the elastic pads 19 are in one-way connection with the outside atmosphere; during operation, by providing the pressure regulating rollers 17, sleeves 18 are sleeved on the surfaces of the pressure regulating rollers 17, and uniformly arranged elastic pads 19 are fixedly connected to the surfaces of the sleeves 18. Uniform spaces are left between the elastic pads 19. When the laminated sheets continue to be transmitted downward, the pressure regulating rollers 17 are driven, and then the uniform spaces between the elastic pads 19 on the surfaces of the pressure regulating rollers 17 are sequentially squeezed, realizing continuous pressurization of the inside of the glue storage pressure box and ensuring the stability of the glue export pressure.

[0038] Uniformly arranged springs 21 are fixedly connected between the pressure regulating rollers 17 and the corresponding sleeves 18; uniformly arranged first pressing blocks 22 are fixedly connected to the surfaces of the pressure regulating rollers 17; uniformly arranged second pressing blocks 23 are fixedly connected to the inner surfaces of the sleeves 18; pressure sensors 24 are fixedly connected to the surfaces of the first pressing blocks 22; during operation, by providing uniformly arranged springs 21 inside the pressure regulating rollers 17 and the sleeves 18, when the sleeve 18 is squeezed, the sleeve 18 squeezes the corresponding spring 21 on one side. If in the normal laminating state, at the edge position of the rolling composite, the drawable absorbent layer 6 does not participate in the composite and the edge thickness is in the designed state. If the position of the drawable absorbent layer 6 is abnormal and this absorbent layer 6 participates in the composite, it will not be able to be drawn normally during later use. The redundant drawable layer participating in the composite will increase the edge thickness, further increasing the squeeze on the sleeve 18, and the eccentricity between the sleeve 18 and the corresponding pressure regulating roller 17 will be greater, further causing the first pressing block 22 and the second pressing block 23 to contact and squeeze the pressure sensor 24, outputting a pressure signal to remind of abnormal processing.

[0039] Embodiment Two

[0040] Please refer to Figure 8As shown in the figure, there is a laminating device for absorbent article sheets used in disposable diapers. Inside the machine body 1, cutting discs 25 are rotatably connected near the side positions of the absorbent layer 6 at the top. On one end face of each cutting disc 25 relative to the absorbent layer 6, evenly arranged cutting knives 26 are fixedly connected. During operation, by setting the cutting discs 25, when the cutting discs 25 rotate, the cutting discs 25 will drive the evenly arranged cutting knives 26 on their surfaces to rotate. The cutting knives 26 can cut the excess edge materials of the absorbent layer 6 in a pullable state, preventing the excess edge materials of the absorbent layer 6 from participating in the lamination and affecting the normal pulling of the absorbent layer 6 during later use.

[0041] On the surface of each cutting disc 25 at positions corresponding to the axis of the cutting disc 25, suction holes 27 are provided. On the surface of each cutting disc 25 at positions between the corresponding cutting knives 26, air guide holes 28 are provided. During operation, by providing the suction holes 27 at the axis positions of the cutting discs 25, due to the negative pressure inside the suction holes 27, the cut excess edge materials can be quickly sucked out, preventing the edge materials from remaining inside the finished disposable diaper. During the pulling process, the absorbent layer 6 may bring out excess shredded edge materials, affecting the use experience.

[0042] At the mouths of the air guide holes 28, air jet heads 29 are rotatably connected. On one side surface of each air jet head 29 relative to the air guide hole 28 at the position corresponding to the axis of the air guide hole 28, first spray holes 30 are provided. On the other side surface of the air jet head 29 away from the air guide hole 28, second spray holes 31 are provided, and the second spray holes 31 communicate with the corresponding first spray holes 30. The second spray holes 31 are all designed with an inclined structure. During operation, by providing the air jet heads 29 at the mouths of the air guide holes 28, since the second spray holes 31 on the surface of the air jet heads 29 are in an inclined state, the gas passing through the air guide holes 28 will first be introduced into the first spray holes 30, and then through the first spray holes 30 into the second spray holes 31. The gas is obliquely ejected through the second spray holes 31. Due to the reaction force of the gas, the air jet heads 29 continuously rotate, promoting the blowing of the cut edge materials, reducing the blowing dead corners, and promoting the complete export of the corner waste materials.

[0043] Working principle: A brand-new diaper is produced by this device. The composite layer 4 is conveyed through the first conveying shaft 3, and at the same time, the absorbent layer 6 is conveyed through the second conveying layer. The number of absorbent layers 6 is two. The composite layer 4 and the absorbent layer 6 are stacked together and then jointly rolled by the laminating roller 2 to achieve the lamination of each layer. During this lamination process, the width of one of the absorbent layers 6 is relatively narrow, and this absorbent layer 6 does not come into contact with the lamination position. Therefore, in the produced diaper, one of the absorbent layers 6 is a pull-out structure. When using the diaper, first, the absorbent layer 6 in the pull-out state will absorb water first. After completing the water absorption, the other absorbent layer 6 will start to absorb water. To facilitate the rapid water absorption of the other absorbent layer 6 and improve the wearing comfort of the diaper, the absorbent layer 6 in the pull-out state can be pulled out manually; by setting the third conveying shaft 7, through the rotation of the third conveying shaft 7, the guide sliding pad 8 is directly pressed on the surface of the pull-out absorbent layer 6, and then the layers of the diaper are laminated. During the later use of the diaper, after this layer is fully water-absorbed, it will expand rapidly, making it difficult to pull out. The guide sliding pad 8 laminated by this device can play a guiding and sliding role to facilitate the pulling of the absorbent layer 6; by setting the fixing block 9 and the rubber roller 10, through the rotation of the rubber roller 10 inside the corresponding fixing block 9, the rubber roller 10 can apply glue to the surface of the absorbent layer 6. During the later lamination production process, the glue can bond the pulled-out absorbent layer 6 to the surrounding layers. Under the initial use conditions, the absorbent layer 6 cannot be directly pulled out, preventing children from directly pulling out the unabsorbed absorbent layer 6 when using it. At the same time, when the absorbent layer 6 absorbs a large amount of water, it will soak the glue, and then the glue loses its bonding effect, and at this time, the absorbent layer 6 can be easily pulled out; by setting the return box 12, when the rubber roller 10 directly contacts the water-absorbing layer to apply glue, a large amount of glue and fibers will remain on the surface of the rubber roller 10, which will affect the subsequent continuous glue application effect. The excess glue can be scraped off the rubber roller 10 by the scraping blade 13 at the opening position of the return box 12, and the glue will be introduced into the return box 12 and exported through the return of the return box 12; by setting the rotating column 14, the rolling disc 15, and the guide plate 16, when the rubber roller 10 rotates, the rubber roller 10 will drive the rolling disc 15 to rotate, the rolling disc 15 will drive the rotating column 14 to rotate, and the rotating column 14 will drive the guide plate 16 on its surface to rotate. Through the guide plate 16, the scraped-off glue can be promoted to be introduced into the return box 12, reducing the risk of glue blockage at the mouth of the return box 12; by setting the pressure-regulating roller 17, a sleeve 18 is sleeved on the surface of the pressure-regulating roller 17, and evenly arranged elastic pads 19 are fixedly connected to the surface of the sleeve 18. There are uniform spaces between the elastic pads 19. When the laminated sheet continues to move downward, the pressure-regulating roller 17 will be driven, and then the uniform spaces between the elastic pads 19 on the surface of the pressure-regulating roller 17 will be sequentially squeezed, realizing continuous pressurization inside the glue storage pressure box to ensure the stability of the glue export pressure;By arranging springs 21 evenly inside the pressure-regulating roller 17 and the sleeve 18, when the sleeve 18 is squeezed, the sleeve 18 will squeeze the corresponding spring 21 on one side. In the normal lamination state, at the position of the rolled composite edge, the draw-absorbing layer 6 does not participate in the lamination, and the edge thickness is in the designed state. If the position of the draw-absorbing layer 6 is abnormal and this absorbing layer 6 participates in the lamination, it will not be able to be drawn normally during later use. The redundant draw layer participating in the lamination will increase the edge thickness, which will further increase the extrusion on the sleeve 18, and the eccentricity between the sleeve 18 and the corresponding pressure-regulating roller 17 will be greater. As a result, the first pressing block 22 and the second pressing block 23 will come into contact and squeeze the pressure sensor 24 to output a pressure signal, reminding of abnormal processing. By providing a cutting disc 25, when the cutting disc 25 rotates, the cutting disc 25 will drive the cutting knives 26 evenly arranged on its surface to rotate. The cutting knives 26 can cut the redundant edge materials of the draw-absorbing layer 6 in a drawable state, preventing the redundant edge materials of the absorbing layer 6 from participating in the lamination and affecting the normal drawing of the absorbing layer 6 during later use. By opening suction holes 27 at the axial position of the cutting disc 25, through the negative pressure inside the suction holes 27, the cut redundant edge materials can be quickly sucked out, preventing the edge materials from remaining inside the finished disposable diaper. During the drawing process, the absorbing layer 6 will bring out redundant shredded edge materials, affecting the use experience. By providing a jet head 29 at the mouth of the air guide hole 28, since the second jet holes 31 are provided on the surface of the jet head 29 in an inclined state, the gas passing through the air guide hole 28 will first be introduced into the first jet hole 30, and then through the first jet hole 30 into the second jet hole 31. The gas is obliquely discharged through the second jet hole 31. Under the action of the reaction force of the gas, the jet head 29 rotates continuously, promoting the blowing of the cut edge materials, reducing the blowing dead corners, and promoting the complete discharge of the corner waste materials.;
