Description

Technical Field

[0001] This invention belongs to the field of hygiene products technology, and in particular relates to a composite core manufacturing device and process. Background Technology

[0002] The absorbent core is the most important component of disposable absorbent products. Currently, absorbent cores on the market are mostly divided into two types: one is a cotton core, which consists of fluff pulp and SAP wrapped in lint-free paper or hydrophilic fabric; the other is a composite core, which generally consists of two outermost layers of non-woven fabric and an inner absorbent layer.

[0003] Consumers of absorbent products are currently demanding thinner versions. To meet these demands, manufacturers are reducing the thickness of absorbent products by creating composite cores. In existing technologies, composite cores are mostly constructed from an upper material, a middle absorbent layer, and a lower material. These materials are typically bonded together using adhesives. While this results in thinner absorbent cores, they have performance drawbacks. Specifically, the longitudinal penetration rate of liquid from the surface to the bottom layer and the lateral diffusion rate along the surface of the composite absorbent core are slow, leading to excessive localized liquid accumulation and potential side leakage or flooding.

[0004] Existing technologies use composite cores with flow channels to address the aforementioned slow diffusion rate problem, but these flow channels are all continuous straight channels with a single shape, making it impossible to create composite cores with discontinuous or irregular shapes. Summary of the Invention

[0005] To address the shortcomings of existing technologies where the guide channel has a single shape, this invention provides a composite core manufacturing apparatus and process.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a composite core manufacturing apparatus, comprising...

[0007] An unwinding mechanism is used to unwind the upper layer material, the middle layer material, and the lower layer material.

[0009] A feeding mechanism is used to apply liquid-absorbing filler between the upper and lower layers of material;

[0010] The packing suction and removal mechanism includes a first negative pressure chamber and a suction and removal mold. The suction and removal mold has a model area, which includes a suction and removal area and a retention area. The suction and removal area passes through the suction and removal mold and is connected to the first negative pressure chamber. The retention area is isolated from the first negative pressure chamber and is used to selectively suction and remove the applied liquid-absorbing packing.

[0011] Composite mechanisms are used to combine upper, middle, and lower layer materials.

[0012] In some embodiments, the unwinding mechanism includes a first unwinding mechanism for unwinding the upper layer material, a second unwinding mechanism for unwinding the middle layer material, and a third unwinding mechanism for unwinding the lower layer material.

[0013] In some embodiments, a heating mechanism is provided on one side of the second unwinding mechanism.

[0015] In some embodiments, the system further includes a first bonding position and a second bonding position, wherein the intermediate layer material and the lower layer material are bonded together at the first bonding position to form a lower composite layer, and the upper layer material and the lower composite layer are bonded together at the second bonding position to form a composite layer.

[0016] In some embodiments, the feeding mechanism is provided in two sets, which are disposed between the first bonding position and the second bonding position, for applying liquid-absorbing filler to the intermediate layer material of the lower composite layer, and the filler suction and removal mechanism is located between the feeding mechanism and the second bonding position.

[0017] In some embodiments, the feeding mechanism is configured as two groups, including a first feeding mechanism disposed between the third unwinding mechanism and the first bonding position and a second feeding mechanism disposed between the first bonding position and the second bonding position; the filler suction and removal mechanism is configured as two groups, including a first filler suction and removal mechanism located between the first feeding mechanism and the first bonding position and a second filler suction and removal mechanism located between the second feeding mechanism and the second bonding position.

[0018] In some embodiments, a negative pressure mechanism is further provided opposite to the filler adsorption and desorption mechanism. The negative pressure mechanism includes a second negative pressure chamber and an adsorption mold. The adsorption mold includes an adsorption zone and a non-adsorption zone. The adsorption zone extends through the adsorption mold and communicates with the second negative pressure chamber. The adsorption zone corresponds to the retention zone, and the non-adsorption zone corresponds to the adsorption and desorption zone.

[0019] In some embodiments, the model area further includes a partition area, which extends through the guide channel and communicates with the first negative pressure chamber. The partition area extends along the width direction of the composite core, and the length of the partition area is not less than the width of the composite core. The partition area is located at both ends of the suction and desorption area.

[0020] In some embodiments, the surface of the suction mold is covered with an isolation mesh, the mesh size of which is smaller than the size of the liquid suction packing, and a waste collection port is also provided on one side of the packing suction mechanism.

[0021] In some embodiments, the adhesive application mechanism includes a first adhesive application mechanism for applying adhesive to the bottom surface of the upper layer material, a second adhesive application mechanism for applying adhesive to the lower surface of the intermediate layer material, and a third adhesive application mechanism for applying adhesive to the upper surface of the lower layer material.

Moreover, the shape of the adsorption and desorption area can be set as needed, and a composite core with any shape of guide groove can be formed. Attached Figure Description

[0032] The present application will be further described below with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of the present application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without making creative changes are within the protection scope of the present application.

[0033] like Figure 1 , 3 As shown in Figure 5, the technical solution adopted by the present invention is: a composite core 1 fabrication apparatus, comprising...

[0034] An unwinding mechanism is used to unwind the upper layer material 10, the middle layer material 20, and the lower layer material 30;

[0035] An adhesive application mechanism is used to apply adhesive to the surface of the upper layer material 10, the middle layer material 20, or the lower layer material 30;

[0036] The feeding mechanism 300 is used to apply liquid-absorbing filler between the upper material 10 and the lower material 30;

[0037] The packing suction and removal mechanism 400 includes a first negative pressure chamber 401 and a suction and removal mold 402. The suction and removal mold 402 has a model area, which includes a suction and removal area 403 and a retention area 406. The suction and removal area 403 passes through the suction and removal mold 402 and is connected to the first negative pressure chamber 401. The retention area 406 is isolated from the first negative pressure chamber 401 and is used for selectively suctioning and removing the applied liquid-absorbing packing.

[0038] Composite mechanism 500 is used to composite upper material 10, middle material 20 and lower material 30.

[0039] By setting a suction stripping zone 403 and a retention zone 406 on the suction stripping mold 402, since the suction stripping zone 403 is connected to the first negative pressure chamber 401, the suction force generated by the negative pressure of the negative pressure chamber can remove the liquid-absorbing packing corresponding to the suction stripping zone 403. Meanwhile, the retention zone 406 is isolated from the first negative pressure chamber 401, and the liquid-absorbing packing corresponding to the retention zone 406 is retained, thus achieving selective suction stripping of the liquid-absorbing packing. The shape of the suction stripping zone 403 can be set according to actual needs. For example, the suction stripping zone 403 can be composed of multiple parallel through grooves, each through groove can be continuous or discontinuous, thus forming a continuous guide channel 1-1 (e.g., Figure 6 (as shown) or discontinuous guide channels 1-1 (such as Figure 7 (As shown), the through groove forming the suction / desorption zone 403 can also be set to any irregular shape, such as... Figure 2 As shown, a V-shaped structure is formed at both ends of one of the through grooves. On the composite core 1 corresponding to the suction and desorption zone 403, since the liquid-absorbing packing is removed, a guide groove 1-1 is formed. The shape of the guide groove 1-1 is the same as the shape of the suction and desorption zone 403, which solves the problem that the guide groove 1-1 of the composite core 1 in the prior art has a single shape and cannot be made into a composite core 1 with a discontinuous or irregular shape guide groove 1-1.

[0040] like Figure 2 As shown, the filler suction and removal mechanism 400 can be in the form of an adsorption roller. The adsorption roller is rotated and a hollow first negative pressure chamber 401 is formed at its center. A suction and removal mold is formed on its surface, and multiple model areas can be formed on the surface. During the rotation of the adsorption roller, the multiple model areas alternately act on the composite core 1.

[0041] like Figure 1 , 3 As shown in ~5, specifically, in order to facilitate the unwinding of the upper layer material 10, the middle layer material 20 and the lower layer material 30, in some embodiments, the unwinding mechanism includes a first unwinding mechanism 101 for unwinding the upper layer material 10, a second unwinding mechanism 102 for unwinding the middle layer material 20 and a third unwinding mechanism 103 for unwinding the lower layer material 30.

[0042] like Figure 1 , 3 As shown in Figure 5, the upper layer material 10 and the lower layer material 30 are typically non-woven fabrics, while the middle layer material 20 is made of a fluffy non-woven fabric. In some embodiments, a heating mechanism 600 is provided on one side of the second unwinding mechanism 102. After the middle layer material 20 is unwound, passing it through the heating mechanism 600 further enhances the fluffiness of the fluffy non-woven fabric, facilitating the entry of the absorbent filler into its gaps. The heating mechanism 600 can be an oven.

[0043] like Figure 1 , 3As shown in Figure 5, the liquid-absorbing filler added by the feeding mechanism 300 is usually in granular form. When applied to the surface of the intermediate layer material 20 or the lower layer material 30, it is prone to splashing or scattering. In some embodiments, a vacuum box 700 is provided below the feeding mechanism 300. The vacuum box 700 generates negative pressure suction on the lower surface of the lower layer material 30, thereby adsorbing the applied liquid-absorbing filler and preventing splashing or scattering.

[0044] like Figure 1 , 3 As shown in Figure 5, in some embodiments, a first bonding position 801 and a second bonding position 802 are also included. The intermediate layer material 20 and the lower layer material 30 are bonded together at the first bonding position 801 to form a lower composite layer, and the upper layer material 10 and the lower composite layer are bonded together at the second bonding position 802 to form a composite layer. Specifically, a first guide roller is provided at the first bonding position 801, and a second guide roller is provided at the second bonding position 802. At the first guide roller, the intermediate layer material 20 and the lower layer material 30 converge and are then bonded together to form the lower composite layer. At the second guide roller, the lower composite layer and the upper layer material 10 converge and are then bonded together to form the composite layer.

[0045] like Figure 1 and 4 As shown, to facilitate the addition of different absorbent fillers to the composite core 1, in some embodiments, the feeding mechanism 300 is configured as two sets, with the two sets of feeding mechanisms 300 positioned between the first bonding position 801 and the second bonding position 802, for applying absorbent fillers to the intermediate layer material 20 of the lower composite layer. The filler suction and removal mechanism 400 is located between the feeding mechanism 300 and the second bonding position 802. The intermediate layer material 20 and the lower layer material 30 are bonded together between the first bonding position 801 and the second bonding position 802 to form the lower composite layer. The two sets of feeding mechanisms 300 apply absorbent fillers to the upper surface of the lower composite layer. Since the intermediate layer material 20 is a loose non-woven fabric, the absorbent filler can fall through the gaps in the loose non-woven fabric and penetrate into the interior of the loose non-woven fabric, especially under the negative pressure suction of the vacuum box 700.

[0046] like Figure 3 and 5As shown, in order to adjust the distribution of the liquid-absorbing filler in the lower composite layer, in some embodiments, the feeding mechanism 300 is configured as two sets, including a first feeding mechanism 301 disposed between the third unwinding mechanism 103 and the first bonding position 801 and a second feeding mechanism 302 disposed between the first bonding position 801 and the second bonding position 802; the filler suction and removal mechanism 400 is configured as two sets, including a first filler suction and removal mechanism 400 located between the first feeding mechanism 301 and the first bonding position 801 and a second filler suction and removal mechanism 400 located between the second feeding mechanism 302 and the second bonding position 802. The first feeding mechanism 301 directly applies liquid-absorbing filler to the upper surface of the lower layer material 30, and the second feeding mechanism 302 directly applies liquid-absorbing filler to the upper surface of the lower composite layer. The liquid-absorbing filler can penetrate into the interior of the fluffy non-woven fabric of the middle layer material 20 under the action of gravity and vacuum box 700, making the distribution of liquid-absorbing filler in the composite core 1 more uniform, avoiding the situation where there is no liquid-absorbing filler on the upper surface of the lower layer material 30, and making the liquid absorption effect of the composite core 1 more ideal.

[0047] like Figure 1 , 3As shown in Figure 5, since the intermediate layer material 20 is a loose non-woven fabric, when the suction and detachment zone 403 detaches the liquid-absorbing filler corresponding to the area of ​​the composite core 1, it can not only detach the liquid-absorbing filler in the area corresponding to the suction and detachment zone 403, but also the liquid-absorbing filler around this area will be detached due to the suction force of the suction and detachment zone 403. In order to improve the suction and detachment effect of the liquid-absorbing filler, in some embodiments, a negative pressure mechanism 900 is also included, which is arranged opposite to the filler suction and detachment mechanism 400. The negative pressure mechanism 900 includes a second negative pressure chamber 901 and an adsorption mold. The adsorption mold includes an adsorption area and a non-adsorption area. The adsorption area penetrates the adsorption mold and is connected to the second negative pressure chamber 901. The adsorption area corresponds to the retention area 406, and the non-adsorption area corresponds to the suction and detachment zone 403. In this embodiment, the negative pressure mechanism 900, which is arranged opposite to the filler suction and detachment mechanism 403, can achieve precise suction and detachment of the area of ​​the composite core 1 corresponding to the suction and detachment zone 403, avoiding the influence on the surrounding area. Specifically, a non-adsorption zone is set on the negative pressure mechanism 900 corresponding to the adsorption zone 403 of the packing adsorption mechanism 400, and an adsorption zone is set on the negative pressure mechanism 900 corresponding to the retention zone 406 of the packing adsorption mechanism 400. When the adsorption zone 403 of the packing adsorption mechanism 400 adsorbs and removes the liquid from the area corresponding to the composite core 1, and the non-adsorption zone of the negative pressure mechanism 900 corresponds to that area, only the adsorption zone 403 of the packing adsorption mechanism 400 generates an adsorption force on that area, thereby removing the adsorbed liquid. The filler is adsorbed into the adsorption / desorption zone 403; while in the composite core 1 region corresponding to the retention zone 406 of the filler adsorption / desorption mechanism 400, the adsorption zone of the negative pressure mechanism 900 provides negative pressure suction. The negative pressure suction in this region is opposite to the negative pressure suction in the adsorption / desorption zone 403, causing the liquid-absorbing filler in this region of the composite core 1 to be drawn away by the adsorption / desorption zone 403, effectively avoiding the influence of the adsorption / desorption zone 403 on this region, and ensuring that the shape of the guide channel 1-1 formed by the composite core 1 is basically consistent with the shape of the adsorption / desorption zone 403. Specifically, the negative pressure mechanism 900 can also be in the form of an adsorption roller, with a hollow second negative pressure chamber 901 formed in its center, and the adsorption zone and non-adsorption zone formed on its surface. During rotation, the adsorption zone corresponds to the retention zone 406, and the non-adsorption zone corresponds to the adsorption zone.

[0048] like Figure 2As shown, when the composite core 1 is divided into individual core units, the absorbent packing is exposed at the cut, which can easily cause leakage. In some embodiments, the model area also includes a partition area 404, which extends through the guide channel 1-1 and communicates with the first negative pressure chamber 401. The partition area 404 extends along the width direction of the composite core 1, and its length is not less than the width of the composite core 1. The partition area 404 is located at both ends of the suction and removal area 403. The absorbent packing at the corresponding position of the composite core 1 is removed using the partition area 404, meaning that there is no absorbent packing in this area, forming the partition channel 1-2. This area can be used to divide the composite core 1 into individual core units. This area only contains adhesive and will not expose the absorbent packing, thus preventing packing leakage. Figure 6 and 7 As shown.

[0049] The aforementioned first negative pressure chamber 401 can be directly connected to the recovery device, thereby collecting the liquid-absorbing packing removed by the packing suction and removal mechanism 400.

[0050] like Figure 4 and 5 As shown, as an improvement to the aforementioned filler suction and removal mechanism 400, in some embodiments, the surface of the suction and removal mold 402 is covered with an isolation mesh. The mesh size of the isolation mesh is smaller than the size of the liquid-absorbing filler. A waste collection port 405 is also provided on one side of the filler suction and removal mechanism 400. The isolation mesh prevents the liquid-absorbing filler from being adsorbed into the first negative pressure chamber 401, but instead allows it to be adsorbed onto the isolation mesh, and then the liquid-absorbing filler on the isolation mesh is sucked away and collected through the waste collection port 405. Specifically, the isolation mesh can be covered on the surface of the suction roller.

[0051] like Figure 1 As shown in Figures 3-5, in some embodiments, the adhesive application mechanism includes a first adhesive application mechanism 201 for applying adhesive to the bottom surface of the upper layer material 10, a second adhesive application mechanism 202 for applying adhesive to the lower surface of the intermediate layer material 20, and a third adhesive application mechanism 203 for applying adhesive to the upper surface of the lower layer material 30. Applying adhesive to the upper layer material 10, the intermediate layer material 20, and the lower layer material 30 not only effectively bonds the three layers together but also effectively adheres the applied absorbent filler.

[0052] like Figure 1As shown in Figures 3-5, specifically, the composite mechanism 500 can be a hot-press composite mechanism 500, thereby thermally bonding the composite core 1. A folding mechanism 501 is also provided between the composite mechanism 500 and the second bonding position 802, used to fold the lower material 30 and the upper material 10. Specifically, the upper material 10 is folded upwards, and the lower material 30 is also folded upwards, forming a folded edge on the side of the composite core 1, such as... Figure 6 and 7 As shown, this is to prevent leakage of the liquid-absorbing packing.

[0053] The present invention also provides a manufacturing process for a composite core 1, comprising unwinding an upper layer material 10, an intermediate layer material 20 and a lower layer material 30, applying an adhesive to the surface of the upper layer material 10, the intermediate layer material 20 or the lower layer material 30, applying a liquid-absorbing filler between the upper layer material 10 and the lower layer material 30, selectively removing the applied liquid-absorbing filler using a filler removal mechanism 400, and then combining the upper layer material 10, the intermediate layer material 20 and the lower layer material 30.

[0054] like Figure 6 and 7 As shown, the prepared composite core 1, due to its guiding groove 1-1, possesses diffusion and permeation properties, significantly increasing the liquid absorption rate. After liquid absorption, the liquid-absorbing filler expands. Because the liquid-absorbing filler in the guiding groove 1-1 region of the composite core 1 is absorbed, the cross-sectional area of ​​the guiding groove 1-1 region is smaller than other regions, providing a liquid-guiding effect and better flow guidance. Simultaneously, the guiding groove is bonded with adhesive and does not expand, thus fixing the liquid-absorbing filler and ensuring that the composite core 1 does not clump or break after multiple washes. Furthermore, by setting the partition area 404, the applied liquid-absorbing filler will not leak during the cutting of the composite core 1, increasing the life of the core cutter while saving filler material and reducing costs.

[0055] While the disclosure is as stated above, its scope of protection is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of this disclosure, and all such changes and modifications will fall within the scope of protection of this application.
