Description

Technical Field

[0001] The invention belongs to the technical field of sanitary products, and in particular relates to a composite core manufacturing device and process. Background Art

[0002] The absorbent core is the most important component of disposable absorbent products. Currently, there are two types of absorbent cores on the market. One is the cotton core, which is composed of fluff pulp and SAP wrapped by dust-free paper or hydrophilic cloth. The other is the composite core, which is generally composed of the outer two layers of non-woven fabric and the middle water-absorbing layer.

[0003] Consumers of absorbent products are currently demanding thinner absorbent products. In order to meet these demands, manufacturers are reducing the thickness of absorbent products by making composite cores. In the prior art, composite cores are mostly made of upper materials, middle absorbent layers, and lower materials. The upper materials, middle absorbent layers, and lower materials of the absorbent core are generally bonded together with adhesives. Although the resulting absorbent cores are thinner, their performance is defective. The disadvantage is that the longitudinal penetration rate of liquid from the surface layer to the bottom layer and the lateral diffusion rate along the surface of the composite absorbent core are slow, resulting in excessive accumulation of liquid in some areas, causing side leakage or flooding.

[0004] The prior art manufactures a composite core with a guide groove to solve the above-mentioned problem of slow diffusion speed, but the guide groove is a continuous straight groove with a single shape, and there is no way to manufacture a composite core with a discontinuous or irregular shape. Summary of the invention

[0005] In order to solve the defect of the single shape of the guide groove in the prior art, the present invention provides a composite core manufacturing device and process.

[0032] The present application will be further described below in conjunction with specific implementation methods. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative changes belong to 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 manufacturing device, including

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

[0035] A glue applying mechanism, used for applying adhesive to the surface of the upper layer material 10, the middle layer material 20 or the lower layer material 30;

[0036] A feeding mechanism 300 for applying a liquid-absorbing filler between the upper material 10 and the lower material 30;

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

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

[0039] By setting the suction-release zone 403 and the retention zone 406 on the suction-release mold 402, since the suction-release 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 be used to remove the absorbent filler corresponding to the suction-release zone 403, while the retention zone 406 is isolated from the first negative pressure chamber 401, and the absorbent filler corresponding to the retention zone 406 is retained, thereby achieving selective absorption and removal of the absorbent filler. The shape of the suction-release zone 403 can be set according to actual needs, such as the suction-release zone 403 is composed of a plurality of through grooves arranged in parallel, each of which can be continuous or discontinuous, thereby forming a continuous guide groove 1-1 (such as Figure 6 As shown) or discontinuous guide groove 1-1 (as shown Figure 7 As shown), the through grooves forming the adsorption / desorption zone 403 may 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. Since the liquid absorbing filler is removed on the composite core 1 corresponding to the absorption and desorption zone 403, a guide groove 1-1 is formed, and the shape of the guide groove 1-1 is the same as the shape of the absorption 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 of the 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, which is rotatably arranged to form a hollow first negative pressure chamber 401 at its center, and a suction and removal film is formed on its surface. Multiple model areas can be formed on the surface, and during the rotation of the adsorption roller, the multiple model areas act alternately on the composite core 1.

[0041] like Figure 1 , 3 As shown in Figures 5 to 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 Figures 5 to 6, the upper layer material 10 and the lower layer material 30 are usually non-woven fabric materials, and the middle layer material 20 is selected from fluffy non-woven fabric materials. 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, the middle layer material 20 is passed through the heating mechanism 600, which can make the fluffy non-woven fabric of the middle layer material 20 more fluffy, making it easier for the liquid-absorbing filler to enter the gaps therein. The heating mechanism 600 can be an oven.

[0043] like Figure 1 , 3As shown in Figures 5 to 6, the liquid-absorbing filler added by the feeding mechanism 300 is usually in the form of particles, which are prone to splashing or scattering when applied to the surface of the middle layer material 20 or the surface of the lower layer material 30. In some embodiments, a vacuum box 700 is provided below the feeding mechanism 300. The vacuum box 700 is provided to generate negative pressure suction on the lower surface of the lower layer material 30, thereby adsorbing the applied liquid-absorbing filler to avoid splashing or scattering.

[0044] like Figure 1 , 3 As shown in Figures 5 to 6, in some embodiments, a first laminating position 801 and a second laminating position 802 are further included. The intermediate material and the lower layer material 30 are laminated at the first laminating position 801 to form a lower composite layer, and the upper layer material 10 and the lower composite layer are laminated at the second laminating position 802 to form a composite layer. Specifically, a first guide roller is provided at the first laminating position 801, and a second guide roller is provided at the second laminating position 802. The intermediate layer material 20 and the lower layer material 30 meet at the first guide roller, and then are pasted and composited together to form a lower composite layer. The lower composite layer meets the upper layer material 10 at the second guide roller, and then are pasted and composited together to form a composite layer.

[0045] like Figure 1 and 4 As shown, in order to facilitate adding different liquid-absorbing fillers to the composite core 1, in some embodiments, the feeding mechanism 300 is set as two groups, and the two groups of the feeding mechanism 300 are arranged between the first laminating position 801 and the second laminating position 802, and are used to apply the liquid-absorbing filler to the middle layer material 20 of the lower composite layer, and the filler suction and removal mechanism 400 is located between the feeding mechanism 300 and the second laminating position 802. Between the first laminating position 801 and the second laminating position 802 is the middle layer material 20 and the lower layer material 30 pasted and composited to form the lower composite layer, and the two groups of feeding mechanisms 300 apply the liquid-absorbing filler to the upper surface of the lower composite layer. Since the middle layer material 20 is a fluffy non-woven fabric, the liquid-absorbing filler can fall through the gaps in the fluffy non-woven fabric and penetrate into the inside of the fluffy non-woven fabric, especially under the action of 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 set into two groups, including a first feeding mechanism 301 arranged between the third unwinding mechanism 103 and the first bonding position 801 and a second feeding mechanism 302 arranged between the first bonding position 801 and the second bonding position 802; the filler suction and removal mechanism 400 is set into two groups, 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 the absorbent filler to the upper surface of the lower material 30, and the second feeding mechanism 302 directly applies the absorbent filler to the upper surface of the lower composite layer. The absorbent filler can penetrate into the interior of the fluffy non-woven fabric of the middle layer material 20 under the action of gravity and the vacuum box 700, so that the distribution of the absorbent filler in the composite core 1 is more uniform, avoiding the situation where there is no absorbent filler on the upper surface of the lower material 30, and making the absorbent effect of the composite core 1 more ideal.

[0047] like Figure 1 , 3As shown in Figures 5 to 6, since the middle layer material 20 is a fluffy non-woven fabric material, when the suction and desorption zone 403 absorbs and desorbs the liquid-absorbing filler in the corresponding area of ​​the composite core 1, not only the liquid-absorbing filler in the area corresponding to the suction and desorption zone 403 can be absorbed and desorbed, but also the liquid-absorbing filler around the area will be absorbed and desorbed under the influence of the suction force of the suction and desorption zone 403. In order to improve the absorption and desorption effect of the liquid-absorbing filler, in some embodiments, a negative pressure mechanism 900 arranged opposite to the filler absorption and desorption mechanism 400 is also included, and the negative pressure mechanism 900 includes a second negative pressure chamber 901 and an adsorption mold, and the adsorption mold includes an adsorption area and a non-adsorption area, and the adsorption area passes through the adsorption mold and is connected to the second negative pressure chamber 901, and the adsorption area corresponds to the reserved area 406, and the non-adsorption area corresponds to the absorption and desorption zone 403. In this embodiment, the negative pressure mechanism 900 arranged opposite to the filler absorption and desorption mechanism 400 can achieve accurate absorption and desorption of the area of ​​the composite core 1 corresponding to the absorption and desorption zone 403, avoiding the influence on the surrounding area. Specifically, a non-adsorption area is set on the negative pressure mechanism 900 corresponding to the absorption area 403 of the filler absorption mechanism 400, and an adsorption area is set on the negative pressure mechanism 900 corresponding to the reserved area 406 of the filler absorption mechanism 400; when the absorption area 403 of the filler absorption mechanism 400 absorbs liquid and filler from the corresponding area of ​​the composite core 1, the non-adsorption area corresponding to the negative pressure mechanism 900 corresponds to the area, and only the absorption area 403 of the filler absorption mechanism 400 generates an adsorption force on the area, thereby removing the absorbed liquid. The filler is adsorbed to the adsorption zone 403; and the adsorption zone of the negative pressure mechanism 900 provides negative pressure suction in the region of the composite core 1 corresponding to the reserved region 406 of the filler adsorption mechanism 400. The negative pressure suction in this region is opposite to the negative pressure suction in the adsorption zone 403, so that the liquid-absorbing filler in this region of the composite core 1 is sucked away by the adsorption zone 403, effectively avoiding the region from being affected by the suction of the adsorption zone 403, and ensuring that the shape of the guide groove 1-1 formed by the composite core 1 is basically consistent with the shape of the adsorption zone 403. The specific negative pressure mechanism 900 can also be in the form of an adsorption roller, with a hollow second negative pressure bin 901 formed in its center, and the adsorption zone and non-adsorption zone formed on its surface. During the rotation process, the adsorption zone corresponds to the reserved region 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 filler is exposed at the incision, which may easily cause leakage of the absorbent filler. In some embodiments, the model area also includes a partition area 404, which passes through the flow guide mold and is connected to the first negative pressure chamber 401. The partition area 404 extends along the width direction of the composite core 1, and the length of the partition area 404 is not less than the width of the composite core 1. The partition area 404 is located at both ends of the absorption and removal area 403. The absorbent filler at the corresponding position of the composite core 1 is absorbed by the partition area 404, that is, there is no absorbent filler in this area, forming a partition groove 1-2. This area can be used to divide the composite core 1 into individual core units. This area only contains adhesive, which will not expose the absorbent filler and will not cause the filler leakage problem. Figure 6 and 7 shown.

[0049] The first negative pressure chamber 401 can be directly connected to a recovery device to collect the liquid-absorbing filler sucked away by the filler suction and removal mechanism 400.

[0050] like Figure 4 and 5 As shown, as an improvement of the above-mentioned filler suction and removal mechanism 400, in some embodiments, the surface of the suction and removal mold 402 is coated with an isolation net, the mesh size of the isolation net is smaller than the size of the liquid-absorbing filler, and a recovery suction port 405 is also provided on one side of the filler suction and removal mechanism 400. The isolation net can prevent the liquid-absorbing filler from being absorbed into the first negative pressure chamber 401, but is absorbed on the isolation net, and then the liquid-absorbing filler on the isolation net is sucked away and collected through the recovery suction port 405. Specifically, the isolation net can be coated on the surface of the adsorption roller.

[0051] like Figure 1 ,3-5, in some embodiments, the glue applying mechanism includes a first glue applying mechanism 201 for applying glue to the bottom surface of the upper layer material 10, a second glue applying mechanism 202 for applying glue to the lower surface of the middle layer material 20, and a third glue applying mechanism 203 for applying glue to the upper surface of the lower layer material 30. The glue applying mechanism applies glue to the upper layer material 10, the middle layer material 20, and the lower layer material 30, which can not only effectively bond the three layers of materials together, but also effectively bond the applied liquid-absorbing filler.

[0052] like Figure 1 ,3-5, specifically, the composite mechanism 500 can be a hot pressing composite mechanism 500, and then the composite core 1 is thermally composited. A folding mechanism 501 is also provided between the composite mechanism 500 and the second bonding position 802, for folding the lower layer material 30 and the upper layer material 10, specifically folding the upper layer material 10 upwards, and folding the lower layer material 30 upwards, so as to form a rim on the side of the composite core 1, as shown in FIG. Figure 6 and 7 As shown, avoid leakage of the suction filler.

[0053] The present invention also provides a manufacturing process for a composite core 1, wherein an upper layer material 10, an intermediate layer material 20 and a lower layer material 30 are unwound, an adhesive is applied to the surface of the upper layer material 10, the intermediate layer material 20 or the lower layer material 30, a liquid absorbent filler is applied between the upper layer material 10 and the lower layer material 30, a filler absorption mechanism 400 is used to selectively absorb and remove the applied liquid absorbent filler, and then the upper layer material 10, the intermediate layer material 20 and the lower layer material 30 are composited.

[0054] like Figure 6 and 7 As shown, the prepared composite core 1 has diffusion and permeability properties due to the guide groove 1-1, and the liquid absorption speed can be greatly improved. After absorbing liquid, the liquid absorption filler expands. Since the liquid absorption filler in the guide groove 1-1 area of ​​the composite core 1 is sucked away, the cross-sectional area of ​​the guide groove 1-1 area is smaller than that of other areas, which has a liquid conduction effect and can play a better role in diversion; at the same time, the guide groove is bonded by an adhesive and will not expand, which plays a role in fixing the liquid absorption filler, ensuring that the composite core 1 will not have lumps and fractures after multiple washings. In addition, by setting the partition area 404, when the composite core 1 is divided, the applied liquid absorption filler will not leak, which increases the life of the core cutter while saving the use of filler and reducing costs.

[0055] Although the disclosure is disclosed as above, the protection scope of the disclosure is not limited thereto. Those skilled in the art may make various changes and modifications without departing from the spirit and scope of the disclosure, and these changes and modifications will fall within the protection scope of this application.
