一种快渗透气吸收性物品及其制备方法
技术领域
本发明涉及一次性卫生用品领域，尤其涉及一种快渗透气吸收性物品及其制备方法。
背景技术
纸尿裤主要是针对婴儿设计的一种护理品，其使用方便，容易更换，大大减轻了婴儿母亲的护理负担。目前大多数纸尿裤尿液下渗吸收速度赶不上尿液速度，容易往外侧漏，弄湿裤子，效果差，设计师们为了防止侧漏就将纸尿裤侧围设计密封的，纸尿裤密封，透气性，使用舒适性差，并且容易滋生细菌，皮肤不舒适，影响婴儿健康。
中国专利号：201420101847.4公开了一种纸尿裤，从上而下依次叠设有表层无纺布、导流层、复合芯体、木浆高分子层和透气复合底膜和两侧的拒水无纺布包围层，所述导流层、复合芯体、木浆高分子层的两外侧由侧边无纺布包围，所述表层无纺布表面上设有利于尿液快速扩散的凹凸纹，所述复合芯体由3～5层膨化纸、无纺布、SAP层叠置而成，所述透气复合底膜由透气膜和底层无纺布通过热熔胶粘结而成，所述拒水无纺布包围层边缘上并排拉设有两条橡皮筋，所述拒水无纺布包围层上布满透气孔。该纸尿裤通过表面无纺布设有凹凸纹，增大表面积，有助于防止尿液来不及下渗就往外侧漏，并且纸尿裤尿湿后，不易紧贴在身上。
中国专利号：201520529781.3公开了一种带压花锁水凹槽结构的婴儿纸尿裤，包括外表面，与使用者皮肤相接触的内表面，设置在所述内表面与外表面之间用于吸收尿液的芯体，所述内表面与芯体上压制有压花锁水凹槽；所述压花锁水凹槽，包括：沿着纸尿裤的尾端往前端方向，往左设置3条或3条以上左侧曲线，往右对称设置3条或3条以上右侧曲线，左侧曲线和右侧曲线纵向轴对称，左侧曲线和右侧曲线相互交叉，形成若干菱形锁水凹槽；左侧曲线尾端曲线部分形成一个个弧形锁水凹槽，这些凹槽共同形成左侧波浪形线；右侧曲线尾端曲线部分形成一个个弧形锁水凹槽，这些凹槽共同形成右侧波浪形线；左侧波浪形线和右侧波浪形线轴对称，形成两道防线。该纸尿裤通过左侧曲线和右侧曲线尾端曲线设计，形成的左侧波浪形线和右侧波浪形线，这样的设计，有效避免了以往直线条纹因线条直接延伸到立体护围边缘而产生侧漏情况，并且左侧曲线和右侧曲线相互交叉，形成的锁水凹槽给予尿布芯体充足的吸收尿液时间，实现缓冲锁水的作用。
但是，上述设置的凹凸纹、棱形锁水凹槽和弧形锁水凹槽均是通过吸收芯成型后再通过压辊挤压成型，使其材质压实形成凹槽，该凹槽处的下渗速度慢，起到导流的作用，使得尿液快速流动到纸尿裤的低处聚集，降低使用舒适性，因此，需要研发一款下渗速度快、透气性好的吸收性物品。
发明内容
因此，针对上述的问题，本发明提供一种快渗透气吸收性物品及其制备方法，它主要解决了现有技术中吸收性物品的下渗速度慢、透气性差的问题。
为实现上述目的，本发明采用了以下技术方案：一种快渗透气吸收性物品，包括吸收芯体，所述吸收芯体包括膨松无纺布，所述膨松无纺布的上、下表面分别设置有第一sap层和第二sap层，所述第一sap层上复合粘合有第一无尘纸，所述第二sap层上复合粘合有第二无尘纸，所述第一sap层上设置有至少一个第一通槽，所述第二sap层上设置有至少一个第二通槽，所述第一通槽和第二通槽的宽度均为0.1mm～40mm。
进一步的，所述第一通槽和第二通槽均为长条状或者S形状。
进一步的，所述第一通槽和第二通槽的位置相对应。
进一步的，所述第一通槽和第二通槽均设置在吸收芯体的中部，且沿吸收芯体的长度方向分布。
进一步的，所述吸收芯体的制备方法为：
1)第一放卷装置对膨松无纺布进行放卷，再通过过渡辊进行输送到第一下料装置的下侧；
2)sap材料通过第一下料装置下落到膨松无纺布的上表面上形成第一sap层，同时第一sap层上的第一通槽通过第一下料装置上的挡板隔绝sap材料掉落到膨松无纺布的上表面上形成；
3)通过第一喷胶装置对第一sap层的上表面进行喷胶处理；
4)第二放卷装置对第一无尘纸进行放卷，并且输送到喷胶后的第一sap层上复合；
5)复合后的材料通过过渡辊传动反转，将膨松无纺布的下表面翻转至朝上；
6)sap材料通过第二下料装置下落到膨松无纺布的另一上表面上形成第二sap层，同时第二sap层上的第二通槽通过第二下料装置上的挡板隔绝sap材料掉落到膨松无纺布的上表面上形成；
7)通过第二喷胶装置对第二sap层的上表面进行喷胶处理；
8)第三放卷装置对第二无尘纸进行放卷，并且输送到喷胶后的第二sap层上复合；
9)经过裁切装置裁切成型。
上述所述第一下料装置和第二下料装置均包括下料壳体，所述下料壳体的上部设置有进料口，所述下料壳体的下部设置有储料箱，所述储料箱的下表面设置有出料口，所述储料箱上位于出料口处设置有挡板，所述出料口的下侧设置有下料辊，所述下料辊的圆周外表面上设置有下料槽。
进一步的，所述挡板包括固定设置在储料箱上的基板，所述基板的左右两侧分别可滑动地设置有隔板，所述基板上设置有电动机，所述电动机的输出轴上设置有蜗轮，所述基板上可转动地设置有蜗杆，所述蜗杆的两端均设置有螺纹杆，且螺纹杆的螺纹旋向相反，两所述隔板上设置与螺纹杆相配合的螺纹套。
通过采用前述技术方案，本发明的有益效果是：本快渗透气吸收性物品，通过在膨松无纺布的上下表面分别设置第一sap层和第二sap层，增加了吸收芯体的吸收量以及吸收速度，并且在第一sap层和第二sap层上复合粘合第一无尘纸和第二无尘纸，有效的复合上sap材料，使得吸收芯体的结构稳定，通过在第一sap层和第二sap层上分别设置第一通槽和第二通槽，使得位于第一通槽和第二通槽处的第一无尘纸和第二无尘纸分别直接与膨松无纺布接触，尿液透过无尘纸向下渗透，增加渗透速度，防止sap吸收尿液后膨胀，材料的气孔减少，增加了吸收芯体的透气性和舒适性；进一步的，第一通槽和第二通槽均为长条状或者S形状，增加吸收芯体下渗的均匀性，使得尿液更好的分布第一sap层和第二sap层上，增加吸收芯体的舒适性；进一步的，第一通槽和第二通槽的位置相对应，增加尿液的下渗速度；进一步的，sap材料直接下落到膨松无纺布上，再通过喷胶复合无尘纸，减少了膨松无纺布与sap材料的喷胶工艺，使得sap材料更好的复合在膨松无纺布的空隙上，增加生产效率，降低加工成本，并且减少胶水的实用量，降低sap材料吸收胶水的容量，充分发挥sap材料的吸水性能，通过挡板挡住sap材料的下落到下料辊上，再粘附在膨松无纺布上，使得sap材料的贴附无纺布上均匀，通过挡板隔断sap材料的下料形成通槽，加工效果好，提高生产效率；进一步的，基板上的电动机带动蜗轮转动，从而驱动蜗杆自传，设置在蜗杆两端的螺纹杆跟随转动，从而驱动螺纹套转动，带动两个隔板相向或者相反运动，进而调节挡板的宽度，使得通槽的宽度可变。

本快渗透气吸收性物品，通过在膨松无纺布5的上下表面分别设置sap层3和sap层4，增加了吸收芯体1的吸收量以及吸收速度，并且在sap层3和sap层4上复合粘合无尘纸5和无尘纸6，有效的复合上sap材料，使得吸收芯体1的结构稳定，通过在sap层3和sap层4上分别设置通槽7和通槽8，使得位于通槽7和通槽8处的无尘纸5和无尘纸6分别直接与膨松无纺布2接触，尿液透过无尘纸向下渗透，增加渗透速度，防止sap吸收尿液后膨胀，材料的气孔减少，增加了吸收芯体1的透气性和舒适性；通槽7和通槽8均为长条状，增加吸收芯体1下渗的均匀性，使得尿液更好的分布sap层7和sap层8上，增加吸收芯体1的舒适性；通槽7和通槽8的位置相对应，增加尿液的下渗速度。
参考图3、图4与图5，所述吸收芯体1的制备方法为：
1)放卷装置11对膨松无纺布1进行放卷，再通过过渡辊12进行输送到下料装置13的下侧；
2)sap材料通过下料装置13下落到膨松无纺布1的上表面上形成sap层3，同时sap层3上的通槽7通过下料装置13上的挡板14隔绝sap材料掉落到膨松无纺布1的上表面上形成；
3)通过喷胶装置15对sap层3的上表面进行喷胶处理；
4)放卷装置16对无尘纸5进行放卷，并且输送到喷胶后的sap层3上复合；
5)复合后的材料通过过渡辊传动反转，将膨松无纺布1的下表面翻转至朝上；
6)sap材料通过下料装置17下落到膨松无纺布1的另一上表面上形成sap层4，同时sap层4上的通槽8通过下料装置17上的挡板14隔绝sap材料掉落到膨松无纺布1的上表面上形成；
7)通过喷胶装置19对sap层4的上表面进行喷胶处理；
8)放卷装置20对无尘纸6进行放卷，并且输送到喷胶后的sap层4上复合；
9)经过裁切装置21裁切成型。
参考图4，所述下料装置13和下料装置17均包括下料壳体101，所述下料壳体101的上部设置有进料口102，所述下料壳体101的下部设置有储料箱103，所述储料箱103的下表面设置有出料口104，所述储料箱103上位于出料口104处设置有挡板14，所述出料口104的下侧设置有下料辊105，所述下料辊105的圆周外表面上设置有下料槽106。
sap材料直接下落到膨松无纺布1上，再通过喷胶复合无尘纸，减少了膨松无纺布1与sap材料的喷胶工艺，使得sap材料更好的复合在膨松无纺布1的空隙上，增加生产效率，降低加工成本，并且减少胶水的实用量，降低sap材料吸收胶水的容量，充分发挥sap材料的吸水性能，通过挡板14挡住sap材料的下落到下料辊105上，再粘附在膨松无纺布1上，使得sap材料的贴附无纺布上均匀，通过挡板14隔断sap材料的下料形成通槽，加工效果好，提高生产效率。
参考图5，所述挡板14包括固定设置在储料箱103上的基板141，所述基板141的左右两侧分别可滑动地设置有隔板142，所述基板141上设置有电动机143，所述电动机143的输出轴上设置有蜗轮144，所述基板141上可转动地设置有蜗杆145，所述蜗杆145的两端均设置有螺纹杆146，且螺纹杆146的螺纹旋向相反，两所述隔板14上设置与螺纹杆146相配合的螺纹套147，基板141上的电动机143带动蜗轮145转动，从而驱动蜗杆145自传，设置在蜗杆145两端的螺纹杆146跟随转动，从而驱动螺纹套147转动，带动两个隔板142相向或者相反运动，进而调节挡板14的宽度，使得通槽的宽度可变。
尽管结合优选实施方案具体展示和介绍了本发明，但所属领域的技术人员应该明白，在不脱离所附权利要求书所限定的本发明的精神和范围内，在形式上和细节上可以对本发明做出各种变化，均为本发明的保护范围。
