本发明的有益效果是:
本发明提供一种防侧漏纸尿裤及其加工生产设备,通过面层、吸水芯体、第一侧翼及第二侧翼、横拉片、亲肤层的结构组合设计,构成一种防侧漏纸尿裤,此防侧漏纸尿裤通过两个竖立折沿与横拉片的横拉设计,使在吸水芯体的左右两侧构成稳定结构的第一导流侧槽、第二导流侧槽,本发明的两个导流侧槽的结构不易出现因使用者穿带后活动挤压而下陷消失,并且本发明还对亲肤层设计了进水通道及多个侧流道,使液体会直接穿过亲肤层达到横拉片中部,减少亲肤层对液体的吸取时间,而横拉片左右两侧设计了各个第一进水道及各个第二进水道,使在横拉片顶面出现侧流的液体能够直接排入第一导流侧槽、第二导流侧槽内被吸水芯体从左右两侧面进行吸收储存,并且第一导流侧槽、第二导流侧槽的外侧槽壁还有防渗漏保护设计,使纸尿裤的防侧漏性能整体提升。
本发明还提供了对第一侧翼、第二侧翼上的两个竖立折沿外侧面与横拉片进行横向热合加工生产的折边热合设备,通过纵向输送组件可以使提前贴合的成型材料进行纵向前后送输,方便抵压组件上的第一抵压头与第二抵压头对齐套入第一导流侧槽、第二导流侧槽槽腔中部,无需人工放料,节约人工成本;
而折边热压机构的设计,具有先右移吸取横拉片再左移到成型材料上方的功能,还具有对横拉片左右边侧折弯功能,使横拉片自动形成两个贴合于两个竖立折沿外侧的内倾斜侧沿,在通过抵压组件的张开作用,使第一抵压头、第二抵压头与两个下插的折边斜插板协同配合进行加热挤压热合作业,使竖立折沿均能呈向外倾斜的状态与横拉片进行热合固定,从而确保成型后的第一导流侧槽、第二导流侧槽外侧壁的竖立折沿都能保持向外倾斜状态,这是确保使用后第一导流侧槽、第二导流侧槽不会出现挤压严重变形的关键,本设备加工生产简便高效,加工放料无需手工操作,自动化程度高。

工作原理:
纸尿裤1的使用方式,当使用者穿着后,这时使用者裤档会与亲肤层16进行相贴,而在吸水芯体12对中部支撑下,横拉片15中部不会被挤压下陷,这样通过横拉片15横向拉住两个侧翼的竖立折沿131上端,就能使第一导流侧槽17与第二导流侧槽18保持住形状;
另外当液体流出后,会直接穿过进水通道161、多个侧流道162流入横拉片15中部被吸取并被吸水芯体12吸收储存,而在横拉片15顶面上的一部分液体会跟随使用者的侧躺或不规率活动出现侧流,这时侧流的液体会通过各个第一进水道151及各个第二进水道152直接流入第一导流侧槽17与第二导流侧槽18内,因横拉片15为无纺布+PE薄膜的防侧渗透设计,因此在第一导流侧槽17与第二导流侧槽18内的液体只会被吸水芯体12从左右两侧面吸收储存;
另外吸水芯体12吸收到足量的液体体积发大后,这时两个竖立折沿131就能起到对吸水芯体12左右两侧的防侧渗保护,使吸水芯体12体积发大后被挤压到不会出现侧边渗漏问题,通过上述功能设计让纸尿裤1的防侧漏性能提升。
折边热合设备2的加工生产方式,首先需把吸水芯体12、第一侧翼13与第二侧翼14提前通过现有设备贴合成型在一起,然后通过现有设备输送及现有捉手机构把贴合成型的材料捉取到第二吸盘组44的吸盘板上被吸附,然后通过第二滑动器42于纵轨43上带动移料板41后移,这样贴合成型材料会移到抵压组件5下方,这时两个抵压柱523会分别纵向穿入第一导流侧槽17与第二导流侧槽18的槽腔中部,然后折边热压机构6上的第一吸盘组65先通过第一滑动器62于横轨61上右移吸取横拉片备料箱组7内的一张横拉片15,再进行左移到要贴合成型材料的上方,需说明的是这时的两个折边组件为上升状态,然后通过第一升降器63下降,使横拉片15下降到与两个竖立折沿顶端间隙贴合,然后通过两个折边组件上的第二升降器662同步下降,使两个折边斜插板663斜向下插,对横拉片15的左右边侧进行折弯分别贴于两个竖立折沿的外侧,然后通过双头伸缩器54左右横向伸出,使两个两个抵压柱523张开,分别抵压两个竖立折沿的内侧,并在加热片665对折边斜插板663加热作用下,使横拉片15的两个折弯边侧与左右竖立折沿被加热后的各个热压凸粒6634与抵压垫524挤压热合在一起,上述加工状态(参考附图12),完成对横拉片15与第一侧翼13与第二侧翼14的热合加工产生作业;
需说明的是,当两个抵压柱523张开在做挤压时,主要的受力点在横滑块521套于第一横滑槽511上,这样就能确保抵压柱523不会出现在长期使用挤压受力而导致纵向歪斜问题,另外抵压垫524为耐高温橡胶材质设计,使在与各个热压凸粒6634进行挤压热合时不会出现硬碰硬挤压,从而造成设备的热合端损坏或变形问题;
另外需说明的是,折边斜插板663的受力点在各个防脱卡槽646与各个防脱卡沿6633的卡套处,因此折边斜插板663在受横向作用力时,会一直保持原有的倾斜角度。
