Description

纸尿裤弹性腰围切断机构
技术领域
本发明涉及纸尿裤的生产设备领域，尤其涉及的是纸尿裤弹性腰围切断机构。
背景技术
现有纸尿裤的腰围为弹性的，具有贴身、方便穿戴、有效防泄漏等特点，受到广泛欢迎。在目前弹性腰围纸尿裤的生产制作工艺中，为保证生产过程的，弹性层输送物料的连续性，切断机构采用的是间隔切断，保持橡筋不断裂，等弹性腰围变横时才将橡筋拉断后再进行弹性层复合。上述生产制作方法，弹性层在转移和复合不可避免地发生一定的偏差，产品的品控就达不到理想的要求。
发明内容
本发明的目的在于克服上述不足，提供一种将弹性层完全切断后转移输送的纸尿裤弹性腰围切断机构。
为实现上述目的，本发明的技术解决方案是，纸尿裤弹性腰围切断机构，包括机架、送料机构、以及可转动地架设于机架的吸附辊和刀辊；刀辊位于吸附辊的后侧，刀辊设置有轴向的刀片；吸附辊的周面分布有若干吸附孔，在吸附辊的两侧各紧贴安装有一气压室，吸附辊和两个气压室相连通，气压室设有抽气孔；送料机构位于刀辊和吸附辊的中上方，送料机构包括架于机架的圆杆、固定安装于圆杆的两根支杆、可转动架于两根支杆之间的送料辊，圆杆和送料辊之间留有供纸尿裤弹性层通过的间隙。
优选的，刀辊位于吸附辊的后上方。
优选的，吸附辊沿周向分为四个区域，包括两个吸附孔分布稀疏的稀疏区和两个吸附孔分布紧密的紧密区，稀疏区和紧密区间隔设置。
优选的，吸附辊和刀辊都设置有中轴，它们的中轴的一端都伸出机架外且与相应驱动装置连接。
优选的，吸附辊的两端面分布有圆周排列的通气孔，气压室的内端面设置有与通气孔对应的弧形通气条孔。
优选的，机架的两侧都安装有用于安装吸附辊中轴端部的吸附辊内端盖和吸附辊轴承座。
优选的，机架的两侧都安装有用于安装刀辊中轴端部的刀辊内端盖和刀辊轴承座。
优选的，机架包括两块侧板、前板、后板和盖板。
通过采用上述的技术方案，本发明的有益效果是：采用刀辊将纸尿裤的弹性层完全切断再输送至变横机构，降低甚至避免弹性层在转移和复合的偏差，提高产品的质量和合格率，采用吸附辊作为底辊能够保证整片弹性层的平整性和规格统一。弹性层先通过中上方送料机构的送料辊和圆杆之间再送入吸附辊和刀辊之间，弹性层在附着于吸附辊的部分完全被切断取得整片弹性层后，弹性层断料的前端仍垂挂于吸附辊和刀辊之间，而在吸附辊的吸附作用下，弹性层断料随吸附辊的转动再绕于吸附辊表面，上述结构的设计保证弹性层切断工作自动不间断进行，提高生产效率。

具体实施方式
以下结合附图和具体实施例来进一步说明本发明。
本发明中所提到的方向用语，例如：上、下、左、右、前或后等，仅是参考附加图式的方向。因此，使用的方向用语是用来说明并非用来限制本发明。
如图1-2所示，纸尿裤弹性腰围切断机构，包括机架1、周面设有吸附孔24的吸附辊2、带有轴向刀片34的刀辊3和送料机构，吸附辊2周面沿周向分为四个区域，分布为两个A区和B区，B区为吸附孔24分布稀疏的稀疏区，A区为吸附孔24分布紧密的紧密区，A区和B区沿周向间隔设置。 机架1包括有位于左右两侧的侧板13、前端的前板11、后端的后板12、底部的底座14，以及位于上端的盖板15。刀辊3设置于吸附辊2后上方，送料机构安装于刀辊3和吸附辊2的中上方。
送料机构包括圆杆41、两根支杆42和送料辊43，圆杆41不可转动地固定架设于机架1的两侧板13之间，两根支杆42固定于圆杆41的中部，送料辊43可转动地架于两根支杆42之间，圆杆41和送料辊43之间留有供纸尿裤弹性层穿过的间隙6，在无其他外力作用下，纸尿裤弹性层不会从间隙6滑出。
吸附辊2中间带有吸附辊中轴21，吸附辊中轴21的端部是通过吸附辊内端盖22和吸附辊轴承座23可转动地安装于机架1的侧板，吸附辊内端盖22和吸附辊轴承座23相互匹配地安装于机架1的侧板13。刀辊3的中间也带有刀辊中轴31，刀辊中轴31的端部是通过刀辊内端盖32和刀辊轴承座33可转动地安装于机架1的侧板，刀辊内端盖32和刀辊轴承座33相互匹配地安装于机架1的侧板13。
本结构中吸附辊2的吸附辊中轴21和刀辊3的刀辊中轴31的一端都伸出机架1的侧板13外，该端分别与相应驱动装置（未示出）连接，由相应驱动装置来驱动吸附辊2和刀辊3转动，通过联动机构和齿轮结构让吸附辊2和刀辊3共用一台电机，也可以吸附辊2和刀辊3分别单独使用一台电机。
在吸附辊2的两侧各紧贴安装有一气压室5，在吸附辊2的两个端面设有圆周分布的通气孔25，在气压室5的内侧则设在有弧形通气条孔52，通气孔25和通气条孔52相对应实现吸附辊2和气压室5相连通，气压室5还设置有抽气孔51，抽气孔51与抽真空装置（未示出）相连接。
纸尿裤弹性层先穿过间隙6再送入吸附辊2和刀辊3之间，吸附辊2吸附弹性层并拉动弹性层随之旋转，等弹性层附着于吸附辊2的长度达到要求时，刀辊3的刀片34旋转至吸附辊2和刀辊3的相切线并切断弹性层，而位于本切断机构前端的变横机构7的吸附板紧贴吸附辊2从而将整片弹性层吸附过去（具体见图3），在上述过程中，与变横机构7吸附板紧贴的刚好是A区，减少对变横机构7吸附板吸附力的要求。在切除前端整片弹性层后，余下的弹性层断料不会从间隙6滑出而是继续垂挂于吸附辊2和刀辊3之间，在吸附辊2的吸附作用下，此时吸附辊2与弹性层断料对应的部位B区增强吸附辊2的吸附力，弹性层断料随吸附辊2的转动绕于吸附辊2的表面，然后再由刀辊3切断并由变横机构7将整片弹性层吸附过去，如此不间断重复上述动作，工作效率高。
以上所述的，仅为本发明的较佳实施例而已，不能限定本发明实施的范围，凡是依本发明申请专利范围所作的均等变化与装饰，皆应仍属于本发明涵盖的范围内。
