进一步的，所述机架上位于切割装置的前端设有冷却辊压机构，所述机架上位于切割装置的后端设有加热辊压机构。
进一步的，所述加热辊压机构包括间隔设置的定速辊组及变速辊组，所述定速辊组与冷却辊压机构同步运行，所述变速辊组以定速辊组的运行速度的50％～150％变化。
通过采用前述技术方案，本发明的有益效果是：本方案的设置，可以形成上基材、弹性膜、下基材复合的弹性片材，其复合采用超声波装置进行，在弹性片材上形成点粘的状态，并形成焊接点，各焊接点形成多条间隔的区隔线，并且通过设置有多个的切割部，多个的切割部在相邻的两个区隔线之间形成多个的切割单元。切割部包括上切割部、左切割部、下切割部、右切割部，从而可以对应在弹性片材上形成对应的结构。而且由于弹性膜处于横向拉伸状态，会使得弹性膜在上切割部、下切割部、左切割部、右切割部处形成扁平状的透气孔，这种透气孔由于拉伸的状态会形成扁平状，其大小往往和竖向的切割长度有关。上切割部、下切割部的竖向长度通常来说设置成1.5～5mm，左切割部、右切割部的竖向长度通常来说设置成0.5～2mm，上切割部或下切割与左切割部或右切割部的比值通常为2～3：1。至于上切割部、下切割部、左切割部、右切割部的宽度当然是越小越好，其成型方式可以采用切割或其他手段，采用超声波焊接的方式，并且实现穿透，可以形成较好的成型。采用超声波焊接后，也可以使得上层无纺布、下层无纺布会形成粘合，也即在上切割部、下切割部、 左切割部、右切割部的位置处形成焊接孔，这样透气孔会在该位置展开，从而会使得透气的效果更好。
本方案通过慢速驱动辊、快速驱动辊的设置，可以使得弹性膜实现有效的延展，其拉伸的倍率可以通过慢速驱动辊、快速驱动辊的速度比来实现调节。而后在复合后通过超声波装置进行点粘，并在点粘后进行切割，从而有效实现在弹性膜上形成透气孔，其切割是通过特定的方式进行，从而可以使得在弹性膜上的透气孔在弹性作用下拉伸，形成扁平状，从而使得透气的效果良好，而且由于是在拉伸状态下进行的切割，这种切割后的拉伸就基本处于较为极限的状态，也就是说切割后的保持状态就基本等于穿着时的状态。如此设置，可以更方便于参数的设置，从而使得弹性片材的成型准确率更高，成型效果更好。
进一步的，各切割单元的左切割部、右切割部的数量均为两个，上切割部、下切割部、左切割部、右切割部处的透气孔，形成较好的透气结构。进一步的，第一斜线、第二斜线的设置，可以形成较好的排列方式，实现较好的切割单元的排布，从而实现有效的透气。进一步的，区隔线呈倾斜状，可以形成更好的分布效果，在横向拉伸的时候，通过这样斜向的限制，可以实现更好的稳定。通过第一连线和区隔线的平行，使得各透气孔可以呈现更好的拉伸状态。这样的设置，可以有效控制各个透气孔的拉伸成型。所述区隔线与水平面的夹角为25－35度，所述第一连线与最接近的区隔线之间的距离为2.2－2.7mm，这样的数值设置，是一个较佳的范围，可以形成合理的间隔分布。一个切割单元的上切割部、左切割部、下切割部、右切割部形成一菱形，也是为了实现有效的分布。上基材、下基材为无纺布材料，配合上弹性膜，从而可以实现更好的透气效果，而且具有良好的弹性伸缩性能。由于是一次性卫生用品，其寿命的需求不高，切割弹性膜的破坏性操作并不会形成不好的状况。
进一步的，冷却辊压机构、加热辊压机构的设置，其目的在于，在切割前使得弹性膜冷却，使其硬度增大，从而便于切割，且使得切割效果更好，形成的切割部更准确。而后进行加热，使得弹性膜基本回复原有的柔性状态，减少对于弹性膜的影响。而且通过冷却辊压机构、加热辊压机构的设置，可以形成有效的夹持稳定，避免因为切割后导致弹性膜的突然拉伸。冷却辊压机构、加热辊压机构在设置时，应尽量靠近切割装置，从而使得弹性膜在经历切割之后，不会有较大的弹性变化，使得切割更稳定，切割的部位更精准。
另外，所述加热辊压机构包括间隔设置的定速辊组及变速辊组，所述定速辊组与冷却辊压机构同步运行，所述变速辊组以定速辊组的运行速度的50％～150％变化。这样设置的目的在于，可以有效减少切割时的切割不完全，通过差速的输送，可以使得弹性膜会产生拉伸，从而使得透气孔会再次被拉伸，从而减少切割不完全的状态。变速辊组的速率变化呈现周期性，从而可以满足其输送材料的频率与定速辊组是基本一致的。而这里所产生的偏差会由张力缓存机构、输出驱动辊机构来进行消除。

上述的机构均为本领域的常规机构，具体结构均已有公开，可以参考本申请人的相关专利，仅有超声波装置95以及切割装置97需要有特定的点位排列。其中，切割装置97可以采用超声波机构，采用超声波机构时，其可以在片材上一次性形成多个切割单元，可以参考图3所示，在相邻的两条区隔线之间的切割区域的多个切割单元形成了最基本的焊接单元。另外，也可以采用上切割辊与下底辊配合。上切割辊上的刀刃的设置，也可以参考图3所示，在相邻的两条区隔线之间的切割区域的多个切割单元形成了一个标准切割单元，多个标准切割单元在上切割辊的辊面上均匀分布。切割单元6的上切割部61、下切割部62、左切割部63、右切割部64即为切割装置97的上切割部、下切割部、左切割部、右切割部。切割装置的表现形式由图3可以得到更好的展现。
再参考图6，所述机架上位于切割装置97的前端设有冷却辊压机构971，所述机架上位于切割装置97的后端设有加热辊压机构。所述加热辊压机构包括间隔设置的定速辊组972及变速辊组973，所述定速辊组972与冷却辊压机构 971同步运行，所述变速辊组973以定速辊组972的运行速度的50％～150％变化。本方案中的冷却辊压机构971、定速辊组972及变速辊组973均为常规的两个上下辊配合的结构，为常规技术手段，不同在于转速、加热、冷却的变化，以及所要实现的目的。
本方案的设置，可以形成上基材、弹性膜、下基材复合的弹性片材，其复合采用超声波装置进行，在弹性片材上形成点粘的状态，并形成焊接点，各焊接点形成多条间隔的区隔线，并且通过设置有多个的切割部，多个的切割部在相邻的两个区隔线之间形成多个的切割单元。切割部包括上切割部、左切割部、下切割部、右切割部，从而可以对应在弹性片材上形成对应的结构。而且由于弹性膜处于横向拉伸状态，会使得弹性膜在上切割部、下切割部、左切割部、右切割部处形成扁平状的透气孔，这种透气孔由于拉伸的状态会形成扁平状，其大小往往和竖向的切割长度有关。上切割部、下切割部的竖向长度通常来说设置成1.5～5mm，左切割部、右切割部的竖向长度通常来说设置成0.5～2mm，上切割部或下切割与左切割部或右切割部的比值通常为2～3：1。至于上切割部、下切割部、左切割部、右切割部的宽度当然是越小越好，其成型方式可以采用切割或其他手段，采用超声波焊接的方式，并且实现穿透，可以形成较好的成型。采用超声波焊接后，也可以使得上层无纺布、下层无纺布会形成粘合，也即在上切割部、下切割部、左切割部、右切割部的位置处形成焊接孔，这样透气孔会在该位置展开，从而会使得透气的效果更好。
本方案通过慢速驱动辊、快速驱动辊的设置，可以使得弹性膜实现有效的延展，其拉伸的倍率可以通过慢速驱动辊、快速驱动辊的速度比来实现调节。而后在复合后通过超声波装置进行点粘，并在点粘后进行切割，从而有效实现在弹性膜上形成透气孔，其切割是通过特定的方式进行，从而可以使得在弹性 膜上的透气孔在弹性作用下拉伸，形成扁平状，从而使得透气的效果良好，而且由于是在拉伸状态下进行的切割，这种切割后的拉伸就基本处于较为极限的状态，也就是说切割后的保持状态就基本等于穿着时的状态。如此设置，可以更方便于参数的设置，从而使得弹性片材的成型准确率更高，成型效果更好。
进一步的，各切割单元的左切割部、右切割部的数量均为两个，上切割部、下切割部、左切割部、右切割部处的透气孔，形成较好的透气结构。进一步的，第一斜线、第二斜线的设置，可以形成较好的排列方式，实现较好的切割单元的排布，从而实现有效的透气。进一步的，区隔线呈倾斜状，可以形成更好的分布效果，在横向拉伸的时候，通过这样斜向的限制，可以实现更好的稳定。通过第一连线和区隔线的平行，使得各透气孔可以呈现更好的拉伸状态。这样的设置，可以有效控制各个透气孔的拉伸成型。所述区隔线与水平面的夹角为25－35度，所述第一连线与最接近的区隔线之间的距离为2.2－2.7mm，这样的数值设置，是一个较佳的范围，可以形成合理的间隔分布。一个切割单元的上切割部、左切割部、下切割部、右切割部形成一菱形，也是为了实现有效的分布。上基材、下基材为无纺布材料，配合上弹性膜，从而可以实现更好的透气效果，而且具有良好的弹性伸缩性能。由于是一次性卫生用品，其寿命的需求不高，切割弹性膜的破坏性操作并不会形成不好的状况。
进一步的，冷却辊压机构、加热辊压机构的设置，其目的在于，在切割前使得弹性膜冷却，使其硬度增大，从而便于切割，且使得切割效果更好，形成的切割部更准确。而后进行加热，使得弹性膜基本回复原有的柔性状态，减少对于弹性膜的影响。而且通过冷却辊压机构、加热辊压机构的设置，可以形成有效的夹持稳定，避免因为切割后导致弹性膜的突然拉伸。冷却辊压机构、加热辊压机构在设置时，应尽量靠近切割装置，从而使得弹性膜在经历切割之后， 不会有较大的弹性变化，使得切割更稳定，切割的部位更精准。
另外，所述加热辊压机构包括间隔设置的定速辊组及变速辊组，所述定速辊组与冷却辊压机构同步运行，所述变速辊组以定速辊组的运行速度的50％～150％变化。这样设置的目的在于，可以有效减少切割时的切割不完全，通过差速的输送，可以使得弹性膜会产生拉伸，从而使得透气孔会再次被拉伸，从而减少切割不完全的状态。变速辊组的速率变化呈现周期性，从而可以满足其输送材料的频率与定速辊组是基本一致的。而这里所产生的偏差会由张力缓存机构、输出驱动辊机构来进行消除。
此外，术语“第一”、“第二”仅用于描述目的，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括一个或者更多个该特征。在本发明的描述中，“多个”的含义是两个或两个以上，除非另有明确具体的限定。
