 具体实施方式
以下结合说明书附图和具体实施例对本发明作进一步详细说明。
实施例一
图1至图7示出了本发明连续生产吹灌封设备的一种实施例，本实施例的连续生产吹灌封设备，包括挤出机1、与挤出机1连接的挤出模头2、穿设于挤出模头2中的灌针3、位于挤出模头2下方的瓶头模具4、以及位于瓶头模具4下方的瓶身模具5和下夹持组件6，下夹持组件6设于第一升降机构8上，瓶头模具4和瓶身模具5设于第二升降机构9上，下夹持组件6包括一对夹板61，夹板61的内侧设有瓶身定位槽62，瓶身定位槽62下方设有瓶头定位槽63，瓶身定位槽62和瓶头定位槽63的侧边设有冷却通道64。以第一升降机构8为例，本实施例中，第一升降机构8包括伺服电机81、与伺服电机81连接的滚珠丝杆82及设于滚珠丝杆82上的丝杆螺母83，下夹持组件6与丝杆螺母83连接，使用时伺服电机81带动滚珠丝杆82旋转，丝杆螺母83在滚珠丝杆82上升降运动，下夹持组件6随丝杆螺母83同步升降，整体结构简单、可靠，运动精度高。当然在其他实施例中，第一升降机构8也可采用其他形式。第二升降机构9可与第一升降机构8结构相同，不再赘述。
该连续生产吹灌封设备，可以连续完成挤出、成型、灌装与封口工序，有利于提高生产效率，且整个生产过程中胚体10均处于封闭状态，避免了外部环境对于灌装药液的污染风险；下夹持组件6在第一升降机构8的带动下，可以上升至瓶身模具5之间（需在瓶身模具5开模之后）同时夹持固定住上方瓶体20的瓶身和下方瓶体20的瓶头，有效地避免瓶头模具4、瓶身模具5开合模时导致胚体10晃动，并且夹板61内冷却通道64通入的冷却液可以对成型后的瓶体20进行冷却，有利于保证瓶体20的一致性。
进一步地，本实施例中，瓶头模具4上方设有上夹持组件7，上夹持组件7设于第二升降机构9上。上夹持组件7与下夹持组件6配合，可以保证胚体10始终至少有一处被夹持固定住，在整个生产过程中能够有效地避免瓶头模具4、瓶身模具5开合模时导致胚体10晃动的隐患，进一步提升了设备的可靠性。
作为优选的实施例，连续生产吹灌封设备还包括用于向挤出模头2所在的区域提供洁净气体的供气部件（图中未示出，例如风机、供气管道等）。通过供气部件为挤出模头2所在的区域提供洁净的无氧气体（例如氮气或惰性气体等），保证成型、灌装和封口过程中的无菌、无氧洁净环境。
进一步地，本实施例中，夹板61连接有第一伸缩驱动件65（例如气缸、电缸、丝杆螺母副等）和第一导向杆66，第一导向杆66穿设于第一导向座67中。通过第一导向杆66与第一导向座67配合，为夹板61的开合动作提供导向作用，有利于保证运动过程顺畅及精度。
进一步地，本实施例中，上夹持组件7包括一对楔形夹块71，楔形夹块71通过第二导向杆72与第二伸缩驱动件73（例如气缸、电缸、丝杆螺母副等）连接，第二导向杆72穿设于第二导向座74中。采用楔形夹块71，机械强度高，较薄的一侧便于夹持胚体10，减少物料浪费，较厚的一侧便于连接第二导向杆72，通过第二导向杆72与第二导向座74配合，为楔形夹块71的开合动作提供导向作用，有利于保证运动过程顺畅及精度。
进一步地，本实施例中，灌针3包括灌针本体31及用于安装灌针本体31的灌针座32，灌针本体31与灌针座32之间设有冷却套管33，冷却套管33下端的侧壁上设有通孔34。可以往冷却套管33内通入冷却液，冷却液向下流动然后从通孔34流出，最后从冷却套管33与灌针座32之间的间隙离开灌针座32，流动过程中可以为灌针本体31内的药液进行保温，避免高温的胚体10对于药液的不利影响。
实施例二
图8示出了本发明连续生产吹灌封设备的使用方法的一种实施例，本实施例的连续生产吹灌封设备的使用方法，挤出机1挤出胚体10，下夹持组件6上升至瓶身模具5之间封底胚体10并向下动作，由瓶身模具5和瓶头模具4对胚体10进行瓶身和瓶头成型，同时下夹持组件6、瓶头模具4和瓶身模具5同步下降，在瓶身模具5开模后瓶头模具4开模前，下夹持组件6上升至瓶身模具5之间夹持瓶体20。
该连续生产吹灌封设备的使用方法，连续进行挤出、成型、灌装与封口工序，提高了生产效率，且整个生产过程中胚体10均处于封闭状态，避免了外部环境对于灌装药液的污染风险；下夹持组件6上升至瓶身模具5之间夹持固定住瓶体20，有效地避免了瓶头模具4、瓶身模具5开合模时导致胚体10晃动。
本实施例中，连续生产吹灌封设备的使用方法的具体步骤如下：
S1、挤出：挤出机1将塑料原料转变为塑料流体，挤出模头2将塑料流体挤出为胚体10，具体参见图7，本实施例中胚体10横截面为腰圆形封闭结构；
S2、胚体10封底：第一升降机构8带动下夹持组件6上升至瓶身模具5之间（此时瓶身模具5尚未合模），下夹持组件6夹持胚体10，第一升降机构8带动下夹持组件6随胚体10同步下降至初始位置（图8a中P0为下夹持组件6的初始位置，P0´为瓶头模具4的初始位置，也是最高位置，图8b中P1为下夹持组件6上升至瓶身模具5内的位置，也是下夹持组件6的最高位置），具体如图8a至图8c所示；
S3、瓶身成型：瓶身模具5合模并随胚体10同步下降成型出瓶身，灌针3下降至设定位置进行灌装，具体如图8d所示，灌装完成后复位；
S4、瓶头成型：瓶头模具4合模成型出瓶头，第一升降机构8带动下夹持组件6，同时第二升降机构9带动瓶头模具4和瓶身模具5随胚体10同步下降至设定位置，具体如图8e至图8g所示，图8g中瓶头模具4位于P1´位置，下夹持组件6位于P2位置，两者均为最低位置；
S5、胚体10夹持：瓶身模具5开模，第一升降机构8带动下夹持组件6上升至瓶身模具5之间，下夹持组件6夹持成型后的瓶体20，瓶头模具4开模，具体如图8g至图8j所示，需要说明的是，对于成型出的第一排瓶体20，下夹持组件6仅夹持第一排瓶体20，在后续过程中，下夹持组件6同时夹持上方一排瓶体20的瓶身和下方一排瓶体20的瓶头，或者说同时夹持上一循环瓶体20的瓶头和本循环瓶体20的瓶身；
S6、复位：第二升降机构9带动瓶头模具4和瓶身模具5上升至初始位置，第一升降机构8带动下夹持组件6移动至初始位置，具体如图8k至图8l所示，图8l与图8d中设备处于相同的状态；
S7、循环进行步骤S3至S6直至完成生产或故障停机。
进一步地，本实施例中，下夹持组件6位于瓶身模具5下方时与瓶身模具5的最大距离大于瓶头长度，具体如图8c和图8k所示，可以为下夹持组件6同时夹持上方一排瓶体20的瓶身和下方一排瓶体20的瓶头预留足够的空间，步骤S3中，瓶身模具5成型出瓶身的同时下夹持组件6打开，为下一次夹持做好准备，当然在其他实施例中，也可在步骤S4的下降过程中打开；步骤S5中，下夹持组件6上升至初始位置，步骤S6中，下夹持组件6移动距离为零，有利于简化下夹持组件6的运动过程，提高生产效率。
更进一步地，本实施例中，步骤S4中，瓶头模具4合模成型出瓶头后，上夹持组件7夹持胚体10，具体如图8f所示，然后第二升降机构9带动瓶头模具4、瓶身模具5和上夹持组件7随胚体10同步下降至设定位置；
步骤S5中，瓶头模具4开模后，上夹持组件7打开，具体如图8i和图8j所示；
步骤S6中，第二升降机构9带动瓶头模具4、瓶身模具5和上夹持组件7上升至初始位置，具体如图8k所示。
通过上夹持组件7与下夹持组件6配合，可以保证胚体10始终至少有一处被夹持固定住，在整个生产过程中能够有效地避免瓶头模具4、瓶身模具5开合模时导致胚体10晃动的隐患，进一步保证了产品的均一性。
虽然本发明已以较佳实施例揭露如上，然而并非用以限定本发明。任何熟悉本领域的技术人员，在不脱离本发明技术方案范围的情况下，都可利用上述揭示的技术内容对本发明技术方案做出许多可能的变动和修饰，或修改为等同变化的等效实施例。因此，凡是未脱离本发明技术方案的内容，依据本发明技术实质对以上实施例所做的任何简单修改、等同变化及修饰，均应落在本发明技术方案保护的范围内。
