具体实施方式
如图1-图5所示，这种泡罩装盒机推料装置包括有链条1、链轮(未画出)、环形推板导轨4、环形推纸导轨以及若干个推料单元2。每个推料单元2都包括有推料座20、推板组件21以及推纸组件22，推板组件21与推纸组件22都装在推料座20上，而推料座20与链条1连接，链条1绕于链轮上。通过主动力源的传动，链轮带动链条1转动，而链条1带动推料单元2作环形运动。为了减轻链条1的承载负荷，本发明在环形推板导轨4的两侧均设有环形导轨3，而推料座20的两端均具有移动滑座23，移动滑座23配合滑动设在环形导轨3上。这里的“配合滑动”指的是移动滑座23能在环形导轨3作环形运动。通过这种结构，整个推料单元2的重量就作用在环形导轨3上，换个角度讲就是环形导轨3承受整个推料单元2的重量，而链条1只要拉着整个推料单元2作环形运动即可，因此整个系统噪音显著降低，同时大大延长了链条1的使用寿命。
环形导轨3的形式可以有两种，相应的，移动滑座23的结构也有两种，下面具体给出两种实施例。
第一种：环形导轨3可以是凹槽形式，这种情况下，移动滑座23可以只为一个滚轮，让一个滚轮在环形的凹槽内滚动，该凹槽最好是位于侧面，让滚轮从侧面进入凹槽内，这种结构也能使移动滑座23配合滑动设在环形导轨3上，达到同样的技术效果。
第二种：环形导轨3呈条块状，这种情况下，移动滑座23包括有上滚轮230与下滚轮231，如图5与9所示，下滚轮231与上滚轮230里外抱住环形导轨3，即下滚轮231作用在环形导轨3的内环，而上滚轮230作用在环形导轨3的外环，这样移动滑座23就不会发生里外移动；而其中一端的移动滑座23还包括有左滚轮与右滚轮232，左滚轮与右滚轮232左右抱住环形导轨3，即左滚轮作用在环形导轨3的左侧面，右滚轮232作用在环形导轨3的右侧面，这样移动滑座23就不会发生左右移动。这种结构也能使移动滑座23配合滑动设在环形导轨3上，达到同样的技术效果。
在第二种环形导轨3的基础上，为了提高移动滑座23与环形导轨3抱合的稳定性，本发明的环形导轨3具有左右并排的两条环形导轨3，如图8所示；而移动滑座23具有两个前后设置的上滚轮230，如图9所示，两个上滚轮230一左一右对应作用在两条环形导轨3上，如图5所示，两个上滚轮230与一个下滚轮231从侧面看形成一个三角形，这种移动滑座23结构的好处是：一、设置两个上滚轮230可以增加移动滑座23与环形导轨3的接触面积，这样可以分担每个上滚轮230所承受的力，进而减少每个上滚轮230与环形导轨3之间的摩擦力，最终降低系统噪音，提高移动滑座23寿命；二、两个上滚轮230前后设置可以使移动滑座23以三角的形式抱住环形导轨3，三点形成一个面，这样移动滑座23在环形导轨3的弧线段能更加稳固地实现转弯。基于上述结构的移动滑座23，根据共轭凸轮原理，为了使移动滑座23能实现平稳转弯(即在转弯段，两个上滚轮230与一个下滚轮231三者均始终与环形导轨3贴合)，两条环形导轨3的转弯过渡段30的表面具有高度差。通过这种结构，移动滑座23在转弯段始终抱住环形导轨3，使移动滑座23的中心点在转弯段的运动轨迹无限接近半圆，从而使推料单元2的运动轨迹无限接近跑道型，最终保证推料单元2稳定工作。
如上面所述，链条1拉着推料单元2移动，然而随着时间的积累，链条1会被慢慢拉伸，随着链条1的拉伸，链条1将不能正常推动推料单元2工作。为了解决该问题，如图6所示，推料座20通过自适应件11与链条1连接，自适应件11的一端与链条1的轴销10铰接，而自适应件11的另一端与推料座20铰接(包括直接铰接或者间接铰接，图6中画的是铰接在一个连接座上，而该连接座与推料座20连接)。这种结构的好处是：即使链条1具有一定的拉伸，由于推料座20是限制在环形导轨3上，因此可通过推料座20拉着自适应件11，而自适应件11又拉住链条1，由此保证链条1能正常推动推料单元2工作，最终保证推板滚轮44在转弯时不会脱出环形推板导轨4。
目前市场上主流的泡罩装盒机推料装置在换规格时(不同规格的泡罩板其高度会有 差异)，推说明书用的推纸板高度也要相应变化，现有结构只能支持逐一对单个推纸组件22进行调整或更换，费时费力，而且调整高度难以统一，进而对推料入盒产生影响。
为了解决该问题，本发明在环形推板导轨4的外围设有导槽架5，如1与图2所示，该导槽架5上设有环形推纸导槽52与环形升降导槽53，如图11所示，导槽架5由上导槽架50与下导槽架51拼装而成，而上导槽架50可升降调节地安装在下导槽架51上。上导槽架50上具有环形推纸导槽上段521与环形升降导槽上段531，而下导槽架51上具有环形推纸导槽下段522与环形升降导槽下段532。环形推纸导槽上段521与环形推纸导槽下段522之间可延伸衔接，而环形升降导槽上段531与环形升降导槽下段532之间可延伸衔接：即上导槽架50升降调节时，环形推纸导槽上段521与环形推纸导槽下段522之间的间距发生变化，但是两者依然形成闭环，环形升降导槽上段531与环形升降导槽下段532也是同理。
采用上述导槽架5结构后，为了能使推纸组件22能适应这种导槽架5，推料单元2的结构也要相应作出改进，具体改进如下：如图9所示，在推料座20上安装有升降导轨24，如图10所示，该升降导轨24上可滑动设有定位滑块25，定位滑块25上安装有升降滚轮26与定位导槽27，升降滚轮26设于环形升降导槽53内；推纸组件22包括有推纸板220与推纸导杆221，推纸导杆221一端与推纸板220连接，推纸导杆221另一端连接有推纸滚轮222，推纸导杆221设于定位导槽27内，定位导槽27对推纸导杆221起到导向的作用，而推纸滚轮222设于环形推纸导槽52内。
推纸板220的高度调整原理如下：当药板的高度变高时，推纸板220的高度相应也要变高。调节时，升高上导槽架50，这时环形推纸导槽上段521与环形升降导槽上段531同时升高，由于升降滚轮26在环形升降导槽53内，定位滑块25在升降导轨24移动并上升，定位导槽27也同时升高，而由于推纸滚轮222设于环形推纸导槽52内，推纸导杆221与推纸板220也同时升高，这样推纸导杆221依然在定位导槽27内，而推纸板220调高后就能适应药板的变高。通过这种，调节推纸板220的高度就十分简单，只要调节上导槽架50的高度即可，从而降低更换药板规格后调节设备的难度，提高生产效率。
环形推纸导槽上段521与环形推纸导槽下段522的可延伸衔接可以采用多种结构，比如可以采用可拉伸的延伸导槽，通过延伸导槽来衔接上下两段，本发明给出一种更加方便的衔接方式：如图11所示，环形推纸导槽上段521的端部具有竖直的导槽延伸部54，而环形推纸导槽下段522的端部具有竖直的衔接调节槽55，该导槽延伸部54可升降地设在衔接调节槽55内。在调整上导槽架50的高度时，上导槽架50上的导槽延伸部54就在下导槽架51上的衔接调节槽55内上下竖直移动，而环形推纸导槽52依然是封闭的导槽。
同样，环形升降导槽上段531与环形升降导槽下段532的可延伸衔接可以采用多种结构，由于环形升降导槽53是沿着横向开槽，可以在侧边采用可上下移动的延伸块，通过延伸块来衔接上下两段；本发明给出一种更加方便的衔接方式：如图11与图12所示，在环形升降导槽上段531的端部具有竖直的上导槽侧壁533，环形升降导槽下段532的端部具有竖直的下导槽侧壁534，下导槽侧壁534与上导槽侧壁533左右吻合。在调整上导槽架50的高度时，上导槽架50上的上导槽侧壁533与下导槽架51上的下导槽侧壁534虽然上下距离会变化，但是两者左右还是贴合在一起，升降滚轮依然可以在上导槽侧壁533或者下导槽侧壁534上，也就是说环形升降导槽53依然是封闭的导槽。
为了能更加平稳地调节上导槽架50的位置，本发明在下导槽架51上安装有升降滑块座511，该上导槽架50上安装有直线导轨501，而升降滑块座511滑动设于直线导轨501上，在下导槽架51上还安装有调节螺杆58，该调节螺杆58与上导槽架50螺纹连接。当需要调节上导槽架50的位置时，只要转动调节螺杆58(通过手动或者电机都可以)，上导槽架50就通过直线导轨501实现上下移动，从而实现平稳调整。
当然，推板组件21包括有推板头210、推板滚轮212以及推板滑块211，如图9所示，推板滚轮212与推板头210均连接在推板滑块211上，推板滚轮212位于环形推板导轨4内，推料座20上设有定位导轨28，推板滑块211滑动设于定位导轨28上。随着推料座20作环形运动，推板滚轮212在环形推板导轨4上移动，在环形推板导轨4的导向下，推板滑块211在定位导轨28上移动，这样推板头210就实现推药板动作。
如图7与图13所示，一般情况下，推板滚轮沿着环形推板导轨4的路径进行运动，当推板滚轮212沿该路径进行运动时，推板头210能正常将药板推出；然而有时药板放置有问题，导致药板输送格栅内的某个格栅内没有药板，这时推板头210就可以不需要推出，当然推板头210也可以推出，不过由于推板头210推出的过程就是推板滚轮212走斜道的过程，而这会影响滚轮寿命。为了解决该问题，在环形推板导轨4的一侧设有推板保护导槽40，该推板保护导槽40的两端均衔接在环形推板导轨4上，推板保护导槽40与环形推板导轨4的上端衔接处设有推板变轨组件，推板变轨组件包括有推板变轨岔道41与驱动推板变轨岔道41转动的推板变轨动力源。当系统检测到某个格栅内没有药板时，推板变轨动力源就控制推板变轨岔道41转动，这样对应的某个推板滚轮210不再进入到环形推板导轨4，而是进入到推板保护导槽40，推板保护导槽40由于没有斜道，因此不会对推板滚轮210造成影响，从而增加滚轮等零件的寿命。
同样，为了延长推纸滚轮的寿命，在环形推纸导槽52的一侧设有推纸保护导槽59， 如图15所示，推板保护导槽59的两端均衔接在环形推纸导槽52上，推纸保护导槽59与环形推纸导槽59的上端衔接处设有推纸变轨组件，如图14所示，推纸变轨组件包括有推纸变轨岔道590与驱动推纸变轨岔道590转动的推纸变轨动力源。其原理与上述推板滚轮的变轨相同，这里不再赘述。
按照本发明提供的一种泡罩装盒机推料装置，通过在环形推板导轨4的两侧均设置环形导轨3，让推料座20两端的移动滑座23配合滑动设在环形导轨3上，由此让环形导轨3承载整个推料单元2重量，而链条1只负责拉动整个推料单元2运动，因此整个系统噪音大大降低，链条使用寿命更长。
