具体实施方式
如图1所示，本实用新型包括包括竖直面板1、固定在竖直面板1上的按封口膜2输送方向依次设有轴心线互相平行的放膜辊3、导向辊一4、导向辊二5、导向辊三6、导向辊四7、输送对辊8和收卷辊9，还包括封口膜2的推送装置和转移装置。
所述放膜辊3通过支架30竖直固定在竖直面板1的上方。
为了使得封口膜2展平，导向辊一4、导向辊二5和导向辊三6呈“7”形分布，让封口膜2的行程变长，利于舒展、平整。
导向辊四7设于导向辊三6的后方，导向辊四7和导向辊三6的轴心线在同一水平面。
推送装置设于导向辊三6和导向辊四7的下方，封口膜2依次通过导向辊三6、推送装置的前端、推送装置的后端和导向辊四7，封口膜2经导向辊四7转向后送入输送对辊8。
输送对辊8设于导向辊四7的上方，所述收卷辊9设于输送对辊8的上方。
封口膜2的转移装置设于推送装置前方的竖直面板1边缘。
在本实施例中，推送装置为一个水平放置的双向气缸10，双向气缸10的活塞杆一11在水平直线方向上往返运动，活塞杆一11的轴心线与竖直面板1的表面平行。
在活塞杆一11前端为可伸至转移装置正下方的推头12，用于将封口膜2送至转移装置的正下方。
在本实施例中，为了保证封口膜2不被推头12表面磨损，同时保证封口膜2在推头12上的部分的封口膜片保持平整，推头12的上表面光滑且俯视投影为矩形，便于转移装置提取推头12上的封口膜片。
如图5和图6所示，推头12的底部至少在前后两端分别设有过渡辊14，位于后端的过渡辊14的底部所在水平面的高度小于双向气缸10的底部所在水平面的高度。过渡辊14可以防止封口膜2在通过推头12时被推头12的边缘划伤，同时让封口膜2不会紧贴推送装置的部件的表面，还可以降低封口膜2输送时的阻力。
活塞杆一11的后端为转向辊13，所述转向辊13的轴心线与导向辊四7的轴心线平行。
转向辊13的底部所在水平面的高度小于双向气缸10的底部所在水平面的高度。其作用如过渡辊14相似，也是防止封口膜2贴着部件底部传送，同时，转向辊3还会与推头12联动，两者同步进退，推头12向前推送封口膜2时，转向辊3收缩，当推头12向后收缩时，转向辊3向后推动封口膜2，将经过推头12的封口膜2向后拉扯。
如图1所示，转移装置包括竖直固定在竖直面板1边缘的滑台气缸15，滑台气缸15的滑台16通过滑台气缸15的活塞杆二17在竖直方向上作上下往返运动，在滑台16的前面还固定有单向气缸18，所述单向气缸18的活塞杆三19竖直向下往返运动，在活塞杆三19的底端设有转膜头20。
推送装置的推头12向前推动封口膜2直至推头位于转膜头20的正下方，再由转膜头20向下伸出并从推头12上的封口膜2提取封口膜片。
本实用新型还包括电机21，由电机21提供封口膜2输送的动力。电机21固定在竖直面板1前表面的中部，具体的，在本实施例中，导向辊一4、导向辊二5、导向辊三6、导向辊四7、输送对辊8围绕电机21设置，以利于节约空间，使整个结构更加紧凑。
如图4所示，电机21的输出轴22从竖直面板1前表面垂直穿入并从竖直面板1的后表面穿出，在输出轴22的前端设有主动轮23，输送对辊8的其中一个辊轴24从竖直面板1的后表面穿出并设有从 动轮25，主动轮23和从动轮25通过同步带26传动连接。
在从动轮25的外侧还并列设有同轴转动的主动摩擦轮27，如图7所示。
收卷辊9的辊轴从竖直面板的后表面穿出并设有从动摩擦轮28，主动摩擦轮27和从动摩擦轮28通过圆形皮带29传动连接。使用圆形皮带29进行传动，是防止收卷辊9在收卷转动时不会硬扯封口膜2。
具体的，整个工作流程如下：
首先，推头12、转膜头20都在收缩位，如图1所示。
在具体实施时，整个电路必然要利用现有技术中的各种传感器件及控制电路来控制各个气缸的具体工作时间的参数。
此时，有颜料瓶33输送至转膜头正下方，即推头12的正前方。双向气缸10开始工作，推头12向前行至前进位，即转膜头20正下方、颜料瓶33的瓶口上方，如图2所示。在推头12前进过程中，同时带动放卷辊3上的封口膜2向前输送，由于输送对辊8的作用，不会将废弃的封口膜2从收卷辊9这一端扯回来。
紧接着，滑台气缸15开始工作，滑台16向下伸出至前进位，转膜头20正好紧贴推头12的上表面上的封口膜2并提取封口膜片。
实际操作中，为了防止推头12上的封口膜2移动，在双向气缸10的上方设有压紧气缸31，压紧气缸31此时向下伸出活塞杆并通过活塞杆的头部压住封口膜2。而为了防止双向气缸10的表面不平整，可以在双向气缸10的上表面设置表面光滑平整的平板32，保护封口 膜2。
当转膜头20完成封口膜片的提取后，推头12收缩至收缩位，转向辊13同步移动至前进位，即向后伸出，将因推头12收缩而松弛的封口膜2向后推送，拉紧。此时压紧气缸31保持前进位，将封口膜2压紧在双向气缸10上，防止转向辊13在向后推动时从放卷辊3拉出封口膜2。
待推头12在到达收缩位后，滑台16保持前进位，单向气缸18开始工作，活塞杆三19向下伸出，将转膜头20送至颜料瓶33的瓶口，进行封口作业，如图3所示。
封口完成后，移入下一个颜料瓶，再重复上述步骤。
