本实施例的工作过程: 图 2所示为封膜前的初始状态, 当焊盖总成 3确认合格后的输 液软袋 11由袋传送组件 1输送至封膜总成 4, 如图 3, 封膜定位机构 45动作, 对输液软 袋 11进行水平定位; 与此同时, 冲膜机构 42 的冲裁刀向上动作, 在穿行于冲膜机构 42 中的膜带 411上冲裁出膜片 14。 然后第一驱动件 432下行, 使真空吸附头 431吸取膜片 14, 第一驱动件 432再上行, 第二驱动件 433前行至输液软袋 11上方, 第一驱动件 432 再下行, 使膜片 14与输液软袋 11上的盖子 13贴合。 然后焊膜驱动件下行, 通过加热一 定温度的焊膜压头 441作用到膜片 14上,将膜片 14热合焊接到输液软袋 11的盖子 13上。 之后焊膜驱动件上行, 同时, 第一驱动件 432上行, 第二驱动件 433退回至冲模机构上方, 等待下一次封膜循环动作。 在焊接膜片 14的同时, 当冲膜机构 42的冲裁刀向上冲裁出膜 片 14后, 冲裁刀向下动作, 膜带 411在送膜主动滚筒 461和送膜从动滚筒 462的作用下 走定长; 已冲裁后的废边膜带 411则在膜张紧滚筒 48的重力作用下, 逐步下行。 当多次 冲裁后, 膜张紧滚筒 48下降到预定的最低位置时, 收膜卷筒 471动作收卷废膜, 使膜张 紧滚筒 48上行; 当膜张紧滚筒 48移动到预定的最高位置时, 收膜卷筒 471停止动作。 如 此往复运动。
实施例 2:
如图 4所示, 本实施例的结构与实施例 1基本一致, 不同之处在于: 送膜机构 46包 括可压紧或松开膜带 411的两个压膜构件 463、 以及用来带动其中一个压膜构件 463沿膜 带 411输送方向往复移动的送膜驱动件 464。下面以靠近冲膜机构 42的压膜构件 463为前 压膜构件, 靠近膜卷 41的压膜构件 463为后压膜构件来进行说明。 当冲膜机构 42的冲裁 刀向上冲裁出膜片 14后, 冲裁刀向下动作; 然后前压膜构件压紧膜带 411, 同时后压膜构 件松开膜带 411, 在送膜驱动件 464的作用下, 前压膜构件向前移动, 将膜带 411向前送 出; 当到达设定供送长度后, 后压膜构件压紧膜带 411, 前压膜构件松开膜带 411, 送膜 驱动件 464带着前压膜构件退回, 完成一次送膜周期。 其余工作过程与实施例 1一致。
实施例 3:
如图 5所示, 本实施例的结构与实施例 1基本一致, 不同之处在于: 输膜组件包括用 于将膜卷 41上的膜带 411拉出的拉膜机构 49, 膜卷 41、 冲膜机构 42和拉膜机构 49沿着 膜带 411输送方向依次布置。通过拉膜机构 49直接从膜卷 41上拉膜实现膜带 411的输送, 拉膜机构 49每次拉出膜带 411的长度即为膜带 411的每次进给长度。
本实施例中, 拉膜机构 49包括带旋转动力的拉膜卷筒 493、 以及用来对拉膜长度进行 测量的编码器 494。 通过拉膜卷筒 493的旋转动力, 将膜带 411从膜卷 41上拉出, 并卷绕 到拉膜卷筒 493上, 可同时实现膜带 411的输送与回收。 其拉膜长度由设于膜卷 41附近 的编码器 494进行控制, 拉膜卷筒 493旋转时, 编码器 494对拉膜长度进行测量; 当到达 设定长度值后, 拉膜卷筒 493停止工作, 完成一次膜带 411的进给。
实施例 4:
如图 6所示, 本实施例的结构与实施例 3基本一致, 不同之处在于: 拉膜机构 49包 括压紧于膜带 411两侧的拉膜主动滚筒 491和拉膜从动滚筒 492,其中,拉膜主动滚筒 491 带旋转动力, 通过拉膜主动滚筒 491和拉膜从动滚筒 492与膜带 411之间的摩擦力将膜带 411拉出。 膜带 411在拉膜主动滚筒 491和拉膜从动滚筒 492的作用下走定长, 已冲裁后 的废边膜带 411直接排入废料箱 6内。
以上仅是本发明的优选实施方式, 本发明的保护范围并不仅局限于上述实施例, 凡属 于本发明思路下的技术方案均属于本发明的保护范围。 应当指出, 对于本技术领域的普通 技术人员来说,在不脱离本发明原理前提下的若干改进和润饰,应视为本发明的保护范围。
