立柱骨架可用能够承受重量具有一定刚度和强度的金属部件组装而成框架式结构。所述立柱还包括多块立柱面板,所述立柱面板中至少一部分和立柱骨架可拆装连接。在运输时,有一种方式,这些面板能够从立柱骨架801上拆下而采 用合适的包装,不会在运输时被磕碰损坏,而在使用现场,仅仅简单地依附连接到立柱骨架1上即可完成立柱组装,而无需进行复杂的拼装立柱工作。即便是在运输时面板不拆卸,如果发生磕碰,也仅仅是更换局部的面板,而不会造成整个立柱报废的问题,节省成本。
而对于立柱骨架而言,不易被磕碰损伤外观,即便被磕碰也不易变形,如果缠绕机拆掉面板运输,立柱骨架即便有局部的外观损伤,对立柱外形影响也很小或不会影响立柱外形。
进一步地,立柱骨架801本身是一种单元结构,自身形成一个整体,适于和底座进行铰接连接,这样,立柱的骨架801可以和以往的立柱那样采用转动连接的方式预装在底座100上,既便于运输同时在现场安装时更加方便,立柱骨架的转动连接位可以是在其正面面向转盘200的这一侧底部,通过管状部件811和底座上的横销107铰接。
对于立柱面板来说,可以是全部立柱面板均可拆装地与立柱骨架连接。即便如此,不一定需要将某些不易被磕碰的面板或将会被某些缠绕机部件遮挡的面板在运输时拆掉(这些面板也不一定要可拆装地与立柱骨架连接),比如处在立柱的下部正面面向转盘的面板821在出厂运输时可连接在立柱骨架801上。又比如会被升降膜架900遮挡的面板,也不一定要拆下。
所述可拆装连接可以是螺丝、扣接、卡接、插销接等各种机械连接结构。
所述和立柱骨架可拆装连接的立柱面板中包括了电控门803,电控门上会按照按钮、指示灯等,一般地,在电控门的背面会安装一些电气装置。所述电控门803可以通过销830和立柱骨架转动连接。
所述和立柱骨架可拆装连接的立柱面板包括检修门804,所述检修门804采用倾斜的插槽841和横向插销842配合结构与立柱骨架801可拆装连接,打开和关闭方便,且在检修时没有干涉。
上述的门803、804如果需要设置锁,可以采用常规结构的锁直接锁在立柱骨架801上。
所述立柱的顶盖805和立柱骨架801连接,其连接方式也可采用螺丝连接。
缠绕机的升降膜架900的升降机构806与立柱骨架连接,与以往相比,升降机构更加不易变形和偏离位置、升降工作更加稳定。
附图标号822、823、824、825、826、827、828均为立柱的根据需要而与立柱骨架可拆装连接的面板。
如图19-20所示,对于有四个角呈斜角的立柱外形,对那些作为需要转动打开的门的立柱面板,比如电控门803b,电控门上方和下方的门824b、825b,可以通过合页807和相邻的立柱面板在斜角部位可拆装地连接。在图19、20中附图标号和图16-18相同的,代表相同的含义。
实施例7,参照图21-24。

所述送膜膜架的顶部设置有上部膜架结构,上部膜架结构中设置传动机构,第一滚筒和第二滚筒通过各自的传动机构和各自的驱动电机连接,所述驱动电机固定在上部膜架结构的下方。
第一滚筒901和第二滚筒902的位置更偏向送膜膜架904的正面侧从而留下 背后的空间来布置第一驱动电机910、第二驱动电机920,所述第一驱动电机910、第二驱动电机920的位置处在第一滚筒和第二滚筒的背后,膜卷轴903设置在第一滚筒901进膜这一侧的送膜膜架904上,附图标号930为套膜卷轴903上的膜卷。
