Description
本发明涉及表面特种印刷设备技术领域，尤其是一种全自动丝网冷烫印机。

铝箔存储器f，主要用于存放电化铝箔料卷并在相应机构的配合下输出电化铝箔B，其装设于传送带机构c的上方并位于前端固化器e的出料侧；
铝箔回收器g，主要用于对由铝箔存储器f输出的电化铝箔B进行牵引(即进给速度的控制)并对电化铝箔B的废膜进行回收，其装设于传送带机构c的出料端的上方；
冷烫胶辊机构h，主要使电化铝箔B与承印物A接触并产生一定的承压力，以将电化铝箔B转印至印有胶水的承印物A的图案表面，其装设于传送带机构c的上方并位于铝箔存储器f的出料侧；
后端固化器k，主要用于对位于电化铝箔B与承印物A之间的胶水(即烫印后的胶水)进行二次固化处理(即完全固化处理)，其装设于传送带机构c的上方并位于冷烫胶辊机构h的出料侧；
以及
真空吸气机构m，主要用于将承印物A吸附在传送带机构c上，以防止承印物A在输送过程中存在偏位、变形或者表面不平整等问题，其装设于传送带机构c的下方；
同时，前端固化器e、铝箔存储器f、冷烫胶辊机构h、后端固化器k和铝箔回收器g均位于密封箱b内。
如此，通过设置的密封箱b不但可以在机器上形成一个相对密闭的印刷环境，防止外部环境的污染，而且通过新风口3和排风口4可根据需要对密封箱b内印制品进行风冷处理，从而能够有效防止因前端固化器e和后端固化器k的温度过高而容易引起承印物或者最终的印制品出现变形的问题；而通过真空吸气机构m的负压作用，可将承印物或者成品的吸附在传送带机构c上，从而能够有效防止其在输送的过程中出现偏位或者变形的问题；同时，整个机器中的部件均可通过电气控制总成实现集中控制，为机器的数字化自动控制、运作的平稳性以及作业精度等等提供了硬件基础；另外，整个机器可与其他印刷设备进行无缝接驳，从而针对片材、胶片、纸张等印刷产品，可实现在线流水式一次印刷成型，无需进行额外工序的设置，有效地提高了生产效率。
为有效节省原材料的使用量，最大限度地降低材料的浪费，同时可将多卷安装于不同位置的电化铝箔料卷烫印在承印物A的不同位置，本实施例的铝箔存储器f包括装设于机架体a上并位于传送带机构c的上方的第一料架5、
装设于第一料架5上以用于存放电化铝箔料卷的滑差式气涨轴6、装设于第一料架5上并位于滑差式气涨轴6的下方以用于对由滑差式气涨轴6输出的电化铝箔B进行张力控制的放卷张力器7、装设于机架体a上并位于放卷张力器7的出料侧以用于对电化铝箔B进行纠偏的边缘纠偏器8。
作为其中一个优选方案，在边缘纠偏器8与放卷张力器7之间还设置有若干个第一铝箔导轮9，同时在第一料架5上还装设有一用于对电化铝箔B进行消静电及除尘处理的第一静电除尘器10；从而可在保证铝箔顺利输出的同时，利用第一静电除尘器10对尚未进行贴合的铝箔进行静电消除及除尘等处理。
为使电化铝箔B能够良好的转印至承印物A上，同时最大限度地优化整个烫印部分的结构，本实施例的冷烫胶辊机构k包括装设于机架体a上的第一升降架11、装设于第一升降架11的顶部的升降电机12以及通过升降丝杆组件13吊设于第一升降架11内的烫印胶辊14，如此，当承印物A被输送至烫印胶辊14的下方时，且需要将电化铝箔B转印至对承印物A上时，升降电机12可通过升降丝杆组件13来驱动烫印胶辊14向下移动，从而对电化铝箔B施加一定的下压力，使其与承印物A相接触，并最终将电化铝箔转印至承印物A的图案表面上；而当承印物A的非图案区域出现在烫印胶辊14的下方时，则升降电机12驱动烫印胶辊14相对于传送带机构c向上移动，以此使电化铝箔B与承印物A相分离。
作为一个优选方案，本实施例的铝箔回收器g包括装设于机架体a上的第二料架15、装设于第二料架15的上方以用于对电化铝箔B的废膜进行牵引回收的卷料辊16以及装设于第二料架15下方以用于将电化铝箔B的废膜从承印物A上进行分离的剥离风刀17；同时在第二料架15上还装设有一用于对承印物A(即：经转印处理后的承印物A)进行消静电及除尘处理的第二静电除尘器18，第二静电除尘器18位于剥离风刀17的出料侧。以此，当经过转印处理后的承印物A被输送至剥离风刀17的进料侧时，剥离风刀17恰好位
于电化铝箔B的废膜与承印物A图案表面之间，利用卷料辊16的牵引作用以及剥离风刀17的阻隔作用，可使电化铝箔B的废膜从转印到承印物A的图案表面的电化铝箔B上分离出来，而后再利用第二静电除尘器18对承印物A进行静电消除和除尘处理。
为保证对经转印处理后的承印物A上的胶水进行彻底固化，从而保证烫印的效果，同时增强整个设备的可调节性，本实施例的后端固化器k包括装设于机架体a上的第二升降架19、吊设于第二升降架19内并位于传送带机构c上方的固化器20以及装设于机架体a上并位于传送带机构c下方的升降气缸21；其中，升降气缸21驱动第二升降架19相对于传送带机构c作上下进给运动，以对固化器20的具体位置进行调节，进而实现固化器20与承印物A之间的距离调节；而固化器20则可根据实际情况采用LED UV灯、汞灯或卤素灯。
为最大限度地优化整个机器的结构，提高其布置的灵活性，同时能够使承印物A能够在预设的行程内进行平稳的输送；本实施例的传送带机构c包括沿水平方向由右至左顺序分布的前端传送带22、烫印传送带23和后端传送带24；其中，前端传送带22和后端传送带24均位于密封箱b的外侧，烫印传送带23位于密封箱b内，前端传送带22用于与前端设备C进行接驳，以接收由前端设备C输送而来的承印物A，后端传送带24则用于与后端设备D进行接驳，以输出经过烫印处理后的承印物A；同时，本实施例的真空吸气机构m包括真空泵25、真空储压罐26和若干根吸气管27，真空泵25和真空储压罐26均装设于机架体a内并位于烫印传送带23的下方，真空储压罐26与真空泵25相连，每根吸气管27的尾端均与真空泵25相连，每根吸气管27的头端分别对应地连接于前端传送带22、烫印传送带23和后端传送带24的底面上。如此，可利用真空泵25所产生的动力，在各个传送带的下方均形成负压区，以使承印物A能够被吸附在相应的传送带上，保证承印物A在传送的过程中不出现偏位或者变形的问题。
为增强机器本身占用空间的可调节性，本实施例的前端传送带22的后端轴连于机架体a上，在机架体a内装设有一前端翻转气缸28，前端翻转气缸28的动力轴连接于前端传送带22的底面上；如此可根据需要，利用前端翻转气缸28驱动前端传送带22在密封箱b的外侧相对于机架体a作90度翻转运动(即使前端传送带22向下翻转进行折叠收纳或者向上翻转展开)。同理，本实施例的后端传送带24的前端轴连于机架体a上，在机架体a内装设有一后端翻转气缸29，后端翻转气缸29的动力轴连接于后端传送带24的底面上；利用后端翻转气缸29驱动后端传送带24在密封箱b的外侧相对于机架体a作90度翻转运动。
作为一个优选方案，为简化整个烫印传送带23的结构，同时保证承印物A的转印效果，本实施例的烫印传送带23包括位于前端传送带22与后端传送带23之间的带体30、用于带动带体30进行循环运动的传动轮31以及通过传动带32与传动轮31相连的驱动电机33，传动轮31位于带体30的下方并与冷烫胶辊机构h(具体为烫印胶辊14)相对分布；从而可利用传动轮31与烫印胶辊14构成对辊的结构形式，为承印物A提供一定的支撑力，在烫印胶辊14下移时，能够使电化铝箔B被印制在承印物A上。
基于上述结构，为更加清晰的说明本实施例的冷烫印机的功能效果，如图5和图6所示，本实施例的冷烫印机可采用如下使用及控制原理，即：
1、根据工艺要求在铝箔存储器f上装设电化铝箔料卷并将电化铝箔B按承印物A的输送方向，穿引至铝箔回收器g上；
2、将利用翻转气缸分别将前端传送带22和后端传送带23展开，以分别与前端设备C和后端设备D进行对接，形成流水线；
3、通过电气控制总成根据实际需求来调试并设置好机器的参数，在前端设备C、后端设备D及本机器完成准备工作后，在操作面板1上按下“启动”，本机器即可开始等待前端设备工作；
4、当前端设备C送来的需要进行冷烫的承印物A，到达前端传送带22上时，红外预热器d开始对承印物A上的胶水进行加热流平处理、同时前端固化器e、后端固化器k及真空吸气机构m自动打开，冷烫胶辊机构自动延时下降，铝箔存储器f开始对电化铝箔B进行张力、纠偏处理、铝箔回收器g同时开启并对电化铝箔B进行牵引；
经过红外加热流平→前端固化器e对冷烫胶水半固化→烫印胶辊14将电化铝箔B与承印物A紧压，使电化铝箔B转移到承印物A上→经后端固化器k固化→承印物A与电化铝箔B的废膜剥离→后端传送带24将成品传送带到后端设备D→完成整个过程；
5、工作完成后，按下“停止”按钮，烫印胶辊14自动上升回到原位，相应的器件关闭，前后传送带向下翻转折叠收拢。
以上所述仅为本发明的优选实施例，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本发明的专利保护范围内。
