Description

一种印刷设备及使用该印刷设备的单双面打印方法 技术领域
本申请涉及一种印刷设备及使用该印刷设备的单双面打印方法。
背景技术
印刷设备是用于生产印刷品的机器、设备的总称。现代的印刷设备的发展方向是高速、高效、高质方向发展以及大型、多色、多功能、自动化、联动化、系列化。
CN104924755A公开了一种同步单双面数码喷绘机及其绕布方法，喷绘机包括机架、放布辊、收布辊、两组喷绘小车及主动辊，两组喷绘小车分别在安装于机架上的两组轨道梁上往复运动，两组喷绘小车上均带有打印机构，在两组喷绘小车的下方均设有安装在机架上的喷绘平台；在两个喷绘小车的下方均设有主动辊，两主动辊分别由安装在机架上的两个独立的驱动装置驱动逆向旋转。本发明在每个喷绘平台下方均设置了一个主动辊，两个主动辊分别由独立的驱动装置驱动同步逆向旋转，保证了双面喷绘的步进精度；本发明既可同步双面精确喷绘，又可在一台机器上同时进行两个画布的单面喷绘，实现了一机多用。该申请能够解决在速度或者双面打印之间的择一选择，但基本上是采用的两套单面打印设备进行拼接设置得到的，因此其同步性非常靠控制系统的控制以及操作人员的经验，这使得使用过程中稳定性一般，尤其对于软材的打印来说，很难保证精确性以及打印质量。
CN206049040U公开了一种双面打印机，包括打印小车，所述打印小车上设有送纸电机，且打印小车安装在打印机体的上方，所述打印机体的内部上方设有双面打印头，所述双面打印头一侧与反面走纸胶辊连接，且双面打印头的另一侧与送纸辊连接，所述反面走纸胶辊安装在压辊支架体的上方，所述反面走纸胶辊与灯箱布、软膜连接，且灯箱布、软膜安装在送带轮上，所述送纸辊 与正面走纸胶辊连接，且正面走纸胶辊安装在压辊的上方。本实用新型实现全自动环绕送纸可以自动双面打印，省去了人力来回搬运的程序，机器自动环绕打印，可以进行单面打印和双面打印打印快速效率高，具有印刷质量高，字迹不退色，可长期保存，生成潜像的功耗小，无噪声，简单可靠的优点。该申请实质是单面打印机但是采用一种自动环绕的方式使得能实现双面打印，对于纸张采用该种方式是适宜的，但是对于长度较长的打印底材，该申请并不能进行有效处理。
申请内容
为了解决上述问题，本申请提出了一种印刷设备及使用该印刷设备的单双面打印方法，一方面包括一种印刷设备，包括第二平台和可与第二平台发生相对运动的第一平台，所述第一平台上设有数量不少于两个的打印机构，所述第二平台上设有与所述打印机构分别对应设置的工作台，还包括一设在第二平台上的放料辊，所述放料辊设在所述工作台的下方中部以使得从放料辊引出的打印底物可以在工作台中部分别引入两打印机构下方的工作台上，并在两打印机构下方的工作台上借助设在第二平台上的转向辊进行方向翻转。此处所述到打印机构，是指的在物理上能够独立开来的单元，可以是两个打印装置，也可以是一个大的打印装置，但是在使用时，可以在物理空间上区分使用，而形成不同的打印机构；而打印机构本身可以有一个打印头，也可以有多个打印头，只要可以起到打印作用即可。第一平台可以采用诸如喷车或者滑块或者龙门等形式，通过齿轮齿条、丝杠滑块等传动形式，也可以采用活塞驱动等方式与第二平台相连。对于收料辊，其可以脱离本装置设在外部，也可以设在本装置上，可以是主动辊也可以是被动辊；通过将放料辊设置在工作台的下方，使得在进行双面打印时，可以在一个运动平台，即第一平台的作用下，实现双面打印，这样可以完美的保证两个打印机构的同步性，从而提高正反面打印时的打印效果，较于普通的双打印机构布局到不同的平台(常见的是打印小车等)的方法，减少了一个同步顾虑因素，提高了打印的效果。
优选的，所述工作台包括设在第二平台上的打印平台，所述打印平台与打印机构对应设置，在打印平台的两侧分别设有打印辊。在结构布局上，工作台可以采用两种方式，一个是分体设置的多个打印平台组成一个工作台，或者是一个打印平台，在打印平台上开设有让打印底物穿过的条形通孔；在分体设置时，各个打印平台两侧都设置打印辊；而在整体设置的打印平台上，在打印平台的条形通孔两侧可以通过辊的方式也可以通过其他导向结构的方式实现打印底物的翻转，而在整个打印平台的两侧则设置打印辊来实现打印底物的导入导出。
优选的，所述打印辊和转向辊全部为主动辊。在对于柔性布料进行打印时，必须保证各个辊之间的线速度一致，以使得不会产生积蓄布料的现象，而设置为主动是其一致性的必须条件；当然在有些情况下，需要进行不同步打印时，主动辊也可通过自控调节的方式来实现打印要求。
优选的，还包括烘干器，所述烘干器设在相对于工作台的打印底物出料端。烘干器是为了及时将打印机构出来的油墨烘干。
优选的，所述打印机构以及工作台的数量为两个，所述打印机构与打印平台配合设置。进行双面打印时的通常设置，可以提高整体的可操控性。
优选的，所述两打印平台处于第一平面上，所述打印机构滑动设置在第一平台上，所述打印机构的滑动方向与第一平面基本平行设置。
优选的，至少一打印机构通过打印滑块与第一平台活动相连，所述第一平台上设有一丝杠，所述打印滑块活动设置在丝杠上，所述丝杠与提升电机或者手柄相连。便于将打印机构提升以在初期布置打印底物时，方便打印底物的穿过。
另一方面，包括一种双面印刷方法，包括通过放料、打印然后收料的过程，还包括：
提供一打印底物，所述打印底物用于打印；
提供一打印设备，将所述打印底物缠绕在放料辊上，然后从两工作台之间 穿过后通过其中一个工作台，然后通过转向辊转向翻转后再从两工作台之间穿过后通过另外一个工作台。
优选的，所述打印底物为柔性材料，所述转向辊与打印辊全部为主动辊且设定为一致线速度。
优选的，所述放料辊为被动辊或者放料辊为主动辊、但放料辊与沿打印底物方向与之紧邻的打印辊之间存在张紧力。
另一方面，还包括一种单面双倍印刷方法，包括通过放料、打印然后收料的过程，还包括：
提供一打印底物，所述打印底物用于打印；
提供一打印设备，将所述打印底物缠绕在放料辊上，然后从两工作台的一侧穿过后通过其中一个工作台后再直接通过另外一个工作台。由于单双面打印只是一种使用方法上的不同，对于设备本身结构并不会造成任何的影响，因此使用方法的限定不会对设备结构造成影响。本装置用于打印单面时，其实现基础是打印底物需要打印机构进行往复运动多次才能完成打印的原理，例如，若一个图案需要往复运动10次才能完成打印，则在打印时，可以一个打印机构往复运动5次即可达到整体10次的效果，由于打印部分的速率加快，其整体的速度也会翻倍进行。
本申请能够带来如下有益效果：
1、通过在第一平台上设置多个打印机构，使得打印机构之间的距离是一种物理上的固定距离，因此在打印底物的行进这一方向维度上不会发生由于电脑控制或者校准带来的偏差，影响打印的精度；
2、通过将放料辊内置，使得可借助较少的转向辊以及布置空间即能完成转向，这可以减少打印底物在内部缠绕的长度，减少浪费，并且由于变形的基础距离变短，可以提高打印的一致性；
3、通过将打印平台设在同一平面上，能够保持在两个工作台之间环境的统一，避免发生重合度差的现象；
4、全部为主动辊的设置是为了便于对于柔性材料进行打印，由于柔性材料在进行双面打印或者进行单面倍速打印时，必须保证在两个平台上具有一致的张紧度，否则会导致打印图像不重合或者重合程度达不到设定要求；
5、通过不同的缠绕方式，在需要重复多次打印的情况下，可以实现单倍双面或者双倍单面打印。

可以理解的，打印机构3可以设置成多个，如3个、4个等，只要其下方有打印平台即能完成打印作业。
在第二个实施例中，如图1-2所示，在第一个实施例的基础上，第一平台2，即打印小车，与第二平台1的连接点可以是采用设在第二平台1侧部的方式(如图1所示)，也可以采用连接点设在第二平台1中部的方式(如图2所示)。
可以理解的，所述工作台4包括设在第二平台1上的打印平台，所述打印平台与打印机构对应设置，在打印平台41的两侧分别设有打印辊42。
可以理解的，在此基础上也可以采用其他结构形式，只要可以保证两个打印机构可以同时附着在第一平台2上即可。
可以理解的，在打印柔性材料或者是其他需要设置在不同打印平台41上不一致的应力的情况时，需要将所有的打印辊42和转向辊6全部设置为主动辊。在对于柔性布料进行打印时，必须保证各个辊之间的线速度一致，以使得不会产生积蓄布料的现象，而设置为主动辊是其一致性的必须条件；当然在有些情况下，需要进行特定条件下的不同步或者非相同应力打印时，主动辊通过自控设置也同样可以实现。
可以理解的，可以在打印底物7出料端设置烘干器8，使得能够及时将打印机构3出来的油墨烘干。
可以理解的，所述两打印平台41在工作时处于同一平面，即第一平面上，以提高两打印平台41不论是在所述打印机构3滑动设置在第一平台2上，所述打印机构3的滑动方向与第一平面基本平行设置。
在第三个实施例中，如图2所示，在第一个实施例的基础上，可以将打印机构3活动设置在第一平台2上，打印机构3通过打印滑块9与第一平台2活动相连，所述第一平台2上设有一丝杠10，所述打印滑块9活动设置在丝杠10上，所述丝杠10与提升电机11或者手柄12相连。以使其能够相对于打印平台41做靠近和远离的动作，这样可以便于打印底物7的初始布置并且在某 些特定情况下可以起到调节打印机构3与打印平台41距离的作用，以获得最优的打印效果。
如图2所示，左侧是采用电机电控的方式，当需要调节打印机构3与打印平台41之间的距离时，启动提升电机11，提升电机11带动丝杠10转动，丝杠10带动打印滑块9运动，打印滑块9带动打印机构3运动即完成最终的调节。右侧是采用手柄12调节的方式，当需要调节打印机构3与打印平台41之间的距离时，旋转手柄12，手柄12带动丝杠10转动，丝杠10带动打印滑块9运动，打印滑块9带动打印机构3运动即完成最终的调节。
在第四个实施例中，如图1-2所示，是在不同的结构下进行双面打印的方式，即将打印底物7缠绕在放料辊5上，然后从两工作台4之间穿过后通过其中一个工作台4，然后通过转向辊6转向翻转后再从两工作台4之间穿过后通过另外一个工作台4，当然，在出料端可以利用烘干器8进行烘干作业。
可以理解的，当打印底物7为柔性材料时，所述转向辊6与打印辊42全部为主动辊且设定为一致线速度以保证两打印平台41之间以及不同辊之间的张力一致，以提高打印的精度，避免由于拉伸使得双面打印时的两面的图案产生错位。
可以理解的，所述放料辊5为被动辊或者放料辊5为主动辊、但放料辊5与沿打印底物7方向与之紧邻的打印辊42之间存在张紧力，将张紧力的产生置于进料端，能够保证整个系统中的打印底物7张紧力的稳定性，以保证打印效果。
在第五个实施例中，如图3所示，一种单面双倍印刷方法，将打印底物7缠绕在放料辊5上，然后从两工作台4的一侧穿过后通过其中一个工作台4后再直接通过另外一个工作台4，即能完成单面双倍的打印作业。
本说明书中的各个实施例均采用递进的方式描述，各个实施例之间相同相似的部分互相参见即可，每个实施例重点说明的都是与其他实施例的不同之处。尤其，对于系统实施例而言，由于其基本相似于方法实施例，所以描述的 比较简单，相关之处参见方法实施例的部分说明即可。
以上所述仅为本申请的实施例而已，并不用于限制本申请。对于本领域技术人员来说，本申请可以有各种更改和变化。凡在本申请的精神和原理之内所作的任何修改、等同替换、改进等，均应包含在本申请的权利要求范围之内。
