Description

平板打印机
本发明涉及一种平板打印机，尤其是一种使用大致成平板状的打印模板作为打印介质的打印机。本发明基于申请日为2012年09月27日、申请号为201210370335.3的中国发明专利申请，该申请的内容作为与本发明密切相关的参考文献引入本文。
现有的普通打印机通常只能打印纸张，对于金属、木材等板型介质的打印则无能为力。因此现有对板型介质的打印通常是通过热转印来实现的。然而，热转印对墨水的品质要求较高，热转印的工序也较为复杂，成本比较高，因此热转印的普及度不高。
但是，随着社会不断发展，个性化的打印需求逐渐增多，手机壳、T恤等个性化打印市场不断壮大，平板打印机也应运而生。
现有一种将普通打印机改装成平板打印机的技术，其改装方法包括将打印机壳体与打印模组分拆，将打印模组进一步分拆成底座、机芯及转动主轴；将底座上的清洗单元分离开；提供一个平台，将底座剩余部分及清洗单元分别安装至该平台上，清洗单元底部增设垫块，垫块的高度与预设的打印模板的厚度一致，将转动主轴安装在底座剩余部分上并固定，将机芯安装在底座剩余部分上，在机芯与底座剩余部分之间增设有垫块，该垫块高度与预设的打印模板的厚度一致；在底座剩余部分沿打印模板进给方向的前部增加第一打印模板托架，在基座沿打印模板进给方向的后部增加第二打印模板托架。这种改装的平板打印机保留了打印介质进给系统中的动力驱动部分，因此进给精度很高，打印品质良好。
然而，上述改装而成的平板打印机的打印模板从进给方向的上游插入打印机打印区域后，打印模板的起始位置并不固定。若打印模板插入得过深，打印模板与平板打印机形成粗暴接触，可能对打印模板或平板打印机造成物理损伤。
本发明的目的是提供一种结构简单、模板定位精确的平板打印机。
为实现上述目的，本发明提供一种平板打印机，包括：底座，转动主轴，所述转动主轴安装在所述底座上；进给通道，用于实现打印模板的打印进给；模板定位装置，所述模板定位装置设置于底座上且在打印模板的进给方向上位于转动主轴的下游，所述模板定位装置被设置成可阻挡或开启所述进给通道。
进一步的方案是本发明的平板打印机中，所述模板定位装置为凸轮，该凸轮由平板打印机所驱动，且在垂直于所述进给通道的平面内旋转。当打印模板插入打印区域时，凸轮的突出部形成阻挡部，阻挡打印模板过度的插入。当平板打印机发出打印信号时，凸轮受平板打印机信号的驱动在垂直于所述进给通道的表面旋转，使凸轮的突出部离开进给通道，从而开启进给通道。使用凸轮作为模板定位装置，其结构简单，成本低廉。
更进一步的方案是本发明的平板打印机中，所述底座还设有从动轴，所述从动轴在打印模板的进给方向上位于转动主轴的上游；所述凸轮上设有支承部，以支承所述打印模板的端部；从所述支承部向所述从动轴所作的切线高于所述转动主轴的最高点。当打印模板插入打印区域时，打印模板的端部可放置在凸轮的支承部上，且此时打印模板的底表面与转动主轴未接触。这样可以避免转动主轴空转时与打印模板摩擦接触而造成对转动主轴或者打印模板底表面的磨损。当打印机发出打印指令后，凸轮受打印机信号的驱动在垂直于所述进给通道的表面旋转，凸轮的突出部离开进给通道，打印模板随之下降，其底表面与转动主轴形成接触，从而实现打印进给。
本发明的平板打印机避免了打印模板与打印机之间由于粗暴接触所造成的物理损伤。

图2是本发明第一实施例平板打印机底座的第一状态图，此时凸轮阻挡进给通道。
图3是图2工作状态的示意图。

图7是本发明第二实施例平板打印机底座的第二状态图，此时凸轮开启进给通道。
图8是本发明第三实施例平板打印机底座的第一状态图，此时阻挡块阻挡进给通道。
图9是本发明第三实施例平板打印机底座的第二状态图，此时阻挡块开启进给通道。
下面结合附图和实施例对本发明进一步说明。
参见图1，平板打印机1内设有打印喷墨系统、驱动系统及电路控制系统等（图1中均未示出）。打印模板12大致成平板状，其可在打印机打印区域的进给通道13中进给，以实现喷墨打印。
参见图2及图3，打印模板12沿A向在进给通道13中进给。平板打印机1包括底座21，底座21上表面设有转动主轴22，该转动主轴22可受平板打印机1的电信号控制而转动。底座21还设有从动轴23，从动轴23在打印模板12的进给方向上位于转动主轴22的上游。底座21内设有凸轮24，凸轮24在打印模板12的进给方向上位于转动主轴22的下游.凸轮24由平板打印机1所驱动，且可在垂直于所述进给通道13的平面内旋转。在第一状态下，凸轮24的突出部249形成阻挡部，其可阻挡打印模板12的过度插入。凸轮24上更进一步设有支承部241，该支承部241可以支承打印模板12的端部。更进一步的，从支承部241向所述从动轴23所作的切线高于所述转动主轴22的最高点。当打印模板12插入打印区域时，打印模板12的端部可放置在凸轮的支承部241上，此时打印模板12的底表面与转动主轴22之间存在一定的间隙，这样的设置可以避免转动主轴22空转时与打印模板12摩擦接触而造成对转动主轴22或者打印模板12底表面的磨损。
参见图4及图5，当打印机发出打印的指令后，平板打印机1同时提供信号，驱动凸轮24逆时针旋转90度，凸轮24的突出部249（图中不可见）离开进给通道13，此时进给通道13处于开启状态。在凸轮24的旋转过程中，打印模板12下降并与转动主轴22接触。转动主轴22在平板打印机1的驱动下而旋转，打印模板12随之沿A向在进给通道13中进给，从而实现打印进给。
本发明的模板定位装置并不限于本实施例的结构。例如，参见图6和图7，模板定位装置为凸轮34，该凸轮34在平行于所述进给通道的平面内旋转。再例如，参见图8和图9，模板定位装置为一阻挡块44，该阻挡块44在可在垂直于所述进给通道的方向上作直线运动。
本发明的平板打印机，当打印模板从进给方向的上游插入打印机打印区域后，打印模板的前端部接触到模板定位装置，用户便知晓打印模板已安装至合适的位置。当打印机发出打印指令后，模板定位装置开启进给通道，打印模板由转动主轴所驱动，即可实现打印进给。由于设置了模板定位装置，打印模板在初始插入打印机打印区域的过程中会进入到合适的位置，避免了打印模板与打印机之间由于粗暴接触所造成的物理损伤。
