具体实施方式
为了使本发明的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本发明进行进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
作为本发明所述便携式多功能验钞机的实施例一，如图1和图2所示，包括机架2、捻钞组件、出钞组件、接钞组件、显示器6、驱动组件和控制电路板，所述机架2内部还设有摄像头和LED补光灯(均未示出)，所述控制电路板上还包括图像对比识别模块，所述图像对比识别模块用于根据摄像头拍摄到的纸钞进行币种和真假钞辨别。
所述便携式多功能验钞机在机架2内部增设了摄像头和LED补光灯，所述控制电路板上还包括图像对比识别模块，在验钞时，摄像头工作对经过的每张纸钞进行拍照，然后由图像对比识别模块进行币种和真假钞辨别，还可以读取纸钞的编号信息，增加了一种检测手段，进一步提高了检测结果的准确性。由于摄像头是安装在机架内部的，所以需要LED补光灯进行补光，以拍到清晰的纸钞图像。
在本实施例中，所述验钞机的出钞口处还设有防尘罩5，所述防尘罩5枢接在机架2上， 防尘罩5可以上下翻转，使用验钞机时，防尘罩5就翻到上面，露出出钞口，不使用验钞机时，防尘罩5就翻到下面，遮盖出钞口，起到防尘作用。
在本实施例中，所述防尘罩5下端还向外延伸有硬币计量盒51，硬币计量盒51上设有刻度，可以用于计量硬币，还可以用于整理硬币，先把包装纸放在硬币计量盒上，然后放入硬币，然后进行成卷包装，非常方便。防尘罩5优选采用透明塑料材料制作。
现有的点钞机的捻钞机构包括本体、设置于本体上的捻钞轴和设置于捻钞轴上的捻钞轮，纸钞放入捻钞轮与本体之间，由捻钞轴带动捻钞轮转动，通过捻钞轮与纸钞之间的摩擦力将纸钞送入走币通道，但由于捻钞轮的外圆周表面全部为橡胶面，在该捻钞机构工作时，纸钞即被捻钞轮连续地送入走币通道，易出现跟币、叠币等现象，故在捻钞轴后侧还设置有拖动纸钞以将纸钞带出走币通道的过钞轴，过钞轴上的送钞轮转动的线速度大于捻钞轮的线速度，使得叠币的纸钞可被分开，但这易导致纸钞被拉断，并且纸钞之间连续的跟币较多，易出现后续的计数等错误。
为了解决这个问题，中国专利文献“200510094210.2点钞机的捻钞机构”公开了一种只有部分橡胶面的捻钞轮，捻钞时可以将纸钞分开送走币通道内，这样就使得纸钞间隔一段距离地进入走币通道，从而将前后进入走币通道的纸钞分开，以便于拖币皮带将纸钞平稳地带出，即可避免出现跟币、叠币现象，又可防止纸钞被拉断。捻钞橡胶块安装在捻钞轮上，事实上在直径不足2cm的捻钞轮上设置安装捻钞橡胶块是较为困难的事情，捻钞橡胶块是软质材料，体积又小，固定困难，反复受压变形，容易脱落，而且捻钞橡胶块的工作表面面积较小，容易磨损，磨损之后，捻钞轮需要全部更换，成本较高，有待改进。
作为本发明所述便携式多功能验钞机的实施例二，如图3至图5所示，本实施例中所述捻钞组件1包括捻钞轴11、捻钞轮12、捻钞胶圈13和捻钞板14，所述捻钞轮12套设在捻钞轴11上，捻钞胶圈13套设在捻钞轮12上，所述捻钞胶圈13上设有一圈完整的防滑纹131，所述捻钞轮12与捻钞胶圈13相配合处的轴向截面为D形。
所述捻钞胶圈13具有弹性，把捻钞胶圈13套设到捻钞轮12上是比较容易的，由于所述捻钞轮12与捻钞胶圈13相配合处的轴向截面为D形，所以捻钞胶圈13在安装后整体也为D形，在捻钞工作过程中，捻钞胶圈13大约只有一半的表面能与纸钞接触，可以达到间隔送钞的效果，避免出现跟币、叠币现象；又由于捻钞胶圈13上的防滑纹131设有一圈完整的防滑纹，所以把捻钞胶圈13套设到捻钞轮12上之后，不必对齐等操作，更方便。如果防滑纹131长时间使用磨损，那么可以手动旋转捻钞胶圈13使其它未磨损的表面处于工作位置，就可以了，相比现有技术使用寿命得以延长两至三倍，完全磨损后，直接替换捻钞胶圈13就可以了，操作容易，维护成本较低。
在本实施例中，所述防滑纹131为棘齿型，摩擦力大，而且与纸钞接触为超柔性接触，弹性空间大，可以接受的磨损量大，或者说磨损量较大之后，仍然能保证不错的工作效果，所以使用寿命长。
在本实施例中，所述捻钞轮12为金属轮或者POM塑料轮。
在本实施例中，所述捻钞轮12外圆周面设有一圈环形凹槽121，所述捻钞胶圈13嵌入所述环形凹槽121内，部分捻钞胶圈13的表面超出捻钞轮12的外圆周面，部分捻钞胶圈13的表面未超出捻钞轮12的外圆周面，所述捻钞胶圈13和环形凹槽121之间形成的摩擦力较大，捻钞轮12和捻钞胶圈13在工作过程中，位置稳定性高，不会移位。
作为所述捻钞组件的另一实施例，如图6所示，所述捻钞轮12外圆周面设有一圈环形凹槽121，所述捻钞胶圈13的内表面上设有环形凸起132，所述环形凸起132嵌入所述环形凹槽121内，所述环形凹槽121和环形凸起132之间形成的摩擦力较大，该结构也能增加捻钞轮12和捻钞胶圈13之间的摩擦力，有效防止两者相对移位。
作为本发明所述便携式多功能验钞机的实施例三，如图7至图8所示，与实施例二不同之处在于所述验钞机还包括压钞件4，所述机架2包括左右侧板21、22，所述左右侧板21、22均设有固定轴3，所述固定轴3设置在捻钞轴11旁边，所述压钞件4套设在固定轴3上，所述压钞件4与捻钞板14之间最近的距离为3-5mm。纸钞被捻钞轮12带起从捻钞轮12和捻钞板14之间穿过，由于纸钞具有较大的速度，而且纸钞的折痕不规则，容易向上飞起，产生飞钞的情况。本实施例所述压钞件4可以压住从捻钞轮12送来纸钞，平稳地离开捻钞轮12和捻钞板14，顺利地进入出钞组件，防止飞钞，使捻钞过程更加平稳。由于纸钞的折痕不规则性，压钞件4不宜直接与捻钞板14接触，有机会卡钞，压钞件4与捻钞板14之间最近的距离设置为3-5mm，是比较合适的，保证纸钞的通过率，又能保证较好的压钞效果，防止飞钞。
在本实施例中，所述压钞件4包括套环41和尾部压条42，所述套环41内表面设有凹槽411，所述固定轴3的外圆面上设有凸起31，所述凸起31位于凹槽411内，使套环41与固定轴3在3-5度的范围内自由旋转，所述尾部压条42的长度大于5cm。由于压钞件4可以绕固定轴在3-5度的范围内自由旋转，所以高速过来的纸钞冲击压钞件4时，压钞件4的重力不足以压制纸钞时，就会向上旋转，增加进钞空间，增加了结构的柔性，此时一般情况是纸钞的折痕太大，纸钞太不平整导致的，增加进钞空间以避免卡钞。但是压钞件4也不能向上旋转角度过大，否则容易与外部其它结构碰撞，产生噪音。另外，还可以在所述凸起31上套设一硅胶套，防止凸起31和凹槽411之间接触磨损，以及降低接触噪音。在允许的范围下，纸钞的引导距离越大越好，为了保证基本的纸钞引导效果，所述尾部压条42的长度应 大于5cm。
作为所述压钞件的另一实施例，如图9所示，所述压钞件4包括套环41和尾部压条42，套环41上设有缺口412，所述固定轴3的外圆面上设有凸起31，所述凸起31位于缺口412内，使套环41与固定轴3在3-5度的范围内自由旋转，所述尾部压条42的长度大于5cm。由于缺口412的存在，所述凸起31可以做的较粗较强壮，高度上也不再受限，可以设计得更高，解决产品的强度问题，降低维护率，提高用户满意度。可以在所述凸起31上套设一硅胶套，防止凸起31和缺口412之间接触磨损，以及降低接触噪音。
以上所述仅为本发明的较佳实施例而已，并不用以限制本发明，凡在本发明的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本发明的保护范围之内。
