具体实施方式
下面将结合本实用新型具体实施例中的附图，对本实用新型中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅是本实用新型的一部分实施例，而不是全部实施例。基于本实用新型中的具体实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本实用新型保护的范围。
具体实施例1
请参阅图1-5，本实用新型提供以下技术方案：
一种全自动贴标机用异形面的抚标机构，包括呈镜像对称设置在输送机构100两侧且中心轴线垂直于输送平面的安装轴2，安装轴2的外侧壁上绕其周向并沿径向呈辐射状设置有若干个均匀分布的伸缩杆3。伸缩杆3的一端与安装轴2固定连接，伸缩杆的另一端固定连接有支撑辊4，且该支撑辊的中心轴线与所述安装轴的中心轴线相互平行。若干个支撑辊4的外部共同套设有一抚标带1，该抚标带1与支撑辊4啮合传动，抚标带1上远离输送机构100的一侧设有张紧组件5，张紧组件5与机体固定连接。
本实施例中，安装轴2的外侧壁绕周向设置有若干个均匀分布的伸缩杆3，伸缩杆3的一端与安装轴2固定连接，伸缩杆的另一端固定连接有支撑辊4，若干个支撑辊4的外部套设有抚标带1。通过设置至少由抚标带1、安装轴2、伸缩杆3和支撑辊4组成的抚标机构，其中抚标带1套设在多组支撑辊4的外部形成辊结构，在使用时，可以滚动在包装瓶的外壁，用以抚平标签，当包装 瓶的外壁为凹凸不平的异形面时，则具有伸缩性的伸缩杆3可以根据异形面的凹凸部分进行伸缩，从而使抚标带1能够始终贴合在包装瓶的外壁，从而完成对标签的抚平工作。相对于现有的抚平辊或者抚平板，该抚标机构与异形面的贴合效果更好，因此具有能够贴合异形表面包装瓶从而将标签抚平的特点。
具体的，安装轴2包括轴芯21和同轴活动套设于该轴芯上的轴套22，轴芯21固定连接于机体上，轴套22与轴芯21摩擦转动连接，轴套22套在轴芯21的外部，通过滑动摩擦的方式转动，若干个伸缩杆3的一端均固定安装在轴套22的外侧壁。在使用时，当包装瓶经过贴标机构200将标签贴附后，在输送机构100的带动下，包装瓶流动到抚标机构处，外侧的抚标带1会与包装瓶接触，在摩擦力的带动下使轴套22在轴芯21上转动，使外侧的抚标带1持续挤压包装瓶，将标签抚平。
具体的，伸缩杆3包括同轴设置的杆套31、支撑杆32和弹簧33，支撑杆32固设于轴套22的外侧壁上，杆套31的一端与支撑辊4固定连接，杆套的另一端伸入至支撑杆32内并与支撑杆32滑动连接，弹簧33固定于支撑杆32内，杆套31与支撑杆32通过弹簧33弹性连接。通过设置杆套31、支撑杆32和弹簧33组成的伸缩杆3，使支撑杆32可以在杆套31内弹性的伸缩，支撑杆32在杆套31内具有限位结构，该限位结构的设置与目前的气弹簧伸缩杆结构类似，如在杆套31的端部设置一个直径较小的端盖，支撑杆32上设置一个能滑动在杆套31内的圆盘，形成限位结构，此类结构为本技术领域常规技术方案，本申请中不再赘述，该限位结构可以避免支撑杆32弹出杆套31。在与包装瓶接触时，支撑杆32会跟随支撑辊4对包装瓶表面持续挤压，可以根据包装瓶表面的凹凸情况进行伸缩，从而使外侧的抚标带1始终能够贴合在包装瓶表面。
具体的，抚标带1包括橡胶层11和接触层12，接触层12粘附固定于橡胶层11的外侧壁上，橡胶层11的内侧壁上固设有若干个第一啮齿13，接触层12为无纺布或皮革。支撑辊4的外侧壁上固设有与第一啮齿13配合的第二啮齿 41，第二啮齿41与第一啮齿13啮合传动，橡胶层11与第一啮齿13均为橡胶材料，具有较好的韧性，适用于多次弯曲折叠的情况；无纺布或皮革的接触层12可以对产品表面进行保护，避免造成摩擦损伤，内侧设置的第一啮齿13可以与支撑辊4外壁的第二啮齿41配合，可以避免抚标带1在传动的过程中打滑，让抚标带1与支撑辊4同步运动。抚标带在因为伸缩杆的伸缩运动出现变形的情况下，在凹陷部分可能会出现第一啮齿和第二啮齿的局部脱离，但由于抚标带会受到平提的挤压，且凹陷部分在由于整个啮合部件中的占比较小，整个啮合部分的大部分还是啮合在一起的，这样抚标带反弹回来仍会啮合在一起，不会出现始终脱离的状况。
具体的，张紧组件5包括一弹簧伸缩杆51、一第一转轴52和两个第二转轴53，其中弹簧伸缩杆的中心轴线方向在水平面上垂直于所述安装轴的中心轴线方向，其中第一、二转轴的中心轴线均与所述安装轴的中心轴线平行。弹簧伸缩杆51的一端固定于机体上，弹簧伸缩杆的另一端转动连接(该转动连接方式为通过轴承连接的方式转动连接)有第一转轴52，且该第一转轴能够在弹簧伸缩杆的伸缩带动下沿弹簧伸缩杆中心轴线方向朝所述安装轴方向往复移动，该弹簧伸缩杆的伸缩运动可以通过常规小型气缸等驱动方式进行驱动或者通过弹簧的伸缩量进行调节。两所述第二转轴转动连接(第二转轴53通过轴承连接的方式转动连接在机体上)在机体上且呈对称分布在第一转轴52的两侧，第一转轴52贴合在抚标带1的外壁，两个第二转轴53贴合于抚标带1的内壁，第一转轴52、第二转轴53均与抚标带1转动连接。通过设置张紧组件5，可以在抚标带1在运动过程中，多出或者减少抚标带1的长度能够由弹簧伸缩杆51的伸缩量进行补偿，使抚标带1始终能够与支撑辊4保持紧密的啮合状态，避免松动。
具体的，相邻两个伸缩杆3的夹角为5°～45°，可以根据包装瓶外壁凹凸的曲率程度，来设置伸缩杆3之间的夹角，以使抚标带1能够在伸缩杆3的作用 下，紧贴在包装瓶的外壁上。
具体实施例2
请参阅图6，本具体实施例提供以下技术方案：与实施例1不同的是，伸缩杆3的端部固定连接支撑板4a，支撑板4a为弧形板，且支撑板4a的外侧壁上固设有与抚标带1配合的第二啮齿41，支撑板4a的曲率相对于辊形的支撑辊4更大，适用于包装瓶外壁凹凸变化程度更小的包装瓶。
本实用新型的工作原理及使用流程：当包装瓶经过贴标机构200将标签贴附后，在输送机构100的带动下，流动到抚标机构处，外侧的抚标带1会与包装瓶接触，在摩擦力的带动下使轴套22在轴芯21上转动，使外侧的抚标带1持续挤压包装瓶将标签抚平，通过设置杆套31、支撑杆32和弹簧33组成的伸缩杆3，使支撑杆32可以在杆套31内弹性的伸缩，支撑杆32在杆套31内具有限位结构，可以避免支撑杆32弹出杆套31，在与包装瓶接触时，支撑杆32会跟随支撑辊4对包装瓶表面持续挤压，可以根据包装瓶表面的凹凸情况进行伸缩，从而使外侧的抚标带1始终能够贴合在包装瓶表面。
最后应说明的是：以上所述仅为本实用新型的优选实施例而已，并不用于限制本实用新型，尽管参照前述实施例对本实用新型进行了详细的说明，对于本领域的技术人员来说，其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换。凡在本实用新型的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本实用新型的保护范围之内。
