Description

机械鼓
相关申请的交叉引用
本申请要求于2021年9月18日提交至中国国家知识产权局、申请号为202111101158.4，发明名称为“机械鼓”的专利申请的优先权。
技术领域
本申请涉及轮胎生产设备领域，具体而言，涉及一种机械鼓。
背景技术
全钢机械鼓依靠反包杆对胎侧进行反包，反包后在胎侧部位会留下很深的反包杆滚轮滚压后的痕迹。轮胎硫化后，内部充一定气压，在轮胎胎侧部位会出现非常明显的高低起伏，行业内称“红太阳”现象。
现有全钢机械鼓，无论是双排杆机械鼓还是单排杆机械鼓，都是通过长反包杆将胎侧一次反包到位。长反包杆反包胎侧时，由于反包杆比较长，开始反包胎侧时反包杆角度较小，造成反包杆对胎侧的轴向压力较大，反包后胎侧压痕非常深，造成硫化后出现“红太阳”现象。
同时，现有全钢胶囊机械鼓，在反包杆滚轮下面有独立的胶囊，反包杆反包胎侧时，胶囊充气，给反包杆提供一个向上的力，可减少反包杆对轮胎子口部位的轴向压力，减轻轮胎胎侧的压痕。但是，反包杆反包速度与胶囊充气速度很难匹配合适，胶囊充气慢会减弱对反包杆向上的推力，弱化减压痕效果，胶囊充气快会引起反包杆压胎侧不实。
因此，现有技术中存在全钢机械鼓使用性能差的问题。
发明内容
本申请的主要目的在于提供了一种机械鼓，以解决现有技术中全钢机械鼓使用性能差的问题。

在本申请的一个优选实施例中，反包组件还包括至少一个第一复位件，第一复位件分别与驱动装置和多个第一反包杆连接。
在本申请的一个优选实施例中，机械鼓还包括多个第二复位件，多个第二复位件分别与多个第二反包杆抵接。

在本申请的一个优选实施例中，相邻的两个第一反包杆之间具有一个第二反包杆，且相邻的两个第二反包杆之间具有一个第一反包杆。

使用本申请中的机械鼓时，由于反包组件具有第一反包杆和第二反包杆，并且第一反包杆的长度小于第二反包杆，所以能够通过驱动装置先驱动多个第一反包杆对轮胎进行反包，并且在第一反包杆完成反包动作后，驱动装置能够驱动多个第二反包杆对轮胎继续进行反包。因此，在本申请中，通过将第一反包杆的长度设置成小于第二反包杆的长度的目的是通过驱动装置先驱动第一反包杆对轮胎的胎侧的下半部分，即轮胎半径上靠近圆心的部分，进行反 包，然后再通过驱动装置驱动第二反包杆对轮胎的胎侧的剩下的部分进行反包，从而实现了两段式反包，进而达到减轻胎侧压痕的目的。因此，本申请中的机械鼓有效地解决了现有技术中全钢机械鼓使用性能差的问题。

为了解决现有技术中全钢机械鼓使用性能差的问题，本申请提供了一种机械鼓。
如图1至图4所示，本申请中的机械鼓，包括主轴组件10以及分别套设在主轴组件10上的锁圈组件20和反包组件30，反包组件30为两个，两个反包组件30对称设置在锁圈组件20的两侧，反包组件30包括第一反包杆31、第二反包杆32和驱动装置33。第一反包杆31为多个，多个第一反包杆31绕主轴组件10的周向间隔设置；第二反包杆32为多个，多个第 二反包杆32绕主轴组件10的周向间隔设置，第一反包杆31和第二反包杆32间隔设置，且第二反包杆32的长度大于第一反包杆31的长度；驱动装置33分别与第一反包杆31和第二反包杆32驱动连接，以使第一反包杆31和第二反包杆32相对主轴组件10运动。
使用本申请中的机械鼓时，由于反包组件30具有第一反包杆31和第二反包杆32，并且第一反包杆31的长度小于第二反包杆32，所以能够通过驱动装置33先驱动多个第一反包杆31对轮胎进行反包，并且在第一反包杆31完成反包动作后，驱动装置33能够驱动多个第二反包杆32对轮胎继续进行反包。因此，在本申请中，通过将第一反包杆31的长度设置成小于第二反包杆32的长度的目的是通过驱动装置33先驱动第一反包杆31对轮胎的胎侧的下半部分，即轮胎半径上靠近圆心的部分，进行反包，然后再通过驱动装置33驱动第二反包杆32对轮胎的胎侧的剩下的部分进行反包，从而实现了两段式反包，进而达到减轻胎侧压痕的目的。因此，本申请中的机械鼓有效地解决了现有技术中全钢机械鼓使用性能差的问题。
需要说明的是，在本申请中第一反包杆31相对第二反包杆32靠近锁圈组件20。通过这样设置，当驱动装置33驱动第一反包杆31进行反包时，能够保证第一反包杆31能够以一个比较大的角度进行反包，也就是说能够增大第一反包杆31与主轴组件10之间的夹角，或者说是减小第一反包杆31与轮胎之间的夹角，从而可以降低第一反包杆31与轮胎的胎侧产生的轴向分力，从而有效地减轻胎侧此段的压痕。
在本申请的一个具体实施例中，锁圈组件20设置在主轴组件10的长度方向的中线上。或者说锁圈组件20到主轴组件10的长度方向的两端的距离是相同的。
如图2至图4所示，第一反包杆31具有第一支撑位置和第一收回位置，当第一反包杆31处于第一支撑位置时，第一反包杆31与主轴组件10之间的夹角大于等于70度且小于等于90度。并且，第二反包杆32具有第二支撑位置和第二收回位置，当第二反包杆32处于第二支撑位置时，第二反包杆32与主轴组件10之间的夹角小于第一反包杆31与主轴组件10之间的夹角。需要说明的是，在本申请的一个具体实施例中，驱动装置33是先驱动第一反包杆31由第一收回位置运动至第一支撑位置后，然后驱动装置33才会驱动第二反包杆32由第二收回位置运动至第二支撑位置，并完成对轮胎的胎侧的反包。
需要说明的是，在图3和图4中，虚线部分为轮胎。
具体地，驱动装置33包括第一驱动组件331和第二驱动组件332，第一驱动组件331分别与多个第一反包杆31驱动连接，第二驱动组件332分别与多个第二反包杆32驱动连接。通过这样设置可以保证多个第一反包杆31或者多个第二反包杆32之间的同步运动，从而保证本申请中的机械鼓的使用性能。
并且，当第一反包杆31处于第一支撑位置、第二反包杆32处于第二支撑位置时，在第一反包杆31需要回复至第一收回位置、第二反包杆32需要回复至第二收回位置时，第二反包杆32需要先于第一反包杆31运动。
需要说明的是，在本申请中第一驱动组件331和第二驱动组件332可以是驱动气缸或者伺服驱动电机。
在本申请的一个具体实施例中，第二驱动组件332的至少一部分能够带动第二反包杆32沿主轴组件10的轴向运动，且第二驱动组件332还能够驱动第二反包杆32绕第二驱动组件332旋转。需要说明的是，在本申请中设置第二驱动组件332的主要目的是通过第二驱动组件332驱动第二反包杆32运动并使得第二反包杆32能够对轮胎的胎侧进行反包。因此，在本实施例中，当第二驱动组件332驱动第二反包杆32沿主轴组件10的周向运动时，第二反包杆32远离第二驱动组件332的一端实际上在与锁圈组件20或者轮胎的胎侧抵接后，便会沿轮胎的径向运动并完成轮胎的胎侧的反包。
因此，在本申请中第二驱动组件332对第二反包杆32的驱动方式，或者说第二反包杆32的运动方式并不限定于上述的实施例，也可以使第二驱动组件332驱动第二反包杆32以其他的形式产生运动，只要能够实现轮胎胎侧的反包即可。
可选地，机械鼓还包括限位板40，限位板40为两个，且两个限位板40与两个反包组件30一一对应，限位板40设置在第二驱动组件332远离锁圈组件20的一侧，当第二反包杆32处于第二收回位置时，第二反包杆32与限位板40抵接。通过这样设置，能够通过限位板40对第二反包杆32的运动方向或者旋转反向进行限位，从而保证第二反包杆32沿预设的方向运动。
可选地，反包组件30还包括至少一个第一复位件50，第一复位件50分别与驱动装置33和多个第一反包杆31连接。
在本申请的一个具体实施例中，反包组件30还包括多个第一复位件50，多个第一复位件50与多个第一反包杆31一一对应，且第一复位件50的两端分别与第一反包杆31和驱动装置33抵接。在本实施例中，当第一反包杆31由第一收回位置运动至第一支撑位置时，第一复位件50被挤压，而在第一反包杆31由第一支撑位置回复至第一收回位置的过程中，第一复位件50能够为第一反包杆31提供复位力。
在本申请的另一个具体实施例中，反包组件30包括一个第一复位件50，并且这个第一复位件50分别与不同的第一反包杆31连接，同时与驱动装置33连接。
可选地，机械鼓还包括多个第二复位件60，多个第二复位件60分别与多个第二反包杆32抵接。
具体地，第二反包杆32上设置有多个容置槽，多个容置槽分别与多个第二复位件60一一对应，第二复位件60是橡胶圈，且每个第二复位件60分别套设在每个第二反包杆32对应的容置槽内。在本申请的一个具体实施例中，每个第二反包杆32上均设置有三个容置槽，并且橡胶圈为三个。由于在本申请中多个第二反包杆32是沿主轴组件10的周向设置的是，所以每个橡胶圈能够套设在所有的第二反包杆32上，并且，在第二反包杆32由第二收回位置运动至第二支撑位置时，橡胶圈被撑起，并且周长变大，因此，当第二驱动组件332不再对 第二反包杆32产生作用时，第二反包杆32能够在橡胶圈的弹力作用下由第二支撑位置运动至第二收回位置。
可选地，相邻的两个第一反包杆31之间具有一个第二反包杆32，且相邻的两个第二反包杆32之间具有一个第一反包杆31。也就是说，在本申请中多个第一反包杆31和多个第二反包杆32是交错设置的，通过这样设置可以有效地保证轮胎胎侧受力更加稳定，从而保证机械鼓的反包效果。
从以上的描述中，可以看出，本申请上述的实施例实现了如下技术效果：
1、通过设置长度不同的两种反包杆实现了两段式反包；
2、结构简单，性能稳定。
需要说明的是，本申请的说明书和权利要求书及上述附图中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便这里描述的本申请的实施方式能够以除了在这里图示或描述的那些以外的顺序实施。
以上所述仅为本申请的优选实施例而已，并不用于限制本申请，对于本领域的技术人员来说，本申请可以有各种更改和变化。凡在本申请的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本申请的保护范围之内。
