对于机械鼓来说，虽然其成本低，机械鼓在滚压轮胎时耗时较长，不利于大规模生产，因此相对于胶囊鼓来说即使成本较低，但应用也非常少。

具体实施方式
需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。下面将参考附图并结合实施例来详细说明本申请。
为了解决相关技术中的轮胎成型时间长，成型效率低的问题，本申请提供了一种轮胎成型方法及机械鼓。
请参考图1至图4，本申请的一种轮胎成型方法，在三角胶贴合结束之前对胎侧进行支撑，以保证后续胎侧滚压时能够在较短的时间内与胎胚很好的进行贴合，从而缩短了整个轮胎成型的时间，同时为了避免两个工序之间产生运动干涉，下述的机械鼓通过对结构进行改进，满足了上述两个工序部分工作同时进行的需求，此外，为了减少反包机构滚压胎侧的时间，提高胎侧的贴合质量和贴合效率，本申请的轮胎成型方法增加了对胎侧预支撑的功能，具体的，在控制贴合机构30滚压三角胶，以将三角胶贴合在轮胎的胎胚上的过程中，同步控制反包机构支撑胎侧，使胎侧朝向轮胎胎胚的侧面聚拢，以使胎侧提前发生一个靠向胎胚侧面的形变，后续再反包机构滚压之后能够使胎侧预胎胚贴合的更紧密，在三角胶贴合完毕后，在控制反包机构滚压轮胎的胎侧，此时，反包机构的压辊组件可以快速的对胎侧进行滚压，胎侧能够与胎胚之间产生一个良好的配合，从而提高了轮胎成型的效率。
本申请除了采用反包机构对胎侧进行反包作业之外，在三角胶贴合完毕后，还控制贴合机构30移动以滚压胎侧，以将胎侧贴合在胎胚上，具体操作时，使贴合机构和反包机构分别对胎侧进行滚压，可以是贴合机构和反包机构在不同时间段内均对整个胎侧进行滚压，提高胎侧贴合质量。
为了实现贴合机构30能够同时对轮胎两侧的胎侧同时滚压的目的，贴合机构30对称地设置两个悬拉臂，悬拉臂上设有反包压辊，两个反包压辊同步运动，能够同时靠近主轴组件或远离主轴组件10；此外，两个悬拉臂还能够实现同时相互靠近或远离地移动，当贴合机构30对轮胎的侧面进行滚压时，两个悬拉臂相互靠近将胎侧压紧在胎胚的侧面，以分别同时对轮胎两侧的胎侧进行滚压。
为了避免反包机构和贴合机构在滚压胎侧时产生运动干涉，本申请的一种实施例采用先控制反包机构滚压胎侧，待反包机构滚压结束后，在控制贴合机构30滚压胎侧的实施方式。具体的，本申请的机械鼓上还设有检测组件，检测组件包括对称设置的两个检测开关，检测开关用于检测第一反包结构的位置，当第一反包结构沿轮胎的径向方向回落到初始位置时，检测开关检测到信号，此时主轴组件高速旋转以将胎侧甩起，贴合机构的两个悬拉臂相互靠近到胎体侧面的最内侧位置并对胎侧进行二次反包。
为了提高反包机构滚压胎侧的贴合质量，本申请控制反包机构采用两步走的方式对胎侧进行滚压，具体的，在反包机构滚压胎侧时，首先使反包机构的第一反包结构20先沿轮胎的径向方向由内向外移动以滚压胎侧，之后第一反包结构20在沿轮胎的径向方向由外向内移动以滚压胎侧，通过最优的路径实现了两侧滚压。
为了避免贴合机构和反包机构之间的运动干涉，本申请的机械鼓将贴合机构设置在主轴组件的外侧，反包机构位于主轴组件上，反包作业时，第一反包结构20沿轮胎的径向方向由外向内移动，第一反包结构运动结束后驱动贴合机构30沿轮胎的径向方向由外向内对胎侧进行滚压，实现一前一后滚压。
通过第一反包结构20内的第一驱动组件211驱动第一反包结构20内的压辊组件201沿轮胎的径向方向移动，压辊组件与胎侧滚动接触，有效减少摩擦，减小对胎侧的损坏。
通过第一反包结构20内的第二驱动组件221驱动第一反包结构20内的压辊组件201压紧胎侧，以使压辊组件201在沿轮胎的径向方向移动的同时始终与胎侧抵接。
为了配合上述方法的实施，本申请还给出了一种具体的机械鼓结构设置来实现上述的轮胎成型方法，机械鼓包括主轴组件10、反包机构和贴合机构30，主轴组件10可转动地设置，以带动轮胎转动；主轴组件采用空心的轴，能够带动反包机构和轮胎的胎胚转动，反包机构 设置在主轴组件10上，以将轮胎的胎侧滚压贴合在轮胎胎胚的侧面；贴合机构30可移动地设置在主轴组件10的一侧，以将三角胶和/或胎侧贴合在轮胎的胎胚上。
请参考图1至图2，本申请的反包机构设置在主轴组件10上，主要用于对安装胎圈后的胎胚进行反包作业，以使胎侧50与胎胚的侧面贴合，通过采用机械鼓的形式替代了胶囊反包，且通过改进机械鼓反包的结构使得反包机构稳定性更好，能够高质量的将胎侧50贴合在胎胚上，且大大缩短了轮胎反包的时间，提高了生产效率，具体设置如下：
本申请的反包机构包括多个第一反包结构20，多个第一反包结构20环绕主轴组件的周向设置，第一反包结构20包括压辊组件201、第一驱动杆组件、第一驱动组件211、支撑组件25和胶囊，压辊组件201用于滚压轮胎的胎侧50；压辊组件201用于与胎侧50直接抵接来滚压轮胎的胎侧50，从而将胎侧50压紧在胎胚上；第一驱动杆组件21与压辊组件201驱动连接，第一驱动组件211与第一驱动杆组件21连接，以通过驱动第一驱动杆组件21摆动使压辊组件201沿轮胎的径向方向移动。第二驱动杆组件22和第二驱动组件221，第二驱动杆组件22与第一驱动杆组件21转动连接，第二驱动组件221与第二驱动杆组件22驱动连接，以通过第一驱动杆组件21驱动压辊组件201压紧轮胎。
为了缩短压辊组件201滚压胎侧50的时间，支撑组件25与第一驱动杆组件连接，以支撑反包机构外侧的胎侧50；支撑组件25在升起后垂直于轮胎的胎侧50或远离轮胎的一端成向轮胎外侧倾斜的角度，胶囊设置在支撑组件25上，以在充气状态下朝向反包机构的外侧鼓起并支撑胎侧50，通过对胎侧50在滚压前的预支撑，不仅节约了后续压辊组件201的滚压时间，同时还可有效避免压辊组件201上的滚轮压到的胎侧50粘到胎胚上。
第一驱动杆组件包括第四驱动杆24、第一驱动杆和第三驱动杆23，第四驱动杆24的一端与第一驱动组件211连接；第一驱动杆与第四驱动杆24的另一端转动连接；第三驱动杆23的一端与支撑组件25远离压辊组件201的一端转动连接，第三驱动杆23的另一端还与第四驱动杆24转动连接，其中，第四驱动杆24、第一驱动杆支撑组件25和第三驱动杆23顺次连接形成四连杆机构。
第二驱动杆组件22与第一驱动杆组件的连接形式有多种，包括：第二驱动杆组件22与第一驱动杆转动连接或者第二驱动杆组件22与第三驱动杆23转动连接。
此外，本申请的机械鼓还包括锁圈结构40，锁圈结构40为两个，对称地设置在主轴组件上，并位于两个反包机构之间，用来锁住轮胎的胎圈，从而对轮胎胎胚进行固定。
