参照图1，本发明公开了一种轮胎硫化设备，包括模具组件1、设置在模具组件1内侧的环座总成2、支撑环座总成2的缸筒组件、驱动件以及传动组件，环座总成2上设有气体循环风扇21，驱动件通过传动组件带动气体循环风扇21转动，缸筒组件包括缸筒本体3和设置在缸筒本体3上的传动箱31。
参照图1和图2，模具组件1为两半模具，也可以为两半活络模具、上开式活络模具、下开式活络模具。具体的，模具组件1包括上模具11和下模具12，模具组件1内侧还设有用于对轮胎成型的硫化胶囊13，环座总成2位于硫化胶囊13内部，环座总成2上设有加热介质进出口22，加热介质优选为氮气。在环座总成2上设有加热器23和气体循环风扇21，加热器23可以是电加热管、感应加热器、红外加热器、换热器等，加热器23对加热介质进行加热，气体循环风扇21驱动加热介质的流动，保证热量高效传递至硫化胶囊13内，且使得硫化胶囊13内的温度均匀，以便于轮胎的成型。气体循环风扇可以为叶轮、轴流风扇等。
参照图1和图2，轮胎硫化设备还包括中心杆4，中心杆4穿设于环座总成2。模具组件1还包括上夹盘14、上压环15、下夹盘16以及下钢圈17，其中，上夹盘14和上压环15夹住硫化胶囊13的上缘，下夹盘16和下钢圈17夹住硫化胶囊13的下缘。下夹盘16固定在环座总成2上，更为具体的，环座总成2包括环座24，下夹盘16通过螺纹连接在环座24上，且两者之间通过密封件进行密封，密封件可以为密封圈。中心杆4的顶端穿设上夹盘14上，并与上夹盘14固定连接，连接方式可以为螺栓连接，中心杆4的顶端与上夹盘14之间通过密封件进行密封，密封件可以为密封圈。模具组件1内部、硫化胶囊13、环座总成2、缸筒组件之间构成密封系统，将驱动件设置在密封系统外部，以减少密封系统内高温高压的环境对驱动件的损坏。
参照图1和图2，环座24与缸筒本体3之间可以设置为一体式结构，当然，也可以通过螺栓固定在一起，两者之间同样可以通过密封件密封，密封件可以为密封圈。
传动箱31与缸筒本体3之间可以设置为一体式结构，当然，也可以通过螺栓固定在一起，两者之间通过密封件密封，密封件可以为密封圈。参照图1和图2，驱动件为驱动电机5，当然，也可以为燃机，本方案优选为驱动电机5。驱动电机5带动转轴32转动，进而带动气体循环风扇21。密封系统包括密封罩6，密封罩6的材质可以是 哈氏合金、钛合金等，密封罩6可起到密封、导磁和减小磁场涡流的作用。密封罩6设置在环座总成2上并位于气体循环风扇21和转轴32之间，气体循环风扇21可相对密封罩6无阻碍旋转，转轴32通过磁性件带动气体循环风扇21。其中，密封罩6与中心杆之间设有第一密封件63，密封罩6与环座之间设有第二密封件64，第一密封件63和第二密封件64均为密封圈。
参照图2和图3，具体的，磁性件包括第一磁性体61和第二磁性体62，第一磁性体61设置在气体循环风扇21的底部，第二磁性体62设置在转轴32的顶端，第一磁性体61和第二磁性体62均为磁铁，进一步的，为永磁磁铁，第一磁性体61与第二磁性体62的磁极相反。进一步的，转轴32的顶端设有环形凸沿321，第二磁性体62设置在环形凸沿321上，第一磁性体61和第二磁性体62上下位置对应，即第一磁性体61和第二磁性体62之间沿着转轴32的轴向设置。其中，密封罩6位于转轴32顶端和气体循环风扇21之间，密封罩6套设在中心杆4上，密封罩6与中心杆4之间设置密封圈，密封罩6与环座24之间设置密封圈，以进行密封。
参照图4和图5，在另一种实施方式中，第一磁性体61和第二磁性体62还可以在水平方向的位置对应，即第一磁性体61和第二磁性体62沿转轴32的径向布置。具体的，转轴32的顶端设有容纳凹部322，气体循环风扇21的底端中部设有配合凸部211，密封罩6的形状与容纳凹部322和配合凸部211之间的间隙相适配。安装时，配合凸部211伸入至容纳凹部322内，第一磁性体61设置在配合凸部211的侧壁上，第二磁性体62设置在容纳凹部322的侧壁上。
参照图6和图7，在第一磁性件和第二磁性件沿转轴32的径向布置另一种实施方式中，转轴32的顶端与气体循环风扇21的凹凸配合进行转换，即，转轴32的顶端设置有配合凸部211，气体循环风扇21的底面中部设置有容纳凹部322，密封罩6的形状设置为与配合凸部211和容纳凹部322之间的间隙相适配。安装时，容纳凹部322伸入至配合凸部211内，第一磁性体61设置在容纳凹部322的侧壁上，第二磁性体62设置在配合凸部211的侧壁上。
本发明实施例的实施原理为，轮胎硫化开始时，氮气经过加热介质进出口22充入硫化胶囊13内部，为硫化胶囊13提供内部压力，加热器23加热为硫化胶囊13提供热量。驱动电机5工作，驱动电机5的输出轴带动转轴32旋转，在第一磁性体61与 第二磁性体62吸引下，气体循环风扇21工作，促使硫化胶囊13内部氮气循环，提高温度均匀性。其中，驱动电机5被密封罩6隔离在密封系统外，使驱动电机5在低温无压力的环境中工作，减少了驱动电机5的损伤，以提高驱动电机5的使用寿命。
实施例二
实施例二与实施例一的不同之处在于，第一磁性体61与第二磁性体62设置的位置不同。参照图8和图9，传动组件包括第一传动件和第二传动件，第一传动件为第一轴体311，第二传动件为第二轴体51。轮胎硫化设备还包括传动箱31，传动箱31设置在缸筒本体3上，转轴32穿设传动箱31，转轴32为空心轴，套设在中心杆4上，并设置在缸筒本体3内，转轴32的顶端与气体循环风扇21连接并带动其旋转。第一轴体311设置在传动箱31内，第一轴体311与转轴32之间为齿轮啮合，当然，也可以为皮带传动或链轮传动，本方案中优选为齿轮啮合。
传动箱31下端与中心杆4之间可以通过密封件密封，或者，传动箱31下端与中心杆4外侧的固定部件7通过第四密封件66密封，固定部件7可以为油缸缸体，密封件可以为密封圈。
参照图8和图9，驱动电机5固定在传动箱31上，轮胎硫化设备还包括电机罩52，电机罩52的一端与传动箱31连接，电机罩52的另一端与驱动电机5连接，连接方式可以为螺栓连接或焊接。驱动电机5的输出轴上还连接第二轴体51，可以为通过螺钉连接或联轴器连接。密封罩6设置在传动箱31上，将第一轴体311和第二轴体51分隔开，第二轴体51和密封罩6均位于电机罩52内。第一轴体311和第二轴体51的轴心线相同，本方案中通过磁性部件将第一轴体311和第二轴体51连接起来，使得第二轴体51能够带动第一轴体311转动。
具体的，第一磁性体61设置在第一轴体311上，第二磁性体62设置在第二轴体51上，第一轴体311向外凸出，第二轴体51靠近第一轴体311的端部凹陷形成有容纳凹部322，第二磁性体62位于容纳凹部322的侧壁上，将第一轴体311的伸出端罩住，这样，第一磁性体61设置在第二磁性体62相对于第一轴体311的径向上，利用第一磁性体61对第二磁性体62的吸合，在驱动电机5带动第二轴体51转动时，第二轴体51可以跟随转动，进而将运动传递给转轴32，转轴32带动气体循环风扇21转动。密封罩6与传动箱31之间还设有第三密封件65，第三密封件65将密封罩6与传 动箱31之间的间隙进行密封，第三密封件65优选为密封圈。
在另一种实施方式中，参照图8和图10，第一轴体311和第二轴体51之间的凹凸配合还可以互换，即，第一轴体311靠近第二轴体51的端部设有容纳凹部322，第二轴体51靠近第一轴体311的端部设有配合凸部211，在第一轴体311和第二轴体51相互配合时，配合凸部211位于容纳凹部322内。其中，第一磁性体61设置在容纳凹部322的侧壁上，第二磁性体62设置在配合凸部211的侧壁上，第一磁性体61和第二磁性体62在第一轴体311的径向上并排设置。
本发明实施例的实施原理为，轮胎硫化开始时，氮气经过加热介质进出口22充入硫化胶囊13内部，为硫化胶囊13提供内部压力，加热器23加热为硫化胶囊13提供热量。驱动电机5工作，驱动电机5的输出轴带动第二轴体51旋转，在第一磁性体61与第二磁性体62吸引下，第二轴体51通过带动第一轴体311旋转，第一轴体311通过齿轮的啮合带动转轴32，使得转轴32也一起转动，转轴32再驱动气体循环风扇21工作，促使硫化胶囊13内部氮气循环，提高温度均匀性。其中，驱动电机5被密封罩6隔离在密封系统外，减少了驱动电机5的损伤。
在另一种实施例中，第一磁性体61与第二磁性体62设置的位置不同，参照图11，具体的，第一轴体311和第二轴体51同轴设置，密封罩6将第一轴体311和第二轴体51分隔，第一磁性体61设置在第一轴体311靠近第二轴体51的端部，第二磁性体62设置在第二轴体51靠近第一轴体311的端部。此时，第一轴体311和第二轴体51轴向正对。第二轴体51旋转时，通过第一磁性体61与第二磁性体62之间的磁力吸引，从而带动第一轴体311转动。
显然，上述实施例仅仅是为清楚地说明所作的举例，而并非对实施方式的限定。对于所属领域的普通技术人员来说，在上述说明的基础上还可以做出其它不同形式的变化或变动。这里无需也无法对所有的实施方式予以穷举。而由此所引伸出的显而易见的变化或变动仍处于本发明创造的保护范围之中。
