Description

精炼机及其调距装置 本申请要求于 2012 年 10 月 16 日提交中国专利局、 申请号为 201210396601.X, 发明名称为"精炼机及其调距装置"的中国专利申请的优 先权， 其全部内容通过引用结合在本申请中。 技术领域
本发明涉及橡胶机械技术领域， 更具体地说， 涉及一种调距装置， 本 发明还涉及一种具有上述调距装置的精炼机。
背景技术
精炼机是对再生橡胶进行加工的一种主要设备， 其上设置有多个两两 接触的辊筒， 辊筒表面光滑， 呈腰鼓形， 精炼机在工作时， 其能够使高温 脱硫后的橡胶胶粉进入到两个辊筒之间， 使两个辊筒对其进行高速剪切、 薄通， 进而将橡胶胶粉中的杂质从辊筒的中间部位挤向辊筒的两端， 使杂 质聚集在再生橡胶形成的胶片边缘， 然后用刮刀将胶片边缘的杂质清除， 最终使再生橡胶回复弹性。
在实际的生产过程中， 需要经常调整辊筒之间的间距以适应各种炼胶 工艺的要求， 现有技术中用于调整辊筒间距的调距装置有两种， 一种为手 动调距装置， 在需要调整辊筒的间距时， 操作人员需要人工转动设置在精 炼机机架上的转轮， 通过连接转轮和辊筒轴承座的传动机构来带动辊筒轴 承座的移动， 进而带动设置在辊筒轴承座上的辊筒移动， 以实现调整不同 辊筒间距离的目的， 但是， 由于精炼机上的辊筒体积都较大、 较重， 操作 人员在转动转轮的过程中， 非常的费时费力， 不仅影响工作效率， 还大大 增加了操作人员的工作负担； 另一种调距装置为电动调距装置， 同样由于 需要驱动较大、 较重的辊筒移动， 所以需要大功率的电动机来进行驱动， 这样就使得电动调距装置不仅体积较大， 而且传动结构也较为复杂， 即不 利于精炼机平常的保养维修， 也较大程度的影响了其外形的美观程度。
综上所述， 如何提供一种调距装置， 以实现使其结构更加筒单， 操作 更加方便， 进而提高工作效率， 是目前本领域技术人员亟待解决的问题。 发明内容
有鉴于此， 本发明提供了一种调距装置， 实现了使其结构更加筒单， 操作更加方便， 进而提高工作效率的目的。
为了达到上述目的， 本发明提供如下技术方案：
一种调距装置， 用于调整精炼机不同辊筒之间的间距， 其包括： 设置在精炼机的机架上的液压马达；
与所述液压马达连接以传递所述液压马达输出动力的蜗杆；
与所述蜗杆配合， 且连接所述精炼机的辊筒轴承座的蜗轮。
优选的， 上述调距装置中， 还包括设置在所述蜗轮上且随所述蜗轮旋 转以测量所述辊筒轴承座移动距离的刻度装置。
优选的，上述调距装置中，所述蜗轮与所述辊筒轴承座通过丝杠连接。 优选的， 上述调距装置中， 所述液压马达为两个。
优选的， 上述调距装置中， 所述液压马达的转速均为 300-400r/min。 优选的，上述调距装置中，所述液压马达的扭矩均为 120N/m-180N/m。 基于上述提供的调距装置， 本发明还提供了一种精炼机， 所述精炼机 具有上述任意一项所述的调距装置。
本发明提供的调距装置中， 启动液压马达使其开始工作， 与液压马达 连接的蜗杆在液压马达的带动下旋转以将动力传递给蜗轮， 蜗轮在旋转时 带动与其连接的辊筒轴承座移动， 进而带动设置在辊筒轴承座上的辊筒移 动， 以实现调整不同辊筒之间间距的目的。 本发明提供的调距装置， 与现 有技术中的手动调距装置相比， 无需进行手动操作， 而是由液压驱动， 使 得操作过程更加的筒单， 也提高了工作效率， 与电动调距装置相比， 液压 装置的结构更加的筒单， 无需使用体积较大的大功率电动机以及较为复杂 的传动机构， 也提高了精炼机的美观程度。 附图说明
为了更清楚地说明本发明实施例或现有技术中的技术方案， 下面将对 实施例或现有技术描述中所需要使用的附图作筒单地介绍， 显而易见地， 下面描述中的附图仅仅是本发明的一些实施例， 对于本领域普通技术人员 来讲， 在不付出创造性劳动的前提下， 还可以根据这些附图获得其他的附 图。
图 1为本发明实施例提供的调距装置的结构示意图；
图 2为本发明实施例提供的精炼机的侧视图。
以上图 1-图 2中：
辊筒 1、 机架 2、 液压马达 3、 蜗杆 4、 蜗轮 5、 丝杠 6。
具体实施方式
为了进一步理解本发明， 下面结合实施例对本发明优选实施方式进行 描述，但是应当理解，这些描述只是为了进一步说明本发明的特征和优点， 而不是对本发明权利要求的限制。
本发明提供了一种调距装置， 实现了使其结构更加筒单， 操作更加方 便， 进而提高工作效率的目的。
下面将结合本发明实施例中的附图， 对本发明实施例中的技术方案进 行清楚、 完整地描述， 显然， 所描述的实施例仅仅是本发明一部分实施例， 而不是全部的实施例。 基于本发明中的实施例， 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， 都属于本发明保护的 范围。
如图 1和图 2所示， 本发明实施例提供的调距装置， 用于调整精炼机 不同辊筒 1之间的间距， 其包括：
设置在精炼机的机架 2上的液压马达 3;
与液压马达 3连接以传递液压马达 3输出动力的蜗杆 4;
与蜗杆 4配合， 且连接精炼机的辊筒轴承座的蜗轮 5。 本实施例提供的调距装置中， 启动液压马达 3使其开始工作， 与液压 马达 3连接的蜗杆 4在液压马达 3的带动下旋转以将动力传递给蜗轮 5 , 蜗轮 5在旋转时带动与其连接的辊筒轴承座移动， 进而带动设置在辊筒轴 承座上的辊筒 1移动， 以实现调整不同辊筒 1之间间距的目的。
本实施例提供的调距装置， 与现有技术中的手动调距装置相比， 无需 进行手动操作， 而是由液压驱动， 使得操作过程更加的筒单， 也提高了工 作效率， 与电动调距装置相比， 液压装置的结构更加的筒单， 无需使用体 积较大的大功率电动机以及较为复杂的传动机构， 也提高了精炼机的美观 程度。
为了进一步优化上述技术方案， 本实施例提供的调距装置中， 还包括 设置在蜗轮 5上且随蜗轮 5旋转以测量辊筒轴承座移动距离的刻度装置。 本实施例提供的调距装置的作用就是调整不同辊筒 1之间的相对距离， 在 改变驱动方式的同时， 还设置了刻度装置， 该刻度装置上设置有刻度， 在 蜗轮 5旋转时， 其随蜗轮 5—同旋转， 通过测量蜗轮 5的旋转角度或外边 缘的周向旋转距离来得到精炼机的辊筒轴承座的移动距离， 进而实现对间 距改变量的精确控制， 使得辊筒 1之间的间距能够更加适合不同橡胶的工 艺要求。
优选的， 蜗轮 5与辊筒轴承座通过丝杠 6连接。 为了降低对原有精炼 机的改造程度， 以节省改造成本， 本实施例提供的调距装置中， 采用原精 炼机上的丝杠 6来连接蜗轮 5与辊筒轴承座，进而实现动力的传递，此外， 对于体积、 重量都较大的辊筒 1来说， 采用丝杠 6来进行传动更加适合工 作要求， 是优选方案。 当然， 在不影响本实施例提供的调距装置正常工作 的前提下， 蜗轮 5与辊筒轴 7 座之间还可以通过其他传动部件连接， 例如 齿轮。
具体的， 液压马达 3为两个。 液压马达 3的数量以能够满足工作要求 为准， 即以能够驱动辊筒 1移动为准， 在本实施例中优选为两个。 当然， 在能够满足本实施例提供的调距系统正常工作的前提下， 液压马达 3的数 量也可以为一个或更多个。
进一步的， 上述两个液压马达 3的转速均为 300-400r/min, 扭矩均为 120N/m-180N/m。 本实施例提供的工艺参数为满足工艺要求的最佳参数范 围， 而不是对工艺参数范围的绝对限定， 在满足本实施例提供的调距装置 工作要求的前提下， 调距装置的工艺参数还可以为其他的范围。
基于上述实施例中提供的调距装置， 本发明实施例还提供了一种精炼 机。
由于该精炼机具有上述实施例提供的调距装置， 所以该精炼机由调距 装置带来的有益效果请参考上述实施例中相应的部分， 在此不再赘述。
对所公开的实施例的上述说明， 使本领域专业技术人员能够实现或使 用本发明。 对这些实施例的多种修改对本领域的专业技术人员来说将是显 而易见的， 本文中所定义的一般原理可以在不脱离本发明的精神或范围的 情况下， 在其它实施例中实现。 因此， 本发明将不会被限制于本文所示的 这些实施例， 而是要符合与本文所公开的原理和新颖特点相一致的最宽的 范围。
