Description

一种大型橡塑炼胶 ΐ几、 压延机的压辊 技术领域
本发明涉及一种橡塑炼胶机、 压延机的压辊， 特别是大型、 特大型橡塑炼 胶机、 压延机的宽幅压辊。 背景技术
在橡塑行业生产过程中， 特别是在橡塑炼胶机、 压延机的辊筒使用中， 生 产产品最宽宽度是辊筒面工作长度来决定的。 在工作中， 通过辊筒之间的相对 转动， 把胶化橡塑挤压成薄片， 其薄片的宽度大小就决定了产品幅度大小和产 量的多少。 其辊筒一般用冷激铸铁或锻钢或中间球铁外层冷激铸铁制成中空轮 或钻孔轮。 因为材料及制作条件的原因， 辊筒长径比一般在 3.5以下， 其辊面 工作尺寸（直径 X长度）在 f 850mm X 3500mm以下， 这给生产宽幅 3500以上 压延产品设置了障碍。 设计一种辊筒长径比突破 3.5， 辊面工作尺寸大于 # 850mmX 3500mm以上的辊筒来生产宽幅压延产品是本发明的所在。 发明内容
为了克服因辊筒长径比小、 工作面尺寸窄的缺点， 本发明设想技术方案是 改变辊筒的制作工艺结构及材料成份， 来增大辊筒的长径比， 从而得到加大辊 筒工作面的尺寸， 以克服市面上不能生产压延宽幅 3500以上产品的区域。本发 明是通过如下的技术措施来实现技术方案的： 一种大型橡塑炼胶机、 压延机的 压辊， 它包括： 轴承组 1、车壁 2、支架 3、悬挂杆 4、旋转接头 5、压缩弹簧 6、 螺帽 7、辊筒 8、内管 9、塞头 10和堵头 11组成，其特点在于所述的用槽钢（也 可以用角钢） 制成的支架 3固定在轴承组 1和车壁 2上， 圆钢制成的悬挂杆 4 穿过支架 3中间长孔， 下端螺纹连接固定在旋转接头 5上， 上端在穿过支架 3 后外套一（屈强系数 K为 0.1kg/mm-2kg/mm， )压缩弹簧 6， 压缩弹簧 6的上部 螺紋连接相应螺帽 7， 限制并压缩弹簧 6， 以拿在工作中弹簧 6脱落悬挂杆 4， 旋转接头 5被套接固定在辊筒 8的左端； 辊筒 8为冷激铸件、 芯球铁外包冷激 铸件和铬镍合金锻钢其中之一材件制成， 其工作面长度
