Description

内加热塑料挤出机
技术领域
本发明涉及一种内加热塑料挤出机，属于塑料挤出机技术领域。
背景技术
现有技术中，塑料挤出机一般采用机壳外部的加热方式。缺点是内外加热不均匀，挤出效果不好。因此有些塑料挤出机在挤出螺杆内部加入电阻丝、电热管等加热元件，使得塑料挤出机内外加热均匀，但电阻丝、电热管结构复杂，元件容易损坏，造成螺杆内加热温度不稳定，因此需要经常更换，而且电热效率低，成本较高。
发明内容
本发明的目的在于：提供一种内加热塑料挤出机，加热速度快，更加均匀以克服现有技术的不足。
本发明是这样实现的：内加热塑料挤出机，它包括机壳，在机壳外设有加热层，在机壳内设有挤出螺杆，挤出螺杆的一侧连接电机，挤出螺杆的另一侧连接轴承座，挤出螺杆内设有空腔，在空腔内设置导油管，导油管穿出轴承座、机壳的侧壁与加热油箱连接。
前述的内加热塑料挤出机，所述挤出螺杆上设有温度感应器。
前述的内加热塑料挤出机，所述挤出螺杆内设置U型导油管。
前述的内加热塑料挤出机，所述导油管与加热油箱的连接段设有保温管。
本发明的导油管能够装入热油，在内加热塑料挤出机内外同时加热，加热均匀，导热油的热效率更高，使用成本更低。同时，导油管的结构简单，同电热管、电热丝相比，不易发生故障，可以长期工作而不用维修。同现有技术相比，本发明具有结构简单，热效率高，加热均匀，维护方便等优点。
附图说明
附图1为本发明的结构示意图。
具体实施方式
本发明的实施例：内加热塑料挤出机，制作挤出机的机壳1，在机壳1外安装加热层4，在机壳1内安装挤出螺杆2，挤出螺杆2的一侧连接电机3，挤出螺杆2的另一侧连接轴承座10，使得挤出螺杆2可以旋转，挤出螺杆2内制作出空腔5，在空腔5内安装导油管7，导油管7穿出轴承座3、机壳1的侧壁与加热油箱8连接。轴承座3中间设置通孔，在机壳1的侧壁通过安装盘11与导油管7连接。挤出螺杆2内采用的是U型导油管7，U型导油管7的两个管口与加热油箱8连接，在挤出机的一端完成导热油的循环。
在挤出螺杆2上安装多个温度感应器6，能够检测挤出螺杆2各段的温度，温控调节更精确。
在导油管7与加热油箱8的连接段还设置保温管9，保温节能。
工作时，将塑料放入内加热塑料挤出机，由加热层4和导油管7同时对塑料进行加热。并根据温度感应器6监测的温度，及时调整导油管7中导热油的温度。
