Description

三螺杆挤条机 技术领域
本发明涉及挤条机领域，具体涉及一种三螺杆挤条机。
背景技术
挤条机是利用特定形状的螺杆，在加热的机筒中旋转，将由料斗中送来的塑料向前挤压，使塑料均匀地塑化(即熔融)，通过机头和不同形状的模具，使塑料挤压成连续性的所需要各种形状的塑料层，挤包在线芯和电缆上。目前市场上挤条机的送料漏斗的都是全开放式的，在生产加工过程中，需要挤压产品，使其通过出料口，但是挤压过程中料斗在向前的挤压力作用下，会向前运动，但是出料口小，导致会让料向上运动，会导致料从上面溢出，造成浪费，还需要人不停地清理维护，浪费大量人力，导致生产成本加大。以往挤条机对螺杆进行清洗，先停止设备运行，然后直接从进料口中对螺杆进行清洗，这种清洗方法，很费力，而且很多地方清洗不到，导致清洗不干净，就继续使用，给设备带来一定的损害，对产品也会参杂。而且目前市场上的挤条机是双螺杆挤条机，工作量小，而且不方便对螺杆清洗维护保养，工作时会导致料从进料口中溢出，浪费材料，工作效率降低。而且螺杆一端固定连接驱动轴，另一端都是悬空的，长时间就会悬空端下沉，另一端轴承磨损严重。

穿入纵向轴孔和齿轮轴的锥形孔内进行销紧。
本发明使用时，把投料斗一侧设计的投料门21打开，把物料从投料斗的一侧的投料门21内投放到混合挤料箱内，启动电机，电机驱动变速箱，变速箱内的齿轮的传动，改变速比，使得两侧的螺杆转速比主螺杆转速快，通过对齿轮的齿牙的改变，对两侧螺杆的转速可以进行设定，在设定好的转速下，两侧螺杆由外向内旋转，即两侧螺杆都把靠边物料上翻起来，通过“八”字状设计的叶片把物料向中间主螺杆压送，这样就能够防止物料卡在边上，同时能够有效的把物料往中间下压，防止物料溢出，主螺杆的螺距和螺深刚开始很大，到达出料口时渐渐变小，这样设计的好处是进料快，主螺杆位于出料口内的螺距和螺深是恒定的，这样就保证挤出条状产品符合要求，本发明悬臂梁的设计给两侧螺杆装加了一个支撑轴承，设计巧妙，解决了螺杆下沉现象，而且本发明方便清洗，只需要把混合挤料箱固定在机架上的螺钉拆除，把主螺杆和两侧螺杆与变速箱连接的锥形销打开，就可以把螺杆和混合挤料箱一并从机架上拆下，两侧螺杆也可以通过悬臂梁端取出清洗，主螺杆需要把出料口拆除取出清洗，清洗方便，而且很容易清洗干净，安装也方便快捷，这样保证设备能够正常工作，保证换料后不会混料现象，同时也延长了设备的使用寿命。
