Description
技术领域Technical Field

背景技术Background Art
塑料挤出机是一种常用的设备，用于将熔化的塑料挤出成特定形状的产品。在传统的塑料挤出机中，通常采用螺旋挤出机来实现物料的挤出。螺旋挤出机由螺杆和螺杆筒组成，通过螺杆的旋转运动将塑料熔体推入螺杆筒中，并将其压力增加到所需的挤出压力。然后，熔体通过模具挤出，形成所需的产品，然而现有的塑料挤出机的挤出螺旋顶出装置还存在一定的缺陷有待完善；Plastic extruder is a commonly used equipment used to extrude molten plastic into products of specific shapes. In traditional plastic extruders, a screw extruder is usually used to achieve material extrusion. The screw extruder consists of a screw and a screw barrel. The plastic melt is pushed into the screw barrel through the rotation of the screw and its pressure is increased to the required extrusion pressure. Then, the melt is extruded through the die to form the desired product. However, the extrusion screw ejection device of the existing plastic extruder still has certain defects that need to be improved;
现有技术中的塑料挤出机的挤出螺旋顶出装置在使用时，原料由螺旋挤出机的进料仓中进入，在对高粘度的塑料、填料含量较高的塑料、颗粒较大的塑料等挤出时，由于其粘性较大或者颗粒较大，容易堵塞进料口，导致挤出机无法正常进行挤出，且自然下落的速度有限，进料效率较低，进而导致生产成本增加，因此提出一种塑料挤出机的挤出螺旋顶出装置，以克服上述缺陷。When the extrusion screw ejector device of the plastic extruder in the prior art is in use, the raw materials enter from the feed bin of the screw extruder. When extruding high-viscosity plastics, plastics with high filler content, plastics with large particles, etc., the feed port is easily blocked due to their high viscosity or large particles, resulting in the extruder being unable to extrude normally, and the natural falling speed is limited, the feeding efficiency is low, and thus the production cost is increased. Therefore, an extrusion screw ejector device for a plastic extruder is proposed to overcome the above-mentioned defects.
