塑料颗粒机是如何工作的？

塑料加入塑料造粒机的料斗后，料斗会顺畅地滑落到螺杆上，并被螺纹咬住。随着螺杆的旋转，螺纹被强制向前推向机头，形成机械输送过程。

当塑料从进料口流向机器头时，螺杆的螺纹深度逐渐减小，由于过滤网、歧管和机头的阻力，在塑化过程中形成高压，材料被压得非常紧。

密实化改善了其导热性，并帮助塑料快速熔化。同时，逐渐增加的压力导致原本存在于颗粒之间的气体从通气孔排出。

在压力上升的同时，塑料一方面受到外部加热。另一方面，在压缩、剪切和搅拌的运动过程中，塑料自身由于内部摩擦产生大量热量。在外力和内力的共同作用下，塑料的温度逐渐升高，其物理状态也经历了玻璃态、高弹态和粘流态的变化。

Generally speaking, in the feeding, the glass state is mainly in the middle portion of the compression section where the screw thread is gradually reduced, the material is mainly in a high elastic state, and gradually melts, and the material is in a viscous state at the rear and the squashing section of the compression section.

This is that the plastic has been completely plasticized, and the plasticized plastic is pressed, quantitatively and uniformly continuously extruded from the machine head by screw inference.
