Description

TECHNICAL FIELD

[0001] The application relates to the technical field of recycling granulators, in particular to a single-screw recycling granulator. BACKGROUND

[0002] The recycling granulator is a device for recycling waste plastics or other polymer materials, which converts waste plastics into high-quality regenerated particles through melting, filtering, cutting and other processes. The particles can be used to manufacture new plastic products. The recycling granulator not only helps reduce environmental pollution, but also reduces raw material costs, and is an indispensable device in the plastic recycling industry.

[0003] In the recycling granulator, there are mainly two types: single-screw and double-screw granulators. Single-screw granulators are favored due to their simple structure, easy operation and low maintenance cost. They are usually suitable for processing relatively uniform materials and have low energy consumption, suitable for small and medium-sized production needs.

[0004] Although the single-screw recycling granulator has the above advantages, in actual production, due to the different sizes and hardness of the materials to be processed, the single-screw granulator often cannot provide sufficient shear force, which leads to uneven plasticization of the materials, and the screw cannot completely shear and melt the materials, which easily causes blockage. This situation not only affects production efficiency, but also can cause product quality to decline, causing economic losses to enterprises. Therefore, the application provides a single-screw recycling granulator. Invention content

The elastic rebound of the damping spring 29 can preliminarily decompose and reduce the vibration force. Then the extruded sliding column 28 will slide in the fixed column 27 and extrude the damping block 30. The damping block 30 can buffer and reduce the vibration again, so as to greatly improve the service life of the device and reduce the spread of noise.
