AI Technical Summary

Technical Problem

Existing feeding devices often result in uneven feeding of recycled plastics due to the varying shapes and sizes of the recycled plastics. This leads to unstable pressure of the extruded plastic melt, which in turn affects the quality of the filaments and causes uneven filament thickness.

Method used

An extruder feeding device for a recycled plastic filament production line was designed. The device achieves mixing and processing functions through the cooperation of stirring blades and adjusting plates. The device also achieves telescopic adjustment and threaded connection through the cooperation of connecting shaft, telescopic rod and threaded rod. Combined with the use of heating plate and guide plate, the device ensures uniform plastic processing and stable conveying.

Benefits of technology

It achieves uniformity in the shape and size of recycled plastics, ensures the stability of plastic melt pressure, and improves the consistency of filament drawing quality and production efficiency.

Abstract

This utility model discloses an extruder feeding device for a recycled plastic filament production line, relating to the field of plastic processing equipment technology. It includes a workbench with a conveying pipe fixedly installed on its top. An extruder is fixedly connected to the right side of the conveying pipe, and a connecting frame is fixedly installed to the left side. This utility model utilizes a connecting shaft, adjusting plate, stirring blades, telescopic rod, and threaded rod in cooperation to drive a rotating column via a motor. The rotating column, through the connecting shaft, causes the adjusting plate to rotate. The stirring blades mounted on the adjusting plate then rotate and stir the internal plastic, achieving the function of stirring and processing. Simultaneously, the telescopic rod extends and retracts, pushing the adjusting plate outwards and further adjusting the stirring range of the stirring blades. Under the synergistic action of the stirring mechanism, the plastic raw materials are fully stirred and mixed, thereby achieving uniformity in shape and size.
