Description

Technical Field

[0001] The utility model relates to the technical field of plastic pipe production equipment, in particular to a constant temperature melting device for plastic raw materials. Background Art

[0002] Plastic raw materials are mainly divided into thermoplastic and thermosetting plastics according to the molecular structure of synthetic resins. Thermoplastic plastics refer to plastics that remain plastic after repeated heating, while thermosetting plastics mainly refer to plastics made from synthetic resins that are hardened by heating. In the research and development, production and inspection of plastic raw materials, stirring and dispersing equipment is required to make plastic raw materials that can distinguish different textures. In order to extract plastic raw materials of the same high quality and facilitate the subsequent manufacture of plastic raw materials, a plastic raw material stirring device can be introduced.

[0003] The existing constant temperature melting device for plastic raw materials has some disadvantages. First, the plastic raw materials are melted unevenly and the internal particles are not completely melted, which is not conducive to melting the plastic raw materials. This causes the quality of the plastic raw rubber to be unstable, which will affect the quality of the melted plastic. Secondly, it is inevitable that the material will be blocked during discharge, which affects the discharge. In addition, the device is unstable and not conducive to maintenance, which affects the service life. Utility Model Content
