Description

Technical Field

[0001] The utility model relates to the technical field related to feeding devices, in particular to a feeding device for hot-melt processing of plastic pipes. Background Art

[0002] Plastic granules are often used as raw materials when making plastic pipes. Before making plastic pipes, the plastic granules need to be melted in a hot melt tank until they are molten. The molten injection molding raw materials are then stirred. After stirring evenly, they are extruded and molded.

[0003] However, the existing hot melt tank generally has an iron removal device added inside the feeding device when in use, which is used to remove iron impurities inside the plastic pellets to prevent damage to the subsequent extrusion molding device.
