Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of feeding devices, and more specifically, to a feeding device for an extruder. Background Art
[0002] Screw extruder is a commonly used equipment for plastic processing. Its raw materials include granular materials, powder materials, etc. Existing screw extruders often use a screw structure, which allows the material to gradually change into linear motion as the screw rotates, move toward the head, and cooperate with the body to compress, generate heat, soften, stir, and mix the materials.
[0003] When the extruder is working, the temperature of the hopper will rise due to various factors such as working temperature, cooling efficiency, and long-term friction heat generated by the material during feeding. The low-melting-point additives in the material will melt and accumulate on the inner wall of the hopper. If it is not cleaned in time, it may cause material blockage, affecting people's work. When the material is fed, it may cause arching, which will prevent the raw material from falling into the screw of the extruder inlet, affecting production efficiency. In this regard, we propose an extruder feeding device. Utility Model Content
