Description

Technical Field

[0001] This utility model relates to the field of composite pipe production technology, and in particular to a feeding device for the production of flexible composite pipes. Background Technology

[0002] Flexible composite pipes are piping systems composed of multiple layers of different materials. They possess high flexibility, pressure resistance, and corrosion resistance, and are widely used in industries such as petroleum, natural gas, chemical, HVAC, and construction. They are made from a combination of different types of plastics, metals, and rubber, combined through a special manufacturing process to form pipes with unique properties. Their ease of installation and adaptability make them an indispensable material in modern piping systems. In the production of flexible composite pipes, the materials need to be mixed and proportioned; therefore, material transportation is crucial. Current feeding methods include screw conveyors and belt conveyors, but each has its shortcomings. For example, screw conveyors typically have a closed shaft, making subsequent maintenance inconvenient. Therefore, this invention proposes a feeding device that enables proportioned feeding of materials. Using screw conveyor feeding allows for precise control of the material ratio and facilitates subsequent maintenance. Utility Model Content

Along the axial direction of the transmission shaft, the surface of the transmission shaft is cleaned, i.e., the blocked material is removed. With the rotation of the transmission shaft, the cleaning operation at each position is realized. Attached Figure Description
