Description

Technical Field

[0001] The utility model belongs to the technical field of carbon fiber tube production demoulding machines, in particular to a demoulding machine with a multi-station structure. Background Art

[0002] Carbon fiber tubes, also known as carbon fiber tubes or carbon tubes, are made by pre-impregnating carbon fiber with styrene and polyester resins and then heating, curing, and pultruding. Carbon fiber tubes offer advantages such as high strength, long life, corrosion resistance, lightweight, and low density. They are widely used in industrial machinery rollers, aerospace, medical, and PC equipment shafts. The production of carbon fiber tubes involves several steps: material preparation, blanking, cloth attachment, rolling, tape wrapping, curing, demolding, stripping, grinding, cutting, and coating. The demolding process for carbon fiber tubes is typically a single-station setup, where operators place a set of carbon fiber tube molds inside a demolding machine to remove the tubes. This single-station demolding machine is ineffective in improving demolding efficiency, which determines overall carbon fiber tube production efficiency, impacting manufacturers' overall production schedule and hindering their competitiveness. Furthermore, improving demolding efficiency requires increased labor and equipment costs, making it difficult to maintain competitiveness.

[0003] In summary, there are some problems in the use of a single-station demoulding machine for demoulding carbon fiber tubes, so it is hoped to propose a new structure to solve the above technical problems. Utility Model Content
