Description

Technical Field

[0001] The utility model relates to a pipe making device, more specifically, to a tape reel device for winding a prepreg tape reinforced composite pipe. Background Art

[0002] During the production of prepreg tape-reinforced composite pipes, prepreg tape needs to be wrapped around the outer surface of the inner pipe for reinforcement. This process requires the use of a prepreg tape reel. Existing reels have a simple structure, with multiple bolts fastening the left and right wheels. The wider the prepreg tape, the longer the required fastening bolts, requiring frequent bolt replacement, which is very inconvenient. Furthermore, conventional reels have cylindrical holes for mating with the winding machine's belt shaft. To facilitate disassembly, a clearance fit is often used, with a single nut locking mechanism. During composite pipe production, the reel rotates on its own to unwind the tape, while also rotating around the winding machine's axis. Centrifugal force can loosen the reel, causing the prepreg tape to slip axially, changing the winding angle and gap of the prepreg tape, and thus affecting the pressure-bearing performance of the composite pipe.
