Abstract
The invention discloses a coiling device with automatic detection for expansion and constriction of a core shaft. The coiling device comprises a driving motor (1), a core shaft expanding-constricting hydraulic device (2), a gearbox (3) and a coiling core shaft body (4) and is characterized in that the rear side of the coiling core shaft body (4) is provided with a core shaft expanding-constricting automatic-detection device. The core shaft expanding-constricting automatic-detection device monitors the expansion and constriction state of the core shaft in real time. Once the core shaft generates a constriction sign in the coiling process, the sign can be discovered in time so that a system is stopped, and therefore the problem that uncoiling cannot be conducted as the core shaft has been constricted in the coiling process is avoided.
