Pipe core fixing device and winding equipment

A tube core fixing device comprises a base plate, a jacking support and a driving component, the jacking support is perpendicularly arranged on the base plate and comprises a plurality of jacking blocks, the jacking blocks are evenly arranged in the circumferential direction of the base plate, a sliding component is arranged on the surface of the base plate in the radial direction of the base plate, and each jacking block is arranged on the sliding component in a sliding mode. The driving part is arranged in the jacking support and acts on the inner side faces of the multiple jacking blocks to drive the multiple jacking blocks to slide in a reciprocating mode in the radial direction of the chassis, so that the multiple jacking blocks are relatively close to or away from each other to adjust the diameter of the jacking support. According to the tube core fixing device, the diameter of the tube core jacking support can be adjusted according to the fixing requirements of tube cores with different diameters so as
