When the uncoiler drum device provided by the preferred embodiment is applied, the hydraulic cylinder drives the pull rod assembly to axially move, and particularly, the axial movement of the rectangular pyramid 6 drives the plunger 5 and the sector plate 3 to radially move under the limitation of the retainer 1 and the holding head 10, so that the purpose of expanding and reducing the diameter of the drum is achieved. Due to the positioning effect of the semicircular keys 11 on the rectangular pyramid 6, the plunger 5 is convenient to mount, and the stress on the contact parts (namely the dovetail groove and the T-shaped guide rail) of the rectangular pyramid 6 and the plunger 5 caused by the rotation of the pull rod 8 is eliminated. The rectangular pyramid 6 in the pull rod assembly is a relatively independent structure, when one of the pull rod assemblies is damaged, only the damaged rectangular pyramid needs to be replaced, the cost is low, and the service life of the winding drum is prolonged. The L-shaped structure of the retainer 1 is beneficial to preventing the fan-shaped plate 3 from accidentally falling off to cause damage to other equipment.
