Description

Tube core clamping device for winding medical adhesive tape Technical Field The utility model relates to the technical field of medical adhesive tape processing, in particular to a tube core clamping device for winding a medical adhesive tape. Background In the prior art, the tube core of the medical adhesive tape needs to be clamped and fixed in the production and winding process of the medical adhesive tape. At present, many things adopt a mechanical structure to manually adjust the tensioning so as to realize clamping of the tube cores, and the operation efficiency is low, so that the production efficiency is influenced. In addition, the cylinder or the electric cylinder is adopted to clamp the tube core, but because the turntable needs to rotate, the electric cylinder and the cylinder also need to rotate along with the turntable to stably wind the adhesive tape, and the electric cylinder and the cylinder are connected with an electric wire, an air pipe and the like outwards, so that in order to realize the rotation, electric brushes, rotary joints and the like are adopted to transfer current and air flow. However, in the use process of the structure, the service life is relatively short, the problems of frequent faults and the like occur, frequent replacement and maintenance are needed, the production efficiency is reduced, and the production cost is increased.
