Adhesive tape releasing mechanism of adhesive tape sticking disc

The utility model relates to the technical field of rubberizing processing, in particular to a rubberizing disc rubberizing mechanism which comprises a feeding shaft, a rubberizing disc, a first clamping plate and a second clamping plate, the first clamping plate is perpendicular to a center shaft of the feeding shaft, the second clamping plate is fixedly connected to the feeding shaft, and the rubberizing disc is connected with the first clamping plate and the second clamping plate in an abutting mode. The plastic tray fixing device is simple in structure and reasonable in design, the plastic tray is clamped through the first clamping plate and the second clamping plate, fixing of the plastic tray is achieved, when the plastic tray is replaced, only the first clamping plate needs to be taken down, the plastic can be replaced, and the plastic tray fixing device is simple in structure, convenient to use and high in practicability. And then, the first clamping plate is clamped in, and the second clamping plate
