Description

Technical Field

[0001] The utility model relates to the technical field of page wheel manufacturing, and particularly relates to a cleaning mechanism for a die plate of a page wheel grinding disc for degumming and de-papering. Background Art

[0002] When producing abrasive sheet page wheel grinding discs, a die plate is required to perform 360-degree discharging, shaping, gluing, pressing, and burning on the abrasive sheet page wheel grinding discs. During the several-hour burning process, part of the glue on the page wheel grinding disc overflows and adheres to the die plate. Therefore, after the production of the page wheel grinding disc is completed, it is generally necessary to clean the glue and paper scraps on the die plate.
