The utility model discloses a synchronous belt surface glue edge
grinding machine, which relates to the technical field of synchronous belt production, and comprises a transverse rail, a rotating seat rotatably connected to the upper side of one end of the transverse rail, a plurality of synchronous wheels with different wheel diameters arranged on the front side of the rotating seat, a movable seat which slides left and right arranged on the upper side of the transverse rail, and a movable seat which slides left and right arranged on the movable seat. A vertical seat is fixedly installed on the upper side of the movable seat, a sliding seat sliding up and down is arranged on the vertical seat, and a plurality of synchronous wheels with different wheel diameters are correspondingly arranged on one side of the sliding seat. According to the synchronous belt tensioning device, a plurality of adjustable assemblies such as the moving seat, the sliding seat and the rotating seat can be adjusted according to synchronous belts of different specifications, the synchronous belt tensioning device adapts to the synchronous belts of different lengths and widths, the universality of the device is improved, the synchronous belts can be accurately tensioned through cooperation of the synchronous wheels, the clamping blocks and the sliding seat, and the production efficiency is improved. It is guaranteed that the synchronous belt is in an ideal tension state all the time in the edge
grinding process, the uniform edge
grinding effect is provided, synchronous belts of different specifications can be precisely processed, and various production requirements are met.
