The rotating component is composed of a rotating rod 21, a worm wheel 19, and a double-section worm 20. Among them, the two rotating rods 21 are respectively fixedly connected to the two rotating rollers 4. One end of each of the two rotating rods 21 is fixedly connected to a worm wheel 19. On one side of the two worm wheels 19, there is a meshing connection with a double-section worm 20. On the outer surface of the installation frame 1, a driving shell 9 is fixedly installed. On the outer surface of the driving shell 9, a rotating motor 10 is fixedly installed through a fixing frame. And the output end of the rotating motor 10 is connected to the double-section worm 20. In this way, by driving the rotating motor 10, the rotating motor 10 can drive the double-section worm 20 to rotate. When in use, a rubber cylinder can be placed between the two rotating rollers 4. When the two rotating rollers 4 rotate synchronously and in the same direction, at this time, the contact surfaces of the two rotating rollers 4 with the rubber cylinder have frictions in opposite directions. Thus, the rotation of the two rotating rollers 4 can drive the rubber cylinder in contact with them to rotate in opposite directions. The rubber cylinder during rotation is convenient for subsequent grinding of its surface. At the four corners of the bottom surface of the installation frame 1, there are support rods 3 for supporting the installation frame 1. The bottom ends of the support rods 3 are fixedly connected to a base 2;

[0025] When using this device, place this device at a designated position, place the rubber cylinder to be ground between the two rotating rollers 4 and make contact with the two rotating rollers 4. Drive the rotating motor 10. The rotating motor 10 drives the double-section worm 20 to rotate. The double-section worm 20 drives the two worm wheels 19 to rotate synchronously. The two worm wheels 19 drive the two rotating rollers 4 to rotate synchronously and in the same direction. When the two rotating rollers 4 rotate, the contact surfaces of the two rotating rollers 4 with the rubber cylinder have opposite frictions. At this time, the rubber cylinder can be driven to rotate in opposite directions on the two rotating rollers 4. The rubber cylinder during rotation is convenient for subsequent grinding of its surface;

[0026] As a further implementation manner of this embodiment, as Figures 1-3As shown in the figure, an outer skin grinding assembly is provided above the two rotating rollers 4.
