The specific structure of the first and

second reversing mechanisms

30 and 40 is as follows: the first reversing mechanism 30 includes a first driving wheel 31 and a first driven wheel 32, and the first driving wheel 31 and the first driven wheel 32 are in transmission connection through a first belt 33. The second reversing mechanism 40 includes a second driving wheel 41 and a second driven wheel 42, and the second driving wheel 41 and the second driven wheel 42 are in transmission connection through a second belt 43. A first rotating shaft 11 and a second rotating shaft 12 are respectively disposed on two sides of the frame 10, wherein the first rotating shaft 11 is used for mounting a first driving wheel 31 and a second driving wheel 41, and the second rotating shaft 12 is used for mounting a first driven wheel 32 and a second driven wheel 42. The first rotating shaft 11 is driven to move by a servo motor 50. In order to ensure the transmission speed of the first reversing mechanism 30 is different from that of the second reversing mechanism 40, the diameter of the first driving wheel 31 is greater than that of the second driving wheel 41, the diameter of the first driven wheel 31 is greater than that of the second driven wheel 42, and the diameter of the first driving wheel 31 is greater and the transmission speed is higher at the same rotation speed.

The first reversing mechanism 30 and the second reversing mechanism 40 drive the tiles to turn: the servo motor 50 drives the first driving wheel 31 to rotate, and drives the first driven wheel 32 to rotate through the first belt 33; similarly, the servo motor 50 rotates the second driving pulley 41, and the second driven pulley 42 is rotated by the second belt 43. At this time, since the running speed of the first reversing mechanism 30 is higher than that of the second reversing mechanism 40, the tiles on the first reversing mechanism 30 and the second reversing mechanism 40 can be turned, and the tiles rotate clockwise from the first reversing mechanism 30 to the second reversing mechanism 40, so that the turning of the tiles is completed.

In order to make the tile steering accurate and avoid falling the tile, the utility model discloses a change is made to the support plate at the bottom of the belt, wherein a first support plate 60 for tensioning the first belt 33 and a second support plate 70 for tensioning the second belt 43 are arranged on the frame 10, the first support plate 60 and the second support plate 70 are arc-shaped and are arched upwards; the first support plate 60 includes a first support portion 61, a second support portion 62, and a third support portion 63 disposed along the tile traveling direction, and the second support plate 70 includes a fourth support portion 71, a fifth support portion 72, and a sixth support portion 73 disposed along the tile traveling direction; the arching height of the first support 61 is higher than that of the fourth support 71, the arching height of the second support 62 is equal to that of the fifth support 72, and the arching height of the third support 63 is lower than that of the sixth support 73.
