[0019] The following will be described in detail with reference to the embodiments of the present utility model with reference to the drawings. Specific Embodiments

[0020] The present utility model will be further described below with reference to the drawings and embodiments:

[0021] As Figures 1-4 shown, a roller automatic centering device includes a bottom plate 1. On the front and rear sides of the top of the bottom plate 1, installation boxes 2 with bottom openings are correspondingly provided. On the top of the installation box 2, a pair of sliding holes 3 are provided. A support frame 4 is slidably arranged in the sliding holes 3. The support frame 4 includes a backing plate 401. On the front and rear sides of the top of the backing plate 401, roller support plates 402 are correspondingly provided. On the left and right sides, reinforcement plates 403 are provided. The edges of the reinforcement plates 403 and the roller support plates 402 are fixedly connected;

[0022] A power mechanism for driving the support frame 4 to slide is provided in the installation box 2. The power mechanism includes a pair of single-axis robots 8 arranged in the installation box 2. The single-axis robot 8 is hollow inside, and screws are connected to the two sides of the single-axis robot 8 for rotation. A motor 9 is provided on one side of the single-axis robot 8 to drive the screw to rotate. A moving seat 10 is threadedly connected to the screw. Strip holes 11 are provided on the front and back sides of the single-axis robot 8. The front and back sides of the moving seat 10 pass through the strip holes 11 and slide along the strip holes 11. The pad 401 is fixed to the top of the moving seat 10 by bolts. A metal sheet 14 is provided on one side of the moving seat 10. Proximity switches 15 corresponding to the metal sheet 14 are provided at both ends of one side wall of the single-axis robot 8. A heat dissipation opening 13 corresponding to the motor 9 is provided on the side wall of the installation box 2; the setting of the metal sheet 14 and the proximity switch 15 can limit the moving distance of the moving seat 10.

[0023] The top of the support frame 4 is rotatably connected to the support roller 5, and the top of the opposite surface of the roller support plate 402 is rotatably connected to the rotating shaft 12. The support roller 5 is fixedly sleeved in the middle of the rotating shaft 12, and the drum 6 is supported by the support roller 5. The support frame 4 is provided with an electromagnetic brake 7 for braking the support roller 5. The housing of the electromagnetic brake 7 is installed on the outside of the roller support plate 402, and the brake disc is installed on the rotating shaft 12.

[0024] When the present invention is working, the roller 6 is placed on the supporting roller 5 for support, the motor 9 is started, and the supporting frame 4 is driven to slide left and right in the sliding hole 3. When the two supporting frames 4 on the installation box 2 slide toward the opposite side, the roller 6 rises. When the two supporting frames 4 slide toward the opposite side, the roller 6 falls. After the centering is adjusted, the electromagnetic brake 7 is started to brake the supporting roller 5 to prevent the roller 6 from rotating. When the roller 6 needs to be rotated to process different surfaces, the electromagnetic brake 7 is turned off and the roller 6 can be pushed.

[0025] The utility model can adjust the height of the roller 6 to achieve centering, and the adjustment operation is simple and quick. The roller 6 can also be rotated during processing to adjust the position of the roller 6, which is easy to use.
