[0002] Paper machines need to transport paper during operation, and in order to prevent paper from deflecting during transport, correction rollers are needed to correct the deflected paper. Most existing correction rollers have complex structures and cannot simply and effectively complete the paper correction work, thus affecting the smoothness of paper transport. In addition, most existing correction rollers have a fixed height, which is not convenient for height adjustment, making it difficult to transport paper of different heights, limiting their scope of application.

[0003] Therefore, it is necessary to provide a correction roller for a papermaking machine to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0017] See also Figures 1 to 4A correction roller for a papermaking machine is shown, comprising a roller frame 1, in which a roller body 2 is rotatably installed, a support seat 3 is arranged below the roller frame 1, side plates 4 are arranged on both sides of the bottom of the support seat 3, and the bottoms of the two side plates 4 are connected to the same base 5, a cylinder 6 is arranged at the bottom of the support seat 3, and the output shaft of the cylinder 6 is connected to a lifting plate 7, a reduction motor 8 is fixed on the top of the lifting plate 7, and the output shaft of the reduction motor 8 is connected to a first bevel gear 9, a first rotating rod 10 is fixed at the bottom of the roller frame 1, the first rotating rod 10 is rotatably connected to the support seat 3 through a bearing, the bottom of the first rotating rod 10 passes through the support seat 3 and is connected to a second bevel gear 11, and the second bevel gear 11 is meshed with the first bevel gear 9.

[0018] Furthermore, arc-shaped slide grooves 12 are provided on both sides of the top of the support seat 3, and the center of the arc-shaped slide groove 12 is on the same straight line as the central axis of the first rotating rod 10. Slide blocks 20 are provided on both sides of the bottom of the roller frame 1, and the two slide blocks 20 are respectively slidably set in the two arc-shaped slide grooves 12.

[0019] The arc-shaped slide groove 12 and the slider 20 are arranged to ensure the stability of the roller frame 1 rotating on the top of the support seat 3 .
