[0026] During operation, the roller is placed on the base 1, and then the damping shaft 14 is rotated to drive the worm 13 to rotate, and the worm 13 drives the half gear 12 to rotate, which can drive the turntable 5 to rotate, and the turntable 5 drives the connecting plate 6 to rotate. With the cooperation of the guide groove 11 and the guide block 10, the T-block 8 can slide in the I-shaped groove 7, thereby driving the clamping block 9 to slide, so that the clamping block 9 is against the inner wall of the roller, and then the roller is corrected by starting the correction mechanism 3, so that rollers of different diameters can be corrected, and the application range is wide.

[0027] There are three T-blocks 8, and the three T-blocks 8 are arranged at equal angles with the center of the fixed seat 4 as the center;

[0028] During operation, by providing three T-blocks 8, the clamping block 9 can stably fix the roller shaft to avoid shaking.

[0029] A guide block 10 is fixedly connected to one side of the lower surface of each of the three T-shaped blocks 8, a guide groove 11 is provided on the upper surface of the connecting plate 6, and the outer wall of the guide block 10 is slidably connected to the inner wall of the guide groove 11;

[0030] During operation, when the turntable 5 drives the connecting disk 6 to rotate, since a guide groove 11 is provided on the connecting disk 6 and the guide groove 11 is provided obliquely, when the connecting disk 6 rotates, under the action of the guide groove 11, the guide block 10 can be pulled to slide in the guide groove 11, so that the guide block 10 can pull the T-shaped block 8 to slide in the I-shaped groove 7.

[0031] The correction mechanism 3 includes a hydraulic rod 301 and a correction plate 303. One end of the hydraulic rod 301 is fixedly connected to both sides of the lower surface of the fixed frame 2. The output end of the hydraulic rod 301 is fixedly connected to a connecting plate 302. The connecting plate 302 is provided with a correction plate 303.

[0032] During operation, the connecting plate 302 is driven to move downward by starting the hydraulic rod 301, and then the connecting plate 302 moves downward with the correction disk 303. Since the center of the connecting plate 302, the center of the correction disk 303 and the center of the fixing seat 4 are on the same axis, the correction disk 303 can be aligned with the roller shaft when moving downward, so that the correction disk 303 is sleeved on the outer wall of the roller shaft. The correction disk 303 is a hollow flat-top cone, and the inner diameter of the small diameter end is the same as the outer wall diameter of the roller shaft. Therefore, after the correction disk 303 is pressed down and sleeved into the outer wall of the roller shaft, the roller shaft can be corrected into a circle that meets the requirements.

[0033] The outer wall of the correction plate 303 is fixedly connected with mounting blocks 305 on both sides, and the two mounting blocks 305 are provided with screw holes 306 on the sides away from each other. The inner walls of the two screw holes 306 are threadedly connected with screw rods 304, and the outer walls of the two screw rods 304 are rotatably connected to the two sides of the connecting plate 302 respectively.

[0034] During operation, when it is necessary to calibrate rollers of different diameters, the screw rod 304 is rotated to disengage the screw rod 304 from the screw holes 306 of the mounting blocks 305 on both sides of the correction disk 303, and then the correction disk 303 is replaced with a correction disk 303 that matches the roller, and the screw rod 304 is rotated and tightened into the screw holes 306 of the mounting blocks 305 to install and fix the correction disk 303, thereby achieving the ability to calibrate rollers of different diameters, with a wide range of applications.

Since the connecting plate 6 is provided with a guide groove 11, and the guide groove 11 is obliquely provided, when the connecting plate 6 rotates, under the action of the guide groove 11, the guide block 10 can be pulled to slide in the guide groove 11, so that the guide block 10 can pull the T-block 8 to slide in the I-shaped groove 7, and then the T-block 8 drives the clamping block 9 to slide, so that the clamping block 9 can be pressed against the inner wall of the roller shaft, and then the connecting plate 302 is driven to move downward by starting the hydraulic rod 301, and then the connecting plate 302 moves downward with the correction plate 303. Due to the center of the connecting plate 302 and the correction plate 303, The center of 303 and the center of the fixed seat 4 are on the same axis, so the correction disk 303 can be aligned with the roller when it moves downward, so that the correction disk 303 is sleeved on the outer wall of the roller, and the correction disk 303 is a hollow flat-top cone, and the inner diameter of the small diameter end is the same as the outer wall diameter of the roller, so after the correction disk 303 is pressed down and sleeved into the outer wall of the roller, the roller can be corrected into a circle that meets the requirements. When it is necessary to correct rollers of different diameters, the screw 304 is rotated to disengage the screw hole 306 of the mounting block 305 on both sides of the correction disk 303, and then the correction disk 303 is replaced with a correction disk 303 that matches the roller, and the screw 304 is rotated and tightened into the screw hole 306 of the mounting block 305, and the correction disk 303 is installed and fixed, thereby realizing the correction of rollers of different diameters, and having a wide range of applications.
