By setting the clamping block 205, the propulsion assembly is adjusted to push the clamping cylinder 209 to one side. In the process of pushing the clamping cylinder 209 to one side, the clamping block 205 moves with the clamping cylinder 209. In the process of moving, the surfaces of several groups of clamping blocks 205 are squeezed by the fixed cylinder 200 at the same time, and then several groups of clamping blocks 205 are squeezed inward at the same time to clamp one end of the roller, thereby improving the convenience of the staff in clamping the roller.

[0027] Furthermore, the propulsion assembly includes a square hole 210 opened on the surface of the clamping cylinder 209, and the inner cavities of the two groups of square holes 210 are slidably connected with a group of transmission rods 207. The surface of the transmission rod 207 is fixedly sleeved with a cam 212, and the surface of the cam 212 abuts against the bottom of the inner wall of the clamping cylinder 209. The surface of the fixed cylinder 200 is provided with a groove 208. One end of the transmission rod 207 passes through the inner wall of the fixed cylinder 200 and extends to the inner cavity of the groove 208. Through the setting of the transmission rod 207, it is convenient for the staff to rotate the transmission rod 207, thereby driving the cam 212 to rotate, and pushing the clamping cylinder 209 to one side.

[0028] Furthermore, a worm wheel 206 is fixedly sleeved on the surface of one end of the transmission rod 207 in the groove 208, a worm 204 is meshed on the surface of the worm wheel 206, one end of the worm 204 is rotatably connected to an inner wall of one side of the groove 208, the other end of the worm 204 penetrates the inner wall of the groove 208 and extends to the outside of the fixed cylinder 200, the other end of the worm 204 is fixedly connected to a turntable 201, and a protective shell 202 for closing the groove 208 is fixedly connected to the surface of the fixed cylinder 200.

Through the setting of the fixed column 300 and the sliding rod 302, the height of the U-shaped block 303 can be adjusted according to the different rollers being processed.

[0032] Furthermore, the inner arc surface of the U-shaped block 303 is rotatably connected to the fixed pulley 304 , and through the setting of the fixed pulley 304 , one end of the roller abuts against the surface of the fixed pulley 304 , thereby reducing the friction between the roller and the surface of the U-shaped block 303 .

[0034] First, loosen the first bolt 301, slide the sliding rod 302 upward, adjust the U-shaped block to a suitable height, then take out the roller, place one end of the roller on the inner arc surface of the U-shaped block 303, insert the other end of the roller into the inner cavity of the clamping cylinder 209, and rotate the turntable 201, drive the worm wheel 206 to rotate through the worm 204, and then drive the cam 212 on the surface of the transmission rod 207 to rotate, so as to push the clamping cylinder 209 to one side. In the process of pushing the clamping cylinder 209 to one side, the clamping block 205 moves with the clamping cylinder 209. During the movement, the surfaces of several groups of clamping blocks 205 are squeezed by the fixed cylinder 200 at the same time, and then several groups of clamping blocks 205 are squeezed inward at the same time, so as to clamp one end of the roller, and a rubber pad 211 is installed on the surface of the clamping block 205 to prevent one end of the roller from being clamped during the clamping process.
