A threaded hole is arranged on one side of the inner wall of the adjusting cavity. An adjusting screw 203 is arranged inside the threaded hole. The outer wall of the adjusting screw 203 is threadedly connected with the inner wall of the threaded hole. The adjusting screw 203 rotating clockwise in the threaded hole will drive the T-shaped rotating rod 202, the movable block 201, the connecting block 205 and the adjusting block 206 to move in a direction away from the threaded hole. The adjusting screw 203 rotating counterclockwise in the threaded hole will drive the T-shaped rotating rod 202, the movable block 201, the connecting block 205 and The adjusting block 206 moves in the direction of the threaded hole, and a rotating block 204 is provided at one end of the adjusting screw 203, and the rotating block 204 is fixedly connected to one end of the adjusting screw 203. A strip-shaped auxiliary groove is provided on the front of the rotating block 204, and the T-shaped rotating rod 202 is fixedly connected to the other end of the adjusting screw 203. A strip-shaped hole is provided on the top of the inner wall of the adjusting cavity, and a connecting block 205 is provided in the inner cavity of the strip-shaped hole. A limited sliding hole is provided on the front of the connecting block 205, and a limited sliding rod 207 is slidably sleeved in the inner cavity of the limited sliding hole. The limited sliding rod 207 and the limited sliding hole are used to ensure that the connecting block 205 and the adjusting block 206 move smoothly. The limited sliding rod 207 is fixedly connected to the inner cavity of the strip-shaped hole. An adjusting block 206 is provided on the top of the connecting block 205, and the connecting block 205 is fixedly connected between the movable block 201 and the adjusting block 206.

When using the leveling mechanism 4, first turn the rope drum 401 downward, then rotate the combination block 404 counterclockwise until the combination block 404 is separated from the rope drum 401, and then observe whether the leveling rope 402 and the multi-section shaft roller are vertical to determine whether the multi-section shaft roller is horizontal.

[0028] Working principle of this utility model:

[0029] When the assembly groove on the multi-section shaft roller does not match the length of the assembly block in the printing press, first use a flat-blade screwdriver to drive the rotating block 204 and the adjusting screw 203 to rotate counterclockwise. The adjusting screw 203 rotating counterclockwise in the threaded hole will drive the T-shaped rotating rod 202, the movable block 201, the connecting block 205 and the adjusting block 206 to move in the direction of the threaded hole. In the above process, the position of the adjusting block 206 needs to be understood in real time through the arc scale plate 3. When the space in the concave direction of the adjusting block 206 in the assembly groove matches the length of the assembly block in the printing press, stop rotating the rotating block 204. At this time, the space adjustment work of the assembly groove on the multi-section shaft roller is completed, so that the assembly groove on the multi-section shaft roller can match the assembly blocks of different lengths, thereby improving the applicability of the multi-section shaft roller.
