Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of conveying roller, in particular to a conveying roller alignment auxiliary device and a conveying roller alignment method using the same. BACKGROUND

[0002] After long-term use, some conveying rollers on the conveying roller may have a certain positional deviation, and when the conveying roller bearing part fails, the setting position of the conveying roller will also change to some extent after recovery and repair. Since the transmission distance of the conveying roller is relatively long, any slight deviation will cause a huge deviation in the final conveying position of the conveyed object. Therefore, when the conveying roller is installed, repaired or replaced, the conveying roller needs to be accurately positioned.

[0003] The conventional conveying roller positioning method determines the axial position of the conveying roller by an auxiliary positioning line and adjusts the level by a level gauge. There is no linkage between the axial positioning and the horizontal adjustment, and there is still a certain correction error. In addition, the parallelism between the conveying rollers is not easy to control, and there is also a correction error between the conveying rollers, which is not conducive to the accurate conveying of the conveyed object on the conveying roller.
