Roller flexibility correction device with balancing device

Abstract

The invention discloses a roller flexibility correction device with a balancing device. The roller flexibility correction device comprises a center cylinder, an air compressor is fixedly mounted in the center cylinder, barrels are uniformly distributed on the outer periphery of the center cylinder, each barrel is partitioned by a partition plate to form a mounting portion and a telescoping portion, an air cylinder block is mounted in each mounting portion, an outlet of the air compressor is connected with each air cylinder block, and a piston rod of each air cylinder block penetrates through the corresponding partition plate to enter the corresponding telescoping portion. The telescoping portions are provided with telescoping holes integrally in conical frustum shapes, ejector rods connected with the air cylinder blocks are fittingly arranged in the telescoping holes with small upper-end diameters and large lower-end diameters. Hollow supporting barrels are uniformly mounted along the periphery of the outer wall of the center cylinder, springs are internally sleeved by the supporting barrels which are provided with supporting rods, one end of each supporting rod is inserted into the corresponding supporting barrel to make contact with the corresponding spring while the other end of each supporting rod is connected with a balancing ring, and each balancing ring is provided with a mounting groove for mounting of a balancing rod. The roller flexibility correction device can be steadily mounted in a roller to correct flexibility deformation of the roller, and precision in correction of flexibility deformation of the roller is improved.

Description

technical field [0001] The invention relates to a roll body flexible deformation correction device, in particular to a roll body flexibility correction device with a balance device for correcting the roll body flexible deformation. Background technique [0002] The roll body is an indispensable device in various large-scale equipment, such as paper machines, ball mills, etc., and with the improvement of production efficiency, the diameter of the roll body in paper machines, ball mills, etc. is getting larger and larger. In order to ensure that the equipment Safe operation requires that the rollers rotate with as little deflection at the center as possible, so that the processing quality can be guaranteed without causing harmful vibrations. [0003] At present, the traditional two-stage dynamic balancing method for large-diameter rollers cannot eliminate the deflection at the center of the rollers, and because the rollers have large diameters and high rotational speeds, the b...
