Device for correcting flexibly-deformed rotary roller and provided with balancing device

Abstract

The invention discloses a device for correcting a flexibly-deformed rotary roller and provided with a balancing device. The device comprises a barrel, wherein the outer wall of the barrel is provided with a hollow ejection rod in the peripheral direction, the ejection rod is connected with a supporting rod through threads, and the end of the supporting rod is connected with an arc-shaped supporting plate. An oil pump and an oil tank are fixedly installed in the barrel, an inlet of the oil pump is communicated with the oil tank, an outlet of the oil pump is connected with an inlet of a flow divider valve, piston cylinder bodies identical to outlets of the flow divider valve in number are evenly installed on the outer wall of the barrel in the peripheral direction, liquid inlets of the piston cylinder bodies are communicated with the outlets of the flow divider valve, liquid outlets of the piston cylinder bodies are communicated with the oil tank, piston rods of the piston cylinder bodies are connected with supporting rings, pressure sensors are installed on the faces of the supporting rings, in contact with the roller, and installing grooves for balancing rods to be installed are further formed in the supporting rings. The device can ensure fitting stability between the balancing rods and the inner wall of the roller, and the problem that the correction accuracy is influenced by centrifugal force is eliminated.

Description

technical field [0001] The invention relates to equipment for correcting the flexible deformation of a roller body, in particular to a device for correcting the flexible deformation of a rotating roller body with a balancing device. 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 ...

AI Technical Summary

Problems solved by technology

[0007] The present invention aims to solve the correction accuracy caused by the low bonding stability between the balance bar and the inner wall of the roller under the action of the centrifugal force caused by the high-speed rotation of the roller body in the existing device for correcting the flexible deformation of the rotating roller body. low problem, and provide a device for correcting the flexible deformation of the rotating roller body with a balance device, which can ensure the stability of the fit between the balance bar and the inner wall of the roller, and prevent the effect of centrifugal force from affecting the accuracy of the correction
