Problems solved by technology

Generally speaking, the thickness of the coating film is very thin, which can reach several microns, so that the horizontality of the upper and lower coating rollers, the parallelism of the upper and lower coating rollers, the verticality of the axis of the upper and lower coating rollers relative to the center line of the unit, etc. The precision requirements are very high. If these precision adjustments are not good, the thickness and quality of the coating film will be significantly affected.
In addition, for the two-roll coating machine, when the strip steel drives the upper and lower coating rolls to rotate, the coating rolls will have a horizontal force, and this horizontal force will make the coating rolls tend to move, and after long-term operation, it is easy to use The supporting parts of the coating roller are deformed, which will affect the accuracy of the coating roller and affect the quality of the coating
The existing coating machines basically rely on manual positioning, which not only has low installation and maintenance efficiency, but also is difficult to reliably ensure the accuracy of the upper and lower coating rollers and effectively eliminate the influence of horizontal force on coating quality

Abstract

The invention relates to a two-roller coating machine using tapered wedge adjustment. The two-roller coating machine comprises an upper roller levelness regulation mechanism and a lower roller positioning mechanism. The upper roller levelness regulation mechanism comprises a reference positioning base, a positioning table and an upper tapered wedge adjustment mechanism. The reference positioning base is arranged on a machine frame and comprises a reference positioning face. The positioning table is arranged on an upper roller frame and comprises a horizontal positioning face. The upper taperedwedge adjustment mechanism is used for driving the horizontal positioning face to abut against the reference positioning face. The lower roller positioning structure can horizontally push a lower roller frame in the length direction of the center line of a unit, can lock the lower roller frame and comprises at least one lower tapered wedge adjustment block arranged on a lower roller frame and atleast one lower tapered wedge drive unit arranged on the machine frame. By means of tapered wedge mechanisms, horizontal positioning and regulating of an upper coating roller and a lower coating lowerare achieved; and by locking the upper roller frame and the lower roller frame on the machine frame, the horizontal force borne by the coating rollers during work can be transmitted to the machine frame, precision of the coating rollers is ensured, and the coating quality is improved.

Description

technical field [0001] The invention belongs to the technical field of metallurgical equipment, and in particular relates to a two-roll coating machine adjusted by a wedge. Background technique [0002] At present, in the production of silicon steel, how to apply the silicon steel coating solution evenly on the upper and lower surfaces of the strip steel, and then dry it to form a uniform and stable coating on the surface of the strip steel is the key to obtaining good product quality. one of the key factors. At present, for the coating equipment of silicon steel, the two-roller coating machine has certain achievements. The two rolls are non-driven, and the film thickness of the coating can be adjusted online by adjusting the working pressure of the upper and lower coating rolls. . Generally speaking, the thickness of the coating film is very thin, which can reach several microns, so that the horizontality of the upper and lower coating rollers, the parallelism of the uppe...
