Single-roller coating machine

Abstract

The invention relates to a single-roller coating machine. The single-roller coating machine comprises a rack, an upper coating roller, a lower coating roller, an upper roller frame, an upper lifting mechanism, a lower roller frame and a lower lifting mechanism, wherein the rack is fixedly installed on a workshop platform, the section, perpendicular to the strip steel running direction, of the rackis in an n shape or a rectangular shape, a bearing seat of the upper coating roller and a bearing seat of the lower coating roller are arranged on the roller frames in a sliding manner correspondingly, the sliding direction is parallel to the axial direction of coating roller bodies, a transmission side frame body and / or an operation side frame body of the rack are / is provided with roller replacing channels allowing the upper coating roller and the lower coating roller to pass through. The rack is fixedly mounted on the workshop platform, and the n-shaped or rectangular section is adopted, sothat the structural rigidity and stability of the whole equipment are guaranteed, and the uniformity of a coating can be improved; and the upper coating roller and the lower coating roller are designed to be installed on the corresponding roller frames in a sliding mode, other components do not need to be moved in the roller replacing operation process, operation is convenient and fast, time andlabor are saved, maintenance efficiency can be remarkably improved, and maintenance cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of metallurgical equipment, and in particular relates to a single-roll coating machine. Background technique [0002] At present, in the production of silicon steel, a single-roll coating machine is generally used to coat magnesium oxide coating liquid and a low-viscosity insulating layer coating liquid on silicon steel. The structure of the single-roll coating machine is basically spraying and extrusion, that is, There is a non-transmission coating roller on the upper and lower sides of the steel. These two coating rollers are grooved rollers. Excessive coating liquid is sprayed at the entrance of the upper coating roller, lower coating roller and strip steel. The film thickness of the coating is adjusted by the mutual pressing force between the roller and the lower coating roller. [0003] At present, the C-frame type single-roll coating machine is more widely used. The frame is a "C"-shaped frame and a m...

Problems solved by technology

This roll change process has many moving parts and takes a long time to change rolls, which has a certain impact on the production rhythm and cost. At the same time, the coating liquid will be spilled around the coating machine, causing certain environmental pollution; moreover, in order to enter and exit the belt The rigidity of the opening of the "C" frame designed with steel is poor, which indirectly affects the rigidity of the coating roller and affects the uniformity of the coating on the operation side and the transmission side, and the movement of the "C" frame is also difficult. It will indirectly affect the installation and positioning accuracy of the upper coating roller and the lower coating roller, and affect the accuracy of the coating thickness
