Gradation roller coating device of aluminum plate

Abstract

The invention provides a gradation roller coating device of an aluminum plate. The gradation roller coating device comprises a material conveying conveyer belt device, a primary roller coating device, a first drying air box, a secondary roller coating device, a second drying air box and a material discharging conveyer belt device, wherein the output end of the material conveying conveyer belt device is provided with the primary roller coating device; a material charging coating roller mechanism, a transition coating roller mechanism, a roller coating roller mechanism and a scraper device are arranged in the primary roller coating device; the first drying air box is arranged between the primary roller coating device and the second roller coating device; an air blower is arranged below the first drying air box; a plurality of heating pipes are arranged above the first drying air box; a second drying air box is arranged between the secondary roller coating device and the material discharging conveying device; material feeding is realized for the roller coating roller mechanism through the transition coating roller mechanism, so that paint with uniform thickness can be smeared on the surface of the roller coating roller; roller coating is performed in a grading manner using the two roller coating devices; besides, drying is separately performed after roller coating; uniform roller coating of the aluminum plate is ensured; and production efficiency is improved.

Description

【Technical field】 [0001] The invention relates to the technical field of aluminum plate production, in particular to an aluminum plate graded roll coating device. 【Background technique】 [0002] In the field of aluminum sheet and strip processing, roll coating is required on the surface of the aluminum sheet to protect the surface quality of the aluminum sheet and improve the aesthetics. The existing aluminum plate roll coating uses a roll coating roller to directly carry out the roll coating of the aluminum plate, and the liquid carrying rate of the roll coating roll is difficult to control, resulting in uneven roll coating of the aluminum plate. Therefore, a rolling coating device for aluminum plates is proposed. 【Content of invention】 [0003] The purpose of the present invention is to solve the problems in the prior art, and propose a rolling coating device for aluminum sheets in stages, which can make the surface of the rolling coating roller covered with a uniform th...
