Coating machine capable of controlling coating amount of two surfaces and using method thereof

Abstract

The invention relates to a coating machine capable of controlling coating amount of two surfaces. The coating machine comprises a fixed seat, a lower roll 1, an upper roll 1, a limiter 1, an air cylinder 1, a lower roll 2, an upper roll 2, a limiter 2, an air cylinder 2, a lower roll 3, an upper roll 3, a collecting pipe 1, a scratch board, a collecting pipe 2, a carrying device and a touch roll, wherein the top end of the fixed seat is provided with the lower roll 1 and the upper roll 1, and the lower roll 1 is connected with the upper roll 1 through the limiter 1; the top end of the air cylinder 1 is provided with the lower roll 2 and the upper roll 2, and the lower roll 2 is connected with the upper roll 2 through the limiter 2; the top end of the air cylinder 2 is provided with the lower roll 3 and the upper roll 3, and one sides of the lower roll 3 and the upper roll 3 are respectively provided with the collecting pipe 1 and the collecting pipe 2, and the scratch board is arranged at the collecting pipe 1; one end of the carrying device is provided with the touch roll. Compared with the prior art, the coating machine has the beneficial effects of being simple in structure, being scientific and practical, effectively controlling the amount coating of ]the upper surface and the lower surface of belt steel, reducing workload, improving working efficiency, reducing production cost, and creating a high economic benefit for enterprises.

Description

technical field [0001] The invention relates to the technical field of cold-rolled silicon steel, in particular to a coating machine with controllable coating amount on both sides and a use method thereof. Background technique [0002] Coating machines are widely used in the fields of steel, printing and dyeing, etc. According to the structure, they are divided into: three-roll single-track coating machine, three-roll slide rail accumulation coating machine, horizontal three-roll reverse coating machine, simple two-roll coating machine, etc. , the three-roll coating machine can realize the independent adjustment of the coating amount on the upper and lower surfaces, but the equipment volume is large and the investment is high. Although the simple two-roll coating machine has a simple structure and low cost, it is prone to large differences in the coating amount on the upper and lower surfaces. , need unloading roller adjustment. [0003] Invention patent CN200610147268.3, a...
