Strip hot laminating machine

Abstract

The invention relates to a strip steel hot film laminating machine. The strip steel hot film laminating machine is characterized by comprising a rack, wherein the rack is provided with a water-cooled lining rubber roller and a chrome-plated hot oil roller, the chrome-plated hot oil roller is arranged just above the water-cooled lining rubber roller, a supporting roller and a flattening roller are arranged on one side of the rack, strip steel is supported by the supporting roller and passes through between the chrome-plated hot oil roller and the water-cooled lining rubber roller, and a film is flattened by the flattening roller and laminated on the strip steel by the chrome-plated hot oil roller and the water-cooled lining rubber roller; cold water circulates inside the water-cooled lining rubber roller, hot oil circulates inside the chrome-plated hot oil roller, rotating joints are arranged at two ends of both the water-cooled lining rubber roller and the chrome-plated hot oil roller, and a lifting cylinder is arranged above the chrome-plated hot oil roller. The strip steel hot film laminating machine is good in surface quality of a hot laminated film, and compared with a color coating unit, the strip steel hot film laminating machine is low in cost and little in pollution, can meet the needs of the market, and provides more designs, colors and textures on the strip steel surface.

Description

technical field [0001] The invention relates to the field of strip steel thermal coating, in particular to a strip steel thermal coating machine, which is widely used in strip steel processing lines such as strip steel color coating and coating units. Background technique [0002] In the past, cold-rolled steel strips and galvanized steel strips were used as substrates. After surface pretreatment, the surface of the steel strips was painted to obtain color-coated steel sheets. However, this method has high production costs and heavy pollution. [0003] With the development of thin film technology, especially the development of thermal coating technology, a layer of plastic film can be directly coated on the surface of strip steel to achieve the same surface effect as painting, and can have more surface colors. At the same time, it can produce The cost is greatly reduced and the pollution is reduced. However, the quality of the film of the current laminating machine is poor, ...

Problems solved by technology

[0002] In the past, cold-rolled steel strips and galvanized steel strips were used as substrates. After surface pretreatment, paint was painted on the surface of the strip steel to obtain color-coated steel sheets. However, this method has high production costs and heavy pollution.

[0003] With the development of thin film technology, especially the development of thermal coating technology, a layer of plastic film can be directly coated on the surface of strip steel to achieve the same surface effect as painting, and can have more surface colors. At the same time, it can produce The cost is greatly reduced and the pollution is reduced, but the quality of the current laminating machine is poor and the structure is relatively complicated, which makes the production efficiency low and the production cost high
