Wet film manufacturing device capable of protecting base material

Abstract

The invention relates to a wet film manufacturing device, in particular to a wet film manufacturing device capable of protecting a base material. The wet film manufacturing device comprises a base, a coating roll fixed to the lower end face of the base and used for coating paint and two side plates arranged on the left side face and the right side face of the coating roll respectively. The side plates are connected with the lower end face of the base. The bottoms of the cross sections of the side plates and the coating roll are semicircular. The radius of the cross section of the coating roll is smaller than that of the cross sections of the two side plates. The height difference value of the lowest end of the coating roll and the lowest end of the cross section of each side plate ranges from 100 micrometers to 1000 micrometers. The thickness of a finally-manufactured wet film is decided through the difference value of the radius of the cross section of the coating roll and the radius of the side plates, and the difference value can be set according to the thickness of the required wet film and can be designed to be 100 micrometers or 150 micrometers or 500 micrometers or 1000 micrometers. By the adoption of the wet film manufacturing device, the surface of the base material is not likely to be scratched and is evenly coated.

Description

technical field [0001] The invention relates to a wet film preparation device, in particular to a wet film preparation device capable of protecting substrates. Background technique [0002] As we all know, in the field of coatings, researchers often need to measure basic parameters such as hiding power and color of coating samples or make coating samples. This just needs research to prepare the wet film that has specific thickness with the coating of researching, because the instability of people's arm, thereby the wet film that is produced by manual coating usually varies in thickness and is difficult to reach the requirement of test, so the skilled in the art Personnel usually rely on the help of wet film preparers to prepare wet films of relatively uniform thickness. [0003] However, the existing wet film preparation devices usually have edges and corners, so the edges and corners of the existing wet film preparation devices are easy to scratch the substrate during the ...

Problems solved by technology

[0003] However, the existing wet film preparation devices usually have edges and corners, so the edges and corners of the existing wet film preparation devices are easy to scratch the substrate during the coating process, especially when coating materials like polyester film materials, the surface It is easy to be scratched, which leads to the problem of difficult coating and uneven coating
