AI Technical Summary

Technical Problem

In the prior art, the use of air knives with a large air output volume leads to excessive wind speed, which will impact the slurry on the surface of the substrate and affect the crystallization quality of the coating film.

Method used

A wind knife device is designed, including a first plate body, a second plate body and a wind knife gasket sandwiched between them, forming a wind discharge slit, and a flared structure is provided at the outlet to reduce wind speed and increase air discharge volume.

Benefits of technology

By reducing the wind speed and reducing the impact on the slurry on the substrate surface, the crystallization quality of the coating film is ensured, and the air output is increased, the crystallization time is shortened, and the production efficiency is improved.

Abstract

The utility model provides an air knife device, which belongs to the technical field of flat plate coating and comprises a first plate body, a second plate body and an air knife gasket clamped between the first plate body and the second plate body, an air outlet slit is defined by the first plate body, the air knife gasket and the second plate body, and the air outlet slit is arranged in the air outlet slit. An outlet of the air outlet slit is arranged to be in a flaring shape. According to the air knife device provided by the utility model, under the condition that the input air quantity of the air knife is not changed, the flaring-shaped structure is arranged, so that the air passing area is gradually increased, and the air speed of an air knife outlet is reduced, thereby reducing the impact effect on slurry on the surface of a base plate, ensuring the crystallization quality of a coating film on the surface of the base material, and meanwhile, improving the production efficiency. Under the condition that the air speed is kept unchanged, the area of an outlet is increased, the air outlet amount is increased, the crystallization speed of a coating film on the surface of a base material can be shortened, and the production efficiency is improved; by arranging the flaring with different angles, the size of the air outlet of the air knife can be changed.
