Hot air drier having a variance nozzle

Abstract

The invention relates to a hot air drier having a variance nozzle. The hot air drier includes: a drying oven, coated with a film coating solution to a predetermined thickness in one direction through the drying oven; an inner chamber disposed within an interior space of the drying furnace, and is filled by hot air supplied from the outside; a first nozzle , which is detachably assembled within the interior chamber, so that the first inlet is formed in the through the internal chamber of the plurality of hot air supply ports communicating; a second nozzle, having a second inlet in order to be able to move inserted in a manner corresponding to the first nozzle extends a predetermined length from the first discharge port, and communicates with the first nozzle to the outlet through the second coated with the coating solution to the film side injection of hot air; and a nozzle adjusting portion, a second nozzle disposed in a first adjustment screw, a first adjustment screw, disposed in the through hole formed in a first regulating nozzle of the first, with respect to the first nozzle portion to change the position of the second nozzle nozzle adjustment to adjust the interval between the second nozzle and the film.

Description

technical field [0001] The present invention relates to a drying machine for drying a coating liquid coated on a coating film by hot air, and more specifically, relates to a method capable of preventing vibration of the coating film generated during the time when the coating film passes through the inside of the drying furnace in one direction. It is a hot air dryer with a variable discharge nozzle that can change the position and discharge amount of the discharge port of the nozzle relative to the film. When the nozzle becomes old, it can be easily separated from the chamber and replaced. Background technique [0002] Usually, the coating film hot air dryer cures the coating liquid by drying the coating liquid with a predetermined thickness on the surface of the film by hot air. [0003] This type of dryer is installed on the outlet side of the coating equipment, and the nozzles are arranged so that the hot air flowing into the interior through the duct faces the film, and ...

Problems solved by technology

[0007] However, in such a conventional coating film drying machine, the nozzle for spraying hot air for drying the coating liquid applied to the film is integrally provided in the above-mentioned distribution chamber, so it is difficult The problem of changing the nozzles of various forms according to the conditions of the coating liquid for drying the coating film of the object or the speed of the coating film

[0008] And, since the above-mentioned nozzle is provided in the distributing chamber in an integrated manner, the vertical interval between the coating film as the drying object and the discharge end of the nozzle cannot be adjusted, and thus the coating liquid applied to the coating film cannot be adjusted. Depending on the drying conditions of the coating film or the change of the passing speed of the coating film, the discharge end of the nozzle is brought close to the film or separated from the film and the spraying conditions are changed, thereby limiting the improvement of the drying efficiency of the coating liquid.

[0009] In particular, during the drying of the coating liquid while the coating film passes through the inside of the drying furnace, in order to prevent the hot air sprayed from the discharge end of the nozzle from colliding with the coating film, Shaking phenomenon requires the staff to adjust up and down between the discharge end of the nozzle and the surface of the coating film according to the drying conditions, but it is impossible to adjust up and down in the existing nozzle structure, so it is difficult to prevent the shaking phenomenon caused by the coating film Defective products caused by
