Corona processor

Abstract

The invention relates to the film preparation technology field and discloses a corona processor. A machine body is included. A corona device is fixedly installed in a middle portion of a top of the machine body. A corona roller is movably installed below the corona device. A fan is fixedly installed on one side of the top of the machine body. A high-voltage transformer is arranged at a bottom of the machine body. A controller is arranged on a front surface of the machine body, a plurality of conveying rollers for conveying thin films are arranged on two sides of the corona roller, the corona device is provided with an installation block, the bottom of the installation block is connected with a plurality of electrodes through a spring, the corona roller is symmetrically and movably connected with two movable sleeve rings, and the bottoms of the movable sleeve rings are movably connected with moving devices. By using the corona processor, the multiple electrodes are arranged and can be adjusted, redundant ozone and heat are reduced, a utilization rate is increased, a working range can be adjusted according to a specific film, the corona device is tightly attached, an ozone concentration during working can be ensured to be optimal, and a corona effect is good.

Description

technical field [0001] The invention relates to the technical field of film preparation, in particular to a corona treatment machine. Background technique [0002] In the process of film preparation, corona treatment is required to increase the adsorption and viscosity of the film surface, so that the film is easier to adhere to ink, etc. The machine that achieves the corona effect is the corona treatment machine. The principle of the corona treatment machine Yes: use high frequency and high voltage to corona discharge on the surface of the film to be treated, and generate low temperature plasma, make the surface of the film produce free radical reaction and crosslink the polymer, make the surface rough and increase its moisturizing effect on polar solvents. Wetness - These ions penetrate into the surface of the printed body by electric shock and penetrate into the surface to destroy its molecular structure, thereby oxidizing and polarizing the surface molecules to be treate...

AI Technical Summary

Problems solved by technology

[0003] Existing corona treatment machines often use monolithic long strip electrodes. When using this, since the width of the film undergoing corona treatment is not always consistent with the length of the electrode, there will be partial electrodes without corona to the film. Empty electricity, and the discharge of the electrode itself will generate ozone, nitric oxide and other gases, which will cause a large amount of ozone to be generated in areas without thin films, increasing the concentration of ozone, etc. Too much gas will cause pollution to the It is harmful to the human body, and the electrode discharge will also generate a lot of heat, and the part without the film corona will also generate a lot of heat, which will affect the properties of the film and cause the film to deteriorate.

[0004] The width of the film is variable. When a monolithic electrode is used to corona the film, it will cause waste in the area without the film, and the excess heat will cause the corona effect of the film to deteriorate, which is not conducive to the realization of the film. Good corona effect, and a small amount of ozone has an additive effect on the corona of the film, but too much ozone is not conducive to corona, and it needs to be extracted as soon as possible
