Description

Technical Field

[0001] The utility model relates to the technical field of corona machines, in particular to a sheet corona machine. Background Art

[0002] Corona machines are commonly used for surface corona treatment of slit single sheets of silicone rubber, plastic, glass panels, etc., in order to improve printing, gluing and lamination fastness. The basic principle of the corona treatment machine is to apply a high-frequency, high-voltage power supply between the discharge electrode and the corona treatment roller. When the voltage exceeds the ionization resistance of the air gap of 1 mm to 2 mm, continuous discharge will be generated, causing the air to ionize and produce various plasmas and form a large amount of ozone. The generated plasma and ozone are used to treat the surface of the sheet.

[0003] When the corona machine is in use, the material to be coronaed needs to be placed on a conveyor belt, and the conveyor belt is used to drive the material under the electrode roller to complete the corona process of the material.

[0004] Most of the existing corona machines use an integrated electrode roller (corona roller), and the electrode roller is installed under the conveyor belt (such as a plate-type corona machine with a cleaning function disclosed in application number 2021223380513). When the electrode roller is damaged or needs to be cleaned, it is extremely inconvenient to replace or clean the electrode roller, and the entire electrode roller needs to be replaced, which has a high cost of use.
