[0002] The principle of corona treatment is to improve the coating adhesion of plastic films by using electrostatic discharge, resolving adhesion issues associated with printing on polypropylene and polyethylene films. Furthermore, surface moisture and high-solids radiation-curable inks increase the surface energy of films such as polyvinyl chloride and polyester.

[0004] However, the above device still has certain defects. For example, when the existing film corona treatment machine is used, a large amount of gas generated by the film corona remains inside the processing box. When the worker opens the processing box, the gas generated by the corona can easily cause harm to the worker's body.

[0005] Therefore, it is necessary to invent a capacitor film corona treatment device with adjustable electrode angle to solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to provide a capacitor film corona treatment device with adjustable electrode angle, which realizes effective adsorption or oxidation absorption of ozone generated in the corona treatment through the linkage between the exhaust fan, the folding tube, the gas gathering tank, the exhaust pipe, the water tank and the air filter element, so as to avoid the effect of such harmful gases being directly discharged and absorbed by the human body, so as to solve the problem in the prior art that when a large amount of gas generated by the film corona remains inside the processing box, the gas generated by the corona is likely to cause harm to the worker's body when the worker opens the processing box.

[0007] Material toggling mechanism, its both sides respectively have a cylinder pressure, and the cylinder pressure bar connects swing arm, and the swing arm end face has hook portion, and a bar passes position between the end of two swing arms and the hook portion.

[0008] Preferably, the left side of the top of the water tank is connected with a vertical pipe, the inner side of the vertical pipe is connected with a sleeve, and the inner side of the sleeve is bolted with an air filter element, so that the gas discharged from the water tank will be filtered by the air filter element in the sleeve and then discharged.

[0009] Preferably, a corona treater is bolted to the top of the connecting plate, and both sides of the front side of the inner cavity of the frame are rotatably connected to corona treater rollers via bearings.

[0010] Preferably, the upper and lower sides of the right side of the front side of the mounting plate are rotatably connected to drive rollers through bearings, the back side of the drive roller is bolted with an extension rod passing through the mounting plate, and the surface of the extension rod is bolted with a linkage gear, so that the linkage gear can drive the drive roller to rotate in opposite directions through the extension rod.

[0011] Preferably, a servo motor is bolted to the right side of the top of the base plate, and a synchronous sprocket is bolted to the output end of the servo motor and the surface of the extension rod. A chain is engaged with the surface of the synchronous sprocket, so that the servo motor serves as a driving source and drives the driving roller to rotate through the synchronous sprocket and the chain.

[0012] Preferably, both sides of the mounting plate are rotatably connected to tension rollers through bearings, so that the tension rollers can ensure that the capacitor film has sufficient surface tension during the mobile corona treatment process, avoiding wrinkles on the film surface due to insufficient tension, which affects the continuity of the corona treatment.

[0013] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0014] 1. The stepper motor drives the screw to rotate, and the distance between the corona treater on the top of the connecting plate and the corona treatment roller is controlled to achieve the effect of effective corona treatment on films of different sizes. At the same time, turning off or on the corona treater on the corresponding side can facilitate the user to perform corona treatment on a specific side of the film, thereby improving the flexibility of the device.

[0015] 2. Through the linkage between the exhaust fan, folding tube, gas collection tank, exhaust pipe, water tank and air filter, the ozone generated in the corona treatment can be effectively adsorbed or oxidized and absorbed, avoiding the direct discharge of such harmful gases and their absorption by the human body, which would cause irreversible physical damage to the workers.

[0025] like Figure 1 and Figure 2 As shown, a vertical pipe 15 is connected to the left side of the top of the water tank 12, a sleeve 16 is inserted into the inner side of the vertical pipe 15, and an air filter element 17 is arranged and bolted on the inner side of the sleeve 16, so that the gas discharged from the water tank 12 will be filtered by the air filter element 17 in the sleeve 16 and then discharged.

[0026] like Figure 1 and Figure 4 As shown, a corona treater 18 is bolted to the top of the connecting plate 6 , and corona treater rollers 19 are rotatably connected to both sides of the front side of the inner cavity of the frame 3 through bearings.

[0027] like Figure 1 and Figure 2 As shown, the upper and lower sides of the right side of the front side of the mounting plate 2 are rotatably connected to the driving rollers 20 through bearings, and the back side of the driving roller 20 is bolted with an extension rod 21 passing through the mounting plate 2, and the surface of the extension rod 21 is bolted with a linkage gear 22, so that the linkage gear 22 can drive the driving rollers 20 to rotate in opposite directions through the extension rod 21.

[0028] like Figure 1 and Figure 2 As shown, a servo motor 23 is bolted to the right side of the top of the base plate 1, and a synchronous sprocket 24 is bolted to the output end of the servo motor 23 and the surface of the extension rod 21. A chain 25 is engaged with the surface of the synchronous sprocket 24, so that the servo motor 23 serves as a driving source and drives the driving roller 20 to rotate through the synchronous sprocket 24 and the chain 25.

[0029] like Figure 1As shown, both sides of the mounting plate 2 are rotatably connected to tensioning rollers 26 through bearings, so that the tensioning rollers 26 can ensure that the capacitor film has sufficient surface tension during the mobile corona treatment process, thereby avoiding wrinkles on the film surface due to insufficient tension, which affects the continuity of the corona treatment.

At this time, the treatment liquid in the water tank 12 is generally an alkaline solution such as nitric acid solution, which covers the bottom of the folding tube 14, so that the harmful substances in the gas entering the water tank 12 are adsorbed or oxidized by the treatment liquid at the first time. The remaining gas will be filtered twice by the air filter element 17 and finally discharged to prevent the human body from directly absorbing such gas.
