The machine comprises a frame and two upper and lower corona units, wherein the corona units comprise a corona roller shell (1) and an electrode. Both ends of the corona roller shell (1) are arranged on the frame, and a supporting rod No. 1 connecting rod (2) parallel to the corona roller shell (1) is arranged on the frame. The electrode is installed on the supporting rod No. 1 connecting rod (2). In a state of use, the plastic film passes between the corona roller shell (1) and the electrode. The corona roller shell (1) and the electrode of the upper corona unit are respectively arranged on the left and right sides of the frame, and the corona roller shell (1) and the electrode of the lower corona unit are respectively located on the right and left sides of the frame, so as to punch concave and convex grooves on the front and back sides of the plastic film.

[0004] However, in the prior art, when the corona machine is working, the electric field excitation will ionize the molecules and atoms in the air, thereby initiating a large number of chemical reactions. When the electric field excitation intensity increases, the number of charged ions generated by the corona also increases, and the water molecules in the air will be decomposed to generate water vapor. In addition, during the corona discharge process, high temperature, high pressure and other conditions will also be generated, which will also promote the decomposition of water molecules and the generation of water vapor. Part of the generated moisture will be extracted with the exhaust equipment, and the other part will directly adhere to the surface of the film. After the film is processed, the concave area will be attached with water vapor, affecting subsequent use. Utility Model Content
