Description

Adjustable film corona waste gas treatment device Technical Field The application relates to the field of film corona, in particular to an adjustable film corona waste gas treatment device. Background In the production process of the plastic film, part of the film needs to be printed with exquisite characters and patterns on the surface of the film, and the corona treatment can ensure that the ink is firmly attached and avoid abrasion and fading in transportation. The corona treatment is carried out by high-voltage discharge, molecular chemical bonds on the surface of the plastic film are broken and degraded by high-energy particle bombardment, the surface of the film which is smooth originally and has strong inertia becomes rough and porous, more anchor points are provided for the adhesion of subsequent printing materials, and the production requirement is met. A large amount of ozone is generated upon corona discharge. On one hand, the strong oxidizing property of ozone can excessively oxidize the surface of the film, so that molecular chains are excessively broken, embrittling and chalking phenomena appear on the surface of the film, and on the other hand, excessive ozone can cause color change on the surface of the film, thereby influencing the appearance quality. Therefore, an exhaust gas treatment device is required to be arranged at the corona position, ozone and other exhaust gases generated by corona are pumped away, and negative influence on the film is avoided. At present, common film corona exhaust treatment device in the market adopts bolt and welded mode fixed mounting in corona emergence position more, lacks adjustment mechanism, can not adjust exhaust treatment device's angle according to actual need, influences exhaust treatment's efficiency. Disclosure of utility model In order to solve the problem that the film corona waste gas treatment device is rigidly fixed in a corona generating region and the angle of the waste gas treatment device cannot be adjusted according to actual needs, the application provides an adjustable film corona waste gas treatment device.
