Abstract
The utility model provides a corona machine which comprises a corona box, an electrode sheet and a corona roller, wherein the electrode sheet and the corona roller are oppositely arranged in the corona box; the length of the electrode sheet is less than that of the corona roller. The corona machine provided by the utility model can be used for improving the electrode sheet in the corona box, so that the length of the electrode plate is less than that of the corona roller; during the discharge process of the electrode sheet; the membrane regions of the electrode sheet and the corona roller discharge electricity; the electricity discharge corona phenomenon of the membrane-free regions between the electrode and the corona roller is relieved for the shortening of the electrode sheet; further the corona current intensity is lowered further; further the breakdown probability of the corona roller is lowered; and the service life of the corona machine is prolonged.
Description
Technical field
The utility model relates to printing technology, relates in particular to a kind of corona machine.
Background technology
Corona treatment is commonly called as corona machine, the mechanical, electrical spark machine of electron bombardment at packaging industry.Be called as dielectric barrier discharge academicly.Be mainly used in the surface treatment of plastic sheeting class or plastic plate based article, before will carrying out ink printing, compound, blown film, coating, gluing, material modification, grafting, polymerization, plated film, curtain coating, stickup processing to above-mentioned material, for the surface that makes product has stronger adhesion, prevent that raw material from occurring printing in process of production and getting rid of look, compound solid, the coating of being pasted not strongly and leak phenomenons such as glue is inhomogeneous.
Please refer to accompanying drawing 1, by discharge, film still can have been caused film corona zone film heat seal strength low by corona (printing color of corona strengthening membrane) between electrode slice 01 in the corona case 03 and the corona roller 02, no film corona zone corona roller 02 is breakdown, and then influences the life-span of corona machine.
Therefore, how solving existing corona machine film is carried out corona roller easy breakdown problem in no film corona zone in the corona process, is present those skilled in the art's problem demanding prompt solution.
The utility model content
In view of this, the purpose of this utility model is to provide a kind of corona machine, to solve in existing corona machine carries out corona to film the process no film corona zone corona roller breakdown problem easily, the life-span of having improved corona machine.
In order to achieve the above object, the technical scheme that provides of the utility model is as follows:
Corona machine comprises the corona case and is arranged in the described corona case, and is oppositely arranged electrode slice and the corona roller that carries out corona discharge, and the length of described electrode slice is less than the length of described corona roller.
Preferably, in the above-mentioned corona machine, described electrode slice and corona roller be arranged in parallel, and the mid point line of both length is parallel with the traffic direction of film.
Preferably, in the above-mentioned corona machine, the two ends of described electrode slice are provided with the step surface towards described corona roller.
Preferably, in the above-mentioned corona machine, the length of described electrode slice is 50cm, and the length of described corona roller is 90cm.
The corona machine that the utility model provides improves the electrode slice in the corona case, make the length of electrode slice less than the length of corona roller, in the process of electrode slice discharge, the diaphragm area that has of electrode slice and corona roller discharges, no diaphragm area since electrode slice shorten cause and the corona roller between the discharge corona phenomenon alleviate, and then reduced corona current intensity, and then reduced the breakdown probability of corona roller, the life-span of having improved corona machine.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below, apparently, accompanying drawing in describing below is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the structural representation of existing corona machine;
The structural representation of the corona machine that Fig. 2 provides for the utility model embodiment.
The specific embodiment
For the purpose, technical scheme and the advantage that make the utility model embodiment clearer, below in conjunction with the accompanying drawing among the utility model embodiment, technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
Please refer to accompanying drawing 2, the corona machine that the utility model embodiment provides comprises corona case 13, electrode slice 11 and corona roller 12, wherein:
Corona case 13 is that the place takes place the corona of corona machine, the place of exoelectrical reaction is provided for electrode slice 11 and corona roller 12, electrode slice 11 and corona roller 12 are arranged in the corona case 13, corona roller 12 and electrode slice 11 are oppositely arranged film are carried out Corona discharge Treatment, the length of electrode slice 11 is less than the length of corona roller 12, width greater than film all carries out sided corona treatment with assurance to film printing position, in the process of work, the film that has only between electrode slice 11 and the corona roller 12 prints the position by corona, flanging does not print the position and does not carry out corona, guarantees that flanging place heat sealability is good.Because the shortening of electrode slice 11 causes and corona roller 12 between electric discharge phenomena alleviate, corona current intensity reduces, and then has reduced the breakdown probability of corona roller, the life-span of having improved corona machine.Simultaneously, above-mentioned corona machine guarantees film printing position by corona, and flanging place film heat seal strength improves, and detects through the laboratory, has improved 4N/15mm.
Concrete, electrode slice 11 and the corona roller 12 of above-mentioned corona machine be arranged in parallel, and the mid point line of both length is parallel with the traffic direction of film.
The electrode slice 11 of above-mentioned corona machine foreshortens to 50cm, the length of corona roller 12 is 90cm, please refer to accompanying drawing 2, the two ends of electrode slice 11 are provided with the step surface towards described corona roller 12, its effect further reduces corona current, can make 20A corona current intensity be down to 10A by 20A, reduce the breakdown probability of corona roller.
To the above-mentioned explanation of the disclosed embodiments, make this area professional and technical personnel can realize or use the utility model.Multiple modification to these embodiment will be apparent concerning those skilled in the art, and defined General Principle can realize under the situation that does not break away from spirit or scope of the present utility model in other embodiments herein.Therefore, the utility model will can not be restricted to these embodiment shown in this article, but will meet the wideest scope consistent with principle disclosed herein and features of novelty.
