Abstract
The utility model discloses a kind of corona unit for plastic cement printing material, it comprises: board, be arranged on the Corona roller on board and the electron bombardment machine for corona, the high frequency voltage produced by electron bombardment machine forms corona discharge between Corona roller and corresponding electrode, to carry out sided corona treatment to the plastic printing material surface through Corona roller, be covered with a cover body above described Corona roller, in described cover body, be provided with heater.The utility model adds heater in current supply unit, while corona, thin-film material is heated, thus eliminate the tension force of himself, guarantee that corona rear surface adhesive force can not increase in time and reducing, guarantee follow-up printing effect further.
Description
Technical field:
The utility model relates to printing machine equipment technical field, refers in particular to a kind of corona unit for plastic cement printing material.
Background technology:
The principle of sided corona treatment produces a kind of high voltage electric field environment by electric shock. in such a case, electron stream carries out strong impact to subflow to plastic sheeting can make film surface fluff, and becomes coarse, increases surface area.When adhesive and its surface contact, just can produce good infiltration, in the chase that adhesive can penetrate into by plucking, film secure bond is made by " casting anchor " effect, this is a kind of physical action, the relatively untreated film of film after the process of magnification at high multiple Microscopic observation, its surface is obviously uneven and very coarse, and surge intensity can strengthen along with the rising of voltage and current.Surface roughening and increase its to polar solvent wetting recall-these gas ions are by shocking by electricity and penetrating into by its molecular structure of surface breakdown of print body, and then by the oxidation of processed surface molecular and polarization, ion electric shock erosion surface, so that increase the adhesive ability on stock surface.
See that the patent No. is: the Chinese utility model patent description of 201120381439.5, it discloses a kind of corona unit, this corona unit comprises frame, frame is provided with Corona roller, the below parallel with Corona roller is provided with electrode, in a tubular form and do not contact with Corona roller, Corona roller and electrode are connected with efficient film electron bombardment machine the two poles of the earth described electrode respectively.Its beneficial effect is: because the below parallel with Corona roller is provided with electrode, described electrode in a tubular form and do not contact with Corona roller, Corona roller and electrode are connected with efficient film electron bombardment machine the two poles of the earth respectively, so high-voltage arc can be produced between Corona roller and electrode, the Surface Polarization by the metal between Corona roller and electrode and plastic plate can be made, thus change the adhesive ability of its material surface.Meanwhile, during owing to printing on a plastic film, drive constantly closely giving of film by continuous rotation of Corona roller, greatly can improve the efficiency of corona.If but excessive velocities, corona effects is bad, and this is the treatment effect needing to improve by increasing current strength corona.But be through experiment, if after the intensity of electric current reaches certain numerical value, along with the increase of current strength, the surperficial heavy damage that plastic sheeting is final, affects last printing effect.In addition, the plastic sheeting after sided corona treatment, through after a period of time, its surface adhesion force can decline, this is because the recovery of Plastic film surface tension force, this is also by printing effect final for impact.
The present inventor, through constantly research, proposes following solution, to overcome the problems referred to above.
Utility model content:
Technical problem to be solved in the utility model is just the deficiency overcome existing for existing product, a kind of corona unit for plastic cement printing material is provided, keep stable by its surface adhesion force of plastic cement printing material after the utility model corona, guarantee the effect of printing.
In order to solve the problems of the technologies described above, the utility model have employed following technical proposals: the corona unit for plastic cement printing material comprises: board, be arranged on the Corona roller on board and the electron bombardment machine for corona, the high frequency voltage produced by electron bombardment machine forms corona discharge between Corona roller and corresponding electrode, to carry out sided corona treatment to the plastic printing material surface through Corona roller, be covered with a cover body above described Corona roller, in described cover body, be provided with heater.
Furthermore, in technique scheme, described heater comprises: along the equally distributed electric heating tube of Corona roller cambered surface.
Furthermore, in technique scheme, described cover body is provided with an exhaust column.
Furthermore, in technique scheme, the both sides of described Corona roller are respectively arranged with the pinch roller be mated.
Furthermore, in technique scheme, the both sides of described Corona roller are respectively used to the transfer roller of plastic printing material conveying.
The utility model adds heater in current supply unit, to eliminate the tension force of plastic printing material self.Each quasi-polyethylene (PE) etc. has the material of nonpolar molecule, its surface is difficult to the ink molecules of adhering to polarity, after the utility model corona, make its superficial layer forming polarity to improve the binding strength with polarity ink, meanwhile, because the utility model adds heater, while corona, thin-film material is heated, thus eliminate the tension force of himself, guarantee that corona rear surface adhesive force can not increase in time and reducing, guarantee follow-up printing effect further.
Accompanying drawing illustrates:
Fig. 1 is the utility model perspective view;
Fig. 2 is the utility model structural representation.
Detailed description of the invention:
Below in conjunction with specific embodiments and the drawings, the utility model is further illustrated.
See shown in Fig. 1,2,1, for the corona unit of plastic cement printing material, comprise: board 1, be arranged on the Corona roller 2 on board 1 and the electron bombardment machine 10 for corona, the high frequency voltage produced by electron bombardment machine 10 forms corona discharge between Corona roller 2 and corresponding electrode, to carry out sided corona treatment to plastic printing material 8 surface through Corona roller 2
Be covered with a cover body 3 above described Corona roller 2, in described cover body 3, be provided with heater 4.On cover body 3, also this only has electric source connecting box 100, to be connected by wire with electron bombardment machine 10.An exhaust column 5 is provided with, by equipment such as external air blast or fans to carrying out exhausting operation in cover body 3, to fall heat unnecessary in cover body 3 and the thermogenetic smell discharge of Yin Jia above cover body 3.
Heater 4 is made up of multiple heating tube 41, and these heating tubes 41 are uniformly distributed according to Corona roller 2 cambered surface, to realize the homogeneous heating to plastic printing material 8.
In addition, in order to make plastic printing material 8 fit tightly in Corona roller 2, be respectively arranged with the pinch roller 6 be mated in the both sides of Corona roller, this pinch roller adopts the rubber tire of insulation.Meanwhile, the both sides of described Corona roller 2 are respectively used to the transfer roller 7 of plastic printing material 8 conveying.
Certainly, the foregoing is only specific embodiment of the utility model, be not limit the utility model practical range, all equivalences done according to structure, feature and principle described in the utility model claim change or modify, and all should be included in the utility model claim.
