Abstract

The utility model discloses a film double faced corona processing device, including a corona discharge rack and a high frequency transformer; the high frequency transformer is located on one side of the corona discharge rack; the corona discharge rack includes a support, and a pair of passing rollers, two discharge electrodes, two silica gel guide rollers and more than one traction roller which are installed on the support; two passing rollers are juxtaposed on an input end of the support; two silica gel guide rollers are arranged on an output end of the film; the film is introduced from two passing rollers, passes through the traction roller coils about two silica gel guide rollers in an S shape and exits; two discharge electrodes are respectively pressed against two silica gel guide rollers with respect to the film; the distance between each discharge electrode and corresponding silica gel guide roller is 0.5-1cm; and the high frequency transformer is electrically connected with two discharge electrodes. The utility model utilizes electrical spark generated on the surface of the discharge electrodes to perform corona treatment on double faces of the film, is simple in construction and convenient in operation; and the film after corona treatment has an improved viscosity so as to be directly adhered with paper.

Description

The two-sided corona treatment plant of a kind of film

Technical field

The utility model relates to a kind of corona treatment plant, particularly relates to the two-sided corona treatment plant of film.

Background technology

Because of adding auxiliary agent, the surface has wax etc. to ooze out, and particularly adopts the film surface that blows pulling shaping smooth, is difficult for adsorbing mutually with printing-ink, coating material, paper and adhesive, is difficult for printing on its surface or amplexiforming in the production of plastic film.

At this present situation, often film surface is adopted sided corona treatment at present, the principle of sided corona treatment is surge or puncture, under the high voltage electric field effect, electron stream carries out strong impact to film class non-absorbent material can make its wildness, thereby makes the surface become coarse, increases surface area.

When the film of sided corona treatment was pasted mutually with paper, adhesiveness did not often reach requirement at present, needed to add between film and paper coating one deck adhesive.Simultaneously, present sided corona treatment operational sequence is more loaded down with trivial details, the equipment complexity, and production cost is higher.

Summary of the invention

The utility model provides a kind of equipment simple in order to overcome the deficiency of above-mentioned prior art, the two-sided corona treatment plant of easy to operate film.

In order to achieve the above object, the two-sided corona treatment plant of the utility model film comprises corona discharge frame and high frequency transformer, described high frequency transformer is positioned at corona discharge frame one side, described corona discharge frame comprises support, and rack-mount a pair of roller, two discharge electrodes, two silica gel deflector rolls, above carry-over pinch rolls crossed; Described two inputs of crossing roller and placing support, two silica gel deflector rolls are located at the film output, film is crossed between the roller from two and is imported, through behind the carry-over pinch rolls, S shape is exported behind two silica gel deflector rolls around the home, two corresponding respectively films of discharge electrode are close to two silica gel deflector roll places installations, and the distance between each discharge electrode and corresponding silica gel deflector roll is 0.5-1cm, and high frequency transformer is electrically connected with two discharge electrodes.

Described discharge electrode two ends can be regulated and be installed on the support, and support is provided with the flute profile fixing hole of two discharge electrodes, the discharge electrode two ends by bolting in the flute profile fixing hole.

Cross the tension force that roller and two carry-over pinch rolls can be adjusted film for two, film is moved stably, can also adjust film position on the silica gel deflector roll.

In a word, adopt structure of the present utility model, the electric spark that utilizes the generation of discharge electrode surface is to the two-sided sided corona treatment of carrying out of film, equipment is simple, easy to operate, and can directly paste mutually with paper through the film of sided corona treatment, can be omitted in the operation of adhesive coating on the film.

Description of drawings

Now in conjunction with the accompanying drawings the utility model is further elaborated:

Fig. 1 is the structural representation of the two-sided corona treatment plant of the utility model film;

Fig. 2 is the fixing structure enlarged drawing in discharge electrode two ends of the two-sided corona treatment plant of the utility model film.

The specific embodiment

As Fig. 1 or shown in Figure 2, the two-sided corona treatment plant of the utility model film comprises corona discharge frame 1 and high frequency transformer 2, described high frequency transformer 2 is positioned at corona discharge frame 1 one sides, described corona discharge frame 1 comprises support 11, and be installed in a pair of on the support 11 and cross roller 12, two 15,16 and above carry-over pinch rolls 17 of 13,14, two silica gel deflector rolls of discharge electrode; Described two inputs of crossing roller 12 and placing support 11, two silica

gel deflector rolls

15,16 are located at the film output, film is crossed between the roller 12 from two and is imported, through behind the carry-over pinch rolls 17, S shape is two silica

gel deflector roll

15,16 back outputs around the home, two

discharge electrode

13,14 corresponding respectively films are close to the installation of two silica gel deflector rolls, 15,16 places, and the distance that each

discharge electrode

13,14 and corresponding silica gel deflector roll are 15,16 is 0.5-1cm, and high frequency transformer 2 is electrically connected with two

discharge electrodes

13,14.

Described

discharge electrode

13,14 two ends can be regulated and be installed on the support 11, and support 11 is provided with the flute profile fixing hole 111 of two

discharge electrodes

13,14, and

discharge electrode

13,14 two ends are fixed in the flute profile fixing hole 111 by bolt 3.This bolt 3 can be regulated the distance of 15,16 of

discharge electrode

13,14 and silica gel deflector rolls, so that better carry out the corona operation.

After connecting power supply, discharge electrode 13, the 14 transferring high voltage electric currents in 2 pairs of corona discharge framves 1 of high frequency transformer,

discharge electrode

13,14 surfaces form the some spark.

When using operation, film is crossed between roller 12 from two earlier and is imported, and enters carry-over pinch rolls 17 again, and carry-over pinch rolls 17 are adjusted the tension force of films, and film is moved stably, can also adjust the position of film on silica

gel deflector roll

15,16; Through behind the carry-over pinch rolls 17, film passes from

first discharge electrode
