Abstract

An electrostatic blotting device comprises a transfer printing device and a blotting device, wherein a printing roller (14) of the transfer printing device is in contact with a pressure roll (6) of the blotting device. The utility model has the advantages that the installation is convenient, the use is simple, the blotting device can ensure that no 'white leakage' phenomenon is caused in the gravure printing products, the ink amount of the printed products is even, the density is uniform, the good printing effect can last for a long term, and the working performance is stable; the range of application is extensive, and the device can be applicable to various materials; the production is improved, the service life is prolonged, the processing speed of a gravure printing machine can be improved without affecting the printing quality when the electrostatic blotting device is arranged; and the pressure to an electrostatic embossing roller is reduced, the service life of the electrostatic embossing roller is prolonged, and meanwhile the requirements of better dust-removing effect and the safety can be achieved due to the adsorption effect of the static electricity.

Description

The static blotter

Technical field

The utility model relates to printing technology, a kind of specifically static blotter.

Background technology

In gravure is drawn a design process, because the friction of coiled material and printing ink, make the surface produce certain positive charge or negative electrical charge, because the principle that the same sex is repelled each other, the printing ink adsorption capacity is relatively poor, occurs losing leaking in vain, i.e. " trichobothrium " phenomenon, particularly in some special occasions, not reaching desired printing quality is a very stubborn problem.

The utility model content

The purpose of this utility model is that a kind of transferring rate, elimination ink dot that improves ink dot of design lacks, prints the static blotter of no bright line, raising printing quality.

The utility model static blotter comprises: the printing roller 14 of transfer device and the pressure roll 6 of blotter contact.

Transfer device, comprise: lathe frame 1, screw mandrel 2 is housed on the lathe frame 1, slide bar 3, support 4 and control cabinet 16, motor 5 on 2 one of screw mandrels and the lathe frame 1 one side frame body baffle plates, reductor links to each other, the reverse thread hole that screw mandrel 2 passes two base of the carrier head bottom links to each other with base of the carrier head, chuck 8,9 are contained in respectively on two base of the carrier head, 8 one of chucks and motor 7, reductor links to each other, camera 10 is housed on the slide bar 3, monitor 11 is housed on the support 4, camera 10 links to each other with monitor 11 by lead, prints roller 14 and is contained in chuck 8, between 9, lathe frame 1 can move up and down under the drive of transmission device.

About the transfer device, about, the structure that seesaws is the same substantially with the motion structure of present machine tool dragging plate.

Blotter comprises: frame, pressure roll 6 is housed on the frame, and one on the axle of pressure roll 6 links to each other with motor 17, reductor, and pressure roll 6 is rolled up outward layer of aluminum film 12, and aluminium film 12 links to each other with static discharger 13 by lead.

Have groove on the pressure roll 6, two registration rollers 15 are housed in the groove.

Important technological parameters

1) power input voltage: 220VAC, 50Hz

Electrostatic rod output: static 0～-15kVDC

Static is eliminated rod output: ion 7kV, 50Hz

Power: 100W

2) panel carries function: ion bar, electrostatic rod start-stop control

Scram button

The adjustment of electrostatic rod work range (+,-)

3) environment temperature :-10 ℃～50 ℃

4) air humidity: 0～60%, no steam condenses

The utility model static blotter is achieved in that with static discharger and produces discharge current, electric current forms electric field by thin aluminium conductive layer on the roller platen and ink molecules, thereby make the printing ink electric polarization, move towards the direction of printing material, to obtain better ink printing effect.The static blotting is to utilize a high-purity DC voltage, and by output, passing to volume has the pressure roll top layer of aluminium film, thereby neutralizes unnecessary electric charge, is adsorbed on the coiled material fully to realize forme pit printing ink.

The advantage of the utility model static blotter is: easy for installation, use simply, and guarantee that the gravure goods never produce " leaking white ", the product China ink amount that prints out is even, and density is even, can keep good printing effect, stable work in work for a long time; Applied range can be applicable to various materials, and as thin paper, art post paperboard, art paper, laser paper and reluctant various glued membrane not only can be applied to oil-based ink, also can reach good effect on water color ink; Improve production, life-saving, add the static blotter, can improve the process velocity of intaglio printing press and not influence printing quality, and because the suction-operated of static is arranged, reduced pressure to the static roller platen, improve the service life of static roller platen, reached better dust removing effects and security needs simultaneously.
