Description

Water color ink printing heating guide roll device

Technical field

The utility model relates to printing equipment accessory, particularly relates to water color ink printing heating guide roll device.

Background technology

We produce printing food, drug packing material at present, use traditional printing-ink based on solvent type ink, mainly chlorinated polypropylene ink, are solvent, account for 50% of gravure ink composition with toluene; Water-based inks then cannot ensure complete baking and curing in this technique, equipment situation.Not only solvent-based ink, mainly chlorinated polypropylene ink, be solvent with toluene, account for 50% of ink ingredient, poisonous but also produce fuel gas, and benzene is very big to harm, has penetrating odor.Although such ink is used in food, drug packing material aspect country does not forbid, but in line with long-term goal, take the lead in studying alone the use of water-based inks, intaglio printing water color ink adopts water-borne acrylic resin emulsion, water, aqueous pigment and novel water-soluble additive composition, its defect is to there is the features such as penetrating odor, color are not bright-coloured, corrosion galley, the rear poor adhesive force of print, and especially the tool of the relatively multipair food of residual solvent, drug packing material quality has a certain impact.Production environment can not get ensureing, does not reach environmental requirement, and organic volatile is comparatively large to the discharge capacity in air, contaminated environment.Because solvent-based ink in press volatilizees faster than water-based inks volatilization, so on former solvent-based ink printing equipment and under same process condition, use water-based inks just cannot ensure production efficiency and product quality.Be embodied in the temperature of drying oven, stove case length makes cannot ensure bone dry in effective time; And increase drying oven temperature, the blowing of increase hot blast, reduction print speed printing speed etc.; But all also there is certain risk---having after indivedual printing still cannot bone dry, causes part in volume bonding, the problem such as cannot to open and use.And former deflector roll only plays deflector roll effect, change aluminium foil traffic direction, flatten aluminium foil, ensure the effects such as print roller material feeding angle.

Utility model content

The utility model is intended to the deficiency for existing in background technology, and the water color ink printing heating guide roll device proposed.

Water color ink printing heating guide roll device of the present utility model, be made up of roll body and roll shaft, its roll body axis two ends are provided with roll shaft, and roll body is from outer to inner followed successively by roller, zone of heating and interior roller, and in described zone of heating, uniform winding resistive heater.

As further improvement of the utility model, described resistive heater is one, is wound around to center from interior roller two ends simultaneously, and the winding direction at two ends is contrary.

Water color ink printing heating guide roll device of the present utility model, the novel perfect solution of structural design solves water-based inks volatilization problems, on lot of experiments basis, we adopt and change the deflector roll that original deflector roll is band heater, by test solve oven dry not thoroughly, solidification loosely, the problem such as not open after volume volume.Non-stimulated smell, bright in luster, to the features such as adhesive force is good after galley non-corrosiveness, print, residual solvent less on food, drug packing material quality without impact.Organic volatile is little to airborne release, is conducive to environmental protection.

Fig. 2 is the axial sectional view of the utility model.

Detailed description of the invention

Below in conjunction with accompanying drawing 1 and accompanying drawing 2, heating guide roll device is printed to water color ink of the present utility model, be described further.

Water color ink printing heating guide roll device of the present utility model, be made up of roll body 1 and roll shaft 2, its roll body 1 axis two ends are provided with roll shaft 2, and roll body 1 is from outer to inner followed successively by roller 3, zone of heating 4 and interior roller 5, and described zone of heating 4 is that between roller 3 and interior roller 5, uniform winding resistive heater 6.Described resistive heater 6 is one, is wound around to center from interior roller 5 two ends simultaneously, and the winding direction at two ends is contrary.

Water color ink printing heating guide roll device of the present utility model, not only play all effects of original deflector roll, and the heat effect again after antipyretic, printing process heating in advance, print after heating, drying is carried out to aluminium foil, when after print, aluminium foil enters former drying baker like this, moisture in printed portions ink volatilizees, again after drying baker is dried, basic guarantee is mutually sticky not glutinous, by reaching technological requirement completely after curing oven.

Breakthrough existing equipment adopts water-based inks technology to replace traditional solvent-based ink technology.The shortcoming and defect that mainly solution solvent type ink prints food, drug packing material exists and the printing-ink using water color ink to produce are not done, and printing writing, dim pattern are unintelligible, have washmarking, the problems such as poor adhesive force.

Production process: first printing material volume is arranged on the support of pressroom volume position.Spreading materials is rolled up, and wears material artwork, through each deflector roll, printing plate cylinder, heated oven, chill roll, printing material is drawn to rolling position according to equipment.Be entangled on Scroll refill.Load onto galley, added by the ink adjusted in black groove, adjustment doctor, by roller scraping.Switch on power starting device.When equipment normal operation, pressure printing rubber roll.The various patterns carved by printing plate cylinder, writing are transferred to the surface of material, then twine Volume enter Scroll through baking oven heating, drying, each deflector roll.Operate in this way, use solvent type ink technological parameter, water color ink is used to produce, after to change deflector roll be heating guide roll, unintelligible, the poor adhesive force of printing material picture on surface, writing and ink do not have bone dry, printing material is rolled up and produces adhesion between layers, do not reach food completely, these problems of drug packing material printing technology standard are readily solved.
