Description

Film high speed flexible printing machine

Technical field

The present invention relates to the field of printing machine, especially a kind of film high speed flexible printing machine.

Background technology

Printing machine is the machine of a kind of printing word and image; Modern printing machine is generally formed by locing up, be coated with China ink, impression, defeated paper mechanisms such as (comprising folding); Its operation principle is: the writings and image that will print is earlier processed forme; Be contained on the printing machine; Be coated on the place that writings and image is arranged on the forme to China ink by manual work or printing machine then, be transferred to directly or indirectly again on paper or other stocks (like textile, metallic plate, plastic cement, leather, plank, glass and pottery), thereby duplicate from the identical printed matter of forme.

Printing machine divides according to the forme form can be divided into relief printing plate, lithographic plate, intaglio plate and porous printer, letterpress: card printer, font printing, zincograph, cover Number character etc.; Offset press: polychrome machine, four-color machine, double-colored machine, monochromatic machine, quick print machine etc.; Intaglio press: the glass bag printing of instant noodles, the packaging of aluminium foil bag of biscuit etc.; Screen process press: circuit board printing, the printing of cloth flower printing inscription version etc.

Printing machine is classified according to printing chromatic number and face number: monochrome press, two color printing machine, multicolour press, two-sided monochrome press, double-side multicolor printing machine.

The function that on film process printing printing machine, does not also have at present chromaticity printing is often printed a color on a printing machinery, then with being placed into second color of printing on another printing machinery after the film take-up again; In the process of film take-up, great majority are through the swaying of wind-up roll, and film is carried out rolling; Such rolling mode causes the phenomenon that when the rolling thin-film material, causes sideslip easily, and the rolling end face is irregular, wrinkle etc. occurs, and rolling is dried through a drying unit after finishing again; The oven dry of adopting as the one of which is that electrical heating prevents, such drying mode can not use the drying of printing ink, and its power is big; Power consumption is big, and heats is bad, and so far a whole set of typography is very complicated like this; Cause the phenomenon of the entanglement of chromatography position easily, production efficiency is low.

Summary of the invention

The technical problem that the present invention will solve is: in order to overcome the above-mentioned middle problem that exists, solved the problem of a plurality of colors of press printing, a kind of film high speed flexible printing machine is provided, the low and high efficiency of its power consumption.

The technical solution adopted for the present invention to solve the technical problems is: a kind of film high speed flexible printing machine; Comprise base and be fixed on door character type column and the control circuit on the base; Described column is made up of left column, right column and the crossbeam that is fixed between the left and right column; Described left column be provided with let off roll mechanism; Right column be provided with wind-up roll mechanism; Be disposed with the first look printing mechanism and the second look printing mechanism and first heating cabinet on the described left column, be provided with the first transfer printing pressure roller and the first transfer printing ink roller between the first look printing mechanism and the second look printing mechanism, be disposed with three-colour printing mechanism and the four-color process mechanism and second heating cabinet on the described right column; Be provided with the second transfer printing pressure roller and the second transfer printing ink roller between three-colour printing mechanism and the four-color process mechanism; On the described crossbeam heater is installed, described heater comprises heating cabinet, be installed in few one group of heating sheet and blower fan that is connected with heating cabinet and the hot-gas system that is connected with heating cabinet in the heating cabinet, and described hot-gas system is connected with second heating cabinet with first heating cabinet respectively.

In order to improve drying efficiency and power consumption is low; Described hot-gas system comprises the hot gas case gauge tap outside with being installed in the hot gas case that is connected with heating cabinet; Offer air supply pipe on the hot gas case; Air supply pipe is connected with first heating cabinet and second heating cabinet respectively, in the described hot gas case temperature controller is installed, and temperature controller is connected with gauge tap.

In order in rolling, to keep the steady rolling of thin-film material; The phenomenon of fold does not neatly appear in end face; Described wind-up roll mechanism comprises nip rolls, the wind-up roll that is arranged on second heating cabinet below and is socketed in the lever arm on the nip rolls two ends and is arranged on the roll on the lever arm that described lever arm is suspended on the wind-up roll top.

The invention has the beneficial effects as follows: described film high speed flexible printing machine, adopt this equipment, can solve the problem of the printing of a polychrome of film effectively, chromatography is stable, printing quality is good and print speed printing speed is fast, percent defective is low; Adopt this kind drying plant, can reduce power consumption, enhance productivity, reduce production costs; Adopt this kind wrap-up, its rolling is convenient and avoided deviation phenomenon, and its profile is novel, mechanism design is reasonable, simple to operate, long service life and maintaining easily.
