Flexible printing press cold wave mechanism
Technical field
The utility model relates to a kind of flexible printing press, especially a kind of flexible printing press cold wave mechanism.
Background technology
Flexible printing press enters China from the nineties in last century, what flexible printing press used is water color ink, and environmental pollution is less, and flexible plate making technology is simple, fast, than gravure plate-making clear superiority on the efficient is arranged.In the actual production,, protect, just need carry out overlay film at its outer surface as the surface of all kinds of drawings, picture, advertisement, document information etc. for lithographic substrate to coming out through flexible printing press, or be called the table cover.
Thermoprint is a kind of common surface decorating method, is used to strengthen the visual effect of products such as label, carton, trade mark.The thermoprint mode mainly comprises two kinds on blanching seal and cold wave seal.The blanching seal is to utilize the metal printing plate by heating, pressing mode stamping systems to be transferred to the material surface of promising.The cold wave seal utilizes ultraviolet curing gloss oil (also claiming the UV gloss oil) that stamping systems is transferred to the material surface of promising usually, the blanching of comparing seal, and the power consumption of cold wave seal is low, equipment investment is few, the plate-making cost is low, production efficiency is high.But existing flexible printing press substantially all only is equipped with blanching mechanism, and does not have to adopt the cold wave mechanism with a lot of advantages.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of flexible printing press cold wave mechanism that is installed on the flexible printing press.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of flexible printing press cold wave mechanism, it is characterized in that: include frame and install the rolling assembly that unreels assembly, printing assembly and be positioned at the printing assembly rear on frame, be provided with the drying box assembly between printing assembly and the rolling assembly, printing assembly includes pressure roller, version roller and bottom roller, and triangular in shape closely the extruding mutually of pressure roller, version roller and bottom roller is provided with.
Of the present utility modelly further be set to: describedly unreel that assembly comprises let off roll and the guiding roll assembly that is complementary with it constitutes.
Of the present utility modelly further be set to: described rolling assembly comprises wind-up roll and the guiding roll assembly that matches constitutes again.
The beneficial effects of the utility model are: install cold wave mechanism on the flexible printing press, and the relatively hot ironing process, it is low not only to consume energy, and equipment investment is few, has reduced the plate-making expense, has also improved production efficiency simultaneously.
Below in conjunction with accompanying drawing the utility model is further described.
Description of drawings
Fig. 1 is the assembling schematic diagram of the utility model embodiment.
The specific embodiment
As shown in Figure 1, present embodiment includes frame 1 and installs the rolling assembly 3 that unreels assembly 2, printing assembly 4 and be positioned at printing assembly 4 rears on frame 1, be provided with drying box assembly 5 between printing assembly 4 and the rolling assembly 3, printing assembly 4 includes pressure roller 41, version roller 42 and bottom roller 43, pressure roller 41, version roller 42 and bottom roller 43 closely extruding settings mutually triangular in shape, unreel guiding roll assembly 22 formations that assembly 2 comprises let off roll 21 and is complementary with it, guiding roll assembly 32 formations that rolling assembly 3 comprises wind-up roll 31 and matches.Printing product 6 is by pressure roller 41, version roller 42 and bottom roller 43, from between the three through out-of-date, printing printing ink on the printed matter 6, and the curing adhesive that passes through on the bottom roller 43 needs extraordinary curing adhesive in the gold stamping position printing in ink pellet surface, so just on printed matter 6, form the full-bodied extremely thin viscose of one deck, printed matter 6 is carried out cold wave.Simultaneously, press together at the pressing position of bottom roller 43 and pressure roller 41 through unreeling the film that assembly 2 emits, drying box assembly 5 is with the moisture removal of adhesive then.
In the utility model, install cold wave mechanism on the flexible printing press, the relatively hot ironing process, it is low not only to consume energy, and equipment investment is few, has reduced the plate-making expense, has also improved production efficiency simultaneously.The utility model can also have other embodiments, and the technical scheme that equal replacement of all employings or equivalent transformation form all drops within the claimed scope of the utility model.
