The hot film-covering mechanism of flexible printing press
Technical field
The utility model relates to a kind of flexible printing press, the hot film-covering mechanism of especially a kind of flexible printing press.
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.Up to now, the multiple equipment for coating film of existing different size comes into the market to sell, and needs according to size, the performance parameter of lining workpiece, corresponding the different model of laminating machine, and on technology, be divided into hot overlay film and cold overlay film.At present, hot coating technique has extensively obtained application as the coating technique of comparatively popularizing on the market at present, though hot coating technique has obtained the use even the improvement of different business units, still has complex process, heats insufficient and consumes energy defective such as big.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides that a kind of technology is simple, heating fully and the hot film-covering mechanism of little flexible printing press that consumes energy.
The technical scheme that its technical problem that solves the utility model adopts is: the hot film-covering mechanism of a kind of flexible printing press, it is characterized in that: include frame and install the hot pressing roller on frame and the pressure roller of working, hot pressing roller and work pressure roller are arranged side by side and constitute and relatively rotate with respect to each other, be provided with the storage tank that is provided with vertically in the hot pressing roller, be provided with heating tube in the storage tank, power input is electrically connected with external power source on the heating tube.
Of the present utility modelly further be set to: described storage tank is a strip, and heating tube length and storage tank length are suitable, and the power supply input end is connected to collector ring and damping adjusting part in the Electricity Federation successively on the heating tube, and the damping adjusting part is electrically connected with external power source.
Of the present utility modelly further be set to: also include and unreel assembly, this unreels assembly and installs on frame again, unreels the pressure roller setting of assembly adjacent heat and be arranged in parallel with the hot pressing roller.
The beneficial effects of the utility model are: during work, hot pressing roller and work pressure roller relatively rotate, and film-covered member is carried out overlay film, and the utility model technology is simple, heating is abundant and consume energy little.Be provided with in the containing cavity of hot pressing roller for heating tube, can heat, then can realize the temperature of heating is controlled, satisfy the temperature requirements of different films by regulating the damping adjusting part to the hot pressing roller.The collector ring of power supply input end can satisfy the hot pressing roller and contacts with the brush that external power source electrically connects all the time when rotation work on the heating tube.
Below in conjunction with accompanying drawing the utility model is further described.
Description of drawings
Fig. 1 is the schematic diagram of the utility model embodiment.
The specific embodiment
As shown in Figure 1; present embodiment includes frame 1 and installs and unreel assembly 2, hot pressing roller 3 and work pressure roller 4 on frame 1; unreeling assembly 2 adjacent heat pressure rollers 3 is provided with and be arranged in parallel with hot pressing roller 3; required hot melt diaphragm 8 is installed in unreeling on the assembly 2; hot pressing roller 3 and work pressure roller 4 are arranged side by side and constitute and relatively rotate with respect to each other; enter the compressed part place of 4 of hot pressing roller 3 and work pressure rollers with making film-covered member and hot melt diaphragm 8 overlapped formulas, realize that thus film-covered member and hot melt diaphragm 8 fit together under the hot pressing of hot pressing roller 3.Be provided with the storage tank 31 of the strip that is provided with vertically in the hot pressing roller 3, be provided with in the storage tank 31 and the suitable heating tube 5 of storage tank 31 length, power input is provided with collector ring 6 and damping adjusting part 7 on the heating tube 5, power input and collector ring 6 electrically connect on the heating tube 5, collector ring 6 electrically connects with damping adjusting part 7, damping adjusting part 7 is electrically connected with external power source, in the utility model, during work, hot pressing roller 3 and work pressure roller 4 relatively rotate, and film-covered member carried out overlay film, the utility model technology is simple, heating fully and consume energy little.Be provided with in the containing cavity 31 of hot pressing roller 3 for heating tube 5, can heat, then can realize the temperature of heating is controlled, satisfy the temperature requirements of different films by regulating damping adjusting part 7 to hot pressing roller 3.The collector ring 6 of power supply input end can satisfy hot pressing roller 3 and contacts with the brush that external power source electrically connects all the time when rotation work on the heating tube 5.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.
