Description
Technical Field
The utility model relates to the field of printing technology, concretely relates to a gilt roller of circle is pressed to circle for connecing dress paper rapid heating of can fixing a point.
Background
Gilding presses are one of the most popular special devices in the printing industry. It can be used for gold stamping of printed products, and has been well accepted all the time.
The temperature has very important influence on gold stamping: the temperature must be controlled within a corresponding range to properly melt the dyed resin layer and the adhesive, so that good transfer of the aluminum layer can be ensured. If the temperature is too high, the melting is excessive. The alumite around the hot stamping graph and text is also melted and falls off to cause pasting, and simultaneously, the high temperature can cause chemical changes of the alumite dyeing resin and the aluminum layer, so that the brightness of the hot stamping product is reduced, the metal luster is lost, and even the print is in a foggy spot shape or bubbles. However, if the temperature is too low, the ink is not fully melted, and the ink cannot be hot-stamped or hot-stamped firmly, the print is not firm, is easy to fall off, is broken due to pen shortage, and is colored. Generally, the electric heating temperature is controlled to be 70-180 ℃, the hot stamping area is large, the electric heating temperature is relatively high, and for fine characters and lines, the hot stamping area is small, and the temperature is lower. Meanwhile, the suitable hot stamping temperatures of various types of alumite are different. The ideal hot stamping temperature is the standard of the lowest and clear lines which can be stamped.
It is known that, in the currently used rotary gilding press, a plurality of square plates engraved with hot-stamping pictures and texts are embedded on the surface of a cylindrical roller according to a certain arrangement rule, the roller is heated by introducing hot oil or a built-in electric heating wire during gilding, and the roller is integrally heated in order to ensure that the temperature of the plurality of square plates is uniform, but the form has at least two defects.
Firstly, the integral heating energy consumption of the roller is large, when the gold stamping is carried out, the part needing heating and pressurizing is actually the square plate position, and the integral heating can cause great waste of heat; and the whole heating consumes long time, and the startup preparation time and the maintenance waiting time are long, so that the effective working time of the equipment is short, and the utilization rate of the equipment is low.
Secondly, after the roller is heated integrally, the electrochemical aluminum film passes through the position between the gold stamping roller and the pressure-bearing rubber roller and can be heated integrally, and because the electrochemical aluminum hot stamping foil is very thin, slight deformation can occur under the action of high temperature, and then the problem that the hot melt adhesive cannot be completely cooled and solidified can occur in the process of entering the winding shaft through the middle roller, so that the back sticking phenomenon of the electrochemical aluminum in the rewinding process is caused, and the repeated utilization of the non-hot stamping part of the electrochemical aluminum hot stamping foil is influenced.
The prior patent documents disclose locally heated gold stamping rollers, such as (1) "CN202121488162.6 gold stamping roller locally heated gold stamping machine", and (2) "CN201320562671.8 an electromagnetic induction local heating mechanism"; for the document (1), the local heating is realized by embedding the annular electric heating pipe at the specific part of the gold stamping roller, but actually, the scheme cannot solve the problems that the overall heating time is long in an electric heating mode, the startup preparation time and the maintenance waiting time are long, the effective working time of equipment is short, and the utilization rate of the equipment is low, and meanwhile, because the heat of electric heating is uniformly diffused to the periphery, the annular electric heating pipe in the scheme heats the raised gold stamping part, and meanwhile, other parts of the gold stamping roller are continuously heated, and finally, the problem of overall heating still exists; as for the document (2), according to the scheme, an induction heating plate and an electromagnetic inductor are arranged below a gold stamping plate, the electromagnetic inductor heats the heating plate and then transfers heat to the gold stamping plate, but the commonly used electromagnetic heating can heat up to 500-600 ℃, which far exceeds the temperature required by gold stamping, and the condition of controlling the heating temperature cannot be realized in gold stamping equipment; secondly, the power of electromagnetic heating only determines the heating speed of the electromagnetic heater, and has no direct relation with the heating temperature, so that the temperature cannot be controlled by reducing the power, and the device can only set the maximum power, and the electromagnetic heater with the extremely high switching frequency can theoretically adapt to the speed and temperature requirements for telling gilding, so that the realization difficulty is high.
