The modified bronzing roller
Technical field
The utility model relates to a kind of modified bronzing roller, particularly is used in the bronzing roller on the rotary-cutting hot stamping machine.
Background technology
In the processing technology of printing, gold stamping is common, and the most frequently used blanching can be divided into flat boiling hot and round scalding, and blanching mode of heating commonly used has electric heating and oily hot.Electric heating is that energising makes heating and stablizes its temperature with temperature controller to the resistance wire in the heating plate.Its cost simple in structure is low, is widely used in flat scalding.
Employed bronzing roller in the existing rotary-cutting hot stamping machine, comprise circular roller, be arranged on the oily hot-rolling in the circular roller, and several gold stamping templates that are arranged on circular roller surface, described oily hot-rolling and described circular roller interference fits, this bronzing roller adopts oily hot mode to heat usually.So-called oily heat also is electric heating in fact, and it is that heater is placed in the fuel tank, and the temperature of oil is stable with temperature controller, delivers to oily hot-rolling one end with oil pump through oil pipe through the oil of heating, flows through oily hot-rolling inside, is flowed out by the other end, flows back to fuel tank through oil pipe.In this deep fat one-in-and-one-out, oily hot-rolling is heated by deep fat, oily hot-rolling and then heat circular roller again and gold stamping template; Deep fat in the oily hot-rolling that also has is to advance from an end, is both also to bring out from this, and this oily hot-rolling is after deep fat enters in the oily hot-rolling from oil-in, and flow out from the oil-out that is positioned at same side the back of turning back again, flows back to fuel tank through oil pipe.This system architecture complexity, technological requirement high cost height, the fuel tank volume is big, and the fuel tank of high temperature can bring the unfavorable factors such as environment of high temperature to restrict its extensive use at the workshop heat dissipation.In addition, when this bronzing roller is changed circular roller, the time that needs is long, when it need be cooled to whole bronzing roller can operate, just oily hot-rolling can be separated with circular roller, thereby change new circular roller, if wait until whole bronzing roller cooling, the bronzing roller of next 330 millimeters long of ordinary circumstance needs about 4 hours, will have influence on the operation of whole streamline like this, loses very big; So, some user is when saving roll change, just take to pull down whole bronzing roller, change new bronzing roller, user's a few cover bronzing roller of polygamy adapted of just having to so, not only takies user's stock place like this, but also to increase the quantity in stock and the amount of circulating funds used of bronzing roller, increase the cost of keeping bronzing roller; And the firing rate of oil heat heating is slow, and it just can heat bronzing roller after needing elder generation with the cold oil heating again, needs certain hour, and is bigger to the production influence of continuous processing line.
