Hyperacoustic frequency electromagnetic bowl energy-saving heating apparatus

Abstract

An energy saving heating device for a superaudio electromagnetic drum comprises a hollow drum and an electromagnetic induction heater; the invention is characterized in that the electromagnetic induction heater can be rotatablely arranged in the drum according to the drum; besides, a clearance is arranged between the electromagnetic induction heater and the drum; compared with the prior art, the energy saving heating device of the invention has the beneficial effects of eliminating the leakage phenomenon of the mode of circular heating by heat conduction oil as the electromagnetic induction technology is adopted, being incapable of generating oil mist and being incapable of affecting the working environment either; therefore, the production efficiency is substantially improved and simultaneously the invention is more environmental friendly; besides, if the traditional heating by the heat conduction oil needs a heating power about 36kW, then a heating power about 10kW is needed if the electromagnetic induction heater is adopted, therefore the energy consumption is substantially reduced and the manufacturing cost is reduced; besides, as the temperature control precision can reach plus or minus 0.5 DEG C, the quality of the product can be better ensured.

Description

technical field [0001] The invention relates to a laser molding machine, in particular to an energy-saving heating device for a super-audio frequency electromagnetic roller. Background technique [0002] The traditional manufacturing method of laser packaging film is: the use of batching, coating, molding, aluminum plating, back glue, slitting, rolling and other process steps. The process is as follows: first, mix the resin and dyes with a disperser to form a laser coating; then use a coating machine to coat the mixed laser coating on the PET polyester film to be processed, and dry it; then use a molding machine to emboss The pattern is on the above coating; the molded coating film is sent to the vacuum aluminum coating machine for aluminum coating; the aluminum surface after the aluminum coating is coated with hot melt primer and dried; It is required to be rolled into products of different lengths. [0003] In the molding process, the molding machine adopts single-roller...

AI Technical Summary

Problems solved by technology

However, due to the form of heat conduction oil circulation heating, it must be transported through a long pipeline, and then the heat conduction oil is introduced into the inner cavity of the roller through the rotary joint. Oil heating requires approx. 36kW heating power)

Since the production of laser thin films requires a very clean working environment, and it is difficult to eliminate dripping by means of thermal oil circulation heating, the oil mist generated will affect the working environment and restrict the development of production to a certain extent.
