Abstract
The invention discloses an electromagnetic eddy current induction heating roller, comprising a transmission roller whose left end and right end are provided with end caps; an inner tube wound with a coil group is arranged inside the transmission roller; the lead of the coil group threads through the left and the right end caps to be connected with a power source. Based on the principle of magnetic inductive eddy current heating, firstly, industrial-frequency alternating current of the power grid is converted into direct current and then a control circuit converts the direct current to high- frequency alternating current which makes the inner tube generate high-frequency alternating magnetic field through the circular coil group wound on the inner tube. When the iron substrate turns the roller under the effect of the high-frequency alternating magnetic field, a large number of small eddy currents will be generated, so that the transmission roller will heat automatically to the temperature set by the controller. With simple structure, low energy consumption and no pollution, the invention can be widely applied to hot compound devices.
Description
Technical field
The present invention relates to a kind of hot pressing roller, particularly a kind of electromagnetic vortex induction heating type roller cylinder.
Background technology
The hot pressing roller is one of critical piece in the hot equipment complex, and it mainly is that materials such as plastics, cloth, fiberboard, plank, metallic plate are carried out the heat pressure adhesive moulding, and traditional hot pressing mainly is to adopt dual mode with the thermal source of roller:
1, with boiler liquid medium is heated to required temperature, the reusable heat pump makes the liquid medium that the is heated heating that circulates in roller, and this design makes the thermal efficiency low, and energy loss is big, promptly wastes energy and has increased production cost;
2, place the inner energising heating of roller with the resistance heat-generating pipe, the component structural complexity of this design, not only there is potential safety hazard in the equipment manufacturing cost height, also causes corrective maintenance, maintenance complicated, the expense height, thus be difficult to meet people's instructions for use.
So develop a kind of research schedule that does not have pollution, energy consumption electromagnetic vortex induction heating type roller cylinder little, simple in structure to put on people.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides a kind of do not have pollution, energy consumption electromagnetic vortex induction heating type roller cylinder little, simple in structure.
The technical solution adopted in the present invention is:
A kind of electromagnetic vortex induction heating type roller cylinder, it comprises the rotation roller, and the left and right two ends of rotating roller are provided with plug, rotate in the roller and are provided with the interior pipe that solderless wrapped connection has coil groups, and the lead of coil groups passes left and right plug and is connected with power supply;
As further improvement, be provided with rolling bearing between described left and right plug and the rotation roller to above-mentioned embodiment.
The invention has the beneficial effects as follows: this product adopts magnetic field induction eddy current heating principle, at first the industrial-frequency alternating current with electrical network becomes direct current, by control circuit this direct current is become high-frequency alternating current again, this high-frequency alternating current is by solderless wrapped connection loop coil group on inner pipe, make it to produce high-frequency alternating magnetic field, when this action of alternating magnetic field rotates roller in ferrous substrate, produce countless little eddy current, rotation roller itself is generated heat voluntarily to the temperature of controller appointment.This design is not only simple in structure, and energy consumption is little, do not pollute, thereby can be widely used on the roller in the hot equipment complex.
Description of drawings
The present invention is further described for following accompanying drawing.
Fig. 1 is a structural representation of the present invention;
Fig. 2 is a circuit theory frame diagram of the present invention.
The specific embodiment
With reference to Fig. 1, a kind of electromagnetic vortex induction heating type roller cylinder, it comprises that ferrous substrate rotates roller 1, the left and right two ends of rotating roller 1 are provided with plug 2,3, rotate pipe 4 in the non iron that is provided with solderless wrapped connection in the roller 1 and has coil groups 5, the lead 51,52 of coil groups 5 passes left and right plug 2,3 and is connected with power supply.
This product is more smooth and easy in order to make that rotation roller 1 rotates, and is provided with rolling bearing 6 between described left and right plug 2,3 and the rotation roller 1.
This product adopts magnetic field induction eddy current heating principle, at first the industrial-frequency alternating current with electrical network becomes direct current, by control circuit this direct current is become high-frequency alternating current again, this high-frequency alternating current is by the loop coil group 5 of solderless wrapped connection on interior pipe 4, make it to produce high-frequency alternating magnetic field, when this action of alternating magnetic field rotates roller 1 in ferrous substrate, produce countless little eddy current, rotation roller 1 itself is generated heat voluntarily to the temperature of controller appointment.This design is not only simple in structure, and energy consumption is little, do not pollute, thereby can be widely used on the roller in the hot equipment complex.
With reference to Fig. 2, coil groups 5 and ferrous substrate rotate between the roller 1 has only getting in touch of magnetic, and does not have the contact of electricity.Owing to be wound in to rotate and pass through the very high alternating current of frequency in the roller 1 inner non iron in the coil groups 5 on the pipe 4, its frequency is 25 ~ 30KHz, thereby rotating the roller 1 inner alternating magnetic field that produces same frequency, owing to rotate roller 1 is that conductor and shell constitute a closed-loop path, thereby in rotating roller 1, induce very big eddy current, owing to rotate roller 1 resistance effect heating, make and rotate the rising of roller 1 temperature, reach heating purposes.
The heating winding is perceptual, long-time conducting of switch or not conducting, owing to do not suddenly change, inductance is equivalent to short circuit by the electric weight in the inductance, and the stable back of circuit can not produce high-frequency ac owing to having only direct current to be in open circuit or short-circuit condition.Under the high speed triggering of switch at the control circuit trigger impulse, the electric weight in the circuit is undergone mutation, and according to the Lenz's law principle, in the moment of opening and disconnecting, the inductance two ends produce opposite electromotive force.Coil groups 5 is by capacitor C 1, and C2 constitutes oscillating circuit, thereby induces the alternating magnetic field of same frequency.Need only the frequency of control trigger impulse, just can control the frequency of electric current in the heater coil, change the magnetic field that produces, and then change eddy current, just rotation roller 1 can be heated to the temperature of appointment.
