Description
Technical field
The utility model relates to a kind of electromagnetic heating energy saver of injection molding machine of plastic, in particular, is meant especially and utilizes electromagnetic induction principle, improves the heating efficiency of injection molding machine and reduces scattering and disappearing of heat, and energy-saving effect is remarkable.
Background technology
The mode of heating of existing injection molding machine of plastic forms around barrel with resistance wire or electric heating piece mostly, and passes through the electric heating coil heating that centered on, the plastic raw materials in the barrel is carried out thermosol handle.
This type of heating principle and structure, though generally used by general dealer, but still exist many shortcomings, for example:
First, center on the electric heating coil that forms by resistance wire or electric heating piece, the inside and outside of its electric heating coil all can generate heat, and have only inboard heat energy can conduct on the barrel, but the heat energy in the outside then is lost in the air, therefore, the heat that electric heating coil produced only has half to be absorbed by barrel, and this will cause the loss and the waste of electric energy undoubtedly.
The second, because a large amount of of heat scatter and disappear, make that the temperature around the board raises, have a strong impact on the environment of work and production, force the dealer to install air-conditioning additional and reduce the factory building temperature, the secondary waste that this has not only caused the energy has also increased whole cost.
The 3rd, this heat radiating structure, its heating-up temperature up to 300 ℃ about, the easy Yin Gaowen of resistance wire and produce aging fracture shortens the useful life of electric heating coil, and related increase maintenance cost, and the working efficiency that loses of the machine table stop operation of bringing thus.
The utility model content
The purpose of this utility model just is to provide a kind of electromagnetic heating energy saver of injection molding machine of plastic, utilizes electromagnetic induction to convert electrical energy into the principle of heat energy, improves heating efficiency and reduces scattering and disappearing of heat, thereby reach good electricity-saving efficient.For achieving the above object, the technical solution of the utility model is:
A kind of electromagnetic heating energy saver of injection molding machine of plastic mainly comprises: electromagnetic controller, and its inside is made up of the high-frequency alternating current plate; Heating collar is in the cylinder interior of high temperature insulation panel formation, mainly by 4MM
2～6MM
2Mica higher temperature line coiling form; By described electromagnetic controller AC rectification is become direct current, again with direct current frequency upgrading tremendously high frequency high-tension current, and flow through heating collar and produce the high frequency magnetic field that changes at a high speed, when making it through the magnetic conduction cylinder, produce the little eddy current of high speed in the magnetic conduction cylinder, magnetic conduction cylinder itself is heating at a high speed voluntarily.
This heating collar is located between insulation board cylinder and the magnetic conduction cylinder.
This heating collar size changes with the cylindrical shape of magnetic conduction.
The utility model dissipates by the heat that reduces the heating collar adstante febre, helps the continuous and stable running of board, and the factory building temperature of work is reduced more than 10 degree, avoids using the air-conditioning system or the energy that air exhauster produced to consume and waste; Reduce the problem of the aging and fracture of heating collar; Produce high efficiency heating and uniform heating effect, shorten the barrel heating-up time, improve product yield.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Wherein, 10 electromagnetic controllers; 11 heating collars; 12 magnetic conduction cylinders; 13 insulation boards.
Embodiment
Following conjunction with figs. describes structure composition of the present utility model, technological means and effect in detail.
As shown in Figure 1, electromagnetic heating system of the present utility model mainly is made up of electromagnetic controller 10 and heating collar 11; Wherein, described electromagnetic controller 10 inside are made up of the high-frequency alternating current plate, are used for positive frequency AC rectification is filtered into direct current; And described heating collar 11 is in the cylinder that high temperature insulation panel 13 forms, mainly by 4MM
2～6MM
2Mica higher temperature line coiling form, described heating collar be located at insulation board 13 cylinders and and magnetic conduction cylinder 12 between, and its heating collar 11 big I are with the alteration of form of magnetic conduction cylinder 12.
Secondly, this electromagnetic heater is to be connected to 220V, 50/60HZ AC power on the terminals of electromagnetic controller 10 and earth connection by insulated conductor, connect heating collar 11 by coil two terminals with insulated conductor again, and the high frequency magnetic field that produces through heating collar 11 makes magnetic conduction cylinder 12 indirect.
Once more, the operation principle of this battery electro-heat equipment, mainly be the AC rectification of 220V, 50/60HZ to be become direct current by electromagnetic controller 10, again with the high-frequency high-voltage current of direct current frequency upgrading to 20～40KHZ, and flow through heating collar 11 and produce the high frequency magnetic field that changes at a high speed, when making it, produce the countless little eddy current of high speed in the magnetic conduction cylinder 12, make cylinder heating at a high speed voluntarily itself through magnetic conduction cylinder 12.
In sum, this electromagnetic heating device produces high-power output by low-power, except significantly increasing its heating efficiency and effectively saving the electrification, also can be according to actual conditions at calandria outer wrap sealing heat-insulation and heat-preservation material, reduce the thermal loss on calandria surface, reach the purpose of energy-conserving and environment-protective.
As from the foregoing, the utility model also has more advantage, and only presents and narrate existing novel preferred embodiment at this, and can carry out the Reference numeral that has novel optimal mode now by expection simply and be illustrated; And wherein a plurality of details can improve with many visibly different methods, and all improvement can not deviate from principle of the present utility model, thus above-mentioned accompanying drawing and explanation at this only as in essence explanation, and unrestricted.
