Description

A kind of plasticity machines heater with quick cooling function
Technical field
The present invention relates to plasticity machines technical field, and in particular to a kind of plasticity machines heating dress with quick cooling function Put.
Background technology
At present, plastic products industry is that plasticity machines are heated using Far infrared electric heating mode and Electromagnetic Heating mode. But it is due to that Far infrared electric heating device is a kind of mode of heating of resistance heat, its heating efficiency is relatively low, now major businessmans It is substantially all and is heated using Electromagnetic Heating mode for plasticity machines.Generally use electromagnetic heater, every group of electrical induction coil Maximum Power Output can only achieve 1.5KW, and length can only achieve 80mm, far from the use for meeting plastics machinery and rubber manufacturing machinery It is required that, if carrying out multigroup (12-13 groups need to be reached) coil combination, significantly reduce energy-saving effect;In heating process, a lot Heat losses, cause larger waste;And plasticity machines, when needing cooling, it radiates slow, it is necessary to longer time.
The content of the invention
It is an object of the invention to provide a kind of plasticity machines heater with quick cooling function, to solve the above-mentioned back of the body The problem of being proposed in scape technology.
To achieve the above object, the present invention provides following technical scheme:
A kind of plasticity machines heater with quick cooling function, including barrel, extrusion screw rod, electromagnetic induction heater And heating coil, the extrusion screw rod be located at barrel in, be wound with cooling pipe on the lateral wall of barrel;The cooling pipe Outer cover is provided with heat insulation layer, and the heat insulation layer is made up of outer layer and internal layer, and vacuum lumen is constituted between the outer layer and internal layer;Institute State and heating coil is provided with the outside of outer layer, heating coil uses cartridge type heat stepwise.
It is used as further scheme of the invention:The water inlet end of the cooling pipe is connected with magnetic valve.
It is used as further scheme of the invention:The cooling pipe is made up of aluminum metal.
It is used as further scheme of the invention:The heating coil is electrically connected with electromagnetic induction heater.
The beneficial effects of the invention are as follows magnetic valve is opened, cooling water is injected into cooling pipe cold to barrel progress cooling But, its cool time is short, and cooling rate is fast;Due to the setting of vacuum lumen so that heat losses slow down, fractional energy savings is improved, Reduce production cost;Pass through the heat stepwise of heating coil so that the temperature of each several part is uniform in barrel, improve product quality.
Brief description of the drawings
Fig. 1 is structural representation of the invention;
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete Site preparation is described, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole embodiments.It is based on Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of creative work is not made Embodiment, belongs to the scope of protection of the invention.
Referring to Fig. 1, in the embodiment of the present invention, a kind of plasticity machines heater with quick cooling function, including material Cylinder 2, extrusion screw rod 1, electromagnetic induction heater 6 and heating coil 5, the extrusion screw rod 1 are located in barrel 2, the outside of barrel 2 Cooling pipe 3 is wound with wall, the water inlet end of the cooling pipe 3 is connected with magnetic valve, when needing cooling, opens electromagnetism Valve, cooling water is injected into cooling pipe 3 to the progress cooling down of barrel 2, its cool time is short, and cooling rate is fast;
The outer cover of the cooling pipe 3 is provided with heat insulation layer 4, and the heat insulation layer 4 is made up of outer layer 41 and internal layer 42, described Vacuum lumen 43 is constituted between outer layer 41 and internal layer 42, due to the setting of vacuum lumen 43 so that heat losses slow down, is improved Fractional energy savings, reduces production cost;
The outside of outer layer 41 is provided with heating coil 5, and heating coil 5 uses cartridge type heat stepwise, passes through heating coil 5 Heat stepwise so that the temperature of each several part is uniform in barrel 2, improves product quality.
The cooling pipe 3 is made up of aluminum metal.
The heating coil 5 is electrically connected with electromagnetic induction heater 6.
The present invention the course of work be:When needing cooling, magnetic valve is opened, cooling water pair is injected into cooling pipe 3 Barrel 2 carries out cooling down, and its cool time is short, and cooling rate is fast;Due to the setting of vacuum lumen 43 so that heat losses subtract It is slow, fractional energy savings is improved, production cost is reduced;Pass through the heat stepwise of heating coil 5 so that the temperature of each several part in barrel 2 Uniformly, product quality is improved.
It is obvious to a person skilled in the art that the invention is not restricted to the details of above-mentioned one exemplary embodiment, Er Qie In the case of without departing substantially from spirit or essential attributes of the invention, the present invention can be realized in other specific forms.Therefore, no matter From the point of view of which point, embodiment all should be regarded as exemplary, and be nonrestrictive, the scope of the present invention is by appended power Profit is required rather than described above is limited, it is intended that all in the implication and scope of the equivalency of claim by falling Change is included in the present invention.Any reference in claim should not be considered as to the claim involved by limitation.
Moreover, it will be appreciated that although the present specification is described in terms of embodiments, not each embodiment is only wrapped Containing an independent technical scheme, this narrating mode of specification is only that for clarity, those skilled in the art should Using specification as an entirety, the technical solutions in the various embodiments may also be suitably combined, forms those skilled in the art It may be appreciated other embodiment.
