Abstract
The utility model provides a kind of high-frequency electromagnetic induction sheet material machine screw heating device, it comprises spiro rod machine tube and inner screw rod, the outer wall of described spiro rod machine tube is wound with current coil, spiro rod machine tube and current coil are coated with thermal insulation layer, the high frequency power module of described current coil two ends connection control coil current.Described thermal insulation layer comprises again the asbestos of internal layer and outer field XPS warming plate.The utility model has the advantages that: by being arranged on the current coil on spiro rod machine tube lateral wall, producing heat by the fluctuation of electric current and electromagnetic induction principle, and by the diffusion of thermal insulation layer caloric restriction outside current coil.Pass into high frequency electric, screw rod heats up because of electromagnetism pressure; And pass through the diffusion of thermal insulation layer caloric restriction, effectively save energy consumption.
Description
Technical field
The utility model relates to a kind of heater, specifically a kind of high-frequency electromagnetic induction sheet material machine screw heating device.
Background technology
Sheet material machine is a kind of a kind of production equipment producing novel hot setting moulded plastic, the extrusion system that machine barrel and screw rod be jointly made up of of plastic pellet on sheet material machine plastifies, existing sheet material machine goes into operation warm-up phase, heated by spiro rod machine tube external heat part (employing electric heating earthen), electric energy convert to heating watt heat energy, what utilize heating watt and spiro rod machine tube outer wall contacts transferring energy, thus carries out heating plasticizing to spiro rod machine tube interpolymer.There is heat like this, to be delivered to the screw rod annex polymer heat time long, and the efficiency of heating surface is low, and the consumption of electric energy is large, the shortcoming of result of use difference.
Summary of the invention
The purpose of this utility model overcomes the deficiencies in the prior art, provides a kind of high-frequency electromagnetic induction sheet material machine screw heating device, realize better heating effect.
According to the technical scheme that the utility model provides, described high-frequency electromagnetic induction sheet material machine screw heating device comprises spiro rod machine tube and inner screw rod, the outer wall of described spiro rod machine tube is wound with current coil, spiro rod machine tube and current coil are coated with thermal insulation layer, the high frequency power module of described current coil two ends connection control coil current.
Described thermal insulation layer comprises again the asbestos of internal layer and outer field XPS warming plate.Wherein, the thickness of asbestos is the thickness of 15 ~ 18mm, XPS warming plate is 20 ~ 23mm.
The utility model has the advantages that: by being arranged on the current coil on spiro rod machine tube lateral wall, producing heat by the fluctuation of electric current and electromagnetic induction principle, and by the diffusion of thermal insulation layer caloric restriction outside current coil.Pass into high frequency electric, screw rod heats up because of electromagnetism pressure; And pass through the diffusion of thermal insulation layer caloric restriction, effectively save energy consumption.
Accompanying drawing explanation
Fig. 1 is apparatus structure schematic diagram of the present utility model.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail.
As shown in Figure 1, high-frequency electromagnetic induction sheet material machine screw heating device of the present utility model, comprise spiro rod machine tube 1 and inner screw rod 7, spiro rod machine tube 1 material is nonmetal easy Heat Conduction Material, screw rod 7 material has No. 45 steel, nitrated steel, 38CrMOAl, high temperature alloy etc.The outer wall of described spiro rod machine tube 1 is wound with current coil 2, and spiro rod machine tube 1 and current coil 2 are coated with thermal insulation layer 3, the high frequency power module 4 of described current coil 2 two ends connection control coil current.During use, control current coil 2 by high frequency power module 4 and work, by fluctuation and the electromagnetic induction principle generation heat of electric current, thus spiro rod machine tube 1 inner screw 7 is heated.
Described thermal insulation layer 3 comprises the asbestos 5 of internal layer and outer field XPS warming plate 6.Asbestos 5 and XPS warming plate 6 have the effects such as heat insulation, sound-absorbing, damping.The thickness of asbestos 5 is 15 ~ 18mm, and the thickness of described XPS warming plate 6 is 20 ~ 23mm.In an embodiment, asbestos 5 thickness that we adopt is 15mm, XPS warming plate 6 thickness is 20mm, and thickness is that the thermal insulation layer 3 of 35mm is coated on the outer wall of the spiro rod machine tube 1 being provided with at least one group of current coil 2.
Described current coil 2 wrapped anti-clockwise is on spiro rod machine tube 1, and two ends are reliably connected with high frequency power module 4, is convenient to produce magnetic flux thus eddy-current heating screw rod 7.
