Description
Technical field
Press apparatus field is the utility model is related to, specifically a kind of hot press heating plate.
Background technology
Wood-based plate at present（Furniture）Production generally needs to use hot press, and the thermal source of hot press is from press at present
External heat source, such as（Fire coal, fuel oil, combustion gas etc.）Boiler combustion produces heat energy and transfers thermal energy to heat by steam or conduction oil
The heating platen of press supplies sheet material（Furniture）Hot pressing is bonded.It is known that energy transmittance process along with energy loss, while by
The reduction of the thermal efficiency is caused make it that efficiency is very low in the influence of heat exchange efficiency, therefore in energy-conservation and economically in the presence of greatly wave
Take.
Simultaneously because producing waste gas, dust and small particle while boiler combustion consumption fuel, oxygen gives big compression ring
Cause greatly to pollute in border.Part use biomass fuel due also to sintering cause boiler part long-time high fever to cause boiler
Produce the phenomenon burnt.Also be exactly in the disaster hidden-trouble that fuel combustion is brought, and steam, conduction oil transmitting procedure pipeline let out
Reveal the potential safety hazard brought.Therefore installation, maintenance, maintenance and the security protection cost that traditional mode of heating is brought are high.
Also there are the miniature boiler using Electric heating heating conduction oil and the pot using Electromagnetic Heating mode in recent years
The new technologies such as stove, but all exist clearly disadvantageous.No matter the mode which kind of mode to be heated the heat transfer carrier of conduction oil using is all belonged to
Can all there are heat conduction losses in heat transfer mode of heating.
The hot press electric hot plate of Patent No. 201610396983.4, it is using resistance heating manner, and it is substantially also
It is to use conduction-type mode of heating, first passing through electric energy makes resistance produce heat energy and then transmit heat energy by way of contacting and conducting
To heating platen, its deficiency is the heat energy loss that heat transfer is brought first, secondly, safety is there are if resistance puncture short etc.
Hidden danger.
Patent No. 201620389120.X heating means of hot press and the hot press equipped with the heater, the patent
Employ the principle of electromagnetic induction heating.Although the energy loss problem that existing conduction heating techniques are brought is overcome, simultaneously
The defects of following several respects be present：First, 3-6 independent wire casings and corresponding line are set described in the patent inside heating plate
Circle, due to independent wire casing and the mechanical structure of corresponding area coil conference destruction press plates, it can apply during compressor operation
Very big pressure（The pressure of now universal artificial plate pressing machine is all at 260 tons or so）And press plates are caused to become because stress is recessed
Shape, while immense pressure can make wire casing and damaged even coil short or the open circuit of corresponding coil during compressor operation；Secondly, should
There is no the material of clear and definite fixed plate and thickness its thermodynamic property not to know in patent, it is particularly pressed during compressor operation
The impact that ftercompction is brought when machine works is easy to make fixed plate damaged；Have again is exactly that the limitation that wire casing and coil are set easily causes
Whole plate（Heating platen）Temperature distributing disproportionation is even, plank（Furniture）Whether fitting is evenly distributed to each spot temperature of heating platen requires pole
Height, local temperature is too high to cause fitting plate face to be carbonized, and local temperature is relatively low to cause plate face fitting loosely（Due to plate face
It is bonded using adhesive and adhesive fitting solidification needs certain temperature）And come unglued；Further, using upper described in the patent
The mode of lower heating plate, it is effectively to do work that magnet coil only has a face in the course of the work, the electromagnetic energy in another face
Amount is wasted, at the same if another side exist can if the metal of induced electricity magnetic wave if the part can induced electricity magnetic wave produce and induct
Electric current or heating, potential safety hazard is brought while electric energy is wasted.In addition, described in the patent, " bottom plate is fixed on platform
On " so also just limit to the working method and efficiency of the press.
