Description
Technical field
The utility model relates to a kind of plastic rubber shaping machinery, specifically is a kind of plastic cement plate squeezing machine.
Background technology
Plastic cement plate squeezing machine comprises plastic extruder and roller calender, and with the plastic material heat fused and after extruding, the pulley type calender is pressed into plate with plastic cement by plastic extruder.
The existing main energy consumption of plastic extruder is at electric heating system.Heat form is the resistance wire heating, and temperature control system is that the conventional electrical temperature controller adds the blower fan cooling.When promptly being electrically heated to the temperature value of setting, turn-off current stops heating, and simultaneously fan starting cools off heater, and the high-temperature residual heat that prevents heater continues heating and to break through setting value too many.Surpass plastic cement thawing technological temperature and can directly cause plastic cement physical and chemical parameter variation.This heat form electric conversion efficiency is low.
The roller temperature-controlling system structure more complicated of existing calender; Form by heat conduction oil type heat exchange station and conduction oil cyclic delivery system; The operation principle of heat exchange station is that heating of conduction oil heated by the resistance type heater heating, and cooling is the heat energy that water pump is delivered to water cooler exchange conduction oil; Conduction oil oil is all the time carried at pump and between heat exchange station and roller, is circulated, and whether heat or lower the temperature through electronic control system control conduction oil, thus the required temperature of assurance roller; Its shortcoming be roller temperature requirement through conduction oil back and forth heat exchange could realize that reaction is slow, exchange efficiency is low, heat exchange station unit cost is high, power consumption is big.
The utility model content
In order to overcome the deficiency of prior art, the utility model provides a kind of quick heating, thermal efficiency height, the flames of anger, no flue dust, no pernicious gas, and surrounding environment is not produced heat radiation, the plastic cement plate squeezing machine that working environment is friendly.
The utility model has adopted following technical scheme:
Plastic cement plate squeezing machine comprises plastic extruder and roller calender; It is characterized in that plastic extruder comprises iron and steel machine barrel, heat-insulation layer, solenoid, heat-insulation layer evenly is wrapped in the machine barrel outside; The solenoid uniform winding is in the heat-insulation layer outside, and the solenoid two ends connect high-frequency ac power.
Solenoid produces alternating magnetic field, makes machine barrel produce the alternation eddy current, and eddy current makes the iron molecule high speed random motion of iron and steel machine barrel, and molecule runs foul of each other, rubs and produces heat energy, i.e. machine barrel itself heating at a high speed voluntarily.Need not cooling blower, do not have the additional energy loss, quit work and no longer exist temperature rise inertia, temperature control is accurate, and excellent thermal insulation performance.
Preferably, said roller calender comprises solenoid, roller and cold water pipe, and cold water pipe prolongs and axially passes roller; Solenoid is a sandwich wound coil, keeps setpoint distance with the roller cylindrical shell, and the solenoid two ends connect high-frequency ac power.
Preferably, said solenoid is parallel with roller surface.
The roller uniform rotation, when needing heating, the solenoid energising is carried out eddy-current heating to roller; When needing cooling, cooling water directly cools off through the water channel of roller.Simple structure, with low cost, effect is remarkable.
Preferably, said iron and steel machine barrel and roller cylindrical shell are structural alloy steel 38CrMoAl.
Preferably, the frequency of said high-frequency ac power is 20kHz.
