the temperature control platform 400 is provided with a silicon controlled control chip 500, the silicon controlled control chip 500 is provided with a plurality of enabling pins, and the enabling pins are connected with the heating device 300 through flat cables.
Because the silicon controlled rectifier control chip 500 has accurate temperature control ability, and adopt the signal of telecommunication to transmit, based on the detection to heating current, silicon controlled rectifier control chip 500 can avoid the heat of heating device 300 to the influence of detecting the precision, consequently can the temperature of each heating device 300 of accurate control, it is even to make whole strip extrude chamber 100 go up everywhere temperature, owing to overcome the inhomogeneous problem of temperature, extrude chamber 100 and can do longer, correspondingly, the time that the PC material is extruded the liquefaction by screw rod 200 in extruding chamber 100 is longer, output quality is better.
Further, the middle part of the extrusion cavity 100 is provided with a vacuum dehumidifying device 600, the vacuum dehumidifying device 600 is attached to the heating device 300 at the corresponding position, and the air exhaust port of the vacuum dehumidifying device 600 is communicated to the extrusion cavity 100. Because the PC material is inevitably mixed with water vapor, in order to ensure the extrusion quality, the vacuum dehumidifying device 600 extracts the water in the extrusion cavity 100, and the quality of the liquid PC material is improved.
Further, the vacuum dehumidifying device 600 comprises a filter screen 610 and a drain pipe 620, wherein the filter screen 610 is arranged on the air exhaust port of the vacuum dehumidifying device 600, one end of the drain pipe 620 is connected with the inner cavity of the vacuum dehumidifying device 600, and the other end of the drain pipe is connected with an external drain. The PC material also contains some solid impurities, and because the vacuum dehumidifying device 600 sucks the liquid PC material, the large-molecule PC material can be blocked by the filter screen 610, and the small-molecule impurities are separated out, so that the quality of the liquid PC material is further improved.
Referring to fig. 3, further, the heating device 300 includes an annular heating resistor 310 and a thermocouple 320, the annular heating resistor 310 surrounds the outer wall of the extrusion chamber 100, a hot electrode of the thermocouple 320 contacts the annular heating resistor 310, and an output end of the thermocouple 320 is connected to a data pin of the temperature control console 400.
