The specific embodiment
Below in conjunction with accompanying drawing, embodiment is described in further detail the present invention.
Bar shaped flatiron, formed by handle portion and heating part, as shown in Figure 2, Figure 3, Figure 4, handle portion comprises temperature regulating switch 1, handle 2, flatiron arm 3, socket 4, heating part comprises insulation frame 5, heat-barrier material frame 6, electrothermal tube 7, heat transfer plate 8, heat-barrier material cover 9, it is characterized in that: in flatiron handle 2, have electric heating temperature control plate, have temperature regulating switch 1 on flatiron handle 2, there is socket 4 flatiron arm 3 sides; Flatiron arm 3 is arranged on insulation frame 5; Insulation frame 5 cross sections are inverted U-shaped that Open Side Down, the interior installation heat-barrier material of insulation frame 5 frame 6, heat-barrier material frame 6 cross sections are inverted U-shaped that Open Side Down, the interior installation electrothermal tube 7 of heat-barrier material frame 6, insulation frame is installed heat transfer plate 85 times, heat transfer plate 8 lower surfaces have two del fins, and heat transfer plate is installed heat-barrier material cover 9 for 8 times, and it is U-shaped that heat-barrier material overlaps 9 cross sections.
Electric control principle
Circuit theory diagrams as shown in Figure 5.
This temperature controller is used as IGCT VTH the switch element of heater EH, set temperature control triggering electric circuit RT, R3, VT1, VT2 and RP etc. on gate circuit transistor gate G.These circuits for triggering provide control circuit electric current after by R2 step-down, and light emitting diode VL1 and VL2 contrary by two polarity and that connect carry out AC voltage-stabilizing, provide the alternating voltage that is about 2.3V for VTl and VI and negative temperature coefficient thermistor.
Circuit is connected the initial stage, and because temperature is low, negative temperature coefficient thermistor resistance value is large, thermal resistor two ends alternating voltage VRT > 0.6V, while exchanging positive half cycle, PNP transistor VTl conducting, collector current triggers IGCT VTH conducting through VD1.Exchange when negative half period, NPN transistor VT2 conducting, collector current is flowed out through VD2 to transistor VT2 by the G utmost point of VTH, negative sense triggering IGCT VTH conducting.Temperature after heating raises gradually, and negative temperature coefficient thermistor RT resistance value also reduces gradually, and regulator potentiometer RP can make vRT < 0.6V, makes the triggering cut-off of VT1 to IGCT VTH, stops heating.Stop temperature after heating and drop to lower than controlling when temperature, more than the terminal voltage of thermal resistor goes back up to 0.6V, VT1 and VT2 make IGCT conducting again, start heating.Said process constantly repeats, and temperature is controlled to constant temperature point upper, realizes thermostatic control.
Screen pack preformed seam implementation process
Determine silk netting by size, as shown in Figure 6.
Fan-shaped silk netting one end is enclosed within the locating pin of the outside longitudinal arrangement of Fig. 7 screen pack pre-shaping device, the other end is walked around filter screen pre-shaping device outside one week, be enclosed within the locating pin of the outside longitudinal arrangement of screen pack pre-shaping device, 90 degree were rolled in upper end, were fixed on the locating pin at top.
Bar shaped flatiron temperature regulating switch 1 is transferred to suitable temperature, when temperature reaches after seam temperature, flatiron is pressed in to the silk netting overlapping of screen pack pre-shaping device side, slightly press and mention, by overlapping silk netting seam.
