Description of the drawings
Fig. 1 is a kind of structural schematic diagram of the positive-displacement machines dual probe temperature control device of embodiment of the utility model.
Specific implementation mode
The utility model is described in further detail below by specific implementation mode combination attached drawing.
The utility model embodiment provides a kind of positive-displacement machines dual probe temperature control device, which is used to be mounted on screen pressure
On machine, there is screen positive-displacement machines thermal head 1 as shown in Figure 1, thermal head 1 to be connected with pulse by dedicated power supply power supply, power supply
Power supply signal is converted to the power supply signal needed for thermal head 1 by transformer, pulse transformer.Pulse transformer then with screen pressure
PLC controller inside machine is connected, and PLC controller is responsible for the coordination control of entire screen positive-displacement machines.
As shown in Figure 1, including thermal head 1,1 plate-like structure of thermal head is formed in the bottom of thermal head 1 and is used for and winding displacement
The contact head 11 of contact, power supply load on thermal head 1 so that thermal head 1 generates heat, and contact head 11 corresponds to heating, with the company of waiting for
The winding displacement contact connect so that connected after winding displacement hot melt.Temperature sensor 2, temperature sensor 2 are fixed on the contact head 11
It can detect the temperature of contact head 11.Thermal sleeve 3 is fixed on the thermal head 1, one end of thermal sleeve 3 is close to temperature
Sensor 2 is spent, for the other end then far from thermal head 1, thermal sleeve 3 can select hose made of heat-barrier material.One end of conducting wire 4
It is connected across the thermal sleeve 3 and with temperature sensor 2, the other end of conducting wire 4 is connected with terminal box 5, and terminal box 5 is used for will
The signal that temperature sensor 2 exports carries out level conversion, and then passes through the PLC controller phase of two leading-out terminals 51 and positive-displacement machines
Even.The temperature value that PLC can be fed back according to temperature sensor 2, controls voltage regulating module, and changing pulse transformer output voltage makes heat
The temperature of pressure head 1 is kept constant, and is not in higher or relatively low temperature, is promoted the stability of thermal head 1, is extended it and use the longevity
Life.
Meanwhile conducting wire 4 has thermal sleeve 3 to be protected, and can prevent the high temperature on thermal head 1 from conducting wire 4 fusing, and ensures
The steady operation of positive-displacement machines dual probe temperature control device.
In one embodiment, as shown in Figure 1, there are two the temperature sensor 2 sets, between two temperature sensors 2
It is spaced a predetermined distance, can be located separately the both ends of contact head 11, multimetering is carried out with butt contact 11, promotes the accurate of measurement
