Role, and there are many type of extruder, and principle is also not quite similar, but is required for the control to temperature in production process, especially
It is multihead extruder, and in summer, temperature is inherently very high, during extruder production run, since extruder is in high speed
A large amount of frictional heat and shear heat are generated when operating can destroy thermal balance, cause temperature to rise very high, have exceeded technological temperature, give
Product quality brings prodigious influence, and resulting even in production can not be normally carried out.It is very low in winter temperature, extruder head due to
Temperature is low, can not ensure that the extruded velocity of extruder bull synchronizes, also can not normally be produced.For this reason, it may be necessary to design one kind
Thermostat effectively controls the stabilization of the temperature of extruder head.
Invention content
Technical problem solved by the invention is to provide a kind of circulation constant temperature water installations of extruder head, can be effectively
The temperature in cross-head is controlled, so that it is kept temperature constant state, ensures the reliability of production run.
In order to solve the above technical problems, the present invention adopts the following technical scheme that：
A kind of circulation constant temperature water installations of extruder head, including cross-head and the perseverance that is located on the cross-head
Warm device, it is characterised in that：The thermostat is the hollow nut structure with inlet and outlet pipes connector, the Inlet and outlet water
Pipe fitting is connect with constant temperature water system, and the constant temperature water system is by water pump group, water feeding tank, recovery tank, pressure sensor, temperature
Sensor and control system composition, the water pump group are connected between the water feeding tank and recovery tank, and the temperature passes
Sensor is separately mounted in water feeding tank and recovery tank, and the pressure sensor is mounted in water feeding tank, the control system
Including PLC controller, temperature-adjusting heating device is equipped in the water feeding tank, the water pump component is main pump group, auxiliary pump group
With spare pump group, the water feeding tank is the auto-pneumatic cylinder of a diameter of 600mm-1200mm, is equipped with and overflows at the top of the recovery tank
Head piece, bottom are equipped with sewage draining exit.
Compared with prior art, beneficial effects of the present invention are：
A kind of circulation constant temperature water installations of extruder head of the present invention compared with prior art, by installing one in extruder head
The thermostat of a hollow nut structure connect the thermostatic control completed to extruder head, wherein constant temperature water system with constant temperature water system
System is controlled using PLC controller, whole process high degree of automation, is manipulated simple, better reliability, can also be reduced cost, carry
High efficiency.
Description of the drawings
Fig. 1 is thermostatted water system structure diagram of the present invention；
Fig. 2 is thermostat structural schematic diagram of the present invention.
Specific implementation mode
Shown in attached drawing 1-2, a kind of circulation constant temperature water installations of extruder head, including cross-head 1 and it is located at institute
The thermostat 2 on cross-head 1 is stated, the thermostat 2 is the hollow nut knot with inlet and outlet pipes connector 2-1
Structure, the inlet and outlet pipes connector 2-1 are connect with constant temperature water system 3, and the constant temperature water system 3 is by water pump group 3-1, water feeding tank
3-2, recovery tank 3-3, pressure sensor 3-4, temperature sensor 3-5 and control system 3-6 compositions, the water pump group 3-1 connect
It is connected between the water feeding tank 3-2 and recovery tank 3-3, the temperature sensor 3-5 is separately mounted to water feeding tank 3-2 and returns
In water tank 3-3, the pressure sensor 3-4 is mounted in water feeding tank 3-2, and the control system 3-6 includes PLC controller

Overflow port, bottom are equipped with sewage draining exit.
Specifically used mode, by the return water of water outlet the interface tube 3-8 and recovery tank 3-3 of the water feeding tank 3-2 of constant temperature water system 3
Interface tube 3-9 is connected with the inlet and outlet pipes connector 2-1 of thermostat 2, is arranged in the PLC controller 3-7 of control system 3-6
Good technological parameter（The temperature and pressure of thermostatted water）.Constant temperature water system 3 is opened in advance when extruder does not work, at this point, water pump
Group 3-1 starts, and the water inside water feeding tank 3-2 is flowed into thermostat 2 by pressure and followed to recovery tank 3-3 strokes in return water
Bad, when the temperature of the temperature sensor 3-5 detections inside water feeding tank 3-2 is less than setting value, PLC controller 3-7 sends out instruction
The temperature-adjusting heating device for starting water feeding tank 3-2 is heated and is stopped after reaching process set value, by the cycle of water, when setting
When the temperature of the temperature sensor 3-5 detections of recovery tank 3-3 meets technological parameter, extruder can be started at this time and given birth to
Production；Extruder will produce heat in process of production, when the temperature of the temperature sensor 3-5 detections of recovery tank 3-3 is higher than technique
When parameter, at this time PLC controller 3-7 send out instruction stop temperature-adjusting heating device in water feeding tank 3-2 and by tap water or
The water of cooling tower cooling cools down.
A kind of circulation constant temperature water installations of extruder head of the present invention compared with prior art, by installing one in extruder head
The thermostat of a hollow nut structure connect the thermostatic control completed to extruder head, wherein constant temperature water system with constant temperature water system
System is controlled using PLC controller, whole process high degree of automation, is manipulated simple, better reliability, can also be reduced cost, carry
