Abstract
The utility model discloses a but temperature measurement double screw extruder die head, but temperature measurement double screw extruder die head is inside to have the cavity, and this cavity is equipped with the opening of extruding the hole and being used for being connected that is used for the melt extrusion with the double screw extruder barrel, just the cavity still is equipped with the trompil that is used for inserting the thermocouple. The utility model provides a but temperature measurement double screw extruder die head has realized can real -time accuracy monitoring the fuse -element temperature in process of production through special die head design, can improve the accuracy and the repeatability of current production technology. Simultaneously, design simple structure, the cost is very nearly the same with the existing equipment, and can not produce any adverse effect to current technology.
Description
Technical field
The utility model relates to double screw extruder die head, and specifically one can thermometric double screw extruder die head.
Background technology
Double screw extruder is requisite equipment in plastics industry now, and the plastic particles more than 90% is produced by double screw extruder.Because the requirement of different plastic particles to processing temperature is widely different, in double-screw extruding pelletizing production technology, the control of temperature is seemed most important.
Current two kinds of methods are mainly contained to the monitor and forecast of temperature in double-screw extruding pelletizing production technology.First method is by being arranged on temperature sensor on machine barrel and heater carries out detection and control, this is the equipment that current all double screw extruders all can configure, this method disadvantage is that measured temperature and actual melt temperature exist greatest differences, in twin-screw extrusion production process, the heat of 70% to 80% is produced by the shearing friction of screw rod and resin, the heat of about 20% is only had to be provided by cylinder heating system, therefore, larger temperature difference is there is between melt and machine barrel, this temperature difference of actual measurement display is usually between 30 degrees Celsius to 50 degrees Celsius, second method carries out perforate on machine barrel, and thermocouple is inserted in machine barrel, thermocouple and melt are directly contacted and carries out temperature survey, as shown in Figure 1, this method directly can contact with melt due to thermocouple, the degree of accuracy comparatively first method increases, but, due to the existence of machine barrel inner screw, make thermocouple can not go deep into melt inside, only can contact on a small quantity with melt in the place near machine tube inner wall, therefore still there is the temperature difference of 20 degrees Celsius to 30 degrees Celsius in measuring tempeature and actual temperature.
Utility model content
The purpose of this utility model overcomes the deficiencies in the prior art, provides one can thermometric double screw extruder die head, and thermocouple can go deep into melt inside by this die head, measures accurately melt temperature, can not produce any impact to prilling.Meanwhile, this project organization is simple, and with low cost, applicability is wide.The utility model adopts following technical scheme in order to achieve the above object:
One can thermometric double screw extruder die head, described can have cavity by thermometric double screw extruder die internal, this cavity is provided with for the extrusion cavities of melt extrusion and the opening for being connected with double screw extruder machine barrel, and described cavity is also provided with the perforate for inserting thermocouple.
Preferably, described cavity inside diameter diminishes from described opening gradually to described extrusion cavities.
What the utility model provided can be designed by certain moduli head by thermometric double screw extruder die head, achieve in process of production can be real-time accurate measurements melt temperature, accuracy and the repeatability of existing production technology can be improved.Meanwhile, project organization is simple, cost and existing equipment very nearly the same, and any adverse effect can not be produced to existing technique.
Accompanying drawing explanation
Accompanying drawing described herein is used to provide further understanding of the present utility model, forms a application's part, does not form improper restriction of the present utility model, in the accompanying drawings:
Fig. 1 is prior art structural representation;
Fig. 2 is the utility model example structure schematic diagram.
Detailed description of the invention
Describe the utility model in detail below in conjunction with accompanying drawing and specific embodiment, be used for explaining the utility model in this illustrative examples of the present utility model and explanation, but not as to restriction of the present utility model.
Embodiment:
As shown in Figure 2, one can thermometric double screw extruder die head 1, described can have cavity 10 in thermometric double screw extruder die head 1 inside, lengthen along on screw rod 3 direction by die head of the prior art, this cavity is provided with for the extrusion cavities 11 of melt extrusion and the opening for being connected with double screw extruder machine barrel 2, be provided with screw rod 3 in machine barrel, and described cavity is also provided with the perforate for inserting thermocouple 4, thermocouple 4 can insert cavity structure from this tapping.
What above-described embodiment scheme provided can thermometric double screw extruder die head 1, and when double screw extruder works, can be full of melt in cavity 10, therefore thermocouple 4 fully can contact with melt, accurately measures the actual temperature of melt.
As the improvement of above-described embodiment scheme, the internal diameter of described cavity 10 diminishes from described opening gradually to described extrusion cavities 11, get final product the inwall of thermometric double screw extruder die head 1 for being obliquely installed, melt overstand and degrading in cavity 10 can be avoided, any impact can not be produced on existing production technology.
Above the technical scheme that the utility model embodiment provides is described in detail, apply specific case herein to set forth the principle of the utility model embodiment and embodiment, the explanation of above embodiment is only applicable to the principle helping to understand the utility model embodiment; Meanwhile, for one of ordinary skill in the art, according to the utility model embodiment, detailed description of the invention and range of application all will change, and in sum, this description should not be construed as restriction of the present utility model.
