Abstract
A temperature control system of a double-screw extruder comprises a temperature sensor, a processor, a control switch and a controller, wherein the processor comprises a processing chip and a counter; the processing chip is connected with the control switch, the controller and the temperature sensor respectively; the control switch is connected with a main switch of the double-screw extruder in series; the controller is provided with a plurality of control buttons; and the temperature sensor is installed on a heating device of a double-screw extruder body. The temperature control system has a simple structure, can control the preheating time of various materials to be the optimum according to technical requirements strictly, can lock the extruder in the preheating period, so that the energy consumption can be reduced and the working efficiency can be improved.
Description
Technical field
The utility model relates to plant equipment manufacturing technology field, especially a kind of temperature control system of double screw extruder.
Background technology
Double screw extruder has very excellent processing characteristics as a kind of general plastic master batch manufacturing equipment in master batch productions such as PE, PP, ABS, PA.Especially the manufacturing of inserts has changed the shortcoming of in the past mediating the batch production of granulation again.
Necessary process when preheating is double screw extruder work is by a plurality of heaters that are installed on the double screw extruder fuselage extruder to be heated.In extrusion molding material process, preheating can be eliminated the high temperature head, and the greatly different temperature difference that forms when contacting with plastic cement at the die orifice place is avoided the fluctuation of plastic cement temperature and caused the fluctuation of extrusion pressure, thereby stablize extrusion capacity, and quality is extruded in assurance.
Existing double screw extruder in use, many dependence operators judge the preheating situation, whether decision starts extruder, because each material difference in extruder, also be not quite similar required preheating time, the operator is subjected to the restriction of its experience, all is controlled at best point the very difficult preheating time that will at every turn operate.If preheating time is long, then can seriously reduce the waste of quality of the operating efficiency of extruder and extruded product and the waste of the energy.
The utility model content
The purpose of this utility model is to provide a kind of double screw extruder temperature control system that can control preheat temperature and locking automatically, start extruder.
The technical solution of the utility model is: a kind of temperature control system of double screw extruder, comprise temperature sensor, processor, gauge tap, controller, and processor is made up of process chip, counter; Described process chip links to each other with gauge tap, controller, temperature sensor respectively; Gauge tap is connected in series with the main switch of double screw extruder; Controller is provided with a plurality of control buttons; Temperature sensor is installed on the heater that is arranged on the double screw extruder fuselage.
Operation principle of the present utility model is: when double screw extruder needs work, connection is arranged at the heater switch on the double screw extruder fuselage, according to the material of putting into extruder, pressing corresponding control button on the controller, this moment, controller sent to process chip in the processor with command signal, process chip is called corresponding control program, gauge tap disconnects, reach double screw extruder locking between warming up period, temperature sensor sends to process chip with temperature signal, when temperature reaches the design temperature of control program, process chip control timer is started working, and through the timer timing, confirms to reach the preheating time that sets, process chip control gauge tap is connected, and finishes preheating.
The utility model is simple in structure, can be strict by technological requirement preheating time of various materials be controlled at best point, and locks extruder between warming up period, has promptly reduced energy resource consumption, has improved operating efficiency again.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model, also is that summary is with scheming.
Each label is respectively among the figure: (1) (2) (3) temperature sensor; (4) processor; (5) gauge tap; (6) controller; (7) process chip; (8) counter.
The specific embodiment
Now the utility model is described in further detail in conjunction with the accompanying drawings.
Processor 4 is made up of process chip 7, counter 8; Described process chip 7 links to each other with gauge tap 5, controller 6, temperature sensor 1,2,3 respectively; Gauge tap 5 is connected in series with the main switch of double screw extruder; Controller 6 is provided with a plurality of control buttons; Temperature sensor 1,2,3 is installed on the heater that is arranged on the double screw extruder fuselage.
