Abstract
The invention relates to an EVA (ethylene-vinyl acetate copolymer) adhesive temperature control and heating extruder, belonging to the technical field of polymer material preparation. The EVA adhesive temperature control and heating extruder comprises a cylinder and a screw arranged in the cylinder and driven by a motor, wherein electric heating plates are uniformly stuck to the outer wall of the cylinder; temperature sensors are uniformly arranged in the space keeping away from the screw in the cylinder at intervals; the output ends of the temperature sensors are sequentially connected with an analog/digital conversion module and a central processing unit (CPU) in series; the electric heating plates are controlled by the CPU. The EVA adhesive temperature control and heating extruder provided by the invention has the beneficial effects that the electric heating plates are arranged on the outer wall of the cylinder and are used for heating and maintaining the temperatures of EVA adhesives in the cylinder; the temperature sensors are also arranged in the cylinder and are used for acquiring temperature signals; the CPU is used for automatically controlling the powers of the heating plates according to the temperatures to prevent overheating.
Description
Technical field
The present invention relates to a kind of EVA glue temperature control heating extrusion device, belong to macromolecular material manufacturing technology field.
Background technology
In existing EVA glued membrane processing procedure, all adopt micelle is pressed into pipeline, additive package, heat fused then, then extruded by extruder, then by pressure roller press mold cooling forming.But existing extruder majority does not have heating function, or has heating function, still do not there is the function of temperature adjusting.
Summary of the invention
The technical problem that the present invention solves is: propose a kind of EVA glue heating extrusion device with heating temperature-adjustable.
In order to solve the problems of the technologies described above, the technical scheme that the present invention proposes is: a kind of EVA glue temperature control heating extrusion device, comprise machine barrel and be located in machine barrel by motor-driven screw rod; On described machine barrel outer wall, be evenly pasted with electric heating sheets; In described machine barrel, avoid being evenly interval with temperature sensor in the space of described screw rod; Described temperature sensor output is in series with mould/number conversion module and central processing unit successively; Described electric heating sheets is controlled by described central processing unit.
The present invention further improves: the Wheatstone bridge that described temperature sensor is comprised of a thermistor and three fixed value resistance forms.The present invention adopt Wheatstone bridge with guarantee to the test of temperature precisely.
Further improve and be: between described Wheatstone bridge and described mould/number conversion module, be in series with successively difference amplifier and low pass filter.By the amplification of difference amplifier and the filtering of wave filter, further guarantee the accuracy of test.
Expansion for practical function: the PORT COM of described central processing unit is connected with 485 communication modules.
The beneficial effect that the present invention brings is: EVA glue temperature control heating extrusion device provided by the invention, is provided with electric heating sheets at machine barrel outer wall, in order to heat and to maintain the temperature of the EVA glue in machine barrel.Machine barrel inside is also provided with temperature sensor, by temperature sensor collecting temperature signal, is automatically controlled the power of heating plate by central processing unit according to temperature, and it is overheated to prevent.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, to of the present invention, be described further.
Fig. 1 is the structural representation of a preferred embodiment of the invention.
Number in the figure is schematically as follows: 1-machine barrel, 2-screw rod, 3-electric heating sheets, 4-temperature sensor.
The specific embodiment
Embodiment
A kind of EVA glue temperature control heating extrusion device of the present embodiment, as shown in Figure 1, comprise machine barrel 1 and be located in machine barrel 1 by motor-driven screw rod 2; On machine barrel 1 outer wall, be evenly pasted with electric heating sheets 3; In machine barrel 1, avoid being evenly interval with temperature sensor 4 in the space of screw rod 2; Temperature sensor 4 outputs are in series with mould/number conversion module and central processing unit successively; Electric heating sheets 3 is controlled by central processing unit.
Temperature sensor 4 in the present embodiment adopts by a thermistor and three wheatstone bridge circuits that fixed value resistance forms.In order to make temperature test more accurate, between Wheatstone bridge and mould/number conversion module, be in series with successively difference amplifier and low pass filter.By the amplification of difference amplifier and the filtering of wave filter, make signal more accurate.
Meanwhile, for the expansion of practical function: the PORT COM of central processing unit is connected with 485 communication modules.
During work, machine barrel 1 upper opening connects water back, and the EVA glue melting through water back is injected into, and then by motor-driven screw rod, is advanced, and EVA glue is extruded into chill roll from lower opening.In order to prevent that EVA glue from lowering the temperature in extrusion device, electric heating sheets 3 is in order to maintain its temperature, the temperature of inner temperature sensor 4 monitoring EVA glue simultaneously, if temperature is too low, by the pwm signal of central processing unit, controlling electric heating sheets 4 increases power heatings.If excess Temperature, reduces power heating.With this, realize EVA glue whole process and maintain its temperature.
The present invention is not limited to above-described embodiment, and all employings are equal to replaces the technical scheme forming, and all drops in the protection domain of requirement of the present invention.
