The temperature sensors in the intelligent EVA rubber heating pipeline provided by the invention are used for acquiring temperature signals, and the central processing unit is used for automatically controlling power of the heating sheet depending on temperature, so as to avoid local overheating. And the intelligent EVA rubber heating pipeline, compared to a conventional way, is obvious in energy conservation.
Description
Technical field
The present invention relates to a kind of water back, especially a kind of intelligent EVA glue water back, belongs to macromolecular material manufacturing technology field.
Background technology
In existing EVA glued membrane processing procedure, all adopt micelle is pressed into the then technique of heat fused of pipeline.But, because EVA glue is hot non-conductor, so heating process may cause hot-spot.Extremely affect the quality of glued membrane.
General countermeasure is at present, at water back, loads onto cooling device outward, if there is hot-spot, carries out cooling.But such mode weak effect is very huge to expending of the energy simultaneously.
Summary of the invention
The technical problem that the present invention solves is: propose a kind of avoid occurring hot-spot and then comparatively energy-conservation EVA glue water back.
In order to solve the problems of the technologies described above, the technical scheme that the present invention proposes is: a kind of intelligent EVA glue water back, comprises the pipeline being wrapped in heat-insulation layer and the electric heating sheets that is located at pipeline outside; In described pipeline, be evenly interval with temperature sensor; The port of export of described pipeline is provided with flowmeter; The data input pin that is connected to a central processing unit after described temperature sensor output series connection mould/number conversion module, described flowmeter is connected to the signal input part of described central processing unit; The output port of described central processing unit is connected with display; 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.
The present invention further improves and is: 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: intelligent EVA glue water back provided by the invention, and use traffic meter collection outlet load, central processing unit, according to the corresponding whole heating power of whole heating plates of adjusting of the height of these data, is avoided waste.Pipe interior is evenly provided with temperature sensor, by temperature sensor collecting temperature signal, is automatically controlled the power of the heating plate of correspondence position by central processing unit according to temperature, guarantees that part is not overheated.Such water back is compared to traditional approach, obviously energy-conservation.
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-heat-insulation layer, 2-pipeline, 3-electric heating sheets, 4-temperature sensor, 5-flowmeter.
The specific embodiment
Embodiment
A kind of intelligent EVA glue water back of the present embodiment, comprises the pipeline 2 being wrapped in heat-insulation layer 1 and the electric heating sheets 3 that is located at pipeline 2 outsides; The interior temperature sensor 4 that is evenly interval with of pipeline 2; The port of export of pipeline 2 is provided with flowmeter 5; The data input pin that is connected to a central processing unit after temperature sensor 4 output series connection mould/number conversion modules, flowmeter 5 is connected to the signal input part of central processing unit; The output port of central processing unit is connected with display; Electric heating sheets 3 regulates power by controllable silicon, and controllable silicon is controlled by central processing unit.
Meanwhile, for the expansion of practical function: the PORT COM of central processing unit is connected with 485 communication modules.
During work, pipeline is injected into method, apparatus in the past and pushes the EVA micelle of coming, and electric heating sheets 3 starts heating with full power.Meanwhile, central processing unit is collected the temperature value that each temperature sensor 4 transmits, and shows on display.If the temperature at certain temperature sensor 4 place reaches normal temperature, close down electric heating sheets 3 herein, it is overheated to avoid occurring.
When the temperature at certain the temperature sensor 4 place temperature that is near the mark, lower than normal temperature 10%, the power of controlling electric heating sheets 3 herein reduces by 50%, and it is overheated to prevent in advance.
Central processing unit, except electric heating sheets 3 being adjusted according to the Temperature numerical of temperature sensor, gathers the flow of pipeline 2 outlets simultaneously, and flow is less, and power output is less.If flow is lower than 20% of the standard setting in advance, the overall power of electric heating sheets 3 reduces by 5%, and when flow is lower than setting in advance 50% of standard, overall power reduces by 10%, to reach energy-conservation object.
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.
