Description
Technical field
This utility model relates to a kind of moulding equipment of rubber, is used for the shaping to runway product, more specifically, it relates to a kind of rubber hot press.
Background technology
Hot press be a kind of by heat parts tin plating for two scaling powders the most first-class to being enough to make the temperature of melts soldering tin, flowing, after solidification, between part with scolding tin, form a permanent electricapparatus be connected equipment.Answering different product, programming rate can be chosen from.Titanium alloy pressure head guarantees temperature-averaging, heats up quickly and speciality in service life.Pressure head uses the adjustable design of level especially, average to guarantee assembly pressurized.Temperature NC postprocessing, clear precision.Have digital pressure recorder, predeterminable pressure limit.Particularly in the heat pressure forming process of rubber, required temperature is higher, so when hot pressing, temperature not yet returns to original temperature, and if now have human contact's pressure head, then be highly susceptible to impact, cause the direct scalded skin of high temperature.
Utility model content
The deficiency existed for prior art, the purpose of this utility model is to provide one can detect, when pressure head temperature is too high, a kind of rubber hot press that human body is the most close and reports to the police.
For achieving the above object, this utility model provides following technical scheme: a kind of rubber hot press, including pressure head, described pressure head is provided with warning circuit, described warning circuit includes warming module, is used for detecting pressure head temperature, and the output enabling signal when pressure head temperature is more than a preset value；Pyroelectricity module, is controlled by enabling signal work, is used for detecting near pressure head biological thermal source, have near pressure head biological thermal source close to time, outputting alarm signal；Alarm module, is coupled to pyroelectricity module, is used for reminding user pressure head temperature too high.
The power being primarily due to pyroelectricity module is higher, so being not suitable for working long hours, and when warming module senses, pyroelectricity module just can be made to work, to reduce the output of pyroelectricity module, and when human body is near pressure head, controlling alarm module by pyroelectricity module outputting alarm signal reminds user now temperature too high, should not directly contact pressure head.
Further: described warming module includes temperature sensor, it is used for detecting pressure head temperature and exporting sampled voltage；Reference cell, is used for providing reference voltage；Comparing unit, is coupled to temperature sensor and reference cell, when sampled voltage is more than reference voltage, exports comparison signal；Performance element, is coupled to comparing unit, when receiving comparison signal, exports shielded signal.It is independently arranged by each module, so that easy to maintenance, and reaction precision is higher, principle is simple, and circuit expansibility is higher.
Further: described reference cell includes the first resistance, the second resistance and the 3rd resistance being arranged in series, the node output reference voltage that described first resistance and the second resistance couple.Make reference voltage stable, it is ensured that precision.
Further: described 3rd resistance is set to adjustable resistance.Make reference voltage adjustable, namely can regulate the temperature that pyroelectricity is started working according to demand.
Further: described pyroelectricity module includes housing, optical filter, field effect transistor and pyroelectricity element, described housing is provided with through hole, described optical filter is connected in described through hole, described field effect transistor and pyroelectricity element are positioned at the enclosure interior of described pyroelectric infrared sensor, described pyroelectricity element is connected between the grid of described field effect transistor and ground end, the drain electrode of described field effect transistor is connected to alarm module, and its source electrode is connected to high level.The Main Function of optical filter is only to allow wavelength infrared ray (Infrared wavelength that human body sends) about 10 μm to pass through, and light, sunlight and other radiation is filtered, with the interference that suppression is extraneous.Infrared induction source is generally made up of two pyroelectricity elements in series or in parallel, the electrode of the two pyroelectricity element is contrary, ambient background radiation almost has identical effect to two pyroelectricity elements so that it is the pyroelectric effect of generation is cancelled out each other, and output signal is close to zero.In once having people's intrusion detection region, human infrared radiation is focused on by partial mirror, and is received by pyroelectricity element, owing to angle is different, the heat that two panels pyroelectricity element receives is different, and pyroelectricity energy is the most different, can not be completely counterbalanced by, after treated processing of circuit, export control signal.Pyroelectric effect is similar to piezoelectric effect, refers to cause the phenomenon of plane of crystal electric charge due to the change of temperature.Pyroelectric infrared sensor is made up of ceramic oxide or piezolectric crystal unit, electrode is made on two surfaces of element, when in the range of Sensor monitoring, temperature has the change of △ T, pyroelectric effect can produce electric charge △ Q on two electrodes, produces a faint voltage △ V the most between electrodes.Owing to its output impedance is high, a field effect transistor is had to carry out impedance transformation in the sensor.Produced by pyroelectric effect, electric charge △ Q can be combined by the ion in air and disappear, and i.e. when ambient temperature-stable is constant, △ T=O, sensor is without output.Human body or the bigger animal of volume have constant body temperature, general at 37 degree, so the infrared ray about specific wavelength 10 μm can be sent, when human body enters detection zone, because human body temperature and ambient temperature have difference, infrared ray about 10 μm of human-body emitting gathers on infrared induction source (pyroelectricity element) after being strengthened by Fresnel lens optical filter, infrared induction source will lose charge balance when receiving human infrared radiation, outwards discharge electric charge, and then produce △ T and △ T circuit to the periphery is exported, subsequent conditioning circuit just can produce warning signal after processing after testing.
Further: the drain electrode of described field effect transistor is provided with EMI electric capacity with ground end.On the one hand the magnitude of voltage that drain electrode export can be made close to constant, and it exports the impact being susceptible to magnetic disturbance.
Further: described fet gate is provided with biasing resistor with ground end.It is current signal owing to electrocaloric effect creates signal, so arranging a resistance by the grid of scene effect pipe with ground end, current signal can be converted into voltage signal, and the threshold value of its conducting can be regulated by the resistance of regulation biasing resistor, namely regulate the sensitivity of pyroelectric infrared sensor, simple in construction, it is easy to accomplish.
Further: described alarm module includes buzzer and display lamp.User is made to be more easy to find dangerous situation.
By using technique scheme, the power being primarily due to pyroelectricity module is higher, so being not suitable for working long hours, and when warming module senses, pyroelectricity module just can be made to work, to reduce the output of pyroelectricity module, and when human body is near pressure head, controlling alarm module by pyroelectricity module outputting alarm signal reminds user now temperature too high, should not directly contact pressure head.
