Detailed description of the invention
As shown in Figure 1, safe mixer of the present utility model is provided with switch module, detection module, isolation module and driver module, when mixer work, can detect object near and through window, and the detection signal of generation is forced motor stalling through isolation module and driver module process.Its operation principle is as follows:
As closed air switch (QF) (positive safe DZ47-32 4P 32A elected as by air switch of the present utility model (QF)), be coupled to the detection module (2) of switch module (1), isolation module (3) and driver module (4) all power on, detection module (2) is not detecting that object is near also passing through clean window, (picking sensor of the present utility model (G) elects YNQ12-04L-2 DC24V as to picking sensor (G), output low level is effective) can not output signal, therefore one end that auxiliary reclay coil (KA) (positive safe JZX-22F (D) 2Z DC24V elected as by auxiliary reclay of the present utility model) is coupled to picking sensor (G) output is in high-impedance state, auxiliary reclay does not work, above-mentioned picking sensor (G), by Switching Power Supply (S-P), (Switching Power Supply of the present utility model (S-P) elects Delta PMC-24V025W1AA as to auxiliary reclay coil (KA), export 24V voltage) power.
Contactor coil (KM) one end is coupled to C phase firewire, the other end is coupled to zero line by being coupled to normally closed switch (KA-0), therefore contactor coil (KM) adhesive, according to the principle of electric magnetisation, coil two ends produce magnetic, impel the probe of contactor adhesive of carrying magnetic armature in drive circuit, therefore contactor (select according to the power of motor (8) by the model of contactor, mixer of the present utility model is for the production of poly-peace fat sole ink, motor (8) is 12.5KW, therefore the electric current that motor (8) normally runs is 25A, therefore positive safe CJX2-3210 elected as by A.C. contactor of the present utility model, the maximum electric current that can bear 32A) adhesive, after contactor, motor (8) is just electrified, electric current enters overtemperature relay (FR), and (electrothermal relay of the present utility model (FR) coordinates A.C. contactor to select, elect positive safe NR2-36/Z 23-32A as, maximum overcurrent can to 32A, use with A.C. contactor accessories), an overcurrent protection is carried out to motor (8), when when stall or overload appear in motor (8), electric current increases, electrothermal relay (FR) will disconnect, make motor (8) stall to reach the object of protection motor (8).
One side of picking sensor (G) is equidistantly provided with multiple infrared transmitting tube, the infrared receiving tube that another side has equal number to arrange equally accordingly, and each infrared transmitting tube to there being a corresponding infrared receiving tube, and is arranged on same straight line.When not having barrier between the infrared transmitting tube on same straight line, infrared receiving tube, the modulation signal (optical signal) that infrared transmitting tube sends can arrive infrared receiving tube smoothly.After infrared receiving tube receives modulation signal, corresponding internal circuit exports high level, and when there being barrier, the modulation signal (optical signal) that infrared transmitting tube sends can not arrive infrared receiving tube smoothly, at this moment this infrared receiving tube does not receive modulation signal, and corresponding internal circuit exports as low level.Infrared receiving tube can not be arrived smoothly near the modulation signal (optical signal) also sent through clean window infrared transmitting tube when there being object, at this moment this infrared receiving tube does not receive modulation signal, therefore the output of light curtain will output low level signal, one end due to auxiliary reclay coil (KA) is coupled to the 24V output of Switching Power Supply (S-P), one end is coupled to the output of picking sensor (G), therefore the two ends of auxiliary reclay coil (KA) form 24V voltage and adhesive, in like manner in the operation principle of contactor coil (KM), the normally closed switch (KA-0) being coupled to isolation module (3) is subject to the magnetic force of auxiliary reclay and disconnects, now contactor coil (KM) is with regard to power-off, therefore the contactor controlled by contactor coil (KM) disconnects, motor (8) stall because of dead electricity.
In the course of work described in above-mentioned, if the hand of staff stretches into accidentally when mixer not yet quits work in clean window, light curtain optical flame detector will detect signal and control motor (8) stall, thus reaches the object of protection staff.
In sum; the utility model by arranging switch module (1), detection module (2), isolation module (3) and driver module (4) on mixer; can detect that object passes through the signal of clean window, and control motor (8) stall, thus reach the object of protection staff.
The above is only preferred embodiment of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
