Alarm device of medical health materials casting compound machine

Abstract

The invention discloses an alarm device of a casting compound machine of medical supply. The alarm device comprises a voltage signal collection circuit 1, a voltage signal collection circuit 2, a comparison attenuation circuit and an alarm circuit; the voltage signal collection circuit 1 and the voltage signal collection circuit 2 collect voltage signals in two different positions in a power supply output channel during work of the casting compound machine of medical supply respectively, the comparison attenuation circuit uses a comparator AR1 to compare and process signals input by the voltage signal collection circuit 1 and the voltage signal collection circuit 2, one path of signals output by the comparator AR1 is input to an operational amplifier AR2 for in-phase amplification, the other path of signals is attenuated by an attenuation circuit composed of a variable resistor R21 and resistors R4 and R17, and when the power supply output voltage is abnormal during work of the castingcompound machine, an alarm LS1 works to raise the alarm. The power supply voltage during work of the casting compound machine of the medical supply can be detected in real time, and alarm can be raised timely when the voltage is abnormal.

Description

technical field [0001] The invention relates to the technical field of power supply alarms, in particular to an alarm device for a casting composite machine for medical hygiene materials. Background technique [0002] The medical and sanitary materials casting compound machine can be used to make disposable surgical gowns, isolation gowns, surgical drapes, surgical drapes, examination pads, waterproof pads, dental bibs, shoe covers, PE gowns, tapes, and are used in the processing and manufacturing of medical and sanitary materials. Occupying an important "seat", the medical and sanitary material tape casting compound machine integrates discharging, drying, surface treatment, compounding, trimming, suction and winding, and is multifunctional. In one factory, medical and sanitary The material casting compound machine does not work alone, but also requires the cooperation of other equipment, so it is also controlled by the overall control terminal of the factory. However, the l...

[0002] The medical and sanitary materials casting compound machine can be used to make disposable surgical gowns, isolation gowns, surgical drapes, surgical drapes, examination pads, waterproof pads, dental bibs, shoe covers, PE gowns, tapes, and are used in the processing and manufacturing of medical and sanitary materials. Occupying an important "seat", the medical and sanitary material tape casting compound machine integrates discharging, drying, surface treatment, compounding, trimming, suction and winding, and is multifunctional. In one factory, medical and sanitary The material casting compound machine does not work alone, but also requires the cooperation of other equipment, so it is also controlled by the overall control terminal of the factory. However, the long-term work of the medical health material casting compound machine will cause its working voltage to be unstable, and real-time detection is required. The output voltage of the power supply when the sanitary material tape-laying compound machine is working can alarm in time when the voltage is abnormal, but in actual work, the voltage signals at different positions on the output channel of the power supply will be different when the medical sanitary material tape-laying compound machine is working , the single-point voltage signal acquisition on the output channel of the power supply when the medical and health material casting composite machine is working, there will be a certain detection signal error
