Description
Technical field
The utility model relates to flour finishing technology field, vibroswitch when specifically a grow wheat charging detects and comprise the delay circuit of this vibroswitch.
background technology
In flour processing technical field, it is the important evidence judging whether system normally works that material in pipeline detects, be control system work whether, realize important parameter that is energy-efficient and early warning, therefore accurately detect particularly important.In order to cost-saving, consider technology maturity and complexity, traditional pipeline material checkout gear generally have employed reflected infrared sensors as signal acquisition terminal simultaneously, and realizes detecting by arranging a glass window at duct wall.But the material transfer canal due to flour processing place is different from the detection in other field, by the impact of more dust in pipeline, easily causes glass visibility to reduce in use for some time, and then cause transducer to judge by accident.
Summary of the invention
For overcoming the deficiencies in the prior art, goal of the invention of the present utility model is the delay circuit providing a kind of vibroswitch and comprise this vibroswitch, to solve the problem of the frequent false alarm of transducer.
For achieving the above object, the extraction electrode one of the utility model vibroswitch S1 is fixed on non-metal shell, and extraction electrode one is connected with vibrations spring, and vibrations spring has moving contact, and connecting rod is fixed on moving contact, and the afterbody of connecting rod is connected with jolting plate; Extraction electrode two is fixed on non-metal shell, and extraction electrode two is connected with metal inner cavity, and metal inner cavity is connected with fixed contact; With for vibration switch S1 being fixed on holding screw one in pipeline and holding screw two on non-metal shell; At the tip side of non-metal shell with rubber dust cap; Flour in pipeline or wheat impact endurance test shock plate, jolting plate drives moving contact and the vibrations of vibrations spring, and produce Elastic Contact between moving contact and fixed contact, extraction electrode one connects positive source, and extraction electrode two produces pulse signal.
Described vibroswitch S1 seals in circuit, and electric capacity C1 and resistance R1 parallel connection in circuit, form the delay for eliminating the signal-wobble circuit.
The utility model compared with prior art, has the following advantages:
(1) adopt vibroswitch to substitute traditional infrared sensor, avoid the misoperation that the impact due to dust causes.
(2) install simple, only need to open on pipeline circular hole both can, can from external stability screw.
(3) structure is simple, with low cost.

Fig. 2 is the internal structure profile of the utility model vibroswitch.
Fig. 3 is the wiring schematic diagram of the utility model and available circuit.
Embodiment
As shown in Figure 1 and Figure 2, the extraction electrode 1 of the utility model vibroswitch is fixed on non-metal shell 5, and extraction electrode 1 is connected with vibrations spring 12, and vibrations spring 12 has moving contact 10, connecting rod 7 is fixed on moving contact 10, and the afterbody of connecting rod 7 is connected with jolting plate 8.Extraction electrode 22 is fixed on non-metal shell 5, and extraction electrode 22 is connected with metal inner cavity 9, and metal inner cavity 9 is connected with fixed contact 11.Non-metal shell 5 there are holding screw 1 and holding screw 24, for being fixed in pipeline by vibration switch.In order to prevent dust from entering gap between moving contact 10 and fixed contact 11, be designed with a rubber dust cap 6 at the tip side of non-metal shell 5.
When the flour in pipeline or wheat impact endurance test shock plate 8, under the connection function of connecting rod 7, jolting plate 8 drives moving contact 10 and vibrations spring 12 to shake together.Elastic Contact is produced between moving contact 10 and fixed contact 11.When extraction electrode 1 connects positive source, pulse signal will be produced on extraction electrode 22.
As shown in Figure 3, due to vibroswitch S1 output is pulse signal, and checks in pipeline whether have material it is desirable that switching signal, in order to realize signal conversion, the utility model also comprises the delay for eliminating the signal-wobble circuit, and vibroswitch S1 seals in circuit, and electric capacity C1 and resistance R1 parallel connection are in circuit.
When having material through vibroswitch S1, produce pulse signal, under the effect of electric capacity C1, pulse signal is converted to the DC switch signal that fluctuation is less, because the input impedance of sense switch signal is likely very large, electric capacity C1 is indefinite for discharge time, switching signal will produce indefinite long delay, therefore, after electric capacity C1, a resistance R1 in parallel, postpones with erasure signal.Resistance R1 value is particularly important, and resistance is too large, and time of delay is oversize, and resistance is too little, and electric capacity C1 cannot play the effect of rectification.It is 1 second that the utility model arranges resistance R1 by the tele-release complete time more than in electric capacity C1, disappears that to tremble duration be 1 second namely in setting.If vibroswitch S1 friction after 1 second, then think do not have material in pipeline.
