Description
Technical Field
The utility model relates to a dust keeper of disconnected paper detection sensor belongs to the equipment of papermaking trade.
Background
On the papermaking production line, install the sensor that is used for the paper breakage to detect, when the paper normally removes, can not report to the police, when the paper breakage, the sensor can export alarm signal to the controller, the production line can stop production, maintain, the sensor adopts infrared emission receiver tube usually, during normal production, infrared emission's signal can be received by infrared receiver tube after the paper reflection, if the paper breakage, the unable received signal of infrared receiver tube, begin to report to the police, in the prior art, infrared emission receiver tube can be blockked by the dust that the paper produced, thereby cause the warning malfunctioning.
SUMMERY OF THE UTILITY MODEL
The utility model discloses it is not enough according to above, provide a dust keeper of disconnected paper detection sensor.
The technical scheme of the utility model is that:
a dust-proof device of a paper break detection sensor, comprising:
the sensor transmitting tube and the sensor receiving tube are fixed on the frame, the sensor transmitting tube and the sensor receiving tube are aligned with paper moving on a papermaking production line to transmit and receive photoelectric signals, the sensor is electrically connected with a controller of the papermaking production line, and when the paper is broken, the sensor receiving tube outputs a paper breaking signal to the controller;
it is characterized by also comprising:
the dust cover is fixed on the frame, the sensor transmitting tube and the sensor receiving tube are installed in the dust cover, an air inlet is formed in the top of the dust cover and communicated with the air pump through a pipeline, and positive pressure is formed in the dust cover.
Through setting up the dust cover and just pressing the air current, can ensure that the dust on the paper can't shelter from sensor transmitting tube, sensor receiver tube to can guarantee that alarming function can not become invalid.
In order to save the gas and make the air current even simultaneously, install the perforated plate in the dust cover, this perforated plate is fixed in the top of sensor launching tube and sensor receiving tube, and the perforated plate enables the even downward flow of air current in the dust cover.
Preferably, the sensor transmitting tube and the sensor receiving tube are infrared pair tubes.
To ensure that the intake air is clean, the intake is provided with a dust filter.
Preferably, the dust cover has a cylindrical shape.
The utility model has the advantages of simple structure, low cost, convenient installation and use and obvious dustproof effect.
