Problems solved by technology

This method of judgment still has defects in use, especially for the waste passages sealed inside the object, the photoelectric sensor cannot be installed, so it is impossible to use the detection means of photoelectric signals to monitor such special waste passages, thus making the prior art detection methods are severely limited

Embodiment 1

[0027] A waste clogging detection device for a waste channel 200 with unidirectional air flow comprising:

[0028] An air connection pipe 110, the air connection pipe 110 is used to communicate with the waste channel 200;

[0029] A joint cavity 120, the joint cavity 120 communicates with the air connection pipe 110, and a plectrum 130 is arranged in the joint cavity 120;

[0030] Proximity sensor 140, the proximity sensor 140 is connected with the paddle 130, when the air flow weakens or stops, the paddle 130 contacts with the proximity sensor 140 to generate an alarm signal.

[0031] Along the direction of the unidirectional air flow, an air end and an air intake end are divided, the air outlet end of the joint cavity 120 is in airtight communication with the air connection pipe 110 through the air pipe joint, and the air intake end of the joint cavity 120 When there is unidirectional air flow in the joint cavity 120 , the intake air will lift the paddle 130 away from the p...

Embodiment 2

[0039]A method for detecting waste blockage, using the waste blockage detection device of embodiment 1, comprising the steps of:

[0040] (1) The joint cavity is connected with the waste channel; the suction fan creates unidirectional air flow in the waste channel;

[0041] (2) When the waste channel is unblocked, in the direction of the air flow created by the suction fan, the paddle moves away from the proximity sensor with the air flow; when the air flow changes and the position of the paddle changes to trigger the proximity sensor, it is determined that the waste channel is blocked .

[0042] (3) The proximity sensor sends an output signal to the control module, and the control module outputs an alarm or shutdown command according to the output signal.

[0043] The waste blockage detection method can use the paddle to monitor the unidirectional air flow (i.e. the air flow in the waste channel) flowing in the air pipe. When the continuous air flow is maintained in the wast...

Abstract

The invention relates to a waste material blockage detection device and method which are used for a waste material channel with one-way air flow, and the device comprises an air connecting pipe whichis used for communicating with the waste material channel; a connector cavity which communicates with the air connecting pipe, wherein a shifting piece is arranged in the connector cavity; and a proximity sensor which is connected with the shifting piece, wherein when air flow is weakened or stopped, the shifting piece makes contact with the proximity sensor to generate an alarm signal. The devicecan monitor without directly contacting with waste materials, is low in false alarm rate, long in service life and convenient to maintain, and can be widely applied to a waste material channel sealedin a workpiece.

Description

technical field [0001] The invention relates to the technical field of waste material detection, in particular to a waste material blockage detection device and method. Background technique [0002] In the field of die processing technology, it is necessary to resolutely prevent waste from staying in the mold during work. Once waste is produced and stays in the channel, it will hinder the production process, not only affect work efficiency, but may also cause work errors, and it is easy to make molds. damage to parts, or even damage to the press. In order to meet the requirements of the production process, the prior art requires a detection process capable of judging whether there is a blockage. [0003] In the prior art, there is a detection method for waste clogging. A photoelectric sensor is used to monitor the permeability of the waste channel where the waste is generated. The waste passage is believed to be clogged. This method of judgment still has defects in use, e...
