Problems solved by technology

Its disadvantages: the photoelectric switch is used to detect the position of the abrasive belt, and the output signal is sent to the control mechanism to realize the function. Since the sander is a high-efficiency grinding method, a large amount of abrasive debris is generated, and the internal environment of the machine is very poor. The photoelectric switch requires a relatively high detection environment, so abnormal shutdowns due to lens pollution often occur, seriously affecting the normal use of the machine

Embodiment 1

[0011] Example 1: Refer to the attached Figure 1-3 . A device for detecting the position of the micro-air flow belt of a wide-band sander. The compressed air pipeline 7 communicates with the inlet end of the reversing valve 4 through a three-way connection, and communicates with the inlet end of the blowing pressure regulating valve 1. The outlet end of the pressure valve 1 is connected with the inlet end of the small air hole in the air control plate 2. The outlet of the air inlet end of the small air hole in the air control plate 2 blows out the air flow into the air inlet end of the air control plate 2 opposite to the small air hole Receiving the air flow, the air flow at the outlet end of the atmospheric hole communicates with the air inlet end of the air pressure amplifier 3 through the air path, and the air flow passes through the air pressure amplifier 3 to boost the ejector pin to realize the switching action of the reversing valve 4. The intake end of the head cylind...

Embodiment 2

[0012] Embodiment 2: On the basis of embodiment 1, a detection method for the position detection device of the micro airflow sanding belt of a wide band sander, the compressed air gas pipeline 7 enters 4-6kg / / cm 2 Compressed air, compressed air is divided into two ways by the three-way in the compressed air pipeline 7, one way directly enters the reversing valve 4, the other way to the blowing pressure regulating valve 1, the compressed air passes through the blowing pressure regulating valve 1 to enter the air Control board 2, the air flow blown from the air blowing hole 23 in the air control board 2 is blown into the opposite air connection hole 24 to receive the air flow. Since the air blowing hole 23 has a smaller diameter than the air connection hole 24, the micro air flow received by the air connection hole 24 passes through Air pressure amplifier 3, the air flow is amplified by the air pressure amplifier 3 to force the ejector pin in the air pressure amplifier 3 to push th...

Abstract

The invention relates to a device for detecting the position of a sanding belt of a wide belt sanding machine through micro air flow and a control method. According to the device, the micro air flow is adopted for detecting whether the sanding belt of the wide belt sanding machine deviates. A branch of a compressed air conveying pipeline is communicated with the air inlet end of a reversing valve through a tee joint, and a branch of the compressed air conveying pipeline is communicated with the air inlet end of an air blowing pressure-regulating valve. The air outlet end of the air blowing pressure-regulating valve is communicated with the air inlet end of a small air hole of an air control insertion plate, the outlet of the air inlet end of the small air hole of the air control insertion plate blows air flow, the air flow is blasted into the air control insertion plate, and a large air hole opposite to the small air hole receives the air flow. The air outlet end of the large air hole is communicated with the air inlet end of an air pressure amplifier through an air channel. The air flow is in switching cooperation with the control end of a reversing valve through a centre in the air pressure amplifier, and the two air outlet ends of the reversing valve are respectively communicated with the air inlet end of an oscillating cylinder. The device and control method have the advantage that the problem that due to the fact that a photoelectric detection head is polluted in the background technology, the disorderly closedown phenomenon of the sanding machine occurs frequently is solved fundamentally.

Description
