AI Technical Summary
In the existing technology, fixed single-axis detection devices cannot simultaneously detect material frames in both horizontal and vertical directions, and they also suffer from problems such as easy sensor damage, high cost, and difficult maintenance.
A dual-axis pneumatic protection and detection device was designed, which adopts a pneumatic flipping mechanism and a magnetic induction sensor. The horizontal and vertical material frame detection is achieved through a pneumatic control valve and a spring assembly. The sensor is flipped under the drive of the pneumatic flipping mechanism, the spring buffers the impact of the material frame, and the pneumatic control valve is protected by a rubber cover.
This invention enables a single sensor to simultaneously detect material frames in two directions, extending the service life of the sensor and pneumatic control valve, reducing costs, simplifying the structure, adapting to harsh environments, facilitating maintenance, and ensuring quiet and energy-efficient operation.
