The rotating plate 308 is located at the middle position of the placement plate 306, which is convenient for subsequent classification work. The spring 310 can restore the rotating plate 308 to its original position, and the end of the connecting plate 309 away from the placement plate 306 and the rotating plate 308 are not in the same vertical plane.

[0039] Embodiment 2

[0040] As Figures 2-5 shown, a metal foreign object detection device proposed by the present utility model, compared with Embodiment 1, the structure introduced in detail in this embodiment.

[0041] The detection and classification mechanism includes a detection component, a classification component, a collection box 408, and a pull ring 409; the collection box 408 is slidably arranged inside the workbench 1, and the pull ring 409 is arranged outside the collection box 408; the detection mechanism is arranged on the top of the workbench 1 for detecting the metal foreign matter content of the wet wipes at the bottom, and controlling the start of the classification component through the computer 402; the classification component is arranged on the top of the workbench 1 and directly above the collection box 408 for removing the wet wipes with excessive metal content. The detection mechanism includes a fixed table 401, a computer 402, and a detector 403; the fixed table 401 is arranged on the top of the workbench 1, the computer 402 is arranged on the side of the fixed table 401, the detector 403 is arranged at the bottom of the fixed table 401, and the detector 403 is directly above the middle position of the conveying mechanism. The detector 403 detects the metal content of the wet wipes. When the metal content exceeds the standard, the detector 403 will feedback to the computer 402, and the computer 402 will control the start of the classification component and the shutdown of the motor 301, so that the conveyor belt 304 stops running, and the unqualified wet wipes with excessive metal content are removed. The classification component includes a cylinder 404, a connecting frame 405, a push rod 406, and a pushing block 407; the connecting frame 405 is arranged on the top of the workbench 1, the cylinder 404 is arranged on the top of the connecting frame 405, the push rod 406 is arranged at the output end of the cylinder 404, the pushing block 407 is arranged at the bottom of the push rod 406, and the thickness of the pushing block 407 is slightly less than the width of the rotating plate 308, which is convenient for smoothly pressing the wet wipes on the placing plate 306 through the rotation and opening of the rotating plate 308 and pressing them into the collection box 408 when pressing downwards.

[0042] In summary, when the present utility model is in use, the motor 301 is started. The motor 301 drives the roller 305 to rotate through the rotating shaft 303, and the roller 305 drives the conveyor belt 304 to move. The wet wipes are placed on the conveyor belt 304. During the movement of the conveyor belt 304, the wet wipes will contact the guiding platform 307. Since the guiding platform 307 contacts but is not connected to the conveying component and is set in a shape with the opening gradually narrowing from the outside to the inside, it is convenient to squeeze the wet wipes placed on the conveying component onto the placing plate 306. The wet wipes on the placing plate 306 move along with the conveyor belt 304. When the conveyor belt 304 moves to the bottom of the detector 403, the detector 403 detects the wet wipes. When it is detected that the metal content inside the wet wipes exceeds the standard, the detection result is feedback to the computer 402. The computer 402 controls the motor 301 to stop rotating, thereby driving the conveyor belt 304 to stop moving. At the same time, the computer 402 controls the cylinder 404 to start. The cylinder 404 drives the push rod 406 to move downwards, and the push rod 406 drives the pushing block 407 to move downwards, so as to press out the unqualified wet wipes from the conveyor belt 304 and drop them into the collection box 408. The collection box 408 can be pulled out through the pull ring 409 to take out the wet wipes in the collection box 408. The qualified wet wipes will not start the cylinder 404 and will enter the next processing stage along the conveyor belt 304.
