DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the utility model will be described clearly and completely in combination with the drawings in the embodiments of the utility model.

[0021] Embodiments of the utility model:

[0022] For example, Figures 1-3As shown, a food metal detector comprises two first conveying belts 1 arranged at intervals and a second conveying belt 2 located between the two first conveying belts 1, the conveying direction of the second conveying belt 2 is opposite to that of the first conveying belt 1; a metal detector body 3 is located above the first conveying belt 1 and the second conveying belt 2; one end of each of the two first conveying belts 1 is provided with a guide plate 10 for guiding food to the second conveying belt 2; a baffle 15 is arranged between each of the two first conveying belts 1 and the second conveying belt 2.

[0023] When the food is conveyed, it is first conveyed by the first conveying belt 1, and at this time, it passes the metal detector body 3 for the first time; when the food reaches the guide plate 10 through the first conveying belt 1, the food collides with the guide plate 10, and under the action of the guide plate 10, the food enters the first conveying belt 1; during the whole process, the angle of the food changes immediately, and then the food passes the metal detector body 3 again on the second conveying belt 2 for re-inspection, so as to effectively avoid the detection error caused by the angle of the food and further improve the detection effect of the metal detector.

[0024] It should be noted that a pushing mechanism can be arranged between the guide plate 10 and the metal detector body 3, so as to remove the food containing metal detected on the first conveying belt 1; the specific removal structure can be located above the first conveying belt 1; since this technology is common in the industry, it is prior art, and therefore the structure and principle thereof will not be described herein.

[0025] In some further embodiments, the guide plate 10 is rotatably provided with a pushing rod 14, and the top of the pushing rod 14 is drivingly connected with a first motor 16.
