[0018] As Figures 1 to 3 shown, for an automatic discharging structure for abnormal materials of a metal detector, a diversion chute 3 is provided at the discharging port position of the metal detector 1. The middle part of the diversion chute 3 is hinged to the support seat 6 through a rotating shaft 8. One end of the rotating shaft 8 in the middle part of the diversion chute 3 is connected to the output end of the servo motor 5. The servo motor 5 is electrically connected to the controller 2 of the metal detector 1. An abnormal material bin 4 is provided between the support seat 6 and the conveyor belt of the metal detector 1;
[0019] When the controller 2 controls to detect metal inside the material, the controller 2 controls the servo motor 5 to drive the diversion chute 3 to turn in direction to convey the material containing metal into the abnormal material bin 4.
[0020] A diversion chute 3 is provided at the discharging port position of the metal detector 1. The function of the diversion chute 3 is to divert the materials after detection. The middle part of the diversion chute 3 is hinged to the support seat 6 through a rotating shaft 8, and the diversion chute 3 can turn around the rotating shaft 8. The servo motor 5 provides power for the turning of the diversion chute 3. When the controller 2 detects that there is metal inside the material, it will send out a control signal.
[0021] The abnormal material bin 4 is used to receive the abnormal materials detected to contain metal.
[0022] On the food production line, normal materials will continue to be conveyed in one direction along the material distribution chute 3. Once metal is detected, the controller 2 will command the servo motor 5 to drive the material distribution chute 3 to flip, so that the materials containing metal change the flow direction and fall into the abnormal material bin 4, realizing the function of automatically separating abnormal materials and improving production efficiency and product quality.
[0023] In a preferred embodiment, at least two fixed seats 301 are provided on the lower surface of the material distribution chute 3. Both ends of the rotating shaft 8 are fixedly connected to the fixed seats 301. A plurality of hinge seats 9 are provided on the support seat 6, and the hinge seats 9 are rotatably connected to the rotating shaft 8. The plurality of hinge seats 9 provided on the support seat 6 are rotatably connected to the rotating shaft 8. When the rotating shaft 8 is driven by the servo motor 5, it can rotate smoothly and stably under the support and guidance of the hinge seats 9, thereby driving the material distribution chute 3 to complete accurate flipping and material distribution operations.
[0024] In a preferred embodiment, the output end of the servo motor 5 is connected to the rotating shaft 8 through a transmission belt 7. The transmission belt 7 can effectively transmit the power generated by the servo motor 5, transfer the rotational motion from the output end of the servo motor 5 to the rotating shaft 8, and thus drive the material distribution chute 3 to perform a flipping action.
[0025] In a preferred embodiment, the servo motor 5 is connected to the transmission belt 7 through a reduction gearbox. The reduction gearbox can reduce the output speed of the servo motor and increase the output torque. This makes the force transmitted to the transmission belt 7 and the rotating shaft 8 stronger and more stable, which helps to more accurately control the flipping action of the material distribution chute 3. Through the adjustment of the reduction gearbox, the flipping speed of the material distribution chute can be made more appropriate, avoiding the spilling of materials or inaccurate material distribution caused by too fast or too slow flipping.
[0026] In a preferred embodiment, the width of the material distribution chute 3 is wider than the width of the conveyor belt of the metal detector 1. It can ensure that all the materials conveyed from the conveyor belt fall into the material distribution chute 3, avoiding the spilling of materials due to the insufficient width of the material distribution chute 3 and ensuring the integrity and continuity of material transmission.
[0027] In a preferred embodiment, an inverted arc 302 is provided on the baffle on the side of the end of the abnormal material discharge port of the material distribution chute 3. The direction of the inverted arc 302 is the abnormal material discharge port.
[0028] The above embodiments are only the preferred technical solutions of the present invention and should not be regarded as limitations on the present invention. The protection scope of the present invention should be the technical solutions recorded in the claims, including the equivalent replacement solutions of the technical features in the technical solutions recorded in the claims. That is, the equivalent replacement improvements within this scope are also within the protection scope of the present invention.
