[0002] Currently, in the tobacco industry, according to tobacco leaf shredding production process requirements, tobacco leaves in the shredder must not be mixed with metal debris. The shredder's front feed trough is equipped with a metal detector. If metal debris is found in the incoming tobacco leaves, the feed trough's flap valve opens, and the tobacco leaves mixed with metal debris fall out and are removed, preventing metal debris from entering the shredder and causing malfunctions such as blade failure.

[0003] However, the discarded tobacco leaves need to be manually picked and then mixed into the current batch for shredding processing. Manual picking is inefficient and the picking effect is poor, resulting in waste of tobacco leaves. Utility Model Content

[0016] Beneficial effects of the utility model:

[0017] The utility model provides a tobacco leaf metal debris picking device. When a metal detector detects metal debris in incoming tobacco leaves, a flap valve opens, and the tobacco leaves are removed.

Among them, the upper end of the blanking channel 100 corresponds to the flap valve of the shredder feeding vibration trough 10, the shredder feeding vibration trough 10 is provided with a metal detector 20 aligned with the flap valve, and the lower end of the blanking channel 100 is provided with a blanking port 110; the upper end of the baffle plate 200 is connected to the inner wall of the blanking channel 100; the material discharging roller 300 is arranged on the inner wall of the blanking channel 100, and the material discharging roller 300 is located below the material discharging plate 200, the lower end of the material discharging plate 200 faces the material discharging roller 300, and the lower end of the material discharging plate 200 is spaced apart from the inner wall of the blanking channel 100; the upper end of the electromagnet suction plate 400 is rotatably connected to the inner wall of the blanking channel 100, and the electromagnet suction plate 400 is located below the material discharging roller 300.

[0029] The tobacco leaf metal debris picking device provided by the utility model is characterized in that when the metal detector 20 detects metal debris in the incoming tobacco leaves, the flap valve opens, the tobacco leaves are removed, and the removed tobacco leaves fall onto the baffle plate 200 in the material drop channel 100 below. Then, under the action of gravity, the tobacco leaves slide from the baffle plate 200 to the material roller 300. The material roller 300 rotates to drop the tobacco leaves onto the electromagnet suction plate 400. The metal debris is adsorbed by the electromagnet suction plate 400, and then, under the action of gravity, the tobacco leaves fall from the electromagnet suction plate 400 into the material drop port 110. Through the baffle plate 200 and the material roller 300, the tobacco leaves fall evenly onto the electromagnet suction plate 400. The electromagnet suction plate 400 can effectively adsorb metal debris in the tobacco leaves. Compared with manual picking, the picking efficiency is guaranteed, the picking effect is better, and the waste of tobacco leaves is reduced.

[0030] In some embodiments, a metal removal channel 500 is provided on the outer wall of the blanking channel 100 near the electromagnet suction plate 400. The metal removal channel 500 communicates with the blanking channel 100, and the electromagnet suction plate 400 can rotate into the metal removal channel 500. The above structure allows the electromagnet suction plate 400 to rotate into the metal removal channel 500. When the electromagnet suction plate 400 rotates into the metal removal channel 500, the electromagnet suction plate 400 is powered off. After the power is turned off, the electromagnet suction plate 400 loses its magnetism, allowing metal debris to break away from the electromagnet suction plate 400, and the metal removal channel 500 can smoothly discharge the metal debris.

[0031] In some embodiments, a feed port 120 is provided at the upper end of the discharge channel 100. The feed port 120 corresponds to the flap valve of the shredder feed trough 10. The opening of the feed port 120 gradually increases from the lower end to the upper end. This structure makes the feed port 120 approximately funnel-shaped, which further facilitates the entry of tobacco leaves into the discharge channel 100.

[0032] In some embodiments, a drive motor is provided on the inner wall of the blanking channel 100, and the feed roller 300 is connected to the rotating end of the drive motor. Specifically, the metal detector 20 is electrically connected to a controller, and the controller is electrically connected to the drive motor. When the metal detector 20 detects metal debris in the incoming tobacco leaves, the flap valve opens, and the tobacco leaves slide onto the baffle plate 200 in the blanking channel 100 below. Then, under the action of gravity, the tobacco leaves slide from the baffle plate 200 to the feed roller 300. The metal detector 20 transmits a signal to the controller, which controls the operation of the drive motor, and the rotating end of the drive motor drives the feed roller 300 to rotate.

[0033] In order to ensure the effect of the material-moving roller 300 on the tobacco leaves, in some embodiments, the material-moving roller 300 is provided with a plurality of material-moving teeth 310 along the circumference. Specifically, the plurality of material-moving teeth 310 are evenly distributed along the circumference of the material-moving roller 300.
