before working, the material plate is in the original position under the action of the spring force of the vortex spring, and the cylinder rod is also in the original position.
When the tobacco leaf material 9 containing metal foreign matters is conveyed onto the conveying belt machine 7 by front-end equipment, the tobacco leaf material 9 continues to be conveyed forwards along with the conveying belt 71, when the tobacco leaf material 9 passes through the metal detector 72 above the conveying belt 71, the phase of a coil of the metal detector changes, the metal detector 72 recognizes that the metal foreign matters exist, meanwhile, a metal foreign matter signal is conveyed into the PLC, the PLC sends a corresponding control signal to the pneumatic electromagnetic valve, then the pneumatic electromagnetic valve is opened, high-pressure air enters the impact cylinder 31, at the moment, the tobacco leaf material 9 passes through the time T0 and just conveyed to the tail end of the conveying belt machine 7 to fall along with inertia, high-pressure air in the cylinder 31 pushes the cylinder rod 32 to move forwards, the cylinder rod 32 acts on the baffle plate 2 through the rod guide wheel 33, so that the baffle plate 2 rotates by about 50 degrees along the baffle plate shaft 1, the fallen tobacco leaf material 9 is just blocked by the baffle plate 2, then enters the feed inlet 51 of the blanking cylinder 5 along the baffle plate 2, the discharge outlet 52 of the cylinder 5 is positioned above the metal blanking belt machine 6, the foreign matters fall off the baffle plate 62 on the baffle plate 5, and the foreign matters fall on the baffle plate 5 through the baffle plate 62 and the baffle plate 5 at each time, and the time is just slipped down on the baffle plate 5 and the baffle plate 5 through the baffle plate 5. When the baffle plate 2 moves once to enable the tobacco leaf materials 9 to just fall into the separation units 62, the corresponding metal foreign matter separation belts 61 are driven by the motor to rotate after the time T2, so that the separation belts 61 are stopped after forwards conveying one separation unit 62, and when the baffle plate 2 moves again to enable the tobacco leaf materials 9 to fall into the separation units 62 on the separation belts 61, the separation belts 61 continue to forwards convey one separation unit 62. The material baffle 2 is turned over once, counted once, accumulated number is N1, when a certain number N0 (=n/3) is accumulated, warning is reminded on a computer operation picture of a corresponding process section, operators arrange corresponding personnel to turn over and pick up metal foreign matters, after all the metal foreign matters are turned over, a reset button on one side of the separation belt conveyor is pressed, the separation belt moves forward by N/2 units, and meanwhile N1 is cleared.
Finally, the tobacco leaf materials 9 after the metal foreign matters are picked up are guided by the guide plate 63 at the tail end of the metal foreign matter separation belt conveyor 6 and then conveyed to the conveying belt conveyor 7 again, then the tobacco leaf materials pass through the metal detector 72 again, after no metal foreign matters are detected, the guide plate is in situ, tobacco leaves on the conveying belt are thrown forward by inertia and fall onto the rear-end conveying belt conveyor 8, and then the next operation procedure is carried out.
In the whole implementation operation process, as the baffle plate 2 rotates through the baffle plate shaft 1, the two ends of the baffle plate shaft 1 are connected with the vortex springs 112 and 122, in the process of installing the vortex springs, the vortex springs are compressed, one sides of the left bracket 4 sleeve 11 and the right bracket 4 sleeve 12, which are close to the baffle plate 2, are respectively provided with the baffle plate left limiting block 131 and the baffle plate right limiting block 132, so that elastic potential energy of the vortex springs cannot be released, the baffle plate 2 rotates along the baffle plate shaft 1 after being acted by the air cylinder rod 32 at the moment of high-pressure air release, meanwhile, the vortex springs are further compressed, after the high-pressure air release is finished, the vortex springs are further compressed, the original state needs to be restored, and under the reaction of the vortex springs, the baffle plate 2 returns to the positions of the baffle plate left limiting block 131 and the right limiting block 132 along with the baffle plate shaft 1.
The foregoing has outlined rather broadly the more detailed description of the invention in order that the detailed description of the principles of the invention may be better understood. It should be noted that it will be apparent to those skilled in the art that the present invention may be modified and adapted without departing from the principles of the present invention, and such modifications and adaptations are intended to be within the scope of the appended claims.
