1. before the device is used, the transmission mechanism is not provided with a tobacco sheet box, and the first motor 102, the second motor 202 and the third motor 302 are all in a stop state. When the device is used, the tobacco-sheet box is placed on the first conveying belt 104 through a holding vehicle, after the tobacco-sheet box shields the first grating 105, the first grating 105 transmits signals to the controller, the controller controls the first motor 102 and the second motor 202 to rotate simultaneously, so that the first conveying belt 104 and the second conveying belt 204 are driven to move synchronously, the tobacco-sheet box on the first conveying belt 104 is transmitted to the second conveying belt 204, and in the process of transmitting the tobacco-sheet box to the second conveying belt 204, the tobacco-sheet box is arranged regularly and uniformly through the action of the limiting plates 6 in the first limiting assemblies 4 and the second limiting assemblies 5 at two sides, and through the telescopic action of the springs 402 in the first limiting assemblies 4, the extrusion action between the tobacco-sheet box and the limiting plates 6 is reduced, the buffer effect is achieved, and the extrusion action between the tobacco-sheet box and the limiting plates 6 can be further reduced through the arrangement of the guide wheels 7; the position of the sheet tobacco box in the transmission mechanism can be conveniently adjusted through the functions of the limiting cylinder 502 and the limiting rod 503 in the second limiting assembly 5.

2. Through step 1, the tobacco box on the second conveyor belt 204 will be gradually buffered, and the tobacco box on the second conveyor belt 204 will gradually move leftwards until the tobacco box shields the second grating 205, at this time, the second grating 205 transmits signals to the controller, and the controller controls the second motor 202 and the third motor 302 to rotate simultaneously, so as to drive the second conveyor belt 204 and the third conveyor belt 304 to rotate synchronously, and the tobacco box on the second conveyor belt 204 is transmitted to the third conveyor belt 304.

3. Through step 2, the third conveyor belt 304 gradually buffers the tobacco box, and the tobacco box on the third conveyor belt 304 gradually moves leftwards until the tobacco box shields the third grating 305, at this time, the third conveyor belt 304 buffers the tobacco box fully, the third grating 305 transmits signals to the controller, and the controller controls the second motor 202 and the third motor 302 to stop rotating, so as to avoid mutual collision of the tobacco boxes.

4. When the first grating 105 is shielded again, the first grating 105, the second grating 205 and the third grating 305 are shielded, the controller receives the signal, and covers the stop signal of the third grating 305, and starts the third conveyor 304 to transfer the goods on the third conveyor 304 to the bale opener 8. By providing the driven roller 9, the supporting force to the first conveyor belt 104, the second conveyor belt 204, and the third conveyor belt 304 can be improved, and the transfer of the present apparatus can be stabilized.

5.

6. At this time, as can be seen from step 3, the controller controls the second motor 202 to stop rotating when the third grating 305 is blocked, when the first grating 105 is blocked again, the signal that the controller controls the second motor 202 to rotate when the first grating 105 is blocked covers the signal that the controller controls the second motor 202 to stop rotating when the third grating 305 is blocked, so that the second conveyor belt 204 idles, and the empty space is rotated until the second grating 205 is blocked again, when the first grating 105 is blocked again, at this time, the first grating 105, the second grating 205 and the third grating 305 all have signals, i.e. the tobacco box can be transferred to the bale opener 8 as in step 4, so as to circulate.

In this cycle:

Signals for starting the first motor 102 and the second motor 202 after the first grating 105 is blocked are prioritized over signals for stopping the second motor 202 and the third motor 302 after the third grating 305 is blocked;

Signals to stop the second motor 202 and the third motor 302 after the third grating 305 is blocked are prioritized over signals to start the second motor 202 and the third motor 302 after the second grating 205 is blocked.

The device can improve the storage quantity of the tobacco boxes on the third conveyor belt 304 and reduce the existence of the vacant positions, thereby being capable of reducing the waiting time of the bale opener 8 and improving the working efficiency of the bale opener 8.
