At the same time, the anvil assembly fits the front conveyor and the rear conveyor as closely as possible to avoid leakage. In addition, there is a height difference between the front and rear anvils of the anvil assembly, that is, the front first anvil is higher than the second anvil, so that the tobacco leaves can fall and separate better after being cut by the cutter.

[0090] 12. The leaf pressing equipment of the present invention can apply uniform pressure to the material, effectively preventing the material from sliding, tilting or piling up during the transportation process, ensuring that the material remains stable, reducing production interruptions due to displacement or instability, thereby improving the stability of material transportation, reducing material damage, improving transportation efficiency, and enhancing the safety and flexibility of the system.

[0182] In summary, a more specific embodiment of the present invention is:

[0183] Before using the tobacco leaf bidirectional cutting device with the above-mentioned design structure, it is necessary to manufacture and install it as a backup.

[0184] The specific steps are:

[0185] Before use, the operator first controls the two pressing drivers 52 through the control device to adjust the distance between the pressing conveyor 51 and the conveying belt of the front conveyor 11 to meet the pressing requirements;

[0186] The operator pushes the two vertical sliding plates 43 to drive the leaf pressing device 49 connected thereto, and adjusts the distance between the two cutting devices 47 on the cross-cutting connecting frame 41 and the cutting height of each cutting device 47 to meet the transverse cutting requirement of the material 6; at the same time, the cross-cutting driver 46 is controlled by the control device to adjust the height of the cutting device 47 connected thereto, and then, a pre-prepared locking bolt is passed through the vertical sliding plate 43 and the fixed block 431 and connected to the outer side of the cross bar sliding groove through a locking nut. At the same time, after the adjustment is completed, the spacing adjustment of the two cutting devices 47 is completed by fixing them with the locking nut. After adjusting to the appropriate position and fixing them firmly and reliably, they can be used.

[0187] When in use, the control device first starts the conveying component 1, the longitudinal cutting component 3 and the transverse cutting component 4 to start working; when the upstream device conveys the material 6 to the top of the front conveyor 11, the material 6 gradually enters the bottom of the pressing component 5 along the conveying belt of the front conveyor 11;

[0188] Then, the driving member 31 drives the transmission member 33 to rotate through the longitudinal cutting transmission chain 39, and then the transmission member 33 drives the rocking arm 341 connected thereto to rotate, so that the rocking arm 341 drives the connecting rod 342 to move, and the connecting rod 342 drives the longitudinal cutting slider 36 to move linearly along the longitudinal cutting sliding guide rail 35, and the longitudinal cutting slider 36 drives the cutter seat 37 connected thereto to drive the cutter 38 to move up and down, and finally the material 6 is cut;

[0189] Then, the material 6 is driven by the rear conveyor 12 and the pressure chain 495 to reach the bottom of the two cutting devices 47, and the two cutting devices 47 cut the material 6 below respectively;

[0190] Finally, after the material 6 is cut, it enters the downstream equipment driven by the rear conveyor 12 and the pressure leaf chain 495, thus completing the longitudinal and transverse cutting of the material.

[0191] During the above-mentioned use, the limiting gear assembly 3a can ensure the stability of the transmission of the longitudinal cutting transmission chain 39; the pressing piece 3b moves up and down with the cutter seat 37, which can make the material 6 after passing through the pressing assembly 5 to be better compacted, and facilitate the cutting work of the cutter 38. At the same time, a buffer device is provided on the pressing piece 3b, which can better protect the material 6 and prevent the material 6 from being crushed.
