[0054] In some embodiments, the heat flow conveying device 2 includes at least two fixed frames 201, a hot air blower 202, at least two exhaust ducts 203, a purification filter 204, and a negative pressure fan 205. The fixed frames 201 are connected to the base 1; the hot air blower 202 is connected to the fixed frames 201; one end of the exhaust duct 203 is connected to the material cylinder device 3, and the other end of the exhaust duct 203 passes through the fixed frames 201 and is connected to the hot air blower 202; the purification filter 204 is connected to the end of the exhaust duct 203 away from the fixed frames 201; one end of the negative pressure fan 205 is connected to the material cylinder device 3, and the other end of the negative pressure fan 205 is connected to the fixed frames 201.

[0056] In some embodiments, the feed cylinder device 3 includes a drying cylinder 301, a first driving member 302, a telescopic cover plate 303, and a control cylinder 304. One side of the drying cylinder 301 is connected to the side of the exhaust duct 203 away from the fixed frame 201, and the other side of the drying cylinder 301 is connected to the side of the negative pressure fan 205 away from the fixed frame 201. A groove (not shown in the figure) is provided on the top side of the drying cylinder 301. The first driving member 302 is connected to the top side of the drying cylinder 301. The first driving member 302 is an electric telescopic rod. One side of the telescopic cover plate 303 is connected to the inside of the top side of the drying cylinder 301, and the other side of the telescopic cover plate 303 passes through the drying cylinder 301 and is connected to the first driving member 302. The telescopic cover plate 303 can cover the groove. The control cylinder 304 is connected to the end of the first driving member 302 away from the hot air blower 202. An electromagnetic valve is provided at the bottom of the control cylinder 304.

[0057] A groove is provided on the top side of the wire drying cylinder 301. When the telescopic cover plate 303 is in the... Fig. 1 When in the indicated position, the telescopic cover 303 can completely cover the trough. When the first driving component 302 retracts, it simultaneously drives the telescopic cover 303 to retract. The tobacco material is stored inside the control cylinder 304, and an electromagnetic valve is provided at the bottom of the control cylinder 304. While the telescopic cover 303 retracts, the control cylinder 304 moves horizontally in sync. The electromagnetic valve opens and closes at regular intervals, which can guide the tobacco material inside the control cylinder 304 through the trough and quantitatively and evenly drop it onto the material tray device 5.

[0058] It should be noted that the first driving component 302 is not limited to an electric telescopic rod. It can also be a linear motor, electric cylinder, or pneumatic cylinder, as long as it can achieve synchronous movement and adjustment of the material control cylinder 304 and the telescopic cover plate 303. No specific limitation is made here.

[0059] In some embodiments, the feeding tray device 5 includes a second driving member 501, a feeding tray 502, at least two mesh frame partitions 503, a groove 504, at least two transmission frames 505, a scraper 506, and a third driving member 507. The second driving member 501 is connected to the inside of the drying cylinder 301; the second driving member 501 is an electric shaft seat; the feeding tray 502 is connected to the second driving member 501; the mesh frame partitions 503 are connected to the top side of the feeding tray 502; the groove 504 is disposed on the top side of the feeding tray 502, and the groove 504 is disposed in the middle of the two mesh frame partitions 503; the transmission frame 505 is connected to the feeding tray 502; the scraper 506 is slidably connected to the inside of the groove 504; the third driving member 507 is connected to the feeding tray 502, and the third driving member 507 passes through the groove 504 and is connected to the scraper 506; the third driving member 507 is an electric telescopic rod.

[0060] When the tobacco shreds are quantitatively and evenly guided into the groove 504, the hot air blower 202 and the negative pressure blower 205 operate synchronously to guide the hot gas horizontally in a directional manner, thereby achieving continuous drying of the tobacco shreds in the groove 504. After the drying is completed, the hot air blower 202 and the negative pressure blower 205 stop operating synchronously. Driven by the second drive unit 501, the material tray 502 is rotated axially by 90 degrees. Under the action of gravity, the tobacco shreds in the groove 504 are guided onto the material conveying device 6. After the material tray 502 rotates axially by 90 degrees, the third drive unit 507 drives the scraper 506 to move along the inside of the groove 504 towards the side closer to the transmission frame 505, pushing the tobacco shreds adhering to the bottom side of the groove 504 onto the material conveying device 6.

[0061] It should be noted that the second drive component 501 is not limited to an electric shaft seat; it can also be a linear motor, electric cylinder, or pneumatic cylinder, as long as it can achieve the rotational adjustment of the material tray 502. No specific limitation is made here. Similarly, the third drive component 507 is not limited to an electric telescopic rod; it can also be a linear motor, electric cylinder, or pneumatic cylinder, as long as it can achieve the movement adjustment of the scraper 506. No specific limitation is made here.

[0062] In some embodiments, the material conveying device 6 includes at least two elastic elements 604, a blocking plate 601, a fourth driving element 602, and at least two arc-shaped frames 603. The elastic elements 604 are connected to the drying cylinder 301; the blocking plate 601 is movably connected to the drying cylinder 301 and is connected to the elastic elements 604. A slot (not shown in the figure) is provided on the bottom side of the drying cylinder 301, and the blocking plate 601 can close the slot; the fourth driving element 602 is connected to the blocking plate 601; the fourth driving element 602 is an electrically driven rotating plate frame; the arc-shaped frames 603 are connected to the side of the blocking plate 601 away from the elastic elements 604. An elastic force sensor (not shown in the figure) is provided inside the elastic element 604, and the elastic force sensor is electrically connected to a PLC logic processor (not shown in the figure). The PLC logic processor is electrically connected to the fourth driving element 602.

[0063] A slot is provided on the bottom side of the wire drying cylinder 301, so that when the blocking plate 601 is in the case of... Fig. 1When the position shown is reached, the bottom slot of the drying cylinder 301 can be sealed and blocked. An elastic sensor is installed inside the elastic element 604. When the material tray 502 rotates 90 degrees, the synchronously rotating transmission frame 505 can continuously abut against the arc frame 603. In conjunction with the elastic element 604, the blocking plate 601 is moved down to the outside of the drying cylinder 301. When the elastic force value of the elastic sensor inside the elastic element 604 reaches the set value, the PLC logic processor sends control information to control the fourth drive element 602 to rotate 90 degrees. Under the action of gravity, the tobacco material that falls onto the fourth drive element 602 is guided and transported in a secondary direction. A conveyor belt or transport trolley can be set between the base 1 and the drying cylinder 301 to realize the directional transfer of tobacco material.

[0064] The working principle of the tobacco drying machine provided by this utility model is as follows:

[0065] When the first driving component 302 retracts, it simultaneously drives the telescopic cover plate 303 to retract. The material control cylinder 304 stores tobacco shreds, and an electromagnetic valve is installed at the bottom of the cylinder. As the telescopic cover plate 303 retracts, the material control cylinder 304 moves horizontally. The electromagnetic valve opens and closes periodically, allowing the tobacco shreds inside the cylinder 304 to be quantitatively and evenly guided through the trough and onto the material placement tray device 5. When the tobacco shreds are quantitatively and evenly guided into the groove 504, the hot air blower 202 and the negative pressure blower 205 operate synchronously, directionally and horizontally guiding the hot gas to continuously dry the tobacco shreds in the groove 504. After drying, the hot air blower 202 and the negative pressure blower 205 stop operating synchronously. Driven by the second driving component 501, the material placement tray 502 rotates axially by 90 degrees. Under the action of gravity, the tobacco shreds in the groove 504 are guided onto the material transfer device 5. On the feeding device 6, when the feeding tray 502 rotates 90 degrees axially, the third driving component 507 drives the scraper 506 to move along the inside of the groove 504 towards the side closer to the transmission frame 505, pushing the tobacco shreds adhering to the bottom side of the groove 504 onto the material conveying device 6. When the feeding tray 502 rotates 90 degrees, the synchronously rotating transmission frame 505 can continuously abut against the arc frame 603, and in conjunction with the elastic component 604, drive the blocking plate 601 to move down to the outside of the drying cylinder 301. When the elastic force value of the elastic sensor inside the elastic component 604 reaches the set value, the PLC logic processor sends control information to control the fourth driving component 602 to rotate 90 degrees. Under the action of gravity, the tobacco shreds that fall onto the fourth driving component 602 are conveyed in a secondary directional manner. A conveyor belt or transport trolley can be set between the base 1 and the drying cylinder 301 to realize the directional transfer of tobacco shreds.

[0066] The tobacco drying machine provided by this utility model can realize batch feeding of tobacco shreds, timely dissipation of hot and humid gas during drying, and ensure the moisture content of tobacco shreds. At the same time, the material tray device 5, together with the material conveying device 6, can effectively remove residual tobacco shreds during the conveying of tobacco shreds, and can also realize two-stage directional conveying of tobacco shreds, further improving the overall operating efficiency of tobacco processing and preventing waste of tobacco shreds.
