[0002] Cut tobacco is a crucial step in cigarette production. Its primary goal is to ensure consistent quality of the tobacco used for rolling, ensuring a uniform raw material ratio, appropriate tobacco width, and uniform moisture content. Furthermore, the tobacco must have a high filler value and meet required toughness. During cigarette product development, maintenance, and formulation adjustments, single-material tobacco testing is often used in the laboratory to analyze the characteristics of different tobacco leaf varieties. However, most tobacco leaf tobacco has uneven moisture content, and direct cutting results in broken tobacco. Excessively short tobacco leaf can also affect the quality of the rolled cigarette. Therefore, it is necessary to allow the tobacco leaf to recrystallize before cutting.

[0003] The existing tobacco strip water replenishment and regulation equipment includes a box body and a humidification component built into the box body. The humidification component includes a first bin body and an atomizing nozzle and a rotating part built into the first bin body. A stirring rack is provided on the rotating part to facilitate uniform water replenishment and moisture restoration of the tobacco strips. However, the stirring rack will damage the tobacco strips while stirring them, and the width of the subsequent shredded tobacco strips cannot be guaranteed, which greatly reduces the shredded tobacco quality and thus affects the quality of cigarette rolling.

[0004] Based on this, a tobacco processing equipment is urgently needed to solve the above-mentioned problems. Utility Model Content

[0005] Based on the above, the purpose of the present invention is to provide a tobacco processing device without a stirring rack, thereby preventing damage to the tobacco leaves, improving the uniformity of the moisture content of the tobacco leaves, and improving the quality of subsequent shredded tobacco.

[0032] like Figure 1 As shown, this embodiment provides a tobacco processing device, which includes a material bin 1 and a rehumidification device 2. Specifically, the rehumidification device 2 is arranged in the material bin 1, and the rehumidification device 2 includes a drum 21, a drive component 22, a spray component 23 and a blowing component 24. The drive component 22 is installed on the top of the material bin 1 and is driven and connected to the drum 21. The drive component 22 is used to drive the drum 21 to rotate. The spray component 23 and the blowing component 24 are arranged in the drum 21. The spray component 23 is used to spray water mist into the drum 21, and the blowing component 24 is used to blow air into the drum 21. A first feed port is provided on the top of the material bin 1, and a second feed port corresponding to the first feed port is provided on the top of the drum 21. The tobacco sheets can enter the drum 21 through the first feed port and the second feed port.

[0033] When the tobacco strips need to be humidified, they enter drum 21 through the first and second feed ports. Drive assembly 22 then rotates drum 21. As drum 21 rotates the tobacco strips, spray assembly 23 sprays water mist into drum 21, and blower assembly 24 blows air into drum 21. The combination of the water mist, air blows, and the rotation of drum 21 creates a spiral airflow within bin 1, ensuring uniform and rapid rehumidification of the tobacco strips. Compared to the prior art, this embodiment does not include a stirring rack, preventing damage to the tobacco strips. This improves the uniformity of moisture content in the tobacco strips and enhances the quality of subsequent shredded tobacco.

[0034] The tobacco processing equipment further includes a shredder 3. A discharge port 211 is provided at the bottom of the drum 21. The shredder 3 is disposed within the material bin 1 and below the discharge port 211. The discharge port 211 is provided with a first valve. The shredder 3 is used to cut the tobacco into sheets. When the rehumidification device 2 humidifies the tobacco sheets to a certain humidity, the drive assembly 22 stops driving, the first valve opens, and the humidified tobacco sheets move through the discharge port 211 to the shredder 3, where they are cut into shreds.

[0035] Preferably, the discharge port 211 is in the shape of a funnel that is wide at the top and narrow at the bottom, so that the tobacco sheets can be accurately moved to the shredding device 3 through the discharge port 211 .

[0036] Preferably, the inner wall of the drum 21 is provided with a moisture meter 25 for detecting the humidity of the tobacco sheets within the drum 21. The moisture meter 25 enables accurate, real-time measurement of the humidity of the tobacco sheets. In use, the moisture meter 25 measures the moisture content of the tobacco sheets before rehumidification and determines the amount of water required for rehumidification. The spray assembly 23 adjusts the water spray rate based on the required amount, automatically spraying water onto the unrehumidified tobacco sheets. When the moisture meter 25 detects that the humidity of the tobacco sheets reaches a preset value, the drive assembly 22, spray assembly 23, and blower assembly 24 cease operation, the first valve opens, and the tobacco sheets are shredded. In this embodiment, the rehumidified tobacco sheets can be directly shredded after passing through the shredding device 3, thereby improving the efficiency of preparing tobacco samples.

[0037] Preferably, the second feed port is provided with a second valve. By controlling the opening and closing of the second valve, the amount of tobacco leaves fed into the drum 21 can be adjusted, and by controlling the opening and closing of the first valve, the amount of tobacco leaves discharged from the drum 21 can be adjusted. The first and second valves cooperate to prevent feed blockage and regulate the processing speed of the tobacco leaves.

[0038] Furthermore, in this embodiment, the drive assembly 22 includes a drive motor 221 and a drive shaft 222. The drive motor 221 is drivably connected to the drive shaft 222, and the drive shaft 222 is connected to the drum 21. Specifically, the drive shaft 222 can also be provided on a reducer 223. The drive motor 221 drives the drive shaft 222 of the reducer 223 to rotate, providing greater torque.

[0039] Preferably, a flange 212 is provided on the top of the drum 21, a connecting hole is provided at the center of the flange 212, and a flange portion 2221 is provided on the drive shaft 222. The drive shaft 222 partially extends into the connecting hole, and the flange portion 2221 is connected to the flange 212. The flange portion 2221 and the flange 212 can be detachably connected by screws, and the drive shaft 222 partially extends into the connecting hole, thereby improving the stability of the connection between the drive shaft 222 and the drum 21.

[0040] Further preferably, a bushing 26 is installed in the connecting hole, and the driving shaft 222 can extend into the bushing 26 to reduce the wear between the driving shaft 222 and the drum 21.

[0041] In this embodiment, the blowing assembly 24 includes a hot air blower and an air pump 241 with variable wind direction. The air pump 241 is arranged on the bottom wall of the drum 21, and the upstream of the air pump 241 is connected to the hot air blower. In this embodiment, the hot air blower can provide hot air with variable direction into the drum 21 through the air pump 241, and cooperate with the water mist in the drum 21 to form a spiral hot air flow in the drum 21, thereby improving the humidification efficiency of the tobacco leaves.

[0042] In this embodiment, the spray assembly 23 includes multiple atomizing nozzles and a water supply pipe. The multiple atomizing nozzles are arranged on the top of the drum 21. One end of the water supply pipe is connected to a water supply device, and the other end is connected to the multiple atomizing nozzles. The water supply device can spray water mist into the drum 21 through the water supply pipe and the atomizing nozzles to humidify the tobacco leaves. The water supply device can also be arranged on the drum 21 and rotate with the drum 21.

[0043] Furthermore, the shredding device 3 includes a first driving member 31 and a shredding roller 32. Both ends of the shredding roller 32 are rotatably connected to the inner wall of the material bin 1, and the first driving member 31 is fixed to the outer wall of the material bin 1, and the first driving member 31 is drivably connected to the shredding roller 32. Preferably, the shredding roller 32 can be rotatably connected to the outer wall of the material bin 1 via a bearing to improve the rotational stability of the shredding roller 32. The first driving member 31 can be a motor, which drives the shredding roller 32 to rotate to achieve shredding of the tobacco strips. This is a prior art and will not be described in detail here.

[0044] The shredding device 3 also includes a receiving tray 33, which is located below the shredding roller 32. After the tobacco sheets are shredded, the shredded tobacco falls into the tray, achieving automated tobacco preparation, which can then be used for the next experiment. The shredding device 3 of this embodiment can adjust the shredding width and shredding speed according to experimental requirements to meet different experimental needs.

[0045] Preferably, the slicing device 3 also includes a guide diversion component, which is arranged between the slicing roller 32 and the discharge port 211. The humidified tobacco leaves fall on the guide diversion component. The guide diversion component can evenly transport the tobacco leaves to the slicing roller 32, thereby improving the slicing efficiency and the uniformity of the slicing.

[0046] This embodiment also provides the working steps of the tobacco processing equipment, which are as follows:

[0047] The second valve on the second feed port is opened, and unrehumidified tobacco strips are placed into the material bin 1. After the feed is complete, the second valve on the feed port is closed, and the drive motor 221 is turned on. This drives the drum 21 to rotate, first measuring the tobacco strip moisture using a moisture meter 25 and adjusting the water spray volume from the spray assembly 23. As the tobacco strips within the drum 21 rotate along with the inner wall of the drum 21, the spray assembly 23 begins operating. Simultaneously, the hot air blower is turned on, spraying hot air into the drum 21, forming a spiral hot air flow within the drum 21. This uniformly and rapidly rehumidifies the tobacco strips until the desired humidity is reached. The drive assembly 22, spray assembly 23, and blower assembly 24 are then deactivated. The first valve is opened to control the tobacco strip flow rate and prevent clogging. The rehumidified tobacco strips pass through the funnel-shaped discharge port 211 and are uniformly fed into the shredder 3. The shredder 3 adjusts the shredding width and speed to meet the sample requirements of different experiments. The shredded tobacco strips automatically fall into the receiving tray 33 for the next step of the experiment.
