[0036] The present application provides a tobacco cooling device, which cools the tobacco uniformly by air provided by air blowing devices on both sides of a receiving box while a material disturbing assembly disturbs the tobacco, and then cools the tobacco again by a water cooling assembly with an axis of symmetry, thereby greatly improving the cooling effect. Further, the water cooling cylinder has a double-layer structure, and the gap between the two layers forms an annular water storage cavity, which sprays water to the tobacco uniformly through the spray members, thereby accelerating the cooling speed of the tobacco compared with the single direction spraying, and thereby saving water resources on the basis of uniformly cooling the tobacco.

[0037] As shown in Figure 1 and 2 The present application provides a tobacco cooling device, which cools the tobacco uniformly by air provided by air blowing devices on both sides of a receiving box while a material disturbing assembly disturbs the tobacco, and then cools the tobacco again by a water cooling assembly with an axis of symmetry, thereby greatly improving the cooling effect. Further, the water cooling cylinder has a double-layer structure, and the gap between the two layers forms an annular water storage cavity, which sprays water to the tobacco uniformly through the spray members, thereby accelerating the cooling speed of the tobacco compared with the single direction spraying, and thereby saving water resources on the basis of uniformly cooling the tobacco.

[0038] The receiving box assembly 2 comprises a spherical receiving box 201, a disturbing assembly 6 arranged in the receiving box 201, and an air cooling assembly arranged on the receiving box 201.

[0039] The upper end of the receiving box 201 is provided with a cylindrical material guiding bin 202 extending upward along the vertical axis thereof as an entrance of tobacco shreds.

[0040] As an embodiment, the receiving box 201 is hoisted below the output port of a tobacco cutting machine by the hoisting frame 1, and the tobacco shreds cut by the tobacco cutting machine enter the material guiding bin 202 through the output port thereof.

[0041] The disturbing assembly 6 comprises a main shaft 602 extending downward from the lower end of the material guiding bin 202 along the vertical axis of the receiving box 201, a plurality of disturbing rods 603 symmetrically arranged on the main shaft 602, and a first driving member 601 arranged at the lower end of the main shaft 602. The first driving member 601 drives the main shaft 602 to rotate, and the disturbing rods 603 uniformly disperse the tobacco shreds into the inner cavity of the receiving box 201 when the main shaft 602 rotates.

[0042] As an embodiment, the first driving member 601 is an electric shaft seat.

[0043] Preferably, the upper end of the main shaft 602 is provided with a first material control assembly 7, and the guiding amount of the first material control assembly 7 in the first state is less than that in the second state.

[0044] As an embodiment, the first material control assembly comprises a guiding plate and a second driving member of the guiding plate. The second driving member is fixed to the upper end of the main shaft 602, the guiding plate is horizontally arranged, and a plurality of guiding holes are arranged on the guiding plate.

[0045] Specifically, as shown in Figure 1 and 4 , the upper end of the main shaft 602 is fixed with a horizontal fixing frame 701, two second driving members 702 are symmetrically arranged on the upper side of the fixing frame 701, thereby the second driving members 702 are fixed to the upper end of the main shaft 602. The output ends of the two second driving members 702 are symmetrically fixed to the lower side of a guiding plate 703, and a plurality of guiding holes 704 are arranged on the guiding plate 703.

[0046] As an embodiment, the second driving member 702 is an electric telescopic rod or a linear motor, or is driven by an electric cylinder or an air cylinder.

[0047] When the first driving member 601 drives the main shaft 602 to rotate, the guiding plate 703 rotates, and the tobacco shreds in the material guiding bin 202 can fall into the inner cavity of the receiving box 201 through the guiding holes 704, thereby further reducing the guiding speed of the tobacco shreds.

[0048] When the second driving member 702 is in the extended state, the guide plate 703 abuts against the inner wall of the receiving box 201, and the first material control assembly 7 is in the first state, at which time the tobacco can only enter the receiving box 201 from the guide hole 704.

[0049] When the tobacco in the guide bin 202 is too much, the second driving member 702 is started, the extension rod of the second driving member 702 is retracted, the guide plate 703 is lowered, and the guide plate 703 has a gap with the inner wall of the receiving box 201, and the first material control assembly 7 is in the second state, at which time the tobacco enters the receiving box 201 from the guide hole 704 and the gap, preventing the tobacco from being deformed and broken due to excessive accumulation. Therefore, compared with the first state, the second state has a larger amount of guided material.

[0050] The air cooling assembly includes two communication pipes 204 symmetrically arranged on the receiving box 201 and a blowing device (located outside the receiving box 201) connected with the communication pipes 204, and the communication pipes 204 penetrate the receiving box 201 from the outside to the inside. The blowing generated by the blowing device enters the receiving box 201 through the communication pipes 204 to air cool the tobacco.

[0051] Preferably, the inner wall of the receiving box 201 on which the communication pipe is arranged is provided with a purification filter bin 203, which separates the communication pipe from the inner cavity of the receiving box 201. The purification filter bin 203 filters and purifies the blowing gas to ensure the cleanliness of the gas entering the receiving box.

[0052] The water cooling assembly is arranged outside the lower end of the receiving box 201.

[0053] As an embodiment, as shown in Figure 1 and 3 , the water cooling assembly includes a double-layered, open-ended water cooling cylinder 301 and a plurality of spray members 302 uniformly arranged on the inner wall of the inner cylinder of the water cooling cylinder 301, and a valve 303 is arranged on the outer cylinder of the water cooling cylinder 301. The water cooling cylinder 301 has a tubular structure, and the tube wall has a double-layered structure. The gap between the two layers forms an annular water storage cavity. When the valve 303 is opened, the cooling water enters the annular water storage cavity and is sprayed into the water cooling cylinder 301 through the spray members 302. The air-cooled tobacco falls from the discharge port of the receiving box 201 into the water cooling cylinder 301 and is further sprayed by the cooling water in the water cooling cylinder 301, further reducing the temperature of the tobacco. The water-cooled tobacco is output from the lower end of the water cooling cylinder 301, completing the entire cooling process of the tobacco.

[0054] As an embodiment, the spray member 302 is selected as an atomizing nozzle.

[0055] Preferably, the water cooling assembly further includes a second material control assembly 4 for controlling the amount of tobacco from the receiving box 201 to the water cooling cylinder 301.

[0056] Specifically, as shown in Figure 3 The bottom surface of the water-cooled cylinder 301 is fixed with a bottom bracket 304 along the axis. Figure 1 The second material control assembly 4 includes a third driving member 401 and a blocking bracket 402 fixed on the bottom surface of the first driving member 601. The blocking bracket 402 is in the shape of a truncated cone with a small top and a large bottom. The main body of the third driving member 401 is fixed on the bottom bracket 304, and the output end of the third driving member 401 is fixedly connected with the blocking bracket 402.

[0057] As an embodiment, the third driving member 401 is selected as an electric telescopic stand or a linear motor, or is driven by an electric cylinder or a pneumatic cylinder.

[0058] Under the driving action of the third driving member 401, the blocking bracket 402 moves up and down, thereby enlarging or reducing the gap between the blocking bracket 402 and the discharge port at the lower end of the receiving box 201, and thereby enlarging or reducing the discharge amount of the receiving box 201.
