[0035] In the prior art, the tobacco leaves are usually crushed and ground into tobacco powder without adding water, then transported to a tank, and water, smoke-generating agent, fiber-containing liquid and other materials are added to mix to make a finished thick slurry, which is then entered into the subsequent process to make a finished thick slurry sheet. The process involves the preparation of tobacco powder. Since all tobacco leaves are ground into fine powder, not only more fiber needs to be added, which increases the cost, but also the fine tobacco powder has dust explosion safety hazards.

[0036] To solve the above problems, this embodiment provides a production line, including a thick slurry preparation system. Figure 1 The thick slurry preparation system includes a mixing mechanism 10, an abrasive mechanism 20 and a blending mechanism 30.

[0037] Further, the mixing mechanism 10 includes a mixing tank 11 and a water spraying member 12. The interior of the mixing tank 11 is hollow to carry tobacco leaves. The water spraying member 12 is arranged in the mixing tank 11 and communicated with the interior of the mixing tank 11. The water spraying member 12 is used to spray water on the tobacco leaves. The mixing tank 11 can rotate around a horizontal axis to stir the tobacco leaves and water to form a mixed slurry. In this embodiment, the mixing tank 11 is set to be cylindrical, and an opening is set at the top or end of the mixing tank 11. The opening is rotatably connected to a feeding funnel or a feeding pipe to facilitate the entry of tobacco leaves. In this embodiment, the water spraying member 12 is set to be a nozzle, and the nozzle is connected to a water pipe to realize a water spraying function. Specifically, a plurality of nozzles are arranged at intervals along the axial direction of the mixing tank 11. The plurality of nozzles can use one main water pipe or can be connected to a water pipe separately. In this embodiment, four water spraying members 12 are provided.

[0038] Furthermore, the mixing mechanism 10 also includes a rotating motor, which is connected to the mixing tank 11 to drive the mixing tank 11 to rotate around a horizontal axis. Specifically, a solenoid valve is provided on the nozzle. The solenoid valve, the rotating motor and the feeding funnel are connected in communication to ensure the proportion of the mixed slurry. Specifically, the weight of the water is 2.5 times the weight of the tobacco leaves.

[0039] Furthermore, the mixing mechanism 10 further includes a plurality of mixing teeth 13, which are arranged inside the mixing tank 11. In this embodiment, the mixing teeth 13 are arranged as plates. Specifically, a plurality of mixing teeth 13 are arranged at intervals along the axial direction of the mixing tank 11 to evenly mix the water and the tobacco leaves to ensure that the tobacco leaves are completely soaked.

[0040] Further, the abrasive mechanism 20 includes a first abrasive disc 21 and a second abrasive disc 22, and there is a gap between the first abrasive disc 21 and the second abrasive disc 22 to form an abrasive cavity, the abrasive cavity is connected to the mixing mechanism 10, the mixed slurry can enter the abrasive cavity, and the first abrasive disc 21 and the second abrasive disc 22 can rotate relative to each other to grind the mixed slurry into a high-concentration slurry. Specifically, the first abrasive disc 21 and the second abrasive disc 22 are cylindrical, and the first abrasive disc 21 is arranged above the second abrasive disc 22 and is a fixed disc. The abrasive mechanism 20 also includes a rotating motor, which is arranged at the bottom of the second abrasive disc 22 and is used to drive the second abrasive disc 22 to rotate. Specifically, the materials of the first abrasive disc 21 and the second abrasive disc 22 are rock, ceramic or metal.

[0041] Further, see Figure 2 The abrasive mechanism 20 further includes a material blocking groove 221, which is disposed on the grinding surface of the second abrasive disc 22 and is provided with a plurality of material blocking grooves 221 at intervals in the axial direction around the central axis of the second abrasive disc 22 and along the radial direction of the second abrasive disc 22. The grinding surface and the opening edge of the material blocking groove 221 are used to cooperate with the grinding surface of the first abrasive disc 21 to shear and knead the mixed slurry. After the mixed slurry enters the abrasive cavity, a portion of the mixed slurry enters the material blocking groove 221. Under the high-speed rotation of the second abrasive disc 22, the opening edge of the material blocking groove 221 shears and breaks the mixed slurry at high speed; a portion of the mixed slurry does not enter the material blocking groove 221, and the first abrasive disc 21 and the second abrasive disc 22 cooperate to knead the mixed slurry.

[0042] Specifically, the material blocking groove 221 can be set to be a long strip or a circle, which is not limited here. In this embodiment, the material blocking groove 221 is a long oval and a fan-shaped cross setting. The material blocking groove 221 uses different shapes to set as many material blocking grooves 221 as possible on the grinding surface, thereby improving the shearing and crushing effect. After grinding, the mixed slurry forms a high-viscosity slurry, which is driven to the edge of the first abrasive disc 21 and the second abrasive disc 22 by the centrifugal force after the second abrasive disc 22 rotates and is discharged.

The injection pipe 33 is connected to the mixing tank 31, and the ingredients can be injected into the mixing tank 31 through the injection pipe 33. The stirring member 32 is rotatably arranged in the mixing tank 31 to stir the high-viscosity slurry and the ingredients to form a qualified thick slurry. Specifically, the ingredients include water and a smoke agent, and the water content of the high-viscosity slurry is between 60% and 75%, preferably 65% ​​to 70%, and the water content of the qualified thick slurry is maintained between 75% and 80%. In this embodiment, the stirring member 32 is configured as a stirring paddle, and the stirring paddle is arranged at the bottom of the mixing tank 31. A rotating motor is also arranged at the bottom of the stirring paddle to drive the stirring paddle to rotate.

[0044] Furthermore, the blending mechanism 30 also includes a weighing piece 34, which is disposed at the bottom of the blending tank 31 and is used to weigh the blending tank 31 so as to weigh the injected ingredients. The weighing piece 34 can first weigh the high-viscosity slurry entering the blending tank 31 and record the data, and then add the ingredients to the blending tank 31, and monitor the amount of ingredients added by observing the data changes of the weighing piece 34. In this embodiment, the weighing piece 34 is an electronic scale and is provided in plurality to increase the accuracy of weighing. After the tobacco leaves and water are stirred into a mixed slurry, most of the tobacco leaves can be ground into finer particles by controlling the grinding effect, but some tobacco fibers are still retained, avoiding the addition of additional fibers, reducing costs, and avoiding dust-related explosion safety hazards. Furthermore, since the mixed slurry has poor fluidity and needs to be extruded, the thick slurry preparation system also includes a first supply mechanism 40, which includes a first supply pipe 41, a first connecting pipe 42 and a second connecting pipe 43.

Specifically, the through hole 211 is circular and inclined from the outside to the inside on the first abrasive disc 21. The diameter of the second connecting pipe 43 is slightly larger than the diameter of the through hole 211, so that the mixed slurry has a certain pressure in the second connecting pipe 43, which facilitates the mixed slurry to enter the abrasive cavity.

[0045] Further, the first supply mechanism 40 further includes a first push screw 44, on which a first push paddle 441 is spirally arranged, the first push paddle 441 abuts against the inner wall of the first supply pipe 41, and the first push screw 44 is rotatably arranged in the first supply pipe 41 and drives the first push paddle 441 to rotate, so as to push the mixed slurry from the first connecting pipe 42 into the second connecting pipe 43. Specifically, the first supply mechanism 40 further includes a rotary motor, which is connected to the first push screw 44 and drives the first push screw 44 to rotate.

[0046] Furthermore, since the high-viscosity slurry has poor fluidity and needs to be extruded, the thick slurry preparation system also includes a second supply mechanism 50, which includes a second supply pipe 51, a receiving funnel 52 and a third connecting pipe 53. One end of the receiving funnel 52 is connected to the second supply pipe 51, and the other end is wrapped around the first abrasive disc 21 and the second abrasive disc 22 and is spaced apart from the first abrasive disc 21 and the second abrasive disc 22. The high-viscosity slurry can enter the receiving funnel 52 from the edge of the first abrasive disc 21 and the second abrasive disc 22, and the second supply pipe 51 and the mixing tank 31 are connected via the third connecting pipe 53.

[0047] Furthermore, the second supply mechanism 50 also includes a second push screw 54, on which a second push paddle 541 is spirally arranged, and the second push paddle 541 abuts against the inner wall of the second supply pipe 51.

Specifically, the second supply mechanism 50 also includes a rotary motor, which is connected to the second push screw 54 and drives the second push screw 54 to rotate. Specifically, the first supply pipe 41, the first push screw 44, the first push paddle 441, the second supply pipe 51, the second push screw 54 and the second push paddle 541 are all the same in structure, shape and size, saving mold opening costs.
