Description

Technical Field

[0001] This utility model relates to the field of reconstituted tobacco production technology, and in particular to a reconstituted tobacco cooling and impurity removal system. Background Technology

[0002] Reconstituted tobacco, also known as tobacco sheet, refers to a regenerated product made from waste materials such as tobacco stems, dust, and broken tobacco leaves discarded during cigarette manufacturing. It is produced in sheet or shred form and has an appearance similar to natural tobacco leaves, serving as a raw material in cigarette formulation. The application of reconstituted tobacco in cigarette manufacturing effectively improves the utilization rate of tobacco raw materials, reduces tar, enhances flavor, and regulates combustion rate, playing a vital role in Chinese-style cigarettes.

[0003] The reconstituted tobacco processing flow involves extracting tobacco raw materials into a suitable medium according to the formula requirements, followed by multiple solid-liquid separations to obtain an extract of a certain concentration and tobacco pulp fibers. The liquid phase undergoes multi-stage purification followed by evaporation and concentration to form a concentrate. The solid phase is then ground in a pulper to prepare a slurry. This slurry is quantitatively diluted and sent to a paper machine to form substrate sheets. Flavorings and fragrances are added to the concentrate, and the slurry is then dip-coated back onto the substrate in a coating machine to form thin sheets. Finally, after multiple drying, slicing, and packaging processes, the reconstituted tobacco product is formed.

[0004] Reconstituted tobacco leaves retain a certain temperature after drying, and moisture remains on the surface. The coating solution also retains some viscosity. Direct packaging poses quality risks such as caking and mold growth. Furthermore, if impurities enter the material during the process from slicing to packaging, serious quality problems can occur. Therefore, it is necessary to design a system that meets the cooling and impurity removal requirements of reconstituted tobacco leaves, ensuring product quality and safety. Utility Model Content

This system can cool the reconstituted tobacco leaves before packaging and boxing to avoid problems such as caking and mold growth. At the same time, it can also remove impurities from the reconstituted tobacco leaves before packaging and boxing.

[0006] This utility model provides a reconstituted tobacco cooling and impurity removal system, including a receiving device. The receiving device has a receiving port at the top and a discharge port at the bottom plate. A bidirectional conveyor belt is provided below the discharge port, with one end of the bidirectional conveyor belt connected to an impurity collection box.

[0027] Example

[0028] A reconstituted tobacco cooling and impurity removal system, such as Figure 1 As shown, the device includes a receiving device 1, with a receiving port 102 at the top and a material outlet at the middle of the side wall or the side opposite to the receiving port 102. A discharge port 103 is located at the bottom of the receiving device 1, and a bidirectional conveyor belt 2 is installed below the discharge port 103. One end of the bidirectional conveyor belt 2 is connected to an impurity collection box 3. The material outlet is connected to a first air duct 18, which is connected to the inlet of the discharge device 4. The exhaust port of the discharge device 4 is connected to a second air duct, which is connected to a dust collector 12. The dust collector 12 is connected to a third air duct, which is connected to the suction port of a variable frequency fan 14. A storage tank conveyor belt 5 is located below the discharge port of the discharge device 4, and the storage tank conveyor belt 5 is connected to a tobacco storage tank unit. A discharge conveyor belt 9 is located at the discharge port of the tobacco storage tank unit.

[0029] The other end of the bidirectional conveyor belt 2 is equipped with a discharge conveyor belt 9. When the reconstituted tobacco leaves do not need to be cooled, the reconstituted tobacco leaves are discharged directly from the discharge port 103 of the receiving device 1 and transported directly to the discharge conveyor belt 9 via the bidirectional conveyor belt 2.

[0030] The tobacco storage unit includes a distribution crane 6, a spreading crane 7, and a storage cabinet 8. The distribution crane 6 is connected to the inlet conveyor belt 5 and the spreading crane 7. The storage cabinet 8 is located below the spreading crane 7. The outlet of the storage cabinet 8 is equipped with an outlet conveyor belt 9. The reconstituted tobacco leaves after impurity removal and cooling are transported to the packaging process for packaging via the outlet conveyor belt 9.

[0031] A negative pressure detection sensor is installed on the first duct 18, a fire damper 11 is installed on the second duct, and an air regulating valve 13 is installed on the third duct. The outlet of the variable frequency fan 14 is connected to the fourth duct, which is equipped with a silencer 15 and a windproof cap 16. The system also includes a first control unit. The negative pressure detection sensor, air regulating valve 13, variable frequency fan 14, and the first control unit are connected. The first control unit controls the variable frequency fan 14 and the air regulating valve 13 to regulate the negative pressure airflow generated inside the receiving device 1.

[0032] The first duct 18 introduces the dust-laden gas from the receiving device 1 into the dust collector 12 via the second duct. Dust particles are separated from the gas and discharged after passing through the variable frequency fan 14, silencer 15, and windproof cap 16. The dust outlet of the dust collector 12 is connected to the dust collection device 17 via a pipe. After separating the dust from the airflow, the dust collector 12 transports the dust to the dust collection device 17 for storage and collection.

[0033] like Figure 2 and Figure 3As shown, the receiving device 1 includes a hopper 101, which is a cuboid structure. A receiving port 102 is located at the top of the hopper 101. The cross-section of the receiving port 102 is rectangular or concave, and its shape matches the shape and specifications of the feeding conveyor belt 10 and the amount of material being conveyed. The connection between the receiving port 102 and the hopper 101 is smooth. A material outlet is located on the side wall of the hopper 101, and the material outlet is connected to the first air duct 18. A discharge port 103 is located at the bottom of the hopper 101. Rotatable tilting plates 104 are installed on the long sides of both sides of the discharge port 103. The tilting plates 104 are rotatably connected to the hopper 101 via a rotating shaft 108. The tilting plates 104 are connected to a power unit via a first connecting rod 106 and a second connecting rod 107, and the power unit provides power for the rotation of the tilting plates 104. Each tilting plate 104 can be equipped with one power unit at one end, and the power units for the two tilting plates 104 are respectively located on two opposite side walls of the hopper 101. A bidirectional conveyor belt 2 is installed below the material discharge port 103.

[0034] like Figure 4 As shown, the power unit includes a protective cover 105 fixedly and inclinedly mounted on the side wall of the hopper 101. A drive motor 1051 is installed inside the protective cover 105. The drive motor 1051 is fixedly connected to a transmission shaft 1052, which is detachably connected to a screw 1053. A nut 1054, which mates with the screw 1053, is fitted onto the screw 1053. One end of a first connecting rod 106 is fixedly connected to the nut 1054, and the end of the first connecting rod 106 away from the nut 1054 extends outside the protective cover 105 and is rotatably connected to a second connecting rod 107 via a rotating component 109. The second connecting rod 107 is fixedly connected to a tilting plate 104. The power unit drives the tilting plate 104 to rotate around a rotating shaft 108, thereby adjusting the air inlet area at the discharge port 103. The rotating component 109 can be a shaft, bearing, hinge, universal joint, or similar structure. The drive motor 1051 is also connected to a first control unit.

[0035] When it is necessary to increase the air intake area of ​​the bottom discharge port 103, the first control unit controls the drive motor 1051 to drive the screw 1053 to rotate, the nut 1054 moves upward, and the first connecting rod 106 drives the second connecting rod 107 to rotate, thereby causing the flip plate 104 to rotate around the rotating shaft 108, increasing the opening angle to a maximum of 90° (i.e., the flip plate 104 is perpendicular to the discharge port 103); when it is necessary to decrease the air intake area of ​​the bottom discharge port 103, the first control unit controls the drive motor 1051 to drive the screw 1053 to rotate in the opposite direction, the nut 1054 moves downward, and the first connecting rod 106 drives the second connecting rod 107 to rotate, causing the flip plate 104 to rotate in the opposite direction around the rotating shaft 108, decreasing the opening angle to a minimum of 0° (i.e., the flip plate 104 is parallel to the discharge port 103).

[0036] The screw 1053 is detachably connected to the drive shaft 1052. A slot 1055 can be provided at one end of the screw 1053, and a protruding locking block that mates with the slot 1055 is provided at the end of the drive shaft 1052. The slot 1055 and the locking block are used to lock the screw 1053 and the drive shaft 1052 together, and the connection is secured with a fixing screw 1056. The fixing screw 1056 passes through the slot 1055 and the locking block and connects to the fixing nut 1057. The screw 1053 of the power unit is easy to disassemble and maintain. The drive motor 1051 drives the screw 1053 to move the nut 1054, so that the rotation angle of the flip plate 104 can be stably and precisely controlled.

[0037] In this embodiment, the feeding device 4 adopts a tangential feeding device. The main structure of the tangential feeding device consists of a feed inlet, a distributor body, an exhaust port, and a discharge valve. Its principle is as follows: when the variable frequency fan 14 forces air in, it creates a negative pressure at the exhaust port through the pipeline. Due to the suction effect of the exhaust port, a negative pressure vacuum is formed in the distributor body. At this time, the reconstituted tobacco and air enter the distributor body at a high speed under the negative pressure suction effect of the feed inlet. The reconstituted tobacco is pushed against the arc wall under the action of centrifugal force, changing its direction of movement. Under the action of gravity, it sinks into the discharge valve. As the discharge valve blades rotate, the reconstituted tobacco is discharged. At the same time, the dust-laden air enters the dust collector 12 through the second air duct after the exhaust port to separate the dust, passes through the variable frequency fan 14 and the silencer 15, and is finally discharged through the windproof cap 16.

[0038] After impurity removal, the reconstituted tobacco leaves fall from the discharge port of the feeding device 4 to the conveyor belt 5 of the storage tank and reach the distribution trolley 6. The distribution trolley 6 reciprocates laterally to the distribution trolley 7. The distribution trolley 7 stops at a suitable position in the tobacco storage tank 8. The reconstituted tobacco leaves are distributed to the tobacco storage tank 8 by the distribution trolley 7. The bottom belt motor of the tobacco storage tank 8 is continuously running, and the reconstituted tobacco leaves are fed in and out at the same time. The residence time of the reconstituted tobacco leaves in the tobacco storage tank 8 is adjusted by the distribution position of the distribution trolley 7 and the bottom belt motor.

[0039] A discharge conveyor belt 9 is installed at the discharge port of the tobacco storage unit to transport the cooled reconstituted tobacco leaves to the packaging process for packaging. A temperature sensor is installed on the discharge conveyor belt 9 to detect the temperature of the cooled reconstituted tobacco leaves. The temperature sensor is connected to a second control unit, which is connected to the bottom belt motor of the storage unit 8. When the temperature of the reconstituted tobacco leaves detected by the temperature sensor is higher than the set upper temperature limit, the temperature sensor feeds back to the second control unit, which reduces the frequency of the bottom belt motor, extending the cooling time of the reconstituted tobacco leaves in the storage unit 8. When the temperature of the reconstituted tobacco leaves is lower than the set upper temperature limit, the temperature sensor feeds back to the second control unit, which increases the frequency of the bottom belt motor, reducing the cooling time of the reconstituted tobacco leaves in the storage unit 8.

[0040] The working principle of the reconstituted tobacco cooling and impurity removal system provided by this utility model is as follows:

[0041] When reconstituted tobacco leaves need to be cooled and cleaned before the baling process:

[0042] The dust collector 12, air regulating valve 13, and variable frequency fan 14 are started. The airflow is adjusted by the variable frequency fan 14 and air regulating valve 13 according to the type of impurities to be removed. The rotation angle of the tilting plate 104 is adjusted by the power device, and the air inlet area at the discharge port 103 of the receiving device 1 is adjusted. The reconstituted tobacco leaves are transported to the discharge port 102 of the receiving device 1 by the feeding conveyor belt 10. Under the action of gravity and negative pressure airflow, they enter the hopper 101. Under the action of negative pressure airflow, the reconstituted tobacco leaves enter the first air duct 18 and reach the discharge device 4. Impurities with a density greater than that of the reconstituted tobacco leaves reach the bidirectional conveyor belt 2 through the discharge port 103 under the action of gravity, and are sent to the impurity collection box 3 by the bidirectional conveyor belt 2.

[0043] After being conveyed to the unloading device 4 via the first air duct 18, the reconstituted tobacco leaves fall into the tobacco storage unit. The dust-laden air from the unloading device 4 enters the dust collector 12 through the exhaust port via the second air duct to separate the dust. After passing through the variable frequency fan 14 and the silencer 15, the dust is exhausted through the windproof cap 16. After being cooled in the storage tank 8, the reconstituted tobacco leaves go from the discharge port to the discharge conveyor belt 9 and enter the packaging process.

[0044] When reconstituted tobacco does not require cooling and impurity removal:

[0045] The variable frequency fan 14 does not provide negative pressure power. The dust collector 12, the air regulating valve 13 and the variable frequency fan 14 are closed. The reconstituted tobacco leaves fall directly onto the bidirectional conveyor belt 2 via the receiving device 1. The bidirectional conveyor belt 2 directly transports the reconstituted tobacco leaves to the discharge conveyor belt 9 and enters the packaging process.

[0046] The system provided by this utility model can flexibly select the circuit to meet the needs of different scenarios; it can separate fine dust and impurities, effectively ensuring product quality and working environment; it can realize automatic feedback control of reconstituted tobacco temperature, effectively avoiding quality risks such as caking and mold caused by high material temperature and insufficient moisture loss.

[0047] The receiving device provided by this utility model can separate fine dust and denser impurities by using the principle of air separation while conveying reconstituted tobacco leaves. The separated fine dust is collected by a dust collector, and the denser impurities are carried into the impurity collection box by a bidirectional conveyor belt. The air separation effect can be controlled by adjusting the drive motor of the variable frequency fan, the air regulating valve, and the tilting plate.

[0048] The system provided by this utility model utilizes the wind-powered conveying process and the cooling of reconstituted tobacco leaves in a tobacco storage tank. The temperature of the material is detected by a temperature sensor on the discharge conveyor belt and fed back to the control unit. By controlling the frequency of the motor at the bottom of the tobacco storage tank, the residence time of the reconstituted tobacco leaves in the tobacco storage tank is adjusted, thereby regulating the cooling effect.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
