Description

Technical Field

[0001] This utility model relates to the field of tobacco processing technology, and in particular to a tobacco loosening device. Background Technology

[0002] During the cigarette making process, the length distribution of tobacco shreds is extremely uneven. Overly long shreds tend to entangle and curl together during processing, making them difficult to mix evenly with other tobacco shreds. Furthermore, under the influence of factors such as temperature, humidity, pressure, and storage conditions, they are prone to clumping, leading to increased breakage rate, decreased filling value, and increased energy consumption during subsequent processing. Therefore, it is necessary to loosen the tobacco shreds beforehand.

[0003] In existing technologies, loosening tobacco shreds mainly employs mechanical methods, with equipment such as mechanical vibrating screens or drum-type loosening devices. These devices disperse tobacco shreds through physical contact, i.e., contact mechanical action, but they suffer from drawbacks such as mechanical damage to the tobacco shreds and wear and tear on components due to long-term friction. These drawbacks may further affect the effective solution to problems such as tobacco clumping. Utility Model Content

[0006] The bottom side of the cylinder is provided with a feed inlet, and the top side of the cylinder is provided with a discharge outlet; the bottom of the cylinder is provided with a pneumatic port, and the side wall of the cylinder is provided with a first airflow section and a second airflow section in sequence along the axial direction of the cylinder; the pneumatic port, the first airflow section, and the second airflow section are respectively connected to an airflow generating device; the airflow generating device can deliver airflow moving along the axial direction of the cylinder into the cylinder through the pneumatic port; the airflow generating device can deliver rotating airflow that rotates circumferentially relative to the axial direction of the cylinder into the cylinder through the first airflow section and the second airflow section, and the rotating airflow generated by the first airflow section and the rotating airflow generated by the second airflow section have opposite directions of rotation.

[0007] As a further improvement to the above technical solution, the first airflow section includes a first airflow hole, which is disposed on the side wall of the cylinder, and the opening direction of the first airflow hole is set at an angle to the radial direction of the cylinder; the second airflow section includes a second airflow hole, which is disposed on the side wall of the cylinder, and the opening direction of the second airflow hole is set at an angle to the radial direction of the cylinder.

[0008] As a further improvement to the above technical solution, the first airflow hole and the second airflow hole are respectively provided in multiple circumferential directions relative to the cylinder.

[0009] As a further improvement to the above technical solution, the bottom and top of the cylinder are respectively connected by a first conical section and a second conical section. The diameter of the ends of the first conical section and the second conical section away from the center of the cylinder is smaller than the diameter of the ends of the first conical section and the second conical section near the center of the cylinder. The pneumatic port is opened on the bottom of the first conical section, the feed port is set on the conical surface near the bottom of the first conical section, and the discharge port is set on the conical surface near the bottom of the second conical section.

[0010] As a further improvement to the above technical solution, the first airflow hole is disposed on the conical surface of the first conical section, and the second airflow hole is disposed on the conical surface near the second conical section. The opening directions of the first airflow hole and the second airflow hole are set at an angle to the cross-section of the cylinder and are deflected in opposite directions.

[0011] As a further improvement to the above technical solution, the feed inlet and the discharge outlet are respectively externally provided with a feed hopper and a discharge hopper.

[0012] As a further improvement to the above technical solution, the bottom and side of the feeding hopper are respectively connected to the edge of the feeding port, and the bottom of the feeding hopper is horizontally set.

[0013] As a further improvement to the above technical solution, the discharge hopper has a side-closed discharge channel, which is connected to the edge of the discharge port.

[0014] As a further improvement to the above technical solution, the end of the discharge channel away from the discharge port is bent towards the center of the cylinder.

[0015] As a further improvement to the above technical solution, pressure relief grooves are evenly distributed on the side wall of the discharge channel away from the bottom of the cylinder.

[0016] Compared with related technologies, the beneficial effects of this utility model are: The tobacco loosening device provided by this utility model, when it is necessary to loosen clumps of tobacco material, firstly activates the airflow generating device connected to the pneumatic inlet, the first airflow section, and the second airflow section on the cylinder. The airflow generating device is the power source of the entire loosening process. After its activation, it delivers two different forms of airflow into the cylinder. On one hand, it delivers a linear airflow that moves stably along the axis of the cylinder, providing the basic power for the axial movement of the tobacco material within the cylinder. On the other hand, through the first and second airflow sections, it can deliver a rotating airflow that rotates circumferentially relative to the axis of the cylinder and in the opposite direction to the rotation.

[0017] After the airflow generating equipment is started and generates the required airflow, the tobacco material to be loosened is conveyed into the cylinder through the feed inlet near the pneumatic inlet. Upon entering the cylinder, the tobacco material is first propelled along the cylinder's axis by the airflow output from the pneumatic inlet. During this movement, the tobacco material encounters the rotating airflow generated by the first airflow section. As the tobacco material enters the rotating airflow area, it begins to rotate with the airflow. This rotational motion causes the originally clumped tobacco material to be dispersed by a dispersing force, gradually breaking it apart.

[0018] The tobacco material then continues to move and encounters a rotating airflow generated by the second airflow section, which rotates in the opposite direction to the first airflow section. When the opposing rotating airflow and the forward rotating airflow act together on the tobacco material, a pulling effect is produced. This pulling effect can further break down the agglomeration structure between the tobacco materials, causing them to rub against each other, collide, and rotate within the cylinder, thereby achieving more thorough separation.

[0019] During the loosening process, the clumps of tobacco that are not yet fully loosened, being heavier, are continuously rotated and loosened by the rotating airflow inside the cylinder. Meanwhile, the loosened tobacco, being lighter, is gradually pushed towards the discharge port of the cylinder by the airflow from the pneumatic inlet. With the continued pushing of the airflow, the loosened tobacco is eventually discharged from the cylinder through the discharge port.

[0020] Through the meticulous and orderly processing of tobacco shreds described above, this tobacco loosening equipment can fully realize the loosening of tobacco shreds. This efficient processing method not only significantly improves the processing quality of tobacco shreds, making the length distribution of tobacco shreds more uniform and the shape more loose for subsequent processing, but also greatly improves the processing efficiency of tobacco shreds, reduces processing time and energy consumption, and provides strong support for the optimization of cigarette manufacturing technology.

[0030] Combination Figure 1 , Figure 2 As shown, an embodiment of this utility model provides a tobacco loosening device, including a cylinder 100.

[0031] The cylinder 100 has a feed inlet 110 on its bottom side and a discharge outlet 120 on its top side. A pneumatic inlet 130 is located at the bottom of the cylinder 100. A first airflow section 140 and a second airflow section 150 are sequentially arranged on the side wall of the cylinder 100 along its axial direction. The pneumatic inlet 130, the first airflow section 140, and the second airflow section 150 are respectively connected to an airflow generating device. The airflow generating device can deliver airflow moving along the axial direction of the cylinder 100 into the cylinder 100 through the pneumatic inlet 130. The airflow generating device can also deliver rotating airflow that rotates circumferentially relative to the axis of the cylinder 100 into the cylinder 100 through the first airflow section 140 and the second airflow section 150. The rotating airflow generated by the first airflow section 140 and the rotating airflow generated by the second airflow section 150 have opposite rotation directions. Figure 2 The arrow in the diagram illustrates this.

[0032] The tobacco loosening equipment provided in this embodiment, when it is necessary to loosen clumps of tobacco material, firstly activates the airflow generating device connected to the pneumatic port 130, the first airflow section 140, and the second airflow section 150 on the cylinder 100. The airflow generating device is the power source of the entire loosening process. After its activation, it delivers two different forms of airflow into the cylinder 100. On one hand, it delivers a linear airflow that moves stably along the axis of the cylinder 100 into the cylinder 100. This linear airflow provides the basic power for the axial movement of the tobacco material within the cylinder 100. On the other hand, through the first airflow section 140 and the second airflow section 150, it can deliver a rotating airflow that rotates circumferentially relative to the axis of the cylinder 100 and in the opposite direction into the cylinder 100.

[0033] After the airflow generating device is started and generates the required airflow, the tobacco material to be loosened is conveyed into the cylinder 100 through the feed port 110 near the pneumatic port 130. Upon entering the cylinder 100, the tobacco material is first pushed along the axis of the cylinder 100 by the airflow output from the pneumatic port 130. During this movement, the tobacco material first encounters the rotating airflow generated by the first airflow section 140. When the tobacco material enters the rotating airflow area, it begins to rotate with the airflow. This rotational motion causes the originally clumped tobacco material to be dispersed by a dispersing force, gradually breaking it apart.

[0034] The tobacco material then continues to move and encounters a rotating airflow generated by the second airflow section 150, which rotates in the opposite direction to the first airflow section 140. When the opposing rotating airflow and the forward rotating airflow act together on the tobacco material, a pulling effect is generated. This pulling effect can further break down the agglomeration structure between the tobacco materials, causing the tobacco materials to rub against each other, collide, and rotate within the cylinder 100, thereby achieving more thorough separation.

[0035] During the loosening process, the clumps of tobacco material that are not yet fully loosened, being heavier, will be continuously rotated and loosened by the rotating airflow within the cylinder 100. Meanwhile, the loosened tobacco material, being lighter, will gradually move towards the discharge port 120 of the cylinder 100 under the pushing force of the airflow from the pneumatic port 130. With the continued pushing of the airflow, the loosened tobacco material will eventually be discharged from the cylinder 100 through the discharge port 120.

[0036] In some specific embodiments, the first airflow section 140 includes a first airflow hole 141, which is disposed on the side wall of the cylinder 100, such as... Figure 4 As shown, the opening direction of the first airflow hole 141 is angularly arranged with respect to the radial direction of the cylinder 100; the second airflow section 150 includes a second airflow hole 151, which is disposed on the side wall of the cylinder 100, such as... Figure 6 As shown, the opening direction of the second airflow hole 151 is set at an angle to the radial direction of the cylinder 100; specifically, the above-mentioned restriction on the opening direction of the first airflow hole 141 and the second airflow hole 151 is of great significance. When the airflow generating device is started, the airflow will enter the interior of the cylinder 100 through the first airflow hole 141 and the second airflow hole 151. Since the opening direction of the first airflow hole 141 and the second airflow hole 151 is at an angle to the radial direction of the cylinder 100, when the airflow is ejected from the hole, it will not directly and vertically impact the interior space of the cylinder 100, but will impact the inner wall of the cylinder 100 at a certain angle. When the airflow impacts the inner wall of the cylinder 100, the inner wall acts like a guide plate, guiding the airflow. Under the guiding effect of the inner wall of the cylinder 100, the originally linearly moving airflow will change its direction of movement, thereby forming a rotating airflow.

[0037] This method of creating a rotating airflow through a specific angled airflow hole design has many advantages. Its operation is highly stable and reliable, and airflow turbulence will not occur due to minor external disturbances or slight vibrations within the equipment itself. Furthermore, the resulting rotating airflow can continuously and uniformly act on the tobacco material within the cylinder 100, providing stable and effective power for the loosening of the tobacco material, thus helping to improve the processing efficiency and quality of the entire tobacco loosening equipment.

[0038] In some specific embodiments, multiple first airflow holes 141 and second airflow holes 151 are evenly distributed circumferentially relative to the cylinder 100. The reason for this multiple airflow hole arrangement is that the simultaneous action of multiple airflow holes can generate a stronger and more stable airflow effect. When the airflow generating device is activated, the airflow enters the cylinder 100 through these evenly distributed first airflow holes 141 and second airflow holes 151. The airflow ejected from each airflow hole has a certain direction and velocity. Because they are evenly distributed circumferentially, these airflows can form a relatively complete and uniform airflow field inside the cylinder 100. In this airflow field, the airflows influence and complement each other, thereby facilitating the formation of a stable rotating airflow within the cylinder 100.

[0039] A stable rotating airflow is crucial for the loosening of tobacco materials. When the tobacco materials enter the cylinder 100, they are impacted and driven by the rotating airflow. This airflow exerts force on the tobacco materials from multiple directions, causing them to continuously tumble, rotate, and rub against each other within the cylinder 100. This action effectively breaks down the agglomerate structure of the tobacco materials, gradually loosening any clumps. Furthermore, a stable rotating airflow ensures a uniform and continuous force on the tobacco materials, preventing localized excessive or insufficient force, thus ensuring the reliability of the loosening process and improving the overall processing quality and efficiency of the tobacco loosening equipment.

[0040] In some specific embodiments, the bottom and top of the cylinder 100 are respectively connected by a first conical section 160 and a second conical section 170. The diameter of the ends of the first conical section 160 and the second conical section 170 away from the center of the cylinder 100 is smaller than the diameter of the ends of the first conical section 160 and the second conical section 170 near the center of the cylinder 100. The pneumatic port 130 is opened on the conical bottom of the first conical section 160, the feed port 110 is located on the conical surface near the conical bottom of the first conical section 160, and the discharge port 120 is located on the conical surface near the conical bottom of the second conical section 170. This structural design has many significant advantages. It can effectively reduce the dead angles of airflow within the cylinder 100, that is, the dead angles of loosening processing. In the traditional cylinder 100 structure, there may be some areas where airflow cannot reach sufficiently, causing material to accumulate in these areas and preventing effective loosening processing. In this embodiment, the special shapes of the first conical section 160 and the second conical section 170, as well as the reasonable positioning of the pneumatic port 130, the feed port 110 and the discharge port 120, enable the airflow to form a more uniform and comprehensive flow within the cylinder 100, reducing the generation of dead zones.

[0041] This avoids material accumulation within the cylinder 100, meaning all tobacco materials fed into the cylinder 100 can fully participate in the loosening process. Material accumulation prevents localized overheating or uneven processing, ensuring thorough processing of the tobacco materials. Furthermore, the reduction of dead zones and accumulation leads to smoother material movement and more efficient processing, thus ensuring higher processing efficiency.

[0042] In some specific embodiments, the first airflow hole 141 is disposed on the conical surface of the first conical section 160, and the second airflow hole 151 is disposed on the conical surface near the second conical section 170. The opening directions of the first airflow hole 141 and the second airflow hole 151 are set at an angle to the cross-section of the cylinder 100 and are deflected in opposite directions. Under such airflow action, the clump of tobacco material will be significantly pushed. Specifically, under the combined action of the rotational drive of the first airflow hole 141 and the second airflow hole 151, the clump of tobacco material will be pushed towards the center of the cylinder 100 simultaneously. The rotating airflow generated by the first airflow hole 141 drives a portion of the tobacco material towards the center, while the rotating airflow generated by the second airflow hole 151 drives another portion of the tobacco material to converge towards the center from the opposite but opposite direction.

[0043] When two portions of tobacco material, driven by different rotating airflows, approach the center of the cylinder 100, they easily collide and rub against each other. This collision and friction can generate a strong force, further disrupting the agglomeration structure between the tobacco materials. The originally tightly bound tobacco clumps will gradually loosen under the action of collision and friction, making the tobacco material more dispersed and uniform in shape.

[0044] Compared to traditional airflow hole designs, this design more effectively promotes collision and friction among the tobacco shreds, significantly improving the efficiency of loosening the tobacco shreds. Under the same time and airflow conditions, this type of tobacco loosening equipment can process more tobacco shreds and achieve a higher degree of loosening, providing higher-quality tobacco raw materials for subsequent cigarette processing steps.

[0045] In some specific embodiments, the feed inlet 110 and the discharge outlet 120 are respectively externally provided with a feed hopper 111 and a discharge hopper 121, which facilitates the process of conveying tobacco into the cylinder 100 and discharging it from the discharge outlet 120, and ensures the efficiency of material conveying and discharge.

[0046] like Figure 3As shown, in some specific embodiments, the bottom and sides of the feed hopper 111 are connected to the edge of the feed inlet 110, and the bottom of the feed hopper 111 is horizontal. From the perspective of the feeding process, the design of the feed hopper 111 fully considers the characteristics of tobacco and the convenience of conveying. The feed hopper 111 typically adopts a suitable shape and size, with a large opening and a certain degree of inclination. This design facilitates the operator to quickly and accurately pour the tobacco into it. After the tobacco enters the feed hopper 111, because the feed hopper 111 is connected to the feed inlet 110, the tobacco will slide smoothly along the inner wall of the feed hopper 111 into the feed inlet 110 under its own gravity, and then enter the cylinder 100. The existence of the feed hopper 111 is like a guiding channel, which can effectively prevent the tobacco from scattering or clogging during the conveying process into the cylinder 100, ensuring that the tobacco can enter the cylinder 100 stably and continuously, providing a stable material supply for subsequent processing.

[0047] like Figure 5 As shown, in some specific embodiments, the discharge hopper 121 has a side-closed discharge channel 122, which is connected to the edge of the discharge port 120; this can prevent tobacco from splashing everywhere during the discharge process and ensure that the tobacco can be discharged from the equipment in a concentrated and orderly manner.

[0048] In some specific embodiments, the end of the discharge channel 122 away from the discharge port 120 is bent towards the center of the cylinder 100, which facilitates downward guidance of the tobacco material during discharge, makes it easier for operators to collect and collect the material, and improves work efficiency.

[0049] In some specific embodiments, pressure relief grooves 123 are evenly distributed on the side wall of the discharge channel 122 away from the bottom of the cylinder 100, so as to divert the airflow output from the discharge channel 122, avoid the tobacco material being pressed against the upper inner wall of the discharge channel 122 due to excessive air pressure at its position, and ensure the smooth discharge of material.
