Description

Technical Field

[0001] This application relates to the field of tobacco processing technology, and in particular to a granulation apparatus. Background Technology

[0002] Functional particles are typically embedded in filter tips in various forms. Through selective adsorption or catalysis, they can effectively meet the needs of cigarette products for reducing tar, cooling smoke, and enhancing sensory aroma, thereby improving the consumer's smoking experience. Therefore, improving the refining and processing level of natural flavor raw materials, especially breaking through the bottlenecks in the manufacturing and processing of functional particles from natural flavor raw materials, can effectively promote technological innovation and industrial upgrading in the refining of natural flavor raw materials. Furthermore, it can also guarantee and enhance the differentiated competitiveness of local tobacco products.

[0003] In the refining of functional granules from natural fragrance raw materials, the granulation process is crucial to the production efficiency and product quality of functional granules. However, in traditional extrusion granulators, the raw material easily clogs the extrusion orifice during extrusion, causing blockage and affecting granulation efficiency. Utility Model Content

[0004] Therefore, it is necessary to provide a granulation device that improves granulation efficiency to address the aforementioned technical problems.

[0005] The embodiments of this application provide a granulation apparatus, including an extrusion mechanism and a first driving mechanism. The extrusion mechanism includes an annular mesh and an extrusion cavity formed by the annular mesh. The annular mesh is provided with a plurality of extrusion holes communicating with the inside and outside of the extrusion cavity, and the diameter of the extrusion holes gradually increases along the direction away from the extrusion cavity. The extrusion cavity is provided with a first rotating shaft and planetary gears rotatably connected to the first rotating shaft. The planetary gears include a second rotating shaft. The first driving mechanism includes a first driving part and a second driving part, both of which are connected to the planetary gears. The first driving part is used to drive the planetary gears to rotate around the second rotating shaft, and the second driving part is used to drive the planetary gears to move in a ring around the first rotating shaft in the extrusion cavity.

[0006] In one embodiment, the device further includes: a pretreatment mechanism connected to the extrusion mechanism, the pretreatment mechanism including a housing, a leveling cavity provided inside the housing, two leveling rollers arranged side by side in the leveling cavity, a gap being formed between the two leveling rollers; and a second drive mechanism connected to the leveling rollers, the second drive mechanism being used to drive the two leveling rollers to rotate in opposite directions.

[0007] In one embodiment, the device further includes: a crushing chamber located below the leveling chamber is provided inside the housing, and two crushing rollers are arranged side by side inside the crushing chamber, with a gap between the two crushing rollers; the granulation device also includes a third driving mechanism connected to the crushing rollers, the third driving mechanism being used to drive the two crushing rollers to rotate in opposite directions.

[0008] In one embodiment, the crushing rollers are further provided with a plurality of mesh holes on their outer peripheral surface.

[0009] In one embodiment, the aperture of the mesh is larger than the aperture of the extrusion hole.

[0010] In one embodiment, the crushing chamber is located above the extrusion mechanism.

[0011] In one embodiment, the housing is further provided with a transfer chamber, which connects the crushing chamber and the extrusion chamber, and a first guide plate extending toward the extrusion chamber is provided in the transfer chamber.

[0012] In one embodiment, the first guide plate is further inclined downward along the direction close to the extrusion chamber.

[0013] In one embodiment, the housing is further provided with a feeding chamber located above the leveling chamber, and an opening communicating with the inside and outside of the feeding chamber is provided on the top of the housing.

[0014] In one embodiment, the planetary gear also includes a plurality of pressure plates connected to the second rotating shaft, the plurality of pressure plates being arranged at equal angles around the second rotating shaft.

[0015] The granulation apparatus provided in this application gradually increases the diameter of the extrusion orifice along the direction away from the extrusion chamber. This gradually increasing orifice size reduces the friction between the material and the orifice during extrusion, thereby reducing material adhesion to the orifice walls, minimizing orifice blockage, and improving granulation efficiency. A first driving mechanism drives the planetary gears to rotate and revolve within the extrusion chamber. The revolve ensures full contact between the planetary gears and the inner circumferential surface of the annular mesh, fully utilizing the area of ​​the annular mesh's inner circumferential surface and thus improving granulation efficiency. The rotation of the planetary gears, on the one hand, drives the material to flow towards the extrusion orifice of the annular mesh, ensuring material supply; on the other hand, it reduces friction between the planetary gears and the annular mesh, increasing the extrusion pressure on the material, increasing the extrusion speed, and further improving granulation efficiency.

Therefore, this application is not limited to the specific embodiments disclosed below.

[0030] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

It should be noted that the z-direction in the drawings refers to the vertical direction. In the drawings, for ease of drawing, the dimensions are not necessarily proportional to the actual dimensions.

[0036] Please refer to Figures 1 to 3 , Figure 1 This is a front view structural schematic diagram of a granulation apparatus according to some embodiments of this application. Figure 2 An example is shown Figure 1 A cross-sectional view of the granulation device from the perspective of AA. Figure 3 An example is shown Figure 2 A partially enlarged schematic diagram of the granulation device at position B.

[0037] like Figures 1 to 3 As shown, an embodiment of this application provides a granulation apparatus 10, including an extrusion mechanism 100 and a first drive mechanism (not shown). The extrusion mechanism 100 includes an annular mesh 110 and an extrusion cavity 120 formed by the annular mesh 110. The annular mesh 110 is provided with a plurality of extrusion holes 111 communicating with the inside and outside of the extrusion cavity 120, and the diameter of the extrusion holes 111 gradually increases in the direction away from the extrusion cavity 120. The extrusion cavity 120 is provided with a first rotating shaft 130 and a planetary gear 140 rotatably connected to the first rotating shaft 130. The planetary gear 140 includes a second rotating shaft 141. The first drive mechanism includes a first drive part and a second drive part, both connected to the planetary gear 140. The first drive part is used to drive the planetary gear 140 to rotate around the second rotating shaft 141, and the second drive part is used to drive the planetary gear 140 to move in a ring around the first rotating shaft 130 within the extrusion cavity 120.

[0038] Optionally, the cross-sectional shape of the annular mesh 110 is circular, and the axis formed by the centers of the annular mesh 110 is parallel to the horizontal plane. Multiple extrusion holes 111 are evenly distributed throughout the annular mesh 110. The central axis of each extrusion hole 111 intersects the axis formed by the centers of the annular mesh 110, meaning that the extrusion holes 111 extend away from the center of the annular mesh 110, and the diameter of the extrusion holes 111 increases with distance from the center of the annular mesh 110. The central axis of the first rotating shaft 130 coincides with the axis formed by the centers of the annular mesh 110, so that when the planetary gear 140 rotates around the first rotating shaft 130, the trajectory of the planetary gear 140 is a circular trajectory, and the circle of this circular trajectory coincides with the center of the annular mesh 110.

[0039] It should be noted that when the planetary gear 140 rotates around the second axis 141, the planetary gear 140 can be considered to be rotating on its own axis; when the planetary gear 140 rotates around the first axis 130, the planetary gear 140 can be considered to be revolving around the first axis 130. During both its rotation and revolution, the planetary gear 140 will rub against the inner circumferential surface of the annular mesh 110, and the extrusion force generated by the rotation will force the material in the extrusion chamber 120 out of the extrusion orifice 111. The material extruded from the extrusion orifice 111 falls under the influence of gravity and breaks into small particles of similar length. The cross-sectional shape of the small particles is determined by the cross-sectional shape of the extrusion orifice 111.

[0040] Optionally, both the first drive unit and the second drive unit are electric motors. Users can adjust the torque output of the first drive unit and the second drive unit to the planetary gear 140 to adjust the rotation and assembly speed of the planetary gear 140, thereby adjusting the size of the extruded particles.

[0041] Optionally, the extrusion chamber 120 may contain multiple planetary gears 140, which are arranged at equal angles around the first rotating shaft 130 to further improve the extrusion efficiency of the extruded particles. In this embodiment, two planetary gears 140 are provided in the extrusion chamber 120 as an example.

[0042] Optionally, the planetary gear 140 also includes multiple pressure plates 142 connected to the second rotating shaft 141. The multiple pressure plates 142 are arranged around the second rotating shaft 141 at equal angles. When the planetary gear 140 rotates and revolves, the end of the pressure plate 142 facing away from the second rotating shaft 141 will rub against the inner circumferential surface of the annular mesh 110, thereby pressing the material in the extrusion chamber 120 out of the extrusion hole 111.

[0043] Optionally, the extruded granules, after leaving the granulation device 10, can be embedded in cigarette filters as functional particles. The raw materials for the extruded granules can be activated carbon, plant-based materials, sugar alcohols, etc. Activated carbon granules processed by the granulation device 10 have a well-developed pore structure and a large specific surface area, effectively adsorbing harmful components such as nicotine and tar in cigarette smoke, reducing the content of harmful substances in mainstream cigarette smoke. Plant-based materials (such as coffee, grapefruit, etc.) granules processed by the granulation device 10 can impart a unique flavor to cigarettes. Sugar alcohols (such as xylitol, sorbitol, and isomaltitol) granules processed by the granulation device 10 can provide better cooling effects for the filter.

[0044] The granulation apparatus 10 of this application embodiment gradually increases the diameter of the extrusion orifice 111 in the direction away from the extrusion chamber 120. The gradually increasing orifice size reduces the friction between the material and the orifice during extrusion, thereby reducing the material sticking to the walls of the extrusion orifice 111, reducing clogging, and improving granulation efficiency. By setting a first driving mechanism to drive the planetary gear 140 to rotate and revolve within the extrusion chamber 120, the revolve allows the planetary gear 140 to fully contact the inner circumferential surface of the annular mesh 110, making full use of the area of ​​the inner circumferential surface of the annular mesh 110, thereby improving granulation efficiency. The rotation of the planetary gear 140 can, on the one hand, drive the material to flow towards the extrusion orifice 111 of the annular mesh 110, ensuring material supply, and on the other hand, reduce the friction between it and the annular mesh 110, increase the extrusion pressure on the material, increase the extrusion speed, and further improve granulation efficiency.

[0045] Please refer to Figures 1 to 5 , Figure 4 A side view schematic diagram of an example granulation device is shown. Figure 5 An example is shown Figure 4 A cross-sectional view of the granulation device in the diagram from a CC perspective.

[0046] like Figures 1 to 5 As shown, in some embodiments, the granulation apparatus 10 further includes a pretreatment mechanism 200 and a second drive mechanism 300. The pretreatment mechanism 200 is connected to the extrusion mechanism 100 and includes a housing 210. A leveling cavity 220 is provided within the housing 210, and two leveling rollers 221 arranged side-by-side are provided within the leveling cavity 221, with a gap between the two leveling rollers 221. The second drive mechanism 300 is connected to the leveling rollers 221 and is used to drive the two leveling rollers 221 to rotate in opposite directions.

[0047] Optionally, the material of the flattening rollers 221 includes stainless steel, and the outer peripheral surface of the flattening rollers 221 is smooth, used to extrude and stretch the raw material into sheet form.

[0048] Optionally, the housing 210 is also provided with a feeding chamber 230, which is located above the leveling chamber 220. An opening 231 is provided on the top of the housing 210 to connect the inside and outside of the feeding chamber 230.

[0049] Optionally, the feeding chamber 230 is provided with two second guide plates 232 on the side facing the leveling chamber 220. The two second guide plates 232 move closer to each other along the direction close to the leveling rollers 221, so that the two second guide plates 232 form a funnel-shaped structure. The bottom opening of the funnel-shaped structure faces the gap formed between the two leveling rollers 221. The powdered agglomerated raw material is fed into the feeding chamber 230 through the opening 231 and continues to fall under the action of gravity. During this process, it is guided by the second guide plates 232 and converges into the gap formed by the two leveling rollers 221 in the leveling chamber 220. Under the opposite rotation of the two leveling rollers 221, it is squeezed into a relatively dense and uniform sheet-like coarse pre-finished product.

[0050] Optionally, the second drive mechanism 300 is a motor. Users can adjust the density and specific shape of the rough pre-made semi-finished product after passing through the leveling cavity 220 by adjusting the distance between the two leveling rollers 221, the rotation speed of the leveling rollers 221, and the torque applied to the leveling rollers 221 by the second drive mechanism 300.

[0051] The granulation apparatus 10 of this application embodiment uses two second guide plates 232 arranged on the side of the feeding chamber 230 facing the leveling chamber 220 to gather the raw material into the gap between the two leveling rollers 221. By setting two opposing rotating leveling rollers 221 and making the outer peripheral surface of the leveling rollers 221 smooth, the powdery agglomerated raw material is transformed into a high-density, relatively uniform sheet-like coarse pre-finished product after being extruded and stretched by the leveling chamber 220, which facilitates subsequent processing.

[0052] In some embodiments, the housing 210 further includes a crushing chamber 240 located below the leveling chamber 220, and two crushing rollers 241 arranged side by side within the crushing chamber 240, with a gap between the two crushing rollers 241. The granulation device 10 also includes a third drive mechanism 400, which drives the two crushing rollers 241 to rotate in opposite directions.

[0053] Optionally, the crushing rollers 241 may be made of stainless steel and have multiple mesh openings (not shown) on their outer circumferential surface for extruding coarse pre-finished products into larger, more uniform fine pre-finished products with higher density.

[0054] Optionally, the leveling chamber 220 is provided with two third guide plates 222 on the side facing the crushing chamber 240. The two third guide plates 222 are brought closer together in the direction close to the crushing rollers 241, so that the two third guide plates 222 form a funnel-shaped structure. The bottom opening of the funnel-shaped structure faces the gap formed between the two crushing rollers 241. The sheet-like coarse pre-finished product falls under the action of gravity and is guided by the third guide plates 222 to converge at the gap formed by the two crushing rollers 241 in the crushing chamber 240. Under the opposite rotation of the two crushing rollers 241, it is extruded from the mesh on the crushing rollers 241 to form a larger, more uniform, fine pre-finished product with higher density.

[0055] Optionally, the third drive mechanism 400 is a motor. Users can adjust the density and specific shape of the fine pre-finished product after passing through the crushing chamber 240 by adjusting the distance between the two crushing rollers 241, the rotation speed of the crushing rollers 241, and the torque applied by the third drive mechanism 400 to the crushing rollers 241.

[0056] Optionally, the gap between the two crushing rollers 241 is smaller than the gap between the two leveling rollers 221, so that the sheet-like coarse pre-made semi-finished product can be squeezed out from the mesh on the crushing rollers 241 as much as possible when it is squeezed by the crushing rollers 241, so that the density of the squeezed large-particle refined pre-made semi-finished product is higher than that of the sheet-like coarse pre-made semi-finished product before being squeezed.

[0057] Optionally, the mesh aperture is larger than the extrusion aperture 111, so that the cross-sectional area of ​​the extruded particles produced by the extrusion mechanism 100 is smaller than the cross-sectional area of ​​the large particle fine pre-finished product after being processed by the crushing chamber 240, thereby making the density of the extruded particles produced by the extrusion mechanism 100 higher than the density of the large particle fine pre-finished product after being processed by the crushing chamber 240.

[0058] The granulation apparatus 10 of this application embodiment uses two third guide plates 222 on the side of the leveling chamber 220 facing the crushing chamber 240 to gather the sheet-like coarse pre-formed semi-finished product into the gap between the two crushing rollers 241. By setting two crushing rollers 241 that rotate in opposite directions and having mesh holes on their outer circumferential surfaces, the sheet-like coarse pre-formed semi-finished product is transformed into a larger, more uniform, finely granulated pre-formed semi-finished product after being squeezed and stretched by the crushing rollers 241, facilitating subsequent processing. By making the gap between the two crushing rollers 241 smaller than the gap between the two leveling rollers 221, and making the mesh hole diameter larger than the extrusion hole diameter 111, the particle size gradually decreases and the density gradually increases after the raw material is processed step by step through the leveling chamber 220, crushing chamber 240, and extrusion chamber 120, resulting in a more uniform and compact material.

[0059] In some embodiments, the crushing chamber 240 is located above the extrusion mechanism 100, and the large particle pre-finished semi-finished product processed by the extrusion mechanism 100 falls into the extrusion chamber 120 under the action of gravity.

[0060] Optionally, the extrusion mechanism 100 is located on one side of the pretreatment mechanism 200 in the horizontal direction, which can be understood as the extrusion mechanism 100 being located diagonally below the crushing chamber 240, rather than directly below it.

[0061] Optionally, the housing 210 also includes a transfer chamber 250, which connects the crushing chamber 240 and the extrusion chamber 120. The transfer chamber 250 contains a first guide plate 251 extending towards one side of the extrusion chamber 120. The first guide plate 251 gradually slopes downwards along the direction close to the extrusion chamber 120. Large-particle pre-finished semi-finished products processed by the crushing chamber 240 fall into the transfer chamber 250 under gravity and move obliquely downwards into the extrusion chamber 120 under the guidance of the first guide plate 251 for further processing.

[0062] The granulation apparatus 10 of this application embodiment provides a transfer chamber 250 below the crushing chamber 240, and uses a first guide plate 251 extending obliquely downward to guide large particle fine pre-made semi-finished products into the extrusion chamber 120 for further processing.

[0063] In summary, in the granulation apparatus 10 of this application embodiment, the powdered agglomerated raw material is first fed into the feeding chamber 230 through the opening 231 and continues to fall under gravity. During this process, it is guided by the second guide plate 232 and converges into the gap formed by the two flat rollers 221 in the flattening chamber 220. Under the opposite rotation of the two flat rollers 221, it is extruded into a sheet-like coarse pre-finished product with higher density and more uniformity. Then, the sheet-like coarse pre-finished product is extruded and extended by the crushing rollers 241 and becomes a larger, more uniform, fine pre-finished product with higher density. Afterward, the large-particle fine pre-finished product enters the extrusion chamber 120 and is extruded from the extrusion hole 111 under the pressure of the planetary gear 140, forming extruded granules with smaller particle size, higher density, and more uniform and compact size.

[0064] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this application.

[0065] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of this application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this application should be determined by the appended claims.
