DETAILED DESCRIPTION

[0035] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that the relative arrangement of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present invention unless otherwise specifically stated.

[0036] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses.

[0037] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.

[0038] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0039] like Figures 1 to 3 As shown, an embodiment of the present invention provides a device for processing and molding a smoking matrix of a heated cigarette, comprising: a processing channel 501 , a horizontal extrusion device 502 and a vertical extrusion device 503 .

[0040] The lateral extrusion device 502 is located on the left and right sides of the processing channel 501, and the vertical extrusion device 503 is located on the upper and lower sides of the processing channel 501. The processing channel 501 is used to transport thin sheets.

[0041] The transverse extrusion device 502 includes a left transverse forming roller 5021, a right transverse forming roller 5022, a left transverse motor 5023 and a right transverse motor 5024. The left transverse forming roller 5021 and the right transverse forming roller 5022 are respectively arranged outside the first end of the processing channel 501, the left transverse motor 5023 is connected to the left transverse forming roller 5021, and the right transverse forming roller 5022 is connected to the right transverse forming roller 5022.

[0042] Specifically, Figure 3 As shown, the transverse extrusion device 502 and the vertical extrusion device 503 are arranged in sequence along the conveying direction of the smoking substrate, that is, the sheet is first extruded by the transverse extrusion device 502 and then extruded by the vertical extrusion device 503.

[0043] In addition, the spacing between the left transverse forming roller 5021 and the right transverse forming roller 5022 can be adjusted by adjusting the parameters of the left transverse motor 5023 and the right transverse motor 5024 to control the thickness of the sheet after extrusion.

[0044] During operation, when the sheet is conveyed to the transverse extrusion device 502, the left transverse motor 5023 and the right transverse motor 5024 work simultaneously, driving the left transverse forming roller 5021 and the right transverse forming roller 5022 to move toward the sheet at the same time, and perform the first extrusion on the sheet; then, the sheet is conveyed to the vertical extrusion device 503 through the processing channel 501, so that the vertical extrusion device 503 performs the second extrusion on the sheet, and then the sheet is processed into a circular or elliptical shape.

[0045] The present invention arranges the lateral extrusion device 502 on the left and right sides of the processing channel 501, the vertical extrusion device 503 on the upper and lower sides of the processing channel 501, and arranges the left lateral forming roller 5021 and the right lateral forming roller 5022 outside the first end of the processing channel 501, respectively, and the left lateral motor 5023 is connected to the left lateral forming roller 5021, and the right lateral forming roller 5022 is connected to the right lateral forming roller 5022. When the sheet is conveyed to the lateral extrusion device 502, the left lateral motor 5023 and the right lateral motor 5024 work at the same time, driving the left lateral forming roller 5021 and the right lateral forming roller 5022 to move toward the sheet at the same time, and extruding the sheet; then, the sheet is conveyed to the vertical extrusion device 503 through the processing channel 501, so that the vertical extrusion device 503 performs secondary extrusion on the sheet, and then the sheet is processed into a circular or elliptical shape, so that the sheet is extruded tightly, and the rolling quality of the smoking matrix is ​​effectively improved.

[0046] Furthermore, a trumpet mouth 700 is also provided downstream of the vertical extrusion device 503. The thin slices processed into a circular or elliptical shape are transported from the trumpet mouth 700 to the next process. After being wrapped with cigarette paper / forming paper, they move forward under the squeezing and traction of the cloth bag to undergo subsequent processing such as cutting, transferring, and connecting filter rods to form cigarettes.

[0047] In one embodiment of the device for processing and molding the smoking matrix of heated cigarettes of the present invention, the processing channel 501 is arranged between the horizontal extrusion device 502 and the vertical extrusion device 503, and the cross-section of the processing channel 501 is a U-shaped structure, which is conducive to maintaining the shape of the sheet after contraction and is conducive to transportation and re-extrusion molding.

[0048] In one embodiment of the device for processing and forming a heated cigarette smoking substrate of the present invention, Figure 2 As shown, the vertical extrusion device 503 includes an upper longitudinal forming roller 5031, a lower longitudinal forming roller 5032, an upper longitudinal motor 5033 and a lower longitudinal motor 5034. The upper longitudinal forming roller 5031 and the lower longitudinal forming roller 5032 are respectively arranged outside the second end of the processing channel 501, and are located on the upper and lower sides of the processing channel 501. The upper transverse motor is connected to the upper transverse forming roller, and the lower transverse forming roller is connected to the lower transverse forming roller.

[0049] The present invention arranges the upper longitudinal forming roller 5031 and the lower longitudinal forming roller 5032 outside the second end of the processing channel 501 respectively, and is located on the upper and lower sides of the processing channel 501, the upper transverse motor is connected to the upper transverse forming roller, and the lower transverse forming roller is connected to the lower transverse forming roller. The upper and lower ends of the sheet are squeezed by the upper longitudinal forming roller 5031 and the lower longitudinal forming roller 5032, thereby effectively ensuring the tightness of the sheet being squeezed.

[0050] Furthermore, the spacing between the upper longitudinal forming roller 5031 and the lower longitudinal forming roller 5032 can be adjusted by adjusting the parameters of the upper longitudinal motor 5033 and the lower longitudinal motor 5034, so as to control the thickness of the thin film after extrusion, and then control the compactness of the thin film bundle. When the equipment is started, the thin film bundle can be pressed compactly and the diameter is lower than the diameter of the cigarette to facilitate passing through the cigarette gun. After the vehicle speed is normal, the gap is adjusted appropriately to ensure that the cigarette is fully filled.

[0051] In one embodiment of the device for processing and forming a heated cigarette smoking substrate of the present invention, Figure 1 and Figure 2 As shown, the lengths of both ends of the left lateral forming roller 5021, the right lateral forming roller 5022, the upper longitudinal forming roller 5031 and the lower longitudinal forming roller 5032 are gradually reduced toward their center positions.

[0052] Specifically, the longest side of the thin sheet after the first extrusion forming by the left transverse forming roller 5021 and the right transverse forming roller 5022 is not less than 5 mm. After the left transverse forming roller 5021 and the right transverse forming roller 5022 are completely closed, the maximum transverse spacing of the holes between the left transverse forming roller 5021 and the right transverse forming roller 5022 is ≤ the cigarette diameter, preferably less than the cigarette diameter (1.0-2.0) mm, which is more conducive to the preforming of the thin sheet. The closed holes can be circular or elliptical, preferably circular, which is more conducive to the preforming of the thin sheet into a circular shape.

[0053] In addition, it was found during the production process that under the same raw materials, materials and cigarette quality indicators, when the bundles were formed, different operators set different sheet pressing and cutting spacing, manually guided sheet forming states and sheet bundle tensioning states, which had a significant impact on the draw resistance of heated cigarettes, and the draw resistance directly affected the smoking experience of heated cigarettes. Since the raw materials used for orderly heated cigarettes are a large amount of atomizers and flavor substances applied continuously over a certain width, under the conditions determined by the heated cigarette structural parameters (length and circumference of each section) and material structural parameters (filter rod circumference, structure, etc.), how to control and adjust the draw resistance to achieve a better smoking experience has become a difficult problem in the industry.

[0054] In the present invention, when it is necessary to increase the resistance to draw, the operator rotates the thin sheet bundle by a certain angle and passes it through the horizontal extrusion device 502, and then passes the thin sheet rotated by a certain angle through the vertical extrusion device 503; the beneficial effects of this method are: first, the path for air to pass can be increased by rotation; second, the thin sheet bundle at a certain angle has a barrier effect on the air; third, the filling amount of the thin sheet wire can be increased by a small amount, thereby increasing the resistance to draw; the tobacco bundle is supported by the horizontal extrusion device 502 and the vertical extrusion device 503, so that the bundle always maintains a certain rotation angle.

[0055] When it is necessary to reduce the suction resistance, the thin sheet can be passed straight through the horizontal extrusion device 502 and the vertical extrusion device 503; the beneficial effects of this method are: first, the straight state of the thin sheet can achieve the shortest air passage path; second, it can reduce the air blocking effect of the thin sheet bundle; third, the filling amount of the thin sheet bundle is slightly reduced, thereby reducing the suction resistance.

[0056] Furthermore, if it is necessary to further adjust the suction resistance, a differential speed setting can be made between the transverse extrusion device 502 and the vertical extrusion device 503. That is, the rotation speed of the transverse extrusion device 502 can be slightly greater than that of the vertical extrusion device 503, taking advantage of the fact that the thin film has a certain elongation, and the thin film can be slightly stretched to further reduce the filling amount of the thin film by about (2-3)%, thereby further reducing the suction resistance; the rotation speed ratio of the transverse extrusion device 502 to the vertical extrusion device 503 is not greater than 1:1.05.

[0057] The rotation speed of the horizontal extrusion device 502 and the vertical extrusion device 503 can both adjust the gap, thereby controlling the compactness of the thin film bundle. When the equipment is started, the thin film bundle can be pressed compactly and the diameter is lower than the diameter of the cigarette, which is convenient for passing through the cigarette gun. After the vehicle speed reaches normal, the gap is adjusted appropriately to ensure that the cigarette is fully filled.

[0058] According to a second aspect of the present invention, a system for processing a heated cigarette smoking substrate is provided. Figures 3 to 6 As shown, the heated cigarette smokable matrix processing and molding device includes the above-mentioned heated cigarette smokable matrix processing and molding system, and the heated cigarette smokable matrix processing system also includes a reel unwinding device 100, a conveying device 200, a sheet preforming device 300 and a flavoring device 400 arranged in sequence. The molding device 500 is located downstream of the flavoring device 400. The reel unwinding device 100 is used to unwind the sheet 600.

[0059] Specifically, the reel unwinding device 100 is rolled up with the thin film 600, and has a reel roller 101 at the center so that the thin film 600 can be wound on the reel roller 101, and the thin film 600 is transported to the conveying device 200 by the rotation of the reel roller 101.

[0060] The reel roller 101 is provided with an expansion device, which can fix the reel unwinding device 100 on the reel roller 101; the reel roller 101 is driven by a servo motor to ensure that the unwinding linear speed of the sheet 600 is consistent with the subsequent process during the process of reducing the diameter of the reel unwinding device 100.

[0061] The conveying device 200 is used to convey the thin sheet 600 wound on the reel unwinding device 100, so that the thin sheet 600 is conveyed to the thin sheet preforming device 300. It should be noted that the conveying device 200 includes a pressing and cutting device for pressing and cutting the thin sheet 600 into continuous thin sheet wires of a certain width, or forming an indentation of a certain depth on the surface of the thin sheet 600 for easy bundling, and also includes a traction device for guiding the slit thin sheet wire bundle out of the pressing and cutting device and conveying the thin sheet 600 to the thin sheet preforming device 300. The specific structure is not limited here.

[0062] The sheet preforming device 300 includes an upper pressing plate 301 and a lower pressing plate 302. The side wall of the upper pressing plate 301 and the side wall of the lower pressing plate 302 are rotatably connected. The lower pressing plate 302 and the upper pressing plate 301 are correspondingly provided with a first pre-pressing assembly and a second pre-pressing assembly, so that the sheet 600 forms a preset structure after the first pre-pressing assembly and the second pre-pressing assembly. Specifically, the side wall of the upper pressing plate 301 and the side wall of the lower pressing plate 302 are connected by a hinge, so that the upper pressing plate 301 and the lower pressing plate 302 can be opened or buckled. Before production, the upper pressing plate 301 is opened, and after the sheet 600 is conveyed to the sheet preforming device 300, the upper pressing plate 301 is buckled and locked.

[0063] The sheet preforming device 300 is located at a first end of the sheet preforming device 300 , and the fragrance adding device 400 is located at a second end of the sheet preforming device 300 . The fragrance adding device 400 is used to add fragrance to the sheet 600 .

[0064] During operation, the sheet 600 is conveyed to the sheet preforming device 300 through the conveying device 200, and the sheet 600 is pre-processed and shaped by the first pre-pressing component on the lower pressing plate 302 and the second pre-pressing component on the upper pressing plate 301, so that the sheet 600 is processed into a preset structure; then the fragrance adding device 400 adds fragrance to the sheet 600, and the fragranced sheet 600 is bundled and formed by the forming device 500.

[0065] The present invention rotates and connects the side wall of the upper pressing plate 301 and the side wall of the lower pressing plate 302, and the lower pressing plate 302 and the upper pressing plate 301 are provided with a first pre-pressing assembly and a second pre-pressing assembly respectively, so that the thin slice 600 forms a preset structure after the action of the first pre-pressing assembly and the second pre-pressing assembly, and the slice bundle pre-forming device 500 is located at the first end of the thin slice pre-forming device 300, and the aroma device 400 is located at the second end of the thin slice pre-forming device 300. During operation, the thin slice 600 is transported to the thin slice pre-forming device 300 through the conveying device 200, and the thin slice 600 is pre-processed and shaped by the first pre-pressing assembly on the lower pressing plate 302 and the second pre-pressing assembly on the upper pressing plate 301, so that the thin slice 600 is processed into the preset structure; then the aroma device 400 adds aroma to the thin slice 600, and the aromatized thin slice 600 is subjected to a bunching and forming process by the forming device 500. The invention has a simple structure, can effectively reduce the yellow spot smoke problem, realizes automatic convergence, and reduces the operating difficulties of operators.

[0066] Furthermore, squeezing rollers are provided on both sides of the second end of the sheet preforming device 300, and the surfaces of the rollers are coated with rubber or other elastic materials. The rollers are connected to spring mechanisms to fix both sides of the formed sheet 600. A pair of electric rollers can also be provided on both sides of the second end of the sheet preforming device 300, and the surfaces of the electric rollers are coated with rubber or other elastic materials. The electric rollers use bearings with adjustable distances, rotating arms and other mechanisms to adjust the pressure or spacing between the electric rollers, so as to provide the sheet 600 with a forward conveying force while maintaining the sheet 600 in a formed state.

[0067] In one embodiment of the system for processing the smoking substrate of a heated cigarette of the present invention, Figure 4 and Figure 5 As shown, the first pre-pressing assembly includes a first protrusion 3021 and a second protrusion 3022, which are extended along the length direction of the lower pressing plate 302 and are respectively located on both sides of the center line of the lower pressing plate 302, and a pressing groove 3023 is formed between the first protrusion 3021 and the second protrusion 3022.

[0068] The second pre-pressing assembly includes a third convex body 3011, a first groove 3012 and a second groove 3013. The third convex body 3011 is extended along the length direction of the upper pressing plate 301 and is located at the center line of the upper pressing plate 301. The third convex body 3011 is arranged opposite to the pressing groove 3023. The first groove 3012 and the second groove 3013 are located on both sides of the third convex body 3011. The first groove 3012 and the second groove 3013 are arranged opposite to the first convex body 3021 and the second convex body 3022 respectively.

[0069] Furthermore, the first convex body 3021, the second convex body 3022 and the third convex body 3011 are all V-shaped structures.

[0070] Specifically, the first convex body 3021 and the second convex body 3022 are higher than the end surface of the lower pressing plate 302 , the third convex body 3011 is higher than the end surface of the upper pressing plate 301 , and the first groove 3012 and the second groove 3013 are lower than the end surface of the upper pressing plate 301 .

[0071] When the upper pressing plate 301 and the lower pressing plate 302 are buckled with each other, the third protrusion 3011 is inserted into the pressing groove 3023 between the first protrusion 3021 and the second protrusion 3022, and the first protrusion 3021 and the second protrusion 3022 are respectively inserted into the first groove 3012 and the second groove 3013, and then through the interaction of the first protrusion 3021, the second protrusion 3022, the pressing groove 3023, the third protrusion 3011, the first groove 3012 and the second groove 3013, the sheet 600 located between the upper pressing plate 301 and the lower pressing plate 302 is squeezed into an M-shaped structure, so that the fragrance adding device 400 can spray the fragrance into the middle of the sheet 600 of the M-shaped structure, so that the fragrance can be preserved in the sheet 600 for a longer time.

[0072] It should be noted that the height of the first convex body 3021 and the height of the second convex body 3022 may be equal or unequal, which is not limited here.

[0073] When the height of the first convex body 3021 is equal to the height of the second convex body 3022 , that is, after the sheet 600 is extruded, both ends of the sheet 600 of the M-shaped structure are at the same height.

[0074] When the height of the first convex body 3021 is not equal to the height of the second convex body 3022 , that is, after the sheet 600 is extruded, the heights of the two ends of the sheet 600 of the M-shaped structure are different, and there is a position difference.

[0075] In one embodiment of the system for processing the smoking substrate of a heated cigarette of the present invention, Figure 4 and Figure 5As shown, the first end of the upper pressing plate 301 and the first end of the lower pressing plate 302 are configured to be close to the fragrance adding device 400, and the height of the first protrusion 3021, the height of the second protrusion 3022 and the height of the third protrusion 3011 are gradually reduced from the first end of the lower pressing plate 302 and the first end of the upper pressing plate 301 toward the second end of the lower pressing plate 302 and the second end of the upper pressing plate 301, respectively.

When the angle between the inner side wall of the third groove 3024 and the inner side wall of the fourth groove 3025 and the end face of the lower pressure plate 302 is 90 degrees, at this time, the inner side wall of the third groove 3024 and the inner side wall of the fourth groove 3025 are vertical to the end face of the lower pressure plate 302, and thus the side wall of the processed thin film 600 is vertical.

[0090] When the angle between the inner wall of the third groove 3024 and the inner wall of the fourth groove 3025 and the end face of the lower pressure plate 302 is greater than 30 degrees and less than 90 degrees, the inner wall of the third groove 3024 and the inner wall of the fourth groove 3025 are inclined, and thus the side wall of the processed thin film 600 is inclined.
