[0002] Ordered heating cigarettes are one of the main technical routes for new tobacco products. The processing technology involves making the smoking matrix into a continuous sheet, cutting it into a certain width, rerolling it, and vacuum sealing it to prevent moisture changes. Commonly used smoking matrix processing technologies include new thick pulp sheet, papermaking thick pulp composite sheet, and dry papermaking sheet. When producing ordered heating cigarettes, the process involves unrolling, flattening, cutting, flavoring, bundling, shaping, cigarette cutting, and filter rod overlapping.

Detailed Implementation

[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, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the invention.

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

[0037] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

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

[0039] like Figures 1 to 3 As shown, this embodiment of the invention provides a heating cigarette smoke-generating matrix processing and forming device, including: a processing channel 501, a transverse extrusion device 502 and a vertical extrusion device 503.

[0040] The horizontal 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 disposed 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 5024.

[0042] Specifically, such as Figure 3 As shown, the transverse extrusion device 502 and the vertical extrusion device 503 are arranged sequentially along the conveying direction of the smoking matrix. 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 distance 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 in order 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 towards the sheet 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 a second extrusion on the sheet, thereby processing the sheet into a circular or elliptical shape.

[0045] This invention positions the transverse extrusion device 502 on the left and right sides of the processing channel 501, and the vertical extrusion device 503 on the upper and lower sides of the processing channel 501. The left transverse forming roller 5021 and the right transverse forming roller 5022 are respectively positioned 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. During operation, when the sheet is conveyed to the transverse extrusion device 502, the left transverse motor 5023 and the right transverse motor 5024 operate simultaneously, driving the left transverse forming roller 5021 and the right transverse forming roller 5022 to move towards the sheet and extrude it. Then, the sheet is conveyed through the processing channel 501 to the vertical extrusion device 503, where it performs a secondary extrusion, shaping the sheet into a circular or elliptical shape. This compact compression effectively improves the rolling quality of the smoke-generating matrix.

[0046] Furthermore, a bell mouth 700 is provided downstream of the vertical extrusion device 503. Thin sheets processed into circular or elliptical shapes are conveyed from the bell mouth 700 to the next process. After being wrapped with cigarette paper / forming paper, they move forward under the extrusion and traction of the cloth bag to carry out subsequent processing such as cutting, transfer, and attaching filter rods to form cigarettes.

[0047] In one embodiment of the heated cigarette smoke-generating matrix processing and molding apparatus of the present invention, the processing channel 501 is disposed between the transverse extrusion device 502 and the vertical extrusion device 503, and the cross-section of the processing channel 501 is U-shaped, which is beneficial to maintaining the shape of the sheet after it is bundled, and is also beneficial to conveying and re-extruding and molding.

[0048] In one embodiment of the heated cigarette smoke-generating matrix processing and molding apparatus of the present invention, such as 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 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 sets the upper longitudinal forming roller 5031 and the lower longitudinal forming roller 5032 outside the second end of the processing channel 501 and on the upper and lower sides of the processing channel 501, respectively. 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, which effectively ensures the compactness of the sheet.

[0050] Furthermore, the distance 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 to control the thickness of the sheet after extrusion, thereby controlling the compactness of the sheet filament bundle. When the equipment is started, the sheet filament bundle can be pressed compactly, with a diameter lower than the diameter of the cigarette, to facilitate passing through the cigarette gun. After the normal operating speed is reached, the gap can be adjusted appropriately to ensure that the cigarette is fully filled.

[0051] In one embodiment of the heated cigarette smoke-generating matrix processing and molding apparatus of the present invention, such as Figure 1 and Figure 2 As shown, the lengths of the two ends of the left transverse forming roller 5021, the right transverse forming roller 5022, the upper longitudinal forming roller 5031, and the lower longitudinal forming roller 5032 gradually decrease towards their center.

[0052] Specifically, after the sheet undergoes its first extrusion forming by the left transverse forming roller 5021 and the right transverse forming roller 5022, the longest side of the sheet should be no less than 5mm. After the left transverse forming roller 5021 and the right transverse forming roller 5022 are fully closed, the maximum transverse spacing between the holes between the left transverse forming roller 5021 and the right transverse forming roller 5022 should be ≤ the diameter of the cigarette, preferably less than the diameter of the cigarette (1.0-2.0) mm, which is more conducive to the pre-forming of the sheet. The closed holes can be circular or elliptical, preferably circular, which is more conducive to the pre-forming of the sheet into a circular shape.

[0053] Furthermore, during the production process, it was found that, under the same conditions of raw materials, materials, and cigarette quality indicators, different operators setting different sheet cutting spacing, manual guidance of sheet forming, and sheet bundle tension significantly affected the draw resistance of heated cigarettes during the bundling process. Draw resistance directly impacts the smoking experience of heated cigarettes. Since the raw materials used in ordered heated cigarettes consist of a continuous application of a large amount of atomizing agents and flavoring substances across a certain width, controlling and adjusting the draw resistance to achieve a better smoking experience, given the fixed structural parameters (length and circumference of each segment) and material structural parameters (circumference and structure of the filter rod, etc.), has become a challenge for the industry.

[0054] In this invention, when it is necessary to increase the draw resistance, the operator rotates the sheet filaments at a certain angle and passes them through the transverse extrusion device 502, and then passes the rotated sheet filaments through the vertical extrusion device 503. The beneficial effects of this method are: first, rotation can increase the path of air passage; second, the sheet filaments at a certain angle have a blocking effect on air; third, the amount of sheet filament filling can be increased slightly, thereby increasing the draw resistance; the tobacco filaments are held in place by the force of the transverse extrusion device 502 and the vertical extrusion device 503, so that the filaments always maintain a certain rotation angle.

[0055] When it is necessary to reduce suction resistance, the sheet can be passed straight through the transverse extrusion device 502 and the vertical extrusion device 503. The beneficial effects of this method are: 1. The straight state of the sheet can achieve the shortest air passage path; 2. It can reduce the obstruction effect of the sheet filament bundle on the air; 3. It slightly reduces the filling amount of the sheet filament bundle, thereby reducing suction resistance.

[0056] Furthermore, if further adjustment of the suction resistance is required, a differential speed setting can be made between the transverse extrusion device 502 and the vertical extrusion device 503. That is, taking advantage of the certain elongation of the sheet, the rotation speed of the transverse extrusion device 502 is slightly greater than that of the vertical extrusion device 503, which slightly stretches the sheet and further reduces the sheet filling amount by about (2-3)%, thereby further reducing the suction resistance. The ratio of the rotation speed of the transverse extrusion device 502 to that of the vertical extrusion device 503 is not greater than 1:1.05.

[0057] Both the rotational speed of the horizontal extrusion device 502 and the gap of the vertical extrusion device 503 can be adjusted to control the compactness of the thin sheet filament bundle. When the equipment is started, the thin sheet filament bundle can be pressed compactly, with a diameter lower than the diameter of the cigarette, so that it can pass through the cigarette gun. After the normal speed is reached, the gap can be adjusted appropriately to ensure that the cigarette is fully filled.

[0058] According to a second aspect of the present invention, a heating cigarette smoke-generating matrix processing system is provided, such as... Figures 3 to 6 As shown, the heated cigarette smoke-generating matrix processing and forming apparatus includes the aforementioned apparatus. The heated cigarette smoke-generating matrix processing system further includes, in sequence, a reel unwinding device 100, a conveying device 200, a sheet pre-forming device 300, and a flavoring device 400. The forming 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 made of a thin sheet 600, and the center of the reel unwinding device 100 has a reel roller 101 so that the thin sheet 600 can be wound on the reel roller 101, and the thin sheet 600 is conveyed to the conveying device 200 by the rotation of the reel roller 101.

[0060] The reel roller 101 is equipped 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 speed of the sheet 600 is consistent with the subsequent process as the diameter of the reel unwinding device 100 decreases.

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

[0062] The sheet preforming device 300 includes an upper pressure plate 301 and a lower pressure plate 302. The side walls of the upper pressure plate 301 and the lower pressure plate 302 are rotatably connected. A first pre-pressing component and a second pre-pressing component are correspondingly provided on the lower pressure plate 302 and the upper pressure plate 301, so that the sheet 600 forms a preset structure after being subjected to the action of the first and second pre-pressing components. Specifically, the side walls of the upper pressure plate 301 and the lower pressure plate 302 are connected by hinges, allowing the upper pressure plate 301 and the lower pressure plate 302 to open or close. Before production, the upper pressure plate 301 is opened. After the sheet 600 is conveyed to the sheet preforming device 300, the upper pressure plate 301 is closed and locked.

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

[0064] During operation, the sheet 600 is conveyed to the sheet preforming device 300 via the conveying device 200. The sheet 600 is pre-processed and shaped by the first pre-pressing component on the lower pressure plate 302 and the second pre-pressing component on the upper pressure 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 shaped by the forming device 500.

[0065] This invention rotatably connects the sidewalls of the upper pressure plate 301 and the lower pressure plate 302. The lower pressure plate 302 and the upper pressure plate 301 are respectively provided with a first pre-pressing component and a second pre-pressing component, so that the sheet 600 forms a preset structure after being subjected to the action of the first and second pre-pressing components. A sheet bundle pre-forming device 500 is located at the first end of the sheet pre-forming device 300, and a fragrance-adding device 400 is located at the second end of the sheet pre-forming device 300. During operation, the sheet 600 is conveyed to the sheet pre-forming device 300 via the conveying device 200. The first pre-pressing component on the lower pressure plate 302 and the second pre-pressing component on the upper pressure plate 301 pre-process and shape the sheet 600, processing it into the preset structure. Then, the fragrance-adding device 400 adds fragrance to the sheet 600, and the forming device 500 bundles and shapes the fragranced sheet 600. This invention has a simple structure, can effectively reduce the problem of yellow smoke, achieves automatic gathering, and reduces the operational difficulties for operators.

[0066] Furthermore, extrusion rollers are provided on both sides of the second end of the sheet preforming device 300. The roller surfaces are covered with rubber or other elastic materials, and the rollers are connected to a spring mechanism to fix the two sides of the formed sheet 600. Alternatively, a pair of electric rollers can be provided on each side of the second end of the sheet preforming device 300. The electric roller surfaces are covered with rubber or other elastic materials, and the electric rollers use adjustable bearings, rotating arms, and other mechanisms to adjust the pressure or spacing between the electric rollers, providing forward conveying force to the sheet 600 while maintaining its formed state.

[0067] In one embodiment of the heated cigarette smoke-generating matrix processing system of the present invention, such as Figure 4 and Figure 5 As shown, the first pre-compression component includes a first protrusion 3021 and a second protrusion 3022. The first protrusion 3021 and the second protrusion 3022 extend along the length direction of the lower pressure plate 302 and are respectively located on both sides of the center line of the lower pressure plate 302. A pressure groove 3023 is formed between the first protrusion 3021 and the second protrusion 3022.

[0068] The second pre-compression component includes a third protrusion 3011, a first groove 3012, and a second groove 3013. The third protrusion 3011 extends along the length of the upper pressure plate 301 and is located at the center line of the upper pressure plate 301. The third protrusion 3011 is opposite to the pressure groove 3023. The first groove 3012 and the second groove 3013 are located on both sides of the third protrusion 3011. The first groove 3012 and the second groove 3013 are opposite to the first protrusion 3021 and the second protrusion 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 protrusion 3021 and the second protrusion 3022 are higher than the end face of the lower pressure plate 302, the third protrusion 3011 is higher than the end face of the upper pressure plate 301, and the first groove 3012 and the second groove 3013 are lower than the end face of the upper pressure plate 301.

[0071] When the upper pressure plate 301 and the lower pressure plate 302 are engaged, the third protrusion 3011 is inserted into the groove 3023 between the first protrusion 3021 and the second protrusion 3022. The first protrusion 3021 and the second protrusion 3022 are respectively inserted into the first groove 3012 and the second groove 3013. Through the interaction of the first protrusion 3021, the second protrusion 3022, the groove 3023, the third protrusion 3011, the first groove 3012 and the second groove 3013, the sheet 600 located between the upper pressure plate 301 and the lower pressure plate 302 is squeezed into an M-shaped structure. This allows the fragrance device 400 to spray fragrance into the middle of the M-shaped sheet 600, 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 protrusion 3021 and the height of the second protrusion 3022 can be equal or unequal, and no restriction is imposed here.

[0073] When the height of the first protrusion 3021 and the height of the second protrusion 3022 are equal, that is, after the sheet 600 is extruded, the two ends of the M-shaped sheet 600 are at the same height.

[0074] When the height of the first protrusion 3021 and the height of the second protrusion 3022 are not equal, that is, after the sheet 600 is extruded, the heights of the two ends of the M-shaped sheet 600 are not the same, and there is a positional difference.

[0075] In one embodiment of the heated cigarette smoke-generating matrix processing system of the present invention, such as Figure 4 and Figure 5As shown, the first end of the upper pressure plate 301 and the first end of the lower pressure plate 302 are positioned close to the fragrance applicator 400. The heights of the first protrusion 3021, the second protrusion 3022, and the third protrusion 3011 are gradually reduced from the first end of the lower pressure plate 302 and the first end of the upper pressure plate 301, toward the second end of the lower pressure plate 302 and the second end of the upper pressure plate 301, respectively.

[0076] Specifically, the depth of the pressure groove 3023, the depth of the first groove 3012, and the depth of the second groove 3013 are gradually reduced from the first end of the lower pressure plate 302 and the first end of the upper pressure plate 301, and towards the second end of the lower pressure plate 302 and the second end of the upper pressure plate 301, respectively.

[0077] This invention addresses the issue of sheet damage by gradually decreasing the heights of the first protrusion 3021, the second protrusion 3022, and the third protrusion 3011 from the first end of the lower pressure plate 302 and the first end of the upper pressure plate 301, and towards the second end of the lower pressure plate 302 and the second end of the upper pressure plate 301, respectively. This design allows the sheet 600 to have a buffer space when conveyed by the conveying device 200 into the sheet preforming device 300, thus enabling it to be gradually compressed into an M-shaped structure. This effectively reduces the risk of sheet damage and lowers costs.

[0078] In one embodiment of the heated cigarette smoke-generating matrix processing system of the present invention, such as Figure 4 and Figure 5 As shown, the first pre-compression component also includes a third groove 3024 and a fourth groove 3025. The third groove 3024 is disposed on the outside of the first protrusion 3021, and the fourth groove 3025 is disposed on the outside of the second protrusion 3022.

[0079] The second pre-compression component also includes a fourth protrusion 3014 and a fifth protrusion 3015. The fourth protrusion 3014 is disposed on the outer surface of the first groove 3012, and the fifth protrusion 3015 is disposed on the outer surface of the second groove 3013. The fourth protrusion 3014 and the fifth protrusion 3015 are respectively disposed opposite to the third groove 3024 and the fourth groove 3025.

[0080] The present invention provides a third groove 3024 disposed on the outside of the first protrusion 3021, a fourth groove 3025 disposed on the outside of the second protrusion 3022, a fourth protrusion 3014 disposed on the outer surface of the first groove 3012, and a fifth protrusion 3015 disposed on the outside of the second groove 3013. The fourth protrusion 3014 and the fifth protrusion 3015 are respectively disposed opposite to the third groove 3024 and the fourth groove 3025. As a result, after the sheet 600 is processed by the first pre-pressing component and the second pre-pressing component, the entire sheet 600 can form a complete M-shaped structure.

[0081] In one embodiment of the heated cigarette smoke-generating matrix processing system of the present invention, the width of the third groove 3024 and the width of the fourth groove 3025 remain unchanged from the first end of the upper pressure plate 301 toward the second end of the upper pressure plate 301, and then gradually increase.

[0082] The width of the fourth protrusion 3014 and the width of the fifth protrusion 3015 remain constant from the first end of the lower pressure plate 302 toward the second end of the upper pressure plate 301, and then gradually increase.

[0083] The present invention protects the sheet 600 from the compression process by keeping the widths of the third groove 3024 and the fourth groove 3025 constant from the first end of the upper pressure plate 301 toward the second end of the upper pressure plate 301 and then gradually increasing them, and keeping the widths of the fourth protrusion 3014 and the fifth protrusion 3015 constant from the first end of the lower pressure plate 302 toward the second end of the upper pressure plate 301.

[0084] Furthermore, the heights of the fourth protrusion 3014 and the fifth protrusion 3015 are gradually reduced from the first end of the upper pressure plate 301 toward the second end of the upper pressure plate 301.

[0085] The heights of the third groove 3024 and the fourth groove 3025 are gradually reduced from the first end of the lower pressure plate 302 toward the second end of the lower pressure plate 302.

[0086] The present invention provides a buffering effect for the extrusion molding process of the sheet 600 by setting the height of the fourth protrusion 3014 and the height of the fifth protrusion 3015 to gradually decrease from the first end of the upper pressure plate 301 toward the second end of the upper pressure plate 301, and setting the height of the third groove 3024 and the height of the fourth groove 3025 to gradually decrease from the first end of the lower pressure plate 302 toward the second end of the lower pressure plate 302.

[0087] In one embodiment of the heated cigarette smoke-generating matrix processing system of the present invention, the outer side wall of the third groove 3024 and the outer side wall of the fourth groove 3025 are arranged perpendicularly to the end face of the lower pressure plate 302, and 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 30 degrees to 90 degrees.

[0088] The outer side wall of the fourth protrusion 3014 and the outer side wall of the fifth protrusion 3015 are perpendicular to the end face of the upper pressure plate 301, and the angle between the inner side wall of the fourth protrusion 3014 and the inner side wall of the fifth protrusion 3015 and the end face of the upper pressure plate 301 is 30 degrees to 90 degrees.

[0089] It should be noted that, as Figure 6 As shown, 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 α. 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 90 degrees, the inner wall of the third groove 3024 and the inner wall of the fourth groove 3025 is perpendicular to the end face of the lower pressure plate 302, and thus the side wall of the processed sheet 600 is perpendicular.

[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 in an inclined state, and the side wall of the processed sheet 600 is inclined.

[0091] In one embodiment of the heated cigarette smoke-generating matrix processing system of the present invention, the sheet preforming device 300 further includes a handle 303, a locking plate and a snap-fit ​​block. The handle 303 is disposed on the upper pressure plate 301. The first end of the locking plate is rotatably connected to the upper pressure plate 301. The locking plate has an opening. The snap-fit ​​block is movably disposed on the lower pressure plate 302 and passes through the opening.

[0092] This invention involves placing a handle 303 on the upper pressure plate 301, which can open or close the upper pressure plate 301. The first end of a locking plate is rotatably connected to the upper pressure plate 301. The locking plate has an opening, and a snap-fit ​​block is movably disposed on the lower pressure plate 302. The snap-fit ​​block passes through the opening, and by rotating the snap-fit ​​block, the opening can be snapped into place, thereby locking the upper pressure plate 301 and the lower pressure plate 302, so that the upper pressure plate 301 and the lower pressure plate 302 can compress the sheet 600 into a preset structure.

[0093] In one embodiment of the heated cigarette smoke-generating matrix processing system of the present invention, the conveying device 200 includes a plurality of conveying rollers 201, two limiting rollers 202, two slitting rollers 203 and two guide rollers 204 arranged in a single configuration. The plurality of conveying rollers 201 are arranged at intervals to convey the sheet 600 to the limiting rollers 202. The two limiting rollers 202, the two slitting rollers 203 and the two guide rollers 204 are respectively arranged on both sides of the sheet 600.

[0094] Specifically, after the reel unwinding device 100 unwinds the coil, it is unfolded by the rotation of the reel roller 101 and then stretched and flattened by multiple conveyor rollers 201, which are driven by a servo motor. After being stretched and flattened, the sheet 600 is flattened and limited by two limiting rollers 202 to prevent the sheet 600 from swaying and causing problems such as the sheet 600 being cut into wires.

[0095] Next, after being limited by the limiting roller 202, the sheet 600 enters the slitting roller 203 for pressing and cutting, which is conducive to the gathering. The slitting roller 203 is a mature technology in the industry and is not restricted here. After pressing and cutting, the sheet 600 forms a continuous sheet 600 with indentations, and the sheet 600 is in a complete state.

[0096] Next, the sheet 600 cut by the slitting roller 203 is guided by two guide rollers 204; the guide rollers 204 are driven by a servo motor, and the spacing between the guide rollers 204 is adjustable.

[0097] The sheet 600 is guided out of the pre-forming device 300 by the guide roller 204; the sheet 600 is in a relaxed state between the guide roller 204 and the pre-forming device 300, which is conducive to the pre-forming device 300 extruding the sheet 600.

[0098] In addition, during the production process, when it is necessary to increase the suction resistance, the gap between the two slitting rollers 203 is reduced to completely slit the sheet into continuous filaments. The gap between the two slitting rollers 203 is generally less than 50 filaments. When it is necessary to reduce the suction resistance, the gap between the two slitting rollers 203 is increased to roll the sheet into a continuous sheet base with certain indentations. The gap between the two slitting rollers 203 is generally greater than 50 filaments.

[0099] While specific embodiments of the invention have been described in detail by way of examples, those skilled in the art should understand that the examples are for illustrative purposes only and not intended to limit the scope of the invention. Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of the invention. The scope of the invention is defined by the appended claims.
