Description

Technical Field

[0001] This patent relates to the field of tobacco production technology, specifically to a cutting device for filter materials in aerosol-generated products. Background Technology

[0002] Aerosols contain over 5,000 compounds, of which approximately 2,740 are produced by tobacco combustion. Some components of tobacco smoke, such as benzene, aldehydes, volatile nitrosamines, and benzo[a]pyrene, have been proven to be harmful and potentially carcinogenic. Therefore, tobacco filters, as functional components that can effectively filter out some harmful substances, have received widespread attention and application. Currently, the main types of conventional tobacco filter materials on the international market are paper filters, cellulose acetate filters, and polypropylene fiber filters. Paper filters have lower retention efficiency, are prone to softening due to moisture, easily absorb aroma components from tobacco smoke, and can impart a papery smell to the smoke, resulting in a low market penetration.

[0003] Fiber acetate is widely used in the tobacco industry for its filters due to its good flavor absorption, firm texture, high tar retention efficiency, and attractive appearance. Polypropylene fiber filters have a significant cost advantage over cellulose acetate filters, but their tar retention rate is lower than that of cellulose acetate filters at the same pressure drop. Furthermore, they have poor heat resistance and are prone to thermal collapse. Therefore, polypropylene filters are mostly used in lower-end cigarette products. Besides the commonly used filters mentioned above, new cigarette filter materials internationally include Philtron Nacroco and starch-based filter materials, but these have not been widely adopted due to their high cost and altered flavor profile, respectively.

[0004] With the increasing awareness of health and environmental protection among consumers and the EU's ban on plastics, major tobacco companies have shifted their focus from cellulose acetate tow, polypropylene tow, and traditional paper materials to paper rods and non-woven filter rods with higher adsorption performance and better biodegradability. Using non-woven fabric as the molding material for filter rods is a new filter rod production process that has emerged in recent years. The materials are widely available and can be used for the development of various functional new filter rods.

[0005] Paper rods and non-woven fabrics are made from sheet materials. The processing and forming method of these filter rods is quite different from that of towed materials. The rolled sheet is supplied to the filter tip manufacturing device in the form of a continuous web. The filter tip manufacturing device uses the continuous web of rolled paper supplied to the filter tip manufacturing device to form the filter rod. Then the filter rod is cut into separate filter tips of predetermined lengths. The appearance, suction resistance, hardness and other physical properties of these filter rods are highly dependent on the width of the sheet.

[0006] Therefore, there is a need for a cutting device that can adapt to different widths of filter media, improve the adaptability of sheet materials to the machine, and be able to cut according to the appearance of the filter rod and physical indicators such as suction resistance and hardness, while being easy to operate and having a good cutting effect. Utility Model Content

[0007] To overcome the technical problems in existing technologies, such as poor adaptability of filter media to the machine, inability to cut according to the appearance and physical properties of the filter rod (such as suction resistance and hardness), inability to adjust the required cutting width of the filter media in real time, uneven cutting of the filter media, and overly complicated operation of adjusting the cutting width of the filter media, this patent provides the following technical solution:

[0008] First aspect: A cutting device for filter media in aerosol generation products is provided. The cutting device includes a support assembly, a cutting tool assembly, and an adjustment assembly. The support assembly and the cutting tool assembly are fixed relative to each other. When the cutting device is not in operation, the filter media is divided by the cutting tool assembly after the width is adjusted by the adjustment assembly; or when the cutting device is in operation, the filter media is divided by the cutting tool assembly after the width is changed by the adjustment assembly.

[0009] Furthermore, the adjustment assembly includes retractable transition rods, which are used to straighten the curled filter media before feeding it into the cutter assembly. The number of transition rods is 2 to 4, 4 to 6, or 6 to 8.

[0010] Furthermore, the support assembly includes a tool receiving cavity, an extension rod, and a fixing member, wherein the tool receiving cavity is positioned opposite to the tool assembly via the extension rod and the fixing member.

[0011] Furthermore, the tool assembly includes a cutting blade, a rotating shaft, a motor, and a stationary block. The cutting blade is driven to rotate by the rotating shaft under the drive of the motor.

[0012] Furthermore, the filter material is a continuous sheet material, which is selected from one of the following: non-woven fabric, corrugated paper, cotton pulp paper, cork paper, engineering plastics, and metal.

[0013] Furthermore, the width of the sheet material is selected from 183–193 mm, 193–203 mm, or 203–213 mm.

[0014] Furthermore, the absorption resistance of the sheet material is selected from 261–274 mmH2O, 274–287 mmH2O, and 287–300 mmH2O; the hardness of the sheet material is selected from 81–86%, 86–91%, or 91–96%.

[0015] Furthermore, the cutting device also includes a storage unit for collecting the filter material after the cutting process by the blade assembly.

[0016] Furthermore, the cutting device also includes a winding assembly disposed at the beginning and / or end of the cutting device, the winding assembly being used to provide coiled filter media and / or collect excess filter media after cutting.

[0017] Furthermore, the cutting device also includes a control component for controlling the start or stop of the tool assembly, winding assembly, and adjustment assembly.

[0018] This patent has the following beneficial effects:

[0019] 1. This patent relates to the field of tobacco production technology, specifically to a cutting device for filter material in aerosol-generated products, including a support assembly, a cutting tool assembly, an adjusting assembly, a winding assembly, a control assembly, and a storage component, wherein the support assembly and the cutting tool assembly are relatively fixed, and the width of the filter material is adjusted in real time by adjusting the support assembly, the cutting tool assembly, and the adjusting assembly.

[0020] 2. The adjustment component in this patent includes a telescopic transition rod. The length of the transition rod can be adjusted in real time according to the appearance, suction resistance and hardness of the filter rod, thereby changing the relative position of the support component and the cutter component, and thus changing the position of the filter material entering the cutter component. This can adapt to the machine adaptability of filter rods of different specifications.

[0021] 3. The support assembly and the cutter assembly in this patent also have telescopic adjustable parts. Therefore, the width of the filter material can be changed by adjusting the telescopic parts of the support assembly and the cutter assembly. Online cutting of sheets of different widths can be achieved according to different filter rod specifications, which can reduce the dependence of paper machine equipment on the width of the filter material.

[0022] 4. Compared with adjusting the position of the cutter and support unit on the transition rod, the cutting device in this patent has the advantages of being safer, more reliable and more precise in controlling the engagement of the cutting device and the support unit. At the same time, the online cutting device can achieve neat cuts when cutting sheets of different materials.

[0023] In the following embodiments, "aerosol generating article" can refer to any smokeable article or any article that provides a smoking experience, regardless of whether it is based on tobacco, tobacco derivatives, expanded tobacco, reconstituted tobacco, or tobacco substitutes. For example, aerosol generating articles may include aerosol generating articles such as cigarettes, cigars, and cigarillos. As another example, aerosol generating articles may include combustible aerosol generating articles and aerosol generating articles.

[0024] Preferably, the aerosol forming matrix is ​​a solid aerosol forming matrix. The aerosol forming matrix may simultaneously comprise solid and liquid components. Preferably, the aerosol forming matrix includes nicotine. In some preferred embodiments, the aerosol forming matrix includes tobacco.

[0025] Alternatively, the solid aerosol forming matrix may contain tobacco volatile aromatic compounds or non-tobacco volatile aromatic compounds released when the solid aerosol forming matrix is ​​heated. The solid aerosol forming matrix may also contain one or more capsules, which include, for example, additional tobacco volatile aromatic compounds or non-tobacco volatile aromatic compounds, and such capsules may melt during heating of the solid aerosol forming matrix.

[0026] Alternatively, the solid aerosol forming matrix can be disposed on or embedded in a heat-stabilized carrier. The carrier can be in the form of powder, granules, pellets, fragments, strips, bars, or sheets. The solid aerosol forming matrix can be arranged on the surface of the carrier, for example, in the form of sheets, foams, gels, or slurries. The solid aerosol forming matrix can be placed on the entire surface of the carrier, or alternatively, it can be patterned to provide uneven fragrance delivery during use.

[0027] The aerosol forming matrix can be in the form of a plug, which includes aerosol forming material defined by paper or other packaging material. In the case where the aerosol forming matrix is ​​in the form of a plug, the entire plug comprising any packaging paper is considered to be the aerosol forming matrix.

[0028] Preferably, the aerosol forming matrix includes a stopper, which comprises an aggregate of homogeneous tobacco material or other aerosol forming material surrounded by packaging material.

[0029] In this patent, "aerosol forming agent" is used to describe any suitable known compound or mixture of compounds that promotes aerosol formation in use and is substantially resistant to thermal degradation at the operating temperature of the aerosol-generated article.

[0030] Suitable aerosol forming agents are known in the art and include, but are not limited to: polyols, such as propylene glycol, triethylene glycol, 1,3-butanediol, and glycerol; esters of polyols, such as glycerol monoacetate, glycerol diacetate, or glycerol triacetate; and aliphatic esters of mono-, di-, or polycarboxylic acids, such as dimethyl dodecanoate and dimethyl tetradecanoate. Preferred aerosol forming agents are polyols or mixtures thereof, such as propylene glycol, triethylene glycol, 1,3-butanediol, and most preferably glycerol.

[0031] The aerosol forming matrix may include a single aerosol forming agent. Alternatively, the aerosol forming matrix may include a combination of two or more aerosol forming agents.

[0032] Preferably, the aerosol forming matrix has an aerosol forming agent content of more than 5% by dry weight. More preferably, the aerosol forming matrix may have an aerosol forming agent content between about 5% and about 30% by dry weight. In one embodiment, the aerosol forming matrix has an aerosol forming agent content of about 20% by dry weight.

[0033] Aerosol-formed products can have the shape of traditional cigarettes. Cigarette-like articles and their specifications are usually named according to the length of the cigarette, as described below. "Standard" typically refers to cigarettes in the range of 68mm to 75mm, for example, approximately 68mm to 72mm in length; "short" or "mini" refers to cigarettes shorter than 68mm; "extra-standard" typically refers to cigarettes in the range of 75mm to 91mm, for example, approximately 79mm to 88mm in length; "long" or "extra-long" typically refers to cigarettes in the range of 91mm to 105mm, for example, approximately 94mm to 101mm in length; and "extra-long" typically refers to cigarettes in the range of approximately 110mm to 121mm in length. Additionally, cigarette articles are named according to the outer circumference of the cigarette, as described below. The terms "standard" and "extra-fine" refer to cigarettes with a circumference of approximately 23mm to 25mm; "coarse" refers to cigarettes with a circumference of more than 25mm; "fine" refers to cigarettes with a circumference of approximately 22mm to 23mm; "long and thin" refers to cigarettes with a circumference of approximately 19mm to 22mm; "extra-fine" refers to cigarettes with a circumference of approximately 16mm to 19mm; and "micro-fine" refers to cigarettes with a circumference of less than 16mm. Therefore, extra-standard and extra-fine cigarettes have, for example, a length of approximately 83mm and a circumference of approximately 17mm. Standard and extra-standard cigarettes, with a length of 75mm to 91mm and a circumference of 23mm to 25mm, are popular with many customers. Cigarette products of various sizes can also be manufactured with filters of different lengths. Generally, short filters are used for cigarette products with both short length and short circumference. Typically, filter tip lengths range from 15mm, used with "short" and "standard" cigarettes, to 30mm, used with "extra long" and "extra thin" cigarettes. The tipping paper in the longitudinal direction of the cigarette with a filter tip is, for example, 3mm to 10mm longer than the filter tip.

[0034] Preferably, the aerosol forming article includes an aerosol forming matrix, a support element, an aerosol cooling element, and a mouthpiece. Preferably, the aerosol forming matrix, support element, aerosol cooling element, and mouthpiece are generally cylindrical and have substantially similar outer diameters. For example, they have an outer diameter of at least 5 mm. Preferably, they have an outer diameter between about 5 mm and about 12 mm, for example, between about 5 mm and about 10 mm, or between about 6 mm and about 8 mm. In a preferred embodiment, the outer diameter is 7.2 mm + / - 10%.

[0035] In the following embodiments, "aerosol generating material" can refer to a substance that generates smoke and / or aerosol or is used for smoking. For example, the aerosol generating material may include tobacco materials. For example, the aerosol generating material may include tobacco leaves, tobacco stems, or substances processed therefrom. As a more specific example, the aerosol generating material may include pulverized tobacco leaves, pulverized reconstituted tobacco, expanded pipe tobacco, expanded stems, and reconstituted tobacco. However, this disclosure is not limited thereto.

[0036] Preferably, the aerosol generating device is a smoking device that interacts with the aerosol generating matrix of the aerosol generating article to generate an aerosol that can be directly inhaled into the user's lungs through the user's mouth. The aerosol generating device may be a fixator for a smoking article.

[0037] The power source can be any suitable power source, such as a DC voltage source, like a battery. In one embodiment, the power source is a lithium-ion battery. Alternatively, the power source can be a nickel-metal hydride battery, a nickel-cadmium battery, or a lithium-based battery, such as a lithium cobalt, lithium iron phosphate, lithium titanate, or lithium polymer battery.

[0038] The control element can be a simple switch. Alternatively, the control element can be a circuit and may include one or more microprocessors or microcontrollers.

[0039] An aerosol generation system may include an aerosol generation device and one or more aerosol generation articles, wherein the aerosol generation device is configured with a corresponding number of heating chambers to contain the aerosol generation articles.

[0040] Tobacco sheets can be manufactured using existing manufacturing processes in the art, such as rolling, slurry processing, and papermaking, to include an aerosol-forming matrix for homogenizing tobacco sheets in aerosol-generating articles.

[0041] In this patent, sheet refers to a layered element having a width and length substantially greater than its thickness.

[0042] In this patent, the width of the sheet refers to the effective width of the sheet in the weft direction. 36 inches, 44 inches, and 56-60 inches are respectively called narrow width, medium width, and wide width. Fabrics larger than 60 inches are called extra wide widths, which are generally called wide width fabrics.

[0043] In this patent, the draw resistance of the sheet refers to the pressure that forces air through the entire cigarette to reach 17.5 ml / sec (20°C, 760 torr), a value expressed in mm or inches of water column.

[0044] In this patent, the aerosol forming matrix comprises a textured sheet of aggregated homogeneous tobacco material.

[0045] In this patent, textured sheet refers to a sheet that has been rolled, embossed, stamped, perforated, or otherwise deformed. The aerosol forming matrix may include an aggregate of textured sheets of homogeneous tobacco material, comprising a plurality of spaced notches, protrusions, perforations, or combinations thereof.

[0046] Preferably, the aerosol forming matrix comprises aggregated rolled sheets of homogeneous tobacco material. The use of textured sheets of homogeneous tobacco material can advantageously promote the aggregation of the homogeneous tobacco material sheets to form the aerosol forming matrix.

[0047] In this patent, "curled sheet" refers to a sheet having a plurality of substantially parallel ridges or folds. Preferably, when the aerosol-forming article has been assembled, the substantially parallel ridges or folds extend along or parallel to the longitudinal axis of the aerosol-forming article. This advantageously promotes the aggregation of the curled sheet of homogeneous tobacco material to form an aerosol-forming matrix.

[0048] However, it will be understood that the rolled sheet of homogeneous tobacco material used in the aerosol-generated article may alternatively or additionally have a plurality of substantially parallel ridges or wrinkles arranged at an acute or obtuse angle to the longitudinal axis of the aerosol-generated article when the aerosol-generated article has been assembled.

[0049] An electric motor is an electromagnetic device that converts or transmits electrical energy based on the law of electromagnetic induction. It is divided into electric motors (symbol M) and generators (symbol G).

[0050] Electric motors include DC motors, asynchronous motors, and synchronous motors. Synchronous motors can be further classified into permanent magnet synchronous motors, reluctance synchronous motors, and hysteresis synchronous motors; asynchronous motors can be classified into induction motors and AC commutator motors; DC motors can be classified according to their structure and working principle into brushless DC motors and brushed DC motors (permanent magnet DC motors and electromagnetic DC motors).

[0051] Permanent magnet DC motors also consist of stator poles, rotor, brushes, and housing. The stator poles use permanent magnets (permanent steel), made of materials such as ferrite, AlNiCo, and NdFeB. Based on their structural form, they can be divided into several types, including cylindrical and block-type. Most motors used in VCRs and players use cylindrical magnets, while motors used in power tools and automotive electrical appliances mostly use block-type magnets.

[0052] A brushless DC motor consists of a permanent magnet rotor, a multi-pole winding stator, and a position sensor. The position sensor commutates the current in the stator windings in a specific sequence according to changes in the rotor position. The operating voltage of the stator windings is provided by an electronic switching circuit controlled by the position sensor output.

[0053] An AC asynchronous motor is an electric motor that operates using alternating current (AC) voltage. AC asynchronous motors are divided into induction motors and AC commutator motors. Induction motors are further divided into single-phase asynchronous motors, AC / DC universal motors, and repulsion motors. The motor's speed (rotor speed) is less than the speed of the rotating magnetic field, hence the name asynchronous motor.

[0054] Synchronous motors, like induction motors, are commonly used AC motors. Their key characteristic is that, during steady-state operation, the rotor speed and the power grid frequency maintain a constant relationship. If the power grid frequency remains constant, the synchronous motor's speed in steady state is always constant and independent of the load. Synchronous motors are classified into synchronous generators and synchronous motors.

[0055] A power supply module is a power supply unit that can be directly mounted on a printed circuit board. Its key feature is that it can provide power to application-specific integrated circuits (ASICs), digital signal processors (DSPs), microprocessors, memory, field-programmable gate arrays (FPGAs), and other digital or analog loads. Generally, these modules are called point-of-use (POL) power supply systems or point-of-use power supply systems (PUPS).

[0056] Switching power supplies can be broadly classified into AC / DC and DC / DC converters. DC / DC converters are now modular. DC / DC conversion transforms a variable DC voltage into a fixed DC voltage, also known as DC chopping. AC / DC conversion converts alternating current (AC) to direct current (DC), and its power flow can be bidirectional. Power flowing from the power source to the load is called "rectification," while power flowing from the load back to the power source is called "active inversion." Due to the numerous advantages of modular structures, modular power supplies are widely used in switching equipment, access equipment, mobile communications, microwave communications, optical transmission, routers, and other communication fields, as well as in automotive electronics and aerospace.

[0084] To make the objectives, technical solutions, and advantages of this patent clearer, the embodiments of this patent will be described in further detail below with reference to the accompanying drawings.

[0085] Unless otherwise specified, the aerosol-generating products in this patent are specifically cigarette products.

[0086] Please refer to Figures 1-3 A cutting device for filter media in aerosol-generated products includes a support assembly 100, a cutter assembly 200, an adjustment assembly 300, a winding assembly 400, a storage component 500, and a control assembly (not shown). After the filter media enters the cutting device, it passes through the winding assembly 400, the adjustment assembly 300, the cutter assembly 200, the storage component 500, and the winding assembly 400 in sequence. The cutter assembly 200, the support assembly 100, and the storage component 500 are set at different heights along the vertical direction.

[0087] Specifically, the cutting device claimed in this patent is used in the production workshop of filter tip segments of aerosol-generated products, especially after the feeding system of the paper machine equipment that produces filter tip segments. The cutting device of this patent application adjusts the width in real time and cuts the target filter material according to the appearance, suction resistance and hardness of the target filter material.

[0088] Specifically, the support assembly 100 and the cutter assembly 200 are relatively fixed, with the support assembly 100 positioned above the cutter assembly 200 and the storage unit 500 positioned below the cutter assembly 200. The cut filter material falls into the storage unit 500 by gravity. The relatively fixed support assembly 100 and the cutter assembly 200 enable the cutting device to operate more stably during operation, and the structure of the support assembly 100 provides safety protection for the cutter assembly 200.

[0089] Specifically, the winding assembly 400 first collects the filter material entering the cutting device from the feeding system. The first winding roller 410 in the winding assembly 400 is located at the front end of the cutting device. The first winding roller 410 curls and collects the filter material and provides it to the adjusting assembly 300 from the other end.

[0090] Specifically, the adjustment assembly 300 includes a telescopic transition rod for straightening the curled filter media before feeding it into the cutter assembly 200.

[0091] Specifically, the telescopic transition rod is a telescopic hollow cylindrical rod made of metal strip. Its characteristic is that the metal strip is pre-shaped into an elastic coiled layer with memory function that is smaller than the outer diameter of the rod, thus having a self-tightening function, so that the coiled layer always has elastic potential energy to apply pressure to the telescopic rod.

[0092] Specifically, in this embodiment, there are three transition rods, which are arranged in an isosceles triangle structure along the axial direction. The first transition rod 310 and the third transition rod 330 are on the same horizontal plane as the cutting filter material, and the second transition rod 320 is located below the first transition rod 310 and the third transition rod 330, that is, in the axial direction, it forms an inverted triangle structure.

[0093] Specifically, the outer surface of the transition rod in contact with the filter media is sanded, which increases the relative friction between the outer surface of the transition rod and the filter media, making it easier to stabilize the filter media as it is transported to the cutter assembly 200.

[0094] Specifically, the filter material provided by the first winding roller 410 passes over the upper outer surface of the first transition rod 310, then over the lower outer surface of the second transition rod 320, and finally enters the cutter assembly 200 after passing through the upper outer surface of the third transition rod 330.

[0095] Specifically, the tool assembly 200 includes a blade 210, a rotating shaft 220, a motor 230, and a fixing block 240. The blade 210 is a circular blade, and its front end is fixed to the rotating shaft 220 through the fixing block 240. The rotating shaft 220 is a slender rod, and its end is connected to the motor 230 through a connector 250.

[0096] Specifically, the motor 230 is selected from permanent magnet synchronous motors, reluctance synchronous motors, hysteresis synchronous motors, induction motors, AC commutator motors, permanent magnet DC motors, electromagnetic DC motors, brushless DC motors, induction motors, AC commutator motors, permanent magnet synchronous motors, reluctance synchronous motors, hysteresis synchronous motors, three-phase asynchronous motors, single-phase asynchronous motors, and shaded-pole asynchronous motors, but this patent is not limited to these.

[0097] Specifically, the rotating shaft 220 is a telescopic rod that can adjust the width of the filter media in real time according to its appearance, suction resistance, and hardness.

[0098] Specifically, when the cutting device is in operation, the blade 210 is driven by the motor 230 to rotate through the shaft 220 to cut the filter material.

[0099] Specifically, the circular blade 210 can be made of low-carbon alloy steel (with less than 5% alloying elements), high-carbon alloy steel, austenitic cast steel, tool steel, ferritic stainless steel, martensitic stainless steel, tungsten carbide-based cemented carbide, titanium carbide (TiC(N))-based cemented carbide, TiCN-based cermet (HRA 91-94), polycrystalline cubic boron nitride PCBN (HV4000), polycrystalline diamond PCD (HV7500), but this patent is not limited to these.

[0100] Specifically, the support assembly 100 includes a blade receiving cavity 110, an extension rod 120, and a fixing member 130. The blade receiving cavity 110 is located at the front end of the support assembly 100 and is an arc-shaped recessed cavity. The blade receiving cavity 110 is used to receive the blade 210. It is easy to understand that the top of the blade 210 is placed in the blade receiving cavity 110 when the blade is stationary or in operation. This can prevent the high-speed rotating blade 210 from causing injury to the operator or causing filter material to splatter when cutting the filter material. At the same time, when the blade 210 is stationary, the blade receiving cavity 110 can protect the top of the blade 210 from the corrosion of contaminants.

[0101] Specifically, the cutter receiving cavity 110 is set opposite to the cutter assembly 200 via the extension rod 120 and the fixing member 130. The extension rod 120 is a telescopic rod that can adjust the width of the filter material in real time according to the appearance, suction resistance and hardness of the filter material.

[0102] Specifically, the rotational speed of the blade 210 and the type of the motor 230 can be varied, but this patent is not limited to these.

[0103] Specifically, the filter media is cut by the lower middle part of the blade 210.

[0104] Specifically, the width of the filter media cut by the cutting device is determined based on the requirements for the appearance, suction resistance, and hardness of the filter media.

[0105] Specifically, the filter material is a continuous sheet material, and the material of the filter material can be non-woven fabric, corrugated paper, cotton pulp paper, cork paper, engineering plastics, metal, etc. This patent is not limited to these.

[0106] Specifically, the width of the filter material is selected from 183-193mm, 193-203mm or 203-213mm, but this patent is not limited to this.

[0107] Specifically, the thickness of the filter material is selected from 0.03–0.13 mm, 0.13–0.23 mm, or 0.23–0.33 mm, and this patent is not limited to these.

[0108] Furthermore, the suction resistance of the filter material is selected from 261–274 mmwg, 274–287 mmwg, and 287–300 mmwg, and this patent is not limited thereto; the hardness is selected from 81–86%, 86–91%, or 91–96%, and this patent is not limited thereto.

[0109] Specifically, the storage unit 500 includes a box body, which is fixed below the cutter assembly 200. The filter material cut by the cutter assembly 200 falls into the storage unit 500 by gravity.

[0110] Specifically, the remaining filter material exits from the cutter assembly 200 and enters the second winding roller 420 where it is coiled and collected.

[0111] Specifically, the control component is used to control the start or stop of the tool assembly 200, the winding assembly 400, and the adjustment assembly 300. In particular, the control component contains an integrated circuit board, including a power module for controlling the start and stop of the cutting device, and a drive module for adjusting the rotational speed of the blade 210.

[0112] Specifically, the cutting device includes both working and non-working states.

[0113] Specifically, when the cutting device is in a non-working state, the cutter assembly 200, the winding assembly 400, and the adjusting assembly 300 are in a stationary state. At this time, the width of the cut filter material can be changed by adjusting the extension length of the adjusting assembly 300 and its position in the cutter assembly 200; or the width of the cut filter material can be changed by adjusting the extension length of the cutter assembly 200 and the support assembly 100.

[0114] Specifically, when the cutting device is in operation, the cutter assembly 200, the winding assembly 400, and the adjusting assembly 300 are all in operation. At this time, the width of the filter material being cut can be changed by adjusting the extension length of the adjusting assembly 300 and its position within the cutter assembly 200.

[0115] Specifically, taking non-woven filter media as an example, the physical parameters of non-woven filter rods with a width of 200mm before cutting and non-woven filter rods with a width of 192mm after cutting are shown in Table 1 and Table 2, respectively.

[0122] Specifically, the cutting device cuts the filter section of the aerosol-generated product based on its appearance, suction resistance, and hardness. The width of the filter media affects its suction resistance and hardness. In particular, the width of the non-woven filter media directly affects the appearance, suction resistance, and hardness of the formed non-woven filter rod. A wider width allows for higher filter rod filling, resulting in increased suction resistance and hardness; however, if the sheet width is too large, it cannot enter the smoking gun process. If the sheet width is too small, the filter rod will be underfilled, resulting in too many pores, low suction resistance, and insufficient hardness.
