Abstract

According to the sorting method for the aerosol generating matrix, the impurity removing stage, the quantitative feeding stage and the moisture content sorting stage are distinguished in the process, the three stages cooperatively operate under coordination of the control mechanism, and therefore the detection precision of the moisture content of the aerosol generating matrix and the accuracy of sorting according to the moisture content are improved. The magnetic scrap removing mechanism removes scrap iron, interference of heat conductivity of the scrap iron on the moisture content detector is avoided, after an aerosol generation matrix subjected to impurity removal enters the dynamic detection mechanism, the moisture content reading error is reduced, and raw material waste caused by misjudgment is reduced fundamentally. The control mechanism coordinates the impurity removing and sorting time sequence in real time, and when the metal detection sensor triggers speed reduction to remove scrap iron, the material collecting waiting time and the sorting transportation period of the feeding mechanism are synchronously prolonged, and equipment conflicts are avoided; tobacco leaves fall into the sorting system from the removing system through gravity, transfer pollution is avoided, and a continuous and efficient treatment process is formed.

Description

TECHNICAL FIELD

[0001] The patent relates to the field of reconstituted tobacco production dust removal equipment, and particularly relates to a sorting method for aerosol generating substrate. BACKGROUND

[0002] In the production process of aerosol generating substrate, the problems of impurity residues and uneven moisture content after tobacco leaf curing and cutting have long restricted product quality. On the one hand, dust and iron filings in the production environment are easily mixed in the tobacco leaf material. Traditional negative pressure dust removal equipment can only remove dust, but iron filings will remain due to their magnetic properties and will enter the subsequent process with the tobacco leaf. On the other hand, uneven heating during the curing stage causes the moisture content of some tobacco leaves to deviate from the standard range, and reprocessing is required to improve the pass rate.

[0003] Although the existing technology can independently handle impurities or moisture content sorting, it has serious defects: residual iron filings have thermal conductivity and can distort sensor readings during moisture content detection, leading to misjudgment of over-dried or over-wet tobacco leaves, reducing sorting accuracy; impurity removal and moisture content sorting as independent processes can easily cause secondary pollution during tobacco leaf transfer, and the timing sequence of equipment start and stop conflicts, causing production line congestion; moisture content misjudgment causes some qualified tobacco leaves to be incorrectly sorted into the reprocessing process, increasing energy consumption, and over-dried or over-wet tobacco leaves become waste due to inaccurate repair, reducing raw material utilization.

[0004] Therefore, an integrated solution that can simultaneously solve impurity removal and accurate moisture content sorting is urgently needed, especially to eliminate the physical interference of iron filings on moisture detection and optimize the collaborative operation control logic of impurity removal and unqualified product sorting. SUMMARY

[0005] The present invention aims to overcome the interference of pre-impurity removal on the accuracy of moisture content detection by reducing iron filings and dust, and optimize the timing control of collaborative operation of impurity removal and unqualified product sorting to improve the pass rate and resource utilization of reconstituted tobacco production. The patent provides the following technical solutions:

[0006] In a first aspect, a sorting method for aerosol generating substrate is provided, which includes: step S1: the aerosol generating substrate is transported by a transportation mechanism to a dust removal mechanism and a magnetic scrap removal mechanism for impurity removal; step S2: the aerosol generating substrate enters a feeding mechanism from the transportation mechanism and accumulates to a specific weight, and the feeding mechanism feeds the dynamic detection mechanism; step S3: the dynamic detection mechanism measures the moisture content of the aerosol generating substrate and performs positioning feeding according to the moisture content.

[0007] Further, the dust removal mechanism, the magnetic scrap removal mechanism, the feeding mechanism, and the dynamic detection mechanism are driven by a control mechanism.

[0008] Further, the step S1 comprises: step S11, the control mechanism controls the dust removal mechanism to keep the intermittent operation mode to perform negative pressure adsorption to remove dust from the aerosol generating substrate; step S12, the magnetic scrap removal mechanism detects the iron scrap from the aerosol generating substrate; step S13, if the iron scrap is detected, the magnetic scrap removal mechanism transmits the iron scrap detection signal to the control mechanism; and step S14, the control mechanism controls the magnetic scrap removal mechanism to remove the iron scrap by electromagnetic attraction and simultaneously reduces the transportation speed of the transportation mechanism.

[0009] Further, in the step S3, the magnetic attraction range does not affect the working ranges of the dust removal mechanism, the feeding mechanism and the dynamic detection mechanism; in the step S13, the iron scrap is attracted by the magnetic scrap removal mechanism in the magnetic attraction range and falls by gravity after leaving the magnetic attraction range; and in the step S14, when the transportation mechanism reduces the running speed, the control mechanism simultaneously prolongs the time for the feeding mechanism to wait for the collected material and the time for the dynamic detection mechanism to separate the transported material.

[0010] Further, the step S2 comprises: step S21, the weight sensor in the feeding mechanism detects the weight of the aerosol generating substrate in real time; step S22, when the weight of the aerosol generating substrate is equal to the set standard weight, the weight sensor transmits the weight detection signal to the control mechanism; and step S23, the control mechanism controls the feeding mechanism to feed the material to the dynamic detection mechanism.

[0011] Further, in the step S22, the standard weight is 38-46 kg, 46-54 kg or 54-60 kg.

[0012] Further, the step S3 comprises: step S31, the water content detection instrument in the dynamic detection mechanism detects the water content and transmits the water content detection signal to the control mechanism; step S32, the control mechanism controls the detection straight line module in the dynamic detection mechanism to position; and step S33, the dynamic detection mechanism feeds the material to the positioned transportation assembly.

[0013] Further, in the step S3, if the water content of the water content is 11-15%, the dynamic detection mechanism feeds the aerosol generating substrate into the qualified product transportation assembly; if the water content of the water content is less than 11%, the dynamic detection mechanism feeds the aerosol generating substrate into the over-dry transportation assembly; and if the water content of the water content is greater than 15%, the dynamic detection mechanism feeds the aerosol generating substrate into the over-wet transportation assembly.

[0014] Further, when the aerosol generating substrate is put into the over-wet transportation assembly, the drying assembly is provided to rework the aerosol generating substrate; when the aerosol generating substrate is put into the over-dry transportation assembly, the humidifying assembly is provided to rework the aerosol generating substrate; the qualified product transportation assembly, the over-wet transportation assembly and the over-dry transportation assembly are consistent with the running direction of the transportation mechanism; the qualified product transportation assembly, the over-wet transportation assembly and the over-dry transportation assembly are arranged below the dynamic detection mechanism.

[0015] Further, the aerosol generating substrate falls into the feeding mechanism from the transportation mechanism, and the end midpoint of the transportation mechanism is the same as the extension line of the center point of the feeding mechanism; the dynamic detection mechanism is arranged below the feeding mechanism.

[0016] The patent has the following beneficial effects:

[0017] 1. The patent provides a sorting method for aerosol generating substrates, which distinguishes the impurity removal stage, the quantitative feeding stage and the moisture content sorting stage in the process, and the three stages work cooperatively under the coordination of the control mechanism, thereby improving the detection accuracy of the moisture content of the aerosol generating substrate and the accuracy of sorting according to the moisture content.

[0018] 2. In the patent, the magnetic attraction scrap removal mechanism removes iron scraps to avoid the interference of the thermal conductivity of the iron scraps on the moisture content detector, and after the impurities are removed, the aerosol generating substrate enters the dynamic detection mechanism, the moisture content reading error is reduced, and the accuracy of sorting qualified aerosol generating substrates, over-dry aerosol generating substrates and over-wet aerosol generating substrates according to the moisture content is ensured, thereby reducing the waste of raw materials caused by misjudgment from the source.

[0019] 3. In the patent, the control mechanism synchronously prolongs the material collection waiting time of the feeding mechanism and the sorting transportation cycle when the metal detection sensor triggers the speed reduction to remove iron scraps, thereby avoiding equipment conflicts; the tobacco falls into the sorting system from the removal system by gravity, thereby avoiding transfer pollution and forming a continuous and efficient processing flow.

[0020] 4. In the patent, the qualified tobacco is directly sent to the subsequent process through accurate moisture content sorting, the over-dry aerosol generating substrate and the over-wet aerosol generating substrate are reprocessed through directional humidification or drying to meet the standard for reuse, and the raw material waste rate is reduced; at the same time, the iron scraps and dust are synchronously recovered in the impurity removal link, thereby realizing the recycling of waste materials.

[0021] 5. In the patent, the magnetic attraction range of the magnetic attraction scrap removal mechanism and the working range of other mechanisms avoid electromagnetic interference with the detection elements; the iron scrap collection box is embedded in the lateral gap of the sorting system support frame, thereby having high space utilization; the vertical coaxial design of the transportation mechanism and the feeding mechanism ensures zero deflection of the tobacco falling.

[0022] 6、In this patent, the intermittent start-stop negative pressure dust removal and the scrap iron removal speed reduction period partially overlap, reducing the overall energy consumption; the automatic linkage of standard weight feeding and moisture content sorting reduces the cost of manual intervention.

[0100] The aerosol-forming substrate can be in the form of a plug comprising aerosol-forming material defined by paper or other wrapper material. Where the aerosol-forming substrate is in the form of a plug, the entire plug including any wrapper paper is considered to be the aerosol-forming substrate.

[0101] Preferably, the aerosol-forming substrate comprises a plug comprising a mass of homogenized tobacco material or other aerosol-forming material surrounded by a wrapper.

[0102] In the present patent, aerosol former is used to describe any suitable known compound or mixture of compounds which, in use, facilitates the formation of an aerosol and which is substantially resistant to thermal degradation at the operating temperature of the aerosol-generating article.

[0103] Suitable aerosol formers are known in the art and include, but are not limited to, polyhydric alcohols such as propylene glycol, triethylene glycol, 1,3-butanediol and glycerol; esters of polyhydric alcohols such as glycerol monoacetate, glycerol diacetate or glycerol triacetate; and aliphatic esters of mono-, di- or poly-carboxylic acids such as dimethyl dodecanedioate and dimethyl tetradecanedioate. Preferred aerosol formers are polyhydric alcohols or mixtures thereof such as propylene glycol, triethylene glycol, 1,3-butanediol and most preferred glycerol.

[0105] Preferably, the aerosol-forming substrate has an aerosol former content of greater than 5% by dry weight. More preferably, the aerosol-forming substrate can have an aerosol former content of between about 5% and about 30% by dry weight. In one embodiment, the aerosol-forming substrate has an aerosol former content of about 20% by dry weight.

[0106] Tobacco sheet can be manufactured by processes known in the art including roll-pressing, slurry-dense and paper-making methods to include the aerosol-forming substrate for use in the homogenised tobacco sheet in the aerosol-generating article.

[0107] In the present patent, sheet denotes a laminar element having a width and length substantially greater than its thickness.

[0108] In the present patent, the aerosol-forming substrate comprises an aggregated textured sheet of homogenised tobacco material.

[0109] In the present patent, textured sheet denotes a sheet that has been crimped, embossed, impressed, perforated or otherwise deformed. The aerosol-forming substrate can comprise an aggregated textured sheet of homogenised tobacco material comprising a plurality of spaced apart notches, protrusions, perforations or combinations thereof.

[0112] The moving module is an automatic upgrade unit of linear guide rail, linear motion module, and ball screw linear transmission mechanism. The linear and curved motion of the load can be realized by the combination of various units, making the automation of light load more flexible and the positioning more accurate. The moving module can be divided into three types: synchronous belt type, ball screw type, and linear motor type.

[0113] The belt of the synchronous belt type moving module is installed on the transmission shaft on both sides of the linear module. The belt is fixed with a sliding block for increasing the workpiece of the device as the power input shaft. When there is input, the sliding block moves by driving the belt. The synchronous belt type linear module is usually designed to control the tightness of the belt movement on one side, which facilitates the debugging of the device during the production process. The synchronous belt type linear module can increase the rigid guide rail to improve the rigidity of the linear module according to different load needs. The load upper limit of different specifications of linear modules is different. The accuracy of the synchronous belt type linear module depends on the quality of the belt and the processing process in the combination, and the control of the power input will also affect the accuracy.

[0114] The ball screw type moving module is an ideal product that converts rotary motion to linear motion or linear motion to rotary motion. The ball screw is composed of a screw, a nut, and balls. Its function is to convert rotary motion to linear motion, which is a further extension and development of the ball screw. The significance of this development is to change the bearing from rolling motion to sliding motion. Due to its small frictional resistance, the ball screw is widely used in various industrial equipment and precision instruments. It can achieve high-precision linear motion under high load.

[0115] The control box is a power distribution equipment designed for power, lighting distribution, and motor control in various buildings. It is suitable for indoor wall hanging and outdoor floor installation. It is mainly used for fire pump control, submersible pump control, fire fan control, fan control, lighting distribution control, and other specific application scenarios. The control mode of the control box is diverse, including direct start control, star-delta step-down start control, self-coupling step-down start control, frequency converter start control, soft start control, etc. It can also use disconnectors and fuse-type switches as isolation breaking points.

[0116] For all other terms used in this patent, it is intended to have the meanings as generally understood by those of ordinary skill in the art, particularly in light of the specification and drawings, and it is intended that the patent be interpreted as having the meaning as specifically set forth herein.

[0119] In order to make the purpose, technical scheme and advantages of the application more clear, the embodiments of the application will be further described in detail below with reference to the drawings.

[0120] A sorting method for aerosol generating substrate, please refer to Figure 1 The control mechanism serves as the core mechanism in the sorting method, and can receive signals from the dust removal mechanism, the magnetic scrap removal mechanism, the feeding mechanism and the dynamic detection mechanism and drive them to work. The magnetic attraction range does not affect the working range of the dust removal mechanism, the feeding mechanism and the dynamic detection mechanism. The control mechanism is an independently arranged control box.

[0121] The sorting method comprises the following steps: S1: the aerosol generating substrate is transported by the conveying mechanism to the dust removal mechanism and the magnetic scrap removal mechanism for impurity removal.

[0122] S11: the control mechanism controls the dust removal mechanism to keep an intermittent operation mode to perform negative pressure adsorption to remove dust from the aerosol generating substrate;

[0123] S12: the magnetic scrap removal mechanism detects iron scraps from the aerosol generating substrate;

[0124] S13: if iron scraps are detected, the magnetic scrap removal mechanism transmits an iron scrap detection signal to the control mechanism;

[0125] Step S14: the control mechanism controls the magnetic debris removal mechanism to remove iron filings by electromagnetic suction and simultaneously reduces the conveying speed of the conveying mechanism.

[0126] Specifically, when the aerosol generating substrate is running through the conveying mechanism, the control mechanism controls the dust removal mechanism 200 to start and keep intermittent operation mode, so as to perform negative pressure adsorption dust removal on all passing aerosol generating substrates. After the aerosol generating substrate leaves the dust removal mechanism and enters the magnetic debris removal mechanism, the detection, speed regulation, adsorption and collection working mode is adopted.

[0127] The metal detection piece is used to detect whether the aerosol generating substrate conveyed on the tobacco conveying belt contains iron filings. If it is detected that the aerosol generating substrate contains iron filings, a signal is sent to the control mechanism, which immediately controls the tobacco conveying belt to reduce the conveying speed, and controls the electromagnetic suction piece to work by electrification, so as to suck the iron filings in the aerosol generating substrate to the bottom of the iron filings conveying belt. The iron filings conveying belt conveys the sucked iron filings to the magnetic suction range away from the electromagnetic suction piece. At this time, the iron filings at the bottom of the iron filings conveying belt fall into the iron filings collection piece under the action of gravity, so as to ensure that the iron filings in the aerosol generating substrate can be completely removed.

[0128] After the aerosol generating substrate passes through the dust removal mechanism and the magnetic debris removal mechanism, the impurities are removed, and then falls into the feeding mechanism. The extension line of the midpoint of the end of the conveying mechanism and the center point of the feeding mechanism is the same.

[0129] When the conveying mechanism reduces the running speed, the control mechanism synchronously prolongs the time for the feeding mechanism to wait for the collected material and the time for the dynamic detection mechanism to sort the conveying.

[0130] Step S2: When the aerosol generating substrate enters the feeding mechanism from the conveying mechanism and accumulates to a specific weight, the feeding mechanism feeds the material to the dynamic detection mechanism.

[0131] Step S21: The weight sensor in the feeding mechanism detects the weight of the aerosol generating substrate in real time.

[0132] Step S22: When the weight of the aerosol generating substrate is equal to the set standard weight, the weight sensor transmits a weight detection signal to the control mechanism.

[0133] Step S23: The control mechanism controls the feeding mechanism to feed the material to the dynamic detection mechanism.

[0134] The aerosol generating substrate enters the feeding bin through the top opening of the feeding bin. At this time, the feeding cover plate is located at the outlet of the feeding bin to cover the bottom end of the feeding bin. The weight of the aerosol generating substrate in the feeding bin is monitored in real time by the weight sensor and compared with the set standard weight.

[0135] When the weight sensor detects that the weight of the aerosol generating substrate in the feeding bin is equal to the standard weight, the weight sensor sends a signal to the control mechanism, and the control mechanism receives the signal to control the feeding linear module to move the bottom feeding cover plate. The dynamic detection mechanism is arranged below the feeding mechanism, and the aerosol generating substrate originally accumulated in the feeding bin falls into the detection bin of the dynamic detection mechanism under the action of gravity.

[0136] When the weight sensor detects that the weight of the aerosol generating substrate in the feeding bin is equal to the standard weight, the weight sensor sends a signal to the control mechanism, and the control mechanism receives the signal to control the feeding linear module to move the bottom feeding cover plate. The dynamic detection mechanism is arranged below the feeding mechanism, and the aerosol generating substrate originally accumulated in the feeding bin falls into the detection bin of the dynamic detection mechanism under the action of gravity.

[0137] In this embodiment, the standard weight is set to 50 kg.

[0138] It is particularly pointed out that the detection bin should be reset to the lower side of the feeding bin after the directional feeding is completed so as to quantitatively feed the aerosol generating substrate.

[0139] Step S3: The dynamic detection mechanism measures the water content of the aerosol generating substrate and performs directional feeding according to the water content.

[0140] Step S31: The water content detector in the dynamic detection mechanism detects the water content and transmits the water content detection signal to the control mechanism;

[0141] Step S32: The control mechanism controls the detection linear module in the dynamic detection mechanism to perform positioning;

[0142] Step S33: The dynamic detection mechanism feeds the positioned transportation assembly.

[0143] After the standard weight of the aerosol generating substrate enters the detection bin, the water content detector starts to detect the water content of the aerosol generating substrate in the detection bin and compares the detected water content with the set water content range value.

[0144] The water content of the standard water content is 11-15%, and if the water content of the aerosol generating substrate is the standard water content, the dynamic detection mechanism feeds the aerosol generating substrate into the qualified product transportation assembly, and the qualified product transportation assembly sends the aerosol generating substrate to the next process.

[0145] The water content of the over-dry water content is less than 11%, and if the water content of the aerosol generating substrate is the over-dry water content, the dynamic detection mechanism feeds the aerosol generating substrate into the over-dry transportation assembly, and the over-dry transportation assembly transports the aerosol generating substrate to the working range of the humidifying assembly, and the over-dry aerosol generating substrate is humidified by the humidifying assembly for reprocessing to increase the water content of the over-dry aerosol generating substrate.

[0146] The moisture content of the over-wet moisture content is greater than 15%. If the moisture content of the aerosol generating substrate is the over-wet moisture content, the dynamic detection mechanism puts the aerosol generating substrate into the over-wet transportation assembly, and the over-wet transportation assembly transports the aerosol generating substrate to the working range of the drying assembly. The over-wet aerosol generating substrate is dehumidified and reprocessed by the drying assembly to reduce the moisture content of the over-wet aerosol generating substrate.

[0147] The moisture content detector determines which type of moisture content the moisture content of the aerosol generating substrate belongs to, and transmits a signal to the control mechanism. The control mechanism controls the dynamic detection mechanism to be laterally displaced to the qualified product transportation assembly, the over-wet reprocessing mechanism or the over-dry reprocessing mechanism for feeding.

[0148] When the control mechanism moves the detection bin along the long straight line module to the corresponding transportation assembly, the control mechanism controls the detection straight line module to move the bottom detection cover plate. The aerosol generating substrate originally accumulated in the detection bin falls into the corresponding transportation assembly below under the action of gravity. After the aerosol generating substrate in the detection bin falls, the control mechanism controls the detection straight line module to move the detection cover plate to the bottom of the detection bin.

[0149] When the aerosol generating substrate is put into the over-wet transportation assembly, a drying assembly is provided to dehumidify and reprocess the aerosol generating substrate. When the aerosol generating substrate is put into the over-dry transportation assembly, a humidifying assembly is provided to humidify and reprocess the aerosol generating substrate. The qualified product transportation assembly, the over-wet transportation assembly and the over-dry transportation assembly are consistent with the running direction of the transportation mechanism. The qualified product transportation assembly, the over-wet transportation assembly and the over-dry transportation assembly are arranged below the dynamic detection mechanism.

[0150] A sorting system suitable for the sorting method of the aerosol generating substrate described above, please refer to Figure 2 The sorting system includes a foreign matter removing device, a sorting device and a control mechanism 900. The height of the foreign matter removing device is greater than the height of the sorting device so that the aerosol generating substrate falls into the sorting device by gravity after leaving the foreign matter removing device. The width of the foreign matter removing device is less than the width of the sorting device, and the extension line of the symmetry axis of the foreign matter removing device should coincide with the extension line of the symmetry axis of the sorting device.

[0151] Please refer to Figures 3-4 The foreign matter removing device includes a transportation mechanism 100, a magnetic scrap removing mechanism 300 and a dust removing mechanism 200. The transportation mechanism 100 transports the aerosol generating substrate. The dust removing mechanism 200 removes dust in the aerosol generating substrate by negative pressure adsorption. The magnetic scrap removing mechanism 300 adsorbs iron filings in the aerosol generating substrate by electromagnetic force.

[0152] The sorting device comprises a feeding mechanism 400, a dynamic detection mechanism 500, a qualified product conveying assembly 600, a too-wet conveying assembly 710, and a too-dry conveying assembly 810. The feeding mechanism 400 quantitatively feeds the dynamic detection mechanism 500. The dynamic detection mechanism 500 detects the water content of the aerosol generating substrate and conveys the aerosol generating substrate to the corresponding qualified product conveying assembly 600, too-wet conveying assembly 710, or too-dry conveying assembly 810 according to the water content.

[0153] In particular, the aerosol generating substrate falls into the feeding mechanism 400 after being cleaned of impurities on the conveying mechanism 100. The end point of the conveying mechanism 100 and the center point of the feeding mechanism 400 are located on the same vertical line.

[0154] The control mechanism 900 is a control box that independently controls the impurity removal device and the sorting device and can adjust the working process when transitioning between the impurity removal device and the sorting device. When the conveying mechanism 100 reduces the running speed, the control mechanism 900 synchronously extends the time for the feeding mechanism 400 to wait for the collection of materials and the time for the dynamic detection mechanism 500 to sort and convey.

[0155] The impurity removal device comprises a conveying mechanism 100, a dust removal mechanism 200, a magnetic scrap removal mechanism 300, and a control mechanism 900. The conveying mechanism 100 and the magnetic scrap removal mechanism 300 are long conveying belt devices. The dust removal mechanism 200 is a cubic device. The conveying mechanism 100 is arranged below the magnetic scrap removal mechanism 300 and the dust removal mechanism 200, so that the dust removal mechanism 200 adsorbs dust by negative pressure suction, and the magnetic scrap removal mechanism 300 adsorbs iron filings by magnetic force.

[0156] The conveying mechanism 100 runs in the horizontal direction, the magnetic scrap removal mechanism 300 runs in the vertical direction, and the dust removal mechanism 200 releases the negative pressure adsorption force downward. The running direction of the conveying mechanism 100 and the running direction of the magnetic scrap removal mechanism 300 are perpendicular to each other along the projection line of the vertical direction. Therefore, only the range of the magnetic adsorption needs to be fixed to make the aerosol generating substrate on the conveying mechanism 100 pass through the detection and adsorption of the magnetic scrap removal mechanism 300.

[0157] The magnetic adsorption range can cover the width of the conveying mechanism 100. In particular, the magnetic adsorption range should also be smaller than the length of the magnetic scrap removal mechanism 300.

[0158] The conveying mechanism 100 comprises a tobacco conveying belt 110, a tobacco conveying roller 120, and a tobacco conveying bracket 130. The tobacco conveying bracket 130 comprises a horizontal bar with inwardly recessed grooves. The two end groove through holes in the middle of the horizontal bar are used to fix the tobacco conveying roller 120. A relatively narrow horizontal bar extends above the horizontal bar to fix the filter 210 of the dust removal mechanism 200. The two ends below the horizontal bar are respectively fixed with support feet to support downwardly.

[0159] The tobacco transporting roller 120 is a cylindrical structure, and the two ends of the tobacco transporting roller 120 are fixed to the tobacco transporting support 130 and rotate around the fixed points. The two tobacco transporting rollers 120 are arranged in parallel and at the same height, and the two tobacco transporting supports 130 connected to the two tobacco transporting rollers 120 are fixedly connected by a cross bar to form a firm square support. The tobacco transporting belt 110 forms a ring-shaped transporting belt through the tensioning of the tobacco transporting roller 120, and the tobacco transporting belt 110 moves synchronously under the rotation of the tobacco transporting roller 120 to transport the aerosol generating substrate.

[0160] The dust removal mechanism 200 includes a filter 210, a negative pressure fan 220, a dust collection pipe 230, and a fan support 240. The negative pressure fan 220 is arranged on the fan support 240, the filter 210 is fixed above the transporting mechanism 100 to block the negative pressure fan 220 from adsorbing the aerosol generating substrate, and the dust adsorbed by the negative pressure fan 220 from the aerosol generating substrate is collected through the dust collection pipe 230.

[0161] The fan support 240 is a square main frame, and four supporting feet are arranged at the bottom of the main frame and support downward. The width of the fan support 240 should be greater than the width of the transporting mechanism 100, and the height of the fan support 240 should be greater than the sum of the height of the transporting mechanism 100, the height of the negative pressure fan 220, and the height of the working space of the negative pressure fan 220.

[0162] The dust collection pipe 230 is a cubic structure, and a through hole is arranged in the interior to uniformly collect the dust adsorbed by the negative pressure fan 220. The dust collection pipe 230 is arranged at the top end of the negative pressure fan 220 and communicates with the negative pressure fan 220.

[0163] The size of the filter 210 is equal to that of the tobacco transporting belt 110, so that the aerosol generating substrate can be completely covered in the filter 210 and will not be sucked away by the negative pressure fan 220. It is particularly noted that the filter 210 is fixed to the cross bar of the tobacco transporting support 130, and a thin cavity exists between the filter 210 and the tobacco transporting belt 110 to place the aerosol generating substrate. In this way, the activity space of the aerosol generating substrate can be controlled when the negative pressure fan 220 performs negative pressure adsorption, so as to prevent the aerosol generating substrate from scattering from the side of the tobacco transporting belt 110.

[0164] The filter 210 is a mesh structure with pores, and the diameter of the pores is 2 mm. In this way, the filter 210 can not only adsorb dust by the negative pressure fan 220, but also prevent the aerosol generating substrate from being sucked out of the pores by the negative pressure fan 220.

[0165] It is particularly noted that the filter 210 is made of a non-ferromagnetic material, so as to avoid the interference of the filter 210 with the working process of the magnetic dust removal mechanism 300. The purpose of the dust removal mechanism 200 is to remove dust impurities in the aerosol generating substrate.

[0166] The dust removal mechanism 200 is intermittently operated by starting and stopping alternately, the starting time is 30s, and the stopping time is 10s, so that the aerosol generating substrate on the tobacco conveying belt 110 can pass through the working area of the negative pressure fan 220.

[0167] Please refer to Figure 5 The magnetic dust removal mechanism 300 includes a scrap iron carrying assembly 310, a metal detection piece 320, an electromagnetic suction piece 330, a support assembly 340, and a scrap iron collecting piece 350. The scrap iron carrying assembly 310, the metal detection piece 320, and the electromagnetic suction piece 330 are arranged on the support assembly 340. The metal detection piece 320 can transmit a signal detected by the scrap iron to the control mechanism 900.

[0168] The scrap iron carrying assembly 310 includes a scrap iron conveying belt 311 and a scrap iron conveying roller 312, and the scrap iron conveying roller 312 is connected through a roller shaft support 342. The roller shaft support 342 includes a horizontal rod with an inwardly recessed groove, and two end groove through holes in the middle of the horizontal rod are used to fix the scrap iron conveying roller 312. The scrap iron conveying roller 312 is a cylindrical structure, and the two ends of the scrap iron conveying roller 312 are fixed with the horizontal rod with an inwardly recessed groove and rotate around the fixed points as the center. Two scrap iron conveying rollers 312 are arranged in parallel and at the same height, and two horizontal rods connected with the two scrap iron conveying rollers 312 are fixedly connected to form a firm square support.

[0169] The scrap iron conveying belt 311 forms a ring-shaped conveying belt through the tensioning of the scrap iron conveying roller 312, and the scrap iron conveying belt 311 moves synchronously under the rotation of the scrap iron conveying roller 312. It is particularly pointed out that the electromagnetic suction piece 330 is arranged between the ring-shaped scrap iron conveying belt 311, and the scrap iron conveying belt 311 is made of non-ferromagnetic material, which can avoid the interference of the scrap iron conveying belt 311 to the magnetic attraction process of the electromagnetic suction piece 330.

[0170] The metal detection piece 320 is a metal detection sensor, which is used to detect whether the aerosol generating substrate conveyed on the tobacco conveying belt 110 contains scrap iron. If scrap iron is detected in the aerosol generating substrate, a signal is immediately sent to the control mechanism 900.

[0171] The electromagnetic suction piece 330 is an electromagnet device, which has a magnetic attraction force after being powered on. The magnetic attraction range can cover the width of the conveying mechanism 100. The control mechanism 900 can control the power-on and power-off of the electromagnetic suction piece 330. After being powered on, the magnetic attraction force of the electromagnetic suction piece 330 can attract the scrap iron in the aerosol generating substrate to the bottom scrap iron conveying belt 311 of the magnetic dust removal mechanism 300 without falling off.

[0172] The iron filings collection member 350 is arranged in the non-magnetic attraction range, and the iron filings are continuously attracted by the electromagnetic attraction member 330 and firmly attached to the bottom iron filings conveying belt 311. The iron filings conveying belt 311 rotates through the iron filings conveying roller 312, and the attracted iron filings are also displaced synchronously. When the iron filings at the position leave the magnetic attraction range of the electromagnetic attraction member 330, the magnetic attraction no longer continues, and the iron filings fall into the iron filings collection member 350 due to the gravity acting on the iron filings.

[0173] The iron filings collection member 350 is arranged at the junction of the magnetic attraction range and the non-magnetic attraction range of the electromagnetic attraction member 330. In the embodiment, the iron filings collection member 350 is arranged at the end of the iron filings conveying belt 311 and is adjacent to the tobacco conveying support 130.

[0174] The support assembly 340 further includes a conveying support frame 341, a detection support plate 343, and a magnetic attraction support plate 344. The conveying support frame 341 passes through the cavity of the annular iron filings conveying belt 311 and is fixed above the crossbar of the roller shaft frame 342. The magnetic attraction support plate 344 is fixed at one end on the conveying support frame 341 and at the other end on the electromagnetic attraction member 330. The conveying support frame 341, the roller shaft frame 342, and the electromagnetic attraction member 330 form a sandwich structure with the roller shaft frame 342 as the middle layer, and are all arranged in the cavity of the annular iron filings conveying belt 311, which can maximize the use of vertical space.

[0175] The detection support plate 343 is used to fix the metal detection member 320 on the side of the conveying support frame 341. In particular, the metal detection member 320 is a certain distance away from the iron filings belt-out assembly 310. The aerosol generating substrate removed by negative pressure dust removal first passes through the detection of the metal detection member 320 and then is attracted by the electromagnetic attraction member 330.

[0176] The conveying support frame 341 is a square main frame, and four support feet are arranged at the bottom of the main frame and support downward. The width of the conveying support frame 341 should be greater than the width of the conveying mechanism 100 and less than the distance between the iron filings conveying rollers 312. In particular, the width of the conveying support frame 341 is equal to the width of the fan support 240. The height of the conveying support frame 341 should be greater than the sum of the height of the conveying mechanism 100, the height of the magnetic attraction and iron removal mechanism 300, and the height of the working space of the electromagnetic attraction member 330. In particular, the height of the conveying support frame 341 is equal to the height of the fan support 240.

[0177] The dust removal mechanism 200 and the magnetic attraction and iron removal mechanism 300 perform impurity removal work on the aerosol generating substrate below in parallel. The dust removal mechanism 200 and the magnetic attraction and iron removal mechanism 300 are controlled by the control mechanism 900, but the dust removal mechanism 200 and the magnetic attraction and iron removal mechanism 300 do not affect each other. The dust removal mechanism 200 is used to remove dust impurities in the aerosol generating substrate, and the magnetic attraction and iron removal mechanism 300 is used to remove iron filings impurities in the aerosol generating substrate.

[0185] In the length direction of the transverse direction, the length of the qualified product conveying assembly 600 should be less than the length of the feeding mechanism 400 to avoid collision between the qualified product conveying assembly 600 and the bottom of the feeding mechanism 400; the sum of the length of the qualified product conveying assembly 600, the length of the over-dry conveying assembly 810 and the length of the over-wet conveying assembly 710 should be less than the length of the dynamic detection mechanism 500, so that the dynamic detection mechanism 500 can feed within the working range.
