Description

Technical Field

[0002] To meet diverse consumer needs, existing cigarette products typically incorporate flavored granules (commonly known as "flavor capsules") during the cigarette manufacturing process. These capsules enhance the aroma during inhalation, thereby improving the consumer's smoking experience.

[0003] In the prior art, conveying equipment is usually used to transport granular materials. For example, the equipment disclosed in publication number CN115581314A can be used to transport granular materials. This equipment includes a guide rail assembly and a feeding unit set on the guide rail assembly. The feeding unit is used to receive and transport granular materials. When the feeding unit moves to a certain position on the guide rail assembly, the lower rail can control the opening or closing of the feeding unit's outlet to realize the feeding of the feeding unit.

[0063] This invention provides a particulate material conveying device with an inlet and an outlet. The device includes a track assembly, a feeding unit, a drive assembly, and a negative pressure assembly. The feeding unit is mounted on the track assembly and can move along the track assembly between the inlet and outlet positions. The feeding unit has an adsorption port for adsorbing particulate material. The drive assembly is connected to the feeding unit and drives it to move along the track assembly. The negative pressure assembly is connected to the feeding unit and provides negative pressure to the adsorption port, adsorbing the particulate material thereon. The negative pressure assembly provides negative pressure to the feeding unit, allowing it to receive and convey particulate material through negative pressure adsorption. This better prevents collisions during material handling and conveying, thus reducing the risk of accidental breakage and improving the stability of the material conveying process.

[0064] Please refer to the following: Figures 1 to 8 This embodiment provides a particulate material conveying device 100, which is mainly used to solve the problem that particulate materials are easily damaged due to collisions when conveying particulate materials in the prior art. Specifically, the particulate material is tobacco particulate material.

[0065] The granular material conveying device 100 has an inlet position 101 and an outlet position 102. The granular material conveying device 100 includes a track assembly 10, a feeding unit 20, a drive assembly 30, and a negative pressure assembly 40. The feeding unit 20 is disposed on the track assembly 10 and can move along the track assembly 10 between the inlet position 101 and the outlet position 102. The feeding unit 20 has an adsorption port 21 for adsorbing granular material. When the feeding unit 20 moves to the inlet position 101, the adsorption port 21 of the feeding unit 20 adsorbs and receives granular material from the upstream equipment, and then moves along the track assembly 10 until it reaches the outlet position 102. At this point, the granular material on the adsorption port 21 falls into the downstream equipment, thereby realizing the conveying of granular material.

[0066] The drive assembly 30 is connected to the feeding unit 20 and drives the feeding unit 20 to move along the track assembly 10. In other words, the drive assembly 30 provides the power to move the feeding unit 20, thereby driving the feeding unit 20 to move. The track assembly 10 better guides the movement direction and position of the feeding unit 20, ensuring its movement between the feeding position 101 and the discharging position 102, and ensuring the stability of the granular material conveying and docking.

[0067] The negative pressure component 40 is connected to the feeding unit 20 and is used to provide negative pressure to the adsorption port 21 to adsorb particulate material at the adsorption port 21. That is, the negative pressure component 40 provides adsorption power to the feeding unit 20, thereby stably adsorbing particulate material at the adsorption port 21. Specifically, the negative pressure component 40 provides negative pressure to the feeding unit 20 in the entire area where the feeding unit 20 moves on the track assembly 10. Therefore, whenever the feeding unit 20 moves to any area on the track assembly 10, negative pressure exists at the adsorption port 21, thus stably adsorbing particulate material. Furthermore, when the feeding unit 20 moves to the discharge position 102, downstream equipment can provide greater adsorption force to collect the particulate material from the feeding unit 20, thereby achieving particulate material adsorption. The negative pressure component 40 can also provide negative pressure to the feeding unit 20 in the following ways: the feeding unit 20 provides negative pressure in the part of the track assembly 10 that moves on it. For example, when the feeding unit is at the feeding position and when it moves from the feeding position to the discharging position, the negative pressure component 40 provides negative pressure to achieve stable receiving and conveying of particulate materials. When the feeding unit is at the discharging position 102, the negative pressure component 40 does not provide negative pressure, so that the particulate materials can automatically fall from the adsorption port 21.

[0068] It is understandable that existing granular material conveying equipment relies on the gravity of the granular material itself to receive and discharge it. Granular materials are prone to collisions, which can lead to breakage.

[0069] The particulate material conveying device 100 provided in this embodiment is equipped with the negative pressure component 40 and the adsorption port 21 is provided in the feeding unit 20. Thus, particulate materials can be picked up and conveyed by negative pressure adsorption. During docking and conveying, the particulate materials are less likely to collide, thereby reducing the risk of breakage and improving the stability of particulate material conveying.

[0070] Preferably, in one embodiment, the negative pressure assembly 40 includes a gas distribution seat 41, a rotating seat 42, an output interface 43, a rotating seat drive mechanism 44, and a negative pressure suction device. The gas distribution seat 41 has a gas distribution chamber 411. The rotating seat 42 is rotatably mounted on the gas distribution seat 41, and the rotating seat 42 has a gas distribution channel 421 for communicating with the gas distribution chamber 411. The output interface 43 is disposed on the rotating seat 42 and communicates with the gas distribution channel 421, and the output interface 43 is connected to the feeding unit 20 via a pipeline. The rotating seat drive mechanism 44 is connected to the rotating seat 42 to drive the rotating seat 42 to rotate. The negative pressure suction device is connected to the gas distribution seat 41 to provide negative pressure to the gas distribution chamber 411. Since the output interface 43 is connected to the feeding unit 20 via a pipeline and also to the gas distribution channel 421, the negative pressure suction device can provide negative pressure to the feeding unit 20, thereby adsorbing particulate material onto the adsorption port 21. The rotating seat drive mechanism 44 allows the rotating seat 42 to rotate relative to the gas distribution seat 41, better adapting to the movement of the feeding unit 20 and ensuring stable gas distribution. The negative pressure suction device can be any device that provides suction force, such as an air pump.

[0071] Preferably, in one embodiment, the rotational speed of the rotating seat 42 is the same as the moving speed of the unloading unit 20. That is, in this embodiment, the rotational speed at which the rotating seat drive mechanism 44 drives the rotating seat 42 to rotate is consistent with the moving speed at which the drive assembly 30 drives the unloading unit 20. This better ensures the reliability of the connection between the unloading unit 20 and the negative pressure assembly 40, and better ensures the stability of the airflow in the unloading unit 20. Specifically, in one embodiment, the track in the track assembly 10 is a circular track, and the linear velocity of the rotating seat 42 is consistent with the linear velocity of the moving unloading unit 20.

[0072] Preferably, in one embodiment, the gas distribution channel 421 and the gas distribution chamber 411 are mutually isolated in the area on the rotating seat 42 corresponding to the discharge position 102. That is, the gas distribution channel 421 and the gas distribution chamber 411 are not interconnected in the area on the rotating seat 42 corresponding to the discharge position 102. Therefore, when the output port 43 rotates to this position, the output port 43 cannot provide negative pressure to the feeding unit 20, causing the adsorption port 21 to no longer adsorb particulate material, and the particulate material will fall due to its own gravity. Conversely, the gas distribution channel 421 and the gas distribution chamber 411 are interconnected in the area on the rotating seat 42 corresponding to the feed position 101 and the area on the rotating seat 42 corresponding to the area from the feed position 101 to the discharge position 102. In other words, the area on the rotating seat 42 corresponding to the feeding position 101, where the air distribution channel 421 and the air distribution chamber 411 are interconnected, ensures that when the output port 43 rotates to this position, it provides negative pressure to the feeding unit 20, resulting in negative pressure at the adsorption port 21. This allows for the adsorption of particulate material, thus ensuring a more stable intake of the particulate material from upstream. Furthermore, the area on the rotating seat 42 corresponding to the feeding position 101 to the discharge position 102, where the air distribution channel 421 and the air distribution chamber 411 are also interconnected, ensures that when the output port 43 rotates to this position, it also provides negative pressure to the feeding unit 20, thus stably conveying the collected particulate material to the discharge position 102. For example... Figure 5As shown, the area on the rotating seat 42 corresponding to the discharge position 102 is region I; the area on the rotating seat 42 corresponding to the feed position 101 and the area from the feed position 101 to the discharge position 102 is region V. The gas distribution channel 421 and the gas distribution chamber 411 in region I of the rotating seat 42 are mutually isolated, so the negative pressure component 40 will not provide negative pressure to the feeding unit 20 in this area; the gas distribution channel 421 and the gas distribution chamber 411 in region V of the rotating seat 42 are interconnected, so the negative pressure component 40 will provide negative pressure to the feeding unit 20 in this area. Since the rotating seat 42 rotates continuously under the drive of the rotating seat drive mechanism 44, it drives the output interface 43 to move back and forth synchronously between region I and region V, thereby cyclically opening and closing the air path to facilitate the feeding, conveying, and discharging of particulate materials. In other words, in this embodiment, the negative pressure component 40 provides negative pressure to the feeding unit 20 only in a portion of the area. During the receiving and conveying process of the feeding unit 20, the negative pressure component 40 provides negative pressure to the feeding unit 20, thereby ensuring stable receiving and conveying of the granular material. However, during the feeding process, the negative pressure component 40 does not provide negative pressure to the feeding unit 20, allowing the granular material to be fed by its own gravity. With this structure, there is no need to set up a corresponding adsorption structure in the downstream equipment, simplifying the downstream equipment; and since no adsorption force in two directions is applied to the granular material during the feeding process, damage to the granular material can be better avoided.

[0073] Specifically, in one embodiment, the specific structure for the negative pressure component 40 to provide negative pressure to the feeding unit 20 only in a certain area is as follows: the air distribution chamber 411 includes a first chamber 4111, a second chamber 4112, and a third chamber 4113. The first chamber 4111 is disposed on the inner side of the air distribution seat 41 and communicates with the negative pressure suction device. The second chamber 4112 is disposed on the circumferential surface of the air distribution seat 41 and is disposed at the position corresponding to the V region. The second chamber 4112 communicates with the first chamber 4111 through the third chamber 4113. In other words, the second cavity 4112 is only provided on the circumferential surface of the gas distribution seat 41 at the position corresponding to region V. In this region, the gas distribution channel 421 can communicate with the first cavity 4111 through the second cavity 4112, thereby supplying negative pressure to the feeding unit 20. Other parts of the circumferential surface of the gas distribution seat 41 do not have the second cavity 4112, thus the gas distribution channel 421 is isolated from the first cavity 4111 in this region, and no negative pressure is supplied to the feeding unit 20. It can be understood that when there are multiple feeding positions 101 circumferentially, multiple second cavities 4112 can be provided accordingly, with adjacent second cavities 4112 spaced apart circumferentially. For example, when there are two feeding positions 101 and two discharging positions 102 circumferentially, two second cavities 4112 can be provided accordingly, with the two second cavities 4112 spaced apart circumferentially.

[0074] The rotating seat drive mechanism 44 may include a drive source and a transmission mechanism. The transmission mechanism may be a gear transmission, so that the rotation of the rotating seat 42 can be precisely controlled through gear transmission.

[0075] Preferably, in one embodiment, multiple feeding units 20 are provided, and all feeding units 20 are arranged sequentially along the extension direction of the track assembly 10. Multiple output interfaces 43 are provided, and all output interfaces 43 are arranged sequentially along the circumference of the rotating seat 42. Each output interface 43 corresponds one-to-one with a feeding unit 20, meaning each feeding unit 20 is connected to one output interface 43 via an independent pipeline, allowing for independent air distribution to each feeding unit 20. To prevent interference between the air distributions of the output interfaces 43, more preferably, each output interface 43 is connected to an independent air distribution channel 421. That is, multiple independent air distribution channels 421 can be provided on the rotating seat 42, and one output interface 43 is connected to one air distribution channel 421. By providing multiple feeding units 20 and multiple output interfaces 43, the conveying efficiency of particulate materials can be improved.

[0076] Preferably, in one embodiment, the feeding unit 20 includes a fixed part 22 and a lifting part 23. The lifting part 23 is connected to the fixed part 22 and can rise or fall relative to the fixed part 22. The suction port 21 is disposed on the lifting part 23, and the lifting part 23 is connected to the negative pressure component 40. The track component 10 includes an annular positioning track 11 and an annular pressing track 12. The fixed part 22 is installed on the annular positioning track 11, and the lifting part 23 is installed on the annular pressing track 12. A height difference exists between some areas of the annular pressing track 12, so that when the lifting part 23 moves along the annular pressing track 12, the annular pressing track 12 can drive the lifting part 23 to rise or fall, thereby controlling the relative rise and fall between the fixed part 22 and the lifting part 23, allowing the suction port 21 to more stably receive and transfer particulate materials.

[0077] Preferably, in one embodiment, the lower part 121 (the part with a relatively lower height) of the annular pressing track 12 corresponds to the discharge position 102, and the higher part 122 (the part with a relatively higher height) of the annular pressing track 12 corresponds to the feeding position 101. That is, when the feeding unit 20 is at the feeding position 101, the lifting part 23 is at a relatively high position; and when the feeding unit 20 is at the discharge position 102, the lifting part 23 is at a relatively low position. This allows the upstream and downstream equipment to be arranged at different heights, thus facilitating the arrangement of the upstream and downstream equipment. Furthermore, this structure can also better improve the stability of the feeding unit 20 in receiving and discharging materials.

[0078] Specifically, in one embodiment, the lifting part 23 is provided with an input interface 231, and the input interface 231 is connected to the output interface 43 through a pipeline.

[0079] It is understandable that when the track in the track assembly 10 is a circular track with long and curved sides, the distance between the output interface 43 and the input interface 231 will be different when the feeding unit 20 moves to different positions on the track assembly 10. In this embodiment, the output interface 43 and the input interface 231 can be connected by a flexible hose, and the length of the hose is not less than the maximum distance between the input interface 43 and the input interface 231. Therefore, when the distance between the output interface 43 and the input interface 231 is short, the hose can have a certain deformation margin; and when the distance between the output interface 43 and the input interface 231 is long, the hose can automatically adapt to deformation and elongation, thereby ensuring stable conduction between the output interface 43 and the input interface 231 at all positions, and better ensuring the air distribution effect.

[0080] Preferably, in one embodiment, the lifting part 23 is mounted on the annular downward pressing track 12 via a cam follower 24. With the cam follower 24, during the movement of the lifting part 23, the cam follower 24 can roll on the track, thereby preventing wear between the lifting part 23 and the track and improving its service life.

[0081] Preferably, in one embodiment, the fixing part 22 is mounted on the annular positioning track 11 via a connector 25. The connector 25 includes a base plate 251 and a first roller 252 and a second roller 253 mounted on the base plate 251, the base plate 251 being used to connect with the fixing part 22. The annular positioning track 11 is located between the first roller 252 and the second roller 253, and the first roller 252 and the second roller 253 are tactilely connected to opposite sides of the track 11. That is, the connector 25 is clamped onto the annular positioning track 11 via the first roller 252 and the second roller 253, thereby allowing for force connection from at least both sides of the track, making the force distribution more stable.

[0082] The connector 25 is connected to the fixed part 22, and the connector 25 is rolled on opposite sides of the annular positioning track 11 via the first roller 252 and the second roller 253. This makes the force more balanced, can bear torque in more directions, and makes the connection between the connector 25 and the annular positioning track 11 more stable and reliable. This better ensures the force stability between the feeding unit 20 and the annular positioning track 11, and the feeding unit 20 is less likely to deviate during long-term use. At the same time, the base plate 251 also makes the installation of the feeding unit 20 more convenient. During installation, the connector 25 can be installed on the annular positioning track 11 first, and then the feeding unit can be installed, which also reduces the installation difficulty of the connector 25.

[0083] Preferably, in one embodiment, two first rollers 252 are provided, arranged side-by-side along the extension direction of the annular positioning track 11, i.e., the two first rollers 252 are rolled one after the other on the annular positioning track 11. Two second rollers 253 are provided, arranged side-by-side along the extension direction of the annular positioning track 11, i.e., the two second rollers 253 are rolled one after the other on the annular positioning track 11. This structure better ensures the balance of forces on the connecting member 25 along the extension direction of the annular positioning track 11, making it less prone to deflection along the extension direction of the annular positioning track 11. In other words, in this embodiment, the connecting member 25 is rolledly connected to the annular positioning track 11 via four rollers, thereby bearing torque in more directions and making the connection more stable and reliable.

[0084] Preferably, in one embodiment, the two first rollers 252 and the two second rollers 253 are arranged opposite each other, that is, a second roller 253 is arranged on the opposite side of one first roller 252, and another second roller 253 is arranged on the opposite side of another first roller 252. The four rollers are arranged in a rectangular structure, which can better ensure the balance of force.

[0085] Preferably, in one embodiment, the first roller 252 is rotatably connected to the inner side 111 of the annular positioning track 11, and the second roller 253 is rotatably connected to the outer side 112 of the annular positioning track 11. That is, in this embodiment, the first roller 252 and the second roller 253 are connected to opposite sides of the annular positioning track 11 in the horizontal direction, which can better utilize the horizontal space and avoid interference with other components in the equipment.

[0086] Preferably, in one embodiment, the inner side 111 of the annular positioning track 11 has an inner groove 1111, and the first roller 252 is rolletably connected to the inner groove 1111. The outer side 112 of the annular positioning track 11 has an outer groove 1121, and the second roller 253 is rolletably connected to the outer groove 1121. This can better ensure the reliability of the rollet connection between the first roller 252, the second roller 253 and the annular positioning track 11.

[0087] Preferably, in one embodiment, the axes of the first roller 252 and the second roller 253 are both vertical. That is, the first roller 252 and the second roller 253 are both horizontal rollers, the rolling surface of the first roller 252 is in rolling contact with the inner wall of the inner groove 1111, and the rolling surface of the second roller 253 is in rolling contact with the inner wall of the outer groove 1121.

[0088] Preferably, in one embodiment, the connector 25 further includes a connecting guide 254 for connecting to the drive belt of the drive assembly 30.

[0089] Preferably, in one embodiment, the connecting guide 254 is disposed at one end of the base plate 251, thereby better avoiding interference with the arrangement of the rollers.

[0090] Specifically, in one embodiment, the drive assembly 30 includes a drive wheel set 31, a drive belt 32, and a drive source. The drive belt 32 is arranged around the drive wheel set 31. The drive source and the drive wheel set 31 are used to drive the drive wheel set 31 to run, thereby driving the drive belt 32. The feeding unit 20 is connected to the drive belt 32. The drive source may be a motor.

[0091] Please refer to the following: Figures 9 to 16 Meanwhile, in one embodiment, a granular material conveying device is also provided, which includes the granular material conveying device 100 and the granular material conveying mechanism 200. The discharge position of the granular material conveying mechanism 200 is located below the feed position 101, for providing granular material to the granular material conveying device 100.

[0092] Preferably, in one embodiment, the particulate material conveying mechanism 200 includes a hopper 201, a conveyor belt assembly 202, and a blocking assembly 203. The conveyor belt assembly 202 includes a drive unit, a drive wheel 2021, a driven wheel 2022, and a conveyor belt 2023. The drive unit is connected to the drive wheel 2021 and drives the drive wheel 2021 to rotate. Specifically, the drive unit may be a motor. The driven wheel 2022 is spaced apart from the drive wheel 2021. The conveyor belt 2023 surrounds the drive wheel 2021 and the driven wheel 2022, and is located below the discharge port 2011 of the hopper 201 to receive the particulate material discharged from the discharge port 2011. When conveying particulate materials, the drive unit drives the drive wheel 2021 to rotate, thereby the drive wheel 2021 drives the conveyor belt 2023 to run, so that the conveyor belt 2023 conveys the received particulate materials to the rear in a linear movement.

[0093] The outer surface of the conveyor belt 2023 is provided with receiving holes 2024 for receiving particulate material. Particulate material falling from the discharge port 2011 can flow into the receiving holes 2024 for reception. The blocking component 203 is located behind the discharge port 2011 to block material on the conveyor belt 2023 that is outside the receiving holes 2024. The blocking component 203 is located behind the discharge port 2011 with reference to the conveying direction of the conveyor belt 2023. When the conveyor belt 2023 is running, it first passes the discharge port 2011 and then passes the blocking component 203.

[0094] It is understandable that when particulate material falls from the discharge port 2011 onto the conveyor belt 2023, some may fall into the receiving hole 2024, while others may fall onto the outer surface of the conveyor belt 2023 outside the receiving hole 2024. This results in variations in the amount of particulate material conveyed by the conveyor belt 2023 each time, making it impossible to achieve quantitative conveying of particulate material and affecting the stability of quantitative conveying. However, with the blocking component 203, after the conveyor belt 2023 receives particulate material from the discharge port 2011, the blocking component 203 can block the particulate material located outside the receiving hole 2024, thereby ensuring that the particulate material conveyed to the rear is only located in the receiving hole 2024, thus achieving quantitative conveying of particulate material and better ensuring the stability of quantitative conveying of particulate material. The size of the receiving hole 2024 can be selected according to the amount of material to be conveyed each time. For example, the size of the receiving hole 2024 can be adapted to one particulate material, so that only one particulate material can be contained in each receiving hole 2024 at a time; or, the size of the receiving hole 2024 can be adapted to multiple particulate materials, so that multiple particulate materials can be contained in each receiving hole 2024 at the same time. The size of the receiving hole 2024 can be selected according to actual needs.

[0095] The blocking component 203 includes a mounting block 2031 and a brush 2032. The mounting block 2031 is connected to the discharge port 2011. By directly connecting the mounting block 2031 to the discharge port 2011, other installation structures can be eliminated, making the overall structure more compact and simple. The brush 2032 is located at the bottom of the mounting block 2031 and above the conveyor belt 2023 to block material located on the conveyor belt 2023 above the receiving hole 2024. It is understood that tobacco particulate material is very prone to breakage, and by using the brush 2032 to block and scrape away the tobacco particulate material, breakage of the particulate material can be better avoided, thus ensuring the reliability of the conveying.

[0096] The conveying distance of the granular material conveying mechanism 200 is related to the distance between the driving wheel 2021 and the driven wheel 2022, as well as the length of the conveyor belt 2023. Long-distance conveying of granular materials can be achieved simply by adjusting the distance between the two wheels and the length of the conveyor belt 2023, making installation more convenient. Furthermore, the belt structure for conveying granular materials is simple in structure and small in size, allowing for installation in relatively narrow areas. The conveyor belt 2023 effectively picks up and linearly conveys the granular materials, better preventing breakage and ensuring more stable material transport.

[0097] Preferably, in one embodiment, multiple sets of receiving holes 2024 are arranged sequentially at intervals along the length of the conveyor belt 2023, and the spacing between adjacent sets of receiving holes 2024 is equal. By arranging multiple sets of receiving holes 2024, particulate materials can be continuously and uninterruptedly conveyed, improving conveying efficiency.

[0098] Preferably, in one embodiment, each group of receiving holes 2024 includes two receiving holes 2024, and the two receiving holes 2024 in each group are spaced apart from each other along the length of the conveyor belt 2023. That is, in this embodiment, when the conveyor belt 2023 conveys particulate material, it can convey particulate material from two receiving holes 2024 at a time, in groups. Each feeding unit 20 is provided with two suction ports 21, so that it can pick up particulate material from two receiving holes 2024 at a time. Specifically, in one embodiment, each receiving hole 2024 is adapted to one particulate material. That is, the receiving hole 2024 can only hold one particulate material at a time, and the conveyor belt 2023 conveys particulate material to the rear equipment in units of two particulate materials.

[0099] Preferably, in one embodiment, the receiving hole 2024 is circular. That is, the receiving hole 2024 has an overall circular structure, and the sidewalls of the receiving hole 2024 have an arc-shaped structure, which can better adapt to the particulate material and avoid squeezing the particulate material and causing damage.

[0100] Preferably, in one embodiment, the blocking assembly 203 further includes a blocking guide block 2033. A recovery component 204 is disposed below the blocking assembly 203, and the recovery component 204 has an open-top recovery chamber 2041 for recovering excess particulate material falling from the conveyor belt 2023. The recovery chamber 2041 is located below the discharge port 2011, and the conveyor belt 2023 passes over the recovery chamber 2041. The blocking guide block 2033 includes a guide block top wall 20331, guide block side walls 20332, and guide protrusions 20333. Two guide block side walls 20332 are provided, and the two guide block side walls 20332 are connected to opposite sides of the guide block top wall 20331. Along the bandwidth direction of the conveyor belt 2023, the two guide block side walls 20332 are located on opposite sides of the conveyor belt 2023. A guide cavity 20334 is formed on the inner surface 203321 of the guide block sidewall 20332 (the inner surface 203321 refers to the surface of the guide block sidewall 20332 near the conveyor belt 2023). The guide cavity 20334 communicates with the recycling cavity 2041, and the sidewall 203341 of the guide cavity 20334 is spaced apart from the conveyor belt 2023. That is, there is a certain distance between the sidewall 203341 of the guide cavity 20334 and the side of the conveyor belt 2023, rather than it being in contact with the side of the conveyor belt 2023. This creates a gap of a certain width through the guide cavity 20334, allowing excess particulate material to flow smoothly into the recycling cavity 2041 through the guide cavity 20334. This better avoids the blocking guide block 2033 squeezing excess particulate material during the recycling process, and better prevents the particulate material from being damaged.

[0101] The guide protrusion 20333 is connected to the inner surface of the top wall 20331 of the guide block and is located above the conveyor belt 2023 to block excess particulate material on the conveyor belt 2023 that is outside the receiving hole 2024. In other words, the guide protrusion 20333 specifically blocks and guides excess particulate material in the blocking guide block 2033. Two guide protrusions 20333 are provided, and the two guide protrusions 20333 are spaced apart to form a clearance groove 20335, which corresponds to the receiving hole 2024. When the conveyor belt 2023 is running, the particulate material located in the receiving hole 2024 on the conveyor belt 2023 can flow smoothly through the blocking guide block 2033 via the clearance groove 20335, while the particulate material at other positions on the outer surface of the conveyor belt 2023 will be blocked by the guide protrusions 20333 located on both sides of the clearance groove 20335, thereby ensuring that the particulate material conveyed backward is only located in the receiving hole 2024, realizing the quantitative conveying of materials.

[0102] Preferably, in one embodiment, along the conveying direction of the conveyor belt 2023, the outer surface 203331 of the guide protrusion 20333 extends obliquely away from the center of the conveyor belt 2023. That is, the outer surface 203331 of the guide protrusion 20333 is not parallel to the conveying direction of the conveyor belt 2023, but is inclined at a certain angle relative to the conveying direction of the conveyor belt 2023, and the inclination direction gradually moves away from the center of the conveyor belt 2023 (with the conveying direction of the conveyor belt 2023 as a reference). When the conveyor belt 2023 is running, particulate material located outside the receiving hole 2024 on the conveyor belt 2023 will be blocked and guided by the guide protrusion 20333. Then, guided by the conveyor belt 2023 and the outer surface 203331 of the guide protrusion 20333, the particulate material gradually approaches and flows into the guide cavity 20334, and finally, the particulate material is guided into the recycling cavity 2041. Specifically, the outer surface 203331 of the two guide bumps 20333 has an overall "eight" shaped structure.

[0103] Preferably, in one embodiment, the bottom of the recycling component 204 is provided with a discharge hole 2042, which communicates with the recycling chamber 2041. The particulate material conveying mechanism 200 further includes a connector 205 for connecting to an external recycling device. The connector 205 is connected to the recycling component 204 and communicates with the discharge hole 2042. When particulate material flows into the recycling chamber 2041, it can flow into the connector 205 through the discharge hole 2042, and then into the external recycling device through the connector 205, thereby achieving recycling. Specifically, the external recycling device may have a negative pressure structure, which can suck the particulate material in the connector 205 through negative pressure, thereby preventing the particulate material from accumulating in the recycling component 204 or the connector 205.

[0104] Preferably, in one embodiment, at least one of the sidewalls 20411 surrounding the recycling chamber 2041 is an inclined sidewall 204111, and the inclined sidewall 204111 is inclined toward the discharge hole 2042, thereby guiding the particulate material in the recycling chamber 2041 toward the discharge hole 2042 and preventing the particulate material from accumulating in the recycling chamber 2041.

[0105] Preferably, in one embodiment, the width of the top opening of the recycling chamber 2041 is not less than the bandwidth of the conveyor belt 2023, thereby allowing for smoother reception of excess particulate material flowing out from both sides of the conveyor belt 2023. When installing the recycling component 204, it can be aligned with the conveyor belt 2023 so that the central axis of the recycling component 204 and the central axis of the conveyor belt 2023 are on the same plane, thereby ensuring that all excess particulate material flowing out from both sides of the conveyor belt 2023 can flow into the recycling chamber 2041.

[0106] Preferably, in one embodiment, the conveyor belt assembly 202 further includes a negative pressure generating unit, which communicates with the receiving hole 2024 to provide negative pressure to the receiving hole 2024. By providing negative pressure to the receiving hole 2024 through the negative pressure generating unit, particulate material can be stably adsorbed within the receiving hole 2024 and move forward with the conveyor belt 2023. Specifically, when the conveyor belt assembly 202 is configured, grooves can be formed on the side plates on both sides of the conveyor belt 2023. These grooves can communicate with the receiving hole 2024, and the negative pressure generating unit can communicate with the grooves to provide negative pressure to the receiving hole 2024. The grooves can be positioned only between the discharge port 2011 and the discharge position of the conveyor belt 2023; the negative pressure is disconnected when the receiving hole 2024 moves to the discharge position. This allows the conveyor belt 2023 to transport particulate materials more stably, and also makes it easier for the adsorption port 21 to pick up the particulate materials.

[0107] Meanwhile, in one embodiment, a filter rod production device is also provided, which includes the granular material conveying device and the filter rod conveying line. The filter rod conveying line is located below the discharge position 102 and is used to receive the granular material delivered by the granular material conveying device 100.

[0108] The above description is merely an embodiment of the present invention. It should be noted that those skilled in the art can make improvements without departing from the inventive concept of the present invention, but these improvements all fall within the protection scope of the present invention.
