Description

Technical Field

[0001] This application relates to the field of aerosol generation technology, specifically to a tubular body collection device. Background Technology

[0002] Heated tobacco products are mainly divided into two categories: granular tobacco products and sheet-type or shredded tobacco products.

[0003] Pellet-type tobacco cartridges are made by mixing tobacco materials, smoke-generating agents, flavoring substances, etc., and forming them into granules of a certain size. Then, according to the designed structure of the tobacco cartridge, the granules are filled into pre-prepared paper tubes. After the entire tobacco cartridge is assembled, it becomes a complete heated tobacco cartridge.

[0004] Thin or filamentous tobacco cartridges can be assembled using a rolling method. The paper tube that wraps the tobacco cartridge is rolled up after the internal structure of the tobacco cartridge is completed, thus wrapping the internal structure of the tobacco cartridge.

[0005] The production of granular e-cigarette cartridges differs from that of sheet-type or shredded e-cigarette cartridges. Due to the characteristics of their material shape, granular e-cigarette cartridges are generally assembled by filling. The paper tubes used need to be pre-formed before the granules are filled into the paper tubes.

[0006] Paper tubes that have already been manufactured and defined are prone to disorder due to factors such as manufacturer packaging, transportation, and worker storage. Large-scale production lines cannot accommodate disordered paper tubes. To solve this problem, workers are usually trained to manually and orderly place multiple paper tubes into the mold. This method requires a large number of workers to perform mechanical labor, resulting in limited production efficiency and increased production costs for the company. Utility Model Content

[0007] This application provides a tubular body collection device, the main purpose of which is to improve the collection efficiency of tubular bodies.

[0008] One embodiment of this application provides a tubular body collection device, comprising:

[0009] The hopper has a discharge port on its side wall and is used to hold multiple tubular bodies to be processed.

[0010] The alignment and transmission component is connected to the discharge port;

[0012] A collection frame is suspended above the downstream end of the first conveyor belt assembly, and the end of the collection frame facing the first conveyor belt assembly has an inlet.

[0013] The alignment and transfer component is used to transfer the tubular body in the hopper to the first conveyor belt component in a predetermined placement direction. The first conveyor belt component is used to transfer the tubular body on it to the collection frame through the inlet. The conveying direction of the first conveyor belt component is perpendicular to the placement direction of the tubular body on the first conveyor belt component.

[0014] In one embodiment, the alignment and transfer assembly includes a second conveyor belt assembly, a swivel tray, and a conveyor tube;

[0015] The second conveyor belt assembly is fixed inside the hopper, and a portion of the second conveyor belt assembly passes through the discharge port and is positioned outside the hopper;

[0016] The slinger is located below the second conveyor belt assembly, and the side wall of the slinger has a discharge port;

[0017] The conveying pipe has an inlet and an outlet, and the inlet and the outlet are connected.

[0018] The first conveyor belt assembly is suspended below the outlet; the first conveyor belt assembly and the conveying pipe are spatially perpendicular;

[0019] The second conveyor belt assembly is used to transport the tubular body in the hopper to the sling plate. The sling plate is used to rotate so that the tubular body inside it moves to the side wall of the sling plate. The discharge port is used to allow the tubular body on the side wall of the sling plate to move out and enter the conveying pipe. The conveying pipe is used to transport multiple tubular bodies arranged in columns to the first conveyor belt assembly in sequence.

[0020] In one embodiment, the tubular body collecting device has a material inlet on the collecting frame in the material inflow direction near the first conveyor belt assembly, and a material blocking opening on the collecting frame in the material inflow direction away from the first conveyor belt assembly. The material inlet is larger than the diameter of the tubular body, and the material blocking opening is smaller than the diameter of the tubular body.

[0021] In one embodiment, the collecting frame is inclined relative to the first conveyor belt assembly to form the material passage and the material blocking opening between the collecting frame and the first conveyor belt assembly.

[0022] In one embodiment, a clamping member is further included, which is movably disposed within the collection frame and is capable of moving away from the first conveyor belt assembly as the number of tubular bodies in the collection frame increases. The clamping member is used to clamp the tubular bodies.

[0023] In one embodiment, an installation port is provided on the side plate of the collection frame and the first conveyor belt assembly that are parallel to the material feeding direction. The installation port is used to pick up and put in the clamping member in the collection frame.

[0024] In one embodiment, the slinging disc includes a disc bottom and a disc wall, the middle part of the disc bottom arches inward toward the slinging disc, and the discharge port is formed on the disc wall.

[0025] In one embodiment, the disk wall is fixed to the periphery of the disk bottom, and the disk wall and the disk bottom are spaced apart. The disk bottom is used to move the tubular body closer to the disk wall by rotation.

[0026] In one embodiment, the disc wall includes a first baffle and a second baffle; the first baffle surrounds to form the disc wall, and a first discharge port is formed between the two ends of the first baffle in the circumferential direction; the second baffle and the first baffle with the first discharge port are connected at intervals, and a second discharge port is formed between the second baffle and the first baffle, and the tubular body in the slinging disc enters the conveying pipe in sequence through the first discharge port and the second discharge port.

[0027] In one embodiment, the second baffle is an arc-shaped plate parallel to the first baffle, and the conveying pipe is connected to and tangent to the second discharge port;

[0028] And / or, the tubular body collecting device further includes an inclined discharge plate, which is fixed to one end of the second conveyor belt assembly near the swivel disc, with at least a portion of the discharge plate located directly above the swivel disc.

[0029] According to the tubular body collection device in the above embodiments, the tubular bodies in the hopper can be conveyed to the first conveyor belt assembly via the alignment and transfer component. The first conveyor belt assembly then conveys the tubular bodies through the inlet to the collection frame above it. In this way, the collection frame can collect the tubular bodies in an orderly manner via the first conveyor belt assembly, and multiple tubular bodies can be stacked from bottom to top within the collection frame for efficient collection. The conveying direction of the first conveyor belt assembly is perpendicular to the placement direction of the tubular bodies on it, allowing the tubular bodies to enter the collection frame in a specific direction. This facilitates orderly collection and makes full use of the space within the collection frame to collect more tubular bodies. Using the designed tubular body collection device, the entire process only requires feeding multiple randomly distributed tubular bodies into the hopper, which are then collected in an orderly manner by the collection frame. This effectively improves the tubular body collection efficiency, thereby increasing the processing efficiency of granular e-cigarette cartridges and reducing processing costs.

[0038] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments. Similar elements in different embodiments are referred to by related similar element reference numerals. In the following embodiments, many details are described to facilitate a better understanding of the present application. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by other elements, materials, or methods. In some cases, certain operations related to the present application are not shown or described in the specification. This is to avoid obscuring the core parts of the present application with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.

[0039] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments. At the same time, the steps or actions in the method description can be rearranged or adjusted in a manner obvious to those skilled in the art. Therefore, the various orders in the specification and drawings are only for the clear description of a particular embodiment and do not imply a necessary order, unless otherwise stated that a particular order must be followed.

[0040] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0041] Please see Figures 1-7 This application provides a tubular body collection device in one embodiment, applicable to the manufacture of heated tobacco cartridges. It is used to orderly collect multiple randomly distributed tubular bodies A (such as paper tubes or cylindrical heated tobacco cartridges) into a collection frame 60, thereby improving the processing efficiency of granular tobacco cartridges. The diameter of the tubular body A is generally 6.5-7.2 mm. The tubular body collection device includes: a hopper 20, an alignment and transfer assembly, a collection frame 60, and a first conveyor belt assembly 100.

[0042] The side wall of the silo 20 is provided with a discharge port 21. The silo 20 is used to place multiple tubular bodies A to be sorted.

[0043] The alignment and transmission components are connected to the discharge port 21.

[0044] The first conveyor belt assembly 100 is located downstream of the alignment and transmission assembly.

[0045] The collection frame 60 is suspended above the downstream of the first conveyor belt assembly 100, and the end of the collection frame 60 facing the first conveyor belt assembly 100 is provided with an inlet 60c.

[0046] The alignment and transfer component is used to transfer the tubular body A in the hopper 10 to the first conveyor belt assembly 100 in a predetermined placement direction. The first conveyor belt assembly 100 is used to transfer the tubular body A on it to the collection frame 60 through the inlet 60c. The conveying direction of the first conveyor belt assembly 100 is perpendicular to the placement direction of the tubular body A on the first conveyor belt assembly 100.

[0047] It is understandable that the upstream and downstream of the alignment transmission component refer to the two ends along the transmission direction, that is, the transmission direction of the alignment transmission component is from upstream to downstream. The upstream and downstream of the first conveyor belt assembly refer to the two ends along the transmission direction, that is, the transmission direction of the first conveyor belt assembly is from upstream to downstream.

[0048] Using the tubular body collection device in the above embodiment, the tubular body A in the hopper 20 can be conveyed to the first conveyor belt assembly 100 via the alignment and transfer component. The first conveyor belt assembly 100 then conveys the tubular body A through the inlet 60c to the collection frame 60 above it. Thus, the collection frame 60 can collect the tubular body A in an orderly manner via the first conveyor belt assembly 100. Furthermore, multiple tubular bodies A can be stacked from bottom to top within the collection frame 60 to facilitate orderly collection. The conveying direction of the first conveyor belt assembly 100 is perpendicular to the placement direction of the tubular body A on the first conveyor belt assembly 100. This allows the tubular body A to enter the collection frame 60 in a specific direction, facilitating orderly collection and making full use of the space within the collection frame 60 to collect more tubular bodies A. Using the designed tubular body collection device, the entire process only requires putting multiple randomly distributed tubular bodies A into the hopper 20, and then collecting multiple tubular bodies A in an orderly manner through the collection frame 60, which effectively improves the collection efficiency of tubular bodies A, thereby improving the processing efficiency of granular e-cigarette cartridges and reducing processing costs.

[0049] The tubular body collection device also includes a stage 10, and the alignment and transfer components include a second conveyor belt assembly 30, a swivel disc 40, and a transfer pipe 50.

[0050] The stage 10 has a loading surface 11, for example, Figure 1 As shown, the stage 10 is a rectangular block, and a loading surface 11 is formed on the top surface of the stage 10.

[0051] The hopper 20 is fixed to the loading surface 11. A feeding port is opened on the hopper 20. Multiple messy tubular bodies A are put into the hopper 20 through the feeding port. In order to make full use of the space, the top of the hopper 20 is open. The opening at the top is used as a feeding port to facilitate the feeding of tubular bodies A into the hopper 20.

[0052] The second conveyor belt assembly 30 is fixed inside the hopper 20, and a portion of the second conveyor belt assembly 30 passes through the discharge port 21 and is placed outside the hopper 20.

[0053] The slinger 40 is located below the second conveyor belt assembly 30 and is fixed to the loading surface 11. The side wall of the slinger 40 has a discharge port.

[0054] The conveying pipe 50 has an inlet 51 and an outlet 52, and the inlet 51 and the outlet are connected.

[0055] The first conveyor belt assembly 100 is suspended below the outlet 52, and the first conveyor belt assembly 100 and the conveying pipe 50 are spatially perpendicular.

[0056] The slinger 40 is located between the load surface 11 and the second conveyor belt assembly 30, along a direction perpendicular to the load surface 11. The second conveyor belt assembly 30 is used to transport the tubular body A from the hopper 20 to the slinger 40. The slinger 40 is used to rotate, causing the tubular body A within it to move to the side wall of the slinger 40 through centrifugal motion, and adjusting the tubular body to a horizontal position. The discharge port is used for the tubular body A to be removed from the side wall of the slinger 40 to enter the conveying pipe 50, and the conveying pipe 50 is used to transport multiple tubular bodies A arranged in rows sequentially to the first conveyor belt assembly 100 through the outlet 52.

[0057] The tubular body collecting device has a feed inlet 60a on the collecting frame 60 near the first conveyor belt assembly 100 in the material inflow direction, and a blocking inlet 60b on the collecting frame 60 away from the first conveyor belt assembly 100 in the material inflow direction. The feed inlet 60a is larger than the diameter of the tubular body A, and the blocking inlet 60b is smaller than the diameter of the tubular body A. In this way, the tubular body A on the first conveyor belt assembly 100 can enter the collecting frame 60 through the feed inlet 60a, and the blocking inlet 60b can ensure that all the tubular bodies A on the first conveyor belt assembly 100 can be collected by the collecting frame 60.

[0058] In some embodiments, the collection frame 60 is inclined relative to the first conveyor belt assembly 100 to form a material passage 60a and a material blocking passage 60b between the collection frame 60 and the first conveyor belt assembly 100.

[0059] Please see Figures 4-5 More preferably, in some embodiments, the tubular body collecting device further includes a clamping member 110 movably placed within the collecting frame 60, the clamping member 110 being movable toward the side away from the first conveyor belt assembly 100 as the number of tubular bodies A in the collecting frame 60 increases, the clamping member 110 being used to clamp the tubular bodies A.

[0060] The clamping component 110 can be in the form of a plate, grid, or block with a certain weight. For example, the clamping component 110 can be an acrylic plate. Acrylic material is relatively light overall and also has a certain structural strength. The collection frame 60 can also be made of acrylic material.

[0061] Please see Figures 4-5 When collecting tubular bodies A in the collection frame 60, as the number of tubular bodies A in the collection frame 60 increases or rises, the clamping member 110 is also pushed and gradually rises. Through the clamping member 110, multiple tubular bodies A collected in the collection frame 60 can be pressed down, causing multiple tubular bodies A in the collection frame 60 to be arranged neatly.

[0062] The collection frame 60 is provided with an installation port 60d, which is used to retrieve and place the clamping member 110 inside the collection frame 60. Specifically, for example... Figure 6 As shown, the collecting frame 60 is a rectangular frame formed by four panels. The bottom surface of the collecting frame 60 is an open inlet 60c. An open mounting port 60d is provided on the side plate of the collecting frame 60 and the first conveyor belt assembly 100, which are parallel to the material inlet direction. Or, for example, Figure 7 As shown, the collection frame 60 is also a rectangular frame formed by four panels, but unlike the previous frame, this frame includes four side panels and an open mounting opening 60d at the top. Multiple ribs are fixed at the top to act as the frame base and support the tubular body A inside. When the collection frame 60 is almost full of tubular bodies A, the clamping member 110 is pushed to the top of the collection frame 60 or to one end away from the second conveyor belt 103. At this point, the collection of one frame of tubular bodies A can be considered complete, and the tubular body collection device can be stopped. The collection frame 60 can be restarted after a new one is replaced.

[0063] Please see Figures 4-5 The tubular collecting device also includes a first support leg 120 and a second support leg 130. The first support leg 120 is used to support and fix the first conveyor belt assembly 100, and the second support leg 130 is used to support the collecting frame 60. The second support leg 130 may be higher than the second conveyor belt 103, and the second support leg 130 at different positions has different heights so as to form a material passage 60a and a material blocking passage 60b between the collecting frame 60 and the second conveyor belt 103.

[0064] Correspondingly, the height of the second support leg 130 on the side of the feed inlet 60a is higher than the height of the second support leg 130 at the feed stop 60b. The different heights of the second support legs 130 also allow the clamping members 110 to initially be distributed at an angle within the collection frame 60, so that after the tubular body A enters the collection frame 60, it can push the clamping members 110 upwards along the height direction or perpendicular to the second conveyor belt 103. It should be noted that "initially" refers to the situation when there is no tubular body A in the collection frame 60.

[0065] Please see Figures 1-2 In some embodiments, the sling plate 40 includes a plate bottom 41 and a plate wall 42. A discharge port is provided on the plate wall 42. The middle part of the plate bottom 41 arches inward toward the sling plate 40. In this way, the multiple tubular bodies A fed into the sling plate 40 can be guided by the arched surface on the plate bottom 41, which facilitates the movement of the tubular bodies A toward the plate wall 42. Combined with the rotation of the sling plate 40, the movement of the tubular bodies A toward the tube wall can be achieved more quickly.

[0066] Please see Figure 1 The tubular body collecting device also includes a second driving member 90, which is fixed to the carrying surface 11. The second driving member 90 is, for example, a motor. The power shaft of the second driving member 90 is fixedly connected to the bottom of the tray 41, and the second driving member 90 is used to synchronously drive the bottom of the tray 41 to rotate via the power shaft. A tray wall 42 is fixed to the periphery of the bottom of the tray 41, with the tray wall 42 and the bottom of the tray 41 spaced apart. The bottom of the tray 41 is used to move the tubular body A closer to the tray wall 42 by rotation. For example, the tray wall 42 is fixed to the carrying surface 11 on the periphery of the bottom of the tray 41 by multiple circumferentially spaced supports, or the tray wall 42 is fixed to the side wall of the hopper 20 on the periphery of the bottom of the tray 41. With the disc wall 42 acting as a barrier to the tubular body A inside the throwing disc 40, the separation of the disc wall 42 and the disc bottom 41 can, on the one hand, prevent friction between the two from hindering the rotation of the disc bottom 41, and on the other hand, reduce the weight of the rotating part in the throwing disc 40, which is beneficial to reducing the power consumption of the second drive component 90 and the tubular body collection device.

[0067] Even better, to further reduce the power consumption of the second drive unit 90, the base 41 is a cone or cone ring formed by a plate structure. The plate structure can effectively reduce the weight of the base 41 compared to the block structure, thereby reducing the power consumption of the second drive unit 90.

[0068] Please see Figures 1-2 The disc wall 42 includes a first baffle 421 and a second baffle 422. The first baffle 421 surrounds and forms the disc wall 42, and a first discharge port 421a is formed between the two ends of the first baffle 421 in the circumferential direction. The second baffle 422 is located outside the first baffle 421, and the second baffle 422 and the first baffle 421 with the first discharge port 421a are connected at intervals, and a second discharge port 422a is formed between the second baffle 422 and the first baffle 421. The tubular body A in the slinger 40 enters the conveying pipe 50 through the first discharge port 421a and the second discharge port 422a in sequence.

[0069] The second baffle 422 has a base plate at one end near the loading surface 11. The base plate supports the tubular body A that moves out of the first discharge port 421a, preventing the tubular body A from falling down. The arc length of the first discharge port 421a is slightly greater than the axial length of the tubular body A, ensuring that one tubular body A comes out of the first discharge port 421a at a time. The width of the second discharge port 422a is slightly greater than the diameter of the tubular body A, ensuring that only one tubular body A passes through and enters the conveying pipe 50 at a time. Similarly, to ensure the orderly arrangement of the tubular bodies A inside the conveying pipe 50, the width of the conveying pipe 50 is slightly greater than the diameter of the tubular bodies A. For example, the width of the conveying pipe 50 is 1.05-1.2 times the diameter of the tubular body A.

[0070] It is understandable that the direction corresponding to the width of the second discharge port 422a and the direction corresponding to the width of the conveying pipe 50 both refer to the direction perpendicular to the length direction of the conveying pipe 50. The first discharge port 421a and the second discharge port 422a mentioned above correspond to the discharge ports mentioned above.

[0071] The tubular body A exits from the first outlet 421a formed by the first baffle 421 and undergoes centrifugal motion. During this process, the orientation of the tubular body A may change. The second baffle 422 outside the first outlet 421a can intercept and correct the changed orientation of the tubular body A after it exits. The tubular body A moves to the second outlet 422a through the channel formed between the first baffle 421 and the second baffle 422. The second outlet 422a facilitates docking with the inlet 51 of the conveying pipe 50, thereby facilitating the movement of the tubular body A into the conveying pipe 50.

[0072] More preferably, the second baffle 422 is an arc-shaped plate parallel to the first baffle 421, and the conveying pipe 50 is connected to and tangent to the second discharge port 422a. The arc-shaped plate makes the direction of movement of the tubular body A parallel to the tangent direction of the arc-shaped plate, and the connection and tangency of the conveying pipe 50 and the second discharge port 422a facilitates the entry of the tubular body A into the conveying pipe 50 while avoiding a reduction in the kinetic energy of the tubular body A. This allows the tubular body A to continue moving linearly within the conveying pipe 50 using the velocity gained in the swivel disc 40, and then sequentially enter the collection frame 60.

[0073] More preferably, the sling plate 40 also includes a guide plate 424, which is fixed between the first baffle 421 and the second baffle 422 near the second discharge port 422a. The guide plate 424 is used to guide and regulate the position of the tubular body A that moves to the second discharge port 422a, so that the axial direction of the tubular body A is parallel to the length direction of the conveying pipe 50.

[0074] Please see Figure 3The guide plate 424 is mainly divided into two sections. The first section is close to the first discharge port 421a, and the second section is close to the second discharge port 422a. The guide plate 424 in the first section forms a flared mouth between the first discharge port 421a and the second discharge port 422a, so that the tubular body A can enter the channel formed between the first baffle 421 and the second baffle 422. The guide plate 424 in the second section is parallel to the second baffle 422 or the first baffle 421, so as to maintain the direction of movement of the tubular body A. Figure 3 The middle arrow indicates the direction of rotation of the swivel disc 40. This direction of rotation is mainly determined by the position of the conveying pipe 50. Similarly... Figure 2 The arrow in the image also indicates the direction of rotation of the 40-degree turntable.

[0075] Please see Figure 1 In some embodiments, the bottom of the hopper 20 is a rectangular frame, and the top is a conical frame. A discharge port 21 is opened on the side wall of the conical frame facing the slinger 40. The rectangular frame can raise the height of the conical frame, facilitating the conveying of the tubular material A from the hopper 20 into the slinger 40. A second conveyor belt assembly 30 is disposed within the hopper 20. The second conveyor belt assembly 30 includes two spaced-apart first conveyor wheels 31 and 32, and a first conveyor belt 33. The first conveyor wheels 31 are fixed inside the hopper 20, and the second conveyor wheels 32 are fixed outside the hopper 20. The first conveyor belt 33 is sleeved on the outside of the first and second conveyor wheels 31 and 32. The second conveyor belt assembly 30 is equipped with a first drive member (not shown). At least one of the first and second conveyor wheels 31 and 32 can be connected to the first drive member to obtain rotational power.

[0076] Even better, a structure for controlling the size of the discharge port can be added at the discharge port to control the amount of tubular body A fed into the slinger 40. For example, a slot can be provided on the side wall of the hopper 20 at the discharge port, and the size of the exposed discharge port can be adjusted by inserting the plate and the slot.

[0077] Preferably, an inclined discharge plate 70 is fixed at the second conveyor wheel 32. The discharge plate 70 can be fixed to the hopper 20 or the axle of the second conveyor wheel 32, as long as the discharge plate 70 can be fixed, there are no specific restrictions. At least part of the discharge plate 70 is located directly above the slinger 40, and the discharge plate 70 can play a guiding and buffering role.

[0078] In other embodiments, if the space between the second conveyor belt assembly 30 and the slinger 40 is insufficient, the height of the second conveyor belt assembly 30 or the hopper 20 can be increased by setting a heightening seat 80. In this case, the two ends of the heightening seat 80 are connected to the platform 10 and the hopper 20, respectively.

[0079] Specifically, the first conveyor belt assembly 100 includes a first drive wheel 101, a second drive wheel 102, and a second conveyor belt 103. The first drive wheel 101 and the second drive wheel 102 are spaced apart, and the second conveyor belt 103 is tightly fitted to the outside of the first drive wheel 101 and the second drive wheel 102. The tubular body collecting device also includes a third driving member, which is connected to either the first drive wheel 101 or the second drive wheel 102. The third driving member drives the first conveyor belt assembly 100 to rotate as a whole, thereby conveying the tubular body A near the conveying pipe 50 to the collecting frame 60.

[0080] Baffles (not shown) are provided on both sides of the second conveyor belt 103 to prevent the tubular body A on the second conveyor belt 103 from falling off. The baffles on both sides are mainly divided into front and rear sections. The front section is located on the side closer to the conveying pipe 50, and the rear section is located on the side closer to the collection frame 60. To ensure the correct orientation of the tubular body A on the conveying pipe 50 when it falls onto the second conveyor belt 103, the baffles on both sides at the front section form a funnel-shaped space. The width of the space at the baffles on both sides gradually decreases from the side away from the collection frame 60 to the side closer to the collection frame 60.

[0081] The baffles on both sides at the tail section are parallel, and the width of the space at this point is the same as the width of the second conveyor belt 103, for example, both being 1-1.1 times the length of the tubular body A.

[0082] The feed inlet 60a is designed to allow the tubular body A to move to the feed inlet 60c and enter the collection box 60. The interceptor 60b is designed to intercept the tubular body A and prevent it from passing through the interceptor 60b, thus avoiding ineffective collection. Based on this, along the direction perpendicular to the second conveyor belt 103, the size of the feed inlet 60a is greater than one time the diameter of the tubular body A but less than twice the diameter of the tubular body A. For example, the size of the feed inlet 60a is 1.2-1.5 times the diameter of the tubular body A. The size of the interceptor 60b is less than the diameter of the tubular body A. For example, the size of the interceptor 60b is 0.3-0.6 times the diameter of the tubular body A.

[0083] Even better, the conveying pipe 50 and the second conveyor belt 103 are inclined, so that the movement speed of the tubular body A inside the conveying pipe 50 and the second conveyor belt 103 can be improved or guaranteed.

[0084] In other embodiments, the conveying pipe 50 and the second conveyor belt 103 can also be horizontally distributed. When the conveying pipe 50 is horizontally distributed, the tubular body A inside it moves within the conveying pipe 50 at the speed at the second discharge port 422a. When the tubular body A moves to the outlet 52 of the conveying pipe 50, it can still have a certain speed and move horizontally onto the second conveyor belt 103 at this speed. At this time, the second conveyor belt 103 and the outlet 52 of the conveying pipe 50 are spatially staggered. Alternatively, the speed of the tubular body A becomes zero in the conveying pipe 50 due to friction. It can be pushed by the tubular body A that enters the previous or previous one of the conveying pipe 50. When the tubular body A moves to the outlet 52, it can fall freely onto the second conveyor belt 103. At this time, the second conveyor belt 103 and the outlet 52 of the conveying pipe 50 can be spatially opposite each other.

[0085] In other embodiments, the conveying pipe 50 may also adopt a structural design of the first conveyor belt assembly 100 and the baffles on both sides of the second conveyor belt 103 to form a conveying pipeline.

[0086] Please see Figure 1 and Figure 5 More preferably, the tubular body collecting device also includes a pressure detection element 140, a first material detection element 150, a second material detection element 160, and a controller (not shown). The first drive element corresponding to the second conveyor belt assembly 30, the second drive element 90 corresponding to the first conveyor belt assembly 100, the pressure detection element 140, the first material detection element 150, and the second material detection element 160 are all electrically connected to the controller.

[0087] The pressure detection element 140 is fixed to the end face of the second support leg 130 facing the collection frame 60. The pressure detection element 140 is used to start or stop the tubular body collection device based on the detected pressure signal. For example, when the collection frame 60 is placed on the second support leg 130, the pressure signal detected by the pressure detection element 140 is 1. After the pressure detection element 140 sends this pressure signal to the controller, the controller will start the first drive element and the second drive element 90. When the collection frame 60 is not placed on the second support leg 130, the pressure signal detected by the pressure detection element 140 is 0. After the pressure detection element 140 sends this pressure signal to the controller, the controller will shut down the first drive element and the second drive element 90. The pressure detection element 140 is, for example, a pressure sensor.

[0088] The first material detection element 150 is fixed inside the collection frame 60 at one end away from the second conveyor belt 103. The first material detection element 150 is used to control the working state of the tubular body collection device based on the detection of a tubular body A or a clamping element 110 at the same height inside the collection frame 60. For example, when the first material detection element 150 detects a tubular body A or a clamping element 110 at that location, the first material detection element 150 sends this information to the controller. The controller will then shut down the first drive element and the second drive element 90 based on the feedback from the first material detection element 150 to replace the collection frame 60.

[0089] The second material detection element 160 is fixed to the inner wall of the sling plate 40. The second material detection element 160 is used to control the working state of the tubular body collection device based on the detection of a tubular body A at the same height as the second material detection element 160 (i.e., the material content of the tubular body A in the sling plate 40). For example, when the second material detection element 160 detects a tubular body A at that location, it sends this information to the controller. The controller will shut down the first drive element based on the feedback from the second material detection element 160. At this time, there is friction between the tubular body A and the first conveyor belt 33, and the tubular body A will not continue to fall into the sling plate 40.

[0090] Correspondingly, a second material detection element 160 is also fixed to the inner wall of the sling plate 40 near the loading surface 11. The second material detection element 160 is used to control the working state of the tubular body collection device based on the detected tubular body A at the same height. For example, when the second material detection element 160 near the loading surface 11 does not detect the tubular body A, it sends this information to the controller. The controller can activate the first drive element based on the information fed back by the second material detection element 160 near the loading surface 11 to avoid insufficient material supply in the sling plate 40.

[0091] Among them, the first material detection element 150 and the second material detection element 160 are both infrared sensors, for example.

[0092] The tubular body collection device includes the pressure detection element 140, the first material detection element 150, the second material detection element 160, and the controller mentioned in the above embodiments, which facilitates the automated control of the tubular body collection device and can further improve the collection efficiency of tubular body A.

[0093] The tubular body collecting device in the above embodiments designed in this application can collect multiple tubular bodies A in an orderly manner into the collecting frame 60, which facilitates the tubular bodies A to smoothly enter the production line of granular tobacco cartridges for large-scale production, greatly improving production efficiency and reducing labor and production costs.

[0094] The above examples illustrate this application only to aid understanding and are not intended to limit its scope. Those skilled in the art to which this application pertains can make various simple deductions, modifications, or substitutions based on the ideas presented.
