After production by the extrusion setting mechanism, the profile successively passes through the cooling mechanism, the cutting mechanism and the traction mechanism. The cutting mechanism can reciprocate linearly between the cooling mechanism and the traction mechanism. The traction mechanism is used for synchronous centering and traction transportation of the profile passing through the cutting mechanism. The cutting mechanism cuts the profile passing through the traction mechanism to obtain a target profile. The movement speed of the cutting mechanism is equal to the traction speed of the profile by the traction mechanism, so that the cutting mechanism and the profile are in a relatively static state, thereby solving the problem that the traction mechanism cannot automatically and accurately center the upper and lower conveying rollers relative to the center of the production line when adjusting the pipe diameter specification, and the problem that the thin-walled pipe is crushed and deformed due to rigid contact clamping.

Description

Technical Field

[0001] This patent relates to the field of cigarette manufacturing technology, specifically to a production apparatus for aerosol-generated product profiles. Background Technology

[0002] With the increasing popularity of new heated tobacco products in the market, the structure of the cooling section, as a core component, is also constantly iterating. Currently, polylactic acid (PLA) has become the mainstream material for manufacturing cooling sections due to its good biodegradability and processing performance. However, the existing PLA uses film folding technology, which involves first making PLA into a film and then performing complex folding and rolling. This method is not only lengthy, but also requires extremely high precision from biaxial stretching equipment, resulting in high production costs.

[0003] To address the issues of complex film processing and insufficient safety and cooling performance in paper tube composite processes, direct extrusion molding of PLA cooling tubes has emerged. This technology eliminates the need for adhesives and allows for the maximization of flue gas contact area through complex cross-sectional shapes. However, PLA material exhibits physical characteristics such as thin walls, slow cooling and crystallization, and brittleness after molten processing. This places high demands on the automation and precision of production equipment. The production line must encompass the entire process of raw material extrusion, shaping, cooling, traction, and cutting. The stability of coordination between these processes, especially the smoothness of the traction stage, directly determines the uniformity of the final tube wall thickness and its straightness.

[0004] Existing equipment for producing cooling pipes typically uses an upper and lower conveyor roller clamping mechanism to move the pipes through friction. Early traction equipment often used rollers with a fixed spacing, which could not adapt to pipes of different specifications.

[0005] To address the aforementioned issues, existing technologies have introduced adjustable-gap pressure roller mechanisms. Typically, the upper pressure roller is raised and lowered by manually rotating a lead screw to accommodate changes in pipe diameter. However, existing adjustment methods are mostly rigid mechanical locking, meaning that once the lead screw is locked, there is hard contact between the conveying roller and the pipe. For thin-walled and fragile PLA cooling pipes, this inelastic rigid clamping is extremely difficult to control. Even slight errors can flatten and deform the pipe or cause surface damage. Furthermore, existing equipment often requires two separate handwheels for height adjustment of the upper and lower conveying rollers, or only the upper roller can be adjusted while the lower roller remains fixed. This makes it difficult to ensure that the upper and lower rollers open and close at equal intervals relative to the production line center when changing to different pipe diameters. This results in the traction center line not coinciding with the extrusion center line, leading to uneven stress on the pipe and causing bending.

[0006] Therefore, there is an urgent need for a production device for aerosol-generated product profiles with an improved structure that can effectively solve the above problems. Summary of the Invention

[0007] This patent aims to solve the problems of existing profile production equipment's traction mechanism, which struggles to ensure accurate and automatic alignment of the upper and lower conveyor rollers relative to the production line center when adjusting pipe diameter specifications, and the use of rigid contact clamping leading to the flattening and deformation of thin-walled pipes. This patent provides the following technical solution: In a first aspect, a production apparatus for aerosol-generated profiles is provided, comprising: an extrusion shaping mechanism; a cooling mechanism; a cutting mechanism; and a traction mechanism. The cutting mechanism is disposed between the cooling mechanism and the traction mechanism, and the extrusion shaping mechanism is disposed at the starting end of the production apparatus. After being produced by the extrusion shaping mechanism, the profile sequentially passes through the cooling mechanism, the cutting mechanism, and the traction mechanism, and finally, the target profile is obtained under the action of the cooling mechanism, the cutting mechanism, and the traction mechanism. The cutting mechanism is capable of reciprocating linear motion between the cooling mechanism and the traction mechanism. The traction mechanism is used to synchronously center and traction transport the profile passing through the cutting mechanism. The cutting mechanism cuts the profile passing through the traction mechanism to obtain the target profile. The movement speed of the cutting mechanism is equal to the traction speed of the traction mechanism on the profile, so that the cutting mechanism and the profile are in a relatively stationary state.

[0008] Furthermore, the traction mechanism includes a traction frame, a synchronous moving component, a rotating component, a first roller assembly, and a second roller assembly. The first roller assembly and the second roller assembly are symmetrically arranged within the traction frame, and the section between the first roller assembly and the second roller assembly is used for passing through the profile. The synchronous moving component is fixedly connected to the first roller assembly and the second roller assembly respectively. The rotating component is connected to one end of the synchronous moving component and acts directly on the synchronous moving component. The synchronous moving component is a bidirectional component that applies a rotational force to the rotating component. Under the action of the rotational force, the synchronous moving component drives the first roller assembly and the second roller assembly to move synchronously in a straight line towards the axis of symmetry, so that the traction mechanism synchronously centers the profile, thereby placing the clamping center of the profile on the center line of the production device.

[0009] Furthermore, the traction mechanism also includes a traction motor, which drives the first roller assembly to run and, under the action of the first roller assembly, pulls the profile for traction and transportation; the first roller assembly and the second roller assembly are equipped with airbag damping cylinders to provide flexible cushioning to the profile.

[0010] Furthermore, the cutting mechanism includes a linear motor, a slide table, a first ring, and a second ring. The second ring is fitted inside the first ring and can rotate relative to the first ring. The first ring is fixed on the slide table, which is mounted on the linear motor and causes the first ring to reciprocate linearly under the action of the linear motor.

[0011] Furthermore, the inner ring of the second ring is smooth while the outer ring is provided with cutting grooves, and the first ring is provided with a through groove, so that the cutting grooves are exposed to the external environment when passing through the through groove; the cutting mechanism also includes a rotary cutting component and a fixed-point cutting component. The rotary cutting component acts on the cutting grooves at the through groove, so that the second ring rotates relative to the first ring under the action of gear meshing, thereby performing rotary cutting on the profile; the rotary cutting component includes a rotary cutting gear and a rotary cutting motor. The rotary cutting motor drives the rotary cutting gear to rotate, and the rotary cutting gear meshes with the cutting grooves at the through groove.

[0012] Furthermore, the fixed-point cutting component is set inside the second ring. The fixed-point cutting component moves linearly within the second ring to perform fixed-point cutting on the profile. The fixed-point cutting component includes a telescopic rod, a guide rod, a tray, a fixed-point cutting motor, and a fixed-point cutting cutter head. The fixed-point cutting motor and the fixed-point cutting cutter head are set on the tray, and the fixed-point cutting motor is used to drive the fixed-point cutting cutter head. The guide rod is set inside the second ring, and the telescopic rod is set at one end of the tray so that the telescopic rod drives the tray to move along the guide rod to perform fixed-point cutting on the profile.

[0013] Furthermore, the cooling mechanism includes a first pipe, a second pipe, and a cooling transport assembly. The second pipe is movably fitted inside the first pipe, and the cooling transport assembly acts on the second pipe to cause the second pipe to rotate relative to the first pipe. The first pipe has a window, and the second pipe has a cooling tooth groove. The window exposes the outer surface of the second pipe, and the cooling tooth groove is set on the second pipe inside the window. The cooling transport assembly includes a cooling rotating gear and a cooling motor. The cooling rotating gear meshes with the cooling tooth groove, causing the cooling motor to drive the cooling rotating gear to rotate the second pipe.

[0014] Furthermore, a cooling sealed cavity for containing cooling liquid is formed between the first pipe and the second pipe. The first pipe is provided with an inlet and an outlet, and the second pipe is provided with a spray head. The cooling liquid enters the cooling sealed cavity from the inlet and exits from the outlet. Part of the cooling liquid in the cooling sealed cavity is sprayed onto the profile in the second pipe through the spray head to cool and solidify it.

[0015] Furthermore, the production unit also includes a control mechanism, which is electrically connected to the telescopic rod, the rotary cutting motor, the traction motor, and the fixed-point infeed motor.

[0016] Furthermore, the production apparatus also includes a worktable for housing the extrusion shaping mechanism, cooling mechanism, cutting mechanism, and traction mechanism; the cooling and transport assembly also includes a support plate for connecting the worktable and the cooling rotary gear; the profile is one of tubular profile, strip profile, or column profile.

[0017] This patent has the following beneficial effects: 1. A production apparatus for aerosol-generated profiles is provided, comprising an extrusion and shaping mechanism, a cooling mechanism, a cutting mechanism, a traction mechanism, a worktable, and a control mechanism. After being produced by the extrusion and shaping mechanism, the profile sequentially passes through the cooling mechanism, the cutting mechanism, and the traction mechanism. The cutting mechanism is capable of reciprocating linear motion between the cooling mechanism and the traction mechanism. The traction mechanism is used to synchronously center and traction transport the profile passing through the cutting mechanism. The cutting mechanism cuts the profile passing through the traction mechanism to obtain the target profile. The movement speed of the cutting mechanism is equal to the traction speed of the traction mechanism on the profile, so that the cutting mechanism and the profile are in a relatively static state. This solves the problem that the traction mechanism is difficult to ensure automatic and accurate centering of the upper and lower conveying rollers relative to the center of the production line when adjusting the pipe diameter, and that the use of rigid contact clamping causes the thin-walled pipe to be flattened and deformed.

[0018] 2. In this patent, the rotating handle drives the two bidirectional lead screws on both sides to rotate synchronously. Utilizing the opposite rotation direction of the upper and lower threads of the bidirectional lead screws, the upper and lower traction beams and conveying rollers are driven to move synchronously in opposite directions or in opposite directions. This mechanically ensures that the traction center always coincides with the center of the production line when adjusting the pipe diameter. Furthermore, the pneumatic damping cylinder pushes the movable plate, allowing the conveying rollers to use an elastically floating clamping force to adapt to minor errors on the pipe surface. This effectively prevents the flattening and deformation of thin-walled cooling pipes caused by rigid mechanical clamping, thereby improving the yield rate.

[0019] 3. In this patent, a linear motor drives the slide to move at the same speed as the pipe traction speed, keeping the cutting component and the pipe relatively stationary, thus avoiding pulling during cutting. Combined with the rotary cutting motor driving the second ring to drive the fixed-point cutting head to revolve around the pipe and the fixed-point cutting head itself to rotate at high speed, it can cut along the circumference of the pipe, which not only ensures the perpendicularity and flatness of the cut surface, but also enables the production line to run continuously without interruption, thus improving processing efficiency.

[0020] 4. In this patent, the second pipe is driven by a cooling motor to rotate continuously inside the first pipe, which drives the spray head installed on the second pipe to make a 360-degree circular motion around the cooling pipe and spray cooling water. This eliminates the uneven heating of the pipe caused by traditional static immersion or one-sided spraying. By actively destroying the thermal boundary layer on the surface of the pipe, the uniformity of the cooling and shrinkage rate around the pipe is ensured, effectively preventing the bending deformation of the cooling pipe caused by uneven cooling.

[0028] To make the objectives, technical solutions, and advantages of this patent clearer, the embodiments of this patent will be described in further detail below with reference to the accompanying drawings.

[0029] The present invention provides a production apparatus for aerosol-generated product profiles, which aims to solve the problems existing in the prior art, such as difficulty in traction and alignment of thin-walled pipes during production, easy flattening and deformation, need to stop the machine during cutting, uneven cuts, and bending deformation caused by uneven cooling.

[0030] Please refer to Figures 1-2 The production device mainly includes: an extrusion and shaping mechanism 200 for plasticizing raw materials and initially shaping them into profiles 700; a cooling mechanism 300 for rapidly and uniformly cooling and solidifying the shaped profiles 700; a cutting mechanism 400 for precisely cutting the cooled profiles 700 to a set length; a traction mechanism 500 for continuously advancing the profiles 700 and ensuring stable alignment during the traction process; and a control mechanism 600 for coordinating and controlling the action sequence and motion parameters of the above mechanisms.

[0031] All core functional components of the entire production unit are integrated and installed on a common workbench 100. The workbench 100 is a high-rigidity welded structural component that has been precision machined. The top surface of the workbench 100 has a uniform mounting reference plane, which provides a precise positioning base for the extrusion shaping mechanism 200, cooling mechanism 300, cutting mechanism 400 and traction mechanism 500, ensuring the consistency of the centerline height of the entire production line from the extrusion end to the traction end.

[0032] First, the specific composition, assembly relationship and positional layout of the traction mechanism 500 and other mechanisms are explained in detail. The traction mechanism 500 is set at the top right end of the workbench 100, which is the very end of the entire production device.

[0033] After being cooled, cured, and cut, the profile 700 is finally delivered by the traction mechanism 500, which provides continuous forward traction.

[0034] Please refer to Figures 3-4 The core supporting component of the traction mechanism 500 is a traction frame 510, which adopts a gantry structure design and has extremely high structural rigidity. The traction frame 510 is firmly fixed to the top right end plane of the workbench 100 by multiple sets of high-strength bolts. The interior of the traction frame 510 forms a hollow traction inner frame 512 for accommodating other traction components.

[0035] Inside the traction frame 510, there is a lead screw receiving cavity 511. Within the lead screw receiving cavity 511, along the conveying direction of the profile 700, i.e., on both the front and rear sides of the worktable 100, synchronous moving components 520 are provided. Each component has a high-precision bidirectional lead screw, namely a first bidirectional lead screw 521 and a second bidirectional lead screw 522, which are vertically arranged and threadedly connected. The axes of these two bidirectional lead screws are parallel to each other and perpendicular to the table surface of the worktable 100.

[0036] Each double-acting lead screw has two sections of threads with opposite directions machined on its outer wall; the upper section is a right-hand thread, and the lower section is a left-hand thread. A first traction beam 545 and a second traction beam 555 are respectively connected to the upper and lower sides of the outer walls of the first double-acting lead screw 521 and the second double-acting lead screw 522 via threaded pairs.

[0037] The first traction beam 545 is located at the top and is threadedly connected to the upper section of the bidirectional lead screw; the second traction beam 555 is located at the bottom and is threadedly connected to the lower section of the bidirectional lead screw.

[0038] When the bidirectional lead screw rotates, since the upper and lower threads rotate in opposite directions, the first traction beam 545 and the second traction beam 555 will move synchronously and in opposite directions along the lead screw axis, that is, they will move closer to each other or move further apart.

[0039] To ensure the stability and directional accuracy of the first traction beam 545 and the second traction beam 555 during movement, their outer portions form a sliding connection structure with the inner wall of the traction frame 510. The inner wall of the traction frame 510 is precision ground to serve as a guide rail.

[0040] On the adjacent side of the first traction beam 545 and the second traction beam 555, that is, on the surfaces facing each other, a plurality of airbag-type damping cylinders are fixedly connected.

[0041] Specifically, a first airbag-type damping cylinder 544 is fixedly connected to the rear end and front end of the lower surface of the first traction beam 545, and a second airbag-type damping cylinder 554 is fixedly connected to the corresponding position on the upper surface of the second traction beam 555.

[0042] Each pneumatic damping cylinder has a movable plate fixedly connected to its movable end, i.e., the end of its piston rod. The upper movable plate is the first movable plate 543, and the lower movable plate is the second movable plate 553.

[0043] On the adjacent side of the first movable plate 543 and the second movable plate 553, that is, on the surfaces facing each other, a bracket is fixedly connected to each other, the upper one being the first bracket 542 and the lower one being the second bracket 552.

[0044] Each bracket is U-shaped, and a transport roller for directly contacting and pulling the profile 700 is rotatably connected to the inside of the bracket via a high-precision ball bearing. The upper one is the first transport roller 541, and the lower one is the second transport roller 551. The axes of the first transport roller 541 and the second transport roller 551 are parallel to each other and parallel to the forward direction of the profile 700.

[0045] A traction motor 560 is fixedly connected to the front exterior of the first bracket 542. The output shaft of the traction motor 560 passes through the side wall of the first bracket 542 via a coupling and is fixedly connected to the central shaft of the first transport roller 541.

[0046] When the traction motor 560 is powered on, its output shaft drives the first transport roller 541 to rotate. The friction between the first transport roller 541 and the upper surface of the profile 700, and the support provided by the second transport roller 551 from below, work together to achieve the traction and transport of the profile 700.

[0047] In order to achieve synchronous centering adjustment of the traction mechanism 500 for profiles 700 of different diameters, the top ends of the first bidirectional lead screw 521 and the second bidirectional lead screw 522 both pass through the top wall plate of the traction frame 510 and are respectively fixedly connected to a driven rotating gear.

[0048] Specifically, a second rotating gear 534 is fixedly connected to the top end of the first bidirectional lead screw 521, and a third rotating gear 535 is fixedly connected to the top end of the second bidirectional lead screw 522.

[0049] A rotating assembly 530 is located at the top center of the traction frame 510. Specifically, a vertically arranged rotating rod 532 is rotatably connected to it via a precision bearing seat. The rotating rod 532 can rotate freely around its own axis. A handle 531 is fixedly connected to the top of the rotating rod 532 for easy gripping and force application by the operator. A drive rotating gear, called the first rotating gear 533, is fixedly connected to the bottom of the outer wall of the rotating rod 532, near the lower end of the rotating rod 532.

[0050] The tooth profile of the first rotating gear 533 meshes with the tooth profiles of the second rotating gear 534 and the third rotating gear 535 simultaneously, forming a single-stage gear transmission system.

[0051] When the operator rotates the handle 531, the handle 531 drives the rotating rod 532 and the first rotating gear 533 to rotate synchronously. The first rotating gear 533 transmits power and motion to the second rotating gear 534 and the third rotating gear 535 meshing with it, thereby driving the first bidirectional lead screw 521 and the second bidirectional lead screw 522 to rotate in a completely synchronized manner.

[0052] Since the rotation speed and direction of the first bidirectional lead screw 521 and the second bidirectional lead screw 522 are completely consistent, they drive the first traction beam 545 and the second traction beam 555 above and below them to move in precise synchronous opposite or opposite directions. This ensures that the symmetrical center plane of the first transport roller 541 and the second transport roller 551 always coincides with the center line of the production device that has been pre-calibrated, thus achieving mechanically forced synchronous alignment without the need for repeated manual calibration.

[0053] Furthermore, in the traction mechanism 500, each airbag damping cylinder is connected to an external compressed air source, and its internal air pressure can be independently adjusted via a precision pressure regulating valve. When the first transport roller 541 and the second transport roller 551 contact the surface of the profile 700 after synchronous alignment adjustment, the airbag damping cylinder is not rigidly locked. Instead, it utilizes the elasticity of the compressible gas inside the airbag damping cylinder to provide an adjustable flexible buffer layer for the profile 700 between the first roller assembly 540 and the second roller assembly 550.

[0054] This makes the clamping force applied by the first transport roller 541 and the second transport roller 551 to the surface of the profile 700 elastic and floating, which can adaptively compensate for small fluctuations in the diameter of the profile 700 or ellipticity errors. While ensuring sufficient traction friction, it minimizes the flattening, indentation or cracking damage caused by rigid hard contact to the thin-walled, fragile profile 700.

[0055] The following describes in detail the specific structure, assembly relationship, and positional layout of the cutting mechanism 400 with respect to the traction mechanism 500 and the cooling mechanism 300. The cutting mechanism 400 is located on the top right side of the worktable 100 and between the cooling mechanism 300 and the traction mechanism 500.

[0056] Specifically, from the production flow of profile 700, the extrusion shaping mechanism 200 is at the far left, the cooling mechanism 300 is right next to it, the cutting mechanism 400 is located to the right of the cooling mechanism 300, and the traction mechanism 500 is located to the right of the cutting mechanism 400, which is the end of the entire production line.

[0057] Please refer to Figures 5-6 The core function of the cutting mechanism 400 is to achieve precise cutting of the continuously moving profile 700 without stopping the machine. The main supporting and moving parts of the cutting mechanism 400 include a linear motor 410, a slide table 420, a first ring 430 and a second ring 440.

[0058] The linear motor 410 adopts a U-shaped groove design, which has extremely high dynamic response speed and positioning accuracy. The stator part of the linear motor 410, namely the guide rail and magnetic rail, is fixedly connected to the top right side plane of the worktable 100, and its laying direction is strictly parallel to the forward direction of the profile 700.

[0059] The mover of the linear motor 410, namely the slide table 420, is slidably connected to the guide rail of the linear motor 410, and can perform precise linear reciprocating motion along the guide rail without contact or friction under the electromagnetic force drive of the linear motor 410.

[0060] On the top plane of the slide 420, a first ring 430 is fixedly connected by multiple high-strength bolts. The axis of the first ring 430 coincides with the theoretical center line of the profile 700.

[0061] The inner ring of the first ring 430 is machined with a precision sliding surface. A second ring 440 is slidably connected to the inner side of the first ring 430 through a sliding bearing or ball sleeve, so that the second ring 440 can rotate freely relative to the first ring 430 about their common axis, while the axial and radial clearance between the two is controlled within a very small range.

[0062] The inner surface of the second ring 440 is machined into a smooth surface to reduce frictional resistance with the profile 700 passing through it, while the outer surface is machined with a complete and precise cut groove 441, which is used to mesh with an external drive gear to transmit rotational motion.

[0063] At the bottom front side of the first ring 430, a through groove 431 is provided that penetrates the wall plate of the first ring 430. The size and position of the through groove 431 are precisely designed so that the cutting tooth groove 441 of the outer ring of the second ring 440 can be fully exposed to the external environment when rotating through the position of the through groove 431, which facilitates contact with the drive gear.

[0064] In order to achieve controlled rotation of the second ring 440, the cutting mechanism 400 also includes a set of rotary cutting components 450, which consists of a rotary cutting motor 451 and a rotary cutting gear 452.

[0065] The rotary cutting motor 451 is a servo motor with precise speed and position control capabilities. The rotary cutting motor 451 is fixedly connected to the top front side of the slide table 420 via a motor mounting bracket, and the axis of the output shaft is parallel to the horizontal plane.

[0066] The rotary cutting gear 452 is fixedly mounted on the output shaft of the rotary cutting motor 451 via a key connection. The tooth profile of the rotary cutting gear 452 meshes with the cutting tooth groove 441 on the outer ring of the second ring 440 exposed at the aforementioned through groove 431.

[0067] When the rotary cutting motor 451 is powered on, the output shaft drives the rotary cutting gear 452 to rotate. The rotary cutting gear 452 drives the second ring 440 to make a precise circular rotation around its own central axis within the first ring 430 through gear meshing transmission.

[0068] In order to achieve radial cutting of the cutting tool into the profile 700, the cutting mechanism 400 also includes a fixed-point cutting component 460, which is installed in the internal space of the second ring 440.

[0069] The fixed-point cutting assembly 460 includes a first electric telescopic rod 461, a second electric telescopic rod 462, a first guide rod 466, a second guide rod 467, a tray 465, a fixed-point cutting motor 463, and a fixed-point cutting blade 464.

[0070] At the inner top of the second ring 440, that is, on the inner upper surface of the circumferential wall of the second ring 440, along the diametrical direction of the second ring 440, a first guide rod 466 and a second guide rod 467 are fixedly connected.

[0071] The axes of the first guide rod 466 and the second guide rod 467 are parallel to each other and are both parallel to the diameter direction of the second ring 440, that is, parallel to the radial direction of the profile 700.

[0072] Inside the second ring 440, between the first guide rod 466 and the second guide rod 467, a tray 465 is provided. The upper surface of the tray 465 has multiple guide holes. The first guide rod 466 and the second guide rod 467 pass through the corresponding guide holes on the tray 465, forming a sliding connection structure with the tray 465, providing precise guidance for the up and down movement of the tray 465.

[0073] On the upper surface of the tray 465, a first electric telescopic rod 461 and a second electric telescopic rod 462 are also fixedly connected.

[0074] The cylinder ends of the first electric telescopic rod 461 and the second electric telescopic rod 462 are fixed to the inner top of the second ring 440, while the retractable piston rod ends of the first electric telescopic rod 461 and the second electric telescopic rod 462 are fixedly connected to the upper surface of the tray 465.

[0075] When the first electric telescopic rod 461 and the second electric telescopic rod 462 extend or retract simultaneously, they can drive the tray 465 to make precise linear movements along the axial direction of the first guide rod 466 and the second guide rod 467, that is, in the radial direction perpendicular to the axis of the profile 700.

[0076] On the upper surface of the tray 465, a fixed-point cutting motor 463 is fixedly connected. The output axis of the fixed-point cutting motor 463 extends laterally and is fixedly connected to a high-speed rotating fixed-point cutting head 464. The fixed-point cutting head 464 is made of ultra-hard and ultra-thin material, and has extremely high sharpness and wear resistance.

[0077] Next, the specific structure, assembly relationship, and connection layout of the cooling mechanism 300 with the extrusion shaping mechanism 200 and the cutting mechanism 400 will be described in detail.

[0078] Please refer to Figures 7-8 The cooling mechanism 300 is located on the upper center of the workbench 100, connected to the extrusion and shaping mechanism 200 on its left and adjacent to the cutting mechanism 400 on its right. The cooling mechanism 300 mainly includes a first pipe 310, a second pipe 320, a cooling transport assembly 340, and cooling liquid.

[0079] The first tube 310 is a cylindrical shell with a large diameter, and both ends of the first tube 310 have flange interfaces. The first tube 310 is fixedly installed above the workbench 100 by a tube support, and its central axis is strictly coincident with the center line of the entire production device.

[0080] On the rear wall of the first tube 310, a long strip window 311 is provided along its length. This window 311 is used to expose internal components and facilitate assembly and maintenance.

[0081] Inside the first tube 310, a second tube 320 is coaxially fitted. The outer diameter of the second tube 320 is slightly smaller than the inner diameter of the first tube 310, and the two form an annular, closed cavity, which is called the cooling closed cavity 330.

[0082] The second tube 320 can rotate freely relative to the first tube 310 around the common axis of the first tube 310 and the second tube 320. High-precision rotary sealing structures are provided at both end faces of the first tube 310 and the second tube 320 to ensure that the cooling liquid in the cooling sealed cavity 330 does not leak.

[0083] At the top left of the first pipe 310, there is an inlet 312 that communicates with the cooling closed cavity 330 for injecting cooling water or other cooling liquid into the cooling closed cavity 330.

[0084] At the top right side of the first pipe 310, there is an outlet 313 that communicates with the cooling closed chamber 330 to discharge the hot cooling liquid that has absorbed heat, forming a circulating cooling circuit.

[0085] On the front side of the inner wall of the second pipe 320, that is, on the side near the window 311 of the first pipe 310, a plurality of spray heads 321 are equidistantly arranged along the length of the second pipe 320.

[0086] The liquid inlet end of each spray head 321 is connected to the cooling closed cavity 330 between the first pipe 310 and the second pipe 320 through a pipe or a direct opening, while its spray end faces the internal space of the second pipe 320, that is, towards the surface of the profile 700 passing through the second pipe 320.

[0087] A ring of precision cooling grooves 322 is machined around the middle of the outer side of the second tube 320. In order to drive the second tube 320 to rotate, the cooling mechanism 300 also includes a cooling transport assembly 340.

[0088] The cooling transport assembly 340 includes a support plate 341, a cooling rotary gear 342, and a cooling motor 343.

[0089] The support plate 341 is an L-shaped metal plate, the bottom of which is fixedly connected to the upper front part of the workbench 100 by bolts, forming a stable cantilever support structure.

[0090] The cooling motor 343 is fixedly mounted on the left front end of the support plate 341 by bolts, and the output shaft is perpendicular to the forward direction of the profile 700. The cooling rotary gear 342 is fixedly mounted on the output shaft of the cooling motor 343 by key connection.

[0091] The position of the cooling rotating gear 342 is precisely set so that it can pass through the window 311 opened on the rear side of the first tube 310 and mesh with the cooling tooth groove 322 exposed on the outer wall of the second tube 320.

[0092] When the cooling motor 343 is powered on, the output shaft drives the cooling rotating gear 342 to rotate. The cooling rotating gear 342, through gear tooth meshing, forces the second tube 320 to make continuous and stable rotational motion around its central axis inside the first tube 310.

[0093] The extrusion shaping mechanism 200 is located at the beginning of the production unit, specifically on the top left side of the worktable 100. The extrusion shaping mechanism 200 mainly comprises an extruder 210 and a shaping tube 220.

[0094] The extruder 210 is a standard single-screw or twin-screw extruder 210 used to heat and melt granular or powdered raw materials (such as polylactic acid PLA) and plasticize them into a homogeneous melt, which is then extruded from the die head at a constant pressure and flow rate.

[0095] The shaping tube 220 is a metal tube with a precise inner diameter and length. Its left end is fixedly connected to the die head outlet of the extruder 210 via a flange, and its right end is fixedly connected to the left end of the first tube 310 of the cooling mechanism 300.

[0096] The molten tubular profile 700 extruded from the die head of extruder 210 directly enters the shaping tube 220, where it undergoes initial dimensional stabilization and outer wall shaping under the constraint of the shaping tube 220.

[0097] Finally, to coordinate and control the automated operation of the entire production unit, the unit also includes a control mechanism 600. At the core of the control mechanism 600 is a programmable logic controller (PLC) or industrial computer, which is electrically connected via signal cables to the traction motor 560 in the traction mechanism 500, the rotary cutting motor 451, the fixed-point cutting motor 463 in the cutting mechanism 400, the first electric telescopic rod 461, the second electric telescopic rod 462, the linear motor 410, and the cooling motor 343 in the cooling mechanism 300.

[0098] The control mechanism 600 receives feedback signals from various sensors and, according to preset programs and logic, precisely controls the start, stop, speed, and direction of each motor, as well as the extension and retraction of the electric telescopic rod, ensuring that the entire production process is coordinated, precise, and efficient.

[0099] The following describes the working process of the entire production unit: When the production unit is started and ready to produce, the operator first pre-adjusts the traction mechanism 500 according to the diameter specification of the profile to be produced (700).

[0100] The operator manually rotates the handle 531, which drives the rotating rod 532 and the first rotating gear 533 to rotate. The first rotating gear 533 simultaneously drives the second rotating gear 534 and the third rotating gear 535, which in turn drive the first bidirectional lead screw 521 and the second bidirectional lead screw 522 to rotate synchronously.

[0101] Since the upper and lower threads of each bidirectional lead screw rotate in opposite directions, the rotational motion is converted into the synchronous, opposite movement of the first traction beam 545 and the second traction beam 555 along the lead screw axis. The first traction beam 545 and the second traction beam 555 drive the first transport roller 541 and the second transport roller 551 to move closer together through their respective airbag damping cylinders, movable plates, and supports.

[0102] The operator observes the limiting block and ensures that the gap between the first transport roller 541 and the second transport roller 551 is slightly larger than the theoretical diameter of the profile 700. At this time, a suitable air pressure value is preset for all airbag damping cylinders through the pressure regulating valve. This air pressure value determines the flexible clamping force when clamping the profile 700 subsequently.

[0103] Since the first rotating gear 533 simultaneously drives the second rotating gear 534 and the third rotating gear 535, and the pitch and direction of the two bidirectional lead screws are exactly the same, the movements of the first transport roller 541 and the second transport roller 551 are symmetrical. Their symmetrical center plane is mechanically locked on the center line pre-calibrated by the production device, achieving fast and precise synchronous alignment.

[0104] After the pre-adjustment is completed, the entire production unit enters continuous operation. First, the control mechanism 600 issues a command to start the extruder 210. The raw material is heated and melted and continuously extruded from the die head to form a molten tubular profile 700.

[0105] The profile 700 then enters the shaping tube 220, which is fixedly connected to the die head of the extruder 210. Under the constraint of the inner wall of the shaping tube 220, the outer diameter and roundness of the profile 700 are precisely pre-shaped. The profile 700 exiting from the right end of the shaping tube 220 is still at a high temperature and needs to be cooled and cured immediately.

[0106] Next, the profile 700 enters the cooling mechanism 300, and the control mechanism 600 simultaneously starts the cooling motor 343 of the cooling mechanism 300 and opens the cooling water supply at the water inlet 312.

[0107] The cooling motor 343 drives the cooling rotating gear 342 to rotate. The cooling rotating gear 342 engages with the cooling tooth groove 322 on the outer wall of the second tube 320, forcibly driving the second tube 320 to rotate continuously and at high speed inside the first tube 310. At the same time, cooling water enters the cooling closed cavity 330 between the first tube 310 and the second tube 320 from the inlet 312 and continuously fills the entire cavity.

[0108] As the second pipe 320 rotates, multiple spray heads 321, fixedly installed on the front side of the inner wall of the second pipe 320, also rotate 360 ​​degrees around the profile 700. During the rotation, the cooling water in the cooling sealed cavity 330 is continuously sprayed out from each spray head 321 under pressure, forming a high-pressure water curtain that is evenly sprayed onto the entire circumferential surface of the profile 700 that passes through the interior of the second pipe 320.

[0109] This dynamic rotating spray method can actively break the vapor film thermal boundary layer formed on the surface of profile 700 due to high temperature cooling, so that the cooling rate of each point on the circumference of profile 700 is highly consistent, effectively preventing thermal stress bending caused by uneven cooling.

[0110] The cooling water that has absorbed the heat from the profile 700 becomes hot water and is discharged from the outlet 313. It then enters the external cooling circulation system for further treatment and reuse. After passing through the cooling mechanism 300, the profile 700 has completely solidified from a molten state into a solid pipe with a certain strength and elasticity.

[0111] The cured profile 700 is output from the right end of the cooling mechanism 300, then passes through the inner hole of the second ring 440 of the cutting mechanism 400, and continues forward into the traction mechanism 500. The control mechanism 600 issues a command to start the traction motor 560 of the traction mechanism 500.

[0112] The traction motor 560 drives the first transport roller 541 to rotate. Since the first transport roller 541 and the second transport roller 551 have been pre-aligned according to the diameter of the profile 700, and under the push of the airbag damping cylinder, they are tightly attached to the upper and lower surfaces of the profile 700 with a set flexible pressure.

[0113] The rotational friction of the first transport roller 541 drives the profile 700 to move forward continuously. During this process, the gas inside the airbag damping cylinder is compressed, providing elastic floating characteristics for the clamping system.

[0114] When the diameter of profile 700 shows a slight positive deviation, the first transport roller 541 is slightly lifted upwards, increasing the air pressure in the airbag damping cylinder and slightly increasing the clamping force, but without causing rigid crushing. When the diameter of profile 700 shows a slight negative deviation, the airbag damping cylinder pushes the first transport roller 541 downwards to follow, always ensuring close contact between the two surfaces and maintaining stable traction friction. This flexible adaptive mechanism ensures that the thin-walled profile 700 will not be flattened or damaged due to fluctuations in clamping force during traction.

[0115] The traction mechanism 500 continuously pulls the profile 700 forward at a constant speed. When the length of the profile 700 being pulled reaches the preset cutting length, the control mechanism 600 starts the cutting cycle of the cutting mechanism 400. This cutting cycle is the key to the high-precision collaborative work between the traction mechanism 500 and the cutting mechanism 400.

[0116] The control mechanism 600 first sends a command to the linear motor 410 of the cutting mechanism 400, driving the slide table 420 to begin accelerating. Through real-time speed feedback from the encoder and closed-loop control, the speed of the slide table 420 is precisely accelerated to be equal to the traction speed of the traction mechanism 500 on the profile 700.

[0117] Since the slide table 420 and the profile 700 move in the same direction at the same speed, the first ring 430, the second ring 440 and all cutting components fixedly installed on the slide table 420 are in a relatively stationary state with respect to the profile 700, which is also in motion. This creates the primary condition for non-stop cutting.

[0118] Once the slide table 420 and the profile 700 reach a relatively stationary state, the control mechanism 600 issues the next command to activate the fixed-point cutting component 460. Specifically, the control mechanism 600 simultaneously issues extension commands to the first electric telescopic rod 461 and the second electric telescopic rod 462.

[0119] The piston rods of the first electric telescopic rod 461 and the second electric telescopic rod 462 extend synchronously, pushing the tray 465 along the guide of the first guide rod 466 and the second guide rod 467 to move towards the surface of the profile 700. At the same time, the control mechanism 600 also starts the fixed-point cutting motor 463 fixedly installed on the tray 465.

[0120] The fixed-point infeed motor 463 drives the fixed-point infeed cutter head 464 on its output shaft to start rotating at an extremely high speed. When the tray 465 is pushed to the predetermined position, the high-speed rotating fixed-point infeed cutter head 464 begins to contact and cut into the wall of the profile 700, realizing radial fixed-point infeed.

[0121] At this time, the control mechanism 600 maintains the radial pressure of the fixed-point cutting head 464, so that its cutting depth reaches a certain proportion of the profile wall thickness 700, but it has not yet completely cut off.

[0122] Immediately afterwards, the control mechanism 600 issues a command to start the rotary cutting assembly 450, and the rotary cutting motor 451 is powered on and runs, driving the rotary cutting gear 452 on its output shaft to rotate.

[0123] The rotating cutting gear 452 drives the entire second ring 440 and all the fixed-point cutting components 460 installed inside it (including the fixed-point cutting blade 464 that has already cut into the profile 700) to rotate around the central axis of the profile 700 by meshing with the cutting groove 441 on the outer ring of the second ring 440.

[0124] As the second ring 440 rotates, the fixed-point cutting head 464 maintains its rotation and radial cutting depth while revolving 360 degrees around the profile 700. During this revolution, the fixed-point cutting head 464 continuously cuts the wall of the profile 700 along the circumferential direction. After the second ring 440 has rotated one revolution, the fixed-point cutting head 464 has completely cut the profile 700.

[0125] After the cutting is completed, the control mechanism 600 issues a reset command in reverse order. First, the rotary cutting motor 451 stops or reverses its rotation, causing the second ring 440 to reset. Then, the first electric telescopic rod 461 and the second electric telescopic rod 462 retract, lifting the tray 465 and the fixed-point cutting blade 464 off the surface of the profile 700. Finally, the linear motor 410 drives the slide table 420 to accelerate rapidly in the reverse direction, returning to the starting position, ready for the next cutting cycle.

[0126] Since the cutting process is completed in a state where the slide table 420 and the profile 700 are relatively stationary, the end face of the cut profile 700 is extremely perpendicular to the axis, the cut is flat and smooth, and there are no burrs. Moreover, the traction mechanism 500 never stops during the entire production process, realizing true non-stop continuous production.

[0127] Throughout the production process, the control mechanism 600 continuously monitors key parameters such as traction speed, cutting length, cutting frequency, cooling motor speed 343, and extruder speed 210, and makes real-time adjustments based on preset formulas or operator instructions.

[0128] The control mechanism 600 is also responsible for coordinating the start-up and shutdown sequence of each mechanism: when starting, the cooling cycle and extruder 210 are started first. After the profile 700 has stably passed through the cutting mechanism 400 and the traction mechanism 500, the automatic cycle of the traction mechanism 500 and the cutting mechanism 400 is started. When stopping, the extruder 210 is stopped first. After the profile 700 is completely pulled out from the traction mechanism 500, the traction mechanism 500, the cutting mechanism 400 and the cooling mechanism 300 are stopped in sequence.

[0129] Through this precise and orderly automatic control, the production apparatus of the present invention for aerosol generation product profile 700 can produce high-quality thin-walled tubular, strip or columnar profiles 700 in a long-term, stable and efficient manner, especially PLA cooling pipes for heating non-combustible cigarettes.
