Description

Technical Field

[0001] This invention relates to the field of fiber coating technology, and more specifically, to a fiber coating device for gas cylinder production. Background Technology

[0002] To increase the strength of steel gas cylinders, it is necessary to wrap the outer layer with resin-impregnated fibers. After the fibers are coated with resin, they are wrapped onto the gas cylinder. However, after the resin-impregnated fibers undergo a curing process, defects such as uneven surface, lumps, slippage, loose yarn, and fuzz are prone to occur. The amount of resin coating on the fibers and the uniformity of the coating directly affect the quality of the gas cylinder. Therefore, it is necessary to scrape the resin off the fibers. Under low-temperature conditions, the viscosity of the epoxy resin in the external impregnated fibers of the gas cylinder increases exponentially. Most existing scraping devices are rigid and fixed structures. When the high-viscosity resin passes through the narrow scraping gap, it generates huge flow resistance on the fiber bundle. This resistance makes it difficult for the fibers to be uniformly wetted when passing through the scraper blade. The instantaneous shear force at the contact point between the fiber bundle and the scraper blade increases dramatically, exceeding the surface wear resistance threshold of the fiber. This results in wear on the fiber surface coating and defects in single filament breakage. These micro-damages will expand under subsequent winding tension and become stress concentration points when the gas cylinder explodes. Summary of the Invention

[0003] To overcome the above-mentioned technical problems, the present invention proposes a device for scraping adhesive to wrap fibers during gas cylinder production.

The traction unit, mounted on the frame, includes a guide plate that matches the outer contour of the gas cylinder and a traction component for driving the scraping unit to move axially along the gas cylinder. When the scraping unit moves axially relative to the gas cylinder, the guide plate guides the scraping unit to move radially according to the change in the contour of the gas cylinder, so that the distance between the scraping unit and the contact surface of the gas cylinder remains consistent.

[0005] As a further aspect of the present invention: the gas cylinder rotating unit includes a rotary drive motor fixed on the frame, the output end of the rotary drive motor is connected to a drive shaft, and the end of the drive shaft away from the rotary drive motor is provided with a bottom tray adapted to the bottom of the gas cylinder.

[0006] As a further aspect of the present invention: the adhesive scraping unit includes a mounting platform, a blade holder is provided below the mounting platform, a scraper is rotatably mounted on the blade holder, and a counterweight is provided above the mounting platform.

[0007] As a further embodiment of the present invention: the traction unit further includes a transverse guide rail fixed horizontally on the frame and a transverse traction platform slidably mounted on the transverse guide rail. The transverse traction platform is provided with a transverse slider adapted to the transverse guide rail. A vertical guide rail is provided on the side end face of the transverse traction platform facing the mounting platform. A vertical slider adapted to the vertical guide rail is provided on the mounting platform. The guide plate is fixed on the frame, and the mounting platform is provided with a guide rod adapted to the guide plate. The traction component is used to drive the transverse traction platform to move laterally along the transverse guide rail.

[0008] As a further embodiment of the present invention: the traction component includes a traction shaft rotatably mounted at both ends of the frame, a traction wheel is mounted on the traction shaft, a traction belt is connected between the two traction wheels, and the transverse traction platform is fixed on the traction belt; a first bevel gear is provided on one end of the traction shaft, and a second bevel gear meshing with the first bevel gear is provided on the drive shaft.

[0009] As a further embodiment of the present invention: a piston rod is fixed inside the sleeve, a piston cavity is opened inside the movable telescopic rod, the piston rod movably passes through the movable telescopic rod and extends into the piston cavity, and a top support spring is movably sleeved on one end of the piston rod extending out of the movable telescopic rod.

[0010] As a further embodiment of the present invention: the top support includes an end head, and an axial sliding cavity is provided at one end of the end head facing the gas cylinder. An axial pressure plate is slidably embedded in the axial sliding cavity, and a plurality of return springs that abut against the axial pressure plate are provided in the axial sliding cavity. The end head is also provided with several sets of radial grooves in the circumferential direction. A radial slider is slidably embedded in the radial groove. A connecting rod is hinged between the radial slider and the axial pressure plate. A radial expansion rod is rotatably mounted on the radial slider. An inner flexible bladder is provided at the end of the radial expansion rod away from the radial slider. A sliding pin is provided on the inner wall of the end head. A strip-shaped groove adapted to the sliding pin is opened in the middle of the radial expansion rod.

[0011] As a further aspect of the present invention: the end of the movable telescopic rod facing the top support is provided with a jet air passage communicating with the piston chamber; a transition air chamber is provided at one end of the sleeve; and the movable telescopic rod is provided with a plurality of through holes in the circumferential direction communicating with the piston chamber and the transition air chamber.

[0012] As a further aspect of the present invention: the inflatable component includes an air storage chamber disposed within a sleeve, an air inlet is provided at the bottom of the air storage chamber, and an air pipe is connected between the air inlet and the transition air chamber.

[0013] As a further embodiment of the present invention: an inner partition ring is provided on the inner side of the end, and an annular venting channel is formed between the inner partition ring and the axial pressure plate. A plurality of vent holes communicating with the annular venting channel are provided on the outer circumferential side of the axial pressure plate.

[0014] The beneficial effects of this invention are: This invention, through the coordinated action of a guide plate and a traction unit that match the outer contour of the gas cylinder, enables the scraping unit to automatically perform corresponding radial compensation according to the contour changes of the gas cylinder when it moves along the axial direction of the gas cylinder. This ensures that the contact distance between the scraping unit and the surface of the gas cylinder remains constant, keeps the fiber thickness of each part of the outer surface of the gas cylinder consistent, and ensures that the adhesive layer is evenly and smoothly distributed, thereby improving the dynamic balance and load uniformity of the gas cylinder. By continuously introducing high-temperature gas into the gas cylinder through the inflation component, the temperature of the gas cylinder body is increased, which effectively reduces the viscosity of the epoxy resin liquid at the moment of scraping. This significantly reduces the flow resistance of the high-viscosity liquid to the fiber bundle, avoiding the surge in instantaneous shear force caused by the hard pulling of the fiber bundle at the scraper edge. This eliminates coating wear and monofilament breakage on the fiber surface, not only protecting the integrity of the fiber but also preventing the possibility of micro-damage expansion under subsequent winding tension, thus improving the structural integrity of the composite material.

[0018] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed only to enable those skilled in the art to better understand and implement the subject matter described herein, and changes may be made to the function and arrangement of the elements discussed without departing from the scope of this specification. Various processes or components may be omitted, substituted, or added as needed in the examples. Furthermore, features described in some examples may be combined in other examples.

[0019] Please see Figure 1 and Figure 2 The present invention discloses a device for scraping glue on wound fiber in the production of gas cylinders, including a frame 100, a gas cylinder rotating unit 200, a top support clamping unit 300, a glue scraping unit 400 and a traction unit 500. Please see Figure 3 The cylinder rotation unit 200 is located at one end of the frame 100 and is adapted to the bottom of the cylinder 600, and is used to drive the cylinder 600 to rotate circumferentially; the top support clamping unit 300 is located at the other end of the frame 100 and is adapted to the cylinder rotation unit 200, including a sleeve 310 and a movable telescopic rod 320 movably embedded in the sleeve 310. The end of the movable telescopic rod 320 facing the cylinder rotation unit 200 is provided with a top support member 330 adapted to the mouth of the cylinder 600; the sleeve 310 is also provided with an inflation member 340 connected to the movable telescopic rod 320, and the inflation member 340 continuously introduces high-temperature gas into the cylinder 600 through the movable telescopic rod 320; Please see Figure 4 The scraping unit 400 is movably disposed above the gas cylinder 600 and is used to scrape adhesive onto the outer surface of the gas cylinder 600. The traction unit 500 is disposed on the frame 100 and includes a guide plate 510 that matches the outer contour of the gas cylinder 600 and a traction member 580 for driving the scraping unit 400 to move axially along the gas cylinder 600. When the scraping unit 400 moves axially relative to the gas cylinder 600, the guide plate 510 guides the scraping unit 400 to move radially according to the contour change of the gas cylinder 600, so that the contact distance between the scraping unit 400 and the gas cylinder 600 remains consistent.

[0020] Specifically, the bottom of the gas cylinder 600 is placed against one end of the gas cylinder rotating unit 200, and then the top support 330 at the end of the movable telescopic rod 320 is placed against the mouth of the gas cylinder 600. The top support 330 applies an axial thrust to the gas cylinder 600, thereby clamping and fixing the gas cylinder 600 between the gas cylinder rotating unit 200 and the top support clamping unit 300. Subsequently, the gas cylinder rotating unit 200 drives the gas cylinder 600 to rotate circumferentially at a uniform speed. During the rotation of the gas cylinder 600, the adhesive scraping unit 400 performs adhesive scraping treatment on the outer surface of the gas cylinder 600. At the same time, the adhesive scraping unit 400 is in contact with the traction unit. Under the lateral traction of the 500 unit, the adhesive scraper unit 400 moves at a constant speed along the axial direction of the gas cylinder 600. Since the guide plate 510 is consistent with the outer contour of the gas cylinder 600, the adhesive scraper unit 400 can also adaptively adjust radially when moving axially, so that the distance between the adhesive scraper unit 400 and the contact position of the gas cylinder 600 remains consistent, improving the smoothness of the adhesive scraping and the consistency of fiber thickness in various parts of the gas cylinder 600. During the adhesive scraping process, high-temperature gas is continuously introduced into the gas cylinder 600 through the inflation component 340, thereby increasing the temperature of the entire gas cylinder 600, reducing the viscosity of the adhesive, and avoiding stress concentration during adhesive scraping.

[0021] It should be noted that, through the coordinated action of the guide plate 510 matching the outer contour of the gas cylinder 600 and the traction unit 500, the adhesive scraping unit 400 can automatically perform corresponding radial compensation according to the contour change of the gas cylinder 600 when it moves along the axial direction of the gas cylinder 600. This ensures that the contact distance between the adhesive scraping unit 400 and the surface of the gas cylinder 600 remains constant, so that the fiber thickness of each part of the outer surface of the gas cylinder 600 is consistent, the adhesive layer is evenly and flatly distributed, and the dynamic balance and load uniformity of the gas cylinder 600 are improved. High-temperature gas is continuously introduced into the gas cylinder 600 through the inflation component 340, raising the temperature of the gas cylinder 600 body and effectively reducing the viscosity of the epoxy resin liquid at the moment of scraping. This significantly reduces the flow resistance of the high-viscosity liquid to the fiber bundle, avoiding the sudden increase in instantaneous shear force caused by hard pulling at the scraper edge of the fiber bundle. This eliminates coating wear and monofilament breakage on the fiber surface, not only protecting the integrity of the fiber but also preventing the possibility of micro-damage expansion under subsequent winding tension, thus improving the structural integrity of the composite material. This invention fundamentally optimizes the microstructure and macroscopic quality of composite materials by eliminating initial micro-damage to fibers and ensuring uniform fiber distribution. The fiber bundles withstand tension under optimal wetting conditions, avoiding early failure caused by local stress concentration. It effectively eliminates potential stress concentration points in the subsequent pressure bursting process of the gas cylinder, thereby improving the bursting pressure value and cyclic fatigue life of the gas cylinder and fundamentally enhancing its load-bearing capacity.

[0022] In one embodiment, please refer to Figure 3The gas cylinder rotating unit 200 includes a rotary drive motor 210 fixed on the frame 100. The output end of the rotary drive motor 210 is connected to a drive shaft 220. The end of the drive shaft 220 away from the rotary drive motor 210 is provided with a bottom tray 230 adapted to the bottom of the gas cylinder 600. Specifically, the gas cylinder 600 is clamped between the bottom tray 230 and the top support 330. The bottom tray 230 can be made of soft materials such as rubber, which can not only increase the friction between the gas cylinder 600 and the cylinder, but also effectively prevent damage to the outer fiber layer of the gas cylinder 600. By rotating the drive motor 210 to drive the drive shaft 220 and the bottom tray 230 to rotate, the gas cylinder 600 can be driven to rotate circumferentially.

[0023] It should be noted that by using soft materials such as rubber on the bottom tray 230 that contacts the bottom of the gas cylinder 600, the mechanical damage that traditional rigid clamping mechanisms may cause to the surface of the gas cylinder is fundamentally avoided. When the gas cylinder 600 is not fully cured or the outer fiber is relatively fragile, this flexible contact can effectively absorb the clamping pressure and prevent the wound fiber layer from being crushed or having surface indentations, thereby ensuring the integrity of the external structure and the surface smoothness of the gas cylinder 600 from the initial winding stage to the entire process of scraping and curing. When the soft-material bottle bottom tray 230 contacts the bottom of the gas cylinder 600, it can generate a greater static friction force than rigid metal, ensuring that the torque output by the rotary drive motor 210 can be smoothly transmitted to the gas cylinder 600, so that the gas cylinder 600 strictly follows the drive shaft 220 to rotate circumferentially, avoiding the fluctuation of winding tension or the deviation of the scraping path caused by slippage, thereby improving the overall accuracy of winding molding.

[0024] Further, please refer to Figure 4 , Figure 5 and Figure 6 The glue scraping unit 400 includes a mounting platform 410, a blade holder 420 is provided below the mounting platform 410, a scraper 430 is rotatably mounted on the blade holder 420, and a counterweight 440 is provided above the mounting platform 410. The traction unit 500 also includes a transverse guide rail 520 horizontally fixed on the frame 100 and a transverse traction table 530 slidably mounted on the transverse guide rail 520. The transverse traction table 530 is provided with a transverse slider 540 adapted to the transverse guide rail 520. A vertical guide rail 550 is provided on the side end face of the transverse traction table 530 facing the mounting platform 410. A vertical slider 560 slidably adapted to the vertical guide rail 550 is provided on the mounting platform 410. The guide plate 510 is fixed on the frame 100, and the mounting platform 410 is provided with a guide rod 570 adapted to the guide plate 510. The traction member 580 is used to drive the transverse traction platform 530 to move laterally along the transverse guide rail 520. Specifically, when the cylinder rotating unit 200 drives the cylinder 600 to rotate circumferentially, it can synchronously drive the transverse traction table 530 to move laterally (i.e., along the axial direction of the cylinder 600) along the transverse guide rail 520 under the transmission of the traction member 580. In this way, the scraper 430 under the mounting platform 410 can be moved along the axial direction of the cylinder 600 to achieve adhesive scraping treatment on the entire body of the cylinder 600. When the scraper 430 moves axially relative to the cylinder 600 with the transverse traction table 530, the guide rod 570 also moves along the guide plate 510. The square outline moves, and under the counterweight of the counterweight seat 440, it can drive the entire mounting platform 410 to move vertically along the vertical guide rail 550 (i.e., along the radial direction of the gas cylinder 600). Since the outline of the guide plate 510 is consistent with the outer outline of the gas cylinder 600, the scraper 430 can automatically adjust its height according to the outer outline of the gas cylinder 600 to ensure that the scraping thickness of the scraper 430 on various parts of the gas cylinder 600 is consistent. The scraper 430 can deflect relative to the blade holder 420 to adapt to the curvature changes at the mouth and bottom of the gas cylinder 600.

[0025] It is worth noting that, through the cooperation of the guide plate 510, the guide rod 570, and the counterweight 440, when the scraper 430 moves along the axial direction of the gas cylinder 600, the guide rod 570 slides along the upper contour line of the guide plate 510, driving the mounting platform 410 to automatically move radially up and down along the vertical guide rail 550, so that the gap between the scraper 430 and the surface of the gas cylinder 600 changes with the contour of the gas cylinder, thereby ensuring that the scraping thickness is completely consistent in both the cylinder body section and the irregular end cap section, fundamentally improving the interlayer uniformity and dimensional accuracy of the gas cylinder winding layer; The scraper 430 is rotatably mounted on the blade holder 420. In areas where the curvature changes drastically, such as the mouth and bottom of the gas cylinder 600, the scraper 430 can automatically deflect the angle according to the normal direction of the contact point, always maintaining the best cutting posture and adhering to the surface of the cylinder. This avoids the cutting angle deviation caused by the rigid scraper on the curved surface, prevents new damage caused by the interference between the scraper 430 and the fiber bundle, and ensures the smoothness and consistency of the scraping action throughout the entire length of the gas cylinder. The counterweight 440 is not only designed to drive the mounting platform 410 to descend, but also to create a constant pressure scraping system. Through the gravity of the counterweight 440, the scraper 430 adheres to the surface of the gas cylinder 600 with a relatively constant and controllable pressure, avoiding pressure fluctuations or rigid impacts. At the same time, it allows the scraper 430 to have a slight lifting capacity when encountering fiber hairs or small protrusions, thus playing a role in flexible protection.

[0026] Furthermore, please refer to Figure 7 The traction component 580 includes a traction shaft 581 rotatably mounted at both ends of the frame 100, a traction wheel 582 mounted on the traction shaft 581, a traction belt 583 connected between the two traction wheels 582, and a transverse traction platform 530 fixed to the traction belt 583; a first bevel gear 584 is provided on one end of the traction shaft 581, and a second bevel gear 585 meshing with the first bevel gear 584 is provided on the drive shaft 220; Specifically, when the rotary drive motor 210 drives the gas cylinder 600 to rotate circumferentially, it can synchronously drive the traction shaft 581 to rotate under the meshing transmission of the second bevel gear 585 and the first bevel gear 584, and then use the traction belt 583 to synchronously pull the transverse traction table 530 to move laterally, so as to realize the coordinated movement of the scraping unit 400 and the gas cylinder 600. In practical applications, the transmission ratio of the traction component 580 can be preset to ensure that the scraping range of the scraper 430 can cover the entire body of the gas cylinder 600.

[0027] It is worth noting that, through the meshing transmission of the first bevel gear 584 and the second bevel gear 585, the power of the rotary drive motor 210 is directly diverted from the drive shaft 220 to the traction member 580, thus establishing a rigid transmission chain between the circumferential rotation of the gas cylinder 600 and the axial movement of the scraping unit 400. Through the transmission of bevel gear pair and traction belt 583, the rotation angle of gas cylinder 600 and the axial displacement of scraper 430 always maintain a strict correspondence. No matter how the rotation speed of gas cylinder 600 changes or whether it goes through a start-stop process, the position of scraper 430 always keeps in sync with the rotation phase of gas cylinder 600, so that the scraping trajectory and fiber thickness distribution of each gas cylinder 600 are highly consistent in mass production. In practical applications, by pre-designing and replacing the first bevel gear 584 and the second bevel gear 585 with different gear ratios, or by adjusting the diameter of the traction wheel 582, the transmission ratio of the traction component 580 can be easily changed, enabling the equipment to adapt to gas cylinders 600 with different lengths and different winding pitch requirements, and ensuring that the scraping range of the scraper 430 accurately covers the entire cylinder body.

[0028] In further embodiments, please refer to Figure 8 and Figure 10 A piston rod 311 is fixed inside the sleeve 310, and a piston cavity 321 is opened inside the movable telescopic rod 320. The piston rod 311 movably passes through the movable telescopic rod 320 and extends into the piston cavity 321. A top support spring 312 is also movably sleeved on one end of the piston rod 311 that extends out of the movable telescopic rod 320. Specifically, the movable telescopic rod 320 can move axially to extend and retract relative to the piston rod 311, and at the same time, the movable telescopic rod 320 can also rotate circumferentially relative to the sleeve 310; the top support spring 312 applies an axial thrust to the movable telescopic rod 320 to extend the movable telescopic rod 320, and the top support member 330 applies axial pressure to the mouth of the gas cylinder 600; when the gas cylinder 600 rotates circumferentially, the movable telescopic rod 320 also rotates synchronously with the gas cylinder 600 relative to the sleeve 310.

[0029] It should be noted that by applying a continuous axial thrust to the movable telescopic rod 320 through the top support spring 312, when the gas cylinder 600 expands due to heat or has a slight dimensional deviation, the movable telescopic rod 320 can automatically fine-tune by further compressing the top support spring 312, avoiding the risk of thermal stress concentration or crushing of the fiber layer in the bottle mouth area that may be caused by rigid clamping, and playing a dual role of overload protection and adaptive adjustment. By sliding the piston rod 311 and the piston chamber 321, the axial telescopic motion and the circumferential rotation motion are cleverly decoupled. The movable telescopic rod 320 can slide smoothly axially on the piston rod 311 to adapt to changes in the length of the gas cylinder, and can also rotate freely with the rotation of the gas cylinder 600. This ensures that the top support clamping unit 300 will not generate any additional torsional resistance or jamming when the gas cylinder 600 is rotating at high speed, making the rotation of the gas cylinder 600 more stable and smooth, and reducing the additional load on the rotary drive motor 210. The cooperation between the piston rod 311 and the piston chamber 321 not only provides telescopic guidance, but also ensures that the movable telescopic rod 320 always remains highly coaxial with the sleeve 310. This built-in guide structure ensures that the axial force applied by the top support 330 is precisely applied to the central axis of the gas cylinder 600, so that the gas cylinder 600 can be automatically aligned after clamping. The high-precision alignment ensures that the radial runout of the gas cylinder 600 is minimal when rotating, providing a stable reference for the subsequent precise glue scraping and winding processes.

[0030] Further, please refer to Figure 9The top support 330 includes an end 331. An axial sliding cavity 332 is formed at the end of the end 331 facing the gas cylinder 600. An axial pressure plate 333 is slidably embedded in the axial sliding cavity 332. Several return springs 337 abutting against the axial pressure plate 333 are provided within the axial sliding cavity 332. Several sets of radial sliding grooves 334 are also circumferentially formed within the end 331. Radial sliders 335 are slidably embedded within the radial sliding grooves 334. A connecting rod 336 is hinged between the radial sliders 335 and the axial pressure plate 333. A radial expansion rod 338 is rotatably mounted on the radial slider 335. An inner flexible bladder 3382 is provided at the end of the radial expansion rod 338 away from the radial slider 335. A sliding pin 339 is provided on the inner wall of the end 331. A strip-shaped sliding groove 3381 adapted to the sliding pin 339 is formed in the middle of the radial expansion rod 338. Specifically, when the movable telescopic rod 320 slides out from the sleeve 310, the end 331 axially approaches the gas cylinder 600 until the axial pressure plate 333 presses against the mouth of the gas cylinder 600. At the same time, the axial pressure plate 333 gradually retracts into the axial sliding cavity 332, thereby pushing the radial slider 335 to slide radially along the radial groove 334 through the connecting rod 336. This, in turn, causes the end of the radial expansion rod 338 located in the end 331 to swing towards the center, and the strip groove 3381... The relative sliding pin 339 adapts to sliding. Correspondingly, the end of the radial expansion rod 338 that extends into the gas cylinder 600 expands radially outward until the inner support flexible bladder 3382 is in tight contact with the inner wall of the gas cylinder 600. Thus, the gas cylinder 600 is further radially expanded and fixed by multiple sets of radially outer radial expansion rods 338. Combined with the axial pressure of the axial pressure plate 333, the clamping stability of the gas cylinder 600 with the top support clamping unit 300 and the gas cylinder rotation unit 200 is improved.

[0031] It should be noted that, through the linkage of the axial pressure plate 333, connecting rod 336, radial slider 335 and radial expansion rod 338, the axial pushing force of the movable telescopic rod 320 is converted into the axial pressing force on the mouth of the gas cylinder 600 and the radial expansion force on the inner wall. This allows the mouth of the gas cylinder 600 to be subjected to both axial pressure and radial support at the same time, which can effectively resist the complex torque and vibration generated during the winding process and ensure that the gas cylinder 600 remains absolutely stable under high-speed rotation without any shaking or displacement. The axial pressure plate 333 is floatingly mounted in the axial sliding cavity 332 via a return spring 337, allowing it to self-adjust and finely adjust when contacting the bottle mouth end face, ensuring uniform distribution of the clamping force. At the same time, multiple sets of radial expansion rods 338 move synchronously under the drive of the connecting rod 336, applying a uniform expansion force to the inner wall of the bottle mouth from the circumferential direction, automatically correcting the center of the bottle mouth of the gas cylinder 600 to coincide with the rotation axis of the top support 330. This adaptive floating centering mechanism effectively eliminates the eccentricity problem caused by the manufacturing tolerance of the gas cylinder 600, ensuring the coaxiality of the gas cylinder 600 during rotation, and providing ideal basic conditions for subsequent precision glue application. When the inner flexible bladder 3382 at the end of the radial expansion rod 338 comes into contact with the inner wall of the gas cylinder 600, it can produce elastic deformation and conform to the micro-irregular contour of the inner wall of the cylinder opening. When the radial expansion rod 338 continues to expand, the inner flexible bladder 3382 is flattened, and the rigid support behind it provides a strong radial support force.

[0032] Furthermore, please refer to Figure 10 , Figure 11 and Figure 12 The movable telescopic rod 320 has a jet air passage 322 that communicates with the piston chamber 321 through one end facing the top support 330; the sleeve 310 has a transition air chamber 313 at one end; and the movable telescopic rod 320 has a plurality of through holes 323 in the circumferential direction that communicate with the piston chamber 321 and the transition air chamber 313. The inflation component 340 includes an air storage chamber 341 disposed in the sleeve 310, an air inlet 342 is provided at the bottom of the air storage chamber 341, and an air pipe 343 is connected between the air inlet 342 and the transition air chamber 313. An inner partition ring 3311 is provided on the inner side of the end 331. An annular venting channel 3331 is formed between the inner partition ring 3311 and the axial pressure plate 333. A plurality of vent holes 3332 communicating with the annular venting channel 3331 are provided on the outer circumferential side of the axial pressure plate 333.

[0033] Specifically, as the movable telescopic rod 320 and the top support 330 rotate synchronously with the gas cylinder 600, external high-temperature gas is introduced into the gas storage chamber 341 through the air inlet 342. Then, the high-temperature gas enters the transition gas chamber 313 through the gas pipe 343. Next, the gas enters the piston chamber 321 through each through hole 323, and finally is continuously and at high speed injected into the gas cylinder 600 from the injection channel 322. The high-temperature gas is injected into the cylinder body from the axis of the gas cylinder 600, thereby pushing the cold air in the cylinder body radially outward. Finally, the cold air is discharged from the cylinder body through the outer annular vent channel 3331 and released from each vent hole 3332. The high-temperature gas continuously injected into the cylinder body diffuses from the center outward to heat the cylinder body, and then the heat exchange gas is released from the periphery.

[0034] It is worth noting that, through the cooperation of the through hole 323, the transition air chamber 313, and the air pipe 343 on the circumferential opening of the movable telescopic rod 320, as the movable telescopic rod 320 and the top support 330 rotate at high speed with the gas cylinder 600, the high-temperature gas can still be smoothly transported from the stationary gas storage chamber 341 to the rotating piston chamber 321, and finally ejected from the injection air passage 322, ensuring that the heating process and the scraping process can be carried out synchronously, continuously, and stably. High-temperature gas is injected into the cylinder at high speed through the jet channel 322 at the center of the cylinder 600. Using the jet principle, the cold air inside the cylinder is pushed radially outward, forming a forced thermal convection that spreads from the center to the surrounding area. After sufficient heat exchange with the inner wall of the cylinder, the gas is finally discharged from the annular drain channel 3331 and the vent hole 3332 around the cylinder opening. This avoids the generation of heating dead zones and makes the temperature rise of all parts of the cylinder 600 more uniform and rapid, providing a stable and uniform thermal environment for reducing the viscosity of the adhesive. The piston chamber 321 serves as both the space for telescopic movement and a temporary gas storage chamber; the movable telescopic rod 320 functions as both a force transmission component and a gas guide pipe; the axial pressure plate 333 is not only used for axial clamping, but its cooperation with the inner partition ring 3311 also forms a gas venting channel; by continuously injecting high-temperature gas, a forced thermal convection circulation is formed inside the gas cylinder 600, and the high-speed airflow continuously washes the inner wall of the cylinder, quickly carrying away the cold energy generated by fiber entanglement and adhesive curing reaction, while efficiently transferring heat to the cylinder body, which can significantly shorten the time for the gas cylinder 600 to reach the target temperature, allowing the adhesive to quickly heat up and reduce viscosity before entering the scraping area, thereby ensuring the continuous stability of the scraping effect; By continuously injecting high-temperature gas into the bottle and releasing it outwards, a slightly positive pressure environment is created inside the bottle. This not only facilitates the penetration of hot air into every corner but also effectively prevents external cold air or adhesive volatiles from flowing back into the bottle. At the same time, the continuous airflow can promptly carry away and expel any adhesive volatiles that may be present inside the bottle, preventing these substances from condensing or adhering to the inner wall of the bottle at high temperatures. This plays a self-cleaning role and ensures the cleanliness of the bottle's inner cavity.
