Description

Technical Field

[0001] The present invention relates to the technical field of gas cylinder production and processing, and particularly to a carbon fiber winding device and method for gas cylinder production. Background Art

[0002] A gas cylinder refers to a type of movable pressure vessel with a bottle-shaped main structure, generally filled with gas. A gas cylinder wound with carbon fiber is called a carbon fiber wound composite gas cylinder, which has better performance than a metal gas cylinder. The working pressure of the gas cylinder is 30 Mpa, thereby increasing the gas storage capacity. The weight is reduced by 50% compared to a metal gas cylinder of the same volume, making it easier for users. It is more convenient to use in rescue situations or serious disasters in high-rise buildings or deep underground such as mines.

[0003] In the process of processing and producing carbon fiber wound composite gas cylinders, a winding device is required to wind carbon fiber on the gas cylinder. There are many problems with existing winding devices. For example, the patent with publication number CN117601410B discloses a carbon fiber winding device and method for gas cylinders, which includes a gas cylinder and fiber filaments. The gas cylinder is located on a placement board, and also includes a turnover machine. The turnover machine is fixedly installed at both front ends of the placement board. A sleeve shaft is rotatably installed on the turnover machine, and the gas cylinder is fixedly installed between the two sleeve shafts; a moving platform, the moving platform is located on one side of the placement board. The fixed part in the moving platform is fixedly connected to the placement board, and the moving part in the moving platform is movably installed on the fixed part, and the moving part can perform horizontal movement, vertical lifting and rotation movements at the same time; an impregnation tank, the impregnation tank is fixedly installed at the rear of the placement board, and the impregnation tank is filled with resin. A transition cylinder is fixedly installed on one side of the moving part close to the impregnation tank, and a transition plate is fixedly installed on the side of the moving part away from the impregnation tank. The fiber filaments enter from the impregnation tank, pass through the transition cylinder, the moving part and the transition plate in sequence, and then wind around the periphery of the gas cylinder.

[0004] The above-mentioned carbon fiber winding device for gas cylinders solves the problem that in the wet winding method, it is necessary to make the resin adhere to the fiber filaments. Since the resin is mostly a viscous liquid, during the traction movement of the fiber filaments, the resin often adheres excessively and causes additional adhesion loss, and resin dripping is likely to occur. And when the fiber filaments pass through the inner cavity of the impregnation tank containing resin, due to the viscosity of the resin, when the traction movement speed of the fiber filaments exceeds the flow healing speed of the resin, a large number of air bubbles often pour into the part where the fiber filaments enter the resin, and under the traction of the fiber filaments, they spread throughout the resin filling chamber. The entry of air bubbles often causes voids to form between the fiber filaments and the resin, resulting in local resin loss on the surface of the fiber filaments, making it difficult to control the ratio of carbon fiber and resin, and causing poor forming effect of the gas cylinder.

[0005] However, when the above-mentioned carbon fiber winding device for gas cylinders and the existing winding device are used in practice, some gas cylinders use flat carbon fiber tapes. When winding, multiple flat carbon fiber tapes need to be combined together for winding. In this process, the carbon fiber tapes need to be combed and then merged. Due to the combing process, wrinkles will appear in the carbon fiber tapes. In addition, when winding, there may be overlap between two adjacent carbon fiber tapes. These will affect the uniformity of the winding, thereby reducing the winding quality.

[0006] Therefore, a new carbon fiber winding device and method for producing gas cylinders can be used to solve the shortcomings of the existing technology. Summary of the Invention

[0021] The present invention also provides a method for carbon fiber winding of gas cylinders, including the above-mentioned carbon fiber winding equipment for gas cylinder production, and further including the following steps:

[0022] S1. The carbon fiber belt is in a flat shape and wound on a carbon fiber belt roller. The carbon fiber belt roller is stored in a carbon fiber belt storage box. The carbon fiber belt on the carbon fiber belt roller is pulled out and inserted into a resin box. The carbon fiber belt is soaked in the resin box so that the carbon fiber belt carries resin. A pressing unit is installed in the resin box for pressing the carbon fiber belt. A resin content sensor cooperating with the carbon fiber belt is installed on the top of the resin box for detecting the resin content on the carbon fiber belt.

[0023] S2. Then, the carbon fiber belt is pulled to make the carbon fiber belt pass through the lead wire component and lead the carbon fiber belt to the mounting plate. Then, the carbon fiber belt passes through the wire guiding component, the wire merging component, the stretching component, the tension control component, and the lapping control component in sequence. Since the wire merging component merges the diverging carbon fiber belts, the carbon fiber belt on the wire guiding component will bend at this time, and at this time, the wire guiding component will reduce the bending angle to avoid creases on the carbon fiber belt.

[0024] When the carbon fiber belt passes through the stretching component, the stretching component can stretch and smooth the wrinkled carbon fiber belt to prevent the carbon fiber belt from overlapping. Then, under the action of the tension control component, the tension during the winding of the carbon fiber belt is controlled. Finally, the lapping length between adjacent two carbon fiber belts is controlled by the lapping control component for the winding of different types of gas cylinders.

[0025] S3. During the winding process, first, the gas cylinder is clamped on the fixed frame by the clamping component, and then the moving frame is moved to lock the other end of the gas cylinder. Then, the gas cylinder is driven to rotate by the clamping component. Before the rotation process, the end of the integrated carbon fiber belt is pasted on the gas cylinder by an external device, and then the gas cylinder is rotated for winding.

[0026] During the winding process, the driving component drives the mounting frame to move, causing the tape delivery unit to move along the radial direction of the gas cylinder for radial winding.

[0027] After the radial winding is completed, the driving component drives the tape delivery unit to move back and forth repeatedly. During the repeated movement, the third motor is started. The driving end of the third motor drives the rotating cylinder to rotate through a gear set, and the rotation angle is controlled within 180 degrees, realizing the change of the angle of the rotating cylinder while moving horizontally, so as to perform cross winding on the gas cylinder.

[0028] Compared with the existing technology, the advantages of the present invention are as follows:

[0029] 1. When the carbon fiber winding equipment for gas cylinder production winds the carbon fiber tape, by arranging a wire guiding roller with an arc-shaped protrusion to guide the carbon fiber tape, it can not only play a good guiding role, but also effectively avoid the bending of the carbon fiber tape when it gathers, reduce the probability of the carbon fiber folding during transportation, provide a relatively flat carbon fiber tape for subsequent winding, be conducive to improving the winding quality, and make the carbon fiber tape on the gas cylinder more flat.

[0030] 2. When the carbon fiber winding equipment for gas cylinder production winds the carbon fiber tape, by arranging a wire merging component to make the scattered carbon fiber tapes gather towards the middle, and then cooperating with an extension component to flatten the originally folded carbon fiber tape, and controlling the winding tension of the carbon fiber tape through a tension control component after flattening, the winding becomes more uniform.

[0031] 3. When the carbon fiber winding equipment for gas cylinder production winds the carbon fiber tape, by arranging a lap joint control component, using the oval elastic ring and arc-shaped rubber ring in the lap joint control component to control the lap joint length between two adjacent carbon fiber tapes, it is applicable to the winding of different types of gas cylinders, and the applicable winding range is wider.

[0032] In summary, when the present invention winds the carbon fiber tape of the gas cylinder, it is not only applicable to columnar carbon fiber filaments, but also applicable to flat carbon fiber tapes. At the same time, when winding the carbon fiber tape, it can extend and flatten the wrinkled and overlapped carbon fiber tapes, and control the winding tension of the carbon fiber tape and the lap joint length between two adjacent carbon fiber tapes, making the winding more uniform and applicable to the winding of different types of gas cylinders.

Specific embodiments

[0051] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0052] Embodiment 1: Refer to Figure 1 , a carbon fiber winding device for gas cylinder production, including a winding frame 1 and a carbon fiber belt 14, further including a fixed frame 9 fixedly installed on the winding frame 1 and a moving frame 2 slidably installed on the winding frame 1, and a clamping assembly is installed between the fixed frame 9 and the moving frame 2;

[0053] The clamping assembly includes five groups of fixed clamps 5 rotatably installed on the fixed frame 9 and the moving frame 2. The fixed clamps 5 on the fixed frame 9 cooperate with the fixed clamps 5 on the moving frame 2. Two second motors 10 are fixedly installed on the fixed frame 9, and a driving end of each of the two second motors 10 is fixedly connected to the corresponding fixed clamp 5 installed on the fixed frame 9.

[0054] First, clamp the gas cylinder on the fixed clamp 5 on the fixed frame 9, then move the moving frame 2 so that the fixed clamp 5 on the moving frame 2 contacts the other end of the gas cylinder, and then clamp and fix the other end of the gas cylinder through this fixed clamp 5. After the fixation is completed, start the second motor 10. The rotation of the driving end of the second motor 10 will drive the fixed clamp 5 to rotate, thereby driving the gas cylinder to rotate.

[0055] The movement of the moving frame 2 can be achieved by an electric push rod, which is a common device in the prior art and is not shown in detail in the figure, nor will it be elaborated in detail in this application.

[0056] Embodiment 2: The difference between this embodiment and the technical solution of Embodiment 1 lies in that: referring to [[ID=3 , a carbon fiber tape storage box 3 for storing carbon fiber tapes 14 is fixedly installed on the winding machine frame 1. An installation frame 4 is slidably installed on the winding machine frame 1, and a driving assembly matched with the installation frame 4 is installed on the winding machine frame 1;

[0057] The driving assembly includes a first motor 7 fixedly installed on the winding machine frame 1. A lead screw 6 is rotatably installed on the winding machine frame 1. The driving end of the first motor 7 is fixedly connected to the lead screw 6. A threaded sleeve is rotationally installed on the lead screw 6 in a threaded manner, and the threaded sleeve is fixedly connected to the installation frame 4. Two circular holes are formed in the installation frame 4, and two limiting round rods matched with the corresponding circular holes are fixedly installed on the winding machine frame 1.

[0058] The driving end of the first motor 7 rotates to drive the lead screw 6 fixedly connected thereto to rotate. The rotation of the lead screw 6 drives the threaded sleeve to move on the lead screw 6, thereby driving the installation frame 4 to move. Since the rotation of the lead screw 6 will also drive the threaded sleeve to rotate under the action of friction, it is necessary to use the limiting round rod to limit the threaded sleeve to prevent the threaded sleeve from rotating. At this time, the threaded sleeve will slide on the limiting round rod. The first motor 7 is a bidirectional motor and can convert the rotation direction of the driving end at a fixed frequency, so as to realize the reciprocating movement of the installation frame 4.

[0059] Embodiment 3: The difference between this embodiment and the technical solution of Embodiment 2 lies in that: referring to ​ :

[0060] Referring to ​ , five tape-out units 8 are installed on the installation frame 4. The tape-out unit 8 includes a resin box 11. A rotating cylinder 13 is rotatably installed on the resin box 11. A third motor 16 is fixedly installed on the resin box 11; the rotating cylinder 13 is driven by a gear set 15 between the driving end of the third motor 16, and an installation plate 18 is fixedly installed on the rotating cylinder 13;

[0061] When the driving end of the third motor 16 rotates, it will drive the rotating cylinder 13 to rotate through the gear set 15. The rotation of the rotating cylinder 13 drives the mounting plate 18 fixedly connected thereto to rotate. The third motor 16 controls the rotation angle of its driving end through the control system, so as to realize the angle change of the mounting plate 18. At the same time, a vertical movement mechanism is installed on the mounting frame 4, which can drive the resin box 11 to move up and down. Since this movement mechanism is existing, it is not shown in detail in the drawings and will not be elaborated here either. It can be realized by a driving cylinder. While moving horizontally in one direction, the mounting plate 18 moves up or down. Then, after moving to the end of the gas cylinder, the horizontal movement direction and the vertical movement direction both change to realize cross winding.

[0062] A mounting plate 18 is fixedly installed on the rotating cylinder 13. A lead wire assembly 24 matched with the carbon fiber tape 14 is installed on the mounting plate 18. The lead wire assembly 24 includes a bracket fixedly installed on the mounting plate 18. A horizontally arranged rotating rod is rotatably installed on the bracket, and a plurality of vertically arranged rods are rotatably installed on the bracket at equal intervals for pulling the carbon fiber tape 14 from the resin box 11 onto the mounting plate 18.

[0063] Lay the carbon fiber tape 14 on the rotating rod, and place multiple carbon fiber tapes 14 between adjacent two vertical rods respectively. The gap between adjacent two vertical rods is equal to the width of the carbon fiber tape 14, so as to limit the carbon fiber tape 14 and prevent the carbon fiber tape 14 from running off.

[0064] A diversion groove is formed on the mounting plate 18 for collecting the resin dripping from the carbon fiber tape 14. The mounting plate 18 is at a moving backward inclination angle, so that the resin dripping into the diversion groove can automatically flow into the resin box 11 for collection and reuse.

[0065] Refer to ​ 、 ​ As shown in, the wire assembly 19, the wire assembly 19 includes a frame body one 26 fixedly installed on the mounting plate 18. A horizontally arranged rotating roller 27 is rotatably installed on the frame body one 26, and a plurality of wire rollers 28 are rotatably installed on the frame body one 26 at equal intervals. Each wire roller 28 is provided with a protrusion. The joint of the protrusion and the wire roller 28 is designed as an arc, and the bottom of the protrusion is flush with the top of the rotating roller 27.

[0066] Since the carbon fiber tape 14 is placed horizontally on the rotating roller 27, the wire roller 28 is perpendicular to the rotating roller 27, and the carbon fiber tape 14 will bend laterally between the two wire rollers 28. If there is no bulge designed here, when the wire roller 28 is perpendicular to the rotating roller 27, the angle between the two is ninety degrees, and the side of the carbon fiber tape 14 will directly contact the wire roller 28, which will cause the carbon fiber tape 14 to wrinkle or even fold. However, the bulge is designed here. Once the side of the carbon fiber tape 14 contacts the wire roller 28, the carbon fiber tape 14 will move along the bulge, so that the carbon fiber tape 14 is close to the bulge position. This can effectively avoid wrinkling or folding of the carbon fiber tape 14, providing a favorable foundation for subsequent winding (such as ​ shown).

[0067] Reference ​ 、 ​ , the parallel line component 20, the parallel line component 20 includes a frame 29 fixedly mounted on the mounting plate 18, and two horizontal limiting rollers 30 distributed up and down are rotatably mounted on the frame 29, and two lateral limiting rollers 31 located on both sides of the frame 29 are rotatably mounted on the frame 29.

[0068] When the carbon fiber tape 14 is inserted between the two horizontal limiting rollers 30, it will be limited by the lateral limiting rollers 31 on both sides to gather towards the middle, so as to realize the retraction of the carbon fiber tape 14;

[0069] The design effect is the same as the above-mentioned wire roller 28. Due to the arrangement of the lateral limiting roller 31 and the horizontal limiting roller 30, when the carbon fiber tape 14 is gathered, the carbon fiber tape 14 will be wrinkled or folded at the connection between the horizontal limiting roller 30 and the lateral limiting roller 31. At this time, the ends of the lateral limiting roller 31 and the horizontal limiting roller 30 are both arc-shaped. The two lateral limiting rollers 31 and the two horizontal limiting rollers 30 form a rectangle, and the inner corners of the rectangle are arc-shaped. In this way, the carbon fiber tape 14 will stick to the arc-shaped part, which can effectively avoid the wrinkles and folds of the carbon fiber tape 14 (such as ​ shown).

[0070] Reference ​ 、 ​ , extension component 21, the extension component 21 includes a frame three 32 fixedly mounted on the mounting plate 18, a mouth-shaped shaft is fixedly mounted on the frame three 32, a plurality of baffles 33 are fixedly mounted on the upper part of the shaft, two adjustment frames are fixedly mounted on the upper part of the shaft, a rotating shaft is rotatably mounted on the adjusting frame, each baffle 33 is provided with a hole for the movement of the rotating shaft, multiple groups of upper spiral rubber rod groups 34 are rotatably mounted on the upper part of the shaft, and multiple groups of lower spiral rubber rod groups 36 are rotatably mounted on the rotating shaft, each group of upper spiral rubber rod groups 34 and lower spiral rubber rod groups 36 are located between two adjacent baffles 33, and each group of upper spiral rubber rod groups 34 and lower spiral rubber rod groups 36 are composed of two spiral rubber rods with opposite spiral directions;

[0071] A pressure adjusting mechanism 35 matched with the rotating shaft is installed on the adjusting frame. The pressure adjusting mechanism 35 includes a nut fixedly installed on the adjusting frame, a screw rod is rotationally installed on the nut in a threaded manner, a slider is slidably installed on the adjusting frame, the screw rod is rotatably connected to the slider, and the rotating shaft is rotatably connected to the slider.

[0072] Insert the carbon fiber belt 14 between the two baffles 33, make the carbon fiber belt 14 abut against the upper spiral rubber rod group 34, and then rotate the two screw rods simultaneously. There is a situation where the screw rods may get stuck due to asynchronous rotation, so intermittent adjustment from left to right is required. There is a certain gap between the slider and the adjusting frame for adjustment. Under the action of the nut, the slider is driven to move, and the movement of the slider drives the movement of the rotating shaft, so that the lower spiral rubber rod group 36 on the rotating shaft abuts against the bottom of the carbon fiber belt 14, and the lower spiral rubber rod group 36 and the upper spiral rubber rod group 34 clamp the carbon fiber belt 14;

[0073] After clamping, as the carbon fiber belt 14 moves between the lower spiral rubber rod group 36 and the upper spiral rubber rod group 34, it will drive the rotation of the spiral rubber rods on the lower spiral rubber rod group 36 and the upper spiral rubber rod group 34 under the action of friction. Since the spiral rubber rods are spiral-shaped, and the spiral directions of the two spiral rubber rods of the lower spiral rubber rod group 36 and the upper spiral rubber rod group 34 are opposite, and the spiral directions of the upper and lower corresponding spiral rubber rods are the same. In this way, during the rotation of the spiral rubber rods, the carbon fiber belt 14 will be unfolded under the action of friction, so that the carbon fiber belt 14 can be extended and laid out;

[0074] Since the carbon fiber belt 14 is folded as a whole and not folded in segments, the width of the folded carbon fiber belt 14 is smaller than the width of the carbon fiber belt 14 when it is normally unfolded. At this time, it is necessary to push the carbon fiber belt 14 between the two cooperating spiral rubber rods according to the folding direction of the carbon fiber belt 14. The width of each spiral rubber rod is equal to the width of the carbon fiber belt 14. The specific operation is as follows: The carbon fiber belt 14 is clamped between the upper and lower spiral rubber rods. Since the spiral directions of the upper and lower spiral rubber rods are the same but the rotation directions are opposite, the spiral rubber rod at the bottom will drive the lower folded section of the folded carbon fiber belt 14 to move towards the side close to the baffle 33 under the action of friction, while the spiral rubber rod at the upper part will drive the upper folded section of the carbon fiber belt 14 to move away from the side of the baffle 33 under the action of friction, so as to unfold the carbon fiber belt 14.

[0075] The thickness of the baffle 33 is 1 mm, which can reduce the distance between adjacent two carbon fiber belts 14, so as to facilitate more accurate adjustment of the overlapping length of the carbon fiber belt 14 in the follow-up.

[0076] Refer to ​ 、 ​, the tension control component 22, the tension control component 22 includes a frame body 37 fixedly mounted on the mounting plate 18, two sliding blocks are slidably mounted on the frame body 37, a plurality of elastic telescopic rods 41 are fixedly mounted between the two sliding blocks and the frame body 37, a pressure roller 38 is rotatably mounted on the two sliding blocks, a resistance roller 39 that cooperates with the pressure roller 38 is rotatably mounted on the frame body 37, and a resistance controller 40 that cooperates with the resistance roller 39 is fixedly mounted on the frame body 37.

[0077] When the unfolded carbon fiber tape 14 passes through the resistance roller 39 and the pressure roller 38, the elastic telescopic rod 41 will cause the pressure roller 38 to resist the carbon fiber tape 14, and cooperate with the resistance roller 39 to clamp the carbon fiber tape 14. As the carbon fiber tape 14 moves, the resistance roller 39 and the pressure roller 38 will be driven to rotate by the moving friction of the carbon fiber tape 14. At this time, the resistance of the resistance roller 39 during rotation is controlled by the resistance controller 40, thereby changing the friction force required for the carbon fiber tape 14 to drive the resistance roller 39 to rotate. The greater the friction force, the greater the resistance to the movement of the carbon fiber tape 14 and the greater the tension.

[0078] Here, the resistance roller 39 and the pressure roller 38 also have the function of gathering the carbon fiber tape 14, because after passing through the extension component 21, there is a certain distance between the two adjacent carbon fiber tapes 14, but because the distance is small, the bending force on both sides of the carbon fiber tape 14 is small, and it will not cause folding, but wrinkles will occur. The wrinkles will not appear until the carbon fiber tape 14 passes through between the pressure roller 38 and the resistance roller 39 and can automatically unfold.

[0079] Reference ​ 、 ​ , the overlap control component 23, the overlap control component 23 includes an electric clamp 42 fixedly mounted on the bottom of the mounting plate 18, and a side arm 43 is fixedly mounted on each of the two clamping jaws of the electric clamp 42, and an elastic ring 44 is fixedly mounted between the two side arms 43, and two arc-shaped rubber rings 46 that match the carbon fiber belt 14 are fixedly mounted on the elastic ring 44, and a lateral correction auxiliary spring 45 is fixedly mounted inside the elastic ring 44, and a sliding rod 47 is fixedly mounted on one of the side arms 43, and the sliding rod 47 passes through the elastic ring 44 and passes through the inside of the correction auxiliary spring 45.

[0080] A steering roller 25 is rotatably mounted at the end of the mounting plate 18 to change the direction of the carbon fiber tape 14. At the same time, the height of the elastic ring 44 is lower than the steering roller 25, which ensures that the carbon fiber tape 14 is straight.

[0081] When the carbon fiber tape 14 is attached to the rubber ring 46, the carbon fiber tape 14 is tilted due to the arc-shaped rubber ring 46. As the carbon fiber tape 14 moves, the carbon fiber tapes 14 on both sides move toward the middle, which can reduce the distance between the two carbon fiber tapes 14.

[0082] The degree of spacing reduction is related to the arc of the elastic ring 44. The larger the arc, the more the distance is reduced. Therefore, the arc of the elastic ring 44 is controlled according to the width to be lapped (the change in the arc of the elastic ring 44 will drive the change in the arc of the rubber ring 46). The specific operation is as follows:

[0083] The electric gripper 42 drives the side arms 43 on both sides to move, thus squeezing the elastic ring 44 towards the middle or stretching it towards both sides to deform the elastic ring 44 (the elastic ring 44 is oval and has a certain self - resetting elastic force. The elastic ring 44 is made of a spring piece with a certain resetting elasticity). In this way, the arc at the top of the elastic ring 44 can be changed;

[0084] The function of setting the correction auxiliary spring 45 is to assist the reset of the elastic ring 44, thereby reducing the probability of deformation of the elastic ring 44. The function of the sliding rod 47 is to limit the correction auxiliary spring 45 to ensure that the correction auxiliary spring 45 is straight.

[0085] The specific operation steps of this device are as follows:

[0086] The carbon fiber tape 14 is flat and wound around the carbon fiber tape roller. The carbon fiber tape roller is stored in the carbon fiber tape storage box 3. The carbon fiber tape 14 on the carbon fiber tape roller is pulled out and inserted into the resin box 11. The carbon fiber tape 14 is soaked in the resin box 11 so that the carbon fiber tape 14 carries resin. A pressing unit is installed in the resin box 11 for pressing the carbon fiber tape 14. A resin content sensor 12 matching the carbon fiber tape 14 is installed on the top of the resin box 11 for detecting the resin content on the carbon fiber tape 14;

[0087] Then, the carbon fiber tape 14 is pulled, so that the carbon fiber tape 14 passes through the lead - wire assembly 24 and is led to the mounting plate 18. Then, the carbon fiber tape 14 passes through the wire assembly 19, the wire - merging assembly 20, the extension assembly 21, the tension control assembly 22, and the lapping control assembly 23 in sequence. Since the wire - merging assembly 20 merges the divergent carbon fiber tapes 14, the carbon fiber tape 14 on the wire assembly 19 will bend at this time, and at this time, the wire assembly 19 will reduce the bending angle to avoid creases on the carbon fiber tape 14;

[0088] When the carbon fiber tape 14 passes through the extension assembly 21, the extension assembly 21 can flatten the wrinkled carbon fiber tape 14 to prevent the carbon fiber tape 14 from overlapping. Then, under the action of the tension control assembly 22, the tension during the winding of the carbon fiber tape 14 is controlled. Finally, the lapping length between two adjacent carbon fiber tapes 14 is controlled by the lapping control assembly 23 for the winding of different types of gas cylinders.

[0089] During the winding process, first, the gas cylinder is clamped on the fixing frame 9 by the clamping assembly, then the moving frame 2 is moved to lock the other end of the gas cylinder, and then the gas cylinder is driven to rotate by the clamping assembly. Before the rotation process, the end of the integrated carbon fiber tape 14 is pasted on the gas cylinder by an external device, and then the gas cylinder is rotated for winding;

[0090] During the winding process, the mounting frame 4 is driven to move by the driving assembly, so that the tape feeding unit 8 moves along the radial direction of the gas cylinder for radial winding;

[0091] After the radial winding is completed, the tape feeding unit 8 is driven to move back and forth repeatedly by the driving assembly. During the repeated movement, the third motor 16 is started. The driving end of the third motor 16 drives the rotating cylinder 13 to rotate through the gear set 15, and the rotation angle is controlled within 180 degrees, so as to change the angle of the rotating cylinder 13 while realizing the horizontal movement, thereby performing cross winding on the gas cylinder.

[0092] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.

The carbon fiber tape (14) is flat and wound around a carbon fiber tape roller, which is stored in a carbon fiber tape storage box (3). The carbon fiber tape (14) on the carbon fiber tape roller is pulled out and inserted into a resin box (11). The carbon fiber tape (14) is soaked in the resin box (11) so that the carbon fiber tape (14) carries resin.

A resin content sensor (12) matching the carbon fiber tape (14) is installed on the top of the resin box (11) for detecting the resin content on the carbon fiber tape (14). S2. Then, the carbon fiber tape (14) is pulled to make the carbon fiber tape (14) pass through a lead wire assembly (24), and the carbon fiber tape (14) is led to a mounting plate (18). Then, the carbon fiber tape (14) passes through a wire assembly (19), a wire merging assembly (20), a stretching assembly (21), a tension control assembly (22), and a lap joint control assembly (23) in sequence. Since the wire merging assembly (20) merges the divergent carbon fiber tapes (14), the carbon fiber tape (14) on the wire assembly (19) will be bent at this time, and at this time, the wire assembly (19) will reduce the bending angle to avoid creases on the carbon fiber tape (14).

During the winding process, the mounting frame (4) is driven to move by a driving assembly, so that the tape output unit (8) moves along the radial direction of the gas cylinder for radial winding. After the radial winding is completed, the driving assembly drives the tape output unit (8) to move back and forth repeatedly. During the repeated movement, the third motor (16) is started. The driving end of the third motor (16) drives the rotating cylinder (13) to rotate through a gear set (15), and the rotation angle is controlled within one hundred and eighty degrees, so that the angle of the rotating cylinder (13) changes while realizing the horizontal movement, thereby performing cross winding on the gas cylinder.
