Description

Technical Field

[0001] The present invention relates to the technical field of carbon fiber winding for gas cylinders, and particularly to an automatic production device for gas cylinders. Background Art

[0002] A carbon fiber bottle, namely a carbon fiber wound composite gas cylinder, has better performance than a metal gas cylinder. The working pressure of the gas cylinder is 30 Mpa, which increases the gas storage capacity. The weight is reduced by 50% compared with a metal gas cylinder of the same volume, making it more convenient to use in rescue situations or severe disasters in high-rise buildings or deep underground such as mines.

[0003] The fiber winding process is an important link in the preparation of hydrogen storage cylinders, mainly divided into wet winding, dry winding, and wet-dry winding. Among them, in wet winding, the carbon fiber tape is impregnated and then directly wound on the mandrel under the control of tensile stress. This method has low production cost and is the most common winding process.

[0004] Chinese Patent Application No. 2024100898761 discloses a carbon fiber winding device and method for gas cylinders. First, an appropriate volume of resin liquid is filled into the resin impregnation tank, and the smooth operation of each station is checked; the tilter is started to work to keep the gas cylinder in a rotating state, and the heating wire is started to work to keep the fiber tape and resin liquid passing through it with appropriate toughness and viscosity. The fiber wire is continuously wound onto the gas cylinder along a predetermined path through the moving platform to form the gas cylinder; the carbon fiber winding device makes the drain ball form a pressing effect on the upper part of the fiber wire, further enhancing the downward fluidity of the resin liquid, and at the same time avoiding the accumulation of resin liquid in the inner cavity of the inner cylinder, improving the smoothness during continuous operation.

[0005] This carbon fiber winding device uses a carbon fiber tape (or carbon fiber wire) for winding. The carbon fiber tape (or carbon fiber wire) is composed of multiple strands of fine silk threads wound together, and there are gaps between the silk threads. When the carbon fiber tape is immersed in the resin liquid, it is difficult for the resin liquid to fill the gaps between the silk threads, which is not conducive to the resin liquid adhering to the carbon fiber tape and affects the quality of the gas cylinder. Therefore, we propose an automatic carbon fiber winding production device for gas cylinders. Summary of the Invention

[0006] The purpose of the present invention is to provide an automatic production device for gas cylinders in view of the deficiencies of the prior art. The carbon fiber tape enters the resin impregnation tank along the guide shaft, and the resin liquid in the resin impregnation tank submerges the carbon fiber tape. The carbon fiber tape is transported forward along the square groove, and the circulation pump pumps the resin liquid in the resin impregnation tank into the bending pipe. During the flow along the bending pipe, the resin liquid will pass through the carbon fiber tape back and forth from both sides multiple times, so that the resin liquid fills the gaps between the silk threads of the carbon fiber tape, which is conducive to the resin liquid adhering to the carbon fiber tape and improves the production quality of the gas cylinder.

[0007] To achieve the above object, the present invention provides the following technical solutions:

[0008] An automatic production device for gas cylinders, comprising a clamping and flipping mechanism and a carbon fiber winding mechanism. The clamping and flipping mechanism clamps both ends of the gas cylinder and then drives the gas cylinder to flip, and the carbon fiber winding mechanism winds a carbon fiber tape around the outside of the gas cylinder.

[0009] The carbon fiber winding mechanism includes: an impregnating component that immerses the carbon fiber tape in a resin liquid so that the resin liquid fills the gaps between the filaments of the carbon fiber tape; a straightening component that straightens the carbon fiber tape; and a moving component that drives the carbon fiber tape to move so that it winds around the outside of the gas cylinder.

[0010] The impregnating component includes: an impregnating tank; a reinforcing block provided in the impregnating tank; a plurality of square grooves formed in the reinforcing block; a bending pipe installed on the reinforcing block and communicating with the square grooves; a circulation pump provided in the impregnating tank, the circulation pump being connected to the bending pipe through a pipeline, and a discharge pipe being provided on the bending pipe.

[0011] The straightening component includes: a connecting frame installed on the impregnating tank; a straightening block installed on the connecting frame, the straightening block being provided with a plurality of arc-shaped pointed blocks, a plurality of shuttle grooves being formed in the straightening block, and the arc-shaped pointed blocks corresponding to the central position of the carbon fiber tape; and a plurality of guide shafts rotatably provided in the impregnating tank.

[0012] The moving component includes: a working frame; a first guide rail provided on the working frame; a sliding frame slidably provided on the first guide rail; a conical shell installed on the impregnating tank, the impregnating tank being provided on the sliding frame; a plurality of limit posts provided on the impregnating tank; an auxiliary frame installed on the impregnating tank; two rolling rods provided on the auxiliary frame; an adjusting block installed on the auxiliary frame, a plurality of adjusting grooves being formed in the adjusting block, the adjusting grooves being curved; and an adjusting rod provided on the auxiliary frame, a plurality of arc-shaped grooves being formed in the adjusting rod.

[0013] The present invention further includes a strengthening mechanism that enables the resin liquid to fully penetrate into the wound carbon fiber tape. The strengthening mechanism includes: a motion component; an extrusion component that extrudes the wound carbon fiber tape; a restoration component that enables the resin liquid to fill the gaps in the wound carbon fiber tape; and a compensation component that assists the extrusion component.

[0014] The moving component includes: a fixed frame; a second guide rail installed on the fixed frame; a moving block slidably disposed on the second guide rail; a lifting plate slidably disposed within the moving block; a connecting plate installed on the lifting plate; a first linear driving member installed on the connecting plate; and a moving block installed at the output end of the first linear driving member.

[0015] The extrusion component includes: a groove formed in the moving block; two rotating rods rotatably disposed within the groove; an arc-shaped plate installed on the rotating rods; a first extrusion block installed within the arc-shaped plate, with transition surfaces provided on both sides of the first extrusion block; a gear installed on the rotating rod, and the two gears meshing with each other; and a second rotating driving member installed on the moving block, which drives one of the rotating rods to rotate.

[0016] The recovery component includes: a second extrusion block installed within the arc-shaped plate, with transition surfaces provided on both sides of the second extrusion block; a recovery cavity disposed between the first extrusion block and the second extrusion block; a recovery box disposed on the fixed frame; a circulation pipe connecting the recovery box and the recovery cavity, with retention shells provided at both ends of the arc-shaped plate, and a return pipe connecting the bottoms of the recovery box and the retention shells.

[0017] The clamping and flipping mechanism includes: a support frame disposed on the ground; a fixed seat disposed on the ground; a third rotating driving member installed on the support frame; a first clamping rod installed at the output end of the third rotating driving member; and a second clamping rod rotatably disposed on the fixed seat.

[0018] The compensation component includes: a third linear driving member installed on the support frame and the fixed seat; a compensation block installed at the output end of the third linear driving member, with one of the compensation blocks sleeved outside the first clamping rod and the other compensation block sleeved outside the second clamping rod.

[0019] The beneficial effects of the present invention are as follows:

[0020] (1) In the present invention, the carbon fiber tape enters the resin impregnation tank along the guide shaft. The resin liquid in the resin impregnation tank submerges the carbon fiber tape. The carbon fiber tape is transported forward along the square groove. The circulation pump pumps the resin liquid in the resin impregnation tank into the bending pipe. During the flow along the bending pipe, the resin liquid passes through the carbon fiber tape back and forth from both sides multiple times, filling the gaps between the filaments of the carbon fiber tape with the resin liquid, facilitating the adhesion of the resin liquid to the carbon fiber tape and improving the production quality of the gas cylinder.

[0021] (2) In the present invention, during the transmission of the carbon fiber tape, the carbon fiber tape enters the shuttle groove along the arc-shaped tip. The arc-shaped tip plays a role in guiding and correcting the bent and deformed carbon fiber tape, making the carbon fiber tape entering the shuttle groove in a flat state, which is convenient for subsequent flat winding on the outer side of the gas cylinder.

[0022] (3) In the present invention, the recovery tank transports the resin liquid to the recovery cavity through the circulation pipe. After the carbon fiber tape is wound around the outer side of the gas cylinder, there will be gaps between the wound carbon fiber tapes and between the carbon fiber tape and the gas cylinder. The first extrusion block first extrudes the carbon fiber tape wound on the gas cylinder, which can extrude the excess resin liquid. Additionally, it extrudes the gaps between the wound carbon fiber tapes and between the carbon fiber tape and the gas cylinder, squeezing out the air in the gaps and enhancing the production quality of the gas cylinder;

[0023] When the first extrusion block leaves the carbon fiber tape wound on the gas cylinder, due to the elasticity of the carbon fiber tape, the gaps between the wound carbon fiber tapes and between the carbon fiber tape and the gas cylinder will recover to some extent. At this time, the resin liquid in the recovery cavity will quickly fill the recovered gaps, enabling the resin liquid to fully penetrate into the wound carbon fiber tape and improving the production quality of the gas cylinder.

[0024] (4) In the present invention, after the carbon fiber tape is transported along the adjustment groove, it undergoes micro-shaping through the arc-shaped groove on the adjustment rod, causing the carbon fiber tape to bend slightly downward (as Figure 15 shown), and the carbon fiber tape that bends slightly downward fits better on the curved surface of the gas cylinder, enhancing the carbon fiber winding effect.

[0041] 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.

[0043] In addition, the terms "first" and "second" are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, "a plurality of" means two or more, unless otherwise specifically defined.

[0044] Embodiment 1: As Figures 1-15 shown, this embodiment provides an automatic production device for gas cylinders, including a clamping and flipping mechanism 1 and a carbon fiber winding mechanism 2. The clamping and flipping mechanism 1 clamps both ends of the gas cylinder and then drives the gas cylinder to flip, and the carbon fiber winding mechanism 2 winds the carbon fiber tape on the outer side of the gas cylinder. It should be noted that this embodiment can also be named "an automatic production device for carbon fiber winding of gas cylinders".

[0045] The clamping and flipping mechanism 1 includes: a support frame 101, the support frame 101 is arranged on the ground; a fixed seat 102, the fixed seat 102 is arranged on the ground; a third rotation driving member 103, the third rotation driving member 103 is installed on the support frame 101; a first clamping rod 104, the first clamping rod 104 is installed at the output end of the third rotation driving member 103; a second clamping rod 105, the second clamping rod 105 is rotatably arranged on the fixed seat 102.

[0046] In this embodiment, the gas cylinder is clamped on the clamping and flipping mechanism 1, specifically between the first clamping rod 104 and the second clamping rod 105. The third rotation driving member 103 drives the first clamping rod 104 and the second clamping rod 105 to rotate to drive the gas cylinder to rotate. The carbon fiber winding mechanism 2 transports the carbon fiber tape so that the carbon fiber tape winds on the outer side of the gas cylinder. The clamping and handling of the gas cylinder preferably use a robotic arm to improve the degree of automation.

[0047] The carbon fiber winding mechanism 2 includes: an impregnation component 21, the impregnation component 21 fills the resin liquid into the gaps between the filaments of the carbon fiber tape; a correction component 22, the correction component 22 corrects the carbon fiber tape; a moving component 23, the moving component 23 drives the carbon fiber tape to move so that it winds on the outer side of the gas cylinder. In addition, it also includes a pay-off component for paying off and feeding the carbon fiber tape, which is a conventional technical means in this field and will not be described in detail here.

[0048] The impregnation component 21 includes: an impregnation tank 211; a reinforcing block 212, the reinforcing block 212 is arranged in the impregnation tank 211; a plurality of square grooves 2121 are formed in the reinforcing block 212; a bending pipe 213, the bending pipe 213 is installed on the reinforcing block 212, and the bending pipe 213 communicates with the square grooves 2121; a circulation pump 214, the circulation pump 214 is arranged in the impregnation tank 211, the circulation pump 214 is communicated with the bending pipe 213 through a pipeline 215, a discharge pipe 216 is arranged on the bending pipe 213, and a protective cover 210 is arranged outside the impregnation tank 211.

[0049] The correction component 22 includes: a connecting frame 221, which is installed on the dipping tank 211; a correction block 222, which is installed on the connecting frame 221. The correction block 222 is provided with a plurality of arc-shaped pointed blocks 2221, and a plurality of shuttle grooves 2222 are formed in the correction block 222. The arc-shaped pointed blocks 2221 correspond to the central position of the carbon fiber tape; a guide shaft 223, and a plurality of guide shafts 223 are rotatably arranged in the dipping tank 211.

[0050] In this embodiment, during the transmission of the carbon fiber tape, the carbon fiber tape enters the shuttle groove 2222 along the arc-shaped pointed block 2221. The arc-shaped pointed block 2221 plays a role in guiding and correcting the bent and deformed carbon fiber tape, so that the carbon fiber tape entering the shuttle groove 2222 is in a flat state, which is convenient for subsequent flat winding on the outer side of the gas cylinder;

[0051] Specifically, as Figure 14 shown, the carbon fiber tape may bend upward or downward. After being guided and corrected by the arc-shaped pointed block 2221, the carbon fiber tape entering the shuttle groove 2222 is in a flat state.

[0052] The moving component 23 includes: a working frame 231; a first guide rail 232, which is arranged on the working frame 231; a sliding frame 233, which is slidably arranged on the first guide rail 232 (preferably driven by a cylinder); a conical shell 234, which is installed on the dipping tank 211, and the dipping tank 211 is arranged on the sliding frame 233; a limiting column 235, and a plurality of limiting columns 235 are arranged on the dipping tank 211; an auxiliary frame 236, which is installed on the dipping tank 211; two rolling rods 237, which are arranged on the auxiliary frame 236; an adjusting block 238, which is installed on the auxiliary frame 236, and a plurality of adjusting grooves 2381 are formed in the adjusting block 238. The adjusting grooves 2381 are curved; an adjusting rod 239, which is arranged on the auxiliary frame 236, and a plurality of arc-shaped grooves 2391 are formed in the adjusting rod 239. A heating wire can be arranged in the conical shell 234 to moderately heat the carbon fiber tape. The resin droplets on the carbon fiber tape fall on the auxiliary frame 236 and then flow back into the dipping tank 211.

[0053] In this embodiment, the carbon fiber tape enters the dipping tank 211 along the guide shaft 223. The resin liquid in the dipping tank 211 submerges the carbon fiber tape. The carbon fiber tape is transmitted forward along the square groove 2121. The circulating pump 214 pumps the resin liquid in the dipping tank 211 into the bending pipe 213. During the process of flowing along the bending pipe 213, the resin liquid will pass through the carbon fiber tape back and forth from both sides multiple times, so that the resin liquid fills the gaps between the filaments of the carbon fiber tape, which is beneficial to the adhesion of the resin liquid in the carbon fiber tape and improves the production quality of the gas cylinder.

[0054] It should be noted that: after the carbon fiber belt is transmitted along the adjustment groove 2381, it passes through the arc groove 2391 on the adjustment rod 239 for micro-shaping, so that the carbon fiber belt bends slightly downward (as Figure 15 shown), and the carbon fiber belt that bends slightly downward fits better on the curved surface of the gas cylinder, enhancing the carbon fiber winding effect.

[0055] Embodiment 2: As Figures 1-15 shown, the same or corresponding components as those in Embodiment 1 are provided with the corresponding reference numerals in Embodiment 1. For the sake of simplicity, only the differences from Embodiment 1 will be described below. The difference between this Embodiment 2 and Embodiment 1 lies in:

[0056] This embodiment further includes a strengthening mechanism 3, and the strengthening mechanism 3 enables the resin liquid to fully immerse into the wound carbon fiber belt; the strengthening mechanism 3 includes: a motion assembly 31; an extrusion assembly 32, and the extrusion assembly 32 extrudes the wound carbon fiber belt; a recovery assembly 33, and the recovery assembly 33 enables the resin liquid to fill the gaps between the wound carbon fiber belts; a compensation assembly 34, and the compensation assembly 34 assists the extrusion assembly 32.

[0057] The motion assembly 31 includes: a fixed frame 311; a second guide rail 312, and the second guide rail 312 is installed on the fixed frame 311; a moving block 313, and the moving block 313 is slidably arranged on the second guide rail 312; a lifting plate 314, and the lifting plate 314 is slidably arranged in the moving block 313; a connecting plate 315, and the connecting plate 315 is installed on the lifting plate 314; a first linear driving member 316, and the first linear driving member 316 is installed on the connecting plate 315; a motion block 317, and the motion block 317 is installed at the output end of the first linear driving member 316.

[0058] The motion assembly 31 can drive the extrusion assembly 32 to move along the X, Y, and Z directions. Specifically, the first linear driving member 316 drives the extrusion assembly 32 to move along the Y direction, the lifting plate 314 slides in the moving block 313 to drive the extrusion assembly 32 to move along the Z direction, and the moving block 313 moves on the second guide rail 312 to drive the extrusion assembly 32 to move along the X direction. This is a conventional technical means in the art and will not be described in detail here.

[0059] The extrusion assembly 32 includes: a groove 3171, and the groove 3171 is opened in the motion block 317; two rotating rods 321, and the two rotating rods 321 are rotatably arranged in the groove 3171; an arc plate 322, and the arc plate 322 is installed on the rotating rod 321; a first extrusion block 323, and the first extrusion block 323 is installed in the arc plate 322, and transition surfaces 320 are arranged on both sides of the first extrusion block 323; a gear 324, and the gear 324 is installed on the rotating rod 321, and the two gears 324 are meshed; a second rotary driving member 325, and the second rotary driving member 325 is installed on the motion block 317, and the second rotary driving member 325 drives one of the rotating rods 321 to rotate.

[0060] The compensation component 34 includes: a third linear drive 341, which is installed on the support frame 101 and the fixed seat 102; a compensation block 342, which is installed at the output end of the third linear drive 341. One of the compensation blocks 342 is sleeved outside the first clamping rod 104, and the other compensation block 342 is sleeved outside the second clamping rod 105.

[0061] In this embodiment, the third linear drive 341 drives the compensation blocks 342 at both ends to move so that they fit against the two ends of the gas cylinder (which has completed the winding process).

[0062] The extrusion component 32 in the initial state is in the unfolded state (as Figure 9 shown). The motion component 31 drives the unfolded extrusion component 32 to move to the outside of one of the compensation blocks 342. The second rotary drive 325 drives one of the rotary rods 321 to rotate, and through two gears 324, two arc-shaped plates 322 are driven to clamp outside the compensation block 342.

[0063] The motion component 31 drives the two clamped arc-shaped plates 322 to move along the gas cylinder (on which carbon fiber has been wound) from the compensation block 342. The first extrusion block 323 first extrudes the carbon fiber tape wound on the gas cylinder to squeeze out the excess resin liquid on the wound carbon fiber tape, so that the resin liquid falls into the retention shell 335, and the resin liquid is transmitted into the recovery box 333 through the return pipe 336.

[0064] The recovery component 33 includes: a second extrusion block 331, which is installed inside the arc-shaped plate 322, and transition surfaces 320 are provided on both sides of the second extrusion block 331; a recovery cavity 332, which is arranged between the first extrusion block 323 and the second extrusion block 331; a recovery box 333, which is arranged on the fixed frame 311; a circulation pipe 334, the recovery box 333 is connected to the recovery cavity 332 through the circulation pipe 334, retention shells 335 are provided at both ends of the arc-shaped plate 322, and the bottom of the recovery box 333 and the retention shell 335 are communicated through a return pipe 336.

[0065] In this embodiment, the recovery box 333 transmits the resin liquid into the recovery cavity 332 through the circulation pipe 334. After the carbon fiber tape is wound on the outside of the gas cylinder, there will be gaps between the wound carbon fiber tapes and between the carbon fiber tape and the gas cylinder. The first extrusion block 323 first extrudes the carbon fiber tape wound on the gas cylinder, which can squeeze out the excess resin liquid. In addition, the gaps between the wound carbon fiber tapes and between the carbon fiber tape and the gas cylinder are extruded to expel the air between the gaps, enhancing the production quality of the gas cylinder.

[0066] It should be noted that: a power pump (preferably a peristaltic pump) is provided on the circulation pipe 334 and the return pipe 336. The power pump on the circulation pipe 334 can transfer the resin liquid in the recovery tank 333 to the recovery chamber 332, or transfer the resin liquid in the recovery chamber 332 to the recovery tank 333; the power pump on the return pipe 336 can transfer the resin liquid in the retention shell 335 to the recovery tank 333 through the return pipe 336;

[0067] When the first extrusion block 323 leaves the carbon fiber tape wound around the gas cylinder, due to the certain elasticity of the carbon fiber tape, the gaps between the wound carbon fiber tapes and between the carbon fiber tape and the gas cylinder will recover somewhat. At this time (under the action of the restoring force), the resin liquid in the recovery chamber 332 will quickly fill the recovered gaps, so that the resin liquid fully immerses into the wound carbon fiber tape, improving the production quality of the gas cylinder;

[0068] The second extrusion block 331 squeezes the resin liquid in the carbon fiber tape wound around the gas cylinder together, squeezes out the excess resin liquid, and then drives the two clamped arc-shaped plates 322 to move along the outside of the gas cylinder wound with the carbon fiber tape to another compensation block 342, and the circulation pipe 334 transfers the resin liquid in the recovery chamber 332 to the recovery tank 333.

[0069] Working steps

[0070] Step 1, carbon fiber winding process: Clamp the gas cylinder on the clamping and flipping mechanism 1, specifically between the first clamping rod 104 and the second clamping rod 105; the third rotation driving member 103 drives the first clamping rod 104 and the second clamping rod 105 to rotate to drive the gas cylinder to rotate, and the carbon fiber winding mechanism 2 transfers the carbon fiber tape so that the carbon fiber tape is wound around the outside of the gas cylinder;

[0071] Step 2, correction process: During the transmission of the carbon fiber tape, the carbon fiber tape enters the shuttle groove 2222 along the arc-shaped sharp block 2221. The arc-shaped sharp block 2221 plays a role in guiding and correcting the bent and deformed carbon fiber tape, so that the carbon fiber tape entering the shuttle groove 2222 is in a flat state, which is convenient for subsequent flat winding on the outside of the gas cylinder;

[0072] Specifically as Figure 14 shown, the carbon fiber tape may bend upward or downward. After being guided and corrected by the arc-shaped sharp block 2221, the carbon fiber tape entering the shuttle groove 2222 is in a flat state;

[0073] Step 3. Impregnation enhancement process: The carbon fiber tape enters the impregnation tank 211 along the guide shaft 223. The resin liquid in the impregnation tank 211 submerges the carbon fiber tape. The carbon fiber tape is transported forward along the square groove 2121. The circulation pump 214 pumps the resin liquid in the impregnation tank 211 into the bending pipe 213. During the flow along the bending pipe 213, the resin liquid will pass through the carbon fiber tape back and forth from both sides multiple times, so that the resin liquid fills the gaps between the filaments of the carbon fiber tape, which is beneficial for the resin liquid to adhere to the carbon fiber tape and improves the production quality of the gas cylinder.

[0074] Step 4. Compensation extrusion process: The third linear drive 341 drives the compensation blocks 342 at both ends to move so that they fit against both ends of the (gas cylinder that has completed the winding process).

[0075] In the initial state, the extrusion assembly 32 is in the unfolded state (as Figure 9 shown). The motion assembly 31 drives the unfolded extrusion assembly 32 to move to the outside of one of the compensation blocks 342. The second rotary drive 325 drives one of the rotary rods 321 to rotate, and drives the two arc-shaped plates 322 to clamp on the outside of the compensation block 342 through the two gears 324.

[0076] The motion assembly 31 drives the two clamped arc-shaped plates 322 to move along the (carbon fiber-wound) gas cylinder from the compensation block 342. The first extrusion block 323 first extrudes the carbon fiber tape wound on the gas cylinder, squeezing out the excess resin liquid on the wound carbon fiber tape, so that the resin liquid falls into the retention shell 335, and the resin liquid is transported to the recovery tank 333 through the return pipe 336.

[0077] Step 5. Restoration process: The recovery tank 333 transports the resin liquid to the restoration chamber 332 through the circulation pipe 334. After the carbon fiber tape is wound around the outside of the gas cylinder, there will be gaps between the wound carbon fiber tapes and between the carbon fiber tape and the gas cylinder. The first extrusion block 323 first extrudes the carbon fiber tape wound on the gas cylinder, which can squeeze out the excess resin liquid. In addition, it extrudes the gaps between the wound carbon fiber tapes and between the carbon fiber tape and the gas cylinder, squeezing out the air in the gaps and enhancing the production quality of the gas cylinder.

[0078] When the first extrusion block 323 leaves the carbon fiber tape wound on the gas cylinder, due to the elasticity of the carbon fiber tape, the gaps between the wound carbon fiber tapes and between the carbon fiber tape and the gas cylinder will recover to some extent. At this time, the resin liquid in the restoration chamber 332 will quickly fill the restored gaps, so that the resin liquid fully immerses into the wound carbon fiber tape, improving the production quality of the gas cylinder.

[0079] The second extrusion block 331 further extrudes the resin liquid inside the carbon fiber tape wound around the gas cylinder together, squeezing out the excess resin liquid, and then drives the two clamped arc-shaped plates 322 to move along the outer side of the gas cylinder wound with the carbon fiber tape to another compensation block 342. The circulation pipe 334 transfers the resin liquid in the recovery cavity 332 to the recovery tank 333.

[0080] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
