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, i.e., 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 to a metal gas cylinder of the same volume, making it more convenient to use in rescue situations or serious 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, wet winding is to impregnate the carbon fiber tape and then directly wind it 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, fill an appropriate volume of resin liquid into the resin impregnation bin and check the smooth operation of each station; start the tilter to work, make the gas cylinder in a rotating state, start the heating wire to work, make the fiber tape and resin liquid passing through it maintain appropriate toughness and viscosity, and continuously wind the fiber wire onto the gas cylinder along a predetermined path through the moving platform to form the gas cylinder; the carbon fiber winding device makes the drainage ball form a pressing effect on the upper part of the fiber wire, further enhancing the downward fluidity of the resin liquid, while avoiding the accumulation of resin liquid in the inner cavity of the inner cylinder and 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 process of flowing 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.

[0014] The restoring component includes: a second pressing block mounted within the arc-shaped plate, with transition surfaces provided on both sides of the second pressing block; a restoring cavity disposed between the first pressing block and the second pressing block; a recycling box disposed on the fixed frame; a flow pipe connecting the recycling box and the restoring cavity, with retaining shells provided at both ends of the arc-shaped plate, and a return pipe connecting the bottoms of the recycling box and the retaining shells.

[0017] The beneficial effects of the present invention are as follows: (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 multiple times from both sides, 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.

[0018] (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, so that the carbon fiber tape entering the shuttle groove is in a flat state, which is convenient for subsequent flat winding on the outer side of the gas cylinder.

[0019] (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, and the excess resin liquid can be extruded. In addition, the gaps between the wound carbon fiber tapes and between the carbon fiber tape and the gas cylinder are extruded to discharge the air between the gaps, enhancing the production quality of the gas cylinder; When the first extrusion block leaves the carbon fiber tape wound on 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 to some extent. At this time, the resin liquid in the recovery cavity 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.

[0020] (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, so that the carbon fiber tape bends 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.

[0026] 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"; The clamping and flipping mechanism 1 includes: a support frame 101, and the support frame 101 is arranged on the ground; a fixed seat 102, and the fixed seat 102 is arranged on the ground; a third rotation driving member 103, and the third rotation driving member 103 is installed on the support frame 101; a first clamping rod 104, and the first clamping rod 104 is installed at the output end of the third rotation driving member 103; a second clamping rod 105, and the second clamping rod 105 is rotatably arranged on the fixed seat 102.

[0027] 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, and the carbon fiber winding mechanism 2 transports the carbon fiber tape so that the carbon fiber tape is wound 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.

[0028] The carbon fiber winding mechanism 2 includes: an impregnation component 21 that fills the resin liquid into the gaps between the filaments of the carbon fiber tape; a correction component 22 that corrects the carbon fiber tape; a moving component 23 that drives the carbon fiber tape to move and wind it around the outer side of the gas cylinder. In addition, there is a unwinding component for unwinding and feeding the carbon fiber tape, which is a conventional technical means in this field and will not be described in detail here.

[0029] The impregnation component 21 includes: an impregnation tank 211; a reinforcing block 212 disposed inside the impregnation tank 211; a plurality of square grooves 2121 are formed in the reinforcing block 212; a bending pipe 213 installed on the reinforcing block 212, and the bending pipe 213 communicates with the square groove 2121; a circulation pump 214 disposed inside the impregnation tank 211, the circulation pump 214 is connected to the bending pipe 213 through a pipeline 215, a discharge pipe 216 is provided on the bending pipe 213, and a protective cover 210 is provided outside the impregnation tank 211.

[0030] The correction component 22 includes: a connecting frame 221 installed on the impregnation tank 211; a correction block 222 installed on the connecting frame 221, a plurality of arc-shaped pointed blocks 2221 are provided on the correction block 222, a plurality of shuttle grooves 2222 are formed in the correction block 222, and the arc-shaped pointed blocks 2221 correspond to the central position of the carbon fiber tape; a plurality of guide shafts 223 rotatably disposed inside the impregnation tank 211.

[0031] 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 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. 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.

[0032] The moving component 23 includes: a working frame 231; a first guide rail 232 provided on the working frame 231; a sliding frame 233 slidably provided on the first guide rail 232 (preferably driven by a cylinder); a conical shell 234 installed on the dipping tank 211, and the dipping tank 211 is provided on the sliding frame 233; a limiting post 235, with multiple limiting posts 235 provided on the dipping tank 211; an auxiliary frame 236 installed on the dipping tank 211; two rolling rods 237 provided on the auxiliary frame 236; an adjusting block 238 installed on the auxiliary frame 236, with multiple adjusting grooves 2381 opened in the adjusting block 238, and the adjusting grooves 2381 are curved; an adjusting rod 239 provided on the auxiliary frame 236, with multiple arc-shaped grooves 2391 opened 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.

[0033] In this embodiment, the carbon fiber tape enters the dipping tank 211 along the guiding 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.

[0034] It should be noted that: after the carbon fiber tape is transmitted along the adjusting groove 2381, it is micro-shaped through the arc-shaped groove 2391 on the adjusting rod 239, so that the carbon fiber tape is slightly bent downward (as Figure 15 shown). The carbon fiber tape that is slightly bent downward fits better on the curved surface of the gas cylinder, enhancing the carbon fiber winding effect.

[0035] Embodiment Two: As Figures 1 - 15 shown, the same or corresponding components as those in Embodiment One adopt the corresponding reference numerals in Embodiment One. For the sake of simplicity, only the differences from Embodiment One will be described below. The difference between this Embodiment Two and Embodiment One lies in: This embodiment further includes a strengthening mechanism 3, which enables the resin liquid to fully immerse into the wound carbon fiber tape; the strengthening mechanism 3 includes: a motion component 31; an extrusion component 32 that extrudes the wound carbon fiber tape; a restoration component 33 that enables the resin liquid to fill the gaps in the wound carbon fiber tape; and a compensation component 34 that assists the extrusion component 32.

[0036] The motion assembly 31 includes: a fixed frame 311; a second guide rail 312, which is installed on the fixed frame 311; a moving block 313, which is slidably arranged on the second guide rail 312; a lifting plate 314, which is slidably arranged inside the moving block 313; a connecting plate 315, which is installed on the lifting plate 314; a first linear driving member 316, which is installed on the connecting plate 315; and a motion block 317, which is installed at the output end of the first linear driving member 316.

[0037] 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 inside 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.

[0038] The extrusion assembly 32 includes: a groove 3171, which is opened inside the motion block 317; two rotating rods 321, which are rotatably arranged inside the groove 3171; an arc-shaped plate 322, which is installed on the rotating rods 321; a first extrusion block 323, which is installed inside the arc-shaped plate 322, and transition surfaces 320 are provided on both sides of the first extrusion block 323; a gear 324, which is installed on the rotating rod 321, and the two gears 324 are meshed; and a second rotating driving member 325, which is installed on the motion block 317, and the second rotating driving member 325 drives one of the rotating rods 321 to rotate.

[0039] The compensation assembly 34 includes: a third linear driving member 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 driving member 341, and 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.

[0040] In this embodiment, the third linear driving member 341 drives the compensation blocks 342 at both ends to move so that they are attached to the two ends of the gas cylinder (which has completed the winding process). The extrusion assembly 32 in the initial state is in an 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, and the second rotating driving member 325 drives one of the rotating rods 321 to rotate, and drives the two arc-shaped plates 322 to clamp outside the compensation block 342 through the two gears 324. The motion component 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, causing the resin liquid to fall into the retention shell 335, and transmitting the resin liquid to the recovery box 333 through the return pipe 336.

[0041] The recovery component 33 includes: a second extrusion block 331, which is installed inside the arc-shaped plate 322 and has transition surfaces 320 on both sides; 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, which connects the recovery box 333 and the recovery cavity 332. 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 connected through a return pipe 336.

[0042] In this embodiment, the recovery box 333 transmits the resin liquid to 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 squeezed, so that the air between the gaps is squeezed out, enhancing the production quality of the gas cylinder. It should be noted that: power pumps (preferably peristaltic pumps) are provided on the circulation pipe 334 and the return pipe 336. The power pump on the circulation pipe 334 can transmit the resin liquid in the recovery box 333 to the recovery cavity 332, and can also transmit the resin liquid in the recovery cavity 332 to the recovery box 333; the power pump on the return pipe 336 can transmit the resin liquid in the retention shell 335 to the recovery box 333 through the return pipe 336. 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 recovery cavity 332 (under the action of the recovery force) will quickly fill the recovered gaps, enabling the resin liquid to fully penetrate into the wound carbon fiber tape, improving the production quality of the gas cylinder. The second extrusion block 331 squeezes the resin liquid in the carbon fiber tape wound on the gas cylinder together again, squeezing 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 transmits the resin liquid in the recovery cavity 332 to the recovery box 333.

[0043] Working steps 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 transports the carbon fiber tape so that the carbon fiber tape is wound around the outer side of the gas cylinder; 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 outer side of the gas cylinder; 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; Step 3, resin impregnation and strengthening process: The carbon fiber tape enters the resin impregnation tank 211 along the guide shaft 223. The resin liquid in the resin impregnation tank 211 submerges the carbon fiber tape. The carbon fiber tape transports forward along the square groove 2121. The circulating pump 214 pumps the resin liquid in the resin impregnation 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 for the resin liquid to adhere to the carbon fiber tape and improves the production quality of the gas cylinder; Step 4, compensation extrusion process: The third linear driving member 341 drives the compensation blocks 342 at both ends to move so that they are in contact with both ends of the (gas cylinder that has completed the winding process); The extrusion assembly 32 in the initial state is in an unfolded state (as Figure 9 shown). The moving assembly 31 drives the unfolded extrusion assembly 32 to move to the outside of one of the compensation blocks 342. The second rotation driving member 325 drives one of the rotating 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; The moving 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 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 transported to the recovery tank 333 through the return pipe 336; Step Five, Recovery Process: The recovery tank 333 transfers the resin liquid to the recovery chamber 332 through the circulation pipe 334. 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 323 first extrudes the carbon fiber tape wound on the gas cylinder, which can extrude 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 to squeeze out the air in the gaps, enhancing the production quality of the gas cylinder. 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 recovery chamber 332 will quickly fill the recovered gaps, enabling the resin liquid to fully penetrate into the wound carbon fiber tape, improving the production quality of the gas cylinder. The second extrusion block 331 further extrudes the resin liquid in the carbon fiber tape wound on the gas cylinder together to squeeze out the excess resin liquid. Then, it 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, and the circulation pipe 334 transfers the resin liquid in the recovery chamber 332 to the recovery tank 333.

[0044] 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.
