In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0054] Please refer to Figures 1-16 , this embodiment provides a carbon fiber tube winding device, which is used to replace manual labor to wind a carbon fiber tube on the mandrel 1, so as to improve the working efficiency of winding the carbon fiber tube, and further improve the production efficiency of the carbon fiber tube.

[0055] Specifically, the carbon fiber tube winding device includes a clamping module and a rotating mechanism 32. Among them, the clamping module includes a first clamping sleeve 311 and a second clamping sleeve 312 arranged at intervals along the first horizontal direction. The first clamping sleeve 311 and the second clamping sleeve 312 can respectively clamp both ends of the mandrel 1, and the mandrel 1 is placed in a posture parallel to the first horizontal direction.

[0056] The rotating mechanism 32 includes a rotating shaft and a first driving member 322. The axis of the rotating shaft extends along the first horizontal direction, and the rotating shaft includes a first shaft portion 3211 and a second shaft portion 3212 arranged at intervals along the first horizontal direction. Among them, the first clamping sleeve 311 is sleeved on the outer periphery of the first shaft portion 3211, the second clamping sleeve 312 is sleeved on the outer periphery of the second shaft portion 3212, and the first driving member 322 is configured to drive the clamping module to rotate around the axis of the rotating shaft, that is, the first driving member 322 is configured to drive the first clamping sleeve 311 and the second clamping sleeve 312 to rotate around the axis of the rotating shaft, and further drive the mandrel 1 to rotate around the axis of the rotating shaft.

[0057] In addition, in addition to the clamping module and the rotating mechanism 32, the carbon fiber tube rolling equipment further includes a pressing module 33. The pressing module 33 includes a roller 331 and a driving module 332. The roller 331 and the rotating shaft are arranged at intervals in the vertical direction, and the axis of the roller 331 extends along the first horizontal direction. The driving module 332 is configured to drive the roller 331 to move towards the clamping module and can keep the roller 331 pressing against the top of the mandrel 1 in the vertical direction. Moreover, it can be understood that the pressing module 33 further includes a first mounting bracket 333, and the roller 331 is rotatably connected to the first mounting bracket 333, so as to roll the carbon fiber composite fabric 2.

[0058] Specifically, in this embodiment, the mandrel 1 is clamped between the first jacket 311 and the second jacket 312. The carbon fiber composite fabric 2 can be placed on the top of the mandrel 1, and the roller 331 can press the carbon fiber composite fabric 2 against the top of the mandrel 1. Then, the first driving member 322 drives the first jacket 311 and the second jacket 312 to rotate around the axis of the rotating shaft, thereby driving the mandrel 1 to rotate around the axis of the rotating shaft. During the rotation of the mandrel 1, the carbon fiber composite fabric 2 is gradually wound around the outer periphery of the mandrel 1. Moreover, during the rotation of the mandrel 1, each part of the mandrel 1 along its circumferential direction will successively become the top of the mandrel 1. Since the roller 331 always keeps pressing against the top of the mandrel 1, during the rotation of the mandrel 1, the roller 331 can continuously roll the carbon fiber composite fabric 2 to ensure that the carbon fiber composite fabric 2 is evenly and flatly wound around the outer periphery of the mandrel 1, thereby preventing problems such as uneven forming of the carbon fiber tube and wrinkles in the carbon fiber composite fabric 2, and further ensuring that the performance of the produced carbon fiber tube meets the requirements.

[0059] After the carbon fiber composite fabric 2 is wound around the outer periphery of the mandrel 1 and a carbon fiber tube is formed, the mandrel 1 is removed from between the first jacket 311 and the second jacket 312, so that the carbon fiber tube can be subsequently removed from the mandrel 1.

[0060] As described above, in this embodiment, the mandrel 1 is clamped by the first jacket 311 and the second jacket 312, and the first jacket 311 and the second jacket 312 can drive the mandrel 1 to rotate, so as to wind the carbon fiber composite fabric 2 around the outer periphery of the mandrel 1 to produce a carbon fiber tube. In addition, in this embodiment, the roller 331 rolls the carbon fiber composite fabric 2 during the winding process of the carbon fiber composite fabric 2 to ensure that the carbon fiber composite fabric 2 is evenly and flatly wound around the outer periphery of the mandrel 1, thereby preventing problems such as uneven forming of the carbon fiber tube and wrinkles in the carbon fiber composite fabric 2, and further ensuring that the performance of the produced carbon fiber tube meets the requirements.

[0061] It should be noted that in this embodiment, the first driving member 322 first drives the clamping module to rotate clockwise along the axis of the rotating shaft, and then after the clamping module to be clamped rotates counterclockwise along the axis of the rotating shaft and resets, it drives the clamping module to continue rotating counterclockwise along the axis of the rotating shaft, so as to wind the carbon fiber composite material cloth 2 around the outer periphery of the mandrel 1. Of course, in other alternative embodiments, the first driving member 322 can also drive the clamping module to rotate clockwise along the axis of the rotating shaft, so as to wind the carbon fiber composite material cloth 2 around the outer periphery of the mandrel 1, or the first driving member 322 can also drive the clamping module to rotate counterclockwise along the axis of the rotating shaft, so as to wind the carbon fiber composite material cloth 2 around the outer periphery of the mandrel 1. This embodiment does not make specific limitations on this.

[0062] Based on the above-mentioned content, in this embodiment, the first jacket 311 is provided with a first through hole 3111 along the first horizontal direction. The first through hole 3111 includes a first hole portion 31111 and a second hole portion 31112. Exemplarily, in this embodiment, the first hole portion 31111 and the second hole portion 31112 are coaxial. Among them, the first hole portion 31111 is located on the side of the first jacket 311 facing the second jacket 312 and is adapted to one end of the mandrel 1. That is, in this embodiment, the first hole portion 31111 is a profiling hole, and one end of the mandrel 1 can be inserted into the first hole portion 31111.

[0063] The second hole portion 31112 is located on the side of the first hole portion 31111 away from the second jacket 312. The first jacket 311 is sleeved on the outer periphery of the first shaft portion 3211 through the second hole portion 31112.

[0064] Correspondingly, the second jacket 312 is provided with a second through hole 3121 along the first horizontal direction. The second through hole 3121 includes a third hole portion 31211 and a fourth hole portion 31212. Exemplarily, in this embodiment, the third hole portion 31211 and the fourth hole portion 31212 are coaxial. The third hole portion 31211 is located on the side of the second jacket 312 facing the first jacket 311 and is adapted to the other end of the mandrel 1. That is, in this embodiment, the third hole portion 31211 is also a profiling hole, and the other end of the mandrel 1 can be inserted into the third hole portion 31211.

[0065] The fourth hole portion 31212 is located on the side of the third hole portion 31211 away from the first jacket 311. The second jacket 312 is sleeved on the outer periphery of the second shaft portion 3212 through the fourth hole portion 31212.

[0066] As described above, in this embodiment, before starting the winding operation, the staff can insert the two ends of the mandrel 1 into the first hole portion 31111 and the third hole portion 31211 respectively. Since both the first hole portion 31111 and the third hole portion 31211 are profiling holes and are respectively adapted to the two ends of the mandrel 1, when the first driving member 322 drives the first jacket 311 and the second jacket 312 to rotate around the axis of the rotating shaft subsequently, the rotating shaft can effectively drive the mandrel 1 to rotate.

[0067] After the winding operation is completed, the staff can take out the two ends of the mandrel 1 from the first hole portion 31111 and the third hole portion 31211 respectively, so as to remove the mandrel 1 from between the first jacket 311 and the second jacket 312, and then the carbon fiber tube can be removed from the mandrel 1 subsequently.

[0068] Based on the above, in this embodiment, the first jacket 311 and the second jacket 312 adapted to the specific shape of the mandrel 1 can be arranged correspondingly, so that the carbon fiber tube can be wound around the mandrel 1 correspondingly.

[0069] Exemplarily, if the mandrel 1 is a round rod, correspondingly, the first hole portion 31111 provided on the first jacket 311 sleeved on the first shaft portion 3211 is a round hole. Similarly, the third hole portion 31211 provided on the second jacket 312 sleeved on the second shaft portion 3212 is also a round hole. If the mandrel 1 is a special-shaped rod, correspondingly, the first hole portion 31111 provided on the first jacket 311 sleeved on the first shaft portion 3211 is a special-shaped profiling hole adapted to one end of the mandrel 1. Similarly, the third hole portion 31211 provided on the second jacket 312 sleeved on the second shaft portion 3212 is a special-shaped profiling hole adapted to the other end of the mandrel 1.

[0070] Further, in the present embodiment, a lock hole 3112 is formed in the outer wall of the first jacket 311. The lock hole 3112 extends radially along the second hole portion 31112 and communicates with the second hole portion 31112. A jack 32111 is provided along the radial direction of the first shaft portion 3211. A stop block 321111 is arranged inside the jack 32111. A lock rod 32112 is inserted into the jack 32111. First abutting blocks 321121 and second abutting blocks 321122 are respectively arranged at both ends of the lock rod 32112 along its axial direction. The lock rod 32112 passes through the stop block 321111, and the first abutting block 321121 and the second abutting block 321122 are respectively located on both sides of the stop block 321111 along the axial direction of the jack 32111. A first spring 321123 is sleeved on the outer periphery of the lock rod 32112. The first spring 321123 is a compression spring and is installed between the first abutting block 321121 and the stop block 321111. The lock rod 32112 has a first working position where the first abutting block 321121 extends out of the jack 32111 and extends into the lock hole 3112, and a second working position where it retracts into the jack 32111. The first spring 321123 is configured to drive the lock rod 32112 to reset from the second working position to the first working position. A second spring 32113 is sleeved on the outer periphery of the first shaft portion 3211. The second spring 32113 is installed on the side of the first jacket 311 away from the second jacket 312 and is compressed and deformed by the first jacket 311 when the lock rod 32112 is in the first working position.

[0071] On the side of the second jacket 312 away from the first jacket 311, a magnetic member 3122 is provided. The magnetic member 3122 is sleeved on the outer periphery of the second shaft portion 3212 and is fixedly connected to the second shaft portion 3212. The magnetic member 3122 can adsorb the second jacket 312.

[0072] Thus, in the present embodiment, when the lock rod 32112 is in the first working position, the first jacket 311 is locked on the first shaft portion 3211, and the magnetic member 3122 can lock the second jacket 312 on the second shaft portion 3212, so that the coiling operation can be performed.

[0073] In addition, after the roll manufacturing operation is completed and the mandrel 1 is removed between the first jacket 311 and the second jacket 312, the operator can press the first abutting block 321121 to switch the locking rod 32112 from the first working position to the second working position. At this time, the first jacket 311 can be pushed by the second spring 32113, so that the insertion hole 32111 is misaligned with the locking hole 3112, and then the operator can remove the first jacket 311 from the end of the first shaft portion 3211 close to the second shaft portion 3212. Correspondingly, the operator can pull the second jacket 312 to move toward the side away from the magnetic member 3122, so that the second jacket 312 can be removed from the end of the second shaft portion 3212 close to the first shaft portion 3211.

[0074] Correspondingly, the operator can press the first abutting block 321121 to switch the locking rod 32112 from the first working position to the second working position, so that the first jacket 311 can be sleeved on the first shaft portion 3211 from the end of the first shaft portion 3211 close to the second shaft portion 3212, and the insertion hole 32111 is aligned with the locking hole 3112. After that, the operator releases the pressing of the first abutting block 321121. Since the first spring 321123 will elastically deform when the locking rod 32112 is switched from the first working position to the second working position, after the operator releases the pressing of the first abutting block 321121, the first spring 321123 recovers its deformation, so that the locking rod 32112 can be reset from the second working position to the first working position. At this time, the first jacket 311 newly installed on the first shaft portion 3211 is locked on the first shaft portion 3211.

[0075] It should also be noted that in other alternative embodiments, the first spring 321123 can also be a tension spring and is installed between the second abutting block 321122 and the stop block 321111, so that it can recover its deformation after the operator releases the pressing of the first abutting block 321121, so that the locking rod 32112 can be reset from the second working position to the first working position. This embodiment does not make specific restrictions on this.

[0076] In addition, the operator can also sleeve the second jacket 312 on the second shaft portion 3212 from the end of the second shaft portion 3212 close to the first shaft portion 3211, and make the second jacket 312 contact the magnetic member 3122, so that the second jacket 312 newly installed on the second shaft portion 3212 is locked on the second shaft portion 3212.

[0077] As described above, in this embodiment, between two adjacent winding operations, the staff can replace the first jacket 311 and the second jacket 312 according to actual production requirements. Specifically, during actual production, when the mandrel 1 is changed in type due to actual production requirements, the staff can correspondingly replace the first jacket 311 and the second jacket 312, so as to be suitable for clamping the mandrel 1 after the type change. Based on the above, in this embodiment, a carbon fiber tube winding device can be compatible with winding carbon fiber tubes on mandrels 1 of different shapes, so as to produce carbon fiber tubes of different shapes. Moreover, this embodiment can realize the rapid disassembly and replacement of the first jacket 311 and the second jacket 312, thereby further improving the production efficiency of carbon fiber tubes.

[0078] Exemplarily, when the mandrel 1 is changed from a round rod to a special-shaped rod due to actual production requirements, the staff can first remove the first jacket 311 and the second jacket 312 adapted to the round rod from the rotating shaft, and then assemble the first jacket 311 and the second jacket 312 adapted to the special-shaped rod onto the rotating shaft.

[0079] It is worth noting that, in this embodiment, a protruding portion 32114 protrudes from the first shaft portion 3211. The second spring 32113 is installed on the side of the protruding portion 32114 facing the second shaft portion 3212, and is pressed and limited between the protruding portion 32114 and the first jacket 311 when the locking rod 32112 is in the first working position.

[0080] It is also worth noting that, in this embodiment, the rotating shaft is rotatably connected to the second mounting bracket 323. The second mounting bracket 323 includes a first frame body 3232 and a second frame body 3233. The first frame body 3232 and the second frame body 3233 are arranged at intervals along the first horizontal direction. The first shaft portion 3211 and the second shaft portion 3212 are respectively rotatably connected to the first frame body 3232 and the second frame body 3233.

[0081] As described above, it can be understood that, in other alternative embodiments, the second spring 32113 can also be directly pressed and limited between the first frame body 3232 and the first jacket 311 when the locking rod 32112 is in the first working position. This embodiment does not make specific restrictions on this.

[0082] In addition, based on the above, in this embodiment, the first driving member 322 is installed on the second frame body 3233 and is used to drive the second shaft portion 3212 to rotate around its axis. Since the mandrel 1 is clamped between the first jacket 311 and the second jacket 312, and the first jacket 311 is sleeved on the outer periphery of the first shaft portion 3211, the first shaft portion 3211 can rotate together with the second shaft portion 3212.

[0083] It can be understood that the first driving member 322 can be optionally a driving structure such as a servo motor or a stepping motor, and the present embodiment does not make specific limitations thereto.

[0084] It should also be noted that, in the present embodiment, the width of the locking hole 3112 along the axial direction of the first jacket 311 is greater than the width of the first abutting block 321121 along the axial direction of the first shaft portion 3211. Thus, after the first abutting block 321121 extends out of the insertion hole 32111 and extends into the locking hole 3112 to lock the first jacket 311 to the first shaft portion 3211, the first jacket 311 can still move toward the side away from the second shaft portion 3212, facilitating subsequent insertion of the mandrel 1 between the first jacket 311 and the second jacket 312 by the staff, but the first jacket 311 will not move toward the side close to the second shaft portion 3212.

[0085] Based on the foregoing, since the mandrel 1 clamped between the first jacket 311 and the second jacket 312 can be a round rod or a special-shaped rod. Among them, for the round rod, during the rotation of the mandrel 1, each part of the mandrel 1 along its circumferential direction will successively become the top of the mandrel 1, but the distance between the top of the mandrel 1 and the axis of the rotating shaft in the vertical direction always remains unchanged. That is, the roller 331 can keep pressing against the top of the mandrel 1 in the vertical direction. However, for the special-shaped rod, during the rotation of the mandrel 1, as each part of the mandrel 1 along its circumferential direction successively becomes the top of the mandrel 1, the distance between the top of the mandrel 1 and the axis of the rotating shaft in the vertical direction will change.

[0086] Therefore, to ensure that for the mandrel 1 which is a special-shaped rod, during the rotation of the mandrel 1, the roller 331 can always keep pressing against the top of the mandrel 1 in the vertical direction. In the present embodiment, the driving module 332 includes a mounting plate 3321, a second driving member 3322, a guide rod 3323 and a third spring 3324. The first mounting bracket 333 for mounting the roller 331 is slidably connected to the mounting plate 3321 in the vertical direction. Specifically, a first slide rail 3331 extending in the vertical direction is fixedly connected to the first mounting bracket 333, and a first slider 33211 is fixedly connected to the mounting plate 3321. The first slider 33211 is slidably connected to the first slide rail 3331. The second driving member 3322 can drive the mounting plate 3321 to move toward the clamping module, thereby driving the roller 331 to move toward the clamping module.

[0087] In addition, the guide rod 3323 extends in the vertical direction and is fixedly connected to the first mounting bracket 333. The mounting plate 3321 is sleeved on the outer periphery of the guide rod 3323, and the third spring 3324 is also sleeved on the outer periphery of the guide rod 3323 and is installed between the mounting plate 3321 and the first mounting bracket 333. After the carbon fiber composite fabric 2 is placed on the top of the mandrel 1, the second driving member 3322 can drive the mounting plate 3321 to move towards the clamping module, thereby driving the roller 331 to move towards the clamping module, so that the roller 331 presses the carbon fiber composite fabric 2 against the top of the mandrel 1. During the rotation of the mandrel 1, as each part of the mandrel 1 along its circumferential direction successively becomes the top of the mandrel 1, under the action of the third spring 3324, the roller 331 can adaptively adjust its height position according to the change in the distance between the top of the mandrel 1 and the axis of the rotating shaft in the vertical direction, so that the roller 331 can always keep pressing against the top of the mandrel 1.

[0088] It can be understood that when the second driving member 3322 can drive the mounting plate 3321 to move towards the clamping module, thereby driving the roller 331 to move towards the clamping module, the second driving member 3322 can adaptively adjust the compression amount of the third spring 3324 after the roller 331 presses against the mandrel 1 according to the contour of the special-shaped rod, so as to more effectively ensure that during the rotation of the mandrel 1, the roller 331 can always keep pressing against the top of the mandrel 1.

[0089] As such, the second driving member 3322 can be selected as a linear driving structure such as a cylinder or an electric cylinder, and this embodiment does not make specific limitations thereto.

[0090] In addition, it should be noted that in this embodiment, a third abutting block 33231 is provided at one end of the guide rod 3323 away from the first mounting bracket 333, and the third abutting block 33231 is located on the side of the mounting plate 3321 away from the first mounting bracket 333, so as to prevent the first mounting bracket 333 from falling off the mounting plate 3321.

[0091] Furthermore, the outer periphery of the roller 331 is coated with a foam 3311, so as to further ensure that the roller 331 can roll the carbon fiber composite fabric 2 evenly and flatly around the outer periphery of the mandrel 1.

[0092] Even further, the carbon fiber pipe rolling equipment further includes a tray 341. The tray 341 can be lifted and lowered in the vertical direction and has a third working position where it rises to be flush with the top of the mandrel 1 clamped between the first jacket 311 and the second jacket 312, and a fourth working position where it descends to be away from the clamping module. Moreover, the tray 341 is provided with an avoidance groove 3411, and when the tray 341 is in the third working position, the mandrel 1 is moved into the avoidance groove 3411.

[0093] As described above, after the carbon fiber composite fabric 2 is placed on top of the mandrel 1, the tray 341 moves from the fourth working position to the third working position, so that the tray 341 can support the part of the carbon fiber composite fabric 2 extending out of the mandrel 1 to prevent the carbon fiber composite fabric 2 from falling off the mandrel 1. After the roller 331 presses the carbon fiber composite fabric 2 against the top of the mandrel 1, the tray 341 moves from the third working position to the fourth working position, thus ensuring that the subsequent carbon fiber composite fabric 2 can be wound around the outer periphery of the mandrel 1.

[0094] Specifically, the carbon fiber pipe rolling device further includes a third driving member 342, and the third driving member 342 is configured to drive the tray 341 to move up and down in the vertical direction.

[0095] It can be understood that the third driving member 342 can be selected as a linear driving structure such as a cylinder or an electric cylinder, and the present embodiment does not make specific limitations thereto.

[0096] As described above, in this embodiment, the tray 341 includes a first supporting block 3412 and a second supporting block 3413 arranged along the first horizontal direction. The distance between the first supporting block 3412 and the second supporting block 3413 is adjustable. A first stop baffle 34131 is provided on the side of the second supporting block 3413 away from the first supporting block 3412 along the first horizontal direction. The first stop baffle 34131 extends along a second horizontal direction perpendicular to the first horizontal direction. The first stop baffle 34131 can provide positioning for the staff to place the carbon fiber composite fabric 2 in the first horizontal direction. Specifically, the staff can place the carbon fiber composite fabric 2 against the side of the first stop baffle 34131 facing the first supporting block 3412, so as to ensure that the subsequent carbon fiber composite fabric 2 can be accurately wound around the outer periphery of the mandrel 1.

[0097] Exemplarily, in this embodiment, the movable end of the third driving member 342 is connected to a second slide rail 3421. The second slide rail 3421 extends along the first horizontal direction. Both the first support block 3412 and the second support block 3413 are connected to the second slide rail 3421 through second sliders 34132. The position of one of the second sliders 34132 is locked so that the position of one of the first support block 3412 and the second support block 3413 relative to the second slide rail 3421 is fixed. The other second slider 34132 is screwed with a lead screw 34133. The lead screw 34133 extends along the second horizontal direction, and a handwheel 34134 is provided at one end of the lead screw 34133. The staff can manipulate the lead screw 34133 to move along the second horizontal direction through the handwheel 34134. When the lead screw 34133 drives the handwheel 34134 to press against one side of the second slide rail 3421 along the second horizontal direction, the relative positions of the first support block 3412 and the second support block 3413 are fixed. When the lead screw 34133 drives the handwheel 34134 away from the second slide rail 3421, the other second slider 34132 can slide along the second slide rail 3421, and the distance between the first support block 3412 and the second support block 3413 is adjustable.

[0098] In this embodiment, by adjusting the distance between the first support block 3412 and the second support block 3413, the position of the first stop baffle 34131 can be adjusted, so as to adapt to placing carbon fiber composite fabrics 2 of different sizes.

[0099] Furthermore, the tray 341 is further provided with a second stop baffle 3414. The second stop baffle 3414 extends along the first horizontal direction. The second stop baffle 3414 can further provide positioning for the staff to place the carbon fiber composite fabric 2. Specifically, based on the content described above, in this embodiment, the first driving member 322 first drives the clamping module to rotate clockwise along the axis of the rotating shaft, and then after the clamping module rotates counterclockwise along the axis of the rotating shaft and resets, the clamping module is further driven to rotate counterclockwise along the axis of the rotating shaft to wind the carbon fiber composite fabric 2. Thus, in this embodiment, the second stop baffle 3414 is located on one side of the avoidance groove 3411 along the second horizontal direction and extends along the first horizontal direction. The second stop baffle 3414 can provide positioning for the staff to place the carbon fiber composite fabric 2 in the second horizontal direction, so as to ensure the accurate placement position of the carbon fiber composite fabric 2, and further ensure that the first driving member 322 can first drive the clamping module to rotate clockwise along the axis of the rotating shaft by a first preset angle, and then after the clamping module rotates counterclockwise along the axis of the rotating shaft and resets, the clamping module is further driven to rotate counterclockwise along the axis of the rotating shaft by a second preset angle, so as to ensure that the subsequent carbon fiber composite fabric 2 can be wound more precisely around the outer circumference of the mandrel 1.

[0100] That is, in this embodiment, by controlling the placement position of the carbon fiber composite fabric 2, precise control of the rotation process of the clamping module can be achieved, thereby ensuring that the carbon fiber composite fabric 2 can be precisely wound around the outer periphery of the mandrel 1, further ensuring that the performance of the manufactured carbon fiber pipe meets the requirements.

[0101] It can be understood that in other alternative embodiments, it can also be: a scale line is provided on one side of the tray 341 along the first horizontal direction, and the scale line is marked along the second horizontal direction. The staff can place the carbon fiber composite fabric 2 according to the indication of the scale line, thereby ensuring the accurate placement position of the carbon fiber composite fabric 2.

[0102] Furthermore, in this embodiment, an installation sleeve is provided on the side of the second jacket 312 away from the first jacket 311. The installation sleeve is sleeved on the outer periphery of the rotating shaft. An indicating rod 31221 is fixedly connected to the installation sleeve. A photoelectric sensor 3231 is fixedly connected to the second mounting bracket 323. Specifically, the photoelectric sensor 3231 is fixedly connected to the second frame body 3233. The indicating rod 31221 can be aligned with the photoelectric sensor 3231 when the first driving member 322 drives the rotating shaft to return to the initial position. It can be understood that when the rotating shaft is at the initial position, the mandrel 1 is at the initial position. The indicating rod 31221 can cooperate with the photoelectric sensor 3231 for initial position positioning, thereby further achieving precise control of the rotation process of the clamping module, and further ensuring that the carbon fiber composite fabric 2 can be precisely wound around the outer periphery of the mandrel 1, further ensuring that the performance of the manufactured carbon fiber pipe meets the requirements.

[0103] It can be understood that in other alternative embodiments, it can also be: an installation sleeve is provided on the side of the first jacket 311 away from the second jacket 312. Correspondingly, the photoelectric sensor 3231 is fixedly connected to the first frame body 3232, or an installation sleeve is provided on the side of the first jacket 311 away from the second jacket 312 and on the side of the second jacket 312 away from the first jacket 311. Correspondingly, photoelectric sensors 3231 are fixedly connected to both the first frame body 3232 and the second frame body 3233. This embodiment does not make specific restrictions on this.

[0104] It is worth noting that in this embodiment, the installation sleeve has magnetism, that is, the installation sleeve forms the magnetic member 3122 mentioned above.

[0105] In addition, it should be noted that based on the content described above, in other alternative embodiments, the first driving member 322 may also drive the clamping module to rotate clockwise along the axis of the rotating shaft, so as to wind the carbon fiber composite material cloth 2 around the outer periphery of the mandrel 1. Or, the first driving member 322 may also drive the clamping module to rotate counterclockwise along the axis of the rotating shaft, so as to wind the carbon fiber composite material cloth 2 around the outer periphery of the mandrel 1. For the above two winding methods, the placement position of the carbon fiber composite material cloth 2 needs to satisfy that one side edge of the carbon fiber composite material cloth 2 along the second horizontal direction falls within the top area of the mandrel 1. At this time, it is not suitable to provide positioning for the staff to place the carbon fiber composite material cloth 2 in the second horizontal direction by setting the second stop plate 3414, so as to avoid interference with the mandrel 1 when the tray 341 is lifted and lowered.

[0106] Therefore, in other alternative embodiments, if the first driving member 322 drives the clamping module to rotate clockwise along the axis of the rotating shaft, so as to wind the carbon fiber composite material cloth 2 around the outer periphery of the mandrel 1, or, if the first driving member 322 drives the clamping module to rotate counterclockwise along the axis of the rotating shaft, so as to wind the carbon fiber composite material cloth 2 around the outer periphery of the mandrel 1, then in this embodiment, the scale line provided on one side of the tray 341 along the first horizontal direction is used to indicate the staff to place the carbon fiber composite material cloth 2, so as to ensure the accurate placement position of the carbon fiber composite material cloth 2.

[0107] Furthermore, in this embodiment, the clamping module further includes a first heater 313, and the first heater 313 is configured to heat the second jacket 312, so as to heat the mandrel 1 through the second jacket 312. Exemplarily, in this embodiment, the first heater 313 is a heating ring, and the first heater 313 is detachably hooped on the outer periphery of the second jacket 312.

[0108] Of course, in other alternative embodiments, the first heater 313 may also be configured to heat the first jacket 311, or the first heater 313 may also be configured to heat the first jacket 311 and the second jacket 312 simultaneously, so as to heat the mandrel 1. This embodiment does not make specific limitations on this.

[0109] In addition, the tray 341 is provided with a second heater 3415. Specifically, the second heater 3415 is provided on both the first support block 3412 and the second support block 3413. The second heater 3415 is used to heat the tray 341. The first heater 313 and the second heater 3415 cooperate to heat the mandrel 1 and the tray 341, so as to heat and soften the carbon fiber composite material cloth 2 placed on the mandrel 1 and the tray 341, and further facilitate the subsequent bonding of the carbon fiber composite material cloth 2 to the outer periphery of the mandrel 1 to form a carbon fiber pipe.

[0110] Furthermore, in this embodiment, the carbon fiber pipe rolling equipment further includes a support module 35. The support module 35 includes a third mounting frame 351 and two rollers 352 rotatably arranged on the third mounting frame 351. The axes of the two rollers 352 both extend along the first horizontal direction, and the two rollers 352 are arranged along the second horizontal direction. The first jacket 311 can be placed above the two rollers 352 and between the two rollers 352. The two rollers 352 can provide a supporting effect for the clamping module, so as to ensure that the first jacket 311 and the second jacket 312 can rotate more stably.

[0111] Obviously, the above embodiments of the present invention are merely examples for clearly explaining the present invention, rather than limiting the implementation manners of the present invention. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
