Technical Field

[0001] This utility model relates to the field of carbon fiber tube preparation technology, and in particular to a carbon fiber tube rolling device. Background Technology

[0002] Carbon fiber tubes are tubular components made of carbon fiber reinforced polymer (CFRP) fabric wound into shape. They have many advantages such as high temperature resistance, corrosion resistance, wear resistance, and high strength, and are therefore widely used in various industrial or daily life fields such as aviation and transportation.

Moreover, the quality stability of carbon fiber tubes obtained by manual winding is poor, and problems such as uneven tube forming and wrinkles in carbon fiber composite fabric are prone to occur, affecting the performance of the carbon fiber tubes produced.

It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0054] Please see Figures 1-16 This embodiment provides a carbon fiber tube winding device, which is used to replace manual winding on the mandrel 1 to form carbon fiber tubes, thereby improving the working efficiency of winding carbon fiber tubes and thus improving the production efficiency of carbon fiber tubes.

[0055] Specifically, the carbon fiber tube winding equipment includes a clamping module and a rotating mechanism 32. The clamping module includes a first clamp 311 and a second clamp 312 arranged at intervals along a first horizontal direction. The first clamp 311 and the second clamp 312 can respectively clamp the two ends of the mandrel 1, and the mandrel 1 is placed in a position 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 a 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. The first clamping sleeve 311 is sleeved on the outer periphery of the first shaft portion 3211, and the second clamping sleeve 312 is sleeved on the outer periphery of the second shaft portion 3212. 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, thereby driving the spindle 1 to rotate around the axis of the rotating shaft.

[0057] In addition to the clamping module and the rotating mechanism 32, the carbon fiber tube rolling equipment also includes a pressing module 33. The pressing module 33 includes a roller 331 and a drive 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 in the first horizontal direction. The drive module 332 is configured to drive the roller 331 to move toward the clamping module and to keep the roller 331 pressed against the top of the mandrel 1 in the vertical direction. It is also understood that the pressing module 33 includes a first mounting frame 333. The roller 331 is rotatably connected to the first mounting frame 333, thereby enabling the carbon fiber composite fabric 2 to be rolled.

[0058] Specifically, in this embodiment, the mandrel 1 is clamped between the first clamp 311 and the second clamp 312. The carbon fiber composite cloth 2 can be placed on top of the mandrel 1, and the roller 331 can press the carbon fiber composite cloth 2 against the top of the mandrel 1. Then, the first driving member 322 drives the first clamp 311 and the second clamp 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 cloth 2 is gradually wound around the outer circumference of the mandrel 1. Moreover, during the rotation of the mandrel 1, each part of the mandrel 1 along its circumference will successively become the top of the mandrel 1. Since the roller 331 always presses against the top of the mandrel 1, during the rotation of the mandrel 1, the roller 331 can continuously roll the carbon fiber composite cloth 2 to ensure that the carbon fiber composite cloth 2 is wound evenly and flatly around the outer circumference of the mandrel 1, thereby preventing the carbon fiber tube from having problems such as uneven tube forming and wrinkles in the carbon fiber composite cloth 2, and thus ensuring that the performance of the carbon fiber tube meets the requirements.

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

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

[0061] It is worth noting that in this embodiment, the first driving member 322 first drives the clamping module to rotate clockwise around the axis of the rotating shaft, and then drives the clamping module to rotate counterclockwise around the axis of the rotating shaft and reset it, and then drives the clamping module to continue to rotate counterclockwise around the axis of the rotating shaft, thereby winding the carbon fiber composite cloth 2 around the outer circumference of the mandrel 1. Of course, in other optional embodiments, the first driving member 322 may also drive the clamping module to rotate clockwise around the axis of the rotating shaft, thereby winding the carbon fiber composite cloth 2 around the outer circumference of the mandrel 1, or the first driving member 322 may also drive the clamping module to rotate counterclockwise around the axis of the rotating shaft, thereby winding the carbon fiber composite cloth 2 around the outer circumference of the mandrel 1. This embodiment does not impose specific limitations on this.

[0062] Based on the above description, in this embodiment, the first sleeve 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. The first hole portion 31111 is located on the side of the first sleeve 311 facing the second sleeve 312 and is adapted to one end of the mandrel 1. That is, in this embodiment, the first hole portion 31111 is a contour hole, and one end of the mandrel 1 can be inserted into the first hole portion 31111.

[0063] The second hole 31112 is located on the side of the first hole 31111 away from the second sleeve 312, and the first sleeve 311 is fitted onto the outer periphery of the first shaft 3211 through the second hole 31112.

[0064] Correspondingly, the second sleeve 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. For example, 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 sleeve 312 facing the first sleeve 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 contour hole, and the other end of the mandrel 1 can be inserted into the third hole portion 31211.

[0065] The fourth hole 31212 is located on the side of the third hole 31211 away from the first sleeve 311, and the second sleeve 312 is fitted onto the outer periphery of the second shaft 3212 through the fourth hole 31212.

[0066] Therefore, in this embodiment, before starting the rolling operation, the worker can insert the two ends of the mandrel 1 into the first hole 31111 and the third hole 31211 respectively. Since the first hole 31111 and the third hole 31211 are both contour holes and are adapted to the two ends of the mandrel 1 respectively, when the first driving member 322 drives the first clamp 311 and the second clamp 312 to rotate around the axis of the rotating shaft, the rotating shaft can effectively drive the mandrel 1 to rotate.

[0067] After the rolling operation is completed, the workers can take the two ends of the mandrel 1 out from the first hole 31111 and the third hole 31211 respectively, thereby removing the mandrel 1 from between the first clamp 311 and the second clamp 312, and then the carbon fiber tube can be removed from the mandrel 1.

[0068] Based on the above, in this embodiment, a first sleeve 311 and a second sleeve 312 that are adapted to the specific shape of the mandrel 1 can be arranged accordingly, so that carbon fiber tubing can be wound on the mandrel 1 accordingly.

[0069] For example, if the mandrel 1 is a round rod, then the first hole 31111 provided in the first sleeve 311 sleeved on the first shaft portion 3211 is a round hole. Similarly, the third hole 31211 provided in the second sleeve 312 sleeved on the second shaft portion 3212 is also a round hole. If the mandrel 1 is an irregularly shaped rod, then the first hole 31111 provided in the first sleeve 311 sleeved on the first shaft portion 3211 is an irregularly shaped hole that matches one end of the mandrel 1. Similarly, the third hole 31211 provided in the second sleeve 312 sleeved on the second shaft portion 3212 is an irregularly shaped hole that matches the other end of the mandrel 1.

[0070] Further, in this embodiment, the outer wall of the first sleeve 311 is provided with a locking hole 3112, which extends radially along the second hole portion 31112 and communicates with it. The first shaft portion 3211 is provided with an insertion hole 32111 along its radial direction. A stop block 32111 is provided inside the insertion hole 32111. A locking rod 32112 is inserted into the insertion hole 32111. A first abutment block 321121 and abutment block 321122 are respectively provided at both ends of the locking rod 32112 along its axial direction. The locking rod 32112 passes through the stop block 321111, and the first abutment block 321121 and the second abutment block 321122 are respectively located on both sides of the stop block 321111 along the axial direction of the insertion hole 32111. A first spring 321123 is sleeved on the outer periphery of the first abutment block 321121 and the stop block 321111. The locking rod 32112 has a first working position in which the first abutment block 321121 extends out of the insertion hole 32111 and into the locking hole 3112, and a second working position in which it retracts into the insertion hole 32111. The first spring 321123 is configured to drive the locking rod 32112 to return 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 clamping sleeve 311 away from the second clamping sleeve 312, and is compressed and deformed by the first clamping sleeve 311 when the locking rod 32112 is in the first working position.

[0071] A magnetic element 3122 is provided on the side of the second sleeve 312 away from the first sleeve 311. The magnetic element 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 element 3122 can attract the second sleeve 312.

[0072] Therefore, in this embodiment, when the locking rod 32112 is in the first working position, the first clamp 311 is locked on the first shaft portion 3211, and the magnetic component 3122 can lock the second clamp 312 on the second shaft portion 3212, thereby enabling the winding operation.

[0073] Furthermore, after the rolling operation is completed and the mandrel 1 is removed from between the first clamp 311 and the second clamp 312, the operator can press the first abutment block 321121 to switch the locking rod 32112 from the first working position to the second working position. At this time, the first clamp 311 can be pushed by the second spring 32113, thereby causing the insertion hole 32111 and the locking hole 3112 to be misaligned. This allows the operator to remove the first clamp 311 from the end of the first shaft portion 3211 near the second shaft portion 3212. Correspondingly, the operator can pull the second clamp 312 to move it away from the magnetic component 3122, thereby removing the second clamp 312 from the end of the second shaft portion 3212 near the first shaft portion 3211.

[0074] Accordingly, the operator can press the first abutment block 321121 to switch the locking rod 32112 from the first working position to the second working position, thereby enabling the first sleeve 311 to be fitted onto the first shaft 3211 from the end of the first shaft 3211 closest to the second shaft 3212, and aligning the insertion hole 32111 with the locking hole 3112. Afterwards, the operator releases the pressure on the first abutment block 321121. Since the first spring 321123 undergoes elastic deformation when the locking rod 32112 switches from the first working position to the second working position, the first spring 321123 returns to its original deformation after the operator releases the pressure on the first abutment block 321121, thereby enabling the locking rod 32112 to return from the second working position to the first working position. At this time, the first sleeve 311 newly installed on the first shaft 3211 is locked onto the first shaft 3211.

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

[0076] In addition, the staff can also fit the second clip 312 onto the second shaft 3212 from the end of the second shaft 3212 that is close to the first shaft 3211, and make the second clip 312 contact the magnetic component 3122, so that the second clip 312 newly installed on the second shaft 3212 is locked onto the second shaft 3212.

[0077] Therefore, in this embodiment, between two adjacent winding operations, the operator can replace the first clamp 311 and the second clamp 312 according to actual production needs. Specifically, in the actual production process, when the mandrel 1 is changed due to actual production needs, the operator can replace the first clamp 311 and the second clamp 312 accordingly, so as to be suitable for clamping the changed mandrel 1. Based on the above, in this embodiment, one carbon fiber tube winding equipment can be compatible with winding carbon fiber tubes of mandrel 1 of different shapes, thereby producing carbon fiber tubes of different shapes. Moreover, this embodiment can realize the quick replacement of the first clamp 311 and the second clamp 312, thereby further improving the production efficiency of carbon fiber tubes.

[0078] For example, when the mandrel 1 is changed from a round rod to a non-circular rod due to actual production needs, the worker can first remove the first sleeve 311 and the second sleeve 312 that are compatible with the round rod from the rotating shaft, and then assemble the first sleeve 311 and the second sleeve 312 that are compatible with the non-circular rod onto the rotating shaft.

[0079] It is worth noting that in this embodiment, the first shaft portion 3211 is provided with a protrusion 32114, and the second spring 32113 is installed on the side of the protrusion 32114 facing the second shaft portion 3212, and is pressed and limited between the protrusion 32114 and the first clip 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 bracket 3232 and a second bracket 3233. The first bracket 3232 and the second bracket 3233 are arranged at intervals along a first horizontal direction. The first shaft portion 3211 and the second shaft portion 3212 are rotatably connected to the first bracket 3232 and the second bracket 3233, respectively.

[0081] As can be understood from the above, in other alternative embodiments, the second spring 32113 may also be directly pressed and confined between the first frame 3232 and the first clamp 311 when the locking rod 32112 is in the first working position. This embodiment does not impose specific restrictions on this.

[0082] Furthermore, based on the above, in this embodiment, the first driving member 322 is mounted on the second frame 3233 and is used to drive the second shaft portion 3212 to rotate around its axis. Since the mandrel 1 is held between the first clamp 311 and the second clamp 312, and the first clamp 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 is understood that the first driving component 322 can be selected as a servo motor or a stepper motor, etc., and this embodiment does not impose specific restrictions on it.

[0084] It should also be noted that, in this embodiment, the width of the locking hole 3112 along the axial direction of the first sleeve 311 is greater than the width of the first abutting block 321121 along the axial direction of the first shaft portion 3211. This allows the first sleeve 311 to still move toward the side away from the second shaft portion 3212 after the first abutting block 321121 extends out of the insertion hole 32111 and into the locking hole 3112 to lock the first sleeve 311 onto the first shaft portion 3211. This facilitates the subsequent insertion of the mandrel 1 between the first sleeve 311 and the second sleeve 312, but the first sleeve 311 will not move toward the side closer to the second shaft portion 3212.

[0085] Based on the above description, the mandrel 1 clamped between the first clamp 311 and the second clamp 312 can be a round rod or an irregularly shaped rod. For a round rod, during the rotation of the mandrel 1, each part of the mandrel 1 along its circumference will successively become the top of the mandrel 1, but the distance between the top of the mandrel 1 and the axis of rotation in the vertical direction remains unchanged. That is, the roller 331 can keep pressing against the top of the mandrel 1 in the vertical direction. However, for an irregularly shaped rod, during the rotation of the mandrel 1, as each part of the mandrel 1 along its circumference successively becomes the top of the mandrel 1, the distance between the top of the mandrel 1 and the axis of rotation in the vertical direction will change.

[0086] Therefore, to ensure that the roller 331 can always keep pressing against the top of the mandrel 1 in the vertical direction during the rotation of the mandrel 1, in this embodiment, the drive module 332 includes a mounting plate 3321, a second drive 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 drive 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 vertically 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 sleeved on the outer periphery of the guide rod 3323 and installed between the mounting plate 3321 and the first mounting bracket 333. When the carbon fiber composite cloth 2 is placed on the top of the mandrel 1, 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, so that the roller 331 presses the carbon fiber composite cloth 2 against the top of the mandrel 1. During the rotation of the mandrel 1, as each part of the mandrel 1 along its circumference becomes the top of the mandrel 1 in sequence, under the action of the third spring 3324, the roller 331 can adaptively adjust its height position according to the change of the distance between the top of the mandrel 1 and the axis of rotation in the vertical direction, so that the roller 331 can always keep pressing against the top of the mandrel 1.

[0088] Understandably, when the second drive unit 3322 can drive the mounting plate 3321 to move toward the clamping module, thereby driving the roller 331 to move toward the clamping module, the second drive unit 3322 can adaptively adjust the compression of the third spring 3324 after the roller 331 presses against the mandrel 1 according to the contour of the irregular rod, so as to more effectively ensure that the roller 331 can always keep pressing against the top of the mandrel 1 during the subsequent rotation of the mandrel 1.

[0089] Therefore, the second driving component 3322 can be selected as a linear drive structure such as a cylinder or an electric cylinder, and this embodiment does not impose specific restrictions on it.

[0090] Additionally, it should be noted that in this embodiment, a third abutment block 33231 is provided at the end of the guide rod 3323 away from the first mounting bracket 333. The third abutment block 33231 is located on the side of the mounting plate 3321 away from the first mounting bracket 333, thereby preventing the first mounting bracket 333 from falling off the mounting plate 3321.

[0091] Furthermore, the outer periphery of the roller 331 is covered with foam 3311, thereby further ensuring that the roller 331 can roll the carbon fiber composite cloth 2 evenly and flatly around the outer periphery of the mandrel 1.

[0092] Furthermore, the carbon fiber tube winding equipment also includes a tray 341, which can be raised 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 held between the first clamp 311 and the second clamp 312, and a fourth working position where it falls away from the clamping module. The tray 341 is provided with a clearance groove 3411, and when the tray 341 is in the third working position, the mandrel 1 moves into the clearance groove 3411.

[0093] As described above, after the carbon fiber composite cloth 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 cloth 2 that extends out of the mandrel 1, so as to prevent the carbon fiber composite cloth 2 from falling off the mandrel 1. When the roller 331 presses the carbon fiber composite cloth 2 against the top of the mandrel 1, the tray 341 moves from the third working position to the fourth working position, so as to ensure that the carbon fiber composite cloth 2 can be wound around the outer periphery of the mandrel 1.

[0094] Specifically, the carbon fiber tube winding equipment also includes a third drive unit 342, which is configured to drive the tray 341 to move up and down in the vertical direction.

[0095] It is understood that the third drive component 342 can be selected as a linear drive structure such as a cylinder or an electric cylinder, and this embodiment does not impose specific restrictions on it.

[0096] Therefore, in this embodiment, the tray 341 includes a first support block 3412 and a second support block 3413 arranged along a first horizontal direction. The distance between the first support block 3412 and the second support block 3413 is adjustable. A first stop plate 34131 is provided on the side of the second support block 3413 away from the first support block 3412 along the first horizontal direction. The first stop plate 34131 extends along a second horizontal direction perpendicular to the first horizontal direction. The first stop plate 34131 can provide positioning for the worker to place the carbon fiber composite cloth 2 in the first horizontal direction. Specifically, the worker can place the carbon fiber composite cloth 2 against the side of the first stop plate 34131 facing the first support block 3412, thereby ensuring that the carbon fiber composite cloth 2 can be accurately wound around the outer periphery of the mandrel 1.

[0097] For example, in this embodiment, the movable end of the third drive member 342 is connected to a second slide rail 3421, which extends along a first horizontal direction. The first support block 3412 and the second support block 3413 are both connected to the second slide rail 3421 via second sliders 34132. One of the second sliders 34132 is locked in position to fix the position of one of the first support block 3412 and the second support block 3413 relative to the second slide rail 3421. The other second slider 34132 is screwed with a lead screw 34133, which extends along a second horizontal direction. One end of 133 is equipped with a handwheel 34134, which allows the operator to manipulate the lead screw 34133 to move along the second horizontal direction. 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 can be adjusted.

[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 plate 34131 can be adjusted, thereby accommodating the placement of carbon fiber composite fabrics 2 of different sizes.

[0099] Furthermore, the tray 341 is also provided with a second stop plate 3414, which extends along the first horizontal direction. The second stop plate 3414 can further provide positioning for the worker to place the carbon fiber composite fabric 2. Specifically, based on the above description, in this embodiment, the first driving member 322 first drives the clamping module to rotate clockwise around the axis of rotation. Then, after the clamping module rotates counterclockwise around the axis of rotation and resets, it is driven to continue rotating counterclockwise around the axis of rotation to wind the carbon fiber composite fabric 2. Thus, in this embodiment, the second stop plate 3414 is located in the clearance groove 3. 411 Extending along one side of the second horizontal direction and along the first horizontal direction, the second stop plate 3414 can provide positioning for the worker to place the carbon fiber composite cloth 2 in the second horizontal direction, thereby ensuring that the placement position of the carbon fiber composite cloth 2 is accurate. This ensures that the first drive member 322 can first drive the clamping module to rotate clockwise around the axis of the rotating shaft by a first preset angle. Then, after the clamping module rotates counterclockwise around the axis of the rotating shaft and resets, it can drive the clamping module to continue to rotate counterclockwise around the axis of the rotating shaft by a second preset angle. This ensures that the carbon fiber composite cloth 2 can be wound more accurately around the outer periphery of the mandrel 1.

[0100] That is, this embodiment can control the placement position of the carbon fiber composite cloth 2, thereby achieving precise control of the rotation process of the clamping module, and thus ensuring that the carbon fiber composite cloth 2 can be precisely wound around the outer circumference of the mandrel 1, so as to further ensure that the performance of the carbon fiber tube meets the requirements.

[0101] It is understood that other alternative embodiments may also include: 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, so that the staff can place the carbon fiber composite cloth 2 according to the indication of the scale line, thereby ensuring that the placement position of the carbon fiber composite cloth 2 is accurate.

[0102] Furthermore, in this embodiment, a mounting sleeve is provided on the side of the second clamping sleeve 312 away from the first clamping sleeve 311. The mounting sleeve is fitted around the outer periphery of the rotating shaft. An indicator rod 31221 is fixedly connected to the mounting sleeve, and a photoelectric sensor 3231 is fixedly connected to the second mounting frame 323. Specifically, the photoelectric sensor 3231 is fixedly connected to the second frame 3233. The indicator rod 31221 is directly opposite the photoelectric sensor 3231 when the first driving member 322 drives the rotating shaft to reset 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 indicator rod 31221 can cooperate with the photoelectric sensor 3231 to perform initial position positioning, thereby further realizing precise control of the rotation process of the clamping module, and further ensuring that the carbon fiber composite cloth 2 can be accurately wound around the outer periphery of the mandrel 1, so as to further ensure that the performance of the manufactured carbon fiber tube meets the requirements.

[0103] It is understood that in other optional embodiments, a mounting sleeve may be provided on the side of the first sleeve 311 away from the second sleeve 312, and the photoelectric sensor 3231 may be fixedly connected to the first frame 3232 accordingly. Alternatively, a mounting sleeve may be provided on the side of the first sleeve 311 away from the second sleeve 312 and the side of the second sleeve 312 away from the first sleeve 311, and the photoelectric sensor 3231 may be fixedly connected to both the first frame 3232 and the second frame 3233. This embodiment does not impose specific limitations on this.

[0104] It is worth noting that in this embodiment, the mounting sleeve is magnetic, that is, the mounting sleeve is formed as the magnetic element 3122 mentioned above.

[0105] Additionally, it should be noted that, based on the foregoing, in other optional embodiments, the first driving member 322 may also drive the clamping module to rotate clockwise around the axis of the rotating shaft, thereby winding the carbon fiber composite cloth 2 around the outer periphery of the mandrel 1. Alternatively, the first driving member 322 may also drive the clamping module to rotate counterclockwise around the axis of the rotating shaft, thereby winding the carbon fiber composite cloth 2 around the outer periphery of the mandrel 1. For the above two winding methods, the placement position of the carbon fiber composite cloth 2 needs to ensure that one edge of the carbon fiber composite cloth 2 along the second horizontal direction falls within the top area of ​​the mandrel 1. In this case, it is not suitable to provide positioning for the worker to place the carbon fiber composite 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 raised and lowered.

[0106] Therefore, in other optional embodiments, if the first driving member 322 drives the clamping module to rotate clockwise around the axis of the rotating shaft, thereby winding the carbon fiber composite cloth 2 around the outer periphery of the mandrel 1, or if the first driving member 322 drives the clamping module to rotate counterclockwise around the axis of the rotating shaft, thereby winding the carbon fiber composite 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 indicates to the worker to place the carbon fiber composite cloth 2, thereby ensuring that the placement position of the carbon fiber composite cloth 2 is accurate.

[0107] Furthermore, in this embodiment, the clamping module also includes a first heater 313, which is configured to heat the second jacket 312, thereby heating the mandrel 1 through the second jacket 312. For example, in this embodiment, the first heater 313 is a heating ring, and the first heater 313 is detachably clamped to 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 simultaneously heat the first jacket 311 and the second jacket 312, thereby heating the mandrel 1. This embodiment does not impose specific limitations on this.

[0109] In addition, the tray 341 is provided with a second heater 3415. Specifically, the first support block 3412 and the second support block 3413 are both provided with a second heater 3415. The second heater 3415 is used to heat the tray 341. The first heater 313 cooperates with the second heater 3415 to heat the mandrel 1 and the tray 341, thereby heating and softening the carbon fiber composite cloth 2 placed on the mandrel 1 and the tray 341, which makes it easier to subsequently attach the carbon fiber composite cloth 2 to the outer periphery of the mandrel 1 to form a carbon fiber tube.

[0110] Furthermore, in this embodiment, the carbon fiber tube winding equipment also includes a support module 35. The support module 35 includes a third mounting frame 351 and two rollers 352 rotatably mounted on the third mounting frame 351. The axes of the two rollers 352 extend along a first horizontal direction, and the two rollers 352 are arranged along a second horizontal direction. The first clamping sleeve 311 can be placed above the two rollers 352 and located between the two rollers 352. The two rollers 352 can provide support for the clamping module, thereby ensuring that the first clamping sleeve 311 and the second clamping sleeve 312 can rotate more stably.
