Description

Technical Field

[0001] This application relates to the technical field of carbon fiber production, and more specifically, to a carbon fiber winding protection device. Background Art

[0002] In the production of carbon fiber, winding is the last step of the finished product. The surface of the tow after process treatment is smooth and soft. However, during the production process, the performance fluctuations of the winding machine will affect the winding formation of the tow, and the sanitary environment during winding, human damage, and external force damage during transportation are important factors causing product performance loss. Summary of the Invention

[0003] The purpose of this application is to provide a carbon fiber winding protection device, which is used to be arranged outside the winding shaft to protect the tow on the winding shaft.

[0004] The embodiments of this application are implemented as follows:

[0005] In a first aspect, an embodiment of this application provides a carbon fiber winding protection device, including a first half shell and a second half shell that can enclose to form a cavity. The cavity is used to accommodate the winding shaft. One side of the first half shell is rotatably connected to one side of the second half shell, and the other side of the first half shell is detachably connected to the other side of the second half shell so that the cavity can be opened on this side; a wire inlet for the tow to pass through is provided on the circumferential surface of the cavity so that the tow is wound on the winding shaft; the wire inlet is arranged on the first half shell and / or the second half shell.

[0006] In the above technical solution, the cavity formed by the first half shell and the second half shell of the carbon fiber winding protection device can accommodate the winding shaft. Therefore, it can play a role in protecting the winding shaft with the tow wound thereon, reducing the damage to the tow on the winding shaft during transportation or other situations. Since one side of the first half shell and the second half shell is rotatable and the other side is detachably connected, the cavity can be opened on this side, so that the winding shaft can be loaded into the cavity or taken out of the cavity. Since a wire inlet for the tow to pass through is also provided on the circumferential surface of the cavity, the carbon fiber winding protection device provided by the above technical solution can also be used in the process of winding the tow on the winding shaft. By surrounding the winding shaft inside the carbon fiber winding protection device, the influence of the sanitary environment in the production workshop on the tow can be reduced.

[0007] In some alternative embodiments, the first half shell and the second half shell are detachably connected by a buckle.

[0008] In some alternative embodiments, both the first half shell and the second half shell include a plurality of adjacent arc-shaped units; between two adjacent arc-shaped units in the first half shell, and between two adjacent arc-shaped units in the second half shell, a tightening assembly and a reset assembly are connected; the tightening assembly is configured to bring two adjacent arc-shaped units closer to each other to reduce the radial dimension of the cavity; the reset assembly is configured to move two adjacent arc-shaped units away from each other to increase the radial dimension of the cavity. The arc-shaped unit is also connected with a distance sensor for detecting the position of the outer periphery of the wire bundle on the surface of the winding shaft, and the distance sensor is in signal connection with the tightening assembly and / or the reset assembly to change the radial dimension of the cavity.

[0009] In the above technical solution, both the first half shell and the second half shell include arc-shaped units, and a tightening assembly and a reset assembly are connected between two adjacent arc-shaped units. The tightening assembly can bring two adjacent arc-shaped units closer to each other to reduce the radial dimension of the cavity, and the reset unit can move two adjacent arc-shaped units away from each other to increase the radial dimension of the cavity. Since a distance sensor is used to detect the position of the outer periphery of the wire bundle, and the distance sensor is in signal connection with the tightening assembly and / or the reset assembly, therefore, during the process of winding the wire bundle, the radial dimension of the cavity can be adaptively adjusted according to the position of the outer periphery of the wire bundle on the winding shaft. In other cases, the dimension of the cavity can also be adjusted according to the radial dimension of the winding shaft to adapt to winding shafts of different dimensions.

[0010] In some alternative embodiments, the tightening assembly includes a tightening device, a connecting rope, and a fixed end. The fixed end is disposed on one of the arc-shaped units, the tightening device is disposed on another adjacent arc-shaped unit, and the tightening device has a rotatable tightening shaft; one end of the connecting rope is connected to the fixed end and the other end is connected to the tightening shaft.

[0011] The tightening assembly is configured as follows: the tightening shaft of the tightening device rotates in a first direction to bring the arc-shaped units connected to both ends of the connecting rope closer to each other; the tightening shaft of the tightening device rotates in a second direction, and the arc-shaped units connected to both ends of the connecting rope move away from each other under the action of the reset assembly; the first direction is opposite to the second direction.

[0012] In the above technical solution, two adjacent arc units are connected by a connecting rope, which has a simple structure and is easy to implement. By connecting one end of the connecting rope to the tightening shaft of the tightening device, the one end of the connecting rope can be wound around the tightening shaft by the rotation of the tightening shaft in the first direction, so that the two adjacent arc units connected by the connecting rope approach each other, achieving the effect of reducing the radial dimension of the cavity. When the tightening shaft rotates in the second direction, the connecting rope is released from the tightening shaft, and the reset assembly separates the two adjacent arc units from each other until they are separated to the position where the connecting rope is taut. Therefore, in the above technical solution, the effect of adjusting the radial dimension of the cavity can be achieved by the rotation of the tightening shaft.

[0013] In some alternative embodiments, the arc unit includes an arc shell, and the arc shell within the first half shell and the second half shell encloses the cavity; a jack is provided on the first side of the arc shell; the reset assembly includes a plug rod and a spring; the spring is disposed at the bottom of the jack of one of the arc shells and abuts against it, and the plug rod is fixedly connected to the second side of the adjacent other arc shell and extends into the jack and abuts against and compresses the spring; the first side and the second side of the arc shell are opposite sides.

[0014] In the above technical solution, the arc unit includes an arc shell, and the plug rod connected to one arc shell is inserted into the jack of the adjacent arc shell, which can make the integrity of the first half shell and the second half shell formed by the arc units better. By arranging the spring in the jack, the expansion and contraction of the spring can be restricted by the jack, and the two adjacent arc shells can be better separated from each other under the action of the spring.

[0015] In some alternative embodiments, it further includes an installation cylinder, and the axial two ends of the arc unit are slidably connected to the installation cylinder, and the sliding direction of the arc unit is the radial direction; the carbon fiber winding protection device is configured such that when the radial dimension of the cavity changes, the arc unit slides along the radial direction.

[0016] During the process of the two arc units moving away from each other, the radial dimension of the cavity increases. Correspondingly, the arc unit also moves in the radial direction of the cavity. By slidably connecting the axial two ends of the arc top unit to the installation cylinder and the sliding direction being the radial direction of the cavity, the arc unit can move smoothly during the change of the radial dimension of the cavity.

[0017] In some alternative embodiments, the installation cylinder is an annular member, and the annular hole of the annular member communicates with the cavity for the wire winding shaft to pass through; a strip hole is radially provided on the arc shell, and one end of the strip hole penetrates the inner wall of the arc shell, and the installation cylinder is connected with a limiting member, and the limiting member penetrates through the strip hole and can slide along the extending direction of the strip hole.

[0018] In the above technical solution, the relative sliding between the arc-shaped shell and the annular member is achieved by the relative sliding of the limiting member in the strip-shaped hole, and by adopting the relative sliding of the limiting member in the strip-shaped hole, it can play a guiding role in the relative sliding between the arc-shaped unit and the mounting cylinder.

[0019] In some alternative embodiments, a plurality of rollers are provided on the inner wall of the mounting cylinder, and the plurality of rollers are circumferentially distributed along the mounting cylinder, and the axial direction of the rollers is parallel to the axial direction of the annular hole; the rollers are used to contact the circumferential surface of the wire winding shaft.

[0020] In the above technical solution, the plurality of rollers provided on the inner wall of the mounting cylinder contact the circumferential surface of the wire winding shaft, which can play a role in supporting the mounting cylinder outside the wire winding shaft, and can play a role in maintaining the coaxiality between the mounting cylinder and the wire winding shaft to a certain extent. During the rotation of the wire winding shaft, the rollers can relatively roll on the circumferential surface of the wire winding shaft, reducing the friction with the wire winding shaft.

[0021] In some alternative embodiments, an arc-shaped track is connected to one of the arc-shaped units in the first half shell, and a counterweight is variably arranged at the position of the arc-shaped track; the counterweight is configured to: when the position changes, the carbon fiber winding protection device rotates to change the position of the wire inlet.

[0022] Since the carbon fiber winding protection device is supported outside the wire winding shaft by the rollers provided in the mounting cylinder, relative rotation can occur between the two. By arranging a counterweight on the arc-shaped track connected to the arc-shaped unit, it is possible to adjust the position of the counterweight to make the carbon fiber winding protection device rotate, thereby changing the position of the wire inlet.

[0023] In some alternative embodiments, two opposite first roller shafts are rotatably arranged at the edge of the wire inlet, the first roller shafts extend along the axial direction of the cavity, and the space between the two first roller shafts is for the wire bundle to pass through.

[0024] In the above technical solution, by rotatably arranging the first roller shafts at the edge of the wire inlet and the first roller shafts extend along the axial direction of the cavity, during the process of winding the wire bundle, the rotatable first roller shafts can contact the wire bundle, reducing the wear on the wire bundle.

[0025] In some alternative embodiments, two opposite second roller shafts are rotatably arranged at the edge of the wire inlet, the second roller shafts extend along a direction perpendicular to the axial direction of the cavity; the space between the two second roller shafts is for the wire bundle to pass through; the two second roller shafts are also configured to be slidable along the axial direction of the cavity to guide the wire bundle to move along the axial direction of the wire winding shaft.

[0026] In the above technical solution, the two second roller shafts that can slide along the axial direction of the cavity guide the fiber bundle to move along the axial direction of the reel, so that the fiber bundle can be evenly wound on the winding shaft, reducing the occurrence of wire skipping and other situations caused by performance fluctuations of the winding machine and other reasons.

[0027] In some alternative embodiments, flexible materials are connected between two adjacent arc units in the first half shell and between two adjacent arc units in the second half shell. The flexible materials are used to cover the gaps generated during the process of increasing the radial dimensions of the first half shell and the second half shell.

Detailed implementation manners

[0040] To make the objectives, technical solutions and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are some but not all of the embodiments of this application. Usually, the components of the embodiments of this application described and illustrated in the accompanying drawings here can be arranged and designed in various different configurations.

[0041] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of this application that is claimed, but merely represents the selected embodiments of this application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in this application without creative efforts fall within the scope of protection of this application.

[0042] It should be noted that: Similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0043] In the description of this application, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the product of this application is usually placed when in use. It is only for the convenience of describing this application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be construed as a limitation of this application. In addition, the terms "first", "second", "third", etc. are only used for distinguishing descriptions and cannot be construed as indicating or implying relative importance.

[0044] In addition, terms such as "horizontal", "vertical", "hanging", etc. do not require the components to be absolutely horizontal or hanging, but can be slightly inclined. For example, "horizontal" only means that its direction is more horizontal relative to "vertical", and does not mean that the structure must be completely horizontal, but can be slightly inclined.

[0045] In the description of the present application, it should also be noted that unless otherwise clearly specified and limited, the terms "set", "installed", "connected", "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium, and can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.

[0046] The present application provides a carbon fiber production system, which has a bracket and a wire winding shaft. The wire winding shaft is arranged on the bracket and can rotate to wind the produced fiber bundle around its outer periphery. A carbon fiber winding protection device is also sleeved outside the wire winding shaft to separate dust and other impurities in the air from the wire winding shaft, and reduce the situation of reducing the quality of the fiber bundle due to impurities.

[0047] Such as Figure 1 And Figure 3 As shown, the carbon fiber winding protection device includes two half shells that can enclose to form a cavity. The two half shells are respectively denoted as the first half shell 110 and the second half shell 120. The cavity formed by the first half shell 110 and the second half shell 120 is used to accommodate the wire winding shaft 200. One side of the first half shell 110 is rotatably connected to one side of the second half shell 120, and the other side of the first half shell 110 is detachably connected to the other side of the second half shell 120, so that the cavity can be opened on this side. When the connection relationship is released on the side where the first half shell 110 and the second half shell 120 are detachably connected to open the cavity, it is convenient to load the wire winding shaft 200 into the cavity or take out the wire winding shaft 200 from the cavity. When the carbon fiber winding protection device is arranged outside the wire winding shaft, the axis of the cavity is nearly parallel to the axis of the wire winding shaft. By arranging the carbon fiber winding protection device provided by the present application outside the wire winding shaft 200 wound with the fiber bundle, it can play a protective role for the fiber bundle and reduce the situation of damaging the fiber bundle on the winding shaft during transportation or other situations. Among them, the fiber bundle refers to the produced filamentous carbon fiber.

[0048] Such as Figure 2As shown, the peripheral surface of the cavity has a wire inlet 311 for the wire bundle to pass through. During the winding process, that is, when winding the wire bundle around the winding shaft 200, the wire bundle outside the cavity can pass through the wire inlet 311 and be wound onto the winding shaft 200 inside the cavity. The wire inlet 311 can be arranged on the first half shell 110 or on the second half shell 120. The carbon fiber winding protection device provided in this application can be applied to the winding process of the wire bundle, thereby reducing the impact of the sanitary environment in the production workshop on the wire bundle. For example, by arranging the winding shaft 200 inside the cavity for the winding process, the situation where impurities in the air adhere to the wire bundle on the winding shaft 200 can be reduced, thereby reducing the impact on the wire bundle.

[0049] In some embodiments, one side of the first half shell 110 and the second half shell 120 can be rotatably connected by means such as hinge connection or rotating shaft connection; the other side can be detachably connected by means of a buckle. In other embodiments, other methods can also be used to achieve the rotatable connection of one side and the detachable connection of the other side of the first half shell 110 and the second half shell 120. Further, the first half shell 110 and the second half shell 120 can be transparent structural members for easy observation into the cavity.

[0050] In some embodiments, both the first half shell 110 and the second half shell 120 include a plurality of adjacent arc-shaped units 300, and the wire inlet 311 is arranged on the arc-shaped unit 300. A tightening component 400 and a reset component are connected between two adjacent arc-shaped units 300 of the first half shell 110 and between two adjacent arc-shaped units 300 of the second half shell 120. The tightening component 400 can make two adjacent arc-shaped units 300 approach each other to reduce the radial dimension of the cavity (that is, the carbon fiber winding protection device changes from the state shown in Figure 3 to the state shown in Figure 1 ); the reset component can make two adjacent arc-shaped units 300 move away from each other to increase the radial dimension of the cavity (that is, the carbon fiber winding protection device changes from the state shown in Figure 1 to the state shown in Figure 3 ). Further, the two arc-shaped units 300 connected by the tightening component 400 can both belong to the first half shell 110, or both belong to the second half shell 120, or one belongs to the first half shell 110 and the other belongs to the second half shell 120. In this embodiment, the radial dimension of the cavity can be adjusted by the tightening component 400 and the reset component to adapt to winding shafts 200 of different sizes. Among them, the radial dimension of the cavity is in the direction perpendicular to the axial direction. When the carbon fiber winding protection device provided in this application is installed outside the winding shaft 200, the axial direction of the cavity is almost parallel to the axial direction of the winding shaft 200. Further, the arc-shaped unit 300 can be a transparent structural member for easy observation into the cavity.

[0051] Further, in some embodiments, such as Figure 2 As shown, the arc unit 300 is further connected with a distance sensor 600 for detecting the position of the outer periphery of the wire bundle on the surface of the wire spool 200. The distance sensor 600 is signal-connected to the tightening assembly 400 and / or the reset assembly to change the radial dimension of the cavity. By detecting the position of the outer periphery of the wire bundle, the distance between the outer periphery of the wire bundle and the distance sensor 600 can be reflected. When this distance decreases to a preset value (such as 10 mm), the tightening assembly 400 and / or the reset assembly can be made to work, thereby increasing the radial dimension of the cavity. For example, in some embodiments, the distance sensor 600 is signal-connected to the tightening assembly 400. When the distance detected by the distance sensor 600 decreases to the preset value, the distance sensor 600 sends a signal to the tightening assembly 400 to make the tightening assembly 400 reduce the acting force that makes two adjacent arc units 300 approach each other. Then, the two adjacent arc units 300 move away from each other under the action of the reset assembly, so as to increase the radial dimension of the cavity.

[0052] Further, the distance sensor 600 can be provided only on the arc unit 300 of the first half shell 110, or only on the arc unit 300 of the second half shell 120, or the distance sensor 600 can be provided on the arc units 300 of both the first half shell 110 and the second half shell 120.

[0053] In some embodiments, the tightening assembly 400 includes a tightening device 410, a connecting rope 420 and a fixed end 430. The fixed end 430 is arranged on one arc unit 300, the tightening device 410 is arranged on another adjacent arc unit 300, one end of the connecting rope 420 is connected to the fixed end 430, and the other end is connected to the tightening device 410, so as to connect two adjacent arc units 300 through the tightening assembly 400, so that the two arc units 300 can approach each other, thereby reducing the radial dimension of the cavity. Further, the fixed end 430 and the tightening device 410 in the same tightening assembly 400 are arranged on the arc units 300 of the same half shell.

[0054] In some embodiments, the tightening device 410 has a rotatable tightening shaft. One end of the connecting rope 420 is connected to the fixed end 430, and the other end is connected to the tightening shaft. By rotating the tightening shaft in the first direction, one end of the connecting rope 420 can be wound on the tightening shaft, so as to pull the fixed end 430 connected to the safety rope and the tightening shaft closer to each other, thereby making the arc unit 300 provided with the fixed end 430 and the arc unit 300 provided with the tightening shaft approach each other, and realizing that two adjacent arc units 300 approach each other through the tightening assembly 400. When the arc units 300 in both the first half shell 110 and the second half shell 120 approach each other, the radial dimension of the cavity can be reduced.

[0055] Further, the tightening shaft can also rotate in a second direction opposite to the first direction, so that the connecting rope 420 is released from the tightening shaft, enabling the two arc-shaped units 300 connected by the tightening assembly 400 to move away from each other. The two arc-shaped units 300 move away from each other under the action of the reset unit until the position where the connecting rope 420 in the tightening assembly 400 connecting the two arc-shaped units 300 is tightened. When the arc-shaped units 300 in the first half shell 110 and the second half shell 120 both move away from each other, the radial dimension of the cavity can be increased.

[0056] In some embodiments, the connecting rope 420 can be a steel wire rope or a rope made of other metal materials; it can also be a rope made of non-metal materials such as a nylon rope.

[0057] In some embodiments, the tightening shaft is driven to rotate by electricity. For example, the tightening device 410 further includes a motor, and the tightening shaft is connected to the output shaft of the motor. Further, the tightening device 410 further includes a power source and a charger. The power source is used to supply power to the motor so that the motor drives the tightening shaft to rotate in the first direction or the second direction. The charger is used to charge the power source. Further, the charger can charge the power source in a wireless charging manner.

[0058] In some embodiments, such as Figure 1 、 Figure 3 and Figure 4 As shown, the arc-shaped unit 300 includes an arc-shaped shell 310. A jack 312 is provided on the first side of the arc-shaped shell 310. The arc-shaped shells 310 in the first half shell 110 and the second half shell 120 together enclose a cavity. The reset assembly includes a plug rod 510 and a spring 520. The spring 520 is arranged at the bottom of the jack 312 of an arc-shaped shell 310 and abuts against the bottom of the jack 312. The plug rod 510 in the reset assembly is fixedly connected to the second side of an adjacent arc-shaped shell 310 and extends into the jack 312 and abuts against and compresses the spring 520 in the jack 312. Further, both the jack 312 and the plug rod 510 are arc-shaped structures. Among them, the first side and the second side of the arc-shaped shell 310 are opposite sides of the arc-shaped shell 310. Further, the first side and the second side of the arc-shaped shell 310 are circumferentially opposite sides. In this embodiment, during the process of the adjacent two arc-shaped units 300 in the first half shell 110 and the second half shell 120 approaching or moving away from each other, the adjacent arc-shaped shells 310 also approach or move away from each other. Further, the arc-shaped shell 310 can be a transparent structural member to facilitate observing into the cavity.

[0059] Further, the tightening assembly 400 is also disposed on the arc-shaped housing 310, that is, the fixed end 430 of the tightening assembly 400 is disposed on the outer peripheral surface of one arc-shaped housing 310, and the tightening device 410 is disposed on the outer peripheral surface of another adjacent arc-shaped housing 310. Since the arc-shaped housings 310 are connected not only through the tightening assembly 400 but also by inserting the insertion rod 510 into the insertion hole 312, the integrity between the arc-shaped housings 310 in the first half shell 110 and between the arc-shaped housings 310 in the second half shell 120 can be better.

[0060] In some embodiments, as Figure 1 shown in Figure 3 , the carbon fiber winding protection device further includes an installation cylinder 700. The axial ends of the arc-shaped unit 300 are slidably connected to the installation cylinder 700, and the sliding directions of the arc-shaped unit 300 are all in the radial direction, that is, the axial ends of the arc-shaped housing 310 are slidably connected to the installation cylinder 700. Among them, the radial direction is the radial direction of the cavity, and the axial directions of the arc-shaped unit 300 and the arc-shaped housing 310 are also the axial direction of the cavity; the arc-shaped unit 300 can move in the radial direction when the radial dimension of the cavity changes.

[0061] Further, in some embodiments, as Figure 3 shown in

[0062] When the adjacent two arc-shaped units 300 move away from each other, the radial dimension of the cavity becomes larger, and a gap will appear between the adjacent two arc-shaped units 300. Therefore, flexible materials can also be connected between the adjacent two arc-shaped units 300 in the first half shell 110 and the second half shell 120 to cover the gap that appears between the adjacent two arc-shaped units 300 and reduce the entry of external impurities into the cavity. Further, the flexible material can be a transparent plastic film. Figure 3

[0063] Figure 9 In some embodiments, as Figure 10 shown in Figures 5 to 8 , an arc-shaped unit 300 in the first half shell 110 and another adjacent arc-shaped unit 300 in the second half shell 120 can be relatively fixedly connected, that is, during the process of increasing the cavity size, the relative positions between the two arc-shaped units 300 change. Figures 5 to 8As shown, a strip-shaped hole 315 is radially provided in the arc-shaped shell 310, and one end of the strip-shaped hole 315 penetrates through the inner wall of the arc-shaped shell 310. Further, the arc-shaped shell 310 includes a cylindrical plate 313 and sector plates 314 connected to both ends of the cylindrical plate 313 in the axial direction of the cavity. The outer peripheral surface of the cylindrical plate 313 is a cylindrical surface. The strip-shaped hole 315 is provided in the sector plate 314, the tightening assembly 400 is provided on the outer peripheral surface of the cylindrical plate 313, and the wire inlet 311 is provided on one cylindrical plate 313. The mounting cylinder 700 is connected with a limiting member 710, and the limiting member 710 penetrates through the strip-shaped hole 315 and can slide along the extending direction of the strip-shaped hole 315; wherein, the extending direction of the strip-shaped hole 315 is the radial direction of the arc-shaped shell 310, which is also the radial direction of the cavity and the radial direction of the sector plate 314. When the arc-shaped units 300 move away from each other to increase the radial dimension of the cavity, the arc-shaped shell 310 can move from Figure 1 the position shown to Figure 3 the position shown. During this process, the limiting member 710 slides in the strip-shaped hole 315 relative to the strip-shaped hole 315. The cooperation between the strip-shaped hole 315 and the limiting member 710 can guide the movement of the arc-shaped shell 310, making the movement of the arc-shaped shell 310 smoother.

[0064] In some embodiments, as Figure 3 , Figure 9 and Figure 10 shown, the mounting cylinder 700 includes a sheet body 731 and a cylindrical body 732, and the sheet body 731 and the cylindrical body 732 are connected into an annular member; the limiting member 710 is provided on the sheet body 731. The sheet body 731 is provided inside the arc-shaped shell 310 (that is, located inside the cavity), one end of the cylindrical body 732 is connected to the sheet body 731, and the other end is located outside the arc-shaped shell 310. In other embodiments, it may also be that the sheet body 731 is connected to the outside of the arc-shaped shell 310, one end of the cylindrical body 732 is connected to the sheet body 731, and the other end is also located outside the arc-shaped shell 310. The limiting member 710 may be a bolt threadedly connected to the sheet body 731. The head of the bolt and one of the sheet body 731 are located inside the arc-shaped shell 310, and the other is located outside the arc-shaped shell 310. That is, the sector plate 314 in the arc-shaped shell 310 is restricted between the head of the bolt and the sheet body 731 to restrict the movement of the arc-shaped shell 310 in the axial direction of the cavity.

[0065] Further, in some embodiments, the mounting cylinder 700 may include a first half cylinder 721 and a second half cylinder 722. Both the first half cylinder 721 and the second half cylinder 722 include a half sheet body 731 and a half cylinder body 732. The first half cylinder 721 and the second half cylinder 722 may have the same shape structure. The mounting cylinder 700 is formed by combining the first half cylinder 721 and the second half cylinder 722. Both the first half cylinder 721 and the second half cylinder 722 are connected to the arc unit 300. Further, the first half shell 110 includes the first half cylinder 721 and the arc unit 300 connected to the first half cylinder 721; the second half shell 120 includes the second half cylinder 722 and the arc unit 300 connected to the second half cylinder 722. One side of the first half cylinder 721 is rotatably connected to one side of the second half cylinder 722 to realize the rotational connection between one side of the first half shell 110 and one side of the second half shell 120; the other side of the first half cylinder 721 is detachably connected to the other side of the second half cylinder 722 to enable the cavity to open on this side; wherein, the first half cylinder 721 and the second half cylinder 722 can be detachably connected through a buckle 1100. In this embodiment, during the movement of the arc unit 300 to change the radial dimension of the cavity, the first half cylinder 721 and the second half cylinder 722 in the mounting cylinder 700 can be relatively stationary.

[0066] In some embodiments, as Figure 3 shown, a plurality of rollers 800 are further provided on the inner wall of the mounting cylinder 700. The rollers 800 are circumferentially distributed along the mounting cylinder 700. The axial direction of the rollers 800 is parallel to the axial direction of the annular hole, that is, parallel to the axial direction of the cavity. After installing the carbon fiber winding protection device provided in this embodiment outside the winding shaft 200, the rollers 800 contact the circumferential surface of the winding shaft 200, and during the rotation of the winding shaft 200, the rollers 800 roll relatively on the circumferential surface of the winding shaft 200. The plurality of rollers 800 provided on the inner wall of the mounting cylinder 700 contacting the circumferential surface of the winding shaft 200 can play a role in supporting the mounting cylinder 700 outside the winding shaft 200, and can also play a role in maintaining the coaxiality between the mounting cylinder 700 and the winding shaft 200 to a certain extent. During the rotation of the winding shaft 200, the rollers 800 roll relatively on the circumferential surface of the winding shaft 200, reducing the friction with the winding shaft 200.

[0067] In some embodiments, as Figure 1 and Figure 2As shown, an arc-shaped unit 300 within the first half shell 110 or the second half shell 120 is further connected to an arc-shaped track 910, and a counterweight 920 is variably disposed on the arc-shaped track 910. That is, an operator can change the position of the counterweight 920 on the arc-shaped track 910, thereby changing the center of gravity of the carbon fiber winding protection device. Since the carbon fiber winding protection device is supported on the winding shaft 200 by rollers 800, after the change in the carbon fiber winding protection device occurs, the carbon fiber winding protection device disposed outside the winding shaft 200 will spontaneously rotate, thereby changing the position of the wire inlet 311 to achieve the purpose of adjusting the position of the wire inlet 311. In some embodiments, the counterweight 920 can be a metal structural member such as an iron block, or a structural member of other materials. The center position of the arc-shaped track 910 can be located on the axis direction of the cavity, or can be not located on the axis direction of the cavity. In this embodiment, the carbon fiber winding protection device can be supported on the winding shaft 200 only by the rollers 800 without being connected to other structures, making disassembly and assembly more convenient.

[0068] In some embodiments, both the arc-shaped track 910 and the wire inlet 311 can be disposed in the first half shell 110 or the second half shell 120, or one of them can be disposed in the first half shell 110 and the other can be disposed in the second half shell 120.

[0069] Furthermore, the number of the arc-shaped tracks 910 is two, and the two arc-shaped tracks 910 are symmetrically disposed at both ends of the arc-shaped unit 300, so that the acting forces of the two arc-shaped tracks 910 on the arc-shaped unit 300 are difficult to cause the carbon fiber winding protection device to have a tendency to deflect in the direction perpendicular to the cavity axis. In some embodiments, the arc-shaped track 910 is disposed on the side of the sector plate 314 of the arc-shaped shell 310 away from the cavity. Further, one end of the counterweight 920 is connected to one arc-shaped track 910 and the other end is connected to the other arc-shaped track 910.

[0070] Furthermore, as Figure 1 With Figure 2As shown, two opposite first roller shafts 1010 are rotatably arranged at the edge of the wire inlet 311, and the first roller shafts 1010 extend along the axial direction of the cavity. During the process of winding the wire bundle, the wire bundle can pass through between the two first roller shafts 1010. Even if the rotation angle of the carbon fiber winding protection device is too large, causing the first roller shafts 1010 in the carbon fiber winding protection device to contact the wire bundle, since the first roller shafts 1010 can rotate, the first roller shafts 1010 will rotate under the action of the wire bundle, reducing the friction with the wire bundle, and thus reducing the damage to the wire bundle. Therefore, in this embodiment, the risk of the wire bundle being worn due to contact between the wire bundle and the carbon fiber winding protection device caused by excessive adjustment of the position of the counterweight 920 can be effectively reduced; the carbon fiber winding protection device can also be rotated by changing the position of the counterweight 920 on the arc track 910, thereby changing the wrap angle of the wire bundle on the first roller shafts 1010.

[0071] Further, in some embodiments, such as Figure 1 With Figure 2 As shown, two opposite second roller shafts 1020 are rotatably arranged at the edge of the wire inlet 311, and the second roller shafts 1020 extend along the direction perpendicular to the axial direction of the cavity; the space between the two second roller shafts 1020 is used for the wire bundle to pass through; the two second roller shafts 1020 are also configured to be slidable along the axial direction of the cavity to guide the wire bundle to move along the axial direction of the winding shaft 200. That is, in this embodiment, the wire bundle passes between the two oppositely arranged second roller shafts 1020. During the winding process, the second roller shafts 1020 slide back and forth along the axial direction of the cavity, so that the wire bundle is wound at different positions in the axial direction of the winding shaft 200, making the wire bundle evenly wound on the winding shaft 200. Since the second roller shafts 1020 can rotate, the friction generated when contacting the wire bundle can be reduced, and thus the wear of the wire bundle can be reduced.

[0072] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
