Description

Technical Field

[0001] This invention belongs to the field of chemical fiber spinning equipment accessories, specifically, it relates to a fiber separating comb device. Background Technology

[0002] In recent years, the demand for carbon fiber in fields such as wind power, rail transportation, and aerospace has increased, leading to an exceptionally hot carbon fiber industry. Carbon fiber manufacturers are constantly expanding their production capacity, and competition in the entire carbon fiber market is becoming increasingly fierce. Therefore, improving production efficiency and reducing production energy consumption are common business themes for every carbon fiber manufacturer. Increasing the single-line production capacity of carbon fiber inevitably requires increasing the number of filament bundles running on a single line, while also increasing the operating speed of the production line.

[0003] However, as the number of single-filament bundles increases, the phenomena of bundle adhesion and tangling become particularly noticeable during the sizing process in carbon fiber production. Typically, before entering the sizing process, the bundles are separated by a filament-splitting comb device. This device has multiple comb needles fixedly connected to it, spaced radially apart. Each bundle passes through its corresponding interval, and the sidewalls of the comb needles come into contact with some of the misaligned bundles. These misaligned bundles bend at the contact points, changing their direction of extension. This allows the filament-splitting comb device to adjust the misaligned bundles and prevent tangling. When adjacent yarn bundles are too close together, they may overlap and stick together. However, when the yarn bundles are significantly offset, these yarn bundles will bend considerably at the contact point with the comb needles, increasing the number of threads in the yarn bundle. Since the initial yarn output speed of each yarn bundle is the same, the stretching ratio of the yarn bundle increases accordingly with the increase in threads, leading to the problem of the yarn bundle diameter being too small. Furthermore, the pressure between the offset yarn bundle and the comb needle is greater, resulting in greater friction between the yarn bundle and the sidewall of the comb needle, making the yarn bundle prone to breakage due to excessive wear.

[0004] In view of this, the present invention is proposed. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a filament combing device. By setting a driveable combing needle mechanism, when the position of part of the filament bundle is offset, while ensuring that the filament bundles overlap and stick together, the combing needle mechanism cooperates with the movement or deflection of the filament bundle to reduce the degree of bending of the filament bundle and the friction between the combing needle mechanism and the filament bundle, thereby solving the problems of the offset filament bundle having too small a diameter and being prone to breakage.

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is: a filament combing device, including a main support and a combing needle mechanism disposed on the main support, wherein each filament bundle passes through the gap between the corresponding combing needle mechanism; the combing needle mechanism is movably connected to the main support, or at least part of the combing needle mechanism is elastically deformable, and at least part of each combing needle mechanism can be deflected or moved in the radial direction under the drive of the filament bundle.

[0016] Furthermore, multiple second combing mechanisms are provided within the slide, and each second combing mechanism is arranged along the extension direction of the slide. The sum of the lengths of all combing mechanisms in the extension direction of the slide is less than the length of the slide in the extension direction.

[0017] Alternatively, multiple slides are arranged on the main support, with the extension direction of each slide being basically parallel to the arrangement direction of the slides, and a sliding second comb mechanism is provided in each slide.

[0018] Furthermore, the combing mechanism includes a slider that is slidably disposed in a slide rail, and a wire splitting rod connected to the slider. The length of the slider in the extension direction of the slide rail is greater than the length of the wire splitting rod in the same direction, and the wire splitting rod contacts the wire bundle.

[0039] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0040] In the description of this invention, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, 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 limiting this invention.

[0041] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0042] like Figures 1 to 7 As shown in the embodiment of the present invention, a filament combing device includes a main support 1 and a combing needle mechanism 2 disposed on the main support 1. Each filament bundle 3 passes through the gap between the corresponding combing needle mechanisms 2. The combing needle mechanism 2 is movably connected to the main support 1, or at least part of the combing needle mechanism 2 is elastically deformable. Each combing needle mechanism 2 can move or deflect in the offset direction under the action of the offset filament bundle 3.

[0043] With the above configuration, by setting a movable combing mechanism 2, when the position of a portion of the filament bundle 3 is offset, while ensuring that the corresponding combing mechanism 2 can adjust the extension direction of the filament bundle 3 by contacting the filament bundle 3 to prevent the filament bundle 3 from overlapping and sticking together, the combing mechanism 2 is at least partially moved or deflected to reduce the bending degree of the offset filament bundle 3 and the friction between the combing mechanism 2 and the filament bundle 3, thereby avoiding the problem of the filament bundle 3 having too small a diameter and being prone to breakage due to wear.

[0044] like Figures 1 to 3 and Figure 7 As shown in the embodiment of the present invention, the main support 1 has an installation port 130, and the comb needle mechanism 2 passes through the installation port 130 and is movably mounted on the main support 1 through the installation port 130. Through the cooperation between the installation port 130 and the comb needle mechanism 2, the comb needle mechanism 2 is mounted on the main support 1 with a certain degree of freedom, so that when the yarn bundle 3 is deviated, the comb needle mechanism 2 swings or moves through the cooperation with the installation port 130, thereby reducing the force between the yarn bundle 3 and the comb needle mechanism 2.

[0045] like Figures 1 to 3 As shown, in an embodiment of the present invention, the combing mechanism 2 is a first combing mechanism 210. The first combing mechanism 210 includes a movable part 211 that passes through the mounting opening 130. At least a portion of the peripheral sidewall of the mounting opening 130 is spaced a certain distance from the peripheral sidewall of the movable part 211. The first combing mechanism 210 is swayably mounted on the main support 1 through the movable part 211. By setting a certain distance between a portion of the peripheral sidewall of the mounting opening 130 and the movable part 211 located in the mounting opening 130, when the yarn bundle 3 is squeezed, the movable part 211 can move into the space formed by cooperating with the mounting opening 130, thereby realizing that the first combing mechanism 210 is swayably mounted on the main support 1.

[0046] In an embodiment of the present invention, when the first combing mechanism 210 swings to its maximum angle, the peripheral sidewalls of the movable part 211 near both ends respectively contact the peripheral sidewalls of the corresponding ends of the mounting port 130; so as to limit the maximum swing angle of the first combing mechanism 210 through the cooperation between the movable part 211 and the peripheral sidewalls of the mounting port 130, and prevent the first combing mechanism 210 from swinging too large, which would cause the first combing mechanism 210 to be unable to effectively correct the position of the filament bundle 3.

[0047] In an embodiment of the present invention, the maximum swing angle of the first comb needle mechanism 210 is less than or equal to 20 degrees; more preferably, the maximum swing angle of the first comb needle mechanism 210 is less than 15 degrees; by limiting the maximum swing angle of the first comb needle mechanism 210, the first comb needle mechanism 210 can reduce the wear on the filament bundle 3 by swinging, while preventing the swinging first comb needle mechanism 210 from interfering with the adjacent first comb needle mechanism 210.

[0048] In embodiments of the present invention, the movable part 211 is a column, a platform, or a cone; correspondingly, the mounting port 130 is columnar, and at least one side wall of the mounting port 130 is spaced a certain distance from the movable part 211; or, the mounting port 130 is a platform with a side wall slope that is less than that of the movable part 211.

[0049] In an embodiment of the present invention, the movable part 211 has a rectangular cross-section, and the mounting port 130 is correspondingly configured as a rectangular opening. The two pairs of side walls of the movable part 211 are respectively in contact with the side walls corresponding to the mounting port 130, and the other two side walls are respectively in contact with the side walls corresponding to the mounting port 130.

[0050] In embodiments of the present invention, the movable part 211 is a cylinder, and the mounting port 130 is correspondingly cylindrical, with the diameter of the movable part 211 being smaller than the diameter of the mounting port 130; or the mounting port 130 is an elliptical cylinder, with the diameter of the movable part 211 being smaller than the diameter of the major axis of the mounting port 130.

[0051] In an embodiment of the present invention, a plurality of mounting ports 130 are arranged on the main support 1. The peripheral sidewall of each mounting port 130 near the adjacent mounting port 130 is spaced apart from the peripheral sidewall of the movable part 211 by a certain distance. Since each filament bundle 3 is arranged in the space between the comb needle mechanisms 2, when each filament bundle 3 comes into contact with the comb needle mechanism 2, the direction of the force between the filament bundle 3 and the comb needle mechanism 2 is basically parallel to the arrangement direction of the comb needle mechanism 2. The first comb needle mechanism 210 has at least a degree of freedom to swing parallel to the arrangement direction so that when the filament bundle 3 deviates, the first comb needle mechanism 210 can reduce the bending angle of the filament bundle 3 and the friction between the first comb needle mechanism 210 and the filament bundle 3 by swinging.

[0052] In an embodiment of the present invention, the opening shape of the mounting port 130 is a circular opening, and the diameter of the mounting port 130 is larger than the diameter of the movable part 211.

[0053] In an embodiment of the present invention, the opening shape of the mounting port 130 is an elliptical hole, the major axis direction of the mounting port 130 is substantially parallel to the arrangement direction of the mounting ports 130, the diameter of the mounting port 130 in the major axis direction is larger than the diameter of the movable part 211, and the diameter of the mounting port 130 in the minor axis direction is greater than or equal to the diameter of the movable part 211.

[0054] When the filament bundle 3 deviates, its extension direction has a certain angle with the extension direction of other filament bundles 3, so that its contact position with the first comb needle mechanism 210 is located near the peripheral sidewall of the first comb needle mechanism 210 facing the adjacent first comb needle mechanism 210. That is, the direction of the extrusion force between the filament bundle 3 and the first comb needle mechanism 210 has a certain angle with the arrangement direction of the first comb needle mechanism 210, and the larger the swing angle of the first comb needle mechanism 210, the larger the angle between the two directions. By making the mounting port 130 cooperate with the movable part 211, the movable part 211 has more freedom in the radial direction, so that the swing direction of the first comb needle mechanism 210 is always parallel to the extrusion force between the first comb needle mechanism 210 and the filament bundle 3, thereby improving the flexibility of the first comb needle swing.

[0055] In an embodiment of the present invention, when the first comb needle mechanism 210 swings to its maximum swing angle, the two ends of the first comb needle mechanism 210 are respectively spaced a certain distance from the adjacent first comb needle mechanism 210. Specifically, the length of the mounting port 130 of the main body bracket 1 in the axial direction is less than or equal to 2 mm, the diameter of the mounting port 130 is less than or equal to 2.5 mm, the diameter of the movable part 211 of the first comb needle mechanism 210 is greater than or equal to 1.3 mm, and the interval length between the mounting ports 130 is greater than or equal to 3.6 mm. Preferably, the length of the mounting port 130 in the axial direction is approximately equal to 1.8 mm, the diameter of the mounting port 130 is approximately equal to 2 mm, the diameter of the movable part 211 is approximately equal to 2 mm, and the interval length between the mounting ports 130 is 4 mm. This ensures that the maximum swing angle of each first comb needle mechanism 210 is less than or equal to 20 degrees, preferably 15 degrees.

[0056] In an embodiment of the present invention, the first combing mechanism 210 includes a stop portion 213 connected to one end of the movable portion 211, the length of the stop portion 213 in at least one radial direction being greater than the diameter of the mounting opening 130; and a filament separating portion 212 connected to the other end of the stop portion 213 or the movable portion 211, the filament separating portion 212 contacting the filament bundle 3; the stop portion 213 has limited the first combing mechanism 210 to prevent the first combing mechanism 210 from falling off.

[0057] In an embodiment of the present invention, the side of the stop portion 213 near the mounting port 130 is configured as a smooth curved surface, and the side of the stop portion 213 is in relative movable contact with the peripheral sidewall of one end of the mounting port 130, so that the stop portion 213 rotates more smoothly with the first comb needle mechanism 210.

[0058] In embodiments of the present invention, each mounting opening 130 extends vertically, and a stop portion 213 is disposed above the mounting opening 130 and connects to the peripheral sidewall of the top of the mounting opening 130; the filament splitting portion 212 is connected to the bottom end of the movable portion 211 or to the top end of the stop portion 213; preferably, the filament splitting portion 212 is connected to the bottom end of the movable portion 211, and the filament bundle 3 is located below the main support 1; so that the filament splitting portion 212 also serves as a counterweight for the first comb needle mechanism 210, and the stop portion 213 is stably connected to the top of the peripheral sidewall of the mounting opening 130. The ends are joined together to prevent the first comb needle mechanism 210 from disengaging from the mounting port 130. In addition, the filament splitting part 212 can be kept vertical under the action of gravity. When the filament bundle 3 deviates, the filament bundle 3 causes the filament splitting part 212 to swing. After swinging at a certain angle, the radial component of the gravity of the filament splitting part 212 is equal to the squeezing force between the filament bundle 3 and the filament splitting part 212. The first filament splitting part 212 stays at the current angle, thereby correcting the deviation of the filament bundle 3 while preventing the filament bundle 3 from contacting or separating from the adjacent filament bundle 3 due to excessive swinging.

[0059] like Figure 2 As shown, the stop part 213, the movable part 211 and the splitting part 212 are integrally formed. The stop part 213 is a ring or annular fan-shaped structure that extends from the movable part 211 along an arc.

[0060] like Figure 3 As shown, the movable part 211 and the splitting part 212 are integrally formed. The end of the movable part 211 away from the splitting part 212 protrudes from the mounting opening 130. The stop part 213 is provided on the outer periphery of the movable part 211 and extends outward along the radial direction of the movable part 211. Preferably, the stop part 213 is sleeved on the outer periphery of the movable part 211. Another preferred embodiment is that the stop part 213 and the movable part 211 are integrally formed.

[0061] In embodiments of the present invention, the filament-splitting portion 212 has a columnar or needle-like structure.

[0062] like Figure 4 and 5 As shown, in an embodiment of the present invention, the mounting port 130 is a strip-shaped hole forming a slide 131, and the combing mechanism 2 is a second combing mechanism 220, which is movably disposed within the slide 131. By providing a slidable second combing mechanism 220 on the main support 1, when the yarn bundle 3 shifts and squeezes the second combing mechanism 220, the second combing mechanism 220 slides and adjusts its position under the squeezing of the yarn bundle 3, thereby reducing the bending degree of the yarn bundle 3 and the pressure between it and the second combing mechanism 220.

[0063] In one embodiment of the present invention, a plurality of slides 131 are arranged on the main support 1, and the extension direction of each slide 131 is basically parallel to the arrangement direction of the slides 131. A slidable second combing mechanism 220 is arranged in each slide 131 respectively. This allows each second combing mechanism 220 to be arranged relatively independently, and the interval between the slides 131 keeps a certain distance between each second combing mechanism 220 to prevent adjacent filament bundles 3 from sticking together due to being too close.

[0064] In another preferred embodiment of the present invention, a plurality of second comb needle mechanisms 220 are provided in the slide rail 131. Each second comb needle mechanism 220 is arranged along the extension direction of the slide rail 131. The sum of the lengths of all comb needle mechanisms 220 in the extension direction of the slide rail 131 is less than the length of the slide rail 131 in the extension direction. This allows the plurality of second comb needle mechanisms 220 to be slidably arranged in the same slide rail 131. When one of the second comb needle mechanisms 220 slides, it can push the adjacent second comb needle mechanism 220 to move. This allows the positions of the adjacent second comb needle mechanisms 220 to be adjusted automatically and adaptively, making the use more flexible.

[0065] In an embodiment of the present invention, the combing mechanism 2 includes a slider 221 slidably disposed in a slide rail 131 and a wire-splitting rod 222 connected to the slider 221. The length of the slider 221 in the extension direction of the slide rail 131 is greater than the length of the wire-splitting rod 222 in the same direction. The wire-splitting rod 222 contacts the wire bundle 3. When the slider 221 of the second combing mechanism 220 is in contact with the slider 221 of the adjacent second combing mechanism 220, the wire-splitting rods 222 of the two second combing mechanisms 220 can be set at a certain distance apart to prevent the two wire-splitting rods 222 from being too close and clamping the two sides of the wire bundle 3 located between the two wire-splitting rods 222, which would cause the wire bundle 3 to break due to excessive wear.

[0066] In one embodiment of the present invention, the slider 221 and the main support 1 are magnetically connected, and the slider 221 is slidably disposed in the slide rail 131 by magnetic force.

[0067] like Figure 4 As shown, in another embodiment of the present invention, at least one side wall of the slide 131 is provided with an inwardly recessed groove 132, and the corresponding side of the slider 221 is movably embedded in the groove 132 and slides in contact with the groove wall of the groove 132; preferably, the two pairs of side walls of the slide 131 are respectively provided with inwardly recessed grooves 132; through the cooperation between the groove wall of the groove 132 and the slider 221, the slider 221 is limited to the slide 131.

[0068] In one embodiment of the present invention, the slider 221 includes a main body in the middle and retractable sliding parts disposed on both side walls of the main body. The sliding parts can elastically extend and retract away from the main body. The main body is located in a slide rail 131, and the lead screw 222 is connected to the main body. The width of the slide rail 131 is greater than the length of the main body in the same direction. Each sliding part is located in a corresponding groove 132. Specifically, the width of the slide rail 131 is greater than or equal to the sum of the lengths of the two compressed sliding parts and the main body in the same direction. When installing the second comb needle mechanism 220, the two sliding parts are compressed first to lower the slider 221. The width is then determined, and the slider 221 is placed into the slide rail 131. The sliding part is released, and the sliding part enters the slide groove 132 through its own elasticity, so that the slider 221 is slidably embedded in the slide rail 131 through the sliding part. Preferably, the sliding part itself is compressible. The surface of the sliding part is coated with a coating with a coefficient of friction lower than that of the sliding part to reduce the friction between the slider 221 and the slide groove 132. Another preferred embodiment is that the sliding part includes a first sliding part embedded in the slide groove 132 and a second sliding part disposed between the first sliding part and the main body. The second sliding part is elastic and is a spring.

[0069] In another embodiment of the present invention, the main support 1 has an opening communicating with one end of the slide rail 131, and the slide groove 132 also communicates with the opening; when the second combing mechanism 220 is installed, the slider 221 of the second combing mechanism 220 enters the slide groove 132 and the slide rail 131 through the opening in a shape-fitting manner; by providing an opening on the main support 1 so that the slider 221 of the second combing mechanism 220 enters the slide rail 131 through the opening, it is not necessary to make the slider 221 part into an elastic structure, thereby improving the overall structural strength and durability of the slider 221, preventing the slider 221 from deforming due to aging, which would cause the lead screw 222 to deviate. In the event of a situation; preferably, the main support 1 is provided with a sealing part having a sealing opening; more preferably, the sealing part is welded or bonded to the main support 1; even more preferably, the sealing part is detachably or rotatably connected to the main support 1, so that the sealing opening of the sealing part can be opened and closed; by moving the sealing part away from the opening, the number of second filament combs in the slide 131 can be reduced or increased, so that the number of second filament comb mechanisms provided in the slide 131 of the main support 1 can be adjusted according to actual needs, and when the second filament comb mechanism is damaged, the damaged second filament comb mechanism can be removed and replaced, thereby avoiding the scrapping of the entire filament comb device and reducing maintenance costs.

[0070] like Figure 5As shown, in another embodiment of the present invention, the mounting port 130 constituting the slide 131 is opened upward on the main support 1, and the slider 221 is provided with an overlapping portion 223. The overlapping portion 223 slides in contact with the surface of the main support 1 located around the top of the slide 131, and the slider 221 is slidably mounted on the main support 1 through the overlapping portion 223; the slider 221 is slidably mounted in the slide 131 through the overlapping portion 223 and the main support 1; preferably, the lead screw 222 is connected to the top or bottom of the slider 221.

[0071] In an embodiment of the present invention, each slider 221 is provided with a swing hole, and the dividing screw 222 is inserted into the swing hole from top to bottom. The diameter of the dividing screw 222 is smaller than the diameter of the swing hole. In one assembly method of the dividing screw 222, the dividing screw 222 is provided with a radially expanding expansion portion. The diameter of the expansion portion is larger than the diameter of the swing hole. The expansion portion abuts against the top of the slider 221, and the dividing screw 222 is vertically and swingably mounted on the slider 221 through the expansion portion. This allows the dividing screw 222 to be swingably mounted on the slider 221. When the wire bundle 3 deviates, the dividing screw 222 first swings to reduce the compressive force between the dividing screw 222 and the wire bundle 3. Because the dividing screw 222 tilts, the direction of the force between the dividing screw 222 and the slider 221 deflects to the horizontal direction. The slider 221 then slides, allowing the dividing screw 222 to return to a vertical state. Since the sliding adjustment method of the slider 221 requires... To change the overall movement state of the second comb needle mechanism 220, the second comb needle needs to be gradually accelerated. When the yarn bundle 3 deviates significantly in a short period of time, the slider 221 cannot immediately move to the corresponding position. This results in a large squeezing force between the yarn bundle 3 and the second comb needle mechanism 220 for a period of time, making the yarn bundle 3 prone to breakage during this period. By making the yarn dividing rod 222 swingably set on the slider 221, the yarn dividing rod 222 can quickly respond to the change of the yarn bundle 3 when it deviates, preventing the above situation from occurring. Furthermore, after a period of time, the slider 221 moves to the corresponding position under the action of the yarn dividing rod 222, allowing the yarn dividing rod 222 to return to the vertical state. This ensures that there is no force or the direction of the force between the yarn dividing rod 222 and the yarn bundle 3 is horizontal, so the yarn bundle 3 does not need to bear the force of the yarn dividing rod 222, further preventing the yarn bundle 3 from breaking.

[0072] In embodiments of the present invention, the lead screw 222 has a columnar or needle-like structure.

[0073] like Figure 6As shown, in an embodiment of the present invention, the combing mechanism 2 includes a fixing part 231 connected to the main support 1 and a contact part 232 connected to the fixing part 231. The contact part 232 can be separably contacted with the filament bundle 3. The fixing part 231 and / or the contact part 232 are made of elastically deformable materials. Alternatively, the fixing part 231 and the contact part 232 can be rotatably connected relative to each other. This is to reduce the squeezing force between the filament bundle 3 and the combing mechanism 2 through the elastic deformation of the combing mechanism 2 itself.

[0074] like Figure 7 As shown, in an embodiment of the present invention, a rotating part 140 is provided on the main support 1, and the comb needle mechanism 2 is rotatably connected to the rotating part 140; the rotating part 140 enables the comb needle mechanism 2 to be swayed on the main support 1.

[0075] In one embodiment of the present invention, the rotating part 140 is a rotating groove with a spherical space inside, and one end of the combing mechanism 2 is provided with a spherical protrusion, which is rotatably embedded in the rotating groove in a matching shape.

[0076] In one embodiment of the present invention, the comb needle mechanism 2 is arranged in a vertical direction, and a rotating part 140 is provided on a bottom surface of the main body support 1. The top end of the comb needle mechanism 2 is rotatably connected to the rotating part 140. Preferably, the rotating part 140 includes two support protrusions protruding from a bottom surface of the main body support 1. A horizontal rotating shaft is provided between the protruding ends of the two support protrusions, and the top end of the comb needle mechanism 2 is rotatably sleeved on the rotating shaft so that the comb needle mechanism 2 can be rotatably suspended on the rotating part 140.

[0077] In another preferred embodiment of the present invention, the rotating part 140 is in the shape of a shaft, and the combing needle mechanism 2 is provided with a rotating hole. The combing needle mechanism 2 is rotatably sleeved on the rotating part 140 through the rotating hole. Compared with the previous embodiment, the structure is simpler and easier to install. Moreover, the production cost of the rotating shaft structure is lower. Since the filament combing device is only used as an auxiliary device, it is usually only necessary to meet the usage requirements. This embodiment reduces the cost while meeting the usage requirements through the rotating shaft connection, and is more in line with the requirements.

[0078] Preferably, the rotating part 140 is disposed in the mounting port 130 through which the first comb needle mechanism 210 passes, or the rotating part 140 is disposed in the swing hole through which the wire splitting rod 222 passes.

[0079] In embodiments of the present invention, each comb needle mechanism 2 is arranged along a horizontal direction, and the axis of each rotating part 140 is perpendicular to the arrangement direction of the comb needle mechanism 2; preferably, the axis of each rotating part 140 is parallel to a radial direction of the corresponding mounting port 130 or swing hole.

[0080] In an embodiment of the present invention, the two pairs of sidewalls of the main body support 1 are provided with connecting holes that communicate with the peripheral sidewalls of the mounting port 130. The rotating part 140 passes through the connecting holes into the mounting port 130, and the two ends of the rotating part 140 are respectively located in the corresponding connecting holes; or, the two pairs of sidewalls of the slider 221 are provided with connecting holes that communicate with the peripheral sidewalls of the swing hole. The rotating part 140 passes through the connecting holes into the swing hole, and the two ends of the rotating part 140 are respectively located in the corresponding connecting holes; the shaft-shaped rotating part 140 is supported and fixed in the mounting port 130 or the swing hole by the hole wall of the connecting hole; during installation, the combing mechanism 2 can be first set in the mounting port 130 or the swing hole, and the rotating hole of the combing mechanism 2 can be aligned with the corresponding connecting hole, and then the rotating part 140 can be inserted into the main body support 1 or the slider 221 to realize the assembly of the filament combing device.

[0081] It should be noted that when the lead screw 222 is installed in the swing hole via the rotating part 140, an expansion part can be optionally provided on the lead screw 222.

[0082] like Figures 1 to 7 As shown, in an embodiment of the present invention, the main support 1 includes a support portion 110, on which each comb needle mechanism 2 is arranged and disposed, and each filament bundle 3 is disposed at a distance from the support portion 110; a limiting portion 120 is located between the support portion 110 and the filament bundle 3, with one side of the limiting portion 120 connected to the support portion 110 and extending towards the filament bundle 3 on the opposite side; by setting the limiting portion 120 to limit the filament bundle 3, the filament bundle 3 is prevented from moving too close to the support portion 110, causing the filament bundle 3 to come into contact with the support portion 110; in addition, it prevents the distance between the filament bundle 3 and the swing axis of the comb needle mechanism 2 from being too close, so that when the comb needle mechanism 2 swings to the maximum swing angle, the offset distance of the contact position between the filament bundle 3 and the comb needle mechanism 2 is too short to achieve the effect of reducing the pressure of the filament bundle 3.

[0083] In an embodiment of the present invention, the support portion 110 is a plate-shaped structure, and the plate surface of the support portion 110 is substantially parallel to the arrangement direction of the filament bundle 3; the limiting portion 120 is a plate-shaped structure having a certain angle with the support portion 110, and the edge of the limiting portion 120 near the support portion 110 is connected to one side edge of the support portion 110; preferably, the plate surface of the support portion 110 is parallel to a horizontal plane, and the limiting portion 120 is parallel to a vertical plane; more preferably, the plate surface of the limiting portion 120 is parallel to the arrangement direction of the comb needle mechanism 2.

[0084] In embodiments of the present invention, the comb needle mechanism 2 is arranged in at least one row along a straight line on the support portion 110; preferably, the comb needle mechanism 2 is arranged in at least two rows along a straight line on the support portion 110; and the comb needle mechanisms 2 are staggered on the support portion 110.

[0085] It should be noted that the filament bundle of the present invention can be not only large-tow carbon fiber, but also various types of carbon fiber from 1K to 50K. It is also applicable to dry-jet wet-spun carbon fiber, wet-spun carbon fiber, and carbon fiber with different flexibility under different sizing agent conditions.
