[0038] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be arbitrarily combined with each other.

[0039] In the carbon fiber production process, samples need to be taken and analyzed. In related technologies, manual sampling is often used. However, there are individual differences in the operating techniques of different operators, and the operation stability of the same operator in different samplings is difficult to guarantee. This will lead to differences in the samples obtained. These differences in samples will cause detection errors in subsequent testing, interfere with the accurate judgment of the production process status, and affect the optimization and adjustment of the production process.

[0040] Reference Figures 1 to 5 As shown, this application provides a sampling device for winding sample wire onto a winding drum 7. Figure 1 and Figure 4 As shown, the sampling device includes a support base 1, a resin impregnation assembly 2, a winding assembly 3, an adjustment assembly 4, and a cutting assembly 5. The resin impregnation assembly 2 impregnates the sample filament, which is then wound onto a winding drum 7 located in the winding assembly 3. The winding assembly 3 fixes the winding drum 7 and rotates it, simultaneously completing the winding process. After winding, the cutting assembly 5 cuts the sample filament. The cross-sectional radius of the winding assembly 3 can be adjusted by the adjustment assembly 4 to accommodate winding drums 7 with different inner diameters. The sampling operation of this device is entirely performed by the device itself, minimizing manual intervention, ensuring uniformity in the sampling process, avoiding differences in samples due to operational variations during manual sampling, and ensuring sampling accuracy.

[0041] The support base 1 serves as the basic load-bearing structure of the device. The material of the support base 1 can be high-strength metal or sheet metal. The support base 1 can be manufactured through a single-piece molding process or by connecting multiple components. This ensures the stability of the entire device structure.

[0042] The impregnation assembly 2 is mounted on the support base 1. The impregnation assembly 2 can be fixedly mounted on the support base 1 to ensure its stability; alternatively, it can be detachably mounted on the support base 1 for easy replacement, cleaning, or maintenance. In one example, the impregnation assembly 2 is welded to the support base 1; in another example, it is bolted to the support base 1; and in still other examples, it is mounted to the support base 1 using slots and blocks. The impregnation assembly 2 is trough-shaped and used to hold the adhesive solution for impregnating the sample wire.

[0043] The winding assembly 3 includes a rotating shaft 31 and multiple support members 32. The rotating shaft 31 is rotatably mounted on a support base 1. A motor 33 can be mounted on the support base 1 to drive the rotation of the rotating shaft 31. The support members 32 are all elongated strips, and all support members 32 are parallel to the axis of the rotating shaft 31. The length of each support member 32 is less than or equal to the length of the rotating shaft 31 to avoid affecting the positional changes of the support members 32. The multiple support members 32 are located circumferentially outside the rotating shaft 31 via an adjusting assembly 4. In one example, the multiple support members 32 can be evenly distributed circumferentially outside the rotating shaft 31; in other examples, they can be randomly distributed circumferentially outside the rotating shaft 31. The multiple support members 32 are equidistant from the central axis of the rotating shaft 31. The adjusting assembly 4 is located between the support members 32 and the rotating shaft 31, and connects both the support members 32 and the rotating shaft 31. The distance between the support members 32 and the rotating shaft 31 can be adjusted by the adjusting assembly 4, allowing the support members 32 to move closer to or further away from the rotating shaft 31.

[0044] The winding cylinder 7 is sleeved on the outside of multiple support members 32, with the support members 32 abutting against the inner wall of the winding cylinder 7. The multiple support members 32 provide support and fixation for the winding cylinder 7, thus facilitating the winding of the sample filament after impregnation onto the winding cylinder 7. Operating the adjustment assembly 4 moves the support members 32 radially inward along the rotating shaft 31. When the support members 32 are close to the rotating shaft 31, the winding cylinder 7 can be installed or replaced on the support members 32. Operating the adjustment assembly 4 moves the support members 32 radially outward along the rotating shaft 31. When the support members 32 are away from the rotating shaft 31, they abut against the inner wall of the winding cylinder 7, and the multiple support members 32 fix the winding cylinder 7 in place. Furthermore, since the position of the support members 32 can be varied, it can be applied to winding cylinders 7 with different inner diameters, making this device suitable for sampling operations of different specifications. The rotating shaft 31 rotates along the central axis, causing the adjusting component 4 to rotate. The adjusting component 4 causes the support 32 to rotate, and the support 32 causes the winding drum 7 to rotate, so as to wind the sample wire onto the winding drum 7.

[0045] The number of winding components 3 can be flexibly set, such as... Figure 1 and Figure 2In the example shown, two winding components 3 are provided, located at different positions on the support base 1, and the two winding components 3 do not affect each other. Providing two winding components 3 can speed up the sampling process, or ensure that if one winding component 3 is damaged, the other winding component 3 will not affect its use.

[0046] The adjusting assembly 4 includes a movable part 41 and multiple connecting parts 42. The movable part 41 is cylindrical and can be sleeved on the outside of the rotating shaft 31, and can slide along the axial direction of the rotating shaft 31. Each connecting part 42 corresponds to a support part 32, i.e., one connecting part 42 corresponds to one support part 32. The connecting part 42 can be rod-shaped, with one end hinged to the movable part 41 and the other end hinged to the corresponding support part 32. When the movable part 41 slides along the axial direction of the rotating shaft 31, it drives the connecting part 42 to move, causing the angle between the connecting part 42 and the axis of the rotating shaft 31 to change. When the angle increases, the connecting part 42 drives the support part 32 away from the rotating shaft 31; when the angle decreases, the connecting part 42 drives the support part 32 closer to the rotating shaft 31.

[0047] In one example, a screw hole can be provided on the cylindrical movable part 41 along the radial direction of the movable part 41, and a bolt is provided at the screw hole. Tightening the bolt can move the bolt along the direction of the screw hole. When the bolt is away from the rotating shaft 31, the position of the movable part 41 can be adjusted so that the movable part 41 slides along the rotating shaft 31. When the bolt abuts against the rotating shaft 31, the movable part 41 is fixed, so the adjusting component 4 is fixed. At this time, the rotating shaft 31 can drive the adjusting component 4 and the winding drum 7 to rotate.

[0048] In such Figure 5 In the example shown, three adjustment components 4 are provided. Two of the adjustment components 4 have parallel connecting parts 42, and the third adjustment component 4 is mirrored in shape with one of the adjustment components 4. Of course, in other examples, all three connecting parts 42 can be parallel to each other. As long as the numerical distance between the two ends of all connecting parts 42 is the same when the position of the movable part 41 is moved, that is, the support part 32 is always parallel to the axis of the rotating shaft 31, it is acceptable.

[0049] When there are multiple adjusting components 4, the position of only one movable part 41 can be adjusted. The support member 32, the rotating shaft 31, and the connecting parts 42 of adjacent adjusting components 4 form a parallelogram-like shape. Therefore, when one movable part 41 is moved, the movable part 41 drives the connecting part 42 connected to it to move, the connecting part 42 drives the support member 32 to move, and simultaneously the support member 32 drives the other connecting parts 42 to move. The arrangement of multiple adjusting components 4 not only allows for adjustment of the distance between the support members 32 but also ensures that the support members 32 are axially parallel to the rotating shaft 31.

[0050] The shearing assembly 5 is disposed on the support base 1. Depending on the position of the sample filament wound on the winding drum 7, the shearing assembly 5 can slide along the axial direction of the rotating shaft 31 to cut the sample filament. For example, during the process of the sample filament being wound from one end to the other of the winding drum 7, the shearing assembly 5 can move along with the sample filament and cut it. The shearing assembly 5 can be slidably disposed via a slider rail structure or via a drive cylinder structure.

[0051] When using the sampling device of this application, one end of the sample wire is fixed to the winding drum 7. The sample wire can be fixed here by adhesive. The winding assembly 3 drives the winding drum 7 to rotate, while the sample wire is impregnated with adhesive and wound on the winding drum 7. After the sample wire is cut, the winding drum 7 can be removed to test the winding drum 7 and the sample wire.

[0052] The sampling device of this application can be precisely controlled by preset mechanical structure fixed parameters. For example, by controlling the rotation speed of the rotating shaft 31, the speed of the sample wire winding can be precisely controlled, and the time of sample wire impregnation with glue can also be controlled, which ensures the uniformity of the sampling process and avoids the difference in sampled samples caused by differences in operation during manual sampling, thus ensuring the accuracy of sampling.

[0053] In some embodiments, the sampling device further includes a guide assembly 6, which is disposed on the support base 1. The guide assembly 6 guides the glue-impregnated sample filament along the axial direction of the rotating shaft 31. After passing through the guide assembly 6, the sample filament is wound onto the winding drum 7. The guide assembly 6 combs the sample filament to prevent it from becoming tangled, and also further evens out the glue on the surface of the sample filament, preventing uneven glue application. Figure 1 and Figure 2 In the example shown, two guide components 6 can be set, with the two guide components 6 located on both sides of the winding component 3 respectively. During the sampling process, one of the guide components 6 is selected to guide the sample wire. The setting of two guide components 6 can facilitate guiding the sample wire from different directions, which is flexible.

[0054] In some embodiments, the guide assembly 6 includes a guide rod 61 and a guide block 62, wherein the guide rod 61 is disposed on the support base 1, such as Figures 1-3 In the example shown, both ends of the guide rod 61 are fixed to the support base 1. The guide rod 61 and the support base 1 can be fixed by welding or by bolts. The length direction of the guide rod 61 is the same as the axial direction of the rotating shaft 31. The guide block 62 can be block-shaped and slide along one side of the guide rod 61, or it can be... Figure 1 and Figure 2The guide block 62 shown is cylindrical and slides on the outside of the guide rod 61. The outer wall of the guide block 62 is recessed inward to form a smooth guide groove 621. The sample wire can slide through the guide groove 621 and move towards the winding drum 7. In this application, the position of the guide block 62 can move with the position of the sample wire winding on the winding drum 7 to better guide the sample wire.

[0055] In some embodiments, the surface of the guide groove 621 is set as a smooth curved surface, which can not only protect the sample wire and prevent it from being damaged, but also does not affect the sliding of the sample wire.

[0056] In some embodiments, the shearing component 5 is disposed on the support base 1 via the guide component 6, that is, the shearing component 5 is disposed on the guide component 6. Since the guide component 6 can follow the movement of the sample wire, when it is necessary to cut the sample wire, the shearing component 5 is just close to the sample wire, and can cut the sample wire in time. The shearing component 5 includes a cutter 51, such as Figure 1 and Figure 2 In the example shown, each shearing assembly 5 includes two cutters 51, which are slidably mounted on both sides of the guide groove 621 on the guide block 62. Normally, the sample wire slides through the guide groove 621. When cutting is required, the two cutters 51 move closer together to cut the sample wire. In other examples, the two cutters 51 may also be rotatably mounted on the guide block 62. The sliding or rotating of the cutters 51 can be done manually or by using a drive cylinder to drive the movement of the cutters 51. The shearing assembly 5, relying on the guide assembly 6, can maintain close proximity to the sample wire at all times, ensuring precise cutting timing and avoiding cutting errors caused by sample wire deviation.

[0057] In some embodiments, the impregnation assembly 2 includes an impregnation tank 21 and a guide rod 22. The impregnation tank 21 is located below the winding assembly 3 and contains adhesive. The impregnation tank 21 is disposed on the support base 1, wherein the impregnation tank 21 can be fixed to the support base 1 by welding to ensure the stability of the impregnation tank 21 and prevent the internal adhesive from spilling. The impregnation tank 21 can also be detachably disposed on the support base 1 by screwing or snap-fitting, which facilitates the maintenance or cleaning of the impregnation tank 21. In some examples, a drain port can also be provided on the side wall of the impregnation tank 21 to facilitate the drainage of the internal adhesive. The guide rod 22 is parallel to the axial direction of the rotating shaft 31 along its length. The guide rod 22 is positioned inside the impregnation tank 21, with both ends fixed to the inner walls of the tank. The guide rod 22 is located at the lower part of the tank, allowing a sample wire to pass between the bottom of the guide rod 22 and the bottom wall of the tank. The sample wire contacts the guide rod 22 from the bottom and slides, ensuring that the sample wire can be immersed in the adhesive. Alternatively, the guide rod 22 can be located in the middle or upper part of the tank, as long as the adhesive level in the tank is higher than the guide rod 22.

[0058] In some embodiments, the side of the support member 32 closest to the winding cylinder 7 is a curved surface, which is adapted to the shape of the inner wall of the winding cylinder 7. The curved surface of the support member 32 can be arc-shaped, with the radius of curvature of the arc perfectly matching the radius of curvature of the inner wall of the winding cylinder 7. Only the portion of the support member 32 connected to the slider retains a planar structure. The curved surface ensures that the entire outer side of the support member 32 is in contact with the inner wall of the winding cylinder 7, increasing the contact area. This not only enhances stability when fixing the winding cylinder 7 but also prevents damage to the winding cylinder 7.

[0059] In some embodiments, the support members 32 are evenly distributed radially outward from the rotating shaft 31. For example... Figure 4 In the example shown, there are four support members 32, which are distributed at equal 90° intervals around the center of the cross-section of the shaft 31. The uniform distribution of the support members 32 ensures that the winding drum 7 is subjected to balanced forces and avoids local deformation.

[0060] In some embodiments, the sidewall of the support member 32 that contacts the winding drum 7 is provided with an elastic buffer pad. The buffer pad can be made of either silicone or rubber. The elasticity of the buffer pad can fill the tiny gap between the support member 32 and the inner wall of the winding drum 7. Furthermore, anti-slip textures can be provided on the surface of the buffer pad to increase friction and prevent the winding drum 7 from slipping when it rotates.

[0061] In some embodiments, the support base 1 includes a handle 11, a horizontal plate 12, and two vertical plates 13. The two vertical plates 13 are fixed parallel to each other at the top of both ends of the horizontal plate 12, making the cross-section of the horizontal plate 12 and the two vertical plates 13 U-shaped. The impregnation assembly 2 is disposed within the space enclosed by the horizontal plate 12 and the two vertical plates 13, such as... Figure 1 In the example shown, the two ends of the dipped assembly 2 are fixed to the two vertical plates 13 respectively, and the bottom of the dipped assembly 2 is fixed to the horizontal plate 12. The fixing method is welding or screwing. Along the radial direction of the rotating shaft 31, the height of the two vertical plates 13 is higher than the height of the dipped assembly 2, and the rotating shaft 31 is set at a position on the vertical plates 13 higher than the dipped assembly 2. In some examples, a winding assembly 3 can be provided, wherein one end of the rotating shaft 31 of the winding assembly 3 is set on the vertical plate 13, as in... Figure 1 and Figure 2 In the example shown, two winding components 3 are provided, one on each of the two upright plates 13. In one example, the handle 11 can be fixedly mounted on the bottom of the horizontal plate 12 or on one of the upright plates 13. The fixing method can be welding or screwing. The handle 11 is provided for easy gripping. Of course, the handle 11 can also be omitted to reduce the weight of the device.
