[0031] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. In the following description, when referring to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this invention. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this invention as detailed in the appended claims.

[0032] In related technologies, when using fiber products for the prefabrication of the trailing edge UD forming process of wind turbine blades, the sizing agent in the fiber products often migrates due to unstable bonding with the fiber products. Although sizing agent migration does not affect the performance of the blades, the migrated sizing agent needs to be removed in subsequent production processes. This additional removal process not only increases the labor and material costs of subsequent processes but also reduces production efficiency to some extent due to the increased complexity of subsequent operations.

[0033] In order to solve the problems existing in the related technologies, in the exemplary embodiments of this disclosure, a fiber processing system is provided, including a baking device for baking pre-formed fiber products.

[0034] like Figure 1 As shown, the baking apparatus includes multiple placement platforms 1 and an adjustment assembly connected to the multiple placement platforms 1. The adjustment assembly is used to adjust the spacing between adjacent placement platforms 1 and the length or width of any one placement platform 1.

[0035] The baking device can be configured in various ways, but it must ensure that the fiber product can be placed inside for baking without damaging its original structure. The baking device in this embodiment can bake any fiber product. The baking device can be an electrically heated baking device.

[0036] In one example, the fiber product is monoaxial glass fiber (i.e., uniaxial glass fiber), but it could also be carbon fiber. When baking the monoaxial glass fiber, the spacing between the placement platforms 1 in the baking apparatus and the length or width of each platform 1 need to be adjusted first. Adjusting the spacing between each platform 1 ensures that the monoaxial glass fibers on each platform 1 do not contact each other, while adjusting the length or width of each platform 1 allows for the placement of different numbers of monoaxial glass fibers on each platform 1.

[0037] In one exemplary embodiment, the placement stage 1 is configured with an adjustable width. When the number of uniaxial glass fibers to be processed is large, the width of the placement stage 1 can be increased to accommodate more fibers; when the number of uniaxial glass fibers to be processed is small, the width of the placement stage 1 can be decreased to prevent collisions between the uniaxial glass fibers due to excessive movement. It is important to note that the uniaxial glass fibers need to be placed orderly on each placement stage 1 to prevent them from being compressed and to avoid disrupting the internal fiber arrangement, which could alter the anisotropic mechanical properties of the uniaxial glass fibers. Simultaneously, avoiding stacking and compressing the uniaxial glass fibers also facilitates uniform heat transfer during baking, preventing uneven distribution of the sizing agent on the surface of the uniaxial glass fibers and thus preserving the risk of sizing agent migration.

[0038] In another embodiment, the placement stage 1 is configured to be length-adjustable. When the length of the uniaxial glass fiber to be processed changes, the length of the placement stage 1 can be adjusted to ensure that the length of the placement stage 1 matches the length of the glass fiber.

[0039] In one exemplary embodiment, such as Figure 1 As shown, the baking apparatus includes a cavity 9, multiple placement platforms 1, and adjustment components, all disposed within the cavity 9. A flexible buffer layer 3 is provided on a portion of the inner wall of the cavity 9. The flexible buffer layer 3 can be one or more, and can be disposed on any inner wall of the cavity 9. When placing fiber products, the presence of the flexible buffer layer 3 protects the fiber products from damage caused by impact with the inner wall of the cavity 9.

[0040] In one example, such as Figure 1 As shown, two flexible buffer layers 3 are provided. Both flexible buffer layers 3 are arranged perpendicular to the trajectory direction of the fiber product being placed into the cavity 9, and the two flexible buffer layers 3 are respectively fixed to the inner walls of the cavity 9 on both sides in this direction. This design method ensures that even if the fiber product shakes from side to side when placed into the cavity 9, it will not be damaged by impacting the inner wall of the cavity 9.

[0041] like Figure 2As shown, the baking device also includes a heating component 2, which includes a circulating fan 21, an indoor fan 22 and a heat pump 23. The indoor fan 22 is connected to the heat pump 23. The circulating fan 21 and the indoor fan 22 are disposed in the cavity 9, and the heat pump 23 is disposed outside the cavity 9.

[0042] This structural design enables efficient heat transfer and circulation. The heat generated by the heat pump 23 is transferred to the cavity 9 through the indoor fan 22, and then circulated inside the cavity 9 by the circulating fan 21, making the temperature inside the cavity 9 more uniform, thereby improving the baking effect of the fiber products.

[0043] In one example, the cavity 9 is also provided with a door (not shown in the figure). When the door is open, it is convenient to place fiber products into the cavity 9. When the door is closed, it can ensure that the baking process in the cavity 9 is not affected by the external environment, thereby improving the baking effect.

[0044] In one exemplary embodiment, such as Figure 1 and Figure 2 As shown, a heat insulation board 4 is installed on part of the inner wall of the cavity 9. The heat insulation board 4 effectively reduces heat loss and improves energy efficiency. The heat insulation board 4 effectively prevents heat from escaping through the walls of the cavity 9, allowing the heat inside the cavity 9 to be better used for baking fiber products, thus reducing energy consumption.

[0045] In one example, insulation plates 4 are provided on all six inner walls of the cavity 9, and the insulation plates 4 are located in the layer closest to the inner wall of the cavity 9. For example, when a flexible buffer layer 3 is also provided on the same inner wall, the flexible buffer layer 3 will be placed on the insulation plate 4, so that the insulation plate 4 is located between the inner wall of the cavity 9 and the flexible buffer layer 3.

[0046] In one exemplary embodiment, the baking apparatus further includes a controller (not shown) electrically connected to the heating component 2 and the circulating fan 21, and the baking apparatus further includes a humidifier 5 electrically connected to the controller.

[0047] The controller is electrically connected to the heating component 2 and the circulating fan 21, enabling precise control of these components to accurately regulate the temperature within the cavity 9. The humidifier 5 is also electrically connected to the controller, which can add an appropriate amount of water to the cavity 9 according to the baking process requirements, thus adjusting the humidity environment within the cavity 9. For example, in the baking process of certain fiber products, specific temperature and humidity conditions are required. The controller can then control the heating component 2 and the humidifier 5 to start or stop based on preset temperature and humidity parameters, maintaining the humidity within the cavity 9 within a suitable range to ensure the baking quality of the fiber products.

[0048] In one exemplary embodiment, such as Figure 1 and Figure 2 As shown, the baking device also includes a dehumidifier 6, which is electrically connected to the controller. During the baking process of the fiber products, when the humidity inside the cavity 9 is too high, the controller can activate the dehumidifier 6 to remove excess moisture and ensure that the humidity inside the cavity 9 meets the baking process requirements. Through the coordinated control of the humidifier 5 and the dehumidifier 6 by the controller, precise adjustment of the humidity inside the cavity 9 can be achieved to meet the baking needs of different fiber products.

[0049] In one exemplary embodiment, such as Figure 3 and Figure 4 As shown, the adjustment assembly includes a first adjustment part 7 and a second adjustment part 8. The first adjustment part 7 is used to adjust the spacing between adjacent placement platforms 1, and the second adjustment part 8 is used to adjust the length or width of the placement platform 1.

[0050] The specific structure of the first adjustment section 7 and the second adjustment section 8 can be arbitrarily set according to the actual situation. By setting the first adjustment section 7 and the second adjustment section 8 with clear division of labor, the adjustment components can adjust the placement platform 1 more flexibly and accurately to adapt to fiber products of different sizes and shapes.

[0051] In one exemplary embodiment, such as Figure 3 As shown, the first adjustment unit 7 includes a slide rail 71, a slider 72 and a drive mechanism 73. The slider 72 is slidably mounted on the slide rail 71 and connected to the power output end of the drive mechanism 73 and the placement platform 1.

[0052] Adjacent placement platforms 1 are mounted on different sliders 72, which can slide freely on slide rails 71. The distance between adjacent placement platforms 1 can be adjusted by driving the sliders 72 along the slide rails 71 via a drive mechanism 73. The drive mechanism 73 can be any device capable of moving the sliders 72.

[0053] The number of sliders 72 can be set to multiple based on the number of placement platforms 1, so as to ensure that each placement platform 1 can be independently adjusted in position.

[0054] In one example, such as Figure 1 and Figure 2 As shown, there are four placement platforms 1, which are divided into two groups arranged horizontally in the cavity 9. The two placement platforms 1 in each group are arranged back and forth along the longitudinal direction of the cavity 9. There are two first adjustment parts 7, which correspond to the two groups of placement platforms 1 respectively.

[0055] Taking one of the first adjustment parts 7 as an example, its structure is described. Two slide rails 71 are provided, namely a first slide rail and a second slide rail, which are horizontally arranged on the inner walls of the cavity 9 on both sides, perpendicular to the longitudinal direction of the cavity 9. Each slide rail 71 has two sliders 72. The sliders 72 in the first slide rail are the first and second sliders, and the sliders 72 in the second slide rail are the third and fourth sliders. Two placement platforms 1 are fixed on the corresponding sliders 72 in the two slide rails 71. Specifically, one placement platform 1 is fixed on the first and third sliders, and the other placement platform 1 is fixed on the second and fourth sliders. Two drive mechanisms 73 are provided, namely a first drive structure and a second drive mechanism, which are located at both ends of the first slide rail. The first drive mechanism is used to adjust the position of the first slider, and the second drive mechanism is used to adjust the position of the second slider.

[0056] In actual use, the position of the first slider on the first slide rail can be adjusted by the first driving mechanism, and the position of the second slider on the first slide rail can be adjusted by the second driving mechanism, thereby changing the position of the corresponding placement platform 1, so that the two placement platforms 1 located on the same horizontal plane move closer or further apart, thus achieving the purpose of changing the distance between the placement platforms 1.

[0057] In one exemplary embodiment, such as Figure 3 As shown, the drive mechanism 73 includes a drive motor 731 and a lead screw 732. The drive motor 731 is fixed on the slide rail 71. One end of the lead screw 732 is fixedly connected to the drive motor 731, and the other end passes through the slider 72 and is threadedly connected to the slider 72. When the drive motor 731 is started, the power output shaft of the drive motor 731 drives the lead screw 732 to rotate. The rotation of the lead screw 732 is converted into linear movement of the slider 72 on the slide rail 71 through threaded transmission, thereby driving the placement platform 1 to move and realizing the adjustment of the distance between adjacent placement platforms 1. When it is necessary to change the movement direction of the slider 72, the movement direction of the slider 72 can be changed by changing the rotation direction of the power output shaft of the drive motor 731.

[0058] In one example, the drive motor 731 is electrically connected to the controller. When it is necessary to adjust the spacing between adjacent placement platforms 1, the controller can control the operating state of the drive motor 731, thereby causing the placement platform 1 to move.

[0059] In one exemplary embodiment, such as Figure 4 As shown, the second adjustment part 8 includes a telescopic bracket, which is fixed on the placement platform 1 and is used to adjust the length or width of the placement platform 1.

[0060] The structure of the telescopic bracket can be of any form. In this embodiment, the telescopic bracket includes a first fixing part 81, a second fixing part 82, and a telescopic connecting rod 83. The first fixing part 81 and the second fixing part 82 are respectively fixed to the two ends of the placement platform 1 in the telescopic direction. The two ends of the telescopic connecting rod 83 are respectively fixedly connected to the first fixing part 81 and the second fixing part 82. By changing the length of the telescopic connecting rod 83, the length or width of the placement platform 1 can be changed.

[0061] In one exemplary embodiment, such as Figure 1 and Figure 4 As shown, the placement platform 1 includes multiple placement plates 11, which are detachably connected to each other via connectors 13 and connection through holes 12 formed thereon.

[0062] The placement platform 1 consists of multiple placement plates 11, each with a connecting through hole 12. The multiple placement plates 11 are connected to the connecting through holes 12 via connectors 13. Each placement plate 11 can slide within the connecting hole, allowing the placement platform 1 to be extended and retracted to change its length or width. Two ends of a telescopic bracket are fixed to the placement plates 11 at the far ends of the placement platform 1. By changing the length of the telescopic bracket, the placement plates 11 can be moved.

[0063] The connector 13 can take many forms. In this embodiment, the connector 13 is a bolt and a nut. The bolt, nut and connecting through hole 12 can be used to fix and loosen multiple placement plates 11.

[0064] In one example, such as Figure 4 As shown, the placement platform 1 consists of two placement plates 11, which are connected by connecting through holes 12, bolts, and nuts. The two ends of a telescopic bracket are connected to the two placement plates 11 respectively, and the telescopic bracket is located below the placement plates 11. When the area of ​​the placement platform 1 needs to be increased, the bolts and nuts are loosened, and the telescopic bracket is extended to increase the width of the placement plate 11. After adjusting to the appropriate width, the bolts and nuts are tightened to fix the placement plate 11. Conversely, when the area of ​​the placement platform 1 needs to be decreased, the telescopic bracket is shortened to decrease the width of the placement plate 11.

[0065] In one exemplary embodiment, the fiber treatment system further includes an impregnation device and a forming device, the impregnation device being located at a pre-process stage of the baking device and the forming device being located at a post-process stage of the baking device.

[0066] The impregnation and forming devices can be arbitrarily set according to the products being produced. In actual production, the fiber products are first impregnated by the impregnation device to ensure that the impregnation liquid is fully integrated into the fiber products; then they pass through the baking device to remove moisture from the fiber products and optimize the bonding effect between the fiber products and the impregnation liquid; finally, they pass through the forming device to shape the fiber products for subsequent production.
