Detailed Implementation

[0021] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers 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 application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0022] Fibers are important reinforcements in composite materials and are widely used in aerospace, automotive, construction, and sporting goods industries. During fiber processing, an adhesive needs to be applied to the outer surface of the fiber to allow it to cure. However, existing technologies suffer from problems such as uneven adhesive application and weak bonding between the adhesive layer and the fiber.

[0023] To address the aforementioned problems, this application provides a fiber processing apparatus, including a fiber unwinding unit, a tension adjusting unit, a coating unit, a drying unit, and a shearing unit. The fiber unwinding unit unwinds the fibers from the fiber shaft; the tension adjusting unit adjusts the tension of the fibers; the coating unit applies adhesive multiple times to the surface of the fibers to ensure uniform coating; the drying unit performs gradient drying on the adhesive-coated fibers; and the shearing unit cuts the gradient-dried fibers. This ensures a uniform adhesive layer on the surface of the processed fibers and a tight bond between the adhesive and the fibers, guaranteeing the stability of the fiber quality.

[0024] like Figure 1In the illustrated embodiment, a fiber processing device includes a de-firing unit 1, a tension adjustment unit 2, a coating unit 3, a drying unit 4, and a shearing unit 5. The de-firing unit 1 includes a de-firing frame 11 and multiple de-firing shafts 12. In one example, the de-firing frame 11 can be welded from multiple square tubes; in other examples, the de-firing frame 11 can be integrally formed, and the material of the de-firing frame 11 can be aluminum alloy. The bottom of the de-firing frame 11 is equipped with leveling feet or moving rollers to facilitate installation, positioning, and subsequent maintenance. The de-firing shafts 12 are mounted on the de-firing frame 11 via mounting shafts. The mounting shafts can be welded to the de-firing frame 11. The de-firing shafts 12 are coaxially sleeved on the mounting shafts and can rotate relative to the mounting shafts. Fiber shafts are correspondingly sleeved on the de-firing shafts 12, and the fiber shafts de-fiber while rotating. The fiber shafts can be secured to the de-firing shafts 12, for example, by providing retaining rings on the de-firing shafts 12. The retaining rings can secure the fiber shafts, facilitating both installation and disassembly. The multiple unwinding shafts 12 are parallel to each other, which can ensure that the fiber filaments drawn out from each fiber shaft are in the same direction, which is beneficial to the subsequent processing of the fiber filaments.

[0025] like Figure 1 As shown, the tension adjustment unit 2 includes a tension adjustment frame 21 and multiple tension adjustment rollers 22. The tension adjustment frame 21 can be made of aluminum alloy profiles or welded steel structures, and the overall tension adjustment frame 21 is frame-like. The two ends of the multiple tension adjustment rollers 22 are rotatably mounted on the tension adjustment frame 21 via bearing seats, and the multiple tension adjustment rollers 22 are parallel to each other. The fiber filaments are sequentially wound around and pass through the multiple tension adjustment rollers 22. In one example, a moving unit is provided, which is connected to the multiple tension adjustment rollers 22 to drive each tension adjustment roller 22 to move, thereby adjusting the distance between adjacent tension adjustment rollers 22. When the distance between adjacent tension adjustment rollers 22 increases, the tension of the fiber filaments increases; when the distance between adjacent tension adjustment rollers 22 decreases, the tension of the fiber filaments decreases. Therefore, the tension adjustment rollers 22 allow the fiber filaments to enter the next process with a constant and suitable tension. A tension sensor 23 can be installed on the tension adjustment frame 21 to detect the tension of the fiber filaments, so as to understand the tension status of the fiber filaments in a timely manner. A vision sensor 24 can also be installed on the tension adjustment frame 21 to detect the status of the fiber filaments in real time and prevent multiple fiber filaments from getting tangled.

[0026] like Figure 2As shown, the coating unit 3 includes a coating frame 31, a coating pipe 32, a first coating ring 33, and a second coating ring 34. The coating frame 31 is made of aluminum alloy profiles or welded steel structure, and the overall structure of the coating frame 31 is frame-like, providing a stable and precise installation foundation for the coating pipe 32, the first coating ring 33, and the second coating ring 34. The coating pipe 32 is fixedly installed on the coating frame 31. The coating pipe 32 can be installed on the coating frame 31 by welding or by connecting parts. The coating pipe 32 is used to transport adhesive. An adhesive storage tank 36 can be installed at the bottom of the coating frame 31, and the adhesive in the adhesive storage tank 36 is pumped into the coating pipe 32 by a delivery pump.

[0027] A first coating ring 33 is disposed on a coating pipe 32 and is connected to the coating pipe 32 by welding. The first coating ring 33 is annular and has a first cavity that communicates with the coating pipe 32 to receive adhesive from the coating pipe 32. The inner ring of the first coating ring 33 has multiple first outlet holes, through which the adhesive in the first cavity can flow out. When the fiber passes through the first coating ring 33, the adhesive is coated on the surface of the fiber. The first coating ring 33 provides a precise and uniform initial coating for the fiber.

[0028] The second coating ring 34 is disposed on the coating pipe 32. The second coating ring 34 can be connected to the coating pipe 32 by welding. The second coating ring 34 is cylindrical, and the central axis of the second coating ring 34 is the same as the transmission direction of the fiber, which facilitates the fiber to pass through the middle of the second coating ring 34. A second cavity is provided inside the second coating ring 34, and the second cavity is connected to the coating pipe 32. The adhesive in the coating pipe 32 can enter the second coating ring 34. The inner ring of the second coating ring 34 is provided with a second liquid outlet hole, and the second liquid outlet hole is evenly distributed in the inner ring of the second coating ring 34. Therefore, the adhesive can flow out to the surface of the fiber through the second liquid outlet hole. In addition, the cylindrical second coating ring 34 can avoid over-coating and ensure the uniformity of the coating adhesive. The area of ​​the second liquid outlet is larger than that of the first liquid outlet. This allows the fiber filament to pass through the first coating ring 33 for initial coating, and then through the second coating ring 34 for secondary coating with adhesive. This enables the adhesive to fully penetrate into the fiber filament and form a uniform adhesive layer on the surface of the fiber filament.

[0029] like Figure 1 As shown, the drying unit 4 is used to perform gradient drying on the fibers coated with adhesive. For example, multiple drying units 4 can be set, each with a different temperature. When the fibers pass through multiple drying units 4 in sequence, the drying units 4 at different temperatures can perform gradient drying on the fibers, avoiding burning the fibers due to excessively high temperatures or incomplete drying due to excessively low temperatures.

[0030] like Figure 1 The shearing unit 5 shown is used to cut the fiber filaments after gradient drying. It can cut the fiber filaments into finished products of fixed length or into finished products of different lengths.

[0031] In one example, such as Figure 1 As shown, a controller 7 can also be set up, which is electrically connected to the unwinding unit 1, the tension adjustment unit 2, the coating unit 3, the drying unit 4 and the shearing unit 5 respectively, so as to precisely control the opening and closing of each unit.

[0032] In some embodiments, such as Figure 1 and Figure 3 As shown, the fiber processing device also includes a conveying unit 6, which is located between the drying unit 4 and the shearing unit 5. The conveying unit 6 can be a conveyor belt or a conveyor roller, and it is used to convey the dried fiber filaments to the shearing unit 5.

[0033] In some embodiments, such as Figure 3 As shown, the conveying unit 6 includes a conveying frame 61, an upper conveying roller 62, and a lower conveying roller 63. The conveying frame 61 is made of aluminum alloy profiles or welded steel structure and is arranged in a frame-like manner. The two ends of the upper conveying roller 62 are rotatably mounted on the conveying frame 61 via bearing seats, and the lower conveying roller 63 is rotatably mounted on the conveying frame 61 via bearing seats. The upper conveying roller 62 and the lower conveying roller 63 are respectively located on both sides of the fiber conveying path, and the line connecting the central axes of the upper conveying roller 62 and the lower conveying roller 63 is perpendicular to the fiber conveying direction. In one example, the fiber is conveyed laterally in the horizontal direction, the upper conveying roller 62 is located above the lower conveying roller 63, and the fiber passes between the upper conveying roller 62 and the lower conveying roller 63. The corresponding upper conveying roller 62 and lower conveying roller 63 are referred to as conveying roller groups. There are multiple conveying roller groups, which are arranged along the transmission direction of the fiber filaments to facilitate the transmission of the fiber filaments along the transmission direction of the fiber filaments. When the fiber filaments pass through, at least one of the upper conveying roller 62 or the lower conveying roller 63 rotates to drive the fiber filaments to move, thereby achieving the purpose of conveying the fiber filaments.

[0034] In some embodiments, such as Figure 3As shown, the conveying unit 6 also includes a moving component 64, which is mounted on the conveying frame 61 and connected to multiple upper conveying rollers 62. The moving component 64 drives the upper conveying rollers 62 away from or towards multiple lower conveying rollers 63. In one example, the ends of the multiple upper conveying rollers 62 are rotatably mounted on a connecting plate. The moving component 64 can be a cylinder; the fixed part of the cylinder is bolted to the conveying frame 61, and the telescopic part of the cylinder is bolted to the connecting plate. The cylinder extends and retracts to simultaneously adjust the position of the multiple upper conveying rollers 62. When the diameter of the fiber is large, the moving component 64 can drive the upper conveying rollers 62 away from the lower conveying rollers 63, so that the distance between the upper and lower conveying rollers 62 accommodates the larger diameter fiber. When the diameter of the fiber is small, the moving component 64 can drive the upper conveying rollers 62 towards the lower conveying rollers 63, so that the distance between the upper and lower conveying rollers 62 accommodates the smaller diameter fiber.

[0035] In some embodiments, such as Figure 1 As shown, the shearing unit 5 includes a shearing frame 51 and a cutter 52. The shearing frame 51 is made of aluminum alloy profiles or welded steel structure and is arranged in a frame configuration. A shearing platform is provided on the shearing frame 51, which is parallel to the fiber transmission direction. The fiber moves along the shearing platform, which is made of a wear-resistant and smooth material and provides a support surface for the fiber. The cutter 52 is slidably mounted on the shearing frame 51 perpendicular to the fiber transmission direction and moves in a direction perpendicular to the fiber transmission direction to cut the fiber. A cylinder or motor can be used to drive the cutter 52 to move and cut the fiber. The cutting frequency of the cutter 52 is f = v / L, where v is the fiber transmission speed and L is the length of the finished product to be cut.

[0036] In some embodiments, such as Figure 1 As shown, the unwinding unit 1 also includes multiple fiber separating rods 13. The fiber separating rods 13 are located between the unwinding shaft 12 and the tension adjusting unit 2. The multiple fiber separating rods 13 are evenly spaced on the unwinding frame 11 along the direction perpendicular to the fiber transmission direction. The fiber filaments are correspondingly passed between adjacent fiber separating rods 13 to achieve the separation of multiple fiber filaments. In one example, the fiber separating rods 13 are set on the unwinding frame 11 near the tension adjusting frame 21 by a support rod. The length direction of the support rod is perpendicular to the fiber transmission direction. The multiple fiber separating rods 13 are evenly arranged on the support rod along the length direction of the support rod. The support rod can be set to the unwinding frame 11 by welding, and the fiber separating rods 13 are also set to the support rod by welding. The setting of the fiber separating rods 13 facilitates the even separation of multiple fiber filaments, which is convenient for subsequent processing of the fiber filaments.

[0037] In some embodiments, such as Figure 2As shown, the coating unit 3 also includes a hot air duct 35, which is welded onto the coating frame 31 and is used to transport hot air. In one example, a fan is provided at one end of the hot air duct 35 to provide an air source. A heating wire is provided on the hot air duct 35 to heat the air source. Multiple spray holes are provided on the hot air duct 35, and the spray holes correspond to the first coating ring 33 and the second coating ring 34, respectively, for spraying hot air onto the fiber filaments coated with adhesive to initially cure the fiber filaments.

[0038] In some embodiments, such as Figure 1 As shown, the drying unit 4 includes a preheating zone 41, a heating zone 42, and a cooling zone 43. The fiber filaments pass through these zones sequentially. The drying unit 4 includes a first heating block and a second heating block corresponding to the preheating zone 41 and the heating zone 42, respectively. Heating wires are installed in both the first and second heating blocks for heating. The fiber filaments are heated by passing through both heating blocks during transport. The temperature of the second heating block is higher than that of the first heating block, meaning the temperature of the heating zone 42 is higher than that of the preheating zone 41. The temperature of the first heating block is 180℃-200℃, and the temperature of the second heating block is 210℃-230℃. This ensures gradient temperature rise and curing of the fiber filaments after adhesive coating, preventing cracking and blistering caused by sudden heating, while also ensuring sufficient curing of the adhesive and improving the bonding strength between the coating and the fiber. After heating, the fiber filaments enter the cooling zone 43, which is cooled by circulating cold water.

[0039] In some embodiments, such as Figure 1 As shown, the unwinding shafts 12 are arranged on both sides of the unwinding frame 11, which are symmetrically arranged on both sides of the unwinding frame 11, and the unwinding shafts 12 are evenly arranged on both sides of the unwinding frame 11. The axial direction of the unwinding shafts 12 is perpendicular to the transmission direction of the fiber, which can ensure that the fiber is smoothly drawn out in a straight line when the fiber shaft rotates.

[0040] This application also provides a fiber processing method, applied to the fiber processing apparatus described above, combined with... Figures 1 to 3 As shown, the fiber processing methods include: S1: The fiber shaft is fitted onto the unwinding shaft of the unwinding unit to unwind the fibers on the fiber shaft.

[0041] In step S1, the spool-shaped fiber shaft is sleeved on the unwinding shaft 12 so that the fiber shaft can rotate and one end of the fiber filament is led out. At the same time, the fiber shaft rotates to realize the unwinding process of the fiber filament.

[0042] S2: The fiber filaments are sequentially wound around the tension adjusting roller passing through the tension adjusting unit to adjust the tension of the fiber filaments.

[0043] In step S2, the position of the tension adjusting rollers 22 can be moved. When it is necessary to increase the tension of the fiber filaments, the position of the tension adjusting rollers 22 is moved, increasing the distance between the tension adjusting rollers 22. Therefore, the winding trajectory of the fiber filaments between the tension adjusting rollers 22 is lengthened, increasing the tension of the fiber filaments. When it is necessary to decrease the tension of the fiber filaments, the position of the tension adjusting rollers 22 is moved, decreasing the distance between the tension adjusting rollers 22. Therefore, the winding trajectory of the fiber filaments between the tension adjusting rollers 22 is shortened, reducing the tension of the fiber filaments. In this step, adjusting the tension of the fiber filaments prepares for subsequent processes, ensuring that the fiber filaments are in a taut and stable state.

[0044] S3: Pass the fiber filament with adjusted tension through the first coating ring of the coating unit, apply preliminary adhesive to the fiber filament through the first liquid outlet, and then pass the pre-coated fiber filament through the second coating ring of the coating unit, apply secondary adhesive to the pre-coated fiber filament through the second liquid outlet.

[0045] In step S3, the tension-adjusted fiber filaments are passed through the first coating ring 33 of the coating unit 3. The coating pipe 32 delivers adhesive to the first coating ring 33. The adhesive seeps out evenly through the first outlet hole in the inner ring of the first coating ring 33, contacting and adhering to the fiber filament surface, thus achieving preliminary adhesive coating. A thin base adhesive layer is formed on the fiber filament surface, laying a uniform foundation for subsequent secondary adhesive coating. Simultaneously, it can initially fill the tiny pores on the fiber filament surface, improving the bonding between the adhesive and the fiber filament. The fiber filaments, having completed the preliminary adhesive coating, continue to pass through the second coating ring 34 along the transmission path. The coating pipe 32 simultaneously delivers adhesive to the second coating ring 34. The adhesive seeps out through the second outlet hole and covers the surface of the base adhesive layer. Because the area of ​​the second outlet hole is larger than that of the first outlet hole, under the same adhesive delivery pressure, the amount of adhesive delivered by the second coating ring 34 is greater than that by the first coating ring 33, which can fully replenish the base adhesive layer, ensuring the adhesive layer thickness meets the preset requirements. Meanwhile, the second coating can repair defects such as uneven coating or missed coating that may exist in the initial coating process, further improving the integrity and uniformity of the coating.

[0046] S4: The fiber filaments that have been coated with adhesive twice are passed through a drying unit to perform gradient drying on the fiber filaments.

[0047] In step S4, the coated fibers pass through the drying unit 4, which is equipped with different temperature zones so that the fibers pass through different temperature zones in sequence to achieve gradual curing and shaping of the adhesive layer.

[0048] S5: The dried fiber filaments are conveyed to the shearing unit to cut the dried fiber filaments.

[0049] In step S5, the cured fiber filaments are cut to obtain finished fiber filament products that meet the requirements.

[0050] This application provides a fiber processing method, which includes the following steps: Multiple fiber shafts are fixed to the corresponding unwinding shaft 12. The fiber shafts rotate while guiding the fiber filaments to move along the transmission direction to complete the unwinding process.

[0051] Multiple fiber filaments are passed sequentially between adjacent fiber separators 13, which separate the multiple fiber filaments and prevent them from tangling together.

[0052] Multiple fiber filaments are sequentially wound around the tension adjusting roller 22. The state of the fiber filaments is observed in real time by the vision sensor 24 installed on the tension adjusting frame 21, and the tension of the fiber filaments is understood in real time by the tension sensor 23 installed on the tension adjusting frame 21, so as to adjust the position of the tension adjusting roller 22 in a timely manner, thereby adjusting the tension of the fiber filaments and ensuring that the fiber filaments are in a taut and stable state.

[0053] The tension-adjusted fiber filaments pass sequentially through the first coating ring 33 and the second coating ring 34. Upon passing through the first coating ring 33, the fiber filaments undergo preliminary adhesive coating. Upon passing through the second coating ring 34, the fiber filaments undergo further adhesive coating to ensure the adhesive is evenly applied to the surface of the fiber filaments. After passing through the first and second coating rings 33 and 34, hot air is immediately blown onto the adhesive-coated fiber filaments through the hot air duct 35 to initially cure the adhesive, forming a film and preventing it from flowing and accumulating, thus improving the stability of the bond between the adhesive layer and the fiber filaments.

[0054] The fiber filaments with the adhesive layer are passed through the preheating zone 41, heating zone 42 and cooling zone 43 of the drying unit 4 in sequence. The temperature is gradually increased to gently dehydrate and fully cure the adhesive layer, and then the temperature is steadily reduced to set the shape of the adhesive layer, ensuring the bonding strength between the adhesive layer and the fiber filaments and the surface smoothness.

[0055] The shearing unit 5 shears the cured fiber filaments. The shearing frequency of the cutter 52 can be adjusted according to the requirements to obtain the finished fiber filament product that meets the requirements.
