However, the compaction roller in the existing technology can only lay fiber bundles on molds with small variations in flatness and curvature. In the existing technology, the shapes of various components are becoming increasingly complex, and there are even cases where the shape changes drastically in some areas. Due to the drastic changes in shape, the laying strength requirements of the fiber bundles are higher, and more types of fiber bundles need to be laid. The fiber laying devices in the existing technology cannot meet the above laying requirements. Summary of the Invention

[0020] Compared with the prior art, this application has the following beneficial effects:

[0021] This application includes a frame, on which a material storage assembly and a guiding assembly are disposed; the frame also includes a sliding frame and a drive module, the drive module being connected to the sliding frame to control the height of the sliding frame; the frame further includes a fiber feeding assembly and a compaction assembly, the fiber feeding assembly pulling the fiber bundle led out from the guiding assembly and inputting the fiber bundle into the next stage process; the frame also includes a compaction assembly, which is disposed on the sliding frame, and the fiber bundle is laid on the fiber laying surface after passing through the compaction assembly;

The compaction assembly squeezes the fiber bundle and lays it on the fiber laying surface. Since the entire fiber feeding device and the compaction assembly are both set on the sliding frame;

[0023] Compared with the prior art, firstly, because the height of the sliding frame of this application is adjustable, it can ensure that the distance between the compaction component and the fiber laying surface remains stable, thereby ensuring that the fiber bundle is subjected to uniform pressure, which is beneficial to improving the fiber laying quality;

[0024] Secondly, since the height of the sliding frame is adjustable, this application can also flexibly adjust the position of the sliding frame according to actual needs, thereby applying different laying pressures to the fiber bundles to meet different laying requirements and improve the quality of fiber laying; especially for some areas with large changes in height or shape, this application can also make quick adjustments as needed and quickly switch between different laying pressures, thereby achieving localized reinforced laying and improving the laying quality of complex areas.

[0025] Finally, by replacing different types of guide components, different types of fiber bundles can be laid, thus improving the applicability of the equipment. Attached Figure Description

[0039] Implementation Method 1

[0040] Reference Figure 1 and Figure 7 This embodiment, as an optional embodiment of this application, discloses a fiber laying device, including a frame 1. A material storage assembly is provided on the frame 1. The material storage assembly includes an air shaft 3 and a recovery roller 4. One end of the air shaft 3 is rotatably connected to the frame 1 through a roller bearing, and the other end is connected to an external air source through a rotary joint. The air shaft 3 is used to install the fiber bundle roller.

[0041] One section of the recycling roller 4 is rotatably connected to the frame 1 via a rolling bearing. A recycling disc is provided on the recycling roller 4. A magnetic damper 5 and a pulley 6 are also provided at the end of the recycling roller 4 connected to the frame 1. A pulley 6 is provided at the end of the air shaft 3 connected to the frame 1. The two pulleys 6 are connected to each other via a transmission belt 7.

[0042] The above settings not only enable the simultaneous release of fiber bundles and waste recycling, but also ensure the stable operation of the equipment through the magnetic damper 5.

[0043] A guiding assembly is also provided on the frame 1. The guiding assembly includes a first guiding wheel 8, a reversing wheel 9, a second guiding wheel 10, and a guide 11. The first guiding wheel 8, the reversing wheel 9, the second guiding wheel 10, and the guide 11 are arranged sequentially along the direction of fiber bundle movement.

[0044] The first guide wheel 8, the reversing wheel 9, and the second guide wheel 10 are all rotatably mounted on the frame 1 via a rotating shaft and a rolling bearing. The first guide wheel 8, the reversing wheel 9, and the second guide wheel 10 are all provided with limit grooves, and their surfaces are also provided with an anti-stick coating.

[0045] A sliding frame 2 is also provided on the lower side of the frame 1. Slider blocks 13 are provided on both sides of the sliding frame 2, and slide rails 12 are provided on both sides of the frame 1. Each slider 13 is slidably connected to the slide rail 12 on the corresponding side, thereby realizing the sliding connection between the sliding frame 2 and the frame 1. A drive module is also provided on the frame 1. The drive module includes a drive cylinder 14. The telescopic shaft of the drive cylinder 14 is connected to the sliding frame 2 to control the height of the sliding frame 2.

[0046] The guide 11 includes an upper guide plate 1101 and a lower guide plate 1102. The upper guide plate 1101 and the lower guide plate 1102 are arranged opposite each other. A gap is also provided between the upper guide plate 1101 and the lower guide plate 1102. This gap is a guide gap for the fiber bundle to pass through and enter the next process.

[0047] The bottom of the frame 1 is also provided with a compaction assembly, which includes a compaction roller 15. The compaction roller 15 is rotatably connected to the sliding frame 2 through a rotating shaft and roller bearings. At the same time, the compaction surface of the compaction roller 15 is tangent to the guide gap to avoid the fiber bundle from contacting the edge of the upper guide plate 1101 and thus damaging the fiber bundle.

[0048] The filament laying device also includes a filament feeding device, which includes a feeding motor 16, a feeding roller 17 and a base. The base is connected to the sliding frame 2. A reducer is also provided on the base. The output shaft of the feeding motor 16 is poweredly connected to the reducer. The feeding roller 17 is rotatably mounted on the upper guide plate 1101 through a rotating shaft and rolling bearing.

[0049] The output shaft of the reducer is equipped with a synchronous belt pulley 18, and one end of the shaft connected to the feeding roller 17 is also equipped with a synchronous belt pulley 18. The two synchronous belt pulleys 18 are connected by the synchronous belt 18 to realize power transmission. At the same time, the wire feeding assembly also includes a feeding pressing assembly, which includes a pressing mounting base 19. A pressing cylinder 20 is provided on the pressing mounting base 19. A pressing bracket 21 is provided on the telescopic shaft of the pressing cylinder 20. The pressing bracket 21 is rotatably connected to a rotating shaft through a rolling bearing. The rotating shaft is connected to a pressing roller 22. The pressing mounting base 19 is provided on the sliding frame 2.

[0050] A through hole is provided on the lower guide plate 1102, and the pressing roller 22 passes through the through hole. Along the direction perpendicular to the movement of the fiber bundle, the feeding roller 17 and the pressing roller 22 are respectively arranged on both sides of the fiber bundle and face each other; thereby clamping the fiber bundle from the upper and lower sides respectively.

[0051] The position of the pressing roller 22 can be adjusted by the pressing cylinder 20, thereby controlling the distance between the feeding roller 17 and the pressing roller 22. This not only adjusts the pressure on the fiber bundle to meet the clamping requirements of fiber bundles of different specifications, but also facilitates the early debugging of the equipment.

[0052] The wire feeding assembly also includes a tension cylinder 23 and a swing rod 24. The tension cylinder 23 is disposed on the base, and the swing rod 24 is rotatably disposed on the base. One end of the swing rod 24 is hinged to the tension cylinder 23, and the other end is rotatably disposed with an adjusting roller 25, which is in contact with the synchronous belt 18.

[0053] The extension and retraction of the tension cylinder 23 can drive the swing arm 24 to rotate, which in turn drives the adjusting roller 25 to move toward or away from the synchronous belt 18, thereby adjusting the tension of the synchronous belt 18 and ensuring the stability and reliability of the transmission.

[0054] The fiber laying device further includes a shearing assembly, which includes a shearing mounting base 26 disposed on the sliding frame 2. A shearing cylinder 27 is disposed on the shearing mounting base 26. A cutter 28 and a clamping head 29 are mounted on the output shaft of the shearing cylinder 27. Along the direction of fiber bundle movement, the cutter 28 is located at the front end of the clamping head 29. The shearing assembly also includes a shearing anvil 30 and a clamping anvil 31. A groove is provided on the upper guide plate 1101, and the shearing anvil 30 and the clamping anvil 31 are embedded in the groove.

[0055] After installation, the cutting edge of the cutter 28 is 0.05-0.2mm higher than the clamping surface of the clamping head 29, so as to ensure that the cutter 28 cuts the fiber bundle first and then clamps the fiber bundle. This not only ensures that the fiber bundle is in a taut state during cutting, but also that it is clamped and kept in a taut state in time after cutting, thus creating a foundation for subsequent fiber feeding.

[0056] The cutting anvil 30 is directly opposite the cutting knife 28, and the clamping anvil 31 is directly opposite the clamping head 29. The cutting anvil 30 is made of steel or other metal materials with high hardness.

[0057] The aforementioned shearing device can cut the fiber bundles in time after the laying is completed, thereby enabling switching between different work stations and improving laying efficiency.

[0058] The fiber laying device also includes a heating bracket 32, which is connected to the sliding frame 2. The sliding frame 2 is equipped with an infrared radiator 33 and a temperature sensor 34. The heating end of the infrared radiator 33 is directly facing the fiber bundle to heat the fiber bundle and improve the laying quality. At the same time, the temperature sensor 34 monitors the temperature of the fiber bundle and improves the temperature control accuracy.

[0059] In use, the fiber bundle roller is mounted on an air shaft, which tensions and fixes the fiber bundle roller. The fiber bundle is manually pulled and connected to the compaction roller after passing through the guide assembly and the feeding assembly. At the same time, waste material is wrapped around the recycling roller. Then, the pressing cylinder is activated, which controls the pressing roller to move toward the feeding roller and clamp the fiber bundle.

[0060] Then the feeding motor starts, pulling the fiber bundle toward the compaction roller. At the same time, the entire fiber laying device moves along the fiber laying trajectory under the drive of the external power equipment. The compaction roller moves and squeezes the fiber bundle onto the mold surface.

[0061] When the height of the mold surface changes, the sliding frame is controlled by the drive cylinder to adjust its height position, thereby ensuring that the distance between the compaction roller and the mold surface is stable, thus maintaining the stable pressure on the fiber bundle and improving the quality of fiber laying.

[0062] In areas with drastic changes in shape, the sliding frame of this application can be adjusted in real time according to the changes in shape, thereby meeting the special laying requirements of local areas; at the same time, the pressure on the fiber bundle can be increased by reducing the height of the sliding frame, which has a strong adaptability to local reinforcement laying, can effectively improve the laying quality of local areas, and meet diverse laying requirements.

[0063] Compared with existing technologies, this application has a simple structure and is easy to operate, which helps to simplify the wire laying process.

[0064] The above are merely preferred embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
