Description

Technical Field

[0001] This application relates to the field of weaving apparatus technology, and more specifically, to a carbon fiber cloth weaving apparatus. Background Technology

[0002] Carbon fiber cloth is a unidirectional carbon fiber reinforcement product characterized by high strength, low density, thinness, and minimal increase in the self-weight and cross-sectional dimensions of the reinforced component. It is suitable for reinforcement and repair of various structural types and components. Carbon fiber cloth is used for tensile, shear, and seismic reinforcement of structural components. When used with a matching impregnating adhesive, it forms a carbon fiber composite material, creating a complete and high-performance carbon fiber sheet reinforcement system. This system is suitable for addressing issues such as increased building loads, changes in engineering function, material aging, concrete strength below design values, and structural crack repair. Since carbon fibers are at a high temperature after weaving, cooling is necessary after weaving to prevent them from sticking together during winding. Traditional cooling methods often involve placement, which is inefficient. To improve this, a carbon fiber cloth weaving device is proposed.

[0003] As disclosed in the patent announcement CN221625298U, a carbon fiber cloth weaving and winding device includes a support plate. A guide frame is fixedly connected to the upper middle part of the support plate. A guide roller is provided on the inner side wall of the guide frame. A mounting frame is fixedly connected to the upper end of the support plate and to the right of the guide frame. A support shaft is movably connected to the inner wall of the mounting frame. A winding wheel is fixedly sleeved on the outer side of the support shaft. A replacement mechanism is provided on the mounting frame. Four evenly distributed mounting seats are fixedly connected to the lower end of the support plate. A roller is provided on the inner side of each mounting seat.

[0004] Although it achieves the goal of moving the end plate away from the mounting bracket by pulling it to disengage the limiting plate from the insert plate, the limiting plate can be limited by the action of the locking hole, locking ball and other structures, so that the operator can pull the servo motor to drive the protrusion to disengage from the support shaft, which is convenient for the replacement of the winding wheel.

[0005] However, the existing weaving device does not solve the problem that it is not convenient to use the reciprocating air blowing to dissipate heat from the carbon fiber fabric, nor is it conducive to the elastic pressing and winding of the fabric and the speed of fabric cooling. This affects the cooling effect of the carbon fiber fabric and the quality of the fabric winding. Utility Model Content

[0006] The purpose of this invention is to provide a carbon fiber cloth weaving device to solve the problems mentioned in the background art, such as the inconvenience of reciprocating air blowing to dissipate heat from the carbon fiber cloth, the disadvantage of elastic pressing and winding of the cloth and accelerating the cooling speed of the cloth, which affect the cooling effect of the carbon fiber cloth and the quality of the cloth winding.

[0007] To address the technical problems mentioned in the background section above, some embodiments of this application provide a carbon fiber cloth weaving device, including a weaving machine and a winding frame. The winding frame is provided on one side of the weaving machine, and an auxiliary frame is installed at the top of the winding frame. Integrated frames are symmetrically arranged on the outer wall of the weaving machine. Bidirectional lead screws are movably installed inside each integrated frame. A stepper motor is provided at the top of each integrated frame, and the output end of the stepper motor is connected to the bidirectional lead screw.

[0008] Furthermore, the surface of the bidirectional lead screw is fitted with two sets of threaded sleeves, and the threaded sleeves are threadedly connected to the bidirectional lead screw.

[0009] Furthermore, a connecting plate is installed between the two sets of corresponding threaded sleeves, and an integrated plate is provided on the side of the connecting plates that are close to each other.

[0010] Furthermore, a servo motor is installed at the center of the top of each integrated board, and a drive shaft is installed at the output end of each servo motor, with gears fitted on the surface of each drive shaft.

[0011] Furthermore, sliders are provided at the top of the integrated boards on both sides of the servo motor, and the sliders are slidably connected to the integrated boards.

[0012] Furthermore, each slider has a rack on the side closest to the gear, and the rack meshes with the gear.

[0013] Furthermore, each slider is equipped with a jet frame at its top, and the jet frame is connected to an external air source via a flexible hose.

[0014] Furthermore, a winding motor is installed on the side wall of the winding frame, and a winding roller is installed at the output end of the winding motor, and the winding roller is movably connected to the winding frame.

[0015] Furthermore, the auxiliary frame has symmetrically slidingly mounted limit blocks inside, and an auxiliary roller is movably mounted between the two sets of limit blocks.

[0016] Furthermore, each of the limiting blocks is equipped with a pull rod at its top, and the surface of each pull rod is provided with a spring, with the upper and lower ends of the spring connected to the auxiliary frame and the limiting block, respectively.

[0017] Compared with the prior art, the beneficial effects of this utility model are: the weaving device not only realizes the convenient reciprocating swing blowing to dissipate heat from the carbon fiber fabric, which facilitates the elastic pressing and winding of the fabric and accelerates the cooling speed of the fabric, but also improves the heat dissipation and cooling effect of the carbon fiber fabric and the quality of the fabric winding.

[0018] The carbon fiber fabric is woven by a braiding machine. After weaving, the fabric is at a high temperature. It is then pulled from between two sets of integrated plates to the surface of the take-up roller and fixed there. A take-up motor drives the take-up roller to rotate, which in turn winds the carbon fiber fabric. During this winding process, to rapidly cool the fabric, an external air source sprays air through a flexible hose from a jet cooling frame onto both the top and bottom surfaces of the fabric. A stepper motor drives a bidirectional lead screw to rotate, which in turn moves two sets of threaded sleeves closer together. These sleeves then move the connecting plate. The integrated board and the air jet frame are brought close together so that the air jet frame is close to the surface of the carbon fiber fabric for better air cooling. A servo motor drives a gear through a drive shaft to rotate, and a rack drives the air jet frame to move. Under the reciprocating drive of the servo motor, the air jet frame moves back and forth, thereby reciprocating and blowing air onto the carbon fiber fabric to increase the uniformity of contact between the carbon fiber fabric and the air, and to accelerate the cooling speed of the fabric. This achieves convenient reciprocating and blowing air to dissipate heat from the carbon fiber fabric, which facilitates the acceleration of fabric cooling and improves the cooling effect of air blowing.

[0019] During the winding process of carbon fiber fabric by the take-up roller, as more and more fabric is applied to the surface of the take-up roller, the diameter of the fabric also increases. At this point, the fabric will come into contact with the surface of the auxiliary roller and drive the auxiliary roller to rotate. The fabric roll drives the auxiliary roller to move upward, and the limit block drives the pull rod to retract and squeeze the spring. With the elastic cooperation of the spring, the spring provides a reverse force to the auxiliary roller, so that the auxiliary roller always presses against the surface of the fabric roll, making the fabric roll more tightly wound and improving its winding effect.

[0035] Please see Figures 1 to 6 This utility model provides an embodiment of a carbon fiber cloth weaving device, including a weaving machine 1 and a winding frame 2. The winding frame 2 is provided on one side of the weaving machine 1, and an auxiliary frame 3 is installed on the top of the winding frame 2. Integrated frames 4 are symmetrically arranged on the outer wall of the weaving machine 1. Bidirectional lead screws 9 are movably installed inside the integrated frames 4. Stepper motors 7 are provided on the top of the integrated frames 4. The stepper motors 7 play a power driving role, and the output end of the stepper motors 7 is connected to the bidirectional lead screws 9. Two sets of threaded sleeves 8 are fitted on the surface of the bidirectional lead screws 9, and the threaded sleeves 8 are threadedly connected to the bidirectional lead screws 9. A connecting plate 5 is installed between the two sets of corresponding threaded sleeves 8. An integrated plate 6 is provided on the side of the connecting plates 5 that are close to each other.

[0036] A servo motor 10 is installed at the center of the top of the integrated board 6. The servo motor 10 serves as a power drive. The output end of the servo motor 10 is equipped with a drive shaft 21, and the surface of the drive shaft 21 is fitted with gears 11.

[0037] The top of the integrated board 6 on both sides of the servo motor 10 is provided with a slider 13, and the slider 13 is slidably connected to the integrated board 6. The side of the slider 13 near the gear 11 is provided with a rack 12, and the rack 12 meshes with the gear 11.

[0038] Each slider 13 is equipped with a jet mount 14 at its top, and the jet mount 14 is connected to an external air source via a flexible hose.

[0039] The carbon fiber fabric threads are introduced into the braiding machine 1 for weaving. After weaving, the carbon fiber fabric is at a high temperature. At this point, the carbon fiber fabric is pulled from between the two integrated plates 6 to the surface of the take-up roller 16 and fixed to the surface of the take-up roller 16. The take-up motor 15 is turned on, and the take-up roller 16 is rotated by the take-up motor 15, which in turn rotates the carbon fiber fabric. During the winding process, in order to quickly cool the fabric, an external air source is turned on. The external air source sprays air through a flexible hose from the jet frame 14, which sprays air from both the top and bottom surfaces of the carbon fiber fabric to cool it. At the same time, the stepper motor 7 is turned on, and the stepper motor 7 drives the bidirectional lead screw 9 to rotate. With the bidirectional lead screw 9 threadedly connected to the threaded sleeve 8, the bidirectional lead screw 9 drives the two sets of threaded sleeves 8 to move closer to each other, and the threaded sleeves rotate to cool the fabric. The sleeve 8 drives the connecting plate 5, the integrated plate 6, and the air jet frame 14 to move closer together, so that the air jet frame 14 is close to the surface of the carbon fiber cloth, so as to better cool the carbon fiber cloth with air. The servo motor 10 is turned on, and the servo motor 10 drives the gear 11 to rotate through the drive shaft 21. Under the mutual meshing of the gear 11 and the rack 12, and the sliding cooperation between the slider 13 and the integrated plate 6, the rack 12 drives the air jet frame 14 to move. Under the reciprocating drive of the servo motor 10, the servo motor 10 drives the air jet frame 14 to move back and forth, thereby reciprocating and blowing air on the carbon fiber cloth to increase the uniformity of the contact between the carbon fiber cloth and the air, and to accelerate the cooling speed of the cloth. This realizes convenient reciprocating and blowing air to dissipate heat from the carbon fiber cloth, which facilitates the cooling speed of the cloth and improves the cooling effect of air blowing.

[0040] A winding motor 15 is installed on the side wall of the winding frame 2. The winding motor 15 serves as a power drive. A winding roller 16 is installed at the output end of the winding motor 15, and the winding roller 16 is movably connected to the winding frame 2.

[0041] The auxiliary frame 3 has symmetrical sliding limit blocks 18 installed inside, and an auxiliary roller 17 is movably installed between the two sets of limit blocks 18. Each limit block 18 has a pull rod 20 installed at its top, and each pull rod 20 has a spring 19 on its surface. The upper and lower ends of the spring 19 are respectively connected to the auxiliary frame 3 and the limit block 18.

[0042] During the winding process of the carbon fiber fabric by the take-up roller 16, as more and more fabric is applied to the surface of the take-up roller 16, the diameter of the fabric also increases. At this time, the fabric will contact the surface of the auxiliary roller 17 and drive the auxiliary roller 17 to rotate. Under the sliding cooperation of the limiting block 18 and the auxiliary frame 3, the fabric roll drives the auxiliary roller 17 to move upward. The limiting block 18 drives the pull rod 20 to retract and squeeze the spring 19. Under the elastic cooperation of the spring 19, the spring 19 provides a reverse force to the auxiliary roller 17, so that the auxiliary roller 17 always presses against the surface of the fabric roll, making the fabric roll more tightly wound and improving its winding effect.

[0043] Working principle: Carbon fiber fabric threads are introduced into the braiding machine 1 for weaving. After weaving, the carbon fiber fabric is at a high temperature. The fabric is then pulled from between the two integrated plates 6 to the surface of the take-up roller 16 and fixed thereon. The take-up motor 15 drives the take-up roller 16 to rotate, which in turn winds the carbon fiber fabric. During winding, to rapidly cool the fabric, an external air source is activated, spraying air through a flexible hose from the jet frame 14. The jet frame 14 cools the carbon fiber fabric from both the top and bottom surfaces. A stepper motor 7 drives a bidirectional lead screw 9 to rotate, which in turn moves two sets of threaded sleeves 8 closer together. These sleeves, in turn, move the connecting plate 5, integrated plate 6, and jet frame 14 closer together, bringing the jet frame 14 closer to the surface of the carbon fiber fabric for better air cooling. A servo motor 10 drives a gear 1 via a drive shaft 21. 1. Rotation of the rack 12 drives the air jet frame 14 to move. Under the reciprocating drive of the servo motor 10, the servo motor 10 drives the air jet frame 14 to move back and forth, thereby reciprocating and blowing air onto the carbon fiber fabric to increase the uniformity of the carbon fiber fabric's contact with the air and accelerate the cooling speed of the fabric. During the winding process of the take-up roller 16, as more and more fabric is on the surface of the take-up roller 16, its diameter also becomes larger and larger. At this time, the fabric will contact the surface of the auxiliary roller 17 and drive the auxiliary roller 17 to rotate. Under the sliding cooperation of the limit block 18 and the auxiliary frame 3, the fabric roll drives the auxiliary roller 17 to move upward. The limit block 18 drives the pull rod 20 to retract and squeeze the spring 19. Under the elastic cooperation of the spring 19, the spring 19 provides a reverse force to the auxiliary roller 17, so that the auxiliary roller 17 always presses against the surface of the fabric roll, making the fabric roll more tightly wound. The above is the complete usage of the carbon fiber fabric weaving device.
