Description

Technical Field

[0001] The invention relates to the technical field of SiC fiber preparation, and in particular to a device and method for automatically laying a sulfuric acid paper tape on a winding wheel. Background Art

[0002] With the rapid development of aviation and aerospace industries, the service conditions of various equipment have become more stringent, so higher and more requirements are placed on materials. It is difficult for a single material system to meet the needs. Continuous monofilament SiC fiber is a high-tech product with the advantages of high specific strength, high specific modulus, corrosion resistance, wear resistance, good thermal stability, etc. It is used to reinforce various matrices such as resins, metals and ceramics. At present, SiC fiber is used as a reinforcing phase to prepare magnesium-based composite satellite detection platforms, titanium-based composite integral blade rings, low-pressure turbine shafts, fiber-reinforced silicon carbide fairings and other composite structural parts. It is an important type of high-tech structural material and has clear application prospects in the aerospace industry.

[0003] Continuous, large-diameter single-filament SiC fibers are produced using chemical vapor deposition, a process in which the reactant gases are pyrolyzed and deposited on the surface of a hot wire to form SiC. After the SiC deposition process is completed, the resulting continuous SiC fibers are densely wound onto a take-up wheel. Multiple layers of densely packed SiC fibers must be wound around the take-up wheel to ensure fiber continuity. To prevent the SiC fibers from different layers from mixing, sulfuric acid paper tape is manually laid between each layer. This manual operation significantly increases labor costs, making it unsuitable for mass production and resulting in low production efficiency. It also increases the safety risks for operators in hazardous environments.

[0004] Patent publication number CN220744731U proposes an automatic paper padding device for cable winding. This device is used for paper padding during the optical cable winding process. The paper tape is laid synchronously with the cable winding, and the tape is wound and overlapped at the bottom of the cable to isolate and protect the upper and lower layers of the cable. However, this device focuses on the winding of the optical cable and does not involve the automatic laying of sulfate paper tape on the winding wheel to isolate the SiC fiber layer. Therefore, it cannot meet the requirement for isolation between different layers of SiC fiber during the winding process.

[0005] Patent publication number CN108327316A proposes a small, integrated continuous fiber winding / layout device, primarily for the processing of small concave rotating parts. It achieves integrated fiber winding and placement, and controls tension, temperature, and compaction. However, the device primarily focuses on fiber winding, forming, and placement, and fails to address the function and structure of automatically laying sulfuric acid paper tape on the take-up wheel to isolate fiber layers. The device also lacks a tape laying and cutting module, and thus cannot address the interlayer isolation issue associated with multi-layer fiber winding.

[0006] Patent publication number CN111058187A proposes a method and apparatus for preparing SiC fiber prepreg tapes with an attached interface layer. The method focuses on the fiber prepreg preparation process and equipment, including fiber desizing, sizing, and yarn spreading, to improve the prepreg's performance and quality. The equipment is primarily used for interfacial layer deposition and resin coating of SiC fiber prepreg tapes and does not involve the automated placement of sulfuric acid paper tape on a take-up roll to isolate the fiber layer.

[0031] The design idea of the present invention is:

[0032] Prior art relied on manually laying sulfuric acid paper tape to isolate the layers of SiC fiber during multi-layer winding. This resulted in low efficiency, high costs, and safety risks. While existing automated laying mechanisms involved tension control and paper tape transport, they were not designed to address the specific requirements of SiC fiber production, such as high temperatures and densely packed multi-layer winding.

[0033] Building on existing SiC fiber production technology, this invention innovatively improves and expands the paper tape laying process during the winding process. By utilizing a cam cutting mechanism and tension control, a cutting servo motor drives the cam, which automatically cuts the paper tape using a first and second transmission rods and spring shears. Compared to existing cutting mechanisms, this cutting mechanism utilizes a ceramic bearing rolling mechanism to reduce friction, improving durability and precision. Furthermore, the combination with the spring shears is more suitable for rapid cutting during the fiber winding process.

[0034] The present invention limits the tension range of the tension controller to 1.0×10 -3 N·m~4.0×10 -3 N·m, and the precise adjustment of the paper tape tension is achieved through the connection between the second driven wheel and the tension controller. This parameter directly affects the stability of paper tape laying and the quality of fiber winding.

[0035] The present invention achieves precise matching of the winding wheel speed (10-20 rpm), the winding wheel speed (1-10 rpm), and the paper tape feed speed by linking the winding servo motor, the winding servo motor, and the transmission servo motor. This coordinated control mechanism is not used in existing technologies and cannot meet the interlayer isolation requirements of densely packed SiC fiber winding.

[0036] The present invention realizes precise matching of the speed of the wire-receiving wheel (10rpm~20rpm), the speed of the wire-receiving wheel (1rpm~10rpm) and the paper tape conveying speed through the linkage of the wire-receiving servo motor, the wire-receiving servo motor and the transmission servo motor, thereby meeting the interlayer isolation requirements of the multi-layer dense winding of SiC fibers.

[0037] The present invention has the following advantages and beneficial effects:

[0038] 1. The present invention realizes the automatic operation of laying sulfuric acid paper tape, greatly reduces labor costs, can realize batch operation, greatly improves production efficiency, reduces the operation of operators in dangerous environments, and reduces safety risks.

[0039] 2. This invention achieves automated laying of sulfuric acid paper tape during the multi-layer winding process of SiC fibers through the coordinated design of a cam cutting mechanism and a tension-controlled laying mechanism. A cutting servo motor drives the cam, which, through the leverage of first and second transmission rods, drives spring scissors to cut the paper tape. A ceramic bearing rolling mechanism is installed at the end of the transmission rod that contacts the cam, reducing friction loss and making it suitable for high-temperature environments.

[0040] 3. The second driven wheel of this invention is connected to a tension controller, ensuring the stability of paper tape conveyance by adjusting the tension range. This ensures the stability of paper tape laying and improves the quality of fiber winding. The spacing between the driving wheel and the first driven wheel is adjustable, compacting the paper tape to prevent deviation. Through tension control and precise cutting, the paper tape is prevented from deflection or breakage, ensuring the consistency of interlayer isolation, and improving the yield rate of SiC fiber composite materials.

[0041] 4. The linkage of the wire-collecting servo motor, the wire-arranging servo motor and the transmission servo motor of the present invention realizes the precise matching of the speed of the wire-collecting wheel, the speed of the wire-arranging wheel and the speed of the paper tape conveying, ensuring the accurate laying of the paper tape after each layer of fiber is wound.

[0042] 5. The present invention utilizes a cutting servo motor to drive a cam, links spring scissors through the lever principle, and combines a ceramic bearing rolling device to reduce friction. The combination of the cam cutting mechanism and the ceramic bearing rolling device solves the durability problem in high temperature environments. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0049] like Figure 1-Figure 5 As shown, a device for automatically laying a sulfuric acid paper tape on a receiving wheel includes a base 1, a winding mechanism 2, a cutting mechanism 3, a laying mechanism 4, and a controller 5. The winding mechanism 2 and the laying mechanism 4 correspond to each other and are arranged on the base 1. The sulfuric acid paper tape is wound around the second driven wheel 44 of the laying mechanism 4, and one end of the sulfuric acid paper tape extends between the first driven wheel 43 and the transmission wheel 42. The cutting mechanism 3 is arranged on one side of the upper part of the laying mechanism 4 and above the winding mechanism 2. The sulfuric acid paper tape support platform 45 of the laying mechanism 4 corresponds to the spring scissors 36 of the cutting mechanism 3, and the lower part of the spring scissors 36 corresponds to the receiving wheel 22 of the winding mechanism 2. SiC fiber 24 is wound around the wire arrangement wheel 23 of the winding mechanism 2, and one end of the SiC fiber 24 is connected to the receiving wheel 22 of the winding mechanism 2. The input end of the controller 5 is connected to the tension controller 47 on the laying mechanism 4, and the output end of the controller 5 is respectively connected to the wire receiving servo motor and the wire arrangement servo motor of the winding mechanism 2, the cutting servo motor 31 of the cutting mechanism 3, and the transmission servo motor 41 of the laying mechanism 4.

[0050] like Figure 1 As shown, the four corners of the base 1 are provided with footings 11, each of which is mounted to the bottom of the base 1 via an anchor bolt 13. This ensures the stability of the device during operation and prevents displacement due to vibration or external forces. Handles 12 are provided on the top and sides of the base 1, which are connected to the base 1 via screws, making it easier for operators to carry the device and improving operability and convenience.

[0051] like Figure 4As shown, the winding mechanism 2 includes a housing 21, a wire-receiving servo motor, a wire-discharging servo motor, a wire-receiving wheel 22, and a wire-discharging wheel 23. The housing 21 serves as the main frame of the winding mechanism 2, and its bottom is connected to the upper surface of the base 1 by bolts or other fixing means, thereby firmly mounting the winding mechanism 2 on the base 1. A wire-receiving servo motor and a wire-discharging servo motor are housed within the housing 21. The output shaft of the wire-receiving servo motor is connected to the wire-receiving wheel 22, and the output shaft of the wire-discharging servo motor is connected to the wire-discharging wheel 23. SiC fiber 24 is wound around the wire-discharging wheel 23. When the wire-receiving servo motor and the wire-discharging servo motor are started, they can drive the wire-receiving wheel 22 and the wire-discharging wheel 23 to rotate accordingly, thereby achieving the wire-receiving and wire-discharging operations of the SiC fiber 24.

[0052] like Figure 2 As shown, the cutting mechanism 3 includes a cutting servo motor 31, a cam 32, a first transmission rod 33, a first transmission rod bracket 34, a second transmission rod 35, and a spring scissors 36, wherein: the output shaft of the cutting servo motor 31 is mounted with the cam 32. When the cutting servo motor 31 is running, it can drive the cam 32 to rotate. One end of the first transmission rod 33 is in sliding contact with the cam 32, and a rolling device consisting of the first transmission rod 33, a pin 38, and a rolling bearing 37 (preferably a ceramic bearing) is provided at the end in contact with the cam 32. The pin 38 is inserted into the opening at one end of the first transmission rod 33. The rolling bearing is mounted on the pin 38 at the opening and contacts the cam 32 through the rolling bearing 37 to reduce friction and improve the operating efficiency and service life of the mechanism. The opening at the other end of the first transmission rod 33 is connected to the top of the second transmission rod 35 by a pin. The bottom end of the second transmission rod 35 is connected to the handle of the spring scissors 36. The bottom of the spring scissors 36 corresponds to the wire collecting wheel 22. In addition, the middle position of the first transmission rod 33 is connected to the first transmission rod bracket 34 via a pin, allowing the first transmission rod 33 to swing around the pin. In this way, when the cam 32 rotates, the transmission action of the first transmission rod 33 and the second transmission rod 35 can drive the spring scissors 36 to cut the sulfuric acid paper tape.

[0053] like Figure 3 、 Figure 5As shown, the laying mechanism 4 includes a transmission servo motor 41, a transmission wheel 42, a first driven wheel 43, a second driven wheel 44, a sulfuric acid paper tape support platform 45, and a bracket 46. The bracket 46 serves as the supporting structure of the laying mechanism 4, and its bottom is fixedly connected to the base 1 by bolts or other means. The transmission servo motor 41 is fixed to the bracket 46 by bolts, and the transmission wheel 42 is connected to the central axis of the transmission servo motor 41. When the transmission servo motor 41 is in operation, it can drive the transmission wheel 42 to rotate. A first driven wheel 43 is provided above the transmission wheel 42 and corresponds to the first driven wheel 43. The first driven wheel 43 is fixed to the lower opening of the Y-shaped fixing bracket 433 on the upper portion of the bracket 46. The lower opening of the Y-shaped fixing bracket 433 is penetrated by a pin 434. The first driven wheel 43 is connected to the pin 434 via a ceramic bearing 435. The upper end of the Y-shaped fixing bracket 433 extends into the U-shaped groove on the side of the U-shaped block 432 and is connected to the U-shaped block 432 via a pin. The U-shaped block 432 is fixed to the bracket 46 via a fixing pin 431. This connection method allows the first driven wheel 43 to rotate flexibly while ensuring its stability during operation. A tension controller 47 is installed at the lower portion of the bracket 46 and is located below the transmission wheel 42. The second driven wheel 44 is mounted to the output end of the tension controller 47 via a central axis. The second driven wheel 44 is connected to the tension controller 47 to adjust the tension of the sulfuric acid paper tape during transportation. The sulfuric acid paper tape support platform 45 is installed on the side of the transmission wheel 42 and the first driven wheel 43 on the upper part of the bracket 46. The sulfuric acid paper tape support platform 45 corresponds to the spring scissors 36 of the cutting mechanism 3, providing support for the sulfuric acid paper tape during the transportation process, ensuring that the paper tape can be smoothly transported to the collecting wheel.

[0054] When the device is running, the transmission servo motor 41 drives the transmission wheel 42 to rotate, and the transmission wheel 42 cooperates with the first driven wheel 43 to clamp and pull the sulfuric acid paper tape wrapped around the second driven wheel 44. In the process of the paper tape being pulled forward, due to the friction between the paper tape and the surface of the second driven wheel 44, under the action of the friction, the second driven wheel 44 will passively rotate as the paper tape moves, thereby achieving the guiding and conveying functions of the paper tape. The tension controller 47 can monitor and adjust the tension of the paper tape in real time, ensuring that the second driven wheel 44 cooperates with the conveying process of the paper tape at an appropriate speed and tension, ensuring that the paper tape maintains a stable tension during the conveying process, avoiding slack or excessive tension, thereby achieving a smooth laying of the sulfuric acid paper tape on the winding wheel.

[0055] In the present invention, the controller 5 can be composed of a housing, a power supply, a control screen, and a programmable control module (PLC). The connections and functions of these components are as follows: The housing houses the power supply, programmable control module, and control screen, providing electromagnetic shielding and heat dissipation. The housing is made of aluminum alloy. The power supply is connected to the programmable control module and control screen via wires, supplying power to them. The input of the programmable control module is connected to a tension controller, while the output of the programmable control module is connected to the control screen and servo motors (the wire collection servo motor and the wire arrangement servo motor of the winding mechanism 2, the cutting servo motor 31 of the cutting mechanism 3, and the transmission servo motor 41 of the laying mechanism 4). The programmable control module, connected to the wire collection servo motor and the wire arrangement servo motor of the winding mechanism 2, controls the rotation speed of the wire collection wheel 22 and the lateral movement of the wire arrangement wheel 23, ensuring dense fiber winding. The programmable control module, connected to the cutting servo motor 31 of the cutting mechanism 3, controls the cutting servo motor 31 to achieve automatic cutting. The programmable control module, connected to the tension controller 47 and drive servo motor 41 of the laying mechanism 4, adjusts the paper tape feed speed and tension to ensure synchronous compaction of the paper tape and fiber. The controller 5 first activates the winding mechanism 2 to collect the wire, then activates the laying mechanism 4 to release the paper tape, and finally triggers the cutting mechanism 3. The control screen controls parameters such as the wire collection speed, line arrangement speed, and tension, achieving adaptive production.
