Description

Technical Field

[0001] This invention belongs to the field of inorganic fiber fabric winding equipment, specifically an inorganic fiber fabric winding machine with a novel tension adjustment mechanism. Background Technology

[0002] Copper-clad laminates (CCLs) are a core component of electronic technology. With technological advancements, circuit board manufacturing is moving towards higher precision, higher density, higher layering, higher integration, and thinner designs. A fundamental component of CCLs is inorganic fiber cloth, such as electronic cloth and quartz cloth. Taking electronic cloth as an example, electronic cloth refers to the general term for electronic-grade glass fiber cloth used in the electronics industry. Its main specifications include 7628, 2313, 2116, 1080, 106, 1010, and 1000. The thickest cloth is 220 g / m² (0.18 mm), and the thinnest is 10 g / m² (0.015 mm). Electronic cloth is woven on air-jet looms, and the woven cloth is then wound up using a specialized "cloth winding machine" to form rolls for easy transportation and subsequent processing. The winding process faces the following challenges: When winding up inorganic fiber cloth, it is necessary to ensure that there is appropriate tension on the fiber cloth to guarantee the winding quality. However, during the winding process, due to the differences and changes in the unloading speed of the subsequent weaving equipment, there will be uneven tension distribution, resulting in poor winding quality.

[0003] Furthermore, due to the characteristics of inorganic fiber cloth, the "tight inside and loose outside" requirement needs to be met during the winding process to ensure that the final fiber cloth roll will not form wrinkles inside and to prevent the fiber cloth roll from being too tight on the outside and breaking. Therefore, the tension on the fiber cloth needs to be gradually reduced during the winding process.

[0004] Chinese patent CN210418570U discloses a tension control device for a glass fiber fabric winding machine. The device includes a winding roller for winding fabric into a roll, a pressure roller for close contact with the roll, and a tension controller for adjusting the rotational speed of the pressure roller. This design ensures that the pressure roller remains in contact with the roll, and the tension controller controls the roller's rotational speed, creating relative friction between the fabric and the pressure roller. This guarantees consistent tension across different roll positions, resulting in more stable winding and reducing the likelihood of roll misalignment or loosening.

[0005] However, the aforementioned patents still have the following drawbacks: 1. The above-mentioned patent uses a counterweight to apply tension to the fiber cloth. When it is not possible to apply the corresponding tension to different types of fabrics, the tension cannot be automatically adjusted. Operators usually need to manually adjust the weight of the counterweight, which wastes time and manpower and affects production efficiency.

[0006] 2. Furthermore, the patent uses a counterweight to apply tension, which has poor tension adjustment accuracy and makes it difficult to apply precise and delicate tension to inorganic fiber cloth, affecting the winding quality. At the same time, the tension can only be adjusted when the machine is stopped, and it cannot be adjusted in real time during operation, resulting in poor flexibility of the winding device and not conforming to the development trend of automated control.

[0007] 3. When the above-mentioned patent uses a counterweight to apply tension, there is a speed difference between the winding speed and the unwinding speed. As a result, the fiber cloth is prone to cause the compensation roller to float up and down during winding. During this process, the weight of the counterweight, the gravitational acceleration when the counterweight moves, and the friction between its moving parts will all affect the tension applied to the fiber cloth, resulting in uneven tension distribution on the fiber cloth roll.

[0008] 4. The tension adjustment method of the above patent is relatively rigid and it is difficult to automatically adjust the winding action and the applied tension according to the winding requirements of "tight inside and loose outside", which is not conducive to improving the winding quality. Summary of the Invention

[0009] To overcome the shortcomings of existing technologies, this invention addresses the technical problem that, compared to the traditional method of applying tension using a counterweight, the tension generated by the first cylinder can automatically and conveniently adjust the tension according to the different winding requirements of inorganic fiber fabrics of different materials. Furthermore, the tension control is more precise and stable, and it can achieve stable application of even small tension values. A first potentiometer identifies the torsion signal, thereby providing feedback to adjust the winding speed of the winding roller, compensating for and adapting to the unloading speed of the subsequent weaving equipment, ensuring winding quality, and preventing the fiber fabric from being wrapped too tightly or too loosely on the winding roller. Simultaneously, a pressure-adjusting valve compensates for and adjusts the first cylinder, ensuring a constant applied tension and thus guaranteeing winding quality. An adjustable balance bar is used to balance the weight of the tension roller; during the up-and-down deflection of the tension roller, the balance bar counteracts the weight of the tension roller. The influence of gravitational acceleration during deflection on tension is considered. The low-friction bearing and the low-resistance cylinder design of the first cylinder reduce the impact of friction on tension, ensuring uniform tension. The signal received by the second potentiometer is used to control the tension of the second cylinder via a pressure-adjusting compensation valve, which in turn controls the damping of the magnetic powder clutch. This achieves the effect of gradually reducing the radial pressure applied by the pressure roller to the fiber roll and the tension applied by the magnetic powder clutch to the fiber roll itself during the winding process. This stably meets the "tight inside, loose outside" winding requirement of the fiber roll, ensuring winding quality. The winding and tension adjustment processes are automatic, requiring no external human intervention. While improving winding efficiency, it maintains the stability and consistency of winding quality. Furthermore, the tension change is a continuous linear change with a smooth transition, resulting in a more uniform tension distribution throughout the roll, effectively improving winding quality.

[0010] To achieve the above objectives, the present invention provides the following technical solution: an inorganic fiber fabric winding machine with a novel tension adjustment mechanism, comprising: The frame has two guide rollers rotatably connected to its top. Inside the frame, below the guide rollers, a first tension adjusting component and a second tension adjusting component are arranged in sequence. A winding component is arranged at the bottom of the frame. The first tension adjustment component includes a first rotating shaft, which is rotatably connected to the frame. Two rocker arms are fixedly connected to the first rotating shaft, and a tension roller is rotatably connected between the ends of the two rocker arms. Connecting rods are fixedly connected to both ends of the first rotating shaft that extend into the frame. First cylinders are hinged at both ends of the frame at the corresponding positions of the two connecting rods. The extended end of each first cylinder is hinged to the corresponding connecting rod.

[0011] Furthermore, each of the swing arms has an adjustment groove at the end away from the tension roller, and a balance bar is provided between the two ends of the two swing arms away from the tension roller. The balance bar can be adjusted within the range of the adjustment groove, and the balance bar is fixed at a specific position in the adjustment groove by bolts.

[0012] Furthermore, the frame is equipped with multiple pressure regulating and compensating valves, and each of the first cylinders is connected to the corresponding pressure regulating and compensating valve through an air guide pipe. A first bracket is provided at the corresponding position at the end of the first rotating shaft in the frame. A first potentiometer is fixedly connected to the first bracket. A first gear is fixedly connected to the signal input end of the first potentiometer. A first half gear that meshes and drives with the first gear is fixedly connected to the end of the first rotating shaft.

[0013] Furthermore, low-friction bearings are respectively provided at the rotatable connection between the first rotating shaft and the frame and at the rotatable connection between the swing arm and the tension roller, and the first cylinder is a low-resistance cylinder.

[0014] Furthermore, the second tension adjustment component includes a second rotating shaft rotatably disposed within the frame, two swing arms fixedly connected to the second rotating shaft, a pressure roller for applying radial pressure to the fiber cloth roll rotatably connected between the ends of the two swing arms, an auxiliary roller rotatably disposed between the two swing arms near the pressure roller, and a second cylinder hinged to the frame at a corresponding position of each swing arm, the extended end of each second cylinder being hinged to the corresponding swing arm.

[0015] Furthermore, a second half gear is fixedly connected to one end of the second rotating shaft that extends into the frame. A second bracket is provided in the frame at the position corresponding to the second half gear. A second potentiometer is fixedly connected to the second bracket. The signal input end of the second potentiometer is fixedly connected to a second gear that meshes and drives with the second half gear. Each second cylinder is connected to the corresponding pressure regulating and compensating valve through an air guide pipe.

[0016] Furthermore, the winding component includes a winding roller for winding inorganic fiber cloth. A first rotary cylinder and a second rotary cylinder are respectively arranged at both ends of the winding roller in the frame. The working ends of the first rotary cylinder and the second rotary cylinder are respectively provided with chucks. The center of both ends of the winding roller is provided with an internal toothed ring that can engage with the chucks.

[0017] Furthermore, a motor is fixedly connected inside the frame to one side of the first rotary cylinder, and a drive sprocket is fixedly connected to the power output end of the motor. A driven sprocket is drivenly connected to the end of the first rotary cylinder away from the take-up roller, and a chain is drivenly connected between the driven sprocket and the drive sprocket.

[0018] Furthermore, brackets are fixedly connected to the bottom of both ends of the take-up roller within the frame, and a set of rollers is rotatably connected to each bracket, with each set of rollers making rolling contact with the end of the take-up roller.

[0019] Furthermore, a footboard is provided on the side of the frame away from the winding component to facilitate personnel passage, and the two ends of the footboard are rotatably equipped with deflecting rollers for guiding the fiber cloth through the footboard.

[0020] In summary, compared with the prior art, the beneficial effects of the present invention are as follows: (1) Compared with the traditional method of applying tension by using a counterweight, the tension generated by the first cylinder can automatically and conveniently adjust the tension according to the different winding requirements of inorganic fiber cloth of different materials, and the tension control is more precise and stable, and can achieve stable application of a smaller tension value.

[0021] (2) The first potentiometer identifies the torsion signal, thereby feeding back and adjusting the winding speed of the winding roller to compensate for and adapt to the unloading speed of the rear weaving equipment, ensuring the winding quality and preventing the fiber cloth on the winding roller from being wrapped too tightly or too loosely. At the same time, the first cylinder is compensated and adjusted by the pressure adjustment compensation valve to ensure that the applied tension is constant and to ensure the winding quality.

[0022] (3) By setting an adjustable balance bar to balance the weight of the tension roller, the balance bar can be used to counteract the influence of the tension roller's weight and the gravitational acceleration during the deflection on the tension during the up-down deflection process. The low-friction bearing and the first cylinder are set with low-resistance cylinders to reduce the influence of friction on the tension and ensure uniform tension.

[0023] (4) By using the signal received by the second potentiometer, the tension of the second cylinder is controlled by the pressure adjustment compensation valve and the damping magnitude of the magnetic powder clutch is changed, so as to achieve the effect of the radial pressure applied by the pressure roller to the fiber cloth roll and the tension applied by the magnetic powder clutch to the fiber cloth itself gradually decreasing as the winding process proceeds, so as to stably meet the winding requirements of "tight inside and loose outside" of the fiber cloth roll and ensure the winding quality.

[0024] (5) The winding and tension adjustment process is automatic and does not require external human intervention. It improves winding efficiency while maintaining the stability and consistency of winding quality. Furthermore, the tension change is a continuous linear change with a smooth transition. The tension distribution on the roll is more uniform, which effectively improves the winding quality. Attached Figure Description

Detailed Implementation

[0036] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0037] Example 1: like Figure 1-10 As shown, an inorganic fiber fabric winding machine with a novel tension adjustment mechanism includes a frame 10. A winding roller 32 is rotatably mounted at the bottom of the frame 10. Internal toothed rings 36 are fixedly connected to the center of each end of the winding roller 32. A first rotary cylinder 33 and a second rotary cylinder 34 capable of extension, retraction, and rotation are respectively mounted at the ends of the winding roller 32 inside the frame 10. The ends of the first rotary cylinder 33 and the second rotary cylinder 34 are respectively provided with clamps 35 capable of engaging with the internal toothed rings 36. A motor 40 is fixedly connected to one side of the first rotary cylinder 33 inside the frame 10. A drive sprocket 38 is fixedly connected to the power output end of the motor 40. A driven sprocket 37 is drivenly connected to the end of the first rotary cylinder 33 away from the winding roller 32. A chain 39 is drivenly connected between the driven sprocket 37 and the drive sprocket 38.

[0038] The inorganic fiber fabric is wound up by setting the winding roller 32 to rotate, which facilitates the subsequent transportation and processing of the fiber fabric. The winding action can be realized and the winding roller 32 can be loaded and unloaded by controlling the rotation and opening and closing of the first rotary cylinder 33 and the second rotary cylinder 34.

[0039] like Figure 1-10 As shown, brackets 41 are fixedly connected to the bottom of both ends of the take-up roller 32 inside the frame 10. A set of rollers 42 are rotatably connected to each bracket 41, and each set of rollers 42 makes rolling contact with the end of the take-up roller 32.

[0040] By setting the support roller 42, the weight of the fiber cloth borne by the second rotary cylinder 34 and the chuck 35 can be shared, avoiding the huge weight of the fiber cloth wound on the take-up roller 32 from putting pressure on the second rotary cylinder 34 and the chuck 35, which would cause the second rotary cylinder 34 and the chuck 35 to bend and be damaged.

[0041] As shown in Figure 10, two guide rollers 11 are rotatably connected to the top of the frame 10. A first rotating shaft 12 is rotatably connected to the frame 10 below the two guide rollers 11. Two swing rods 13 are symmetrically distributed and fixedly connected to the first rotating shaft 12. A tension roller 14 is rotatably connected between the ends of the two swing rods 13. Connecting rods 17 are fixedly connected to both ends of the first rotating shaft 12 that extend into the frame 10. A first cylinder 18 is hinged to the corresponding position at the end of the first rotating shaft 12 inside the frame 10. The extended end of each first cylinder 18 is hinged to the end of the connecting rod 17 away from the first rotating shaft 12.

[0042] By setting the first cylinder 18 to generate a downward force, the first rotating shaft 12 is twisted, and the pendulum 13 presses down on the fiber cloth, applying tension to the fiber cloth. Compared with the traditional tension application method using a counterweight, the tension applied by this solution is adjustable and the tension adjustment is stepless, which can apply more precise and stable tension to the fiber cloth.

[0043] Meanwhile, this solution allows for tension adjustment by regulating gas pressure. Compared to the traditional method of applying tension using a counterweight, it eliminates the need for operators to repeatedly add or remove the weight of the counterweight, resulting in a high degree of automation and a more convenient and efficient tension adjustment method, thereby liberating productivity and improving production efficiency.

[0044] like Figure 1-10 As shown, multiple pressure regulating and compensating valves 44 are provided inside the frame 10. Each first cylinder 18 is connected to the corresponding pressure regulating and compensating valve 44 through an air guide pipe. A first bracket 19 is provided inside the frame 10 at the corresponding position at the end of the first rotating shaft 12. A first potentiometer 20 is fixedly connected to the first bracket 19. A first gear 21 is fixedly connected to the signal input end of the first potentiometer 20. A first half gear 22 that meshes and drives with the first gear 21 is fixedly connected to the end of the first rotating shaft 12.

[0045] By setting the first potentiometer 20, the first gear 21, and the first half gear 22, when the winding speed of the inorganic fiber fabric is too fast or too slow compared to the unloading speed of the subsequent weaving equipment, the fabric tightens or loosens between the two guide rollers 11. This causes the swing arm 13 and the tension roller 14 to deflect upward under the pull of the fiber fabric, or to deflect downward under the pulling force of the first cylinder 18. This causes the first rotating shaft 12 to twist, and the first potentiometer 20 identifies the twist signal, thereby providing feedback to adjust the winding speed of the winding roller 32, compensating for and adapting to the unloading speed of the subsequent weaving equipment, so that the swing arm 13 and the tension roller 14 return to the correct position, ensuring the winding quality and preventing the fiber fabric on the winding roller 32 from being wrapped too tightly or too loosely.

[0046] During the up-and-down deflection of the tension roller 14, the connecting rod 17 synchronously pulls the first cylinder 18 to extend and retract. At this time, the first potentiometer 20 detects the signal and feeds it back to the control system. The pressure and volume of air in the first cylinder 18 can be compensated and adjusted by the pressure adjustment compensation valve 44, so that even if the swing rod 13 and the tension roller 14 are deflecting, the tension applied to the fiber cloth by the first cylinder 18 remains constant, thereby ensuring the winding quality.

[0047] like Figure 1-10 As shown, each swing arm 13 has an adjustment groove 15 at one end away from the tension roller 14, and a balance bar 16 is provided between the two ends of the two swing arms 13 away from the tension roller 14. The balance bar 16 can be adjusted within the range of the adjustment groove 15. The balance bar 16 is fixed at a specific position in the adjustment groove 15 by bolts. The first cylinder 18 is preferably a low-resistance cylinder. Low-friction bearings are provided at the rotatable connection between the frame 10 and the first rotating shaft 12 and at the rotatable connection between the swing arm 13 and the tension roller 14.

[0048] By setting an adjustable balance bar 16 to balance the weight of the tension roller 14, the balance bar 16 counteracts the influence of the tension roller 14's own weight and the gravitational acceleration during deflection on the tension during the up-and-down deflection process. At the same time, the low-friction bearing and the first cylinder 18 are set as low-resistance cylinders to further reduce the influence of friction between various action structures on the tension, thus keeping the tension applied to the fiber cloth stable at all times. This makes the tension distribution of the fiber cloth more uniform after winding, thereby improving the winding quality.

[0049] like Figure 1-10As shown, a second rotating shaft 27 is rotatably arranged below the first rotating shaft 12 inside the frame 10. Two swing arms 23 are fixedly connected to the second rotating shaft 27. A pressure roller 25 for applying radial pressure to the fiber cloth roll is rotatably connected between the ends of the two swing arms 23. An auxiliary roller 24 is rotatably arranged between the two swing arms 23 near the pressure roller 25. A second cylinder 43 is hinged to the frame 10 at the corresponding position of each swing arm 23. The extended end of each second cylinder 43 is hinged to the corresponding swing arm 23. A second half gear 28 is fixedly connected to one end of the second rotating shaft 27 that extends into the frame 10. A second bracket 29 is arranged inside the frame 10 at the corresponding position of the second half gear 28. A second potentiometer 30 is fixedly connected to the second bracket 29. A second gear 31 that meshes and drives with the second half gear 28 is fixedly connected to the signal input end of the second potentiometer 30. Each second cylinder 43 is connected to the corresponding pressure regulating and compensating valve 44 through an air guide pipe.

[0050] By setting up the swing arm 23 and the pressure roller 25, the second cylinder 43 generates a pulling force, which applies radial pressure to the fiber cloth wound on the take-up roller 32 through the pressure roller 25. At the same time, by controlling the magnetic powder clutch 26, the pressure roller 25 generates rotational damping, thereby applying a second stage of tension to the fiber cloth through the static friction between the pressure roller 25 and the fiber cloth.

[0051] As the amount of fiber cloth wound on the take-up roller 32 gradually increases, the diameter of the fiber cloth roll on the take-up roller 32 also increases. The pressure roller 25 always presses against the outermost side of the fiber cloth roll. Therefore, the second cylinder 43 needs to extend outward synchronously and the swing arm 23 needs to deflect synchronously. The deflection angle of the swing arm 23 is detected by the second potentiometer 30, and the pressure regulating valve 44 is synchronously controlled to compensate and adjust the air pressure and air volume into the second cylinder 43, so that the radial pressure applied by the pressure roller 25 to the fiber cloth roll is always stable.

[0052] Meanwhile, due to the inherent characteristics of inorganic fiber cloth, the winding process needs to meet the requirement of "tight inside and loose outside" to ensure that the final fiber cloth roll will not form wrinkles inside and to prevent the fiber cloth roll from being too tight on the outside and breaking. Therefore, the tension on the fiber cloth needs to be gradually reduced during the winding process. However, the tension applied to the fiber cloth by the tension roller 14 remains constant. Therefore, the second stage of tension applied to the fiber cloth by the pressure roller 25 is needed to gradually reduce the tension. This can be achieved by controlling the pulling force of the second cylinder 43 through the pressure regulating compensation valve 44 and controlling the damping magnitude of the magnetic powder clutch 26 through the signal received by the second potentiometer 30. This achieves the effect of gradually reducing the radial pressure applied to the fiber cloth roll by the pressure roller 25 and the tension applied to the fiber cloth itself by the magnetic powder clutch 26 as the winding process progresses, thus ensuring the winding quality.

[0053] Furthermore, this process is automated and requires no external human intervention, improving winding efficiency while maintaining the stability and consistency of winding quality. Moreover, this process involves continuous linear changes, resulting in a smooth tension transition and a more uniform tension distribution throughout the fabric roll, effectively improving winding quality.

[0054] like Figure 1-10 As shown, a footboard frame 45 is provided on the side of the frame 10 away from the winding component to facilitate personnel passage. The two ends of the footboard frame 45 are rotatably equipped with deflecting rollers 46 for guiding the fiber cloth through the footboard frame 45.

[0055] By setting up the pedal frame 45 and the reversing roller 46, the fiber cloth is fed out from the rear weaving equipment and first passes through the pedal frame 45 and the reversing roller 46 before entering the main body of this device. This leaves a passage large enough for personnel to pass through between this device and the rear weaving equipment, making it convenient for personnel to install and adjust the fiber cloth.

[0056] In this embodiment, initially, the device is connected to the power supply and control system. At this time, the take-up roller 32 has not yet been installed, and the first rotary cylinder 33 and the second rotary cylinder 34 are in the retracted state. The operator adjusts the position of the balance bar 16 so that the balance bar 16, the swing bar 13, and the tension roller 14 form a lever structure with the first rotating shaft 12 as the fulcrum, so that the balance bar 16 counteracts the weight of the tension roller 14. When the take-up operation is required, the operator first places the take-up roller 32 on the two sets of support rollers 42. Then, the operator controls the first rotary cylinder 33 and the second rotary cylinder 34 to extend outward, so that the chuck 35 and the internal toothed ring 36 are engaged and bitten, thus completing the installation of the take-up roller 32.

[0057] The operator then first wraps the fiber cloth around the footplate frame 45 and the deflector roller 46, then around the guide roller 11 and the tension roller 14 in sequence, and then around the auxiliary roller 24 and the pressure roller 25, finally winding and fixing it onto the surface of the take-up roller 32. The final state of the fiber cloth is shown in the attached figure. Figure 5 As shown. The second cylinder 43 is controlled to make the pressure roller 25 press against the outer diameter of the fiber cloth roll on the take-up roller 32, and the swing arm 13 is controlled to be in a horizontal position. The rear weaving equipment gradually feeds the material, and the motor 40 is started to drive the first rotary cylinder 33 to drive the take-up roller 32 to rotate, so that the take-up action is carried out synchronously with the feeding action of the weaving equipment.

[0058] During the winding process, the first cylinder 18 generates a downward force according to the set value, which in turn causes the tension roller 14 to press down on the fiber cloth through the connecting rod 17, the first rotating shaft 12 and the swing rod 13 to apply tension. Compared with the traditional method of applying tension by using a counterweight, the tension generated by the first cylinder 18 can automatically and conveniently adjust the tension according to the different winding requirements of inorganic fiber cloth of different materials, and the tension control is more precise and stable, and can achieve stable application of a smaller tension value.

[0059] Since the feeding speed of the weaving equipment may vary, it is necessary to control the winding speed to match the feeding speed to avoid changes in tension caused by the loosening or tightening of the fiber cloth. When the feeding speed is slower than the winding speed, the fiber cloth tends to tighten, which will cause the tension roller 14 to deflect upward, thereby driving the first rotating shaft 12 to rotate and driving the first half gear 22 to rotate. The deflection signal is input to the first potentiometer 20 through the meshing transmission of the first gear 21 and the first half gear 22. The first potentiometer 20 feeds back the collected signal to the control system, and the control system automatically controls the motor 40 to slow down the winding speed, so the fiber cloth loosens again, and the swing arm 13 and the tension roller 14 reset. When the feeding speed is faster than the winding speed, the process is reversed, which will not be described in detail here.

[0060] During the adjustment of the winding speed, the adjustment process itself is a real-time dynamic adjustment. The swing arm 13 and the tension roller 14 only swing back and forth within a small range during the entire winding process. During the swing, the balance bar 16 can offset the influence of the tension roller 14's own weight and gravitational acceleration on the tension magnitude. The low-friction bearing and the first cylinder 18 are set with low-resistance cylinders to further reduce the influence of friction on the tension.

[0061] As the swing arm 13 and tension roller 14 swing, the extension and retraction of the first cylinder 18 changes accordingly. The control system, based on the deflection signal received by the first potentiometer 20, controls the pressure adjustment compensation valve 44 to supplement or reduce the air volume in the first cylinder 18, and ensures that the pressure of the first cylinder 18 remains constant during the change of extension and retraction. This ensures that even during the deflection of the tension roller 14, the tension applied to the fiber cloth by the first cylinder 18 remains constant, thereby ensuring the winding quality.

[0062] Meanwhile, as the amount of fiber cloth wound on the take-up roller 32 increases, the diameter of the fiber cloth roll gradually increases. The second cylinder 43 generates tension, which applies radial pressure to the fiber cloth wound on the take-up roller 32 through the pressure roller 25. At the same time, the magnetic powder clutch 26 is controlled to make the pressure roller 25 generate rotational damping, thereby applying a second stage of tension to the fiber cloth through the static friction between the pressure roller 25 and the fiber cloth.

[0063] As the diameter of the fiber roll wound on the take-up roller 32 gradually increases, while the pressure roller 25 remains against the outer diameter of the fiber roll, the swing arm 23 will gradually deflect as the take-up operation proceeds. At this time, the second cylinder 43 gradually extends outward, and the second rotating shaft 27 rotates accordingly, driving the second half gear 28 to rotate. The meshing transmission between the second half gear 28 and the second gear 31 enables the second potentiometer 30 to receive the torsion signal and feed the signal back to the control system. The control system replenishes the air volume into the second cylinder 43 by controlling the pressure regulating compensation valve 44 and ensuring that the air pressure in the second cylinder 43 is constant. This controls the second cylinder 43 to maintain a constant downward force while changing the extension and retraction amount, thereby keeping the radial pressure applied by the pressure roller 25 to the fiber roll stable and ensuring the take-up quality.

[0064] After the winding operation is completed, the operator cuts the inorganic fiber cloth and drives the first rotary cylinder 33 and the second rotary cylinder 34 to retract. Then, the winding roller 32 wrapped with the fiber cloth is directly removed, and a new winding roller 32 is replaced to start the winding operation again.

[0065] Example 2: In this embodiment, due to the inherent characteristics of inorganic fiber cloth, the requirement of "tight inside and loose outside" needs to be met during the winding process to ensure that the final fiber cloth roll will not form wrinkles inside and to avoid the fiber cloth roll from being too tight outside and breaking. Therefore, the tension on the fiber cloth needs to be gradually reduced during the winding process. However, the tension applied to the fiber cloth at the tension roller 14 remains constant. Therefore, the second stage of tension applied to the fiber cloth by the pressure roller 25 is needed to gradually reduce the tension.

[0066] As the diameter of the take-up roller 32 increases, the swing arm 23 gradually deflects, causing the second shaft 27 to twist and drive the second half gear 28 to rotate. The meshing transmission between the second half gear 28 and the second gear 31 causes the second potentiometer 30 to receive a torsion signal. The signal received by the second potentiometer 30 controls the pulling force of the second cylinder 43 through the pressure regulating compensation valve 44 and controls the magnetic powder clutch 26 to change the damping magnitude. This achieves the effect of gradually reducing the radial pressure applied by the pressure roller 25 to the fiber cloth roll and the tension applied by the magnetic powder clutch 26 to the fiber cloth itself as the take-up process progresses, thus ensuring the take-up quality.

[0067] The aforementioned first cylinder 18, first potentiometer 20, magnetic powder clutch 26, second potentiometer 30, motor 40, second cylinder 43, pressure regulating compensation valve 44, etc., are mature existing technologies. The structures in the attached drawings are only for illustration and will not be described in detail here.

[0068] The specification and claims use certain terms to refer to specific components. Those skilled in the art will understand that hardware manufacturers may use different names to refer to the same component. This specification and claims do not distinguish components based on differences in name, but rather on differences in function. The term "comprising" throughout the specification and claims is an open-ended term and should be interpreted as "comprising but not limited to." "Approximately" means that within an acceptable margin of error, those skilled in the art can solve the technical problem and substantially achieve the technical effect within a certain margin of error.

[0069] It should be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a product or system comprising a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a product or system. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the product or system that includes said element.
