Description

Technical Field

[0001] This utility model relates to an integrated fiber splitting machine specifically for continuous alumina fibers, belonging to the technical field of textile machinery. Background Technology

[0002] Alumina fiber is a high-performance ceramic fiber, a high-performance inorganic fiber material whose main component is alumina (Al₂O₃), with small amounts of SiO₂, MgO, and other oxides. It features high strength and high modulus; it is resistant to corrosion from molten metals and non-oxide materials, and maintains good chemical stability in oxidizing or reducing atmospheres. It also possesses advantages such as a high melting point, low thermal conductivity, and low coefficient of thermal expansion. Furthermore, it can be used as a high-temperature structural material, a catalyst support for chemical reactions, and a reinforcement in ceramic-based and metal-based composite materials, and is widely used in aerospace, military, automotive, and electromechanical fields.

[0003] The quality of twisting continuous alumina fibers into yarn is one of the important factors affecting fiber products, and the quality of twisting is affected by fiber splitting. Fiber splitting refers to the process of unwinding (releasing) the continuous alumina fibers from the large roll of the product packaging and rewinding them onto a specific take-up die (take-up) before twisting, so as to facilitate the next step of twisting into yarn. Because continuous alumina fibers have high modulus and high strength, they are relatively brittle and prone to breakage when subjected to impact or excessive bending. Therefore, during the fiber splitting process, compared with other fibers, it is more important to strive for a uniform distribution of fibers on the take-up die, avoiding misaligned or disordered layers, to prevent fiber entanglement during twisting and unwinding, which could lead to excessive force and breakage.

[0004] Existing fiber splitting machines cannot achieve good results when splitting continuous alumina fibers, and the equipment structure is complex, with poor practicality of the winding device that works in conjunction with twisting. In addition, traditional fiber splitting machines use two separate devices for unwinding and winding, which takes up a lot of space and is inconvenient to operate. The winding device used for winding also suffers from low control precision, poor stability and high failure rate, which can lead to uneven fiber arrangement. Furthermore, traditional winding devices are driven by chains, and large fiber fluctuations during winding can also affect fiber winding. Utility Model Content

[0005] To address one or more of the aforementioned problems, this utility model provides an integrated fiber splitting machine specifically for continuous alumina fibers, the technical solution of which is as follows.

[0006] This utility model provides an integrated fiber splitting machine for continuous alumina fibers, including a machine base, an automatic fiber feeding device, a tension adjustment device, a first guide wheel, a second guide wheel, a third guide wheel, a fourth guide wheel, continuous alumina fibers, a jacketed fiber guide frame, a winding mold, a base, a first servo motor, a slide table, a second servo motor, and a touch screen human-machine interaction device.

[0007] An automatic unwinding device is used to unwind the continuous alumina fibers from the product packaging onto a large roll; a tension regulating device is used to control the stability of the tension during the fiber splitting process; first, second, third, and fourth guide rollers guide the fibers along a predetermined path for splitting, while simultaneously stabilizing the tension on the fibers; a jacketed fiber guide frame further stabilizes the fibers and evens out the fiber tension; a first servo motor drives the winding die to rotate, winding the fibers onto the winding die at a uniform speed; a second servo motor drives the base to reciprocate on the slide table; the winding die reciprocates while winding, and by adjusting the rotational speed of the first servo motor and the reciprocating transmission distance of the second servo motor, the two servo motors cooperate to adjust the arrangement and tightness of the continuous alumina fibers on the winding die, thereby improving the quality of the wound fibers; a touch-screen human-machine interface device enables precise control of the machine's operation.

[0008] In one embodiment, the rotational speed of the first servo motor is coordinated with the reciprocating speed of the second servo motor, and the ratio of the reciprocating speed of the second servo motor to the rotational speed of the first servo motor is between 1:15 and 1:3. The smaller the ratio, the greater the fiber winding density, which makes the fibers more tightly and evenly arranged during winding, resulting in higher winding quality. The winding of the fibers on the winding die can be adjusted by adjusting the ratio to adapt to the different requirements of the twisting device on the die during twisting operations.

[0009] In one embodiment, the tension adjusting device, in cooperation with the second guide wheel, can detect the fiber tension in real time to maintain a constant tension on the fiber. The tension adjusting device includes a sensor and a control device. The sensor detects the tension of the fiber passing through the second guide wheel, and the control device flexibly adjusts the position of the second guide wheel according to the tension magnitude to maintain a constant fiber tension. When the sensor detects excessive tension on the fiber, the control device controls the second guide wheel to move upward to balance the tension; when the sensor detects insufficient tension on the fiber, the control device controls the second guide wheel to move downward to balance the tension. The cooperation between the tension adjusting device and the second guide wheel allows for more sensitive control of the fiber tension passing through the second guide wheel, achieving smooth fiber unwinding.

[0010] In one embodiment, the first guide wheel, the second guide wheel, the third guide wheel, and the fourth guide wheel guide the continuous alumina fibers through a predetermined path for the fiber splitting process and stabilize the fiber tension.

[0011] In one implementation, the winding die can be replaced to adapt to the winding of fibers on a specific die in different twisting devices.

[0012] In one embodiment, a first servo motor drives a winding mold fixed on a base to rotate, and a second servo motor drives a slide table to reciprocate. The slide table moves the base, and the winding mold, fixed on the base, reciprocates with the slide table, thereby improving the accuracy of fiber winding.

[0013] In one embodiment, the base clamps the winding die using a pneumatic clamping method, which makes the wound fibers more uniform.

[0014] In one implementation, a touchscreen human-computer interaction device is used to achieve flexible control over the machine's operating status.

[0015] In one embodiment, alumina continuous fibers are precisely fitted to a specific mold of the twisting device for fiber splitting.

[0016] In one implementation, the space occupied is reduced by integrating the unwinding machine and the winding machine in the vertical direction, and the number of workstations is reduced by concentrating them on one machine, thus saving labor costs.

[0017] An automatic yarn feeding device is located on the machine platform. The first guide wheel and the second guide wheel are located above the automatic yarn feeding device. The second guide wheel is located below the first guide wheel and cooperates with the tension adjustment device. The third guide wheel is located inside the first guide wheel on the same horizontal plane. The fourth guide wheel is located to the right of the third guide wheel on the same horizontal line. The clip-on yarn guide frame is located below the fourth guide wheel. The winding die is located on the base. The first servo motor is set on the left side of the base. The winding die, the base and the first servo motor are located on the slide table. The second servo motor is set on the left side of the slide table. A touch screen human-machine interaction device is set on the outside of the slide table.

[0018] Advantages of this utility model:

[0019] This invention proposes an integrated fiber splitting machine specifically for continuous alumina fibers. It improves the precision of the winding device by replacing the chain drive with a first servo motor, and enhances the precision of fiber alignment control by replacing the fiber guide with a second servo motor. Furthermore, by setting the rotational speed of the first servo motor and the reciprocating distance of the second servo motor, the two servo motors work together to improve the quality of the wound fibers. A tension adjustment device maintains stable fiber tension, and the unwinding and winding devices are integrated vertically, reducing space occupation. The workstations are concentrated on a single machine, reducing manual labor and saving labor costs. A touchscreen human-machine interface allows for real-time monitoring of the machine's operating status, improving equipment flexibility. The fiber splitting machine proposed in this invention can achieve speeds 3-5 times faster than traditional fiber splitting machines, significantly improving work efficiency.

Detailed Implementation

[0022] The following is a detailed description of this utility model.

[0023] Example 1

[0024] like Figure 1 As shown, this embodiment provides an integrated splitting machine for continuous alumina fibers, including an automatic feeding device 1, a tension adjusting device 2, a first guide wheel 3, a second guide wheel 4, a third guide wheel 5, a fourth guide wheel 6, continuous alumina fibers 7, a jacketed guide frame 8, a winding mold 9, a base 10, a first servo motor 11, a slide table 12, a second servo motor 13, and a touch screen human-machine interaction device 14.

[0025] An automatic yarn feeding device 1 is located on the machine platform. The first guide wheel 3 and the second guide wheel 4 are located above the automatic yarn feeding device 1. The second guide wheel 4 is located below the first guide wheel and cooperates with the tension adjustment device 2. The third guide wheel 5 is located inside the first guide wheel 3 on the same horizontal plane. The fourth guide wheel 6 is located to the right of the third guide wheel 5 on the same horizontal line. The clamping yarn guide frame 8 is located below the fourth guide wheel 6. The winding die 9 is located on the base 10. The first servo motor 11 is set on the left side of the base 10. The winding die 9, the base 10 and the first servo motor 11 are located on the slide table 12. The second servo motor 13 is set on the left side of the slide table 12. The touch screen human-machine interaction device 14 is set on the outside of the slide table 12.

[0026] The automatic unwinding device 1 unwinds the continuous alumina fiber 7 from the large roll at a uniform speed; the fiber is guided to the first guide roller 3 and the second guide roller 4; the tension of the fiber is adjusted by the tension adjusting device 2; after passing through the tension adjusting device 2, the continuous alumina fiber passes through the third guide roller 5 and the fourth guide roller 6 to maintain the stability of the fiber tension; then it passes through the jacketed guide frame 8 to further adjust the fiber tension and guide the fiber to be wound onto the winding die 9 fixed by the base 10; the first servo motor 11 drives the fiber to be wound onto the winding die 9 at a uniform speed; the second servo motor 13 drives the base 10 to reciprocate on the slide table 12; the winding die 9 reciprocates while winding, and the continuous alumina fiber is distributed on the winding die 9 with appropriate tension and uniform density; the equipment is directly controlled by the touch screen human-machine interface device 14, making the equipment operation more convenient.

[0027] The working principle of this utility model:

[0028] Alumina continuous fibers are drawn out from the automatic feeding device 1, first passed through the first guide roller 3 and then to the second guide roller 4. The second guide roller 4 maintains the tension of the fibers by controlling the tension adjustment device 2, and then guides the fibers to the third guide roller 5 and then to the fourth guide roller 6 in the horizontal direction. After being guided by the fourth guide roller 6, the fibers are transferred to the jacketed guide frame 8 and finally wound onto the winding die 9.

[0029] The tension adjustment device 2, in conjunction with the second guide roller 4, can detect the fiber tension in real time to maintain a constant tension on the fiber. The tension adjustment device 2 includes a sensor and a control device. The sensor detects the tension of the fiber passing through the second guide roller 4, and the control device flexibly adjusts the position of the second guide roller 4 according to the tension level to maintain a constant fiber tension. When the sensor detects excessive tension on the fiber, the control device moves the second guide roller 4 upward to balance the tension; when the sensor detects insufficient tension on the fiber, the control device moves the second guide roller 4 downward to balance the tension. The cooperation between the tension adjustment device 2 and the second guide roller 4 allows for more sensitive control of the fiber tension passing through the second guide roller, achieving smooth fiber unwinding.

[0030] The first servo motor 11 drives the winding mold 9 fixed on the base 10 to rotate, so that the fiber is wound on the winding mold 9. The second servo motor 13 drives the base 10 to reciprocate on the slide table 12, so that the fiber is evenly arranged on the winding mold 9. The equipment operation can be flexibly controlled by the touch screen human-machine interaction device 14.
