Description

Technical Field

[0001] This utility model relates to the field of glass fiber manufacturing technology, and in particular to a high-precision quartz fiber cotton production device using a pressure roller. Background Technology

[0002] Quartz wool is a fibrous material made from quartz powder with a silica content of not less than 99.9%. Due to its excellent high temperature resistance, insulation, low thermal conductivity and strong chemical stability, it is widely used as a heat insulation and heat preservation material for high-temperature furnaces in industries such as metallurgy, glass, and ceramics. It can effectively reduce heat loss and improve energy utilization efficiency. The production of quartz wool requires a series of complex processes such as high-temperature melting and drawing of quartz powder.

[0003] Early feeding mechanisms often used simple mechanical transmission methods such as chain drive or gear drive. These methods made it difficult to precisely control the forward speed of the quartz rod, resulting in inconsistent quartz rod thickness during the processing of the quartz rod into quartz filaments. Furthermore, the diameter of the quartz rod varied during production. When the subsequent blowing process was used to manufacture quartz fiber cotton, the large error in the diameter of the single filament resulted in inconsistent quality of the produced quartz fiber cotton, failing to meet the high-precision requirements of high-end applications. Therefore, a pressure roller-type high-precision quartz fiber cotton production device is proposed. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a high-precision quartz fiber cotton production device using a pressure roller, aiming to improve the problem of unstable quartz rod forward speed and uneven thickness of drawn quartz filaments in the existing technology. When the subsequent blowing process is carried out to manufacture quartz fiber cotton, the diameter error of the single filament is relatively large, resulting in inconsistent quality of the produced quartz fiber cotton.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1-3 This utility model provides an embodiment of a high-precision quartz fiber cotton production device using a pressure roller, comprising a frame 1. The frame 1 serves as the supporting structure for the entire device, providing the mounting foundation for each component and ensuring the stability of the device. Multiple quartz rod positioning plates 2 are fixedly connected along the length of the top right side of the frame 1. The function of the quartz rod positioning plates 2 is to accurately position the quartz rods, ensuring they maintain a stable position during production. A feeding mechanism is located on the top center side of the frame 1. A primary burner 15, a laser diameter measuring module 16, a quartz filament traction mechanism 17, and a flame blowing mechanism 18 are sequentially installed along the length of the top left side of the frame 1. The primary burner 15 converts the quartz rods into fine quartz filaments by melting and stretching the quartz rods into fine quartz filaments through high temperature. The laser diameter measuring module 16 detects the diameter of the fine quartz filaments, monitoring their diameter in real time using laser measurement technology. The quartz filament traction mechanism 17 tractions the fine quartz filaments, ensuring smooth movement on the production line and maintaining the continuity of the production process. The flame blowing mechanism 18 is used to further process the fine quartz filaments by changing their shape or properties through flame blowing to meet the requirements for producing high-precision quartz fiber cotton.

[0033] Reference Figure 5The feeding mechanism includes two motor mounting plates 3, a support plate 6, and a fixing plate 10. The motor mounting plates 3 are fixedly connected to the bottom middle side of the frame 1. The quartz rod positioning plate 2 provides a stable mounting platform for the servo motor 4, reducing the impact of vibration generated by the servo motor 4 during operation on the frame 1 and other components. The support plate 6 is fixedly connected to the middle of the frame 1, providing rotational support for the first rotating shaft 7 and ensuring smooth rotation of the first rotating shaft 7. The fixing plate 10 is fixedly connected to the outer wall of the first-stage burner 15, providing an installation position for the rotating shaft mounting plate 11, thus keeping the relative position of the entire feeding mechanism and the first-stage burner 15 fixed. Multiple servo motors 4 are fixedly connected to the opposite side of each motor mounting plate 3. The servo motors 4 have high-precision speed and torque control capabilities, and can accurately adjust the feeding speed according to production needs. The output end of the servo motor 4 is fixedly connected to a first worm gear 5. When the servo motor 4 starts, its output shaft drives the first worm gear 5 to rotate synchronously, providing power for the entire feeding mechanism. Multiple first rotating shafts 7 are rotatably connected to the middle of the support plate 6. The bottom of the first rotating shaft 7 is fixedly connected to a first worm wheel 8, and the top of the first rotating shaft 7 is fixedly connected to a second worm gear 9. When the first worm gear 5 rotates, it drives the first worm wheel 8 and the first rotating shaft 7 to rotate through the worm gear-worm wheel transmission principle. The second worm gear 9, fixed at the top of the first rotating shaft 7, rotates together with the first rotating shaft 7, transmitting power to the next stage of transmission. Multiple rotating shaft mounting plates 11 are fixedly connected to the side of the fixed plate 10 away from the first-stage burner 15. The rotating shaft mounting plates 11 provide the mounting base for the second rotating shaft 12, ensuring the stability of the second rotating shaft 12 during operation. Two second rotating shafts 12 are rotatably connected between two adjacent rotating shaft mounting plates 11. A pressure roller 13 is fixedly connected to the middle of the outer wall of the second rotating shaft 12, and a second worm wheel 14 is fixedly connected to the edge of the outer wall of the second rotating shaft 12. When the second worm gear 9 rotates, it drives the second worm wheel 14 and the second rotating shaft 12 to rotate, thereby causing the pressure roller 13 to rotate and realize the feeding of quartz rods.

[0034] Reference Figure 4 The first-stage burner 15 is used to convert the quartz rod into a fine quartz filament. The first-stage burner 15 softens the quartz rod by heating it at high temperature, and then draws it into a fine quartz filament under the traction of the quartz filament traction mechanism 17.

[0035] Reference Figure 3 The flame blowing mechanism 18 includes a mounting plate, on which multiple flame blowers are fixedly connected. The multiple flame blowers are mounted on the side plate and can simultaneously blow fine quartz filaments into quartz fiber cotton.

[0036] Reference Figure 3The quartz wire traction mechanism 17 includes two side plates, and two rollers are rotatably connected between the two side plates. With the support of the side plates, the two rollers can apply a stable traction force to the softened quartz rod by rotation, and draw it evenly into fine quartz wire.

[0037] Reference Figure 4 The laser diameter measuring module 16 contains the same number of measuring components as the quartz rod. Each measuring component is fed back to the corresponding servo motor 4 through the central control system. The laser diameter measuring module 16 is used to detect the diameter of the fine quartz filament. When the laser diameter measuring module 16 detects a change in the diameter of the fine quartz filament, it can quickly transmit the change information to the central control system. The central control system adjusts the speed of the corresponding servo motor 4 in a timely manner based on this information, thereby adjusting the feed speed of the quartz rod, correcting the diameter of the fine quartz filament, and ensuring that the diameter of the monofilaments of the produced quartz fiber cotton is uniform.

[0038] Reference Figure 5 The first worm 5 meshes with the first rotating shaft 7, and the second worm wheel 14 meshes with the second worm 9. When the servo motor 4 starts, its output drives the first worm 5 to rotate. Because the first worm 5 meshes with the first rotating shaft 7, the rotation of the first worm 5 drives the first rotating shaft 7 to rotate, which in turn drives the second worm 9 at the top of the first rotating shaft 7 to rotate. Furthermore, because the second worm wheel 14 meshes with the second worm 9, the rotation of the second worm 9 drives the second worm wheel 14 to rotate, thereby driving the second rotating shaft 12, which is fixedly connected to the second worm wheel 14, to rotate, ultimately achieving the rotation of the pressure roller 13.

[0039] Reference Figure 5 The first worm gear 8 and the second worm gear 14 are arranged in opposite staggered positions, which can save more space. The outer wall of the quartz rod is slidably connected to the inner wall of the quartz rod positioning plate 2 and the fixing plate 10. The sliding connection can ensure the stability of the quartz rod during the feeding process and allow it to move smoothly when subjected to external forces.

[0040] Reference Figure 5 The outer wall of the quartz rod is slidably connected between two pressure rollers 13. During the feeding process, the two pressure rollers 13 rotate and drive the quartz rod forward through the friction with the outer wall of the quartz rod.

[0041] Working principle: The quartz rod is passed through the quartz rod positioning plate 2, the rotating shaft mounting plate 11 and the second rotating shaft 12 in sequence. Then the first-stage burner 15 is ignited and the servo motor 4 is started. When the servo motor 4 rotates, its output shaft drives the first worm 5 to rotate synchronously. Since the first worm 5 and the first rotating shaft 7 are meshed, the rotation of the first worm 5 drives the first rotating shaft 7 to rotate, which in turn drives the second worm 9 at the top of the first rotating shaft 7 to rotate. Furthermore, because the second worm gear 14 meshes with the second worm 9, the rotation of the second worm 9 drives the second worm gear 14 to rotate, thereby driving the second rotating shaft 12, which is fixedly connected to the second worm gear 14, to rotate, ultimately realizing the rotation of the pressure roller 13. When the pressure roller 13 rotates, it will transport the quartz rod through friction. After the front end of the quartz rod passes the first-stage burner 15, the worker will pull the softened quartz rod into the quartz wire pulling mechanism 17. The quartz wire pulling mechanism 17 will draw the quartz rod into fine quartz wire. After the fine quartz wire passes the flame blowing mechanism 18, the flame blowing mechanism 18 will be ignited, blowing the fine quartz wire into quartz fiber cotton.

[0042] When the quartz filament traction mechanism 17 draws the fine quartz filaments, the filaments pass through the laser diameter measuring module 16. The laser diameter measuring module 16 contains the same number of measuring components as the quartz rod. Each measuring component interacts with its corresponding servo motor 4 via a central control system. The laser diameter measuring module 16 measures the diameter of each fine quartz filament in real time. When the diameter of the fine quartz filament changes, the laser diameter measuring module 16 transmits the change information to the central control system, which then adjusts the speed of the servo motor 4 to correct the diameter of the fine quartz filament. This ensures that the produced quartz fiber cotton has a more uniform filament diameter and better product stability.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
