Description

TECHNICAL FIELD

[0001] The patent application relates to the technical field of glass fiber drawing, in particular to a glass fiber drawing system. BACKGROUND

[0002] Glass fiber is an inorganic non-metallic material made of glass as raw material by high-temperature melting and drawing. It has excellent properties such as high strength, corrosion resistance, good insulation, light weight, etc., and is widely used in fields such as construction, transportation, electronics, aerospace, environmental protection, etc. The production process of glass fiber mainly includes raw material melting, drawing, surface treatment and finished product processing, etc. Drawing is one of the core processes. The glass fiber drawing machine is a key equipment specially used for forming glass fiber by high-speed drawing of molten glass liquid. Its main function is to spray the high-temperature molten glass liquid through the spinneret (or bushing), and form extremely fine glass fiber under the action of high-speed stretching. The performance of the drawing machine directly affects the diameter, strength and uniformity of the glass fiber, and is an indispensable core equipment in the production process of glass fiber.

[0003] However, the existing glass fiber drawing machine cannot adjust the position of the drawing roller. As the diameter of the fiber cake on the winding drum increases, although the linear speed of the winding point remains constant, its angular speed decreases. If the position of the drawing roller cannot be adjusted accordingly to compensate for the change in path length, the actual tension of the fiber during running will fluctuate significantly. If the tension is too large, it will easily cause fiber breakage (broken filament), resulting in production interruption, increased scrap rate, frequent jointing, and serious impact on continuous production efficiency. If the tension is too small, it may cause fiber relaxation, knotting, winding on the roller or formation of loose cake, and the fiber cannot accurately pass through the key area of the sizing agent applicator, resulting in insufficient and uneven coating or even missing coating.

[0004] Therefore, there is an urgent need for a glass fiber drawing system to solve the problems in the current technology.

[0033] See Figures 1-2 As shown, this embodiment provides a fiber drawing system for preparing glass fibers, including: a support mechanism 1, including a support base 101, a first support plate 102 and a second support plate 103. The support base 101 is fixedly connected to the first support plate 102 along the length direction, and the first support plate 102 is provided with a first through hole 104. The support base 101 is fixedly connected to the second support plate 103 along the width direction, and the second support plate 103 is located in the middle of the first support plate 102 and fixedly connected to the first support plate 102.

[0034] The moving mechanism 2 is located on both sides of the second support plate 103 and is slidably connected to the second support plate 103. The moving mechanism 2 passes through the through hole to the side of the first support plate 102 away from the second support plate 103.

[0035] The drive mechanism 3 is fixedly connected to the moving mechanism 2.

[0036] The collecting mechanism 4 includes a wire drawing roller assembly, a melting furnace 401, a wire drawing screen 402, and a cooling box 403. The melting furnace 401 is located above the wire drawing roller. The wire drawing screen 402 is provided at the outlet of the melting furnace 401. The cooling box 403 is provided at the bottom of the wire drawing screen 402. The wire drawing roller is rotatably connected to the moving mechanism 2, and the wire drawing roller is horizontally arranged on the side of the first support plate 102 away from the second support plate 103.

[0037] The spraying mechanism 5 is fixedly connected to the first support plate 102, and the spraying mechanism 5 is located below the cooling box 403.

[0038] Specifically, the support base 101 is fixedly connected with the first support plate 102 and the second support plate 103, the first through hole 104 is formed in the first support plate 102, the moving mechanism 2 is arranged on the second support plate 103, one end of the moving mechanism 2 extends through the first through hole 104 and extends to the side of the first support plate 102 away from the second support plate 103, the wire drawing roller assembly is rotatably connected to the side of the first support plate 102 extending out, the melting furnace 401 is arranged above the wire drawing roller assembly, the wire drawing sieve plate 402 and the cooling box 403 are arranged below the wire drawing roller assembly, after the glass fiber is melted in the melting furnace 401, the glass fiber is processed through the wire drawing sieve plate 402 and the cooling box 403, then the glass fiber is sprayed through the spraying mechanism 5, and finally the glass fiber is collected through the wire drawing roller assembly.

[0039] It can be understood that the support base 101 and the first support plate 102 and the second support plate 103 constitute a three-dimensional reference frame, and the five processes of melting, wire drawing, cooling, spraying and winding are compactly integrated along the vertical direction. The path of the glass fiber from the wire drawing sieve plate 402 to the wire drawing roller is physically constrained to a single axis, eliminating the fiber shaking and trajectory deviation caused by the separation of multiple modules in traditional equipment. The rotating traction force of the wire drawing roller is borne by the moving mechanism 2, and the vibration is dispersed through the side wall sliding surface of the second support plate 103 to avoid frame resonance. When the moving mechanism 2 drives the wire drawing roller to slide along the second support plate 103, the displacement amount is directly converted into linear adjustment of the fiber tension. When the roller is away from the cooling box 403, the fiber path is lengthened and the tension is reduced, which is suitable for flexible winding of high modulus fibers. When the roller is close to the cooling box 403, the path is shortened and the tension is increased, which meets the needs of tight winding of low elongation fibers.

[0040] In some embodiments of the present application, referring to Figure 3 As shown in the figure, the moving mechanism 2 includes a sliding block 201, a sliding plate 202 and a sliding rail 203, a plurality of sliding rails 203 are arranged on the two side walls of the second support plate 103, a plurality of sliding blocks 201 are arranged on each sliding rail 203, the plurality of sliding blocks 201 are slidably connected with the sliding rail 203, the sliding plate 202 is fixedly connected with the sliding block 201, and a second through hole 204 is formed in the middle of the sliding plate 202.

[0041] In some embodiments of the present application, a driving mechanism 3 is further included, the driving mechanism 3 includes a moving driving component 301 and a collecting driving component 302, the moving driving component 301 and the collecting driving component 302 are respectively located on the two side walls of the second support plate 103 and are fixedly connected with the moving mechanism 2.

[0042] Specifically, the second support plate 103 is provided with a plurality of slide rails 203 on both side walls, and a plurality of slide blocks 201 are arranged on the slide rails 203. The slide blocks 201 are fixedly connected with a sliding plate 202. A second through hole 204 is formed in the sliding plate 202. The second through hole 204 is used for the driving mechanism 3 to pass through the second through hole 204 to control the movement of the sliding plate 202. When the driving mechanism 3 starts to work, it controls the displacement of the sliding plate 202, and then the sliding plate 202 drives the slide blocks 201 to displace on the slide rails 203, thereby realizing the displacement control of the wire drawing roller assembly.

[0043] It can be understood that the slide rail 203 and the slide block 201 assembly are responsible for vertical compression stability, and uniformly transmit the radial load of the wire drawing roller to the second support plate 103. The sliding plate 202 serves as a horizontal displacement carrier, and its plane stiffness resists the fiber traction torque to avoid the eccentric bending moment borne by the slide block 201. The second through hole 204 realizes the motion decoupling of the driving shaft and the sliding plate 202, eliminates the interference of shaft system eccentricity on displacement accuracy, the slide rail 203 bears the normal pressure to ensure the anti-sinking ability, the sliding plate 202 bears the in-plane shear force to suppress the transverse vibration, the movement driving part 301 and the collection driving part 302 are separated on the two side walls of the second support plate 103, eliminating the cantilever effect of single-point driving, and avoiding the overturning of the sliding plate 202.

[0044] In some embodiments of the present application, the movement driving part 301 includes a movement driving motor 3011, a movement gear 3012 and a rack 3013. The output end of the movement driving motor 3011 penetrates the second through hole 204 into the cavity between the second support plate 103 and the sliding plate 202. The output end of the movement driving motor 3011 is fixedly connected with the movement gear 3012. The movement gear 3012 is engaged with the rack 3013.

[0045] In some embodiments of the present application, the collection driving part 302 includes a collection driving motor 3021, a driving large gear 3022, a driving small gear 3023 and a driving belt 3024. The output end of the collection driving motor 3021 penetrates the second through hole 204 into the cavity between the second support plate 103 and the sliding plate 202. The output end of the collection driving motor 3021 is fixedly connected with the driving large gear 3022. The driving small gear 3023 is located on the collection roller. The driving large gear 3022 and the driving small gear 3023 are connected through the driving belt 3024.

[0046] Specifically, the moving driving motor 3011 and the collecting driving motor 3021 are perpendicular to the direction of the slide plate 202, the output ends of the two motors pass through the second through hole 204 on the slide plate 202 and enter the gap between the slide plate 202 and the second support plate 103, the output end of the moving driving motor 3011 is fixedly connected with the moving gear 3012, when the moving driving motor 3011 starts to work, the moving gear 3012 is driven to move on the rack 3013, thereby realizing the displacement of the slide plate 202, and the output end of the mobile driving motor is connected with the driving gear 3022, the driving belt 3024 is driven through the driving gear 3022, thereby realizing the rotation of the driving pinion 3023, and the driving pinion 3023 is fixedly connected with the wire drawing roller component, thereby realizing the rotation of the wire drawing roller component.

[0047] It can be understood that the one-stage transmission topology from the moving driving motor 3011 to the moving gear 3012 to the rack 3013 realizes the direct conversion of electric energy to linear displacement, eliminates the backlash cumulative error of the multi-stage transmission of the traditional lead screw, chain and the like, the two-stage speed reduction structure of the driving gear 3022 to the driving belt 3024 to the driving pinion 3023, the gear as an inertial flywheel, smooth winding start-stop impact, the transmission of the motor vibration to the wire drawing roller is isolated by the belt drive, the quality of the fiber surface is guaranteed, the moving driving motor 3011 and the collecting driving motor 3021 enter the support plate cavity of the slide plate 202, the full-tooth-width meshing structure of the moving gear 3012 and the rack 3013 can automatically equalize the tooth surface pressure when the slide plate 202 is offloaded, the elastic deformation characteristic of the driving belt 3024 can absorb the instantaneous torque fluctuation of the collecting roller, and the rack 3013 is fixed to the inner wall of the second support plate 103, which can be directly maintained by disassembling the slide plate 202, the moving driving gear adopts a bidirectional check tooth shape, which can automatically lock the position of the slide plate 202 when power is off.

[0048] In some embodiments of the present application, referring to Figure 4 As shown in the figure, the spraying mechanism 5 includes a negative pressure oil coating component and an electrostatic forming component, and the negative pressure oil coating component and the electrostatic forming component are located on both sides of the wire drawing roller, and the electrostatic forming component is used to form an electrostatic field.

[0049] In some embodiments of the present application, the negative pressure oil coating component includes an oil coating shell 501, an oil atomizer assembly 502, an annular negative pressure ring 503 and an electrostatic generator 504, the oil coating shell 501 is located above the collecting roller and is fixedly connected with the first support plate 102, the oil coating shell 501 is provided with the oil atomizer assembly 502, the annular negative pressure ring 503 is arranged at the nozzle of the oil atomizer assembly 502, and the electrostatic generator 504 is electrically connected with the annular negative pressure ring 503.

[0050] In some embodiments of the present application, the static electricity forming component comprises a metal grid plate 505, which is located in the oiling shell 501, is opposite to the oil atomizer assembly 502, and is grounded, and is used to form an electric field between the oil atomizer assembly 502 and the metal grid plate 505.

[0051] Specifically, after the glass fiber bundle comes out of the cooling box 403, it passes through the inlet of the oiling shell 501, enters the oiling shell 501, passes through the jet position of the oil atomizer assembly 502, and moves downward, and the jet position of the oil atomizer assembly 502 is provided with an annular negative pressure ring, that is, when the oil mist passes through the negative pressure ring, a negative pressure is generated, and the oil mist is charged by corona discharge or direct contact, and the metal grid plate 505 is parallel to the oil atomizer assembly 502, that is, the glass fiber bundle falls between the metal grid plate 505 and the oil atomizer assembly 502, and the metal grid plate 505 is grounded, and then the oil mist passes through the glass fiber bundle to the position of the metal grid plate 505, thereby improving the effect of the oil mist.

[0052] It can be understood that by introducing electrostatic force, the droplet orientation, adhesion efficiency and uniformity in the glass fiber oiling process are improved. The core principle is to use high-voltage electrostatic field to charge the droplets and guide them to fly towards the fiber bundle, so as to realize more accurate and efficient oiling process. First, through the electrical connection of the electrostatic generator 504 and the annular negative pressure ring 503, the oil mist generates negative pressure when passing through the negative pressure ring, and is charged through corona discharge or direct contact, so as to improve the charging efficiency of the droplets and enhance the directionality of the droplets in the electric field. The charged droplets can fly more accurately to the fiber bundle under the action of the electric field, reducing the loss and waste of the droplets, thereby improving the efficiency and effect of oiling. Second, the metal grid plate 505 further optimizes the adhesion efficiency of the droplets. The metal grid plate 505 is located inside the oiling shell 501 and is oppositely arranged with the oil mist generator assembly 502 and is grounded. A stable electric field is formed between the oil mist generator assembly 502 and the metal grid plate 505, so that the charged droplets can more uniformly adhere to the fiber surface when passing through the glass fiber bundle. The grounding of the metal grid plate 505 not only ensures the stability of the electric field, but also prevents the unevenness of the droplets in the flight process due to static electricity accumulation, thereby improving the uniformity and consistency of the oiling. In addition, the atomizing nozzle usually adopts gas-assisted or ultrasonic atomizing technology, which can produce fine and uniform spray cloud. The metal ring or needle ring structure surrounding the nozzle outlet is directly connected to the high-voltage power supply, so that the atomized cloud can be charged through corona discharge or direct contact when passing through the annular electrode, ensuring the charging effect of the droplets. The entire charging structure is made of high-strength insulating material, ensuring the stability and safety of the equipment, and prolonging the service life of the equipment. The oiling shell 501 is made of transparent insulating material or metal frame plus insulating panel, which not only improves the insulation performance of the chamber, but also facilitates observation and monitoring of the oiling process. The use of transparent insulating material enables the operator to visually observe the distribution and adhesion of the droplets, and adjust the oiling parameters in a timely manner to ensure the stability and consistency of the oiling effect.

[0053] In some embodiments of the present application, the negative pressure oiling component further comprises an oil mist collector 506 located on one side of the metal grid plate 505, which is used to collect the oil mist sprayed by the oil mist generator assembly 502.

[0054] It can be understood that the oil mist collector 506, the metal grid plate 505 and the oil mist assembly 502 can be provided in multiple numbers, and the number, area or volume of the oiling shell 501 is set according to the number of glass fiber bundles, and the oil mist collector 506 improves the utilization rate of the oil mist. In the oiling process, the oil mist sprayed by the oil mist assembly 502 may not be completely attached to the glass fiber bundle due to various reasons (such as air flow, uneven distribution of static electricity, etc.), resulting in part of the oil mist being lost in the air. The oil mist collector 506 is located on one side of the metal grid plate 505, which can capture these unattached oil mists and collect them for reuse. Not only reduces the waste of oil mist, but also reduces the cost of oiling, improves the use efficiency of oil mist. Secondly, the oil mist collector 506 helps to reduce environmental pollution and health risks. In the traditional oiling process, unattached oil mist will spread into the air, not only causing waste of oil, but also possibly affecting the working environment and the health of the operator. The oil mist collector 506 collects these oil mists, reduces the spread of oil mist in the air, and reduces the possibility of environmental pollution. At the same time, this also improves the air quality of the working environment, reduces the risk of operators inhaling oil mist, and improves the safety and comfort of the working environment. In addition, the addition of the oil mist collector 506 further improves the stability and consistency of the oiling process. In the oiling process, uniform distribution and stable attachment of oil mist are key factors to ensure the effect of oiling. The oil mist collector 506 captures and recycles unattached oil mist, reducing uneven distribution of oil mist in the oiling chamber, avoiding fluctuations in oiling effect caused by oil mist accumulation or loss. Ensure the uniformity and consistency of the oil film on the surface of the glass fiber bundle, and improve the stability of the oiling quality.

[0055] In some embodiments of the present application, the drawing roller assembly includes a drawing roller, a collection shell 405 and a handle 406, the drawing roller is rotatably connected with the moving mechanism 2, the drawing roller 404 is annularly provided with a plurality of grooves 408 along the axis, the collection shell 405 is a hollow shell, the inner wall of the collection shell 405 is annularly provided with a plurality of protrusions 407 along the axis, the grooves 408 and the protrusions 407 correspond one by one, and one side of the mobile phone shell is fixedly connected with the handle 406.

[0056] It can be understood that, through the drawing roller assembly, including the drawing roller, the collection shell 405 and the handle 406, the convenience, efficiency and safety of the glass fiber bundle collection process are improved, and the operation difficulty and equipment maintenance cost are reduced. The structure of the drawing roller assembly not only optimizes the collection method of the glass fiber bundle, but also provides more convenience for the operation and maintenance of the equipment. First, the drawing roller assembly improves the convenience and efficiency of the glass fiber bundle collection. The drawing roller is rotatably connected with the moving mechanism 2, so that the glass fiber bundle can be uniformly wound on the drawing roller, avoiding the problem of uneven winding or accumulation of the fiber bundle during the collection process. The drawing roller is provided with a plurality of grooves 408 around the axis, which correspond to the protrusions 407 on the inner wall of the collection shell 405, so that the collection shell 405 can be quickly and accurately installed on the drawing roller. In actual operation, when the glass fiber bundle is collected to a certain amount, the operator only needs to hold the handle 406 to easily pull out the collection shell 405. When replacing the new collection shell 405, it only needs to push the protrusions 407 into the grooves 408. This convenient installation and disassembly method shortens the time for replacing the collection shell 405, improves the collection efficiency, and reduces the downtime during production. Second, the drawing roller assembly reduces the operation difficulty and equipment maintenance cost. In the traditional glass fiber bundle collection process, replacing the collection device usually requires complex operation steps and special tools, increasing the operation difficulty and maintenance cost. The technical scheme of the present application provides the handle 406, so that the operator can easily replace the collection shell 405 without the need for other tools or complex operations. Not only does it reduce the operation difficulty, but also reduces the labor intensity of the operator, improves the comfort and safety of the operation. At the same time, the cooperation of the collection shell 405 and the drawing roller reduces the wear and damage of the equipment during replacement, prolongs the service life of the equipment, and reduces the maintenance cost of the equipment.

[0057] The drawing system of the glass fiber in one of the above embodiments is directly linked with the drawing roller through the moving mechanism 2, so that the drawing roller can be actively displaced along the predetermined track. By adjusting the spatial position of the drawing roller in real time, the deformation stress of the fiber in the cooling and solidification, spraying and other links is directly compensated, the sudden change of tension caused by fiber shrinkage or speed fluctuation in the traditional equipment is eliminated, and the continuous winding of the fiber under constant tension is ensured. The response ability of the moving mechanism 2 to tension can absorb the internal stress of the fiber caused by sudden mechanical vibration or temperature gradient in the production process, avoid the broken filament caused by local overload, improve the stability of continuous operation, and the axis position of the drawing roller is dynamically matched with the fixed spraying mechanism 5 when the drawing roller is horizontally displaced through the moving mechanism 2. No matter what kind of process position the drawing roller is in, it can ensure that the fiber bundle strictly passes through the spraying core area, eliminate the mist droplet coverage blind area caused by the roller offset in the traditional equipment, and the structure of the moving mechanism 2 through the through hole of the first supporting plate 102 makes the drawing roller have controllable degrees of freedom in space. By fine-tuning the horizontal coordinates of the drawing roller through the driving mechanism 3, the development form of the fiber bundle with different diameters can be adapted, and it is ensured that each single filament is uniformly exposed to the spraying flow field. The rigid frame of the supporting base 101 and the double supporting plate provides a common reference installation plane for the moving mechanism 2, the collecting mechanism 4 and the spraying mechanism 5. The first supporting plate 102 serves as the "process axis", integrates the cooling, spraying and traction functions, shortens the path of the fiber from solidification to coating, and reduces environmental interference.

[0058] The operation process is as follows: firstly, the glass fiber solution is in the melting furnace 401, then passes through the bushing 402 to be divided into glass fiber bundles, and then enters the cooling box 403 for cooling, after the cooling is completed, the glass fiber bundle falls downward from the entrance of the oil spraying shell 501 in the spraying mechanism 5 into the oil spraying shell 501, the oil atomizer assembly 502 starts to work to spray oil mist, during the spraying process, when the oil mist reaches the nozzle of the oil atomizer assembly 502, the annular negative pressure ring is electrified by the electrostatic generator 504, and then the electrified oil mist flows to the falling glass fiber bundle, and the rear of the glass fiber bundle, i.e. the spraying direction of the nozzle, is provided with the grounded metal grid plate 505, the metal grid plate 505 further attracts the oil mist to increase the adhesion rate, the oil mist collector 506 beside the metal grid plate 505 absorbs the oil mist in the air which is not attached to the glass fiber bundle, at the same time, the oil atomizer assembly 502 can be provided with multiple parallel arrangements to increase the oil spraying area, and the moving mechanism 2 can control the position of the bushing roller and control the tension, the moving gear 3012 is driven to rotate by the moving driving motor 3011, the moving gear 3012 engages with the rack 3013 which is fixedly connected to the second support plate 103, at this time, the slide plate 202 drives the sliding block 201 to move on the slide rail 203, the driving motor 3021 rotates to drive the driving gear 3022 to rotate, the driving gear 3022 drives the driving belt 3024 to rotate, and then drives the driving pinion 3023 to rotate, so as to rotate the bushing roller shaft 404, when the mobile phone shell on the bushing roller shaft 404 collects a certain amount of glass fiber bundles, the handle 406 is pulled out to replace the new collection shell 405, and the convex 407 of the collection shell 405 is matched with the groove 408 on the bushing roller shaft 404, and the handle 406 is pushed in.

Therefore, if these modifications and variations of the present application fall within the scope of the claims of the present application and their equivalent technologies, the present application also intends to include these modifications and variations.
