[0022] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0023] Please refer to Figures 1 to 3 This application provides a glass fiber drawing structure, including: a filter assembly 100 disposed on a buckle plate, the filter assembly 100 having a filter hole portion 110; a protective portion 200 disposed on the filter assembly 100, the protective portion 200 surrounding the filter hole portion 110 to form a protective space 210; and a reinforcing member 300 disposed within the protective space 210 and connected to the protective portion 200 to support the protective portion 200.
[0024] The glass fiber drawing structure provided in this application includes a filter assembly 100, a protective part 200, and a reinforcing member 300. The filter assembly 100 is disposed on a stencil plate and has a filter hole portion 110. The protective part 200 is disposed on the filter assembly 100 and surrounds the filter hole portion 110 to form a protective space 210. The reinforcing member 300 is disposed within the protective space 210 and connected to the protective part 200 to support the protective part 200. By providing a protective part 200 around the filter hole section 110 to form a protective space 210, the protective part 200 blocks the crystals accumulated on the filter screen assembly 100 during the glass fiber drawing process, preventing the crystals from entering the filter hole section 110 and affecting the quality of the glass fiber. At the same time, the reinforcing part 300 supports the protective part 200 to prevent the protective part 200 from deforming under high temperature for a long time. Through optimized design, this structure reduces the clogging and impurity falling phenomenon that may occur during the drawing process, reduces the maintenance frequency and cost, and improves the drawing efficiency.
[0025] In this application, the filter assembly 100 includes a filter screen, and the filter hole portion 110 is preferably disposed above the stencil. The filter hole portion 110 includes multiple filter holes. The glass solution enters the interior of the stencil after passing through each filter hole. The filter assembly is a filter screen structure, and the filter hole portion 110 is disposed above the stencil. Since the composition of the glass solution changes according to actual needs, the difference between the crystallization temperature and the forming temperature of different glass components varies. Therefore, due to the temperature difference in different areas where the glass solution flows in, crystallized glass will be generated on the upper part of the stencil. These crystallized glasses will follow the glass solution through the filter holes into the interior of the stencil, thereby affecting the fiber drawing efficiency. By providing the protective portion 200, the precipitated crystals can be blocked, preventing the crystals from entering the filter hole portion and thus into the interior of the stencil, affecting the production quality of glass fiber.
[0026] Specifically, the protective part 200 includes a protective body 220, which is disposed on the filter assembly 100 and surrounds the filter hole portion 110. The protective body 220 includes a connecting end 221 and a free end 222. The connecting end 221 is connected to the filter assembly 100, and the free end 222 extends in a direction away from the filter assembly 100. The height of the protective body 220 is 10mm to 20mm, with the direction from the connecting end 221 to the free end 222 as the height direction. By setting the protective body 220 to surround the filter hole portion 110, a physical barrier is formed. The connecting end 221 of the protective body 220 is tightly connected to the filter assembly 100, ensuring the stability of the protective part. The free end 222 extends in a direction away from the filter assembly. This design increases the structural rigidity of the protective part 200 and reduces possible deformation and collapse under high temperature or gravity. The protective body 220 provides a more enclosed and controlled environment for the filter section 110, which helps maintain the accuracy of the wire drawing process, reduces the impact of external environmental factors on the wire drawing process, and thus improves the performance and production efficiency of the entire equipment.
[0027] In one embodiment provided in this application, such as Figure 1 As shown, the protective body 220 includes two opposing side walls, with the two ends of the reinforcing member 300 connected to the opposing side walls respectively. The connection design between the reinforcing member 300 and the side walls significantly enhances the compressive and bending resistance of the protective body 220, thereby improving the stability of the entire wire drawing structure during the wire drawing process and reducing the risk of damage due to vibration or external impact.
[0028] In its implementation, the protective body 220 includes a first body 223, a second body 224, a third body 225, and a fourth body 226 connected sequentially. The first body 223 and the third body 225 are positioned opposite each other, and the fourth body 226 and the second body 224 are positioned opposite each other. The two ends of the reinforcing member 300 are connected to the first body 223 and the third body 225 respectively; or, the two ends of the reinforcing member 300 are connected to the fourth body 226 and the second body 224 respectively. This multi-point connection between the reinforcing member 300 and the protective body 220 increases the structure's durability, maintaining its shape and function even during long-term use or in harsh environments, reducing the need for maintenance and replacement. Furthermore, during the high-temperature process of glass fiber drawing, the connection between the reinforcing member 300 and the protective body 220 optimizes the heat conduction path, reduces the concentration of thermal stress, thereby improving thermal stability and ensuring the continuity of the drawing process and product quality. The protective body 220 consists of four main parts, forming a closed protective space. The connection between the two ends of the reinforcing component 300 and the opposite main body can further enhance the sealing effect and prevent external environmental interference to the internal wire drawing part, such as dust and humidity, thus protecting the cleanliness and quality of the wire drawing process.
[0029] In this application, the reinforcing member 300 is a reinforcing plate 310, and the bottom surface of the reinforcing plate 310 is at a predetermined distance from the filter hole portion 110; the predetermined distance is 8mm to 12mm; the thickness of the reinforcing plate 310 is 0.5mm to 1.2mm. The arrangement of the reinforcing plate 310, especially the predetermined distance of 8mm to 12mm between its bottom surface and the filter hole portion 110, can significantly enhance the mechanical strength and structural stability of the entire glass fiber drawing structure. This design helps to support the protective portion 200 and prevent deformation or collapse during the high-temperature drawing process.
[0030] In this application, the reinforcing component 300 is a reinforcing plate 310, and there are at least two reinforcing plates 310, which are arranged crosswise within the protective space 210. By crosswise arranging multiple reinforcing plates 310, the overall rigidity and deformation resistance of the wire drawing structure can be significantly improved, especially under high temperature and tensile stress conditions, effectively preventing the collapse or deformation of the protective part. The crosswise reinforcing plates 310 can disperse the stress acting on the wire drawing part, avoiding stress concentration, thereby reducing the risk of breakage during the wire drawing process and improving the continuity of the wire drawing operation and product quality. The crosswise arrangement of the reinforcing plates 310 within the protective space helps to form a tighter protective structure, reducing the possibility of external impurities entering the wire drawing part, thereby improving the purity and performance of the wire drawing product.
[0031] In this application, the filter assembly 100 includes an inlet end face 120 and an outlet end face disposed opposite to each other, and a protective part 200 is disposed on the inlet end face 120. The inlet end face 120 serves as the inlet for materials such as molten glass to enter the filter pore section 110. The protective part 200 disposed on the inlet end face 120 can act as a first barrier to isolate the heat conduction of high-temperature materials from the filter pore section 110 to the filter assembly 100, and can also prevent the crystals accumulated on the filter screen from flowing into the filter pore section 110.
[0032] In another embodiment provided in this application, such as Figure 3As shown, the protective part 200 includes a protective body 220, which surrounds the filter hole part 110. The reinforcing member 300 is a reinforcing rib 320, which is disposed on the protective body 220 and extends along the height direction of the protective body 220. Multiple reinforcing ribs 320 are spaced apart along the extension direction of the protective body 220. This design, where the reinforcing ribs 320 extend along the height direction of the protective body 220 and are spaced apart, effectively enhances the structural strength and deformation resistance of the protective part 200. Especially in high-temperature, high-pressure industrial wire drawing environments, it prevents the protective body from twisting or collapsing due to external forces or thermal expansion and contraction. The spaced arrangement of multiple reinforcing ribs 320 along the extension direction of the protective body 220 ensures even distribution of stress acting on the protective body 220, avoiding stress concentration points and thus improving the durability and safety of the entire structure. The combined use of reinforcing rib 320 and protective body 220 not only provides physical protection, but also improves the resistance of the protective part to accidental impact by increasing the complexity of the structure, ensuring that the wire drawing part can be fully protected under various operating conditions.
[0033] The reinforcing rib 320 includes a first end and a second end arranged opposite to each other. The first end is positioned closer to the filter hole portion 110 than the second end. The width of the reinforcing rib 320 gradually increases from the first end to the second end. This gradually increasing width design better adapts to stress changes within the protective space 210, allowing for a reasonable distribution of the strength and rigidity of the reinforcing rib 320 in different areas, avoiding stress concentration, and thus improving the stability and lifespan of the structure. Near the filter hole portion 110, the width of the reinforcing rib 320 is smaller, facilitating material flow; while further away from the filter hole portion, the gradually increasing width provides stronger support, effectively preventing the collapse of the protective portion 200 under high temperatures, ensuring the continuity of the wire drawing operation and product quality.
[0034] This application also provides a glass fiber production equipment, including a glass fiber drawing structure and an equipment body. The glass fiber drawing structure is disposed on the equipment body, and the glass fiber drawing structure is the glass fiber drawing structure of the above embodiment.
[0035] The introduction of reinforcing components 300 in the fiber drawing structure, especially the combination of reinforcing plate 310 and protective section 200, enables the equipment to operate stably under higher temperatures and pressures, reducing common clogging and impurity shedding phenomena during the fiber drawing process, and improving fiber drawing continuity and production efficiency. The space created by the protective section 200 effectively isolates the filter section 110 from external environmental interference, reducing the risk of material contamination and deterioration during the fiber drawing process, thereby improving the purity and mechanical properties of the glass fiber and ensuring the consistency and high quality of the final product. The addition of reinforcing plate 310 improves the overall structural strength of the equipment, reducing equipment damage or malfunctions caused by high temperatures or high stress, while also providing a safer working environment for operators and reducing the incidence of production accidents.
[0036] Specifically, in this application, the filter assembly 100 is a filter structure, which is set on the spinneret for fiber drawing. Since the composition of the glass solution changes according to actual needs, the difference between the crystallization temperature and the forming temperature of different glass components varies. Therefore, due to the temperature difference in different areas where the glass solution flows in, crystallized glass will be generated on the upper part of the spinneret. This crystallized glass will follow the glass solution through the filter holes into the interior of the spinneret, thereby affecting the fiber drawing efficiency. By setting a protective part 200 around the drawing hole, the overflow of the precipitated crystals can be effectively blocked, thereby improving the production quality of glass fiber.
[0037] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:
[0038] The glass fiber drawing structure provided in this application includes a filter assembly 100, a protective part 200, and a reinforcing member 300. The filter assembly 100 is provided with a filter hole portion 110. The protective part 200 is disposed on the filter assembly 100 and surrounds the filter hole portion 110 to form a protective space 210. The reinforcing member 300 is disposed within the protective space 210 and connected to the protective part 200 to support the protective part 200. By providing a protective part 200 around the filter hole section 110 to form a protective space 210, the protective part 200 blocks the crystals precipitated on the filter screen assembly 100 during the glass fiber drawing process, preventing the crystals from entering the filter hole section 110 and affecting the quality of the glass fiber. At the same time, the reinforcing part 300 supports the protective part 200 to prevent it from deforming under high temperature for a long time. Through optimized design, this structure reduces the possible clogging and impurities falling into the drawing holes of the stencil during the drawing process, reduces maintenance frequency and cost, and improves drawing efficiency.
