Description
Technical Field
[0001] This utility model relates to the field of basalt fiber technology, specifically to a continuous drawing device for basalt fiber production. Background Technology
[0002] Basalt fiber is a novel inorganic, environmentally friendly, and high-performance fiber material. It is produced by melting basalt rock at 1450℃-1500℃ and then drawing it at high speed through a platinum-rhodium alloy spinneret. This fiber not only boasts high strength but also possesses excellent properties such as electrical insulation, corrosion resistance, and high-temperature resistance. It has broad application prospects in various industries, including fiber-reinforced composites, friction materials, shipbuilding materials, thermal insulation materials, the automotive industry, high-temperature filter fabrics, and protective applications. The increasing market demand for basalt fiber has prompted relevant enterprises and research institutions to develop equipment capable of efficiently producing continuous basalt fiber.
[0003] In current continuous basalt fiber drawing equipment, the drawing rollers and drive motors are generally connected by rigid bolts. This design requires multiple bolt removals using specialized tools after the winding process, resulting in cumbersome and time-consuming operations, leading to low roller replacement efficiency and directly impacting production continuity. Furthermore, due to the lack of buffering performance in bolt connections, the mechanical vibrations and transmission impacts from the motor cannot be effectively absorbed during high-speed operation, easily causing quality defects such as basalt fiber breakage and uneven winding tightness. Rigid impacts also exacerbate the wear of transmission components such as bearings and couplings, generating significant mechanical noise during equipment operation. This not only shortens equipment lifespan but also negatively impacts the on-site working environment. Based on this background, designing a continuous basalt fiber drawing device can effectively solve the problem of difficult roller removal in existing drawing equipment, which has significant practical implications. Utility Model Content
[0004] The purpose of this utility model is to provide a continuous drawing device for basalt fiber production, solving the following technical problems: In current continuous basalt fiber drawing equipment, the drawing roller and drive motor generally adopt a bolted rigid connection structure. After the winding process is completed, this design requires the use of special tools to disassemble the bolts multiple times, which is cumbersome and time-consuming, resulting in low efficiency of drawing roller replacement and directly affecting the continuity of production. In addition, due to the lack of buffering performance of bolted connections, the mechanical vibration and transmission impact output by the motor cannot be effectively absorbed during high-speed operation, which can easily cause quality defects such as basalt fiber breakage and uneven winding layer tightness. Rigid impacts also aggravate the wear of transmission components such as bearings and couplings, and generate significant mechanical noise during equipment operation, which not only shortens the service life of the equipment but also has a negative impact on the on-site working environment.
[0005] The objective of this utility model can be achieved through the following technical solution: A continuous drawing device for basalt fiber production, comprising a heating box, wherein a drawing die is provided at the bottom of the heating box, characterized in that a cooling box is provided at the lower end of the heating box, a drawing box is provided at the lower end of the cooling box, a drawing assembly is provided inside the drawing box, the drawing assembly includes a drawing roller disposed inside the drawing box, a connecting block is provided at one end of the drawing roller, an mounting block is provided at one end of the inner sidewall of the drawing box, a limiting component is provided inside the mounting block, the limiting component includes a limiting rod slidably disposed inside the mounting block, a limiting block is fixedly disposed at the end of the limiting rod, and a groove matching the limiting block is opened at one end of the connecting block.
[0006] As a further embodiment of this utility model: a limiting plate is sleeved on one end of the limiting rod away from the limiting block, and a first reset spring is sleeved on the limiting rod and fixed between the limiting block and the limiting plate.
[0007] As a further embodiment of this utility model: a support shaft is provided at the other end of the drawing roller, and a mounting box for connecting the support shaft is provided at one end of the inner sidewall of the drawing box. A connecting column is provided inside the mounting box, and a connecting sleeve is slidably fitted on the outer surface of the connecting column. A connecting plate is fixedly provided at one end of the connecting sleeve near the drawing roller, and a second return spring is provided inside the connecting sleeve and fixed to the connecting plate and the connecting column.
[0008] As a further embodiment of this utility model: one end of the support shaft is configured as a square snap-fit structure, the end of the connecting plate near the support shaft is provided with a snap-fit groove, and a limit pin is provided between the connecting plate and the support shaft.
[0009] As a further aspect of this utility model, the length of the mounting box is greater than the reciprocating movement length of the cylinder.
[0010] As a further embodiment of this utility model: a servo motor is provided at one end of the outer side of the wire drawing box, and the output shaft of the servo motor is fixedly connected to the mounting box through a bearing. A cylinder is provided at the other end of the outer side of the wire drawing box, and the end of the piston rod of the cylinder is rotatably connected to the mounting block.
[0011] As a further embodiment of this utility model: a grid plate is symmetrically arranged on the upper end of the cooling box directly below the wire drawing plate, and a cold air fan is symmetrically fixed on the upper end of the cooling box.
[0012] As a further embodiment of this utility model: an annular tube is provided inside the cooling box directly below the wire drawing plate, and multiple nozzles are arranged in an array on the inner side of the annular tube.
[0013] The beneficial effects of this utility model are:
[0014] (1) The limiting block and limiting groove of this utility model can be used to quickly install and disassemble the drawing roller. During the operation of the drawing roller, the connecting column slides in the connecting sleeve and squeezes the second return spring. The second return spring plays a buffering role, reducing the impact and collision between the parts, and avoiding the basalt fiber breakage or uneven winding caused by severe impact. The cylinder drives the drawing roller to move back and forth, making the winding on both sides more uniform, effectively avoiding the problem of excessive fiber accumulation in the middle and insufficient winding on both sides.
[0015] (2) The air cooler set in this utility model can quickly improve the cooling efficiency of basalt fiber filaments. The grid plate effectively prevents the fiber from getting tangled on the air cooler components. After air cooling, water is sprayed evenly from the nozzle through the ring pipe and sprayed onto the fiber filaments in a spraying manner. Combining the advantages of air cooling and water cooling, the fiber filaments are first initially cooled by air cooling to reduce the temperature of the fiber filaments, and then further cooled by water cooling to achieve a more ideal cooling effect. This fully utilizes the advantages of the two cooling methods and improves cooling efficiency and quality.

[0026] In the field of basalt fiber technology, the cooling and disassembly of continuous drawing equipment for basalt fiber production have a significant impact on its production quality and efficiency. This invention addresses the shortcomings of traditional basalt fiber drawing devices, such as poor cooling performance and difficulties in drum installation and disassembly, by implementing a series of innovative designs to achieve efficient cooling and rapid disassembly. The specific implementation method is as follows:
[0027] Example 1: As Figure 1 , Figure 2 As shown, a continuous drawing device for basalt fiber production includes a heating box 1, in which basalt ore is melted into a liquid state. The upper end of the heating box 1 is provided with a feed inlet, the bottom of the heating box 1 is provided with a drawing plate 2, and the lower end of the heating box 1 is provided with a cooling box 3. The cooling box 3 is used to rapidly cool the basalt so that it can be quickly solidified to form continuous fiber filaments. If it is not cooled in time, the high-temperature fibers may break or stick together into coarse fibers due to surface tension, affecting uniformity. The lower end of the cooling box 3 is provided with a drawing box 4, and the drawing box 4 is provided with a drawing assembly 5. The drawing assembly 5 includes a drawing roller 51 provided inside the drawing box 4. The two ends of the drawing roller 51 are fixedly provided with baffles 52. The baffles 52 are mainly used to control the axial displacement of the fiber bundle, preventing it from deviating from the predetermined path or coming off the edge of the drawing roller 51 during the production process, ensuring that the fiber bundle always runs within the effective working area of the drawing roller 51, and reducing defects such as broken fibers and fuzzy fibers.
[0028] like Figure 3As shown, an installation block 6 is provided at one end of the inner wall of the wire drawing box 4. A limiting component 7 is provided inside the installation block 6. A through hole is provided at the end of the installation block 6 facing the wire drawing roller 51. A limiting groove perpendicular to the wire drawing roller 51 is provided at one end of the installation block 6. The limiting component 7 includes a limiting rod 71 that is slidably disposed inside the limiting groove. A limiting block 72 is fixedly provided at the end of the limiting rod 71. A limiting plate 73 is sleeved at the end of the limiting rod 71 away from the limiting block 72. The limiting plate 73 is fixedly connected to the inner wall of the limiting groove. A first return spring 74 is sleeved on the limiting rod 71 and fixed between the limiting plate 73 and the limiting block 72. A docking block 53 is provided at one end of the wire drawing roller 51. A slot 531 matching the limiting block 72 is provided on the docking block 53.
[0029] like Figure 4 As shown, a support shaft 54 is provided at the other end of the drawing roller 51. A mounting box 55 for sleeved support shaft 54 is provided at one end of the inner wall of the drawing box 4. A through hole is opened at the end of the mounting box 55 near the drawing roller 51. A connecting post 56 is fixedly provided in the through hole. A connecting sleeve 57 is slidably sleeved on the outer surface of the connecting post 56. A connecting plate 58 is fixedly provided at the end of the connecting sleeve 57 near the drawing roller 51. A second return spring 59 is provided inside the connecting sleeve 57 and fixed to the connecting plate 58 and the connecting post 56.
[0030] When the cylinder drives the drawing roller 51 to its end point, the second return spring 59 acts as a buffer, reducing impact and collision between components, decreasing equipment wear and noise, and extending the equipment's service life. It also prevents problems such as basalt fiber breakage or uneven winding that may occur due to severe impact.
[0031] A servo motor is installed at one end of the outer side of the wire drawing box 4. The output shaft of the servo motor passes through the side wall of the wire drawing box 4 through a bearing and is fixedly connected to the mounting block 6. A cylinder is installed at the other end of the outer side of the wire drawing box 4. The end of the piston rod of the cylinder is rotatably connected to the mounting box 55.
[0032] The servo motor drives the mounting block 6 to rotate, which in turn drives the drawing roller 51 to rotate, slowly winding the cooled basalt fiber onto the drawing roller 51. The cylinder is rotatably connected to the mounting block 6. The rotation of the servo motor does not drive the cylinder to rotate. While winding, the cylinder drives the mounting box 55 to move horizontally back and forth. The support shaft 54 slides back and forth inside the mounting box 55, thereby evenly winding the basalt fiber onto the drawing roller 51. The back and forth movement of the drawing roller 51 makes the winding on both sides more uniform, effectively avoiding the problem of excessive fiber accumulation in the middle and insufficient winding on both sides.
[0033] One end of the support shaft 54 is configured as a square snap-fit structure. The end of the connecting plate 58 near the support shaft 54 is provided with a snap-fit groove, which matches the square snap-fit structure at the end of the support shaft 54. A limit pin is provided between the connecting plate 58 and the support shaft 54. The limit pin is used to limit the relative displacement between the support shaft 54 and the connecting plate 58, so as to prevent the support shaft 54 from sliding out of the mounting box 55 during the winding process. The length of the mounting box 55 is greater than the reciprocating movement length of the cylinder during use. While ensuring that the wire drawing roller 51 can be wound evenly, the support shaft 54 will not slide out of the mounting box 55.
[0034] The support shaft 54 is square in design to ensure that there is no relative rotation between the support shaft 54 and the connecting plate 58 when the connecting plate 58 rotates. At the same time, the support shaft 54 and the connecting plate 58 will not move relative to each other by means of a limit pin.
[0035] Example 2: Based on Example 1, as follows Figure 5 As shown, a grid plate 81 is symmetrically arranged at the upper end of the cooling box 3 directly below the drawing plate 2. A cooler 82 is fixedly arranged on one side of the grid plate 81 at the upper end of the cooling box 3. The cooler 82 keeps the air circulating, which helps to improve the cooling efficiency of the basalt fiber. Rapid cooling helps to improve the performance of the fiber, such as giving it better strength and toughness, thus improving the quality of the basalt fiber. The grid plate 81 prevents the fiber from getting tangled on the components of the cooler 82, avoiding malfunctions of the cooler 82 due to blockage or component damage, extending the service life of the cooler 82, and reducing equipment maintenance costs.
[0036] Inside the cooling box 3, an annular tube 91 is arranged directly below the drawing plate 2. Multiple nozzles 92 are arranged in an array on the inner side of the annular tube 91. Inside the cooling box 3, a water tank 93 is arranged. The water tank 93 is connected to the annular tube 91 through a conduit. Water is pumped from the water tank 93 through a pump body. After passing through the annular tube 91, it is sprayed evenly from the nozzles 92 and sprayed onto the fiber in a spraying manner to achieve cooling.
[0037] Combining the advantages of air cooling and water cooling, the fibers are first initially cooled by air cooling to lower their temperature, and then further cooled by water cooling to achieve a more ideal cooling effect. This method can fully utilize the advantages of both cooling methods, improving cooling efficiency and quality.
[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
