Description

Technical Field

[0001] This invention relates to the field of precursor fiber production technology, specifically to a glass fiber precursor fiber production equipment. Background Technology

[0002] Glass fiber filament is the most basic product of glass fiber products. Glass fiber filament is unwound, twisted or wound, and its package form is changed to become glass fiber yarn for different purposes.

[0003] For example, Chinese patent publication number "CN114560629A" discloses "a glass fiber precursor production equipment". It uses a motor to drive the rotating shaft inside the conical cavity to re-crush larger glass raw materials, thereby improving the crushing efficiency of glass raw materials. It can also scrape off the molten raw materials on the inner wall of the reaction chamber to improve the utilization rate of glass raw materials and reduce the difficulty of cleaning the inner wall of the reaction chamber. However, when the glass fiber precursor production equipment is drawing, the glass solution leaks out from the stencil. Due to the influence of airflow or foreign objects sticking to the liquid, glass fibers may fly or break. After the fiber breaks, the winding operator needs to manually pull the whole bundle for about two to three minutes before it can be spun normally. This solution is too labor-intensive and there is a risk of burns during the drawing process.

[0004] To address this, Chinese Patent Publication No. CN114455829A discloses "A Glass Fiber Raw Material Production Equipment," which uses a transmission mechanism to provide power to the drawing mechanism and waste filament processing mechanism, thereby reducing the time required for manual drawing operations. However, while the drawing mechanism reduces the time required for manual drawing operations, the glass molten metal is in a vertically stacked state. The glass molten metal at the bottom is drawn through the perforations in the baffle plate. Therefore, during the drawing process, the glass molten metal at the drawing section is affected by the gravity of the glass molten metal above it. As the amount of glass molten metal continuously decreases, the drawing speed becomes uneven, and the drawing radius changes due to different pressures when the glass molten metal is extruded. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a glass fiber filament production device that uses a horizontal method to extrude and draw molten glass into filaments. By controlling the rotational speed of the drive motor, the pressure and speed of the glass solution during extrusion can be controlled, thereby maintaining stable drawing pressure and speed during the drawing process.

[0016] Compared with the prior art, the present invention provides a glass fiber precursor production equipment, which has the following beneficial effects:

[0017] This glass fiber precursor production equipment

[0018] 1. The glass in the molten state is extruded and drawn into fibers by a horizontal method. By controlling the speed of the drive motor, the pressure and speed of the glass solution during extrusion can be controlled, so that the glass solution maintains a stable drawing pressure and speed during the drawing process, thereby keeping the drawing speed uniform. At the same time, it can reduce the occurrence of uneven drawing radius during the drawing process.

[0019] 2. By setting up a crushing mechanism, the glass fed into the U-shaped feeding chamber is crushed by the rotating cutting and impact of the crushing rollers. After crushing, the glass fragments that meet the requirements will fall down through the arc-shaped filter plate and finally flow down through the falling channel, thereby achieving the crushing of the glass. The heated surface of the crushed glass is increased, so it can be heated and melted quickly, thereby improving the efficiency of melting the glass.

[0020] 3. By setting up a melting mechanism, when the broken glass comes into contact with the high-temperature spiral conveyor, it will be heated and melted by the spiral conveyor. Of course, by reducing the speed of the spiral conveyor, the melting time of the glass can be increased. The molten glass moves towards the conical feed chamber under the action of the rotating spiral conveyor. At the same time, the speed of the spiral conveyor is kept stable, so the thrust it generates is relatively stable. This allows control over the pressure and speed of the glass solution during extrusion, thereby maintaining stable drawing pressure and speed during the drawing process. Attached Figure Description

Before operation, the fixed base 2 needs to be fixedly installed on the ground or table, and the drive motor 1, as a power source, needs to drive the equipment to operate.

[0032] To achieve glass pulverization and thus improve the efficiency of glass melting, please refer to [link / reference needed]. Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 A crushing mechanism 4 needs to be set up, which is equipped with a crushing roller 47 that can rotate with the rotor 3 of the drive motor 1 and crush the surrounding glass products, and an arc-shaped filter plate 48 installed below the crushing roller 47 to separate the crushed glass fragments. When the first rotating shaft 46 rotates with the fourth rotating shaft 72, it can drive the crushing roller 47 to rotate quickly. The glass fed into the U-shaped feeding chamber 44 is crushed by the rotating cutting and impact of the crushing roller 47. The glass fragments that meet the requirements after crushing will fall down through the arc-shaped filter plate 48 and finally flow down through the falling channel 45, thereby realizing the crushing of the glass. The heated surface of the crushed glass is increased, so it can be heated and melted quickly, thereby improving the efficiency of melting the glass.

[0033] For details regarding the specific structure of the crushing mechanism 4, please refer to [link / reference]. Figure 4 and Figure 5 The system includes a U-shaped feeding shell 41 with a U-shaped cross-section. The bottom of the U-shaped feeding shell 41 has a transition structure 42 integrally formed with it. The bottom of the transition structure 42 has a sleeve structure 43 integrally formed with it. The interior of the U-shaped feeding shell 41 has a U-shaped feeding cavity 44 with an open top.

In order to achieve the crushing effect on the glass, multiple crushing fin structures arranged in a ring array are installed on the circumferential surface of the crushing roller 47.

[0034] To achieve the capabilities of melting glass and conveying glass raw materials, please refer to [link / reference needed]. Figure 1 , Figure 2 , Figure 3 and Figure 6A melting mechanism 5 needs to be installed, which contains a spiral conveying rod 56 that rotates with the rotor 3 of the drive motor 1 and can directionally drive glass fragments falling from the arc-shaped filter plate 48 during rotation. An induction coil 58 is spirally wound around the spiral conveying rod 56 and, when a variable frequency current is applied, heats the spiral conveying rod 56 under the action of eddy currents. When the high-frequency AC power is activated, the induction coil 58 generates electromagnetic induction. The eddy current heating effect generated by this electromagnetic induction causes an induced current to be generated within the spiral conveying rod 56 when it is placed in a changing magnetic field. This induced current forms a circulating current within the spiral conveying rod 56, causing it to heat up and reach a high temperature. At this time, the second rotating shaft 55 rotates with the third rotating shaft... After rotation of 71, the screw conveyor 56 will rotate in a specific direction. At this time, the broken glass that falls into the raw material conveying chamber 52 will move in a specific direction under the influence of the screw conveyor 56, thus moving towards the area of ​​the induction coil 58. When the broken glass comes into contact with the high-temperature screw conveyor 56, it will be heated and melted by the screw conveyor 56. Of course, by reducing the rotation speed of the screw conveyor 56, the melting time of the glass can be increased. The molten glass moves towards the conical feed chamber 64 under the action of the rotating screw conveyor 56. At the same time, the rotation speed of the screw conveyor 56 is kept stable, so the thrust it generates is relatively stable, thereby controlling the pressure and speed of the glass solution during extrusion, and thus maintaining a stable drawing pressure and speed of the glass solution during the drawing process.

[0035] For details regarding the specific structure of the melting mechanism 5, please refer to [link / reference]. Figure 6The system includes a horizontal hollow column 51 made of non-metallic material. A fixed base 2 is mounted on the circumferential surface of the horizontal hollow column 51 near the drive motor 1. The interior of the horizontal hollow column 51 has a raw material conveying cavity 52 with one open end.

A component that moves with the second rotating shaft is fixedly mounted at one end of the second rotating shaft 55 located inside the raw material conveying cavity 52. A rotating spiral conveyor rod 56, made of metal, rotates with the rotor 3 of the drive motor 1, causing the raw material conveying direction to face the opening end of the raw material conveying chamber 52. The circumferential surface of the spiral conveyor rod 56 is provided with an outer spiral structure. A heat insulation sleeve 57 is fixedly placed on the circumferential surface of the horizontal hollow column 51 located on one side of the sleeve structure 43. An induction coil 58 is embedded in the inside of the heat insulation sleeve 57. A terminal 59 is installed at each end of the induction coil 58. The terminal 59 is connected to a high-frequency AC power supply through a wire, and the high-frequency current generated by the high-frequency AC power supply can cause the induction coil 58 to generate a changing induced magnetic field.

[0036] To achieve the functions of drawing and cooling molten glass, please refer to [link / reference needed]. Figure 1 , Figure 2 , Figure 3 and Figure 7 A drawing mechanism 6 needs to be set up, which has a conical wire hole 66 located at the discharge port of the spiral conveyor 56, which can squeeze the glass molten glass into wires and discharge them downward under pressure; an annular vent hole 67 located on the circumferential surface of the conical wire hole 66; and a gas discharge hole 69 located on the circumferential side of the conical wire hole 66, which can simultaneously discharge the gas in the annular vent hole 67. First, the main air inlet 68 needs to be connected to the exhaust port of a blower and the blower is started. The molten glass in the molten state passes through the conical feed chamber 64 and the curved pipe hole 65 in sequence under the thrust, and is finally extruded through the conical wire hole 66. The extruded glass fiber filaments move downward. During this process, the gas generated by the blower will be sprayed around the glass fiber filaments through the gas discharge hole 69, thereby reducing the temperature of the glass fiber filaments and allowing the glass fiber filaments to cool and solidify rapidly.

[0037] For details regarding the specific structure of the wire drawing mechanism 6, please refer to [link / reference]. Figure 7This includes a secondary component docking port 61 that docks with the main component docking port 54. The discharge port of the secondary component docking port 61 is provided with a curved pipe 62 integrally formed with it. The curved pipe 62 has a cylindrical extension structure 63 integrally formed with it at its ground-facing end. The interior of the secondary component docking port 61 is provided with a conical feed chamber 64 that connects to the discharge port of the raw material conveying chamber 52. The interior of the curved pipe 62 is provided with a curved pipe hole 65 that connects to the discharge port of the conical feed chamber 64. The interior of the cylindrical extension structure 63 is provided with a connection between the space below it and the curved pipe. The tapered wire hole 66 at the discharge port of hole 65 needs to be a tapered structure with a top port diameter larger than its bottom port diameter in order to facilitate the flow and shaping of the glass solution. The bottom end of the tapered wire hole 66 extends downward to form a hole-like structure. The cylindrical extension structure 63 is provided with an annular vent hole 67 on its circumferential surface. The cylindrical extension structure 63 is provided with a main air inlet hole 68 that connects to the annular vent hole 67 on its circumferential side surface. The cylindrical extension structure 63 is provided with a plurality of gas discharge holes 69 located around the tapered wire hole 66 and connected to the annular vent hole 67 inside.

[0038] To achieve a tiered component drive effect and thus improve the effective utilization of drive motor 1, please refer to [link / reference needed]. Figure 1 , Figure 2 , Figure 3 and Figure 8 A central linkage mechanism 7 needs to be set up, which contains a main pulley 73 that rotates with the rotor 3 of the drive motor 1 and drives the screw conveyor 56 to rotate, and an auxiliary pulley 74 that rotates with the main pulley 73 via a belt 77 and drives the crushing roller 47 to rotate. When the drive motor 1 is started, the main pulley 73 drives the screw conveyor 56 to rotate, and the auxiliary pulley 74 drives the crushing roller 47 to rotate, thereby achieving the effect of graded component drive and improving the effective utilization rate of the drive motor 1.

[0039] For details regarding the structure of the central linkage mechanism 7, please refer to [link / reference]. Figure 8The system includes a third rotating shaft 71 connected to a second rotating shaft 55 via a coupling, and a fourth rotating shaft 72 connected to a first rotating shaft 46 via a coupling. The third rotating shaft 71 has a main pulley 73 integrally formed with it at its end. One rotating end of the main pulley 73 has a concave shaft fixing groove 75. The rotor 3 of the drive motor 1 is fixedly installed inside the shaft fixing groove 75 on the main pulley 73. The fourth rotating shaft 72 has a secondary pulley 74 integrally formed with it at its end. To achieve different driving speeds depending on the actual situation, the structural radius of the main pulley 73 needs to be larger than that of the secondary pulley 74. Both the main pulley 73 and the secondary pulley 74 have belt grooves 76 on their circumferential surfaces, and belts 77 are held in the belt grooves 76 of both the main pulley 73 and the secondary pulley 74.

[0040] The specific working principle of this invention is as follows: when the high-frequency AC power supply is turned on, the induction coil 58 generates electromagnetic induction. The eddy current heating effect generated by the electromagnetic induction causes an induced current to be generated in the spiral conveying rod 56 when it is placed in a changing magnetic field. This induced current forms a circulating current in the spiral conveying rod 56, causing the spiral conveying rod 56 to heat up and reach a high temperature.

[0041] Start the drive motor 1, the main pulley 73 drives the screw conveyor 56 to rotate, and the auxiliary pulley 74 drives the crushing roller 47 to rotate. Then the glass is put into the U-shaped feeding chamber 44. Under the rotation, cutting and impact of the crushing roller 47, the glass is broken. After being broken, the glass fragments that meet the requirements will fall down through the arc-shaped filter plate 48 and finally flow down through the falling channel 45.

[0042] The broken glass that falls into the raw material conveying chamber 52 will undergo directional movement under the influence of the spiral conveying rod 56, thus moving towards the area of ​​the induction coil 58. When the broken glass comes into contact with the high-temperature spiral conveying rod 56, it will be heated and melted by the spiral conveying rod 56. Of course, by reducing the rotation speed of the spiral conveying rod 56, the melting time of the glass can be increased. The molten glass moves towards the conical feed chamber 64 under the action of the rotating spiral conveying rod 56.

[0043] The blower is started, and the molten glass passes through the conical feed chamber 64 and the curved pipe hole 65 in sequence under the thrust, and is finally extruded through the conical wire hole 66. The extruded glass fiber filaments move downward. During this process, the gas generated by the blower is sprayed around the glass fiber filaments through the gas discharge hole 69, thereby reducing the temperature of the glass fiber filaments and allowing them to cool and solidify rapidly.
