Abstract
Description
Technical Field
[0001] This utility model relates to the field of glass fiber drawing technology, specifically to a glass fiber drawing device. Background Technology
[0002] Glass fiber is a high-performance inorganic fiber material made from glass. Its main components include silicon dioxide (SiO2), aluminum oxide (Al2O3), calcium oxide (CaO), etc. After being melted at high temperature, it is drawn into fibers at high speed through a platinum-rhodium alloy spinneret. The diameter of a single filament is usually between 5 and 25 micrometers. Chinese Patent Publication No. CN 218931973 U discloses a glass fiber drawing device, which includes a support frame, a melting furnace slidably mounted on the top of the support frame, a discharge pipe mounted on the bottom of the melting furnace, a support plate fixed inside the support frame, and a drawing spinneret that is driven to move by a first motor slidably mounted on the top of the support plate. The bottom end of the discharge pipe passes through the inside of the support frame and extends into the drawing spinneret.
[0003] In the above technical solution, a glass fiber drawing device, although it can connect clamping plates on opposite sides of two sets of rotating plates through spring telescopic tubes and limit the drawing rollers through the inserts on the two sets of clamping plates, the centrifugal force of the rotating plates will cause uneven distribution of the pre-tightening force of the spring telescopic tubes when the rotating plates are rotating. This may cause periodic fluctuations in the clamping force of the clamping plates on the rollers, affecting the drawing and winding. Furthermore, the spring resonance at high speed will amplify the pressure imbalance, and in severe cases, it will cause the inserts to detach from the contact surface of the rollers.
[0004] Therefore, a glass fiber drawing device is proposed. Utility Model Content
[0005] The purpose of this utility model is to provide a glass fiber drawing device in order to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:
[0007] A glass fiber drawing device includes a fixed frame and a drawing roller. A cross shaft is provided on both sides of the drawing roller, and a hexagonal prism is provided on the surface of each cross shaft. Two support rods are symmetrically arranged on the top of the fixed frame, and the cross shafts are rotatably mounted on the support rods. An adjustment mechanism for adjusting the position and distance is provided on the fixed frame. A rotating mechanism for driving the drawing roller to rotate is provided on the top of the fixed frame, and the rotating mechanism is mounted on the adjustment mechanism. The hexagonal prisms are mounted on the rotating mechanism.
[0008] Furthermore, the adjustment mechanism includes a bidirectional screw, which is rotatably mounted inside the fixed frame. Two adjustment plates are threadedly mounted on the outer wall of the bidirectional screw, and the adjustment plates are slidably mounted on the fixed frame. A fixed plate is fixedly mounted on the top of each of the two adjustment plates. A motor is fixedly mounted on the surface of the fixed frame, and the bidirectional screw is fixedly mounted on the output end of the motor.
[0009] Furthermore, the rotating mechanism includes two limiting rings, which are rotatably mounted on two adjusting plates, and a synchronous wheel is fixedly mounted on the surface of the two limiting rings.
[0010] Furthermore, two mounting plates are fixedly installed on the top of the fixed frame, and a non-circular shaft is rotatably installed between the two mounting plates. Non-circular holes are penetrating the surfaces of the two synchronous pulleys, and the non-circular shaft is slidably installed on the inner wall of the non-circular hole. Circular holes are penetrating the surfaces of the two adjusting plates, and the diameter of the circular holes is larger than the shaft diameter of the non-circular shaft. The non-circular shaft is located inside the circular holes. A second motor is fixedly installed on the surface of one of the mounting plates, and the non-circular shaft is fixedly installed at the output end of the second motor.
[0011] Furthermore, a limiting cylinder is rotatably mounted on both of the fixed plates, and a second synchronous wheel is fixedly mounted on the surface of each of the two limiting cylinders. A synchronous belt is meshed on the outer wall of each of the two first synchronous wheels and the second synchronous wheel.
[0012] Furthermore, a fixing post is fixedly installed on the surface of each of the two synchronous pulleys, and a hexagonal groove is opened on the surface of each of the two fixing posts, and the hexagonal post is slidably installed on the inner wall of the hexagonal groove.
[0013] The beneficial effects of this utility model are as follows:
[0014] This invention, through the arrangement of a bidirectional screw, a special-shaped shaft, and hexagonal columns, allows for easy operation. In use, the two cross shafts on the drawing roller are placed on two support rods for support and positioning. Starting motor one drives the bidirectional screw to rotate, causing the two adjusting plates to move closer together. This moves the two fixed plates accordingly, and the two synchronous pulleys (both first and second) also move closer together. When the two synchronous pulleys (second) move closer together, the two hexagonal columns are inserted into the hexagonal grooves, thus limiting the drawing roller's position. Starting motor two drives the special-shaped shaft to rotate, which in turn drives the two synchronous pulleys (first). With the cooperation of two synchronous belts, the two synchronous pulleys (second) rotate, causing the fixed columns, cross shafts, hexagonal columns, and drawing roller to rotate, drawing and winding the glass fiber. Conversely, disassembly is possible, facilitating the installation and replacement of the drawing roller. The drawing roller is stably installed and will not shift or wobble due to rotation. The operation is simple and highly practical. Attached Figure Description

[0024] like Figure 1-3 As shown, a glass fiber drawing device includes a fixed frame 1 and a drawing roller 3. A cross shaft 4 is provided on both sides of the drawing roller 3, and a hexagonal prism 5 is provided on the surface of each cross shaft 4. Two support rods 7 are symmetrically arranged on the top of the fixed frame 1, and the cross shafts 4 are rotatably mounted on the support rods 7. An adjustment mechanism 2 for adjusting the position distance is provided on the fixed frame 1. A rotation mechanism 6 for driving the drawing roller 3 to rotate is provided on the top of the fixed frame 1, and the rotation mechanism 6 is mounted on the adjustment mechanism 2. The hexagonal prisms 5 are mounted on the rotation mechanism 6. In this embodiment, during use, the two cross shafts 4 on the drawing roller 3 are rotated... The shaft 4 is placed on two support rods 7 for support and positioning. Then, the connecting part of the rotating mechanism 6 is moved by the adjusting mechanism 2 so that it fits onto the two hexagonal columns 5, thus limiting the drawing roller 3. Starting the rotating mechanism 6 can drive the cross shaft 4, hexagonal columns 5 and drawing roller 3 to rotate, drawing and winding the glass fiber. Conversely, by moving the connecting part of the rotating mechanism 6 through the hexagonal columns 5, it disengages from the two hexagonal columns 5, allowing the drawing roller 3 to be removed and replaced. This facilitates the installation and replacement of the drawing roller 3, and the drawing roller 3 is installed stably without shifting or shaking due to rotation. The operation is simple and highly practical.
[0025] like Figure 1-2 As shown, the adjustment mechanism 2 includes a bidirectional screw 201, which is rotatably mounted inside the fixed frame 1. Two adjusting plates 202 are threadedly mounted on the outer wall of the bidirectional screw 201, and the adjusting plates 202 are slidably mounted on the fixed frame 1. A fixed plate 203 is fixedly mounted on the top of each of the two adjusting plates 202. A motor 204 is fixedly mounted on the surface of the fixed frame 1, and the bidirectional screw 201 is fixedly mounted on the output end of the motor 204. In this embodiment, when the motor 204 is started, the bidirectional screw 201 is driven to rotate, and the two adjusting plates 202 move closer to each other or further away from each other, while the two fixed plates 203 move accordingly, thereby adjusting the distance between the two adjusting plates 202.
[0026] like Figure 1-3As shown, the rotating mechanism 6 includes two limiting rings 603, which are rotatably mounted on two adjusting plates 202 respectively. Synchronous wheels 604 are fixedly mounted on the surfaces of the two limiting rings 603. In this embodiment, when the two adjusting plates 202 move closer to each other or further away from each other, the two synchronous wheels 604 move accordingly.
[0027] like Figure 1-3 As shown, two mounting plates 601 are fixedly installed on the top of the fixed frame 1. A non-circular shaft 602 is rotatably mounted between the two mounting plates 601. Non-circular holes are penetrating the surfaces of the two synchronous pulleys 604, and the non-circular shaft 602 is slidably mounted on the inner wall of the non-circular hole. A circular hole is penetrating the surfaces of the two adjusting plates 202, and the diameter of the circular hole is larger than the shaft diameter of the non-circular shaft 602. The non-circular shaft 602 is located inside the circular hole. A motor 609 is fixedly mounted on the surface of one of the mounting plates 601, and the non-circular shaft 602 is fixedly mounted at the output end of the motor 609. In this embodiment, when the motor 609 is started, it drives the non-circular shaft 602 to rotate. Since the diameter of the circular hole is larger than the shaft diameter of the non-circular shaft 602, it will not affect the normal rotation of the non-circular shaft 602, driving the two synchronous pulleys 604 to rotate, and the two limiting rings 603 rotate accordingly.
[0028] like Figure 2-3 As shown, a limiting cylinder 605 is rotatably mounted on each of the two fixed plates 203. A second synchronous wheel 606 is fixedly mounted on the surface of each of the two limiting cylinders 605. A synchronous belt 607 is meshed on the outer wall of each of the two first synchronous wheels 604 and the second synchronous wheel 606. In this embodiment, when the two fixed plates 203 move closer to or further away from each other, the two second synchronous wheels 606 move accordingly. When the two first synchronous wheels 604 rotate, the two second synchronous wheels 606 rotate accordingly with the cooperation of the two synchronous belts 607.
[0029] like Figure 3 As shown, a fixing post 608 is fixedly installed on the surface of each of the two synchronous pulleys 606. A hexagonal groove is opened on the surface of each of the two fixing posts 608, and the hexagonal post 5 is slidably installed on the inner wall of the hexagonal groove. In this embodiment, when the two synchronous pulleys 606 move closer to each other, the two hexagonal posts 5 will be inserted into the inside of the hexagonal groove to complete the limiting installation. When the two synchronous pulleys 606 rotate, the two hexagonal posts 5, the two cross shafts 4 and the wire drawing roller 3 rotate.
[0030] In summary, during use, the two cross shafts 4 on the drawing roller 3 are placed on the two support rods 7 for support and positioning. Then, the connecting parts of the rotating mechanism 6 are moved by the adjusting mechanism 2 to fit onto the two hexagonal columns 5, thus limiting the drawing roller 3. Starting the rotating mechanism 6 rotates the cross shafts 4, hexagonal columns 5, and drawing roller 3 to draw and wind the glass fiber. Conversely, by moving the connecting parts of the rotating mechanism 6 through the hexagonal columns 5, disengaging them from the two hexagonal columns 5, the drawing roller 3 can be removed for replacement. This facilitates the installation and replacement of the drawing roller 3, and the drawing roller 3 is stably installed without shifting or shaking due to rotation. The operation is simple and highly practical. Starting the motor 204 drives the bidirectional screw 201 to rotate, causing the two adjusting plates 202 to move closer or further apart, while the two fixed plates 203 move accordingly, thus controlling the two... The distance between the two adjusting plates 202 is adjusted. When the two adjusting plates 202 move closer to each other or further away from each other, the two synchronous pulleys 604 move accordingly, starting the motor 609 and driving the irregular shaft 602 to rotate. Since the diameter of the round hole is larger than the shaft diameter of the irregular shaft 602, it will not affect the normal rotation of the irregular shaft 602, driving the two synchronous pulleys 604 to rotate. The two limiting rings 603 rotate accordingly. When the two fixed plates 203 move closer to each other or further away from each other, the two synchronous pulleys 606 move accordingly. When the two synchronous pulleys 604 rotate, the two synchronous pulleys 606 rotate accordingly with the cooperation of the two synchronous belts 607. When the two synchronous pulleys 606 move closer to each other, the two hexagonal posts 5 will be inserted into the hexagonal slots to complete the limiting installation. When the two synchronous pulleys 606 rotate, the two hexagonal posts 5, the two cross shafts 4, and the wire drawing roller 3 rotate.
