Description

Technical Field

[0001] This utility model relates to the field of glass fiber preparation technology, and in particular to a feeding device for glass fiber preparation. Background Technology

[0002] In the glass fiber manufacturing process, glass rods are a key raw material, and the stability of their feeding process directly affects the quality and efficiency of subsequent drawing processes. However, existing feeding devices generally suffer from problems such as unreasonable structural design, insufficient guiding accuracy, and poor conveying stability. Traditional devices often use fixed guide holes or simple roller structures to guide the glass rods, lacking effective control over the dynamic behavior of the glass rods during vertical conveying. When the glass rod is long, its own weight can easily cause vibration in the middle, which not only exacerbates friction with the inner wall of the guide hole, causing surface damage or even breakage, but may also cause jamming or conveying interruption due to positional deviation, seriously affecting continuous production.

[0003] Meanwhile, existing guide rollers are typically rigid and fixed, unable to adaptively adjust to minute changes in glass rod diameter or thermal expansion effects. This makes it difficult to maintain a constant clamping force, leading to slippage or excessive compression, further reducing conveying reliability and material utilization. Furthermore, most existing devices lack an effective power coordination mechanism, resulting in a lack of synchronous drive between guide stages. This causes uneven force distribution on the glass rod during multi-stage conveying, generating cumulative errors and ultimately affecting the consistency of fiber forming. These shortcomings not only increase scrap rates and energy consumption but also hinder the construction of high-efficiency, high-quality glass fiber production lines.

[0004] Therefore, there is an urgent need for a new technology that can effectively suppress glass rod vibration, achieve adaptive clamping, and ensure continuous and stable feeding, so as to overcome the shortcomings of existing devices in terms of structural adaptability, operational stability, and material economy, and meet the comprehensive requirements of modern glass fiber manufacturing for high precision, high reliability, and low cost control. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, this utility model discloses a feeding device for glass fiber preparation.

[0006] To achieve the above-mentioned objectives, the present invention adopts the following technical solution:

[0007] A feeding device for glass fiber preparation, comprising:

[0008] Fixture;

[0009] The guide components are multiple ones spaced apart from top to bottom along the fixed frame;

[0010] A drive unit, mounted on one side of the fixed frame, is used to provide power to the guide assembly;

[0011] The guiding component includes:

[0012] The guide plate has multiple guide holes spaced apart along its length on both sides of its surface.

[0013] The guide roller assembly consists of two sets, located on either side of the bottom of the guide plate; the guide roller assembly is used to drive the glass rod that passes through the guide hole in the guide plate;

[0014] The guide roller assembly includes:

[0015] The active roller has both ends rotatably connected to the fixed frame, and one end of the active roller is connected to the drive device for transmission.

[0016] The driven roller is located on one side of the driving roller, and the fixing frame has strip-shaped holes corresponding to the driven roller; the driven roller can float horizontally along the strip-shaped holes;

[0017] The pusher device consists of two parts, which are installed at both ends of the driven roller. It is used to push the driven roller closer to the driving roller and press the glass rod onto the driving roller.

[0018] Preferably, the jacking device includes:

[0019] The mounting base is installed on the mounting bracket;

[0020] The T-shaped floating seat is located on one side of the fixed seat, and the driven roller is rotatably connected to the T-shaped floating seat.

[0021] The guide columns are two spaced apart. One end of the guide column is fixedly connected to the fixed base, and the other end moves through the T-shaped floating base.

[0022] There are two springs, which are respectively sleeved on the rod between the guide post and the T-shaped floating seat.

[0023] Preferably, the two drive rollers of the guide roller assembly are synchronously driven by two corresponding meshing gears.

[0024] Preferably, the driving device is a motor, which is connected to the drive roller of one of the guide roller groups; two adjacent drive rollers are connected synchronously through a synchronous belt drive mechanism or a chain drive mechanism.

[0025] Preferably, the active roller has an annular limiting groove at the position corresponding to the glass rod.

[0026] Preferably, protective covers are installed on both sides of the fixing frame.

[0027] By adopting the technical solution described above, this utility model has the following beneficial effects:

[0028] (1) This utility model, by arranging multiple guide components at intervals from top to bottom within the fixed frame, enables the glass rod to be continuously and stably guided and conveyed during the feeding process, effectively avoiding the shaking problem caused by the excessive length of the glass rod and improving the overall stability of operation. The guide component adopts a structure combining a guide plate and a guide roller group. The guide holes on the guide plate perform initial positioning of the glass rod, while the guide roller group drives and conveys the glass rod through the clamping action of the active roller and the driven roller. This not only reduces the frictional vibration between the glass rod and the guide hole, but also significantly reduces material loss and improves material utilization and production efficiency.

[0029] (2) In the guide roller assembly of this utility model, the driven roller is installed on the fixed frame through the strip hole and is pushed horizontally by the jacking device, so that it can float towards the driving roller and clamp the glass rod. This structure achieves reliable clamping of the glass rod and has good adaptability. Furthermore, the jacking device adopts an elastic jacking structure composed of a fixed seat, a T-shaped floating seat, a guide column and a spring. The spring continuously provides clamping force, so that the driven roller can automatically adjust the clamping position according to the diameter of the glass rod. While ensuring clamping stability, it avoids damage to the surface of the glass rod due to excessive clamping force, and improves the compatibility and safety of the equipment for glass rods of different specifications.

[0030] (3) The active rollers of the guide roller group of this utility model achieve synchronous transmission through meshing gears, and are connected by a synchronous belt or chain drive mechanism between adjacent active rollers, so that the entire device only needs one drive motor to realize the synchronous operation of all guide roller groups. This transmission structure simplifies the layout of the power system, reduces energy consumption and maintenance costs, and ensures that the glass rod maintains a consistent conveying speed and tension throughout the entire feeding path, significantly improving the coordination and conveying accuracy of the equipment operation.

[0031] (4) The active roller of this invention is provided with an annular limiting groove. During the conveying process, the outer periphery of the glass rod is embedded in the limiting groove, thereby obtaining further constraint in the radial direction and effectively preventing the glass rod from shifting or jumping during high-speed conveying. This structure enhances the positioning accuracy and stability of the glass rod during the conveying process, helps to improve the quality consistency of the subsequent glass fiber drawing process, and further ensures the reliability and yield of the entire preparation process.

[0040] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0041] Example 1:

[0042] Combined with appendix Figures 1-3A glass fiber preparation feeding device includes a fixed frame 1, guiding components, and a driving device 6. The fixed frame 1 is vertically arranged and has an overall frame structure, used to support and install the other components. Within the installation space of the fixed frame 1, multiple guiding components are spaced apart from top to bottom, arranged sequentially along the vertical direction to meet the continuous guiding and conveying requirements of the glass rod during the feeding process. The driving device 6 is installed on one side of the fixed frame 1, providing power to the guiding components to ensure that the glass rod is stably and continuously conveyed as it passes through the guiding components.

[0043] Specifically, the guiding assembly includes a guide plate 2 and a set of guide rollers. The guide plate 2 is a flat plate with multiple guide holes spaced apart along its length on both sides of its surface; the glass rod used to prepare the glass fiber can move through these guide holes, thereby achieving initial positioning and guidance of the glass rod. A set of guide rollers is installed on both sides of the bottom of the guide plate 2; the guide rollers are used to clamp and drive the glass rod passing through the guide holes of the guide plate 2, causing it to continue to be conveyed downwards.

[0044] The guide roller assembly includes a driving roller 3 and a driven roller 4. Both ends of the driving roller 3 are rotatably connected to the fixed frame 1, and one end of the driving roller 3 is drive-connected to the driving device 6, which drives its rotation. The driven roller 4 is located on one side of the driving roller 3, and the fixed frame 1 has a strip-shaped hole corresponding to the position of the driven roller 4. Both ends of the driven roller 4 pass through this strip-shaped hole and can float horizontally along the hole. Pushing devices 5 are installed at both ends of the driven roller 4, applying a horizontal pushing force to the driven roller 4, causing it to move towards the driving roller 3, thereby clamping the glass rod between the driving roller 3 and the driven roller 4. When the glass rod passes through the guide hole of the guide plate 2, it is clamped by the driving roller 3 and the driven roller 4 of the corresponding guide roller assembly. The driving roller 3 rotates under the drive of the driving device 6, thus driving the glass rod downwards. This structure effectively prevents the glass rod from shaking during transmission due to its excessive length. It also suppresses frictional vibration between the glass rod and the guide hole, thereby improving the overall stability of the equipment, reducing material loss, increasing material utilization, and lowering production costs.

[0045] Example 2:

[0046] Combined with appendix Figures 3-4A feeding device for glass fiber preparation differs from Embodiment 1 in that the specific structure of the pushing device 5 is optimized based on Embodiment 1. The pushing device 5 includes a fixed base 5-1, a T-shaped floating seat 5-2, guide columns 5-3, and a spring 5-4. The fixed base 5-1 is bolted to a fixed frame 1, serving as the supporting foundation for the pushing device 5. The T-shaped floating seat 5-2 is located on one side of the fixed base 5-1, and its T-shaped structure facilitates stable horizontal movement. The end of the driven roller 4 is rotatably connected to the T-shaped floating seat 5-2, allowing the driven roller 4 to move together with the T-shaped floating seat 5-2. Two guide columns 5-3 are spaced apart on the fixed base 5-1. One end of each guide column 5-3 is tightly connected to the fixed base 5-1, and the other end movably passes through the T-shaped floating seat 5-2, allowing the T-shaped floating seat 5-2 to slide smoothly horizontally along the guide columns 5-3. A spring 5-4 is movably sleeved on the rod of the guide post 5-3, located between the fixed seat 5-1 and the T-shaped floating seat 5-2. One end of the spring 5-4 abuts against the fixed seat 5-1, and the other end abuts against the T-shaped floating seat 5-2. The elastic force of the spring 5-4 continuously pushes the T-shaped floating seat 5-2, causing it to move along the guide post 5-3 towards the driving roller 3, thereby driving the driven roller 4 to approach the driving roller 3 and stably clamping the glass rod between the two. This structure not only achieves reliable clamping of the glass rod but also has a certain degree of self-adjustment capability, which can adapt to glass rods of different diameters, while avoiding damage to the surface of the glass rod due to excessive clamping force.

[0047] Example 3:

[0048] Combined with appendix Figure 1 and 3 A feeding device for glass fiber preparation, based on Embodiment 1 or Embodiment 2, further optimizes the transmission structure of the guide roller group. The two active rollers 3 of the guide roller group are synchronously connected through two meshing gears. This structure allows the drive device 6 to drive only one active roller 3, which in turn drives the other active roller 3 to rotate synchronously through gear meshing, thereby ensuring that the glass rods on both sides can be uniformly conveyed.

[0049] Furthermore, the drive device 6 is a motor, whose output shaft is connected to the drive roller 3 of one of the guide roller groups. Two adjacent drive rollers 3 are synchronously connected via a synchronous belt drive mechanism or a chain drive mechanism. In other words, the entire feeding device only needs one motor as the drive source to transmit power sequentially to the drive rollers 3 of all guide roller groups via a synchronous belt or chain. (See attached diagram) Figure 3As shown, the motor is connected to the drive roller 3 of all guide roller groups through a continuous synchronous belt or chain, so that all guide roller groups on the fixed frame 1 can move synchronously, ensuring that the glass rod maintains a consistent conveying speed and tension throughout the entire feeding path, and further improving the coordination and stability of the equipment operation.

[0050] Furthermore, protective covers 7 are installed on both sides of the fixing frame 1; the protective covers 7 protect the transmission mechanism of the guide roller assembly and prevent foreign objects from entering.

[0051] Example 4:

[0052] Combined with appendix Figure 5 A feeding device for glass fiber preparation is disclosed, which improves the structure of the active roller 3 based on any one of the embodiments in Examples 1 to 3. The roller surface of the active roller 3 is provided with an annular limiting groove at a position corresponding to the glass rod conveying path. When the glass rod passes through the guide hole of the guide plate 2, its outer circumference can be embedded in the annular limiting groove, thereby being further limited by the active roller 3 in the radial direction. This structure can effectively prevent the glass rod from shifting laterally or jumping during conveying, further suppressing its vibration during high-speed conveying, and improving conveying accuracy and stability.

[0053] The parts of this utility model not described in detail are prior art. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that this utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be regarded as exemplary and non-limiting in all respects, and are intended to include all changes that fall within the meaning and scope of equivalents within this utility model.
