Abstract
Description
Technical Field
[0001] The invention relates to the technical field of glass fiber yarn guides, in particular to a glass fiber yarn guide device. Background Art
[0002] Glass fiber is an inorganic non-metallic fiber material made from glass as raw material. It is formed into filaments with a diameter of microns through high-temperature melting and drawing processes. Its diameter is usually 5-25 microns, and a single filament can be several thousand meters long. It has the characteristics of high strength, corrosion resistance, and good insulation. It is widely used in composite materials, construction, electronics and other fields. The main raw materials of glass fiber include silica (quartz sand), limestone, soda ash and other minerals. After being melted into liquid glass at high temperature (about 1400°C), it is drawn into continuous fibers at high speed with the help of a platinum-rhodium alloy bushing. A coupling agent (such as silane) needs to be applied during the drawing process to enhance the bonding strength between the fiber and the matrix such as the resin. Depending on the application, the fiber diameter can be adjusted by the bushing aperture and the drawing speed to form yarns, fabrics or chopped fibers of different specifications.
[0003] Glass fiber yarn guides are key components of textile machinery, primarily used for guiding and tensioning glass fiber yarns and for yarn replacement during continuous production. Traditional yarn guides typically consist of a guide wheel, a tension adjustment mechanism, and a yarn roller support structure. Their core function is to ensure smooth yarn transport during processing, preventing breakage and entanglement. However, when yarn runs out, traditional systems require manual intervention for yarn replacement, resulting in low efficiency, prolonged downtime, and high labor costs.
[0004] In the existing technology, some automated yarn guide devices use robotic arms or simple cylinders to replace yarn rollers, but there are still the following shortcomings:
[0005] First, yarn change precision is low, relying on manual positioning or simple mechanical drive. This can easily cause deviation when the new and old yarns are joined, leading to connection failure or yarn damage. Furthermore, connection reliability is poor, as yarns are connected using gluing or mechanical clamping, which can easily break due to temperature changes or tension fluctuations.
[0006] The above defects seriously restrict the production efficiency and product quality of glass fiber, and a high-precision and high-reliability automatic yarn changing solution is urgently needed. Summary of the Invention

[0045] The first cylinder 313 pushes the rack 312 to move linearly, driving the gear 311 to rotate, and then driving the rotating tube 321 and the yarn roller placement member 32 to rotate, thereby switching the positions of the new and old yarn rollers.

[0050] Reference Figure 6 The yarn splicing auxiliary component 34 also includes a guide rod 345, and the bottom outer wall of the guide rod 345 is welded to the top outer wall of the U-shaped frame 343. A linear bearing is fixedly connected to the inner wall of the connecting plate 341, and the guide rod 345 is slidably connected to the inner wall of the linear bearing.
[0051] The second cylinder 342 of the yarn splicing auxiliary assembly 34 is activated, pushing the U-shaped frame 343 downward vertically along the guide rod 345. The groove design of the yarn hook 344 captures the ends of the new and old yarns. The tight fit between the guide rod 345 and the linear bearing ensures that the yarn hook 344 does not deviate laterally during the downward pressure.
[0052] Example 4, refer to Figure 3 The spinning mechanism 4 includes a column 41, a top plate 42, a rotary downward pressure cylinder 43 and a downward pressure plate 44, wherein the column 41 is arranged inside the rotating tube 321, and the column 41 is welded to the top outer wall of the base 1, the top plate 42 is welded to the top outer wall of the column 41, the rotary downward pressure cylinder 43 is fixedly connected to the top outer wall of the top plate 42 by screws, and the downward pressure plate 44 is installed on the piston rod of the rotary downward pressure cylinder 43.

[0058] Reference Figure 7 The outer wall of the top of the support frame 2 is rotatably connected to an adjacently distributed yarn guide wheel 7.
[0059] Working principle:
[0060] When the glass fiber yarn is about to run out, the photoelectric sensor 5 monitors the remaining amount of old yarn in real time and sends a signal to the control system to trigger the automatic yarn replacement process. The specific working principle is as follows:
[0061] Yarn roller positioning and switching:
[0062] The first cylinder 313 pushes the rack 312 into linear motion, causing the gear 311 to rotate precisely. This in turn drives the rotating tube 321 and the yarn roller placement member 32 to rotate 180°, quickly aligning the spare yarn roller with the old yarn. During this rotation, the rotating downward pressure cylinder 43 of the spinning mechanism 4 drives the downward pressure plate 44 to apply constant pressure to the yarn roller, preventing the yarn from loosening or shifting.
[0063] Pulling of new and old yarn ends:
[0064] The second cylinder 342 of the yarn splicing auxiliary assembly 34 is activated, pushing the U-shaped frame 343 to move vertically downward along the guide rod 345. The yarn hanging head 344 accurately captures the ends of the new and old yarns and pulls them to the hot pressing area of the yarn splicer 6. The cooperation between the guide rod 345 and the linear bearing ensures the stability of the vertical movement and prevents lateral deviation.
[0065] Hot pressing welding process:
[0066] Heating Principle and Platen Structure: The yarn hot platen 63 incorporates a high-precision resistance heating element (e.g., nickel-chromium alloy resistance wire) that generates heat through the Joule effect when powered. A high-temperature-resistant ceramic coating ensures even heat distribution, keeping the temperature of the yarn hot platen 63 stable within the melting temperature range of the glass fiber.
[0067] Welding Operation: A double-ended cylinder 61 drives a Z-shaped plate 62, causing two opposing yarn hot presses 63 to close synchronously, clamping the ends of the new and old yarns in between. Once the hot presses close, the high temperature melts the surface of the glass fiber. After heating for 1-2 seconds, the yarn hot presses 63 separate, allowing the yarn joint to cool and solidify naturally, forming a high-strength weld.
[0068] Temperature and time control:
[0069] The control system presets heating parameters based on yarn diameter and material, and provides real-time temperature feedback via thermocouples to prevent overheating that could cause yarn embrittlement or melting. The yarn guide ring 65 guides the yarn during the welding process, ensuring precise connection.
[0070] Continuous production resumption:
[0071] After the welding is completed, the yarn guide wheel 7 guides the new yarn into the processing path, the old yarn roller is quickly removed through the sliding design of the insertion rod 323, the yarn changing mechanism 3 is reset, and the equipment resumes continuous production.
