Description

Technical Field

[0001] This utility model belongs to the field of glass fiber processing technology, and specifically relates to a glass fiber sizing device. Background Technology

[0002] Glass fiber is a high-performance inorganic non-metallic material with many varieties. Its advantages include excellent insulation, strong heat resistance, good corrosion resistance, and high mechanical strength. It is produced from seven minerals—pyrophyllite, quartz sand, limestone, dolomite, borocalcite, and boromagnesia—through high-temperature melting, drawing, winding, and weaving processes. During the production of glass fiber, the fiber filaments need to be sized to ensure they have sufficient strength to meet product quality requirements.

[0003] In existing glass fiber sizing mechanisms, passing glass fiber through sizing material is a common method. However, sizing by carrying out the sizing material can easily lead to uneven sizing. On the other hand, using a scraper to spread the sizing material has low adaptability to glass fibers of different thicknesses. Utility Model Content

[0004] The purpose of this invention is to provide a glass fiber sizing device with a simple structure and high working efficiency. It can evenly coat the sizing agent onto the surface of glass fiber and can adapt to glass fiber of different thicknesses and different coating thicknesses. It is easy to adjust, highly practical, and suitable for widespread application.

[0005] This utility model provides the following technical solution: a glass fiber sizing device, including a sizing cylinder, a strip-shaped opening seat fixed on the side wall of the sizing cylinder, the opening seat being strip-shaped and extending to both ends of the sizing cylinder, a central roller being mounted inside the sizing cylinder via a rotating shaft, both ends of the sizing cylinder being fixed on a support, an external frame extending outward from the opening seat of the sizing cylinder being fixed thereon, and a guide roller being mounted on the top of the external frame via a rotating shaft;

[0006] The opening seat has four symmetrical sliding seats on both sides. A scraper is fixed between two horizontal sliding seats. The scraper fits tightly with the opening of the opening seat. There is a gap between the upper and lower scrapers. The glass fiber on the guide roller passes through the center of the gap.

[0007] The opening seat is fixedly mounted on the outside of the sliding seat with a limiting plate. A lifting plate is fixedly mounted on the two sliding seats on one side between the limiting plates. A threaded column is rotatably mounted on the limiting plate. The threaded column passes through the threaded hole on the lifting plate. The two pushing threads on the threaded column are symmetrical.

[0008] Preferably, the sliding seat is fitted to the side wall of the open seat via a slide rail, and the threaded column is fixedly provided with limiting rings on the upper and lower sides of the limiting plate.

[0009] Preferably, a knob is fixedly provided on the top of the threaded column, and a sliding column is provided on the side of the opening seat away from the threaded column, and the sliding seat on this side is slidably connected to the sliding column.

[0010] Preferably, the sizing cylinder is provided with an upwardly extending groove below the opening seat, and when the glass fiber extends from below the central roller to above the guide roller, its inclination angle is such that it only contacts the sizing material in the sizing cylinder.

[0011] Preferably, the distance from the guide roller to the opening seat is such that the slurry on the glass fiber has solidified when it reaches the guide roller, and a drying mechanism is mounted on the external frame.

[0012] The beneficial effects of this utility model are: simple structure, high working efficiency, can evenly coat the slurry onto the surface of glass fiber, and can adapt to glass fiber of different thicknesses and different coating thicknesses, which is easy to adjust and highly practical, as detailed below:

[0013] (1) The present invention is equipped with a guide roller. When sizing glass fiber, slurry that is submerged in the extension groove is injected into the sizing cylinder. The glass fiber is inserted from the upper side of the opening of the opening seat, passes around the center roller, passes through the gap between the two scrapers, passes over the top of the guide roller, and is connected to the winding mechanism. At this time, the winding mechanism operates, pulling the glass fiber through the slurry below. The excess slurry is scraped off when it passes the scraper. The glass fiber pulled out of the sizing cylinder is dried on the outside and wound up after passing the guide roller, thereby achieving uniform sizing of the glass fiber.

[0014] (2) This utility model is equipped with a sliding seat. When sizing glass fibers of different thicknesses, by rotating the knob, the threaded column will move away or approach at the same speed because the two sections of its pushing threads are in opposite directions. This will drive the scraper to move. The number of rotations of the knob represents the movement distance. By changing the distance between the two scrapers, different thicknesses of sizing can be applied to glass fibers of different thicknesses. The glass fibers are stretched straight by the lower part of the center roller and the upper part of the guide roller. The inclination of the fiber satisfies the requirement of passing through the center of the scraper spacing, so that the sizing thickness on the upper and lower sides is the same.

[0023] The structural features of this utility model will now be described in detail with reference to the accompanying drawings.

[0024] See Figures 1-2A glass fiber sizing device includes a sizing cylinder 1. A strip-shaped opening seat 2 is fixedly mounted on the side wall of the sizing cylinder 1, extending to both ends of the sizing cylinder 1. A central roller 3 is mounted inside the sizing cylinder 1 via a rotating shaft. Glass fibers 6 enter through openings in the opening seat 2, coil around the central roller 3, and exit. Both ends of the sizing cylinder 1 are fixed to supports, where an external frame 4 extending outward from the opening seat 2 is fixed. A guide roller 5 is mounted on the top of the external frame 4 via a rotating shaft. The glass fibers 6 are taut below the central roller 3 and above the guide roller 5, with a fixed inclination angle. Four symmetrical sliding seats 8 are slidably mounted on both sides of the opening seat 2. Two horizontally oriented sliding seats 8... A scraper 7 is fixedly installed between the upper and lower scrapers 7, which fits tightly against the opening of the opening seat 2, so that the slurry scraped off by the scraper 7 flows back to the upper slurry cylinder 1. There is a gap between the upper and lower scrapers 7, and the glass fiber 6 on the guide roller 5 passes through the center of the gap. The upper slurry cylinder 1 is located below the opening seat 2 and has an extension groove 12 that extends obliquely upward. When the glass fiber 6 extends from below the central roller 3 to above the guide roller 5, its inclination angle is such that it only contacts the slurry 17 in the upper slurry cylinder 1, preventing the slurry carried out by the glass fiber 6 from contacting parts other than the scraper 7. The distance between the guide roller 5 and the opening seat 2 is such that the slurry 17 on the glass fiber 6 has solidified when it moves to the guide roller 5. A drying mechanism is mounted on the outer frame 4.

[0025] See Figures 1-3 The opening seat 2 is fixedly mounted with a limiting plate 15 on the outside of the sliding seat 8. A lifting plate 9 is fixedly mounted between the limiting plate 15 on the two sliding seats 8 on one side. A threaded column 10 is rotatably mounted on the limiting plate 15. The threaded column 10 passes through the threaded hole on the lifting plate 9. When the threaded column 10 is twisted, the threaded column 10 moves up and down. The two pushing threads 14 on the threaded column 10 are symmetrical and the pushing directions of the two pushing threads 14 are opposite, so that the two sliding seats 8 on the same side move away or close at the same speed. The sliding seat 8 is attached to the side wall of the opening seat 2 through the slide rail. The threaded column 10 is fixedly mounted with limiting rings 13 on the upper and lower sides of the limiting plate 15 to keep the height of the threaded column 10 unchanged. A knob 16 is fixedly mounted on the top of the threaded column 10. A sliding column 11 is fixedly mounted on the side of the opening seat 2 away from the threaded column 10. The sliding seat 8 on this side is slidably connected to the sliding column 11. The sliding seats 8 on both sides are raised and lowered together through the sliding column 11, changing the distance between the two scrapers 7.

[0026] The glass fiber sizing device of this invention has a simple structure and high working efficiency. It can evenly coat the sizing agent onto the surface of glass fiber and can adapt to glass fiber of different thicknesses and different coating thicknesses. It is easy to adjust, highly practical, and suitable for widespread application.

[0027] For specific usage, please refer to... Figures 1-2When sizing glass fiber 6, slurry 17 is injected into sizing cylinder 1 and immersed to the extension groove 12. Glass fiber 6 is inserted from the upper side of the opening of the opening seat 2, and after passing around the central roller 3, it passes through the gap between the two scrapers 7 and passes over the top of the guide roller 5 and is connected to the winding mechanism. At this time, the winding mechanism operates, pulling glass fiber 6 through the slurry 17 below. The excess slurry 17 is scraped off when it passes the scraper 7. The glass fiber 6 pulled out of sizing cylinder 1 is dried on the outside and wound up after passing through the guide roller 5, thus completing the uniform sizing of glass fiber 6.

[0028] See Figures 1-3 When sizing glass fibers 6 of different thicknesses, the knob 16 is rotated. When the threaded column 10 rotates, the two sections of its pushing threads 14 advance in opposite directions, causing the two sliding seats 8 on the same side to move away or closer at the same speed, thereby driving the scraper 7 to move. The number of rotations of the knob 16 represents the movement distance. By changing the distance between the two scrapers 7, different thicknesses of sizing are applied to glass fibers 6 of different thicknesses. The glass fibers 6 are taut below the center roller 3 and above the guide roller 5, and their inclination is such that they pass through the center of the distance between the scrapers 7, so that the sizing thickness on the upper and lower sides is the same.

[0029] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
