Description

Technical Field

[0001] This invention relates to the field of glass fiber production, and more specifically, to a glass fiber impregnation apparatus. Background Technology

[0002] Fiberglass mesh is made of woven fiberglass fabric as the base material, coated with a polymer anti-emulsion, giving it excellent alkali resistance, flexibility, and high tensile strength in both warp and weft directions. It can be widely used for thermal insulation, waterproofing, fireproofing, and crack resistance of interior and exterior walls in buildings. Alkali-resistant fiberglass mesh is the primary type. The production of fiberglass mesh involves several processes, including unwinding, impregnation with a primer, drying, air cleaning of the primer, coating with a top coat of adhesive, and rewinding.

[0003] Existing impregnation equipment requires workers to manually immerse the glass fibers in the adhesive solution during the impregnation process. This results in poor guidance and increases the workload for workers, thus reducing the practicality of the equipment.

[0004] To address the aforementioned issues, Chinese Patent No. CN221558852U discloses an impregnation device for producing alkali-resistant glass fiber impregnated mesh. In use, one end of the glass fiber is passed through the bottom of a transmission roller, where it is crushed and driven into a groove. Then, guided by a first guide roller, it is transferred to a second guide roller. The second guide roller primarily presses the fiber against the lower end of the adhesive liquid surface, ensuring contact with the liquid and achieving impregnation. The fiber is then wound up by a take-up shaft, which can be removed from the slot and turntable for replacement by rotating a retaining ring, thus improving the device's practicality. While this achieves automated impregnation and reduces manual operation, the adhesive remains undisturbed inside the device for extended periods, leading to adhesive stratification or solidification, resulting in insufficient impregnation of the glass fiber and reduced glass fiber quality. Summary of the Invention

[0005] In view of the problems existing in the prior art, the purpose of the present invention is to provide a glass fiber impregnation device.

[0006] To solve the above problems, the present invention adopts the following technical solution.

[0007] A glass fiber impregnation apparatus includes a heated impregnation tank. First guide rollers are provided on both sides of the upper surface of the heated impregnation tank. Second guide rollers are symmetrically rotatably connected to the front and rear sides of the inner surface of the heated impregnation tank. A support frame is fixedly connected to one side of the heated impregnation tank. A scraping component is provided at the middle of the front and rear sides of the inner surface of the heated impregnation tank to prevent the adhesive from separating and sticking to the bottom.

[0008] The scraping assembly includes a first support plate fixed at the middle of the front and rear sides of the inner surface of the heating impregnation tank, and a second support plate fixed on both sides of the front and rear sides of the inner surface of the heating impregnation tank. A first drive motor is fixedly connected to the upper surface of the first support plate, and a first gear is fixedly connected to the output end of the first drive motor. A drive component is provided inside the second support plate. A movable frame is slidably connected to the bottom of the heating impregnation tank. Scrapers are uniformly fixedly connected to the inner surface of the movable frame. A C-shaped frame is fixedly connected to the upper surface of the movable frame, and a through groove is formed on the upper surface of the C-shaped frame.

[0009] Furthermore, the driving component includes a first rotating shaft that rotates inside the second support plate and a first gear fixed to the output end of the first drive motor. A second gear is fixedly connected to the outer surface of the first rotating shaft, and a timing belt is sleeved on the outer surface of the second gear. A circular plate is fixedly connected to the bottom of the first rotating shaft, and a driving block is fixedly connected to the lower surface of the circular plate.

[0010] Furthermore, the first gear is located inside the timing belt, and the first gear meshes with the timing belt. The scraper has a slot in the middle. The circular plate is located above the C-shaped frame. The bottom of the drive block passes through the inside of the slot and slides against each other. The width of the moving frame is slightly smaller than the width inside the heating impregnation tank.

[0011] Furthermore, a defoaming assembly for shaking the glass fiber is provided at the bottom of the heating impregnation tank. The defoaming assembly includes two rectangular fixed rods fixed to the bottom of the heating impregnation tank and two movable plates fixed to the scraper. The outer surface of the rectangular fixed rods is fitted with a telescopic sleeve, and a sliding rod is fixedly connected to the outer surface of the telescopic sleeve. A striking frame is fixedly connected to the top of the telescopic sleeve, and a wave groove is opened inside the movable plate.

[0012] Furthermore, the rectangular fixing rod is rectangular and located between the two moving plates. The striking frame is arranged on both sides of the third guide roller, and the moving plate is located inside the scraper groove.

[0013] Furthermore, two slide rods are provided, and the two slide rods are fixed symmetrically on the outer surface of the telescopic sleeve. One side of each slide rod extends into the interior of the wave groove and slides against each other.

[0014] Furthermore, three stirring blades are uniformly fixedly connected to the outer surface of the first rotating shaft near the circular plate, and the stirring blades are located above the second support plate.

[0015] Furthermore, the upper surface of the support frame is provided with a dust removal assembly for beating the glass fiber. The dust removal assembly includes a dust removal chamber fixed to the upper surface of the support frame. The dust removal chamber has openings on both sides. A second drive motor is fixedly connected to the front and rear sides of one side of the dust removal chamber. A second rotating shaft is fixedly connected to the output end of the second drive motor. Three pressure rods are evenly fixedly connected to the outer surface of the second rotating shaft. Fixed shafts are fixedly connected to the front and rear sides of both sides of the inner surface of the dust removal chamber. Three striking plates are rotatably connected to the outer surface of the fixed shafts. A coil spring is provided at the connection between the striking plates and the fixed shafts.

[0016] Furthermore, the other end of the second rotating shaft extends into the interior of the ash cleaning chamber and is rotatably connected to one side of the inner surface of the ash cleaning chamber, and the pressure rod corresponds one-to-one with the striking plate.

[0017] Furthermore, the three striking plates on the same side form a group, and the two groups of striking plates are staggered with each other, with the lower surfaces of the two groups of striking plates flush.

[0018] Furthermore, a dust collection assembly is provided on the front side of the dust removal chamber. The dust collection assembly includes a filter screen that slides on the front side of the dust removal chamber. A limit plate is fixedly connected to the front side of the filter screen. A negative pressure machine is fixedly connected to the lower surface of the dust removal chamber. A through hole is opened at the bottom of the dust removal chamber.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] 1. This solution is equipped with a glue scraping component. The first drive motor drives the moving frame to move back and forth in the bottom of the heating and impregnation tank through transmission. This can stir the bottom of the glue, making the glue more uniform and avoiding stratification. It can also make the glue heat more evenly.

[0021] 2. This solution incorporates a defoaming component. The sliding rod slides relative to the inside of the corrugated groove, causing the height of the sliding rod to continuously rise and fall. Due to the limiting effect of the rectangular fixing rod, the sliding rod drives the striking frame to rise and fall synchronously through the telescopic sleeve. When the striking frame rises and falls, the upper and lower plates of the striking frame continuously strike the upper and lower surfaces of the glass fiber to force out the air bubbles, ensuring that the glass fiber and the adhesive are in full contact and avoiding affecting the quality of the glass fiber.

[0022] 3. This solution incorporates stirring blades. When the first rotating shaft synchronously drives the stirring blades to rotate, the stirring blades agitate the adhesive solution. Combined with the moving frame and scraper, this allows the adhesive solution in the upper half of the heating impregnation tank to mix with the adhesive solution in the lower half, further improving the uniformity of heating of the adhesive solution and maintaining the adhesive solution in a liquid state. This allows for multiple different operations to be performed simultaneously with reduced driving force, ensuring excellent glass fiber impregnation results. Attached Figure Description

[0039] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0040] Please see Figures 1 to 8 A glass fiber impregnation device includes a heating impregnation tank 1, with first guide rollers 2 arranged on both sides of the upper surface of the heating impregnation tank 1, and second guide rollers 4 symmetrically rotatably connected to the front and rear sides of the inner surface of the heating impregnation tank 1. A support frame 3 is fixedly connected to one side of the heating impregnation tank 1, and a scraping component 5 is provided at the middle of the front and rear sides of the inner surface of the heating impregnation tank 1 to prevent the adhesive from separating and sticking to the bottom.

[0041] like Figure 2-4 As shown, the glue scraping assembly 5 includes a first support plate 51 fixed at the middle of the front and rear sides of the inner surface of the heating glue impregnation tank 1, and a second support plate 511 fixed on both sides of the front and rear sides of the inner surface of the heating glue impregnation tank 1. A first drive motor 52 is fixedly connected to the upper surface of the first support plate 51, and a first gear 53 is fixedly connected to the output end of the first drive motor 52. A drive component is provided inside the second support plate 511. A movable frame 57 is slidably connected to the bottom of the heating glue impregnation tank 1. Scrapers 58 are evenly fixedly connected to the inner surface of the movable frame 57. A C-shaped frame 56 is fixedly connected to the upper surface of the movable frame 57, and a through groove 513 is opened on the upper surface of the C-shaped frame 56.

[0042] The driving component includes a first rotating shaft 59 that rotates inside the second support plate 511 and a first gear 53 fixed to the output end of the first drive motor 52. A second gear 54 is fixedly connected to the outer surface of the first rotating shaft 59. A timing belt 512 is sleeved on the outer surface of the second gear 54. A circular plate 510 is fixedly connected to the bottom of the first rotating shaft 59. A driving block 514 is fixedly connected to the lower surface of the circular plate 510.

[0043] The first gear 53 is located inside the timing belt 512. The first gear 53 meshes with the timing belt 512. The scraper 58 has a slot in the middle. The circular plate 510 is located above the C-shaped frame 56. The bottom of the drive block 514 passes through the inside of the through groove 513 and slides against each other. The width of the moving frame 57 is slightly smaller than the width inside the heating impregnation box 1.

[0044] When impregnating the glass fiber with adhesive, the glass fiber passes over the first guide roller 2 and then under the second guide roller 4 and the third guide roller 7, so that the glass fiber is completely immersed in the adhesive. At this time, the first drive motor 52 is turned on to drive the first gear 53 to rotate. The first gear 53 drives the two second gears 54 to rotate synchronously through the synchronous belt 512. The second gears 54 drive the circular plate 510 to rotate through the first rotating shaft 59. The drive block 514 moves in a circular motion with the circular plate 510. The drive block 514 moves back and forth inside the through groove 513, which drives the C-shaped frame 56 to move back and forth in a horizontal direction. This drives the moving frame 57 to move inside the heating impregnation tank 1, which can stir the bottom of the adhesive. This can stir the adhesive that is adhering to the bottom of the heating impregnation tank 1, making the adhesive more uniform and avoiding stratification. It can also make the adhesive heat more evenly.

[0045] like Figure 5-6 As shown, a defoaming assembly 55 for shaking glass fibers is provided at the bottom of the heating impregnation tank 1. The defoaming assembly 55 includes two rectangular fixed rods 554 fixed to the bottom of the heating impregnation tank 1 and two movable plates 551 fixed to the scraper 58. The outer surface of the rectangular fixed rods 554 is fitted with a telescopic sleeve 555. A sliding rod 556 is fixedly connected to the outer surface of the telescopic sleeve 555. A striking frame 553 is fixedly connected to the top of the telescopic sleeve 555. A wave groove 552 is opened inside the movable plate 551.

[0046] The rectangular fixing rod 554 is rectangular and is located between the two moving plates 551. The striking frame 553 is arranged on both sides of the third guide roller 7, and the moving plate 551 is located inside the groove of the scraper 58.

[0047] There are two slide rods 556. The two slide rods 556 are fixed on the outer surface of the telescopic sleeve 555 in an axisymmetric manner. One side of the slide rod 556 extends into the interior of the wave groove 552 and slides against each other.

[0048] Three stirring blades 515 are evenly and fixedly connected to the outer surface of the first rotating shaft 59 near the circular plate 510, and the stirring blades 515 are located above the second support plate 511.

[0049] When glass fiber enters the interior of the adhesive, air bubbles will exist inside the glass fiber. When the adhesive adheres to the surface of the glass fiber, small air bubbles between the glass fiber and the adhesive cannot be discharged in time. The air bubbles form micro-cavities inside the material, causing stress to concentrate around the air bubbles, which becomes the starting point for crack initiation, reducing the tensile, bending and compressive strength of the material, and having a great impact on the quality of the glass fiber.

[0050] Therefore, before impregnating the glass fiber, the glass fiber needs to pass through the interior of the two striking frames 553. As the moving frame 57 swings back and forth under the action of the first drive motor 52, the scraper 58 drives the moving plate 551 to move back and forth synchronously, causing the corrugated groove 552 to move synchronously. This allows the slide rod 556 to slide relative to each other inside the corrugated groove 552. Due to the special shape of the corrugated groove 552, the height of the slide rod 556 continuously rises and falls. Due to the limiting effect of the rectangular fixing rod 554, the slide rod 556 drives the striking frame 553 synchronously through the telescopic sleeve 555. As the frame 553 moves up and down, the two plates on the upper and lower parts of the frame 553 continuously strike the upper and lower surfaces of the glass fiber to force out air bubbles and ensure that the glass fiber and the adhesive are in full contact to avoid affecting the quality of the glass fiber. When the first rotating shaft 59 rotates, it will simultaneously drive the stirring blade 515 to rotate. The stirring blade 515 stirs the adhesive. Together with the moving frame 57 and the scraper 58, the adhesive in the upper half of the heating impregnation tank 1 can be mixed with the adhesive in the lower half, further improving the uniform heating effect of the adhesive and maintaining the adhesive in a liquid state.

[0051] like Figure 7-8 As shown, the upper surface of the support frame 3 is provided with a dust removal assembly 6 for beating the glass fiber. The dust removal assembly 6 includes a dust removal chamber 61 fixed to the upper surface of the support frame 3. The dust removal chamber 61 has openings 67 on both sides. A second drive motor 62 is fixedly connected to the front and rear sides of one side of the dust removal chamber 61. A second rotating shaft 63 is fixedly connected to the output end of the second drive motor 62. Three pressure rods 64 are evenly fixedly connected to the outer surface of the second rotating shaft 63. Fixed shafts 69 are fixedly connected to the front and rear sides of both sides of the inner surface of the dust removal chamber 61. Three striking plates 65 are rotatably connected to the outer surface of the fixed shaft 69. A coil spring 66 is provided at the connection between the striking plate 65 and the fixed shaft 69.

[0052] The other end of the second rotating shaft 63 extends into the interior of the ash cleaning chamber 61 and is rotatably connected to one side of the inner surface of the ash cleaning chamber 61. The pressure rod 64 corresponds one-to-one with the striking plate 65. The three striking plates 65 on the same side form a group. The two groups of striking plates 65 are staggered and the lower surfaces of the two groups of striking plates 65 are flush.

[0053] like Figure 8 As shown, a dust collection assembly 68 is provided on the front side of the dust collection chamber 61. The dust collection assembly 68 includes a filter screen 681 that slides on the front side of the dust collection chamber 61. A limit plate 682 is fixedly connected to the front side of the filter screen 681. A negative pressure machine 683 is fixedly connected to the lower surface of the dust collection chamber 61. A through hole 684 is provided at the bottom of the dust collection chamber 61.

[0054] Before impregnation, the surface of the glass fiber may have absorbed some dust during long-term transportation. The presence of this dust will result in insufficient adhesion between the adhesive and the glass fiber during the subsequent impregnation process.

[0055] During fiber optic transmission, the fiber optic cable enters the dust removal chamber 61 through the port 67. The fiber optic cable passes under the impact plate 65 and exits through the port 67 on the other side. The second drive motor 62 is activated, driving the second rotating shaft 63 to rotate. Simultaneously, the second rotating shaft 63 drives three pressure rods 64 in a circular motion. During rotation, one end of each pressure rod 64 presses downwards against the other end of the impact plate 65, forcing the impact plate 65 to rotate on the surface of the fixed shaft 69 and compress the coil spring 66. When the pressure rod 64 rotates away from one end of the striking plate 65, the striking plate 65 is no longer squeezed by the pressure rod 64, and the coil spring 66 quickly resets, driving the striking plate 65 back to its initial position. The striking plate 65 beats the transmitted glass fiber, which can effectively knock off the stubborn dust on the surface of the glass fiber. Compared with existing equipment, the combination of negative pressure machine and fan has significantly improved the effect of adsorbing dust on the surface of glass fiber. The pressure rod 64 continues to rotate one revolution with the second rotating shaft 63 to realize the beating operation of the striking plate 65 again.

[0056] The dust that is knocked off spreads into the internal environment of the dust removal chamber 61. If it is not dealt with in time, the dust will continue to fall on the surface of the glass fiber. Therefore, the negative pressure machine 683 is turned on to evacuate the inside of the dust removal chamber 61 through the through hole 684. The dust scattered inside the dust removal chamber 61 is moved towards the limiting plate 682 with the airflow, so that the dust is adsorbed on the surface of the limiting plate 682, ensuring that the dust falling from the surface of the glass fiber can be collected quickly. After a period of operation, the limiting plate 682 is pulled to move the filter screen 681 out of the inside of the dust removal chamber 61 to clean the dust on the surface of the filter screen 681. After cleaning, the filter screen 681 is reinserted into the inside of the dust removal chamber 61 for continued use.

[0057] Instructions for use: Turn on the first drive motor 52 to drive the first gear 53 to rotate. The first gear 53 drives the two second gears 54 to rotate synchronously through the synchronous belt 512. The second gears 54 drive the circular plate 510 to rotate through the first rotating shaft 59. The drive block 514 moves in a circular motion with the circular plate 510. The drive block 514 moves back and forth inside the through groove 513, which drives the C-shaped frame 56 to move back and forth in a horizontal direction. This causes the moving frame 57 to move inside the heating impregnation tank 1, which can stir the bottom of the glue and stir the glue adhering to the bottom of the heating impregnation tank 1, making the glue more uniform and avoiding stratification.

[0058] The back-and-forth moving frame 57 drives the moving plate 551 to move back and forth synchronously via the scraper 58, thereby driving the corrugated groove 552 to move synchronously. This causes the slide rod 556 to slide relative to the inside of the corrugated groove 552. Due to the special shape of the corrugated groove 552, the slide rod 556 will continuously rise and fall, thereby driving the striking frame 553 to rise and fall synchronously via the telescopic sleeve 555. When the striking frame 553 rises and falls, the upper and lower plates of the striking frame 553 will continuously strike the upper and lower surfaces of the glass fiber to force out the air bubbles and ensure that the glass fiber is in full contact with the adhesive, so as to avoid the air bubbles affecting the quality of the glass fiber impregnation.

[0059] By rotating the pressure rod 64 to press one end of the striking plate 65, the striking plate 65 completes a striking operation under the action of the coil spring 66, knocking off the dust on the surface of the glass fiber. The negative pressure machine 683 evacuates the inside of the dust removal chamber 61 through the through hole 684, causing the dust scattered inside the dust removal chamber 61 to move towards the limiting plate 682 with the airflow, so that the dust is adsorbed on the surface of the limiting plate 682, ensuring that the dust can be quickly collected after falling from the surface of the glass fiber. After a period of operation, the limiting plate 682 is pulled to drive the filter screen 681 out of the inside of the dust removal chamber 61, cleaning the dust on the surface of the filter screen 681. After cleaning, the filter screen 681 can be reinserted into the inside of the dust removal chamber 61 for continued use.
