Description

Technical Field

[0001] This utility model relates to the field of glass fiber production technology, specifically to a glass fiber impregnation device with an immersion guiding structure. Background Technology

[0002] Glass fiber is a high-performance inorganic non-metallic material made from molten glass through a special process. In the glass fiber production process, the impregnation treatment of glass fiber is crucial, as it has a profound impact on the subsequent performance of glass fiber and product quality, directly affecting the performance of glass fiber and the quality of subsequent finished products.

[0003] In traditional glass fiber impregnation, a spray impregnation method is used. During spraying, not only is the impregnation liquid wasted, but it is also impossible to ensure that every part of the glass fiber is fully impregnated. In addition, the glass fiber is directly guided into the impregnation device, lacking a structure that allows the glass fiber to be completely immersed in the impregnation liquid, resulting in poor impregnation effect and increased defect rate. Utility Model Content

[0004] The purpose of this invention is to provide a glass fiber impregnation device with an immersion-guided structure to solve the problem in the background art where the spray impregnation method not only wastes impregnation liquid during spraying, but also directly guides the glass fiber into the impregnation device without a structure to completely immerse the glass fiber in the impregnation liquid, resulting in poor impregnation effect of the glass fiber.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a glass fiber impregnation device with an immersion guiding structure, comprising an impregnation tank, which is configured as an open-top box structure, wherein the impregnation tank contains a glass fiber impregnation solution, and two drain pipes are respectively provided at both ends of the impregnation tank, and valves are provided in the drain pipes; the impregnation tank is the main container for the glass fiber impregnation solution.

[0006] A feed hopper is installed on one side of the upper end of the immersion tank, and a discharge hopper is installed on the other side of the upper end of the immersion tank. The upper end of the feed hopper is set as an inclined surface, and a comb-like structure is provided on one side of the top of the inclined surface of the feed hopper. The bottom side of the inclined surface of the feed hopper is close to the limiting plate one. A power roller one is installed in the immersion tank on the side close to the feed hopper, and a power roller two is installed in the immersion tank on the side close to the discharge hopper.

[0007] An upper roller is provided between the first and second power rollers, and the first, second and upper rollers are located above the immersion chamber. Two lower rollers are symmetrically arranged below the immersion chamber. The discharge hopper has the same structure as the feed hopper, and a limiting plate is provided on one side of the inclined surface of the discharge hopper. The two ends of the limiting plate are slidably connected to the inner wall of the discharge hopper.

[0008] By adopting the above technical solution, the glass fiber is fully impregnated during impregnation while maintaining a stable output.

[0009] Preferably, a sealing element is provided at the through port of the immersion box, and the two sides inside the immersion box are inclined. The bottom end of the immersion box and the inclined surface are respectively provided with strip-shaped openings, and an exhaust pipe is installed in the strip-shaped opening of the immersion box.

[0010] By adopting the above technical solution, a sealing element is installed at the port through which the lubrication tank is penetrated, which can effectively prevent leakage of the wetting solution, ensure a clean working environment, and avoid solution loss and waste.

[0011] Preferably, the two ends of the limiting plate are slidably connected to the inner wall of the feed hopper, and a triangular block is provided at the bottom of the limiting plate, and the limiting plate is close to the power roller.

[0012] Using the above technical solution, the glass fiber passes through the triangular block at the bottom of the limiting plate, making it easier for the glass fiber to approach the power roller.

[0013] Preferably, the first power roller, the second power roller, the upper roller, and the two lower rollers are arranged in a W-shape within the immersion chamber, and the two ends of the first power roller, the second power roller, and the upper roller penetrate through the immersion chamber.

[0014] By adopting the above technical solution, the W-shaped arrangement of the roller increases the immersion time and contact area of ​​the glass fiber in the wetting solution, thus ensuring the wetting effect.

[0015] Preferably, the end of the second power roller connected to the motor is fitted with a rotating assembly, and the other end of the rotating assembly is connected to one end of the upper roller. The rotating assembly consists of two drive wheels and a drive belt.

[0016] Using the above technical solution, the transmission between the power roller and the upper roller is achieved through the rotating assembly.

[0017] Preferably, one-way valves are evenly distributed on the surface of the exhaust pipe, and one end of the exhaust pipe is connected to the intake pipe through a pipe.

[0018] By adopting the above technical solution, multiple one-way valves are installed on the surface of the exhaust pipe to allow air bubbles to enter the wetting liquid.

[0019] Preferably, the bottom end of the second limiting plate is provided with a rotating small-diameter roller, and the second limiting plate is close to the second power roller.

[0020] Using the above technical solution, the bottom end of the limiting plate is equipped with a rotating small-diameter roller, which can be adjusted according to the specifications of the glass fiber and production requirements to adapt to the impregnation work of different types of glass fiber.

[0021] Compared with the prior art, the beneficial effects of this utility model are: the glass fiber impregnation device equipped with an immersion guide structure:

[0022] 1. When the device impregnates the glass fiber, the glass fiber is initially combed and guided by the inclined surface and comb-like structure at the upper end of the feed hopper, so that it enters the impregnation box neatly. Then, the limiting plate one and the limiting plate two can respectively limit the position of the glass fiber at the feed and discharge points to prevent the fiber from deviating. The glass fiber is arranged in a W shape on the surface of the power roller one, power roller two, upper roller and lower roller, so that the glass fiber is immersed in the solution in the impregnation box along a specific path, increasing the impregnation time and contact area, and ensuring uniform impregnation.

[0023] 2. During use, the device is equipped with drain pipes and valves at both ends of the impregnation tank to facilitate the discharge and replacement of the impregnation solution. It can also promptly clean up contaminated or diluted solutions to ensure the impregnation effect. At the same time, the inclined sides of the tank and the strip-shaped openings at the bottom and the inclined surfaces are used to install the exhaust pipe. Compressed gas enters the exhaust pipe through the air inlet pipe and enters the impregnation solution through the one-way valve on the surface of the exhaust pipe, which facilitates the discharge of gas in the solution and avoids air bubbles affecting the impregnation quality of glass fibers. The inclined design also helps to concentrate the discharge and recycling of the solution. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figure 1-6 This utility model provides a technical solution: a glass fiber impregnation device with an immersion guide structure, including an impregnation tank 1, a drain pipe 2, a feed hopper 3, a limiting plate 4, a power roller 5, a power roller 6, a rotating assembly 7, an upper roller 8, a lower roller 9, an exhaust pipe 10, an air inlet pipe 11, a discharge hopper 12, and a limiting plate 13;

[0033] Among them, the impregnation tank 1 is configured as a box structure with an open top. The impregnation tank 1 contains the solution for impregnating glass fibers, and two drain pipes 2 are respectively installed at both ends of the impregnation tank 1, and valves are installed in the drain pipes 2. The impregnation tank 1 is the main container for the glass fiber impregnation solution.

[0034] A feed hopper 3 is installed on one side of the upper end of the impregnation tank 1, and a discharge hopper 12 is installed on the other side of the upper end of the impregnation tank 1. The upper end of the feed hopper 3 is set as an inclined surface, and a comb-like structure is provided on one side of the top of the inclined surface of the feed hopper 3. The bottom of the inclined surface of the feed hopper 3 is close to the limiting plate 4. The two ends of the limiting plate 4 are slidably connected to the inner wall of the feed hopper 3. A triangular block is provided at the bottom of the limiting plate 4. The limiting plate 4 is close to the power roller 5. The impregnation tank 1 is located near the feed hopper. A power roller 5 is installed on one side of 3, and a power roller 6 is installed on the side of the immersion box 1 near the discharge hopper 12. A sealing element is provided at the through port of the immersion box 1, and the two sides inside the immersion box 1 are inclined. A strip opening is opened at the bottom end and the inclined surface of the immersion box 1, and an exhaust pipe 10 is installed in the strip opening of the immersion box 1. One-way valves are evenly arranged on the surface of the exhaust pipe 10, and one end of the exhaust pipe 10 is connected to the air inlet pipe 11 through a pipe.

[0035] Referring to the attached diagrams in the instruction manual Figure 1-6 As shown, the impregnation tank 1 contains the solution required for impregnating the glass fibers. When the glass fiber bundle follows a predetermined path, such as... Figure 4As shown, when the glass fiber moves under the drive of the roller, it will be fully immersed in the solution. Since the two sides of the impregnation tank 1 are inclined, the solution is conducive to natural flow under the action of gravity, which promotes solution renewal and allows the glass fiber to come into contact with a more uniform impregnation solution concentration. Furthermore, the exhaust pipe 10 installed in the strip opening at the bottom of the impregnation tank 1 and the inclined surface, through connection with the air inlet pipe 11, can fill the impregnation solution with gas, such as air or nitrogen. At this time, the one-way valve on the surface of the exhaust pipe 10 ensures that the gas can only enter the impregnation solution in one direction. The gas fills in forms bubbles, which disturb the impregnation solution during the rising process, further improving the impregnation efficiency and uniformity of the glass fiber.

[0036] During use, the glass fiber bundle enters the impregnation tank 1 from the feed hopper 3. The inclined surface design at the upper end of the feed hopper 3 facilitates the smooth sliding of the glass fiber. The comb-like structure on one side of the top end performs preliminary combing of the fiber bundle, separating the intertwined fibers and allowing them to enter in a relatively neat state and move towards the power roller 5. Since the two ends of the limiting plate 4 slide on the inner wall of the feed hopper 3, the position can be adjusted according to the actual situation such as the thickness of the glass fiber bundle. The triangular block at the bottom of the limiting plate 4 can further guide the fiber bundle to move accurately close to the power roller 5.

[0037] An upper roller 8 is provided between the first power roller 5 and the second power roller 6. The first power roller 5, the second power roller 6, and the upper roller 8 are located above the impregnation chamber 1. Two lower rollers 9 are symmetrically arranged below the impregnation chamber 1. The discharge hopper 12 has the same structure as the feed hopper 3. A limit plate 2 13 is provided on one side of the inclined surface of the discharge hopper 12, and the two ends of the limit plate 2 13 are slidably connected to the inner wall of the discharge hopper 12. The first power roller 5, the second power roller 6, and the upper roller 8 are also located above the impregnation chamber 1. Two lower rollers 9 are arranged in a W-shape in the immersion tank 1. The two ends of the rods of the first power roller 5, the second power roller 6 and the upper roller 8 pass through the immersion tank 1. The end of the second power roller 6 connected to the motor is fitted with one end of the rotating assembly 7. The other end of the rotating assembly 7 is connected to one end of the upper roller 8. The rotating assembly 7 consists of two drive wheels and a drive belt. The bottom end of the second limiting plate 13 is equipped with a rotating small-diameter roller. The second limiting plate 13 is close to the second power roller 6.

[0038] Referring to the attached diagrams in the instruction manual Figure 1-6 As shown, the first power roller 5, the second power roller 6, the upper roller 8, and the two lower rollers 9 are arranged in a W-shape within the immersion chamber 1, as shown. Figure 4As shown, the glass fibers form a W-shaped arrangement between the first power roller 5, the second power roller 6, the upper roller 8, and the two lower rollers 9. This creates a specific travel path for the glass fibers within the impregnation tank 1, increasing the immersion time and contact area in the impregnation solution and ensuring effective impregnation. During use, the two lower rollers 9 buffer the power from the first power roller 5, the second power roller 6, and the upper roller 8. The second power roller 6 and the first power roller 5 are connected to their respective motors. After the two motors start, the second power roller 6 and the first power roller 5 begin to rotate in the same direction and at the same speed. Through the rotating assembly 7, the second power roller 6 transmits power to the upper roller 8, achieving rotation in the same direction and at the same speed. Figure 4 As shown;

[0039] The fully impregnated glass fiber bundles are discharged from the discharge hopper 12. Since the discharge hopper 12 has the same structure as the feed hopper 3, during use, the position of the discharged glass fiber bundles is limited by adjusting the sliding height of the two ends of the limiting plate 2 13 on the inner wall of the discharge hopper 12 to prevent them from deviating. The small-diameter roller rotating at the bottom of the limiting plate 2 13 can reduce the friction when the fiber bundles are discharged, allowing the fiber bundles to leave the impregnation tank 1 more smoothly. The drain pipes 2 at both ends of the impregnation tank 1 can be opened to drain the solution when the impregnation solution needs to be replaced or the equipment needs to be cleaned. The sealing element set at the through port of the impregnation tank 1 can effectively prevent solution leakage and ensure the normal operation of the device.

[0040] Working principle: When using this glass fiber impregnation device equipped with an immersion-guided structure, the glass fiber bundle enters the device from the comb-like structure at the upper end of the feed hopper 3. The comb-like structure can straighten the tangled fibers. Then, the glass fiber passes through the triangular block at the bottom of the limiting plate 4 and enters the impregnation tank 1. At this time, the glass fiber passes through the power roller 5, one lower roller 9, power roller 6, upper roller 8, and another lower roller 9 in the impregnation tank 1, forming a W-shaped structure. Figure 4 As shown, during use, both the first power roller 5 and the second power roller 6 are started by a motor. Simultaneously, the rotating assembly 7 transmits power from the second power roller 6 to the upper roller 8, ensuring a uniform speed of glass fiber transfer during impregnation. The W-shaped roller layout allows the glass fiber to form a specific path within the impregnation tank 1, increasing the immersion time and contact area of ​​the glass fiber in the impregnation solution and ensuring the impregnation effect. The exhaust pipe 10 at the bottom of the impregnation tank 1 is connected to compressed air or nitrogen through the air inlet pipe 11. Because the surface of the exhaust pipe 10 is equipped with multiple one-way valves, the gas continuously enters the impregnation solution, causing the impregnation solution to be angled. This ensures that the fiber can continuously contact fresh impregnation solution. At the same time, the movement of the bubbles can break the boundary layer that may form on the surface of the glass fiber, enhancing the penetration ability of the impregnation solution into the fiber, making the impregnation deeper and more uniform, thereby significantly improving the impregnation quality of the glass fiber and increasing the overall practicality.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
