Description

Technical Field

[0001] This invention relates to the field of glass fiber mat manufacturing technology, specifically to a high-performance glass fiber mat drying and molding system using a composite water-based adhesive. 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. Glass fiber is commonly used as a reinforcing material in composite materials, as well as an electrical insulation material and a thermal insulation material. It is a new material industry that the country strongly encourages to develop.

[0003] In the prior art, Chinese patent document CN105716384A3 discloses a design where the fan is located on the left side of the heater, and the left parts of chambers B, C, and D are each connected to the outside of the housing via an exhaust duct. The right parts of chambers B, C, and D are each connected to three hot air distribution units via an exhaust duct. This washing and drying box has high drying efficiency and good drying effect. However, in practical applications, when hot air enters the hot air distribution unit through the inlet and outlet of the outer and inner square closed ducts, or through a right-angled air inlet duct, hot air turbulence is likely to occur. Turbulence during the flow process may cause local increases in hot air velocity and decreases in other areas, which may also lead to uneven drying effect. In addition, consistent with the traditional method, the glass fiber mat is usually impregnated with adhesive before drying and then directly put into the drying oven for drying. It is often difficult to ensure that the cured adhesive is evenly distributed on the fiber mat, and there may be too much or too little in some areas, which affects the product quality. Therefore, this application discloses a high-performance glass fiber mat drying and molding system with composite water-based adhesive to ensure that the glass fiber mat can be heated and molded evenly. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a high-performance glass fiber mat drying and molding system with a composite water-based adhesive, which has advantages such as enabling uniform heating of the glass fiber mat and solving a series of problems such as poor drying effect.

[0007] Preferably, the first guide roller has a U-shaped cross-section, and the second guide roller has an inverted U-shaped cross-section, opposite to that of the first guide roller, with the second guide roller located near the feed inlet on the side of the drying chamber.

[0008] Preferably, an upper guide box is provided at the top of the interior of the drying box, the top of the upper guide box is connected to the air duct, and the lower two sides of the upper guide box are both convex arc-shaped. A lower drying guide plate adapted to the drying box is provided at the bottom of the drying box, and a guard plate is provided at both ends of the lower drying guide plate. The cross surface of the lower drying guide plate is arranged in an inverted "V" shape, and a through groove adapted to the top of the conveyor belt is provided on both guard plates.

[0009] Preferably, the top surface of the drying guide plate is provided with a plurality of guide grooves arranged at equal intervals, and the guide grooves are arranged in a downwardly concave semi-circular arc shape.

[0010] Preferably, rotating rollers are equidistantly arranged and rotatably mounted in the center of the drying box, and the height of the side closer to the pretreatment box is the same as the height of the second guide roller, and the rotating rollers closer to the static elimination box are arranged in a downward slope.

[0011] Preferably, the electrostatic eliminator box has three electrostatic eliminator rollers arranged at equal intervals inside, and the outer surface of the electrostatic eliminator rollers is grooved.

[0012] Preferably, one side of the extrusion roller is aligned with the conveyor belt, and a slide rail is fixedly installed above the other side. Two sliders are slidably arranged above the slide rail, and two movable baffles are respectively installed at one end of the two sliders. A lead screw with two opposite threaded sections is rotatably installed on one side of the slide rail, and the lead screw is threadedly connected to the two movable baffles respectively. A pressure roller that abuts against the glass fiber felt is fixedly installed in the middle of the slide rail.

[0013] Preferably, the cutting module includes a fixed rod fixedly installed on the discharge assembly and a sliding block slidably sleeved on the fixed rod. A cylinder is provided on one side of the sliding block, and a cutter is provided at the bottom telescopic end of the cylinder.

[0014] Preferably, the discharge assembly has an inclined guide plate on one side near the conveyor belt, and the other end of the guide plate is aligned with the middle of the extrusion roller.

[0015] Compared with the prior art, the present invention provides a high-performance glass fiber mat drying and molding system with composite water-based adhesive, which has the following beneficial effects: 1. This high-performance glass fiber mat drying and molding system for composite water-based adhesives utilizes an upper guide box, rotating rollers, and a lower guide plate inside the drying chamber. When the glass fiber mat enters the drying chamber via a conveyor belt, it is conveyed to the rotating rollers. These rollers adjust the conveying position of the fiber mat during the drying process, causing it to rise a certain distance, thus increasing the reserved space below and ensuring uniform heating throughout the process to improve drying efficiency. During drying, hot air is conveyed to the upper guide box via ductwork. The convex arc shape at the bottom of the upper guide box guides and distributes the hot air, ensuring it evenly covers the entire surface of the fiber mat. Then, the hot air moves downwards and is evenly distributed into the guide grooves on the lower guide plate and the protective plate. The downward-recessed semi-circular arc shape of these guide grooves guides the hot air flow upwards towards the lower surface of the fiber mat, increasing drying efficiency and preventing overheating when the hot air flows towards curved areas.

[0016] 2. This high-performance glass fiber mat drying and molding system for composite water-based adhesives features a pretreatment box. During the pretreatment, the glass fiber mat undergoes uniform processing. First, the glass fiber mat passes through a first guide roller, which is U-shaped with inclined rollers on both sides. As the glass fiber mat passes through the first guide roller, unevenly distributed cured adhesive on the mat flows towards the center. Then, the glass fiber mat passes through the second guide roller, which is an inverted U-shape. As the glass fiber mat passes through the second guide roller, the cured adhesive flows from the center outwards. This combination ensures that the cured adhesive on the glass fiber mat is evenly distributed and penetrates the interior of the mat, preventing localized over- or under-cured adhesive distribution and improving product quality and consistency.

[0017] 3. This high-performance glass fiber mat drying and molding system for composite water-based adhesives features a discharge assembly. Two movable baffles within the discharge assembly move closer together or further apart, and a slider on one side slides along a guide rail for positioning and correction. During correction or guidance, a pressure roller effectively holds the glass fiber mat in place, assisting the movable baffles. This prevents material misalignment during processing, improving product accuracy and consistency. When cutting is required, a sliding block on the fixed rod moves the cutter to the desired width, at which point a cylinder pushes the cutter downwards to cut the glass fiber mat. When cutting is no longer needed, the cutter can be retracted. This allows for pre-roll cutting of the glass fiber mat, facilitating subsequent storage, transportation, and use, while also improving production efficiency and product quality.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] As described in the background section, there are shortcomings in the existing technology. In order to solve the above-mentioned technical problems, this application proposes a high-performance glass fiber mat drying and molding system with composite water-based adhesive.

[0022] In one typical implementation of this application, such as Figures 1-8As shown, a high-performance glass fiber mat drying and molding system using a composite water-based adhesive includes a base 1, a control box on one side of the base 1, a conveyor belt 2 at the top of the base 1, a drive motor 3 below the conveyor belt 2, a drying chamber 7 above the middle of the conveyor belt 2, a pretreatment chamber 4 and an antistatic chamber 17 on both sides of the drying chamber 7, and a discharge assembly 19 fixedly connected to one end of the conveyor belt 2; an air inlet duct 8 is provided on the back of the drying chamber 7, and a fan 9 is fixedly installed at the top of the drying chamber 7, with an air duct 10 at one end of the fan 9 extending through the top of the drying chamber 7; the discharge assembly 19 is provided with extrusion drying components arranged sequentially from the end closest to the conveyor belt 2 to the end furthest from the conveyor belt 2. The system includes a pressing roller 21 for the glass fiber mat, a movable baffle 24 for correction, a tension roller 27 for increasing the tension of the glass fiber mat, a cutting module for dividing the glass fiber mat, a discharge guide roller 32 for conveying the glass fiber mat to an external roll mill, and a servo motor 33 as the drive source. The antistatic box 17 contains three antistatic rollers 18 arranged at equal intervals, with grooved surfaces on their outer surfaces. During production, after the glass fiber mat undergoes forming and impregnation, it is moved forward by the conveyor belt 2. During this process, the pretreatment box 4 uniformly treats the glass fiber mat to ensure proper treatment of the impregnated curing material. Subsequently, the glass fiber mat is conveyed to the drying box 7 for drying. During the drying process, the fan 9 at the top of the drying chamber 7 generates heat and transfers it to the interior of the drying chamber 7 through the air duct 10, thus drying the glass fiber mat. After drying, the glass fiber mat has solidified and formed, and has a certain strength. Subsequently, the static elimination box 17 eliminates static electricity from the glass fiber mat. After static elimination, the glass fiber mat is conveyed to the discharge assembly 19 for discharge and collected by the mat winding machine. When the discharge assembly 19 is operating, the glass fiber mat is first compressed by the extrusion roller 21, making the glass fiber mat more compact and increasing the density and stability of the material. This helps to maintain the stability of shape and performance during subsequent processing and use. The compressed glass fiber is then passed through the rear... Two movable baffles 24 correct the material's position during subsequent processing, preventing material deviation and improving processing accuracy and consistency. The material accurately enters the tension roller 27, where it is tensioned by the discharge guide roller 32. The tension roller 27 helps maintain tension on the fiberglass mat, preventing material loosening or wrinkling and ensuring neatness and compactness of the winding. A cutting module is located between the tension roller 27 and the discharge guide roller 32 to cut the fiberglass mat before winding, facilitating subsequent storage, transportation, and use, while also improving production efficiency and product quality.

[0023] Furthermore, in the above scheme, such as Figure 2 , Figure 3As shown, the pretreatment box 4 is equipped with a first guide roller 5 and a second guide roller 6. Both the first guide roller 5 and the second guide roller 6 consist of three rollers, and the outer surface of the rollers of the first guide roller 5 and the second guide roller 6 are covered with rubber sleeves. The cross-section of the first guide roller 5 is U-shaped, and the cross-section of the second guide roller 6 is an inverted U-shape. The second guide roller 6 is located near the feed inlet of the drying box 7. When the glass fiber mat is uniformly treated in the pretreatment box 4, the glass fiber mat first passes through the first guide roller 5. The first guide roller 5 is U-shaped, and the rollers on both sides are inclined. Therefore, when the glass fiber mat passes through the first guide roller 5, the cured adhesive impregnated on the glass fiber mat is unevenly distributed upwards. The flow of the adhesive from the center outwards is directed towards the middle. The fiberglass mat then passes through the first guide roller 5, while the second guide roller 6 is an inverted "U" shape, opposite to the first guide roller 5. This causes the cured adhesive on the fiberglass mat to flow from the center outwards as it passes through the second guide roller 6. This combination ensures that the cured adhesive is evenly distributed on the fiberglass mat and penetrates its interior, preventing excessive or insufficient adhesive distribution in certain areas. This improves product quality and consistency. Both the first guide roller 5 and the second guide roller 6 consist of three rollers, and each roller has a rubber sleeve on its outer surface. This helps ensure that the fiberglass mat receives uniform support and pressure as it passes through, further facilitating the even distribution of the cured adhesive on the fiberglass mat.

[0024] Furthermore, in the above scheme, such as Figure 4 , Figure 8As shown, an upper guide box 11 is installed at the top of the drying chamber 7. The top of the upper guide box 11 is connected to the air duct 10. The lower sides of the upper guide box 11 are both convex arc-shaped. A lower drying guide plate 13 adapted to the drying chamber 7 is installed at the bottom of the drying chamber 7. Both ends of the lower drying guide plate 13 are equipped with guard plates 14. The cross surface of the lower drying guide plate 13 is shaped like an inverted "V". Both guard plates 14 have through grooves 15 adapted to the top of the conveyor belt 2. Several guide grooves 16 are evenly arranged on the top surface of the lower drying guide plate 13. The guide grooves 16 are concave semi-circular arc-shaped. The interior of the drying chamber 7... Rotating rollers 12 are equidistantly arranged and rotatably mounted in the middle section. The height of the rollers 12 near the pretreatment box 4 is the same as the height of the second guide roller 6. The rollers 12 near the antistatic box 17 are arranged in a downward slope. When the glass fiber mat enters the drying box 7 via the conveyor belt 2, the fiber mat will be conveyed onto the rotating rollers 12 in the drying box 7. The function of these rotating rollers 12 is to adjust the conveying position of the fiber mat during the drying process, causing it to rise a certain distance, thereby increasing the reserved space below and ensuring that the fiber mat can be heated evenly throughout the process, thus improving the drying effect. In particular, the height of the rollers 12 near the pretreatment box 4 is... The consistent height of the second guide rollers 6 helps maintain stable transport of the fiber felt. After the glass fiber felt is placed inside the drying chamber 7, the upper guide box 11 is connected to the air duct 10. Hot air is transported from the air duct 10 to the upper guide box 11. The convex arc shape at the bottom of the upper guide box 11 guides and distributes the hot air, ensuring that the hot air evenly covers the entire surface of the fiber felt. Then, during its downward movement, the hot air is evenly distributed into the guide grooves 16 on the lower drying guide plate 13 and the guard plate 14. The downwardly recessed semi-circular arc shape of these guide grooves 16 guides the hot air flow upwards towards the lower surface of the fiber felt, increasing the drying efficiency. This design improves drying efficiency and prevents overheating when hot air flows towards curved sections. The inverted "V" shape of the lower drying guide plate 13 also helps to evenly distribute hot air onto the surface of the fiber felt. Furthermore, at the bottom of the drying chamber 7, both ends of the lower drying guide plate 13 are equipped with protective plates 14, and a through groove 15 adapted to the top of the conveyor belt 2 is provided above. These components help stabilize the fiber felt's transport and ensure that it is not damaged during transport. Finally, the rotating roller 12 near the antistatic box 17 is sloped downwards, which helps to smoothly transport the dried fiber felt to the next process, improving production efficiency.

[0025] Furthermore, in the above scheme, such as Figures 5 to 7As shown, one side of the extrusion roller 21 is aligned with the conveyor belt 2, and a slide rail 22 is fixedly installed above the other side. Two sliders 23 are slidably arranged above the slide rail 22, and two movable baffles 24 are respectively installed at one end of the two sliders 23. A lead screw 25 with two opposite threaded sections is rotatably installed on one side of the slide rail 22, and the lead screw 25 is threadedly connected to the two movable baffles 24 respectively. A pressure roller 26 that abuts against the glass fiber mat is fixedly installed in the middle of the slide rail 22. The cutting module includes a fixed rod 28 fixedly installed on the discharge assembly 19 and a sliding block 29 slidably sleeved on the fixed rod 28. A cylinder 30 is provided on one side of the sliding block 29, and the bottom of the cylinder 30 extends and retracts. A cutter 31 is provided at one end of the discharge assembly 19. An inclined guide plate 20 is provided on one side of the discharge assembly 19 near the conveyor belt 2. The other end of the guide plate 20 is aligned with the middle of the extrusion roller 21. When the conveyor belt 2 delivers the dried glass fiber mat to the discharge assembly 19, it enters the extrusion roller 21 under the guidance of the guide plate 20. The glass fiber mat is first compressed by the extrusion roller 21, making it more compact and increasing the material's density and stability. This helps maintain the stability of its shape and performance during subsequent processing and use. After compression, the glass fibers are corrected by two movable baffles 24 at the rear to ensure accurate positioning in subsequent processing. When the movable baffle 24 is moved, the screw 25 is rotated to move the two movable baffles 24 away from or closer to each other. During the movement of the two movable baffles 24 away from or closer to each other, the slider 23 on one side slides on the slide rail 22 for positioning, making it more stable. During the correction or guidance process, the pressure roller 26 can effectively press the glass fiber mat against the movable baffle 24, which can help prevent the material from shifting during processing, improve the processing accuracy and consistency of the product, and accurately enter the tension roller 27 at the rear. The tension roller 27 and the discharge guide roller 32 are used to tension the discharge roll of the glass fiber mat. The tension roller 27 can accurately press the glass fiber mat into the tension roller 27 at the rear. Tensing the fiber felt helps maintain a certain tension during the winding process, preventing material loosening or wrinkling, and ensuring the neatness and compactness of the winding. A cutting module is set between the tensioning roller 27 and the discharge guide roller 32 to cut the glass fiber felt before winding. This facilitates subsequent storage, transportation and use, and also helps improve production efficiency and product quality. When cutting is required, the sliding block 29 on the movable fixing rod 28 drives the cutter 31 to move to the required cutting width. At this time, the cylinder 30 pushes the cutter 31 downward to cut the glass fiber felt. When cutting is not required, the cutter 31 can simply be retracted.

[0026] Although embodiments of the 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 invention, the scope of which is defined by the appended claims and their equivalents.
