Description

Technical Field

[0001] This utility model belongs to the technical field of winding equipment, and particularly relates to an impregnation device and a carbon fiber winding equipment. Background Technology

[0002] In the field of composite material manufacturing, especially in the production of high-requirement products such as pressure vessels, pipelines, and aerospace components, carbon fiber winding technology is widely used due to its superior performance. One of the core steps of this technology is to impregnate reinforcing fibers (such as carbon fiber tows) with a resin matrix (resin) through an impregnation device to form pre-impregnated fiber bundles (prepreg), which are then wound onto a mandrel along a specific path. The quality of the impregnation process directly affects the performance of the final composite material, with precise and uniform control of the resin content (resin amount) being particularly critical. Insufficient resin content leads to poor fiber wetting, weak interlayer bonding, and high product porosity, severely affecting the product's mechanical properties and sealing performance; excessive resin content results in increased product weight, decreased performance in resin-rich areas, increased curing shrinkage stress, and unnecessary material waste.

[0003] Different wound products (such as pipes of different diameters, containers of different pressures, and different structural components) often have different requirements for resin content. Even for the same product, different winding layers (such as circumferential layers and spiral layers) or different functional areas (such as the cylinder body and end caps) may require different resin contents to achieve optimal performance. However, existing equipment generally uses multiple settings to control the amount of resin, and adjustments usually require machine shutdown, resulting in insufficient adaptability and flexibility of the equipment and affecting production efficiency. Utility Model Content

[0015] In summary, the beneficial effects of this application are as follows: This invention achieves dynamic control of the entire carbon fiber impregnation process by integrating a tension adjustment mechanism, an impregnation mechanism, an adhesive quantity adjustment mechanism, and a buffer rack. The tension adjustment mechanism ensures that the carbon fiber filaments maintain a certain tension as they pass through the impregnation mechanism, guaranteeing the integrity of the impregnation. The adhesive quantity adjustment mechanism adjusts the adhesive quantity of the impregnated carbon fiber filaments to meet process requirements. The buffer rack temporarily stores the carbon fiber filaments adjusted by the adhesive quantity adjustment mechanism, ensuring that changes in the diameter of the winding medium do not affect the tension of the carbon fiber filaments during winding, thus preventing a decrease in winding quality.

After passing through the impregnation wheel, the carbon fiber filaments come into contact with the adhesive, achieving impregnation. This invention, through modular design, enables differentiated and precise control of the resin content requirements for different products, such as pipes / containers, or different areas of the same product, such as the cylinder body / end, significantly improving equipment adaptability and process flexibility.

[0021] In this embodiment, the tension adjustment mechanism 3 includes a fixed base 31, a first connecting plate 32, a first optical axis 33, a second optical axis 34, and an adjusting spring 35.

The first connecting plate 32 is located at the end away from the impregnation mechanism 2. The second optical axis 34 is located at the end of the first connecting plate 32 near the impregnation mechanism 2. The U-shaped opening of the fixing seat 31 is also provided with a fixing cover 312. One end of the adjusting spring 35 is connected to the side wall of the fixing seat 31 away from the impregnation tank 2, and the other end is connected to the side wall of the first connecting plate 32 near the first optical axis 33.

[0022] The first support plate 11 is provided with a first support shaft 111, and the first support shaft 111 is provided with a first idler roller 112. The second support plate 12 is provided with a second support shaft 121 at the end away from the first idler roller 112, and the second support shaft 121 is provided with a second idler roller 122. The second support plate 12 is also provided with a glue hopper 25 and a glue quantity detection sensor 26. The glue quantity detection sensor 26 is used to detect the glue quantity in the glue storage tank 21. The second support plate 12 is also provided with a scraper shaft at the end near the tension adjustment mechanism 3. The scraper shaft is provided with a scraper 24. Several scrapers 24 are correspondingly arranged with the dip roller 23. The scrapers 24 can rotate synchronously with the scraper shaft. When the glue dipping is finished or the machine is stopped to replace the glue, the scraper shaft is rotated to make the scraper 24 contact the dip roller 23, so as to achieve the initial cleaning of the glue on the dip roller 23.

[0023] The mounting frame 1 is also provided with a third support plate 13 at one end near the buffer rack 5. The third support plates 13 are arranged in pairs along the width direction of the mounting frame 1. A first scraper 131, a second scraper 132 and a third scraper 133 are provided between the two pairs of third support plates 13. The first scraper 131, the second scraper 132 and the third scraper 133 are arranged parallel to each other along the width direction of the mounting frame 1.

[0024] The adhesive amount adjustment mechanism 4 is disposed on the two pairs of third support plates 13 and is located above the first scraper 131, the second scraper 132 and the third scraper 133. The adhesive amount adjustment mechanism includes an adjustment block 41, a second connecting plate 411, a third optical axis 42 and a fourth optical axis 43. The adjustment block 41 is provided with a height adjustment bolt. Both adjustment blocks 41 are connected to the two pairs of third support plates 13 respectively through the height adjustment bolt. The second connecting plate 411 is disposed on the adjustment block 41. The third optical axis 42 and the fourth optical axis 43 are disposed on the two pairs of second connecting plates 411. The third optical axis 42 is located between the first scraper 131 and the second scraper 132, and the fourth optical axis 43 is located between the second scraper 132 and the third scraper 133. The gap between the first scraper 131, the second scraper 132, and the third scraper 133 is greater than the shaft diameter of the third optical axis 42 and the fourth optical axis 43, thereby ensuring that the third optical axis 42 and the fourth optical axis 43 can pass through the gap between the first scraper 131 and the second scraper 132 and the gap between the second scraper 132 and the third scraper 133. The adjusting block 41, under the adjustment of the height adjusting bolt, can move up and down synchronously with the third optical axis 42 and the fourth optical axis 43 relative to the first scraper 131, the second scraper 132, and the third scraper 133. In the vertical direction, the top positions of the first scraper 131, the second scraper 132, and the third scraper 133 are all higher than the bottom positions of the third optical axis 42 and the fourth optical axis 43. When the carbon fiber filament 8 passes through the adhesive amount adjusting mechanism 4, it sequentially passes from the top of the first scraper 131, the bottom of the third optical axis 42, and the second scraper 132... The top, bottom of the fourth optical axis 43, and top of the third scraper 133 pass through the carbon fiber filament 8. The carbon fiber filament 8 forms a wave-shaped mechanism through contact with the first scraper 131, second scraper 132, and third scraper 133 via the third and fourth optical axes 42 and 43. Adjusting the adjusting bolts changes the relative distance between the third and fourth optical axes 42 and 43 and the three scrapers, allowing the scrapers to remove excess adhesive from the carbon fiber filament 8. Moving the optical axis downward increases the friction between the filament and the scraper, increasing the amount of adhesive removed and thus reducing the amount of adhesive on the filament. Moving the optical axis upward decreases the friction between the filament and the scraper, reducing the amount of adhesive removed and thus increasing the amount of adhesive on the filament. This controls the amount of adhesive on the carbon fiber filament 8, allowing for stepless adjustment of the adhesive amount without stopping the machine, meeting the differentiated needs of different layers. The adhesive removed by the scrapers flows into the adhesive storage tank 21, thus avoiding adhesive waste.

[0025] The buffer rack 5 is provided with a third support shaft 52 and a fourth support shaft 53. The axes of the third support shaft 52 and the fourth support shaft 53 are in the same horizontal plane as the axes of the first support shaft 111 and the second support shaft 121 and are arranged parallel to each other. The third support shaft 52 is close to the second support shaft 121. The third support shaft 52 and the fourth support shaft 53 are respectively provided with a third idler roller 521 and a fourth idler roller 531.

[0026] The buffer rack 5 is also equipped with a cylinder mounting seat 51. A cylinder 6 is mounted in the middle of the cylinder mounting seat 51, and guide shafts 511 are provided on both sides. The piston rod 61 of the cylinder 6 is connected to a third connecting plate 62 at the end away from the cylinder 6. The guide shafts 511 are connected to the third connecting plate 62 at the end away from the cylinder mounting seat 51. A U-shaped frame 63 is connected to the end of the third connecting plate 62 away from the cylinder 6. A fifth idler roller 64 is rotatably connected to the U-shaped frame 63. The idler roller 64 is positioned horizontally between the third idler roller 521 and the fourth idler roller 531, and vertically above the third idler roller 521 and the fourth idler roller 531. The number of the glue-impregnating rollers 23 is the same as the number of the first idler roller 112, the second idler roller 122, the third idler roller 521, the fourth idler roller 531, and the cylinder 6. The carbon fiber filaments 8 are sequentially fed to the winding station from the bottom of the third idler roller 521, the top of the fifth idler roller 64, and the bottom of the fourth idler roller 531 after passing through the glue amount adjustment mechanism 4.

[0027] Each set of first idler rollers 112, dipped rollers 23, second idler rollers 122, third idler rollers 521, fourth idler rollers 531, and fifth idler rollers 64, arranged parallel to each other along the length of the mounting frame 1, together with the corresponding cylinders 6, forms a dipped roller group. Several dipped roller groups are arranged along the width of the mounting frame 1. Each dipped roller group is provided with several carbon fiber filaments 8. After being dipped in resin, the carbon fiber filaments 8 on each dipped roller group are sent to the winding medium at different workstations for winding. A drive motor is connected to the rotating shaft 22. The drive motor is used to drive the rotating shaft 22 to drive the dipped rollers 23 to rotate. The cylinders 6 and the drive motor are electrically connected to the electrical control box 7 at the bottom of the mounting frame 1. A guide plate 14 is provided at the position opposite to the buffer frame 5 on the mounting frame 1. The guide plate 14 is provided with several sets of guide holes 141. The carbon fiber filaments 8 are sent to the tension adjustment mechanism 3 after passing through the guide holes 141.

[0028] This device integrates a tension adjustment mechanism 3, an impregnation mechanism 2, an adhesive quantity adjustment mechanism 4, and a buffer rack 5 to achieve dynamic control of the entire impregnation process of the carbon fiber filament 8. The tension adjustment mechanism 3 ensures that the carbon fiber filament 8 has a certain tension when passing through the impregnation mechanism 2, guaranteeing the integrity of the impregnation. The adhesive quantity adjustment mechanism 4 adjusts the adhesive quantity of the impregnated carbon fiber filament 8 to meet process requirements. The buffer rack 5 is used to temporarily store the carbon fiber filament 8 after adjustment by the adhesive quantity adjustment mechanism 4. A cylinder 6 ensures that the tension on the carbon fiber filament 8 is not affected by changes in the diameter of the winding medium during winding, thus preventing a decrease in winding quality. When the carbon fiber filament 8 passes through the impregnation mechanism 2, the impregnation wheel 23 rotates, and the adhesive in the adhesive storage tank 21 comes into contact with the outer surface of the impregnation wheel 23, thereby filling the outer surface of the impregnation wheel 23 with adhesive. After passing through the impregnation wheel 23, the carbon fiber filament 8 comes into contact with the adhesive, achieving the impregnation of the carbon fiber filament 8. This utility model achieves differentiated and precise control of resin content requirements for different products, such as pipes / containers, or different areas of the same product, such as the cylinder body / end, through modular design, significantly improving equipment adaptability and process flexibility.
