[0002] Carbon fiber, also known as carbon fiber composite material, is a composite material made of organic polymers, nylon, epoxy resin and other matrix materials and carbonized fiber fibers.

[0003] Carbon fiber prepreg, also known as carbon fiber prepreg cloth, is a composite material made of carbon fiber yarn, epoxy resin, release paper and other materials through processes such as coating, hot pressing, cooling and lamination. The advantage of carbon fiber prepreg is that its strength can reach 6-12 times that of steel, its density is only one-fourth of steel, and it can be made into any shape according to the shape of the mold. It is easy to form and convenient to process.

[0024] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0025] The implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0026] Embodiment 1:

[0027] according to Figure 1-5 As shown, a heavy carbon fiber prepreg preparation device comprises a mounting plate 1 and an impregnation roller 2, wherein two mounting plates 1 are provided, and an impregnation roller 2 is rotatably connected between a pair of mounting plates 1;

[0028] It also includes a transverse axis 3, a cleaning structure and a quick-release structure, wherein the transverse axis 3 is arranged between a pair of the mounting plates 1, and the cleaning structure is arranged on the surface of the transverse axis 3;

[0029] The cleaning structure includes a collecting box 5, which is mounted on the surface of the horizontal axis 3. A feed port 11 is provided on the surface of the collecting box 5. A scraper 10 is provided in the feed port 11. The end of the scraper 10 away from the collecting box 5 is a free end and is attached to the surface of the impregnation roller 2. The quick-release mechanism includes a mounting block 7, which is fixed on the surface of the collecting box 5. The mounting block 7 is "L" shaped. A through groove 16 is provided on the surface of the horizontal axis 3. The mounting block 7 is slidably connected in the through groove 16. The surface of the horizontal axis 3 is slidably connected with an insertion shaft 9 through a spring. A socket is provided on the surface of the mounting block 7 relative to the insertion shaft 9.

[0030] During operation, when the prepreg is impregnated, the transverse axis 3 is installed between the two mounting plates 1, and then the collecting box 5 is installed on the surface of the transverse axis 3 through the quick-release mechanism, and the scraper 10 is made to fit the surface of the impregnation roller 2. When the impregnation roller 2 rotates, the impurities on the surface of the impregnation roller 2 are scraped off by the scraper 10, and at the same time, the impurities are guided by the arc scraper 10 to be introduced into the collecting box 5 through the feed port 11 for collection, so as to avoid the impurities repeatedly falling on the surface of the impregnation roller 2, thereby ensuring the cleanliness of the surface of the impregnation roller 2, and thus avoiding the problem of crushing the prepreg when the impregnation roller 2 squeezes and impregnates the prepreg, thereby ensuring the production yield of the prepreg. When the quick-release structure is in use, the plug-in axis 9 is moved away from the mounting block 7, so that the mounting block 7 is released from restriction, and the collecting box 5 can be quickly disassembled and cleaned.

[0031] A pair of surfaces of the mounting plates 1 are provided with a slide groove 4, the two ends of the transverse axis 3 are slidably connected in the slide groove 4, the surface of the end of the transverse axis 3 is slidably connected with a clamping shaft 17 through a spring, the side wall of the slide groove 4 is provided with a clamping groove relative to the clamping shaft 17, and the clamping groove is provided in plurality, the end of the clamping shaft 17 is an arc surface, the scraper 10 is rotatably connected in the collection box 5, one side of the scraper 10 is fixedly connected with a spring sheet 12, and the end of the spring sheet 12 away from the scraper 10 is fixedly connected to the surface of the collection box 5;

[0032] During operation, after the collection box 5 is used, the horizontal axis 3 is pressed downward, so that the horizontal axis 3 drives the clamping axis 17 to move in the chute 4 at the same time, and the clamping axis 17 is separated from the through slot 16. When the horizontal axis 3 moves to the limit position of the chute 4, the clamping axis 17 is clamped into the clamping slot below the chute 4 to limit the position. When the horizontal axis 3 slides downward, it will drive the collection box 5. At the same time, the collection box 5 drives the scraper 10 to separate from the impregnation roller 2. At this time, the spring piece 12 is reset, driving the scraper 10 to rotate, blocking the feed port 11, and closing it to prevent the internal impurities from flowing out when the collection box 5 is disassembled. When it is needed, the collection box 5 is close to the impregnation roller 2, and the scraper 10 is attached to the surface of the impregnation roller 2. The spring piece 12 can improve the adhesion of the scraper 10 to the surface of the impregnation roller 2, thereby improving the cleaning effect of the scraper 10.

[0033] The surface of the transverse axis 3 is slidably connected with a slider 13, and the surface of the slider 13 is fixedly connected with a vertical plate 14, and the vertical plate 14 is "L"-shaped. The surface of the short arm end of the vertical plate 14 is provided with an oblique angle, and the surface is fixedly connected with a positioning block 15, and the surface of the plug-in shaft 9 is fixedly connected with a connecting plate 8, and the surface of the connecting plate 8 is provided with a notch relative to the position of the positioning block 15, and the vertical plate 14 is in contact with the mounting block 7; during operation, the vertical plate 14 is moved in a direction close to the connecting plate 8, and the positioning block 15 is driven to move at the same time. When the oblique angle of the surface of the vertical plate 14 is in contact with the surface of the connecting plate 8, the oblique angle of its surface will squeeze the connecting plate 8 so that the connecting plate 8 moves upward, and at this time the vertical plate 14 continues to move, driving the positioning block 15 to fit into the positioning groove, positioning the connecting plate 8, and thus facilitating the installation of the collecting tank.

[0034] The surface of the transverse axis 3 is provided with a fixing groove 19, in which a push plate 18 is slidably connected by a spring, and a plug piece 21 is rotatably connected to the surface of the push plate 18 by a torsion spring. The plug piece 21 is made of rubber material, and a chamfer 20 is provided on the surface of the fixing groove 19. A fixing block 6 is fixedly connected to the surface of the collection box 5, and the fixing block 6 is installed in the fixing groove 19; during operation, when the collection box 5 drives the mounting block 7 to snap into the through groove 16, it will drive the fixing block 6 to squeeze the push plate 18, so that the push plate 18 moves into the fixing groove 19, and at the same time, the squeezing spring generates elastic force. When the plug shaft 9 is pulled out to release the limit, the spring resets, drives the push plate 18 to push the fixing block 6 out, and at the same time drives the plug piece 21 to move outward. When the plug piece 21 moves to the opening position of the fixing groove 19, due to the setting of the chamfer 20, the two plug pieces 21 will rotate in the direction away from each other, so that the opening presents a trumpet shape. By cooperating with the fixing block 6 through the plug piece 21, it can be achieved that the fixing block 6 is easy to install, and the stability of the collection box 5 after installation can also be improved.
