Description

Technical Field

[0001] This utility model relates to the field of resource recycling technology, and in particular to a system for recycling, crushing and reusing carbon fiber prepreg scraps. Background Technology

[0002] Carbon fiber prepreg scraps are waste materials generated during the cutting and molding processes of carbon fiber prepregs, consisting of carbon fibers, resin, and other additives. Crushing and recycling equipment is used to recycle these scraps because their initial form is irregular, and the carbon fibers and resin are tightly bound together. Physical crushing is necessary to initially separate or refine the material, while precisely controlling the particle size. The function of the crushing and recycling equipment is to break the scraps into specific particle sizes, improving the uniformity and applicability of the recycled material, promoting the separation or dispersion of carbon fibers and resin, and providing basic raw materials for subsequent preparation of recycled composite materials, pyrolysis recovery of resin, or reuse of pure carbon fibers. This achieves resource recycling, reduces production costs, and minimizes environmental pollution.

[0003] A typical carbon fiber prepreg scrap recycling and reuse system consists of a feeding device, a crushing assembly, a screening device, a separation assembly, and a collection and storage unit. The feeding device transports the scrap to the crushing assembly, where it breaks it into smaller particles through shearing and impact. The screening device filters the crushed material by particle size, returning any substandard material to the crushing assembly for reprocessing. The separation assembly uses physical or chemical methods to separate the carbon fiber from the resin. The collection and storage unit stores the processed recycled material and is also equipped with environmentally friendly auxiliary equipment such as dust removal and purification systems to ensure a clean and safe operating environment.

[0004] In existing technologies, the screen plates of some carbon fiber prepreg scrap recycling and crushing systems become clogged with excessively large scraps after long-term use, which leads to a significant reduction in screening efficiency, slower material processing speed, and decreased equipment capacity. Therefore, a carbon fiber prepreg scrap recycling and crushing system is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a carbon fiber prepreg scrap recycling and crushing system, which aims to improve the problem in the prior art where excessive scrap will clog the screen holes after long-term use, resulting in a significant reduction in screening efficiency, slower material processing speed, and decreased equipment capacity.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A carbon fiber prepreg scrap recycling and crushing system includes a housing. A rotating rod is rotatably connected to the rear side of the housing. An upper inner column is fixedly connected to the outside of the rotating rod. A motor is fixedly connected to the rear side of the rotating rod. A gear is fixedly connected to the outside of the rotating rod. A belt is fitted around the outside of the upper inner column. Rotating rods are rotatably connected to both the front and rear sides of the housing. A lower inner column is fixedly connected to the outside of the rotating rod. A rotating disk is fixedly connected to the front side of the rotating rod. A moving plate is rotatably connected to the front side of the rotating disk. A screen plate is fixedly connected to the top of the moving plate. Multiple springs are fixedly connected to the top of the screen plate. A discharge assembly for automatic material discharge is fixedly connected to the bottom of the housing.

[0008] As a further description of the above technical solution:

[0009] The discharge assembly includes a bottom shell, the top of which is fixedly connected to the bottom of the outer shell. Two guide plates are fixedly connected to the inner wall of the bottom shell. A connecting plate is slidably connected to one of the adjacent sides of the two guide plates. A force-bearing plate is fixedly connected to one of the adjacent sides of the two connecting plates.

[0010] As a further description of the above technical solution:

[0011] The top of the outer shell is fixedly connected to a feed pipe, and the outer side of the lower inner column is sleeved inside the belt.

[0012] As a further description of the above technical solution:

[0013] Rotating rod three is fixedly connected to the front side of rotating rod one, and a crushing roller is fixedly connected to the outside of rotating rod three. Protective shells are fixedly connected to the inner walls of the front and rear sides of the outer shell.

[0014] As a further description of the above technical solution:

[0015] The sieve plate is slidably connected to the inner wall of the outer shell, and a slot is provided on the top of the outer shell;

[0016] As a further description of the above technical solution:

[0017] The inner wall of the outer shell is fixedly connected to a fixing ring, and the top of the plurality of fixing rings is fixedly connected to the bottom of the fixing ring;

[0018] As a further description of the above technical solution:

[0019] A fixing block is fixedly connected to the inner wall of the outer shell, and the outer side of the movable plate is slidably connected to the inside of the fixing block;

[0020] As a further description of the above technical solution:

[0021] Both connecting plates are fixedly connected to a spring at their bottom, and the left side of the force-bearing plate is slidably connected to the left inner wall of the bottom shell.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the motor causes the first rotating rod to rotate, which in turn causes the upper inner column to rotate the second rotating rod under the action of the belt. This causes the rotating disk to move the moving plate up and down, which in turn causes the screen plate to vibrate up and down, thereby achieving vibration cleaning of the filter plate. In addition, it can prevent material from clogging the screen holes, ensure screening efficiency and continuity, thereby reducing the frequency of manual maintenance, improving the stability of equipment operation and reducing labor intensity.

[0024] 2. In this utility model, the filtered scraps, under the effect of accumulation, allow resin debris with too low density to enter the force plate, causing the force plate to be subjected to gravity, which causes the spring to squeeze, allowing the resin debris to enter the bottom shell, thereby achieving the discharge and separation of scraps. In addition, high-purity carbon fiber can be accurately recovered, thereby removing impurities such as resin to improve the reuse value. 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] Reference Figure 2 and Figure 3 This utility model provides an embodiment of a carbon fiber prepreg scrap recycling and crushing system, comprising a housing 1, which serves as the foundation of the entire device, protecting and stabilizing it. A rotating rod 3 is rotatably connected to the rear of the housing 1. An upper inner column 4 is fixedly connected to the outside of the rotating rod 3. A motor 2 is fixedly connected to the rear of the rotating rod 3, serving as the drive source for the vibration assembly, causing the rotating rod 3 to rotate. The upper inner column 4 rotates along with the rotating rod 3, ensuring stability. A gear 5 is fixedly connected to the outside of the rotating rod 3, receiving the rotational force from the rotating rod 3 and thus rotating. A belt 6 is fitted around the outside of the upper inner column 4. Rotating rods 8 are rotatably connected to both the front and rear sides of the housing 1. The lower inner column 7 is fixedly connected to the outside of the 8. The rotating rod 8 is fixedly connected to the front of the rotating disk 9. The rotating disk 9 is rotatably connected to the front of the rotating plate 10. The top of the rotating plate 10 is fixedly connected to the screen plate 19. The top of the screen plate 19 is fixedly connected to multiple springs 20. The belt 6 is a transmission component that transmits the rotational power of the upper inner column 4 to the lower inner column 7. When the lower inner column 7 rotates, the rotating rod 8 rotates along with it, causing the rotating disk 9 to rotate. This causes the moving plate 10 to move up and down when the rotating disk 9 rotates, causing the screen plate 19 to move up and down. This allows the springs 20 to receive the compression of the screen plate 19, thereby storing elasticity. The bottom of the outer casing 1 is fixedly connected to the discharge assembly for automatic material discharge.

[0033] Reference Figure 2 and Figure 4 The discharge assembly includes a bottom shell 12, the top of which is fixedly connected to the bottom of the outer shell 1. The bottom shell 12 is the foundation of the entire device, thus protecting the entire interior and ensuring its stability. Two guide plates 13 are fixedly connected to the inner wall of the bottom shell 12. A connecting plate 15 is slidably connected to the adjacent side of each of the two guide plates 13. A force-bearing plate 14 is fixedly connected to the adjacent side of each of the two connecting plates 15. The guide plates 13 allow the connecting plates 15 to move linearly, thereby allowing the force-bearing plate 14 to move linearly. The connecting plates 15 connect the guide plates 13 and the force-bearing plate 14. The force-bearing plate 14 receives the impact force from the impact plate and thus moves.

[0034] Reference Figures 1 to 3The top of the outer casing 1 is fixedly connected to a feed pipe 22, which allows scrap material to enter the outer casing 1 for filtration. The lower inner column 7 is sleeved inside the belt 6. The belt 6 receives the rotational force from the upper inner column 4, causing the lower inner column 7 to rotate. A rotating rod 3 is fixedly connected to the front side of the rotating rod 1 3. A crushing roller 23 is fixedly connected to the outside of the rotating rod 3 18. The rotating rod 3 18 receives the rotational force from the rotating rod 1 3, causing the crushing roller 23 to rotate and stabilize. Protective shells 17 are fixedly connected to the inner walls of the front and rear sides of the outer casing 1. The screen plate 19 is slidably connected to the inner wall of the outer casing 1. The protective shells 17 protect the internal gear 5 structure and stabilize it. A slot is opened at the top of the outer casing 1, which allows the feed pipe 22 to pass through. 2. Here, a fixing ring 21 is fixedly connected to the inner wall of the outer shell 1. The tops of multiple springs 20 are fixedly connected to the bottom of the fixing ring 21. The springs receive the pushing force of the filter plate, thereby storing elastic force in the fixing ring 21. A fixing block 11 is fixedly connected to the inner wall of the outer shell 1. The outer side of the moving plate 10 is slidably connected to the inside of the fixing block 11. The fixing block 11 guides the moving plate 10, allowing it to move linearly and stably up and down. The bottoms of the two connecting plates 15 are fixedly connected to springs 16. Springs 16 receive the pushing force of the connecting plates 15, thereby storing elastic force. The left side of the force plate 14 is slidably connected to the left inner wall of the bottom shell 12. The force plate 14 receives the gravity of the scrap material, thereby moving downward.

[0035] Working principle: Motor 2 causes rotating rod 3 to rotate, which in turn causes crushing roller 23 inside housing 1 to rotate. Under the action of upper inner column 4, belt 6 drives lower inner column 7 to rotate, which in turn causes rotating rod 8 to rotate, which in turn causes rotating disk 9 to rotate, which in turn causes moving plate 10 on the turntable to move up and down, which in turn causes screen plate 19 to move up and down, which causes spring 20 to squeeze, thus achieving vibration cleaning of the filter plate. In addition, it can prevent material from clogging the screen holes, ensure screening efficiency and continuity, thereby reducing the frequency of manual maintenance, improving equipment operation stability and reducing labor intensity.

[0036] After the filtered scraps are piled up, the density causes resin debris to continuously enter the pressure plate 14. Under the action of the resin debris, the pressure plate 14 is squeezed by the spring 16, thus causing the resin debris to enter the bottom shell 12. This achieves the separation of scraps from the output. In addition, high-purity carbon fiber can be accurately recovered, thereby removing impurities such as resin to improve the reuse value.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
