Description

Technical Field

[0001] This utility model relates to the field of carbon fiber recycling technology, specifically a roller pressing device for extracting carbon fibers from composite materials. Background Technology

[0002] Carbon fiber reinforced plastics (CFRP) are widely used in high-end manufacturing fields such as aerospace, automotive, wind power, and sporting goods due to their excellent strength-to-weight ratio and corrosion resistance. However, with the widespread use of CFRP, related waste and material recycling issues have become increasingly prominent. The recycling and reuse of CFRP is crucial for promoting sustainable development, but the recycling process for this type of material is relatively complex. Against this backdrop, CFRP crushing and extraction devices, as an emerging recycling equipment, aim to process waste CFRP through physical or chemical means to extract the carbon fibers for further recycling and reuse.

[0003] Carbon fibers are tightly bonded to the matrix material, making efficient separation difficult with conventional mechanical crushing or chemical dissolution methods. Physical crushing is a commonly used method for recycling carbon fiber composites, typically employing mechanical means to break the composite into small particles or powder. This process helps disrupt the structure of the matrix material, facilitating subsequent fiber separation. However, current equipment suffers from less than ideal crushing effects, uneven material distribution, low efficiency, and lack of adjustability. Therefore, this application proposes a roller pressing device for extracting carbon fibers from composite materials. Utility Model Content

[0004] The purpose of this invention is to provide a roller pressing device for extracting carbon fibers from composite materials, which can improve the crushing effect and crushing efficiency.

[0005] To achieve the above objectives, this utility model proposes the following technical solution: a roller pressing device for extracting carbon fibers from composite materials, comprising:

[0006] The frame and side panels together form the chassis.

[0007] A feed pipe is located at the top of the machine housing and is used to convey materials into the machine housing.

[0008] The first roller pressing layer, the second roller pressing layer, and the third roller pressing layer are arranged sequentially from top to bottom. The material entering from the feed pipe is crushed by passing through the first roller pressing layer, the second roller pressing layer, and the third roller pressing layer in sequence.

[0009] The auger and the receiving nozzle are arranged at the bottom of the third roller pressing layer. The bottom of the receiving nozzle is connected to the feed inlet of the auger through a pipe. The auger conveys the crushed material to the separation and extraction equipment.

[0010] Furthermore, in this utility model, the first roller pressing layer, the second roller pressing layer, and the third roller pressing layer all include a crushing mechanism and a material equalization mechanism, wherein the material equalization mechanism is used to evenly distribute the material on the crushing mechanism.

[0011] Furthermore, in this utility model, the material equalization mechanism includes two upper equalization plates, which are inclined and have a gap between them. The gap is used for material feeding and is located on the two rolling rollers of the crushing mechanism, thereby evenly distributing the material between the rolling rollers. Several evenly distributed vertical plates are fixedly connected to the upper equalization plates.

[0012] The material distribution mechanism also includes a lower filter collection plate, which is located at the bottom of the roller and has several through holes.

[0013] Furthermore, in this utility model, there are four lower filter collection plates, and the four lower filter collection plates are arranged at an angle.

[0014] Furthermore, in this utility model, the crushing mechanism includes a motor, a first rolling roller, and a second rolling roller. The motor drives the first rolling roller and the second rolling roller to rotate through a gearbox to perform the crushing operation.

[0015] Furthermore, in this utility model, the gearbox includes a first gear, a second gear, and a third gear. The motor drives the second and third gears to rotate through the first gear. The second and third gears are respectively fixedly connected to the first and second rolling rollers via connecting shafts. A slider is fixedly connected to the connecting shaft, and a movable plate is fixedly connected to the slider. A threaded rod is threadedly connected to the movable plate, and a rotating wheel is fixedly connected to the threaded rod.

[0027] Example 1

[0028] like Figure 1-4 As shown, a roller pressing device for extracting carbon fibers from composite materials includes a frame 1, a side plate 2, a feed pipe 3, a first roller pressing layer 4, a second roller pressing layer 5, a third roller pressing layer 6, an auger 7, and a receiving nozzle 8. The frame 1 and the side plate 2 form a housing. The feed pipe 3 is located at the top of the housing and is used to convey materials into the housing.

[0029] The first roller pressing layer 4, the second roller pressing layer 5, and the third roller pressing layer 6 are arranged sequentially from top to bottom. The material entering from the feed pipe 3 is crushed by passing through the first roller pressing layer 4, the second roller pressing layer 5, and the third roller pressing layer 6 in sequence.

[0030] The receiving nozzle 8 is located at the bottom of the third roller pressing layer 6. The bottom of the receiving nozzle 8 is connected to the feed port of the auger 7 through a pipe. The auger 7 uses the crushed material to transport to the separation and extraction equipment.

[0031] In this embodiment, the step-by-step design of the first roller pressing layer 4, the second roller pressing layer 5, and the third roller pressing layer 6 ensures that the material is gradually crushed, more effectively breaking larger pieces of carbon fiber composite material into smaller particles. Each roller pressing device can select a different crushing method according to the characteristics of the material, gradually reducing the particle size and improving crushing efficiency. The first roller pressing layer 4 is usually used for coarse crushing or preliminary crushing, which can quickly crush large pieces of material. The second roller pressing layer 5 further crushes the material crushed by the first roller pressing layer to a smaller particle size, suitable for fine crushing. The final fine crushing step of the third roller pressing layer 6 can make the crushed material reach the required smaller particle size or powder. The feed pipe 3 is located at the top of the machine box, allowing the material to enter the machine box smoothly by gravity or other conveying means, simplifying the material feeding process. The frame 1 and side plates 2 of the machine box form a closed working environment: this closed design helps to keep the inside of the equipment clean, avoids material splashing or leakage during the crushing process, and improves the safety and ease of operation of the equipment.

[0032] The material conveying system after crushing includes a receiving nozzle 8 and an auger 7. By setting the receiving nozzle 8 at the bottom of the third roller pressing layer 6, the crushed material is effectively collected and conveyed to the auger 7 through a pipeline. As a screw conveyor, the auger 7 can continuously and stably convey the crushed material to the subsequent separation and extraction equipment, avoiding the problems of material accumulation or blockage.

[0033] In operation, the material enters the casing through the feed pipe 3. Upon entering the casing, the material first enters the first roller press layer 4 for preliminary crushing. In this stage, larger pieces are broken down or cut into smaller particles. The second roller press layer 5 further crushes the material into smaller particles for the fine crushing stage. In the third roller press layer 6, the material is further ground into smaller powders or particles, preparing for subsequent separation and extraction processes. This carbon fiber composite material crushing and extraction device in this embodiment has advantages such as multi-stage crushing, a closed casing, graded collection, and efficient conveying. It can effectively improve the crushing efficiency and precision of carbon fiber composite materials, reduce material waste, and enhance the efficiency of subsequent extraction and separation processes. Layer-by-layer crushing ensures a balanced workload for each crushing system, thereby improving the equipment's service life and operational stability. Simultaneously, the use of an auger optimizes material conveying, improving the overall smoothness and reliability of the production process.

[0034] Example 2

[0035] like Figure 1-4 As shown in Example 1, in this embodiment, the first roller pressing layer 4, the second roller pressing layer 5, and the third roller pressing layer 6 all include a crushing mechanism and a material equalization mechanism. The material equalization mechanism is used to evenly distribute the material on the crushing mechanism. Each roller pressing layer is equipped with a material equalization mechanism, such as an upper material equalization plate and a lower filter collection plate. Through these material equalization mechanisms, the material can be evenly distributed on the rollers, avoiding uneven distribution of the material during the crushing process, thereby ensuring the consistency of the crushing effect and improving the working stability of the equipment.

[0036] In this embodiment, the material equalization mechanism includes two upper equalization plates 901, which are inclined and have a gap between them. The gap is used for material feeding and is located on the two rollers of the crushing mechanism, thereby evenly distributing the material between the rollers. Several evenly distributed vertical plates 902 are fixedly connected to the upper equalization plates 901.

[0037] The material distribution mechanism also includes a lower filter collection plate 906, which is located at the bottom of the roller. The lower filter collection plate 906 has several through holes 907. By using the lower filter collection plate 906 and multiple through holes 907, effective layered filtration and material collection are achieved, so that the material is evenly distributed on the upper distribution plate 901 of the next layer, avoiding excessive accumulation or blockage of material.

[0038] In this embodiment, there are four lower filter collection plates 906, which are arranged at an angle.

[0039] In this embodiment, the crushing mechanism includes a motor 903, a first rolling roller 904, and a second rolling roller 905. The motor 903 drives the first rolling roller 904 and the second rolling roller 905 to rotate through a gearbox to perform the crushing operation.

[0040] In this embodiment, the gearbox includes a first gear 908, a second gear 909, and a third gear 910. The motor 903 drives the second gear 909 and the third gear 910 to rotate via the first gear 908. The second gear 909 and the third gear 910 are fixedly connected to the first rolling roller 904 and the second rolling roller 905 via connecting shafts, respectively. The motor drives the rolling rollers to rotate through the gearbox, ensuring strong and stable power output. This system utilizes multi-stage gear transmission, effectively transmitting the motor's power to the rolling rollers, ensuring the continuity and stability of crushing, and reducing equipment malfunctions caused by insufficient power.

[0041] A slider 911 is fixedly connected to the connecting shaft, and a movable plate is fixedly connected to the slider 911. A threaded rod is threadedly connected to the movable plate, and a rotating wheel 912 is fixedly connected to the threaded rod. The rotation of the rotating wheel 912 drives the movable plate and the slider 911 to move, thereby adjusting the distance between the first roller 904 and the second roller 905. The distance between the rollers can be flexibly adjusted through the adjustment functions of the rotating wheel 912 and the threaded rod. This design allows users to precisely control the particle size and fineness of the pulverized material according to its properties or the required degree of pulverization, improving the adaptability of the equipment.

[0042] In operation, the material first enters the upper equalization plate 901 on the first roller pressing layer 4 through the feed pipe 3. Through the upper equalization plate 901, the material is evenly distributed between the two rollers for crushing. The motor 903 drives the first roller 904 and the second roller 905 to rotate via a gearbox for crushing. The crushed material falls onto four lower filter collection plates 906, which have several through holes 907. The material through these holes 907 is evenly distributed on the upper equalization plate 901 of the next layer, preventing excessive accumulation or blockage. Similarly, the material continues to be crushed on the second roller pressing layer 5 and the third roller pressing layer 6. The crushed material on the third roller pressing layer 6 falls onto the receiving nozzle 8, effectively collecting the crushed material and conveying it through a pipe to the auger 7. The auger 7, as a spiral conveyor, can continuously and stably transport the crushed material to the subsequent separation and extraction equipment, avoiding material accumulation or blockage.

[0043] This embodiment, with its multi-stage crushing, uniform material design, flexible adjustment, filtration and collection, and efficient transmission system, not only improves the precision and efficiency of material crushing but also ensures the stability and maintainability of the equipment. Its purpose is to provide an efficient, uniform, and stable crushing solution for the subsequent extraction process of carbon fiber composite materials, ultimately improving production efficiency and product quality.

[0044] All standard parts used in this application can be purchased from the market, and can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. The control method is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art and is common knowledge in the field. Since this application is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail in this application.

[0045] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Those skilled in the art to which this invention pertains can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of this invention shall be determined by the claims.
