Description

Technical Field

[0001] The invention belongs to the technical field of carbon fiber material processing and recycling, and in particular relates to a recycling device for carbon fiber material processing. Background Art

[0002] Carbon fiber is a high-strength and high-modulus fiber with a carbon content of more than 90%. It has the characteristics of high temperature resistance, friction resistance, electrical conductivity, thermal conductivity and corrosion resistance. This material not only has the characteristics of low density and high strength, but also exhibits excellent physical and chemical properties, such as high temperature resistance, high chemical stability, fatigue resistance, wear resistance, etc. Carbon fiber has a small specific gravity, so it has a high specific strength and specific modulus, which makes it widely used in many fields. A large amount of waste will be generated in the production and processing of carbon fiber. In order to avoid the waste of carbon fiber, these carbon fiber wastes need to be recycled.

[0003] In the Chinese patent with publication number CN113799296A, a tailing recovery device for carbon fiber material processing is mentioned. By providing a pull-out structure, the storage tank is pulled out by the sliding connection between the slider and the slide slot, which solves the problem that the large friction generated by the direct contact between the bottom of the storage tank and the recovery box affects the pulling effect. By reducing the friction, the convenience of pulling out the storage tank is improved, and the work of taking out the material inside the storage tank is facilitated;

[0004] In the above-mentioned tail material recovery device for carbon fiber processing in the prior art, when crushing the carbon fiber material, the crushed carbon fiber is easy to get stuck on the outside of the crushing roller. As the number increases, it is easy to affect the crushing effect of the crushing roller. In addition, the crushed carbon fiber material fails to be screened, resulting in excessive resin being mixed into the carbon fiber after crushing, which requires further processing, increasing the process and reducing work efficiency. For this reason, we propose a recovery device for carbon fiber material processing. Summary of the invention

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Reference Figure 1-Figure 6 As shown, the present invention provides a recovery device for carbon fiber material processing, comprising:

[0033] A conveyor frame 1, two conveyor belts rotating in opposite directions are arranged inside the conveyor frame 1, a shell 6 for crushing carbon fiber materials is arranged above the conveyor frame 1, and four supporting columns 2 distributed in a rectangular shape are fixedly connected to the bottom of the conveyor frame 1;

[0034] In addition, an L-shaped plate 4 is fixedly connected to the top of the conveying frame 1 , and the L-shaped plate 4 is fixedly connected to the outside of the outer shell 6 , and the top of the outer shell 6 is arranged in a trumpet shape.

[0035] A crushing mechanism 5, which is arranged inside the shell 6 and is used to crush the carbon fiber material entering the shell 6;

[0036] The screening mechanism 3 is arranged at the bottom of the shell 6 and located above the conveying frame 1, and is used for separating the carbon fiber and the resin in the crushed carbon fiber material.

[0037] In a further embodiment, referring to Figure 3 and Figure 5 The crushing mechanism 5 includes crushing rollers 504, which are symmetrically arranged on the inner side of the shell 6. The outer side of the shell 6 is fixedly connected to a motor frame 503, which is used to fix and support the drive motor 502. The inner side of the motor frame 503 is fixedly connected to the drive motor 502, and the drive motor 502 is installed with an output shaft. The two crushing rollers 504 are movably connected to the inner side of the shell 6 through bearings. The front ends of the two crushing rollers 504 penetrate the front side of the shell 6 and extend to the outside of the shell 6. The outer side of the crushing rollers 504 is fixedly connected to an annular shaft with equal spacing. The output shaft of the driving motor 502 is fixedly connected to the front end of one of the crushing rollers 504 through a coupling. The driving motor 502 drives one of the crushing rollers 504 to rotate through the output shaft and the coupling to provide power for the operation of the crushing roller 504. The outer sides of the two crushing rollers 504 are fixedly connected with gears 501. The opposite surfaces of the two gears 501 are meshed with each other. With the cooperation of the two gears 501, when one of the crushing rollers 504 rotates, the other crushing roller 504 can rotate in the opposite direction to crush the carbon fiber material.

[0038] In this embodiment, the driving motor 502 drives one of the crushing rollers 504 to rotate through the output shaft and the coupling. Under the action of the gear 501, the two crushing rollers 504 rotate in opposite directions, the carbon fiber material is crushed, and the carbon fiber and resin in the carbon fiber material are separated.

[0039] In a further embodiment, referring to Figure 6 Two symmetrically distributed oblique bars 506 are fixedly connected to the inner side of the shell 6, and cleaning teeth 507 that are densely distributed in a straight line and at equal intervals are fixedly connected to the outer side of the oblique bars 506. The cleaning teeth 507 are used to clean the crushing teeth 505 on the crushing roller 504 to prevent the crushed carbon fiber from being stuck between the two cleaning teeth 507, thereby affecting the subsequent crushing of the carbon fiber material. The cleaning teeth 507 are located between two adjacent groups of crushing teeth 505, and the oblique bars 506 are set to be U-shaped. The U-shaped setting facilitates the cleaned carbon fiber to pass through the inner side of the U-shaped oblique bars 506 to enter the screen 302 below, avoiding too much staying on the top of the oblique bars 506.

[0040] In this embodiment, the cleaning teeth 507 clean the carbon fibers between the crushing teeth 505 on the crushing roller 504 to prevent excessive carbon fibers from being stuck on the crushing roller 504, thereby ensuring the crushing effect of the carbon fiber material.

[0041] In a further embodiment, referring to Figure 1-Figure 3 The screening mechanism 3 includes a screen 302, which is arranged at the bottom of the shell 6 and above the conveyor frame 1. The screen 302 is arranged between the shell 6 and the conveyor frame 1 in an inclined state. The screen 302 is inclined with the left side higher and the right side lower, so that the resin powder in the crushed carbon fiber material enters the conveyor belt below, and the carbon fiber enters another conveyor belt, and is transported separately to facilitate subsequent recovery.

[0042] In this embodiment, the screen 302 screens the carbon fibers and resin powder in the crushed carbon fiber material, so as to facilitate the subsequent recycling of the carbon fibers.

[0043] In a further embodiment, referring to Figure 3-Figure 4The outer side of the screen 302 is fixedly connected to two symmetrically distributed connecting blocks 306, and the bottom of the connecting block 306 is fixedly connected to a spring 301, which can reset the pressed connecting block 306 and cause it to shake, so as to screen the crushed carbon fiber material. The inner side of the shell 6 is movably connected to a transmission rod 307 extending to the outside through a bearing, and the outer side of the transmission rod 307 is fixedly connected to a cam 303. The outer side of the cam 303 and the top of the connecting block 306 are both arranged in an arc shape, so that the cam 303 can easily push the connecting block 306 when it rotates. The connecting block 306 moves downward, and two symmetrically distributed fixed blocks 305 are fixedly connected to the outside of the shell 6. The screen 302 is movably connected to the opposite surfaces of the two fixed blocks 305 through a pin shaft. The spring 301 is fixedly connected to the top of the conveying frame 1. The front end of the transmission rod 307 is connected to the front end of one of the crushing rollers 504 through a pulley group 304. When one of the crushing rollers 504 rotates, the transmission rod 307 can be driven to rotate through the pulley group 304, thereby providing power for screening, reducing the use of motors, and increasing the linkage of various components in the device.

[0044] In this embodiment, while the crushing mechanism 5 is working, the transmission rod 307 is driven to rotate through the pulley group 304, so that the screen 302 is intermittently knocked and pushed through the cam 303, causing the screen 302 to shake, thereby achieving the purpose of screening and anti-blocking, and reducing the number of motors used and increasing the linkage of the device.

[0045] The working principle of the present invention is as follows:

[0046] The waste and tailings generated during the processing of the carbon fiber material enter the housing 6 through the trumpet-shaped feed port set on the top of the housing 6, and the output shaft of the driving motor 502 drives one of the crushing rollers 504 to rotate through the coupling, and the two crushing rollers rotate in opposite directions under the action of the gear 501, and the entering carbon fiber material is crushed by the crushing teeth 505;

[0047] When the crushing roller 504 rotates, the cleaning teeth 507 on the outside of the oblique strips 506 clean the carbon fiber material stuck between the crushing teeth 505 on the outside of the crushing roller 504, and the cleaned carbon fiber and the crushed carbon fiber fall onto the screen 302 below;

[0048] The rotation of the crushing roller 504 drives the transmission rod 307 to rotate through the pulley group 304, and the rotation of the transmission rod 307 drives the cam 303 to rotate. The rotation of the cam 303 intermittently knocks and pushes the connecting block 306 to move downward, and the screen 302 is shaken under the action of the spring 301 to screen the crushed carbon fiber and resin powder. The screened resin powder enters the left conveyor belt under the screen 302, and the carbon fiber on the screen 302 enters the right conveyor belt under the action of shaking. A collection container is placed under the conveyor belt to collect the carbon fiber and resin powder respectively, thereby completing the recycling of carbon fiber materials.

[0049] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
