Description

Technical Field

[0001] This invention relates to the field of material recycling technology, and more specifically, to a composite fiber material recycling and feeding device. Background Technology

[0002] The composite fiber material recycling and feeding device is a specialized automated equipment used in composite fiber material recycling and reuse production lines to stably convey, quantitatively feed, and continuously feed crushed and sorted composite fiber materials. It can achieve a smooth transition of materials in subsequent processes and improve the production efficiency of the composite fiber recycling process.

[0003] During the feeding process of composite fiber materials, since the composite fiber materials are mostly slender, soft, easily entangled, and rough fibrous materials, the fibers will interweave, hook, and overlap each other during the hopper's descent. Under the combined action of friction on the hopper's sidewall and its own weight, a stable arched support structure is formed, causing the material to suspend in the air and not discharge, resulting in bridging, jamming, and other phenomena. At the same time, the fibers have high elasticity and poor flowability, making it difficult for them to collapse on their own under gravity like granular materials. This can easily cause feeding interruptions and uneven discharge, seriously affecting the continuous and stable operation of the recycling production line. Summary of the Invention

[0004] In view of the problems existing in the prior art, the purpose of this invention is to provide a composite fiber material recycling and feeding device to solve the problem that composite fiber materials are prone to forming a stable arched support structure, thereby causing feeding interruption and uneven discharge.

[0005] To solve the above problems, the present invention adopts the following technical solution:

[0006] A composite fiber material recycling and feeding device includes a feeding bin, a feeding auger rotatably connected inside the feeding bin, a first motor fixedly connected to the left end of the feeding bin, the output shaft of the first motor fixedly connected to the left end of the feeding auger, and a clearing mechanism disposed at the top of the feeding bin. The clearing mechanism includes a compression conveying pipe connected to the top of the feeding bin, a feeding cylinder connected to the top of the compression conveying pipe, a peristaltic tube connected to the top of the feeding cylinder, the peristaltic tube being made of flexible rubber, a connecting clamp fixedly connected to the top of the peristaltic tube for connecting to an external feeding device, a support frame fixedly connected to the top of the feeding cylinder, a fourth motor fixedly connected to the surface of the support frame, a rotating frame fixedly connected to the output shaft of the fourth motor, and two push shafts rotatably connected to the surface of the rotating frame.

[0007] Furthermore, a connecting shaft is rotatably connected inside the feeding cylinder, a compression plate is fixedly connected to the surface of the connecting shaft, a plurality of pushing claws are fixedly connected to the edge of the compression plate, a bracket is fixedly connected to the top of the feeding bin, a second motor is fixedly connected to the top of the bracket, a connecting shaft is fixedly connected to the output shaft of the second motor, and the left end of the connecting shaft is fixedly connected to the right end of the connecting shaft.

[0008] Furthermore, a cutting groove is provided on the surface of the connecting shaft, and a connecting rod is inserted inside the feeding cylinder. A cutting blade that is compatible with the inside of the cutting groove is fixedly connected to the left end of the connecting rod.

[0009] Furthermore, a connecting block is fixedly sleeved on the surface of the connecting shaft, the connecting rod slides through the inside of the connecting block, a screw is threaded into the right end of the connecting rod, a driven gear is fixedly connected to the right end of the screw, a connecting frame is fixedly connected to the surface of the connecting shaft, a third motor is fixedly connected to the surface of the connecting frame, and a driving gear is fixedly connected to the output shaft of the third motor, the driving gear meshing with the driven gear.

[0010] Furthermore, it also includes a discharge mechanism, which is located at the right end of the feeding bin. The discharge mechanism includes a crushing bin that is connected to the right end of the feeding bin. A fifth motor is fixedly connected to the surface of the crushing bin, and a dispersing disc is fixedly connected to the output shaft of the fifth motor.

[0011] Furthermore, a partition is fixedly connected inside the crushing chamber, a baffle is fixedly connected inside the crushing chamber, and a guide ramp is fixedly connected to the top of the baffle.

[0012] Furthermore, the bottom end of the crushing chamber is connected to a discharge chamber. Two guide sleeves are fixedly inserted inside the left end of the discharge chamber. A first push-pull rod and a second push-pull rod are respectively inserted inside the two guide sleeves. Multiple suspension blocks are fixedly connected to the surfaces of the first push-pull rod and the second push-pull rod. A push plate is rotatably connected between the two suspension blocks.

[0013] Furthermore, all of the aforementioned push plates are inclined.

[0014] Furthermore, a sixth motor is fixedly connected to the left end of the discharge chamber, and a second drive arm is fixedly connected to the output shaft of the sixth motor. A first drive arm is rotatably connected to the right end of the second drive arm, and the right end of the first drive arm is rotatably connected to the left end of the first push-pull rod. The first push-pull rod, the first drive arm, and the second drive arm together form a reciprocating drive assembly.

[0015] Furthermore, a connecting rod is fixedly connected to the left end between the first push-pull rod and the second push-pull rod.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] (1) In the process of conveying composite fiber material, the composite fiber material enters the peristaltic tube. The fourth motor drives the rotating frame and the push shaft to rotate. The push shaft can squeeze the peristaltic tube to narrow it. After the push shaft is released, the peristaltic tube rebounds and returns to its original state. This process can be repeated to clear the blockage of composite fiber material and prevent bridging, cross-linking, and jamming of composite fiber material.

[0018] (2) In this scheme, the composite fiber material can be pushed down and squeezed during the rotation of the compression plate. The composite fiber material becomes denser when squeezed in the compression conveying pipe, which can make it more stable during the conveying process and prevent the fallen fiber from being loose and uneven in density, which would cause uneven force on the subsequent recycling host and cause violent fluctuations.

[0019] (3) This solution can drive the screw to rotate through the third motor, which can drive the connecting rod and the cutting blade to move along the cutting groove, cut the composite fiber material wrapped on the connecting shaft, and make the composite fiber material fall off, so as to prevent the composite fiber material from being wrapped on the connecting shaft and affecting its normal operation.

[0020] (4) When the composite fiber material comes into contact with the dispersion disc, the composite fiber material will be broken down and crushed. Then, by moving the pusher plate back and forth, the pusher plate can sweep across the surface of the composite fiber material, making the thickness of the composite fiber material more uniform, further reducing the fluctuation caused by uneven force on the subsequent recycling host, and pushing the composite fiber material out of the discharge chamber.

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Please see Figures 1-6A composite fiber material recycling and feeding device includes a feeding bin 1, with a feeding auger 3 rotatably connected inside the feeding bin 1. A first motor 2 is fixedly connected to the left end of the feeding bin 1, and the output shaft of the first motor 2 is fixedly connected to the left end of the feeding auger 3. The device also includes a clearing mechanism located at the top of the feeding bin 1. The clearing mechanism includes a compression conveying pipe 401 connected to the top of the feeding bin 1, and a feeding cylinder 402 connected to the top of the compression conveying pipe 401. The top end of the feeding cylinder 402 is connected to a peristaltic tube 405, which is made of flexible rubber. The top end of the peristaltic tube 405 is fixedly connected to a connecting clamp 407, which is used to connect to an external feeding device. The top end of the feeding cylinder 402 is fixedly connected to a support frame 423. The surface of the support frame 423 is fixedly connected to a fourth motor 420. The output shaft of the fourth motor 420 is fixedly connected to a rotating frame 421. The surface of the rotating frame 421 is rotatably connected to two push shafts 422.

[0036] The feeding cylinder 402 is rotatably connected to a connecting shaft 410. A compression plate 406 is fixedly connected to the surface of the connecting shaft 410. Multiple pushing claws 408 are fixedly connected to the edge of the compression plate 406. A bracket 403 is fixedly connected to the top of the feeding bin 1. A second motor 404 is fixedly connected to the top of the bracket 403. A connecting shaft 413 is fixedly connected to the output shaft of the second motor 404. The left end of the connecting shaft 413 is fixedly connected to the right end of the connecting shaft 410. A cutting groove 417 is formed on the surface of the connecting shaft 410. A connecting rod 409 is inserted into the inside of the feeding cylinder 402. A cutting blade 416 that matches the inside of the cutting groove 417 is fixedly connected to the left end of the connecting rod 409.

[0037] The connecting shaft 413 has a connecting block 411 fixedly sleeved on its surface. The connecting rod 409 slides through the connecting block 411. The right end of the connecting rod 409 has a screw 412 threadedly inserted inside. The right end of the screw 412 is fixedly connected to a driven gear 418. The connecting shaft 413 has a connecting frame 415 fixedly connected to its surface. The connecting frame 415 has a third motor 414 fixedly connected to its surface. The output shaft of the third motor 414 is fixedly connected to a driving gear 419, which meshes with the driven gear 418.

[0038] By adopting the above technical solution, during the conveying process of composite fiber material, the composite fiber material enters the peristaltic tube 405. If the composite fiber material becomes blocked in the peristaltic tube 405, the fourth motor 420 drives the rotating frame 421 to rotate, which in turn drives the push shaft 422 to rotate. The push shaft 422 can squeeze the peristaltic tube 405 to narrow it. Then the push shaft 422 releases the peristaltic tube 405 and springs back to its original state. This process can be repeated to clear the blockage of the composite fiber material.

[0039] As the composite fiber material continues to move downwards, the second motor 404 drives the connecting shaft 413 to rotate, which in turn drives the compression plate 406 to rotate. During the rotation of the compression plate 406, the composite fiber material can be pushed and squeezed downwards. Since the compression conveying pipe 401 is relatively narrow, the composite fiber material is squeezed and becomes dense in the compression conveying pipe. Then it enters the compression conveying pipe 401. Because the composite fiber material is squeezed, the density of the compressed composite fiber material is more uniform during the conveying process, which makes it more stable during the conveying process and prevents the fallen fibers from being fluffy and having uneven density, which would cause uneven force on the subsequent recycling host and cause violent fluctuations.

[0040] During the rotation of the connecting shaft 413 and the connecting rotating shaft 410 driven by the second motor 404, the pushing claw 408 on the compression plate 406 can also be rotated. This pushing claw 408 moves the composite fiber material downwards, further reducing the probability of blockage. Furthermore, the pushing claw 408 is a short claw, making it difficult for the composite fiber material to become entangled. When the second motor 404 drives the connecting shaft 413 to rotate, it can also simultaneously drive the third motor 414 to rotate. The third motor 414 is powered via a conductive slip ring, a common technique in existing technology, and will not be elaborated upon here. The third motor 414 drives the driving gear 419 and the driven gear 418 to rotate, which in turn drives the screw 412 to rotate. This causes the connecting rod 409 and the cutting blade 416 to move along the cutting groove 417, cutting off the composite fiber material entangled on the connecting rotating shaft 410 and causing it to fall off.

[0041] like Figure 7 , Figure 8 and Figure 9As shown, it also includes a discharge mechanism, which is located at the right end of the feeding bin 1. The discharge mechanism includes a crushing bin 501 connected to the right end of the feeding bin 1. A fifth motor 504 is fixedly connected to the surface of the crushing bin 501. A dispersing disc 503 is fixedly connected to the output shaft of the fifth motor 504. A partition 506 is fixedly connected inside the crushing bin 501. A baffle 505 is fixedly connected inside the crushing bin 501. A guide inclined plate 507 is fixedly connected to the top of the baffle 505. The composite fiber material can be moved out of the dispersing disc 503 by the cooperation of the inclined baffle 505 and the guide inclined plate 507.

[0042] The bottom end of the crushing chamber 501 is connected to the discharge chamber 502. Two guide sleeves 511 are fixedly inserted inside the left end of the discharge chamber 502. A first push-pull rod 508 and a second push-pull rod 516 are respectively inserted inside the two guide sleeves 511. Multiple suspension blocks 515 are fixedly connected to the surfaces of both the first push-pull rod 508 and the second push-pull rod 516. Push plates 514 are rotatably connected between two corresponding suspension blocks 515. The multiple push plates 514 are all inclined. The discharge chamber 502... A sixth motor 509 is fixedly connected to the left end. The output shaft of the sixth motor 509 is fixedly connected to a second drive arm 513. The right end of the second drive arm 513 is rotatably connected to a first drive arm 512. The right end of the first drive arm 512 is rotatably connected to the left end of the first push-pull rod 508. The first push-pull rod 508, the first drive arm 512, and the second drive arm 513 form a reciprocating drive assembly. A connecting rod 510 is fixedly connected to the left end between the first push-pull rod 508 and the second push-pull rod 516.

[0043] By adopting the above technical solution, the compressed and compacted composite fiber material enters the feeding hopper 1. Then, the first motor 2 drives the feeding auger 3 to rotate, conveying the composite fiber material to the crushing hopper 501, where it falls onto the dispersing disc 503. At this time, the fifth motor 504 drives the dispersing disc 503 to rotate at high speed. When the composite fiber material comes into contact with the dispersing disc 503, it is broken up and crushed. During this process, the output of the composite fiber material remains constant, maintaining its bulk density within a small range. The composite fiber material then falls into the discharge hopper 502. Then, the sixth motor 509 provides power to drive the reciprocating drive assembly consisting of the first push-pull rod 508, the first drive arm 512, and the second drive arm 513. This drives the first push-pull rod 508 and the second push-pull rod 516 to move back and forth, thereby driving the inclined push plate 514 to move back and forth. When the push plate 514 moves to the right, it can push the composite fiber material to the right. When the push plate 514 moves to the left, it can slide across the surface of the composite fiber material, making the thickness of the composite fiber material more uniform and further reducing the fluctuations caused by uneven force on the subsequent recycling host.

[0044] Instructions for use: First, the composite fiber material is introduced into the peristaltic tube 405;

[0045] Subsequently, the fourth motor 420 drives the rotating frame 421 to rotate, which in turn drives the push shaft 422 to reciprocate to squeeze and release the peristaltic tube 405. The peristaltic tube 405 is used to unblock the composite fiber material.

[0046] Next, after the composite fiber material is compressed, compacted, and conveyed, it continues to move downward. The second motor 404 is started to drive the connecting shaft 413 to rotate, which drives the compression plate 406 to push and compress the composite fiber material downward. The composite fiber material is compacted in the narrow compression conveying tube 401, making the density more uniform and ensuring the stability of subsequent conveying.

[0047] Meanwhile, the pushing claw 408 on the compression plate 406 rotates with the shaft, assisting in moving the composite fiber material downward, reducing the probability of blockage, and the short claw design can prevent the composite fiber material from getting tangled.

[0048] At the same time, while the second motor 404 drives the connecting shaft 413 to rotate, it synchronously drives the third motor 414 to drive the screw 412 to rotate, which in turn drives the connecting rod 409 and the cutting blade 416 to move along the cutting groove 417, cutting the composite fiber material wrapped on the connecting shaft 410 and causing the composite fiber material to fall off.

[0049] Next, the composite fiber material enters the feeding bin 1, and the first motor 2 drives the feeding auger 3 to rotate, quantitatively conveying the composite fiber material to the crushing bin 501 and dropping it onto the dispersing disc 503;

[0050] Subsequently, the fifth motor 504 drives the dispersing disc 503 to rotate at high speed. The composite fiber material is broken up and crushed after contacting the dispersing disc 503, and the output of the composite fiber material is kept constant throughout the process, so that the bulk density is controlled within a small range.

[0051] Subsequently, the composite fiber material falls into the discharge chamber 502;

[0052] Finally, the sixth motor 509 drives the inclined push plate 514 to scrape the thickness of the composite fiber material evenly and push the composite fiber material out of the discharge chamber 502.

[0053] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concepts, should be covered within the scope of protection of the present invention.
