Description

Technical Field

[0001] This utility model is specifically a fiber composite material crushing and sorting diameter control conveying device. Background Technology

[0002] The crushing of fiber composite materials is a process that combines graded crushing with targeted impurity removal. The primary considerations are to avoid excessive fiber entanglement and ensure uniform particle size. The crushing process includes multiple processing steps, mainly a pretreatment step that uses a jaw crusher or shear crusher to crush the material into predetermined blocks, thereby reducing the pressure on subsequent crushing. Next comes the medium crushing process, which uses an impact crusher. High-speed rotating hammers strike the material, breaking the coarsely crushed lumps into particles of a predetermined size. Subsequent fine crushing processes follow, but because the size of the crushed particles is not entirely controllable, particle sizes still vary, resulting in a mixture of particles of different sizes. Although subsequent sorting and screening are performed, the effect is not precise enough; only passive sieving from largest to smallest is possible. Currently, in the process of sorting and breaking down fiber composite materials, there are issues such as uneven particle size distribution after crushing, insufficient control over the geometric dimensions of the fibers, and a lack of methods for rapid, unordered, or on-demand particle separation. Furthermore, for applications requiring high particle size precision, such as laboratory environments, there are no effective measures to actively control particle size screening according to predetermined requirements, nor are there standardized methods for particle size classification.

Detailed Implementation

[0016] 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.

[0017] Specific implementation method one: Combining Figures 1 to 9This embodiment describes a fiber composite material crushing and separation device using a diameter-controlled conveying system. The device includes a vibratory crushing mechanism 2 and a self-adjusting electromagnetic vibrator 6. The self-adjusting electromagnetic vibrator 6 is located on top of the vibratory crushing mechanism 2. The self-adjusting electromagnetic vibrator 6 includes a support plate 6-1, a first transverse transmission component 6-2, a third drive motor 6-6, an electromagnetic vibrator 6-8, a vibrating plate 6-9, a connecting frame 6-10, two second transverse transmission components 6-3, four vertical worm gears 6-4, and four sliding tables 6-5. The connecting frame 6-10 is fixedly connected to the top of the vibratory crushing mechanism 2. The first transverse transmission component 6-2 and the two second transverse transmission components 6-3 are horizontally arranged side-by-side within the connecting frame 6-10. The support plate 6-1 and the vibrating plate 6-9 are horizontally arranged from top to bottom within the connecting frame 6-10. A material channel 7 is formed between the bottom surface of the vibrating plate 6-9 and the top surface of the vibratory crushing mechanism 2. The electromagnetic vibrator 6-8 passes through the support plate 6-1 and the vibrating plate 6-9. Between the support plate 6-1 and the vibrating plate 6-9, four vertical worm gears 6-4 are arranged vertically side by side. Each second transverse transmission member 6-3 is equipped with two corresponding vertical worm gears 6-4, and each second transverse transmission member 6-3 meshes with its two corresponding vertical worm gears 6-4. The third drive motor 6-6 is fixedly connected to the outer wall of the connecting frame 6-10. One end of the first transverse transmission member 6-2 passes through the connecting frame 6-10 and is connected to the third drive motor 6-6. The other end of 2 is engaged with two second transverse transmission components 6-3 respectively; the lower end of each vertical worm 6-4 is set on the top surface of the vibrating plate 6-9, and the upper end of each vertical worm 6-4 passes through the support plate 6-1 and is connected to the top inner wall of the connecting frame 6-10. Each vertical worm 6-4 is provided with a corresponding slide 6-5, and each slide 6-5 is connected to the support plate 6-1. The slide 6-5 drives the support plate 6-1 to make reciprocating lifting and lowering movements along the length direction of the vertical worm 6-4.

[0018] In this embodiment, the first transverse transmission component 6-2 and the second transverse transmission component 6-3 have the same structure and working principle, differing only in their arrangement direction and position. The first transverse transmission component 6-2 is a meshing transmission structure composed of a worm gear 27 and a worm 26. The worm gear 27 is an existing toothed wheel body, which is mounted on the worm 26. The worm 26 meshes with the worm 26 in the adjacent second transverse transmission component 6-3 through the worm gear 27. Thus, the first transverse transmission component 6-2 is driven to rotate by the third drive motor 6-6. The meshing of the first transverse transmission component 6-2 and the second transverse transmission component 6-3 rotates the worm 26 in the second transverse transmission component 6-3, thereby driving the slide table 6-5 to make lifting and lowering movements. The movement of the slide table 6-5 synchronously drives the support plate 6-1 to move, realizing the corresponding channel diameter control adjustment process.

[0019] Specific Implementation Method Two: This implementation method is a further limitation of Specific Implementation Method One. In this implementation method, the vibrating crushing mechanism 2 includes a feeding hopper 2-1, a driving drive wheel 2-2, a driven drive wheel 2-3, a conveyor belt 2-4, and a second drive motor 2-5. The feeding hopper 2-1 is a strip-shaped box. The top side of the feeding hopper 2-1 is an open side, and a second feed inlet 21 is provided on the open side. The bottom side of the feeding hopper 2-1 is an inclined side, and a second discharge outlet 22 connected to the vibrating screening mechanism 3 is machined on the inclined side of the feeding hopper 2-1. The driving drive wheel 2-2 and the driven drive wheel 2-3 are arranged side by side at both ends inside the feeding hopper 2-1. A conveyor belt 2-4 is arranged between the driving drive wheel 2-2 and the driven drive wheel 2-3. The top side of the conveyor belt 2-4 is the conveying side for the fiber composite particles. The second drive motor 2-5 is connected to the driving drive wheel 2-2. The connecting frame 6-10 is fixedly connected to the top side of the feeding hopper 2-1.

[0020] In this embodiment, the conveyor belt 2-4 is an existing chain or other stainless steel belt. To improve the internal structural compactness of the vibratory crushing mechanism 2, the second drive motor 2-5 is arranged in the hopper 2-1. The small wheel belt assembly 25 enables power steering and speed adjustment. The small wheel belt assembly 25 is arranged on the outer wall of the hopper 2-1 and includes a first drive wheel, a second drive wheel, and a conveyor belt. A conveyor belt is provided between the first drive wheel and the second drive wheel. The first drive wheel is a large wheel, and the second drive wheel is a small wheel. When the second drive motor 2-5 is installed in the hopper 2-1, its power output shaft is connected to the second drive wheel, and the first drive wheel is coaxially connected to the drive wheel 2-2. This forms the process where the second drive motor 2-5 completes the steering drive through the small wheel belt assembly 25, which helps to improve the compactness of the structural layout.

The height of the material channel 7 is set in accordance with the particle size of the fiber composite material.

[0023] In this embodiment, the conveyor belt 2-4 is also equipped with a tension adjustment component 24. The tension adjustment component 24 is used as an emergency quick adjustment measure when the conveyor belt 2-4 is not taut enough or when the diameter control accuracy is unstable and loose when combined with the self-adjusting electromagnetic vibration component 6.

[0024] Specific Implementation Method Five: This implementation method is a further limitation of Specific Implementation Methods One, Two, Three, or Four. In this implementation method, when the slide table 6-5 drives the support plate 6-1 to reciprocate up and down along the length direction of the vertical worm gear 6-4, moving closer to or away from the vibrating plate 6-9, the material channel 7 formed between the bottom surface of the vibrating plate 6-9 and the top surface of the conveyor belt 2-4 is a lower fixed particle size channel, and an upper variable diameter channel is formed between the top surface of the vibrating plate 6-9 and the bottom surface of the support plate 6-1. This channel is a channel whose height can be temporarily adjusted for emergency situations or other non-stop operation.

[0025] Specific Implementation Method Six: This implementation method is a further limitation of Specific Implementation Methods One, Two, Three, Four, or Five. In this implementation method, another fixing form of the vertical worm gear 6-4 is that it is completely fixed to the inner wall of the connecting frame 6-10. That is, when both ends of each vertical worm gear 6-4 are respectively connected to the inner wall of the connecting frame 6-10, the slide table 6-5 is connected to the vibrating plate 6-9 and the support plate 6-1 respectively. The slide table 6-5 drives the support plate 6-1 and the vibrating plate 6-9 to make reciprocating up-and-down movements along the length direction of the vertical worm gear 6-4, moving closer to or away from the conveyor belt 2-4. The material channel 7 formed between the bottom surface of the vibrating plate 6-9 and the top surface of the conveyor belt 2-4 is a lower diameter changing channel, and an upper fixed channel is formed between the top surface of the vibrating plate 6-9 and the bottom surface of the support plate 6-1. This channel is a channel whose height can be temporarily adjusted for emergency situations or other non-stop operation.

[0026] Specific Implementation Method Seven: This implementation method is a further limitation of Specific Implementation Methods One, Two, Three, Four, Five, or Six. In this implementation method, a sliding guide assembly is provided on the connecting frame 6-10. The sliding guide assembly includes multiple slide rails 8-1 and multiple sliders 8-2.

[0028] Specific Implementation Method Nine: This implementation method is a further limitation of Specific Implementation Method One, Two, Three, Four, Five, Six or Seven. In this implementation method, when any three of the four vertical worm gears 6-4 are replaced with guide posts 6-7, the slide table 6-5 corresponding to each guide post 6-7 is replaced with a guide connecting sleeve.

[0029] The vertical drive mechanism of the vertical worm gear 6-4 and the slide table 6-5 can also be replaced by the existing linear slide table, which is the existing linear slide table, and its working process is the same as that of the existing linear slide table.

[0030] The structures and connections not mentioned in this embodiment are the same as those in specific embodiments one, two, three, four, five, six, seven, or eight.

[0031] When this utility model is used in existing crushing devices or integrated crushing and sorting devices for fiber composite materials, the connection relationship for connecting with other crushing and screening structures is as follows: The main support shell 5 is equipped with a vibrating crushing mechanism 2 and a vibrating screening mechanism 3 arranged sequentially from top to bottom inside. The primary crushing mechanism 1 is located on the top outer wall of the main support shell 5. The top and bottom of the primary crushing mechanism 1 are respectively provided with a first feed inlet 10 and a first discharge outlet. The top and bottom of the vibrating crushing mechanism 2 are respectively provided with a second feed inlet 21 and a second discharge outlet 22. The top and bottom of the vibrating screening mechanism 3 are respectively provided with a third feed inlet 31 and a third discharge outlet 32. The first discharge outlet of the primary crushing mechanism 1 is set towards the second feed inlet 21 of the vibrating crushing mechanism 2, and the second discharge outlet 22 of the vibrating crushing mechanism 2 is set towards the third feed inlet 31 of the vibrating screening mechanism 3. The negative pressure ventilation system 4 is connected to the vibrating screening mechanism 3. The self-adjusting electromagnetic vibrator 6 is set on the vibrating crushing mechanism 2. The primary crushing mechanism 1, the vibrating crushing mechanism 2, and the vibrating screening mechanism 3 perform a multi-stage crushing process without stopping the particle size conversion through the self-adjusting electromagnetic vibrator 6.

[0032] The integrated crushing and sorting device for fiber composite materials in this embodiment features a compact, integrated structure. It utilizes the coordinated operation of a primary crushing mechanism 1, a vibrating crushing mechanism 2, a vibrating screening mechanism 3, and a self-adjusting electromagnetic vibrator 6 to perform multi-stage sorting processes, including primary crushing followed by size control and secondary vibrating crushing followed by screening. This integrated crushing and sorting device ensures improved uniformity of particle size distribution in the crushed fiber-reinforced polymer products, clear grading, and minimal diffusion of fiber debris generated during crushing, resulting in a green, end-to-end crushing and grading process. Furthermore, the combination of the vibrating crushing mechanism 2 and the self-adjusting electromagnetic vibrator 6 allows for precise and detailed control of the fiber particle size after secondary vibrating crushing. The crushed material falls into the vibrating screening mechanism 3 under gravity, where different mesh sizes are used to grade and screen fiber materials with varying parameters to meet different subsequent utilization needs.

[0033] The primary crushing mechanism 1 includes a support box 1-1, a main cutter 1-2, a driving gear 1-3, a driven gear 1-4, a secondary cutter 1-5, and a first drive motor 1-6. The support box 1-1 and the first drive motor 1-6 are horizontally arranged side by side on the top of the main support shell 5. The top of the support box 1-1 is machined with the first feed inlet 10, and the bottom of the support box 1-1 is machined with the first discharge outlet. The main cutter 1-2 and the secondary cutter 1-5 are arranged inside the support box 1-1 along its length, and an interlaced cutting slit 1-7 is formed between the main cutter 1-2 and the secondary cutter 1-5. The power output end of motor 1-6 passes through the carrier box 1-1 and is connected to one end of the main cutter 1-2. The other end of the main cutter 1-2 passes through the carrier box 1-1 and is coaxially connected to the drive gear 1-3. The end of the auxiliary cutter 1-5 near the first drive motor 1-6 is hinged to the inner wall of the carrier box 1-1. The other end of the auxiliary cutter 1-5 passes through the carrier box 1-1 and is coaxially connected to the driven gear 1-4. The drive gear 1-3 and the driven gear 1-4 mesh with each other. The main cutter 1-2 and the auxiliary cutter 1-5 perform the primary crushing and cutting motion on the fiber composite material through the drive gear 1-3, the driven gear 1-4 and the first drive motor 1-6.

[0034] Working principle: After the primary crushed material particles enter the vibratory crushing mechanism 2, when it is necessary to select fiber composite particles with larger particle sizes, the electromagnetic vibrator 6-8 in the self-adjusting electromagnetic vibrator 6 and the third drive motor 6-6 are activated. The first transverse transmission component 6-2, two second transverse transmission components 6-3, four vertical worm gears 6-4 and four slides 6-5 cooperate to lift the vibratory plate 6-9, so that the height of the material channel 7 is adjusted to a height that matches the predetermined particle size. Then, it is conveyed by the conveyor belt 2-4, thereby completing the vibration crushing process of the primary crushed material particles according to the predetermined particle size.

[0035] Similarly, when it comes to selecting fiber composite particles with smaller particle sizes, the self-adjusting electromagnetic vibrator 6 is adjusted so that the height of the material channel 7 is adjusted to match the predetermined particle size, and then conveyed by the conveyor belt 2-4, thereby completing the vibration crushing process of the primary crushed material particles according to the predetermined particle size.
