[0018] Next, the technical solutions in the embodiments of the present invention will be described clearly and completely. For the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] Embodiment 1: Please refer to Figures 1-9 , a graphite crushing and mixing device, including a main body 1 of the crushing device, a feed inlet part 2 is arranged at the top of the main body 1 of the crushing device, a discharge port connection part 3 is arranged at the bottom, and crushing rollers 4 are symmetrically arranged in the inner cavity of the main body 1 of the crushing device. Crushing teeth 41 are arranged on the outer side wall of the crushing roller 4; wherein an installation window 5 is arranged on the side wall of the main body 1 of the crushing device, the installation window 5 is connected to the inner cavity of the main body 1 of the crushing device, and first installation clamping plates 501 are symmetrically and fixedly arranged on the inner side of the installation window 5, and a crushing and cleaning mechanism is arranged in the installation window 5.

[0020] Among them, for the crushing teeth 41 arranged on the crushing roller 4, they are equidistantly arranged on the circumferential side wall of the crushing roller 4, and a gap groove is formed between adjacent crushing teeth 41 along the axial direction of the crushing roller 4, and the scraping hook 605 in the crushing and cleaning mechanism corresponds to the position of the gap groove, that is, after the bearing sealing plate 601 is clamped in the installation window 5 and then fixed by screws, the arranged support rod member 604 is installed on the inner side of the bearing sealing plate 601. That is, after the bearing sealing plate 601 is installed and fixed, the scraping hook 605 at the end of the arranged support rod member 604 is in the gap groove between adjacent crushing teeth 41, and the hook head of the scraping hook 605 contacts the outer side wall of the crushing roller 4. Among them, the connecting plate member 602 is fixedly arranged on the inner side wall of the bearing sealing plate 601 by screws, which enables the support rod member 604 to have a detachable operation, facilitating later maintenance or replacement work.

[0021] For the crushing of graphite materials, the graphite materials enter from the feed port 2 at the top of the main body 1 of the crushing device, and then are crushed by the symmetrically arranged crushing rollers 4. The crushing rollers 4 are driven by a set driving motor, and the driving motor is arranged outside the main body 1 of the crushing device. The crushed materials are discharged from the discharge port connecting part 3. During the crushing process, some materials may be stuck in the gap grooves between adjacent crushing teeth 41, that is, the space between adjacent crushing teeth 41 along the axis direction of the crushing roller 4.

[0022] In order to prevent the materials stuck in the gap grooves from not being crushed, in this solution, a crushing and cleaning mechanism is set up to clean the materials stuck in the gap grooves. There are two groups of the crushing and cleaning mechanisms symmetrically arranged on both sides of the main body 1 of the crushing device. The bearing sealing plate 601 in the crushing and cleaning mechanism is adaptively stuck in the installation window 5 and fixed by screws. One side of the connecting plate 602 is fixedly provided with a bearing strip 603, and the connecting plate 602 is fixedly arranged on the inner side of the bearing sealing plate 601 by screws. The supporting rods 604 are welded equidistantly on the bearing strip 603 and are arranged equidistantly and linearly; one end of the supporting rod 604 is fixedly provided with a scraping hook 605. The number of the scraping hooks 605 is the same as that of the supporting rods 604. One scraping hook 605 is fixedly arranged at one end of one supporting rod 604, and the direction of the scraping hook 605 is downward. When the crushing roller 4 rotates to crush the graphite materials by extrusion, the hook head of the scraping hook 605 arranged at one end of the supporting rod 604 contacts the crushing roller 4 and scrapes the materials in the gap grooves formed by adjacent crushing teeth 41 to scrape off the materials stuck in the gap grooves. The crushing teeth 41 arranged on the crushing roller 4 are arranged equidistantly in a ring shape, and the equidistantly arranged crushing teeth 41 in a ring shape are also arranged equidistantly along the axis direction of the crushing roller 4. That is, the gap grooves formed between adjacent crushing teeth 41 along the axis direction of the crushing roller 4 are also equivalent to a ring groove. When the crushing roller 4 rotates, the scraping hook 605 is located in the ring groove, and the number of the scraping hooks 605 is the same as that of the ring grooves.

[0023] When scraping the materials stuck in the gap grooves by the scraping hook 605, if the materials are stuck very tightly, in order to improve the cleaning effect, in this solution, scraping cutting edges 606 are arranged at the inner side position of the scraping hook 605. The scraping cutting edges 606 at the inner side of the scraping hook 605 are symmetrically arranged. At this time, the arranged scraping cutting edges 606 form a cutting knife, that is, it has a cutting effect on the materials stuck relatively tightly and can further improve the material cleaning effect.

[0024] In order to further improve the cleaning effect of the materials. For example, when scraping the materials stuck in the gap groove by the scraping hook 605, if there are small materials adhering to the gap groove, the present solution uses the provided auxiliary component to clean them. An auxiliary component is provided on the support rod 604. One end of the support bar 701 in the auxiliary component is fixedly arranged at the top of the support rod 604, and the support bar 701 is inclined. The number of sets of the support bar 701 and the support rod 604 is the same. The other end of the support bar 701 is fixedly provided with a fixing plate 702; One end of the extension bar 704 is fixedly provided with a fixing disk 703, and the fixing disk 703 is fixedly connected to the fixing plate 702 by screws. The other end of the extension bar 704 is fixedly provided with a bearing disk 705; A cleaning brush 706 is arranged on the end face of the bearing disk 705. When scraping the materials by the scraping hook 605, if there are still small residues in the gap groove, the provided cleaning brush 706 is used to make up for the cleaning, ensuring the cleaning work efficiency and avoiding affecting the crushing work of the crushing roller 4.

[0025] Regarding the use of the cleaning brush 706, it is arranged on the bearing disk 705, and the bearing disk 705 is fixedly arranged at one end of the extension bar 704. The other end of the extension bar 704 is provided with a fixing disk 703, and the fixing disk 703 and the fixing plate 702 are fixedly connected by screws. It is detachably arranged. On the one hand, it is convenient for later maintenance and repair work. On the other hand, when it is not necessary to use the cleaning brush 706 for auxiliary cleaning, it can also be disassembled, and only the scraping hook 605 is used for scraping and cleaning work. When the cleaning brush 706 needs to be used, it can be installed according to the actual work requirements again, with excellent work flexibility.

[0026] For the overall installation work of the crushing and cleaning mechanism, first install the cleaning brush 706, that is, stick the fixed disk 703 on one side of the fixed plate 702 at the end of the support bar 701, and then fix the fixed disk 703 with screws. The installation of the cleaning brush 706 on one support bar 701 can be completed. Then, install the cleaning brush 706 on other support bars 701 according to the same operation method. Then, install the connecting plate 602 on the side wall of the bearing sealing plate 601 with screws. Finally, insert the bearing sealing plate 601 into the installation window 5 on the side wall of the crushing device main body 1, and the bearing sealing plate 601 is limited and blocked by the first installation clamping plate 501 inside the installation window 5. Then, fix the bearing sealing plate 601 with screws. Then, install the collection component, that is, install the scraping collection box 803. Directly insert the scraping collection box 803 into the installation socket 801 in the bearing sealing plate 601 until the second installation clamping plate 804 at one end of the scraping collection box 803 is in close contact with the bearing sealing plate 601. The installation work of the scraping collection box 803 can be completed.

[0027] When the crushing and cleaning mechanism scrapes the graphite material stuck in the gap groove on the crushing roller 4, the material will be collected by the collection component. The purpose of collection is to temporarily store the material scraped from the gap groove, and then pour it into the feeding port 2 at the top of the crushing device main body 1 uniformly for re-crushing work, improving the quality of the crushing work and avoiding waste of materials, which has a positive effect on improving the efficiency of the graphite crushing work. The bearing sealing plate 601 is provided with a collection component, and the collection component includes an installation socket 801, a support auxiliary bar 802, a scraping collection box 803, a second installation clamping plate 804 and an auxiliary handle 805. The installation socket 801 is arranged in the bearing sealing plate 601, and the scraping collection box 803 is adaptively inserted into the installation socket 801, and the scraping collection box 803 is arranged below the scraping hook 605. The front end of the scraping collection box 803 is fixedly provided with a second installation clamping plate 804, and the center position of the side wall of the second installation clamping plate 804 is provided with an auxiliary handle 805.

[0028] The scraped graphite material will fall into the scraping material collection box 803 for temporary storage. On the one hand, it can prevent the scraped material from scattering elsewhere and causing waste of resources. On the other hand, it can collect the scraped graphite material in a timely manner for subsequent unified processing. When it is necessary to disassemble the scraping material collection box 803 to process the collected graphite material, the scraping material collection box 803 can be directly pulled out by pulling the auxiliary handle 805 on the second installation clamping plate 804. Then, the collected material is poured at the position of the feeding port 2. After that, the crushing work is carried out again by the crushing roller 4 in the crushing device main body 1. For the installation of the scraping material collection box 803, the scraping material collection box 803 is directly inserted into the installation socket 801 in the bearing sealing plate 601 until the second installation clamping plate 804 provided at one end of the scraping material collection box 803 contacts the bearing sealing plate 601, that is, the second installation clamping plate 804 is clamped and limited with the bearing sealing plate 601, providing a limiting effect on the position of the scraping material collection box 803. And a supporting auxiliary strip 802 is fixedly arranged on the bottom side of the installation socket 801, and its function is to provide a supporting effect on the scraping material collection box 803 and improve the installation stability of the scraping material collection box 803.

[0029] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
