Description

Technical Field

[0001] The utility model relates to the technical field of rubber grinding, in particular to a rubber grinding particle device. Background Art

[0002] Rubber cutting and grinding machine is a kind of equipment specially used for processing rubber block materials. It cuts and grinds rubber blocks into required particles or powder through a specific grinding mechanism. This equipment plays an important role in the production and recycling of rubber products.

[0003] For example, the Chinese patent "CN110640943A" discloses a rubber grinding particle equipment, which proposes: a first driving mechanism is provided on the top of the body and a second driving mechanism is provided on the bottom, a block grinding mechanism is provided in the inner cavity of the body, a feed port is provided on the outer wall of the body, a heating layer is embedded in the inner wall of the body, and a sound-absorbing layer is fixedly provided on the inner side of the heating layer. The utility model utilizes a plurality of gears and crown teeth to mesh, and drives the third rotating shaft to rotate through a second driving motor, so that the transmission is completed between the plurality of gears and the crown teeth, and drives the two grinding rollers located at the bottom of the inner cavity of the body to work, and at the same time, an asymmetric gear arrangement is provided, so that the two grinding rollers turn in opposite directions and move relative to each other, and the waste rubber material is ground into particles of uniform size, and the grinding of the waste rubber can be completed in the shortest time, and the grinding efficiency of the rubber can be improved at the same time, and no pollutants are generated in the whole process, which is environmentally friendly and efficient.

[0004] It can be seen from the above-mentioned device that although a device that can efficiently grind waste rubber is proposed, the current technical solution still has the following shortcomings:

[0005] At present, when rubber products are recycled in an environmentally friendly manner, pretreatment is required. By cutting, waste rubber can be broken down into smaller units for subsequent treatment and processing. This pretreatment can improve treatment efficiency and reduce the difficulty of subsequent processes. Secondly, grinding can make waste rubber reach a smaller particle size, which is crucial for the reuse of rubber. The ground rubber particles can be more easily mixed with other materials for the manufacture of new rubber products. In addition, grinding also helps to increase the surface area of ​​the rubber, thereby improving its bonding performance with other materials. However, existing machines cannot cut and grind rubber at the same time. The integrated machines currently manufactured need to install multiple motors to drive them, which wastes costs and increases the equipment usage area. In addition, when the integrated machine grinds the rubber, there is only one grinding process, and it is impossible to grind coarsely first and then finely. While the efficiency is reduced, the grinding head is also easily damaged. The particle size cannot be kept consistent after grinding, and secondary processing may be required later, which seriously affects work efficiency. Utility Model Content

During grinding, the rubber product after internal cutting can also be stirred, so that it can be ground in all directions, thereby improving the grinding efficiency and preventing the internal blockage of the machine during the grinding process. The utility model solves the problem that the existing machines cannot cut and grind rubber at the same time. The currently manufactured integrated machines need to install multiple motors to drive them, which wastes costs and increases the equipment usage area. In addition, when the integrated machine grinds rubber, there is only one grinding process, and it is impossible to grind coarsely first and then finely. The efficiency is reduced and the grinding head is also easily damaged.

[0018] 3. The environmentally friendly rubber cutting and grinding machine, through the cooperation between the large screen plate and the scraper, achieves that when the recycled rubber is put into the grinder for cutting, the large screen plate supports the rubber block and provides cutting support for the rubber block before grinding.

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Embodiment 1 of the present invention: Please refer to Figure 1-4 A rubber grinding particle equipment comprises a grinder 1, an inner wall of the grinder 1 is provided with an annular tooth plate 16, an inner wall of the grinder 1 is provided with a coarse grinding plate 17 in an annular manner, an upper outer wall of the grinder 1 is provided with a feed port 11, a lower outer wall of the grinder 1 is provided with a discharge port 12, an outer wall of the grinder 1 is provided with a bracket 13, an inner wall of the grinder 1 is provided with an annular chute 14, a large screen plate 15 is provided below the chute 14, a surface of the large screen plate 15 is provided with a plurality of large holes for dropping materials, the large screen plate 15 is movably mounted on the outer wall of a rotating shaft 21, a fine screen plate 18 is provided at the bottom of the inner wall of the grinder 1, a surface of the fine screen plate 18 is provided with a plurality of small holes for dropping materials, and the fine screen plate 18 is movably mounted on the outer wall of the rotating shaft 21.

[0029] First, the grinder 1, as the main body of the entire equipment, provides space for grinding the rubber blocks. The annular tooth plate 16 and the coarse grinding plate 17 arranged on its inner wall together constitute a preliminary grinding mechanism, which can coarsely grind the incoming rubber blocks to make them smaller, which is convenient for subsequent fine grinding. The feed port 11 arranged on the upper outer wall of the grinder 1 allows the rubber blocks to easily enter the grinder for grinding. The discharge port 12 below allows the ground rubber particles to be discharged smoothly, completing the entire grinding process. The large holes on the surface of the large screen plate 15 allow the rubber particles cut to a certain extent to fall smoothly and enter the next stage of grinding. The fine screen plate 18 is set to finely screen the ground rubber particles. The small holes on its surface only allow particles that meet the requirements to pass through, thereby ensuring the uniformity of the particles after grinding.

[0030] See also Figure 3-5 A grinding motor 2 is arranged above the grinder 1. The grinding motor 2 is fixedly connected to a rotating shaft 21 through an output shaft. The rotating shaft 21 is movably installed inside the grinder 1. Two sets of blades 22 are arranged above the outer wall of the rotating shaft 21. A scraper 23 is fixedly installed on the outer wall of the rotating shaft 21. The scraper 23 is fitted above the large screen plate 15. An arc-shaped slider arranged at the outer end of the scraper 23 is movably installed inside the slide groove 14.

[0031] The two sets of blades 22 arranged above the outer wall of the rotating shaft 21 are key components in the grinder. They rotate at high speed with the rotation of the rotating shaft 21 to cut and crush the rubber blocks entering the grinder. This design can greatly improve the grinding efficiency, so that the rubber blocks can be effectively crushed into smaller particles in a short time. The setting of the scraper 23 further enhances the function of the grinder. It is fixedly installed on the outer wall of the rotating shaft 21 and is fitted above the large screen plate 15. When the rotating shaft 21 rotates, the scraper 23 also rotates, and its edge will continuously scrape the surface of the large screen plate 15. This action has two main functions: one is to help scrape off the rubber particles attached to the large screen plate 15 to prevent clogging; the other is to further crush the rubber blocks that have not been completely crushed, so that they can pass through the holes of the large screen plate 15 faster and enter the next stage of grinding. The arc-shaped slider arranged at the outer end of the scraper 23 is movably installed inside the slide 14. This design allows the scraper 23 to move along the slide 14 while rotating. This movement not only increases the flexibility of the scraper 23, so that it can better adapt to the curved surface of the large screen plate 15, but also helps to adjust the distance between the scraper 23 and the large screen plate 15, thereby optimizing the scraping effect. The two sets of blades 22 and the scraper 23 arranged above the outer wall of the rotating shaft 21, as well as the arc-shaped slider and the slide 14 arranged at the outer end of the scraper 23, together constitute the efficient grinding and cleaning system of this environmentally friendly rubber block grinder. This system not only improves the grinding efficiency, but also ensures the continuous and stable operation of the grinder, reducing failures and downtime caused by blockage or residue.

[0032] Embodiment 2 of the present invention: Please refer to Figure 3-6 A rubber grinding particle equipment comprises a grinder 1, a grinding motor 2 is arranged above the grinder 1, the grinding motor 2 is fixedly connected to a rotating shaft 21 through an output shaft, the rotating shaft 21 is movably installed inside the grinder 1, a limiting ring 24 is movably installed in the middle of the outer wall of the rotating shaft 21, a plurality of connecting plates 241 are arranged in an annular matrix on the outer wall of the limiting ring 24, a limiting rod 242 is fixedly installed inside the connecting plate 241, a passive gear 243 is movably installed on the outer wall of the limiting rod 242, and the passive gear 243 is installed on the annular gear plate 1 through surface engagement with the teeth 6. A plurality of passive gears 243 are meshed with active gears 244 through surface teeth. The active gears 244 are fixedly mounted on the outer wall of the rotating shaft 21. A coarse grinding roller 245 is arranged below the passive gear 243. The coarse grinding roller 245 and the coarse grinding plate 17 are arranged to cooperate with each other for grinding. A mounting ring 25 is fixedly mounted on the bottom of the outer wall of the rotating shaft 21. Four connecting rods 251 are arranged in a circular matrix on the outer wall of the mounting ring 25. A fine grinding roller 252 is movably mounted on the outer wall of the connecting rod 251. The fine grinding roller 252 is fitted above the fine sieve plate 18.

[0033] The design of the limit ring 24 is not only to limit the moving range of the rotating shaft 21, it also carries more functions. Through the plurality of connecting plates 241 arranged in the outer wall annular matrix, the limit ring 24 forms a close connection with other parts of the grinder. The limit rods 242 fixedly installed inside these connecting plates 241 not only enhance the stability of the structure, but also provide support for the installation of the passive gear 243. The passive gear 243 is meshed with the annular gear plate 16 through the surface teeth. This design makes it possible for the passive gear 243 to rotate with the rotating shaft 21 through the drive of the active gear 244, and the passive gear 243 will rotate and move along the annular gear plate 16 while rotating. This gear transmission method ensures the effective transmission of power and makes the rotational motion more stable and reliable. The setting of the coarse grinding roller 245 corresponds to the coarse grinding plate 17 to form a preliminary grinding mechanism for the rubber block. When the coarse grinding roller 245 rotates with the rotation of the passive gear 243, it will crush and break the rubber blocks, making them gradually smaller. This grinding method is both efficient and uniform, and can ensure that the rubber blocks are fully ground. In the later stage of grinding, the fine grinding roller 252 plays a key role. It is fitted above the fine screen plate 18 and rotates with the rotation of the rotating shaft 21. The rotation of the fine grinding roller 252 will further grind and refine the rubber particles after coarse grinding to achieve a smaller particle size. At the same time, the small holes on the fine screen plate 18 only allow particles that meet the requirements to pass through, thereby ensuring the uniformity and quality of the final product. The design of the limit ring 24 and its related components enables this environmentally friendly rubber block grinder to achieve efficient, uniform and continuous grinding during the grinding process, thereby improving production efficiency and ensuring product quality.

[0034] The complete use steps and working principles of the above-mentioned embodiments 1 to 2 are as follows:

[0035] First, the environmentally friendly recycled rubber is put into the grinder 1 from the feed port 11. When the rubber enters the grinder 1, the two layers of blades 22 are driven by the rotating shaft 21 to cut it. During the cutting process, the cut pieces will fall on the large screen plate 15. The rotating shaft 21 drives the scraper 23 above the large screen plate 15 to slide along the inner wall of the grinder 1 in the chute 14, so that the scraper 23 drives the cut pieces to move above the large screen plate 15. After cutting, the pieces that are smaller than the holes on the surface of the large screen plate 15 fall from the holes below, and those that do not meet the size are further cut by the blades 22. After meeting the size, they are driven by the scraper 23 to fall from the holes of the large screen plate 15.

[0036] Secondly, after falling, the larger cut pieces first fall into the gap between the coarse grinding roller 245 and the coarse grinding plate 17 arranged on the inner wall of the grinder, and then drive the active gear 244 to rotate through the rotating shaft 21, and the active gear 244 drives the several passive gears 243 installed by the engagement of the latch teeth to rotate, and when the passive gear 243 rotates, it drives the coarse grinding roller 245 below it to cooperate with the coarse grinding plate 17 to synchronously coarsely grind the cut rubber block, and in the process of the coarse grinding roller 245 rotating and grinding, the upper passive gear 243 engages with the annular tooth plate 16, so that the coarse grinding roller 245 moves along the annular tooth plate 16 while rotating and grinding, and when the coarse grinding roller 245 rotates and moves, it plays a role of stirring the internal rubber block, so that the grinding efficiency of the rubber block becomes higher, and the rubber block is driven to turn over during stirring and prevents the large rubber block from being blocked and stuck.

[0037] Secondly, after the rubber block is roughly ground, its volume becomes smaller and falls onto the fine screen plate 18 below. The rotating shaft 21 drives the mounting ring 25 to rotate, and the mounting ring drives the four connecting rods 251 on its outer wall to rotate. When the connecting rod 251 rotates around the rotating shaft 21, the fine grinding roller 252 on its outer wall rotates above the fine screen plate 18 through friction. The rubber block above the fine screen plate 18 is ground by the high-speed rotation of the fine grinding roller 25, and the downward force of the fine grinding roller 25 on the rubber squeezes the rubber into the holes opened in the fine screen plate 18, so that the rubber blocks are all turned into particles of uniform size and fall from the holes of the fine screen plate 18. The ground rubber particles fall into the cavity below and are discharged from the discharge port 12.

[0038] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
