For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0034] In one embodiment of this utility model, such as Figures 1-4 As shown, a rubber crusher is provided, including a frame 1, a drive mechanism 2, a rolling cutting mechanism 3 and a feeding mechanism 4. The drive mechanism 2 is connected to the frame 1, the rolling cutting mechanism 3 is connected to the drive mechanism 2, and the feeding mechanism 4 is connected to the frame 1 and is disposed below the rolling cutting mechanism 3.

[0035] The drive mechanism 2 includes a drive assembly 21 and a transmission assembly 22. The drive assembly 21 is located on one side of the frame 1 and is connected to the transmission assembly 22. The transmission assembly 22 is connected to the drive assembly 21 and the rolling assembly, respectively.

[0036] The rolling cutting mechanism 3 includes a rolling cutting shaft 31 and a rolling cutting head 32. The rolling cutting shaft 31 is fixedly connected to the transmission assembly 22 and the rolling cutting head 32 respectively. The rolling cutting head 32 is located above the feeding mechanism 4.

[0037] The feeding mechanism 4 includes a feeding screen cylinder 41 and a feeding box 42. The feeding screen cylinder 41 is located below the rolling cutting shaft 31 and is fixedly connected to the frame 1. The feeding box 42 is located below the feeding screen cylinder 41 and is fixedly connected to the frame 1.

[0038] The rubber crusher provided in this application, by setting three parallel, spaced-apart rolling cutter heads 32 in the rolling cutting mechanism 3, with each rolling cutter head 322 having its cutter head 322 evenly distributed in a ring shape, can crush rubber from multiple angles, resulting in more thorough crushing and more uniformly sized rubber blocks, thus improving the quality of subsequent processing. The arc-shaped transition design at the connection between the cutter head 322 and the cutter body 321 reduces the frictional resistance between the rubber and the cutter head 322 during the crushing process, further improving crushing efficiency.

[0039] In another embodiment of this utility model, the drive assembly 21 includes a motor base 211, a drive motor 212, a drive shaft, and a drive pulley 214. The motor base 211 is disposed on one side of the frame 1, the drive motor 212 is fixedly connected to the motor base 211, one end of the drive shaft is fixedly connected to the drive motor 212, and the other end is fixedly connected to the drive pulley 214. Further, the transmission assembly 22 includes a transmission belt 221, a driven pulley 222, a counterweight wheel 223, and a transmission bearing 224. The transmission belt 221 is fixedly wound around the drive pulley 214 and the driven pulley 222, respectively. The driven pulley 222 and the counterweight wheel 223 are both fixedly connected to the outside of the cutting shaft 31. The driven pulley 222 is disposed at one end of the cutting shaft 31, and the counterweight wheel 223 is disposed at the other end of the cutting shaft 31. Two transmission bearings 224 are provided, both of which are fixedly connected to the frame 1, and the cutting shaft 31 is fixedly mounted on the transmission bearings 224.

[0040] When the drive motor 212 is started, the electrical energy inside the motor is converted into mechanical energy, driving the drive shaft to rotate. Since one end of the drive shaft is fixedly connected to the drive motor 212 and the other end is fixedly connected to the drive pulley 214, the drive shaft will drive the drive pulley 214 to rotate synchronously. The transmission belt 221 is wound around the drive pulley 214 and the driven pulley 222 respectively. When the drive pulley 214 rotates, the friction between the belt and the pulley drives the transmission belt 221 to move, and the transmission belt 221 then drives the driven pulley 222 to rotate. The driven pulley 222 is fixed to one end of the rolling cutting shaft 31. As the driven pulley 222 rotates, the rolling cutting shaft 31 also begins to rotate. The other end of the rolling cutting shaft 31 is fixed with a counterweight wheel 223, which makes the rolling cutting shaft 31 more stable during rotation. Two transmission bearings 224 are fixed on the frame 1, and the rolling cutting shaft 31 is installed inside the transmission bearings 224. The transmission bearings 224 provide support and reduce friction, ensuring that the rolling cutting shaft 31 can rotate smoothly. The drive motor 212 serves as the power source, transmitting power to the transmission belt 221 through the drive shaft and the drive pulley 214. The transmission belt 221 then transmits power to the driven pulley 222, thereby driving the rolling cutting shaft 31 and the rolling cutting head 32 to rotate, ultimately realizing the rubber crushing work of the rolling cutting mechanism 3.

[0041] In another embodiment of this utility model, there are three rolling cutter heads 32, all of which are fixedly connected to the rolling cutter shaft 31, and adjacent rolling cutter heads 32 are arranged in parallel and at intervals.

[0042] Three cutter heads 322 can simultaneously crush rubber, covering a larger area compared to a single or two cutter heads 322. As the rolling shaft 31 rotates, the rubber is processed within the action area of ​​multiple cutter heads 322, increasing the crushing volume per unit time and significantly improving crushing efficiency. The parallel and spaced cutter heads 322 apply force to the rubber from different positions and angles during the crushing process. As the rubber passes through the area of ​​the cutter heads 322, it is repeatedly cut and compressed by multiple cutter heads 322, resulting in more thorough crushing and avoiding incomplete crushing in certain areas. This leads to more uniform rubber block size, which is beneficial for subsequent processing. The coordinated work of multiple cutter heads 322 generates greater crushing force on the rubber. For rubber raw materials with high hardness or large blocks, multiple cutter heads 322 can gradually crush them into smaller particles, ensuring crushing quality and adapting to the crushing needs of different types of rubber raw materials.

[0043] In another embodiment of the present invention, the rolling cutter head 32 includes a cutter body 321 and a cutter head 322. There are three cutter heads 322, which are uniformly and fixedly connected to the cutter body 321 in a ring shape. An arc-shaped transition part is provided at the connection between the cutter head 322 and the cutter body 321.

[0044] Three uniformly distributed ring-shaped cutter heads 322, driven by the rolling cutting shaft 31, can simultaneously cut and compress the rubber raw material from different directions, causing the rubber to be subjected to force in multiple directions and resulting in more thorough crushing. The arc-shaped transition section at the connection between the cutter head 322 and the cutter body 321 avoids sharp edges at the connection point, allowing the rubber to pass through the transition area more smoothly during contact and crushing with the cutter head 322, reducing friction and resistance between the rubber and the cutter head 322. This not only reduces energy consumption during equipment operation but also reduces wear on the cutter head 322, extending its service life.

[0045] In another embodiment of this utility model, a fixing plate 43 is provided between the feeding screen cylinder 41 and the frame 1, and a fixing bolt 44 is provided between the feeding screen cylinder and the fixing plate 43. The fixing bolt 44 is sequentially fixed through the feeding screen cylinder and the fixing plate 43, and a fixing nut is threaded onto the fixing bolt 44.

[0046] Using a fixing plate 43 as an intermediate connecting component, along with fixing bolts 44 and fixing nuts, the feeding screen cylinder 41 is tightly connected to the frame 1. The fixing bolts 44 pass through the screen cylinder and fixing plate 43 in sequence, and are then tightened with fixing nuts, generating a strong clamping force to firmly fix the feeding screen cylinder 41 to the frame 1. During long-term operation of the rubber crusher, even under external forces such as vibration and the impact of falling rubber, the feeding screen cylinder 41 can be effectively prevented from loosening or shifting, ensuring the stable operation of the feeding mechanism 4. The bolt-nut connection allows for easy installation of the feeding screen cylinder 41; simply align the screen cylinder with the fixing plate 43, insert the fixing bolts 44, and tighten the nuts. When cleaning, repairing, or replacing the feeding screen cylinder 41, simply unscrew the fixing nuts and remove the fixing bolts 44 to easily disassemble the feeding screen cylinder 41.

[0047] In another embodiment of the present invention, the feeding screen cylinder 41 is arranged in an arc shape and is provided with a plurality of feeding holes 411. The feeding holes 411 are provided in a plurality of manner and are evenly arranged in the feeding screen cylinder 41, with adjacent feeding holes 411 spaced apart.

[0048] The arc-shaped feeding screen cylinder 41 design, compared to a planar structure, increases the capacity of the screen cylinder and the material flow space, making the flow of crushed rubber within the screen cylinder smoother. Rubber particles can move downwards from the screen cylinder more quickly, shortening the material's residence time within the screen cylinder, thereby improving overall feeding efficiency.

[0049] Multiple evenly spaced discharge holes 411 ensure that the rubber granules have sufficient channels to fall. This avoids localized blockages caused by the concentration or uneven distribution of the discharge holes 411. When the rubber granules reach the discharge holes 411, they can fall evenly, reducing the possibility of granule accumulation and blockage of the discharge holes 411, and ensuring a continuous and stable discharge process.

[0050] The evenly distributed feeding holes 411 allow rubber granules to pass through the screen cylinder and enter the feeding box 42 uniformly. This helps ensure a consistent distribution of rubber granules during subsequent processing, avoiding situations where there is too much or too little material in some areas, thereby improving the stability and consistency of processing quality.

[0051] The rubber crusher provided in this application, by setting three parallel, spaced-apart rolling cutter heads 32 in the rolling cutting mechanism 3, with each rolling cutter head 322 having its cutter head 322 evenly distributed in a ring shape, can crush rubber from multiple angles, resulting in more thorough crushing and more uniformly sized rubber blocks, thus improving the quality of subsequent processing. The arc-shaped transition design at the connection between the cutter head 322 and the cutter body 321 reduces the frictional resistance between the rubber and the cutter head 322 during the crushing process, further improving crushing efficiency.

[0052] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
