Description

Technical Field

[0001] This utility model relates to the field of crushing device technology, specifically a crushing device for pulverizing waste rubber tires. Background Technology

[0002] As is well known, waste tires can be efficiently converted into high-quality rubber powder through innovative processing. This process first involves finely crushing the tires using specialized crushing equipment, effectively solving the problem of the internal steel wire structure of the tires and ensuring thorough crushing. Subsequently, advanced separation technology is used to remove impurities, such as steel wires and fibers, to obtain pure rubber particles. These rubber powders are not only widely used in the construction of running tracks, flooring, and other fields, but can also be used in the production of modified plastics and rubber products, realizing the recycling of resources.

[0003] Existing tire shredding equipment generally uses shredders with cutter rollers to shred tires. However, for some large or complex waste tires, the cutter rollers may not be able to apply shredding force evenly, resulting in insufficient shredding of certain parts of the tire and the formation of large rubber blocks, which require secondary shredding and reduce overall production efficiency. Summary of the Invention

[0004] Technical problems to be solved

[0005] In order to overcome the problem of uneven crushing in existing waste rubber tire crushing devices, this utility model provides a crushing device for waste rubber tire crushing that can uniformly disperse waste rubber tires.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a crushing device for shredding and processing waste rubber tires, comprising:

[0008] support;

[0009] A shredder, which is fixedly mounted on the bracket;

[0010] The first motor is fixedly mounted on the side of the bracket, and the output shaft of the first motor is fixedly mounted to the crushing blade.

[0011] A screening assembly, which is mounted on the support;

[0012] A repeating assembly, mounted on the support, includes a receiving frame fixedly disposed on the side of the support, a conveying pipe fixedly disposed on the receiving frame, an auger installed inside the conveying pipe, and a conveying frame fixedly disposed on the top of the conveying pipe, one end of the conveying frame aligned with the crushing blade; and

[0014] Preferably, the screening component includes at least four slids, which are formed around the support frame. A screen is slidably disposed between the slids, and a slider is fixedly disposed around the screen. The slider is slidably disposed with respect to the slids, and a drive component is mounted on the support frame.

[0015] Furthermore, the drive assembly includes a second motor, which is mounted on the bracket, and a reciprocating crankshaft is fixedly disposed on the output shaft of the second motor, the reciprocating crankshaft being in contact with the bottom of the screen.

[0020] Beneficial effects

[0021] This waste rubber tire crushing device features a crushing blade fixedly mounted on a support. A primary motor drives the blade to rotate. The blade's structure and arrangement allow it to crush tires from different angles and positions, providing more flexible contact with various parts of the tire compared to a roller crusher. This results in a more even application of crushing force, reducing incomplete crushing in certain areas and improving the uniformity of the crushing process. A receiving frame collects the initially crushed material. An auger rotates within a conveying pipe, transporting the material to a conveying frame with one end aligned with the crushing blade. This allows materials that may not have been fully crushed to be further crushed by the blade. This design ensures thorough crushing while avoiding the waste of resources from secondary crushing of all materials. It improves crushing quality while maintaining a certain level of production efficiency. Targeted processing is provided for materials with different degrees of crushing. A screening component mounted on the support screens the crushed material, sending qualified materials to the collection component and reprocessing unqualified materials through a repeating component. The entire material handling process is more rational and orderly. Attached Figure Description

[0030] 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.

[0031] See Figures 1-7 A crushing device for shredding and processing waste rubber tires includes a support 1, a crushing blade 2, a first motor 3, a screening component 4, a repeating component 5, and a collection component 24.

[0032] The support frame 1 serves as the basic support structure for the entire device, providing a platform for the installation and fixing of other components. Made of robust metal, the support frame 1 possesses sufficient strength and stability to withstand various forces and vibrations generated during device operation. The crushing blade 2, fixed to the support frame 1, cuts and crushes waste rubber tires into smaller particles. The first motor 3, fixed to the side of the support frame 1, has its output shaft connected to the crushing blade 2. The first motor 3 powers the crushing blade 2, driving it to crush the waste rubber tires through high-speed rotation, ensuring efficient crushing. The screening component 4, mounted on the support frame 1, screens the crushed rubber particles, separating them into different grades based on particle size for subsequent processing. The receiving frame 6 of the repeating component 5, fixed to the side of the support frame 1, receives larger rubber fragments selected by the screening component 4. A conveying pipe 7 is fixed to the receiving frame 6, containing an auger 8. Driven by a motor, the auger 8 rotates, conveying the rubber fragments from the receiving frame 6 to the top of the conveying pipe 7. The auger 8 is designed to effectively prevent rubber fragments from being transported... To prevent blockages during delivery and ensure smooth conveying, a conveying frame 9 is fixed to the top of the conveying pipe 7. One end of the conveying frame 9 is aligned with the crushing blade 2. After the auger 8 conveys the rubber fragments to the conveying frame 9, the rubber fragments fall from the opening of the conveying frame 9 and re-enter the crushing area of ​​the crushing blade 2 for secondary crushing. The collecting component 24 is installed at the bottom of the support 1 to collect rubber particles that meet the requirements after screening. The collecting component 24 includes a chassis 16, which is fixedly installed at the bottom of the support 1 to provide a stable foundation for the entire collecting component 24. A sliding component 17 is installed on the top of the chassis 16, and a bearing frame 18 is slidably installed at the bottom of the sliding component 17. A handle 19 is fixedly installed on the side of the bearing frame 18 to facilitate the operator to move and transport the bearing frame 18. The crushing blade 2 includes at least two sets of staggered blade groups. Each set of blades contains at least three blades distributed at different angles, and the distribution angles of the blades in adjacent blade groups complement each other to ensure that more parts of the tire can be covered during the crushing process, further improving the uniformity of crushing.

[0033] First, refer to Figure 2 In this embodiment, the screening component 4 on the support 1 plays the role of screening the crushed rubber particles. It includes at least four sliding grooves 10, which are opened around the support 1 to provide a track for the sliding of the screen 11. Sliding blocks 12 are fixedly arranged around the screen 11. The sliding blocks 12 slide with the sliding grooves 10, so that the screen 11 can move within the range defined by the sliding grooves 10. This design allows the screen 11 to flexibly adjust its position in order to screen rubber particles at different positions. The presence of the screen 11 can divide the rubber particles into different grades according to the particle size, thereby providing convenience for subsequent processing.

[0034] Then, refer to Figure 4 In this embodiment, the driving component 13 provides power for the movement of the screen 11. In this embodiment, the driving component 13 includes a second motor 14 mounted on the bracket 1. A reciprocating crankshaft 15 is fixedly mounted on the output shaft of the second motor 14. The reciprocating crankshaft 15 is in contact with the bottom of the screen 11. When the second motor 14 starts, the output shaft drives the reciprocating crankshaft 15 to rotate. Since the reciprocating crankshaft 15 is in contact with the bottom of the screen 11, it will push the screen 11 to reciprocate in the chute 10. This reciprocating motion allows the rubber particles on the screen 11 to be continuously screened, improving the efficiency and effect of screening.

[0035] Secondly, see Figure 6 In this embodiment, the collection component 24 is used to collect rubber granules that meet the requirements after screening. It includes a chassis 16 fixedly installed at the bottom of the support 1, which provides a stable foundation for the entire collection component 24. A sliding component 17 is installed on the top of the chassis 16, and a support frame 18 is slidably installed at the bottom of the sliding component 17. A handle 19 is fixedly installed on the side of the support frame 18 to facilitate the operator to carry and move the support frame 18. A crossbar 22 is fixedly installed at the bottom of the support frame 18, and baffles 23 are rotatably installed on both sides of the crossbar 22. The baffles 23 are in contact with the chassis 16. When the support frame 18 is used to collect rubber granules, the baffles 23 can prevent the granules from falling out from the bottom of the support frame 18. When it is necessary to clean the support frame 18, the support frame 18 can be dragged to release the baffles 23 from the chassis 16, exposing the bottom space of the support frame 18, so that the rubber granules can be poured out easily.

[0036] Finally, see Figure 7In this embodiment, the sliding component 17 includes at least two slides 20. The slides 20 are fixedly arranged on both sides of the top of the chassis 16. The bottom of the support frame 18 is fixedly provided with sliding blocks 21 corresponding to the number of slides 20. The sliding blocks 21 are slidably arranged with the inner wall of the slides 20. With this design, the support frame 18 can slide smoothly on the slides 20, so that the operator can easily move the support frame 18 to a suitable position for collecting or cleaning rubber particles.

[0037] Working principle:

[0038] In operation, the waste rubber tire crushing device first activates the first motor 3 and the second motor 14. The first motor 3 drives the crushing blades 2 to rotate at high speed, providing power for crushing the waste rubber tires. The second motor 14 drives the reciprocating crankshaft 15 to rotate, causing the screen 11 to reciprocate within the grooves 10 around the support 1, preparing to screen the crushed material. The waste rubber tires are placed in the area where the crushing blades 2 can operate. The high-speed rotating crushing blades 2 cut and crush the tires from different angles and positions, breaking them into smaller rubber particles. During the crushing process, the crushing blades 2 can more flexibly contact all parts of the tire compared to traditional roller crushers, applying crushing force evenly and reducing incomplete crushing. The crushed rubber particles fall onto the screen 11. As the screen 11 reciprocates under the action of the reciprocating crankshaft 15, rubber particles that meet the aperture requirements of the screen 11 pass through the screen 11 and fall into the collection component 24 below. Larger particles that do not meet the requirements remain on the screen 11. Larger rubber particles on screen 11 are screened out by screening component 4 and fall into receiving frame 6. The particles in receiving frame 6 move upward along conveying pipe 7 under the action of auger 8 in conveying pipe 7. After reaching the top of conveying pipe 7, they enter conveying frame 9 and fall from conveying frame 9 to one end of crushing blade 2, returning to the crushing area of ​​crushing blade 2 for secondary crushing to ensure that all materials are fully crushed. Rubber particles that meet the requirements after screening fall into the carrying frame 18 of collecting component 24. When the carrying frame 18 has collected a certain amount of rubber particles, the operator holds the handle 19 on the side of the carrying frame 18 and slides it on the slide 20 through sliding block 21 to pull the carrying frame 18 out from the sliding component 17 at the bottom of the support 1. At this time, the baffles 23 on both sides of the bottom crossbar 22 of the carrying frame 18 are released from the chassis 16, and the rubber particles in the carrying frame 18 are poured out for further processing. After processing, the carrying frame 18 is pushed back to its original position, and the baffles 23 are rotated to make them fit with the chassis 16 to continue collecting rubber particles.
