Description

Technical Field

[0001] This utility model relates to the technical field of reclaimed rubber raw material crushing equipment, specifically, to a multi-stage crushing equipment for reclaimed rubber raw materials. Background Technology

[0002] Reclaimed rubber is a material that has been reprocessed from waste rubber products and has certain rubber properties. It is of great significance in resource recycling and industrial production.

[0003] After waste rubber is collected, it is first sorted and washed to remove surface impurities and sediment. Next, a crushing process breaks the waste rubber into smaller particles. Then, chemical and physical methods, such as high temperature, high pressure, and the addition of softeners and activators, are used to break the molecular chains of the vulcanized rubber, disrupting its original cross-linked structure and restoring its plasticity and elasticity. Finally, after refining and filtration, the finished reclaimed rubber is produced. However, existing reclaimed rubber raw material crushing equipment generally suffers from low crushing efficiency and poor crushing effect. Most equipment only has a single crushing function and cannot perform fine processing of reclaimed rubber raw materials, resulting in uneven particle size after crushing, which fails to meet the high-quality requirements of subsequent processing. Furthermore, some equipment is prone to material blockage during prolonged use, affecting normal operation and production efficiency. In addition, the equipment's structural design is not reasonable, making installation and maintenance inconvenient and increasing operating costs and labor intensity. Therefore, a new type of reclaimed rubber raw material crushing equipment is urgently needed to solve the above problems. Utility Model Content

[0004] This utility model provides a multi-stage crushing device for reclaimed rubber raw materials, which adopts a two-stage crushing structure. In the first-stage crushing chamber, the first rotating roller drives the crushing blades to perform preliminary crushing of the reclaimed rubber raw materials. The crushed material enters the second crushing chamber, where it is further crushed by the second crushing spiral cutter head on the second rotating roller, which effectively improves the crushing efficiency. The stirring and anti-clogging component uses the rotation of the third pulley to drive the connecting rod to move up and down. The stirring rod stirs the material to prevent accumulation, and the anti-clogging rod pushes the material to prevent the discharge port from being blocked, effectively avoiding the accumulation of material in the second crushing chamber and the blockage of the discharge port.

[0005] A multi-stage crushing device for reclaimed rubber raw materials includes a support frame. A lower cavity and an upper cavity are fixedly connected to the upper part of the support frame. The upper and lower cavities are connected to each other to form a primary crushing chamber. Fixed side strips are fixedly connected to both sides of the upper and lower cavities, and the opposing fixed side strips are locked together by bolts and nuts. One end of the upper cavity is fixedly connected to a feeding channel for feeding materials. Semicircular grooves for a first rotating roller to pass through are respectively provided in the middle of opposite sides of both ends of the lower and upper cavities. The opposing semicircular grooves enclose a circular hole. Both ends of the first rotating roller are rotatably connected to the support frame. A set of evenly arranged crushing blades is fixedly connected to the portion of the first rotating roller within the primary crushing chamber. Several evenly arranged discharge holes are opened in the lower part of the lower cavity. A second crushing chamber is fixedly connected to the lower cavity, and the discharge holes correspond to the feeding end of the second crushing chamber. A second rotating roller is arranged inside the second crushing chamber and rotatably connected to the second crushing chamber. A set of evenly arranged second crushing spiral cutters is fixedly arranged on the second rotating roller.

[0006] Furthermore, both the first and second rotating rollers are connected to a drive assembly.

[0007] Furthermore, the drive assembly includes a motor, a first pulley, a second pulley, and a third pulley. The first pulley fixes one end of the first rotating roller. The first pulley is connected to the second pulley via a first belt drive. The center of the second pulley is fixedly connected to the output shaft of the motor. The motor is fixedly connected to the bracket. The second pulley is connected to the third pulley via a second belt drive. The center of the third pulley is fixedly connected to the second rotating roller.

[0008] Furthermore, a screen plate is fixedly installed inside the second crushing chamber, and the diameter of the through hole of the screen plate is smaller than the diameter of the discharge hole.

[0009] Furthermore, it also includes a stirring and anti-clogging component, which is used to stir the material in the second crushing chamber and push the material at the outlet of the second crushing chamber. The stirring and anti-clogging component includes a chute, which is fixed to one side of the second crushing chamber. A slider is slidably connected in the chute. One end of the slider is rotatably connected to a connecting rod, and the other end of the connecting rod is rotatably connected to a rotating shaft. The rotating shaft is fixed to one edge of the third pulley. A connecting rod is fixedly connected to the lower end of the slider. The connecting rod is U-shaped, and the other end of the connecting rod is inside the second crushing chamber. The other end of the connecting rod slides through one end of the screen plate. A set of evenly arranged stirring rods is fixedly connected to the area above the screen plate, and a set of evenly arranged anti-clogging rods is fixedly connected to the area below the screen plate.

[0010] Furthermore, the second crushing chamber is inclined, and the outlet of the second crushing chamber is lower than the inlet.

[0011] Furthermore, screw rods are screwed to the four corners of the bracket, and the lower ends of the screw rods are fixedly connected to the support blocks.

[0012] Compared with the prior art, the advantages and beneficial effects of this utility model are: The system employs a two-stage crushing structure. In the first-stage crushing chamber, the first rotating roller drives the crushing blades to initially crush the reclaimed rubber raw material. The crushed material then enters the second crushing chamber, where it is further crushed by the second crushing spiral cutter head on the second rotating roller, effectively improving the crushing efficiency. The first and second rotating rollers are connected by a drive assembly consisting of a motor, pulleys, and a belt. The belt drive method is simple in structure, low in cost, and easy to maintain, ensuring the normal operation of both rotating rollers and guaranteeing the continuity and stability of the crushing process. The screen plate installed in the second crushing chamber has a through hole diameter smaller than the discharge hole diameter, which can screen the crushed material, control the particle size of the crushed material, and make the discharge more uniform. The stirring and anti-clogging component uses the rotation of the third pulley to drive the connecting rod to move up and down. The stirring rod stirs the material to prevent accumulation, and the anti-clogging rod pushes the material to prevent the discharge port from being blocked, effectively avoiding the accumulation of material in the second crushing chamber and the blockage of the discharge port. The second crushing chamber is inclined, with the outlet lower than the feed inlet, which makes it easier for the material to flow and be discharged under the action of gravity, reducing the residence time of the material in the chamber and further improving the crushing efficiency. It also helps to prevent material accumulation. The screws and support blocks at the four corners of the bracket can adjust the level and height of the equipment, enabling it to adapt to different ground environments, maintain stable operation, and facilitate installation and commissioning.

[0015] To clearly illustrate the technical features of this solution, the present invention will be described in detail below through specific embodiments and in conjunction with the accompanying drawings. In the description of this invention, it should be noted that the terms "left," "right," "front," "rear," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing the invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0016] The following is in conjunction with the appendix Figures 1-5 The present invention will be further described in terms of the embodiments and implementation methods.

[0017] The specific embodiments of this utility model are as follows: A multi-stage crushing device for reclaimed rubber raw materials includes a support frame 4. A lower cavity 101 and an upper cavity 1 are fixedly connected to the upper part of the support frame 4. The upper cavity 1 and the lower cavity 101 are connected to each other to form a primary crushing chamber. Fixed side strips 17 are fixedly connected to both sides of the upper cavity 1 and the lower cavity 101, and the opposing fixed side strips 17 are locked together by bolts and nuts. One end of the upper cavity 1 is fixedly connected to a feeding channel 2 for feeding materials. Semicircular grooves for a first rotating roller 19 to pass through are respectively provided in the middle of opposite sides of both ends of the lower cavity 101 and the upper cavity 1. The opposing semicircular grooves enclose a circular hole. The first rotating roller 19 is rotatably connected to the bracket 4 at both ends. A set of uniformly arranged crushing blades 18 are fixedly connected to a portion of the first rotating roller 19 within the primary crushing chamber. A plurality of uniformly arranged discharge holes are provided at the lower part of the lower chamber 101. The lower chamber 101 is fixedly connected to the second crushing chamber 13. The discharge holes correspond to the feed end of the second crushing chamber 13. A second rotating roller 20 is provided inside the second crushing chamber 13. The second rotating roller 20 is rotatably connected to the second crushing chamber 13. A set of uniformly arranged second crushing spiral cutter heads 27 are fixedly provided on the second rotating roller 20.

[0018] The lower cavity 101 and the upper cavity 1 are supported by the bracket 4, and the two are connected to form a primary crushing cavity. The cavity is fixed by the fixing strip 17 and bolts and nuts. The reclaimed rubber raw material enters the primary crushing cavity from the feed channel 2. The first rotating roller 19 drives the crushing blade 18 to rotate, which performs preliminary crushing of the raw material. The crushed material falls into the second crushing cavity 13 through the discharge hole of the lower cavity 101. The second crushing spiral cutter head 27 on the second rotating roller 20 further crushes the material, realizing two-stage crushing of the reclaimed rubber raw material, improving crushing efficiency and crushing effect, making the raw material more uniform and fine, and providing a good foundation for subsequent processing. The design of the primary crushing cavity is easy to install and disassemble, and convenient to maintain and replace parts.

[0019] Both the first rotating roller 19 and the second rotating roller 20 are connected to the drive assembly.

[0020] The first rotating roller 19 and the second rotating roller 20 are connected by a drive assembly. The drive assembly provides power to the rotating rollers, enabling them to rotate, thereby driving the crushing blade 18 and the crushing spiral head to work, ensuring that the first rotating roller 19 and the second rotating roller 20 can operate normally, and ensuring the continuity and stability of the crushing process.

[0021] The drive assembly includes a motor 5, a first pulley 3, a second pulley 6, and a third pulley 14. The first pulley 3 is fixed to one end of the first rotating roller 19. The first pulley 3 is connected to the second pulley 6 via a first belt 25. The center of the second pulley 6 is fixedly connected to the output shaft of the motor 5. The motor 5 is fixedly connected to the bracket 4. The second pulley 6 is connected to the third pulley 14 via a second belt 26. The center of the third pulley 14 is fixedly connected to the second rotating roller 20.

[0022] The drive assembly consists of a motor 5, a first pulley 3, a second pulley 6, a third pulley 14, a first belt 25, and a second belt 26. The rotation of the motor 5 drives the second pulley 6 to rotate, which in turn drives the first pulley 3 via the first belt 25, causing the first rotating roller 19 to rotate. At the same time, the second pulley 6 drives the third pulley 14 via the second belt 26, causing the second rotating roller 20 to rotate. The belt drive method is simple in structure, low in cost, and easy to maintain, and can achieve simultaneous rotation of the first rotating roller 19 and the second rotating roller 20.

[0023] A screen plate 24 is fixedly installed inside the second crushing chamber 13, and the diameter of the through hole of the screen plate 24 is smaller than the diameter of the discharge hole.

[0024] The screen plate 24 inside the second grinding chamber 13 screens the ground material. Material smaller than the diameter of the through hole of the screen plate 24 passes through the screen plate 24, while material larger than the diameter of the through hole continues to be ground in the second grinding chamber 13. This controls the particle size of the ground material. The diameter of the through hole of the screen plate 24 is smaller than the diameter of the discharge hole, ensuring that the material after primary grinding can enter the second grinding chamber 13 for further grinding and avoiding the direct discharge of large particles.

[0025] It also includes a stirring and anti-clogging component, which is used to stir the material in the second crushing chamber 13 and push the material at the outlet of the second crushing chamber 13. The stirring and anti-clogging component includes a chute 9, which is fixed to one side of the second crushing chamber 13. A slider 11 is slidably connected in the chute 9. One end of the slider 11 is rotatably connected to a connecting rod 12. The other end of the connecting rod 12 is rotatably connected to a rotating shaft 15. The rotating shaft 15 is fixed to one edge of the third pulley 14. A connecting rod 10 is fixedly connected to the lower end of the slider 11. The connecting rod 10 is U-shaped. The other end of the connecting rod 10 is inside the second crushing chamber 13. The other end of the connecting rod 10 slides through one end of the screen plate 24. A set of evenly arranged stirring rods 22 are fixedly connected to the upper area of ​​the screen plate 24. A set of evenly arranged anti-clogging rods 23 are fixedly connected to the lower area of ​​the screen plate 24.

[0026] When the third pulley 14 rotates, it drives the rotating shaft 15 to rotate, and through the connecting rod 12, it causes the slider 11 to slide in the groove 9, thereby driving the connecting rod 10 to move up and down. The stirring rod 22 on the connecting rod 10 stirs the material on the upper side of the screen plate 24 to prevent material accumulation; the anti-clogging rod 23 pushes the material on the lower side of the screen plate 24 to prevent the discharge port from being blocked. The stirring and anti-clogging component can effectively prevent the material from accumulating in the second crushing chamber 13 and the discharge port from being blocked.

[0027] The second crushing chamber 13 is inclined, and its outlet is lower than its inlet. Under the influence of gravity, the material moves more easily from the inlet to the outlet, facilitating its flow and discharge within the second crushing chamber 13, reducing its residence time, improving crushing efficiency, and preventing material accumulation.

[0028] The bracket 4 is screwed with screw rods 7 at each of its four corners, and the lower end of each screw rod 7 is fixedly connected to a support block 8. By adjusting the height of the screw rods 7, the levelness and height of the equipment can be adjusted, allowing the equipment to adapt to different ground environments and maintain stable operation.

[0029] The motor 5 is electrically connected to a power source and a switch (the power source and switch are existing technologies and will not be described in detail or shown in the figure).

[0030] The method of using this utility model is as follows: Place the equipment in a suitable working area. Adjust the level and height of the equipment by adjusting the screws 7 at the four corners of the bracket 4 and using the support blocks 8 to ensure the equipment is stable. Connect the power supply and start the motor 5. Feed the reclaimed rubber raw material into the primary crushing chamber through the feed channel 2. The first rotating roller 19 drives the crushing blades 18 to rotate, which performs preliminary crushing of the raw material. The material after preliminary crushing falls into the second crushing chamber 13 through the discharge hole of the lower chamber 101. The second crushing spiral cutter head 27 on the second rotating roller 20 further crushes the material. In the second crushing chamber 13, the screen plate 24 screens the crushed material. The material that meets the particle size requirements is discharged through the screen plate 24, and the material that does not meet the requirements continues to be crushed. At the same time, the stirring and anti-blocking components continue to work. The stirring rod 22 stirs the material to prevent accumulation, and the anti-blocking rod 23 pushes the material to prevent the discharge port from being blocked. After the crushing work is completed, turn off the motor 5 and disconnect the power supply.

[0031] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
