Description

Technical Field

[0001] This utility model relates to the field of refining technology for recycled rubber, and in particular to a refining machine for recycled rubber. Background Technology

[0002] Reclaimed rubber is a rubber material with certain reusable value obtained from waste rubber products (such as waste tires, hoses, and belts) through a series of processes. A reclaimed rubber refining machine is a piece of equipment used for deep processing of reclaimed rubber. The purpose of the reclaimed rubber refining machine is to further improve the performance of reclaimed rubber and make its quality closer to that of natural or synthetic rubber.

[0003] Reclaimed rubber refining mills primarily operate through mechanical shearing force. Inside the machine are two opposing rotating rollers with special patterns or grooves on their surfaces. When reclaimed rubber is fed between these rollers, it generates a powerful shearing force. This shearing force further breaks down and disperses impurities and insufficiently desulfurized hard particles in the rubber, while simultaneously improving the orientation and alignment of the rubber molecular chains. This reduces the Mooney viscosity of the rubber and enhances its plasticity and uniformity.

[0004] In existing technologies, some refining machines use rollers to shear waste rubber products. The distance between the two rollers is fixed, which cannot be used to cut rubber products of different sizes. During the cutting process, if the gap between the rollers is too large, small rubber products will not receive enough shearing force and will not achieve the refining effect; if the gap is too small, large rubber products will be easily over-compressed, which will lead to equipment overload and affect the quality of the rubber. Therefore, a reclaimed rubber refining machine is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a reclaimed rubber refining machine, which aims to improve the problem that the spacing between the rollers of some existing refining machines cannot be used to cut and refine rubber products of different sizes.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A reclaimed rubber refining machine includes a base. Support frames are fixedly connected to the left and right sides of the top of the base. A motor is fixedly connected to the outside of the right support frame. A transmission rod is fixedly connected to the drive end of the motor. A bevel gear is slidably connected to the front end of the transmission rod. A bevel gear is fixedly connected to the rear end of the transmission rod. Slide plates are fixedly connected to the outside of both bevel gears. Connecting blocks are fixedly connected to the left and right sides of the top of the slide plates. A transmission rod is rotatably connected to the adjacent side of the connecting blocks. A bevel gear is fixedly connected to the left end of the transmission rod. A guide block is fixedly connected to the outside of the right transmission rod. A guide rail is fixedly connected to the front end of the right support frame. Support blocks are fixedly connected to the adjacent front ends of the two support frames. A shock-absorbing buffer assembly is fixedly connected to the bottom of the base.

[0008] As a further description of the above technical solution:

[0009] The buffer assembly includes multiple telescopic rods, the top ends of which are fixedly connected to the outer bottom end of the base. Springs are sleeved on the outside of each telescopic rod, and support legs are fixedly connected to the bottom end of each telescopic rod.

[0010] As a further description of the above technical solution:

[0011] A collection tray is fixedly connected to the bottom of the base. A baffle is slidably connected inside the collection tray. A feed pipe is fixedly connected to the rear end of the collection tray. A fixing block is fixedly connected to the rear end of the base. A motor is fixedly connected to the bottom of the fixing block. A sleeve rod is fixedly connected inside the fixing block. An auger is rotatably connected inside the sleeve rod. A feed port is fixedly connected to the top end of the sleeve rod.

[0012] As a further description of the above technical solution:

[0013] The top outer end of each support frame is fixedly connected to a support rod, and an inlet is fixedly connected to the outer side of the support rod. An electric push rod is fixedly connected inside the support block, and the drive end of the electric push rod is fixedly connected to the outer front end of the front slide plate.

[0014] As a further description of the above technical solution:

[0015] The external rotatable connection of the first transmission rod is to the inside of the left-side bearing frame, and the external slidable connection of the first bevel gear is to the inside of the left-side bearing frame;

[0016] As a further description of the above technical solution:

[0018] As a further description of the above technical solution:

[0019] The guide block is internally slidably connected to the inside of the guide rail, and the transmission rod 2 is externally fixedly connected to rollers;

[0020] As a further description of the above technical solution:

[0021] The other end of the feed pipe is fixedly connected to the inside of the sleeve rod, and the drive end of the second motor is fixedly connected to the bottom of the auger.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the two rollers are driven by a motor to shear the rubber, while an electric push rod pushes a sliding plate. The roller spacing is adjusted by the sliding of the guide block on the guide rail. It can be flexibly adjusted according to the size of the rubber product. For small rubber products, the roller spacing can be reduced so that it can be subjected to appropriate shearing force to ensure the refining effect. For large rubber products, the spacing can be appropriately increased to avoid excessive compression, prevent equipment overload, and ensure rubber quality. This greatly improves the adaptability and processing capacity of the equipment for waste rubber products of different specifications.

[0024] 2. In this utility model, the rubber after the first refining falls into the collection tray for collection. By pulling the baffle, the rubber enters the sleeve rod, and then the motor is started to transport it in conjunction with the auger. It then enters the drum again from the feeding port for refining, so that the rubber can be refined multiple times. During the multiple refining process, the molecular structure of the rubber can be adjusted and optimized more evenly, so that the final recycled rubber has better consistency in quality, and the various performance indicators are more stable and reliable, thereby improving the market competitiveness of the product.

[0031] 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.

[0032] Reference Figures 1 to 3 This utility model provides an embodiment of a recycled rubber refining machine, including a base 1. The base 1 is the basic support structure of the entire refining machine, providing a stable and secure mounting platform for components such as the upper support frame 2 and motor 3. Support frames 2 are fixedly connected to the left and right sides of the top of the base 1. The support frames 2 are used to support and fix the core transmission and working components of the refining machine, such as the transmission rod 4, slide plate 7, and roller 15, providing mounting positions and motion guidance for these components, ensuring the coordination between the components, and enabling the refining operation to proceed in an orderly and stable manner. A motor 3 is fixedly connected to the outside of the side support frame 2. The motor 3 provides a power source for the rotation of the transmission rod 4. The drive end of the motor 3 is fixedly connected to the transmission rod 4, which transmits the rotational power output by the motor 3 to the bevel gear 5 and the bevel gear 6. The outer front end of the transmission rod 4 is slidably connected to the bevel gear 5. The bevel gear 5 cooperates with the transmission rod 4 and the bevel gear 10. When it meshes with the bevel gear 10, it changes the direction of power transmission and drives the transmission rod 9 to rotate, thereby driving the connected roller 15 to rotate, realizing the shearing and refining operation of the rubber.

[0033] A bevel gear 6 is fixedly connected to the outer rear end of transmission rod 4. Bevel gear 6 has the same effect as bevel gear 5, being fixedly connected to the rear end of transmission rod 4. When meshing with bevel gear 10, it can drive transmission rod 9 and roller 15 to rotate in opposite directions. Slide plates 7 are fixedly connected to the outer sides of both bevel gear 5 and bevel gear 6. Slide plates 7 are the connecting carriers of bevel gear 5 and bevel gear 6, not only fixing them and allowing them to move with their own rotation, but also providing a rotation fulcrum for transmission rod 9 through the connecting block 8 at the top. Connecting blocks 8 are fixedly connected to the left and right sides of the top of slide plate 7. Connecting blocks 8 are used to connect slide plate 7 and transmission rod 9. Transmission rod 9 is rotatably connected to the outer side of the connecting block 8. Transmission rod 9 receives power from the transmission rod through the meshing of bevel gear 10 with bevel gear 5 or bevel gear 6. The power of the first rod 4 is transmitted to itself, thereby driving the external roller 15 to rotate, realizing the direct shearing and refining action of the rubber. The outer left end of the transmission rod 2 9 is fixedly connected to the bevel gear 3 10. The bevel gear 3 10 meshes with the bevel gear 1 5 and the bevel gear 2 6 respectively to realize the change and transmission of power direction. The rotational power from the transmission rod 4 is transmitted to the transmission rod 2 9 in a suitable direction, thereby driving the roller 15 to perform forward and reverse operation. The outer side of the right transmission rod 2 9 is fixedly connected to the guide block 11. When the electric push rod 14 pushes the slide plate 7 to move, the guide block 11 slides inside the guide rail 12, providing guidance and limiting function for the movement of the transmission rod 2 9, ensuring that the transmission rod 2 9 moves only along the predetermined straight line direction during the adjustment of the roller 15 spacing, avoiding deviation or shaking caused by lateral forces and other factors.

[0034] A guide rail 12 is fixedly connected to the front end of the right-side support frame 2, providing a stable sliding track for the guide block 11. A support block 13 is fixedly connected to the front end of the two support frames 2 on their adjacent sides. The support block 13 provides a stable installation and support structure for the electric push rod 14. The electric push rod 14 is fixedly connected inside the support block 13. Activating the electric push rod 14 pushes the slide plate 7 to slide between the support blocks 13, realizing the position switching between bevel gear 1 5 and bevel gear 2 6 and the adjustment of the distance between the rollers 15. The drive end of the electric push rod 14 is fixedly connected to the front end of the front slide plate 7. A shock-absorbing buffer assembly is fixedly connected to the bottom end of the base 1. The buffer assembly includes multiple telescopic rods 16. The telescopic rod 16 can limit the excessive displacement of the base 1. The top ends of multiple telescopic rods 16 are fixedly connected to the bottom of the base 1. A spring 17 is sleeved on the outside of the telescopic rod 16. When the equipment is subjected to impact force, the spring 17 will be compressed and deformed by the downward pressure of the base 1, converting the impact energy into elastic potential energy and storing it. As the impact energy weakens, the spring 17 will rebound and release the elastic potential energy, pushing the base 1 back to the initial position, thereby achieving the effect of buffering and shock absorption. The bottom end of the telescopic rod 16 is fixedly connected to the support leg 18, which provides stable support for the telescopic rod 16 and the spring 17, ensuring that the buffer assembly can perform its shock absorption and buffering function normally.

[0035] Reference Figure 1 , Figure 2 , Figure 4 The top of the outer side of the support frame 2 is fixedly connected to a support rod 19. The outer side of the support rod 19 is fixedly connected to a feed inlet 20. The feed inlet 20 is the entrance for the rubber raw material to enter the refining machine. The bottom of the base 1 is fixedly connected to a collection tray 21. The collection tray 21 is used to process the refined rubber. The inside of the collection tray 21 is slidably connected to a baffle 22. During normal refining, the baffle 22 is in the closed state to prevent the material in the collection tray 21 from entering the feed pipe 23 too early. When multiple refining is required, the feed pipe 23 can be exposed by pulling the baffle 22, so that the rubber material in the collection tray 21 can smoothly enter the feed pipe 23 for circulating refining.

[0036] The inner rear end of the collecting tray 21 is fixedly connected to the feed pipe 23, and the outer rear end of the base 1 is fixedly connected to the fixing block 24. The bottom end of the fixing block 24 is fixedly connected to the motor 25, which provides the power source for the auger 27. The fixing block 24 is fixedly connected to the sleeve rod 26, which is the conveying channel for rubber materials and the mounting carrier for the auger 27. The auger 27 is rotatably connected inside the sleeve rod 26, which pushes the rubber materials entering the sleeve rod 26 from the feed pipe 23 upward along the axial direction. The outer top end of the sleeve rod 26 is fixedly connected to the feeding port 28, which is the transition channel for the rubber materials to enter the feed port 20 from the sleeve rod 26.

[0037] Working principle: When motor 3 starts, it drives transmission rod 4 to rotate. The rotation of transmission rod 4 causes bevel gear 5 and bevel gear 6 to rotate accordingly. Since bevel gear 5 and bevel gear 6 are both fixedly connected to the slide plate 7, and bevel gear 5 is slidably connected to the front end of transmission rod 4, while bevel gear 6 is fixedly connected to the rear end of transmission rod 4, during the rotation of slide plate 7, the drive end of electric push rod 14 extends and retracts, causing the front slide plate 7 to slide between support blocks 13, thereby changing the positional relationship between bevel gear 5 and bevel gear 6. When bevel gear 5 meshes with bevel gear 10, bevel gear 5 drives bevel gear 10 to rotate. The rotation of bevel gear 10 drives the transmission rod 9 connected to it to rotate. The rotation of transmission rod 9 drives the external roller 15 to rotate. When bevel gear 6 meshes with bevel gear 10, bevel gear 6 drives bevel gear 10 to rotate in the opposite direction, thereby causing transmission rod 9 to drive roller 15 to rotate relative to each other for refining the rubber. Then, the electric push rod 14 is activated to push the front slide plate 7, which in turn causes the guide block 11 to slide on the guide rail 12, thereby driving the front roller 15 to adjust the spacing.

[0038] The refined rubber falls into the collection tray 21. When multiple refining processes are required, the baffle 22 is pulled to expose the feed pipe 23. The rubber then enters the sleeve rod 26 through the feed pipe 23. Subsequently, the motor 25 is started, driving the auger 27 to rotate inside the sleeve rod 26. The rotation of the auger 27 conveys the rubber material upwards, through the loading port 28, into the feed inlet 20. The feed inlet 20 is fixed to the top of the support frame 2 by the support rod 19. After entering, the material is refined multiple times between the rollers 15. If the equipment vibrates, the buffer assembly consisting of the telescopic rod 16 and the spring 17 at the bottom of the base 1 takes effect. The spring 17 is compressed or rebounded under force, which, together with the extension and retraction of the telescopic rod 16, provides a shock absorption effect. The support leg 18 provides support for the entire device.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
