Description

Technical Field

[0001] This utility model relates to the field of rubber granulation technology, and in particular to a high-yield and high-efficiency rubber granulation equipment. Background Technology

[0002] Rubber granulation technology is the process of processing waste rubber or raw rubber into uniform granules. The rubber granulation process includes the freeze granulation method, which is suitable for processing highly elastic or heat-sensitive rubber materials. The frozen and brittle rubber is fed into the granulation equipment for processing.

[0003] Existing rubber granulation equipment uses high-speed rotating blades or hammers to strike the granules. However, processing efficiency is affected by using only one mode. Combining the two generally requires different drive sources, which increases energy consumption.

[0004] Therefore, the existing rubber granulation equipment mentioned above, which uses high-speed rotating blades or hammers to strike the rubber, suffers from reduced processing efficiency in a single mode, and increased energy consumption when used in combination. This invention addresses this problem by using a drive motor to drive a combination shaft and crushing blades to rotate for granulation, while simultaneously driving the crushing block to swing left and right to collide and compress the incoming brittle rubber. The entire system is driven by a drive motor, improving efficiency and reducing energy consumption. Utility Model Content

[0005] To overcome the limitations of common rubber granulation equipment, which uses high-speed rotating blades or hammers to strike the pellets, a single mode affects processing efficiency, and combining these methods increases energy consumption.

[0006] The technical solution of this utility model is as follows: a high-yield and high-efficiency rubber granulation equipment, including a granulation box, a connecting pipe head is sealed and fixedly installed on the top frame of the granulation box, and a translation groove is opened on the middle frame of the granulation box, and a guide rod is fixedly installed in the translation groove. A support leg is fixedly installed on the outside of the granulation box. The interior of the granulation box is provided with a processing chamber, a guide chamber and a processing channel, and the height of the processing chamber, the guide chamber and the processing channel decreases sequentially. An inner pressure plate is embedded and fixedly installed on the inner wall of the granulation box, and a crushing block is installed between the inner pressure plates. The crushing block is located inside the processing chamber. A through hole is opened in the center of the crushing block, and a connecting block is fixedly installed on the outer surface of the crushing block. The connecting block is located inside the translation groove and is connected to the guide rod through the groove. A drive motor is fixedly installed on the top surface of the granulation box.

[0007] Preferably, the internal spaces of the processing chamber, the guiding chamber, and the processing channel are interconnected, and the processing chamber is interconnected with the internal space of the connecting pipe head, and the connecting pipe heads are symmetrically distributed at equal intervals on the granulation box.

[0008] Preferably, the outer surface of the inner pressure plate is flush with the inner wall of the granulation box, and there is a gap between the inner pressure plate and the crushing block, and the top outer side of the crushing block is set with an inclined structure.

[0009] Preferably, a drive shaft is fixedly installed at the bottom output end of the drive motor, and the drive shaft passes through a through hole. A cam is fixedly installed at the bottom end of the drive shaft, and the cam is located inside the swing frame. The swing frame is fixedly installed at the center of the bottom surface of the crushing block. A combined shaft is fixedly installed on the bottom surface of the cam, and a crushing blade is installed on the outer surface of the combined shaft. The crushing blade is located inside the processing channel.

[0010] Preferably, the diameter of the drive shaft is smaller than the diameter of the through hole, and the distance between the drive shaft and the inner wall of the through hole is greater than the distance between the inner pressure plate and the crushing block.

[0011] Preferably, the maximum top-view length of the cam is greater than the shortest distance between the inner walls of the swing frame, and the maximum distance between the inner walls of the swing frame is greater than the maximum top-view length of the cam.

[0012] Preferably, the crushing blade is connected to the combined shaft by embedding and fixing, and the crushing blades are distributed at equal angles on the combined shaft, with cutting edges provided on both sides of the crushing blades in the lateral direction.

[0013] The beneficial effects of this utility model are:

[0014] After being frozen and brittled, the rubber enters the processing chamber through the connecting pipe. It is then guided between the inner pressure plate and the crushing block by the inclined structure of the crushing block. The crushing block performs preliminary particle processing through compression and collision. After processing, the rubber is discharged into the processing channel through the guide chamber and then undergoes secondary particle processing by the high-speed rotating crushing blade, thereby improving the overall efficiency of rubber particle processing.

[0015] The drive motor drives the cam to rotate via the drive shaft. The cam moves the crushing block left and right repeatedly according to the swing frame, while simultaneously driving the combined shaft and the crushing blade to rotate at high speed, creating a linkage effect and reducing energy consumption.

[0023] 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.

[0024] Please see Figures 1-6 This utility model provides a technical solution: a high-yield and high-efficiency rubber granulation equipment, including a granulation box 1. A connecting pipe head 2 is sealed and fixedly installed on the top frame of the granulation box 1, and a translation groove 3 is opened on the middle frame of the granulation box 1. A guide rod 4 is fixedly installed in the translation groove 3. A support leg 5 is fixedly installed on the outside of the granulation box 1. The interior of the granulation box 1 is provided with a processing chamber 6, a guide chamber 7, and a processing channel 8. The height positions of the processing chamber 6, the guide chamber 7, and the processing channel 8 decrease sequentially. An inner pressure plate 9 is embedded and fixedly installed on the inner wall of the granulation box 1. A crushing block 10 is installed between the inner pressure plates 9. The crushing block 10 is located inside the processing chamber 6. A through hole 11 is opened in the center of the crushing block 10. A connecting block 12 is fixedly installed on the outer surface of the crushing block 10. The connecting block 12 is located inside the translation groove 3 and is connected to the guide rod 4. A drive motor 13 is fixedly installed on the top surface of the granulation box 1.

[0025] The internal spaces of the processing chamber 6, the guide chamber 7 and the processing channel 8 are interconnected, and the processing chamber 6 is also interconnected with the internal space of the connecting pipe head 2. The connecting pipe heads 2 are symmetrically distributed at equal intervals on the granulation box 1. External pipes can transport the frozen brittle rubber to the processing chamber 6 for processing through the connecting pipe heads 2.

[0026] The outer surface of the inner pressure plate 9 is flush with the inner wall of the granulation box 1, and there is a gap between the inner pressure plate 9 and the crushing block 10. The top outer side of the crushing block 10 is set with an inclined structure. The inclined structure on the crushing block 10 facilitates the entry of brittle rubber to slide between the crushing block 10 and the inner pressure plate 9, and to be crushed by the crushing block 10.

[0027] A drive shaft 14 is fixedly installed at the bottom output end of the drive motor 13, and the drive shaft 14 passes through the through hole 11. A cam 15 is fixedly installed at the bottom end of the drive shaft 14, and the cam 15 is located inside the swing frame 16. The swing frame 16 is fixedly installed at the center of the bottom surface of the crushing block 10. A combined shaft 17 is fixedly installed on the bottom surface of the cam 15, and a crushing blade 18 is installed on the outer surface of the combined shaft 17. The crushing blade 18 is located inside the processing channel 8. The diameter of the drive shaft 14 is smaller than the diameter of the through hole 11, and the distance between the drive shaft 14 and the inner wall of the through hole 11 is greater than the distance between the inner pressure plate 9 and the crushing block 10. This facilitates the rotation of the drive shaft 14 within the through hole 11. At the same time, the subsequent swinging and translational operation of the crushing block 10 will not affect the rotation of the drive shaft 14, thus avoiding collisions during the movement of the crushing block 10.

[0028] The maximum length of the cam 15 when viewed from above is greater than the shortest distance between the inner walls of the swing frame 16, and the maximum distance between the inner walls of the swing frame 16 is greater than the maximum length of the cam 15 when viewed from above. This makes it convenient for the cam 15 to rotate and push the swing frame 16 to move left and right, thereby driving the crushing block 10 to perform swinging and collision processing.

[0029] The crushing blade 18 is connected to the combined shaft 17 by embedding and fixing. The crushing blades 18 are evenly distributed on the combined shaft 17, and cutting edges are provided on both sides of the lateral direction of the crushing blade 18. The combined shaft 17 can drive the crushing blade 18 to rotate. Depending on the structure and distribution of the crushing blade 18, it can operate in different directions and perform processing work.

[0030] Working principle: According to Figures 1-2 First, after the granulation box 1 is placed stably by the support legs 5, the external conveying pipe and the connecting pipe head 2 can be assembled and sealed to transport the frozen brittle rubber into the processing chamber 6.

[0031] according to Figures 1-6Simultaneously, the drive motor 13 is connected to an external power source via a power cord and started. The drive motor 13 is a known and existing technology on the market and will not be described in detail here. The drive motor 13 drives the cam 15 to rotate via the drive shaft 14. The cam 15 can push the swing frame 16 to swing left and right. The swing frame 16 drives the crushing block 10 to swing left and right. The crushing block 10 drives the connecting block 12 to slide smoothly on the guide rod 4, improving the stability during operation. At the same time, the cam 15 drives the combined shaft 17 and the crushing blade 18 to rotate. The crushing blade 18 rotates at high speed in the processing channel 8. The brittle rubber in the processing chamber 6 can be guided to the gap between the inner pressure plate 9 and the crushing block 10 through the inclined structures on both sides of the top of the crushing block 10. The crushing block 10 is squeezed and crushed into particles through its swing. The processed material can be quickly discharged into the processing channel 8 through the guide chamber 7. It undergoes secondary particle processing through the high-speed rotating crushing blade 18 and is discharged from the bottom of the subsequent processing channel 8, improving processing efficiency and reducing energy consumption.

[0032] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
