By providing the explosion-proof isolation structure, it has a blocking effect on the dust generated during the operation of the granulation unit and the transmission unit, effectively avoiding the spread of dust during the production process and improving the use safety.

[0004] Among them, the rollers of the granulation unit and the crushing rollers in the crushing assembly are connected by a sprocket and a chain to achieve synchronous transmission. Although this can save the drive source, when the granulation roller needs to be disassembled for maintenance or replacement, it is necessary to remove both the driving sprocket and the chain, which is troublesome to operate. Summary of the Utility Model

[0017] In summary, the present application includes at least one of the following beneficial technical effects:

[0018] 1. By setting up an additional independent bearing seat and connecting it with the shaping roller by means of a transmission shaft, when the shaping roller needs to be disassembled, it is only necessary to release the connection between the transmission shaft and the shaping roller, without removing the sprocket and chain used for transmission, which effectively improves the convenience of disassembly and assembly and facilitates the installation and disassembly of the shaping roller;

[0019] 2. The connection and transmission between the transmission shaft and the shaping roller are realized by means of the connecting sleeve. The plug-in grooves at both ends of the connecting sleeve are plugged into the transmission shaft and the shaping roller. The axial movement can realize disassembly and assembly, which is convenient and fast.

[0020] 3. The connecting sleeve adopts a metal sleeve, which is low in cost and a disposable vulnerable part. Its structural strength is not high. When the shaping roller has difficulty in running due to the blockage of the screen, the metal sleeve will be damaged due to the force and the transmission state will be disconnected in time to avoid damage caused by continuous forced operation of the equipment, which plays a role in insurance and improving safety.

[0021] 4. The design of the annular groove effectively reduces the wall thickness of the connecting sleeve, making it easier for the connecting sleeve to break at this point under stress, further ensuring the timeliness of disconnecting the transmission state at the connecting sleeve in case of an accident and reducing the corresponding fault losses.

Detailed Description of the Embodiments

[0028] The following further describes the present application in Figures 1-4 detail with reference to the attached drawings.

[0029] Embodiment 1

[0030] A granulator, as Figure 1 shown in Figure 2 and

[0031] shown in Figure 1 and Figure 2 includes a machine body 1, a reducer 2, a granulation mechanism 3 and a shaper 4. A driving motor 5 is arranged at the bottom of the machine body 1. The output end of the driving motor 5 is connected and driven to the input end of the reducer 2 through a pulley and a belt. The output end of the reducer 2 is connected to the granulation mechanism 3. In this embodiment, the granulation mechanism 3 includes two granulation rollers 6 arranged in parallel. The surface of the granulation roller 6 is densely distributed with corresponding granulation holes. The end of the granulation roller 6 is connected to the output end of the reducer 2. Granulation is achieved by driving the two granulation rollers 6 to rotate towards each other. The shaper 4 is located below the granulation mechanism 3. The material after granulation falls into the shaper 4 and is scattered, and finally falls through the sieve mesh 10 for screening.As shown in the figure, the shaper 4 includes a main body 7 and shaping rollers 8. There are two shaping rollers 8 arranged horizontally at intervals. The shaping rollers 8 are rotatably connected to the main body 7. The surface of the shaping rollers 8 has evenly distributed shaping bars for breaking up the material. The main body 7 includes bearing plates 9 and a sieve mesh 10. The bearing plates 9 are located at both ends and are fixedly connected to the machine body 1. The sieve mesh 10 is fixed on the bearing plates 9. The sieve mesh 10 surrounds the opposite two sides and the bottom surface of the shaping rollers 8. The sieve mesh 10 is densely provided with sieve holes 11 for filtering out material particles. Bearings are provided at the rotational connection positions of the bearing plates 9 corresponding to the shaping rollers 8 to improve the smoothness of rotation.

[0032] As Figure 1 and Figure 2 As shown in the figure, a bearing seat 12 is fixedly provided below the machine body 1 corresponding to the reducer 2. The top of the bearing seat 12 is provided with a mounting hole 13 and is fixed to the machine body 1 by screws. A transmission shaft 14 is horizontally rotatably connected to the bearing seat 12. One end of the transmission shaft 14 is rotatably connected to the bearing seat 12, and the other end is detachably connected to the end of one of the shaping rollers 8. The end of the shaping roller 8 passes through the bearing plate 9 and is connected to the transmission shaft 14. The bearing seat 12 is located outside the main body 7 and bearings are also provided inside to improve the smoothness of rotation. The transmission shaft 14 has a transmission mounting position 15, and a sprocket 16 is fixedly installed on the transmission mounting position 15. A sprocket 16 is also provided at the end of one of the granulating rollers 6. A chain 17 for connecting and driving the two sprockets 16 is provided between the two sprockets 16. In this way, the power transmission is synchronously realized. When the granulating roller 6 rotates, the shaping roller 8 is synchronously driven to rotate. And in this embodiment, the sprocket 16 and the chain 17 are connected to the transmission shaft 14. In this way, when it is necessary to disassemble and assemble the shaping roller 8, only the connection between the transmission shaft 14 and the shaping roller 8 needs to be released, and the disassembly and assembly of the sprocket 16 and the chain 17 are not required, effectively improving the disassembly and assembly efficiency and facilitating the overall disassembly, replacement and operation of the shaping roller 8.

[0033] As Figures 1-3As shown, a connecting sleeve 18 for connecting the transmission shaft 14 and the end of the shaping roller 8 is provided between the transmission shaft 14 and the end of the shaping roller 8. The two ends of the connecting sleeve 18 have insertion slots 19, and the ends of the transmission shaft 14 and the shaping roller 8 have insertion ends adapted to the insertion slots 19. The circumferential linkage of the transmission shaft 14 and the shaping roller 8 is realized by the insertion connection method at both ends of the connecting sleeve 18. The cross-section of the slot opening of the insertion slot 19 is polygonal, which is a quadrilateral in this embodiment. And the connecting sleeve 18 is specifically hollow inside and is a metal sleeve, and the specific material is carbon steel. The middle part of the outer wall of the connecting sleeve 18 has an inwardly concave annular groove 20. In this way, the connecting sleeve 18 has a low cost and can be used as a disposable vulnerable part. Moreover, the overall structural strength of the connecting sleeve 18 is not high. When the screen 10 is blocked, resulting in an increase in the rotational resistance of the shaping roller 8, the connecting sleeve 18 is damaged under force and the transmission state is disconnected, timely cutting off the power source to avoid the situation that the shaping roller 8 is forced to rotate, resulting in serious failure and damage of the entire equipment, achieving a good insurance and protection effect. The design of the annular groove 20 makes the wall thickness of the connecting sleeve 18 thinner at this place, and it is more likely to break under force, further ensuring the timeliness of cutting off the transmission state. The inside of the connecting sleeve 18 is hollow, and at the corresponding annular groove 20, it is a deformation cavity, that is, there is a gap between the two ends of the insertion ends after being matched with the insertion slots 19. This gap is the deformation cavity corresponding to the annular groove 20. The deformation cavity gives the connecting sleeve 18 space for deformation under force, making it more convenient to break and cut off the power transmission in a timely manner under the stressed state.

[0034] As Figure 1 and Figure 2 shown, at the ends of the two shaping rollers 8, there are first transmission gears 21 that mesh with each other. With the help of the first transmission gears 21, the synchronous rotation of the two shaping rollers 8 can be realized to improve the shaping and dispersing effect. At the ends of the two granulating rollers 6 away from the reducer 2, there are second transmission gears 22 that mesh with each other. With the help of the second transmission gears 22, the synchronous opposite rotation of the two granulating rollers 6 is realized, effectively saving the drive source and achieving granulation, and achieving the corresponding energy-saving and equipment cost reduction purposes. In addition, a protective cover 23 is provided outside the second transmission gear 22. The protective cover 23 includes a split upper cover 24 and a lower cover 25. The upper cover 24 and the lower cover 25 are connected by screws to achieve detachable. When performing internal maintenance, only the upper cover 24 needs to be removed. During normal operation, the protective cover 23 can play an external protection role, hiding the second transmission gear 22 inside and improving the use safety.

[0035] Embodiment 2

[0036] A granulator, as Figure 4As shown in the figure, the main difference from Embodiment 1 is that a guide rail 26 is horizontally and fixedly arranged on the machine body 1. The guide rails 26 are symmetrically arranged. At the same time, guide blocks 27 that cooperate with the guide rails 26 are fixed on two symmetric bearing plates 9. The bearing plates 9 are horizontally slidably connected to the guide rails 26 by means of the guide blocks 27. In this way, during the actual disassembly and assembly process, the entire shaper 4 can be horizontally withdrawn to complete the disassembly and assembly, which is more convenient and convenient.

[0037] The above are all the preferred embodiments of this application. The protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
