Description

Technical Field

[0001] This utility model relates to the field of granulators, and in particular to high-precision cutting tools for granulators. Background Technology

[0002] With the continuous development of the processing industry, the demand for refined and efficient manufacturing is increasing, leading to the emergence of granulators as an important industrial equipment. Granulators are mainly used for material processing, transforming large material particles into finer, more uniform particles through physical or chemical methods. On the other hand, cutting tools, as an indispensable part of the granulator, play a crucial role in the entire granulation process. The design and manufacturing level of the cutting tools directly affects the working efficiency and product quality of the granulator. The cutting edges are typically made of cemented carbide or high-strength steel, and through precise edge configuration and a reasonable geometry, effective cutting can be achieved.

[0003] A Chinese patent document CN202120676515.9 discloses a rubber granulator, comprising a granulator body, which is a cylindrical hollow component. An electric heating layer is fixedly installed on the outer wall of the inner cavity of the granulator body. A conveying shaft rotatably connects between the left and right walls of the granulator body, and a spiral blade is fixedly connected to the conveying shaft. The left end of the conveying shaft extends from the left end of the granulator body and is powered by a conveying motor. A feed inlet is fixedly installed at the top left side of the granulator body. An annular output groove extends through the right wall of the granulator body, and three connecting blocks are arrayed within the output groove. This invention, by incorporating a left granulating plate, a right granulating plate, a large granulating hole, and a small granulating hole, can rapidly produce rubber granules of two different particle sizes, reducing limitations in its application.

[0004] However, the above-mentioned patent has certain defects in use. Existing granulators use reamers to rotate and cut the granules in the granulator. However, the hardness and toughness of various materials vary greatly during the cutting process, so reamers of different materials and shapes are needed to adapt to different working conditions.

[0005] To address these issues, a high-precision cutting tool for granulators is proposed. Utility Model Content

[0006] To overcome the shortcomings of existing technologies where different types of reamers are used simultaneously for different materials and require frequent replacement, this utility model provides a high-precision cutting tool for granulators.

[0007] This utility model is achieved using the following technical solution:

[0008] The high-precision cutting tool for the granulator includes a main body and a guide cylinder. The guide cylinder has a guide head at its end and a discharge port at its bottom. A cover is connected to the flange at the end of the guide head. A first motor is located on one side of the main body.

The baffle 71 does not affect the operation of the rotating shaft 41 and they are independent of each other.

[0037] Specifically, a support frame 13 is provided at the bottom of the peripheral wall of the feed cylinder 11.

[0038] In this embodiment, a support frame 13 is provided at the bottom of the peripheral wall of the guide cylinder 11, and the support frame 13 serves to support the guide cylinder 11.

[0039] The principle of this utility model is as follows: Before the entire process is installed, the granulation plate 44 of appropriate size is first fixed to the mounting plate 61 with bolts. Then, the reamer 5 is installed. The mounting block 52 on the outer peripheral wall of the reamer 51 is aligned with the mounting rail 43 on the inner wall of the connector 42 and pushed in. When the mounting block 52 extends along the mounting rail 43 to the bottom of the "L"-shaped mounting rail 43, the reamer 51 is rotated to lock it in place. At this time, the reamer 51 is in contact with the docking plate 44 on the connector 42, and the docking holes 45 correspond one to one. The reamer 5 is fixed with bolts to ensure that it is stable and does not shake. Then, the cover 17 is fixed to the end of the guide head 12. The material is evenly conveyed to the guide cylinder 11 by the second auger 31. The material is pushed to the guide head 12 by the first auger 21 in the guide cylinder 11. It is initially shaped by the granulation plate 6. The third motor 4 drives the rotating shaft 41 and the reamer 5 installed on the connector 42 to cut finely. Finally, it is discharged from the outlet 7.
