[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-4 An underwater colloidal high molecular polymer granulation and cutting device comprises a driving motor 1, and the shaft end of the driving motor 1 is fixedly connected to a pelletizing mechanism 2 through a coupling 3.

[0025] The pelletizing mechanism 2 includes a shaft tube 201, an irregular through hole penetrating to both ends is opened at the center of the shaft tube 201, and the two ends of the through hole are respectively fixedly connected with a strong magnetic electromagnet 2011 and a bearing 2012, wherein the strong magnetic electromagnet 2011 is fixed at one end close to the drive motor 1, and the magnetic end points to the direction of the bearing 2012, the bearing 2012 is fixedly connected to one end close to the pelletizing mechanism 2, and slots are symmetrically opened on the inner wall, the interior of the shaft tube 201 is movably connected to the shaft sleeve 2021 through the bearing 2012, one end of the shaft sleeve 2021 is fixed with a limited convex plate corresponding to the slot of the bearing 212, and the shaft sleeve 2021 is fixed with a limited convex plate. A magnet column 2022 is fixedly connected to the inside at one end close to the strong magnetic electromagnet 2011, a rotation groove is opened inside the sleeve 2021 at a position relative to the magnet column 2022, and a shaft body 2023 is rotatably connected inside the rotation groove, a spine 2024 is fixedly connected to the upper side of the shaft body 2023, the structure of the spine 2024 is similar to the shape of the spine and ribs, and a circular plate is fixed to each support rod end, and a buffer spring 2025 is set on the end surface of the circular plate. The buffer spring 2025 is set in an arc-shaped channel opened inside the sleeve 2021, and one end of the shaft body 2023 passes through the sleeve 2021 and is fixedly connected to the cutter 202.

[0026] During the long-term pelletizing process, if the blade on the cutter 202 moves, the blade will hit the surface of the extrusion die under the centrifugal action driven by the drive motor 1, and at the moment of impact, the interaction force between the blade and the extrusion die will cause the cutter 202 to stop suddenly, and the sudden stop of the cutter 202 will not affect the rotation of the drive motor 1, the shaft tube 201 and the shaft sleeve 2021. As the drive motor 1 drives the shaft tube 201 and the shaft sleeve 2021 to continue to rotate, the shaft body 2023 connected to the cutter 202 will further deflect in the reverse direction and compress the buffer spring 2025. If the contact friction between the cutter 202 and the extrusion die is small, at this time, as the strong magnetic electromagnet 211 magnetically attracts and drags the magnet column 2022 , the cutter 202 will be separated from the extrusion die, and the staff needs to perform emergency braking and maintenance of the equipment at this time; if the friction between the cutter 202 and the extrusion die is large, the magnet column 2022 will be separated from the magnetic attraction of the strong magnetic electromagnet 2011, and then the cutter 202 will enter a stagnant state to avoid serious damage to the cutter 202, and then the staff needs to perform emergency braking and maintenance of the cutter 202; during maintenance, the current direction of the strong magnetic electromagnet 2011 can be changed to change the magnetic pole of the strong magnetic electromagnet 2011, and then the strong magnetic electromagnet 2011 will repel the magnet column 2022, so that the sleeve 2021 drives the cutter 202 to slide outward along the bearing 2012, and then the cutter 202 can be removed for maintenance.

[0027] In summary, by configuring the shaft tube 201, the strong magnetic electromagnet 2011, the bearing 2012, the shaft sleeve 2021, the magnet column 2022, the shaft body 2023, the spine 2024 and the buffer spring 2025, the characteristic of the flexible connection can be utilized, so that when the cutter 202 collides, it can not only try to separate the cutter 202 from the extrusion die in a flexible traction manner, so that the cutter 202 and the extrusion die are transformed into a face-to-face sliding relationship, but also the cutter 202 can be separated from the drive motor when strong friction occurs. 1, stops running, thereby preventing the cutter 202 from being seriously damaged when a collision occurs, and greatly reducing the maintenance cost; through the arrangement of the shaft tube 201, the strong magnetic electromagnet 2011, the shaft sleeve 2021 and the magnet column 2022, the characteristic of the strong magnetic electromagnet 2011 that the magnetic poles can be freely changed can be utilized, and according to the principle that like poles repel each other and opposite poles attract each other, the cutter 202 can be quickly adsorbed, positioned and discharged from the inside of the shaft tube 201, thereby greatly improving the convenience of maintenance of the cutter 202.

[0028] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0029] Working principle: When working, the driving motor 1 will drive the shaft tube 201 and the cutter 202 to rotate from low speed to high speed under the adsorption effect of the strong magnetic electromagnet 2011 on the magnet column 2022. In the initial stage of rotation, the cutter 202 will take the shaft body 2023 as the axis and perform a certain rotation deflection in the reverse direction under the action of inertia, and compress the buffer spring 2025 on the side to a certain extent during the deflection process until it rotates to a stable state, and then the cutter 202 will granulate and pelletize the extruded material, and the pelletized material will be cooled and taken away by the input circulating water flow; during the long-term pelletizing process, if the blade on the cutter 202 moves, the blade will hit the surface of the extrusion die under the centrifugal action driven by the driving motor 1, and at the moment of impact, the interaction force between the blade and the extrusion die will cause the cutter 202 to stop suddenly, and the cutter 202 that stops suddenly will not affect the rotation of the driving motor 1, the shaft tube 201 and the sleeve 20 21 continues to rotate, the shaft 2023 connected to the cutter 202 will further rotate in the reverse direction and compress the buffer spring 2025. If the contact friction between the cutter 202 and the extrusion die is small, the cutter 202 will be separated from the extrusion die as the strong magnetic electromagnet 2011 magnetically pulls the magnet column 2022. At this time, the staff needs to perform emergency braking and maintenance of the equipment; if the friction between the cutter 202 and the extrusion die is large, the magnet column 2022 will be separated from the strong magnetic electromagnet 2011. The cutter 202 will enter a stagnant state due to the magnetic attraction to avoid serious damage to the cutter 202. The staff will then need to perform emergency braking of the equipment and overhaul the cutter 202. During the overhaul, the current direction of the strong magnetic electromagnet 2011 can be changed to change the magnetic pole of the strong magnetic electromagnet 2011. The strong magnetic electromagnet 2011 will then repel the magnet column 2022, causing the sleeve 2021 to drive the cutter 202 to slide outward along the bearing 2012. The cutter 202 can then be removed for overhaul.
