The magnetic structure 310 includes a housing 40, a first magnetic rotor 310, a second magnetic rotor 320, and an iron core 330, the housing 40 defines a mounting cavity 40a therein, the first magnetic rotor 310 is connected to the first arbor 10 to rotate synchronously with the first arbor 10, the second magnetic rotor 320 is located at one axial side of the first magnetic rotor 310, the second magnetic rotor 320 is connected to the second arbor 20 to rotate synchronously with the second arbor 20, and the iron core 330 is disposed between the first magnetic rotor 310 and the second magnetic rotor 320 such that the first magnetic rotor 310 and the second magnetic rotor 320 rotate in opposite directions. The first magnetic rotor 310, the second magnetic rotor 320 and the iron core 330 are all arranged in the installation cavity 40 a; an air inlet hole 411 is formed in the bottom wall of the shell 40, an air outlet hole 414 is formed in the side wall of the shell 40, an air flow channel 331 is formed in the iron core 330, air enters the air flow channel 331 from the air inlet hole 411, and air exits the air flow channel 331 from the air outlet hole 414.
It can be understood that, since the bottom wall of the housing 40 is provided with the air inlet holes 411 and the side wall is provided with the air outlet holes 414, and the iron core 330 is provided with the air flow channel 331, when the knife assembly 1 works, the air flow enters the installation cavity 40a from the air inlet holes 411 at the bottom of the housing 40, passes through the air flow channel 331 and finally leaves the installation cavity 40a from the air outlet holes 414. Therefore, airflow circulates in the installation cavity 40a in the engineering process of the knife assembly 1 all the time, and the airflow can flow through the airflow channel 331 on the iron core 330, so that the iron core 330, the first magnetic rotor 310 and the second magnetic rotor 320 can be cooled in the rotating process of the knife assembly 1, the heat generation of the knife assembly 1 is reduced, the loss of parts of the knife assembly 1 is reduced, and the service life of the knife assembly 1 is prolonged.
According to the knife assembly 1 of the embodiment of the invention, the air inlet 411 is arranged on the bottom wall of the shell 40, the air outlet 414 is arranged on the side wall of the shell, and the air flow channel 331 is arranged on the iron core 330, so that air flow always circulates in the installation cavity 40a in the engineering process of the knife assembly 1, and the air flow can flow through the air flow channel 331 on the iron core 330, and thus the temperature reduction of the iron core 330, the first magnetic rotor 310 and the second magnetic rotor 320 in the rotation process of the knife assembly 1 can be realized, the heat generation of the knife assembly 1 is reduced, the loss of parts of the knife assembly 1 is reduced, and the service life of the knife assembly 1 is prolonged.
It should be noted that, in the present invention, the first cutter shaft 10 rotates synchronously with the first magnetic rotor 310, and the second cutter shaft 20 rotates synchronously with the second magnetic rotor 320. Therefore, in actual work, only one of the first cutter shaft 10, the first magnetic rotor 310, the second cutter shaft 20 and the second magnetic rotor 320 is connected with the motor, and the first cutter shaft 10 and the second cutter shaft 20 can rotate in opposite directions, and the power input mode of the cutter assembly 1 is not specifically limited.
In some embodiments, as shown in FIG. 8, the core 330 has a central bore 332 for receiving the first cutter arbor 10, and the airflow passage 331 includes a plurality of spaced apart ventilation holes 3311 surrounding the central bore 332. It will be appreciated that the air inlet holes 411 are provided in the bottom wall of the housing 40, that is, the core 330 is disposed above the air inlet holes. The air flow channel 331 on the iron core 330 is provided with a plurality of ventilation holes 3311 distributed at intervals around the central hole 332, which is beneficial for the air flow entering the mounting cavity 40a from the air inlet holes 411 to uniformly flow through the air flow channel 331, and the heat dissipation effect of the iron core 330 is better improved. It should be noted that the main function of the ventilation holes 3311 is to allow air to pass through, and therefore, the shape and size of the ventilation holes 3311 are not specifically limited, that is, the ventilation holes 3311 may be formed as holes of any shape and size according to actual needs.

It is to be understood that the air flow path 331 further includes a flow path groove 3312 connected to the ventilating holes 3311 and formed to the surface of the core 330, so that the core 330 is cooled by the air flowing through the ventilating holes 3311 and the core 330 is cooled by the air flowing through the flow path groove 3312 when the air flows through the air flow path 331. That is, the channel slots 3312 are formed in the surface of the core 330 to prevent the core 330 from overheating. It should be noted that the connection of the two ends of the channel slot 3312 to the same or different vent holes 3311 does not affect the cooling effect of the air flow in the air flow channel 331 on the core 330. Therefore, in the embodiment of the present invention, both ends of the flow path grooves 3312 may be connected to the same vent holes 3311 or different vent holes 3311. In addition, the specific shape of the runner groove 3312 may be selected according to the actual shape and size of the core 330. The shape and size of the flow channel 3312 are not limited thereto.
In some more specific embodiments, as shown in fig. 8, the core 330 is provided with flow channel grooves 3312 at radially outer sides of each of the ventilation holes 3311, and auxiliary ventilation holes 3313 are provided between each two adjacent flow channel grooves 3312.

Of course, the above description is only illustrative of the vent holes 3311, the flow channel grooves 3312, and the auxiliary vent holes 3313, and is not particularly limited, and the size and shape of the vent holes 3311, the flow channel grooves 3312, and the auxiliary vent holes 3313 may be arbitrarily adjusted according to actual needs.
In some embodiments, as shown in fig. 4 to 5, the first magnetic rotor 310 includes a first magnetic sleeve 311, a first magnetic shoe 312 and a first cover plate 313, the first magnetic sleeve 311 has a first shaft hole 3111 matching with the first shaft 10, a first mounting groove 3112 surrounding the first shaft hole 3111 is provided on the first magnetic sleeve 311, the first magnetic shoe 312 is disposed in the first mounting groove 3112, the first cover plate 313 covers the first magnetic sleeve 311, and the first magnetic shoe 312 is disposed between the first magnetic sleeve 311 and the first cover plate 313. Thereby, a stable mounting of the first magnetic rotor 310 to the first cutter shaft 10 can be ensured, so that the first magnetic rotor 310 can stably rotate the first cutter shaft 10.

In some specific embodiments, as shown in fig. 5, the first magnetic sleeve 311 is provided with a plurality of first blades 3113 arranged around the first shaft hole 3111, and the first blades 3113 are located radially inside the first mounting groove 3112. It will be appreciated that when the knife assembly 1 is in operation, the first magnetic rotor 310 may rotate and the first magnetic sleeve 311 of the first magnetic rotor 310 is provided with a plurality of first vanes 3113. Therefore, when the first magnetic rotor 310 rotates, the plurality of first vanes 3113 also rotate, which accelerates the flow of the air in the installation cavity 40a, thereby better achieving the cooling of the core 330 and the first magnetic rotor 310. Here, it should be noted that the plurality of first blades 3113 may be integrally formed with the first magnetic sleeve 311, or may be formed as a separate wind wheel installed around the first shaft hole 3111, and the specific shape and forming manner of the first blades 3113 are not limited herein.
In some embodiments, as shown in fig. 6-7, the second magnetic rotor 320 includes a second magnetic sleeve 321, a second magnetic shoe 322, and a second cover plate 323.

Therefore, the second magnetic rotor 320 and the second knife shaft 20 can be stably installed, so that the second magnetic rotor 320 can stably drive the second knife shaft 20 to rotate. Of course, in other embodiments of the present invention, the second magnetic rotor 320 is directly formed by splicing a plurality of second magnetic tiles 322.
In some specific embodiments, as shown in fig. 7, a plurality of second blades 3213 are disposed on the second magnetic shoe 322 around the second shaft hole 3211, and the second blades 3213 are located radially inward of the second mounting groove 3212. It is understood that when the knife assembly 1 is in operation, the second magnetic rotor 320 can rotate, and the second magnetic sleeve 321 of the second magnetic rotor 320 is provided with a plurality of second blades 3213. Therefore, when the second magnetic rotor 320 rotates, the plurality of second vanes 3213 also rotate, which accelerates the flow of the air in the installation cavity 40a, thereby better cooling the core 330 and the second magnetic rotor 320. Here, it should be noted that the plurality of second blades 3213 may be integrally formed with the second magnetic sleeve 321, or may be formed as a separate wind wheel installed around the second shaft hole 3211, and the specific shape and forming manner of the second blades 3213 are not limited herein.
In some embodiments, as shown in fig. 9, the bottom wall of the housing 40 is provided with a mounting hole 412 for engaging with the first blade shaft 10, the air inlet holes 411 are a plurality of holes surrounding the mounting hole 412, and each air inlet hole 411 is a long hole extending radially along the bottom wall of the housing 40. It can be understood that the air inlet holes 411 are formed as elongated holes extending in the radial direction to ensure the flow rate of the air entering the installation cavity 40a, thereby ensuring the cooling effect of the iron core 330, the first magnetic rotor 310 and the second magnetic rotor 320, and the air inlet holes 411 are formed as a plurality of holes surrounding the assembly holes 412 to better ensure the uniformity of the inlet air flow, thereby preventing the local overheating phenomenon in the installation cavity 40a caused by uneven inlet air. Of course, in other embodiments of the present invention, the assembly holes 412 may be formed in any other shape or in any other distribution manner, and the above description is only illustrative of the assembly holes 412 and is not particularly limited.
In some embodiments, as shown in fig. 1-2, the housing 40 includes a bottom case 410 and a cover case 420, the cover case 420 covers the top of the bottom case 410 to define the installation cavity 40a, the bottom case 410 is provided with a plurality of upper extension blocks 413 spaced apart along a circumferential edge, the cover case 420 is provided with a plurality of lower extension blocks 423 spaced apart along a circumferential edge, the cover case 420 is connected to the bottom case 410 by the plurality of lower extension blocks 423, each of the lower extension blocks 423 is provided with an upper extension block 413 corresponding to a radially inner side or a radially outer side, and an air outlet 414 is defined between two adjacent lower extension blocks 423.

The provision of the outlet 414 in the side wall of the cover 420 thus ensures that no liquid from the crushing chamber can enter the mounting chamber 40 a. The air outlet 414 is defined by the upper extension block 413 on the bottom shell 410 and the lower extension block 420, and the sealing performance of the installation cavity 40a in the overlapping area of the upper extension block 413 and the lower extension block 423 is ensured.
