[0040] Embodiment 1

[0041] Please refer to Figure 1 、 Figure 2 This embodiment provides a material selection machine, including a vibration platform 1, a bottom plate 2 and two voice coil motor vibration modules 3 for limiting direction respectively arranged at the front and rear ends between the vibration platform 1 and the bottom plate 2.

[0042] Please refer to Figures 3 to 6The voice coil motor vibration module 3 with a limited direction includes a motor mover 31, a motor stator 32 and an elastic component 33. The motor stator 32 is arranged opposite to the motor mover 31, the motor mover 31 is matched and connected with the motor stator 32, and the elastic component 33 is arranged between the motor mover 31 and the motor stator 32. The elastic component 33 is hollow inside to form a receiving cavity 331 for receiving the motor mover 31 and the motor stator 32. The front end wall of the elastic component 33 is provided with a plurality of first through slots 332 along the vertical direction, and the first and second ends of the first through slots 332 extend to the left and right side walls of the elastic component 33 respectively. The rear end wall of the elastic component 33 is provided with a plurality of second through slots 333 along the vertical direction, and the first and second ends of the second through slots 333 extend to the left and right side walls of the elastic component 33 respectively. The plurality of first through slots 332 and the plurality of second through slots 333 are alternately arranged along the vertical direction. By arranging the first through groove 332 and the second through groove 333 on the elastic component 33, and extending the first and second through grooves 332 and 333 at their ends to the left and right side walls of the elastic component 33, the rigidity of the left and right side walls of the elastic component 33 is significantly enhanced, so that the rigidity of the left and right side walls of the elastic component 33 is greater than the rigidity of the front and rear end walls, so that the vibration energy is more inclined to be transmitted in the front and rear direction, which can effectively reduce the amplitude of the left and right shaking of the vibration platform 1 during operation.

[0043] By adopting the limited direction voice coil motor vibration module 3 of the utility model as a power source, it is not necessary to reserve a large installation space when multiple material selection vibration machines are used side by side to ensure that the machines do not collide with each other, which can reduce the floor space and space cost of the production line; the limited direction voice coil motor vibration module 3 generates vibration through the relative movement of the motor mover 31 and the motor stator 32. Due to the special design of the elastic component 33, not only can the equipment be more flexible, but also the vibration energy can be more effectively converted into the forward and backward vibration of the material on the vibration platform 1, thereby improving the vibration efficiency and enabling the material to achieve the purpose of being arranged in the forward and reverse directions more quickly.

[0044] See also Figures 3 to 5, in one embodiment, the motor mover 31 includes a mover bracket 311, the mover bracket 311 is fixed to the bottom of the vibration platform 1, a magnet sleeve 312 and a magnet assembly 313 are arranged at the bottom of the mover bracket 311, and the magnet assembly 313 is arranged inside the magnet sleeve 312. The motor stator 32 includes a stator bracket 321, the stator bracket 321 is fixed to the top of the bottom plate 2, a coil bobbin 322 is arranged at the top of the stator bracket 321, a coil winding 323 is sleeved outside the coil bobbin 322, the coil bobbin 322 is movably sleeved between the magnet sleeve 312 and the magnet assembly 313 in the vertical direction, and an elastic member 33 is sleeved outside the magnet sleeve 312 and the coil bobbin 322. By adjusting the current and voltage of the coil winding 323, the output force and vibration amplitude of the voice coil motor vibration module 3 in a defined direction can be flexibly controlled, so that the vibration platform 1 can adapt to different types and properties of materials and different production requirements.

[0045] Please refer to Figure 3 , Figure 4 , in one embodiment, a plurality of first heat dissipation holes 3111 communicating with the magnet sleeve 312 are formed in the mover bracket 311. By forming a plurality of first heat dissipation holes 3111 communicating with the magnet sleeve 312 in the mover bracket 311, the heat generated by the coil winding 323 inside the voice coil motor vibration module 3 in a defined direction can be effectively dissipated, preventing heat from accumulating inside the magnet sleeve 312, thereby reducing the operating temperature of the motor; due to the effective dissipation of internal heat, the thermal influence on the elastic member 33 can be reduced, avoiding the problem of attenuation of the bounce force of the elastic member 33 caused by long-term high-load operation, thereby maintaining the stability and long service life of the motor.

[0046] Please refer to Figure 3 , Figure 5 , further, in one embodiment, a plurality of second heat dissipation holes 3211 communicating with the coil bobbin 322 are formed in the stator bracket 321. Since the second heat dissipation holes 3211 communicate with the coil bobbin 322, the heat generated by the coil winding 323 can not only be dissipated from the first heat dissipation holes 3111 to the external environment, but also be dissipated from inside the coil bobbin 322 to the external environment through the second heat dissipation holes 3211. By increasing the heat dissipation surface area, the heat dissipation speed is thus accelerated.

[0047] Please refer to Figure 3 , Figure 4, in one embodiment, a heat dissipation groove 3112 is formed at the top of the mover bracket 311. One end of the heat dissipation groove 3112 extends to a certain edge of the mover bracket 311, and the first heat dissipation hole 3111 is formed at the bottom of the heat dissipation groove 3112. The setting of the heat dissipation groove 3112 effectively avoids the problem that the vibration platform 1 may block the first heat dissipation hole 3111 when the mover bracket 311 is connected to the vibration platform 1, ensures the unobstructedness of the first heat dissipation hole 3111, and guarantees that the heat dissipation effect is not affected. In the case where the top of the mover bracket 311 is in contact with the vibration platform 1, the heat inside the magnet sleeve 312 can be conducted along the channel of the heat dissipation groove 3112 after passing through the first heat dissipation hole 3111 and dissipated into the external environment at the end of the channel.

[0048] Of course, in another embodiment, a coil bobbin 322 may also be provided at the bottom of the mover bracket 311, and a coil winding 323 is sleeved outside the coil bobbin 322. A magnet sleeve 312 and a magnet assembly 313 may also be provided at the top of the stator bracket 321. The magnet assembly 313 is arranged inside the magnet sleeve 312. The coil bobbin 322 is movably sleeved between the magnet sleeve 312 and the magnet assembly 313 in the vertical direction, and an elastic member 33 is sleeved outside the magnet sleeve 312 and the coil bobbin 322. Correspondingly, a plurality of first heat dissipation holes 3111 communicating with the magnet sleeve 312 are formed in the stator bracket 321, and a plurality of second heat dissipation holes 3211 communicating with the coil bobbin 322 are formed in the mover bracket 311.

[0049] Please refer to Figure 6 , in one embodiment, the elastic member 33 is of a hollow square column structure. Of course, in other embodiments, the elastic member 33 may also be a hollow rectangular structure, a hollow cylindrical structure, a hollow elliptical cylindrical structure and other hollow elastic structures, and the present utility model does not limit this.

[0050] Please refer to Figure 7, in another embodiment, the motor mover 31 includes a mover bracket 311, the mover bracket 311 is fixed to the bottom of the vibration platform 1, and a magnet assembly 313 is provided at the bottom of the mover bracket 311. The motor stator 32 includes a stator bracket 321, the stator bracket 321 is fixed to the top of the bottom plate 2, a coil bobbin 322 is provided at the top of the stator bracket 321, a coil winding 323 is sleeved outside the coil bobbin 322, the coil bobbin 322 is movably sleeved outside the magnet assembly 313 in the vertical direction, and an elastic member 33 is provided between the mover bracket 311 and the stator bracket 321 and is sleeved outside the coil bobbin 322. In this embodiment, by canceling the steel sleeve sleeved outside the coil winding 323, the heat generated by the coil winding 323 can be dissipated in time, avoiding the accumulation of heat inside the steel sleeve, thereby reducing the operating temperature of the motor; due to the effective dissipation of internal heat, the thermal influence on the elastic member 33 can be reduced, avoiding the problem of thermal attenuation of the bounce force of the elastic member 33 caused by long-term high-load operation, thereby maintaining the stability and long service life of the motor.
