a blanking cavity 110 is hollowed in the blanking seat 11;
the shaking platform 12 is arranged at the upper part of the blanking cavity 110, and the lower part of the blanking cavity 110 is communicated to the powder conveying mechanism 2;
the shaking platform 12 is slidably arranged on the blanking seat 11 along the vertical direction, and a buffer spring 14 is arranged between the shaking platform 12 and the blanking seat 11;
the shaking platform 12 is arranged to be of a net structure and is used for filtering powder;
the shaking table 12 is driven by the shaking drive mechanism 13 to shake in the vertical direction.
Specifically, the raw materials of the ceramic product are all powdery, and the raw materials need to be filtered to be packaged and the like, the powder needs to be filtered firstly when the powder is fed, the powder is poured into the powder shaking-off mechanism 1 in the powder feeding device of the embodiment, and after the powder is primarily filtered, the powder falls into the powder conveying mechanism 2 for transportation; the specific filtering work flow is as follows: the powder falls on the shaking platform 12 in the blanking cavity 110 of the blanking seat 11, the shaking platform 12 is a fine mesh structure, and generally the powder with smaller diameter will pass through the mesh of the shaking platform 12 and fall into the powder conveying mechanism 2 through the blanking cavity 110, while the impurities with larger diameter will block the shaking platform 12 and cannot fall off, but a large amount of powder will block the mesh of the shaking platform 12, so that the powder cannot fall off, therefore, the powder feeding device of the embodiment has simple structure, low cost, good filtering effect and high working efficiency, and the shaking driving mechanism 13 is arranged to start the shaking driving mechanism 13 to drive the shaking platform 12 to shake, so that the powder can pass through the mesh and fall off in shaking, thereby completing the primary filtering of the powder, and the buffer spring 14 can effectively protect the shaking platform 12 and the blanking seat 11 in shaking, the service life of the powder feeding device is prolonged.
Further, the bottom end of the shaking platform 12 is at least provided with four positioning posts 121, the inner wall of the blanking seat 11 is correspondingly at least provided with four positioning plates 111, the positioning plates 111 are provided with positioning holes 112, and the positioning posts 121 are limited and arranged in the positioning holes 112.
Specifically, in the present embodiment, the positioning column 121 of the shaking platform 12 is disposed in the positioning hole 112 in a limiting manner, and the aperture of the positioning hole 112 is slightly larger than the diameter of the positioning column 121, so that the shaking platform 12 can shake in the positioning hole 112 in the horizontal direction and shake in the axial direction of the positioning column 121, that is, in the vertical direction, thereby preventing the shaking platform 12 from causing uncontrollable displacement in shaking and improving the stability and safety of movement.
Further, the buffer spring 14 is sleeved outside the positioning post 121, two ends of the buffer spring 14 are respectively connected to the bottom surface of the shaking platform 12 and the upper end surface of the positioning plate 111, and the shaking platform 12 and the positioning plate 111 tend to be away from each other under the elastic force of the buffer spring 14.
Specifically, in this embodiment, the weight of the shaking platform 12 presses on the buffer spring 14, so that the buffer spring 14 is compressed, the elastic force of the buffer spring 14 will lift the shaking platform 12 upwards, the shaking driving mechanism 13 drives the shaking platform 12 to shake, and when the shaking platform 12 shakes in the vertical direction, the buffer spring 14 can provide a buffering effect, so as to avoid the shaking platform 12 colliding with the positioning plate 111, effectively protect the shaking platform 12 and the positioning plate 111, and improve the service life of the powder feeding device.
Further, a limiting ring 15 is disposed at the bottom end of the positioning post 121, and the limiting ring 15 is located below the positioning plate 111. Specifically, in this embodiment, when the shaking platform 12 moves upward along the vertical direction, when the limiting ring 15 touches the bottom surface of the positioning plate 111, the movement of the shaking platform 12 is blocked, so as to prevent the positioning post 121 from separating from the positioning hole 112 during shaking, which results in uncontrollable displacement of the shaking platform 12, and the shaking platform 12 which continuously shakes not only can damage surrounding structures, but also threatens the personal safety of nearby workers, so that the limiting ring 15 can effectively prevent the shaking platform 12 from separating, and the safety of the structure is improved.
Furthermore, a plurality of vibration rods 16 are crosswise arranged on the upper end surface of the shaking platform 12, the shaking driving mechanism 13 is arranged on the shaking platform 12, the shaking driving mechanism 13 is connected with the vibration rods 16, and the shaking driving mechanism 13 transmits the vibration to the shaking platform 12 through the vibration rods 16 when driving.
Specifically, in this embodiment, the vibration rod 16 is disposed on the surface of the shaking platform 12, and the shaking driving mechanism 13 drives the vibration rod 16 to drive the shaking platform 12 to move integrally, so as to improve the transmission efficiency and shaking effect, thereby increasing the falling rate of the powder and improving the working efficiency.
Further, the shaking driving mechanism 13 comprises a mounting seat 131 and a vibration motor 132, wherein the vibration motor 132 is arranged on the upper end surface of the mounting seat 131;
the mounting seat 131 includes a mounting portion 1311 and two transmission pins 1312, the two transmission pins 1312 are respectively disposed at two ends of a lower end surface of the mounting portion 1311, and the two transmission pins 1312 are respectively connected to the two vibration rods 16. Specifically, in this embodiment, after the vibration motor 132 is started, the mounting seat 131 is driven to vibrate, the mounting portion 1311 transmits the vibrating power to the vibration rods 16 through the transmission pins 1312, and then the two vibration rods 16 transmit the vibrating kinetic energy to the other vibration rods 16, and finally the vibration of the whole vibration platform 12 can improve the transmission efficiency of the vibrating kinetic energy, thereby improving the falling rate of the powder and improving the working efficiency.
Further, a magnetic block 17 is disposed above the shake table 12, and the magnetic block 17 has magnetism. In the embodiment, the magnetic block 17 has magnetism, and during the shaking of the shaking platform 12, the magnetic impurities such as iron powder are adsorbed by the magnetic block 17, so that the magnetic impurities such as iron powder in the powder can be removed, and the purity and quality of the powder can be effectively improved.
