[0026] See also Figures 1 to 3The present invention provides a powder feeding box 100, which is applied to the field of powder forming technology. In the present embodiment, the powder feeding box 100 transports ceramic powder, but in the actual embodiment, it can also be other powdered materials, and the present invention does not limit it. The powder feeding box 100 includes a cavity 30 with a plurality of through holes 30A arranged at intervals, a support frame 10 arranged around the outside of the cavity 30, a first telescopic mechanism 40 fixed to the support frame 10 and connected to the cavity 30 for driving the cavity 30 to move up and down, a cover plate 50 covering the top of the cavity 30, and a second telescopic mechanism driving the cover plate 50 to move up and down. The powder feeding box 100 is a fidelity powder feeding box. After the ceramic powder is laid out in a pattern by a laying device, the powder feeding box 100 is used to move the ceramic powder, which can ensure that the pattern does not change during the movement and maintain the original pattern to the greatest extent. Specifically, when the powder feeding box 100 moves along the guide rail to the loading position, the cavity 30 moves downward and abuts against the support plate carrying the powder, and the powder enters the through hole 30A of the cavity 30. After the material is loaded, that is, the pattern is arranged, the cover plate 50 moves downward and abuts against the cavity 30 under the drive of the second telescopic mechanism, and seals the powder in the through hole 30A. Then the power mechanism drives the support frame 10 connected thereto to continue to move along the guide rail, and the powder in the cavity 30 moves horizontally on the support plate with the powder feeding box 100. When it moves to the pressing position, the cover plate 50 moves upward under the drive of the second telescopic mechanism. After moving to the extreme position, the cavity 30 also moves upward under the drive of the first telescopic mechanism 40, so that the powder leaves the through hole 30A of the cavity 30, and the ceramic powder with the pattern is delivered to the pressing position in a fidelity manner.

[0027] Preferably, the support frame 10 includes an outer frame 11 connected to the guide rail and an inner frame 13 accommodated in the outer frame 11 and capable of moving up and down relative to the outer frame 11.

In this embodiment, the powder feeding box 100 also includes a third telescopic mechanism 60 for driving the inner frame 13 to move up and down, and the third telescopic mechanism 60 is fixed to the inner wall of the outer frame 11 and connected to the inner frame 13. When the powder feeding box 100 moves along the guide rail to the loading position, the inner frame 13, the cavity 30 and the cover plate 50 move downward in sequence, and when the powder feeding box 100 moves along the guide rail to the pressing position, the cover plate 50, the cavity 30 and the inner frame 13 move upward in sequence.

[0028] In this embodiment, the inner frame 13 includes an inner frame 131 with a hollow structure and a first limiting plate 133 extending from a surface of the inner frame 131 close to the cover plate 50 into the hollow structure, and a hole is formed in the first limiting plate 133 .

The first partition 335 is sandwiched between the horizontal beam 331 and the frame 31 or between adjacent horizontal beams 331; the second partition 337 is sandwiched between the longitudinal beam 333 and the frame 31 or between adjacent longitudinal beams 333. The plurality of horizontal beams 331 are cross-arranged with the plurality of longitudinal beams 333 and the plurality of second partitions 337; the plurality of second partitions 335 are also cross-arranged with the plurality of longitudinal beams 333 and the plurality of second partitions 337; that is, the horizontal beams 331, the first partitions 335, the longitudinal beams 333 and the second partitions 337 are cross-arranged with each other to divide the frame 31 into a plurality of evenly arranged small grids, that is, a plurality of spaced through holes 30A. The cross beam 331 and the longitudinal beam 333 are thicker than the first partition plate 335 and the second partition plate 337, so as to ensure the load-bearing capacity of the grid frame 33 when the cavity 30 is pressed downward, and prevent the grid from being deformed.

[0031] Preferably, the surface area of ​​the cross beam 331 and the longitudinal beam 333 away from the cover plate 50 is smaller than the surface area close to the cover plate 50, so that the design can reduce the impact on the pattern. Specifically, in this embodiment, the cross beam 331 includes a first portion away from the cover plate 50 and a second portion connected to the first portion, the surface area of ​​the first portion away from the cover plate 50 is equal to the surface area close to the cover plate 50, and the thickness of the second portion gradually decreases from the surface away from the cover plate 50 to the surface close to the cover plate 50.

The second surface 339 is composed of the surface of the cross beam 331, the longitudinal beam 333, the first partition plate 335 and the second partition plate 337 away from the cover plate 50.

[0033] During the movement of the powder feeding box 100, the frame 31 abuts against the support plate, and the grid frame 33 is spaced apart from the support plate. In order to ensure the integrity of the powder and prevent it from leaking out from the edge of the frame 31, preferably, the cavity 30 further comprises a rubber strip, which is attached to the surface of the frame 31 away from the cover plate 50, i.e., the first surface 311, and during the movement of the powder feeding box 100, the rubber strip abuts against the support plate.

When the powder feeding box 100 moves to the loading position, the inner frame 13 moves downward, and when the first limit plate 133 abuts against the second limit plate 35, that is, it moves to the downward limit position, and then the cavity 30 moves downward; when the powder feeding box 100 moves to the pressing position, the cavity 30 moves upward, and when the second limit plate 35 abuts against the first limit plate 133, that is, when the cavity 30 moves to the upward limit position, then the inner frame 13 moves upward.
