The invention discloses an adsorption type multi-material additive material powder laying system and method based on a micropore array. The powder laying system comprises a forming chamber, a powder supply device, a powder laying device and a powder scraping device. A forming platform is arranged in the forming chamber; the powder laying device comprises a mesh screen, a vacuum pump and a powder falling mechanism, powder particles can be evenly adsorbed to the periphery of the mesh screen through cooperation of the mesh screen and the vacuum pump, the powder particles cannot penetrate through micropores to enter the mesh screen, the micropores cannot be completely covered, airflow can still pass through gaps between the micropores and the powder particles, and the powder falling mechanism is more uniform in powder falling. When the powder is laid, the powder particles on the periphery of the mesh screen are laid on the forming platform through the powder falling mechanism, so that more powder particles can be continuously adsorbed, part of the powder particles are scraped off through the powder scraping device, the thickness of the powder adsorbed on the periphery of the mesh screen is accurately controlled, and during powder laying, the powder particles on the periphery of the mesh screen are laid on the forming platform through the powder falling mechanism, so that various powder materials can be uniformly and accurately laid in corresponding areas; the problem that different kinds of powder are accurately laid in one layer is solved, and XY plane multi-material additive manufacturing is achieved.

The utility model relates to a kind of negative pressure weighing chamber for ice bor scattering, belong to negative pressure weighing chamber technical field, including box, the inner top wall of the box is equipped with the weighing chamber body that can provide stable space to ice bor scattering and weigh, the inner left wall of the box is equipped with the air flow component that is powered for gas flow, the top of the weighing chamber body is equipped with the adjustment component that can control the size of air intake speed, the inner bottom wall of the box and below the weighing chamber body is equipped with the first filter component that carries out primary filtration to air, the inner left wall of the box is equipped with the secondary filter component that carries out further filtration to air.The negative pressure weighing chamber for ice bor scattering, by the cooperation of first electric fan, secondary electric fan and adjustment component, can guarantee the uniformity of pressure difference while improving air outlet, to better meet the actual needs of ice bor scattering, improve weighing stability, by the cooperation of first filter component and secondary filter component, can effectively filter and sterilize air.

The invention relates to a multilayer dye box and a dyeing device for supercritical waterless dyeing, the dye box comprises a dye box body and a dye box inner cylinder, the dye box inner cylinder is arranged in the dye box body, the dye box inner cylinder comprises a plurality of cylinder sections, the cylinder sections are mutually matched in structure and can be detachably connected, and the dye box inner cylinder is arranged in the dye box body. An independent dye containing space is arranged in each shell ring, a circulation bottom plate is arranged on each shell ring and used for dividing the adjacent dye containing spaces, circulation holes used for circulation of supercritical gas are formed in the circulation bottom plates, a gas inlet is formed in the dye box body, one end of the gas inlet is connected with the supercritical gas, and the other end of the gas inlet is connected with the supercritical gas. And the other end of the cylinder section is positioned in the dye box inner cylinder and is used for guiding dye supercritical gas into the cylinder section. The problem that a large amount of undissolved dye is accumulated in the dyeing box and blocks the filter screen after carbonization is effectively avoided, and the problem of low-efficiency dyeing caused by dye accumulation is solved.
