This invention provides a metal mask for high-pixel OLEDs and its manufacturing method, relating to the technical field of mask production. The metal mask for high-pixel OLEDs includes a metal mask body, upper etched holes, and lower etched holes. The upper etched holes are formed on one side of the metal mask body, and the lower etched holes are formed on the other side, with the upper and lower etched holes corresponding to each other. Adjacent lower etched holes are interconnected, and the ratio of the distance H2 from the connection point of two lower etched holes to the upper side of the metal mask body to the thickness H1 of the metal mask body is between 1 / 4 and 3 / 4. The manufacturing method of the metal mask for high-pixel OLEDs includes the following steps: steel strip feeding, low-temperature pre-etching to achieve reagent filling; main etching, followed by multiple acid pickling; water washing after acid pickling, and then drying and unloading. This achieves the technical effect of improving the production quality of the metal mask.

The present invention discloses a powder quantitative feeding system and a quantitative feeding control method for asphalt mixing equipment. The powder quantitative feeding system includes a quantitative feeding device and a control device. The quantitative feeding device includes a powder bin, a pulse dust collector installed on the top of the powder bin and a powder feeding mechanism. The pulse dust collector includes a pulse dust collector body and an air supply mechanism. The powder feeding mechanism includes a powder feeding pipeline, a tube bag valve assembly installed on the powder feeding pipeline and a pressure detection assembly. The control method includes: 1. conveying of powder-containing conveying gas; 2. precipitation and filtration of powder; 3. opening of the pulse dust collector; 4. detection of the height of the powder pile; 5. closing of the pulse dust collector.

The utility model relates to the technical field of mud treatment, in particular to a drilling mud treatment system which comprises a diluting unit, a dispersing unit, a stirring unit and a pumping unit, the diluting unit is provided with a diluting cavity, mud to be treated can be firstly introduced into the diluting cavity, the dispersing unit is connected with the diluting unit, and the stirring unit is connected with the pumping unit. The high-pressure water gun can be used for flushing water into the dilution cavity to disperse diluted mud pies and dilute the mud, the stirring unit is connected with the dilution unit, the mud diluted by the dilution unit is introduced into the stirring unit, the stirring unit stirs the mud, and therefore it is guaranteed that the mud dilution uniformity is improved; and the stirred diluted emulsion slurry is conveyed to the stopped salt well dissolving cavity through the pumping unit, so that harmless treatment of the slurry is realized, pollution of the slurry to the ground is avoided, and meanwhile, the treatment cost of the slurry can be effectively reduced.

This invention provides an automated suturing device and robotic platform for oral surgery, relating to the field of oral medical device technology. It includes an operating table with an operation window on its central surface. A rotating assembly is located at the top of the operation window. The rotating assembly includes a toothed ring rotatably mounted around the operation window. A movable frame is fixed to the top of the toothed ring. A needle-threading assembly is located inside the operation window, including a first sliding frame. Compared to existing technologies, the needle-threading assembly and clamping assembly are mounted on the operating table and can be adjusted according to the patient's wound position. After connecting the suture to the suture hook, the suture passes through both sides of the wound under the drive of the needle-threading assembly. The clamping assembly pulls out the suture hook and cuts and knots the suture, facilitating precise positioning and suturing of the oral wound, saving manpower and improving efficiency.

This utility model relates to a multi-segment powder feeding device for heat pipes, comprising a frame, a powder feeding mechanism, and a height adjustment mechanism mounted on the frame for adjusting the height of the powder feeding mechanism. The powder feeding mechanism includes a powder feeding bracket, a long, hollowed-out section mounted on the powder feeding bracket, guide rail assemblies on both sides of the long, hollowed-out section, a movable seat slidably mounted on the guide rail assemblies, and a linear module mounted on the powder feeding bracket for driving the movable seat to move horizontally. At least two powder feeding units are mounted on the movable seat. Each powder feeding unit includes a quantitative powder feeding module, a transfer powder hopper located at the top of the quantitative powder feeding module, and a mixing tank located at the top of the transfer powder hopper. The mixing tanks of multiple powder feeding units are interconnected and driven by a stirring motor. This utility model can achieve the filling of particles of different mesh sizes, has the advantages of simple and compact structure, and the height adjustment mechanism can adjust the height of the powder feeding mechanism, making it suitable for powder injection into copper pipes of different lengths, with strong applicability.
