The invention discloses a preparation method of an InP quantum dot based on silicon-based phosphine salt and the InP quantum dot prepared by the preparation method. The preparation method comprises the following steps: stirring and reacting an indium precursor, silicon-based phosphonium salt MP (TMS) 2 and a selectively added first zinc precursor in a solvent in an inert atmosphere at 150-220 DEG C to obtain a solution containing an InP nanocrystal nucleus, then heating to 240-310 DEG C, adding one or more of a second zinc precursor, a selenium precursor and a sulfur precursor, coating the InP nanocrystal nucleus with a shell layer, and carrying out vacuum drying to obtain the indium-selenium-sulfur-doped InP nanocrystal. The shell layer contains one or more of a zinc element, a selenium element and a sulfur element; m in the silicon-based phosphine salt MP (TMS) 2 is K, Na or Li, and TMS is [-Si (CH3) 3].

The application discloses a tablet candy metal box with a sliding opening and closing structure, which comprises upper and lower box bodies opposite to each other, and an integrally injection-molded injection-molded intermediate part arranged between the upper and lower box bodies. The injection-molded intermediate part is installed at the box opening of the lower box body through interference fit, and the upper box body is installed on the side of the injection-molded intermediate part away from the lower box body through interference fit. After installation, the upper box body can slide transversely relative to the injection-molded intermediate part. The upper and lower box bodies are made of metal, and the injection-molded intermediate part is made of plastic. A through hole is formed in the injection-molded intermediate part for the tablet candy to pass through. Through the "integrally injection-molded intermediate part + metal-plastic material combination + interference fit + detail structure optimization", the three core pain points of the existing sliding candy box, i.e., "complex structure, high cost, difficult assembly, difficult to balance protection and sliding" are solved, and finally the comprehensive advantages of "low-cost production, convenient assembly, high protection and smooth use" are realized.

The invention relates to the technical field of bamboo chip processing, in particular to a bamboo chip sorting machine for bamboo fork and spoon raw materials, which comprises a U-shaped storage bin, and the front end and the rear end of the U-shaped storage bin are fixedly connected with a front cover plate and a rear cover plate respectively; the back of the rear cover plate is fixedly connected with a linkage rod support, the side wall of the linkage rod support is in bolted connection with a grabbing part servo motor, and an output shaft of the grabbing part servo motor drives a rocker to be rotationally connected with the linkage rod support. The rocker is connected with the moving assembly. The moving assembly comprises a base, a sliding block and a connecting rod. The bamboo chip separating device can efficiently and accurately separate bamboo chips with bamboo joints from bamboo chips without bamboo joints. Compared with traditional manual sorting, the sorting efficiency is remarkably improved, and the labor intensity and the misjudgment rate are reduced; compared with general sorting equipment, the equipment is optimally designed for bamboo joint characteristics, is higher in recognition accuracy, compact in structure and lower in cost, and meets the large-scale production requirements of the bamboo product industry.
