Structure Design and Characteristic Test of Transfer Device for Small Special-shaped Fragile Solid Materials

The work aims to develop a transfer device to meet the addition requirements of small special-shaped fragile solid materials. Transient dynamics simulation and analysis method was adopted to carry out transient dynamics simulation and analysis on small solid materials subject to impact and collision with ANSYS WorkBench software and to study the maximum rotational speed that the materials could withstand. The reliability and stability of the device were verified by setting up a platform for the physical transfer test, and the optimal rotational speed was obtained to improve the production efficiency. According to the simulation results, the maximum rotational speed that the materials could withstand was 1 200 r/min, otherwise the materials failed. According to the test of transferring materials, the structure design of the device is reasonable, which can meet the working requirements of transferring materials in the continuous high-speed state, and achieve the maximum quantity of intact materials and the highest production efficiency at 600 r/min.
