The application discloses a multi-station rotary product feeding device, which comprises a indexing rotating device, product stations and an adsorbing and transferring device. The indexing rotating device comprises an indexing rotating disc. The product stations are in multiple groups and are symmetrically distributed on the edge of the indexing rotating disc. The adsorbing and transferring device is arranged below the indexing rotating disc. The adsorbing and transferring device can generate adsorbing force on the product received in the product station adjacent to the indexing rotating disc when the indexing rotating disc is stopped. The adsorbing and transferring device moves with the indexing rotating disc to keep the adsorbing force on the product from being interrupted until the product is transferred to the unloading area, and then the adsorbing and transferring device stops adsorbing and moves back to the initial state.

The utility model discloses a main shaft with high stability, which relates to the technical field of main shafts and comprises a main shaft, positioning devices and two belt wheels, and the two belt wheels are fixedly mounted on the main shaft through the positioning devices respectively. The positioning device comprises two rigid sector ring bodies, two elastic damping assemblies and a key block, the two rigid sector ring bodies and the two elastic damping assemblies are spliced into a cylinder structure at intervals in the circumferential direction of the rigid sector ring bodies, and the two elastic damping assemblies are both in pressing fit with the main shaft and the belt wheel; a through groove is formed in one rigid sector ring body in a radial penetrating mode, the main shaft horizontally and fixedly penetrates through the interior of the axis of the positioning device, and the main shaft is in key connection with the belt wheel through a key block. In an assembling state, the arc-shaped cushion block and the round cushion block are both in pressing fit with the main shaft and the belt wheel, so that the friction damping stabilizing effect is achieved, meanwhile, a certain elastic compensation effect is achieved, and linkage and combination stability of the belt wheel and the main shaft are achieved through the key connection effect of the key block.
