Article adsorption turnover mechanism

The utility model relates to an article adsorption turnover mechanism. A driving device drives a crawler belt to convey articles. The adsorption turnover device comprises a double-shaft stepping motor, an adsorption barrel, a vortex vacuum pump and an induction block, the adsorption barrel is installed on an inner rotating shaft of the double-shaft stepping motor, the induction block is installed on an outer rotating shaft of the double-shaft stepping motor, and the adsorption barrel is provided with an adsorption opening with adsorption force provided by the vortex vacuum pump; the feeding side of the rack is provided with a photoelectric sensor for sensing feeding objects on the caterpillar band, the discharging side of the rack is provided with a proximity sensor, and when the sensing block is close to the proximity sensor, a signal is generated to enable the double-shaft stepping motor to reset to zero; the limiting device is provided with pipe straightening frames arranged on the two sides in the article
