The variable-distance suction component transfers the product in the temporary rotating platform 4 to the loading transition structure 3. The entire loading process realizes uninterrupted automatic circulation, thereby improving the loading efficiency. The tray 63 in the tray adsorption structure 6 cooperates with the L-shaped card plate 64 and the tray cylinder 66 to realize the accurate positioning and transfer of the blister tray 8. The rotating shaft 78 in the variable-distance suction component 71 drives the fixed rod 79 to move along the through hole 73 to realize the adjustment of the product adsorption spacing, and accurately transfers the product in the temporary tray 42 to the blister tray 8 of the corresponding size, thereby enhancing the applicability of positioning products in different blister trays 8.
