Cache feeding device and cache feeding equipment

The invention discloses a cache feeding device and cache feeding equipment, and relates to the technical field of automatic production equipment.The cache feeding device is used for cache and feeding of fins, each fin comprises a fin body and a material collecting needle arranged on the fin body in a penetrating mode, the two ends of each material collecting needle extend out of the two sides, in the second direction, of the fin body, and the two ends of each material collecting needle extend out of the corresponding fin body; the buffering feeding device comprises a buffering feeding mechanism and a feeding mechanism, the buffering feeding mechanism comprises two opposite lifting mechanisms, a containing space for containing a fin body is formed between the two lifting mechanisms, each lifting mechanism is provided with a plurality of material supporting stations at intervals in the lifting direction, the material supporting stations can ascend and descend in the third direction along with the lifting mechanisms, and the second direction intersects with the third direction; the two lifting mechanisms are used for supporting the part, extending out of the fin main body, of the material collecting needle through the material supporting station so as to support the fin; according to the technical scheme, buffering and feeding of the fins can be achieved, and the problem that the fins are prone to being damaged during stacking can be solved.
