The invention discloses a chain material collecting mechanism, and belongs to the field of packaging machines. The problem that pole plates are located inaccurately due to large gaps of chain plates is solved. The chain material collecting mechanism comprises a chain, the chain comprises a plurality of chain links, the two sides of each chain link are each provided with a chain plate, the chain plates on the two sides of each chain link are fixedly connected with the corresponding chain link, connecting holes are formed in the chain plates, a plurality of aluminum plates are arranged on the chain, connecting holes are formed in the aluminum plates, the aluminum plates and the chain plates are fixedly connected through bolts penetrating through the connecting holes, and through grooves are formed in the aluminum plates. Push rods are arranged on the aluminum plates, and are perpendicular to the surfaces of the aluminum plates. Gaps between the chain links of the chain are small, the positions of the aluminum plates are accurate, and therefore the pole plates are located accurately.
