The invention discloses a conveying and packaging integrated machine. The conveying and packaging integrated machine comprises a working table, wherein a circulating material conveyer belt is arranged on the working table; a bag making and packaging mechanism is arranged at the discharge end of the circulating material conveyer belt; the bag making and packaging mechanism comprises a material barrel; thin film conveying mechanisms and a vertical sealing mechanism are arranged in sequence in the conveying direction of the thin film on the material barrel; a transverse sealing mechanism is arranged on the lower side of the discharge opening of the material barrel; the thin film conveying mechanisms are arranged on the two opposite sides of the material barrel separately; a fixing ring is arranged in the material barrel; air holes are formed in the fixing ring in the circumferential direction; the air holes communicate with each other through a channel; the conveying and packaging integrated machine further comprises an air pump; the air pump is connected with the air holes through a pipe; the air holes comprise upper air holes and lower air holes; and a sensor is connected with the control mechanism of the air pump. According to the conveying and packaging integrated machine, that materials can easily fall in the openings of bag bodies is ensured while strong collision between the materials and the bag bodies is prevented.
