Automatic packaging bag production device and method

An automatic packaging bag production device, comprising:

• an easy-tear line forming mechanism, comprising a first passage, and configured to form an easy-tear line on a belt-shaped material passing through the first passage;
• a sealing and cutting mechanism, comprising a second base plate, and a cutting assembly and a sealing assembly arranged on the second base plate, wherein the cutting assembly comprises an upper cutter and a lower cutter;
• a second passage is formed between the upper cutter and the lower cutter, and the upper cutter and the lower cutter are driven by a third driving element to move close to or away from each other;
• the sealing assembly comprises an upper sealer and a lower sealer;
• and a third passage is formed between the upper sealer and the lower sealer, and the upper sealer and the lower sealer are driven by a fourth driving element to move close to or away from each other;
• a tray, wherein the first passage, the second passage, the third passage, and the tray are sequentially arranged;
• and
• a traction mechanism, configured to pull the belt-shaped material for a sequence of operations as follows:
• in the first passage, the easy-tear line forming mechanism forms the easy-tear line on the belt-shaped material;
• in the second passage, the upper cutter and the lower cutter move close to each other to cut a packaging bag, such that the packaging bag falls onto the tray;
• and in the third passage, the upper sealer and the lower sealer move close to each other to heat-seal a tail end of the packaging bag.
