[0001] The utility model relates to the technical field of packaging machines, in particular to a bag-taking, gripping and bag-opening mechanism for packaging machines. Background Art

[0002] Packaging machines are machines that package products to protect and beautify them. Packaging machines are mainly divided into two aspects: 1. Assembly line overall production packaging, 2. Product peripheral packaging equipment. Packaging bags refer to bags used to package various supplies, making it easy to transport and store goods during production and circulation. They are widely used in daily life and industrial production. Actual figures show that 80% of used plastic bags are eventually transported to garbage dumps like general garbage, and only 7% of plastics are recycled.
