Full-automatic stretch film packaging machine

The utility model relates to the technical field of packaging equipment, in particular to a full-automatic stretch film packaging machine which is characterized in that a material roller is quickly mounted on a fixing frame through a clamping mechanism, and a packaging film is pulled out from the material roller and falls on a conveying mechanism through a gap between a driving wheel and a driven wheel; then the first motor drives the driving wheel to rotate to continuously pull out the packaging film, finally the first air cylinder is started to press the hot-pressing head downwards to complete packaging, in the downwards-pressing process of the hot-pressing head, the buffer plate firstly makes contact with the conveying mechanism, the packaging film is pressed under the action of the spring, a certain buffer effect is achieved, and impact of the hot-pressing head is relieved; comprising a base, a bottom column, a conveying mechanism and a cutting mechanism; the device further comprises a fixing frame, a mat
