The utility model discloses an automatic
packaging machine capable of realizing
size adjustment through one-key switching, which comprises a
machine table, a main
control system, a plurality of executing mechanisms and a plurality of adjusting mechanisms, the adjusting mechanisms are electrically connected with the main
control system, each adjusting mechanism comprises a driving motor, a transmission mechanism and an adjusting element, and the adjusting elements are connected with the executing mechanisms. According to the utility model, the size parameters of a product are output in the
system, and after calculation is carried out by the
system, the
calculated data are sent to each adjusting mechanism. A driving motor of the adjusting mechanism rotates by a corresponding number of turns according to a
data signal sent by a
system, so that an adjusting element is driven to move by a corresponding distance, and width adjustment is realized. The main
control system adjusts the adjusting mechanisms corresponding to the execution mechanisms at the same time, so that the one-key switching effect is achieved, and tedious operation caused by multiple and repeated input is avoided.
