[0001] The utility model relates to the technical field of profile packaging, in particular to a horizontal strapping machine with automatic loading and unloading. Background Art

[0002] The aluminum alloy frame of the photovoltaic module has the advantages of high strength and low mass. When the profiles of the aluminum alloy frame of the photovoltaic module are produced on a large scale, in order to facilitate the overall transportation, the aluminum alloy frames will be stacked and packaged using a strapping machine, so as to facilitate the overall transportation.

[0003] For example, Chinese patent CN217673421U discloses a horizontal strapping machine for photovoltaic glass panels, which is provided with a strapping mechanism and a gantry.
