Extending machine with limiting function for aluminum honeycomb panel

The utility model discloses an aluminum honeycomb panel extension machine with a limiting function, which comprises a host end, heat dissipation holes and an extension mechanism, heat dissipation holes are formed in the upper end of the host end and can maintain the temperature balance of the whole machine, and an extension mechanism is arranged below the heat dissipation holes; according to the utility model, after the extension mechanism is improved, in the process that the aluminum honeycomb panels with different sizes and thicknesses enter from the feeding end to be correspondingly contacted with the contact shaft, the aluminum honeycomb panels can push the stretching shaft of the rotator according to different thicknesses of the aluminum honeycomb panels, so that the gap formed by the contact shaft can be quickly adjusted; and therefore, the aluminum honeycomb plates with different thicknesses can be conveniently and quickly extruded and extended, and the phenomenon that the aluminum honeycomb plates wit
