The invention relates to the technical field of protection-layer-free heat-sensitive material packaging, in particular to a protection-layer-free heat-sensitive material prolonged storage mechanical packaging device and method.The protection-layer-free heat-sensitive material prolonged storage mechanical packaging device comprises a
workbench, positioning units are fixedly connected to the upper end of the
workbench, a conveying disc is installed between the positioning units, and a plurality of
machining grooves are annularly formed in the upper end of the conveying disc at equal intervals; an arrangement unit is installed on one side in the
machining groove, a negative pressure box is installed on one side of the conveying disc, and a packaging strip pasting
machine and two vacuum pumps are installed at the upper end of the negative pressure box. The conveying disc comprises an annular plate, an inner annular groove and an outer annular groove are formed in the inner side and the outer side of the middle of the annular plate correspondingly, and a plurality of teeth are annularly distributed in the inner annular groove at equal intervals. According to the heat-sensitive paper roll packaging device, the
plastic film outside the heat-sensitive paper roll subjected to
plastic packaging is shrunk in a vacuumizing mode, so that the
plastic film is attached to the heat-sensitive paper roll packaged inside, heating is not needed in the packaging process, and the problem that the heat-sensitive paper roll is damaged in the packaging process can be avoided.
