The connecting cylinder (25) compresses the spring (27), so that the connecting cylinder (25) and the mounting cylinder (5) are docked together; Step 3: Start the electric telescopic rod (14) to extend, the output end of the electric telescopic rod (14) pushes the movable plate (18) to move downward, the movable plate (18) drives the first externally threaded tube (19), the first internally threaded tube (23), the heating cover (17), the second support bar (29), and the second support ring (30) to move downward, so that the second support bar (29), the second support ring (30) cooperate with the first support bar (6), and the first support ring (28) to squeeze the paper dinner plate, and at the same time start the first air delivery pump (9), the first air delivery pump (9) pumps the wet The humid air in the air box (11) is transported to the inside of the gas main pipe (7), the gas main pipe (7) transports the humid air to the inside of the first connecting pipe (8) and the movable pipe (2), the first connecting pipe (8) transports the humid air to the inside of the first externally threaded pipe (19), the first internally threaded cylinder (23), and the heating cover (17), so as to moisten the upper surface of the paper lunch box, and the movable pipe (2) transports the humid air to the inside of the connecting cylinder (25), the mounting cylinder (5), the second externally threaded pipe (20), and the second internally threaded cylinder (21) in sequence, so as to moisten the lower surface of the paper lunch box; Step 4: While the heating cover (17) near the input port (16) is squeezing the paper lunch box, other paper lunch boxes far from the input port (16) are also squeezed by the heating cover (17) and dried by the electric heater (24) inside the heating cover (17). At the same time, the second air pump (12) is started. The second air pump (12) transports the humid air inside the heating cover (17) and the drying box (1) to the inside of the humid air box (11) through the heating cover (17), the first internally threaded cylinder (23), the first externally threaded tube (19), and the second connecting tube (13). The above-mentioned actions are repeated to continuously dry the paper lunch boxes.
