The air at the position of the hole-bearing plate 204 is extracted by the air pump 206 and the vacuum tube 205, thereby adsorbing the plastic packaging bag, and thus realizing the feeding process of the plastic packaging bag;

[0031] After the adsorption is completed, the lifting load-bearing plate 307 is driven by the inlet and outlet electric slide rails 304 and the alignment electric slide rail 306 to reset. The rotary motor 201 drives the porous fixed sleeve 202 to rotate, turning the plastic packaging bag to the top. The linkage electric slide rail 207 drives the support fixing frame 208 to rise, and ink is injected into the grid printing box 210 through the material discharging support pipe 309 and the material discharging fixed box 308. After the feeding is completed, the linkage electric slide rail 207 drives the support fixing frame 208 to move down. The switching electric slide rail 209 drives the grid printing box 210 to move and align to the side end of the plastic packaging bag. The covering electric slide rail 211 drives the covering strip 212 to move along the grid printing box 210, attaching the ink to the plastic packaging bag. After the printing is completed, the linkage electric slide rail 207 drives the support fixing frame 208 to reset. Again, the rotary motor 201 drives the porous fixed sleeve 202 to rotate, driving the plastic packaging bag to the bottom. The matching electric slide rail 301 drives the circulating hot air drying frame 302 to rise and fit to the side end of the porous fixed sleeve 202, and the exhaust fan 303 and the circulating hot air drying frame 302 are used to perform heat circulation treatment on the air to achieve heat circulation drying.
