DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-Figure 4 A printing and die-cutting in-line machine shown in the figure comprises a conveying roller 1, on the top of which a wetting component, a drying component and a die-cutting machine 2 are respectively installed from right to left. The drying component comprises a first fixed frame 3 in the middle of the top of the conveying roller 1, and an automatically rotatable roller 9 is installed in the middle of the bottom of the first fixed frame 3 through an electric telescopic rod 4 and a mounting frame 5. A pre-pressing roller 13 is installed in the middle of the rotating roller 9, and a water absorption sleeve 14 is detachably installed on the outer wall of the pre-pressing roller 13. A wind nozzle 6 that can blow hot air toward the top of the water absorption sleeve 14 is installed on the top of the inner wall of the mounting frame 5, and an electric heating wire 12 is installed on the inner wall of the wind nozzle 6. The printing and die-cutting in-line machine of the utility model adopts the water absorption sleeve 14 to press and absorb excess water, and adopts the wind nozzle 6 that can blow hot air to dry the water absorption sleeve 14. Such water absorption can ensure the flatness of the cardboard and prevent wrinkles due to direct contact heating and quick drying with the heating roller.

[0021] Furthermore, the air inlet of the air nozzle 6 is connected to the air outlet of the fan 7 through the air duct 8, so as to facilitate the blowing and drying of the water absorption sleeve 14; further, the wetting component includes a second fixed frame 10 installed at the top right end of the conveying roller 1, and a plurality of atomizing nozzles 11 are installed in a linear and equidistant array at the bottom of the second fixed frame 10, so as to facilitate the installation of the atomizing nozzle 11; further, the water inlet of the atomizing nozzle 11 is connected to the water outlet of the water tank 18 through the water pipe 16 and the water pump 17, so as to facilitate the spraying and wetting of the cardboard box; further, the power input end of the rotating roller 9 is connected to the power output end of the motor 15, so as to facilitate the driving of the rotating roller 9 to rotate; further, the water absorption sleeve 14 is detachably installed on the outside of the pre-pressing roller 13 by Velcro, so as to facilitate the disassembly and replacement.

[0022] In this scheme, when in use, the printing and die-cutting in-line machine of the utility model adopts a water absorption sleeve 14 to press and absorb excess water, and adopts a wind nozzle 6 that can blow out hot air to dry the water absorption sleeve 14. In this way, water absorption can ensure that the cardboard is flat and prevent wrinkles due to direct contact heating and quick drying with a heating roller. The external power supply turns on the water pump 17 and the fan 7 through the external switch, and at the same time controls the electric telescopic rod 4 to extend and lower the pre-pressing roller 13. The water pump 17 draws the water in the water tank 18 to the atomizing nozzle 11 through the water pipe 16, and the atomized water is sprayed on the cardboard box. Then the wet cardboard box is conveyed to the pre-pressing roller by the conveying roller 1. 13, the motor 15 drives the pre-pressing roller 13 to rotate, so that the pre-pressing roller 13 is close to the surface of the cardboard box through the outer water absorption sleeve 14 to absorb excess moisture. At the same time, the fan 7 blows air to the air nozzle 6 on the top of the pre-pressing roller 13 through the air duct 8. The cold air is heated by the electric heating wire 12, and the hot air quickly dries the water absorption sleeve 14 on the top of the pre-pressing roller 13, that is, it rotates to the bottom of the water absorption sleeve 14 below to absorb water, and the top of the water absorption sleeve 14 is dried synchronously. Such drying will not cause multiple wrinkles that are difficult to flatten on the cardboard box (the water pump 17, the fan 7 and the electric telescopic rod 4 are all existing products on the market).
