[0026] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0027] The terms “left,” “right,” “front,” “back,” “up,” and “down” mentioned in the following description are oriented in the viewing direction of the front view.

[0028] Example 1: In some embodiments, please refer to the accompanying drawings of the specification. Figure 1-Figure 5 A film printing and drying device includes a drying box 1. The drying box 1 is equipped with a lifting and temperature regulating component 3 for rotating, drying and temperature regulating different types of printed films. The lifting and temperature regulating component 3 includes a drying temperature regulating component 31 and a lifting and rotating component 32. The drying temperature regulating component 31 is installed on the top of the drying box 1, and the lifting and rotating component 32 is installed on the bottom wall of the drying box 1. The drying temperature regulating component 31 is connected to the lifting and rotating component 32. The lifting and rotating component 32 is connected to a film transmission component 2 for feeding and collecting the film. The film transmission component 2 is installed inside and on the right side of the drying box 1.

[0029] When the present invention is used, when it is necessary to dry the printed film, the drying box 1 dries the film as a whole, and the film transmission component 2 further heats the surface of the film while transmitting and collecting the film. The drying and temperature regulating component 31 generates hot air to heat the film and generates cold air to cool the dried film; the lifting and rotating component 32 adjusts the height to adapt to the ink drying time at different times, and rotates at the same time to adjust the blowing angle of the drying and temperature regulating component 31 to achieve rapid drying of the film.

The rotating shafts at both ends of the receiving drum 23 are respectively rotatably connected to the two ends of the top of the mounting base 21. The film transmission assembly 2 also includes heating drums 24. The heating drums 24 are provided in three groups. The left heating drum 24 and the right heating drum 24 are respectively rotatably connected to the inner walls on both sides of the top of the drying box 1 via rotating shafts. The rotating shaft of the middle heating drum 24 is connected to the lifting and rotating assembly 32. The middle heating drum 24 is located below and between the left and right heating drums 24. The top sides of the left and right heating drums 24 are flush with the openings on the two side walls of the drying box 1.

[0031] When the present invention is used, when it is necessary to transport the film, the unprinted end of the film is inserted from the opening on the left, passes through the three heating cylinders 24, and then passes through the opening on the right and is fixed on the receiving cylinder 23. At this time, the printed part of the film successively passes around the top side of the left heating cylinder 24, the bottom side of the middle heating cylinder 24, and the top side of the right heating cylinder 24. The motor 22 drives the receiving cylinder 23 to rotate, and the receiving cylinder 23 drives the film to be wound to the right. The film slides on the surface of the heating cylinder 24, and the film is wound at the receiving cylinder 23 after being dried in the drying box 1. The height difference of the three heating cylinders 24 extends the drying path of the film in the drying box 1, and the heating cylinder 24 can also simultaneously dry the surface of the film.

The input of the left end of the cold air duct 314 is connected to the output of another external fan.

[0034] When the present invention is used, when it is necessary to accelerate the drying of the film, hot air is generated by the heater, and the fan blows the hot air out from the hot air pipe 311, blows it into the sleeve 312, and blows it out through the first air nozzle 313, thereby accelerating the drying of the film; when it is necessary to collect the film, another fan blows cold air out from the cold air pipe 314, and blows it out from the second air nozzle 315, thereby cooling the dried film for easy collection.

[0035] Preferably, there are six nozzles 1 313 equidistantly distributed on the bottom transverse tube of the sleeve 312, and six nozzles 2 315 equidistantly distributed on the right end of the cold air duct 314.

[0037] When the present invention is in use, when it is necessary to change the drying time, the cylinder 321 drives the connecting seat 322 to move downward, and the connecting seat 322 drives the central heating tube 24 to move downward along the slide groove 324, thereby extending the distance between the heating tubes 24. At the same time, the central heating tube 24 drives the connecting rod 323 to move downward, and the connecting rod 323 drives the sleeve 312 to move downward, and the sleeve 312 drives the air nozzle 313 to move downward, thereby realizing the synchronous adjustment of the film drying position by the air nozzle 313; when it is necessary to change the blowing angle of the air nozzle 313, the output end of the motor in the motor box 325 drives the bottom shaft of the sleeve 312 to rotate, the hose sleeve 312 can be bent, and the sleeve 312 drives the air nozzle 313 to rotate, thereby adjusting the blowing angle and achieving the best drying effect.
