[0016] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the protection scope of the present utility model.

[0017] Specific embodiments are given below.

[0018] Refer to Figure 1 and Figure 2 , a printing machine cooling and drying device, including an outer support plate 1 and an inner support plate 2. The inner support plate 2 is installed on the outer support plate 1 in a lifting manner. Two first back printing guide rollers 3 are installed at the top of the side wall of the inner support plate 2, a first front printing guide roller 4 is installed at the bottom of the side wall of the inner support plate 2, an ice roller 5 and a UV lamp 6 are installed in the middle of the inner support plate 2, and a lamp cover 7 is installed on the side of the UV lamp 6 facing the ice roller 5. A roller seat 8 is installed on the outer support plate 1, and a second back printing guide roller 9 and a second front printing guide roller 10 are installed on the side wall of the roller seat 8 from top to bottom.

[0019] An air cylinder base 11 is installed on the outer support plate 1, an air cylinder 12 is installed on the air cylinder base 11, an air cylinder connecting block 15 is installed on the inner support plate 2, and the telescopic end of the air cylinder 12 is connected to the air cylinder connecting block 15. Guide rails 13 are symmetrically installed on the outer support plate 1, and sliders 14 that slide along the guide rails 13 are installed on the inner support plate 2. The air cylinder 12 works to drive the inner support plate 2 to lift and lower. When the inner support plate 2 lifts and lowers, the sliders 14 move along the guide rails 13 to play a guiding role.

[0020] When the inner support plate 2 rises, it is used for printing on the back of the printing material. The direction in which the printing material envelopes the ice roller 5 is counterclockwise; when the inner support plate 2 descends, it is used for printing on the front of the printing material. The direction in which the printing material envelopes the ice roller 5 is clockwise.

[0021] The air cylinder 12 works to drive the inner support plate 2 to lift and lower. When the inner support plate 2 lifts and lowers, the sliders 14 move along the guide rails 13 to play a guiding role. When the inner support plate 2 rises, at this time the printing material passes under the ice roller 5, over the tops of the two first back printing guide rollers 3, and over the top of the second back printing guide roller 9. At this time, it is used for printing on the back of the printing material, and the direction in which the printing material envelopes the ice roller 5 is counterclockwise. When the inner support plate 2 descends, at this time the printing material passes under the ice roller 5, under the bottoms of the two first front printing guide rollers 4, and over the top of the second overall printing guide roller 10. At this time, it is used for printing on the front of the printing material, and the direction in which the printing material envelopes the ice roller 5 is clockwise.
