Description

Technical Field

[0001] The utility model relates to the technical field of printing machines, in particular to a carton printing and drying device. Background Art

[0002] A printing press is a machine that prints text and images. Modern printing presses generally consist of mechanisms such as plate loading, inking, embossing, and paper feeding (including folding). Its working principle is as follows: the text and image to be printed are first made into a printing plate and mounted on the printing press. Ink is then applied to the areas of the plate where the text and image are located, either manually or by the printing press. The ink is then directly or indirectly transferred to paper or other substrates (such as textiles, metal plates, plastics, leather, wood, glass, and ceramics), thereby reproducing a printed product identical to the printing plate. After the printing process, the printing press generally uses hot air drying equipment to dry the printed ink quickly to form a shape. Currently, the drying equipment of printing presses directly heats the air through a heating device and then feeds the heated air into the printing unit. However, these heating devices for drying have the problem of high energy consumption, which increases the operating cost of the printing press. Utility Model Content

However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0019] like Figure 1-3 As shown, the carton printing and drying device described in this embodiment includes a printing unit 1, a drying box 2 is provided on the top of the printing unit 1, a heating mechanism 12 is provided in the drying box 2, and an air inlet pipe group and an air outlet pipe group are also provided on the drying box 2;

[0020] The air inlet pipe group includes a heat exchanger arranged in the drying box 2, and a first air inlet pipe 3 and a second air inlet pipe 4 are respectively provided at both ends of the heat exchange gas. The first air inlet pipe 3 and the second air inlet pipe 4 both extend to the outside of the drying box 2. The end of the second air inlet pipe 4 is also connected to a third air inlet pipe 5. The third air inlet pipe 5 extends along the top of the drying box 2 to the inside of the drying box 2;

[0021] The air outlet pipe group includes an air outlet main pipe 6 connected to the drying box 2 , the air outlet main pipe 6 is connected to a diversion transverse pipe 7 , and a plurality of air outlet branches 8 extending into the printing unit 1 are evenly distributed on the diversion transverse pipe 7 .

[0022] The heat exchanger is arranged at the air distribution joints 9 on both sides of the drying box 2. Several heat exchange tubes 10 are evenly distributed between the air distribution joints 9. The first air inlet pipe 3 is connected to the air distribution joint 9 on one side, and the second air inlet pipe 4 is connected to the air distribution joint 9 on the other side.

[0023] A plurality of heat exchange fins 11 are evenly distributed on the heat exchange tube 10 .

[0024] The arrangement of multiple groups of heat exchange tubes 10 can divert the air so that it can be heated quickly, thereby improving the heating efficiency of the air. The setting of the heat exchange fins 11 is used to increase the heating area of the heat exchange tubes 10. Genori improves the overall heat exchange efficiency of the heat exchanger.

[0025] An air supply fan 13 is provided on the first air inlet pipe 3 , and the air supply fan 13 is used to supply air into the entire air inlet pipe group and then transport it into the drying box 2 .

[0026] An air distribution pipe 14 is provided at one end of the air outlet branch pipe 8 located in the drying box 2. Air outlet holes 14a are evenly distributed on the air distribution pipe 14. The air distribution pipe 14 can transport heated air to the printing unit 1 for drying operation.

[0027] An air outlet fan 15 is provided on the air outlet main pipe 6 .

[0028] Preferably, the heating mechanism 12 is an electric heating rod or an infrared heater.

[0029] The working principle of the present invention is as follows: the heating mechanism 12 is started to heat the drying box 2. At this time, the air supply fan 13 and the air outlet fan 15 are started respectively. The air supply fan 13 draws the external air into the first air inlet pipe 3, and then enters the air distribution joint 9 on one side of the drying box 2. Then the air is diverted through multiple heat exchange pipes 10 and finally collected in the air distribution joint 9 on the other side. When the air flows in the heat exchange pipe 10, it exchanges heat with the heat in the drying box 2, thereby heating the air inside it. The collected air enters the interior of the drying box 2 through the second air inlet pipe 5 and the third air inlet pipe 5. When the air flows in the air inlet pipe group, the temperature in the drying box 2 will preheat the air. In this way, the air flowing into the drying box 2 is directly hot air, which reduces the rapid heating of the air and saves energy consumption. The preheated air enters the drying box 2 and is heated for the second time by the heating mechanism 12. Then, the heated air is transported along the air outlet main pipe 6 to the diversion cross pipe 7 through the air outlet fan 15. Then, the hot air flows into the air distribution pipe 14 located in the printing unit 1 after being diverted by the air outlet branch pipe 8. Finally, the hot air is dissipated through the air outlet holes 14a on the air distribution pipe 14. The dissipated hot air flows in the printing unit. As the printing machine runs, the printed materials are printed and transported in the printing unit 1, and the hot air heats and dries the printed ink, thereby achieving rapid drying of the ink.
