Description
Technical Field
[0001] The utility model relates to a gravure printing machine, in particular to an environmentally friendly gravure printing machine with an odor treatment mechanism, belonging to the technical field of printing machines. Background Art
[0002] In the prior art, for example, a utility model with publication number 202020525719.8 discloses a printing press with a deodorization function. By using the exhaust fan on the mounting frame inside the processing hood, it is possible to blow air to the printed paper roll or cloth roll that has passed through the rotating roller to improve the efficiency of drying the ink. By using the electric heating wire, after the personnel turns on the electric heating wire, the exhaust fan can blow hot air to the paper passing through the rotating roller, so that the ink on the printed paper dries faster and has a high-efficiency color fixing effect. By setting up a UV photolysis purifier, the personnel arranges the exhaust end duct of the UV photolysis purifier outdoors and turns on the UV photolysis purifier, so that the air inlet end of the UV photolysis purifier exhausts the air to the suction duct through the exhaust duct, which greatly improves the printing quality and avoids the situation where the ink is not dry in humid weather or environment.

DETAILED DESCRIPTION
[0024] In order to make the technical solution of the utility model more clear and specific to those skilled in the art, the utility model is further described in detail below in conjunction with embodiments and drawings, but the implementation methods of the utility model are not limited thereto.
[0025] like Figure 1-Figure 4 As shown, the present embodiment provides an environmentally friendly gravure printing machine with an odor treatment mechanism, comprising an ink box 1, a plate roller 2 is rotatably mounted on one end of the top of the ink box 1, a printing roller 3 is rotatably mounted on the top of the plate roller 2, a drying box 4 is arranged at the end of the top of the ink box 1 away from the plate roller 2, a purifier 5 is arranged on the top of the drying box 4, an exhaust fan 6 is arranged on one side of the drying box 4, the input end of the exhaust fan 6 is connected to the inside of the drying box 4, the output end of the exhaust fan 6 is connected to the input end of the purifier 5, an upper hollow box 7 is arranged on the inner top of the drying box 4, exhaust ports 13 are evenly opened on the bottom of the upper hollow box 7, a lower hollow box 9 is arranged on the inner bottom of the drying box 4, a spacing adjustment mechanism is arranged between the upper hollow box 7 and the lower hollow box 9, a circulation pipe 8 is arranged between the output end of the purifier 5 and the lower hollow box 9, a heating plate 10 is fixed to the inner top of the lower hollow box 9, and a telescopic tube 12 is arranged between the bottom end of the upper hollow box 7 and the lower hollow box 9.
[0026] The overall working principle is as follows: after the substrate passes between the impression roller 3 and the plate roller 2, the ink is pressed onto the bottom of the substrate, and then the substrate passes through the interior of the drying box 4. At this time, the heating plate 10 is located on the printing surface of the substrate, and the exhaust port 13 at the bottom of the upper hollow box 7 is aligned with the upper surface of the substrate. The heating plate 10 is powered on to generate heat to dry the substrate, and at the same time, the exhaust fan 6 and the purifier 5 are turned on to extract the odorous gas inside the drying box 4 into the interior of the purifier 5 for purification, and then flow back to the interior of the lower hollow box 9. After being heated again by the heating plate 10, it enters the interior of the upper hollow box 7, and the hot air is sprayed onto the upper surface of the substrate through the exhaust port 13. The substrate is dried simultaneously by using different heating methods on both sides, which not only has a fast drying rate, but also does not cause the flow of the printed ink, and has a better drying effect.
[0027] In this embodiment, the openings at both ends of the drying box 4 are located at the same horizontal plane as the top of the plate roller 2 , and the length of the openings at the ends of the drying box 4 is greater than the length of the plate roller 2 .
[0028] Partial working principle: When the printing material passes through the opening and enters the interior of the drying box 4, it is transported horizontally and does not rub against the opening, thereby ensuring the transportation stability of the printing material.
[0029] In this embodiment, a shield is fixed on the top of the drying box 4 near one end of the plate roller 2 , and the shield is located on the top of the impression cylinder 3 .
[0030] Partial working principle: The use of the shield can block dust and prevent it from sticking to the printed matter, thus ensuring the printing effect.
[0031] In this embodiment, a guide plate 11 is fixed to one side inside the lower hollow box 9, and a gap is left between the end of the guide plate 11 and the other side of the lower hollow box 9. The guide plate 11 is located at the bottom of the heating plate 10, and the conducting position of the telescopic tube 12 and the lower hollow box 9 is close to the fixed connection between the guide plate 11 and the inner side of the lower hollow box 9.
[0032] Partial working principle: After the gas discharged from the purifier 5 enters the lower hollow box 9, it is guided by the guide plate 11, which can increase the residence time of the gas in the lower hollow box 9 and ensure the heating effect.
[0033] In this embodiment, the guide plate 11 is parallel to the heating plate 10 , and the top of the heating plate 10 is parallel to the bottom surface of the upper hollow box 7 .
[0034] Partial working principle: Since the substrate passes through the interior of the drying box 4 in parallel, the heating plate 10 and the upper hollow box 7 are respectively parallel to the substrate, which can ensure the drying rate and effect.
[0035] In this embodiment, the spacing adjustment mechanism includes a transmission bin 14, a rotating rod 15, a first bevel gear 17, a bidirectional screw 18 and a second bevel gear 19. The transmission bin 14 is located on the outside of the drying box 4, and the bidirectional screw 18 is vertically rotatably installed on the inside of the drying box 4. The two ends of the bidirectional screw 18 are respectively threadedly connected to the upper hollow box 7 and the lower hollow box 9. The second bevel gear 19 is installed at the middle position of the bidirectional screw 18. The rotating rod 15 is installed through the side of the transmission bin 14, and the rotating rod 15 is connected to the transmission bin 14. The end of the rotating rod 15 located inside the transmission bin 14 is installed with a first bevel gear 17 meshing with the second bevel gear 19.
[0036] Local working principle: During use, due to the different thickness of the printing material, in order to ensure the drying effect, it is necessary to adjust the distance between the upper hollow box 7 and the lower hollow box 9. At this time, the rotating rod 15 drives the rotation of the first bevel gear 17, and the first bevel gear 17 drives the second bevel gear 19 to rotate. The second bevel gear 19 drives the bidirectional screw 18 to rotate, thereby changing the distance between the upper hollow box 7 and the lower hollow box 9.
[0037] In this embodiment, an adjusting wheel 16 is fixed to one end of the rotating rod 15 away from the first bevel gear 17 , and an anti-slip pattern is provided on the outer side of the adjusting wheel 16 .
[0038] Partial working principle: The setting of the adjusting wheel 16 can facilitate the manual rotation of the rotating rod 15.
[0039] The above is only a further embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the scope disclosed by the present invention according to the technical solution and concept of the present invention, which fall within the protection scope of the present invention.
