When hot air flows to one end, far away from the hot box 243, of the pipeline 242, the hot air can flow out through the spray head 2423, the spray head 2423 enables the hot air to flow more dispersedly, therefore, the hot air is more uniformly distributed between the heat preservation cover 244 and the wind blocking plate 241, most of ink on the paper 3 can be fully contacted with the hot air, and the purpose of reducing the possibility that the ink on the paper 3 is not dried is achieved.
Referring to fig. 2 and 3, a gap is formed between the two positioning mechanisms 23, and in the working process of the hot air mechanism 24, hot air flows below the wind shield 241 after passing through the wind shield 241, and at the moment, the hot air can directly flow to the upper surface of the paper 3 through the gap between the two positioning mechanisms 23, so that the upper surface of the paper 3 can be in contact with the hot air more sufficiently, and the purpose of reducing the possibility that ink on the paper 3 passing through the drying device 2 is not dried is achieved.
The implementation principle of the high printing quality printing machine based on the stable paper transmission in the embodiment of the application is as follows: in the using process, firstly, the printing device 1 prints the paper 3 to be printed, then the printing device 1 conveys the printed paper 3 to the upper part of the first conveyor belt 221 of the drying device 2, then the pressing block 231 abuts against the margins on both sides of the upper surface of the paper 3, and at this time, the pressing block 231, the paper 3 and the first conveyor belt 221 move at the same speed, and since the spring 232 is in a compressed state, the pressing piece 231 presses the sheet 3 against the upper surface of the first conveyor belt 221, so that the degree of the fluttering of the sheet 3 with respect to the first conveyor belt 221 due to the flow of the air current can be reduced, further, the position stability of the paper 3 with respect to the first conveyor belt 221 is high, so that the possibility of spreading of the undried ink on the paper 3 can be reduced, the possibility of generating shadows at the printing position on the paper 3 by the printer is reduced, and the purpose of improving the printing quality of the printer is achieved.
The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
