Detailed Description
The embodiment of the application discloses a high-quality double-sided two-color printing machine for book printing. Referring to fig. 1, a high-quality two-sided two-color printing machine for book printing includes a printing machine body 1, and a feeding end of the printing machine body 1 is provided with a feeding mechanism 11 for conveying paper into the printing machine body 1. The end of the printing machine body 1 far away from the feeding mechanism 11, namely the blanking end of the printing machine body 1, is provided with a collecting mechanism 12 for collecting the printed and processed paper. A first curved pipe 2 which is horizontally arranged is arranged between the material collecting mechanism 12 and the printing machine body 1, and a heating component 3 which is used for conveying hot air into the first curved pipe 2 is arranged at the air inlet end of the first curved pipe 2. Carry the hot gas flow through heating element 3 in to first curved pipe 2, the hot gas flow contacts with the paper that has printed, dries the paper, makes the printing ink on the paper be difficult for printing and dyeing on other papers, is convenient for improve the quality of printing processing.
Referring to fig. 1, the first curved pipe 2 includes a first straight pipe 21, a curved pipe 22, and a second straight pipe 23. First straight tube 21 and second straight tube 23 all level sets up, and the central axis is parallel to each other, and second straight tube 23 is located the top of first straight tube 21, and first straight tube 21 is connected with printing machine body 1. The air inlet end of the first straight pipe 21 is communicated with the air outlet end of the heating component 3, and one end, far away from the heating component 3, of the first straight pipe 21 is communicated with the curved pipe 22. The curved pipe 22 is integrally C-shaped, one end of the second straight pipe 23 is connected with one end of the curved pipe 22 far away from the first straight pipe 21, and one end of the curved pipe 22 far away is connected with the second curved pipe 4.
Referring to fig. 1 and 2, the heating assembly 3 includes a fan 31, a plurality of heating wires 32 are inserted into an air inlet of the fan 31, and the heating wires 32 may be heating wires, which can be heated when being powered on, or may be a pipeline through which hot oil is passed. An air outlet of the fan 31 is connected with one end of the first straight pipe 21 far away from the curved pipe 22. After the fan 31 is started, the air near the air inlet of the fan 31 enters the fan 31, and contacts the heating wire 32 during the air entering, so that the temperature is raised and the air is changed into hot air. And then transported by the fan 31 into the first straight pipe 21.
Referring to fig. 3, one side of the first straight pipe 21 close to the second straight pipe 23 and one side of the second straight pipe 23 close to the first straight pipe 21 are both provided with a plurality of air outlets 24, the air outlets 24 on the first straight pipe 21 are both provided with a bending pipe 25 connected with the first straight pipe 21, similarly, the air outlets 24 on the second straight pipe 23 are both provided with a bending pipe 25 connected with the second straight pipe 23, and the bending pipe 25 can be bent at will, specifically, in this embodiment, the bending pipe 25 is set as a gooseneck pipe. The hot air flow entering the first curved pipe 2 is partially ejected from the bent pipe 25 to contact with the paper, and the ink on the paper is dried.
Referring to fig. 1 and 3, one end of the bent tube 25 away from the air outlet 24 is flared, and the end with a larger opening area is located at the end of the bent tube 25 away from the air outlet 24, so as to increase the coverage area of the hot air flow in the bent tube 25 after being ejected. And a screw cap 26 is connected to one end of the bent pipe 25 far away from the air outlet 24 in a threaded manner, and the screw cap 26 is used for plugging the bent pipe 25. A magnetic member 27 for attracting the first curved tube 2 is fixedly connected to the screw cap 26, and the magnetic member 27 is a magnet piece.

After the hot air flow in the second straight pipe 23 enters the second curved pipe 4, the flow speed is reduced due to the enlarged space, the second curved pipe 4 absorbs the heat of the hot air flow, the temperature of the second curved pipe is increased, and then the heat is conducted to the air on the outer periphery side. The paper is subjected to pre-drying as it passes adjacent to the second curved duct 4.
The implementation principle of the high-quality double-sided two-color printing machine for book printing in the embodiment of the application is as follows: after the paper printing process is finished, the paper passes through the lower part of the second curved pipe 4 from the discharging end of the printing machine body 1, and then passes through the space between the first straight pipe 21 and the second straight pipe 23. When the paper passes through, the second curved pipe 4 pre-dries the paper, then the hot air flow in the first curved pipe 2 contacts with the upper and lower surfaces of the paper to dry the printing ink on the paper, and finally the paper enters the material collecting mechanism 12. Because the printing ink on the paper is dried, the stability is higher, and the printing ink on the paper is not easy to be printed on other paper, so that the printing quality is convenient to improve.
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.
