Description

Technical Field

[0001] The utility model relates to the technical field of printing machines, and particularly relates to a drying device for an ink-water two-color printing machine. Background Technique

[0002] A printing machine is a machine for printing characters and images. Modern printing machines generally consist of mechanisms such as plate loading, ink coating, printing, and paper feeding (including folding). Its working principle is as follows: First, the characters and images to be printed are made into printing plates and installed on the printing machine. Then, ink is applied to the areas with characters and images on the printing plate by manual or the printing machine, and then directly or indirectly transferred to paper or other printing substrates (such as textiles, metal plates, plastics, leather, wooden boards, glass, and ceramics), thereby replicating the same printed matter as the printing plate.

[0003] Existing printing machines are usually equipped with drying devices to quickly dry ink and water. However, traditional drying devices use hot air to dry. During the drying process, when the hot air contacts the object, it will disperse around, resulting in rapid loss of hot air. To ensure the drying efficiency and keep the drying device running continuously, a large amount of energy is wasted. In view of the above problems, this application designs a drying device for an ink-water two-color printing machine. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1-4 , a drying device for an ink and two-color printing press, including a base 1, a drying chamber 2 is fixed to the top end of the base 1, a plurality of conveying roller shafts 3 are rotatably connected to the top end of the base 1, the conveying roller shafts 3 are located directly below the drying chamber 2, a hot air box 4 is fixed to the top end of the drying chamber 2, a blower 5 is fixed to the top end of the hot air box 4, the blower 5 passes through the top end of the hot air box 4, a plurality of heating strips 6 are fixed inside the hot air box 4, a plurality of air outlets 7 are opened at the bottom end of the hot air box 4, an inlet 8 and an outlet 9 are respectively opened on the left and right sides of the drying chamber 2, air return openings 10 are opened on the front and rear inner walls of the drying chamber 2, transmission devices 11 are installed at both the front and rear ends of the drying chamber 2, the transmission devices 11 are communicated with the air return openings 10, the inside of the conveying roller shaft 3 is provided as a cavity, a plurality of transmission pipes 12 are communicated at the bottom end of the transmission device 11, the transmission pipes 12 are communicated with the conveying roller shaft 3 and are rotatably connected thereto, air leakage openings 13 are opened at both ends on the outer wall of the conveying roller shaft 3, and the air leakage openings 13 are communicated with the cavity of the conveying roller shaft 3.

[0023] When the device is in use, start the heating strip 6 to heat the air in the hot air box 4, and at the same time start the blower 5. Under the action of the blower 5, the heated hot air is blown out from the air outlet 7. The object to be dried is transported above the conveying roller shaft 3 through the conveying device, and the hot air blows on the object for drying. At the same time, after the hot air contacts the object, it will disperse around. Starting the transmission device 11 can absorb the dispersed hot air through the air return opening 10 and then transfer it to the cavity of the conveying roller shaft 3 through the transmission pipe 12. Through heat conduction, the conveying roller shaft 3 is heated, and at the same time, part of the hot air is blown out from the air leakage opening 13 to dry the bottom of the object.

[0024] In actual use, it is found that the heat is lost relatively quickly in the drying chamber 2. To alleviate the above problems, in this embodiment, a heat radiation plate 14 is fixed to the inner wall of the drying chamber 2.

[0025] In actual use, it is found that it is not convenient to control the drying temperature. To solve the above problems, in this embodiment, a temperature controller 15 is installed on the hot air box 4, the temperature controller 15 is connected to the heating strip 6, and the temperature controller 15 can control the internal temperature of the hot air box 4.

[0026] It is found in actual use that when hot air moves in the transmission tube 12, heat loss will occur. In order to alleviate the above problem, in this embodiment, the transmission tube 12 is set to a material with strong heat insulation performance.

[0027] It is found in actual use that the dried objects tend to accumulate at the outlet 9. To avoid the above problem, in this embodiment, the top of the base 1 is located on the right side of the outlet 9 and is configured as a downwardly inclined slope.

[0028] It is found in actual use that the dried objects are not easy to be collected in a centralized manner. In order to solve the above problem, in this embodiment, a collection bin 16 is fixed to the right end of the base 1 .
