SPECIFIC EMBODIMENT

[0020] The utility model will be further described below in combination with the drawings and specific embodiments.

[0021] As shown in the drawings, Figure 1 — Figure 3 The embodiment discloses a water-based ink high-speed printing drying structure, which comprises the following components and connection relationships:

[0022] 1. The oven 1 is a rectangular metal shell, and a plurality of heating wires 11 are arranged horizontally inside. The heating wires 11 are adjusted in heating power by an electric control system to adapt to different printing speeds and ink types. The oven 1 is provided with an air blower 12 on the top or side. The blowing port of the air blower 12 is connected with the air inlet pipe 28 of the lamp box 2 through a flexible high-temperature-resistant air pipe, and the air inlet port of the air blower 12 is communicated with the air outlet pipe 29 of the lamp box 2 through another air pipe, so as to form a hot air closed circulation loop.

[0023] 2. The main body structure of the light box 2 comprises a main box body 23, a heat insulation pad 24, a top plate 25, a lamp holder 26, a wind guide baffle 27, an air inlet pipe 28 and an air outlet pipe 29.

[0024] The main box body 23 is a closed shell assembled together, and a heating and drying channel 21 is formed inside the main box body 23, which extends along the direction in which the printed matter travels.

[0025] The lamp holder 26 is formed by stamping a steel plate and is in a long strip shape, and is fixed in the main box body 23 along the length direction of the heating and drying channel 21. The upper surface of the lamp holder 26 is provided with six installation grooves arranged in parallel, and the installation grooves are open downwardly toward the heating and drying channel 21. One infrared lamp heating pipe 22 is installed in each installation groove, and the axis of the infrared lamp heating pipe 22 is perpendicular to the direction in which the printed matter travels, so as to ensure that the radiation surface covers the width of the channel.

[0026] The wind guide baffle 27 is a thin steel plate or a high-temperature-resistant alloy plate, which is tightly attached to the bottom surface of the lamp holder 26 and forms a cross-section groove-shaped air inlet chamber 210 with the lamp holder 26. A plurality of air inlet grooves are formed in the wind guide baffle 27, and the groove openings are opposite to the air inlet chamber 210. The inlet end of the air inlet pipe 28 is fixed at the inlet position of the air inlet chamber 210, so that the hot air from the drying oven 1 first enters the air inlet chamber 210 and then is uniformly distributed into the heating and drying channel 21 through the air inlet grooves from the side of the infrared lamp heating pipe 22.

[0027] The heat insulation pad 24 is a high-temperature-resistant heat preservation material plate, which is attached to the inner end surface of the top plate 25, and the one end surface thereof faces the heating and drying channel 21, so as to effectively prevent heat from escaping upwardly and improve the energy utilization rate.

[0028] 3. The backflow and circulation structure The outer edge of the wind guide baffle 27 and the inner bottom of the main box body 23 form a backflow chamber 211. A plurality of backflow holes 212 are formed in the position close to the edge of the wind guide baffle 27. After the hot air in the heating and drying channel 21 completes the drying of the printed matter, the hot air can enter the backflow chamber 211 through the backflow holes 212. The outer wall of the main box body 23 is provided with the air outlet pipe 29, the inlet end of the air outlet pipe 29 is communicated with the backflow chamber 211, and the outlet end is connected to the air inlet of the air blower 12 of the drying oven 1, so as to realize the re-heating and recycling of the hot air.

[0029] 4. After the printing process, the printed matter enters the heating and drying channel 21 of the light box 2. At this time, the heating wire 11 in the oven 1 is electrified to heat the air, and the air blower 12 sends hot air into the air inlet chamber 210 of the light box 2 through the air inlet pipe 28. The hot air enters the heating and drying channel 21 uniformly through the air inlet groove of the air guide partition 27 and passes by the infrared lamp heating pipe 22. The infrared radiation emitted by the infrared lamp heating pipe 22 directly acts on the ink layer, accelerating the evaporation and curing of the solvent; at the same time, the hot air convectively heats the surface of the printed matter, realizing light-heat combined drying. The hot air passes through the channel and enters the backflow chamber 211 through the backflow hole 212, and then returns to the oven 1 through the air outlet pipe 29 to be reheated, forming a closed hot air circulation.

[0030] 5. Advantage embodiment

[0031] The infrared lamp heating pipes 22 are arranged in sequence along the channel to ensure uniform radiation heating;

[0032] The air inlet chamber 210 formed by the air guide partition 27 and the lamp holder 26 realizes uniform distribution of hot air, avoiding local overheating or cooling;

[0033] The circulating air path composed of the backflow chamber 211 and the backflow hole 212 significantly reduces heat loss and has obvious energy-saving effect;

[0034] The overall structure is compact, easy to disassemble and assemble, and suitable for integration into a high-speed printing production line.
