[0002] After the printing press prints the ink on the printing substrate, it still needs to be quickly dried and cured through an infrared lamp box. The ink on the printing substrate needs to be dried by the infrared lamp in the infrared lamp box. However, the infrared lamp in the infrared lamp box is not sufficient to dry the ink on the quickly passing printing substrate (paper), resulting in the ink on the printing substrate passing through the infrared lamp box still being wet. Once it is wound up, it will cause the loss of the ink of the printed pattern or text, which has a great impact. Summary of the Utility Model

[0003] To solve the above problems, the utility model provides a hot air circulation device for a hot air box, aiming to use the infrared lamp box as a hot air box at the same time, and the entering hot air accelerates the drying and curing of the ink on the printing substrate.

The air outlet of the fan is connected to the heating core through a pipeline, the heating core is connected to the air inlet of the hot air box through a pipeline, the air inlet of the fan is connected to the pipeline and connected to the air outlet of the fan. A drawer is also arranged in the hot air box, infrared lamps are sequentially arranged and installed on the drawer, the drawer is detachably connected to the hot air box through a lock, and a drying through slot is arranged on the hot air box, and the drying through slot is arranged above the drawer.

[0005] The heating core includes an outer tube, and four sequentially arranged heating wire groups are arranged in the outer tube.

[0006] A three-way valve is connected to the air inlet of the fan.

[0007] An installation plate is arranged on the drawer, "V"-shaped installation grooves are sequentially arranged on the installation plate, light-emitting lenses are respectively pasted on the two side walls of the "V" installation groove, and infrared lamps are installed in the "V"-shaped installation groove.

[0008] The beneficial effect of the utility model is that infrared lamps are installed in the hot air box at the same time, so that hot air and infrared lamps can simultaneously perform infrared irradiation and hot air drying on the printing substrate passing through the drying through slot, greatly improving the drying and curing efficiency of the ink.

[0009] The following further describes the utility model in conjunction with the drawings and specific embodiments. Brief Description of the Drawings

[0010] Figure 1 It is a three-dimensional view of the specific embodiment of the utility model;

[0011] Figure 2 This is a partial sectional view of the specific embodiment of the present utility model. Specific Embodiment

[0012] The present utility model will be specifically described below through embodiments, which are only used for further illustration of the present utility model and cannot be construed as a limitation on the protection scope of the present utility model.

[0013] As Figure 1 、 Figure 2 shown, this embodiment discloses a hot air circulation device for a hot air box, including a hot air box 1, and further including a fan 2 and a heating core 3. The air outlet 21 of the fan 2 is connected to the heating core 3 through a pipeline, the heating core 3 is connected to the air inlet of the hot air box 1 through a pipeline, and the air inlet 22 of the fan 2 is connected to the pipeline and connected to the air outlet of the fan 2. A drawer 4 is further arranged in the hot air box 1, and infrared lamps 5 are arranged in sequence on the drawer 4. The drawer 4 is detachably connected to the hot air box 1 through a lock. When replacing the infrared lamp, the lock block 7 can be unlocked and the drawer can be pulled out, so that the operator can quickly get off the printing machine, reducing dangerous operations and facilitating the replacement of the infrared lamp. A drying through groove 6 is arranged on the hot air box 1, and the drying through groove 6 is arranged above the drawer 4.

[0014] The heating core 3 includes an outer tube 31, and four heating wire groups 32 arranged in sequence are arranged in the outer tube 31, so that a very sufficient heat source can be provided.

[0015] A three-way valve 8 is connected to the air inlet of the fan 2. Through the three-way valve 8, the hot air can be reused, and the hot air temperature and air volume of the hot air box can also be adjusted.

[0016] The drawer 4 is provided with a mounting plate 41, and "V"-shaped mounting grooves 42 arranged in sequence are arranged on the mounting plate 41. Reflective lenses are respectively pasted on the two side walls of the "V"-shaped mounting grooves 42, and the infrared lamps 5 are installed in the "V"-shaped mounting grooves 42. Through this structure, the infrared lamps 5 can emit light through the reflective lenses on both sides, greatly improving the irradiation efficiency of the infrared lamps 5 and also facilitating the replacement of the infrared lamps 5.

[0017] At the same time, it also has the following advantages: 1. Environmental protection, the hot air circulation can suck away the ink smell;

[0018] 2. The ink can be better cured through the hot air circulation;

[0019] Hot air circulation mode:

[0020] 1. After the fan is started, it blows air, passes through the heating core, and becomes hot air;

[0021] 2. The hot air enters the hot air box (infrared lamp box) through the air duct;

[0022] 3. The infrared light box dries the ink of the printing material through infrared lamp tubes + hot air;

[0023] 4. The hot air of the infrared light box enters the air inlet of the fan through a three-way air valve for circulation;

[0024] 5. The three-way air valve can adjust the hot air temperature and air volume of the hot air box.

[0025] With the above technical solution, the infrared lamp 5 is installed in the hot air box 1 at the same time, so that the hot air and the infrared lamp 5 can simultaneously perform infrared irradiation and hot air drying on the printing substrate passing through the drying trough 6, greatly improving the drying and curing efficiency of the ink.
