[0037] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0038] For examples, see Figure 1-Figure 4 This embodiment provides a screen printing drying device, including: a hot air drying mechanism 100, an infrared drying mechanism 200 and a feeding mechanism 300; the air outlet of the hot air drying mechanism 100 is arranged above the feeding mechanism 300; the infrared drying mechanism 200 is arranged in the air outlet; the feeding mechanism 300 is suitable for pushing the exterior decoration to be dried close to the air outlet of the hot air drying mechanism 100. By setting the infrared drying mechanism 200 for auxiliary drying, the drying time is reduced to only 3-6 seconds, the fluidity of the ink is reduced, the probability of the exterior decoration becoming flowery is reduced, the defective rate of the product is reduced, and the production efficiency is improved.

[0039] Specifically, the infrared drying mechanism 200 includes N infrared lamp tubes 210; the N infrared lamp tubes 210 are fixedly arranged in the air outlet.
