[0002] Tinplate printing mainly refers to printing various patterns on tinplate, and can making refers to making tinplate into various shapes desired by customers to package products for the purpose of beauty and practicality.

[0003] In the iron printing work, the iron sheet needs to be cleaned, dried, coated, baked and other operations. The iron sheet is cleaned and dried so that the iron printing ink can better adhere to the iron sheet. After cleaning, the iron sheet will be placed on the conveyor belt production line and dried by the drying device on the conveyor belt production line.

[0004] For example, a drying device for preparing iron sheets is disclosed in Chinese patent CN220615232U. The drying device for preparing iron sheets avoids excessively high surface temperature of the iron sheets, which affects the effect of the iron printing ink, and improves the iron printing efficiency by setting a preheating mechanism and a drying mechanism. However, the drying device for preparing iron sheets has the following defects while solving the problem:

[0005] The cleaned iron sheet is placed flat on the conveyor belt. When the bottom of the iron sheet is dried, hot air dries the bottom of the iron sheet through the slots on the conveyor belt. However, the principle of drying is to heat water and make it evaporate upwards. Therefore, the moisture on the bottom of the iron sheet needs to be dissipated to both sides after evaporation. However, the bottom of the iron sheet fits the conveyor belt, making it difficult for the evaporated moisture to be discharged upwards, resulting in humidity between the conveyor belt and the iron sheet, resulting in poor drying effect on the bottom of the iron sheet.

[0027] Specifically, a motor 5 is fixedly installed at the bottom of the box body 1, and a transmission shaft 51 is fixedly connected to the output shaft of the motor 5. A bearing seat 53 is fixedly connected to the bottom of the box body 1. The transmission shaft 51 is rotatably connected to the inside of the bearing seat 53. The bearing seat 53 reinforces the transmission shaft 51. A driving bevel gear 52 is fixedly connected to the outer surface of the transmission shaft 51. A driven bevel gear 22 is fixedly connected to the bottom end of the first positioning shaft 2. The driving bevel gear 52 is meshed with the driven bevel gear 22. The motor 5 drives the driven bevel gear 22 to rotate through the driving bevel gear 52, thereby achieving the purpose of driving the first roller shaft 21 to rotate.

[0028] Embodiment 2:

[0029] like Figure 1 and Figure 3 As shown, on the basis of Example 1, a slide groove 6 is provided at the top and bottom of the box body 1, and a slider 32 is slidably connected inside the slide groove 6. The two ends of the second positioning shaft 3 are rotatably connected in the upper and lower sliders 32 respectively. The second positioning shaft 3 can slide in the slide groove 6 through the slider 32, so that the spacing between the second roller 31 and the first roller 21 can be adjusted, so that it is suitable for drying iron sheets of different thicknesses. The top and bottom of the slider 32 are fixedly connected to the limit plate 33 to limit the slider 32 to prevent the slider 32 from falling off the slide groove 6. A spring 61 is fixedly connected inside the slide groove 6, and one end of the spring 61 is fixedly connected to the slider 32.

[0030] Embodiment three:

[0031] like Figure 1-2As shown, on the basis of Example 1 or Example 2, the bottom of the inner wall of the box body 1 is rotatably connected to a plurality of support rollers 12, and the support rollers 12 support the bottom of the iron sheet.

During this process, the second roller 31 slides according to the thickness of the iron sheet, so that the iron sheet can smoothly enter between the first roller 21 and the second roller 31. Then, hot air is delivered to the air pipe 4, so that the hot air is blown to the iron sheet through the air nozzle, thereby heating and evaporating the water on the surface of the iron sheet, and the evaporated water vapor is discharged from the exhaust hole above.

[0033] Compared with the prior art, the present invention has the following beneficial effects:

[0034] 1. The iron sheet is vertically placed between the first roller 21 and the second roller 31, and is transmitted by the rotation of the first roller 21 and the second roller 31, so that when the hot air is blown to the surface of the iron sheet through the air nozzle 41 on the air pipe 4, it is not blocked by any structure. After the water on the surface of the iron sheet is dried, the evaporated water can be discharged upward very smoothly, thereby avoiding the problem of local moisture on the iron sheet, thereby having a better drying effect.

[0035] 2. The second positioning shaft 3 is slidably connected to the slide groove 6 on the box body 1 through the slider 32, and the slider 32 is supported by the spring 61. Therefore, when the iron sheet enters between the first roller 21 and the second roller 31, the second roller 31 can move according to the thickness of the iron sheet, ensuring that the first roller 21 and the second roller 31 can clamp the iron sheet to avoid the problem of the iron sheet tipping over, so that it can be suitable for drying iron sheets of different thicknesses, thereby improving practicality.

[0036] 3. By arranging a support roller 12 at the lower part of the box body 1, after the iron sheet is sent into the box body 1, the support roller 12 supports the bottom of the iron sheet.
