Detailed Implementation

[0018] The present invention will now be described in further detail with reference to the accompanying drawings.

[0019] Combined with appendix Figure 1-3 A curing device for metal plate printing includes a support base 1, a drying top box 2 on the top of the support base 1, and a drive shaft 3 and a driven shaft 4 rotatably mounted at both ends of the support base 1 below the drying top box 2. Both ends of the drive shaft 3 and the driven shaft 4 are equipped with synchronous belt structures 5. The synchronous belt structures 5 require relatively high precision to ensure that the synchronous belt structures 5 on both sides move synchronously. The synchronous belt structures 5 are equipped with multiple support baffle structures 6, as shown in the figure. The synchronously moving synchronous belt structures on both sides synchronously drive the multiple support baffle structures 6 for transport operations. Simultaneously, the support baffle structures need to be tilted to ensure that the unprinted side is tilted on the support baffle structure 6 during transport. The support base 1 has feeding structures 7 at both ends, one for feeding and the other for conveying.

[0020] The feeding structure 7 includes an outer drive shaft 8 and an inner auxiliary shaft 9 rotatably mounted on both sides of the support baffle structure 6. Both ends of the drive shaft 8 and the end of the auxiliary shaft 9 are equipped with drive wheels 10. The drive wheels 10 on the same side are equipped with a transmission belt 11. As shown in the figure, the transmission belt 11 is located on both sides of the support baffle structure 6. During feeding, the printed metal plate can be transported forward by the transmission belts 11 on both sides, and then lifted by the support baffle structure 6. It is then tilted and transported forward, and then dried by the drying top box 2. After drying, the metal plate is moved to the upper part of the feeding structure 7 at the rear end and transported outward by the transmission belts 11 on both sides. The support baffle structure 6 with a corresponding density can perform efficient drying in a small area. The outer side of the support base 1 is equipped with a motor structure 30 that drives the drive shaft 3 and drive shaft 8 to rotate. The motor structure 30 can drive the drive shaft 3 and drive shaft 8 to actively drive the operation.

[0021] The support base 1 has an external hot air input structure 12 and a circulating hot air input structure 14 on its two sides at the bottom, and the drying top box 2 has a hot air discharge circulation structure 13 that is connected to the circulating hot air input structure 14 at the top.

[0022] The external hot air input structure 12 includes a first air distribution pipe 15. A hot air input pipe 17 is provided on the outside of the first air distribution pipe 15. The hot air input pipe 17 needs to be connected to an external hot air production device. The hot air production device is a common existing device, so it will not be described in detail. Multiple first hot air pipes 16 extending to the bottom of the support base 1 are provided on the inside of the first air distribution pipe 15. Multiple first air outlets 27 are provided in the support base 1. That is, through the setting of multiple pipes, it can be ensured that the hot air input can perform drying operations on the internal hot air input from all directions.

[0023] The circulating hot air input structure 14 includes a second air distribution pipe 22. The outer side of the second air distribution pipe 22 is provided with a circulating hot air pipe 23 that communicates with the hot air discharge circulation structure 13. The inner side of the second air distribution pipe 22 is provided with a plurality of second hot air pipes 21 extending to the bottom of the support base 1. The second hot air pipes 21 are located in the support base 1 and are provided with a plurality of second air outlets 28. The circulating hot air input structure 14 can perform hot air recycling operations. As shown in the figure, the first hot air pipe 16 and the second hot air pipe 21 are staggered. The circulating hot air input structure 14 can relatively reduce the energy consumption used for hot air drying and fixing.

[0024] The hot air exhaust circulation structure 13 includes multiple exhaust pipes 18 located at the top of the drying top chamber 2. These exhaust pipes 18 share a common air collection plate 19. The top of the air collection plate 19 is equipped with a suction pump 20 connected to the circulating hot air pipe 23. The hot air exhaust circulation structure 13, through multiple pipes and the suction pump 20, can input circulating hot air drawn from above into the circulating hot air pipe 23. The drying top chamber 2 is equipped with a gas sensor 29. The suction pump 20 has an exhaust pipe 24. The exhaust pipe 24 and the circulating hot air pipe 23 are respectively equipped with a first electrically controlled valve 25 and a second electrically controlled valve 26. The internal gas sensor 29 includes a temperature and humidity module, which can control the first and second electrically controlled valves 25 and 26 based on temperature and humidity to select whether internal hot air enters the circulation and is discharged externally. A harmful gas concentration detection module can also be added; if the internal harmful gas concentration is high, external discharge can also be performed.

This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto.
