[0021] refer to Figure 1 The worker places the glass sheet after silk screen printing on the first supporting platform 5 of the first rising part 6, and conveys the glass sheet upward and to the lower right through the first conveying chain 4. Then, at the position of the turning part 9, the glass sheet on the first supporting platform 5 transitions to the second supporting platform 12 of the second rising part 10, and then driven by the second conveying chain 13, the glass sheet is conveyed on the vertical plane, and is dried by the drying mechanism 3 during the conveying process. The device allows the glass sheet to be conveyed and dried on the vertical plane, effectively utilizing the upper space. Compared with the traditional horizontal conveying method, the device has a higher space utilization rate.

[0022] refer to Figure 2-Figure 4 The first supporting platform 5 includes a first supporting shaft 14 with a horizontally arranged axis and fixed to the first conveying chain 4, a first suspension bracket 15 is rotatably connected to the first supporting shaft 14, and a first horizontally arranged first E-shaped plate 16 is fixedly connected to the bottom of the first suspension bracket 15; the second supporting platform 12 includes a second supporting shaft with a horizontally arranged axis and fixed to the second conveying chain 13, a second suspension bracket 18 is rotatably connected to the second supporting shaft, and a horizontally arranged second E-shaped plate 17 is fixedly connected to the bottom of the second suspension bracket 18, and the second E-shaped plate 17 can pass through the first E-shaped plate 16 when moving upward.

[0023] The device makes the first E-shaped plate 16 be hung on the front side of the first conveying chain 4 in a rotating manner, and makes the second E-shaped plate 17 be hung on the rear side of the second conveying chain 13 in a rotating manner. The first E-shaped plate 16 and the second E-shaped plate 17 are always in a horizontal state by the rotating hanging method. The glass sheet is placed on the first E-shaped plate 16.
