[0029] A total of thirty-two shuttles are provided for transporting in seventeen furnaces; molds for positioning the glass are provided on the shuttles.

[0030] Workflow:

[0031] 1. The shuttle returns to the loading position, manually take the corresponding glass and put it on the trolley mold, and press the start button;

[0032] 2. The shuttle car rises to the upper part of the first section of the furnace body and automatically performs a circulating motion.

[0033] 3. The shuttle car in the lower part of the second section of the furnace body arrives at the origin of the loading glass, and the hot-formed glass is manually taken out and placed on the glass rack. The corresponding glass to be formed is manually taken out and placed on the mold. When the hot forming time in the forming area is in place, the shuttle car will cycle in sequence;

[0034] 4. After the upper shuttle car enters the 10th section of the furnace body, there are heating wires on the top of the 10th to 17th sections of the furnace body. By controlling the temperature of each section of the furnace body, the glass is gradually heated up and reaches the molding temperature at the 17th section.

[0035] 5. The shuttle car descends from the upper part of the 17th section to the lower part. When it runs to the lower part of the 16th section, external cooling air enters from the bottom to cool the glass, thus reaching the annealing process.

[0036] 6. After the lower shuttle car enters the 9th section of the furnace body, the fans in the lower part of the 2nd to 9th sections of the furnace body cool the glass.
