Technical Field

[0001] The present application relates to the technical field of glass substrate production, and in particular to an annealing furnace internal partition adjustment device and an annealing furnace. Background Art

[0002] In the process of glass substrate production, the annealing furnace plays a key role in adjusting the quality of glass molding. Parameters that affect glass quality, such as glass stress and warping, are all adjusted in the annealing furnace area.

[0003] In the process setting, it is necessary to set different power combinations for the heating units in each zone to establish a suitable temperature field, and the establishment of the temperature gradient inside the annealing furnace is achieved by the partitions between the zones. According to the different glass states, each zone needs to have a temperature difference of different sizes. Limited by the furnace structure and environmental influences, the partitions in some zones of the original annealing furnace are fixed on the furnace body and cannot be adjusted. Sometimes they cannot fully meet the process requirements. If the temperature difference needs to be further adjusted, a more precise zoning adjustment device is required to isolate the temperature of each zone.

[0004] For example, CN111574037A discloses an annealing furnace with controllable opening, which includes a furnace body, a plurality of partition plates, and a driving unit. The plurality of partition plates are arranged in the furnace body, and the driving unit is arranged outside the furnace body. The driving unit is connected to the plurality of partition plates, and the partition plates are adjusted by the driving unit. However, the structure of the driving unit is relatively complex, and in actual use, transmission problems are prone to occur, thus making it difficult to adjust the partition plates.

[0040] The internal partition adjustment device of the annealing furnace has a relatively simple structure and does not require a complex transmission mechanism.
