[0002] A shuttle kiln is a type of ceramic kiln commonly used for producing ceramic vessels and tiles. Characterized by a long, narrow hearth, it produces uniform firing temperatures, adapting to various types and sizes of ceramic pieces. During firing, the temperature and atmosphere can be adjusted by controlling the combustion and exhaust systems to achieve different firing styles and effects.
[0003] Traditional shuttle kiln flue sealing systems typically utilize a single tooth row combined with a refractory damper to achieve flue sealing and opening. While this method meets basic sealing requirements, it has certain drawbacks. For example, a single tooth row has fewer support points, resulting in relatively poor stability and prone to deformation or damage in high-temperature environments, which in turn affects flue sealing effectiveness and kiln temperature control.

[0009] Furthermore, isolation blocks are fixedly provided on both sides of the rotating shaft bracket, and one side of the isolation block is located outside the edge of the transmission gear.
[0010] Furthermore, the positioning slide rail includes a round rod guide rail, which passes through both sides of the vehicle body frame. A limiting circular plate is fixedly provided at one end of the round rod guide rail, and a limiting gasket and a limiting nut are provided at the other end of the round rod guide rail and are connected by threaded engagement.
