The front end of the conveyor roller 5 passes through the front end of the strip plate 2 and is inserted into the inner side of the bearing seat 3. The rear end of the conveyor roller 5 passes through the rear end between the strip plates 2. A drive sprocket 12 is provided at the rear end of the conveyor roller 5. A drive chain 13 is provided between the outer sides of the drive sprocket 12. When firing ceramic products, the blank is placed on the conveyor roller 5. The reduction motor 11 is started and one side of the conveyor roller 5 rotates. The drive sprocket 12 and the drive chain 13 drive the conveyor roller 5 to rotate in the same direction and transport the ceramic blank into the kiln body 1 for firing. Smoke exhaust pipes 4 are provided on both sides of the top of the kiln body 1. During the firing process, exhaust gas is discharged through the smoke exhaust pipes 4.

[0024] As a further implementation of this embodiment, such as Figures 1-4 As shown, a fixed frame 7 is installed at the middle position of both sides of the top of the kiln body 1. An electric cylinder 9 is inserted through the top of the fixed frame 7. Adjustable gates 10 are installed on both sides of the kiln body 1. The vertical cross-section of the adjustable gate 10 is "L"-shaped. The bottom end of the electric cylinder 9 is fixedly connected to the middle position of the top of the adjustable gate 10. By driving the adjustable gate 10 to move up and down through the electric cylinder 9, the opening height of the adjustable gate 10 can be adjusted to adapt to the height of the ceramics and other ceramic products to be fired, which improves the applicability of the roller kiln and enhances economic efficiency. A heat insulation plate 15 is installed on the inner side of the adjustable gate 10, and it can also be closed during the firing process. The gate 10 seals the kiln body 1 and uses the heat insulation plate 15 to isolate the heat inside the kiln, thereby reducing the rate of heat loss during firing and improving energy efficiency. The bottom of both ends of the inner side of the gate 10 is provided with limiting sliders 16, and the two ends of both sides of the kiln body 1 are provided with stabilizing slide rails 14. The stabilizing slide rails 14 are symmetrically arranged on one side of the kiln body 1. The limiting sliders 16 are embedded in the inner side of the stabilizing slide rails 14, and the limiting sliders 16 can slide up and down inside the stabilizing slide rails 14. When the gate 10 is raised or lowered, the limiting sliders 16 slide up and down inside the stabilizing slide rails 14 accordingly, thereby achieving the purpose of limiting and stabilizing the gate 10.

[0025] During use, the electric cylinder 9 drives the regulating door 10 to move up and down, while the slider 16 moves up and down within the stabilizing slide rail 14 to limit and stabilize the regulating door 10. Thus, the opening height of the regulating door 10 can be adjusted to suitably meet the height requirements of the ceramics and other ceramic products to be fired. During the firing process, the regulating door 10 can also be closed to seal the kiln body 1, while the heat insulation plate 15 is used to isolate the heat inside the kiln.

[0026] As a further implementation of this embodiment, such as Figures 1-4 As shown, limiting guide components are provided at both ends of the outer side of the conveyor roller 5. The limiting guide components include a ring-shaped limiting plate 6. The limiting plate 6 is provided at both ends of the outer side of the conveyor roller 5 and is symmetrically arranged on the outer side of the conveyor roller 5. When conveying ceramic products to be fired via the conveyor roller 5, the ring-shaped limiting plate 6 is used to limit, guide and stabilize them. A stabilizing bullseye wheel 17 is provided on the inner side of the limiting plate 6. The stabilizing bullseye wheel 17 is arranged in a ring at equal intervals on the inner side of the limiting plate 6. If the moving ceramic product comes into contact with the limiting plate 6, it can be transmitted and conveyed through the stabilizing bullseye wheel 17 to avoid the ceramic product being blocked by the limiting plate 6. This ensures the smoothness of the ceramic product during conveying, thereby effectively preventing the ceramic product from colliding with the inner wall of the kiln and breaking or being damaged, and preventing uneven firing due to being too close to one side of the kiln body 1 during the conveying process.

[0027] When conveying ceramic products to be fired through conveyor roller 5, a ring-shaped limiting plate 6 is used to limit, guide and stabilize them. If the moving ceramic products come into contact with the limiting plate 6, they can be conveyed through the stabilizing bullseye wheel 17 to avoid the ceramic products being blocked by the limiting plate 6.

[0028] Working principle: When using a high-temperature roller kiln, firstly, the high-temperature burner 8 is turned on to heat the kiln body 1 to the firing temperature. Then, the ceramic blank is placed on the conveyor roller 5, and the reduction motor 11 is started to rotate one side of the conveyor roller 5. Through the transmission sprocket 12 and transmission chain 13, the conveyor roller 5 rotates in the same direction, conveying the ceramic blank into the kiln body 1 for firing. At the same time, according to the size of the ceramic blank, the opening and closing electric cylinder 9 drives the adjusting gate 10 to move up and down to adjust the opening height of the adjusting gate 10. Simultaneously, the limiting slider 16 moves up and down within the stabilizing slide rail 14 to adjust the adjusting gate 10. The system is stable and the circular limiting plate 6 is used to limit and guide the ceramic products to be fired when they are conveyed through the conveyor roller 5. If the moving ceramic products come into contact with the limiting plate 6, they can be conveyed through the stabilizing bullseye wheel 17 to prevent the ceramic products from being blocked by the limiting plate 6. During the firing process, the regulating door 10 can be closed to seal the kiln body 1. At the same time, the heat insulation plate 15 is used to isolate the heat in the kiln to reduce the rate of heat loss. Meanwhile, the exhaust gas is discharged through the exhaust pipe 4. After the ceramic products are fired, the regulating door 10 is lifted by the opening and closing electric cylinder 9 and the products are conveyed out through the conveyor roller 5.

[0029] The above are merely preferred embodiments of the present utility model and do not limit the present utility model. Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall fall within the protection scope of the present utility model.
