[0002] A roller kiln is a widely used ceramic sintering device, which can be used to produce daily-use porcelain, sanitary porcelain, bricks and tiles, electrode materials and other products. Taking an atmosphere-protected roller kiln as an example, its basic working principle is as follows: an electric motor is used to drive multiple rows of roller rods to rotate, and the powder materials contained in graphite crucibles are continuously fed into a closed furnace body dozens of meters long, and after being sintered at a high temperature of about 800 °C, they are taken out of the furnace and enter the next process.

[0035] As shown in the Figure 1 - Figure 6 accompanying drawings, the present utility model provides a roller path driving device, which includes a rotary driving mechanism 10, a driving flexible belt 13, n double-row driving wheels 11 and n - 1 driving flexible belts 12, where n is approximately equal to 3. Among them, the rotary driving mechanism 10 preferably uses a motor, and the driving flexible belt 13 and the driving flexible belts 12 can use belts or chains. The double-row driving wheels 11 can use double-row belt wheels or double-row sprockets. Preferably, both the driving flexible belt 13 and the driving flexible belts 12 use chains, and the double-row driving wheels 11 are double-row sprockets, thereby improving the service life and environmental adaptability and being suitable for the harsh environment of a roller hearth kiln. Taking the double-row sprocket as an example, each double-row sprocket is provided with two sprocket teeth parallel to each other, which can be used to connect two chains;

[0036] The n double-row driving wheels 11 are used to be connected to the driving ends of the n rollers 2 one by one, that is, the driving end of one roller 2 is connected to one double-row driving wheel 11 to drive the roller 2 to rotate. The driving flexible belts 12 connect adjacent double-row driving wheels 11, and the n - 1 driving flexible belts 12 are staggered. At this time, one driving flexible belt 12 connects the corresponding driving wheels on adjacent double-row driving wheels, and except for the double-row driving wheels 11 at the head and the end, the remaining double-row driving wheels 11 are each engaged with two driving flexible belts 12.

The driving flexible belt 13 and the rotary driving mechanism 10 can be set in one group or two groups. When only one group is set, the driving flexible belt 13 and the rotary driving mechanism 10 are correspondingly connected to the double-row driving wheel 11 at the first section or the end. When two groups are set, the driving flexible belt 13 and the rotary driving mechanism 10 are correspondingly connected to the double-row driving wheels 11 at the first section and the end.
