By making the second support seat, bearing and connecting shaft all located on the outside of the furnace body, compared with embedding the bearing in the furnace body, the heat insulation component set in the furnace body can be used to avoid the bearing being damaged due to overheating, thereby improving the quality of the product. At the same time, because the second support seat is located on the outside of the furnace body and supports the bearing through the second support seat, the second support seat is less likely to be deformed by heat than supporting the bearing through the furnace body, thereby improving the stability of the second support seat supporting the transmission roller. Therefore, the second support seat can support transmission rollers with longer lengths, thereby improving the applicability of the product.

[0021] 7. By fitting the mounting ring with the outer wall of the furnace body, the mounting ring is arranged on the outside of the transmission roller, and the sealing ring is sleeved on the outside of the transmission roller, so that the sealing ring can seal the gap between the furnace body and the transmission roller, thereby avoiding heat loss in the furnace body and improving the product experience.

[0022] 8.

[0023] 9. Due to the strength of the transmission roller, even when the width of the furnace body is large, the transmission roller will not deform or break during rotation, thereby improving product quality. By setting the width of the furnace wall to 2550-5000mm, there is sufficient working space in the furnace body, so that multiple workpieces can be placed in the furnace body at the same time and heated simultaneously, thereby improving product work efficiency.

[0035] The furnace body 10 is configured as a hollow cavity with openings at both ends, so that the workpiece to be heated can enter the front opening of the furnace body 10 and move out from the rear opening of the furnace body 10. A plurality of drive rollers 11 are sequentially passed through the two side walls of the furnace body 10 and are rotatably connected to the furnace body 10, so that the furnace body 10 can support the plurality of drive rollers 11, thereby enabling the plurality of drive rollers 11 to rotate within the furnace body 10. Furthermore, when a workpiece is placed on the drive rollers 11, the rotating drive rollers 11 can drive the workpiece to move. A plurality of support beams 12 are installed on the outside of the furnace body 10, and the gas pipe 13 is installed on the plurality of support beams 12, so that the plurality of support beams 12 support the gas pipe 13, thereby improving the stability of the gas pipe 13.

Since the two second radiant tubes 20 are located below the plurality of drive rollers 11, when heat is injected into the two second radiant tubes 20, the second radiant tubes 20 can heat the workpiece from below.

[0036] When using the product, first connect the air pipe 15 to the air source and the gas pipe 13 to the gas source so that air and gas are injected into the air pipe 15 and the gas pipe 13 respectively; then, place the workpiece to be heat treated on the transmission roller 11; then, open the valves on the air pipe 15 and the gas pipe 13 so that air and gas are injected into the first burner 19 and the second burner 22 respectively; at the same time, open the first burner 19 and the second burner 22 so that the first burner 19 and the second burner 22 ignite the mixed gas of air and gas and generate heat respectively; the heat generated by the first burner 19 will be injected into the two first radiation tubes 17 through the first air valve 18 The heat generated by the second burner 22 is injected into the second radiant tube 20 through the second air valve 21. Because the two first radiant tubes 17 are located above the plurality of drive rollers 11, and the two second radiant tubes 20 are located below the plurality of drive rollers 11, when heat is injected into the two first radiant tubes 17 and the second radiant tubes 20, the two first radiant tubes 17 heat the workpiece from above, while the second radiant tubes 20 heat the workpiece from below, thereby heating the workpiece from all directions. Furthermore, because the exhaust pipe 16 is connected to both the first air valve 18 and the second air valve 21, the exhaust gas generated by the mixing and combustion of air and gas is discharged through the exhaust pipe 16.

By connecting the second support seat 35 to the support plate 31, fitting the bearing 34 onto the outside of the connecting shaft 33, and placing the bearing 34 within the support groove of the second support seat 35, the support plate 31 supports the second support seat 35, thereby enabling the second support seat 35 to support the connecting shaft 33 via the bearing 34, thereby improving the rotational stability of the connecting shaft 33, the connecting cylinder 32, and the transmission roller 11, thereby enabling the connecting shaft 33 to rotate relative to the second support seat 35. By fixing at least two limit screws 36 within the support groove and positioning them outside the bearing 34, the limit screws 36 can limit the bearing 34 and the transmission roller 11, thereby preventing the transmission roller 11 from moving horizontally and improving the rotational stability of the transmission roller 11. By providing a gap between the connecting cylinder 32 and the second support seat 35, interference between the connecting cylinder 32 and the second support seat 35 when the connecting cylinder 32 rotates is avoided, thereby improving product quality.

[0048] With the above structure, by fitting the bearing 34 outside the connecting shaft 33 and placing the bearing 34 within the support groove of the second support seat 35, the second support seat 35 supports the connecting shaft 33, the connecting cylinder 32, and the drive roller 11 through the bearing 34, thereby improving the transmission stability of the drive roller 11. By positioning the second support seat 35, the bearing 34, and the connecting shaft 33 outside the furnace body 10, compared to embedding the bearing 34 within the furnace body 10, the heat insulation assembly provided within the furnace body 10 can be used to prevent damage to the bearing 34 due to overheating, thereby improving product quality. Furthermore, because the second support seat 35 is located outside the furnace body 10 and supports the bearing 34 through the second support seat 35, it is less susceptible to thermal deformation than if the bearing 34 were supported by the furnace body 10. This improves the stability of the second support seat 35 supporting the drive roller 11. Therefore, the second support seat 35 can support longer drive rollers 11, thereby improving the applicability of the product.
