[0022] Please refer to Figures 1 to 4 , in the embodiment of the present utility model, a constant pressure belt tensioning device for photovoltaic processing includes a sintering furnace 10 for sintering solar photovoltaic cells and a photovoltaic belt 3. The photovoltaic belt 3 is made of soft metal wire. The photovoltaic belt 3 passes through the sintering furnace 10. Both side edges of the photovoltaic belt 3 are fixedly connected with chains 4. A second sprocket 5 and a first sprocket 18 are meshed and connected at both ends inside each chain 4. A second rotating rod 16 passes through and is fixedly connected between the two second sprockets 5. Both ends of the second rotating rod 16 are respectively rotatably connected with second legs 9. One end of the second rotating rod 16 is provided with a driving device. The driving device includes a support plate 7. The support plate 7 is fixedly connected to the side wall of one of the second legs 9. A motor 6 is fixedly connected to the upper side of the support plate 7.

When the motor 6 is started, the motor 6 can drive the two second sprockets 5 to rotate through the second rotating rod 16, and the two second sprockets 5 then drive the photovoltaic belt 3 to rotate and move through the two chains 4.

[0023] Specifically, a first rotating rod 17 penetrates and is fixedly connected between two first sprockets 18. Both ends of the first rotating rod 17 are connected to first legs 13 through a tightness adjusting device. Both of the two first legs 13 and the two second legs 9 are fixedly connected to the ground. Each tightness adjusting device includes a lower cross bar 14, a top cross bar 1, a vertical rod 15, and a telescopic cylinder 11. The bottom side wall of the lower cross bar 14 is fixedly connected to the first leg 13. The top cross bar 1 and the lower cross bar 14 are respectively fixedly connected to the upper and lower ends of the vertical rod 15. One end of the telescopic cylinder 11 is fixedly connected to the side wall of the vertical rod 15, and the other end of the telescopic cylinder 11 is fixedly connected to a moving plate 12. The moving plate 12 is slidably connected between the top cross bar 1 and the lower cross bar 14.

[0026] When the motor 6 is started, the motor 6 can drive two second sprockets 5 to rotate through the second rotating rod 16. The two second sprockets 5 then drive the photovoltaic mesh belt 3 to rotate and move through the two chains 4, so that the photovoltaic mesh belt 3 drives the solar photovoltaic cells into the sintering furnace 10 for sintering;

[0027] When the photovoltaic mesh belt 3 passes through the sintering furnace 10, the photovoltaic mesh belt 3 made of metal material will be heated and thermally expanded and contracted, thereby causing the photovoltaic mesh belt 3 to become loose. At this time, the two telescopic cylinders 11 can be controlled to drive the moving plates 12 to move, so that the photovoltaic mesh belt 3 is tightened to maintain the conveying effect of the photovoltaic mesh belt 3.
