[0033] In the embodiment, the first conveying assembly 2 comprises two first belt conveyors 21 arranged in an up-down manner, both of which are belt conveyors in the prior art, the conveying directions of the two first belt conveyors 21 are the same, and the length of the upper first belt conveyor 21 is slightly shorter than that of the lower first belt conveyor 21, so as to facilitate feeding to the lower first belt conveyor 21. In this way, the two first belt conveyors 21 can independently realize the moving heating of the screen, further improving the heating efficiency.

[0034] In the embodiment, the heating box 1 is further provided with a heat preservation plate 4 extending along the length direction thereof, the two side portions of the heat preservation plate 4 are connected with the inner walls of the heating box 1 at the two sides in the width direction thereof respectively, and both of the two first belt conveyors 21 are suspended above the heat preservation plate 4. The heat preservation plate 4 can improve the heat preservation performance of the heating box 1, thereby further improving the heating efficiency.

[0035] In the embodiment, the heating box 1 comprises an outer box body 11 and an inner box body 12 arranged in the outer box body 11, the heat preservation plate 4 is arranged in the inner box body 12, a partition cavity 5 is formed between the outer wall of the inner box body 12 and the inner wall of the outer box body 11, the heating assembly 3 is accommodated in the partition cavity 5, and a plurality of air outlets 6 are formed in the inner box body 12 and communicate with the partition cavity 5. In this way, the heat generated by the heating assembly 3 can be dissipated outward through the air outlets 6, so as to heat the screen from the circumferential side of the screen, further improving the uniformity of heating.

[0036] In the embodiment, the partition cavity 5 comprises two first cavities 51 arranged at the two sides in the width direction of the heating box 1 respectively and a second cavity 52 arranged at the upper side of the heating box 1 and communicating with the two first cavities 51. The heating assembly 3 comprises a plurality of electric heating rods arranged in the two first cavities 51 respectively and spaced along the length direction of the heating box 1, the second cavity 52 is provided with an air extraction assembly 7 comprising a plurality of fans arranged along the length direction of the heating box, and the inner box body 12 is further provided with a plurality of air extraction openings 8 communicating with the second cavity 52, the plurality of air extraction openings 8 are located directly below the plurality of fans respectively.
