[0026] In this embodiment, the inside of the blowing cover 6 is a cavity structure, and a plurality of air outlet holes 61 are arranged on the concave side of the blowing cover 6.

[0027] Through the cavity structure and the plurality of air outlet holes of the blowing cover 6, the hot air can be blown out more uniformly, avoiding the problem of local overheating or uneven drying of the laminated paper caused by concentrated blowing of hot air, and improving the drying quality and efficiency.

[0028] Please refer to Figure 3 In this embodiment, the outer part of the fixed column 71 is fixedly connected with a mounting disc 74, the side close to the inner heating roller 72 of the mounting disc 74 is provided with a mounting groove 7401, the inside of the mounting disc 74 is provided with three insertion holes 7402 located in the mounting groove 7401, the outer periphery of one end of the outer heat conducting cylinder 75 is rotatably connected with a connecting ring 76, the connecting ring 76 is matched with the mounting groove 7401, the side close to the mounting disc 74 of the connecting ring 76 is fixedly connected with three insertion rods 77, the insertion rods 77 are matched with the insertion holes 7402, and the end of the insertion rod 77 penetrating through the insertion hole 7402 is threadedly connected with a nut 79 abutting against the mounting disc 74.

[0029] Among them, the design of the connecting ring 76 and the insertion rod 77 realizes the butt joint between the outer heat conducting cylinder 75 and the mounting disc 74, and the firmness of the connection is ensured through the nut 79, and at the same time, the detachable design also facilitates the cleaning and maintenance of the heating assembly 7.

[0031] Among them, the blowing cover 6 is an arc-shaped cover plate, and the two blowing covers 6 are respectively located on the upper and lower sides of the two heating assemblies 7.

[0032] It should be noted that the two blowing covers 6 arranged in a staggered manner and respectively distributed on the upper and lower sides of the two heating assemblies 7 can blow hot air on both sides of the laminated paper.

[0033] Working principle: During use, the coated paper is driven by an external winding device (not shown in the diagram) to enter the drying chamber 1 from the inlet on one side and is conveyed through the guide roller 8 and the external heat-conducting cylinder 75. During the conveying process, two blowers 6 blow hot air to both sides of the coated paper to dry it. At the same time, the electric heating wire 73 heats the inner heating roller 72, thereby conducting heat to the external heat-conducting cylinder 75. This allows the coated paper to directly contact the external heat-conducting cylinder 75 for drying during the conveying process. The dried coated paper is then conveyed out from the outlet on the other side of the drying chamber 1.
