[0026] The embodiments of the present utility model will now be described in detail with reference to the accompanying drawings. To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions of the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of the present utility model, but not all embodiments.

[0027] Therefore, the following detailed description of the embodiments of the present invention provided in conjunction with the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0028] Example 1

[0029] like Figures 1-7 As shown, the label coating drying device provided in this embodiment includes an oven body 1. The oven body 1 includes an upper box 101 and a lower box 102 that are rotatably connected. The two are rotatably connected by a hinge structure. In use, multiple oven bodies 1 are connected end to end. The oven has a space inside for conveying label products and hot air, so as to dry the label products.

[0030] Here, an air guiding mechanism 2 is provided inside the upper housing 101. The air guiding mechanism 2 includes an outer cover 10, multiple air outlet plate groups 20 provided at the bottom of the outer cover 10, an air inlet 30 provided at the top of the outer cover 10, and two air guiding plates 40 provided inside the outer cover 10. The air inlet 30 is connected to the air collection space 11.

[0031] The outer cover 10 includes two side plates 12 and a top plate 13 disposed on the upper part of the two side plates 12. The middle part of the top plate 13 is horizontally disposed, and the two sides of the middle part are slightly inclined downwards, forming an opening below the outer cover 10, thereby forming an air collection space 11 inside the outer cover 10. The air outlet plate assembly 20 is disposed on the opening, and the top plate 13 has an opening that is connected to the air inlet 30.
