DETAILED DESCRIPTION

[0020] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0021] like Figure 1-Figure 3 As shown, an automatic film coating and transportation device for a tile-type paper box comprises a bottom plate 1, two mounting plates 2 are fixed on the top surface of the bottom plate 1, a fixing plate 15 is fixed between the two mounting plates 2, a second electric push rod 16 is fixed to the bottom of the fixing plate 15, a concave plate 17 is fixed to the telescopic end of the second electric push rod 16, a second drive motor 18 is fixed to the bottom of the concave plate 17, a plurality of fan blades 19 are fixed at equal angles on the outer wall of the output end of the second drive motor 18, an extrusion cylinder 20 is rotatably arranged in the concave plate 17, two rotating shafts 3 are rotatably arranged between the two mounting plates 2, a first drive motor 4 is fixed on one side of the mounting plate 2, the rotating shaft 3 penetrates the mounting plate 2 and is connected to the output end of the first drive motor 4, a conveyor belt 5 is arranged on the periphery between the two rotating shafts 3, a plurality of heating cylinders 8 are arranged on one side of the mounting plate 2, a guide plate 6 is fixed between the two mounting plates 2, the cross section of the guide plate 6 is triangular, the tip of the guide plate 6 is in contact with the conveyor belt 5, and a fixing rod 7 is fixed between the two mounting plates 2.

[0022] During use, the staff starts the first driving motor 4, and drives the rotating shaft 3 to rotate through the output end of the first driving motor 4. At this time, the tile-shaped paper box on the conveyor belt 5 is driven to move through the rotating shaft 3. During the forward movement of the tile-shaped paper box, it will first pass through the heating cylinder 8. Under the action of the heating cylinder 8, the surface of the tile-shaped paper box is heated. At this time, the tile-shaped paper box will contact the inclined surface of the guide plate 6. After contacting the inclined surface of the guide plate 6, one side of the tile-shaped paper box is driven to tilt up through the inclined surface of the guide plate 6. At this time, the tile-shaped paper box will contact the film between the stretching plate 11 and the fixing rod 7, and the conveyor belt 5 will continue to drive the tile-shaped paper box to move. At this time, the film on the film-coating rod 13 will follow the movement of the tile-shaped paper box and cover the tile-shaped paper box. The surface of the tile-shaped paper box is heated by the heating cylinder 8 to ensure that the film is more docile when covering the tile-shaped paper box, and the second electric push rod 16 drives the extrusion cylinder 20 to press the film to remove bubbles, thereby further improving the waterproof performance and overall quality of the product.

[0023] At this time, the conveyor belt 5 will drive the tile-type paper box to move to the bottom of the fan blade 19. At this time, the staff starts the second drive motor 18, and drives the fan blade 19 to rotate through the output end of the second drive motor 18, so as to cool the tile-type paper box, which is beneficial for the tile-type paper box to quickly cool down after it is heated and softened by the heating cylinder 8 and contacts with the film. Due to the principle of thermal expansion and contraction, the film quickly adheres to the surface of the tile-type paper box. Then the staff starts the second electric push rod 16, and drives the extrusion cylinder 20 to move downward through the telescopic end of the second electric push rod 16, so that the outer wall of the extrusion cylinder 20 can press the film on the surface of the tile-type paper box. The small bubbles in the depressions on the surface of the film can be removed through the rapid pressing of the extrusion cylinder 20 to avoid bubbles between the film and the paper box, thereby avoiding affecting the waterproofness of the tile-type paper box and improving the appearance quality of the tile-type paper box after lamination. The automated stretching, heating, cooling and pressing process reduces the need for manual operation, speeds up the production process, and improves the work efficiency of the production line.

[0024] like Figure 1-Figure 4 As shown, support plates 9 are fixed to the top surfaces of the two mounting plates 2, and slide grooves 12 are respectively provided on the two sides of the two support plates 9 close to each other, a first electric push rod 10 is fixed in one of the slide grooves 12, and a stretching plate 11 is fixed to the telescopic end of the first electric push rod 10, a laminating rod 13 is rotatably arranged between the two support plates 9, and a baffle 14 is fixed between the two support plates 9.

[0025] During use, after the staff wraps the film around the laminating rod 13, they can pull one end of the film so that the film fits against the side of the stretching plate 11 away from the baffle 14, and pull one end of the film downward again, and wrap one end of the film around the fixed rod 7, and then start the first electric push rod 10. The telescopic end of the first electric push rod 10 drives the stretching plate 11 to move backward, which is conducive to stretching the film, so that the film between the stretching plate 11 and the fixed rod 7 is in a taut state, ensuring that the film is in a taut state during the laminating process, avoiding the film wrinkling phenomenon, and improving the appearance quality of the tile-type paper box after lamination.

[0026] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
