Description

Technical Field

[0001] This utility model relates to the field of paper box coating technology, and in particular to a surface coating device for processing packaging paper boxes. Background Technology

[0002] Paper box lamination involves applying a transparent plastic film to the surface of a paper box using heat pressing, creating a paper-plastic composite product. Specifically, paper box lamination has the following functions:

[0003] Waterproof and moisture-proof: The surface of the cardboard box after lamination has an extra thin and transparent plastic film, which can effectively prevent moisture from entering and protect the contents of the cardboard box from moisture.

[0004] Stain and wear resistant: The plastic film covering makes the cardboard box surface more wear resistant, reducing wear and stains during transportation and use.

[0005] Enhanced aesthetics: The surface of the laminated cardboard box is smoother and shinier, and the colors are more vibrant, which can improve the overall appearance and grade of the product.

[0006] Enhanced protection: The coating also provides protection against chemical corrosion, folding, and heat, further protecting the integrity and lifespan of the cardboard box.

[0007] During the lamination process of cardboard boxes, hot air is used to heat the heat-shrink film on the outside of the box. The heated film gradually shrinks until it tightly covers the box surface. Throughout this process, the box moves on a conveyor belt, meaning at least one side of the box cannot be directly heated. This uneven heating can lead to wrinkles and affect the lamination effect. Utility Model Content

[0008] This utility model discloses a surface coating device for processing packaging paper boxes, which aims to solve the technical problem that uneven heating may cause wrinkling and affect the coating effect.

[0009] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0010] A surface coating device for processing packaging paper boxes includes a coating chamber, a first hot air blower disposed outside the coating chamber, a plurality of first air outlets disposed on the inner wall of the coating chamber, a first conveyor belt connected to the coating chamber, a reversing impact plate disposed at the top of the first conveyor belt, a first guide plate and a second guide plate, a first support shaft movably connected to the inner walls of opposite sides of the coating chamber, a plurality of reversing guide plates equidistantly fixed to the outer periphery of the first support shaft, a servo motor connected to one end of the first support shaft, an air guiding mechanism disposed on opposite sides of the reversing guide plates, a second conveyor belt disposed at the bottom of the coating chamber, and a dust collection mechanism disposed at the top of the second conveyor belt.

[0011] The film-coating chamber has a feed inlet through one side, and the feed inlet is located at one end of the first conveyor belt. The reversing impact plate and the first guide plate are arranged in opposite directions and staggered, and the two second guide plates are distributed on opposite sides of the reversing guide plate.

[0012] The inner walls of the opposite sides of the film-coated compartment are respectively fixedly connected to L-shaped support plates, and the second guide plate is fixed to the top of the L-shaped support plate. The first support shaft passes through the two L-shaped support plates, and the reversing guide plate is located between the two L-shaped support plates.

[0013] Multiple first air outlets are connected to a first hot air blower, and multiple first air outlets are respectively distributed on the top of the film-coated compartment and on the inner walls of opposite sides.

[0014] By setting up a reversing guide plate, a reversing impact plate, a first guide plate, and a second guide plate, the cardboard box can be translated and rotated to change the horizontal adjacent surfaces. When the cardboard box enters the corresponding position of the reversing guide plate, by driving multiple reversing guide plates to rotate, the cardboard box on the reversing guide plate can be flipped and dropped onto the second conveyor belt, thereby completing the longitudinal flipping. Under this structure, each side of the cardboard box can be in direct contact with hot air, and the uniformity of heat shrink film coating can be achieved through uniform heating, thus optimizing the coating effect.

[0015] In a preferred embodiment, the vacuuming mechanism includes two electrostatic plates, a power supply connected to one side of the electrostatic plates, a slide rod fixed to one side of the power supply, and a second fan disposed at the bottom of the coating chamber;

[0016] Each of the power supply units has a support fixedly connected to one side of its outer wall, and a slide rod is fixed to one side of the support. The opposite sides of the film-coating chamber are provided with inclined slide grooves, and the slide rod is movably connected in the inclined slide grooves.

[0017] The outer end of the slide rod is fixedly connected to a handle, and the handle is fitted against the outer wall of the film-coating chamber. The inner walls of the two supports on opposite sides are simultaneously connected to linkage rods.

[0018] The output end of the second fan is fixedly connected to a second air outlet, and the second air outlet passes through the film-covered compartment and is embedded in the bottom inner wall of the film-covered compartment.

[0019] With a dust-collecting mechanism, when the cardboard box falls from the first conveyor belt to the second conveyor surface, the dust on its surface will be splashed up. Then, the second fan at the bottom will guide it upwards, where it can be adsorbed by the electrostatic plate. This adsorption of surface dust particles can prevent dust from adhering and damaging the film during transportation. At the same time, based on the setting of the inclined slide, the position of the electrostatic plate can be moved to adapt to the use of cardboard boxes of different sizes.

[0020] In a preferred embodiment, the air guiding mechanism includes a large-diameter gear, a small-diameter gear meshing with the large-diameter gear, a second support shaft connected to the outer wall of one side of the small-diameter gear, and air guide fan blades equidistantly disposed on the outer periphery of the second support shaft;

[0021] The large-diameter gear is fixedly connected to the first support shaft, and a bearing bracket is connected to one end of the second support shaft, and the bearing bracket is fixed to the inner wall of the coating chamber.

[0022] With the air guiding mechanism, while the servo motor drives multiple guide plates to move, the transmission of small-diameter gears can simultaneously drive multiple guide fan blades to rotate rapidly. When the cardboard box falls onto the surface of the second conveyor belt, the dust that is shaken up can be guided towards the electrostatic plate by the airflow under the action of the guide fan blades. By providing unilateral wind force compensation, it is easier for the dust to be adsorbed by the electrostatic plate, thus optimizing the cleaning effect.

[0023] As described above, a surface coating device for processing packaging paper boxes includes a coating chamber, a first hot air blower disposed outside the coating chamber, multiple first air outlets disposed on the inner wall of the coating chamber, a first conveyor belt connected to the coating chamber, a reversing impact plate disposed at the top of the first conveyor belt, a first guide plate and a second guide plate, a first support shaft movably connected to the inner walls of opposite sides of the coating chamber, multiple reversing guide plates equidistantly fixed to the outer periphery of the first support shaft, a servo motor connected to one end of the first support shaft, air guiding mechanisms disposed on opposite sides of the reversing guide plates, a second conveyor belt disposed at the bottom of the coating chamber, and a dust collection mechanism disposed at the top of the second conveyor belt. The surface coating device for processing packaging paper boxes provided by this utility model has the technical effect of achieving uniform heating of the paper box in every direction, ensuring the coating effect.

After being sorted by the first guide plate 11 and the second guide plate 12, it enters the corresponding reversing guide plate 14. Then, under the action of the servo motor 3, multiple reversing guide plates 14 are driven to rotate through the first support shaft 15.

After being sorted by the first guide plate 11 and the second guide plate 12, it enters the corresponding reversing guide plate 14. Subsequently, under the action of the servo motor 3, multiple reversing guide plates 14 are rotated through the first support shaft 15.
