Technical Field

[0001] The invention relates to the technical field of packaging processing equipment, and in particular to a multi-layer composite preparation device for high-barrier packaging materials. Background Art

[0002] High barrier packaging materials are often required for food and medicine packaging. During manufacturing, high barrier packaging materials are mainly melted and extruded by physical methods to form a film with a multi-layer structure. This film combines the advantages of various resins, such as barrier properties, strength, impact resistance, etc., to meet the needs of high barrier packaging.

[0003] At present, when preparing multi-layer composites of packaging boards, a calendering device is required to extrude and shape the coating. The packaging boards are usually stored in warehouses before use, so their surfaces are easily covered with dust. The dust on the surface of the packaging boards will affect the coating coverage, thereby reducing the barrier properties of the packaging materials. In addition, the coating often needs to be cooled and solidified after extrusion and shaping. Current preparation devices need to install separate cooling devices during cooling, which takes up a relatively large space. Summary of the invention

[0004] The present invention provides a multi-layer composite preparation device for high-barrier packaging materials, which can ensure the barrier performance of the packaging materials after coating, while ensuring the processing effect, and combines the extrusion shaping structure with the cooling structure, eliminating the need to install a separate cooling device, thereby reducing occupied space.

The rotating shafts at the front and rear ends of the paint roller are also tubular structures, and the rotating shafts at the front and rear ends of the paint roller are connected to the annular cavity inside them.

[0008] In at least some embodiments, a tilted plate that is higher on the left and lower on the right is provided on the left side of the paint collecting plate, and the left side of the tilted plate is in close contact with the right outer wall of the paint roller, and the top right side of the paint collecting plate is a groove structure.

[0013] The present invention provides a multi-layer composite preparation device for high-barrier packaging materials, which has the following beneficial effects: The dust cleaning box and the brush in the present invention can cooperate to clean the dust on the surface of the packaging board before it comes into contact with the paint, thereby ensuring the barrier performance of the packaging material after the paint is applied. The paint collection plate can also collect excess paint to avoid the paint from contaminating the already applied packaging board, thereby ensuring the processing effect.

[0014] In addition, the paint roller can not only extrude and shape the paint, but also introduce cold air into the cavity inside the paint roller to cool down its shell part.

When the paint in the paint placement box 4 falls on the top outer wall of the paint roller 3, a part of the paint will flow to the right outer wall of the paint roller 3 due to gravity, and then these paints will flow to the top of the tilted plate on the left side of the paint collecting plate 7. Moreover, the blade-shaped structure on the tilted plate on the left side of the paint collecting plate 7 is in close contact with the outer wall of the paint roller 3, which can also prevent the paint on the right outer wall of the paint roller 3 from dripping down and causing pollution to the already squeezed packaging sheet. Finally, the paint will flow into the groove-shaped structure on the top right side of the paint collecting plate 7 along the tilted plate on the left side of the paint collecting plate 7. Later, these paints can be cleaned out and recycled.

Because the openings on the guide baffles 11 are staggered, the cold air can evenly contact the shell part of the paint roller 3 to cool it.

[0024] In the present disclosure, Figure 2 and Figure 8 As shown, the bottom of the brush 10 can be in close contact with the top surface of the packaging board. Four rows of circular holes that penetrate inside and outside are also provided on the bottom outer wall of the dust cleaning box 8, and the four rows of circular holes are respectively located on the right side of the four brushes 10. When using the present device to prepare multi-layer composites of packaging boards, the external vacuum cleaner can be turned on. When the vacuum cleaner is working, the air in the internal cavity of the dust cleaning box 8 will be extracted through the vacuum tube 9 to form a negative pressure. When the packaging board conveying roller 2 drives the packaging board to move to the right, its top surface will contact the brush 10. At this time, the brush 10 can sweep the dust on the surface of the packaging board, and then the dust cleaning box 8 will suck the dust and the air on the top of the packaging board into its internal cavity and into the vacuum cleaner, so that the dust on the surface of the packaging board can be cleaned.

During use, the cold air blown out by the external air cooler will be blown into the annular cavity inside the paint roller 3 through the rotating shaft on the rear side of the paint roller 3, and then the cold air will flow forward in the empty groove separated by the guide baffle 11. After the shell of the paint roller 3 is cooled, it can assist the paint to accelerate the curing, and the copper shell has a higher efficiency in conducting temperature.

During this process, the unloading gear rod 6 will be separated from the open groove on the inner side of the bottom of the paint placement box 4, so the paint in the paint placement box 4 can flow downward. At this time, the paint in the paint placement box 4 will fall onto the top outer wall of the paint pressure roller 3 through the open groove at the bottom thereof. When the packaging sheet conveying roller 2 drives the packaging sheet to move to the right, the packaging sheet The paint roller 3 is driven to rotate counterclockwise, so that the paint on the outer wall of the paint roller 3 can be displaced downward and contact the top surface of the packaging board, so that the paint can be evenly covered on the surface of the packaging board. At the same time, the paint roller 3 can also extrude the paint, and the cold air blown out by the external cooling fan will be blown into the annular cavity inside the paint roller 3 through the rotating shaft on the rear side of the paint roller 3, and then the cold air will flow forward in the empty groove separated by the guide baffle 11. Because the openings on the guide baffle 11 are staggered, the cold air can evenly contact the shell part of the paint roller 3 to cool it down. Finally, the cold air will be blown out outward through the rotating shaft on the front side of the paint roller 3. After the shell of the paint roller 3 is cooled, it can help the paint to solidify faster, and the paint is placed in the box 4. When the paint falls onto the top outer wall of the paint pressing roller 3, a part of the paint will flow to the right outer wall of the paint pressing roller 3 due to gravity, and then the paint will flow to the top of the inclined plate on the left side of the paint collecting plate 7. In addition, the blade-like structure on the inclined plate on the left side of the paint collecting plate 7 is in close contact with the outer wall of the paint pressing roller 3, which can also prevent the paint on the right outer wall of the paint pressing roller 3 from dripping down and causing pollution to the already squeezed packaging sheet. Finally, the paint will flow along the inclined plate on the left side of the paint collecting plate 7 into the groove-like structure on the top right side of the paint collecting plate 7. Later, the paint can be cleaned out and recycled. After use, the electric push rod 5 can be controlled to extend and push the unloading gear rod 6 to move downward. In this process, the unloading gear rod 6 will be embedded in the open groove on the inner side of the bottom of the paint placement box 4.Therefore, the open groove on the inner side of the bottom of the paint placing box 4 can be closed to prevent the paint in the paint placing box 4 from continuing to flow downward.
