Technical Field

[0001] The utility model relates to the technical field of laminated paper production equipment, in particular to a laminated paper production equipment with uniform coating. Background Art

[0002] Laminated paper is a composite material with plastic particles coated on the surface of paper. Its main feature is that this composite material is oil-proof, waterproof and heat-sealed. It is widely used. For example, in the production of paper cups, the processing and production of laminated paper requires the use of a laminating device. Therefore, laminating equipment plays an important role in the production of laminated paper.

[0003] At present, there are some disadvantages of laminating equipment on the market. First, natural air drying or natural cooling is adopted after lamination, which takes a long time to cool down and reduces production efficiency. Secondly, the tension of the paper cannot be adjusted during lamination and coating, which may cause the paper to become loose, offset and misaligned, and affect the lamination effect. Furthermore, the lamination uniformity is not good, which affects the flatness of the film surface. Utility Model Content

[0013] Compared with the prior art, the utility model has the following beneficial effects: good cooling effect, convenient adjustment of the tension of the paper, easy guarantee of film pressing uniformity and film surface flatness;

[0014] (1) The circulation pump allows cold water to enter the film pressing roller from the water inlet pipe, and then enter the cooling layer from the guide pipe, so as to quickly cool down the film material in the cooling layer. The heated water is then cooled down by the condenser and circulated into the cooling layer for cooling. After film pressing, the paper moves to the receiving plate, which increases the moving path of the paper in the rack and is conducive to cooling. The induced draft fan introduces airflow from the outside, passes through the air outlet plate, and cools the film paper on the receiving plate, further improving the cooling effect. The cooling effect is good.

[0015] (2) According to the strength and toughness of the paper, the height of the tensioning roller on the tensioning frame can be adjusted to make the clamping plate slide together, and then the locking bolt is screwed from the middle of the clamping plate to the inside of the middle of the tensioning roller to fix the height of the clamping plate and the tensioning roller. In this way, the tension of the paper can be adjusted to avoid looseness and uneven coating during processing, which is convenient for adjusting the tension of the paper.

[0016] (3) Add plastic particles into the extruder in advance, and move the paper to the coating roller through the change-direction roller, where the coating process is carried out. The film material is coated on the paper through the die head of the extruder. After the paper is coated, it passes through the film pressing roller. The outer wall of the cooling layer outside the film pressing roller is smooth, which makes it easy to press the film evenly, and it is easy to ensure the uniformity of the film pressing and the flatness of the film surface.
