Description

Technical Field

[0001] This utility model relates to the field of thin film composite technology, and in particular to a three-in-one production line that selectively combines lamination dry process and solvent-free composite process. Background Technology

[0002] To meet the diverse needs of packaging films and bags, multilayer composite films are increasingly being used in various fields. As essential production equipment for film lamination, laminating machines, especially those capable of completing three-layer lamination in a single operation, are gaining popularity. With the increasing diversity of market product requirements, the three-in-one process necessitates the combination of various adhesives to meet different three-in-one process structures. However, existing three-in-one laminating machines can only provide one type of adhesive coating and lamination for a fixed coating process, failing to accommodate multiple adhesive types. When different adhesive coating types, such as solvent-based and solvent-free adhesives, are required, either a two-in-one laminating machine is needed for two lamination processes, or additional dedicated three-in-one laminating equipment is required, leading to either reduced efficiency or increased equipment costs. Summary of the Invention

The principle of this invention is that by selectively activating the coating unit and the oven, and by replacing different coating units, the dry and solvent-free three-in-one composite processes can be freely switched to adapt to the coating process requirements of different composite materials.

[0013] The present invention will be further described below with reference to the accompanying drawings.

[0014] like Figure 1 , 2As shown, a three-in-one production line selectively combining lamination dry process and solvent-free composite process includes a first unit 1, a second unit 2, a third unit 3, and a fourth unit 4. The first unit 1, second unit 2, and third unit 3 are arranged sequentially from left to right. A first connecting plate 5 is provided between the top of the first unit 1 and the top of the second unit 2, and a second connecting plate 6 is provided between the top of the second unit 2 and the top of the third unit 3. In this embodiment, the fourth unit 4 can be located to the right of the third unit 3, i.e., the first unit 1, second unit 2, third unit 3, and fourth unit 4 are arranged sequentially from left to right, or the fourth unit 4 can be located on the second connecting plate 6. The first unit 1 includes a first wall panel, a second coating unit 11, and a first composite unit 12.
