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 four-unit sequential 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

[0003] The technical problem to be solved by this utility model is to provide a three-in-one production line that selectively combines four-unit sequential dry process and solvent-free composite process, which can realize the selective combination of various composite processes such as all solvent-free, dry process + solvent-free, and all dry composite three-in-one, reduce production costs and improve equipment utilization.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is: a three-in-one production line that selectively combines a four-unit sequential dry process with a solvent-free composite process, comprising, from left to right or right to left, a first unit, a second unit, a third unit, and a fourth unit. A first connecting plate is provided between the top of the first unit and the top of the second unit; a second connecting plate is provided between the top of the second unit and the top of the third unit; and a third connecting plate is provided between the top of the third unit and the top of the fourth unit. The first unit includes a first unwinding unit and a first composite unit; the second unit includes a second unwinding unit and a first coating unit; the third unit includes a third unwinding unit and a second coating unit; and the fourth unit includes a rewinding unit and a second composite unit. A first drying oven is provided on the first connecting plate, and a second drying oven is provided on the third connecting plate. The principle of this utility model is that by selectively activating the coating unit and the drying oven, and by changing different coating units, the dry process and the solvent-free three-in-one composite process can be freely switched to adapt to the coating process requirements of different composite materials.

[0005] As an improvement, the first unit, the second unit, the third unit, and the fourth unit are arranged in order from left to right.

[0006] As an improvement, the first unit further includes a first wall panel, the first unwinding unit is located on the lower right side of the first wall panel, and the first coating unit is located on the upper part of the first wall panel; the second unit further includes a second wall panel, the second unwinding unit is located on the lower right side of the second wall panel, and the first coating unit is located on the lower left side of the second wall panel; the third unit further includes a third wall panel, the third unwinding unit is located on the lower right side of the third wall panel, and the second coating unit is located on the lower left side of the third wall panel; the fourth unit further includes a fourth wall panel, the winding unit is located on the lower left or right side of the fourth wall panel, and the second coating unit is located on the upper part of the fourth wall panel.

[0007] As an improvement, the first film material of the first unwinding unit passes sequentially below the first oven, through the first coating unit, through the first oven, and through the second composite unit; the second film material of the second unwinding unit passes sequentially above the first oven and through the first composite unit; the first film material and the second film material are laminated at the first composite unit to form a two-layer composite film; the two-layer composite film passes sequentially above the first oven, above the second oven, and through the second composite unit; the third film material of the third unwinding unit passes sequentially through the second coating unit, through the second oven, and through the second composite unit; the two-layer composite film and the third film material are laminated at the second composite unit to form a three-layer composite film and are then wound up in the winding unit.

[0008] The beneficial effects of this utility model compared with the prior art are:

[0009] By modularizing the process, creating a three-dimensional space, and designing segmented composites, the system enables free switching between dry and solvent-free processes, efficient multilayer film composites, and a compact layout. This solves the problems of traditional production lines, such as single process, high energy consumption, and unstable quality, and is particularly suitable for the large-scale production of high-precision composite films.
