[0034] Application method of this utility model:
[0035] Application Example 1: Differential Coating + Gravure Screen Coating
[0036] like Figure 2 As shown, the roll of film to be processed is unwound by the first unwinder 2 and enters the first coating machine 1 for differential coating and is output from the outlet. It then enters the first drying oven 9 through the first transport roller 11, and then enters the upper drying tunnel of the second drying oven 8. It is then transported by the first layer roller of the upper drying tunnel, and then enters the second drying oven 8 in sequence through the fourth transport roller 14 and the fifth transport roller 15. It is then transported by the second layer roller of the upper drying tunnel, and then enters the second coating machine 3 in sequence through the second transport roller 12 and the eighth transport roller 18 for gravure coating and is output from the outlet. Then, it enters the lower drying tunnel of the second drying oven 8 in sequence through the seventh transport roller 17 and the third transport roller 13. After coating and drying, the coated film enters the winding machine 5 for winding through the sixth transport roller 16 and the ninth transport roller 19.
[0037] Application Example 2: Gravure Screen Coating
[0038] like Figure 3 As shown, the roll of film to be processed is unwound by the second unwinder 4 and enters the second coating machine 3 for gravure coating. It is then output from the outlet and enters the lower drying tunnel of the second drying oven 8 through the seventh transport roller 17 and the third transport roller 13 in sequence. After coating and drying, the roll of film is fed into the ninth transport roller 19 through the sixth transport roller 16 and finally enters the rewinder 5 for rewinding.
[0039] Application Example 3: Gravure Halftone Composite
[0040] like Figure 3 As shown, the roll of film to be processed is unwound by the second unwinder 4 and fed into the second coating machine 3 for gravure coating. It is then output from the outlet and sequentially passes through the seventh transport roller 17 and the third transport roller 13 into the lower drying tunnel of the second drying oven 8. After coating and drying, the roll of film is fed into the third coating machine 6 via the sixth transport roller 16. Simultaneously, the roll of film output from the third unwinder 7 passes through the roller conveyor structure of the third coating machine 6 (only the roller conveyor function within the third coating machine 6 is used, not its coating function). Finally, both rolls of film are fed into the rewinder 5 via the ninth transport roller 19 for winding, resulting in a composite film.
[0041] Application Example 4: Composite of Slot Coated Roll Film
[0042] like Figure 4As shown, the roll of film to be processed is unwound by the second unwinder 4, passes through the roller conveyor structure within the second coating machine 3 (only the roller conveyor function of the second coating machine 3 is used, not its coating function), and then sequentially passes through the seventh transport roller 17 and the third transport roller 13 into the lower drying tunnel of the second drying oven 8. After drying, the roll of film is fed into the third coating machine 6 via the sixth transport roller 16. At the same time, the roll of film output from the third unwinder 7 passes through the third coating machine 6. The two rolls of film are combined and laminated by slot coating in the third coating machine 6, and finally enter the rewinder 5 via the ninth transport roller 19 for winding to obtain a composite film.
[0043] This invention enables multi-functionality, replacing traditional large-scale coating and laminating equipment. Specifically, it can replace the functions of five machines: a differential speed coating machine, a gravure linear roller coating machine (Application Example 2), a gravure linear roller dry laminating machine (Application Example 3), a one-time differential speed + gravure linear roller double-layer coating machine (Application Example 1), and a slot coating laminating machine (Application Example 4). It allows for flexible selection of coating machines to meet the requirements of different coating processes for different paints. In particular, the double-layer coating structure design can meet the requirements of one-time superposition coating of different paints and different die heads. Furthermore, it allows for the selection of individual functions of several coating die heads, which can be switched arbitrarily without interference. The multi-segment double-layer drying tunnel design can meet the coating process requirements of each die head. The entire equipment saves on equipment costs and space usage while improving efficiency.
