Embodiment 1
[0038]The continuous coating production system of the TPU film includes a first unwinding unit 1 for unwinding the TPU base film. The TPU base film includes a TPU film and a protective film attached to the upper and lower surfaces of the TPU film; Leading unit, used to attach the leading film to the protective film on one side surface of the unwound TPU base film for connection; the first peeling unit 2, used to bond the other side surface of the TPU base film that is not connected with the leading film The protective film is peeled off; the coating unit 3 is used to coat the polymer on the surface of the TPU base film that has peeled off the protective film to form a coating layer; the drying unit 4 is used to complete the coating of the TPU base film by an oven The film is subjected to surface drying treatment; the UV curing unit 5 is used to perform ultraviolet curing treatment on the dried TPU base film through a UV lamp. This production system is suitable for the case whe...
Embodiment 2
[0040] The continuous coating production system of the TPU film includes a first unwinding unit 1 for unwinding the TPU base film. The TPU base film includes a TPU film and a protective film attached to the upper and lower surfaces of the TPU film; The introduction unit is used to connect the two sections of TPU base film on the same side of the two sections of TPU base film through the introduction film. The protective film is peeled off; the coating unit 3 is used to coat the polymer on the surface of the TPU base film that has peeled off the protective film to form a coating layer; the drying unit 4 is used to complete the coating of the TPU base film by an oven Carry out surface drying treatment; UV curing unit 5 is used to perform ultraviolet curing treatment on the dried TPU base film by UV lamp. This production system is suitable for the case where the product produced by coating on the first roll is TPU base film. When the first roll of TPU base film is unrolled, it ca...
