Description

Technical Field

[0001] The utility model relates to the technical field of PET sheet coating and drying, in particular to a PET sheet coating and drying device. Background Art

[0002] A PET sheet coating and drying device is a mechanical device specifically used for coating and drying PET (polyethylene terephthalate) sheets. This device is usually used in the plastic industry and packaging industry to improve the surface properties of PET sheets, increase adhesion, improve gloss, or endow them with other specific properties.

[0003] In the prior art, when most PET sheet coating and drying devices coat and dry sheets, they often use spray pipes and heating wires to coat and dry the sheets. However, the distance between the spray pipes and heating wires and the sheets in existing PET sheet coating and drying devices is relatively fixed. However, this design has some problems when dealing with sheets of different thicknesses or sizes. The fixed positions of the spray pipes and heating wires may cause the coating to not be evenly covered on the surface of the sheet, resulting in uneven coating thickness or too thin or too thick local coatings. In addition, the fixed position of the heating wires may also cause uneven distribution of heat energy on the surface of the sheet, with some areas overheating while other areas having insufficient heat energy, affecting the drying effect and the overall coating quality stability.

[0004] Therefore, those skilled in the art have provided a PET sheet coating and drying device to solve the problems raised in the above background art. Summary of the Utility Model
