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] PET material, namely polyethylene terephthalate, is a widely used plastic material with excellent physical and chemical properties, such as high strength, good wear resistance, and chemical corrosion resistance. PET material is non-toxic, impermeable, light weight, and has high production efficiency. It is widely used to make packaging containers such as mineral water bottles and carbonated beverage bottles. At the same time, it is also used to manufacture various types of food, medicine, and non-toxic and sterile packaging materials. Coating and drying equipment is required when processing PET sheets.

[0003] In the prior art, such as publication number: CN220532094U, a PET sheet coating and drying equipment is disclosed, which includes a mounting platform 1 and a mounting platform 2, wherein a rotating shaft 1 is installed on one side of one end of the mounting platform 1, a coil spring is installed on the surface of the rotating shaft 1, a loading roller is sleeved on the surface of the coil spring, a PET sheet is installed on the surface of the loading roller, and an end of the rotating shaft 1 away from the mounting platform 1 is connected to one side of one end of the mounting platform 2; the utility model installs a coil spring on the surface of the rotating shaft 1 so that the loading roller maintains a rotational force when the winding roller winds the PET sheet, thereby tensioning the surface of the PET sheet and reducing the generation of wrinkles on the surface of the PET sheet.

[0004] However, the device still has some problems. For example, a coil spring is installed on the surface of a rotating shaft so that the feeding roller maintains a rotational force when the winding roller winds the PET sheet, thereby tensioning the surface of the PET sheet and reducing the generation of wrinkles on the surface of the PET sheet. However, in actual use, the sizes of the PET sheets to be processed each time are different. Some PET sheets with a smaller width may be skewed on the mounting table during transportation due to a simple connection through a feeding roller during processing, resulting in a skewed coating pattern and reduced processing quality. Therefore, we disclose a PET sheet coating and drying device to meet people's needs. Utility Model Content
