At this time, the silicone oil enters the hollow coating roller through the inner cavity of the oil collecting cylinder, and then is discharged to the oil absorption sleeve pad through the oil outlet hole. Under the action of the winding mechanism, the upper hollow coating roller and the lower hollow coating roller rotate in the inner cavity of the movable hole, and silicone oil is applied to both sides of the PET sheet at the same time, and the coating is very uniform, so as to facilitate the simultaneous coating of silicone oil on both sides of the PET sheet, and the coating is very uniform, thereby ensuring the uniformity of silicone oil coating on the entire PET sheet.

[0019] 2. The PET sheet silicon coating device provides electric energy to the heating rod through an external power supply. At this time, the current is introduced into the electric heating element through the wire, and the electric heating element generates heat to heat the sleeve. Finally, the high-temperature radiation effect of the stainless steel tube surface transfers the heat to the silicone oil coated on the surface of the PET sheet, thereby facilitating the drying of the PET sheet coated with silicone oil.
