Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of silicone rubber production, and particularly relates to a film winding device. BACKGROUND

[0002] Silicone rubber products need to be processed into flat sheets of specific thickness and width by using a calender after mixing. In the calendering process, silicone rubber is heated and pressed by rollers. In the calendering process, silicone rubber is prone to sticking to the rollers due to temperature and pressure, and is difficult to separate. Therefore, a film is used as a separation layer to prevent the silicone rubber from directly contacting the rollers and reduce the possibility of sticking. After calendering, the silicone rubber sheets are usually stored in a stacked or wound manner. The film can isolate multiple sheets, facilitating storage, transportation, and processing. The weight of an industrial film roll is more than 50 kg. The existing film unwinding device relies on the cooperation of multiple people or the assistance of a forklift for winding. Due to the heavy weight of the film roll, installation is difficult, and improper operation can easily cause safety accidents.
