Abstract

The invention relates to a PTFE high-strength film production device, which includes a stretcher and an uncoiling mechanism arranged at its feeding end. The stretcher includes a frame and an oven. Conveyor chain, the return end of the conveyor chain is outside the oven, and there are multiple cooling boxes outside the return end of the conveyor chain, each cooling box is connected with a suction pipe, the suction pipe is connected with a cooling fan, and the conveyor chain at the front end of the oven The outside of the process end is provided with a secondary cooling box, and the front and rear sides of the secondary cooling box are provided with blowing pipes facing the conveying chain, and the blowing pipes are connected with a blower. The present invention arranges the return end of the conveying chain on the expander outside the oven, and then cooperates with the cooling box arranged at the return end of the conveying chain to reduce the temperature of the conveying chain and improve the quality of product expansion through air suction.

Description

technical field [0001] The invention belongs to the technical field of film production, and in particular relates to a PTFE high-strength film production device. Background technique [0002] PTFE high-strength membrane is prepared by biaxial stretching method. It is used in the new energy industry to play the role of support and ion passage. The longitudinal tensile strength is greater than or equal to 220Mpa, the transverse tensile strength is greater than 20Mpa, and the porosity is about 85%. In the production process of PTFE high-strength membrane, it is necessary to stretch the short PTFE high-strength membrane in the oven to make PTFE high-strength membrane, but the current expander is to clamp the chain at both ends of the PTFE high-strength membrane from In and out of the oven, this causes the chain to stay in the oven for a long time. After a long time, the temperature of the chain will be much higher than the temperature required to stretch the PTFE high-strength f...
