Description
Technical field
The invention belongs to polytetrafluoroethylene (PTFE) production fields, more particularly, to a kind of winder with gravity tension device
Structure.
Background technique
PTFE turning film is to be cold-pressed through PTFE resin, be sintered turning again and form, the attractive interaction between PTFE macromolecular compared with
Small, rigidity, hardness, intensity are all smaller, and turning film passes through multiple deflector rolls in wrapup procedure and winds under tension,
Guarantee winding after film surface it is smooth, tension it is steady critically important.But PTFE Film stiffness and hardness are all smaller, such as overtension meeting
It causes film surface after winding to have " packet muscle " phenomenon, " packet muscle " situation is eliminated as tension is too small, but winding is insecure, is easy de-
It falls.Again since the blank for turning is to be cold-pressed, be sintered, the pressure that each position of blank is subject in cold pressure procedure is not
It is identical.There is no assurance that the consistency of density, the height of blank Contact Temperature and time can not during the sintering process
It is completely the same, so the inhomogeneities of density caused by can not making up in pressing process, so in turning wrapup procedure by
The effect of same tension, film surface is also different by the reaction of power, equally will cause " packet muscle " phenomenon.
