Abstract
The utility model provides a device of low temperature lateral stretching PVDF film, is connected with cooling device including extrusion device and cooling device, extrusion device upper portion, and the extrusion device passes through pipe and cooling device interconnect, and cooling device is cooling air ring, the last deep bead that is equipped with of cooling device, deep bead upper portion is equipped with draw gear. Be equipped with the fixed stay part in that the haulage clip roller is other, can let the haulage clip roller tensile more stable in work, avoid the strength of haulage clip roller tensile inhomogeneous, influenced the quality of tensile PVDF film, in addition infrared heater's setting let the film heat in process of production evenly, avoided the quantity of heating part too high, guaranteed the film quality intensity height that the heating came out.
Description
Technical field
The utility model relates to a kind of stretching device, is specifically related to a kind of device of low temperature cross directional stretch PVDF thin film.
Background technology
PVDF mainly refers to the copolymer of a small amount of fluorine-containing vinyl monomer of Kynoar or vinylidene and other; there is good chemical resistance, heat-resisting quantity, oxidative resistance, weatherability, resistance to x radiation x performance; also there is the properties such as piezoelectricity, dielectricity, pyroelectricity, wearability, impact resistance, fade resistance and anti-ultraviolet property simultaneously, be widely used as the protective film of electronics, electric elements etc.
But the machinery of a lot of production PVDF thin film is in the process stretched, easily occur that stretching dynamics controls bad, the less effective of stretching, easily occur that oriented film occurs damaged, have impact on the quality of film.
Summary of the invention
It is simple that the purpose of this utility model is to provide a kind of structure, the device of the stable a kind of low temperature cross directional stretch PVDF thin film that stretches.The technical solution of the utility model is: a kind of device of low temperature cross directional stretch PVDF thin film, comprise pressurizing unit and cooling device, pressurizing unit top is connected with cooling device, pressurizing unit is interconnected by conduit and cooling device, cooling device is cooling vane, cooling device is provided with deep bead, and deep bead top is provided with draw-gear.
Described pressurizing unit is made up of extrusion die and conduit, is connected with air compression plant after extrusion die, and compressed air is transported in film bubble by extrusion die by air compression plant.
Described draw-gear is traction nip rolls and clamping plate, and clamping plate are mutually conflicted with traction nip rolls and are connected, and traction nip rolls is positioned at the top of clamping plate.
Described traction nip rolls is symmetrical structure, is provided with gap in the middle of traction nip rolls, and traction nip rolls is other is provided with fixed support part, and fixed support part is rectangular-shaped column.
Be provided with heater between described draw-gear and deep bead, be provided with infrared heater in heater, infrared heater is circular being distributed in heater.
The utility model has the advantages that: be provided with fixed support part on traction nip rolls side, traction nip rolls can be allowed when work to stretch more stable, avoid the agency pull drawing nip rolls uneven, have impact on the quality of stretching PVDF thin film, the setting of infrared heater is also had to allow film homogeneous heating in process of production, avoid add heat local too high, ensure that heating film quality intensity is out high.
