Example Embodiment

[0023] The content of the present invention will be further described below in conjunction with the accompanying drawings.

[0024] Such as Figure 1~3 As shown, the cooling device of a film stretching machine according to the present invention is used to cool and shape the film stretched by the forming cone roller 8, and is characterized in that: the cooling device includes arcs arranged in sequence. A cooling air grid 1, a first transmission drive mechanism 2, a cooling platform 3, and a second transmission drive mechanism 4. The first transmission drive mechanism 2 is used to pull the diaphragm to drive along the first cooling air grid 1, so The second transmission drive mechanism 4 is used for pulling the diaphragm to drive along the cooling platform 3, and the cooling platform 3 includes a cooling plate for supporting the diaphragm and a surface cooler arranged below the cooling plate.

[0025] Further, the first transmission drive mechanism 2 includes a first transmission ro...

Abstract

The invention relates to the technical field of cooling devices and particularly relates to a cooling device of a film-drawing machine for cooling and forming a film which is stretched by a forming conical roll. The cooling device is characterized by comprising a first cooling air grid, a first transmission driving mechanism, a cooling platform and a second transmission driving mechanism which are arranged in sequence in an arc shape, wherein the first transmission driving mechanism is used for pulling the film to transmit along the first cooling air grid, the second transmission driving mechanism is used for pulling the film to transmit along the cooling platform, and the cooling platform comprises a cooling plate for bearing the film and a surface cooler which is arranged below the cooling plate. The cooling device provided by the invention has the advantages of high forming precision and good transmission stability.

Description

Technical field: [0001] The invention relates to the technical field of cooling devices, in particular to a cooling device for a film stretching machine, which is especially suitable for cooling and forming stretched PVB diaphragms. Background technique: [0002] PVB is a commonly used intermediate film for laminated glass. It is a polymer material formed by plasticizing and extruding polyvinyl butyral resin with a plasticizer. It is a translucent film without impurities and has a smooth surface. Roughness and good flexibility, good adhesion to inorganic glass, transparency, heat resistance, cold resistance, humidity resistance, high mechanical strength, etc., is currently the best adhesive material for manufacturing interlayer and safety glass in the world , widely used in automotive laminated glass. [0003] Since there is a certain curvature in the automotive laminated glass, it is necessary to stretch the PVB to a certain curvature or thickness before bonding the PVB in...
