Abstract

The invention relates to the technical field of film drawing equipment, especially to a conical roller assembly for shaping by a film drawing machine. A first rotating shaft is rotatably mounted on a frame; a first rotating disk is fixedly arranged on the first rotating shaft; a second rotating disk is slidably installed on the first rotating shaft; a crank link mechanism comprises a crank and a connecting rod, wherein one end of the crank is hinged with the second rotating disk through a second hinge joint while the other end of the crank is hinged with the body of the connecting rod through a third hinge joint, the front end of the connecting rod is hinged with the first rotating disk through a first hinge joint, and the crank, the connecting rod and the first rotating shaft are located in a same plane; the number of the crank link mechanisms is 45 to 75 groups, and the crank link mechanisms are of a same size and shape and are uniformly distributed in the shape of a ring array with the first rotating shaft as a center; and the external surfaces of the connecting rods form a conical surface with the first rotating shaft as an axial center through enclosure. The conical roller assembly has the advantages of stationary motion, high accuracy and rapid and simple adjusting, so product quality and production efficiency are improved.

Description

Technical field: [0001] The invention relates to the technical field of film-drawing equipment, in particular to a tapered roller assembly for forming a film-drawing machine, which is used for stretching an interlayer film for laminated glass, and is especially suitable for stretching PVB. 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 ...
