THICKNESS FIXING APPARATUS FOR CONTINUOUS FOAM MATERIAL

WIPO Patent Application WO/2021/258609

A1

A thickness fixing apparatus for a continuous foam material, relating to the technical filed of foam material production devices. The thickness fixing apparatus comprises a foaming cavity (1) and a thickness locking portion (2). The two ends of the foaming cavity (1) are respectively provided with a material inlet (11) and a material outlet (12); several heating elements (13) are provided on the inner wall of the foaming cavity (1) along a foam material conveying direction; the thickness locking portion (2) is provided outside the material outlet (12); the thickness locking portion (2) comprises a pressure roller (21) and a deflecting roller (22) provided opposite to each other and communicated with a cooling medium pipeline; a cooling structure (23) is provided on the surface of at least one of the pressure roller (21) and the deflecting roller (22), and at least one of the pressure roller (21) and the deflecting roller (22) is a driving roller driven by a power device to rotate; the foam material passes through a pressing area between the pressure roller (21) and the deflecting roller (22) and then is conveyed out in a manner of being attached to the surface of the deflecting roller (22). The present invention can achieve precise and fast foam material thickness fixing, and effectively reduce the dimensional deviation of a finished product, thereby improving the quality of the finished product.
