Abstract

The invention discloses a cooling roller in the technical field of film production equipment. The cooling roller comprises a guide roller; a cavity is formed in the guide roller; one end of the guide roller is connected with a first flange, and the other end of the guide roller is connected with a second flange; a first bearing is fixedly arranged on the first flange; a second bearing is fixedly arranged on the second flange; multiple annular cooling pipes are arranged in the cavity in sequence; the cooling pipes and the guide roller are coaxial; the outer walls of the cooling pipes cling to the inner wall of the guide roller; water inlets and water outlets are formed in the walls of the cooling pipes, and are symmetrically arranged; a water inlet pipe and a water outlet pipe which are coaxial with the guide roller are arranged in the cavity; a first connecting pipe communicates between the water inlets and the water inlet pipe; a second connecting pipe communicates between the water outlets and the water outlet pipe; the water inlet pipe is rotationally connected with the first bearing; and the water outlet pipe is rotationally connected with the second bearing. The multiple annular cooling pipes respectively cool own areas clinging to the inner wall of the guide roller; and the guide roller is uniformly cooled to facilitate molding of thermoplastic films.

Description

technical field [0001] The invention relates to the technical field of film production equipment, in particular to a cooling roll. Background technique [0002] Thermoplastic film, also known as thermoplastic film, is a film made of thermoplastic resin as the base material. Such as polyethylene film, polypropylene film, polyvinyl chloride film, polystyrene film, polycool film, polyamide film, etc. Its properties and uses vary with varieties. The largest amount of polyethylene film and polyvinyl chloride film is mainly used in packaging industry and agriculture; polycool film and polyamide film are mainly used as insulating materials and packaging materials. [0003] In the production method of thermoplastic film, after the thermoplastic resin is melted at high temperature, it is cooled and shaped by a cooling roll to prevent the quality of the finished product from being affected by cold shrinkage after winding. One end of the roll flows to the other end, and in this proc...
