A film winding machine for reverse osmosis membrane processing

Abstract

This utility model relates to the field of film winding machine technology, specifically a film winding machine for reverse osmosis membrane processing: it includes a support frame, a first motor fixedly connected to the surface of the support frame, a take-up roller mounted on the output shaft of the first motor, and a constant pressure mechanism provided on the surface of the support frame, the constant pressure mechanism including a guide rail fixedly connected to the surface of the support frame. This utility model uses the output shaft of a second motor to drive a bidirectional lead screw to rotate. The bidirectional lead screw, through rotation, drives two sets of square nuts to slide on the surface of the support frame. During the sliding process, the square nuts drive a lifting plate to rise and fall via an adjusting rod. The lifting plate, during its sliding process, drives a lifting bracket and a pressure roller to rise and fall, thereby changing the pressure value of the pressure roller on the membrane material on the take-up roller. This ensures that the pressure roller always applies constant pressure to the membrane material on the take-up roller, ensuring that the membrane material is tightly wound on the take-up roller, reducing membrane roll slack and deformation, and improving the quality of winding.
