Method and apparatus for measuring dynamic friction coefficient of rubber roller

摘要

The present invention relates to a method and an apparatus for measuring the friction coefficient of a rubber roller, comprising the steps of fixing the rubber roller to the main body of the rubber roller, fixing the test paper to the rubber roller provided on the front surface, Measuring the dynamic friction coefficient by reading the feed force indicator when the test paper is conveyed by rotation, and calculating the dynamic friction coefficient with the measured data, A frame fixed by hexagonal bolts on both sides of the shaft, a driving device provided on the frame, a rubber roller rotated by the driving device, and a transporting measurement of the lower body of the rubber roller A conveyance force indicator provided on the upper surface of the other end of the conveyance measurement table, a paper guide formed on one side of the conveyance force indicator, A pressing roller which is pressed against the rubber roller by the moving shaft which moves the pressing roller, a pressing roller which is pressed against the rubber roller, a pressing roller which presses the test roller against the rubber roller, The support portion and the hinge for supporting the support portion. Therefore, it is possible to accurately measure the dynamic friction coefficient of the roller by the rubber, so that the transfer of the printing paper can be carried out more smoothly in use.
