Turnover correction device
Function
The flip frame system is based on a simple principle:a round wheel is installed at 45° with the longitudinal axis and the transverse axis, and the contact radian with the material is 180°,which can immediately change the material direction of 90°.In order to guide the material at the same time,the roll wheel is installed on the plane parallel to the feeding surface.According to the signal generated,when the material is turning.Adjust material position.
Application
When using the overturning frame,there must always be a point-by-point force transfer between the overturning frame and the breadth.In order to protect the material surface,an air cushion can be used between the overturning frame and the breadth to reduce friction.In this way,the highest adjustment accuracy of (+1 mm) can be achieved.In order to improve the dynamic characteristics of regulation,besides the overturning frame,the collar should also be operated with the guide roll.The distance between the guide roll and the fixed roll should be half of the width of the breadth.Sensors must be installed directly behind the discharging roll as far as possible.
