s2, introducing the pultruded product woven with the fiber layer into a resin material for gum dipping treatment;
s3, the dipped pultrusion product enters a pultrusion mould for heating and curing molding;
s4, detecting the outer surface of the pultrusion product formed through curing through an automatic detection device, if the outer surface of the pultrusion product is smooth and has no pits or scratches, entering S6, and if the outer surface of the pultrusion product has pits or scratches, entering the next step S5;
s5, sleeving a cleaning sleeve on the pultrusion product before curing molding, wherein the pultrusion product drives the cleaning sleeve to pass through the interior of the pultrusion mold, the cleaning sleeve brings out the residual resin on the inner wall of the pultrusion mold, and when the cleaning sleeve passes through the mold, S4 is executed;
and S6, cutting the blank into a finished product according to the required length.
10. The pultrusion production process as claimed in claim 9, characterized in that: automatic checkout device is including detecting camera, treater and alarm, process pultrusion mould pultrusion product is in detect the shooting within range of camera, at least two detect the camera encircle pultrusion product periphery, detect the camera with the alarm all with treater electric connection, detect the camera and regularly shoot the photo of pultrusion product, the photo conveys the treater, the treater is handled the back with the photo, judges whether the surface of pultrusion product meets the requirements, if not meet the requirements, the treater arrives signal transmission the alarm, the alarm starts the warning.
