The Automatic Paint Roller Handle Machine is designed for the production of wire frames and their subsequent assembly together with plastic handles for paint rollers. The machine allows paint roller handles to be produced in various sizes and wire diameters.
The wire is taken off from a driven coil holder through twin-plane straightening rolls and into the feeding and length measuring system. The wire is fed and measured by two pairs of grooved rolls. Feed accuracy is ± 0.5 mm (0.02"). The cutting and forming of so called „wings“ for fixation of wire in handle are performed by a hydraulic device. The final shape of wire is bent by means of aservo motor, based on the method of free programmable step by step bending. Between two subsequent bending steps there always follows an accurate wire feeding. The programmable unit allows to change an angle and a length of feeding, driven by a servo motor, 3,5 kW, 4500 rpm. After bending follows transferring to the position for assembly together with the plastic handles. The machine runs in fully automatic cycle with production output approx. 17 – 19 handles per minute, depending of shape and length of handle type to be produced.
Changeover time different wire frame within the same wire diameter: 30 minutes.
Changeover time from between different wire diameter and wire frame: 4 hours.
