Abstract

A cutter head includes: a support platform; a double curved surface member mounted on the support platform and having a first curved surface and a second curved surface; a cutter wheel support member and a roller wheel support member moveably mounted on the support platform, respectively; a cutter wheel and a roller wheel mounted on the cutter wheel support member and the roller wheel support member, respectively; a first transmission mechanism mounted on the support platform, configured to be mated with the first curved surface, and connected to the cutter wheel support member, so as to transmit a movement of the double curved surface member to the cutter wheel; and a second transmission mechanism mounted on the support platform, configured to be mated with the second curved surface, and connected to the roller wheel support member, so as to transmit a movement of the double curved surface member to the roller wheel. The cutter head has a compact structure, and it improves the levelness of the cutter wheel and the roller wheel, and increases the mechanical precision.
