Casting roller device and coating machine

Abstract

The utility model relates to the technical field of coating machines, in particular to a casting roller device and a coating machine. The two groups of bearing assemblies are arranged on the frame body at intervals; each group of bearing assembly comprises a bearing and a bearing seat; the bearing seat is arranged on the frame body, and a mounting hole for mounting a bearing is formed in the bearing seat; the bearing is mounted in the mounting hole and is in interference fit with the mounting hole; rotating shafts are coaxially arranged at the two ends of the casting roller body, the two rotating shafts are arranged in the two bearings in a penetrating mode correspondingly, and the rotating shafts are in interference fit with the bearings; the driving assembly comprises a servo motor and a speed reducer; the speed reducer is arranged on the frame body, and the output end of the speed reducer is in driving connection with the casting roller body; the servo motor is connected with the speed reducer, and the output end of the servo motor is in driving connection with the input end of the speed reducer; the technical problem that a produced base film has the quality problem due to the fact that the rotation tolerance of a casting roller in an existing coating machine is large in the rotation process is solved.
