Coating roller constant-temperature heating device for coating machine

Abstract

The invention discloses a coating roller constant-temperature heating device for a coating machine, and belongs to the technical field of coating machine equipment. The roller shaft is coaxially connected in the roller body; the two ends of the roller shaft are fixedly sleeved with the packing discs in a bilateral symmetry mode, and bearings are installed on the roller shaft and located on one sides of the two packing discs; the fixed terminals are fixed at the two end parts of the roller body and are positioned on the other side of the bearing; the transmission gear is arranged on one of the fixed terminals in a sleeving manner; the center of the liquid storage cavity is formed in the roll shaft, and heat conduction oil is distributed in the liquid storage cavity in a flowing mode; the heating device is installed in the liquid storage cavity, and the heating device heats the heat conduction oil in an electric heating mode; the plurality of liquid guide units are arranged and distributed, and the liquid guide units are uniformly distributed in the roller body and are positioned outside the roller shaft; according to the invention, heated heat-conducting oil can circularly flow and diffuse in the roller body through the liquid guide unit, so that the heating uniformity is improved.
