Core fixing type TPX coating machine head

Abstract

The utility model discloses a fixed core type TPX coating machine head, which relates to the technical field of coating machine heads, and comprises a machine head body part, a plurality of heating rods are annularly arranged in the machine head body part; a heating wire of the heating rod is hidden in the wire groove, and an inner cavity of the machine head body part is arranged in a conical shape. The machine head body part is heated by adopting the built-in heating rods, the heating rods are uniformly distributed and inserted into the machine head body part for heating, the machine head body part is uniformly heated, the heat dissipation area of the heating part is small, the heating efficiency is high, and the heating time of the machine head body part from a constant temperature to a set temperature is greatly shortened; meanwhile, a heating wire of the heating rod is hidden and fixed in the wire groove and is sealed and fixed through the end cover, the problem of exposure of the heating wire is avoided, the heating rod is internally heated, the exterior of the machine head body part is not oxidized, the machine head body part is good in appearance for a long time, meanwhile, the influence of an external wire and a heating ring is avoided, and the machine head body part can be conveniently disassembled and cleaned.
