Gluing die head for extruder

Abstract

The invention provides a gluing die head for an extruder, which ensures smooth surface of glued copper wires and higher product percent of pass. The technical scheme is as follows: the gluing die head comprises a copper wire inlet, an original glue injection port, a discharge sleeve and a gluing cavity. The inlet of the copper wire is positioned in the inner cavity of the central shaft, the original glue injection port is positioned in the inner cavity of a sheath, one end of the sheath is in inner thread connection with the central shaft, the other end of the sheath is in inner thread connection with the discharge sleeve, the cavity formed by the discharge sleeve, and the sheath and the central shaft is the gluing cavity which is characterized in that heating pipes are arranged around the original glue injection port of the sheath.

Description

technical field [0001] The invention relates to the technical field of copper wire outer circle gluing equipment, in particular to a gluing die for an extruder. Background technique [0002] Existing extruders use glue-coating dies, which include copper wire inlets and glue filling inlets. After the glue is mixed in the cavity, the glue is coated on the copper wires, and then the glue-coated copper wires go out from the outlet of the discharge sleeve. During the process of coating the glue on the copper wire, the temperature of the glue drops, resulting in poor fluidity, which in turn causes the surface of the glue-coated copper wire to be rough, and the qualified rate of the product decreases. Contents of the invention [0003] In view of the above problems, the present invention provides a gluing die for an extruder, which ensures a smooth surface of the gluing copper wire and a higher pass rate of the product. [0004] The glue coating die head for extruder, its techni...
