Description

TECHNICAL FIELD

[0001] The utility model relates to the preheating device field for the covering of the multiple strand twisted enameled wire core, more specifically, to a preheating device for the covering of the multiple strand twisted enameled wire core. BACKGROUND

[0002] In the process of covering the multiple strand twisted enameled wire core, the plastic covering material is heated and then extruded to the outer layer of the wire core by an injection molding machine for covering. The covering of the wire core is mainly used for protecting the wire core and providing an insulating environment for the wire core. However, when the wire core is directly covered, the covering material cannot be well adhered to the wire core due to the low temperature of the wire core. Therefore, in order to improve the covering effect, the wire core needs to be preheated before covering to improve the covering effect of the wire core.

[0003] In the conventional technology, for example, in the Chinese patent with the publication number CN214624553U, a cable core preheating device is disclosed, which includes a hot air blower, a support frame and a heating sleeve. The cable core movably penetrates the heating sleeve, the heating sleeve is fixed to the upper end of the support frame, and the outer wall of the heating sleeve is connected in communication with the hot air blower through a heating air pipe.
