Abstract

The invention relates to a plastic detonating cord, in particular to an adjustable nose for a plastic detonating cord plastic coating and extruding machine. The adjustable nose comprises an extruding machine delivery rod, an electric heating ring, an extruding machine nose connecting sleeve, a thermocouple, a core mold fixing bolt, a core mold, an extruding machine mold body, a filter board, a gate mold adjusting bolt, a gate mold and a gate mold fixing bolt. Fixed connection of the extruding machine mold body and the gate mold of the plastic detonating cord plastic coating and extruding machine is changed to floating connection, the thickness of a plastic layer coated on an outer surface of a semi-finished detonating cord product penetrating through the core mold and the gate mold is even, thickness difference can be controlled from 0mm to 0.02mm and the product quality requirement for plastic detonating cord plastic coating is strictly guaranteed. The adjustable nose for the plastic detonating cord plastic coating and extruding machine is compact in structure, reliable in operation, convenient to use, automatic in coating, capable of reducing a failure rate, even in a coating layer, high in accuracy and capable of strictly guaranteeing product quality, remarkably improving economic benefit and being popularized and applied to all plastic detonating cord production enterprises and suitable for electric wire and electric cable production enterprises.

Description

technical field [0001] The invention relates to a plastic detonating cord, in particular to an adjustable head of a plastic detonating cord coating extruder. Background technique [0002] Plastic detonating cord production enterprises need to use extruders to coat a layer of plastic on the outer surface of the semi-finished detonating cord to complete the production task of plastic detonating cord. When entering the detonating cord plastic coating process, the coil of the detonating cord semi-finished product will be used as a pay-off wheel, and the detonating cord semi-finished product on the pay-off wheel will be pulled into the extruder mandrel and passed through the extruder mouth. The mold is pulled out, and when the plastic coating process starts, the extruder first turns on the power to melt the plastic, and when the temperature of the melted plastic reaches the set coating temperature, it is turned on again, and the extruder screw installed on the extruder will The ...
