Nondestructive marking device for cable insulation spark breakdown point

Abstract

The invention discloses a nondestructive marking device for a cable insulation spark breakdown point. The nondestructive marking device comprises a base, wherein the top center of the base is fixedlyconnected with a lifting mechanism; the top of the lifting mechanism is fixedly connected with a mounting case; the inner bottom of the mounting case is fixedly connected with a servo motor; the tailend of an output shaft of the servo motor is fixedly connected with a first bevel gear; the inner bottom of the mounting case is rotationally connected with a first rotating rod which is arranged in the vertical direction; a side wall of the first rotating rod is fixedly sleeved with a second bevel gear; the second bevel gear is meshed with the first bevel gear; the top of the first rotating rod is fixedly connected with a reciprocating screw; the top of the reciprocating screw is fixedly connected with a second rotating rod; and one end, far away from the reciprocating screw, of the second rotating rod is rotationally connected with the inner top of the mounting case. The nondestructive marking device is convenient to operate; and bristles are driven to mark a cable by using the servo motor to achieve the targets of reducing noise of the nondestructive marking device for the cable insulation spark breakdown point and reducing air pollution of a spray paint.

Description

technical field [0001] The invention relates to the technical field of cable production equipment, in particular to a non-destructive marking device for spark breakdown points of cable insulation. Background technique [0002] In the production process of wire and cable, in order to ensure the quality of the cable insulation layer, it is necessary to use a spark machine to detect the spark breakdown of the cable insulation layer, and mark the breakdown point during the detection process, so that sparks can be found in time in the subsequent process Break down the point and deal with it. There is no special equipment on the market for marking the spark breakdown point of the insulation layer. In the production process, a full-time marking personnel is required to mark the outer surface of the cable insulation layer according to the alarm prompt of the spark machine. Paste colored tape on the insulating layer near the piercing point. Since the cable is constantly moving durin...
