The invention discloses a graphite layer evenly-brushing device for a high-voltage cable. The device comprises a rotation drum; the wire entering end of the rotation drum is circumferentially connected with a plurality of supporting rods through bolts; the central axes of the supporting rods are perpendicular to the central axis of the rotation drum; the end portions of the supporting rods are rotationally provided with roller brushes; a curved groove is arranged in the outer wall of the rotation drum; a hollow air pipe is arranged below the rotation cylinder; the air pipe is provided with anair inlet and an air outlet; the air inlet is connected with an air blowing pump through a pipeline; the air outlet is connected with an air extracting pump through a pipeline; a jacking rod is fixedonto the air pipe; the upper end of the jacking rod abuts against two side walls of the curved groove; the jacking rod is provided with a first conductive block and a second conductive block; the first conductive block and the second conductive block are connected with each other through a wire; a hollow traction rod is fixedly connected to the air pipe; a mounting disk is arranged on the top of the traction rod; the disk outer wall and disk inner wall of the mounting disk form a cavity; and a plurality of suction cups which are communicated with the cavity are evenly arranged on the disk inner wall. With the technical schemes of the invention adopted, evenly brushing treatment can be performed on the graphite layer of the high-voltage cable, so that a uniform graphite layer can be obtained.

The present invention relates to the technical field of composite board production, in particular to a hydraulic device for composite board production, including a bottom plate and a connecting frame, and the inner side of the bottom end of the bottom plate is fixedly connected with a limiting device, and the limiting device includes a first motor, a second A bevel gear, a second bevel gear, a first lead screw, a first slider, a fixed block, a push rod, a connecting plate, a push plate, a limit rod, a first spring and a stop plate, and the inside of the bottom end of the bottom plate is fixed A first motor is connected, and the main shaft end of the first motor is fixedly connected with a first bevel gear. The push plate, the limit rod and the stop plate, through the action of the first lead screw, the left and right push plates can clamp and fix the raw material at the same time, so as to ensure that the raw material will not be deflected during the pressing process, and at the same time, through the first spring The push plate can be slowly contacted with the raw material to prevent the push plate from causing instantaneous extrusion of the raw material.
