In the rotary peeler for the cable of the embodiment, due to the arrangement of the cable passing port of the shaft sleeve, the cable passing port of the gear and the cable passing port of the shell, when in specific use,
firstly, an operator holds an insulating holding rod by hand, a driving gear and a driven gear are driven to rotate through a gear driving motor, so that a cable passing port of a shaft sleeve and a cable passing port of a gear are aligned with a cable passing port of a casing, then the gear driving motor stops working, the operator holds the insulating holding rod by hand, so that an overhead cable moves into a rotating shaft sleeve through the cable passing port of the casing, the cable passing port of the gear and the cable passing port of the shaft sleeve, and the overhead cable is positioned between two cable holding claws;
secondly, the screw rod driving motor works to drive the driving screw rod to rotate, and the driving screw rod drives the two cable holding claws to approach each other to hold the aerial cable (slightly hold the aerial cable) due to the fact that the spiral directions of the two sections of thread sections are opposite, at the moment, the aerial cable is approximately coaxial with the axis of the rotating shaft sleeve, the tool nose and a part of the tool nose of the rotary cutting blade cut into an insulating layer of the cable, and the tool nose and a part of the tool nose of the circular cutting blade also cut into the insulating layer of the cable;
thirdly, as shown in fig. 5, the gear driving motor is controlled to rotate forward, the driven gear, the rotating shaft sleeve, the rotary cutting assembly and the circular cutting assembly are driven by the driving gear to rotate clockwise for 360 degrees, in the process, the insulating layer of the cable acts on the circular cutting blade, the circular cutting blade is driven to be tightly pressed on the first limiting part, so that the circular cutting blade cuts the insulating layer of the cable, and the circular cutting blade is perpendicular to the rotating shaft of the rotating machine base, so that the insulating layer of the overhead cable is cut by the circular cutting blade in a circular shape after the circular cutting blade rotates for 360 degrees (the cutting track of the circular cutting blade on the insulating layer of the overhead cable is a circular ring); meanwhile, in the process, the action force of the insulating layer of the cable on the rotary-cut blade drives the rotary-cut blade to be separated from the second limiting piece, the tool nose of the rotary-cut blade is pressed against the surface of the insulating layer of the cable under the action of the second torsion spring and rotates around the cable, and the rotary-cut blade does not cut the insulating layer of the cable in the clockwise rotating process; therefore, in the process that the gear driving motor drives the rotating shaft sleeve, the rotary cutting assembly and the circular cutting assembly to rotate clockwise by 360 degrees, on one hand, the rotary cutting blade does not cut the insulating layer of the cable, and the circular cutting blade cuts the insulating layer of the overhead cable in an annular mode; on the other hand, when the rotary cutter blade and the ring cutter blade simultaneously cut the insulating layer of the cable, the ring cutter blade can be prevented from blocking the rotary peeler for the cable to move along the axial direction of the overhead cable, so that the rotary cutter blade can not smoothly and spirally cut the insulating layer of the overhead cable along the axial direction of the overhead cable (because the cutting track of the rotary cutter blade on the insulating layer of the overhead cable spirally extends along the axial direction of the overhead cable and drives the whole rotary peeler for the cable to move along the axial direction of the overhead cable);
fourthly, as shown in fig. 5, the gear driving motor is controlled to rotate reversely, the driven gear, the rotating shaft sleeve, the rotary cutting assembly and the circular cutting assembly are driven to rotate clockwise and reversely through the driving gear, in the process, the insulating layer of the cable acts on the circular cutting blade, the circular cutting blade is driven to be separated from the first limiting piece, the tool nose of the circular cutting blade abuts against the surface of the insulating layer of the cable under the action of the first torsion spring and rotates around the cable, and the circular cutting blade does not cut the insulating layer of the cable in the counterclockwise rotating process; meanwhile, in the process, the rotary-cut blade is driven to be tightly pressed on the second limiting piece by the acting force of the insulating layer of the cable on the rotary-cut blade, so that the rotary-cut blade cuts the insulating layer of the cable, and because the included angle between the rotary-cut blade and the rotating shaft of the rotary machine base is 80 degrees, the cutting track of the rotary-cut blade on the insulating layer of the overhead cable spirally extends along the axial direction of the overhead cable, and the whole cable is driven to move along the axial direction of the overhead cable by the rotary peeler; so, because this in-process, the ring cutter piece is at the anticlockwise rotation in-process not cutting the insulating layer of cable, therefore the ring cutter piece can not block the axial displacement of rotary type peeler for the cable along aerial [ insulated ] cable, guarantees the axial displacement of rotary type peeler for the cable along aerial [ insulated ] cable, and the axial spiral cutting aerial [ insulated ] cable of edge aerial [ insulated ] cable that makes rotary-cut blade can be smooth.
