Abstract

The application belongs to the technical field of cable recycling, and particularly relates to a power cable ring cutting device, which comprises a power base, a pulling drum device arranged on the left side of the inner wall of the power base, a cutting device arranged on the right side of the inner wall of the pulling drum device, a rough cable arranged at the shaft center of the inner wall of the cutting device, and a limiting device arranged on the right side of the inner wall of the power base. The device performs ring cutting work on the rough cable through the sharp surface at the bottom of the sliding slice, then performs transverse cutting work on the outer skin of the rough cable through the sharp surface at the bottom of the steering cutting rod in the cutting groove generated by the ring cutting, and the cable skin is completely stripped from the cable core through the pushing action of the shaft center limiting ring. Since the sliding slice and the steering cutting rod only contact the outer surface of the cable when corresponding work is performed, the stress directions of the sharp surfaces of the sliding slice and the steering cutting rod are the same as the directions of the cutting edges, thereby effectively reducing the abrasion problem of the cutting edges and improving the service life of the cutting tools.

Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of cable recycling, and particularly relates to a power cable ring cutting device. BACKGROUND

[0002] A cable is an insulated wire composed of one or more mutually insulated conductive cores covered in a sealed sheath, which can be covered with a protective cover outside the sealed sheath, and is used for transmitting, distributing electric energy or transmitting electrical signals. The difference between the cable and the ordinary wire mainly lies in that the cable is larger in size and more complex in structure, and the cable is mainly used for control installation, connection equipment, power transmission and the like.

[0003] After old cables are recycled, the internal metal needs to be extracted, so the cables need to be ring cut to separate the outer sleeve and the internal cable core. However, when the existing ring cutting machine peels the long cable, the cable is first cut into a small section, and then the small section of the cable is cut and peeled. This causes the cutting tool to wear more severely, and the small section of the cable is easily mixed with the residual outer skin attached to the outer surface when collected, and further cleaning work is needed, which is very inconvenient and needs to be improved. SUMMARY

[0009] Further, the side of the inner sliding ring plate is slidably connected with the right side of the inner wall of the receiving cylinder shell through the reset spring, the number of the wire winding devices is two, the outer surface of the wire winding device is fixedly connected with the inner wall of the receiving cylinder shell, and the outer surface of the receiving cylinder shell is rotatably connected with a sliding transfer plate, the sliding transfer plate makes the receiving cylinder shell rotate around the rotation cutting groove on the outer surface of the sliding transfer plate through the internal rollers, so that the arc-shaped blade at the bottom end of the sliding slice can perform ring cutting processing on the outer surface of the thick cable, and the bottom end of the sliding transfer plate is slidably connected with the inner wall of the power base.

[0010] Further, the limiting device comprises a horizontal sliding box, the bottom end of the horizontal sliding box is fixedly connected with a height adjusting rod, the bottom end of the outer surface of the height adjusting rod is slidably connected with the inner wall of the power base through the rollers, and the top of the horizontal sliding box is provided with a wire clamping device. The horizontal sliding box comprises a slotted box shell, the bottom of the inner wall of the slotted box shell is fixedly connected with a pull plate inner box, the inner cavity of the pull plate inner box is symmetrically provided with a bent connecting plate on both sides, and the top end of the bent connecting plate is fixedly connected with a side pressure pull plate.

[0011] Further, the wire clamping device comprises a guide shaft, the outer surface of the guide shaft is symmetrically provided with a flexible connecting plate on both sides, one end of the flexible connecting plate away from the guide shaft is fixedly connected with a fixed hard shell, the side edges of the flexible connecting plates on the upper and lower sides can rotate around the guide shaft, so that the flexible connecting plates are deformed, the spacing between the fixed hard shells on the upper and lower sides is reduced, and the clamping force on the thick cable is increased, the inner walls of the fixed hard shells are uniformly provided with fixed motors, the outer surface of the output shaft of the fixed motor is fixedly connected with a friction concave wheel, and when the thick cable is pressed, the extrusion force of the friction concave wheels on the thick cable on the upper and lower sides is also increased.

[0012] Further, the outer surface of the flexible connecting plate is rotationally connected with the outer surface of the guide rotating shaft through a tangent slot, the outer surface of the friction concave wheel is pressed against the outer surface of the thick cable, the top of the side pressure pulling plate is rotationally connected with the upper part of the outer surface of the fixed hard shell, the top end of the bent connecting plate extends to the outside of the pulling plate inner box, and the top of the outer surface of the bent connecting plate is slidingly connected with the inner cavity of the slotted box shell through an external tangent sliding groove, and the outer surface of the fixed hard shell is fixedly connected with the shaft center of the upper surface of the slotted box shell.

[0013] The beneficial effects of the present application are as follows:

[0014] 1. The device first performs ring cutting work on the thick cable through the sharp surface of the sliding cutting piece bottom, then performs transverse cutting work on the outer skin of the thick cable through the sharp surface of the turning cutting rod bottom, and completely peels off the cable skin from the cable core through the pushing action of the shaft center limiting ring. Since the sliding cutting piece and the turning cutting rod only contact the outer surface of the cable when performing corresponding work, the stress direction of the sharp surface of the sliding cutting piece and the turning cutting rod is the same as the direction of the cutting edge, thereby effectively reducing the wear and tear of the cutting edge and prolonging the service life of the cutting tool.

[0015] 2. The device can cut the cable skin wrapped around the outer surface of the cable core into four strips, thereby effectively reducing the residual amount of the cable skin on the outer surface of the cable core. When the shaft center limiting ring slides from right to left, the resistance generated by the cable skin on the shaft center limiting ring is smaller, making the peeling work easier, and the resistance received by the storage cylinder shell is also smaller, thereby reducing the load of the power base and achieving the effect of easily peeling the cable skin.

[0016] 3. The device can perform cyclic cutting work on the whole thick cable, and completely peel off the cable skin on the outer surface of the cable. Since the peeled cable skin is pushed to the left by the inner sliding ring plate after each cutting, it is gathered in the left area of the storage cylinder shell, and the collection work of the cable skin is completed. Therefore, the internal cable core and the cable skin finally achieve the partition effect, avoiding the problem that the separated cable core and cable skin are mixed together, making the cleaning work more cumbersome and inconvenient.

[0017] 4. The limiting device of the device can not only push the external thick cable into the storage cylinder shell to achieve cyclic cutting work, but also fix the right side of the thick cable when the shaft center limiting ring slides from right to left, preventing the whole cable from being driven by the shaft center limiting ring to cause the problem of being unable to peel off the cable skin. Since the flexible connecting plate has a certain deformation capacity, the thick cable will not be cut off when it is fixed due to excessive extrusion force applied by the fixed hard shell, thereby ensuring that the long thick cable can be continuously processed in the device.
