Description

Technical Field

[0001] The present invention relates to the technical field of lead stripping, and in particular to a device and method for stripping a power lead. Background Art

[0002] The power lead is an existing component used in the prior art to transmit electric energy, which is also known as the cable. In the actual production process of the power lead, it is usually composed of multiple conductors. The surface of each metal conductor will be extruded or vulcanized to form an insulating plastic layer, rubber layer or PVC lining as the insulating layer of the conductor. However, in the actual production and matching process of the power lead, in the subsequent production and cabling process, multiple conductors will be twisted into a complete power lead. However, in the process of insulating the surface of a single conductor, it is inevitable that there will be problems such as the thickness of the extruded insulating layer and the outer diameter of the conductor not meeting the standards during actual production, or the surface insulation layer of some produced conductor stock lines needs to be replaced. In this case, the original insulating layer on the surface of the conductor needs to be stripped off, and at this time a special lead stripping device is needed to strip the lead.

[0003] In the actual process of stripping the power leads, sometimes the lead needs to be stripped for a long length, so the peeled skin will accumulate on both sides of the stripping device, making the strip skin mixed together.

[0014] A method for stripping a power lead, using the above-mentioned power lead stripping device, comprises the following steps:

[0015] Step 1, unwinding the power lead: installing a holding shaft with the power lead wound on the unwinding device, and also installing a holding shaft on the winding device, so that one end of the power lead is moved through the conveying device into the installation chamber under the action of the winding device and the traction rope installed on the traction device, so that the power lead is located between the plurality of traction wheels and the clamping wheel;

[0016] Step 2, adjusting the position of the flip frame: starting the first electric cylinder to drive the rotating shaft to move, so that the flip frame moves along the center point of the rotating seat, and the flip frame flips downward, so that the two longitudinally corresponding stripping wheels are in contact with the upper and bottom of the power lead respectively;

[0017] Step 3, peeling: starting the first driving motor to drive the rotating shaft and the peeling wheel to rotate, so that the peeling wheel splits the skin on the surface of the power lead into two halves, and the two peeled skins are moved into the traction chamber respectively, and the exposed metal conductor is moved to the winding device through the traction of the traction rope and the traction device, and finally wound onto the containing shaft of the winding device;

[0018] Step 4, adjusting the positions of the plurality of arc-shaped retracting plates: starting the second electric cylinder to drive the connecting plate to move, so that the connecting rod moves within the rotating cylinder, and during the movement of the connecting rod, the plurality of sliding blocks will be driven to slide in the corresponding slope-shaped slide grooves, so as to adjust the deployment area between the plurality of arc-shaped retracting plates;

[0019] Step 5, adjusting the position of the installation slot: starting the second drive motor to drive the bidirectional screw to rotate, thereby adjusting the distance between the two lifting frames in the sliding frame, so that one side of the plurality of arc-shaped retracting plates enters the annular groove, and then starting the third drive motor to drive the lifting screw to rotate, thereby adjusting the height of the installation slot in the lifting frame;

[0020] Step 6, conveying the epidermis: cutting the first section of the epidermis into the traction chamber, so that the first section of the epidermis is divided into two, and the two sections of the epidermis pass through the upper and lower sides of the splitting saw blade respectively, and the epidermis passes through the corresponding fixing ring sleeve, so that one end of the epidermis is fixed between the multiple arc-shaped retracting plates, and then the two mounting disks are driven to rotate by the rotating drive assembly, so that the mounting disk drives the multiple arc-shaped retracting plates to retract the epidermis;

[0021] Step 7, clamping the epidermis: by making the two sliding grooves slide in the sliding member, the two clamping wheels clamp the epidermis, so that the epidermis that has been initially cut is spread out as much as possible, and then adjusting the positions of the arc-shaped extrusion member and the concave extrusion member in the traction chamber, so that the arc-shaped extrusion member and the concave extrusion member limit the position of the epidermis during the movement;

[0022] Step 8, secondary cutting: after the skin passes through the cutting range of the splitting saw blade, the splitting saw blade is rotated to perform secondary cutting on the skin;

[0023] Step nine, arranging the epidermis, when the epidermis is rolled up during the rotation of the plurality of arc-shaped rolling plates, starting the fourth driving motor to drive the transmission screw to rotate, so that the transmission screw drives the fixing frame to move laterally, so that the epidermis moves with the fixing frame and the fixing ring, so that the epidermis is evenly arranged on the arc-shaped rolling plates;

[0024] Step 10, tying the skin: after the skin is rolled up, the distance between the two lifting frames is adjusted by the bidirectional screw to make the two lifting frames move away from each other, and then a cable tie is inserted between two adjacent arc-shaped rolling plates to tie the skin bundle;

[0025] Step 11, remove the epidermis: after the epidermis is bundled, start the second electric cylinder to drive the connecting rod to move, so that the sliding block moves in the slope-shaped slide groove, thereby adjusting the position of the multiple arc-shaped retracting plates, so that a gap appears between the bundled epidermis and the arc-shaped retracting plates, and the epidermis is bundled between the multiple arc-shaped retracting plates and removed.

[0026] The working principle and beneficial effects of the present invention are:

[0027] 1. In the present invention, when it is necessary to perform a stripping operation on a single conductor in a power lead, firstly, a holding shaft for winding up the lead is fixed on a unwinding device, so that the lead passes through a conveying device, an installation chamber and a traction device in sequence, so that the metal conductor is finally wound up by the cooperation of the winding device and the holding shaft, and after the separation operation of the two stripping wheels, the upper and lower sides of the epidermis are cut, so that the epidermis is divided into two halves, and then the two halves of the epidermis are respectively moved into two traction chambers, and the epidermis is restricted during the movement by a moving adjustment mechanism, so that the epidermis is further divided into two halves after being cut by a splitting saw blade. Because the initially peeled epidermis is in a U-shape, if the epidermis is rolled up at this time, the epidermis will occupy a large winding space and is prone to clutter during the winding process, and if the epidermis is split twice, a single epidermis can be split into a tile-like shape, so that the epidermis is easier to be rolled up, and the rolled epidermis bundle is more compact and stable;

[0028] Therefore, in actual use, the power lead stripping device can roll up the peeled skin after stripping the lead surface, and during the rolling process, the skin can be cut a second time to reduce the volume of the entire skin and make the skin bundle more stable after rolling, which is convenient for subsequent recycling of the skin.
