Description
Technical Field
The invention relates to the technical field of cable stripping and recycling, in particular to a cable stripping device and a stripping method.
Background
The cable has very wide application in various fields of production and construction. The cable comprises a plurality of wires, an insulating sheath and a protective sheath, wherein a plurality of wire harnesses with the same or different functions are simultaneously wrapped in the insulating sheath, the protective sheath is wrapped outside the insulating sheath, and then the filler is filled in the middle of each wire harness, so that a cable is formed; some cables also have an armor layer between the insulating jacket and the protective sheath to strengthen the cable's outer jacket strength.
The cable must be problematic during long-term use and become a waste product. In order to recycle valuable materials in a cable, a wire harness in a good state in the cable is recycled, the cable is peeled by a peeler, and the wire harness in the cable is taken out by peeling an insulating sheath, a protective sheath and armor serving as an outer layer of the cable. The types of cable stripping machines on the market are various, and the stripping machine can be suitable for stripping cables with various sizes.
Most of the harnesses in the cable are parallel. Chinese patent CN110783026a discloses an insulated wire and cable in which the wire harness is spirally wound, i.e. twisted together as shown in fig. 1, rather than the usual parallel wire harness. Such cables are commonly referred to in the industry as twisted-wire cables, the types of which include twisted-pair, three-twisted-wire, four-twisted-wire, five-twisted-wire, and the like; meanwhile, there are cases where the diameters of the respective wire harnesses spirally wound with each other are not the same.
When a cable is stripped by a cable stripper, a cutter of the cable stripper moves along the axial direction of the cable, and in order to cut the outer layer of the cable and expose and separate a plurality of wire bundles therein from each other, the depth of the cutter needs to be capable of cutting an insulating sheath and filling between a plurality of wires. For the parallel cables of the internal wire harnesses, the cutter can not damage the wire harnesses in the parallel cables when cutting along the cables. However, when the twisted wire cable is peeled, because the wire harnesses are twisted and wound together instead of being parallel, and the wire harnesses are tightly adhered to the filler at the same time, the existing cable peeling machine is adopted for peeling, when the depth of the cutter reaches the depth capable of cutting the insulating coating and the filler, the sharp blade of the cutter scratches or cuts the wire harnesses twisted and wound together along with the axial movement of the cutter along the cable, thereby greatly reducing the reuse value of the wire harnesses in the cable, and only being put into reproduction after being recovered as base materials such as copper, plastic and the like.

Detailed Description
The following description of the embodiments of the present invention will clearly and fully describe the technical aspects of the embodiments of the present invention, and it is apparent that the described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the present invention without making any inventive effort, are intended to fall within the scope of the present invention.
Embodiment one:
as shown in fig. 1, referring to fig. 2, 4 and 5, a cable stripping device of the present invention is disposed on a horizontal plane and includes a positioning assembly 2, a first cutting assembly 3 and a second cutting assembly 4.
Wherein, set gradually locating component 2, first excision subassembly 3 and second excision subassembly 4 on the horizontal plane, first excision subassembly 3 sets up between locating component 2 and second excision subassembly 4.
The cable 1 in this embodiment is a stranded cable, and includes at least two wire harnesses 11, a protective layer 12 and a filler 13, wherein each wire harness 11 is disposed in the protective layer 12, at least two wire harnesses 11 are spirally wound together, and the filler 13 is filled in a gap between the wire harness 11 and the protective layer 12. The protective layer 12 actually includes an outermost rubber jacket and an inner insulating liner, and there may be a layer of armor between the rubber jacket and the insulating liner, but in this embodiment, they are collectively referred to as the protective layer 12; the filler 13 is typically fire-resistant fiber made of mica material, and a kraft paper is typically wrapped around the outer layer to enclose the strands 11 and fire-resistant fiber.
The cable 1 to be peeled sequentially passes through the positioning component 2, the first cutting component 3 and the second cutting component 4 along the horizontal direction, and the cable 1 can simultaneously move along the axial direction of the cable 1 and rotate along the axial direction of the cable 1 relative to the positioning component 2, the first cutting component 3 and the second cutting component 4. In the case of peeling, the cable 1 is generally transported by human force.
The positioning assembly 2 is used to limit the movement of the cable 1 relative to the positioning assembly 2 or the first cutting assembly 3 or the second cutting assembly 4 in a direction perpendicular to the axial direction of the cable 1.
Specifically, the positioning assembly 2 includes a base 21, a first ring 22, a second ring 23, and a limiting portion 24.
Wherein the base 21 is arranged on a horizontal plane; the first ring body 22 is arranged on the base 21, and the axial direction of the first ring body 22 is parallel to the axial direction of the cable 1; the second ring body 23 is arranged in the first ring body 22, the second ring body 23 axially rotates relative to the first ring body 22, and the second ring body 23 penetrates through the cable 1; the two limiting parts 24 are symmetrically arranged in the second ring body 23 around the axial lead of the second ring body 23, the two limiting parts 24 can move relative to the second ring body 23 along the radial direction of the second ring body 23 at the same time, the two limiting parts 24 are mutually abutted or mutually separated, the cable 1 is clamped between the two limiting parts 24, and the cable 1 passes through the axial lead of the second ring body 23.
The first cutting assembly 3 is used to cut the protective layer 12. The first cutting assembly 3 may be implemented by using an existing peeling device, and the cutting depth is adjusted to exactly cut the protective layer 12.
Specifically, as shown in fig. 1, in conjunction with fig. 6, the first cutting assembly 3 includes a bracket 31, a first rotating shaft 32, a second rotating shaft 33, a roller 34, and a cutter ring 35.
Wherein the bracket 31 is arranged on a horizontal plane; the first rotating shaft 32 and the second rotating shaft 33 are arranged on the bracket 31, both ends of the first rotating shaft 32 and the second rotating shaft 33 are both connected with the bracket 31 in a shaft way, the first rotating shaft 32 and the second rotating shaft 33 are arranged at intervals, the first rotating shaft 32 is positioned above the second rotating shaft 33, the first rotating shaft 32 and the second rotating shaft 33 extend horizontally and are vertical to the axial direction of the cable 1, and the first rotating shaft 32 and the second rotating shaft 33 can simultaneously rotate reversely under external driving; the two rollers 34 are respectively arranged on the first rotating shaft 32 and the second rotating shaft 33, the two rollers 34 synchronously rotate along with the first rotating shaft 32 and the second rotating shaft 33, the rollers 34 are contracted from two ends to the waist in equal proportion, the two rollers 34 are arranged at intervals, and the cable 1 passes through between the waists of the two rollers 34; the two knife rings 35 are respectively sleeved on the two rollers 34 and positioned at the waist of the rollers 34, the knife rings 35 synchronously rotate along with the rollers 34, the outer ring edges of the knife rings 35 are sharp, and when the cable 1 passes through the space between the waist of the two rollers 34, the two knife rings 35 symmetrically cut the protective layer 12 of the cable 1. To avoid damaging the wire harness 11 by the deeper cutting depth of the cutter ring 35, this is generally achieved by adjusting the spacing between the two rollers 34.
The second cutting assembly 4 is used for cutting the filler 13 to separate the adjacent wire harnesses 11 and axially rotate the cable 1 in the direction in which the wire harnesses 11 are spirally wound while axially moving the cable 1.
Specifically, the second cutting assembly 4 includes a cutter 41.
Wherein, the cutter 41 is arranged on a horizontal plane, the projection shape of the cutter 41 on the horizontal plane is triangular, one of the acute angles of the triangle is aligned with the axial lead of the cable 1, and the acute angle is the cutting edge part of the cutter 41, so that the cutter 41 can cut the cable 1 along the radial direction of the cable 1 when cutting the filler 13; when the cable 1 moves along the axial direction of the cable 1, the filler 13 on the side of the cutter 41, which is close to the horizontal plane, is cut by the acute angle of the cable 1, so that the adjacent two wire bundles 11 respectively move along the two side surfaces of the cutter 41 and are away from each other.
In order to peel the twisted wire cable 1 and ensure that the wire harness 11 in the cable 1 is not damaged, the working principle of the embodiment is that the protective layer 12 wrapped on the outer layer of the cable 1 is peeled off by the first cutting component 3 to expose the wire harness 11 and the filler 13, and the wire harness 11 and the filler 13 are usually stuck together and are difficult to separate at the moment, but an operator can already judge in which direction the wire harness 11 is spirally wound; at this time, the cable 1 continues to advance and the second cutting assembly 4 cuts the filler 13 to separate the adjacent wire bundles 11, and the wire bundles 11 can continue to move forward along the side surfaces of the cutters 41 after being separated from the filler 13, so that the side surfaces of the cutters 41 can be regarded as always moving along the wire bundles 11 and cutting the filler 13; because the adjacent wire harnesses 11 are spirally wound, when the side surface of the cutter 41 moves against the wire harnesses 11, the cable 1 can be axially rotated, so that the cutter 41 can avoid the cutter 41 from opening the wire harnesses 11 while cutting the filler 13, and damage to the cutter is avoided.
The cutter 41 is capable of cutting the filler 13 along the spiral winding direction of the wire harness 11 and driving the cable 1 to rotate, because the surface hardness of the cable 1 from which the protective layer 12 is peeled is still higher when the wire harness 11 is adhered to the filler 13, so that it can be regarded as a pipe surface having a higher surface hardness with a spiral wound trace, and the cutter 41 cuts the filler 13 along the trace.
It should be noted that, at this time, each wire harness 11 is not completely detached, because the second cutting assembly 4 actually cuts only the part of the filler 13 of the cable 1 facing the horizontal plane, so that the wire harness 11 wrapped in the filler 13 is exposed, thereby facilitating the subsequent processing by personnel.
Finally, it should be noted that, in general, a limiting mechanism is also installed on the second cutting assembly 4 to avoid the cable 1 from shifting left and right or being separated from the cutter 41 along with the rotation and swinging up and down in the process of rotation, but since the limiting mechanism is a conventional means, the installation of the limiting mechanism on the second cutting assembly 4 is also easy to be implemented, so the specific structure of the limiting mechanism is not described in detail herein; specifically, the same structure of the limiting portion 24 of the positioning assembly 2 can be adopted for the limiting purpose.
Embodiment two:
in an embodiment, in order to make the wire harness 11 move closer to the side of the cutter 41 more smoothly, as shown in fig. 1, in combination with fig. 3, the second excision assembly 4 further comprises a roller 42.
Wherein, two rollers 42 are symmetrically disposed on two sides of the cutter 41, the two sides 41 are two sides 41 which are clamped into an acute angle of the cutter 41 cutting the filler 13 in the embodiment, when the wire harness 11 moves along the sides of the cutter 41, the rollers 42 roll on the outer circumferential wall of the wire harness 11 along the extending direction of the wire harness 11, and the wheel surface of the rollers 42 is closely attached to the outer circumferential wall of the wire harness 11. However, in practical situations, since the side of the cutter 41 is smooth, and the wire harness 11 from which the filler 13 is peeled off is rotated away from the side of the cutter 41 after the cable 1 is rotated, the roller 42 is not required in practical devices.
Embodiment III:
in the first embodiment, since the width of the filler 13 filled between the adjacent two wire harnesses 11 is actually narrow, in order for the cutter 41 to penetrate into the filler 13 and cut the filler, the cutter 41 needs a sharp portion with a thin thickness to cut the filler 13; but at the same time, the cable 1 continuously moves forward horizontally and receives the cutting of the cutter 41, the cable 1 can impact the cutter 41, and the thickness of the cutter 41 cannot be too thin in order to avoid the cutter 41 from being damaged or broken by large impact.
In order to solve the above problem, the cutter 41 has a trapezoid cross section perpendicular to the axial direction of the cable 1, and the trapezoid side length near the center of the cable 1 is smaller than the trapezoid side length far away from the center of the cable 1, so that the cutter 41 has a large upper part, a small lower part, a thin and sharp top end extending into the cable 1 and cutting the filler 13, and a large bottom part, and has a strong supporting force and impact resistance.
Embodiment four:
on the basis of the first embodiment, in order to avoid an excessive cutting depth of the cutter ring 35 and to adapt to cables 1 of different sizes, the spacing between the two rollers 34 needs to be adjusted.
To solve this problem, as shown in fig. 1, in combination with fig. 7 and 8, the first cutting assembly 3 further includes a master gear 36, a slave gear 37, a transition gear 38, and a drive mechanism 39.
