Description

Cable stripping device and stripping method

Technical Field

The invention relates to the technical field of cable peeling recovery, in particular to a cable peeling device and a peeling method.

Background

The cable has 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 playing the same or different roles are simultaneously wrapped in the insulating sheath, the protective sheath is wrapped outside the insulating sheath, and then fillers are filled in the wire harnesses to form the cable; some cables also have a layer of armor between the insulating jacket and the protective sheath to strengthen the jacket of the cable.

The cable is inevitably problematic in the long-term use process and becomes a waste product. In order to recover valuable materials in the cable and recover and recycle the wire harness in a good state in the cable, a peeler is generally used to peel the cable, and the wire harness in the cable is taken out by peeling off an insulating sheath, a protective sheath and an armor which are outer layers of the cable. The cable stripping machines available on the market are various in types, and can be used for stripping cables with various sizes.

The wiring harnesses in most cables 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 common parallel wire harness. Such cables are generally referred to in the industry as twisted-pair cables, and the types thereof include twisted-pair cables, three-stranded cables, four-stranded cables, five-stranded cables, and the like; meanwhile, the diameters of the respective wire harnesses spirally wound therein to each other may be different from each other.

When a cable is stripped by a cable stripping machine, a cutter of the cable stripping machine 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 harnesses in the cable from each other, the depth of the cutter is required to be capable of cutting an insulating sheath and a filler filled between the plurality of wires. For the cable with the parallel inner wire harnesses, the cutter can not damage the inner wire harnesses when cutting along the cable. However, when the twisted-pair cable is peeled, because the wire harnesses in the twisted-pair cable are not parallel but twisted and wound together, and the wire harnesses are also closely adhered to the filler, the existing cable peeling machine is adopted for peeling, when the depth of the cutter reaches the depth capable of cutting the insulating sheath and the filler, the sharp cutting edge of the cutter can scratch or cut off the twisted and wound wire harnesses along with the axial movement of the cutter along the cable, so that the recycling value of the wire harnesses in the cable is greatly reduced, and the wire harnesses can only be recycled as basic materials such as copper, plastics and the like and then put into reproduction.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without making any creative effort based on the embodiments of the present invention, belong to the protection scope of the present invention.

The first embodiment is as follows:

as shown in fig. 1, in conjunction with fig. 2, 4 and 5, a cable stripping device according to 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 up locating component 2, first excision subassembly 3 and second excision subassembly 4 on the horizontal plane in proper order, 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, where each wire harness 11 is disposed in the protective layer 12, the 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 here actually includes an outermost rubber outer sleeve and an inner insulating lining, and sometimes there is a layer of armor between the rubber outer sleeve and the insulating lining, but these are collectively referred to as protective layer 12 in this embodiment; the filler 13 is usually a refractory fiber made of mica, and a layer of kraft paper is usually wrapped around the outer layer to cover the bundles 11 and the refractory fiber.

A cable 1 to be stripped penetrates through the positioning component 2, the first cutting component 3 and the second cutting component 4 in sequence along the horizontal direction, and the cable 1 can move axially and rotate axially along the cable 1 relative to the positioning component 2, the first cutting component 3 and the second cutting component 4. In the case of stripping, the cable 1 is generally conveyed by human power.

The positioning assembly 2 serves to restrict the cable 1 from moving relative to the positioning assembly 2 or the first or second cut-out

assemblies

3, 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 rotates axially relative to the first ring body 22, and the cable 1 penetrates through the second ring body 23; the two limiting parts 24 are symmetrically arranged in the second ring body 23 around the axis 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 simultaneously and enable the two limiting parts 24 to approach each other or to be away from each other, and the cable 1 is clamped between the two limiting parts 24 and enables the cable 1 to pass through the axis of the second ring body 23.

The first cutting assembly 3 is used to cut through the protective layer 12. The first cutting assembly 3 can be an existing peeling device, and the cutting depth is adjusted to cut the protective layer 12.

Specifically, as shown in fig. 1 and 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, two ends of the first rotating shaft 32 and the second rotating shaft 33 are both coupled with the bracket 31, 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 perpendicular to the axial direction of the cable 1, and the first rotating shaft 32 and the second rotating shaft 33 can be driven by the outside to rotate reversely at the same time; the two rollers 34 are respectively arranged on the first rotating shaft 32 and the second rotating shaft 33, the two rollers 34 respectively rotate along with the synchronous shafts of the first rotating shaft 32 and the second rotating shaft 33, the diameters of the rollers 34 are reduced from two ends to the waist in equal proportion, the two rollers 34 are arranged at intervals, and the cable 1 passes through the waist of the two rollers 34; the two cutter rings 35 are respectively sleeved on the two rollers 34 and are positioned at the waist parts of the rollers 34, the cutter rings 35 rotate along with the synchronous shafts of the rollers 34, the edges of the outer rings of the cutter rings 35 are sharp, and when the cable 1 passes through the waist parts of the two rollers 34, the two cutter rings 35 symmetrically cut the protective layer 12 of the cable 1. In order to avoid damaging the wire harness 11 by the deep cutting depth of the cutter ring 35, the distance between the two rollers 34 is generally adjusted.

The second cut-out assembly 4 is used to cut the filler 13 to separate the adjacent strands 11 and to axially rotate the cable 1 in the direction in which the strands 11 are helically wound while moving the cable 1 axially.

In particular, the second cutting assembly 4 comprises a cutting knife 41.

The cutting knife 41 is arranged on a horizontal plane, the projection shape of the cutting knife 41 on the horizontal plane is triangular, one acute angle of the triangle is aligned with the axial lead of the cable 1, and the acute angle is the blade part of the cutting knife 41, so that the cable 1 can be split along the radial direction of the cable 1 when the cutting knife 41 cuts the filler 13; when the cable 1 moves along the axial direction of the cable 1, the acute angle of the cutting knife 41 aligned with the cable 1 cuts the filler 13 on the side of the cable 1 close to the horizontal plane, so that the two adjacent wire bundles 11 move along the two sides of the cutting knife 41 respectively and move away from each other.

In this embodiment, in order to peel off the stranded cable 1 and ensure that the wire harness 11 in the cable 1 is not damaged, the working principle of the method is that the protective layer 12 wrapped on the outer layer of the cable 1 is peeled off by the first cutting assembly 3 to expose the wire harness 11 and the filler 13, at this time, the wire harness 11 and the filler 13 are usually adhered together and are difficult to separate, but an operator can already judge which direction the wire harness 11 is spirally wound; at this time, the cable 1 continues to advance and is cut through the filler 13 by the second cutting assembly 4, so that the adjacent wire harnesses 11 are separated, and the wire harnesses 11 will continue to move forward along the side surfaces of the cutting knife 41 after being separated from the filler 13, so that the side surfaces of the cutting knife 41 can be regarded as moving along the wire harnesses 11 all the time and cutting the filler 13; since 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 is axially rotated, so that the cutter 41 can avoid the wire harnesses 11 while cutting the filler 13, thereby avoiding damage to the wire harnesses 11.

The reason why the cutter 41 can cut the filler 13 along the spiral winding direction of the wire harness 11 and drive the cable 1 to rotate is that the surface hardness of the cable 1 for stripping the protective layer 12 is still higher when the wire harness 11 and the filler 13 are stuck together, so that the surface of the pipe body with higher surface hardness can be regarded as a trace of spiral surrounding, and the cutter 41 cuts the filler 13 along the trace.

It should be noted that the individual strands 11 are not completely separated at this time, because the second cut-out assembly 4 actually cuts out only a portion of the filler 13 of the cable 1 facing the horizontal plane, so that the strands 11 enclosed in the filler 13 are exposed, thereby facilitating subsequent handling by personnel.

Finally, it should be noted that, a limiting mechanism is generally installed on the second cutting assembly 4 to prevent the cable 1 from deviating from the cutter 41 in the process of rotation or swinging up and down along with the 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 implement, and therefore, the specific structure of the limiting mechanism is not described in detail herein; specifically, the same structure as the stopper portion 24 of the positioning member 2 can be adopted for the purpose of stopper.

Example two:

in an embodiment, in order to make the wiring harness 11 move smoothly close to the side of the cutting knife 41, as shown in fig. 1, in conjunction with fig. 3, the second cutting assembly 4 further comprises a roller 42.

Wherein, two rollers 42 are symmetrically arranged on two sides of the cutting knife 41, the two sides 41 are two sides 41 which form an acute angle between the embodiment that the cutting knife 41 cuts the filler 13, when the wire harness 11 moves along the sides of the cutting knife 41, the rollers 42 roll on the peripheral wall of the wire harness 11 along the extending direction of the wire harness 11, and the roller surface of the rollers 42 is tightly attached to the peripheral wall of the wire harness 11. However, in actual conditions, since the side surface of the cutter 41 is smooth, and the wire harness 11 stripped of the filler 13 is also rotated to be away from the side surface of the cutter 41 after the cable 1 is rotated, the roller 42 is not required to be installed in actual equipment.

Example three:

in the first embodiment, since the width of the filler 13 filled between the two adjacent strands 11 is actually narrow, in order for the cutter 41 to penetrate into the filler 13 and cut the filler, a sharp portion having a small thickness is required for the cutter 41 to cut the filler 13; however, at the same time, the cable 1 continuously moves forward horizontally and is cut by the cutter 41, the cable 1 may 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 a large impact.

In order to solve the above problem, the section of the cutting knife 41 along the axial direction perpendicular to the cable 1 is trapezoidal, and the side length of the trapezoid close to the center of the cable 1 is smaller than the side length of the trapezoid far away from the center of the cable 1, so that the cutting knife 41 has a large upper part and a small lower part, a thin and sharp top end extends into the cable 1 and cuts the filler 13, and a large bottom has strong supporting force and impact resistance.

Example four:

on the basis of the first embodiment, in order to avoid the cutting depth of the cutter ring 35 from being too large, and to adapt to cables 1 with different sizes, the distance between the two rollers 34 needs to be adjusted.

To solve this problem, as shown in fig. 1 in conjunction 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 driving mechanism 39.

Wherein, the two main gears 36 are symmetrically arranged at two ends of the second rotating shaft 33; the two slave gears 37 are symmetrically arranged at two ends of the first rotating shaft 32, the two slave gears 37 move synchronously with the first rotating shaft 32, and the slave gears 37 with different outer diameters can be replaced according to the distance between the waist parts of the two rollers 34; the four transition gears 38 are symmetrically arranged on two sides of the bracket 31 in pairs, two transition gears 38 in each group are matched, and two transition gears 38 in each group are respectively matched with the main gear 36 and the driven gear 37; the driving mechanism 39 is disposed on a horizontal plane, and the driving mechanism 39 is connected to the second rotating shaft 33 and drives the second rotating shaft 33 to rotate axially. By adopting the transmission structure, the two rollers 34 can be driven to rotate reversely at the same time.

On the basis of this, the first rotating shaft 32 can move in a direction perpendicular to the horizontal plane relative to the bracket 31 and change the distance between the waists of the two rollers 34; in actual equipment, vertical sliding grooves are symmetrically formed in two sides of the support 31, sliding seats are arranged in the sliding grooves, two ends of the first rotating shaft 32 are connected with the two sliding seats in a shaft mode respectively, and the two sliding seats are driven to lift synchronously through a lead screw and a connecting rod.

Example five:

in addition to the first embodiment, in order to keep the cable 1 at the axial position of the second ring 23 when the cable 1 is clamped by the position-limiting portion 24, as shown in fig. 1 and with reference to fig. 9, the positioning assembly 2 further includes a fixing portion 25, a shaft 26, and a sleeve 27.

Wherein, the two fixing parts 25 are symmetrically arranged on the inner wall of the second ring body 23, and the two fixing parts 25 are arranged at intervals; the shaft lever 26 is arranged between the two fixing parts 25 along the moving direction of the limiting part 24, two ends of the shaft lever 26 are respectively coupled with the two fixing parts 25, one end of the shaft lever 26 passes through the fixing part 25 and is provided with a knob at the end; the two sleeves 27 are symmetrically sleeved on the shaft rod 26 and are close to two ends of the shaft rod 26 respectively, the two sleeves 27 rotate along with a synchronous shaft of the shaft rod 26, threads in opposite directions are formed in the peripheral walls of the two sleeves 27 respectively, and the two limiting portions 24 are in threaded connection with the two sleeves 27 in a one-to-one correspondence mode, so that the two limiting portions 24 can move simultaneously, and the moving distance is the same every time.

In addition, the base 21 can move in a direction perpendicular to the horizontal plane with respect to the horizontal plane, so that the height of the axis of the second ring 23 with respect to the horizontal plane is adjusted to keep the axis of the second ring 23 at the same level with the center of the distance between the two rollers 34 at all times.

The working principle is as follows:

a cable stripping method using the cable stripping device according to any one of embodiments one to five, comprising the following steps.

Step one, the end of the cable 1 is inserted into the positioning component 2, the distance between the two limiting parts 24 is adjusted, and the end of the cable 1 is clamped, so that the cable 1 just passes through the axis of the second ring body 23, and then the cable 1 is horizontally conveyed towards the direction of the first cutting component 3.

And step two, moving the cable 1 to enable the end part of the cable 1 to enter between the two rollers 34, starting an external mechanism to drive the two rollers 34 to rotate reversely at the same time, enabling the cable 1 to continue to be horizontal towards the direction of the second cutting assembly 4 under the driving of the rollers 34, and simultaneously, when the cable 1 passes between the two rollers 34, cutting the protective layer 12 symmetrically by the two cutter rings 35 to expose the wire harness 11 and the filler 13 which are adhered together.

And step three, the cable 1 is conveyed to the second cutting assembly 4 under the driving of the roller 34, the end part of the cable 1 abuts against the cutter 41, the cutter 41 cuts the filler 13 between the adjacent wire harnesses 11, and the adjacent wire harnesses 11 are respectively attached to and move along two side surfaces of the cutter 41 and are far away from each other.

Step four, when the cutting knife 41 is close to the spiral winding positions of the two wire harnesses 11, the wire harnesses 11 cling to the side surface of the cutting knife 41 and move along the side surface of the cutting knife 41, and the cable 1 is driven to axially rotate, so that the cutting knife 41 cuts the filler 13 to avoid the wire harnesses 11.

Step five, when the cable 1 rotates axially, the cable 1 drives the second ring body 23 to rotate relative to the first ring body 22, and when the cable 1 rotates in the first cutting assembly 3, the cutter ring 35 cuts the protective layer 12 along a curve.
