Description

Technical Field

[0001] This invention relates to the technical field of cables, specifically to a cable stripping machine. Background Technology

[0002] Cables generally consist of conductors, tape, and sheaths, with complex structures and multiple components. However, cable recycling requires different methods based on these components. Modern armored cables with complex structures often contain steel wires on the outside of the conductor. The conductor, sheath, and the wrapped steel wires are all valuable to recycle. While some equipment can perform mechanized stripping, it simply cuts the sheath, leaving it wrapped around the steel wires. Due to the wrapped steel wires, the cutting tool has poor clearance, resulting in poor cutting efficiency with existing methods. Furthermore, the steel wires need to be unwound in other ways, leading to unsatisfactory overall recycling results.

[0003] When dealing with armored cables, it is necessary to develop a stripping machine specifically for armored cables. Summary of the Invention

[0004] The purpose of this invention is to provide a cable stripping machine that solves the problem that there is currently no stripping machine for armored cables.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a cable stripping machine, wherein the cable stripping machine comprises...

[0006] Control panel;

[0007] The traction device is provided in two sets. The first set of traction devices is used to pull the unstripped cable, and the second set of traction devices is used to pull the conductor. The first set of traction devices and the second set of traction devices are set on the operating table.

[0008] The housing is disposed on the operating table and located between the first group of traction devices and the second group of traction devices;

[0009] The stripping knife assembly includes a support structure, a first knife assembly, and a second knife assembly. The support structure is located inside the housing on the side near the first traction device. The first knife assembly is rotatably located in the middle of the housing. The blades of the first knife assembly are inserted into the gaps between the steel wires of the cable and rotate when the cable advances. The second knife assembly is suspended inside the housing and is located on the side near the second traction device. The second knife assembly cuts the sheath.

[0010] A wire cutting device includes a straightening ring, a spreading ring, and a cutting unit. The straightening ring is rotatably mounted inside a housing, with a groove on its inner side. The straightening ring is fitted onto the outer side of the wire. The straightening ring rotates in the same direction as the first blade assembly, but its rotational speed is greater than that of the first blade assembly. The spreading ring is located on one side of the straightening ring, and its inner side slidably engages with a conductor. The wire slides along the outer side of the spreading ring. The cutting unit is located inside the housing and cuts the wire.

[0011] Furthermore, the supporting structure includes a first base, a first annular track, a supporting ring, and a connecting rod. The first base is fixedly installed inside the outer shell, the first annular track is rotatably installed on the inner side of the first base, and the outer side of the supporting ring and the first annular track are fixedly connected by the connecting rod.

[0012] Furthermore, the first blade assembly includes a second base, a connecting rod, a mounting sleeve, a first cutting blade assembly, and a second track. The second base is fixedly installed inside the outer casing, and the second track is rotatably installed inside the second base. The connecting rod is fixedly connected to the inner side of the second track and the outer side of the mounting sleeve. Two mounting sleeves are provided, and the two mounting sleeves are connected by bolts. The first cutting blade assembly includes a slanted blade, a transverse arc blade, and an insert rod. The slanted blade is fixedly installed on the inner side of the mounting sleeve and is inclined backward. The transverse arc blade is fixedly installed at the bottom of the slanted blade. The insert rod is fixedly installed on the bottom surface of the transverse arc blade and is inserted into the steel wire. The top surface of the transverse arc blade is inclined upward. Multiple first cutting blade assemblies are provided on the inner side of the mounting sleeve, and the transverse arc blades of the multiple first cutting blade assemblies are assembled into a ring.

[0013] Furthermore, the second blade assembly includes a mounting base, a spring, and a cutting blade. The mounting base is vertically and flexibly disposed within a sliding hole on the bottom surface of the second base. The spring is disposed within the sliding hole, and the cutting blade is disposed on the mounting base.

[0014] Furthermore, the straightening ring includes a first toothed ring, a first gear, a second gear, a second toothed ring, a drive shaft, a third base, a third track, a connecting rod, and a straightening seat. The third base is disposed inside the outer casing, and the third track is rotatably disposed on the inner side of the third base. The connecting rod is disposed on the outer side of the straightening seat and the inner side of the third track. The first toothed ring is concentrically disposed on the second track, and the second toothed ring is concentrically disposed on the third track. The drive shaft is rotatably disposed on the second base and the third base, and the first gear and the second gear are respectively disposed at both ends of the drive shaft. The first gear and the second gear mesh with the first toothed ring and the second toothed ring, respectively. The diameter of the second gear is larger than the diameter of the first gear. The inner cavity of the straightening seat has multiple grooves, and the outer side of the straightening seat is an inclined surface.

[0015] Furthermore, the expansion ring is mounted on a fixed seat inside the outer shell via a connecting rod. The outer contour of the expansion ring is rectangular, and the connecting rod is fixedly mounted on the outer side of the expansion ring.

The cylinder is mounted on the outer shell, the guide bracket is mounted inside the outer shell, the mounting plate is mounted on the guide bracket, the motor is mounted on the mounting plate, and the cutting tool is rotatably mounted on the mounting plate and connected to the motor. There are four sets of guide brackets, which are arranged parallel to the four outer sides of the expansion ring.

[0016] Furthermore, the traction device includes a traction motor, a traction wheel, and a bearing housing. The traction wheel is rotatably mounted on the bearing housing, which is mounted on the operating platform. The traction motor drives the traction wheel to rotate.

[0017] Beneficial effects:

[0018] The solution proposed in this application achieves the goal of recycling armored cables, enabling the recycling of the sheath and steel wire, and solving the problem that current stripping machines cannot recycle cables with steel wire wrapped around them.

[0019] 1. The first set of blades in this application slides along the gaps in the steel wires, with sufficient cutting depth. The cutting marks left by the first set of blades surround the cable. This cutting depth ensures that the sheath can be completely pierced. Existing stripping machines can only slide on the surface of the steel wires, with insufficient cutting depth, and damage to the blades. They cannot be used directly on armored cables. Furthermore, this application is the first to cut the sheath along the gaps in the steel wires during cable recycling, solving the problem of the current difficulty in cutting the sheath of armored cables.

[0020] 2. The second blade group of this application works in conjunction with the first blade group to cut the sheath. After the first blade group produces a ring-shaped cable noise on the sheath, the cutting marks of the second blade group will pass through the cutting marks of the first blade group, thereby achieving the purpose of cutting the sheath into multiple small pieces. The sheath cutting method is fast and simple.

[0021] 3. This application cuts the steel wire using the steps of removing the sheath contact constraint using the first and second blade sets, while the sliding first blade set initially loosens the steel wire; the faster rotating straightening ring can change the steel wire from a wound state to a parallel state. This straightening process can, on the one hand, remove the sheath adhering to the steel wire, and on the other hand, reduce the pressure of the next step of spreading; the spreading ring can spread the steel wire, and the cutting unit can then be used to cut it on the four sides of the spreading ring. The operation is simple. Attached Figure Description

For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0030] Please refer to the accompanying drawings. One embodiment of the present invention provides a cable stripping machine, primarily designed for armored cables, especially those with steel wire wound around the conductor. Because the spiral winding of the steel wire makes it impossible to strip the sheath in a single cut, axial or axial cutting is insufficient. Therefore, the cable stripping machine provided in this application includes...

[0031] Control panel 1;

[0032] The traction device 2 is provided in two sets. The first set of traction devices 2 is used to pull the unstripped cable, and the second set of traction devices 2 is used to pull the conductor. The first set of traction devices 2 and the second set of traction devices 2 are set on the operating table 1 and arranged in front of and behind each other.

[0033] The outer casing 3 is set on the operating table 1 and is located between the first traction device 2 and the second traction device 2. It can be seen that the cable sheath and steel wire are cut and stripped inside the outer casing 3. To achieve this process, a stripping knife set is set inside the outer casing 3.

[0034] The cable stripping assembly includes a support structure 4, a first blade assembly 5, and a second blade assembly 6. The support structure 4 is located inside the housing 3 near the first traction device 2. The support structure 4 includes a first base 7, a first annular track 8, a support ring 9, and a connecting rod 10. The first base 7 is fixedly located inside the housing 3. The first annular track 8 is rotatably located on the inner side of the first base 7. The outer side of the support ring 9 is fixed to the first annular track 8 via the connecting rod 10. The diameter of the support ring 9 matches the diameter of the cable, ensuring that the cable to the right of the support ring 9 is horizontal when it enters the first blade assembly 5. The first blade assembly 5 is rotatably located in the middle of the housing 3. The blades of the first blade assembly 5 engage with the gaps in the cable's wires and rotate as the cable advances. The first blade assembly 5 includes a second base 11, a connecting rod 12, a mounting sleeve 13, and a first cutting blade assembly. The second base 11 is fixedly installed inside the outer casing 3, and the second track 15 is rotatably installed inside the second base 11. The connecting rod 12 is fixedly connected to the inner side of the second track 15 and the outer side of the mounting sleeve 13. Two mounting sleeves 13 are provided and connected to each other by bolts 16. The first cutting blade assembly 14 includes a slanted blade 17, a transverse arc blade 18, and an insert rod 19. The slanted blade 17 is fixedly installed on the inner side of the mounting sleeve 13 and is inclined backward. The slanted blade 17 cuts the protective sleeve, and its inclined backward setting allows it to cut the protective sleeve first, reducing resistance. The transverse arc blade 18 is fixedly installed at the bottom of the slanted blade 17. After the slanted blade 17 has cut the protective sleeve, the transverse arc blade 18 can slide at the bottom of the protective sleeve. The insert rod 19 is fixedly installed on the bottom surface of the transverse arc blade 18 and is inserted into the steel wire.The top surface of the horizontal arc-shaped blade 18 is inclined upwards. Multiple first cutting blade assemblies 14 are provided on the inner side of the mounting sleeve 13. The horizontal arc-shaped blades 18 of the multiple first cutting blade assemblies 14 are assembled into a ring. When the horizontal arc-shaped blades 18 slide at the bottom of the sheath, the sheath can be lifted, achieving peeling. It is worth noting that the horizontal arc-shaped blades 18 assembled into a ring, combined with the inclined upward top surface, achieve peeling of the sheath. Thus, a spiral trajectory winding around the outer side of the steel wire is formed on the sheath. The second blade group 6 is suspended inside the outer shell 3 and is located near the second traction device 2. The second blade group 6 cuts the sheath. The second blade group 6, in conjunction with the aforementioned spiral trajectory, achieves cutting. The second blade group 6 includes a mounting base 20, a spring 21, and a cutting blade 22. The mounting base 20 is heightably mounted in a sliding hole on the bottom surface of the second base 11. The spring 21 is located within the sliding hole. The cutting blade 22 is mounted on the mounting base 20. The second blade group 6 is close to the first blade group 5 and faces the cable. The cutting blade 22 is in close contact with the steel wire. The trajectory of the cutting blade 22 interferes with the trajectory of the first blade group 5, achieving cutting. The cooperation between the first blade group 5 and the second blade group 6 can cut the sheath to the required size and solves the problem of the steel wire obstructing the cutting. It should be noted that the transverse arc-shaped blade 18 and the insert rod 19 of this application cooperate to allow the first blade group 5 to slide along the steel wire and the insert rod 19 to loosen the steel wire. As a guiding structure, the transverse arc-shaped blade 18 prevents the insert rod 19 from disengaging, ensuring stability during sliding.

[0035] The wire cutting device 23 includes a straightening ring 24, a spreading ring 25, and a cutting unit 26. The straightening ring 24 is rotatably mounted inside the housing 3. A groove 27 is provided on the inner side of the straightening ring 24, and the straightening ring 24 is fitted onto the outer side of the wire. The straightening ring 24 rotates in the same direction as the first blade assembly 5, and its rotational speed is greater than that of the first blade assembly 5. Since the rotational direction of the first blade assembly 5 is determined by the wire's spiral direction, the faster rotation of the straightening ring 24 allows the wire to contact the entangled state, detaching the wire from the conductor. Furthermore, the straightening ring 24 reduces the friction on the insertion rod 19 when straightening the wire. The spreading ring 25 is located on one side of the straightening ring 24. The inner side of the expanding ring 25 is slidably engaged with the conductor, and the steel wire slides along the outer side of the expanding ring 25. The cutting unit 26 is disposed inside the outer casing 3 to cut the steel wire. The straightening ring 24 includes a first toothed ring 28, a first gear 29, a second gear 30, a second toothed ring 31, a transmission shaft 32, a third base 33, a third track 34, a connecting rod 12, and a straightening seat 36. The third base 33 is disposed inside the outer casing 3, and the third track 34 is rotatably disposed on the inner side of the third base 33. The connecting rod 12 is disposed on the outer side of the straightening seat 36 and the inner side of the third track 34. The first toothed ring 28 is concentrically disposed on the second track 15, and the second toothed ring 31 is concentrically disposed on the third track 34. The transmission... The shaft 32 is rotatably mounted on the second base 11 and the third base 33, and the first gear 29 and the second gear 30 are respectively located at both ends of the transmission shaft 32. The first gear 29 and the second gear 30 mesh with the first gear ring 28 and the second gear ring 31, respectively. The diameter of the second gear 30 is larger than the diameter of the first gear 29. The inner cavity of the straightening seat 36 has multiple grooves 27, and the outer surface of the straightening seat 36 is inclined. In this way, the sheath bonded to the outside of the steel wire will be peeled off by the straightening seat 36, and the straightened steel wire will also accelerate the peeling off of the sheath. The spreading ring 25 is mounted on the fixed seat inside the outer shell 3 by the connecting rod 12. The outer contour of the spreading ring 25 is rectangular, and the connecting rod 12 is fixedly mounted on the outer side of the spreading ring 25. On the side, the steel wire is located outside the expansion ring 25. The cutting unit 26 includes a cylinder 37, a guide bracket 38, a mounting plate 39, a motor 40, and a cutting tool 41. The cylinder 37 is mounted on the outer shell 3, the guide bracket 38 is mounted inside the outer shell 3, the mounting plate 39 is mounted on the guide bracket 38, the motor 40 is mounted on the mounting plate 39, and the cutting tool 41 is rotatably mounted on the mounting plate 39 and connected to the motor 40. There are four sets of guide brackets 38, which are arranged parallel to the four outer sides of the expansion ring 25. The cylinder 37 drives the mounting plate 39 to slide, and the motor 40 drives the cutting tool 41 to rotate, thereby achieving the purpose of cutting the steel wire on the four sides of the expansion ring 25.

[0036] The traction device 2 includes a traction motor 42, a traction wheel 43, and a bearing seat 44. The traction wheel 43 is rotatably mounted on the bearing seat 44, which is mounted on the operating table 1. The traction motor 42 drives the traction wheel 43 to rotate.

[0037] Working principle:

[0038] A large-diameter armored cable is laid on the traction device 2. The diagonal cutter 17 is inserted into the sheath by bolt 16, and the insertion rod 19 is pulled into the steel wire. The traction device 2 drives the cable forward. During the forward movement of the cable, the diagonal cutter 17 slides along the steel wire, which causes the second track 15 to rotate, the first gear 29 to rotate, the drive shaft 32 to rotate, the second gear 30 to rotate, and finally the second gear ring 31 to rotate, the third track 34 to rotate, and the straightening seat 36 to rotate. As a result, the steel wire moves and is unwound from the entangled state.

[0039] The first blade group 5 and the second blade group 6 work together to cut the sheath.

[0040] Cylinder 37 drives mounting plate 39 to slide, motor 40 drives cutting tool 41 to rotate, cutting tool 41 achieves the purpose of wire cutting.

[0041] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
