Description

Technical Field

[0001] This invention relates to the field of cable outer layer stripping technology. Background Technology

[0002] Cables and wires are wire products used to transmit electrical energy, information, and realize electromagnetic energy conversion. With the rapid development of the communications industry, they have evolved from simple telephone and telegraph cables to multi-pair telephone cables, coaxial cables, optical cables, data cables, and even composite communication cables, bringing great convenience to people's lives. However, with the widespread use of cables and wires, a large number of them need to be recycled. Recycling waste cables and wires can save a lot of resources. Cables and wires are covered with insulation and metal layers. During recycling, the insulation and metal layers need to be stripped to recover the cable core. The metal layers are divided into stainless steel and copper layers. The stainless steel layer exists in a spiral winding manner in the cable, and the copper layer wraps around the inner cable core.

[0003] Currently, the commonly used cutting methods are manual cutting and machine cutting. If these wires are all cut manually, the outer insulation of the cable must first be cut, then the stainless steel layer must be unscrewed, and finally the cable core must be exposed by cutting. This method is labor-intensive due to the large number of cables.

[0004] Existing automatic wire stripping machines can only cut down to the insulation layer; the blades cannot penetrate the metal layer. They are bulky, inconvenient to operate, and costly. For the inner stainless steel layer of cables, workers can currently manually unscrew it using metal pliers or mechanically unscrew it by fixing both ends of the cable with a rotating mechanism. However, both methods are inefficient, and because the stainless steel layer is relatively long, mechanical unscrewing requires a more spacious working environment and carries the risk of breakage and injury. Furthermore, the irregular cross-section of cables, with variations between each section and even each layer, presents different challenges for manual stripping, requiring different stripping force and depth each time. The final product quality largely depends on the worker's experience. Therefore, a lightweight industrial wire stripping machine is needed that can cut both rubber and metal layers.

Each cutting blade is arranged circumferentially on the side of the inlet hole on the first mounting plate, with the inlet hole as the center, through the tool fixing device.

[0029] In this embodiment, the rubber layer cutting mechanism uses an annular straight knife chuck 5 as a tool fixing device and a straight knife as the cutting blade. The annular straight knife chuck 5 is coaxially arranged with the inlet hole on the first mounting plate 3. The annular straight knife chuck 5 has six straight knife slots circumferentially facing the center of the annular straight knife chuck 5. A threaded cavity is provided on the side of the straight knife slot near the outer circle of the annular straight knife chuck 5. A spring is provided in the cavity. One straight knife is provided in each straight knife slot. The straight knife is fixed in the straight knife slot by tightening the spring with a locking nut 4. The cutting direction of the straight knife is along the axial direction of the cable.

[0030] Rubber layer separation mechanism 24: The rubber layer separation mechanism 24 has a hemispherical structure. A through hole is opened in the center of the hemispherical structure from the curved side of the hemispherical structure to the flat side of the hemispherical structure. The flat side of the rubber layer separation mechanism 24 is located on the cable through hole entrance side of the second mounting plate 20. The through hole of the rubber layer separation mechanism 24 is coaxially arranged with the cable through hole on the second mounting plate 20.

[0031] Iron layer cutting mechanism: includes: lifting device, first cutting device, second cutting device, third cutting device, pressure sensor 9.

[0032] The lifting device includes a stepper motor 6, a lead screw 7, and a lead screw slider 8. The stepper motor 6 is fixedly mounted above the outlet side of the cable through hole of the second mounting plate 20 via the lifting device mounting bracket 30.

[0035] The second mounting bracket in the second cutting device includes a base plate 17, an adjusting bolt 18, and a spring 19. The base plate 17 is fixedly mounted on the second mounting plate 20 via the adjusting bolt 18. A spring 19 is positioned between the base plate 17 and the adjusting bolt 18, allowing the second cutting blade 14 of the second cutting device to move and adjust along the axial direction of the cable in the cable through-hole of the second mounting plate 20. The base plate 17 has a groove along the radial path of the cable. A slider is provided on the second blade drive mechanism mounting seat 16. The second blade drive mechanism 15 is slidably mounted on the groove of the base plate 17 via the second blade drive mechanism mounting seat 16 and is securely connected by fasteners, thereby enabling the second cutting blade 14 of the second cutting device to move and adjust radially along the cable. The third mounting bracket in the third cutting device has the same structure as the second mounting bracket of the second cutting device, and therefore will not be described further.

[0036] Conduit: such as Figure 2 As shown, in order to ensure that the cable can reach the target station smoothly during the processing, in this embodiment, a first conduit 31, a second conduit 32, and a third conduit 33 are respectively provided on the first mounting plate 3, the second mounting plate 20, and the third mounting plate 10 to shorten the cable transmission distance and ensure that the cable can smoothly enter the next station after cutting.

[0037] Specifically, the first mounting plate 3 has a first wire tube 31 coaxially arranged in the wire inlet hole. The wire inlet end of the first wire tube 31 is flush with the inlet end of the wire inlet hole, and the wire outlet end of the first wire tube extends beyond the outlet of the wire inlet hole toward the rubber layer separation mechanism 24. The first wire tube 31 has a channel for feeding each straight blade at the corresponding position of each straight blade in the rubber layer cutting mechanism.

[0038] The cable through hole of the second mounting plate 20 is provided with a second conductor tube 32 that is coaxially arranged with the cable through hole. The inlet end of the second conductor tube 32 is flush with the inlet end of the cable through hole, and the outlet end of the second conductor tube 32 extends beyond the outlet of the cable through hole toward the third mounting plate 10. The second conductor tube 32 is provided with a channel for feeding each cutting blade at the corresponding position of each cutting device in the iron layer cutting mechanism.

[0039] The third mounting plate 10 has a third guide tube 33 arranged coaxially with the outlet hole. The inlet end of the third guide tube 33 extends beyond the outlet hole in the direction of the iron layer cutting mechanism, and the outlet end of the third guide tube 33 is flush with the outlet hole.

[0040] Rubber layer recycling mechanism: includes a first recycling basin. A first opening 34 is provided on the base 23 between the first mounting plate 3 and the second mounting plate 20, and the first recycling basin is located below the first opening 34.

[0041] Metal layer recycling mechanism: includes a second recycling basin. A second opening 35 is provided on the base 23 between the second mounting plate 20 and the third mounting plate 10, and the second recycling basin is located below the second opening 35.

[0042] Cable exit mechanism: includes a pair of counter-rotating roller motors 12 and a second roller motor bracket 11. To accommodate cables of different diameters, the cable exit hole on the third mounting plate 10 is configured as an elongated through hole. The two counter-rotating roller motors 12 are positioned on the outlet side of the cable exit hole of the third mounting plate 10 via the second roller motor bracket 11, with an adjustable spacing along the length of the elongated through hole.

[0043] like Figure 4 The cable to be cut shown includes, from the outside to the inside: outer rubber layer 25, stainless steel layer 26, inner rubber layer 27, copper sheath layer 28, and core 29.

[0044] Before stripping the cable in this embodiment, the pressure of the cutting tool when cutting the iron layer of the cable is collected by the S-type pressure sensor in this embodiment. The force is controlled by the lifting device according to the pressure value of the target layer, so that the cutting tool only cuts to the designated layer without damaging the inner core. The pressure threshold for cutting the stainless steel layer is set in the control system according to the collected pressure data.

[0045] Then, the diameters of the infeed mechanism, rubber layer cutting mechanism, iron layer cutting mechanism, and outlet mechanism in this embodiment are adjusted according to the outer diameter of the cable: the spacing between the opposing rotating roller motors 1 in the infeed mechanism is adjusted according to the outer diameter of the cable. The depth of each straight blade on the annular straight blade chuck 5 in the rubber layer cutting mechanism is adjusted according to the thickness of the outer rubber layer 25 of the cable. The positions of the second cutting device and the third cutting device in the iron layer cutting mechanism are adjusted, specifically by adjusting the spacing between the base plate 17 and the second mounting plate by adjusting the adjusting bolt 18, thereby achieving the adjustment of the second cutting blade 14 device along the axial direction of the cable. After the second blade drive mechanism mounting seat 16 slides along the groove on the base plate 17 to the target position and locks it in place, the second cutting blade 14 of the second cutting device is adjusted radially along the cable. The adjustment method of the third cutting device is the same as that of the second cutting device. The spacing between the opposing rotating roller motors 12 in the outlet mechanism is adjusted according to the outer diameter of the cable.

[0046] Next, the cable is stripped using this embodiment: the cable is pressed into the annular straight knife chuck 5 by the roller 13 driven by the counter-rotating roller motor 1. The adjustable straight knife cuts the outer rubber layer 25 of the cable to be cut into six sections. The rubber layer is peeled off by the rubber layer separation mechanism 24. The scattered rubber layer falls into the first recycling basin through the first opening 34 on the base 23, exposing the cable wrapped in the stainless steel layer 26. Data is collected by the S-type pressure sensor, and feedback control is used to drive the stepper motor 6 to rotate the lead screw 7, causing the lead screw slider 8 to move vertically along the lead screw 7, thereby controlling the first cutting blade 36 of the first cutting device to precisely cut the cable. The stainless steel layer 26 of the cable is cut. The second cutting blade 14 of the second cutting device and the third cutting blade 37 of the third cutting device located below the cable perform auxiliary cutting. Since the stainless steel layer is attached to the cable in a sheet-like wrapped manner, the stainless steel layer 26 after being cut by the first cutting blade 36, the second cutting blade 14, and the third cutting blade 37 directly falls off the cable. After falling off, the stainless steel layer 26 of the cable falls into the second recycling basin through the second opening 35 on the base 23. The cable with the outer rubber layer 25 and the stainless steel layer 26 separated is finally pulled out of the machine by the drum 13 driven by the counter-rotating drum motor 12.

[0047] Finally, it should be noted that the above specific embodiments are only used to illustrate the technical solutions of the present invention and not to limit it. Although the present invention has been described in detail with reference to examples, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
