Description

Technical Field

[0001] The present invention relates to the field of cable processing, and more particularly to a cable and a processing device and method thereof. Background Art

[0002] Cables are made of one or more mutually insulated conductors and an outer insulating protective layer. They are used to transmit electricity or information from one place to another. They are often used in urban underground power grids, lead-out lines of power stations, internal power supply of industrial and mining enterprises, and underwater transmission lines. When cables need to be recycled, the outer sheath of the cable usually needs to be peeled off to recover the cable core. When recycling cables in the prior art, a cutter is usually used to cut along the moving direction of the cable. However, when the cable is made of multiple conductors, spiral grooves will appear on the surface. At this time, the thickness of the outer insulation layer is uneven after the injection molding process is completed, and it is impossible to ensure that it is completely cut through during cutting, which makes subsequent peeling difficult. Summary of the invention

[0003] The invention provides a cable and a processing device and method thereof, aiming to be able to cut through the cable skin with the internal cable core being in a spirally wound shape.

[0004] The above purpose is achieved through the following technical solutions:

[0005] A cable processing device includes two rotating rings, each of which is fixedly connected to a plurality of fixed seats, each of which is provided with a sliding rod, each of which is fixedly connected to a wheel seat, a cutter is rotatably connected to a wheel seat of one of the rotating rings, and a pre-cutting wheel is rotatably connected to a wheel seat of the other rotating ring, and the pre-cutting wheel is provided with a plurality of pins.

[0006] Each pin is slidably connected to the pre-cutting wheel, and a tension spring is fixedly connected between each pin and the pre-cutting wheel.

[0007] The remaining fixed seats are all rotatably connected to a supporting wheel, and the multiple supporting wheels are arranged in parallel.

[0008] A method used by a cable processing device comprises the following steps;

[0009] S1: Insert one end of the cable into the processing equipment from one side of the pre-cutting wheel;

[0010] S2: Manually rotate the two driving rings to make the pre-cutting wheel and the cutter move along the tangent direction of the spiral line formed by the winding of the wire;

[0011] S3: drives the hydraulic rod to reciprocate and retract;

DETAILED DESCRIPTION

[0025] In the description of the present invention, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0026] The present invention will be further described below in conjunction with the accompanying drawings.

[0027] like Figures 1 to 5 , in order to solve the problem of completely cutting through the cable insulation.

[0028] The same number of fixed seats 101 are welded on both swivels 11, and the multiple fixed seats 101 are evenly distributed on the corresponding swivels 11. Each sliding rod 102 is slidably connected in the fixed seat 101, and the sliding rod 102 can rotate relative to the fixed seat 101. Multiple wheel seats 102 are welded on the corresponding sliding rods 102. The cutter 104 is rotatably connected to a wheel seat 102 of one swivel 11, and the pre-cutting wheel 105 is rotatably connected to a wheel seat 102 on the other swivel 11. The pre-cutting wheel 105 and the cutter 104 are symmetrically arranged with the axis of the swivel 11 as the center.

[0029] When the cable is stripped, the cable is placed in the processing equipment so that it passes through the rotating ring 11 corresponding to the pre-cutting wheel 105 first, and then the slide bar 102 is rotated to drive the wheel seat 102 to rotate, so that the direction of the cutter 104 and the pre-cutting wheel 105 is the same as the tangent direction of the spiral line formed by the winding of two adjacent wires 00, and then multiple slide bars 102 are moved downward to drive the wheel seat 102 to move downward, and then the slide bar 102 is locked with a screw, so that the pin 106 and the cutter 104 on the pre-cutting wheel 105 are inserted into the insulating skin 00, and then the cable is driven to move, and the two rotating rings 11 are driven to rotate at the same time. When the cable is formed by winding multiple wires 001, Gaps will be formed between the wires 001, making the wall thickness of the insulation skin 00 formed by injection molding uneven, and the wall thickness of the wires 001 at the contact point is thicker. Therefore, in the present invention, through the linear motion of the cable and the rotation of the swivel 11, the cutter 104 can move along the spiral line formed by winding, ensuring that the insulation skin 00 outside the cable can be cut through and the cutting effect is guaranteed. At the same time, the pre-cutting wheel 105 on the other swivel 11 has the same movement form as the cutter 104, so that the pin 106 thereon first punches a hole in the insulation skin 00, and then the cutter 104 cuts it, making cutting easier and preventing the cutter 104 from slipping during movement, thereby affecting the cutting effect.

[0030] like Figure 3 and Figure 4 , in order to avoid the problem that the pin 106 is inserted into the gap of the wire 001, thereby affecting the processing stability.

[0031] Each pin 106 is slidably connected to the pre-cutting wheel 105 , and a tension spring 107 is welded between the corresponding pin 106 and the pre-cutting wheel 105 .

[0032] When the pre-cutting wheel 105 moves relative to the cable, multiple pins 106 are inserted into the insulating skin 00 one by one, and then pulled out. Since the thickness of the insulating skin is likely to be uneven, and the pre-cutting wheel 105 always moves along the spiral line where the two wires 001 contact, it is easy for the pin 106 to be squeezed into the gap between the two wires 001, making it difficult to be pulled out. As the cable moves, the pin 106 shakes when it is pulled out. In the present invention, the pin 106 is pressed into the insulating skin by the elastic force of the tension spring 107. When the front end of the pin 106 touches the wire 001, the resistance of the wire 001 to the pin 106 is greater than the resistance of the insulating skin 00. At this time, the elastic force of the tension spring 107 is insufficient to continue to push the pin 106, thereby preventing the pin 106 from being squeezed into the gap between the wires 001.

[0033] like Figure 1 and Figure 5 , to solve the problem of cable support.

[0034] The plurality of support wheels 108 are rotatably connected to the remaining fixed seats 101 , and the plurality of support wheels 108 are arranged in parallel with the cutter 104 and the pre-cutting wheel 105 .

[0035] After the cable is placed in the processing equipment, the cable is located between multiple support wheels 108. The support wheels 108 support and fix the cable so that it is always located at the rotation center of the swivel 11, and fix it to prevent shaking, which affects the movement path of the support 104 and the pre-cutting wheel 105. Before processing, the slide bar 103 is rotated at the same time, which drives the wheel seat 102 to rotate, and then causes multiple support wheels 108 to rotate. When the cable moves in a straight line and the swivel 11 rotates, the support wheel 108 moves in a spiral along the surface relative to the cable, and the support wheel 108 always moves along the tangent direction of the spiral line, thereby reducing the resistance generated during the movement.

[0036] like Figure 5 and Figure 6 , in order to solve the problem of synchronously rotating multiple slide bars 103 so that the cutter 104, the pre-cutting wheel 105 and the supporting wheel 108 are parallel.

[0037] Each bevel gear 109 is rotatably connected to the corresponding fixed seat 101, the sliding rod 103 is provided with a groove, the bevel gear 109 is provided with a corresponding block, the block is slidably connected in the corresponding groove, the driving ring 110 is slidably connected between multiple fixed seats 101, and the driving ring 110 is provided with helical teeth 111 corresponding to the number of bevel gears 109, and the helical teeth 111 are meshed with the corresponding bevel gears 109.

[0038] Due to the different number of wires 001 inside the cable, the shape of the spiral line formed during winding is also different. Therefore, during processing, the drive ring 110 is rotated to drive the helical tooth shape 111 to move, thereby engaging and driving multiple bevel gears 109 to rotate. The bevel gear 109 and the slide bar 103 are slidably connected through the groove and the block, so that the bevel gear 109 can drive the slide bar 103 to rotate synchronously, and then drive the wheel seat 102 to rotate, so that the cutter 104, the pre-cutting wheel 105 and the supporting wheel 108 rotate to make them have the same tangent direction as the spiral line. At the same time, the connection method between the slide bar 103 and the bevel gear 109 can also avoid hindering the up and down movement of the slide bar 103, so that it can adapt to the processing of cables with different diameters.

[0039] like Figure 1 and Figure 7 To solve the problem of the rotation of the swivel 11

[0040] Each swivel frame 201 is rotatably connected to the outside of the corresponding swivel 11, and the two swivel frames 201 are locked on the bracket 12 by bolts. The two friction wheels 204 are rotatably connected to the corresponding swivel frames 12 respectively, and the friction wheels 204 are frictionally connected to the swivel 11 through the openings on the swivel frames 201.

[0041] When the swivel 11 needs to rotate, the two friction wheels 204 are driven to rotate at the same time, and then the two swivels 11 are driven by friction to rotate synchronously, and the swivel frame 201 and the bracket 12 can move relative to each other, and then they are locked by bolts, and then the position of the swivel frame 201 is moved to drive the swivel 11 to move, thereby changing the distance between the cutter 104 and the pre-cutting wheel 105 to adapt to spiral lines with different pitches.

[0042] like Figure 7 and Figure 8 , in order to solve the problem of the friction wheel 204 rotating.

[0043] Two threaded rods 202 are rotatably connected to both sides of the bracket 12 , a one-way bearing is provided between each threaded rod 202 and the bracket 12 , a square rod 203 is welded between the two threaded rods 202 , and each friction wheel 204 is slidably connected to the square rod 203 .

[0044] The threaded rod 202 is driven to rotate, thereby driving the square rod 203 to rotate, and then driving the two friction wheels 204 to rotate synchronously. The friction wheel 204 and the square rod 203 are slidably connected to avoid affecting the movement of the friction wheel 204. At the same time, the one-way bearing between the threaded rod 202 and the bracket 12 can ensure that the threaded rod 202 can only rotate in one direction.

[0045] like Figures 8 to 10 , to solve the problem of cable movement.

[0046] The slide 13 is slidably connected to the bracket 12, the hydraulic rod 205 is welded to the bracket 12, the moving end of the hydraulic rod 205 is fixedly connected to the slide 13, two clamp seats 301 are welded to the slide 13, each clamp seat 301 is rotatably connected with multiple clamps 302, two threaded rings 305 are provided on the slide 13, a one-way bearing is provided between each threaded ring 305 and the slide 13, and threaded transmission is achieved between the threaded rod 202 and the corresponding threaded ring 305.

[0047] The clamp 302 on the clamp seat 301 clamps the cable, and when the hydraulic rod 205 is extended, it drives the slide 13 to move forward, and then drives the clamp seat 301 to move, and then the cable clamped by the clamp 302 is moved forward synchronously, and at the same time, the threaded ring 305 moves synchronously with the slide 13. At this time, the threaded drive between the threaded ring 305 and the corresponding threaded rod 202, the one-way bearing between the threaded ring 305 and the slide 13 prevents it from rotating, and the one-way bearing between the threaded rod 202 and the bracket 12 allows it to rotate, and then when the slide 13 moves forward, the threaded rod 202 is driven to rotate by the threaded ring 305, and then the swivel 11 rotates synchronously when the cable moves forward to cut the insulation 00, similarly, when the slide 13 moves backward, the threaded rod 202 is stationary and the threaded ring 305 rotates, and the swivel 11 is stationary at this time.

[0048] like Figures 8 to 10 , in order to solve the problem of the clamp 302 clamping the cable.

[0049] The rubber head 303 is fixedly connected to the corresponding clamp 302 , and a compression spring 304 is fixedly connected between each clamp 302 and the corresponding clamp seat 301 .

[0050] The compression spring 304 pushes the moving end of the clamp 302 to make it close to the cable surface. The rubber head 303 is tooth-shaped. When the clamp seat 301 drives the clamp 302 to move forward, the beveled edge of the rubber head 303 contacts the cable surface. The beveled edge has a large friction coefficient, which increases the friction force and drives the cable forward. When the clamp seat 301 moves backward and resets, the straight edge of the rubber head 303 contacts the cable surface. The straight edge has a small friction coefficient, so the cable is not moved. The brackets 12 on both sides of the clamp seat 301 can support the cable to prevent the cable's own weight from affecting the clamping effect of the clamp 302.

[0051] The inside of the cable is a multi-strand spirally wound copper conductor 001, and the outside of the conductor 001 is provided with an injection-molded insulating sheath 00. Talcum powder is applied between the conductor 001 and the insulating sheath 00 to prevent interference.

[0052] like Fig.11 , a method used by a cable processing device, comprising the following steps;

[0053] S1: insert one end of the cable into the processing equipment from one side of the pre-cutting wheel 105, so that it passes through the clamp seat 302, two rotating rings 11 and another clamp seat 302 in sequence;

[0054] S2: Manually rotate the two driving rings 110 to make the pre-cutting wheel 105 and the cutter 104 along the tangent direction of the spiral line formed by the winding of the wire 001, so as to adapt to the winding of wires 001 of different thicknesses or quantities to form cables;

[0055] S3: driving the hydraulic rod 205 to reciprocate and contract to cut the insulation skin 00 on the cable surface;

[0056] S4: Separate the conductor 001 and the insulation 00.
