Description

Technical Field

[0001] The invention relates to the technical field of power cable recycling and reuse, and in particular to a cable classification and recycling device. Background Art

[0002] Cable is an electrical component used to transmit and distribute electrical energy, and is widely used in various links of the power system. The life of a cable is generally 10-30 years. For cables that have reached their predetermined life, they must be disassembled and recycled. There are many types of cables with different specifications. From the perspective of the number of cores, they can be divided into two categories: single-core cables and multi-core cables; from the perspective of whether they are armored, they can be divided into armored cables and unarmored cables. Figure 1 As shown, armored multi-core cable is a relatively complex cable form, which is composed of outer skin 1 as a sheath, armor layer 2, filling layer 3, insulation layer 4 and metal core 5 from outside to inside. Among them, metal core 5 and armor layer 2 can be recycled. The traditional cable disassembly process relies entirely on manual labor, which has the problems of high labor intensity and low disassembly efficiency. Although there are cable recycling equipment on the market, various problems have been found in the process of use, such as not being able to work efficiently in large quantities, not being able to classify and recycle armored cables, not being able to be suitable for separating multiple types of cables, not being able to achieve multiple uses of one machine, only being able to separate single-core unarmored cables, and not being able to effectively classify and recycle multi-core cables.

[0025] 4. The disassembly parameters of the present invention can be adjusted, with strong adaptability. The parameters can be pre-adjusted according to the cable model to achieve high-quality disassembly of the cable and improve the disassembly success rate.

[0026] 5. Through the cable conveying and straightening device and the classification recycling device, the present invention makes the finished products after disassembly more regular, which is convenient for storage, transportation and reprocessing, and improves the added value of the cable.

Specific implementation mode

[0058] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0059] The present invention discloses a Figure 3 The cable classification and recycling equipment shown in the figure includes a feeding device 7 for laying cables, a cable conveying and straightening device 8 for straightening cables in a bent state, a primary stripping and cutting and separating device 9 for stripping and removing the cable outer sheath 1 and the armor layer 2, and a secondary stripping and classification and recycling device 10 for stripping the filling layer 3 and the insulation layer 4.

[0060] The structure of the cable fixing frame 6 is as follows: Figure 2 As shown, it is a hollow cylindrical bracket. The retired cables are generally packed into rolls and rolled on the surface of the cable fixing frame 6. The cable as long as 100 meters is heavy after being rolled on the surface of the cable fixing frame 6. When the cable is released, Figure 5 As shown, the feeding device 7 utilizes the coiled shape of the cable fixing frame 6 to support the cable fixing frame 6 in the air so that it can automatically rotate around the center, thereby releasing the cables continuously and effectively aligning the cables with the subsequent equipment to facilitate feeding.

[0061] like Figure 4 and Figure 5 As shown, the feeding device 7 mainly comprises a base 7.1, a rotating support 7.6, a crossbeam 7.2 and a crossbeam supporting slide block 7.3.

[0062] The structure of the base 7.1 is as follows Figure 6 As shown, the upper part is used to support the rotating support 7.6, and the lower part fixes the entire mechanism on the ground, playing a connecting role. The bottom square base is arranged with multiple bolt holes, and the base 7.1 is fixed to the ground by inserting expansion bolts; a support platform 7.1.1 is set above the square base. The support platform 7.1.1 is a protruding cube with a very flat top surface, which is used to support the rotating support 7.6; a support sleeve 7.1.2 with a vertical center through hole is installed above the support platform 7.1.1. Figure 7As shown, a rotating support driving motor 7.1.3 and a motor gear 7.1.4 are installed inside the support sleeve 7.1.2. A blind hole is provided at the bottom of the rotating support 7.6. The blind hole is cylindrical and exactly matches the outer shape of the support sleeve 7.1.2. An internal gear 7.6.2 is installed in the blind hole at the bottom of the rotating support 7.6. The support sleeve 7.1.2, the rotating support driving motor 7.1.3, and the motor gear 7.1.4 are jointly inserted into the blind hole at the bottom of the rotating support 7.6. The motor gear 7.1.4 cooperates with the internal gear 7.6.2. Under the power action of the rotating support driving motor 7.1.3, the rotating support 7.6 can rotate around the support sleeve 7.1.2, and thus the rotating support 7.6 can rotate around the axis of the base 7.1 (as Figure 5 is the state diagram after relative rotation occurs between the base 7.1 and the rotating support 7.6).

[0063] The structure of the rotating support 7.6 is as Figure 4 , Figure 8 and Figure 9 shown, which is a hollow cuboid structure with the top surface and two opposite side surfaces being hollowed out and interconnected. In the central cavity part of the rotating support 7.6, a vertical trapezoidal slide rail 7.6.1 is installed on each of the left and right non-hollowed inner side walls. The structure of the crossbeam support slider 7.3 is as Figure 10 shown, with an approximate cuboid appearance shape. A vertical trapezoidal chute 7.3.1 is provided on each of the left and right side edges. The trapezoidal chute 7.3.1 cooperates with the trapezoidal slide rails 7.6.1 on both sides of the rotating support 7.6. After cooperation, the structure as Figure 4 shown is formed, which enables the crossbeam support slider 7.3 to only slide up and down in the hollow part of the rotating support 7.6 and cannot rotate up and down or horizontally.

[0064] As Figure 4 shown, there is a slider lifting transmission rack 7.5 arranged longitudinally on each of the front and rear sides of the two trapezoidal slide rails. The entire rotating support 7.6 contains a total of four slider lifting transmission racks 7.5. As Figure 11 and Figure 12 shown, a slider lifting driving motor 7.4 is installed in the diagonal direction of the top surface of the upper crossbeam support slider 7.3 and in the diagonal direction of the bottom surface of the lower crossbeam support slider 7.3. A gear that cooperates with the slider lifting transmission rack 7.5 is installed on each slider lifting driving motor 7.4. The slider lifting driving motor 7.4 drives the crossbeam support slider 7.3 to slide up and down in the hollow part of the rotating support 7.6 through the meshing transmission of the gear and the slider lifting transmission rack 7.5. Two crossbeam support sliders 7.3 are installed inside the rotating support 7.6. Each crossbeam support slider 7.3 is driven by two slider lifting driving motors 7.4. Therefore, two diagonally opposite slider lifting transmission racks 7.5 are used to provide support force, so that the crossbeam support slider 7.3 can achieve the greatest balance during movement.

[0065] As shown Figure 10 in the figure, a beam through hole 7.3.3 that runs through the front and back is provided inside the beam support slider 7.3, which is used to accommodate the beam 7.2 and enable the beam 7.2 to move back and forth in the beam through hole 7.3.3. There is a square downward through gear hole 7.3.4 on the lower side of the middle part of the beam through hole 7.3.3. A part of the beam movement driving gear 7.10 is installed in the gear hole 7.3.4 and meshes with the beam movement transmission rack 7.8 at the bottom of the beam 7.2. On the other surface of the beam support slider 7.3, on the opposite surface of the installation surface of the slider lifting driving motor 7.4, a beam movement driving motor 7.9 is installed. A beam movement driving gear 7.10 is installed on the output shaft of the beam movement driving motor 7.9.

[0066] There are two horn-shaped limiting abutting blocks 7.3.2 at the upper part of the beam through hole 7.3.3, which are used to limit the up and down movement of the beam 7.2. Since there are three semi-cylindrical through grooves for accommodating the rollers 7.7 on the surface of the beam 7.2, the horn shape can just avoid the three rollers 7.7, and at the same time can limit the beam 7.2 to slide only back and forth and not move in other directions.

[0067] Figure 11 and Figure 12 Figure 13 is a schematic structural diagram of the beam 7.2 and the beam support slider 7.3 installed together. The beam 7.2 is semi-cylindrical. There are three semi-cylindrical through grooves on the arc part of the semi-cylinder. The bottom of the through groove is arc-shaped, which is used to accommodate the rollers 7.7. A part of the rollers 7.7 is embedded in the through groove, and the other part is exposed outside. The rollers 7.7 can rotate along the arc surface of the through groove; when the cable fixing bracket 6 is mounted on the beam 7.2, the three rows of rollers 7.7 are tangent to the cylindrical inner hole of the cable fixing bracket 6. The three rows of rollers 7.7 can roll around their own axes, and the frictional force of the cable fixing bracket 6 rolling is greatly reduced, which helps the cable to be smoothly conveyed. There is a square through rack groove on the bottom plane part of the beam 7.2. The beam movement transmission rack 7.8 is installed in the rack groove. The beam movement driving motor 7.9 located on the beam support slider 7.3 drives the beam movement driving gear 7.10 to rotate. The beam movement transmission rack 7.8 drives the beam 7.2 to move back and forth along the beam through hole 7.3.3 under the transmission action of the rotation of the beam movement driving gear 7.10.

[0068] There are two crossbeam support sliders 7.3. The outer side surface of the crossbeam support slider 7.3 is slidably connected to the rotating support 7.6 and can slide up and down along the rotating support 7.6. A horizontal crossbeam through-hole 7.3.3 is provided in the middle part of the crossbeam support slider 7.3 for accommodating the crossbeam 7.2. The crossbeam 7.2 can move back and forth within the crossbeam through-hole 7.3.3 of the crossbeam support slider 7.3. There are also two crossbeams 7.2, which are slidably installed in the crossbeam through-holes 7.3.3 of the crossbeam support sliders 7.3 one by one. Since the rotating support 7.6, the crossbeam support slider 7.3 and the crossbeam 7.2 have different movement modes, from the perspective of the crossbeam 7.2, each crossbeam 7.2 can achieve three actions: back and forth, up and down, and rotation. After the two crossbeams 7.2 are inserted into the holes of the cable fixing bracket 6, the upper crossbeam 7.2 slides up to lift the cable fixing bracket 6. At this time, the upper crossbeam 7.2 is located at the top of the cylindrical inner hole of the cable fixing bracket 6, and the lower crossbeam 7.2 is located at the bottom of the cylindrical inner hole of the cable fixing bracket 6. The two crossbeams 7.2 support the cable fixing bracket 6 in mid-air and make it only rotatable and not movable. After the positions of the upper and lower crossbeams 7.2 are locked, the rotating support 7.6 starts to rotate until the axis of the crossbeam 7.2 is perpendicular to the cable disassembly production line. Use relevant tools to hold the cable head and transport it to the first transmission mechanism 8.2 of the cable transmission and straightening device 8. The cable is pulled out, and the three rows of rollers 7.7 on the surfaces of the upper and lower crossbeams 7.2 rotate freely, and the cable fixing bracket 6 also rotates under the pulling of the equipment. At this time, the crossbeam 7.2 can move back and forth, ensuring that the cable outlet is always near the axis of the cable transmission direction.

[0069] After the cable fixing bracket 6 is transported to the side of the feeding device 7 by a forklift or a crane, the cylindrical hole of the cable fixing bracket 6 is aligned with the feeding device 7. The crossbeam 7.2 of the feeding device 7 retracts to the back, the rotating support 7.6 rotates until the crossbeam 7.2 is aligned with the cylindrical inner hole of the cable fixing bracket 6. The two crossbeams 7.2 move vertically to the position closest to each other, and both crossbeams 7.2 are aligned with the cylindrical inner hole of the cable fixing bracket 6. The two crossbeams 7.2 extend and are inserted into the cylindrical inner hole of the cable fixing bracket 6, so that the crossbeam 7.2 completely penetrates the cable fixing bracket 6. The upper crossbeam 7.2 moves upward to lift the cable fixing bracket 6. As the cable fixing bracket 6 is lifted, the lower crossbeam 7.2 touches the lower edge of the cylindrical inner hole of the cable fixing bracket 6. The upper and lower crossbeams 7.2 maintain a certain pre-tightening force and move upward to the predetermined height at which the cable fixing bracket 6 is lifted. At this time, the rotating support 7.6 rotates around the base 7.1, so that the cable fixing bracket 6 can face the subsequent cable disassembly and recycling mechanism directly. The cable pulled out from the cable fixing bracket 6 can directly enter the subsequent cable disassembly and recycling mechanism.

[0070] The crossbeam 7.2 can move back and forth on the rotating support 7.6. When the front end of the crossbeam 7.2 retracts from the front side of the rotating support 7.6, the rear end of the crossbeam 7.2 extends from the rear side of the rotating support 7.6. Since the transmission support 7.6 can rotate 360°, this feature can be utilized to improve the installation and disassembly efficiency of the cable fixing bracket 6. If two cable fixing brackets 6 need to be installed in sequence, another cable fixing bracket 6 can be placed on the rear side of the rotating support 7.6. When the feeding of the first cable fixing bracket 6 is completed and it needs to be disassembled, during the retraction process of the crossbeam 7.2, the second cable fixing bracket 6 can be directly installed on the crossbeam 7.2 extending from the other side of the rotating support 7.6.

[0071] The cable conveying and straightening device 8 is used to straighten the bent cable. Retired cables are generally coiled on the surface of the cable fixing bracket 6, making the cable in a bent state. After the cable is released, due to metal memory, it remains arc-shaped. The arc-shaped cable is not convenient for storage and recycling after recovery. Straightening the cable can improve the recycling efficiency, reduce the space occupancy rate after recycling, and facilitate transportation. Since the models of waste cables vary, their diameters are also different. The cable conveying and straightening device 8 in the present invention does not limit the cable model, and cables of any thickness can be straightened by this device. At the same time, the cable conveying and straightening device 8 also has the function of measuring the diameter of the cable, and adjusts the parameters of the subsequent device according to the measured cable diameter to achieve the best use effect.

[0072] As Figure 13 and Figure 14 shown, the base 8.6 of the cable conveying and straightening device is located at the lower part of the cable conveying and straightening device 8, supporting all the upper mechanisms; above the base 8.6 of the cable conveying and straightening device, a first diameter measuring instrument 8.1, a first transmission mechanism 8.2, a dog tooth straightener 8.3, a second transmission mechanism 8.4 and a second diameter measuring instrument 8.5 are installed from left to right respectively. Both groups of diameter measuring instruments are laser diameter measuring instruments, used to detect the diameter of the cable, and a group is set at each end of the cable conveying and straightening device 8 to ensure that the diameter data of the cable can be measured when the cable starts to enter and when it is about to completely leave.

[0073] Figure 15 It is a structural diagram of the base 8.6 of the cable conveying and straightening device. The upper surface of the base 8.6 of the cable conveying and straightening device is successively a first bracket 8.2.2, a dog tooth straightener bracket 8.3.1 and a second bracket 8.4.1 from left to right. The first diameter measuring instrument 8.1 and the second diameter measuring instrument 8.5 are correspondingly installed at the left and right ends of the upper surface of the base 8.6 of the cable conveying and straightening device.

[0074] The structures of the first transmission mechanism 8.2 and the second transmission mechanism 8.4 are the same. As Figure 13 、 Figure 14 and Figure 16As shown, both include two horizontally axially arranged conveying rollers 8.2.1 symmetrically arranged up and down, two double-headed screws, and two servo motors installed on the tops of the double-headed screws. As Figure 13 and Figure 14 shown, the double-headed screws are vertically arranged in the first bracket 8.2.2 and the second bracket 8.4.1 at the corresponding ends respectively. A servo motor is installed on the top of each double-headed screw to control the rotation of the double-headed screw. The nuts 8.2.4 at both ends of the conveying roller 8.2.1 are respectively connected in corresponding cooperation with the two double-headed screws. The two double-headed screws rotate in the same direction and at the same speed. The upper and lower two conveying rollers 8.2.1 will rise or fall in parallel. The two double-headed screws arranged symmetrically left and right are respectively arranged at both ends of the conveying roller 8.2.1. Driven by the servo motor, the upper and lower two conveying rollers 8.2.1 can move towards each other (approach each other) or away from each other (move away from each other) along the double-headed screw. When the two conveying rollers 8.2.1 approach each other, they will tightly clamp the cable. The conveying roller 8.2.1 is sleeved outside the roller shaft 8.2.6. The roller rotation drive motor 8.2.5 drives the roller shaft 8.2.6 to rotate through the transmission gear set 8.2.3, and then drives the conveying roller 8.2.1 to rotate. After the two conveying rollers 8.2.1 clamp the cable, they rotate in the opposite direction at the same time, providing power for the cable to move forward and conveying the cable forward. The distance between the two conveying rollers 8.2.1 can be controlled by the rotation of the double-headed screw, and its size is set to be slightly smaller than the value measured by the two diameter gauges. By utilizing the characteristic that the conveying roller 8.2.1 can be slightly deformed, it can clamp the cable, ensuring sufficient downward pressure so that the cable can be effectively transmitted.

[0075] The threads at both ends of the double-headed screw are opposite, divided into positive threads and reverse threads. The threads on the nuts 8.2.4 of the upper and lower two conveying rollers 8.2.1 are also opposite, and are respectively installed at the positions of the positive threads and reverse threads on the double-headed screw. The nuts 8.2.4 at both ends of the roller shaft 8.2.6 are respectively matched with the two kinds of threads. When the double-headed screw rotates in one direction, the two conveying rollers 8.2.1 can move up and down along the axis of the double-headed screw, and the moving directions are opposite. This special thread form enables the two conveying rollers 8.2.1 to always move in the opposite direction.

[0076] The canine straightener 8.3 is used to adjust the bent cable into a straight cable, as Figure 13 、 Figure 14 、 Figure 17 、 Figure 18 and Figure 19As shown, the dog-leg straightener 8.3 is located exactly in the middle of the base 8.6 of the cable conveying and straightening device. It consists of two sets of dog-leg straightener brackets 8.3.1, dog-leg brackets 8.3.2, V-shaped frames 8.3.5, dog-leg rollers 8.3.4 and four push rod mechanisms 8.7 on the left and right. Each set of dog-leg straightener brackets 8.3.1 is equipped with two push rod mechanisms 8.7, and the two push rod mechanisms 8.7 are jointly connected to a set of dog-leg brackets 8.3.2. As Figure 17 and Figure 18 shown, multiple sets of V-shaped frames 8.3.5 are sequentially installed on the dog-leg bracket 8.3.2 along the cable conveying direction. Each set of V-shaped frames 8.3.5 includes two dog-legs perpendicular to each other. A dog-leg roller 8.3.4 that can roll around the dog-leg axis is sleeved outside each dog-leg, and a stop block 8.3.6 as Figure 19 shown is provided at the end of the dog-leg roller 8.3.4. The dog-leg roller 8.3.4 can rotate around the Figure 18 shown dog-leg. The dog-legs installed on the two sets of dog-leg straightener brackets 8.3.1 are arranged staggeredly. Bracket fixing blocks 8.3.3 are installed on both side faces at the two ends of each set of dog-leg brackets 8.3.2, and the bracket fixing blocks 8.3.3 are respectively connected to the corresponding push rod mechanisms 8.7. Under the action of the push rod mechanisms 8.7, the two sets of dog-leg brackets 8.3.2 can move towards each other. When they move close to each other, the two sets of dog-leg rollers 8.3.4 are interlaced with each other. As Figure 14 shown, the cross-section of the two sets of dog-leg brackets 8.3.2 is square after they approach each other. After the cable enters the cable conveying and straightening device 8 along the axis, it is tightly constrained within the square by multiple sets of dog-leg rollers 8.3.4. The preset side length of the square of the device is the diameter of the cable. At this time, the cable is constrained in four directions. Since there is a row of multiple dog-leg rollers 8.3.4 on the dog-leg bracket 8.3.2, the cable can only move forward in a straight line within a certain length, and the cable is forced to be straightened under the action of the dog-leg rollers 8.3.4. Since the dog-leg rollers 8.3.4 can roll, the resistance for the cable to move forward is very small, and it only receives the lateral pressure from the dog-leg rollers 8.3.4.

[0077] The cable passes through the first diameter measuring instrument 8.1, and the diameter data is recorded. Subsequently, it will enter the first transmission mechanism 8.2. The first transmission mechanism 8.2 obtains the data of the first diameter measuring instrument 8.1 and can adjust the spacing of the conveying rollers 8.2.1 to an ideal state (the spacing is slightly smaller than the cable diameter). Under the rotational force of the two conveying rollers 8.2.1, the cable gains forward momentum and enters the canine straightener 8.3. The canine straightener 8.3 straightens the cable on the one hand and restricts the up, down, left, and right movement of the cable on the other hand, fixing the position of the cable cross-section. After coming out of the canine straightener 8.3, the cable becomes straight and then passes through the second transmission mechanism 8.4. The second transmission mechanism 8.4 has the same function as the first transmission mechanism 8.1, which is to provide forward momentum for the cable and at the same time restrict its up, down, left, and right positions. The second diameter measuring instrument 8.5 measures the diameter of the cable again. The two diameter measuring instruments work together to ensure that the diameter data can be measured when the cable just enters the cable conveying and straightening device 8 and when it is about to completely leave the cable conveying and straightening device 8. After the cable passes through the second diameter measuring instrument 8.5, it enters the next process.

[0078] After the cable head comes out of the feeding device 7, it passes through the first diameter measuring instrument 8.1 to obtain diameter data. The diameter data is acquired by the first transmission mechanism 8.2, the dog tooth straightener 8.3, and the second transmission mechanism 8.4. The net distance between the two conveying rollers 8.2.1 in the first transmission mechanism 8.2 is adjusted to a value slightly smaller than the cable diameter (the outer side of the cable roller is made of rubber and can undergo slight deformation without causing the cable to be unable to pass through). The two conveying rollers 8.2.1 rotate relative to each other to drive the cable into the relevant device, providing power for the advancement of the cable. After the dog tooth straightener 8.3 receives the data from the first diameter measuring instrument 8.1, the spacing of the dog tooth straightener 8. is adjusted to the distance of the circumscribed square of the cable. After the cable head enters, multiple dog tooth rollers 8.3.4 restrict it within a square area and force the cable to straighten. Here, the inner core of the cable is made of metal material with strong plasticity, and the metal core 5 has been straightened, while the outer skin 1, the armor layer 2, the filling layer 3, and the insulation layer 4 still maintain their original arc trends. After the cable passes through the dog tooth straightener 8.3, it enters the second transmission mechanism 8.4. The second transmission mechanism 8.4 also acquires the data from the first diameter measuring instrument 8.1 and adjusts the distance between the two conveying rollers 8.2.1. The rotation of the second transmission mechanism 8.4 drives the cable to continue to advance (on the one hand, the second transmission mechanism 8.4 pulls the cable forward to force the cable to become straighter and easier to pass through the dog tooth straightener 8.3; on the other hand, the superposition of the two transmission mechanisms can provide the power for the advancement of the cable). After passing through the second transmission mechanism 8.4, the second diameter measuring instrument 8.5 measures the diameter information of the cable again, making the data more accurate on the one hand, and on the other hand, when the tail of the cable has passed through the first diameter measuring instrument 8.1, although the remaining part is still being conveyed forward within the first transmission mechanism 8.2 and the dog tooth straightener 8.3, the first diameter measuring instrument 8.1 can no longer measure the cable diameter data. The cable diameter data measured by the second diameter measuring instrument 8.5 provides a basis for the adjustment of the dog tooth straightener 8.3 and the second transmission mechanism 8.4.

[0079] As Figure 20 and Figure 21 shown, the primary peeling and truncating separation device 9 includes a primary peeling and truncating separation device base 9.6 and, arranged in sequence from left to right, an outer skin cutting mechanism 9.1, an armor layer cutting mechanism 9.2, a cable truncating mechanism 9.3, and an outer layer separation mechanism 9.4. The primary peeling and truncating separation device base 9.6 is as Figure 22As shown in the figure, it includes a cutting mechanism bracket 9.7 and an outer layer separation mechanism bracket 9.9. There is a through groove extending along the cable conveying direction between the two brackets, which is the first rack hole 9.8. The first rack hole 9.8 is used to install the first rack 9.3.4 at the bottom of the cable truncation mechanism 9.3. There is a square hole in the middle of the outer layer separation mechanism bracket 9.9, which is a leakage port 9.11 for the separated outer skin 1 and armor layer 2 of the cable to fall. At the outermost end of the upper surface of the primary peeling and truncation separation device base 9.6, there is a through groove perpendicular to the cable transmission direction, which is the second rack hole 9.10, used to install the second rack 10.1.6 at the bottom of the filling layer left and right side cutting mechanism 10.1. The first rack hole 9.8 and the second rack hole 9.10 enable the racks of the corresponding mechanisms to be installed on the lower surface of the primary peeling and truncation separation device base 9.6. On the lower surface of the tabletop of the primary peeling and truncation separation device base 9.6, multiple servo motors are also installed, which can drive the corresponding racks to move reciprocally.

[0080] The primary peeling and truncation separation device 9 is used to peel the outer skin 1 of the cable. If the cable has armor, the armor layer 2 can also be peeled off together. After passing through this part of the device, the cable is cut into appropriate lengths for convenient storage and transportation. At the same time, the peeled outer skin 1 and armor layer 2 are effectively separated from the internal structure to achieve classified recycling. If the cable is a multi-core cable, the secondary peeling and classification recycling device 10 can separate the filling layer 3 and insulation layer 4 of the cable, and recycle the metal core 5, filling layer 3, and insulation layer 4 in the cable core respectively. One machine can achieve the classified recycling of different components of various types and sizes of cables, such as single-core, multi-core, armored, and non-armored cables.

[0081] The primary peeling and truncation separation device 9 functions to peel the outer skin 1 of the cable and truncate it according to a predetermined length. The cable first passes through the outer skin cutting mechanism 9.1, which includes two outer skin cutting rollers 9.1.1 carrying outer skin rotary cutting knives 9.1.2. The rest of the structure is similar to the transmission mechanism, and both include a double-headed screw that can make the outer skin cutting rollers 9.1.1 move towards or away from each other simultaneously and a servo motor that controls the movement of the double-headed screw. Only there is a circular outer skin rotary cutting knife 9.1.2 in the middle of the outer skin cutting rollers 9.1.1 as shown in Figure 23 the figure. The upper and lower groups of outer skin cutting rollers 9.1.1 are adjusted to a spacing corresponding to the cable diameter according to the data of the two diameter gauges in the previous step. The spacing between the two groups of outer skin rotary cutting knives 9.1.2 is set to the cable diameter minus the thickness of the cable outer skin. When the cable passes between the two outer skin cutting rollers 9.1.1, the two outer skin rotary cutting knives 9.1.2 roll relative to each other to cut the outer skin 1 of the cable, exposing the internal structure of the cable. The two outer skin rotary cutting knives 9.1.2 cut the upper and lower parts of the cable respectively, cutting the outer skin 1 in half.

[0082] If the cable has an armor layer 2, there will be partial adhesion between the outer sheath 1 and the armor layer 2, making it impossible for the outer sheath 1 to fall off smoothly. At this time, after passing through the outer sheath cutting mechanism 9.1, the armor layer 2 at the cutting edge has been exposed; the cable continues to move forward to the armor layer cutting mechanism 9.2. The structure of the armor layer cutting mechanism 9.2 is similar to that of the outer sheath cutting mechanism 9.1, except that the outer sheath rotary cutting knife 9.1.2 is replaced by a serrated armor layer cutting knife capable of cutting the armor layer 2. The armor layer cutting knife continues to cut into the armor layer 2 along the cutting edge cut by the outer sheath rotary cutting knife 9.1.2. The rotation speed of the armor layer cutting knife is faster than that of the outer sheath rotary cutting knife 9.1.2, creating a speed difference between the two. The forward speed of the cable is the linear speed of the outer edge of the outer sheath rotary cutting knife 9.1.2, while the linear speed of the armor layer cutting knife is faster than the forward speed of the cable. This results in the armor layer cutting knife having a faster rotational speed relative to the cable. At this time, the serrated cutting edge produces a cutting effect similar to that of a angle grinder (like an angle grinder with a hacksaw blade installed cutting metal), which can effectively cut the armor layer 2.

[0083] The cable truncating mechanism 9.3 is used to truncate the cable. This mechanism truncates the cable of a corresponding length according to requirements without affecting the forward movement of the cable. The truncation of the cable is helpful for subsequent cable classification and recycling. The cable truncating mechanism 9.3 is as Figure 24As shown in the figure, it is a device for cutting cables. It can move reciprocally and move at the same speed as the cable when moving in the same direction as the cable. The mechanism includes two cutting knives 9.3.2 arranged symmetrically up and down. The two cutting knives 9.3.2 are respectively controlled by two groups of cutting push rods 9.3.1. The cutting knives 9.3.2 and the cutting push rods 9.3.1 are both installed inside the frame 9.3.5. There are two slide rails 9.3.3 at the bottom of the frame 9.3.5. A first rack 9.3.4 is installed at the middle position at the bottom of the frame 9.3.5. The first rack 9.3.4 cooperates with the servo motor and the gear, enabling the frame 9.3.5 to move back and forth on the slide rails 9.3.3, realizing the parallel reciprocating motion of the cable cutting mechanism 9.3. There is a speedometer 9.5 in front of the cable cutting mechanism 9.3, which can accurately measure the advancing speed of the cable. The cable cutting mechanism 9.3 starts to act according to the speed situation. According to the predetermined cutting length, after reaching the cutting point, the frame 9.3.5 moves in the same direction and at the same speed as the cable. At the same time, the cutting push rod 9.3.1 pushes the cutting knife 9.3.2 to move up and down. The two cutting knives 9.3.2 move towards each other to cut the cable, and the two cutting knives 9.3.2 touch together at the center of the cable, and the cable is cut off. The reciprocating motion direction of the frame 9.3.5 and the advancing direction of the cable are in the same direction. When cutting is required, the first rack 9.3.4 at the bottom of the frame 9.3.5 drives the frame 9.3.5 and its accessories to move in the same direction and at the same speed as the cable, keeping them relatively stationary. During the movement, the cutting knife 9.3.2 cuts down, the cable is cut off, the cutting knife 9.3.2 retracts, and the frame 9.3.5 returns to its original position. This ensures that cutting the cable will not affect the advancement of the cable on the production line. The cutting knife 9.3.2 includes a blade in the middle and knife frames on the upper, left, and right sides of the blade. When the two cutting knives 9.3.2 touch together, the two knife frames will touch together, preventing the blades from touching excessively, protecting the blades, and improving the cutting force of the entire cutting knife 9.3.2.

[0084] After passing through the cable cutting mechanism 9.3, the cable is conveyed to the outer layer separation mechanism 9.4. The outer layer separation mechanism 9.4 is used to separate the outer skin 1 and the armor layer 2 of the cable. After cutting the outer skin and the armor layer, the outer layer of the cable is cut open, but there is a situation of partial adhesion to the internal structure. The structural composition of the outer layer separation mechanism 9.4 is similar to that of the first transmission mechanism 8.2, except for the layout method. From Figure 21It can be seen that the two conveying rollers 8.2.1 are arranged crosswise up and down, forming an "x" shape. The two conveying rollers 8.2.1 are controlled by four double-headed screws and four servo motors. When the cable passes through, the upper and lower conveying rollers 8.2.1 twist the outer sheath 1 and the armor layer 2 to the left front and right front respectively at the position of the cable cutting edge. The two conveying rollers 8.2.1 twist respectively, so that the outer sheath 1 and the armor layer 2 are continuously separated from the filling layer 3. For the core part of the cable, since the two conveying rollers 8.2.1 move to the left front and right front respectively, the oblique forces acting on the core part cancel each other out, and the core part continues to move forward. After the outer sheath 1 and the armor layer 2 are peeled off, they fall into the material leakage port 9.11 of the primary peeling and truncating separation device base 9.6.

[0085] The secondary peeling and classification recycling device 10 includes, for example, Figure 20 , Figure 21 , Figure 25 , Figure 26 shown filling layer left and right side cutting mechanism 10.1 and as Figure 27 , Figure 28 shown filling layer upper and lower side cutting mechanism 10.2, insulation layer cutting mechanism 10.3, insulation layer separation mechanism 10.4, secondary peeling and classification recycling device base 10.5, end transmission mechanism 10.6 and receiving ramp 10.7.

[0086] Such as Figure 25 and Figure 26As shown in the figure, the left and right side cutting mechanism 10.1 of the filling layer is used to cut the left and right sides of the filling layer 3 in the horizontal direction. This mechanism includes a pair of filling layer side cutting rollers 10.1.2 rotatably installed at the end of the base 9.6 of the primary peeling and truncating separation device, three unpowered rotary cutters coated on the outside of the filling layer side cutting rollers 10.1.2, a baffle 10.1.1 installed on the outside of the filling layer side cutting rollers 10.1.2, a slider 10.1.4 for driving the movement of the baffle 10.1.1, a chute 10.1.3 for providing a movement track for the slider 10.1.4, a second rack 10.1.6, and a driving gear and motor. This mechanism has the functions of cutting the left and right sides of the filling layer 3, restricting the left and right movement of the cable, and blocking the outer skin 1 from passing through. Two second racks 10.1.6 are installed in the second rack holes 9.10 at the end of the base 9.6 of the primary peeling and truncating separation device. The second racks 10.1.6 penetrate upward through the chute 10.1.3 and are installed on the lower surface of the slider 10.1.4. There is an inverted trapezoidal notch on the upper surface of the chute 10.1.3 for accommodating the slider 10.1.4 at the bottom of the filling layer side cutting rollers 10.1.2 and enabling the slider 10.1.4 to move directionally in the chute 10.1.3. The second rack 10.1.6 cooperates with two motors installed on the chute 10.1.3. The motors can drive the second rack 10.1.6 to move horizontally through the driving gear, and then link to drive the two filling layer side cutting rollers 10.1.2, so that the two filling layer side cutting rollers 10.1.2 move towards the middle at the same time, clamping the cable. A square boss, namely the baffle orientation block 10.1.5, is connected to the upper surface of the slider 10.1.4. This boss is used to install the baffle 10.1.1. Because the boss is square, the baffle 10.1.1 will be fixed in direction after installation and will not swing back and forth. A roller shaft is installed on the baffle orientation block 10.1.5 for installing the filling layer side cutting rollers 10.1.2. The filling layer side cutting rollers 10.1.2 can rotate freely around the roller shaft. When the cable passes through, the two filling layer side cutting rollers 10.1.2 will move relatively under the drive of the servo motor to clamp the cable. Three unpowered rotary cutters are installed on the filling layer side cutting rollers 10.1.2 for cutting the filling layer 3 on the left and right sides of the cable. After the cable passes through, several cuts will be made on the left and right sides of the filling layer 3. The top of the baffle 10.1.1 is connected to the roller shaft, and the bottom is connected to the baffle orientation block 10.1.5, which is used to block the outer skin 1 and the armor layer 2 separated in the previous link, preventing the outer skin 1 and the armor layer 2 from entering the subsequent link and realizing the classification of cable disassembled objects.

[0087] The filling layer side cutting rollers 10.1.2 do not have their own power. It is the forward movement of the cable that drives their rotation, and the cable is cut while driving their rotation.

[0088] AsFigure 29 As shown, there are two integrated brackets 10.5.2 on the upper surface of the base 10.5 of the secondary peeling and classification recycling device. A material receiving port 10.5.1 is arranged below the integrated bracket 10.5.2 for receiving the separated insulating layer 4 and filling layer 3.

[0089] The functions of the filling layer upper and lower side cutting mechanism 10.2 and the filling layer left and right side cutting mechanism 10.1 are the same. Both are used to cut the filling layer 3. The filling layer cutting rollers in the filling layer upper and lower side cutting mechanism 10.2 are power-driven rotary cutters symmetrically arranged up and down. They cut the filling layer 3 at the upper and lower parts of the cable into multiple parts. Since the filling layer 3 on both the left and right sides of the cable has been cut, after passing through this mechanism, the filling layer 3 around the circumference of the cable is all cut. Under the extrusion of the two cutting rollers in the filling layer upper and lower side cutting mechanism 10.2, the filling layer 3 is separated from the cable core, and at the same time, the different cable cores of the multi-core cable are extruded into side-by-side cable cores (previously gathered together inside the cable and wrapped into a circle). After the filling layer 3 is cut, since the cable has just been straightened by the previous cable straightening device 8, the metal core 5 of the cable has strong rigidity and remains in a straight state. The filling layer 3 has material memory and becomes arc-shaped after being cut, so it automatically separates from the cable and falls into the lower material receiving port 10.5.1, realizing the separation of the cable core and the filling layer 3.

[0090] The insulating layer cutting mechanism 10.3 is located in the next process after the filling layer upper and lower side cutting mechanism 10.2. Its overall structure is similar to that of the first transmission mechanism 8.2, except that the rollers here become fine-tooth cutting rollers. The fine-tooth cutting rollers are used to cut the insulating layer 4 of multiple cable cores. When multiple cable cores pass through here, they are extruded and arranged side by side. The surface of the fine-tooth cutting rollers is densely covered with circular cutters. On the one hand, it can cut the insulating layer 4 of multiple cables. At the same time, the cutters are arranged in parallel, and there is a certain distance between two cutters. This distance is smaller than the diameter of the cable core. When the core part of the cable passes between the two cutters, the insulating skins on both sides are cut off, and the metal core can maintain a forward movement under the action of the two cutters, ensuring the forward direction of the cable core. The fine-tooth cutting rollers are also two groups symmetrically arranged up and down, and the control method is the same as that of the first transmission mechanism 8.2. Only the distance between the upper and lower groups of fine-tooth cutting rollers is closer than the distance between the two conveying rollers 8.2.1 in the first transmission mechanism 8.2, because since the diameter of the cable core is smaller than the diameter of the whole cable, after the cable cores are arranged side by side, the height is smaller than the height of the whole cable.

[0091] The insulating layer separating mechanism 10.4 is used to separate the insulating layer 4. The setting of this mechanism is the same as that of the outer layer separating mechanism 9.4. Two conveying rollers 8.2.1 arranged in an X shape twist the insulating layer 4 outside the metal core 5, separating the insulating layer 4 from the metal core 5. The insulating layer 4 is relatively soft and will fall off the metal core 5 and drop into the receiving port 10.5.1 below. By placing a basket or a conveyor belt below the receiving port 10.5.1, the insulating layer 4 can be collected separately. A basket or a conveyor belt can also be placed below the primary peeling and truncating separation device 9 to achieve the classified collection of the outer skin 1 and the armor layer 2.

[0092] After the insulating layer 4 is stripped off, only the metal core 5 remains of the cable. The metal core 5 continues to be transported forward and arrives at the end transmission mechanism 10.6. The end transmission mechanism 10.6 pushes the metal core 5 forward continuously. Since the cable has been cut into the set length in the cable truncating mechanism 9.3, after this section is completed, the metal core 5 of the cable will fall and slide down from the receiving slope 10.7.

[0093] The metal core 5 has strong plasticity. During the process of straightening the cable, an external force is used to straighten the metal core 5. In a short period of time, the filling layer 3, the outer skin 1 and other materials on the outer layer will still maintain their original shapes and will automatically curl when peeled later. This is a point that needs to be emphasized in the cable recycling process of the present invention.

[0094] The above content is the overall introduction of the equipment and the working process of the equipment when disassembling and recycling multi-core armored cables. For other forms of cables, there are the following types of working processes:

[0095] 1. If the cable is single-core without armor:

[0096] The cable is separated from the cable core by the outer layer separating mechanism 9.4 for the outer skin 1 cut by the outer skin cutting mechanism 9.1. The armor layer cutting mechanism 9.2 does not work. The two groups of armor layer cutting knives run to the uppermost and lowermost positions of the double-headed screw under the control of the double-headed screw, and the armor layer cutting knives do not contact the cable. The filling layer left and right side cutting mechanisms 10.1 in the secondary peeling and classification recycling device 10 are only used for limiting, and the subsequent mechanisms do not work and are only used to convey the cable core to the receiving slope 10.7. All kinds of rollers are only used for conveying and do not press tightly.

[0097] 2. If the cable is single-core with armor:

[0098] The working sequence is roughly the same as that of the first type of working process, and the difference is only that the armor layer cutting mechanism 9.3 will work to cut the armor layer 2.

[0099] 3. If the cable is multi-core without armor:

[0100] The working sequence is generally the same as that of the first type of working process, except that all parts of the secondary peeling and classification and recycling device 10 are working.

[0101] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
