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.

[0024] 4. The disassembly parameters of the present invention are adjustable and have strong adaptability. Various parameters can be pre-adjusted according to the cable model to achieve high-quality disassembly of the cable and improve the disassembly success rate.

[0025] 5.

[0028] 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.

[0029] 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.

[0030] 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.

[0031] 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.

[0032] 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 drive motor 7.1.3 and a motor gear 7.1.4 are installed in the support sleeve 7.1.2, a blind hole is provided at the bottom of the rotating support 7.6, and the blind hole is cylindrical, which just matches the 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 drive motor 7.1.3 and the motor gear 7.1.4 are inserted into the bottom blind hole of the rotating support 7.6 together, and the motor gear 7.1.4 cooperates with the internal gear 7.6.2. Under the power of the rotating support drive motor 7.1.3, the rotating support 7.6 can rotate around the support sleeve 7.1.2, thereby realizing the rotation of the rotating support 7.6 around the axis of the base 7.1 (such as Figure 5 7.1 and the rotating support 7.6 after relative rotation).

[0033] The structure of the rotating support 7.6 is as follows Figure 4 , Figure 8 and Fig. 9 As shown, it is a hollow rectangular parallelepiped structure with the top surface and two opposite side surfaces being hollowed out and connected. A vertical trapezoidal slide rail 7.6.1 is installed on the left and right inner walls of the central cavity of the rotating support 7.6. The structure of the crossbeam supporting the slider 7.3 is shown in FIG. Fig.10 As shown, the appearance is similar to a rectangular parallelepiped, and a vertically arranged trapezoidal slide groove 7.3.1 is provided on each of the left and right sides. The trapezoidal slide groove 7.3.1 cooperates with the trapezoidal slide rails 7.6.1 on both sides of the rotating support 7.6 to form a Figure 4 The structure shown can make the crossbeam supporting slider 7.3 only slide up and down in the hollow part of the rotating support 7.6, and cannot rotate up and down and horizontally.

[0034] like Figure 4 As shown, there is a slider lifting transmission rack 7.5 arranged through the entire length on the front and rear sides of the two trapezoidal slide rails, and the entire rotating support 7.6 includes a total of four slider lifting transmission racks 7.5. Fig.11 and Fig.12 As shown, a slider lifting drive motor 7.4 is installed in the diagonal direction of the top surface of the upper beam support slider 7.3 and the diagonal direction of the bottom surface of the lower beam support slider 7.3, and each slider lifting drive motor 7.4 is installed with a gear that matches the slider lifting transmission rack 7.5. The slider lifting drive motor 7.4 drives the beam support slider 7.3 to slide up and down on the hollow part of the rotating support 7.6 through the meshing transmission action of the gear and the slider lifting transmission rack 7.5. Two beam support sliders 7.3 are installed inside the rotating support 7.6, and each beam support slider 7.3 is driven by two slider lifting drive motors 7.4. Therefore, two diagonal slider lifting transmission racks 7.5 are used to provide support force, so that the beam support slider 7.3 can achieve maximum balance when moving.

[0035] like Fig.10 As shown, a beam through hole 7.3.3 is provided in the beam support slider 7.3, which is used to accommodate the beam 7.2 and enable the beam 7.2 to move forward and backward in the beam through hole 7.3.3. A square gear hole 7.3.4 is provided at the lower middle part of the beam through hole 7.3.3, and a part of the beam moving driving gear 7.10 is installed in the gear hole 7.3.4 and meshes with the beam moving transmission rack 7.8 at the bottom of the beam 7.2. A beam moving driving motor 7.9 is installed on the other surface of the beam support slider 7.3, which is opposite to the mounting surface of the slider lifting driving motor 7.4, and a beam moving driving gear 7.10 is installed on the output shaft of the beam moving driving motor 7.9.

[0036] There are two ram-horn-shaped limit blocks 7.3.2 on the upper part of the cross beam through hole 7.3.3, which are used to limit the up and down movement of the cross beam 7.2. Because there are three semi-cylindrical through grooves on the surface of the cross beam 7.2 for accommodating the rollers 7.7, the ram-horn shape can just avoid the three rollers 7.7, and at the same time can limit the cross beam 7.2 to slide forward and backward, and cannot move in other directions.

[0037] Fig.11 and Fig.12 It is a structural schematic diagram of the crossbeam 7.2 and the crossbeam supporting slider 7.3 installed together. The crossbeam 7.2 is semi-cylindrical, and the arc part of the semi-cylindrical part has three semi-cylindrical through grooves. The bottom of the through groove is arc-shaped for accommodating rollers 7.7. A part of the roller 7.7 is embedded in the through groove, and the other part is exposed outside. The roller 7.7 can rotate along the arc surface of the through groove; when the cable fixing frame 6 is mounted on the crossbeam 7.2, the three rows of rollers 7.7 are tangent to the cylindrical inner hole of the cable fixing frame 6, and the three rows of rollers 7.7 can roll around their own axis, and the friction of the rolling of the cable fixing frame 6 is greatly reduced, which is conducive to the smooth transportation of the cable. The bottom plane part of the crossbeam 7.2 has a square through rack groove, in which a crossbeam moving transmission rack 7.8 is installed. A crossbeam moving drive motor 7.9 located on the crossbeam supporting slider 7.3 drives the crossbeam moving drive gear 7.10 to rotate. The crossbeam moving transmission rack 7.8 drives the crossbeam 7.2 to move forward and backward along the crossbeam through hole 7.3.3 under the transmission action of the rotation of the crossbeam moving drive gear 7.10.

[0038] The cross beam support slider 7.3 has two pieces, the outer side of the cross beam support slider 7.3 is slidably connected with the rotating support 7.6, and can slide up and down along the rotating support 7.6. The middle part of the cross beam support slider 7.3 is provided with a horizontal cross beam through hole 7.3.3 for accommodating the cross beam 7.2, and the cross beam 7.2 can move forward and backward in the cross beam through hole 7.3.3 of the cross beam support slider 7.3; the cross beam 7.2 also has two pieces, which are slidably installed in the cross beam through hole 7.3.3 of the cross beam support slider 7.3 one by one. Since the rotating support 7.6, the cross beam support slider 7.3 and the cross beam 7.2 have different movement modes, each cross beam 7.2 can realize three movements of forward and backward, up and down, and rotation when viewed on the cross beam 7.2. After the two crossbeams 7.2 are inserted into the holes of the cable fixing frame 6, the upper crossbeam 7.2 slides upward to lift the cable fixing frame 6. At this time, the upper crossbeam 7.2 is located at the top of the cylindrical inner hole of the cable fixing frame 6, and the lower crossbeam 7.2 is located at the bottom of the cylindrical inner hole of the cable fixing frame 6. The two crossbeams 7.2 make the cable fixing frame 6 erected in mid-air and can only rotate but not move. After the positions of the upper and lower crossbeams 7.2 are locked, the rotating support 7.6 starts to rotate until the axial direction of the crossbeam 7.2 is perpendicular to the cable disassembly assembly line. The cable head is clamped with relevant tools and transported to the first transmission mechanism 8.2 of the cable conveying and straightening device 8. The cable is pulled out, and the three rows of rollers 7.7 on the surface of the upper and lower crossbeams 7.2 rotate freely, and the cable fixing frame 6 also rotates under the pull of the equipment. At this time, the crossbeam 7.2 can move forward and backward, ensuring that the cable outlet is always near the axis of the cable transmission direction.

[0039] After the cable fixing frame 6 is transported to the side of the feeding device 7 by a forklift or a crane, the cylindrical hole of the cable fixing frame 6 is made to face the feeding device 7, the crossbeam 7.2 of the feeding device 7 is retracted to the rear, the rotating support 7.6 is rotated until the crossbeam 7.2 faces the cylindrical inner hole of the cable fixing frame 6, the two crossbeams 7.2 are vertically moved to the position closest to each other, and the two crossbeams 7.2 are made to face the cylindrical inner hole of the cable fixing frame 6, the two crossbeams 7.2 are extended and inserted into the cylindrical inner hole of the cable fixing frame 6, so that the crossbeam 7.2 completely penetrates the cable fixing frame 6 , the upper crossbeam 7.2 moves upward to lift the cable fixing frame 6. As the cable fixing frame 6 is lifted, the lower crossbeam 7.2 touches the lower edge of the cylindrical inner hole of the cable fixing frame 6. The upper and lower crossbeams 7.2 maintain a certain pre-tightening force and move upward to a predetermined height at which the cable fixing frame 6 is lifted. At this time, the rotating support 7.6 rotates around the base 7.1, so that the cable fixing frame 6 can face the subsequent cable disassembly and recovery mechanism, and the cables pulled out from the cable fixing frame 6 can directly enter the subsequent cable disassembly and recovery mechanism.

[0040] The crossbeam 7.2 can move forward and backward on the rotating support 7.6. When the front end of the crossbeam 7.2 is retracted 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 ​​degrees, this can be used to improve the efficiency of installing and removing the cable fixing frame 6. If two cable fixing frames 6 need to be installed in sequence at the same time, the other cable fixing frame 6 can be placed on the rear side of the rotating support 7.6. When the first cable fixing frame 6 is fed and needs to be removed, the crossbeam 7.2 is retracted, and the second cable fixing frame 6 is directly installed on the crossbeam 7.2 extending from the other side of the rotating support 7.6.

[0041] The cable conveying and straightening device 8 is used to straighten the cable in a bent state. The retired cables are generally coiled on the surface of the cable fixing frame 6, so that the cables are in a bent state. After the cables are released, they are still in an arc shape due to metal memory. The arc-shaped cables are not convenient to store and preserve after recycling. Straightening the cables can improve the recycling efficiency, reduce the space occupancy rate after recycling, and facilitate transportation. Since the types of waste cables are different, the diameters are all different. The cable conveying and straightening device 8 in the present invention does not limit the cable type. Regardless of the thickness of the cable, it can be straightened by this device. At the same time, the cable conveying and straightening device 8 also has the function of measuring the cable diameter. According to the measured cable diameter, the parameters of the subsequent device are adjusted to achieve the best use effect.

[0042] like Fig.13 and Fig.14 As shown, the cable conveying and straightening device base 8.6 is located at the lower part of the cable conveying and straightening device 8, supporting all the mechanisms at the upper part; the first caliper 8.1, the first transmission mechanism 8.2, the dog tooth straightener 8.3, the second transmission mechanism 8.4 and the second caliper 8.5 are installed from left to right above the cable conveying and straightening device base 8.6. Both sets of calipers are laser calipers, which are used to detect the diameter of the cable. One set is set at the head and the tail of the cable conveying and straightening device 8, and the speed meter ensures that the cable diameter data can be measured when the cable starts to enter and when it is about to leave completely.

[0043] Fig.15 This 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 composed of the first bracket 8.2.2, the dog tooth straightener bracket 8.3.1 and the second bracket 8.4.1 from left to right. The first caliper 8.1 and the second caliper 8.5 are correspondingly installed on the left and right ends of the upper surface of the base 8.6 of the cable conveying and straightening device.

[0044] The first transmission mechanism 8.2 and the second transmission mechanism 8.4 have the same structure. Fig.13 , Fig.14 and Fig.16As shown, they all include two conveying rollers 8.2.1 with horizontal axes symmetrically arranged at the upper and lower parts, two double-headed screws and two servo motors installed on the top of the double-headed screws. Fig.13 and Fig.14 As shown, the double-headed screw rods are vertically arranged in the first bracket 8.2.2 and the second bracket 8.4.1 at the corresponding ends, and a servo motor is installed on the top of each double-headed screw rod to control the rotation of the double-headed screw rod. The nuts 8.2.4 at both ends of the conveying roller 8.2.1 are respectively connected with the two double-headed screw rods in a corresponding manner. The two double-headed screw rods rotate in the same direction and at the same speed. The upper and lower conveying rollers 8.2.1 will rise or fall in parallel. The two double-headed screw rods arranged symmetrically on the left and right are respectively set at the two ends of the conveying roller 8.2.1. Driven by the servo motor, the upper and lower conveying rollers 8.2.1 can run toward each other (approaching each other) or away from each other (moving away from each other) along the double-headed screw rods. When the two conveying rollers 8.2.1 approach each other, they will tightly clamp the cable. The conveying roller 8.2.1 is mounted on the outside of the roller shaft 8.2.6. The roller rotation driving 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 opposite directions at the same time, providing the cable with forward power and conveying the cable forward. The spacing 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 of the conveying roller 8.2.1 being slightly deformable, it can be clamped to ensure sufficient downward pressure, so that the cable can be effectively transmitted.

[0045] The threads at both ends of the double-headed screw are opposite, divided into positive threads and negative threads. The threads on the nuts 8.2.4 of the upper and lower conveying rollers 8.2.1 are also opposite, corresponding to the positions of the positive threads and negative threads installed on the double-headed screw respectively. The nuts 8.2.4 at both ends of the roller shaft 8.2.6 cooperate with the two threads respectively. 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 movement directions are opposite. This special thread form enables the two conveying rollers 8.2.1 to always maintain reverse movement.

[0046] The dog tooth straightener 8.3 is used to adjust a bent cable to a straight cable, such as Fig.13 , Fig.14 , Fig.17 , Fig.18 and Fig.19As shown, the dog tooth straightener 8.3 is located in the middle of the cable conveying and straightening device base 8.6, and is composed of two groups of left and right dog tooth straightener brackets 8.3.1, dog tooth brackets 8.3.2, V-shaped brackets 8.3.5, dog tooth rollers 8.3.4 and four push rod mechanisms 8.7. Each group of dog tooth straightener brackets 8.3.1 is equipped with two push rod mechanisms 8.7, and the two push rod mechanisms 8.7 are connected to a group of dog tooth brackets 8.3.2. Fig.17 and Fig.18 As shown, a plurality of groups of V-shaped frames 8.3.5 are sequentially installed on the dog tooth bracket 8.3.2 along the cable transmission direction, each group of V-shaped frames 8.3.5 includes two dog teeth perpendicular to each other, each dog tooth is provided with a dog tooth roller 8.3.4 that can roll around the dog tooth axis, and the end of the dog tooth roller 8.3.4 is provided with Fig.19 The dog tooth roller 8.3.4 can be wound around Fig.18 The canine teeth shown in the figure rotate, and the canine teeth installed on the two sets of canine tooth straightener brackets 8.3.1 are staggered. The two end sides of each set of canine tooth brackets 8.3.2 are installed with bracket fixing blocks 8.3.3, 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 canine tooth brackets 8.3.2 can move towards each other. When the two move to a relatively close position, the two sets of canine tooth rollers 8.3.4 are staggered, as shown in FIG. Fig.14 As shown, when the two groups of dog tooth brackets 8.3.2 are close to each other, their cross-section is square. After the cable enters the cable conveying and straightening device 8 along the axis, it is tightly bound in the square by multiple groups of dog tooth rollers 8.3.4. The equipment presets the side length of the square as the diameter of the cable. At this time, the four directions of the cable are all bound. Since the dog tooth bracket 8.3.2 has a row of multiple dog tooth rollers 8.3.4, the cable can only move in a straight line within a certain length, and the cable is forced to be straightened under the action of the dog tooth rollers 8.3.4. Since the dog tooth rollers 8.3.4 can roll, the cable has little resistance to moving forward in it and is only subjected to lateral pressure from the dog tooth rollers 8.3.4.

[0047] The cable passes through the first caliper 8.1, and the diameter data is recorded. Then the cable enters the first transmission mechanism 8.2. The first transmission mechanism 8.2 obtains the data of the first caliper 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 has the forward power and enters the dog tooth straightener 8.3. The dog tooth straightener 8.3 straightens the cable on the one hand, and limits the up, down, left and right movement of the cable on the other hand, so that the position of the cable cross section is fixed. After coming out of the dog tooth 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, both of which provide the cable with forward power and limit its up, down, left and right position. The second caliper 8.5 measures the cable diameter again. The two calipers work together to ensure that the diameter data of the cable can be measured when it just enters the cable conveying and straightening device 8 and when it is about to leave the cable conveying and straightening device 8. After passing the second caliper 8.5, the cable enters the next stage.

[0048] After the cable head comes out of the feeding device 7, it passes through the first caliper 8.1 to measure the diameter data. The diameter data is obtained 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 material and can be slightly deformed, which will not cause the cable to be unable to pass). The two conveying rollers 8.2.1 rotate relative to each other, driving the cable into the relevant device to provide power for the advancement of the cable. After the dog tooth straightener 8.3 receives the data from the first caliper 8.1, the spacing of the dog tooth straightener 8. is adjusted to the distance of the cable external square. After the cable head enters, multiple dog tooth rollers 8.3.4 confine it to a square area and force the cable to become straight. Here, the inner core of the cable is made of metal material with strong plasticity. The metal core 5 has become straight, and the outer skin 1, armor layer 2, filling layer 3 and insulation layer 4 will still maintain the original curvature trend. After passing through the dog-tooth straightener 8.3, the cable enters the second transmission mechanism 8.4. The second transmission mechanism 8.4 also obtains the data of the first caliper 8.1, adjusts the distance between the two conveying rollers 8.2.1, and the rotation of the second transmission mechanism 8.4 drives the cable to continue to move forward (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, and on the other hand, the superposition of the two transmission mechanisms can provide the power for the cable to move forward). After passing through the second transmission mechanism 8.4, the second caliper 8.5 measures the diameter information of the cable again. On the one hand, it makes the data more accurate. On the other hand, when the tail of the cable has passed through the first caliper 8.1, although the remaining part is still being transported forward in the first transmission mechanism 8.2 and the dog-tooth straightener 8.3, the first caliper 8.1 can no longer measure the cable diameter data. The cable diameter data measured by the second caliper 8.5 provides a basis for the adjustment of the dog-tooth straightener 8.3 and the second transmission mechanism 8.4.

[0049] like Fig. 20 and Fig.21 As shown, the primary stripping and cutting separation device 9 comprises a primary stripping and cutting separation device base 9.6 and an outer skin cutting mechanism 9.1, an armor layer cutting mechanism 9.2, a cable cutting mechanism 9.3 and an outer layer separation mechanism 9.4 which are arranged from left to right. Fig. 22As shown, 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 transmission direction in the middle of 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 cutting 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 cable outer skin 1 and the armor layer 2 to fall after separation. There is a through groove perpendicular to the cable transmission direction at the end of the upper surface of the base 9.6 of the initial stripping and cutting separation device, which is the second rack hole 9.10, which is used to install the second rack 10.1.6 at the bottom of the cutting mechanism 10.1 on the left and right sides of the filling layer. The first rack hole 9.8 and the second rack hole 9.10 enable the rack of the corresponding mechanism to be installed on the lower surface of the primary peeling and truncation separation device base 9.6. A plurality of servo motors are also installed on the lower surface of the primary peeling and truncation separation device base 9.6 to drive the corresponding rack to reciprocate.

[0050] The primary stripping and cutting separation device 9 is used to strip the outer sheath 1 of the cable. If the cable is armored, the armor layer 2 can be stripped at the same time. After passing through this part of the device, the cable is cut to a suitable length for easy storage and transportation. At the same time, the stripped outer sheath 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 stripping and classified recycling device 10 can separate the cable filling layer 3 and the insulating layer 4, and recycle the metal core 5 and the filling layer 3 and the insulating layer 4 of the cable core respectively. One machine achieves the classified recycling of different components of various types and sizes of cables such as single-core, multi-core, armored and unarmored.

[0051] The primary stripping and cutting separation device 9 has the function of stripping the cable sheath 1 and cutting it according to the predetermined length. The cable first passes through the sheath cutting mechanism 9.1, which includes two sheath cutting rollers 9.1.1 equipped with sheath rotary cutting knives 9.1.2. The rest of the structure is similar to the transmission mechanism, including double-headed screws that can make the sheath cutting rollers 9.1.1 move towards or away from each other at the same time and a servo motor that controls the movement of the double-headed screws, except that there is a line in the middle of the sheath cutting rollers 9.1.1. Fig.23 The circular outer skin rotary cutting knife 9.1.2 shown in the figure, the upper and lower sets of outer skin cutting rollers 9.1.1 are adjusted to the spacing corresponding to the cable diameter according to the data of the two caliper gauges in the previous step, and the spacing between the two sets 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 to expose the internal structure of the cable, and the two outer skin rotary cutting knives 9.1.2 cut the upper and lower parts of the cable respectively, so that the outer skin 1 is cut into two halves.

[0052] If the cable has an armor layer 2, the outer skin 1 and the armor layer 2 will be partially adhered, so that the outer skin 1 cannot be smoothly removed. At this time, after passing through the outer skin cutting mechanism 9.1, the armor layer 2 at the blade 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 skin cutting mechanism 9.1, except that the outer skin rotary cutting knife 9.1.2 is replaced with a serrated armor layer cutting knife that can cut the armor layer 2. The armor layer cutting knife cuts out along the outer skin rotary cutting knife 9.1.2. The blade continues to cut the armor layer 2 inward. The rotation speed of the armor layer cutting knife is faster than that of the outer skin rotary cutting knife 9.1.2, and a speed difference is generated between the two. The forward speed of the cable is the linear speed of the outer edge of the outer skin rotary cutting knife 9.1.2, and the linear speed of the armor layer cutting knife is faster than the forward speed of the cable. This causes the armor layer cutting knife to have a faster rotation speed relative to the cable. At this time, the serrated blade produces a cutting effect similar to that of an angle grinder (like an angle grinder equipped with a hacksaw blade cuts metal), which can effectively cut the armor layer 2.

[0053] The cable cutting mechanism 9.3 is used to cut the cable. The mechanism cuts the corresponding length of the cable according to the demand without affecting the forward movement of the cable. The cutting of the cable is helpful for the subsequent classification and recycling of the cables. Fig.24As shown, it is a device for cutting cables, which can reciprocate and keep 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, and the two cutting knives 9.3.2 are controlled by two sets of cutting push rods 9.3.1 respectively. The cutting knives 9.3.2 and the cutting push rods 9.3.1 are installed inside the frame 9.3.5. There are two slide rails 9.3.3 at the bottom of the frame 9.3.5. The first rack 9.3.4 is installed in the middle of the bottom of the frame 9.3.5. The first rack 9.3.4 cooperates with the servo motor and the gear, so that the frame 9.3.5 can move forward and backward on the slide rail 9.3.3 to realize the parallel reciprocating motion of the cable cutting mechanism 9.3. There is a speed meter 9.5 in front of the cable cutting mechanism 9.3, which can accurately measure the speed of the cable. The cable cutting mechanism 9.3 starts to move according to the speed. According to the predetermined truncation length, after reaching the truncation point, the frame 9.3.5 moves in the same direction and speed with 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 each other at the center of the cable circle, and the cable is cut off. The reciprocating motion direction of the frame 9.3.5 is in the same direction as the moving direction of the cable. When cutting is required, the first rack 9.3.4 at the bottom of the frame 9.3.5 is driven by the servo motor to drive the frame 9.3.5 and its accessories to move in the same direction and speed as the cable. The two remain relatively still. During the movement, the cutting knife 9.3.2 cuts down, the cable is cut off, the cutting knife 9.3.2 is retracted, and the frame 9.3.5 returns to its original position. This ensures that the cable will not be affected when cutting the cable on the assembly line. The cutting knife 9.3.2 includes a central blade and a blade frame located on the blade, left and right sides. When two cutting knives 9.3.2 touch each other, the two blade frames will touch each other, which will not cause excessive contact between the blades, thereby protecting the blades and improving the cutting force of the entire cutting knife 9.3.2.

[0054] After passing through the cable cutting mechanism 9.3, the cable is transported to the outer layer separation mechanism 9.4, which is used to separate the outer skin 1 and the armor layer 2 of the cable. After the outer skin cutting and the armor layer cutting, the outer layer of the cable is cut open, but there is a situation where it is adhered to the internal structure part. The structural composition of the outer layer separation mechanism 9.4 is similar to that of the first transmission mechanism 8.2, but the arrangement method is different. Fig.21It can be seen that the two conveying rollers 8.2.1 are arranged crosswise up and down, and the two form 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, the upper and lower conveying rollers 8.2.1 twist the outer skin 1 and the armor layer 2 to the left and right front respectively at the position of the cable blade. The two conveying rollers 8.2.1 twist respectively to continuously separate the outer skin 1 and the armor layer 2 from the filling layer 3. As for the core of the cable, since the two conveying rollers 8.2.1 move to the left and right front respectively, the oblique forces on the core cancel each other out, and the core continues to move forward. The outer skin 1 and the armor layer 2 are peeled off and fall into the leakage port 9.11 of the base 9.6 of the primary peeling and cutting separation device.

[0055] The secondary peeling and classification recovery device 10 includes: Fig. 20 , Fig.21 , Fig.25 , Fig.26 The filling layer left and right side cutting mechanism 10.1 shown and Fig. 27 , Fig.28 The shown filling layer upper and lower side cutting mechanism 10.2, insulation layer cutting mechanism 10.3, insulation layer separation mechanism 10.4, secondary stripping and classification recovery device base 10.5, terminal transmission mechanism 10.6 and material receiving slope 10.7.

[0056] like Fig.25 and Fig.26As shown, the left and right side cutting mechanism 10.1 of the filling layer is used for cutting the left and right sides of the filling layer 3 in the horizontal direction, and the mechanism comprises a pair of filling layer side cutting rollers 10.1.2 rotatably mounted at the end of the base 9.6 of the primary stripping and cutting and separating device, three unpowered rotary cutting knives coated on the outside of the filling layer side cutting rollers 10.1.2, a baffle plate 10.1.1 mounted on the outside of the filling layer side cutting rollers 10.1.2, a slider 10.1.4 driving the baffle plate 10.1.1 to move, a slide groove 10.1.3 providing a moving track for the slider 10.1.4, a second rack 10.1.6 and a driving gear and a motor. The mechanism has the functions of cutting the left and right sides of the filling layer 3, limiting the left and right movement of the cable and blocking the passage of the outer skin 1. Two second racks 10.1.6 are installed in the second rack hole 9.10 at the end of the base 9.6 of the primary stripping and cutting separation device. The second racks 10.1.6 pass through the slide 10.1.3 upwards and are installed on the lower surface of the slider 10.1.4. The upper surface of the slide 10.1.3 has an inverted trapezoidal notch for accommodating the slider 10.1.4 at the bottom of the filling layer side cutting roller 10.1.2 and enabling the slider 10.1.4 to move in a directional manner in the slide 10.1.3. The second rack 10.1.6 cooperates with the two motors installed on the slide 10.1.3. The motor can drive the second rack 10.1.6 to move horizontally through the driving gear, and then drive the two filling layer side cutting rollers 10.1.2 in linkage, so that the two filling layer side cutting rollers 10.1.2 move toward the middle at the same time, so that the filling layer side cutting rollers 10.1.2 clamp the cable. The upper surface of the slider 10.1.4 is connected with a square boss, namely the baffle directional block 10.1.5. 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. The baffle directional block 10.1.5 is installed with a roller shaft for installing the filling layer side cutting roller 10.1.2. The filling layer side cutting roller 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 relative to each other under the drive of the servo motor to clamp the cable. Three non-powered rotary cutting knives are installed on the filling layer side cutting roller 10.1.2 to cut the filling layer 3 on the left and right sides of the cable. After the cable passes through, several knife edges will be cut on the left and right sides of the filling layer 3. The baffle 10.1.1 is connected to the roller shaft at the top and to the baffle directional block 10.1.5 at the bottom, and is used to block the outer skin 1 and armor layer 2 separated in the previous link, prevent the outer skin 1 and armor layer 2 from entering the subsequent link, and realize the classification of cable dismantling materials.

[0057] The filling layer side cutting roller 10.1.2 itself has no power, and is driven to rotate by the advancement of the cable, and the cable drives it to rotate while being cut.

[0058] like Fig.29 As shown, there are two integrated brackets 10.5.2 on the base 10.5 of the secondary peeling and classification recovery device, and a material receiving port 10.5.1 is arranged below the integrated bracket 10.5.2 for receiving the separated insulating layer 4 and the filling layer 3.

[0059] The filling layer upper and lower side cutting mechanism 10.2 has the same function as the filling layer left and right side cutting mechanism 10.1, both of which 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 powered rotary cutters arranged symmetrically up and down, which cut the filling layer 3 of the upper and lower parts of the cable into multiple parts. Since the filling layers 3 on the left and right sides of the cable have been cut, the filling layers 3 of the cable circumference are cut after passing through the mechanism. Under the extrusion of the two cutting rollers in the filling layer upper and lower side cutting mechanism 10.2, the filling layer 3 and the cable core are separated, and at the same time, the different cable cores of the multi-core cable are also squeezed 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 is rigid and maintains a straight state. The filling layer 3 has material memory and becomes an arc after being cut, so it is automatically separated 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.

[0060] The insulating layer cutting mechanism 10.3 is located in the next process of the upper and lower side cutting mechanism 10.2 of the filling layer. Its overall structure is similar to the first transmission mechanism 8.2, except that the roller here becomes a dense-tooth cutting roller, which is used to cut the insulating layer 4 of multiple cable cores. When multiple cable cores pass through here, they are squeezed and arranged side by side. The surface of the dense-tooth cutting roller is densely covered with circular cutters, which can cut the insulating layer 4 of multiple cables on the one hand. At the same time, the cutters are arranged in parallel, and there is a certain distance between the two cutters, which is smaller than the diameter of the cable core. When the core of the cable passes through, it passes between the two cutters, and the insulation on both sides is cut off. The metal core can maintain positive motion under the action of the two cutters to ensure the forward direction of the cable core. The dense-tooth cutting rollers are also arranged in two groups symmetrically in the upper and lower parts, and the control method is the same as that of the first transmission mechanism 8.2, except that the distance between the upper and lower groups of dense-tooth cutting rollers is closer than the distance between the two conveying rollers 8.2.1 in the first transmission mechanism 8.2. This is because the cable core diameter is smaller than the diameter of the entire cable, and the cable cores are arranged side by side, and their height is smaller than the height of the entire cable.

[0061] The insulating layer separation 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 separation mechanism 9.4. The two X-shaped conveying rollers 8.2.1 twist the metal core 5 to separate the outer insulating layer 4, so that the insulating layer 4 is separated from the metal core 5. The insulating layer 4 is relatively soft and will fall off the metal core 5 and fall into the receiving port 10.5.1 below. A basket or conveyor belt is placed below the receiving port 10.5.1 to collect the insulating layer 4 separately. A basket or conveyor belt can also be placed below the initial stripping and cutting separation device 9 to realize the classified collection of the outer skin 1 and the armor layer 2.

[0062] After the insulation layer 4 is stripped off, only the metal core 5 is left. 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. Because the cable has been cut into a set length in the cable cutting mechanism 9.3, the metal core 5 of the cable will fall off and slide down the receiving slope 10.7 after this section is completed.

[0063] The metal core 5 has strong plasticity. During the cable straightening process, external force is used to straighten the metal core 5. In a short period of time, the outer filling layer 3, outer skin 1 and other materials will maintain their original shapes, and will automatically curl up when subsequently peeled off. This is a point that the present invention should focus on in the cable recycling process.

[0064] The above content is an overall introduction to the equipment and the working process of the equipment when disassembling and recycling multi-core armored cables. For other types of cables, there are the following types of working processes: 1. If the cable is single-core and unarmored: The outer layer separation mechanism 9.4 separates the outer sheath 1 cut off by the outer sheath cutting mechanism 9.1 from the cable core, and the armor layer cutting mechanism 9.2 does not work. The two sets of armor layer cutting knives move to the top and bottom of the double-headed screw under the control of the double-headed screw, and the armor layer cutting knives do not touch the cable. The left and right side cutting mechanisms 10.1 of the filling layer in the secondary stripping and classification recovery device 10 are only used for limiting, and the following mechanisms do not work and are only used to transport the cable core to the receiving slope 10.7. Various rollers are only used for transportation and not for compaction.

[0065] 2. If the cable is single-core armored: The working sequence is roughly the same as the first type of working process, the only difference is that the armor layer cutting mechanism 9.3 will work to cut the armor layer 2.

[0066] 3. If the cable is multi-core and unarmored: The working sequence is roughly the same as the first type of working process, except that all parts of the secondary peeling and classification recovery device 10 are working.

[0067] 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 may have various modifications and variations. 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.
