Description

Technical Field

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

[0002] Cable is a general term for items such as optical cables and electrical cables. It is mainly used for multiple functions such as controlling installation, connecting equipment, and transmitting electricity. It is usually composed of one or more insulated cores, which may have a coating, a total protective layer and an outer sheath.

[0003] Existing cable recycling equipment often finds it difficult to achieve efficient and thorough separation and recycling when dealing with these complex components, and has obvious deficiencies in intelligent control. Some cable recycling equipment has a low degree of automation and requires manual participation in many links, which not only increases labor costs.

[0011] Preferably, the drum mechanism includes a drum outer wall, which is fixedly connected to one side of the rotating shaft three, a magnetic attraction ring is present on the inner wall of the drum, a collision block and an ultrasonic sensor two are fixedly connected to the inner wall of the drum, a hydraulic cylinder two is fixedly connected to the drum bottom plate, the uppermost layer of the hydraulic cylinder two is enlarged and thickened, a collision bar is fixedly connected to the outer side of the hydraulic cylinder two, a hydraulic press two is fixedly connected to the hydraulic cylinder two, a collecting pipe is fixedly connected to the inner wall of the drum, a hydraulic cylinder three is fixedly connected to the collecting pipe, the hydraulic cylinder three is an annular hydraulic cylinder, the hydraulic cylinder three can drive the collecting pipe to extend and retract, and the drum inner wall of the drum mechanism is connected to the drum outer wall. A magnetic attraction ring is arranged at the position of the collecting pipe between the walls, so that the collecting pipe on the outer wall of the drum can overlap with the collecting pipe on the inner wall of the drum after the drum stops rotating. One side of the hydraulic cylinder three is fixedly connected to the hydraulic press three, one side of the collecting pipe is fixedly connected to the collecting pump, the collecting pipe is fixedly connected to the collecting pipe solenoid valve, the collecting pump is fixedly connected to the discharge pipe, the discharge pipe is fixedly connected to the discharge pipe solenoid valve, a second fixed platform is fixedly connected below the collecting pump, a motor six and a vibrator are fixedly connected below the second fixed platform, a partition is fixedly connected inside the drum mechanism, and a sieve hole is fixedly connected on the partition.

[0012] Preferably, the control system controls the operation and running process of the motors and hydraulic presses on the cutting mechanism, the gear rotating mechanism and the roller mechanism.

[0013] Preferably, the actual distance between the cable and the cutter is calculated according to the thickness of the cable, and the cable is cut longitudinally and circularly on three sides, specifically:

[0014] When the cable enters the cable recycling equipment from the cable inlet on the bracket, the ultrasonic sensor detects the presence of the metal layer and the position of the conductor of the recycled cable, detects the boundary between the metal and non-metal inside the cable through the electromagnetic induction sensor, and calculates the distance between the cutting knife and the cable through the ultrasonic distance formula:

[0015]

[0016] L: represents the distance between the tool and the cable;

[0017] t: represents the time from when the ultrasonic wave is sent to when it is returned and received;

[0018] C: represents the propagation speed of ultrasound;

[0019] This is used to calculate the distance between the cutting knife and the cable, and the actual moving distance of the hydraulic cylinder is calculated using the following formula:

[0020]

[0028] The control system injects hydraulic oil into the hydraulic cylinder according to the result calculated by the above formula, and the hydraulic press controls the movement of the hydraulic cylinder. After moving the specified distance, the control system controls motor one to work, driving shaft one to rotate, the rotation of shaft one drives the bevel gear to rotate, and the rotation of the bevel gear drives the cable to move forward. At this time, the control system controls motor two to work and drive shaft two to rotate. The rotation of shaft two drives the cutting knife to rotate and cut the cable. The cutting knife makes longitudinal cuts on the cable on three sides, and cuts the cable into pieces by circular cutting after the longitudinal cutting is completed. The cut cables fall into the feed hopper and accumulate in the feed hopper. At the same time, the control system controls the infrared sensor to monitor the accumulation of cables in the feed hopper in real time.

[0029] Preferably, the metal and non-metal materials in the cable are separated, specifically:

[0030] When the second ultrasonic sensor detects that the separation degree of metal and non-metal reaches F1, the metal and non-metal in the cable have been initially separated during the process of rotation, vibration and collision, and the metal and non-metal begin to accumulate according to the material density under the action of centrifugal force. The metal material with higher density approaches the inner wall of the drum under the action of centrifugal force, and the metal iron therein is adsorbed on the inner wall of the drum by the magnetic suction ring on the inner wall of the drum. The copper and aluminum metals are scattered around the inner wall of the drum, and the non-metal plastics and rubbers are concentrated near the second hydraulic cylinder under the action of centrifugal force. At this time, the control system controls the second hydraulic press to inject hydraulic oil into the second hydraulic cylinder, and the second hydraulic cylinder begins to extend upward, exposing a hole in the center area of ​​the partition. The non-metal plastics and rubber begin to fall from the hole of the partition into the bottom plate of the drum under the action of centrifugal force and vibration of the vibrator. At the same time, the second ultrasonic sensor monitors the separation degree of metal and non-metal in real time;

[0031] When ultrasonic sensor 2 detects that the separation degree of metal and non-metal reaches F2, the metal and non-metal in the cable have been basically completely separated during the process of rotation, vibration and collision. The metal iron is adsorbed on the magnetic suction ring on the inner wall of the drum, and the metal copper and aluminum are accumulated around the inner wall of the drum under the action of centrifugal force. The non-metallic plastic and rubber fall from the central hole of the partition to the bottom plate of the drum under the action of centrifugal force. At this time, the control system controls the hydraulic cylinder 2 to retract inward until the hole on the partition is blocked. When the hole on the partition is blocked, the control system controls the motor 6 to stop working, and the drum starts to stop rotating slowly. When the drum stops rotating, the vibrator continues to work to deposit on the partition and the bottom plate of the drum. The metal and non-metal on the drum oscillate. During the oscillation process, the debris accumulated on the metal falls into the drum bottom plate from the sieve holes on the partition. At this time, the control system controls the hydraulic press three to start working and pushes the hydraulic cylinder three to drive the collection tube to extend to the inner wall of the drum and dock with the collection tube on the inner wall of the drum. After the docking is completed, the control system controls the collection pump to start working, open the collection tube solenoid valve, and use the negative ion adsorption force generated by the collection pump to collect the non-metallic plastic, rubber and debris on the drum bottom plate into the collection pump. When the ultrasonic sensor two detects that the plastic, rubber and debris on the drum bottom plate have been collected, the collection pump is controlled to stop working, and the control system controls the hydraulic press three to retract the hydraulic cylinder three and close the collection tube solenoid valve.

[0032] (II) Beneficial effects

[0033] The present invention determines the thickness and level of the cable through the sensor on the cutting mechanism, and adjusts the extension length of the cutting knife according to the detection result, and performs longitudinal and transverse cutting on the cable. The cut cable is subjected to preliminary layered separation of metal and non-metal in the drum mechanism. The infrared sensor accurately determines the cable accumulation amount, and the ultrasonic sensor monitors the metal and non-metal separation process in real time. The multi-level separation mechanism in the drum mechanism, such as rotation, shaking, multiple collisions and magnetic attraction, plus the secondary screening of the water pool, performs classified recycling, which improves the recycling efficiency and quality, reduces the processing cost and environmental pollution, and reduces the loss caused by human participation.

[0052] The control system controls the work and operation process of the motors and hydraulic presses on the cutting mechanism 2, the gear rotating mechanism 3 and the roller mechanism 4.

[0053] Embodiment 2, based on embodiment 1, a preferred embodiment of a cable recovery device provided by the present invention is as follows: Figures 1 to 7As shown: a cable recycling device, the control system controls the ultrasonic sensor 203 to detect the existence of the metal layer and the position of the conductor of the recycled cable, detects the boundary between the metal and non-metal inside the cable through the electromagnetic induction sensor 214, and controls the hydraulic press 207 to drive the hydraulic cylinder 208 to push forward, so that the cutting knife 212 performs longitudinal cutting on three sides of the cable, and then performs circular cutting after longitudinal cutting, cuts the cable and separates the cable through the rotating vibration of the roller mechanism 4, and drives the roller mechanism 4 to rotate as a whole through the gear rotating mechanism 3 to dump the metal material into the water pool, and the collection pump 408 discharges the non-metal material and metal debris into the water pool through the discharge pipe 411 for secondary classification of metal and non-metal;

[0054] The infrared sensor 219 detects that the stacking range of the feed hopper 215 is H1 and H2, where H1 represents that the cables have not yet reached the preset stacking amount for separation of metal and non-metal, and need to continue to be stacked; H2 represents that the stacking degree of the cables has reached the set separation stacking amount;

[0055] The separation degree of metal and non-metal in the roller mechanism 4 detected by the second ultrasonic sensor 405 is in the range of F1 and F2, where F1 represents that the separation of metal and non-metal in the cable reaches a certain degree, and the positions in the roller mechanism 4 begin to be divided according to the density during rotation; F2 represents that the metal and non-metal in the cable are divided according to the density during rotation, and the metal with high density surrounds the roller mechanism 4, and the non-metal with low density surrounds the middle position of the roller mechanism 4;

[0056] The actual distance between the cable and the cutter is calculated based on the cable thickness, and the cable is cut longitudinally and circularly on three sides. Specifically:

[0057] When the cable enters the cable recovery device from the cable inlet 202 on the bracket 201, the ultrasonic sensor 203 detects the presence of the metal layer and the position of the conductor of the recovered cable, and detects the boundary between the metal and non-metal inside the cable through the electromagnetic induction sensor 214, and calculates the distance between the cutting knife 212 and the cable through the ultrasonic distance formula:

[0058]

[0059] L: represents the distance between the tool and the cable;

[0060] t: represents the time from when the ultrasonic wave is sent to when it is returned and received;

[0061] C: represents the propagation speed of ultrasound;

[0062] In this way, the distance between the cutting blade 212 and the cable is calculated, and the actual moving distance of the hydraulic cylinder 208 is calculated by the following formula:

[0063]

[0064] L: represents the actual moving distance of the hydraulic cylinder;

[0065] D: represents the inner diameter of the hydraulic cylinder;

[0066] d: represents the piston rod diameter;

[0067] v: represents the speed of piston movement;

[0068] f: represents the unit mediation coefficient;

[0069] n v : represents volumetric efficiency;

[0070] n m : Represents mechanical efficiency.

[0071] The control system injects hydraulic oil into the hydraulic cylinder 208 according to the result calculated by the above formula, and the hydraulic press 207 controls the hydraulic cylinder 208 to move. After moving a specified distance, the control system controls the motor 1 204 to work, driving the shaft 1 205 to rotate. The rotation of the shaft 1 205 drives the bevel gear 206 to rotate. The rotation of the bevel gear 206 drives the cable to move forward. At this time, the control system controls the motor 211 to work and drive the shaft 210 to rotate. The rotation of the shaft 210 drives the cutting knife 212 to rotate and cut the cable. The cutting knife 212 performs longitudinal cutting on three sides of the cable, and cuts the cable into pieces by circular cutting after the longitudinal cutting is completed. The cut cables fall into the feed hopper 215 and accumulate in the feed hopper 215. At the same time, the control system controls the infrared sensor 219 to monitor the accumulation of cables in the feed hopper 215 in real time.

[0072] Separate the metal and non-metal materials in the cable, specifically:

[0073] When the control system receives the data H1 transmitted by the infrared sensor 219, the control system determines that the cable has not reached the preset accumulation amount, and the control system does not control the roller mechanism 4, and the roller mechanism 4 does not work;

[0074] When the control system receives the data H2 transmitted by the infrared sensor 219, the control system determines that the cable has reached the preset accumulation amount of metal and non-metal separation and starts separation. Specifically:

[0075] The control system controls the motor three 218 to open the electric valve 217, and the accumulated cables begin to fall from the bottom of the feed hopper 215 into the drum of the drum mechanism 4. The ultrasonic sensor two 405 monitors the falling process of the cables in real time. When the ultrasonic sensor two 405 detects that the cables are no longer falling into the drum mechanism 4, the control system controls the motor three 218 to close the electric valve 217, so that the cables enter the next wire material accumulation process. At the same time, the control system controls the motor six 412 and the vibrator 418 to start working. The motor six 412 drives the inner wall 402 of the drum to start rotating. The vibrator 418 works to make the drum and the partition 414 vibrate. The rotation of the drum causes the cables accumulated on the partition 414 to start rotating in the direction of the inner wall 402 of the drum under the action of centrifugal force and collide with the collision block 403 and the inner wall 402 of the drum. After colliding with the inner wall 402 of the drum and the collision block 403, they rotate and collide with the collision bar 404 installed on the widened and thickened hydraulic cylinder two 416 for a second time. The control system monitors the data of the ultrasonic sensor two 405 in real time. Specifically:

[0076] When the ultrasonic sensor 2 405 detects that the separation degree of metal and non-metal reaches F1, at this time, the metal and non-metal in the cable have been initially separated during the process of rotation, vibration and collision, and the metal and non-metal begin to accumulate according to the material density under the action of centrifugal force. The metal material with higher density approaches the inner wall 402 of the drum under the action of centrifugal force, and the metal iron therein is adsorbed on the inner wall 402 of the drum by the magnetic suction ring on the inner wall 402 of the drum, and the metal of copper and aluminum is scattered around the inner wall 402 of the drum, and the non-metal plastic and rubber are concentrated near the hydraulic cylinder 2 416 under the action of centrifugal force. At this time, the control system controls the hydraulic press 2 413 to inject hydraulic oil into the hydraulic cylinder 2 416, and the hydraulic cylinder 2 416 begins to extend upward, exposing a hole in the central area of ​​the partition 414. The non-metal plastic and rubber begin to fall from the hole of the partition 414 into the bottom plate 417 of the drum under the action of centrifugal force and vibration of the vibrator 418. At the same time, the ultrasonic sensor 2 405 monitors the separation degree of metal and non-metal in real time;

[0077] When the ultrasonic sensor 2 405 detects that the degree of separation of metal and non-metal reaches F2, the metal and non-metal in the cable have been basically completely separated during the process of rotation, vibration and collision. The metal iron is adsorbed on the magnetic attraction ring of the inner wall 402 of the drum, and the metal copper and aluminum are accumulated around the inner wall 402 of the drum under the action of centrifugal force. The non-metallic plastic and rubber fall from the central hole of the partition 414 to the drum bottom plate 417 under the action of centrifugal force. At this time, the control system controls the hydraulic cylinder 2 416 to retract inward until the hole on the partition 414 is blocked. When the hole on the partition 414 is blocked, the control system controls the motor 6 412 to stop working, and the drum starts to slowly stop rotating. After the drum stops rotating, the vibrator 418 continues to work to oscillate the metal and non-metal accumulated on the partition 414 and the drum bottom plate 417 During the oscillation process, the debris accumulated on the metal falls from the sieve hole 415 on the partition 414 into the drum bottom plate 417. At this time, the control system controls the hydraulic press three 419 to start working and push the hydraulic cylinder three 420 to drive the collection pipe 407 to extend to the inner wall 402 of the drum and dock with the collection pipe 407 on the inner wall 402 of the drum. After the docking is completed, the control system controls the collection pump 408 to start working, open the collection pipe solenoid valve 409, and use the negative ion adsorption force generated by the collection pump 408 to collect the non-metallic plastic, rubber and debris on the drum bottom plate 417 into the collection pump 408. When the ultrasonic sensor two 405 detects that the plastic, rubber and debris on the drum bottom plate 417 have been collected, the collection pump 408 is controlled to stop working, and the control system controls the hydraulic press three 419 to retract the hydraulic cylinder three 420 and close the collection pipe solenoid valve 409;

[0078] After the metal and non-metal in the cable are initially screened by layers, the metal and non-metal are further screened by using a water pool. Specifically:

[0079] The control system controls the motor 4 304 to drive the shaft 4 307 to rotate clockwise, the shaft 4 307 rotates to drive the gear 2 303 to rotate, the gear 2 303 rotates to drive the gear chain 301 to rotate, the gear chain 301 rotates to drive the gear 1 302 to move, the gear 1 302 moves through the shaft 3 306 to drive the roller mechanism 4 to move, when the gear 1 302 contacts the gear 2 303, the motor 4 304 is controlled to stop working, and the motor 5 305 is controlled to rotate, the motor 5 305 rotates to drive the shaft 3 306 to rotate The rotation of the rotating shaft 306 drives the drum mechanism 4 to rotate as a whole, and the metal material in the drum is dumped into the water pool. After the metal in the drum is dumped, the control system controls the discharge pipe solenoid valve 410 to open, so that the plastic, rubber and debris in the collection pump 408 are discharged from the discharge pipe 411 into the water pool for secondary screening of metals and non-metals. The density of metal is greater than the density of water, and it will sink to the bottom of the water when it falls into the water. The density of non-metal rubber and plastic is less than the density of water, and it will float on the water surface, thereby completing the secondary screening of metals and non-metals.

[0080] The present invention determines the thickness and level of the cable through the sensor on the cutting mechanism 2, and adjusts the extension length of the cutting knife 212 according to the detection result, and performs longitudinal and transverse cutting on the cable. The cut cable is initially separated into metal and non-metal in the roller mechanism 4. The infrared sensor 219 accurately determines the cable accumulation amount, and the ultrasonic sensor 2405 monitors the metal and non-metal separation process in real time. The multi-level separation mechanism in the roller mechanism 4, such as rotation, shaking, multiple collisions and magnetic attraction, plus the secondary screening of the water pool, performs classified recycling, which improves the recycling efficiency and quality, reduces the processing cost and environmental pollution, and reduces the loss caused by human participation.
