Description

Technical Field

[0001] The present invention relates to the technical field of waste cable recycling, and particularly relates to a control method, system and device for a copper-plastic separation production line of waste cables. Background Art

[0002] With the acceleration of the urbanization process and the continuous improvement of the industrialization level, cables, as important media for power transmission and information transmission, have been widely used in various infrastructure construction and industrial production. With the increase in the service life of cables and the replacement of technologies, the quantity of waste cables has also been increasing year by year. Waste cables usually contain non-ferrous metals such as copper and aluminum, as well as insulating materials such as plastics and rubbers, and have high recycling value.

[0003] To achieve the recycling of resources and environmental protection, it is particularly important to scientifically and efficiently recycle waste cables. Currently, the recycling methods of waste cables mainly include steps such as manual sorting, mechanical crushing, and specific gravity separation, and the effective separation of metal and non-metal materials in the cables is realized to achieve the reuse of resources.

[0004] For example, a waste cable recycling device disclosed in a Chinese invention patent with the publication number of CN117153497B includes: a base, a peeling chamber is formed in the base, a guiding pipe is welded on the outer wall of the base, the guiding pipe extends into the peeling chamber, a mounting frame is welded on the outer wall of the guiding pipe, and a pair of tool holders are slidably inserted into the mounting frame.

[0005] For example, a waste cable recycling device disclosed in a Chinese invention patent with the publication number of CN117809915B includes: a feeding trough, one side is the feeding side; a bearing plate, horizontally arranged on the feeding side of the feeding trough; a reciprocating conveying member, including a first part located outside the feeding side of the feeding trough and a second part located below the bearing plate, a drag plate, arranged on the reciprocating conveying member, rotates with the reciprocating conveying member, and can drive the drag plate to reciprocate between the first part and the second part; a plurality of hook plates, arranged on the drag plate, and the hook plates can pass through the feeding trough and the bearing plate along with the movement of the drag plate; a pressing plate, movably arranged above the bearing plate along the direction perpendicular to the surface of the bearing plate; a cutting knife, fixed on the pressing plate, and along with the movement of the pressing plate, the cutting knife can cut off the cable on the upper side of the bearing plate.

[0006] The above technologies have at least the following technical problems: Current waste cable recycling methods mostly focus on the mechanical design of a single crushing process, the crushing operation with fixed parameters, and the extensive sorting operation, ignoring the dynamic matching of the particle size distribution throughout the process. This easily leads to problems such as fluctuations in the sorting load caused by uneven upstream crushing particle sizes, copper-plastic adhesion residues caused by unstable crushing effects, or material accumulation or interruption caused by the mismatch between the logistics conveying rhythm and the equipment processing capacity, resulting in a decrease in the purity of copper rice, a low plastic recovery rate, increased equipment wear, and a reduction in overall production capacity.

[0041] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0042] Refer to Figure 1 As shown, the first aspect of the present invention provides a control method for a copper-plastic separation production line of waste cables, including the following steps: Refer to Figure 6 As shown, it is the shredder monitoring interface of the composite wire and cable recycling control system involved in the embodiment of the present application, from which the coarse particle ratio after the cable is shredded and the adjustment records of the shredder can be detected.

[0043] S1, the shredder receives waste cables for cable shredding, performs particle size distribution identification, and adaptively adjusts the shredder feeding device based on the particle size distribution identification result.

[0044] In this embodiment, the specific analysis method of the particle size distribution identification result is as follows: Perform particle size distribution identification to obtain the particle size data of the shredded waste cables.

[0045] The particle size data of the shredded waste cables includes the maximum particle size, average particle size, coarse particle ratio, and particle size standard deviation of the shredded waste cables.

[0046] The particle size data of shredded waste cables is collected through an industrial camera installed above the discharge port of the shredder and then obtained through analysis using an image analysis algorithm. In a specific embodiment, the image analysis algorithm can be OpenCV.

[0047] It should be noted that the coarse particle ratio refers to the proportion of particles with a particle size larger than the system-set particle size threshold in the total number of particles in the shredded waste cable material.

[0048] It should be understood that the maximum particle size directly affects the coarse particle ratio. Because when there are extremely large particles in the discharge, the proportion of coarse particles increases. The average particle size reflects the overall fineness of crushing and is usually positively correlated with the coarse particle ratio, that is, a high coarse particle ratio means a large average particle size. And the standard deviation of particle size measures the consistency of the particle size distribution. If the coarse particle ratio increases or the particle size span widens, the standard deviation also increases.

[0049] Extract the reference maximum particle size, reference average particle size, reference coarse particle ratio, and reference particle size standard deviation stored in the database.

[0050] It should be noted that the database is used to store the parameters related to the recycling control system of the waste cable recycling production line.

[0051] Extract the particle size maximum value particle size distribution coefficient, average particle size particle size distribution coefficient, coarse particle ratio particle size distribution coefficient, and particle size standard deviation particle size distribution coefficient preset in the database.

[0052] It should be noted that the value ranges of the particle size maximum value particle size distribution coefficient, average particle size particle size distribution coefficient, coarse particle ratio particle size distribution coefficient, and particle size standard deviation particle size distribution coefficient are all between 0 and 1, and the sum of the particle size maximum value particle size distribution coefficient, average particle size particle size distribution coefficient, coarse particle ratio particle size distribution coefficient, and particle size standard deviation particle size distribution coefficient is 1. When in use, the pre-set values can be directly extracted from the database. For example, the specific extraction method is to construct a one-to-one mapping set between the maximum particle size, average particle size, coarse particle ratio, and particle size standard deviation and the corresponding particle size maximum value particle size distribution coefficient, average particle size particle size distribution coefficient, coarse particle ratio particle size distribution coefficient, and particle size standard deviation particle size distribution coefficient respectively. When in use, the obtained maximum particle size, average particle size, coarse particle ratio, and particle size standard deviation are respectively input into the corresponding mapping sets to extract the particle size maximum value particle size distribution coefficient, average particle size particle size distribution coefficient, coarse particle ratio particle size distribution coefficient, and particle size standard deviation particle size distribution coefficient.

[0053] Characterize the particle size distribution of shredded waste cables based on the particle size data of shredded waste cables.

[0054] The particle size distribution characterization parameter for shredding waste cables is a quantitative index of the combined influence degree of the maximum particle size, average particle size, coarse particle ratio, and particle size standard deviation of the shredded waste cables on the shredding effect. The specific analysis process is as follows: The maximum particle size, average particle size, coarse particle ratio, and particle size standard deviation are respectively compared with the corresponding reference values, and the results of each comparison are coupled with the corresponding particle size distribution coefficient to obtain the particle size distribution characterization parameter of the shredded waste cables.

[0055] In a specific embodiment, the particle size distribution characterization parameter of the shredded waste cables is specifically represented as follows: , wherein, is the particle size distribution characterization parameter of the shredded waste cables, is the maximum particle size, is the average particle size, is the coarse particle ratio, is the particle size standard deviation, is the reference maximum particle size, is the reference average particle size, is the reference coarse particle ratio, is the reference particle size standard deviation, is the particle size distribution coefficient of the maximum particle size, is the particle size distribution coefficient of the average particle size, is the particle size distribution coefficient of the coarse particle ratio, is the particle size distribution coefficient of the particle size standard deviation.

[0056] The particle size distribution characterization parameter of the shredded waste cables is used as the particle size distribution recognition result.

[0057] In this embodiment, the adaptive adjustment of the pusher device of the shredder is carried out, and the specific analysis process is as follows: Extract the preset coarse particle ratio threshold in the database.

[0058] If the coarse particle ratio is greater than or equal to the coarse particle ratio threshold, the subsequent waste cable treatment process is not executed, and a warning prompt message is generated synchronously.

[0059] If the coarse particle ratio is greater than or equal to the coarse particle ratio threshold, it means that when the coarse particle ratio in the shredded cable exceeds the acceptable range set by the system, it indicates that there are a large number of oversized fragments, which may cause jamming, abnormal load, or decreased sorting efficiency of the subsequent crusher. At this time, the system automatically aborts the process to prevent unqualified materials from entering the next stage, and at the same time issues a warning prompt to prompt the operator to detect the shredder.

[0060] Extract the preset particle size distribution characterization threshold in the database.

[0061] If the particle size distribution characterization parameter of shredded waste cables is less than the particle size distribution characterization threshold and the coarse particle ratio is less than the coarse particle ratio threshold, no adaptive adjustment is performed on the pusher device of the shredder.

[0062] If the particle size distribution characterization parameter of shredded waste cables is less than the particle size distribution characterization threshold and the coarse particle ratio is less than the coarse particle ratio threshold, it indicates that not only is the overall particle size distribution of the shredded cable particles concentrated (with a small standard deviation), but also the content of large particles is controlled within an acceptable range, indicating that the shredding effect is good and uniform, and there is no need to further intervene in the feeding rhythm. Maintaining the current feeding rate of the shredder can meet the requirements of subsequent processing.

[0063] If the particle size distribution characterization parameter of shredded waste cables is greater than or equal to the particle size distribution characterization threshold and the coarse particle ratio is less than the coarse particle ratio threshold, then a difference operation is performed on the particle size distribution characterization parameter of shredded waste cables and the particle size distribution characterization threshold to obtain the first deviation parameter of the particle size distribution of shredded waste cables.

[0064] If the particle size distribution characterization parameter of shredded waste cables is greater than or equal to the particle size distribution characterization threshold and the coarse particle ratio is less than the coarse particle ratio threshold, it indicates that although the coarse particle ratio has not reached an abnormal level, the particle size distribution is relatively dispersed, and there are problems such as uneven feeding rhythm and overly rapid pushing. By adjusting the pushing speed, the shredding consistency can be improved, making the discharged particle size more concentrated and facilitating the stable operation of subsequent pulverization.

[0065] It should be noted that the difference operation refers to subtracting the particle size distribution characterization threshold from the particle size distribution characterization parameter of shredded waste cables.

[0066] Extract the pushing speed adjustment values corresponding to the intervals of the first deviation parameters of the particle size distribution of each shredded waste cable stored in the database, and map and extract the pushing speed adjustment value corresponding to the interval in which the first deviation parameter of the particle size distribution of the shredded waste cable is located, which is denoted as the pushing speed adjustment value of the pusher device of the shredder.

[0067] It should be noted that the larger the first deviation parameter of the particle size distribution of shredded waste cables, the more uneven the particle size distribution of the shredded material and the worse the shredding consistency. At this time, to improve the shredding quality and promote particle concentration, the system should actively reduce the pushing speed. Therefore, the mapped pushing speed adjustment value is negative, and the larger the absolute value, the more significantly the pushing rhythm should be slowed down.

[0068] Obtain the current pushing speed of the pusher device of the shredder, and perform adaptive adjustment on the pusher device of the shredder in combination with the pushing speed adjustment value of the pusher device of the shredder, that is, use the sum of the current pushing speed and the pushing speed adjustment value as the pushing speed for the pusher device of the shredder to execute.

[0069] Refer to Figure 4As shown in the figure, it is a flowchart of the adaptive adjustment of the working parameters of the cable shredder involved in the embodiment of the present application. First, the initial working parameters of the shredder are set, and then the shredding is performed and the evaluation data is collected. After analyzing the shredding effect score, the correction coefficient is extracted to calculate the corrected score, and then the corresponding adjustment parameter set is matched according to the score deviation, and finally the adaptive adjustment of the shredder parameters is realized, so as to optimize the shredding effect.

[0070] Refer to Figure 7 As shown in the figure, it is the shredder monitoring interface of the composite wire and cable recycling control system involved in the embodiment of the present application, from which the load current when the shredder executes the cable shredding process and the shredder adjustment record can be monitored.

[0071] S2, convey the shredded waste cable to the cable shredder, set the initial working parameters of the cable shredder according to the particle size distribution recognition result, analyze the shredding effect score of the waste cable, and perform the adaptive adjustment of the working parameters of the cable shredder in combination with the particle size distribution recognition result.

[0072] In this embodiment, setting the initial working parameters of the cable shredder according to the particle size distribution recognition result is specifically as follows: If the adaptive adjustment of the shredder pusher device is not performed, the particle size distribution characterization parameter of the shredded waste cable is recorded as the second particle size distribution characterization parameter of the shredded waste cable.

[0073] If the adaptive adjustment of the shredder pusher device is performed, after the adjustment is completed, the particle size distribution characterization parameter of the shredded waste cable is obtained again, and the particle size distribution characterization parameter of the shredded waste cable obtained again is recorded as the second particle size distribution characterization parameter of the shredded waste cable.

[0074] It should be noted that if the particle size distribution characterization parameter of the shredded waste cable obtained again is still greater than or equal to the particle size distribution characterization threshold, it means that the current adjustment is invalid, and a warning prompt message is generated to terminate the subsequent process.

[0075] The second particle size distribution characterization parameter of the shredded waste cable is used as the particle size distribution recognition result.

[0076] Obtain the second particle size distribution characterization deviation parameter of the shredded waste cable, that is, the numerical result of subtracting the second particle size distribution characterization parameter of the shredded waste cable from the particle size distribution characterization threshold is used as the second particle size distribution characterization deviation parameter of the shredded waste cable.

[0077] Extract the set of initial working parameter settings of the shredder corresponding to the interval of the second particle size distribution characterization deviation parameter of each shredded waste cable stored in the database, and map and extract the set of initial working parameter settings of the shredder corresponding to the interval where the second particle size distribution characterization deviation parameter of the shredded waste cable is located, which is recorded as the set of initial working parameter settings of the cable shredder.

[0078] Initial working parameter setting set for the cable shredder, including the initial setting value of the main shaft speed of the shredder and the initial setting value of the interval duration between the fixed and moving knives of the shredder.

[0079] In this embodiment, the analysis of the crushing effect score of waste cables is as follows: Crush the waste cables with the preset crushing time window in the database and collect the crushing evaluation data.

[0080] The crushing evaluation data includes the average load current, the current fluctuation amplitude, the average value of the discharge particle size, and the metal wire shearing rate.

[0081] It should be noted that the current fluctuation amplitude refers to the difference between the maximum and minimum values of the load current of the shredder within the preset crushing time window, and the metal wire shearing rate refers to the proportion of the number of metal wires effectively sheared into short segments in the total number of metal wires in the crushed material.

[0082] It should be added that effective shearing means that after the metal wire is crushed, its single metal wire is cut into multiple independent line segments with a length not greater than the shearing judgment threshold set in the database, and it does not show the characteristics of linear extension, winding or wire drawing.

[0083] It should be added that the average load current and the current fluctuation amplitude are collected through the system program log, and the average value of the discharge particle size and the metal wire shearing rate are obtained by collecting the particle size images through an industrial camera installed above the discharge conveyor belt of the shredder and analyzing them through an image analysis algorithm. In a specific embodiment, the image analysis algorithm can be OpenCV.

[0084] Extract the reference average load current, reference average load current fluctuation value, reference current fluctuation amplitude, reference average value of the discharge particle size, and reference metal wire shearing rate stored in the database.

[0085] Extract the ideal interval of the average load current preset in the database, and thus obtain the ideal upper limit value and ideal lower limit value of the average load current.

[0086] Extract the distribution factors of the average load current, current fluctuation amplitude, average value of the discharge particle size, and metal wire shearing rate preset in the database.

[0087] It should be noted that the average load current distribution factor, the current fluctuation amplitude distribution factor, the average value distribution factor of the discharge particle size and the metal wire cutting rate distribution factor all have a value range of 0-1, and the sum of the average load current distribution factor, the current fluctuation amplitude distribution factor, the average value distribution factor of the discharge particle size and the metal wire cutting rate distribution factor is 1. When used, the pre-set value can be directly extracted from the database. The specific extraction method is, for example, to construct a one-to-one mapping set with the corresponding average load current distribution factor, current fluctuation amplitude distribution factor, discharge particle size average value distribution factor and metal wire cutting rate distribution factor respectively. When used, the obtained average load current, current fluctuation amplitude, discharge particle size average value distribution factor and metal wire cutting rate are respectively input into the corresponding mapping set, so as to extract the average load current distribution factor, current fluctuation amplitude distribution factor, discharge particle size average value distribution factor and metal wire cutting rate distribution factor.

[0088] Analyze the shredding effect score of waste cables based on the shredding evaluation data.

[0089] The scrap cable pulverization effect score is a quantitative indicator of the degree of influence of the average load current, current fluctuation amplitude, average output particle size and metal wire cutting rate on the scrap cable pulverization effect. The specific analysis process is: compare the reference values of the current fluctuation amplitude and the average output particle size with the average load current, the current fluctuation amplitude and the average output particle size respectively, compare the metal wire cutting rate with the corresponding reference value, when the average load current is within the ideal range of the average load current, compare the average load current with the corresponding reference value, when the average load current exceeds the ideal range of the average load current, perform deviation processing on the average load current and the corresponding upper limit or lower limit, and couple each processing result with the corresponding distribution factor to obtain the scrap cable pulverization effect score.

[0090] It should be noted that the average load current reflects the overall workload of the pulverizer. If the current is high and fluctuates greatly, it may indicate that the material is too hard or the particle size is uneven, resulting in unstable pulverization resistance, which in turn makes the average particle size of the output material larger (not fully pulverized), and the wire shearing rate is reduced (the wire is not completely cut due to incomplete pulverization). On the contrary, if the current is stable and in a reasonable range, it usually means that the pulverization process is uniform and efficient, the average particle size of the output material is small and concentrated, and the wire shearing rate is high (sufficient cutting).

[0091] It should be noted that when the average load current is within the ideal range of the average load current, the higher the average load current, the more it indicates that the crusher is operating under a stable and reasonable load condition. At this time, the higher the average load current, it means that the shear force required for the cutter to cut the material is moderately strong, indicating that the density of the material entering the crusher is high, the cutting is sufficient, and the crushing efficiency in unit work is relatively high, that is, the better the crushing effect of the crusher. When the average load current is less than the ideal lower limit value of the average load current, it indicates that the motor load is small and the resistance during the crushing process is low. This often means that there is too little material, insufficient density, or the feeding speed is too fast, resulting in an increased probability of idling, insufficient or discontinuous shearing behavior, that is, the worse the crushing effect of the crusher. When the average load current is greater than the ideal upper limit value of the average load current, it indicates that the motor load is too heavy, which may be caused by too rapid feeding, too small knife clearance, or too high material density, resulting in the motor running close to overload, and may be accompanied by risks such as material blockage, tool jamming, and abnormal tool wear, that is, the worse the crushing effect of the crusher.

[0092] In a specific embodiment, the scoring method for the crushing effect of waste cables is as follows: , wherein, is the scoring for the crushing effect of waste cables, is the average load current, is the current fluctuation amplitude, is the average value of the discharge particle size, is the shearing rate of metal wires, is the reference average load current, is the ideal lower limit value of the average load current, is the ideal upper limit value of the average load current, is the reference average load current fluctuation value, is the reference current fluctuation amplitude, is the reference average value of the discharge particle size, is the reference shearing rate of metal wires, is the average load current distribution factor, is the current fluctuation amplitude distribution factor, is the average value of the discharge particle size distribution factor, is the shearing rate of metal wires distribution factor.

[0093] In this embodiment, the adaptive adjustment of the working parameters of the cable crusher is carried out in combination with the particle size distribution recognition result, and the specific analysis process is as follows: Analyze the corrected scoring of the crushing effect of waste cables based on the second parameter characterizing the particle size distribution of shredded waste cables and the scoring of the crushing effect of waste cables.

[0094] Extract the preset corrected threshold for the crushing effect of waste cables in the database.

[0095] Subtract the waste cable crushing effect correction threshold from the waste cable crushing effect correction score to obtain the waste cable crushing effect correction deviation score.

[0096] Extract the set of crusher working parameter adjustments corresponding to each waste cable crushing effect correction deviation score range stored in the database, and map and extract the set of crusher working parameter adjustments corresponding to the range in which the waste cable crushing effect correction deviation score is located, denoted as the cable crusher working parameter adjustment set.

[0097] The cable crusher working parameter adjustment set includes the adjustment value of the crusher main shaft speed and the adjustment value of the interval duration between the moving and fixed knives of the crusher.

[0098] It should be noted that if the waste cable crushing effect correction deviation score is less than zero, it indicates that the current crushing effect is weak, the discharge particle size is too large or the shearing is insufficient. To enhance the crushing strength, the main shaft speed of the crusher should be appropriately increased. Therefore, the corresponding adjustment value of the main shaft speed should be a positive value. At the same time, the duration of the shearing behavior should be increased to improve the shearing force, so the adjustment value of the interval duration between the moving and fixed knives should be a negative value. If the waste cable crushing effect correction deviation score is greater than zero, it indicates that the current crushing effect is too strong, and there may be situations such as over-crushing, excessive energy consumption or increased dust. To prevent equipment overload and over-crushing, the main shaft speed should be reduced. Therefore, the corresponding adjustment value of the main shaft speed should be a negative value. At the same time, the duration of the shearing behavior should be reduced to lower the shearing strength, so the adjustment value of the interval duration between the moving and fixed knives should be a positive value.

[0099] It should also be noted that the larger the numerical result of the waste cable crushing effect correction deviation score, the larger the numerical results of the corresponding extracted adjustment value of the crusher main shaft speed and the adjustment value of the interval duration between the moving and fixed knives of the crusher.

[0100] It should be added that the interval duration between the moving and fixed knives of the crusher refers to the duration during which the moving knife and the fixed knife maintain a preset minimum shearing distance during the operation of the crusher. Among them, the moving knife is a cutting component that rotates with the main shaft, and the fixed knife is a relatively fixed cutting edge. A shearing area is formed between the two. When the moving knife rotates to a position opposite to the fixed knife and reaches the set knife distance, it enters the effective shearing state. The interval duration between the moving and fixed knives represents the length of time for maintaining the effective shearing state, that is, the period during which the shearing force is effectively applied during each crushing and cutting process.

[0101] Perform adaptive adjustment of the cable crusher working parameters based on the initial cable crusher working parameter setting set and the cable crusher working parameter adjustment set.

[0102] In this embodiment, the analysis process of the waste cable crushing effect correction score is as follows: Extract the comminution effect correction coefficient corresponding to the second parameter interval of the particle size distribution of each shredded waste cable stored in the database, and map and extract the comminution effect correction coefficient corresponding to the interval where the second parameter of the particle size distribution of the shredded waste cable is located, which is denoted as the comminution effect correction coefficient of the waste cable.

[0103] It should be noted that the larger the second parameter characterizing the particle size distribution of the shredded waste cable, the more dispersed and less concentrated the particle size distribution of the shredded material. At this time, in order to further improve the particle size consistency and enhance the comminution uniformity during the comminution stage, the corresponding extracted comminution effect correction coefficient of the waste cable should also be larger.

[0104] Analyze the comminution effect correction score of the waste cable based on the comminution effect correction coefficient of the waste cable and the comminution effect score of the waste cable.

[0105] The comminution effect correction score of the waste cable is a quantitative index of the influence degree of the comminution effect correction coefficient of the waste cable and the comminution effect score of the waste cable on the actual comminution effect of the waste cable. The specific analysis process is to perform a correction process on the comminution effect score of the waste cable based on the comminution effect correction coefficient of the waste cable, so as to obtain the comminution effect correction score of the waste cable, that is, taking the product of the comminution effect correction coefficient of the waste cable and the comminution effect score of the waste cable as the numerical result of the comminution effect correction score of the waste cable.

[0106] Refer to Figure 8 As shown, it is the gravity separator interface of the composite wire recycling control system involved in the embodiment of the present application. From this, the copper-plastic ratio of the waste cable after passing through the gravity separator and the record of the air pressure adjustment of the gravity separator can be monitored.

[0107] S3. Convey the shredded waste cable to the gravity separator to separate the copper rice and plastic in the waste cable powder, obtain the copper-plastic ratio of the waste cable copper rice powder, and thereby feedback and adjust the air pressure of the gravity separator.

[0108] In this embodiment, the specific analysis steps for feedback and adjustment of the air pressure of the gravity separator are as follows: Extract the ideal copper-plastic ratio of the waste cable copper rice powder stored in the database.

[0109] If the copper-plastic ratio of the waste cable copper rice powder is less than the ideal copper-plastic ratio, then subtract the copper-plastic ratio from the ideal copper-plastic ratio to obtain the copper-plastic ratio deviation value.

[0110] If the copper-plastic ratio of the waste cable copper rice powder is less than the ideal copper-plastic ratio, it means that the current air pressure of the gravity separator is not sufficient to effectively separate the copper rice and plastic, resulting in insufficient blowing away of plastic particles, more plastic residues in the copper rice powder, and a lower copper-plastic ratio.

[0111] Extract the air pressure augmentation values corresponding to each copper-plastic ratio deviation value range stored in the database, and map and extract the air pressure augmentation value corresponding to the range where the copper-plastic ratio deviation value is located, which is denoted as the air pressure augmentation value of the gravity separator.

[0112] It should be noted that the larger the copper-plastic ratio deviation value, the more plastic that has not been effectively blown away, that is, the current air pressure is too small, resulting in plastic residue, and the larger the air pressure augmentation value of the gravity separator extracted correspondingly.

[0113] Feedback-adjust the air pressure of the gravity separator according to the air pressure augmentation value of the gravity separator. The specific process is as follows: Extract the current air pressure of the gravity separator from the system program log, and use the sum of the current air pressure of the gravity separator and the air pressure augmentation value of the gravity separator as the air pressure for the gravity separator to execute in the next cycle.

[0114] If the copper-plastic ratio of the waste cable copper powder is greater than or equal to the ideal copper-plastic ratio, no feedback adjustment of the air pressure of the gravity separator is performed.

[0115] If the copper-plastic ratio of the waste cable copper powder is greater than or equal to the ideal copper-plastic ratio, it indicates that the current air pressure setting of the gravity separator is reasonable, the copper and plastic in the copper powder have been effectively separated, and the copper-plastic ratio in the copper powder reaches the expected standard. There is no need to perform additional adjustment of the air pressure, and maintaining the current working condition can ensure the separation effect.

[0116] Refer to Figure 2 As shown, the second aspect of the present invention provides a control system for a copper-plastic separation production line of waste cables, including: A feeding device adjustment module, which is used for the shredder to receive waste cables for cable shredding, perform particle size distribution identification, and perform adaptive adjustment of the feeding device of the shredder based on the particle size distribution identification result.

[0117] A crusher working parameter adjustment module, which is used to convey the shredded waste cables to the cable crusher, set the initial working parameters of the cable crusher according to the particle size distribution identification result, analyze the crushing effect score of the waste cables, and perform adaptive adjustment of the working parameters of the cable crusher in combination with the particle size distribution identification result.

[0118] A gravity separator feedback adjustment module, which is used to convey the shredded waste cables to the gravity separator, separate the copper and plastic in the waste cable powder, obtain the copper-plastic ratio of the waste cable copper powder, and thereby feedback-adjust the air pressure of the gravity separator.

[0119] Refer to Figure 3As shown in the figure, the third aspect of the present invention provides a control device for a copper-plastic separation production line of waste cables, including: a feeding conveyor belt 1, an infrared detection sensor for the feeding conveyor belt (not shown in the figure), a shredder 2, an infrared detection sensor for the shredder (not shown in the figure), a shredder feeding device 3, a discharging conveyor belt 4, a cross magnetic separator 5, a cable crusher 6, a pneumatic conveying device 7, a cyclone separator 8, a gravity separator 9, a dust removal device 10, an industrial camera (not shown in the figure), and a controller (not shown in the figure).

[0120] Referring to Figure 5 As shown in the figure, it is the home page of the composite wire recycling control system involved in the embodiment of the present application. The system can monitor the recycling process of various metal-nonmetal composite wire materials in real time.

[0121] It should be added that the metal-nonmetal composite wire material is a material with a metal wire core (such as copper, aluminum) and an external plastic, rubber, polymer coating layer, including but not limited to: power cables, communication cables, electrical wiring harnesses, weak current wires, copper-plastic tapes, etc.

[0122] The feeding conveyor belt 1 is used to receive the incoming material of the front-end waste cable and convey it to the crushing chamber of the shredder 2.

[0125] The infrared detection sensor for the shredder is located on the wall of the crushing chamber of the shredder 2 and is used to detect whether the material state is at a high material level.

[0126] After the infrared detection sensor for the shredder monitors that the material is at a high material level, a high material level signal is generated, and the feeding conveyor belt stops feeding the material into the shredder In this embodiment, when the load current of the shredder exceeds 95% of the rated current and lasts for 3S, or when the infrared detection sensor for the shredder issues a high material level signal, the feeding conveyor belt stops feeding the material into the shredder. At the same time, in order to ensure efficient operation, through the infrared detection sensor, on the premise that the conveyor belt stops feeding the material into the conveyor, the material is sent to the end position of the conveyor belt and is in a state of waiting for material dropping.

[0127] It should also be added that the infrared sensor detects the incoming material at the current position through the principle of diffuse reflection. During the conveyor belt transmission, when it passes through the diffuse reflection range of the infrared sensor, if there is no accumulated material on the conveyor belt (no material), the infrared sensor will have no signal feedback, and the conveyor belt will continue to transmit. During the conveyor belt transmission, when it passes through the diffuse reflection range of the infrared sensor, if there is accumulated material on the conveyor belt (with material), the infrared sensor will output signal feedback, and the conveyor belt will stop at the infrared sensor detection position in time. Furthermore, the infrared sensor is installed at the end of the conveyor belt (the upper part of the crusher feed port) to ensure that the material is in the best position in the waiting area.

[0128] When the crusher overload / full load signal is released, the conveyor belt responds quickly and starts driving, and the material can quickly enter the crushing chamber of the crusher.
