Description

Technical Field

[0001] This invention relates to the field of cable plastic processing technology, and in particular to a color sorting device for cable plastic particles. Background Technology

[0002] Cable plastic granules are the core raw material for the preparation of cable sheaths and insulation layers. The uniformity of their appearance and color directly determines the insulation performance, mechanical strength and appearance quality of the finished cable. Therefore, in the cable production and processing stage, cable plastic granules need to be subjected to high-precision color sorting to remove discolored and impurity particles and ensure the purity of raw materials. Currently, most color sorting devices for cable plastic granules in the industry adopt a core structure of visual sensing + pneumatic spraying. The visual sensing component identifies the color difference of the granules, and then the air pump supplies air and the spraying component sprays air to remove unqualified granules. The air pump output of the existing color sorting device is directly delivered to the spraying component through the pipeline. The dust, water vapor, oil and other impurities contained in the air source cannot be effectively filtered, which can easily cause nozzle blockage and air supply valve jamming. This leads to uneven spraying force and airflow dispersion. At best, it will result in incomplete removal of discolored granules and mis-spraying of qualified products, which will greatly reduce the color sorting pass rate. At worst, it will damage the core components of the spraying component. At the same time, oil and water vapor can invade the solenoid valve of the spraying component, causing valve core adhesion, aging and failure of the sealing ring, and problems such as solenoid valve jamming, air leakage or failure to open and close normally.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention, through the combination of the filter rotor and carbon balls in the adsorption component, can deeply adsorb and filter impurities such as dust, water vapor, and oil in the air source output by the air pump, ensuring the purity of the air source of the jet component and avoiding nozzle blockage and air replenishment valve jamming; at the same time, the heating component of the circulation component can heat and regenerate the adsorbed saturated carbon balls, and with the feed cylinder and discharge pipe driven by the spiral impeller, the carbon balls can be automatically circulated and reused between the filter rotor and the storage tank, eliminating the need for frequent manual replacement of filter media, which not only reduces resource waste, but also avoids production interruptions caused by downtime maintenance, and significantly reduces equipment use and maintenance costs.

[0015] 2. This invention employs a design with multiple sets of jet components distributed at different angles, which can fully cover the trajectory of falling plastic particles, adapt to actual working conditions such as particle dispersion and deviation, avoid missed selection, and the guide plate at the nozzle can concentrate the jet airflow to prevent qualified products from being sprayed due to airflow diffusion. The air replenishment valve can adjust the air pressure in real time to ensure stable jetting force, greatly improve the color sorting accuracy, and ensure the qualified rate of cable plastic particles.

[0016] 3. This invention can drive the rotating plates inside the filter wheel to rotate via a motor, allowing the carbon balls between multiple rotating plates to be used for filtration in turn. This not only ensures the filtration effect of the air jet, but also allows the carbon balls to be regenerated in time after use, improving production efficiency. At the same time, the annular filter screen of the filter assembly can achieve self-cleaning under the action of the scraper. Combined with the pressing and guiding of the spring pressure plate and roller, it ensures the continuity of filtration and avoids filter screen blockage affecting the air supply.

[0017] 4. The present invention adds an illumination component near the visual sensing component, which can provide a uniform and stable lighting environment, avoiding color recognition errors caused by surface reflection and uneven lighting of cable plastic particles. Furthermore, the reasonable layout of the visual sensing component, the hopper, and the air jet assembly, combined with precise airflow jet control, can achieve efficient coordination of "identification and jetting", further improving the accuracy of identification and rejection of discolored and impurity particles, and ensuring the color uniformity of plastic particles after color sorting.

[0018] 5. This invention uses an electrostatic adsorption plate to further adsorb fine impurities carried in the carbon ball circulation process, improving the regeneration accuracy of the carbon ball. At the same time, the continuous movement of the pressure block in the pressure assembly ensures smooth flow of the carbon ball in the storage box and feed cylinder. The multi-structure synergy improves the adaptability and operational reliability of the device, meeting the diverse and large-scale color sorting needs of cable plastic granules.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figure 1-9 This invention provides a color sorting device for cable plastic granules, including a support frame 1. A hopper 5 is fixedly installed at the top of the support frame 1. A visual sensing component 3 is provided in the middle section of the support frame 1 near the hopper 5. A color sorting mechanism 6 is provided at one end of the support frame 1. The color sorting mechanism 6 includes an air pump 61 fixedly installed at the top of the support frame 1. A plurality of air jet components 66 for color sorting are provided at the top of the support frame 1. The output end of the air pump 61 is connected to the air jet components 66 through an air outlet pipe 62. An adsorption component 63 is provided on the air outlet pipe 62. The adsorption component 63 includes a filter wheel 633 rotatably installed at the top of the support frame 1. The interior of the filter wheel 633 is filled with carbon balls 634 for filtering air. A circulation component 67 is provided at the bottom of the filter wheel 633. The circulation component 67 includes a storage box 672 connected to the bottom of the filter wheel 633. A heating component 671 for heating the carbon balls 634 is provided on one side of the storage box 672.

[0023] In the process of color sorting cable plastic particles, the air pump 61 generates compressed air, which is delivered to the jet assembly 66 through the air outlet pipe 62. The jet assembly 66 can identify colored plastic particles and spray them out, thereby achieving color sorting of plastic particles. The filter wheel 633 of the adsorption assembly 63 is filled with carbon balls 634 to filter the gas sprayed by the jet assembly 66, reducing gas impurities and moisture, and improving the accuracy of jetting. At the same time, the storage box 672 and the heating component 671 of the circulation assembly 67 are used for the circulation and heating regeneration of carbon balls 634, so that carbon balls 634 can be recycled.

[0024] In some embodiments, a plurality of rotating plates 635 are rotatably mounted inside the filter wheel 633, and carbon balls 634 are filled between the plurality of rotating plates 635. A motor 631 is fixedly mounted on the top of the support frame 1, and a first belt 632 is driven between the output shaft of the motor 631 and the rotating plates 635.

[0025] The motor 631 drives the rotating plate 635 inside the filter wheel 633 to rotate via the first belt 632, causing the carbon balls 634 filled between the rotating plates 635 to roll inside the filter wheel 633, increasing the contact area between the carbon balls 634 and the gas, and improving the filtration effect. At the same time, the carbon balls 634 between multiple rotating plates 635 are used for filtration in turn, and the used carbon balls 634 can be regenerated in time, improving production efficiency.

[0026] In some embodiments, a feed cylinder 676 is connected to the top of the storage tank 672, the discharge end of the feed cylinder 676 is connected to the top of the filter wheel 633, a spiral impeller 675 is rotatably mounted inside the feed cylinder 676, a first bevel gear 677 is fixedly mounted on the top of the spiral impeller 675, a second bevel gear 678 is rotatably mounted on the top of the support frame 1, and the first bevel gear 677 meshes with the second bevel gear 678. The output shaft of the motor 631 is connected to one end of the second bevel gear 678 via a second belt 679.

[0027] In this system, motor 631 drives second bevel gear 678 to rotate via second belt 679. Second bevel gear 678 drives first bevel gear 677 to rotate. First bevel gear 677 drives spiral impeller 675 to rotate. Spiral impeller 675 transports carbon balls 634 from storage bin 672 to the top of filter rotor 633 via feed cylinder 676, realizing automatic transport of carbon balls 634 from storage bin 672 to filter rotor 633. This ensures a sufficient supply of carbon balls 634 in filter rotor 633, allowing the filtration process to proceed continuously and stably, improving the automation level and production efficiency of the device. At the same time, motor 631 not only drives filter rotor 633 to transport carbon balls, but also enables the carbon balls 634 used in color sorting to be recycled through multiple bevel gear sets and multiple belt drives, thereby improving color sorting efficiency.

[0028] In some embodiments, the top of the storage tank 672 is connected to the bottom of the filter wheel 633 through the discharge pipe 673. Both ends of the discharge pipe 673 are provided with electrostatic adsorption plates 674 for adsorbing impurities, and the arc-shaped electrostatic adsorption plates 674 are attached to the inside of the pipe wall. The electrostatic adsorption plates 674 are electrically connected to the electrostatic generator through the built-in power supply.

[0029] The discharge pipe 673 is equipped with electrostatic adsorption plates 674 at both ends. The electrostatic generator charges the electrostatic adsorption plates 674 through the built-in power supply. When the carbon balls 634 move in the discharge pipe 673, impurities are adsorbed by the electrostatic adsorption plates 674, effectively removing the impurities adsorbed on the surface of the carbon balls 634, further improving the filtration effect of the carbon balls 634, and ensuring the purity of the carbon balls 634 entering the filter rotor 633.

[0030] In some embodiments, a pressurizing assembly 68 is provided inside the discharge pipe 673. The pressurizing assembly 68 includes a fixed rod 682 slidably installed inside the discharge pipe 673. A pressurizing block 681 for pushing the carbon ball 634 to move is fixedly installed at the bottom end of the fixed rod 682. A sliding plate 684 is fixedly installed at the top end of the fixed rod 682. A disc 683 is rotatably installed at the top end of the support frame 1. A round rod 685 is fixedly installed on the outer surface of the disc 683. The round rod 685 is slidably installed inside the sliding plate 684. A third belt 686 is driven between the rotating shaft of the disc 683 and one end of the first bevel gear 677.

[0031] The first bevel gear 677 drives the disc 683 to rotate via the third belt 686. The round rod 685 on the disc 683 slides inside the slide plate 684, causing the slide plate 684 to drive the fixed rod 682 and the pressure block 681 to move up and down reciprocally. This pressurizes and pushes the carbon balls 634 in the discharge pipe 673, preventing the carbon balls 634 from clogging the discharge pipe 673, ensuring smooth circulation of the carbon balls 634, improving the working efficiency of the entire adsorption assembly 63 and circulation assembly 67, and assisting the spiral impeller 675 in circulating the carbon balls 634 to ensure the filtration effect.

[0032] In some embodiments, a mounting plate 65 is fixedly installed on the top of the support frame 1, and multiple jetting components 66 are evenly distributed on the surface of the mounting plate 65 near the hopper 5, and multiple sets of jetting components 66 at different angles are provided on the mounting plate 65.

[0033] The mounting plate 65 is fixed to the top of the support frame 1. Multiple jetting components 66 are evenly distributed on the surface of the mounting plate 65 near the hopper 5. Multiple sets of jetting components 66 at different angles can spray and separate particles of different colors from different angles according to the results identified by the vision sensing component 3, thereby improving the accuracy and efficiency of color sorting and reducing mis-selection and missed selection.

[0034] In some embodiments, the jet assembly 66 includes a plurality of nozzles 661 connected to one end of the air outlet pipe 62. A gas replenishment valve 662 for replenishing and regulating gas pressure is provided on one side of the nozzle 661, and a gas guide plate 663 for concentrating gas is provided at the nozzle of the nozzle 661.

[0035] The gas replenishment valve 662 can replenish gas as needed and adjust the gas pressure at the nozzle 661 to adapt to different particle and color sorting requirements, ensuring that unqualified particles can be accurately blown away from the normal track.

[0036] In some embodiments, a filter assembly 64 is provided on the air outlet pipe 62. The filter assembly 64 includes a filter plate 641 connected to and installed on the air outlet pipe 62. An annular filter screen 643 for filtering impurities is slidably installed inside the filter plate 641, and a plurality of scrapers 642 for cleaning the annular filter screen 643 are fixedly installed inside the filter plate 641.

[0037] When the gas passes through the annular filter 643 inside the filter plate 641, the annular filter 643 effectively filters impurities in the gas, preventing impurities from entering the jet assembly 66 and affecting the jetting effect; the scraper 642 can clean the surface of the annular filter 643, ensuring the filtering performance of the filter, reducing manual maintenance, and improving the stability and reliability of the device.

[0038] In some embodiments, a fixing plate 644 is symmetrically installed inside the filter plate 641, a spring 646 is fixedly installed on the surface of the fixing plate 644, a pressure plate 645 is fixedly installed on the free end of the spring 646, and a roller 647 is rotatably installed between the two pressure plates 645, and the annular filter screen 643 slides through the two rollers 647, and a driving component is externally connected to one end of the roller 647.

[0039] The filter plate 641 is symmetrically fitted with fixing plates 644. A spring 646 causes a pressure plate 645 to press a roller 647 against an annular filter screen 643. The annular filter screen 643 slides between the two rollers 647. The rollers 647 reduce the friction of the annular filter screen 643 during sliding and ensure stable sliding of the annular filter screen 643. This reduces the resistance to sliding of the annular filter screen 643 and ensures the stable position of the annular filter screen 643 within the filter plate 641. The rollers 647 are driven to rotate by a driving component. At this time, the two rollers 647 can transmit power to the annular filter screen 643 in the limiting position, so that the annular filter screen 643 can slide inside the filter plate 641. This allows the scraper 642 to accurately clean the filter screen and improve the working efficiency and reliability of the filter assembly 64.

[0040] In some embodiments, a waste bin 2 and a finished product discharge component 7 are provided on the support frame 1 near the top of the hopper 5, and an illumination component 4 is provided on the support frame 1 near the vision sensing component 3.

[0041] Among them, the waste bin 2 is used to collect unqualified particles blown away during the color sorting process, the finished product discharge component 7 discharges qualified cable plastic particles from the device, and the lighting component 4 provides sufficient light for the visual sensing component 3 to ensure the accuracy of color recognition.

[0042] Working principle: This cable plastic granule color sorting device is based on the support frame 1. The hopper 5 is used to feed cable plastic granules. The visual sensing component 3 identifies the color of the falling granules. The air pump 61 generates compressed air, which is delivered to the jet assembly 66 through the air outlet pipe 62. The jet assembly 66 can identify colored plastic granules and spray them out, thereby achieving color sorting of plastic granules. The filter wheel 633 of the adsorption component 63 is filled with carbon balls 634 to filter the gas sprayed by the jet assembly 66, reducing gas impurities and moisture, and improving the jet accuracy. At the same time, the storage tank 672 and the heating component 671 of the circulation component 67 are used for the circulation and heating regeneration of carbon balls 634, so that carbon balls 634 can be recycled.

[0043] The above are merely specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on the present invention to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of the present invention.
