Abstract
Description
Technical Field
[0001] This utility model relates to the field of particle processing technology, and in particular to a precision particle foreign object sorting and automatic feeding and weighing device. Background Technology
[0002] Particle sorting is a crucial operation that plays an irreplaceable role in numerous industries. In the food and pharmaceutical industries, it precisely removes impurities and non-compliant particles, ensuring product safety and quality. In mineral processing, it efficiently separates valuable minerals from gangue and rationally grades them, significantly improving beneficiation efficiency. In the field of electronic materials, the fine sorting of semiconductor particles lays a solid foundation for the performance of electronic components. Furthermore, particle sorting facilitates the full recycling of resources, reduces production costs, and optimizes catalyst use. In terms of environmental protection, it strengthens wastewater treatment and promotes the rational classification of solid waste, leveraging its comprehensive advantages to empower the steady development of various industries and the protection of the ecological environment.
[0003] Existing equipment typically consists of a feeding hopper, conveyor belt, motor, support frame, and vibrating screen. The support frame provides support for the equipment. Particles are added to the equipment through the feeding hopper, and then the motor drives the conveyor belt to transport the particles to the vibrating screen. The motor drives the vibrating screen to screen the particles according to their volume, facilitating subsequent processing steps.
[0004] However, vibrating screens can only screen particles by volume and cannot remove impurities of uniform particle size, such as metal shavings and broken particles. Furthermore, the vibrating screen can cause particles to be bumped and broken during the sorting process, which increases the defect rate, raises costs, and causes unnecessary losses. Therefore, a precision particle foreign object sorting and automatic feeding and weighing device is proposed to solve the above problems. Utility Model Content

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0038] Reference Figures 1-4This utility model provides an embodiment of a precision particle foreign matter sorting device, including a support leg 1, which provides support for the device and enables stable operation. A debris removal mechanism is installed on the outside of the support leg 1 to remove debris from the resin particles, facilitating subsequent processing steps. A conveying assembly is installed on the outside of the debris removal mechanism to move the resin particles, thereby facilitating processing by various mechanisms. A feed hopper 2 is fixedly connected to the outside of the support leg 1 for adding resin particles. The debris removal mechanism includes a chip removal component, a collection component, and an air separation component. The chip removal component includes a guard plate 7, which is fixedly connected to the support leg 1. On the outside, a protective plate 7 prevents resin particles from falling to the outside of the equipment, thus reducing material waste. A groove 8 is provided inside the protective plate 7, allowing impurities in the resin particles to enter the interior of the protective plate 7 for collection. An iron core 9 is fixedly connected inside the protective plate 7, and a conductive winding 10 is provided on the outside of the iron core 9. A power supply 11 is fixedly connected to the end of the conductive winding 10, providing power to energize the conductive winding 10. This energizes the conductive winding 10, which interacts with the iron core 9 to generate a magnetic field. This magnetic field attracts metallic impurities in the resin particles through the groove 8 into the interior of the protective plate 7, achieving the effect of removing metallic impurities. The collection assembly includes a recycling box 12, which is slidably connected... Inside the protective plate 7, a slider 13 is fixedly connected to the outside of the recycling bin 12. A slide rail 14 is provided inside the protective plate 7. Through the cooperation of the slide rail 14 and the slider 13, the recycling bin 12 can slide in the protective plate 7. The cleaned metal impurities fall into the recycling bin 12 through the groove 8, thereby achieving the recycling effect of metal impurities. The conveying component includes a roller 5, which is rotatably connected to the outside of the support leg 1. A conveyor belt 6 is sleeved on the outside of the roller 5. A support plate 3 is fixedly connected to the outside of the support leg 1. A motor 4 is fixedly connected to the top of the support plate 3. The output end of the motor 4 is fixedly connected to the end of the roller 5. The support plate 3 provides support for the motor 4, allowing it to run smoothly. Powered by motor 4, the roller 5 rotates, which in turn moves the conveyor belt 6, thus achieving the transmission of resin particles. The air separation component includes an electric fan 19, which is fixedly connected to the outside of the support leg 1. A hopper 15 is fixedly connected to the outside of the support leg 1. A discharge trough 18 is opened inside the hopper 15. A discharge pipe 17 is fixedly connected to the bottom of the hopper 15. A waste discharge pipe 16 is fixedly connected to the outside of the hopper 15. The conveyor belt 6 transports the resin particles into the hopper 15. At this time, the electric fan 19 is started to discharge the defective and dust particles from the resin particles. The discharged defective and dust particles are discharged from the equipment through the waste discharge pipe 16, while the good resin particles are discharged through the discharge pipe 17.
[0039] Reference Figure 1 , Figure 5 , Figure 6 and Figure 7 An automatic feeding and weighing device includes a baffle 20, which provides a blocking effect to prevent resin particles from falling out of the device during transmission, thereby reducing material waste. A transport component is installed on the outside of the baffle 20 to move the resin particles, facilitating subsequent processing steps. A feeding mechanism is placed on the outside of the baffle 20 to move the resin particles, thereby achieving the resin particle transmission effect. A weighing component is placed on the outside of the feeding mechanism to weigh the resin particles, limiting the number of resin particles and facilitating subsequent resin particle processing steps. The transport component includes a second roller 23, which is rotatably connected to the baffle. On the outer side of plate 20, a conveying grid 24 is fitted around the outer side of roller 23. A support plate 21 is fixedly connected to the outer side of baffle 20, and a motor 22 is fixedly connected to the top of support plate 21. The output end of motor 22 is fixedly connected to the outer side of roller 23. Support plate 21 provides support for motor 22, allowing it to run smoothly. Motor 22 provides power to drive roller 23 to rotate, which in turn moves conveying grid 24, thereby conveying resin particles and making subsequent processing steps more convenient. The feeding mechanism includes a power component and a conveying component. The power component includes a support block 31, which is placed on the ground. A housing 25 is fixedly connected to the top of support block 31. The outer casing 25 provides support, making it more stable during operation and preventing displacement. A drive motor 26 is fixedly connected to the bottom of the outer casing 25, and a rotating shaft 27 is fixedly connected to the output end of the drive motor 26. The drive motor 26 provides power to drive the rotating shaft 27 to rotate. The conveying assembly includes a rotating plate 28, which is fixedly connected to the outside of the rotating shaft 27. Both the rotating plate 28 and the outer casing 25 have discharge ports 29 in the middle. A guard plate 30 is fixedly connected to the edge of the discharge port 29 of the rotating plate 28. The rotating shaft 27 drives the rotating plate 28 to rotate, causing the resin particles to fall into the discharge port 29 of the rotating plate 28. Then, the discharge port 29 and the guard plate 30 cooperate to convey the resin particles to the outer casing 25. The resin particles are conveyed to the next processing step through the discharge port 29 of the outer shell 25. The weighing component includes a fixed block 32, which is placed on the ground. A pressure sensor 33 is installed on the top of the fixed block 32, and a tray 34 is placed on top of the pressure sensor 33. The fixed block 32 provides support so that the weighing component can operate smoothly. When the resin particles reach the tray 34, the pressure sensor 33 under the tray 34 converts the detection signal into an electrical signal and transmits it to the external controller. When the weight of the resin particles reaches the set value, the external controller controls the drive motor 26 to stop running, thereby stopping the conveying of the resin particles. At this time, the resin particles in the tray 34 can be packaged or otherwise processed.
[0040] Working principle: During operation, resin granules arrive at the conveyor belt 6 from the feed hopper 2. Motor 4 drives roller 5 to rotate, which in turn drives the conveyor belt 6. At this time, power supply 11 energizes the conductive winding, which, in conjunction with the iron core 9, generates a magnetic field to clean the metal impurities in the granules. The cleaned resin granules are then conveyed by the conveyor belt 6 to the discharge hopper 15. The electric fan starts, removing defective and dusty resin granules. The dust and defective granules are discharged through the waste discharge pipe 16, while good granules are discharged through the discharge trough 18 and reach the conveyor grid. On 24, motor 22 starts and drives roller 23 to rotate. Roller 23 drives conveyor grid 24 to run, and then conveys the resin particles to the outer shell 25. At this time, drive motor 26 starts and drives rotating shaft 27 and turntable 28 to rotate. The resin particles are conveyed to tray 34 through feeding port 29 and guard plate 30. The weight index of the particles is transmitted to external controller through pressure sensor 33, thereby realizing the weighing effect. After weighing is completed, tray 34 can be picked up, and the resin particles in tray 34 can be packaged.
[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
