Description

Particle size sorting machine with online detection Technical Field

[0001] This utility model relates to the field of sorting machine technology, and in particular to a particle size sorting machine with online detection. Background Technology

[0002] A particle size separator is an industrial device used to separate materials based on differences in particle size. It is widely used in mining, chemical, pharmaceutical, food processing and environmental protection fields. Its working principle is mainly based on technologies such as screening, air separation, centrifugal separation or optical recognition, which classifies mixed particles into a preset particle size range through physical or mechanical means.

[0003] In the field of environmental protection, recycled plastics generally need to be crushed and then sorted by a sorting machine to remove oversized or undersized particles, ensuring the uniformity and efficiency of subsequent sorting. However, recycled plastics usually contain some metal fragments, such as tires and some electrical appliance casings. These may be mixed with metals during processing, and there is no reliable way to detect and process metals in plastics online. Therefore, these metal fragments will follow the plastics in subsequent processing, affecting the quality of the plastics.

The flexible magnetic sheet is embedded in the outer surface of the conveyor belt.

[0008] The surface of the flexible magnetic sheet is flush with the surface of the transmission belt. The surfaces of the drive shaft and the transmission shaft are fitted with side guard plates near both ends via bearings. The inner side of the side guard plate is movably connected to the side of the transmission belt.

[0009] The width of the hopper matches the width of the transmission belt, and the discharge port at the bottom of the hopper is close to the top of the transmission belt.

The mounting plate is fixedly installed on the top of the side guard plate. The two sets of drive plates are movably connected to the mounting plate. The two ends of the two sets of drive plates pass through the mounting plate and the detection box and extend to the outside of the detection box. The feeding rod is fixedly connected to the bottom of the drive plate. The bottom end of the feeding rod is movably connected to the surface of the transmission belt. The fixed seat is fixedly connected to the side of the detection box. The transmission wheel is rotatably connected to the top of the fixed seat. The strip toothed groove is respectively opened on the opposite side of the two sets of drive plates and close to the transmission wheel. The strip toothed groove and the transmission wheel mesh with each other. The top frame is fixedly connected to the top of one set of drive plates near the end face. The drive head is movably connected inside the top frame. The handle is fixedly connected to the top of the drive head. The end of the handle away from the drive head is fixedly connected to the output shaft of the drive motor. The drive motor is fixedly installed on the side of the detection box.

[0011] The collection kit includes a fixed frame, a movable collection frame, and a scraper. The fixed frame is fixedly connected to the bottom of the side guard plate near the output end. The movable collection frame is movably connected inside the fixed frame, and one end of the movable collection frame extends to the outside of the detection box. The scraper is fixedly connected to the surface of the side guard plate near the tail end of the movable collection frame and located at the bottom of the transmission belt.

[0014] The beneficial effects of this utility model are:

[0015] By setting up a detection box and an online detection conveying component, the material enters the online detection conveying component through the hopper. After contacting the transmission belt, the metal in the material is detected by the flexible magnetic sheet and small metal particles are adsorbed, thus achieving the purpose of online detection of metal in the material. This solves the problem that recycled plastics generally contain some metal fragments, and there is no reliable way to detect and process these metals online, which affects the quality of the plastics.

[0016] By setting up a collection kit, the kit scrapes and sweeps away small metal particles that are adsorbed, causing them to fall into a movable collection box within the kit for collection. Cleaning is achieved simply by moving the movable collection box, thus achieving the purpose of collecting and cleaning up metal debris.

[0017] By setting up a reciprocating feeding component, the reciprocating feeding component will push the material on the surface of the transmission belt to spread it out fully, so that the flexible magnetic sheet can fully detect the metal in the material and adsorb it.

[0027] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0028] Referring to Figures 1-7, this embodiment includes a sorting machine body 1. The top of the sorting machine body 1 is provided with a detection box 2 that communicates with the sorting machine inlet. The inside of the detection box 2 is provided with an online detection conveying component 3. The output end of the online detection conveying component 3 is located directly above the inlet of the sorting machine body 1.

[0029] The top of the detection box 2 is provided with a hopper 4 above the online detection conveying assembly 3. The bottom end of the hopper 4 extends to the position of the online detection conveying assembly 3. The online detection conveying assembly 3 includes a conveying motor 6, a transmission shaft 7, a drive shaft 8, a transmission belt 9, and a flexible magnetic sheet 10. The transmission shaft 7 and the drive shaft 8 are rotatably connected inside the detection box 2 through fixed bearings. The drive shaft 8 extends to the outside of the detection box 2 and is fixedly connected to the output shaft of the transmission motor 6. The transmission motor 6 is fixedly installed on the side of the detection box 2. The two ends of the transmission belt 9 are respectively movably sleeved on the surfaces of the transmission shaft 7 and the drive shaft 8. The flexible magnetic sheet 10 is embedded in the outer surface of the transmission belt, and the surface of the flexible magnetic sheet 10 is flush with the surface of the transmission belt 9. The surfaces of the drive shaft 8 and the transmission shaft 7 are rotatably sleeved with side guard plates 11 through bearings near the two ends. The inner side of the side guard plate 11 is movably connected to the side of the transmission belt 9. The width of the hopper 4 matches the width of the transmission belt 9, and the bottom outlet of the hopper 4 is close to the top of the transmission belt 9.

[0030] In practice, the material is fed through the hopper 4, which guides the material to the top of the transmission belt 9. As shown in Figure 6, the material is thinly spread on the surface of the transmission belt 9 due to the narrow distance between the hopper 4 and the transmission belt 9. The flexible magnetic sheet 10 on the surface of the transmission belt 9 performs online real-time detection of metal debris in the material and adsorbs the metal debris after detection. It should be noted that the magnetic force of the flexible magnetic sheet 10 is controlled according to the actual weight of the metal debris. If the mass of the metal debris is generally between 1 gram and 50 grams, and considering safety redundancy, the actual magnetic force design needs to be slightly higher than the theoretical value, controlled between 0.15 and 0.4T. Those skilled in the art will make the relevant settings based on common sense, which will not be elaborated here. The material of the flexible magnetic sheet 10 is generally a flexible magnetic sheet 10 composite of iron-silicon-aluminum magnetic powder and polyurethane, which can be bent and belongs to the prior art, which will not be elaborated here either.

[0031] Referring to Figures 1-7, in this embodiment, the bottom of the detection box 2 is provided with a collection kit 5 for collecting metal. The collection kit 5 includes a fixed frame 23, a movable collection frame 24, and a scraper 25. The fixed frame 23 is fixedly connected to the bottom of the side guard plate 11 near the output end. The movable collection frame 24 is movably connected inside the fixed frame 23, and one end of the movable collection frame 24 extends to the outside of the detection box 2. The scraper 25 is fixedly connected to the surface of the side guard plate 11 near the tail end of the movable collection frame 24 and located at the bottom of the transmission belt 9. The top of the scraper 25 is tightly attached to the lower surface of the transmission belt 9. The surface of the side guard plate 11 is rotatably connected to a positioning shaft 26 at the bottom of the inner wall of the transmission belt 9. The surface of the positioning shaft 26 is movably connected to the bottom of the inner wall of the transmission belt 9, and the positioning shaft 26 is located directly above the scraper 25.

[0032] In practice, since the metal scraps are attracted by the flexible magnetic sheet 10, after reaching the output end of the conveyor belt 9, the plastic in the material will separate from the metal scraps, and the material will fall into the sorting machine. The metal scraps will be attracted and carried to the bottom of the conveyor belt 9. When the metal scraps reach the collection kit 5 below the conveyor belt 9, the metal scraps are blocked by the scraper 25. At this time, the metal scraps will stay inside the movable collection frame 24. When too many metal scraps stay, the metal scraps will fall into the movable collection frame 24 for collection due to their own gravity. Since one end of the movable collection frame 24 is located outside the detection box 2, when it is necessary to clean the metal scraps, it is only necessary to pull the movable collection frame 24 to separate the movable collection frame 24 from the fixed frame 23 and the detection box 2. In this way, the metal scraps in the movable collection frame 24 can be quickly cleaned.

[0033] Referring to Figures 1-7, in this embodiment, the top of the side guard plate 11 is provided with a reciprocating feeding assembly 12 for feeding material. The reciprocating feeding assembly 12 includes a mounting plate 13, two sets of driving plates 14, a feeding rod 15, a strip toothed groove 16, a fixed seat 17, a transmission wheel 18, a top frame 19, a driving head 20, a rotating handle 21, and a drive motor 22. The mounting plate 13 is fixedly installed on the top of the side guard plate 11. The two sets of driving plates 14 are movably connected to the mounting plate 13. The two ends of the two sets of driving plates 14 pass through the mounting plate 13 and the detection box 2 and extend to the outside of the detection box 2. The feeding rod 15 is fixedly connected to the bottom of the driving plate 14, and the bottom end of the feeding rod 15 is movable. The transmission belt 9 is connected to the surface of the transmission belt 9. The fixed seat 17 is fixedly connected to the side of the detection box 2. The transmission wheel 18 is rotatably connected to the top of the fixed seat 17. The strip-shaped toothed grooves 16 are respectively opened on the opposite sides of the two sets of driving plates 14 and close to the transmission wheel 18. The strip-shaped toothed grooves 16 and the transmission wheel 18 mesh with each other. The top frame 19 is fixedly connected to the top of the set of driving plates 14 near the end face. The driving head 20 is movably connected to the inside of the top frame 19. The rotating handle 21 is fixedly connected to the top of the driving head 20. The top of the rotating handle 21 away from the driving head 20 is fixedly connected to the output shaft of the drive motor 22. The drive motor 22 is fixedly installed on the side of the detection box 2.

[0034] In specific implementation, to further improve the efficiency of online detection, the drive motor 22 is started. The start of the drive motor 22 will drive the rotating handle 21 to rotate, and the rotation of the rotating handle 21 will drive the drive head 20 to rotate. When the drive head 20 rotates around the output shaft of the drive motor 22, it will drive the top frame 19 to move back and forth, converting the rotational motion into reciprocating linear motion. The reciprocating motion of the top frame 19 will drive a set of drive plates 14 to move back and forth. The reciprocating motion of the set of drive plates 14 on the mounting plate 13 will drive the transmission wheel 18 to rotate back and forth. The reciprocating motion of the transmission wheel 18 will drive another set of drive plates 14 to move back and forth. It should be noted that when one set of drive plates 14 moves, the other set of drive plates 14 moves in the opposite direction under the drive of the transmission wheel 18. The reciprocating motion of the two sets of drive plates 14 will drive the material-pulling rod 15 to move back and forth, which will paddle the material back and forth, making it spread out more fully and improving the detection efficiency of the flexible magnetic sheet 10 for metal scraps.

[0035] Referring to Figures 1-7, in this embodiment, the collection kit 5 further includes a cleaning assembly 27, which includes a connecting seat 28, a cleaning brush 29, a first pulley 30, a connecting belt 31, and a second pulley 32. The connecting seat 28 is fixedly connected to the bottom of the side guard plate 11, the cleaning brush 29 is rotatably connected to the connecting seat 28, the first pulley 30 is fixedly connected to the end face of the cleaning brush 29, the second pulley 32 is fixedly connected to the surface of the drive shaft 8, and the two ends of the connecting belt 31 are respectively movably sleeved on the surfaces of the first pulley 30 and the second pulley 32.

[0036] In practice, when the drive shaft 8 rotates, it will drive the second pulley 32 to rotate. The rotation of the second pulley 32 will drive the connecting belt 31 to rotate. The rotation of the connecting belt 31 will drive the first pulley 30 to rotate. The rotation of the first pulley 30 will drive the cleaning brush 29 to rotate on the connecting seat 28. The rotation of the cleaning brush 29 will clean the metal debris adsorbed on the lower surface of the transmission belt 9, so as to avoid continuous adsorption on the flexible magnetic sheet 10.

[0037] The method of using this utility model is as follows:

[0038] During operation, the online detection conveying assembly 3 is first started, and then the material is poured into the hopper 4. The hopper 4 conveys the material to the surface of the transmission belt 9 on the online detection conveying assembly 3. The start of the conveyor motor 6 drives the drive shaft 8 to rotate, which in turn drives the transmission belt 9 and the drive shaft 7 to rotate together. The rotation of the transmission belt 9 moves and conveys the material. Because the distance between the discharge port of the hopper 4 and the transmission belt 9 is short, the material spread on the surface of the transmission belt 9 is relatively thin. After the conveyor belt moves the material, the reciprocating feeding assembly 12 moves and spreads the material on the surface of the transmission belt 9. Then, the flexible magnetic sheet 10 on the surface of the transmission belt 9 performs online detection of metal fragments in the material. The system adsorbs metal debris from the material. After being adsorbed, the metal debris travels to the collection kit 5 via the conveyor belt 9. At this point, plastic particles in the material, which are not adsorbed, fall into the sorting machine for sorting. The metal debris, after being adsorbed, follows the conveyor belt 9 to the collection frame. Then, the cleaning component 27 cleans the adsorbed metal debris, causing it to fall into the movable collection frame 24 by gravity, thus completing the collection of metal debris. During cleaning, the movable collection frame 24 is moved outward to separate it from the fixed frame 23. The scraper 25 adsorbs the more stubborn metal debris, causing it to be blocked and remain in the movable collection frame 24. After accumulating a large amount, it will fall into the movable collection frame 24 by gravity.

[0039] It should be noted that the rotating connections in this technical solution all achieve the rotation effect through bearings.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
