Description

Technical Field

[0001] This utility model relates to the field of extruded polystyrene board edge recycling devices, and more particularly to an edge recycling and reuse device for extruded polystyrene boards. Background Technology

[0002] The XPS board edge recycling device is a resource-based treatment system designed for edge materials and waste generated during XPS board production. Its core function is to transform waste edge materials into reusable production raw materials through physical processing. It primarily removes impurities and refines particles from the edge materials through key processes such as crushing, screening, and purification. The processed recycled material is then mixed with virgin material in a specific ratio and directly fed into the main XPS board production line for recycling. This device effectively reduces solid waste emissions, lowers raw material procurement costs, and achieves a closed-loop utilization of "edge materials - recycled materials - recycled products." It is an important piece of equipment for the XPS board industry to practice green production and improve economic efficiency, and is widely adaptable to the actual needs of small and medium-sized production lines.

[0003] However, the current extruded board edge recycling equipment has the following defects: it lacks the function of magnetic separation of metal impurities, requiring manual picking of metal impurities. Some devices that use magnets for magnetic separation have the problem of inconvenient magnet replacement and cannot achieve automatic removal of metal objects from the magnet. The collection efficiency of metal impurities is low, which affects the continuity of the recycling process. In response to this technical problem, this application proposes a device for recycling and reusing edge materials of extruded polystyrene boards. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a device for recycling and reusing edge materials of extruded polystyrene boards. This device aims to perform magnetic separation on the edge materials to pick out internal metal impurities, reduce the pressure of subsequent manual sorting, facilitate the replacement of magnets by workers, and automatically remove metal objects from the magnets, thereby collecting the metal impurities.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A device for recycling and reusing scrap from extruded polystyrene boards includes a housing. Two guide plates are fixedly connected to the front and rear sides of the housing. Two crushing rollers are rotatably connected inside the housing, positioned between the upper and lower guide plates. A rotating plate is rotatably connected to the rear side of the housing via a hinge. A magnet is inserted into the rotating plate. A fixing component is provided inside the rotating plate to fix the magnet to the rotating plate. A positioning component is provided between the rotating plate and the housing to fix the rotating plate to the housing. A scraping component is provided inside the housing to sweep away metal objects adsorbed on the magnet.

[0006] Furthermore, the fixing assembly includes two insert rods inserted into the interior of the rotating plate. The insert rods pass through a magnet, and a groove is provided at the top end of the insert rod. A fixing tube is fixedly connected inside the groove, and a pull ring is rotatably connected inside the fixing tube.

[0007] Furthermore, the positioning assembly includes a fixing plate fixedly connected to the rear side of the housing and the rotating plate, and a positioning rod is inserted between the two fixing plates.

[0008] Furthermore, the scraping assembly includes a fixing groove fixedly connected to the left and right sides of the housing, and a scraper is slidably connected inside the housing and the fixing groove, with the rear side of the scraper abutting against the front side of the magnet.

[0009] Furthermore, through slots are provided on both the left and right sides of the box, and collection boxes are provided on both the left and right sides of the box. A reciprocating screw is rotatably connected between the two fixed slots, and the top of the scraper is sleeved on the outer wall of the reciprocating screw. Two rubber strips are fixedly connected between the two fixed slots.

[0010] Furthermore, the right ends of the rear crushing roller and the reciprocating screw are both fixedly connected to synchronous pulleys, and the two synchronous pulleys are connected by a synchronous belt. A first protective shell is fixedly connected between the right-side fixing groove and the housing, and the synchronous pulley is located inside the first protective shell.

[0011] Furthermore, a motor is installed on the right side of the housing, the right end of the front crushing roller is fixedly connected to the drive end of the motor, a gear is fixedly connected to the left end of the crushing roller, the two gears mesh with each other, and a second protective shell is fixedly connected to the left side of the crushing roller, with the gear located inside the second protective shell.

[0012] Furthermore, a collection box is provided on the bottom side inside the box, and a partition is fixedly connected inside the collection box.

[0013] This utility model has the following beneficial effects: 1. In this utility model, the edge material is magnetically separated by a magnet, thereby picking out internal metal impurities, reducing the pressure of subsequent manual sorting. By pulling the pull ring, the insert rod is pulled out of the magnet, and then the magnet is pulled out of the rotating plate, thus disassembling the magnet and making it convenient for workers to replace it.

[0014] 2. In this utility model, two synchronous pulleys connected by a synchronous belt drive a reciprocating screw to rotate, which in turn drives a scraper to move back and forth on the surface of a magnet, thereby scraping off metal objects or scraping them out of the box from the through slot and into the rear of the collection box or inside the collection container, thus collecting metal impurities.

[0017] 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.

[0018] Reference Figure 1 , Figure 2 and Figure 4 This utility model provides an embodiment of a device for recycling and reusing edge material from extruded polystyrene boards. The device includes a housing 1, with two guide plates 3 fixedly connected to both the front and rear sides inside the housing 1. Two crushing rollers 13 are rotatably connected inside the housing 1, positioned between the upper and lower guide plates 3. The guide plates 3 guide the edge material between the two crushing rollers 13 and control the edge material to fall towards the center of the housing 1. (See reference...) Figure 2 , Figure 4 and Figure 8 A rotating plate 9 is rotatably connected to the rear side of the housing 1 via a hinge. A magnet 19 is inserted inside the rotating plate 9. The magnet 19 attracts metal objects mixed in with the edge material, thus performing magnetic separation of the edge material. (Refer to...) Figure 9 and Figure 10 The rotating plate 9 has two insert rods 20 inserted inside, each passing through a magnet 19. A groove is formed at the top of each insert rod 20, and a fixing tube 21 is fixedly connected inside the groove. A pull ring 22 is rotatably connected inside the fixing tube 21. (Refer to...) Figure 2 and Figure 3 A fixing plate 10 is fixedly connected to the rear side of the housing 1 and the rotating plate 9. A positioning rod 11 is inserted between the two fixing plates 10. By pulling the positioning rod 11 off the two fixing plates 10, and then rotating the rotating plate 9 to expose the magnet 19, the pull ring 22 is pulled to pull the insertion rod 20 out of the magnet 19. Then the magnet 19 is pulled out of the rotating plate 9, and the magnet 19 is disassembled, which makes it convenient for the staff to replace the magnet 19. The insertion rod 20 is made of non-metallic material to prevent the magnet 19 from adhering to the insertion rod 20 and making it inconvenient to pull out the insertion rod 20.

[0019] Reference Figure 4 , Figure 5 and Figure 7 The box body 1 has fixed grooves 8 on its left and right sides. A scraper 16 is slidably connected inside the box body 1 and the fixed grooves 8. The rear side of the scraper 16 abuts against the front side of the magnet 19. Through slots are provided on both the left and right sides of the box body 1. Collection boxes 6 are provided on both the left and right sides of the box body 1. A reciprocating screw 15 is rotatably connected between the two fixed grooves 8. The top of the scraper 16 is sleeved on the outer wall of the reciprocating screw 15. Two rubber strips 18 are fixedly connected between the two fixed grooves 8. The working principle of the rubber strips 18 is as follows: when the scraper 16 moves to a certain position, the rubber strips 18 will be stretched open due to their elasticity, allowing the scraper 16 to move. The remaining positions of the rubber strips 18 will also automatically close due to their elasticity, thereby protecting the reciprocating screw 15 and preventing edge material from entering and affecting it. At the same time, the reciprocating screw 15 is coated with a protective coating to prevent it from being affected. (Refer to...) Figure 4 , Figure 6 and Figure 7Synchronous pulleys 17 are fixedly connected to the right ends of the rear crushing roller 13 and the reciprocating screw 15. The two synchronous pulleys 17 are connected by a synchronous belt. A first protective shell 5 is fixedly connected between the right fixed groove 8 and the housing 1. The synchronous pulleys 17 are located inside the first protective shell 5. A motor 4 is installed on the right side of the housing 1. The right end of the front crushing roller 13 is fixedly connected to the drive end of the motor 4. A gear 14 is fixedly connected to the left end of the crushing roller 13. The two gears 14 mesh with each other. A second protective shell 7 is fixedly connected to the left side of the crushing roller 13. Located inside the second protective shell 7, the 14 motor 4 drives the front crushing roller 13 to rotate, and the two meshing gears 14 drive the rear crushing roller 13 to rotate in opposite directions, thus crushing the edge material. Simultaneously, two synchronous pulleys 17 connected by synchronous belts drive the reciprocating screw 15 to rotate, causing the reciprocating screw 15 to drive the scraper 16 to move back and forth on the surface of the magnet 19, thereby scraping off metal objects or scraping them out of the slot from the box 1, and letting them fall into the rear of the collection box 6 or collection bin 2. The bottom of the box 1 is equipped with a collection bin 2, which is fixedly connected to a partition 12, dividing the collection bin 2 into two parts: one part collects the edge material, and the other part collects the metal impurities in the edge material.

[0020] Working principle: First, the scrap material is fed into the housing 1. Under the action of the guide plate 3, the scrap material enters between two crushing rollers 13. The motor 4 drives the front crushing roller 13 to rotate, and then the two meshing gears 14 drive the rear crushing roller 13 to rotate in opposite directions, thereby crushing the scrap material. Afterwards, the scrap material falls through the gap between the two crushing rollers 13. When it passes through the opposite area of ​​the magnet 19, the metal impurities in the scrap material will be attracted by the magnet 19, thus completing magnetic separation. Then the scrap material falls into the collection box 2, and is simultaneously discharged by two synchronous pulleys 17 connected by synchronous belts. The reciprocating screw 15 is driven to rotate, causing the scraper 16 to move back and forth on the surface of the magnet 19, thereby scraping off the metal object or scraping it out of the box 1 from the through groove, and letting it fall into the rear side of the collection box 6 or collection box 2. When the magnet 19 needs to be manually processed or maintained, the positioning rod 11 is pulled off the two fixing plates 10, and then the rotating plate 9 is rotated to expose the magnet 19. Then the pull ring 22 is pulled to pull it out of the magnet 19 along with the insertion rod 20. Then the magnet 19 is pulled out from the rotating plate 9, and then the magnet 19 can be disassembled. After that, the magnet 19 can be disassembled or maintained.

[0021] 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
