Abstract
Description
Technical Field
[0001] This utility model belongs to the field of plastic raw material processing technology, and relates to the metal separation of plastic raw materials, particularly a metal separation device for plastic raw materials. Background Technology
[0002] Plastic raw materials generally refer to the basic raw materials used to manufacture various plastic products. During the raw material collection process, a large number of metal elements are mixed together, the most common of which is iron. Metal impurities may cause wear or damage to production equipment, increase maintenance costs, and affect the performance of plastic products, such as strength, toughness, and appearance, thus reducing the overall quality of the products. Therefore, it is necessary to use metal separation devices to separate the metal impurities contained in plastic raw materials. However, most existing metal separation devices still have problems that need to be solved.
[0003] Most existing metal separation devices use magnets to adsorb metal impurities, thus separating plastic from metal impurities. However, when plastic raw materials are piled up, the magnets are effective at adsorbing metal impurities on the surface, but metal impurities in the inner layers are difficult to adsorb. This requires workers to constantly turn the plastic raw materials over, which increases their workload to some extent. Therefore, it is necessary to design a metal separation device for plastic raw materials to solve the above problems. Utility Model Content
[0004] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a metal separation device for plastic raw materials. The technical problem this invention aims to solve is: how to remove metal impurities from plastic raw materials.
[0005] The objective of this utility model can be achieved through the following technical solutions:
[0006] A plastic raw material metal separation device includes a separation box. A support plate is fixedly connected to the inner wall of the separation box. Positioning rods are fixedly connected to both ends of the support plate. The two positioning rods are fitted onto the same frame. Holes adapted to the positioning rods are opened on the frame. A mesh bag is fixedly connected to the frame. A drive screw is provided at the top of the separation box, rotatably connected to the separation box. A screw nut is fitted onto the drive screw, adapted to the drive screw. A movable seat is fixedly connected to the outer wall of the screw nut. A U-shaped plate is fixedly connected to the bottom of the movable seat. A magnetic roller is rotatably connected to the U-shaped plate. A fixed plate is fixedly connected to one side of the U-shaped plate. A bearing is fixedly connected to the fixed plate. The outer ring of the bearing is fixedly connected to the fixed plate. A drive rod is fixedly connected to the inner wall of the bearing. A first gear is fixedly connected to one side of the drive rod, meshing with a first rack. The first rack is fixedly connected to the inner wall of the separation box. Several rubber hammers are fixedly connected to the outer wall of the drive rod.
[0007] The working principle of this utility model is as follows: The frame is positioned on the positioning rod, so that the rubber hammer is located at the inner edge of the separation box. When the drive screw rotates, it will drive the screw nut to rotate, which will drive the moving seat to move. The moving seat will drive the U-shaped plate to move, which will drive the magnetic roller to move. The movement of the U-shaped plate will also drive the fixed plate to move, which will drive the bearing to move. The bearing will drive the drive rod to move, which will drive the first gear to move. The first gear will move along the first rack and rotate during the movement. The rotation of the first gear will drive the drive rod to rotate, which will drive the rubber hammer to rotate. When the rubber hammer moves to the bottom of the net bag, its rotation will continuously strike the net bag, causing the net bag to shake and the plastic raw material on the net bag to turn up and spread out. The moving magnetic roller can then adsorb the metal in the plastic raw material, thus performing the metal separation work of the plastic raw material.
[0008] A second gear is fixedly connected to one side of the magnetic roller, and the second gear meshes with a second rack, which is fixedly connected to the inner wall of the separation box.
[0009] With the above structure, when the magnetic roller moves, it will also drive the second gear to move along the second rack, and the second gear will drive the magnetic roller to rotate to perform adsorption.
[0010] The separation box is equipped with two first guide rods inside. The first guide rods are fixedly connected to the inner wall of the separation box. Each of the two first guide rods is fitted with a first movable plate. The first movable plate is slidably connected to the first guide rod. Both first movable plates are fixedly connected to the top of the U-shaped plate.
[0011] With the above structure, when the U-shaped plate moves, it will drive the first moving plate to move along the first guide rod, ensuring the stability of the U-shaped plate when it moves.
[0012] A motor is fixedly connected to one side of the separation box, and the output end of the motor and the drive screw are connected by a coupling.
[0013] The separation box has an opening on one side, a door at the opening, an observation window on the door, and a handle fixedly connected to the door on the side away from the separation box.
[0014] With the above structure, the internal working conditions can be observed through the observation window.
[0015] Both ends of the box door are fixedly connected to a second movable plate on the side near the separation box. A second guide rod is passed through the second movable plate. The second movable plate is slidably connected to the second guide rod, and the second guide rod is fixedly connected to the separation box.
[0016] With the above structure, when the door is moved, the door will drive the second moving plate to move along the second guide rod, ensuring the stability of the door when it moves.
[0017] Compared with the prior art, the metal separation device for plastic raw materials of this utility model has the following advantages:
[0018] In this invention, the magnetic roller is used to strike the net bag during its movement. This striking action causes the plastic raw materials on the surface of the net bag to turn up and disperse, allowing metal impurities in the plastic raw materials to be lifted up and adsorbed by the magnetic roller. This effectively solves the problem mentioned in the background art that most existing metal separation devices do not achieve ideal results in separating metals from accumulated plastic raw materials. As a result, it reduces manual turning operations, effectively reduces the workload of workers, and improves the level of automation and production efficiency. Attached Figure Description

The frame 4 has holes that are adapted to the positioning rods 3. A mesh bag 5 is fixedly connected to the frame 4. A drive screw 6 is provided at the top of the separation box 1. The drive screw 6 is rotatably connected to the separation box 1. A screw nut 7 is fitted onto the drive screw 6. The screw nut 7 is adapted to the drive screw 6. A movable part is fixedly connected to the outer wall of the screw nut 7. The bottom of the movable seat 8 is fixedly connected to a U-shaped plate 9. A magnetic roller 10 is rotatably connected to the U-shaped plate 9. A fixing plate 11 is fixedly connected to one side of the U-shaped plate 9. A bearing 12 is fixedly connected to the fixing plate 11. The outer wall of the outer ring of the bearing 12 is fixedly connected to the fixing plate 11. The inner wall of the inner ring of the bearing 12 is fixedly connected to the drive rod 13. A first gear 14 is fixedly connected to one side of the drive rod 13. The first gear 14 meshes with a first rack 15. The first rack 15 is fixedly connected to the inner wall of the separation box 1. The outer wall of the drive rod 13 is fixedly connected to... There are several rubber hammers 16. A second gear 17 is fixedly connected to one side of the magnetic roller 10. The second gear 17 meshes with a second rack 18. The second rack 18 is fixedly connected to the inner wall of the separation box 1. Two first guide rods 20 are provided inside the separation box 1. The first guide rods 20 are fixedly connected to the inner wall of the separation box 1. Each of the two first guide rods 20 is fitted with a first movable plate 19. The first movable plate 19 is slidably connected to the first guide rod 20. Both first movable plates 19 are fixedly connected to the top of the U-shaped plate 9. One side of the separation box 1 is fixedly connected to... There is a motor 21, and the output end of the motor 21 is connected to the drive screw 6 through a coupling. The separation box 1 has an opening on one side, and the separation box 1 is provided with a door 22 at the opening. The door 22 is provided with an observation window 23. The door 22 is fixedly connected to a handle 24 on the side away from the separation box 1. The two ends of the door 22 are fixedly connected to a second moving plate 25 on the side close to the separation box 1. A second guide rod 26 passes through the second moving plate 25. The second moving plate 25 is slidably connected to the second guide rod 26. The second guide rod 26 is fixedly connected to the separation box 1.
[0027] The working principle of this utility model is as follows: When in use, an external power supply is used. The plastic raw material is placed on the mesh bag 5, and the frame 4 is placed on the positioning rod 3 for positioning, so that the rubber hammer 16 is located at the inner edge of the separation box 1. The motor 21 is started via an external controller. The output end of the motor 21 drives the coupling to rotate, which in turn drives the drive screw 6 to rotate. The rotation of the drive screw 6 drives the screw nut 7 to rotate, which in turn drives the moving seat 8 to move. The moving seat 8 then drives the U-shaped plate 9 to move. The movement of the U-shaped plate 9 causes the first moving plate 19 to move along the first guide rod 20, ensuring the stability of the U-shaped plate 9 during movement. The movement of the U-shaped plate 9 then drives the magnetic roller 10 to move. The movement of the magnetic roller 10 drives the second gear 17 to move along the second rack 18.

The rotation of the first gear 14 will drive the drive rod 13 to rotate, and the drive rod 13 will drive the rubber hammer 16 to rotate. When the rubber hammer 16 moves to the bottom of the net bag 5, its rotation will continuously strike the net bag 5, causing the net bag 5 to shake and the plastic raw material on the net bag 5 to turn up and scatter. The moving magnetic roller 10 can then adsorb the metal in the plastic raw material, performing the metal separation work. When the output end of the motor 21 rotates in the opposite direction, the magnetic roller 10 and the rubber hammer 16 can return to the initial position. By using the handle 24 to raise the box door 22, the frame 4 can be removed from the positioning rod 3, and the frame 4 and the net bag 5 can be taken out. The plastic material can then be processed, and the surface of the magnetic roller 10 can be scraped off with a scraper to remove the adsorbed metal.
