[0002] The recycling and processing of waste circuit boards is an important part of the resource utilization of electronic waste, and its sorting technology is directly related to the recycling efficiency and environmental friendliness of metallic and non-metallic components.

[0003] A search revealed a Chinese patent with publication number CN214917058U, which discloses a circuit board sorting device. This device uses a plate-type magnetic separator, where movable magnetic blocks can be inserted into the material for magnetic separation. The magnetic separation efficiency is high, and the screened material contains few impurities. However, the entire magnetic separation belt of this device is equipped with magnetic blocks, which cannot ensure that the adsorbed material is completely removed from the magnetic separation belt. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a waste circuit board sorting device to solve the problems existing in the background art.

[0005] This utility model provides the following technical solution: a waste circuit board sorting device, comprising two conveying devices, two first fixing plates fixedly connected symmetrically to the upper surfaces of the two conveying devices, a rotating roller rotatably connected between the two first fixing plates on the same conveying device, the two rotating rollers being connected by a conveyor belt, a drive motor for axial rotation of the rotating roller being provided on one side of one of the first fixing plates, a plurality of second fixing plates fixedly connected to the upper surfaces of the two conveying devices, a connecting plate passing through the conveyor belt being fixedly connected between the plurality of second fixing plates, a magnetic block in contact with the conveyor belt being provided on the lower surface of the connecting plate, a scraping component for scraping off residual material being provided between one of the conveying devices and the conveyor belt, a receiving component being provided between the two second fixing plates, and a collection component for collecting waste material being provided between the two conveying devices.

[0006] As a further embodiment of this utility model, the scraping component includes two fixed blocks that are fixedly connected to one of the conveying devices and are symmetrically located on the non-magnetic block part below the conveyor belt. Each of the two fixed blocks has a limit port, and each of the two limit ports has a slider that is slidably connected to it. A scraper that contacts the bottom of the conveyor belt is fixedly connected between the two sliders.

[0007] As a further embodiment of this utility model, the receiving assembly includes two crossbars fixedly connected between two sets of second fixed plates, and an inclined plate that tilts downward toward the second conveying device is fixedly connected between the two crossbars, with the lower end of the inclined plate above the second conveying device.

[0008] As a further embodiment of this utility model, the collection assembly includes a fixed bracket fixedly connected between two conveying devices, a collection box slidably connected to the fixed bracket, and a handle fixedly connected to one side of the collection box.

[0009] As a further embodiment of this utility model, a spring is fixedly connected to the lower surface of the slider, and the other end of the spring is fixed to the bottom inner wall of the limiting port.

[0010] As a further embodiment of this utility model, a portion of the connecting plate is located on the first conveying device, and another portion is located on the second conveying device, with a gap between the right end of the connecting plate and the right end of the conveyor belt.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] 1. This utility model uses a magnetic block to attract metal blocks from the conveyor belt as it passes the first conveyor device. When the metal blocks leave the magnetic block's range, they are placed on the second conveyor device, where they are transported. This ensures that the attracted material leaves the conveyor belt, while the remaining waste is sent to the collection assembly by the first conveyor device for centralized processing.

[0013] 2. This utility model, through its scraping component, can scrape the surface of the conveyor belt after the adsorbed material separates from the conveyor belt, thereby removing the residual debris on the surface of the conveyor belt, thus ensuring the cleanliness of the conveyor belt surface and its normal use.

[0014] 3. The present invention has a collection component that can collect adsorbent material that falls off on its own when the conveyor belt passes between two conveying devices, thereby preventing it from falling into the collection component. Attached Figure Description

[0021] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. This utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Reference Figures 1-5 This utility model provides a waste circuit board sorting device, including two conveying devices 1. Two first fixing plates 2 are symmetrically fixed to the upper surfaces of the two conveying devices 1 by bolts. Rotating rollers 3 are rotatably connected between the two first fixing plates 2 on the same conveying device 1. The two rotating rollers 3 are connected by a conveyor belt 4. A drive motor 5 for axial rotation of the rotating roller 3 is provided on one side of one of the first fixing plates 2. Multiple second fixing plates 6 are fixed to the upper surfaces of the two conveying devices 1 by bolts. Connecting plates 7 passing through the conveyor belt 4 are fixed to the multiple second fixing plates 6 by bolts. The lower surface of the connecting plate 7... A magnetic block 11 is provided that contacts the conveyor belt 4. A scraping component 10 for scraping off residual material is provided between one of the conveying devices 1 and the conveyor belt 4. A receiving component 9 is provided between the two second fixed plates 6. A collection component 8 for collecting waste material is provided between the two conveying devices 1. The magnetic block 11 can adsorb metal blocks in the conveyed material of the conveyor belt 4 onto the surface of the conveyor belt 4 when the conveyor belt 4 passes the first conveyor device 1. When the metal blocks leave the range of the magnetic block 11, they are placed on the second conveyor device 1 and the metal objects fall off and are conveyed on the second conveyor device 1, ensuring that the adsorbed material leaves the conveyor belt 4. The remaining waste material is sent to the collection component 8 by the first conveyor device 1 for centralized processing.

[0023] In this invention, the scraping assembly 10 includes two symmetrical fixing blocks 14 that are bolted to one of the conveying devices 1 and located on the non-magnetic block 11 below the conveyor belt 4. Each fixing block 14 has a limiting port 15, and each limiting port 15 has a sliding block 16 slidably connected to it. A scraper 18 that contacts the bottom of the conveyor belt 4 is bolted between the two sliding blocks 16. With the scraping assembly 10, the surface of the conveyor belt 4 can be scraped after the adsorbed material is separated from the conveyor belt 4, thereby removing the residual debris on the surface of the conveyor belt 4, thus making the surface of the conveyor belt 4 clean and ensuring its normal use.

[0024] To prevent metal objects from falling into the collection assembly 8, the receiving assembly 9 includes two crossbars 12 bolted between two sets of second fixed plates 6. An inclined plate 13, tilting downwards towards the second conveying device 1, is bolted between the two crossbars 12, with the lower end of the inclined plate 13 positioned above the second conveying device 1. The collection assembly 8 can collect any adsorbent material that falls off when the conveyor belt 4 passes between the two conveying devices 1, thus preventing it from falling into the collection assembly 8. The collection assembly 8 includes a fixed bracket 19 bolted between the two conveying devices 1. A collection box 20 is slidably connected to the fixed bracket 19, and a handle is bolted to one side of the collection box 20. The collection assembly 8 can collect and process the waste material conveyed by the first conveying device 1, preventing it from falling to the ground and requiring secondary manual processing, thus saving time.

[0025] To ensure that the scraper 18 is in close contact with the conveyor belt 4, a spring 17 is fixedly connected to the lower surface of the slider 16 by bolts, and the other end of the spring 17 is fixed to the bottom inner wall of the limiting port 15. The spring 17 can apply force to the slider 16 to make the scraper 18 in close contact with the surface of the conveyor belt 4. Most of the connecting plate 7 is located on the first conveying device 1, and a small part is located on the second conveying device 1. There is a gap between the right end of the connecting plate 7 and the right end of the conveyor belt 4.

[0026] The use of this utility model involves the following steps:

[0027] S1: When it is necessary to magnetically attract circuit board fragments, the fragments are first evenly placed on the first conveyor device 1. After passing under the conveyor belt 4, the magnetic block 11 attracts the metal objects on it to the conveyor belt 4 for conveying. When the conveyor belt 4 leaves the range of the magnetic block 11, the adsorbed objects on it fall off by themselves and fall to the second conveyor device 1 for conveying. The remaining waste is conveyed to the collection component 8 through the first conveyor device 1.

[0028] S2: After the adsorbent separates from the conveyor belt 4, the conveyor belt 4 passes through the scraper 18 on the scraping assembly 10 to scrape its surface, thereby ensuring that the debris on the conveyor belt 4 is completely scraped off and ensuring the cleanliness of the surface of the conveyor belt 4.

[0029] Finally, the following points should be noted: In the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection" and "linkage" should be interpreted broadly, and can be mechanical or electrical connection, or internal connection between two components, or direct connection. "Up", "down", "left", "right", etc. are only used to indicate relative positional relationship. When the absolute position of the described object changes, the relative positional relationship may change.
