Description

Technical Field

[0001] This application relates to the field of 3D printers, and more particularly to a 3D printer waste sorting and recycling device. Background Technology

[0002] 3D printing technology has developed rapidly in recent years and is widely used in fields such as industrial manufacturing, medical care, and education.

[0003] With the widespread use of 3D printing equipment, the amount of waste generated during the printing process has also increased significantly. This waste mainly includes unused printing materials, support structures, and failed prints.

[0004] During the 3D printing process, various types of waste materials are conveyed out sequentially via a conveyor belt. The usual way to handle this is to discard or simply pile up the various types of waste materials together, which not only wastes resources but also pollutes the environment. Waste materials usually need to be recycled and collected, but there are many types of waste materials, and it is inconvenient to sort and recycle them when they are mixed together. Summary of the Invention

[0005] To address the problem of mixed collection of recycled waste materials, which makes sorting and recycling inconvenient, this application provides a 3D printer waste sorting and recycling device.

[0006] The 3D printer waste sorting and recycling device provided in this application adopts the following technical solution: A 3D printer waste sorting and recycling device includes a frame disposed on one side of the 3D printer's conveyor belt. A rotating disk for holding waste is rotatably mounted on the frame. A rotating component for driving the rotating disk is disposed on the frame. Multiple material cylinders are disposed on the frame and below the rotating disk, and the material cylinders are evenly spaced around the circumference of the rotating disk. Each material cylinder has an opening at its top. The rotating disk has a discharge hole corresponding to the opening. A scraping component for scraping the waste in the rotating disk is disposed on the frame. A multispectral sensor for identifying the type of waste and a control unit electrically connected to the multispectral sensor are disposed on the frame. The control unit is electrically connected to the rotating component.

[0007] By adopting the above technical solution, when the 3D printer sequentially transports each batch of waste material to the rotating disk via the conveyor belt, the multispectral sensor identifies the type of waste material in each batch. The control unit controls the rotating component to drive the rotating disk to rotate based on the identification results, so that the feeding hole is aligned with the corresponding material cylinder opening. The scraping component scrapes the waste material in the rotating disk into the material cylinder, thereby realizing the classification and recycling of waste materials.

[0008] Optionally, the frame is provided with a mounting bracket for placing the material cylinder, the rotating disk is rotatably connected to the mounting bracket, the frame is provided with a guide rod, a tray is slidably mounted on the frame in a direction toward or away from the mounting bracket, the material cylinder is placed on the upper side of the tray, the frame is provided with a lifting component for driving the tray to slide, and the tray is provided with a locking mechanism for connecting with the mounting bracket.

[0009] By adopting the above technical solution, the material cylinder is placed on the mounting frame and located on the upper side of the pallet. When the material cylinder needs to be replaced, the lifting component drives the pallet to slide and move the material cylinder out of the mounting frame. The new material cylinder is placed on the pallet, and the lifting component drives the material cylinder back to the mounting frame. The locking mechanism connects the pallet and the mounting frame, which can make the material cylinder installation more stable and facilitate the material cylinder replacement operation.

[0010] Optionally, the lifting component includes a lifting screw, a lifting motor, and a lifting plate. The lifting plate is slidably connected to the guide rod. The lifting screw is rotatably mounted on the frame and distributed parallel to the guide rod. The lifting motor is mounted on the frame. The lifting screw is connected to the output shaft of the lifting motor. The lifting plate is threadedly connected to the lifting screw. The tray is located on one side of the lifting plate.

[0011] By adopting the above technical solution, the lifting motor drives the lifting screw to rotate, which in turn causes the lifting plate to slide along the guide rod, thereby driving the pallet to move up and down, which facilitates the movement of the material cylinder.

[0012] Optionally, the locking mechanism includes a plug rod and a limiting member. The plug rod is slidably mounted on the tray. A slot is provided on the guide rod. One end of the plug rod is plugged into the guide rod through the slot. The limiting member is provided on the plug rod. A positioning post is provided on the mounting bracket. The limiting member is used to connect with the positioning post.

[0013] By adopting the above technical solution, when the material cylinder is located on the mounting frame, the tray is located on the lower side of the mounting frame. The insertion rod is inserted into the slot on the guide rod, and the limiting component is connected to the positioning column on the mounting frame to realize the connection between the tray and the mounting frame. The material cylinder is placed stably, ensuring that the position of the material cylinder is fixed during the operation of the waste sorting and recycling device.

[0014] Optionally, the limiting component includes a limiting plate and a limiting spring. The limiting spring is sleeved on the insert rod. The limiting plate is disposed at one end of the insert rod away from the guide rod and connected to one end of the limiting spring. The limiting plate is provided with a limiting hole. The positioning post is inserted and connected to the limiting plate through the limiting hole. The limiting plate is provided with a positioning component for positioning the positioning post.

[0015] By adopting the above technical solution, the limiting spring pulls one end of the insertion rod into the slot, and the limiting plate is inserted into the positioning post through the limiting hole. The positioning component can position the positioning post, so that the tray and the mounting frame can be stably connected, further ensuring the stability of the material cylinder placement.

[0016] Optionally, the positioning component includes a positioning rod and a positioning spring. The positioning rod is slidably mounted on the limiting plate in a direction toward or away from the positioning post. The positioning spring is sleeved on the positioning rod and connected to the limiting plate. The positioning post has a positioning groove, and one end of the positioning rod is inserted into the positioning post through the positioning groove.

[0017] By adopting the above technical solution, the positioning spring pulls the positioning rod to be inserted into the positioning groove, thereby positioning the limiting plate and the positioning column, making the connection between the pallet and the mounting frame more stable and ensuring the stable placement of the material cylinder.

[0018] Optionally, the rotating component includes a rotating motor, a gear, and a gear ring. The rotating motor is mounted on the frame, the gear is mounted on the output shaft of the rotating motor, and the rotating disk is coaxially mounted with a gear ring that meshes with one side of the gear. The rotating motor is electrically connected to the control unit.

[0019] By adopting the above technical solution, after the multispectral sensor identifies the type of waste, the control unit controls the operation of the rotating motor according to the identification result. The output shaft of the rotating motor drives the gear to rotate, and the gear meshes with the gear ring to make the rotating disk rotate, accurately conveying the waste in the rotating disk to the top of the corresponding material cylinder, thereby realizing the classified recycling of different types of waste.

[0020] Optionally, the scraping component includes a scraper and a scraping motor. The scraping motor is mounted on the rotating disk, and a rotating shaft is provided at the output shaft of the scraping motor. The scraper is mounted on the rotating shaft and is distributed perpendicularly to the rotating shaft. One side of the scraper is in contact with the inner wall of the rotating disk.

[0021] By adopting the above technical solution, the scraper motor drives the rotating shaft to rotate, which in turn drives the scraper to rotate, scraping the waste in the rotating disk, so that the waste falls into the corresponding material cylinder through the discharge hole, thereby achieving effective cleaning and classified recycling of waste.

[0022] Optionally, push bars are provided on opposite sides of the scraper along its length, the push bars are distributed along the length of the scraper, the push bars slide along the axis of the rotating shaft, and the scraper is provided with a pusher for pushing the push bars to slide.

[0023] By adopting the above technical solution, the pusher pushes the pusher strip to slide, and the sliding strip pushes the waste material adhering to the scraper to fall off, thereby reducing the adhesion of waste material to the scraper and improving the waste recycling efficiency.

[0024] Optionally, the pushing component includes a pushing spring and a pushing frame. The pushing frame is slidably mounted on the scraper along the axial direction of the rotating shaft. The pushing spring is disposed on one side of the scraper. The pushing frame is connected to the pushing spring, and the pushing bar is connected to one side of the pushing frame.

[0025] By adopting the above technical solution, pressing the pusher frame until the pusher spring is compressed causes the pusher frame to slide the pusher bar, thus better pushing the waste material. The pusher spring then drives the pusher frame back to its original position, facilitating the pusher cleaning process again.

[0026] In summary, this application includes at least one of the following beneficial technical effects: By using a multispectral sensor to identify the type of waste, the control unit controls the rotating part to drive the rotating disk to rotate, so that the feeding hole is aligned with the corresponding material cylinder opening, thus realizing the classification and recycling of waste and solving the problem of waste being mixed together and difficult to classify and recycle. The scraper scrapes the waste in the rotating disc, allowing the waste to fall smoothly through the discharge hole into the material cylinder, thus improving the waste recycling efficiency. The pallet can slide along the guide rod and be driven by the lifting device, which facilitates the installation and disassembly of the material cylinder and makes subsequent waste processing convenient.

[0035] The present application will be further described in detail below with reference to the accompanying drawings.

The frame 1 is located on one side of the conveyor belt of the 3D printer. The rotating disk 2 is horizontally mounted on the frame 1 to hold waste material. The rotating component 21 is mounted on the frame 1 to drive the rotating disk 2 to rotate. The material cylinder 3 is mounted on the frame 1 and located below the rotating disk 2. There are four material cylinders 3, which are evenly spaced around the circumference of the rotating disk 2. The top of the material cylinder 3 has an opening 31. The bottom wall of the rotating disk 2 has a discharge hole 24 corresponding to the opening 31. The scraper component 4 is mounted on the frame 1 to scrape the waste material in the rotating disk 2. The multispectral sensor 22 is mounted on the frame 1 to identify the type of waste material. The control unit 23 is electrically connected to the multispectral sensor 22 and the rotating component 21. When the 3D printer sequentially transports each batch of waste material to the rotating disk 2 via the conveyor belt, the multispectral sensor 22 can identify the type of waste material in each batch. The control unit 23 controls the rotating component 21 to drive the rotating disk 2 to rotate based on the identification result, so that the feeding hole 24 is aligned with the opening 31 of the corresponding material cylinder 3. The scraper component 4 scrapes the waste material in the rotating disk 2 into the material cylinder 3, thereby realizing the classification and recycling of waste material.

[0037] Reference Figure 1 and Figure 2 A cylindrical mounting bracket 11 is vertically mounted on the frame 1. The material cylinder 3 is inserted into the mounting bracket 11 in the vertical direction. The rotating disk 2 is disc-shaped and is coaxially mounted on the top of the mounting bracket 11 and located above the material cylinder 3.

[0038] Reference Figure 1 and Figure 2 The rotating component 21 includes a rotating motor 211, a gear 212, and a gear ring 213. The rotating motor 211 is mounted on the outer peripheral wall of the mounting bracket 11 with its output shaft vertically upward. The gear 212 is coaxially mounted on the output shaft of the rotating motor 211. The gear ring 213 is coaxially mounted on the outer peripheral wall of the rotating disk 2, and the gear ring 213 meshes with one side of the gear 212. The control unit 23 is mounted on the outer peripheral wall of the mounting bracket 11, and the rotating motor 211 is electrically connected to the control unit 23. When the rotating motor 211 is running, the output shaft drives the gear 212 to rotate, and the meshing of the gear 212 with the gear ring 213 causes the rotating disk 2 to rotate.

[0039] Reference Figure 1 and Figure 3 The scraper component 4 includes a scraper 41 and a scraper motor 42. A support frame 25 is provided on the rotating disk 2, and a multispectral sensor 22 is mounted on the support frame 25. A rotating shaft 26 is provided at the output shaft of the scraper motor 42. The rotating shaft 26 is coaxially distributed with the rotating disk 2. The scraper 41 is mounted on the rotating shaft 26 and is perpendicular to the rotating shaft 26. The downward side of the scraper 41 is in contact with the inner bottom wall of the rotating disk 2. When the scraper motor 42 drives the rotating shaft 26 to rotate, it drives the scraper 41 to rotate, thereby scraping the waste material in the rotating disk 2, causing the waste material to fall into the corresponding material cylinder 3 through the discharge hole 24.

[0040] Reference Figure 1 and Figure 3 Push bars 411 are provided on opposite sides along the length of the scraper 41. The push bars 411 are distributed along the length of the scraper 41 and slide vertically. A pusher 43 is provided on the scraper 41, including a push spring 431 and a pusher frame 432. The pusher frame 432 slides vertically on the scraper 41. The push spring 431 is located on the upward-facing side of the scraper 41. One side of the pusher frame 432 is connected to the upward-facing end of the push spring 431, and the push bars 411 are connected to one side of the pusher frame 432. When the pusher frame 432 is pressed, it compresses the push spring 431 and slides along the axis of the rotating shaft 26. The pusher frame 432 pushes the pusher bars 411 to slide, and the push bars 411 push the waste material adhering to the scraper 41 to fall off. When the pusher frame 432 is released, the push spring 431 drives the pusher frame 432 back to its original position, facilitating the next material pushing and cleaning operation.

[0041] Reference Figure 1 and Figure 2A multispectral sensor 22 is used to identify the type of waste. It can be mounted on the frame 1 near the rotating disk 2.

The control unit 23 is electrically connected to the multispectral sensor 22. The control unit 23 can be a microcontroller or a PLC controller. It receives the identification results from the multispectral sensor 22 and controls the rotating component 21 to drive the rotating disk 2 to rotate based on the identification results.

A guide block 131 is provided on one side of the tray 13. A vertical guide groove 121 is provided on the outer peripheral wall of the guide rod 12. The guide block 131 slides along the guide groove 121.

[0043] Reference Figure 2 and Figure 4 A lifting component 5 is installed on the frame 1. The lifting component 5 includes a lifting screw 51, a lifting motor 52, and a lifting plate 53. The lifting screw 51 is vertically rotatably mounted on the frame 1. The lifting motor 52 is mounted on the frame 1 and connected to the output shaft of the lifting screw 52. The lifting plate 53 is horizontally positioned and slidably connected to the guide rod 12. The lifting plate 53 is threadedly connected to the lifting screw 51. The tray 13 is positioned on the upward-facing side of the lifting plate 53. When the lifting motor 52 is running, the output shaft drives the lifting screw 51 to rotate. The threaded connection between the lifting plate 53 and the lifting screw 51 causes the lifting plate 53 to slide along the guide rod 12, thereby driving the tray 13 to move up and down.

[0044] Reference Figure 5 and Figure 6 The tray 13 is provided with a locking mechanism 6, which includes a plug rod 61 and a limiting member 62. The plug rod 61 is slidably installed on the tray 13 and slides in the direction toward or away from the guide rod 12. A slot 122 is provided on the outer peripheral wall of the upper end of the guide rod 12. One end of the plug rod 61 is inserted into the guide rod 12 through the slot 122.

[0045] Reference Figure 5 and Figure 6 The limiting component 62 is provided on the insertion rod 61. The limiting component 62 includes a limiting plate 621 and a limiting spring 622.

[0046] Reference Figure 5 and Figure 6 A positioning element 7 is provided on the limiting plate 621. The positioning element 7 includes a positioning rod 71 and a positioning spring 72. The positioning rod 71 is slidably installed on the limiting plate 621 in the vertical direction. The lower end of the positioning rod 71 is located at the limiting hole 6211 of the limiting plate 621. The positioning spring 72 is sleeved on the positioning rod 71 and connected to the limiting plate 621. A positioning groove 1111 is provided on the outer peripheral wall of the positioning post 111. The lower end of the positioning rod 71 is inserted and connected to the positioning post 111 through the positioning groove 1111.

[0047] When the material cylinder 3 needs to be replaced, the lifting component 5 moves the tray 13 to remove the material cylinder 3 from the mounting frame 11, and a new material cylinder 3 is placed on the tray 13. The lifting component 5 then moves the material cylinder 3 back to the mounting frame 11. Then, the locking mechanism 6 connects the tray 13 and the mounting frame 11, making the installation of the material cylinder 3 more secure.

[0048] The implementation principle of a 3D printer waste sorting and recycling device according to an embodiment of this application is as follows: The 3D printer sequentially transports batches of waste materials to the rotating disk 2 via a conveyor belt. A multispectral sensor 22 detects the reflection and absorption of light by the waste materials to identify the type of waste materials in each batch. The control unit 23 receives the identification results from the multispectral sensor 22. Based on the identification results, the control unit 23 sends a command to the rotating motor 211. The rotating motor 211 runs, and its output shaft drives the gear 212 to rotate. Through the meshing of the gear 212 and the gear ring 213, the rotating disk 2 rotates, aligning the discharge hole 24 on the rotating disk 2 with the opening 31 of the corresponding material cylinder 3. The scraper motor 42 runs, and its output shaft drives the rotating shaft 26 to rotate, which in turn drives the scraper 41 to rotate. The scraper 41 scrapes the waste materials in the rotating disk 2, causing the waste materials to fall into the corresponding material cylinder 3 through the discharge hole 24.

[0049] When the material cylinder 3 needs to be replaced, start the lifting motor 52. The output shaft of the lifting motor 52 drives the lifting screw 51 to rotate. Since the lifting plate 53 is threadedly connected to the lifting screw 51, the lifting plate 53 slides down along the guide rod 12, thereby moving the tray 13 downward and removing the material cylinder 3 from the mounting frame 11. Remove the old material cylinder 3 and place the new material cylinder 3 on the tray 13. Start the lifting motor 52 again, causing the lifting screw 51 to rotate in the opposite direction, driving the lifting plate 53 to slide upward along the guide rod 12, thereby moving the tray 13 and the material cylinder 3 back to the mounting frame 11. Slide the insertion rod 61 along the tray 13 so that one end is inserted into the slot 122 on the guide rod 12. Align the limiting hole 6211 on the limiting plate 621 with the positioning post 111 on the mounting bracket 11 and insert it. Under the action of the positioning spring 72, the positioning rod 71 slides towards the positioning post 111, so that one end of it is inserted into the positioning groove 1111 on the positioning post 111, thereby positioning the limiting plate 621 and the positioning post 111, and thus making the tray 13 and the mounting bracket 11 securely connected.

[0050] The scraper motor 42 operates, and its output shaft drives the rotating shaft 26 to rotate, which in turn drives the scraper 41 to rotate, scraping the waste material in the rotating disk 2. During this process, some waste material will adhere to the scraper 41. When it is necessary to clean the waste material adhering to the scraper 41, the pusher frame 432 is manually pressed. The pusher frame 432 slides along the axis of the rotating shaft 26 and compresses the push spring 431. The pusher frame 432 pushes the push bar 411 to slide along the axis of the rotating shaft 26, and the push bar 411 pushes the waste material adhering to the scraper 41 to fall off. Releasing the pusher frame 432 causes the push spring 431 to return to its original deformation, driving the pusher frame 432 back to its original position.

[0051] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
