Description

Technical Field

[0001] This invention relates to the field of sorting machine technology, and more specifically to a sorting machine based on X-ray material identification. Background Technology

[0002] As is well known, material sorting mainly relies on differences in physical properties such as density, weight, color, optical properties, or magnetism to achieve differentiation. X-ray recognition-based sorting machines are intelligent equipment that use X-ray penetration imaging to analyze the differences in internal density and atomic number of materials to achieve high-precision automatic sorting.

[0003] A search revealed that Chinese patent application CN202511128371.2 discloses a laser-induced sorting machine, which is roughly described as follows: It includes an outer shell with a feed inlet at the top. A connecting strip is fixed inside the shell, and an inclined plate is located on the lower side of the connecting strip, with its right end tilting downwards. The inclined plate is positioned below the feed inlet. An inverted V-shaped component is fixed to the bottom of the inner shell, with an inverted V-shaped cross-section. A sorting plate is hinged to the upper part of the inverted V-shaped component. Arc-shaped grooves are provided on both the front and rear sides of the shell. Two convex cylinders are fixed to both the front and rear sides of the sorting plate, respectively, and are inserted into the two arc-shaped grooves. A base plate is fixed to the lower side of the shell, and support legs are fixed at the four corners of the lower side of the base plate. In use, it can identify objects by laser illumination and then perform sorting. The Chinese patent application CN202510841300.0 discloses a fluorescent sorting machine, which is roughly described as follows: It includes an inclined bucket with the left side higher than the right. An empty trough is provided on the left side of the inclined bucket. A long shaft is fixed to the lower side of the inclined bucket, and multiple baffles are rotatably connected to the long shaft, blocking the empty trough from front to back. A long seat is fixed to the lower side of the inclined bucket, and multiple control rods are slidably connected to the long seat. The control rods abut against the lower side of the baffles, and are driven to slide by cylinders. Support legs are fixed to both the front and rear sides of the inclined bucket. A second camera mount is fixed to the upper part of the inclined bucket, and multiple second cameras are arranged from front to back on the lower side of the second camera mount. During use, the multiple baffles fall down, emptying different positions in the empty trough, allowing particles to fall and completing the sorting.

[0004] While the aforementioned existing technical solutions can screen materials, both of them involve adjusting the spatial position and attitude of the corresponding material support parts to allow the materials to fall to different positions and ultimately achieve material sorting. Therefore, it is clear that the screening of materials relies too much on the material's own gravity, making it difficult to accurately control the falling material. The practicality of these solutions needs to be further improved. Summary of the Invention

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] For examples, please refer to Figures 1-19 A material sorting machine based on X-ray identification includes two inclined plates 1, a conveying structure, and a moving structure. The conveying structure includes a frame and a conveyor belt 2, with the conveyor belt 2 installed within the frame. The frame includes two end frames 20, with two upper sliding rods 21 and two lower sliding rods 22 fixedly connected between the two end frames 20.

A driving concave belt roller 33 and a driven concave belt roller 34 are rotatably connected to the two end frames 20 respectively. An auxiliary belt roller 35 is rotatably connected to each of the two end frames 20. The driving flat belt roller 31, the driven flat belt roller 32, the driving concave belt roller 33, the driven concave belt roller 34, and the two auxiliary belt rollers 35 are all connected to the conveyor belt 2. Two fourth servo motors 36 are installed on the outside of one of the rear end frames 20. 36 are used to drive the flat belt roller 31 and the concave belt roller 33 to rotate respectively. The conveyor belt 2 is made of a material that allows X-rays to pass through. Through the design of the conveying structure, it can actively convey the materials to be sorted and can be adapted to other components of the sorting system to efficiently build a complete sorting line to ensure the continuity and stability of the material sorting operation. The moving structure includes a moving frame 3 and a first servo motor 4. The moving frame 3 is slidably connected to the frame. The first servo motor 4 is installed outside the moving frame 3 and drives the moving frame 3 to slide relative to the frame. The moving frame 3 is equipped with multiple X-ray emitters 5 and multiple X-ray receivers 6. The multiple X-ray emitters 5 are matched with the multiple X-ray receivers 6 respectively. The moving frame 3 is fixedly connected with an outer upper tilting plate 37 and a middle upper tilting plate 38. The outer upper tilting plate 37 is provided with mounting holes that match the X-ray emitters 5, and the middle upper tilting plate 38 is provided with mounting holes that match the X-ray receivers 6. The middle upper tilting plate 38 is located inside the belt loop of the conveyor belt 2, and the outer upper tilting plate 37 is located above the conveyor belt 2.

[0041] It should be further explained that a mounting cylinder 7 is fixedly connected to the top of the movable frame 3, a rotating cylinder 8 is rotatably connected inside the mounting cylinder 7, and a rotating shaft 9 is rotatably connected inside the rotating cylinder 8. A second servo motor 10 and a third servo motor 11 are mounted outside the mounting cylinder 7. The second servo motor 10 and the third servo motor 11 are used to drive the rotation of the rotating cylinder 8 and the rotating shaft 9, respectively. Both the rotating cylinder 8 and the rotating shaft 9 are equipped with triangular shovels 12 via telescopic components. The two triangular shovels 12 are matched with each other. The two telescopic components include an inner mounting sleeve 13 and an outer mounting sleeve 14, which are fixedly connected to the rotating shaft 9 and the rotating cylinder 8, respectively. Both the inner mounting sleeve 13 and the outer mounting sleeve 14 are slidably connected to sliding frames 15. The two sliding frames 15 are respectively connected to the two triangular shovels 9 and the rotating shaft 9. The shovel 12 is fixedly connected. Both the inner mounting sleeve 13 and the outer mounting sleeve 14 are equipped with electric telescopic rods 16. Each of the two electric telescopic rods 16 is connected to a transmission plate 17. The two transmission plates 17 are fixedly connected to two sliding frames 15. Both the inner mounting sleeve 13 and the outer mounting sleeve 14 are fixedly connected to an extension frame 18. The two electric telescopic rods 16 are installed under the two extension frames 18. Both the inner mounting sleeve 13 and the outer mounting sleeve 14 have strip-shaped through-holes 19, which are used for the passage of the two transmission plates 17. Through the design of the moving structure, suitable installation positions can be provided for the radiation emitter 5 and the radiation receiver 6, thereby facilitating the execution of adaptive sorting actions based on the material identification results, effectively improving the operation of the entire sorting system. The flexibility significantly enhances the practicality of the sorting machine. Both inclined plates 1 are fixedly connected to the moving frame 3. The mounting cylinder 7 is fixedly connected to two side support inclined frames 25, both of which are fixedly connected to the top of the moving frame 3. The rotating cylinder 8 is provided with an upper boss 26 and a lower boss 27. The second servo motor 10 is fixedly mounted on the upper boss 26 via an upper sleeve pressure frame, and the third servo motor 11 is fixedly mounted below the lower boss 27 via a lower sleeve pressure frame. A longitudinal rack 28 is fixedly connected between the two end frames 20. Both the rotating cylinder 8 and the rotating shaft 9 are fixedly connected to transmission gear rings 29. The longitudinal rack 28 and the two transmission gear rings 29 are meshed with transmission gears 30, which are respectively connected to the first servo motor 4, the second servo motor 10, and the third servo motor 11. The output shaft of the servo motor 11 is connected to the drive concave belt roller 33 and the driven concave belt roller 34, both of which are equipped with rounded-edge support rotating surfaces. These surfaces are used to support the deformation of the conveyor belt 2. The drive flat belt roller 31 and the driven flat belt roller 32 are both equipped with limiting protrusions 39 that match the conveyor belt 2. These limiting protrusions 39 can guide the movement of the conveyor belt 2 and reduce its lateral deviation. When the conveyor belt 2 enters the support area of ​​the rounded-edge support rotating surface, it will be pressed against the surface by the material on the upper side of the conveyor belt 2 and its own weight. This ensures that the conveyor belt 2 enters the working area corresponding to the triangular shovel 12 and can adapt to the triangular shovel 12 with different rotation angles, ensuring a good fit between the bottom of the triangular shovel 12 and the conveyor belt 2.Each end of the two end frames 20, the two upper sliding rods 21, and the two lower sliding rods 22 is provided with an assembly opening 40. The two mating assembly openings 40 are fixedly connected by assembly bolts 41. The movable frame 3 is fixedly connected to two covering frames 42, each of which is fixedly connected to a support hanger 43. The two support hangers 43 are respectively fixedly connected to two long sliding sleeves 23. Two inclined plates 1 are respectively fixedly connected to the support hangers 43 and also to the two covering frames 42. The inclined plates 1 are used to receive and guide the material pushed out by the triangular shovel 12 relative to the conveyor belt 2, ultimately facilitating the collection of sorted materials.

[0042] In this embodiment, the first servo motor 4, the ray emitter 5, the ray receiver 6, the second servo motor 10, the third servo motor 11, the electric telescopic rod 16, and the fourth servo motor 36 are all commercially available conventional devices known to those skilled in the art. In this invention, we are simply using them without making any improvements to their structure or function. Their setting methods, installation methods, and electrical connection methods can be easily understood by those skilled in the art by following the instructions for use, and will not be described in detail here.

[0043] In summary, the working principle of this X-ray-based material sorting machine is as follows: First, a controller is installed to support the first servo motor 4, the X-ray emitter 5, the X-ray receiver 6, the second servo motor 10, the third servo motor 11, the electric telescopic rod 16, and the fourth servo motor 36. Next, a control circuit is installed on the controller. By connecting the power to the control circuit, the controller can operate. The controller controls the operation of the first servo motor 4, the X-ray emitter 5, the X-ray receiver 6, the second servo motor 10, the third servo motor 11, the electric telescopic rod 16, and the fourth servo motor 36. After installation, the X-ray intensity and emission frequency of the X-ray emitter 5 and the signal sensitivity of the X-ray receiver 6 are adjusted to ensure accurate capture of the image after X-rays penetrate the material. The signal is then set, and the target material parameters such as density threshold and atomic number range are set. All preparations before the operation are completed. After the preparations are completed, the sorting machine is started, and the material sorting operation process officially begins. First, the two fourth servo motors 36 are started. The two fourth servo motors 36 drive the driving flat belt roller 31 and the driving concave belt roller 33 to rotate respectively. Under the coordinated transmission of the driving flat belt roller 31, driven flat belt roller 32, driving concave belt roller 33, driven concave belt roller 34 and two auxiliary belt rollers 35, the conveyor belt 2 starts to run smoothly at the set speed. Then, the material to be screened is evenly fed onto the conveyor belt 2. The material feeding area should be located on the conveyor belt 2 inside the front end frame. Under the drive of the conveyor belt 2, the material moves smoothly along the conveying direction of the conveyor belt 2 and gradually enters the X-ray identification area.

[0044] When the material enters the X-ray identification area, multiple X-ray emitters 5 are activated simultaneously, emitting X-rays into the material. After penetrating the material, the X-rays are received by the corresponding X-ray receivers 6. Due to differences in internal density or atomic number among different materials, the attenuation of X-rays varies when penetrating different materials. The X-ray receivers 6 convert the received attenuated X-ray signals into electrical signals and transmit them to the controller. The controller performs real-time analysis and processing of the electrical signals, and quickly identifies target and non-target materials by comparing them with preset target material parameters. It also accurately locates the specific position of each target material on the conveyor belt 2. Simultaneously, it transmits the positioning information and sorting instructions to the moving structure and sorting execution components to ensure that the sorting action is precisely matched with the material movement rhythm. After the X-rays identify the target material, the first servo motor 4 is activated simultaneously, causing the drive frame 3 to slide along the upper sliding rod 21 and the lower sliding rod 22 via the long sliding sleeve 23 and the short sliding sleeve 24, respectively. This ensures that the sliding speed of the moving frame 3 is synchronized with the conveying speed of the conveyor belt 2, ensuring that the X-ray emitters 5 and the X-ray receivers 6 are synchronized. The X-ray receiver 6 is always aligned with the identified target material until the target material in the corresponding detection area of ​​the X-ray emitter 5 and the X-ray receiver 6 on the conveyor belt 2 is completely separated. At the same time, the second servo motor 10, the third servo motor 11 and the electric telescopic rod 16 start synchronously to begin the sorting operation. The second servo motor 10 and the third servo motor 11 drive the rotating cylinder 8 and the rotating shaft 9 to rotate in the mounting cylinder 7 according to the position and direction of the target material. The rotation angle of the rotating cylinder 8 and the rotating shaft 9 changes, thereby changing the relative position of the two triangular shovels 12, so that the concave structure on the front of the triangular shovels 12 is aligned with the target material. Then the electric telescopic rod 16 runs, driving the transmission plate 17 to slide along the strip through-hole 19. The transmission plate 17 drives the sliding frame 15 to slide in the inner mounting sleeve 13 or the outer mounting sleeve 14, thereby adjusting the extension stroke of the two triangular shovels 12, so that the triangular shovels 12 are adapted to the target material, ensuring that the target material can be driven stably. At the same time, the bottom of the triangular shovels 12 is in contact with the surface of the conveyor belt 2 to prevent the material from slipping out of the gap between the triangular shovels 12 and the conveyor belt 2.

[0045] Depending on the distribution of the target material, the two triangular shovels 12 can be used individually or in combination. If the target material is located in the middle of the conveyor belt 2, one of the triangular shovels 12 can be rotated to the target material position first. The concave structure on the front of the triangular shovel 12 receives and pushes the target material. At the same time, the other triangular shovel 12 fits against the first one. The concave structures on the front of the two triangular shovels 12 fit together to form a closed receiving space, enclosing the target material within the receiving space, thus isolating the target material and preventing it from mixing with non-target materials. Furthermore, during the synchronous swing of the two triangular shovels 12, the raised structure on the back of the triangular shovels 12 can push non-target materials to the side, preventing them from being missorted. If the target material covers a large area or consists of multiple areas, the two triangular shovels 12 can be controlled to run repeatedly until the target material is completely separated. If the target material is close to the side of the conveyor belt 2, it can be directly pushed outward by the recessed structure of a single triangular shovel 12 onto the side of the conveyor belt 2. The pushed-out target material is received by the inclined plates 1 located on both sides of the moving frame 3. Guided by the conveyor belt 2, the material finally falls into the preset target material collection area, completing the sorting and collection of the target material. Non-target materials that are not identified as target materials continue to move along the conveying direction under the drive of the conveyor belt 2. After passing through the sorting area, they fall into the non-target material collection area from the rear discharge end of the conveyor belt 2, achieving complete separation of target materials and non-target materials. During the sorting process, the conveyor belt 2 always maintains a constant speed. When the material in a section of the conveyor belt 2 is sorted, the moving frame 3 no longer moves synchronously with the conveyor belt 2. The moving frame 3 moves forward relative to the conveyor belt 2 through the operation control of the first servo motor 4 to match the material on the conveyor belt 2 to form a sequential sorting. In this way, the stable operation of the conveyor belt 2 can be guaranteed, reducing the speed change or frequent start and stop of the conveyor belt 2. At the same time, it can also adapt to the distribution of target materials in different areas of the conveyor belt 2. When there are fewer target materials in a certain section of the conveyor belt 2, the moving frame 3 can make a short stop in the area with fewer target materials and spend more time in the area with more target materials, thereby achieving optimized time allocation in the material sorting operation.

[0046] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
