Description

Technical Field

[0001] This utility model relates to the field of aluminum shot sorting technology, specifically to an aluminum shot particle size sorting and receiving device. Background Technology

[0002] Aluminum shot particle size sorting and receiving devices are crucial equipment in aluminum processing and related applications, ensuring the uniformity of aluminum shot quality and playing an indispensable role in modern industrial production processes. This device is primarily used to precisely classify and screen aluminum shot of mixed particle sizes according to specific particle size standards, collecting aluminum shot from different particle size ranges separately. In metal surface treatment processes such as shot blasting and sandblasting, aluminum shot of different sizes produces significantly different surface treatment effects. By using an aluminum shot particle size sorting and receiving device, precisely matched aluminum shot can be provided for these processes, ensuring that the metal surface achieves the expected roughness, cleanliness, and residual stress distribution, thereby improving the quality and service life of metal products.

[0003] For example, the Chinese authorized patent CN218223504U, entitled "An Aluminum Shot Particle Size Sorting Device", includes an outer box and an inner cylinder. The inner cylinder is placed inside the outer box. A rotary motor is installed at the bottom of the outer box, and the inner cylinder is placed on the rotary motor. A partition plate is installed between the outer box and the inner cylinder. A gap is reserved between the inner edge of the partition plate and the surface of the inner cylinder. Multiple outlet pipes are installed on the side wall of the outer box. The outlet pipes correspond to the partition plate. The inner cylinder is narrow at the bottom and wide at the top, and has two steps. The two steps divide the inner cylinder into an upper sorting layer, a middle sorting layer, and a lower sorting layer. The multi-level sorting layers perform centrifugal stratification of aluminum shot, and are classified and stored in conjunction with corresponding sorting holes.

[0004] While the existing technology can sort aluminum shot according to its diameter, during the sorting process, some larger aluminum shot may get stuck in the fine holes, preventing smaller aluminum shot from being discharged. As a result, a small amount of aluminum shot remains inside the device after the equipment is shut down, which does not meet the current requirements. To address this, we propose an aluminum shot particle size sorting and receiving device. Utility Model Content

[0005] The purpose of this invention is to provide an aluminum shot particle size sorting and receiving device to solve the problem mentioned in the background art where some larger aluminum shots get stuck in the fine holes during the sorting process, preventing smaller aluminum shots from being discharged.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an aluminum shot particle size sorting and receiving device, comprising a shell, a back plate welded and fixed to the back of the shell, three inclined sorting discs inside the shell, a turntable rotatably mounted on the upper end inside the back plate, a connecting arm mounted at the eccentric position of the front end of the turntable, the connecting arm being connected to the turntable via a rotating shaft, a lifting rod mounted on the lower end of the connecting arm, the outer wall of the lifting rod slidingly limiting the back plate, and the upper end of the lifting rod being connected to the connecting arm via a rotating shaft, the two sides of the front end of the sorting disc being connected to the shell via a rotating shaft, an adjusting frame being provided behind the sorting disc, a connecting plate being fixedly provided between the upper and lower adjusting frames, and the upper end face of the upper adjusting frame being fixed to the lower end of the lifting rod, a drive motor being fixedly mounted at the rear end of the back plate, and the output shaft of the drive motor being fixed to the shaft at the rear end of the turntable.

[0007] Preferably, the front end face of the back plate is provided with three sets of limiting slide grooves, the adjustment frame is located inside the limiting slide grooves, and the two sides of the adjustment frame slide and limit the movement of the limiting slide grooves.

[0008] Preferably, a movable plate is installed at the rear end of the sorting disc, and the movable plate is slidably engaged with the sorting disc. Movable shafts are installed on both sides of the movable plate, and the movable shafts are rotatably engaged with the adjusting frame.

[0009] Preferably, both sides of the movable plate are provided with sliding grooves, one end of the movable shaft extends into the interior of the sliding groove, and the movable shaft slides in cooperation with the sliding groove. The inner side of the adjustment frame side plate is provided with multiple vertically distributed insertion holes, and one end of the movable shaft is inserted into the insertion hole. A spring is installed between the movable shaft and the sliding groove, and a lever plate that slides in cooperation with the movable plate is fixedly provided at the upper end of the movable shaft.

[0010] Preferably, the aperture of the sorting disc gradually decreases from top to bottom.

[0011] Preferably, an inclined guide plate is installed at the front end below the sorting plate, and the two sides of the guide plate are fixed to the outer shell by screws, and the guide plate extends to the front of the outer shell.

[0012] Preferably, a dust collection hood is installed on one side of the outer shell and is connected to the inner cavity of the outer shell; a dust collection box is installed on the back of the outer shell and a dust collection pipe is installed between the dust collection box and the dust collection hood; and a negative pressure fan is installed on one side of the dust collection box.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model employs a vibrating sieve disc to sort aluminum shot. A drive motor rotates the disc, and an eccentric connecting arm induces the vertical reciprocating motion of the lifting rod, achieving high-frequency vibration of the sorting disc. This vibration mechanism efficiently separates aluminum shot of different sizes, ensuring effective separation of large-diameter and small-diameter shot. The inclined design of the sorting disc helps large-diameter shot gradually move towards the front and be discharged under vibration, while small-diameter shot can smoothly pass through this layer of the sorting disc for further sorting. This design allows the device to adapt to the sorting needs of aluminum shot within different particle size ranges. Through precise sorting, the device ensures the consistency and uniformity of aluminum shot particle size, thereby improving the quality of the final product and preventing some larger aluminum shot from getting stuck in the fine holes, preventing smaller-diameter shot from being discharged.

[0015] 2. This utility model features a sorting disc angle adjustment mechanism. By pulling the lever inward, the user extends the movable shaft into the chute, causing one end of the movable shaft to separate from the insertion hole on the adjustment frame. At this point, the adjustment frame loses its limiting effect on the sorting disc, allowing the angle of the sorting disc to be adjusted. After adjusting to the designated position, the lever is released, and the movable shaft is re-inserted into the insertion hole by the elasticity of the spring inside the chute, thus limiting the sorting disc at that tilt angle. Different tilt angles affect the movement trajectory and separation efficiency of the aluminum shot on the sorting disc. By adjusting the angle of the sorting disc, the sorting process can be further optimized, ensuring that large-diameter aluminum shot can move smoothly towards the front end and be discharged, while small-diameter aluminum shot can pass through smoothly for the next round of sorting, thereby improving sorting efficiency and accuracy.

[0016] 3. This utility model has a dust suction hood installed on one side of the outer shell. During the sorting process, the negative pressure fan is turned on to quickly exhaust the air inside the dust collection box. At the same time, the air outside the dust suction hood is continuously replenished into the negative pressure fan, forming a high pressure difference with the outside. Thus, the dust generated by the vibration and contact of the aluminum shot inside the outer shell is sucked into the dust collection box with the air, thereby ensuring the cleanliness of the sorting process.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Please see Figure 1-4 This utility model provides an embodiment of an aluminum shot particle size sorting and receiving device, comprising a housing 1, a back plate 3 welded and fixed to the back of the housing 1, three inclined sorting discs 8 inside the housing 1, the aperture of the sorting discs 8 gradually decreasing from top to bottom, a turntable 5 rotatably mounted on the upper end inside the back plate 3, a connecting arm 6 mounted at the eccentric position of the front end of the turntable 5, and the connecting arm 6 connected to the turntable via a rotating shaft, a lifting rod 7 mounted on the lower end of the connecting arm 6, the outer wall of the lifting rod 7 slidingly limiting the back plate 3, and the upper end of the lifting rod 7 connecting the connecting arm 5... 6. The two sides of the front end of the sorting disk 8 are connected to the outer shell 1 via a rotating shaft. An adjustment frame 14 is provided at the rear of the sorting disk 8. A connecting plate 15 is fixedly provided between the upper and lower adjustment frames 14. The upper end face of the upper adjustment frame 14 is fixed to the lower end of the lifting rod 7. A drive motor 4 is fixedly installed at the rear end of the back plate 3. The output shaft of the drive motor 4 is fixed to the shaft at the rear end of the turntable 5. Three sets of limiting slide grooves 13 are provided on the front end face of the back plate 3. The adjustment frame 14 is located inside the limiting slide groove 13. The two sides of the adjustment frame 14 slide and limit the movement of the limiting slide groove 13.

[0024] In use, by turning on the drive motor 4, its output shaft drives the turntable 5 to rotate. Since the connecting arm 6 is eccentrically mounted, the upper end of the connecting arm 6 will move in a circular motion relative to the center of the turntable 5, and its lower end will move along an approximately arc-shaped trajectory. The vertical component of the arc-shaped trajectory causes the lifting rod 7 to slide up and down in the back plate 3. When the lower end of the connecting arm 6 moves upward, it pushes the lifting rod 7 to slide upward; when the lower end of the connecting arm 6 moves downward, the lifting rod 7 will slide downward under the action of gravity. As the turntable 5 continues to rotate, the lifting rod 7 will achieve continuous vertical reciprocating motion in the back plate 3. The lower end of the lifting rod 7 is connected to the sorting plate 8, forming a high-frequency vibration of the sorting plate 8. After the aluminum shot is poured into the inner shell 1 from the feed port 2, under the action of vibration, the large-diameter aluminum shot is blocked at the upper end. The sorting plate 8 is designed to be inclined. Under the action of vibration, the large-diameter aluminum shot gradually moves towards the front end until it falls into the guide plate 9 and is discharged. The small-diameter aluminum shot passes through the sorting plate 8 and continues to be sorted.

[0025] Please see Figure 2 and Figure 3 A movable plate 16 is installed at the rear end of the sorting plate 8, and the movable plate 16 is slidably engaged with the sorting plate 8. Movable shafts 17 are installed on both sides of the movable plate 16, and the movable shafts 17 are rotatably engaged with the adjusting frame 14. Slide grooves 18 are provided on both sides inside the movable plate 16. One end of the movable shaft 17 extends into the interior of the slide groove 18, and the movable shaft 17 is slidably engaged with the slide groove 18. Multiple vertically distributed insertion holes 20 are provided on the inner side of the side plate of the adjusting frame 14, and one end of the movable shaft 17 is inserted into the insertion hole 20. A spring is installed between the movable shaft 17 and the slide groove 18. A lever 19 that is slidably engaged with the movable plate 16 is fixedly installed at the upper end of the movable shaft 17.

[0026] The user pulls the lever 19 inward, causing the movable shaft 17 to extend into the slide groove 18, thereby separating one end of the movable shaft 17 from the insertion hole 20 on the adjusting frame 14. At this time, the adjusting frame 14 loses its limit on the sorting disk 8, thus allowing the angle of the sorting disk 8 to be adjusted. After adjusting to the designated position, the lever 19 is released, and under the elasticity of the spring inside the slide groove 18, the movable shaft 17 is inserted back into the insertion hole 20, realizing the limit of the sorting disk 8 at that tilt angle. Different tilt angles will affect the movement trajectory and separation efficiency of the aluminum shot on the sorting disk 8. By adjusting the angle of the sorting disk 8, the sorting process can be further optimized, ensuring that large-diameter aluminum shot can move smoothly towards the front end and be discharged, while small-diameter aluminum shot can pass through smoothly for the next round of sorting, thereby improving sorting efficiency and accuracy.

[0027] Please see Figure 1 An inclined guide plate 9 is installed at the front end below the sorting plate 8. The two sides of the guide plate 9 are fixed to the outer shell 1 by screws, and the guide plate 9 extends to the front of the outer shell 1.

[0028] Please see Figure 1 and Figure 4 A dust collection hood 10 is installed on one side of the outer shell 1, and the dust collection hood 10 is connected to the inner cavity of the outer shell 1. A dust collection box 12 is installed on the back of the outer shell 1, and a dust collection pipe 11 is installed between the dust collection box 12 and the dust collection hood 10. A negative pressure fan 21 is installed on one side of the dust collection box 12. During the sorting process, the negative pressure fan 21 is turned on to quickly exhaust the air inside the dust collection box 12. At the same time, the air outside the dust collection hood 10 is continuously replenished into the negative pressure fan 21, forming a high pressure difference with the outside. Then, the dust generated by the vibration and contact of aluminum balls inside the outer shell 1 is sucked into the dust collection box 12 with the air, thereby ensuring the cleanliness of the sorting process.
