Abstract
Description
Technical Field
[0001] This utility model relates to the field of copper powder screening technology, specifically a high-precision copper powder grinding and screening device. Background Technology
[0002] Copper powder is a type of metal powder, mainly made of pure copper or copper alloys. Through specific processes, copper blocks or copper materials are processed into tiny particles. These tiny copper powder particles have a wide range of uses and applications. Their particle size and shape can be adjusted according to different production processes and requirements. Common particle sizes range from a few micrometers to several hundred micrometers.
[0003] High-precision copper powder grinding and screening devices typically refer to mechanical equipment that can accurately and efficiently grind and screen copper powder. These devices generally combine advanced grinding technology and precise screening mechanisms to ensure that the particle size, purity, and quality of the copper powder meet specific requirements. A commonly used vibrating screening device separates copper powder into different particle size grades and has the advantages of high screening efficiency and large processing capacity, making it suitable for large-scale production.
[0004] Existing high-precision copper powder grinding and screening devices often suffer from uneven feeding speeds during the grinding process. This leads to the accumulation or uneven distribution of copper powder on the conveyor belt, resulting in insufficient residence time of the copper powder in the screening area. Consequently, the copper powder cannot be fully subjected to the magnetic field, hindering proper separation and reducing screening efficiency. This makes the devices less user-friendly. Furthermore, the particle size of the copper powder cannot be guaranteed to be within a certain range during the screening process, often resulting in significant particle size differences. This leads to small-diameter particles entering the magnetic discharge hopper, affecting the screening accuracy. Utility Model Content

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0026] The present invention will be further described below with reference to the embodiments.
[0027] Example 1
[0028] Reference Figure 1-4 This is the first embodiment of the present invention, which provides a high-precision copper powder grinding and screening device, including a conveying support frame 1 and a conveying roller belt 2 rotatably installed at the inner center of the conveying support frame 1. The upper end of the conveying support frame 1 is symmetrically equipped with irregularly shaped mounting seats 3. A threaded screw 4 is rotatably installed at the center of one side of the irregularly shaped mounting seat 3. An irregularly shaped sliding seat 5 is rotatably installed on the outer wall of the threaded screw 4. A telescopic spring 6 is fixedly installed at the lower center of the irregularly shaped sliding seat 5. A square mounting block 7 is fixedly installed at the lower end of the telescopic spring 6. Several combing toothed rollers 8 are evenly spaced at the lower end of the square mounting block 7.
[0029] A feeding box 13 is fixedly installed above the screening box 9. A rotating shaft 14 is rotatably installed at the center of the inner side of the feeding box 13. Several grinding rollers 15 are evenly spaced on the outer side wall of the rotating shaft 14. A material distribution partition is movably installed at the lower outlet of the feeding box 13. A magnetic roller 16 is rotatably installed on one side of the conveying support frame 1 near the port of the conveying roller belt 2. A first material distribution plate 17 is fixedly installed in the middle of the two conveying support frames 1 near the upper end of the magnetic roller 16. Suspension rods are symmetrically fixedly installed at the lower ends of both sides of the first material distribution plate 17. A second material distribution plate 18 is fixedly installed in the middle of the two suspension rods.
[0030] A copper powder collection box 19 is fixedly installed at one end of the conveying support frame 1 near the lower end of the first distribution plate 17. A magnetic collection box 20 is fixedly installed at one end of the copper powder collection box 19 near the lower end of the second distribution plate 18. A rotating motor 21 is fixedly installed at the center of one end of the irregular mounting base 3. A threaded screw 4 is connected to the output end of the rotating motor 21. A grinding motor 22 is fixedly installed at the center of one end of the feed box 13. A rotating shaft 14 is connected to the output end of the grinding motor 22.
[0031] When the high-precision copper powder grinding and screening device is in use, the copper powder material is first fed into the inside of the feed box 13, and then the grinding motor 22 is started simultaneously to drive the two rotating shafts 14 to rotate. A rotating gear is meshed and installed on one side of the feed box 13 near the outer wall of the rotating shaft 14, so that the two grinding rollers 15 fixedly installed on the rotating shaft 14 rotate in opposite directions under the drive of the rotating gear to separate and crush the copper powder material. Then, the material falls evenly into the screening box 9 through the material distribution partition set at the lower end of the feed box 13.
[0032] When the copper powder falls onto the conveyor belt 2, the rotating motor 21 is started simultaneously, driving the threaded screw 4 to rotate. This causes the square mounting block 7 to move back and forth to both ends, which in turn causes the combing toothed roller 8, which is close to the conveyor belt 2, to move back and forth to both ends simultaneously. This allows the copper powder accumulated on the conveyor belt 2 to be combed evenly, avoiding the situation where the accumulated material stays in the screening area for too short a time. This prevents the magnetic impurities from being separated from the copper powder when they pass through the magnetic field due to the weak magnetic attraction of the magnetic impurities. This further improves the screening efficiency.
[0033] Among them, a drive motor is fixedly installed at the lower end of the conveyor support frame 1. The drive shaft drives the conveyor belt 2 to rotate, thereby conveying the copper powder material on the conveyor belt 2 to the next screening location. A rotating belt is connected between the drive shaft and the magnetic roller 16, so that the magnetic roller 16 also rotates synchronously when the conveyor belt 2 is conveying.
[0034] When the copper powder is conveyed to the magnetic roller 16 by the conveyor belt 2, the magnetic roller 16 is simultaneously energized, causing the permanent magnet or electromagnet inside the magnetic roller 16 to generate a magnetic field. This magnetic field will exert a repulsive force on the surrounding magnetic copper powder. When the magnetic roller 16 rotates, the non-magnetic components in the copper powder are distributed to the inside of the copper powder collection box 19 by gravity through the first distribution plate 17, while the magnetic components in the copper powder are pushed to the surface of the second distribution plate 18 by the repulsive force of the magnetic force. As the magnetic roller 16 continues to rotate and the alternating arrangement of the magnetic poles causes the magnetic force pushed to the second distribution plate 18 to disappear, the magnetic components in the copper powder will fall into the inside of the magnetic collection box 20 by gravity, thereby realizing the separation and screening process of the ground copper powder.
[0035] Example 2
[0036] Reference Figure 1-4This is the second embodiment of the present utility model. The difference between this embodiment and the first embodiment is that: a screening box 9 is fixedly installed on the side of the two conveying support frames 1 near the irregular mounting seat 3, a screening screen 10 is fixedly installed at the center of the inner side of the screening box 9, an impurity screening channel 11 is opened on the inner side of the screening box 9 near the lower end of the screening screen 10, and an impurity collection box 12 is fixedly installed at the lower end of the impurity screening channel 11.
[0037] After the ground copper powder falls into the screening box 9, the vibration motor installed inside the screening box 9 is started simultaneously. Driven by the vibration motor, the copper powder material falling on the screening screen 10 will cause the small-diameter copper powder material to fall through the impurity screening channel 11 to the inside of the impurity collection box 12, while the copper powder material of the same size will remain on the screening screen 10 and fall onto the conveyor roller belt 2 by vibration and gravity. This avoids the situation where small-diameter material enters the copper powder collection box 19 due to large differences in particle size, and further improves the screening accuracy.
[0038] The remaining structure is the same as that in Example 1.
[0039] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
