[0016] The following is in conjunction with the appendix Figure 1 —9. The present invention will be described in further detail.

[0017] This invention discloses a copper powder separation device for valve core processing, comprising a base 1, a separation frame 2 rotatably mounted on the top of the base 1, a plurality of screening screens 3 installed in the through slots at both ends of the separation frame 2, and fixing holes 20 at both ends of the screening screens 3, corresponding to the positions of the slots 21 at both ends of the separation frame 2, a feed pipe 4 installed at one end of the separation frame 2, the feed pipe 4 being fixed on a support frame provided on the base 1, a discharge pipe 5 installed at the other end of the separation frame 2, an automatic replacement mechanism for replacing the screening screens 3 on the separation frame 2 installed on one side of the base 1, the automatic replacement mechanism being provided with an automatic flipping component, a fixing structure for limiting the separation frame 2 installed at one end of the base 1, a cleaning mechanism for cleaning the screening screens 3 on the separation frame 2 installed on the other side of the base 1, and a dispersing mechanism installed on the feed pipe 4; refer to Figure 1 , Figure 2 , Figure 3 and Figure 4The automatic replacement mechanism includes a mounting frame 6 fixedly installed on one side of the base 1. A first motor 7 is fixedly installed at one end of the mounting frame 6. The output end of the first motor 7 passes through the mounting frame 6 and is connected to one end of a lead screw 8 installed inside. The other end of the lead screw 8 is connected to a bearing seat provided on the inner wall of one end of the mounting frame 6. A movable seat 9 is also adapted to be installed on the lead screw 8. An L-shaped support plate 10 is installed on the top of the movable seat 9. A fixed plate 11 is installed at one end of the L-shaped support plate 10. A first electric telescopic rod 12 and a second electric telescopic rod 13 are fixedly installed on one side of the fixed plate 11. The automatic flipping assembly includes the mounting frame 6... An extension base 14 is fixedly installed at one end of frame 6. A second motor 15 is fixedly installed on the extension base 14. The output end of the second motor 15 passes through a shaft hole at one end of the extension base 14 and is connected to one end of the first drive shaft 16. A rotating frame 17 is fixedly installed at the other end of the first drive shaft 16. Mounting plates 18 are connected to both ends of the rotating frame 17. A placement frame 19 is fixedly installed on the mounting plate 18. A replacement screening screen plate 3 is installed in the placement groove on the placement frame 19. The placement groove on the placement frame 19 corresponds to the through grooves at both ends of the separation frame 2. More specifically, when the screening screen on the separation frame 2... When one or more screen plates 3 are damaged and need to be replaced, the first motor 7 drives the lead screw 8 to rotate, causing the movable seat 9 to slide along the mounting frame 6, so that the L-shaped support plate 10 moves to the corresponding position. Then, one end of the first electric telescopic rod 12 is inserted into the fixing hole 20 at one end of the old screening screen plate 3, and one end of the second electric telescopic rod 13 is inserted into the fixing hole 20 at the other end of the new screening screen plate 3. Then, the first motor 7 is driven to make the movable seat 9 move in the opposite direction, smoothly pulling the old screening screen plate 3 out of the through groove of the separation frame 2, while simultaneously moving the new screening screen plate 3 out of the placement groove of the placement frame 19. When the old screening screen plate After completely detaching from the separation frame, the new screening screen plate 3 is inserted into the through groove of the separation frame 2, thus completing the replacement of one of the screening screen plates 3 on the separation frame 2. At this time, the second motor 15 starts, driving the first drive shaft 16 to rotate, causing the rotating frame 17, together with the mounting plate 18 and the placement frame 19, to rotate 180 degrees synchronously, aligning the next set of new screening screen plates 3 with the through groove position of the separation frame 2, preparing for subsequent continuous replacement operations. This allows for the rapid and efficient replacement of one or more screening screen plates 3 on the separation frame 2, effectively improving replacement efficiency and reducing equipment downtime, ensuring production continuity.

[0018] refer to Figure 5The fixing mechanism includes a first L-shaped support frame 22 installed at one end of the base 1 near the edge of the discharge pipe 5 of the separation frame 2. An electric cylinder 23 is fixedly installed at the other end of the first L-shaped support frame 22. The output end of the electric cylinder 23 passes through the through hole opened on the first L-shaped support frame 22 and is connected to a limiting flange 24. One end of the limiting flange 24 is adapted to the limiting holes 25 opened at the corners of both ends of the separation frame 2. More specifically, when the separation frame 2 is moved to the designated position for the replacement of the screening screen 3, the electric cylinder 23 on the first L-shaped support frame 22 is activated, pushing the limiting flange 24 into the limiting hole 25 at the corner of the separation frame 2, thereby achieving precise positioning and fixing of the separation frame 2. This effectively prevents positional displacement caused by vibration or external force during the replacement process and ensures the centering and smoothness of the new and old screening screen 3 during the pull-out replacement.

[0019] refer to Figure 6 , Figure 7 and Figure 8 The cleaning mechanism includes two symmetrical second L-shaped support frames 26 fixedly installed on the other side of the base 1. A cleaning brush roller 28 is rotatably mounted in a shaft hole near the bottom of the side wall of each of the two second L-shaped support frames 26. One end of the cleaning brush roller 28 passes through a shaft hole in the side wall of one of the second L-shaped support frames 26 and is connected to a first drive motor 27 fixedly installed on the other side wall of the second L-shaped support frame 26. The other end of the cleaning brush roller 28 passes through a shaft hole in the side wall of the other second L-shaped support frame 26 and is fitted with a first transmission wheel 29. A transmission assembly is also installed on the side wall of the other second L-shaped support frame 26. The transmission assembly includes a second transmission shaft 31 installed in a shaft hole in the side wall of the second L-shaped support frame 26. A second transmission wheel 32 is mounted on one end of the second transmission shaft 31. A transmission belt 30 is fitted onto the second transmission wheel 32 and the first transmission wheel 29. A rotating block 33 is also fixedly installed on the second transmission shaft 31 on one side of the second transmission wheel 32. The outer wall of the rotating block 33 is fitted with... A lever 34 is provided, and a vibration assembly is installed between the other ends of the two second L-shaped support frames 26. The vibration assembly includes a rotating rod 35 installed between the shaft holes opened at the other end of the second L-shaped support frame 26. Several striking rods 36 are installed on the rotating rod 35, and a rotating disk 37 is also installed at one end of the rotating rod 35. More specifically, when cleaning the screening screen plate 3, the first drive motor 27 starts, driving the cleaning brush roller 28 to rotate. At the same time, the power is transmitted to the second drive wheel 32 through the first transmission wheel 29 and the transmission belt 30, which in turn drives the second transmission shaft 31 to rotate. This causes the rotating block 33 to drive the lever 34 to rotate, so that the lever 34 periodically moves the rotating disk 37, causing the rotating rod 35 to swing back and forth. This causes the several striking rods 36 installed on it to strike the screening screen plate 3, effectively removing material residue that clogs the mesh. At the same time, the rotating cleaning brush roller 28 simultaneously brushes the surface of the screening screen plate 3, achieving double cleaning of the screening screen plate 3 and effectively improving cleaning efficiency and thoroughness.

[0020] refer to Figure 9 The dispersing mechanism includes a first dispersing roller 38 and a second dispersing roller 39 installed at the bottom of the feed inlet of the feed pipe 4. One end of the first dispersing roller 38 passes through a through hole in the side wall of the feed pipe 4 and is connected to a second drive motor 40 fixedly installed in the side wall of the feed pipe 4. The other end of the first dispersing roller 38 and the second dispersing roller 39 passes through a through hole in the other side wall of the feed pipe 4 and is equipped with a first gear 41 and a second gear 42. The first gear 41 and the second gear 42 mesh with each other. More specifically, when the material enters from the feed inlet, the second drive motor 40 starts and drives the first dispersing roller 38 to rotate. Through the meshing transmission of the first gear 41 and the second gear 42, the second dispersing roller 39 rotates synchronously in the opposite direction. The first dispersing roller 38 and the second dispersing roller 39 effectively disperse the material, preventing it from accumulating and clogging on the screening screen plate 3, ensuring that the material is evenly dispersed and falls smoothly into the screening area, thereby improving screening efficiency and processing capacity.

[0021] The implementation principle of a copper powder separation device for valve core processing according to an embodiment of the present invention is as follows: When separating copper powder, the material is placed into the feed pipe 4, and the second drive motor 40 operates, causing the first dispersing roller 38 and the second dispersing roller 39 to rotate in opposite directions, fully dispersing the material and ensuring that the material is evenly dispersed and falls smoothly into the separation frame 2. The separation frame 2 rotates under the drive of the motor to separate the material. At the same time, the first drive motor 27 starts, driving the cleaning brush roller 28 to rotate and brush the surface of the screening screen plate 3. Simultaneously, the power is transmitted to the second drive roller 32 through the first transmission wheel 29 and the transmission belt 30, thereby driving the second transmission shaft 3. 1. Rotation causes the rotating block 33 to drive the lever 34 to rotate, which in turn causes the lever 34 to periodically actuate the rotating disk 37, causing the rotating rod 35 to swing back and forth. This causes several striking rods 36 mounted on the rod to strike the screening screen plate 3, effectively removing material residue that clogs the mesh. This ensures that the screening screen plate 3 remains unobstructed during dynamic screening. After being dispersed, the material is evenly distributed on the screening screen plate 3. Fine copper powder particles pass through the mesh and fall into the lower collection device, while coarse particles move along the mesh surface to the discharge pipe for discharge, completing the grading and separation. When one or more screening screen plates 3 on the separation frame 2 are damaged and need to be replaced, the electric cylinder 23 on the first L-shaped support frame 22 is activated, pushing the limit switch. Flange 24 is inserted into the limiting hole 25 at the corner of the separation frame 2 to achieve precise positioning and fixation of the separation frame 2. Then, the first motor 7 drives the lead screw 8 to rotate, causing the moving seat 9 to slide along the mounting frame 6, so that the L-shaped support plate 10 moves to the corresponding position. Then, one end of the first electric telescopic rod 12 is driven to insert into the fixing hole 20 at one end of the old screening screen plate 3, and one end of the second electric telescopic rod 13 is driven to insert into the fixing hole 20 at the other end of the new screening screen plate 3. Then, the first motor 7 is driven to move the moving seat 9 in the opposite direction, so as to smoothly pull the old screening screen plate 3 out of the through groove of the separation frame 2, while simultaneously moving the new screening screen plate 3 out of the placement frame 19. When the old screening screen plate 3 is completely detached from the separation frame 2, the new screening screen plate 3 is inserted into the through slot of the separation frame 2, thus completing the replacement of one of the screening screen plates 3 on the separation frame 2. At this time, the second motor 15 starts, driving the first drive shaft 16 to rotate, so that the rotating frame 17, together with the mounting plate 18 and the placement frame 19, rotate 180 degrees synchronously, aligning the next set of screening screen plates 3 to be replaced with the through slot position of the separation frame 2, preparing for subsequent continuous replacement operations. This allows for the quick and efficient replacement of one or more screening screen plates 3 on the separation frame 2, effectively improving replacement efficiency and reducing equipment downtime, ensuring production continuity.

[0022] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
