Description

Technical Field

[0001] This invention relates to the field of magnesium alloy production technology, and in particular to a structure for recycling magnesium alloy processing debris. Background Technology

[0002] Magnesium alloy sheets need to be processed twice before use, so that the long magnesium alloy sheets can be cut into the specified lengths before they can be used. A lot of debris will be generated during the cutting process.

[0003] In existing technologies, a recycling box is usually placed at the processing outlet to collect the waste shavings after magnesium alloy processing. However, due to the flammable nature of magnesium alloy shavings, when they are poured into the recycling bin, they are prone to friction with the inner wall of the bin and between the magnesium alloy shaving particles, which generates static electricity. Static electricity is extremely easy to cause the shavings to catch fire. Summary of the Invention

[0004] This invention provides a magnesium alloy processing debris recycling structure, which aims to solve the problem that when magnesium alloy debris is poured into the recycling bin, friction easily occurs between the debris and the inner wall of the bin, as well as between the magnesium alloy debris particles, thereby generating static electricity and causing the debris to catch fire.

After the magnesium alloy scraps have been poured out, the conductive rectangular column stops rotating, and at this time the magnesium alloy scraps are stationary and no static electricity is generated.

[0036] This embodiment provides a magnesium alloy machining debris recycling structure, such as... Figure 1 and Figure 10 As shown, a magnesium alloy processing debris recycling structure includes a recycling cylinder 1, a conductive rectangular column 2, a top cover 3, wheels 4, and a rotating assembly 7. It includes an inner cylinder 11 and an outer cylinder 12, with the outer cylinder 12 fitted over the inner cylinder 11. The upper ends of the inner cylinder 11 and outer cylinder 12 are fixedly connected by a first fixing plate 111, and their lower ends are fixedly connected by a fixing assembly 19. A support column 13 is provided at the bottom of the inner cylinder 11, and wheels 4 are provided at the bottom of the outer cylinder 12. The inner cylinder 11 is made of a conductive material, and the outer cylinder 12 is made of a non-conductive material. Figures 6-7As shown, a conductive rectangular post 2 is disposed between the inner cylinder 11 and the outer cylinder 12. A support shaft 21 is fixedly disposed at the bottom of the conductive rectangular post 2, and a rotating arm 22 is connected to the support shaft 21. The end of the rotating arm 22 away from the support shaft 21 is sleeved on the support post 13. A terminal plate 5 is fixedly disposed on the inner side wall of the outer cylinder 12. A circuit assembly 6 is disposed between the rotating arm 22 and the terminal plate 5. The conductive rectangular post 2 is connected to the terminal plate 5 through the support shaft 21, the rotating arm 22, the circuit assembly 6, and to form a conductive path. A rotating assembly 7 is installed on the outside of the support post 13 and is used to drive the rotating arm 22 to rotate circumferentially around the support post 13.

[0037] When magnesium alloy scraps are poured into the inner cylinder 11, the rotating assembly 7 drives the conductive rectangular column 2 to rotate around the outer wall of the inner cylinder 11 via the rotating arm 22. The static electricity generated by the friction of the scraps is transmitted through the side wall of the inner cylinder 11 to the conductive rectangular column 2, and then through the support shaft 21, the rotating arm 22, and the wiring assembly 6 to the terminal plate 5. The terminal plate 5 is grounded, and the current is finally connected to the ground to prevent fire caused by static electricity. After the magnesium alloy scraps have been poured out, the conductive rectangular column 2 stops rotating.

[0038] Specifically, the inner cylinder 11 is made of aluminum alloy, and the outer cylinder 12 is made of rubber.

[0039] like Figures 2-5 As shown, a base plate 14 is fixedly installed at the bottom of the outer cylinder 12. A protruding plate 141 protrudes from one end of the base plate 14, and an installation port 121 is opened on one side of the protruding plate 141 on the outer cylinder 12. An outer shell 15 is installed on the top of the protruding plate 141. An annular cover plate 17 is also provided between the outer cylinder 12 and the inner cylinder 11. The annular cover plate 17 is located on the upper surface of the first fixing plate 111. A handle 171 is provided on the upper surface of the annular cover plate 17 for removing the annular cover plate 17. A top cover 18 is rotatably installed on the top of the outer cylinder 12 and the inner cylinder 11. The fixing assembly 19 includes a fixing ring 191 and a second fixing plate 192. The fixing ring 191 is fixedly installed on the inner side wall of the outer cylinder 12, and the second fixing plate 192 is fixedly installed between the support column 13 and the fixing ring 191. When the magnesium alloy is being poured, the top cover 18 is opened. After the pouring is complete, the top cover 18 is tightened. The annular cover 17 prevents the magnesium alloy from being poured between the inner cylinder 11 and the outer cylinder 12. The fixing component 19 is used to stably connect the outer cylinder 12 and the inner cylinder 11.

[0040] Optionally, such as Figures 6-7 and Figure 12As shown, the circuit assembly 6 includes a first conductor 61, a conductive slip ring 62, and a second conductor 63. The conductive slip ring 62 is sleeved on the outside of the support column 13. The rotating arm 22 includes a connecting rod 221 and a connecting sleeve 222. The connecting rod 221 is fixedly connected to the outer cylinder 621 of the conductive slip ring 62. The connecting sleeve 222 is sleeved on the support column 13. One end of the first conductor 61 is connected to the connecting rod 221, and the other end is connected to the outer cylinder 621 of the conductive slip ring 62. The second conductor 63 is connected to the inner cylinder 622 of the conductive slip ring 62. The second conductor 63 is installed through the inside of the support column 13 and extends from the bottom of the support column 13 to connect with the terminal plate 5. The inner cylinder 622 of the conductive slip ring 62 is fixed relative to the support column 13. The outer cylinder 621 of the conductive slip ring 62 and the rotating arm 22 rotate synchronously relative to the inner cylinder 622 of the conductive slip ring 62. The conductive path is as follows: current is transmitted through the support shaft 21 to the connecting rod 221, then through the first wire 61 to the outer cylinder of the conductive slip ring 62, and then through the second wire 63 to the terminal plate 5, which leads the current to the ground. The support shaft 21, connecting rod 221, and terminal plate 5 are all made of conductive material.

[0041] Optionally, such as Figures 4-7 As shown, the rotating assembly 7 includes: a first pulley 71, a second pulley 72, a rotating column 73, and a driver 74. The first pulley 71 is fixedly connected to the connecting sleeve 222. The rotating column 73 is rotatably mounted on the protruding plate 141 via a connecting block. The second pulley 72 is fixedly connected to the bottom of the rotating column 73. The first pulley 71 and the second pulley 72 are connected by a belt 77. The mounting port 121 is opened to allow the belt 77 to pass through. A first bevel gear 76 is fixedly mounted on the rotating column 73. A second bevel gear 75 meshes with the side of the first bevel gear 76 away from the outer cylinder 12. A driver 74 is fixedly mounted at one end of the second bevel gear 75. The driver 74 is rotatably mounted on the outer casing 15. Figure 13 As shown, a pulley 23 is fixedly mounted on the support shaft 21, and an annular groove 16 is fixedly mounted on the inner cylinder 11. The pulley 23 is slidably disposed within the annular groove 16. Specifically, the driver 74 is most preferably a rocker arm, but it can also be a motor.

[0042] Furthermore, by starting the driver 74, the second bevel gear 75 is driven to rotate, which in turn drives the first bevel gear 76 to rotate, which in turn drives the rotating column 73 to rotate, which in turn drives the second pulley 75 on the rotating column 73 to rotate. At this time, the belt 77 drives the first pulley 71 to rotate, and the first pulley 71 drives the rotating arm 22 to rotate. At this time, the pulley 23 slides in the annular groove 16, thereby causing the conductive rectangular column 2 to rotate along the outer wall of the inner cylinder 11.

[0043] Optionally, such as Figure 8As shown, the conductive rectangular column 2 includes an outer conductor 24 and a central column 25. The central column 25 is fixedly connected to the support shaft 21. The interior of the conductive rectangular column 2 has a vertically oriented mounting groove 241 to accommodate the central column. The four sides of the conductive rectangular column 2 are provided with concave arc shapes that match the outer wall of the inner cylinder 11. Each set of concave arc surfaces is fixed with several conductive bristles 26 that contact the outer wall of the inner cylinder 11. The concave arc surfaces match the shape of the side walls of the inner cylinder 11, and the current is transmitted to the support shaft 21 through the conductive bristles 26. The outer wall of the central column 25 is fixed with multiple sets of positioning ribs 251 in a ring. The side wall of the mounting groove 241 has multiple sets of positioning grooves 252 that cooperate with the positioning ribs 251. When the conductivity of the conductive bristles 26 on one side decreases after prolonged use, the outer conductor 24 can be pulled out from the outside of the central post 25, rotated 90°, and then the outer conductor 24 can be re-sleeved onto the central post 25. The cooperation between the positioning ribs 251 and the positioning grooves 252 ensures that the outer conductor 24 and the central post 25 will not rotate arbitrarily and will remain in a relatively fixed state.

[0044] Optionally, such as Figure 9 and Figure 13 As shown, the upper surface of the conductive rectangular post 2 has four sets of slots 27 equidistantly arranged in a ring. The top of the conductive rectangular post 2 is connected to the top of the central post 25 through a cross connector 29. The center of the upper surface of the central post 25 has a disc groove 28. The cross connector 29 includes a disc 291 and four sets of L-shaped inserts 292. The four sets of L-shaped inserts 292 are fixedly arranged in a ring at equal intervals around the disc 291. The end of the L-shaped insert 292 away from the disc 291 is fixedly inserted into the corresponding slot 27. The disc 291 is fixedly connected to the disc groove 28 by screws to form a conductive path. The current is transmitted from the conductive bristles 26 through the L-shaped inserts 292 to the disc 291, and then to the central post 25. The central post 25 transmits the current to the support shaft 21, avoiding the decrease in conductivity due to the gap between the central post 25 and the outer conductor 24. When the conductivity of the conductive bristles 26 on one side decreases after prolonged use, the outer conductor 24 can be pulled out from the outside of the central post 25, rotated 90°, and then the outer conductor 24 can be re-sleeved onto the central post 25. The cooperation between the positioning ribs 251 and the positioning grooves 252 ensures that the outer conductor 24 and the central post 25 will not rotate arbitrarily and will remain in a relatively fixed state.

[0045] The working principle of this invention is as follows: When magnesium alloy scrap needs to be recycled, the top cover 18 is opened, and magnesium alloy scrap is poured into the inner cylinder 11. By starting the driver 74, the second bevel gear 75 is rotated, which in turn drives the first bevel gear 76 to rotate, which in turn drives the rotating column 73 to rotate, which in turn drives the second pulley 72 on the rotating column 73 to rotate. At this time, the belt 77 drives the first pulley 71 to rotate, and the first pulley 71 drives the rotating arm 22 to rotate. At this time, the pulley 23 slides in the annular groove 16, so that the conductive rectangular column 2 rotates along the outer wall of the inner cylinder 11. The static electricity generated by the friction of the scrap is transmitted to the conductive rectangular column 2 through the side wall of the inner cylinder 11. In the rectangular column 2, current is transmitted from the conductive bristles 26 through the L-shaped insert plate 292 to the disk 291, and then to the central column 25. The central column 25 transmits the current to the support shaft 21. The cross-shaped connecting bracket 29 prevents reduced conductivity due to gaps between the central column 25 and the outer conductor 24. The current is then transmitted through the support shaft 21 to the connecting rod 221, and then through the first wire 61 to the outer cylinder 621 of the conductive slip ring 62. Finally, it is transmitted through the second wire 63 to the terminal plate 5, which leads the current to the ground. This prevents static electricity from being generated between the magnesium alloy debris and the inner cylinder 11, or between the magnesium alloy debris particles themselves, which could lead to a fire. After the magnesium alloy debris has been completely dumped, the conductive rectangular column 2 stops rotating, and the magnesium alloy debris is stationary, preventing the generation of static electricity.
