[0002] Aluminum sheet is a common metal material used in various fields. It is a rectangular sheet formed by rolling aluminum ingots. Depending on the alloy composition, aluminum sheet can be divided into pure aluminum sheet, alloy aluminum sheet, thin aluminum sheet, medium-thick aluminum sheet, and patterned aluminum sheet. In the current aluminum sheet processing industry, grinding and polishing are crucial processes, improving the surface quality of aluminum sheet and meeting the requirements of high precision and aesthetics.

[0003] The plate grinding and polishing equipment in the prior art, such as a quartz stone plate processing grinding and polishing equipment disclosed in the Chinese patent application document with publication number CN117161868A, can perform double grinding on the plate surface through the arrangement of high-mesh grinding discs, low-mesh grinding discs, linear drive elements, telescopic columns and bidirectional telescopic rods, thereby achieving better grinding and polishing effects. There is no need for staff to replace high-mesh grinding discs and low-mesh grinding discs during processing, which is more convenient, fast and efficient.

[0004] However, during the operation of the above-mentioned plate processing grinding and polishing equipment in the prior art, the debris and particles generated by the plate may be blocked between the abrasive grains of the grinding sheet, affecting the grinding effect, or the grinding sheet may gradually wear out during use and lose its grinding ability. In these cases, the grinding sheet needs to be replaced, and the replacement of the grinding sheet requires shutdown, which is time-consuming and labor-intensive, which will cause the production process to be interrupted and affect production efficiency. Summary of the Invention

[0039] Specific embodiments of the aluminum plate grinding device provided by the present invention: like Figures 1-9 As shown, the present invention provides an aluminum plate polishing device, comprising a workbench 1, a suspension 2, a fixed frame 3, a rotating frame 4, a polishing mechanism 5, a discharge barrel 6, a loading barrel 7, and an alignment rod 8. The suspension 2 is mounted above the workbench 1, the fixed frame 3 is slidably mounted on the suspension 2, the rotating frame 4 is suspended on the fixed frame 3 and rotates around its own axis, the polishing mechanism 5 is rotatably mounted on the fixed frame 3, the discharge barrel 6 and the loading barrel 7 are located on the inner and outer sides of the polishing mechanism 5, respectively, and the alignment rod 8 is movably mounted on the rotating frame 4.

[0040] like Figure 1 As shown, the workbench 1 includes a work frame 11 and a conveyor belt 12. The conveyor belt 12 rotates back and forth on the work frame 11. The upper surface of the conveyor belt 12 is used to place the plate 100, driving the plate 100 back and forth. This allows the plate 100 to be polished along its length, increasing the polishing area and improving processing efficiency. Furthermore, automated conveying maintains a constant feed rate, significantly improving polishing quality compared to manual operation.

[0041] like Figure 1 、 Figure 2 and Figure 10 As shown, the suspension 2 includes a support frame 21 and a rectangular frame 22. The support frame 21 is located on the left and right sides of the workbench 1, and the rectangular frame 22 is arranged across the top of the workbench 1. The ends of the rectangular frame 22 are fixedly mounted on the support frame 21. The fixed frame 3 is slidably mounted in the rectangular frame 22. The fixed frame 3 includes a fixed seat 31 and a base plate 32. The base plate 32 is an annular plate, which is integrally formed at the bottom of the fixed seat 31 or can be removably fixed to the bottom of the fixed seat 31. The fixed frame 3 is slidably mounted in the rectangular frame 22 via the fixed seat 31. The rectangular frame 22 is provided with a plurality of grooves extending left and right. The fixed seat 31 is provided with a protrusion 311 that slides into each groove. The fixed frame 3 moves left and right along the grooves via the protrusion 311, thereby moving the rotating frame 4 and the polishing mechanism 5 left and right. The plate 100 placed on the workbench 1 is polished in the width direction, thereby increasing the polishing area and improving the processing efficiency.

[0042] like Figure 2 、 Figure 9 and Figure 11 As shown, the rotating frame 4 includes an upper ring frame 41, a lower ring frame 42 and a connecting plate 43. The upper ring frame 41 and the lower ring frame 42 are fixedly connected by the connecting plate 43. The rotating frame 4 is suspended on the bottom plate 32 of the fixed frame 3 through the upper ring frame 41 and can rotate around its own axis on the bottom plate 32.

[0043] like Figure 2-Figure 6As shown, the polishing mechanism 5 includes a first motor 51, a spindle 52, a first plate 53, a second plate 54, polishing elements 55, and a lifting element 56. The first motor 51 is mounted on a fixed base 31. The spindle 52 passes through the fixed base 31 and is mounted on the first motor 51. The first motor 51 drives the spindle 52 to rotate about its own axis. The first plate 53 and the second plate 54 are fixedly mounted on the spindle 52 with a spacing therebetween. The first plate 53 is rotatably mounted within the base 32, while the second plate 54 is fixedly mounted at the lower end of the spindle 52. Multiple polishing elements 55 and a lifting element 56 are positioned between the first and second plates 53, 54. The polishing elements 55 are spaced apart and arranged around the spindle 52. The lifting element 56 controls the vertical movement of the polishing elements 55. The first motor 51 drives the spindle 52 to rotate, which in turn drives the first and second plates 53, 54 to rotate. This causes all polishing elements 55 mounted between the first and second plates 53, 54 to rotate about the spindle 52, thereby polishing the plate 100. In this embodiment, four polishing members 55 and four lifting members 56 are provided and evenly distributed between the first plate 53 and the second plate 54 .

[0044] like Figure 5 、 Figure 6 and Figure 12 As shown, the polishing member 55 includes a housing 551, a second motor 552, a main rod 553, a polishing plate 554, and a limiting plate 555. The second motor 552 is installed in the housing 551, the main rod 553 passes through the bottom of the housing 551 and is installed on the second motor 552. The limiting plate 555 is fixedly mounted on the main rod 553, and the polishing plate 554 is clamped to the lower end of the main rod 553 for easy disassembly and installation. The second plate 54 is provided with holes for the limiting plate 555 and the polishing plate 554 to pass through, so as to limit the radial direction of the main rod 553 and prevent the main rod 553 from shaking during rotation, thereby ensuring the polishing effect of the polishing plate 554 on the plate 100. The main rod 553 is driven to rotate by the second motor 552, which in turn drives the polishing plate 554 to rotate and polish the plate 100.

[0045] like Figure 4-Figure 6As shown, the lifting member 56 includes a third motor 561, an active rod 562, a driven rod 563, and a gear ring 564. The third motor 561 is mounted on the first plate 53 via an L-shaped mounting plate. Specifically, the L-shaped mounting plate includes a vertical plate fixed to the upper surface of the first plate 53 and a horizontal plate fixed to the top of the vertical plate. The third motor 561 is fixedly mounted on the horizontal plate. In the vertical direction, the third motor 561 and the first plate 53 are spaced apart from each other to form a neutral position. The upper end of the active rod 562 passes through the first plate 53 and is connected to the third motor 561. The lower end of the active rod 562 is rotatably mounted on the second plate 54. The upper and lower ends of the driven rod 563 are rotatably mounted on the first and second plates 53, respectively. Gear rings 564 are rotatably mounted on the upper and lower surfaces of the first plate 53, respectively. The upper ends of the active rod 562 and the driven rod 563 are respectively equipped with first gears 565 that mesh with the gear rings 564.

[0046] Specifically, the box body 551 is slidably assembled on the active rod 562 and the driven rod 563. The outer surfaces of the active rod 562 and the driven rod 563 are respectively provided with spiral grooves. The box body 551 is provided with a circular hole for the active rod 562 and the driven rod 563 to pass through, and a guide block is provided in the circular hole to slide with the spiral groove.

[0047] In this embodiment, there are two third motors 561, and an active rod 562 corresponds to each third motor 561. That is, there are two active rods 562 and six driven rods 563. Two driven rods 563, or one active rod 562 and one driven rod 563, form a group, for a total of four groups, each corresponding to a polishing member 55.

[0048] One of the third motors 561 corresponds to the gear ring 564 on the upper surface of the first plate 53, and controls the rotation of the active rod 562 and the driven rod 563 in the two rod groups arranged opposite to each other. The first gear 565 assembled on the upper ends of the active rod 562 and the driven rod 563 in the two rod groups is located on the upper surface of the first plate 53 and is respectively engaged with the gear ring 564 on the upper surface of the first plate 53; wherein, the first gear 565 on the active rod 562 is located in the gap between the third motor 561 and the first plate 53.

[0049] Another third motor 561 corresponds to the gear ring 564 on the lower surface of the first plate 53, and controls the rotation of the active rod 562 and the driven rod 563 in the other two rod groups arranged opposite to each other. The first gear 565 assembled at the upper ends of the active rod 562 and the driven rod 563 in the two rod groups is located on the lower surface of the first plate 53 and is respectively engaged with the gear ring 564 on the lower surface of the first plate 53.

[0050] By starting the third motor 561 to drive the active rod 562 to rotate, and then driving the gear ring 564 to rotate through the first gear 565 installed on the active rod 562, and then driving the first gear 565 on the driven rod 563 to rotate through the gear ring 564, the active rod 562 and the driven rod 563 rotate in the circular hole of the box body 551, and the guide block in the circular hole slides along the spiral groove, driving the box body 551 to move up and down, so as to realize the up and down movement of the polishing part 55.

[0051] The four polishing members 55 are divided into two groups, each group including two polishing members 55 arranged opposite to each other. By starting the third motor 561, one group of polishing members 55 can be controlled to move up and down to replace the polishing plate 554 on the polishing member 55 in this group, while the other group of polishing members 55 can continue to work without stopping, thereby ensuring the continuity of the production process and significantly improving production efficiency.

[0052] like Figure 5 、 Figure 6 、 Figure 8 and Figure 12 As shown, each polishing member 55 is provided with a discharge barrel 6 and a discharge claw 61 on its inner side. The discharge claw 61 is mounted on the discharge barrel 6 via an elastic member 62, while the discharge barrel 6 is mounted on the spindle 52 on its side close to the spindle 52 via a spring 63. A slider 64 is provided at the lower end of the discharge barrel 6, and a slide groove 541 is provided on the second plate 54 for the slider 64 to slide. A baffle 5511 is provided on the side of each box 551 close to the spindle 52 to cooperate with the discharge barrel 6 to limit the sliding of the discharge barrel 6. When it is necessary to replace the polishing plate 554 of one group of polishing parts 55, the third motor 561 controls the upward movement of the group of polishing parts 55 through the active rod 562 and the driven rod 563, and at the same time, the baffle 5511 of the box body 551 moves upward. When the baffle 5511 is out of contact with the discharge barrel 6, the discharge barrel 6 moves outward to the bottom of the polishing plate 554 under the elastic force of the spring 63, and is aligned with the polishing plate 554 up and down. At the same time, the discharge claw 61 located above the discharge barrel 6 extends between the polishing plate 554 and the limit plate 555, and the lifting member 56 continues to control the upward movement of the box body 551. The elastic member 62 gives the discharge claw 61 a downward elastic force, so that the polishing plate 554 is separated from the main rod 553 and falls into the discharge barrel 6 directly below, completing the removal of the damaged polishing plate 554.

[0053] In this embodiment, the end of the discharge claw 61 near the housing 551 is angled to facilitate insertion between the polishing plate 554 and the stop plate 555. The lower end of the baffle 5511 is provided with an inclined surface to facilitate insertion of the baffle 5511 into the exterior of the discharge barrel 6. The cavity of the discharge barrel 6 is a tapered cavity, larger at the top and smaller at the bottom, making it easy to remove any polishing plate 554 that has fallen into the discharge barrel 6.

[0054] like Figure 4 、 Figure 5 、 Figure 6 and Figure 9 As shown, a loading barrel 7 is provided outside each polishing element 55 and mounted on the lower ring frame 42. An opening 71 is formed at the lower end of the side wall of the loading barrel 7, extending through the barrel and facing the main rod 553. A pusher plate 72 is slidably mounted within the opening 71. The lower ring frame 42 is also provided with a driving member for driving the pusher plate 72 to move within the opening 71 toward or away from the main rod 553. Specifically, a new polishing plate 554 is loaded in the loading barrel 7, and the polishing plate 554 falls onto the pushing plate 72 through the loading barrel 7, and the driving member drives the pushing plate 72 to move toward the main rod 553, and the pushing plate 72 pushes the new polishing plate 554 toward the main shaft 52 until the new polishing plate 554 is directly below the main rod 553, and the third motor 561 drives the polishing member 55 to move downward through the active rod 562 and the driven rod 563 until the lower end of the main rod 553 is clamped and fixed with the new polishing plate 554, and the third motor 561 drives the polishing member 55 to move upward through the active rod 562 and the driven rod 563, and the driving member drives the pushing plate 72 to return, completing the assembly of the new polishing plate 554, and the assembly process does not affect the normal operation of another group of polishing members 55, thereby ensuring the normal progress of the polishing process.

[0055] like Figure 6 、 Figure 7 and Figure 9 As shown, the drive assembly includes a ring gear 731, a second gear 732, and a fourth motor 733. The ring gear 731 is mounted on the outer circumference of the lower ring frame 42. The fourth motor 733 is mounted on the lower ring frame 42 to drive the ring gear 731 to rotate about the central axis of the lower ring frame 42. The lower ring frame 42 has a notch 421 for the rotatable mounting of the second gear 732. The second gear 732 meshes with the ring gear 731. The pusher plate 72 is also provided with a rack 721 that meshes with the second gear 732. By activating the fourth motor 733, the ring gear 731 rotates about the central axis of the lower ring frame 42. The ring gear 731 rotates the second gear 732, which in turn drives the rack 721 toward or away from the central axis of the lower ring frame 42. This, in turn, drives the pusher plate 72 via the rack 721, allowing the pusher plate 72 to move directly below the main rod 553 for the installation of a new polishing plate 554.

[0056] The outer wall of the lower ring frame 42 is provided with two symmetrically arranged mounting openings 422. An alignment rod 8 is mounted within these openings, allowing it to move toward or away from the central axis of the lower ring frame 42. The alignment rod 8 is equipped with a tension spring 81 and a stopper 82. The outer wall of the second plate 54 is provided with locking holes 542 corresponding to the alignment rods 8. The end of the alignment rod 8, away from the central axis of the lower ring frame 42, has a wedge-shaped surface. When the fourth motor 733 drives the ring gear 731 to rotate around the central axis of the lower ring frame 42, the ring gear 731 can push the wedge surface of the alignment rod 8 to move the alignment rod 8 toward the central axis of the lower ring frame 42 until the alignment rod 8 is inserted into the locking hole 542 on the outer peripheral wall of the second plate 54. At this time, the push plate 72 and the main rod 553 that needs to be assembled with the new polishing plate 554 are aligned in the radial direction of the lower ring frame 42, and the rotating frame 4 can rotate together with the second plate 54 to ensure that when the push plate 72 moves toward the central axis of the lower ring frame 42, the new polishing plate 554 can be pushed to the bottom of the main rod 553, thereby ensuring that the polishing plate 554 can be smoothly replaced without stopping the machine.

[0057] like Figure 6 and Figure 13 As shown, the inner wall of the ring gear 731 is provided with gear teeth segments 731a and empty tooth segments 731b, which are alternately arranged along the circumference of the ring gear 731. When the polishing plates 554 of one set of polishing elements 55 need to be replaced, the fourth motor 733 drives the ring gear 731 to rotate until the gear teeth segments 731a mesh with two of the oppositely disposed second gears 732, thereby controlling the movement of the two oppositely disposed pusher plates 72 to assemble the new polishing plate 554 onto the set of polishing elements 55. At this time, the empty tooth segments 731b are located between the other two oppositely disposed second gears 732, thereby preventing the other two oppositely disposed pusher plates 72 from affecting the normal operation of the other set of polishing elements 55.

[0058] According to the above description of this specification, those skilled in the art may also understand that the terms used below, such as "up", "down", "front", "back", "left", "right", "width", "horizontal", "top", "bottom", "inside", "outside" and other terms indicating orientation or positional relationships are based on the orientation or positional relationships shown in the drawings of this specification. They are only for the purpose of facilitating the explanation of the scheme of the present invention and simplifying the description, rather than explicitly or implicitly indicating that the devices or elements involved must have the specific orientation, be constructed and operated in a specific orientation. Therefore, the above-mentioned orientation or positional relationship terms cannot be understood or interpreted as limitations on the scheme of the present invention.

[0059] In addition, in the description of this specification, “a plurality of” means at least two, for example, two, three or more, etc., unless otherwise clearly and specifically defined.
