[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] This invention provides a positioning surface processing device for the renovation of building aluminum panels, including a box body 1 and a positioning mechanism 3. One end of the top of the box body 1 is provided with an adjusting mechanism 2 that can adjust the direction of the positioning mechanism 3. Above the adjusting mechanism 2 is a positioning mechanism 3 that can press and position the aluminum panel. The middle of the inner cavity of the box body 1 is provided with a cutting mechanism 5. The bottom of the box body 1 is provided with a moving mechanism 4. The inner side wall of the box body 1 is provided with a cleaning mechanism 6. The end of the moving mechanism 4 is provided with a collecting mechanism 7. The positioning mechanism 3 includes a connecting beam 31, which is located above the adjusting mechanism 2.

[0037] Both sides of the connecting beam 31 are fixedly installed with reinforcing side plates 32. The top of the connecting beam 31 is fixedly installed with a second electric push rod 33. The output shaft of the second electric push rod 33 is fixedly installed with a pressure frame 34. Both ends of the top of the pressure frame 34 are fixedly installed with vertical rods 35. The top of the vertical rods 35 extends through to the top of the connecting beam 31. The vertical rods 35 and the connecting beam 31 are slidably connected. The bottom and one end of the pressure frame 34 are open.

[0038] The second electric push rod 33 can push the pressure frame 34 to achieve the positioning and clamping of the aluminum plate during the refurbishment and cutting process.

[0039] Preferably, the steering mechanism 2 includes a pushing component, a supporting component, and a displacement component. The supporting component is located at one end of the top of the housing 1, the pushing component is located below the inner side of the supporting component, and the displacement component is located on the outer side of the supporting component.

[0040] like Figure 3 As shown, the support assembly includes a drive shaft 21 and a gear 22. The drive shaft 21 is rotatably mounted on one end of the top of the housing 1, and the gear 22 is fixedly mounted on the outer end of the drive shaft 21, which facilitates transmission and auxiliary support.

[0041] like Figure 3 As shown, the pushing assembly includes a first electric push rod 25 and a connecting frame 24. The first electric push rod 25 is fixedly installed at one end of the top of the housing 1, and the connecting frame 24 is fixedly installed at the output end of the first electric push rod 25, which can push the force of rotation during adjustment.

[0042] like Figure 3As shown, the displacement assembly includes a toothed plate 23 and a connecting rod 26. The connecting rod 26 is fixedly installed on both sides of the top of the housing 1. The bottom of the toothed plate 23 is provided with an adapter groove. The toothed plate 23 is slidably connected to the connecting rod 26 through the adapter groove. The gear 22 and the toothed plate 23 mesh, and the position of the pressure frame 34 can be adjusted by rotation through meshing, so as to facilitate the material loading and unloading operation.

[0043] When refurbishing and cutting aluminum plates, the pressing and positioning of the aluminum plates can be completed in the state shown in the figure.

[0044] When adjustments are needed:

[0045] The first electric push rod 25 drives the connecting frame 24 to pull back, and the connecting frame 24 drives the two sets of toothed plates 23 to move back together. At this time, the toothed plates 23 will slide horizontally on the top of the connecting rod 26, and at the same time, the toothed plates 23 and the gear 22 will mesh, causing the gear 22 to rotate. When the gear 22 rotates, it will drive the transmission shaft 21 to rotate together. Since the connecting beam 31 and the transmission shaft 21 are fixedly installed, when the transmission shaft 21 rotates, it will drive the connecting beam 31 to rotate together. The components connected to the connecting beam 31 will also be driven to rotate, thereby completing the rotation adjustment operation and rotating the pressure frame 34 to be above the gear 22.

[0046] When adjusting upward rotation, the second electric push rod 33 needs to be pulled back by the pressure frame 34 beforehand until the bottom of the pressure frame 34 and the connecting beam 31 are in a fitted state.

[0047] At this point, the aluminum plates can be picked up and placed. After picking up and placing, positioning and clamping work should be carried out.

[0048] When it is necessary to press and fix, the above operation can be reversed. That is, the first electric push rod 25 will push the connecting frame 24 to move the toothed plate 23. The meshing connection will cause the connecting beam 31 to move the pressure frame 34 to the state shown in the figure. Then the second electric push rod 33 will push the pressure frame 34 to move downward until it contacts the aluminum plate and press it down to fix it.

[0049] The bottom and one end of the pressure frame 34 are open, which facilitates the movement and cutting of the blade assembly 54, and also makes it easy to shield aluminum dust during cutting to prevent dust leakage.

[0050] like Figure 5 and 7As shown, the moving mechanism 4 includes a first motor 41, which is fixedly installed at one end of the housing 1. The output shaft of the first motor 41 is keyed to a rotating rod 42. Both ends of the rotating rod 42 are fixedly installed with moving wheels 43. One end of the rotating rod 42 is rotatably connected to the inner wall of the housing 1. The bottom of the moving wheel 43 is rolledly connected to a track 44, and a base plate 45 is fixedly installed at the bottom of the track 44.

[0051] The first motor 41 drives the operation, while the rotating rod 42 and the moving wheel 43 provide auxiliary support and rolling movement. The track 44 and the base plate 45 support the box 1 while the moving wheel 43 and the track 44 roll together to facilitate operation.

[0052] When moving:

[0053] The first motor 41 is directly activated, and the first motor 41 drives the rotating rod 42 to rotate, causing the moving wheel 43 to rotate. The moving wheel 43 then rolls on the top of the track 44, thereby driving the box 1 and its internal and external components to move horizontally to the required position. The required position can be adjusted to support and cut aluminum plates of different lengths.

[0054] like Figure 8 As shown, the cutting mechanism 5 includes a third electric push rod 51, which is fixedly installed through the middle of one end of the housing 1. A bracket 52 is fixedly installed at the output end of the third electric push rod 51. A blade assembly 54 is rotatably connected inside the bracket 52. A second motor 53 is bolted to one side of the bracket 52. The output shaft of the second motor 53 is keyed to one end of the blade assembly 54. A sliding sleeve 55 is fixedly installed on the outside of the bracket 52. A crossbar 56 is fixedly installed on both sides of the inner cavity of the housing 1. The sliding sleeve 55 is slidably connected to the surface of the crossbar 56.

[0055] It facilitates horizontal movement for cutting aluminum plates, aluminum profiles, and aluminum rods;

[0056] During cutting:

[0057] First, the second motor 53 directly drives the blade assembly 54 to rotate, and then the third electric push rod 51 pushes the bracket 52 to move at a constant speed. At this time, the bracket 52 will drive the rotating blade assembly 54 and the second motor 53, which is the power source, to move together until the blade assembly 54 contacts the aluminum plate and performs the cutting operation on the positioned and fixed aluminum plate. Continue to move forward until the aluminum plate is completely cut.

[0058] In addition, when the bracket 52 moves, it will also drive the sliding sleeve 55 to move, and make the sliding sleeve 55 slide on the surface of the crossbar 56. The sliding connection between the sliding sleeve 55 and the crossbar 56 not only supports the bracket 52, but also ensures its stability when it moves.

[0059] In addition, when the sliding sleeve 55 moves, it will also drive the connecting seat 61 and the connecting block 62 to move together, so as to facilitate the subsequent adjustment of the height position of the mounting seat 66 and its bottom brush group 67.

[0060] like Figure 8 , 9 As shown in Figure 10, the cleaning mechanism 6 includes a connecting seat 61, a fixing plate 63, and a limiting rod 65. The connecting seat 61 is fixedly installed on the outside of the sliding sleeve 55. A connecting block 62 is fixedly installed at one end of the connecting seat 61. A fixing plate 63 is fixedly installed in the middle of one side of the inner cavity of the box 1. Springs 64 are welded to both ends of the bottom of the fixing plate 63. A mounting seat 66 is welded to the bottom end of the springs 64. A brush assembly 67 is bolted to the bottom of the mounting seat 66.

[0061] Limiting rods 65 are fixedly installed at both ends of the top of the mounting base 66. The limiting rods 65 are located inside the spring 64. The top of the mounting base 66 slides through to the top of the fixing plate 63. An inclined block 68 is fixedly installed on the top of the mounting base 66. The ground of the connecting block 62 is in contact with the inclined surface of the inclined block 68. With the cooperation of the above components, the track 44 and the base plate 45 can be directly contacted, and the tops of both can be cleaned.

[0062] During cleaning:

[0063] First, adjust the height of the mounting base 66 and its bottom brush assembly 67. When the sliding sleeve 55 moves, it will also drive the connecting base 61 and the connecting block 62 to move together. At this time, the blade assembly 54 is not rotating. Then, during the movement, the connecting block 62 will move on top of the inclined block 68. Since one end of the top of the inclined block 68 is inclined, the connecting block 62 will press down on the inclined block 68 when it moves. After being subjected to force, the inclined block 68 will push the mounting base 66 to move downward. The mounting base 66 will stretch the spring 64, and the limiting rod 65 will slide through the fixing plate 63 and move downward, causing the brush assembly 67 to contact the track 44 and the base plate 45, or the brushes in the brush assembly 67 to bend, which will stop the movement of the connecting block 62. Then, driven by the moving mechanism 4, it will complete the moving brush grabbing operation and can be used in conjunction with the collection mechanism 7 for unified collection and processing.

[0064] Furthermore, during cleaning, you need to move it to the desired position first, then lower the brush group 67, and finally move it again to perform the brush cleaning work.

[0065] Furthermore, the collection mechanism 7 includes a hanging component and a receiving component. The hanging components are respectively disposed at both ends of the base plate 45, and the receiving component is disposed on the outside of the hanging components.

[0066] As shown in the figure, the hanging assembly includes baffles 71, which are fixedly installed at both ends of the base plate 45. Sliding grooves 73 are provided at both ends of the outer side of the baffles 71.

[0067] The receiving assembly includes a slider 74 and a collection frame 75. The slider 74 is slidably connected inside the chute 73, and the collection frame 75 is fixedly installed on the outside of the slider 74. The baffle 71 has a material port 72 on its outside.

[0068] The baffle 71 is bolted to both ends of the base plate 45. When collection is required, the collection frame 75 is installed in advance, the collection frame 75 is removed, and the slider 74 inside the collection frame 75 is placed above the chute 73. Then it is moved downwards, and the chute 73 and the slider 74 are slidably connected. It is moved downwards until it can no longer move. The aluminum powder that is cleaned outwards will fall directly into the collection frame 75 through the opening 72 for collection. When the required amount is collected, the collection frame 75 is removed and replaced with a new one. The operation is repeated to complete the collection and unified processing of aluminum powder.

[0069] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
