Description

Technical Field

[0001] This utility model relates to the field of recycled aluminum production technology and equipment, and more specifically, to a polishing machine. Background Technology

[0002] The recycled aluminum industry achieves resource recycling by recovering, processing, and remelting waste aluminum materials (such as profiles, castings, and aluminum shavings), resulting in significant energy-saving, environmental, and economic benefits. In the recycled aluminum production process, raw material pretreatment is a crucial step, directly impacting the efficiency of subsequent smelting, energy consumption, metal recovery rate, and the quality of the final product.

[0003] However, fine metals with dust or impurities on their surfaces are separated during the sorting process in the sorting workshop. Failure to remove these surface dust and impurities will reduce the sorting efficiency and recovery rate in subsequent processes, thereby increasing production costs.

[0004] For example, application number 202110741545.8 provides a mobile polishing and screening device for pretreatment of recycled aluminum, including a container, a polishing machine, and a screening machine. The container is installed on the ground by several supporting columns and has a sound insulation layer inside. The polishing machine and the screening machine are installed inside the container. The dust outlet of the polishing machine is connected to the feed hopper of the screening machine by a conveyor belt. The polishing machine polishes the waste aluminum and filters out the mud and powder on the surface of the waste aluminum. The screening machine performs multi-stage screening of the polished waste aluminum and collects it. The polishing machine and the screening machine are installed inside the container, which is convenient for movement, installation and use. The waste aluminum is polished and filtered to remove the mud and powder on the surface first, and then multi-stage screening is performed to collect the waste aluminum. This not only reduces the intensity of manual labor or the complicated process of screening with multiple screening equipment, but also improves production efficiency. It also reduces the water consumption in the previous water washing and screening process, saves resources and reduces production costs. For example, application number 201620142037.2 discloses a polishing roller for recycled aluminum, including a rotary drying cylinder. At least one section of the inner side of the rotary drying cylinder is coaxially arranged with a multi-faceted cylinder, and several polishing parts protruding radially inward are distributed on the inner wall of the multi-faceted cylinder. By adopting the above technical solution, the moisture content of the recycled aluminum is reduced, ensuring that the material can be directly fed into the furnace for smelting; the combination of drying and polishing processes makes the recycled aluminum cleaner, reduces smelting time, and is more energy-efficient; the combination of drying and polishing processes also reduces the smoke and dust content during the smelting process, making it more environmentally friendly.

[0005] However, the above solutions all target the surface oxide layer of aluminum, but lack equipment or devices for polishing the surface dust or impurities of the metals separated during the sorting process. Therefore, there is an urgent need for a machine capable of polishing metal surfaces. Utility Model Content

[0023] In this utility model, "first" and "second" do not represent a specific quantity or order, but are merely used to distinguish names.

[0024] like Figures 1-10As shown, a polishing machine according to one embodiment of the present invention includes a frame 1, a cutting device 2, a polishing device 3, a material guiding device 4, and a filter screen. The cutting device 2 is installed on the frame 1 and is used to cut the outer packaging of metal. The polishing device 3 includes a polishing cylinder 31, a polishing part 32, and a first driving device 33. The first driving device 33 is installed on the frame 1 and its output end is horizontally oriented. The first driving device 33 controls the polishing cylinder 31 to rotate around its output end. The polishing cylinder 31 has a cavity inside and a material inlet 311 and a dust outlet 312. The material inlet 311 and the dust outlet 312 are respectively connected to the cavity. The polishing part 32 is installed inside the polishing cylinder 31. The cutting device 2 is located above the polishing cylinder 31. The material guiding device 4 is used to transport the metal from the cutting device 2 to the polishing cylinder 31. The material guiding device 4 is installed on the frame 1. The filter screen (not shown in the figure) is installed at the dust outlet.

[0025] The aforementioned polishing machine, with its frame 1, provides a mounting base for the cutting device 2, polishing device 3, and material guiding device 4. As is well known, in sorting processes, metal is carried in bag-like objects for easy transport between different stages; these bags are typically made of cutable or breakable materials. This application incorporates a cutting device 2, eliminating the need for manual cutting of the outer packaging. The cutting device 2 alone can cut away the metal packaging, allowing the metal to pass through and enter the feeding device 4. The feeding device 4 then transports the metal from the cutting device 2 to the polishing device 3. A polishing cylinder 31 with a polishing element 32 installed in its cavity, controlled by a first driving device 33 to rotate vertically, polishes the metal within the cavity through mutual friction, removing dust and impurities from the metal surface, while also being polished by the polishing element 32, thus improving polishing efficiency. During the feeding phase, the feed inlet 311 of the polishing cylinder 31 receives the metal from the feeding device 4; during the discharge phase, the feed inlet 311 is used to dispose of the metal. A filter screen is installed at the dust outlet 312, allowing dust to pass through the filter and fall into an external recycling device (not shown in the figure) after polishing.

[0026] In one embodiment, the feed inlet 311 and the dust outlet 312 are located at opposite ends of the polishing cylinder 31. When in the feeding state, the feed inlet 311 of the polishing cylinder 31 faces upwards, facilitating the material guiding device 4 to transport the metal to the feed inlet 311 and into the polishing cylinder 31. When in the discharging state, firstly, the feed inlet 311 of the polishing cylinder 31 faces upwards and the dust outlet 312 of the polishing cylinder 31 faces downwards. Then, the operator first allows the dust to pass through a filter and exit from the feed inlet. Finally, the first driving device 33 controls the polishing cylinder 31 to rotate until the feed inlet 311 faces downwards, allowing the metal to exit from the feed inlet 311.

[0027] In one embodiment, the first driving device 33 includes a rotary motor 331 and a connecting assembly 332; the connecting assembly 332 is located inside the polishing cylinder 31 and is fixedly connected to the inner wall of the polishing cylinder 31; the rotary motor 331 is mounted on the frame 1, and the output end of the rotary motor 331 passes through the inner wall of the polishing cylinder 31 and is fixedly connected to the connecting assembly 332. Thus, by fixing the connecting assembly 332 to the inner wall of the polishing cylinder 31 and controlling the rotation of the connecting assembly 332 via the rotary motor 331, the polishing cylinder 31 is driven to rotate.

[0028] The output end of the rotary motor 331 is arranged in a horizontal direction, that is, the output end of the rotary motor 331 rotates around the X-axis.

[0029] In one embodiment, the connecting assembly 332 includes a crossbeam and a plurality of connecting beams. Both ends of the crossbeam are fixedly connected to the inner wall of the polishing cylinder 31. The plurality of connecting beams are perpendicular to the crossbeam and spaced apart along the length of the crossbeam. One end of each connecting beam is fixedly connected to the crossbeam, and the other end is fixedly connected to the inner wall of the polishing cylinder 31. Thus, the crossbeam and connecting beams achieve a fixed connection to the inner wall of the polishing cylinder 31, facilitating the rotation of the polishing cylinder 31 by the rotary motor 331 through the connecting assembly 332. Specifically, the spaced-apart arrangement of the connecting beams facilitates the passage of metal between them, allowing metal to exit through the dust outlet 312 of the polishing cylinder 31.

[0030] In one embodiment, the polishing device 3 further includes a first cover assembly and a second cover assembly. The first cover assembly includes a first cover plate 34 and a first locking member 35. When the polishing cylinder 31 is rotating, the first locking member 35 presses the first cover plate 34 against the feed inlet 311, and the first cover plate 34 is sealed to the feed inlet 311. The second cover assembly includes a second cover plate and a second locking member. When the polishing cylinder 31 is rotating, the second locking member presses the second cover plate against the dust outlet 312, and the second cover plate is sealed to the dust outlet 312. Thus, the opening and closing state of the feed inlet 311 is controlled by the first cover assembly, and the opening and closing state of the dust outlet 312 is controlled by the second cover assembly. When the polishing cylinder 31 rotates to polish metal, the feed inlet 311 is sealed to the first cover plate 34, and the dust outlet 312 is sealed to the second cover plate.

[0031] The first cover plate 34, the first locking element 35, the second cover plate, the second locking element, and the filter screen are all existing technologies and can be purchased in the market according to the model by those skilled in the art, so they will not be described in detail here.

[0032] Preferably, the filter screen is located above the second cover plate along the dust output direction. That is, when dust is to be output, the operator controls the second locking element to open and open the second cover plate, so that the cavity is connected to the external cavity, and the dust passes through the filter screen and the dust outlet in sequence and falls into the external recycling device.

[0033] In one embodiment, the polishing component 32 includes a fixing plate 321 and a plurality of protrusions 322 disposed on the fixing plate 321; the fixing plate 321 is arranged circumferentially along the polishing cylinder 31, and the fixing plate 321 is fixedly connected to the inner wall of the polishing cylinder 31. Thus, by providing the protrusions 322, the polishing efficiency of the metal is improved by utilizing the impact friction between the protrusions 322 and the metal.

[0034] In one embodiment, the number of polishing elements 32 is multiple and they are spaced apart along the axial direction of the polishing cylinder 31. This improves the polishing efficiency of the metal.

[0035] In one embodiment, the material guiding device 4 includes a material guiding tube 41, a vibrator 42, and a control valve 43; one end of the material guiding tube 41 is connected to the cutting device 2, and the other end of the material guiding tube 41 is located above the polishing cylinder 31; the control valve 43 is used to control the metal output state of the material guiding tube 41; the vibrator 42 is mounted on the frame 1 and is used to vibrate the material guiding tube 41. Thus, by providing the vibrator 42, the material guiding tube 41 is vibrated, preventing metal accumulation inside the material guiding tube 41.

[0036] Preferably, the end of the feed tube 41 connected to the cutting device 2 is higher than the other end of the feed tube 41. This ensures that the metal can slide from the cutting device 2 into the polishing cylinder 31.

[0037] The vibrator 42 and the control valve 43 are both existing technologies and can be purchased in the market by those skilled in the art based on their models, so they will not be described in detail here.

[0038] It should also be noted that the tilt angle of the guide tube 41 can be adjusted according to the type and size of the object to be polished.

[0039] In one embodiment, the vibrator 42 includes a mounting base 421 and a vibrator body 422 mounted on the mounting base 421. The mounting base 421 has a channel extending through both ends therethrough. The guide tube 41 passes through the channel and the outer wall of the guide tube 41 contacts the inner wall of the channel. The mounting base 421 is mounted on the frame 1.

[0040] The mounting base 421 and the vibrator body 422 are both existing technologies and can be purchased in the market by those skilled in the art based on the model, so they will not be described in detail here.

[0041] In one embodiment, the feeding device 4 further includes an inner tube 44 and a telescopic device 45. The inner tube 44 is inserted into the end of the feeding tube 41 near the polishing cylinder 31, and the inner tube 44 is slidably connected to the feeding tube 41. The telescopic device 45 is installed on the outer wall of the feeding tube 41, and the telescopic end of the telescopic device 45 passes through the outer wall of the feeding tube 41 and is fixedly connected to the inner tube 44. The telescopic device 45 controls the inner tube 44 to move away from and closer to the feed inlet 311. Thus, when metal needs to be added to the polishing cylinder 31, the first cover plate 34 opens, the telescopic device 45 controls the inner tube 44 to extend into the feed inlet 311, and opens the control valve 43, allowing the metal to enter the inner tube 44 from the feeding tube 41 and thus into the polishing cylinder 31. After the metal addition is complete, the telescopic device 45 notifies the inner tube 44 to exit the feed inlet 311.

[0042] The telescopic device 45 is a cylinder, which is existing technology and can be purchased in the market by those skilled in the art based on the model, so it will not be described in detail here.

[0043] In one embodiment, the cutting device 2 includes a housing 21, a second driving device 22, a cutting element 23 for cutting through the outer packaging of the metal, and a baffle plate 24 for blocking the outer packaging of the metal. The housing 21 is mounted on the frame 1, with an opening at the top and a guide port at the bottom communicating with the guiding device 4. The baffle plate 24 is inclinedly disposed inside the housing 21 and has a clearance hole for the cutting element 23 to pass through. The second driving device 22 is mounted on the outer surface of the housing 21, and its output end extends through the inner wall of the housing 21 into the housing 21. The output end of the second driving device 22 inside the housing 21 is located below the baffle plate 24. The output end of the second driving device 22 is connected to the cutting element 23 and is used to control the rotation of the cutting element 23. The second driving device 22 controls the cutting element 23 to rotate in and out of the clearance hole. Thus, by providing the cutting component 23, the outer packaging is cut; at the same time, by providing the baffle plate 24 with clearance holes, the cutting component 23 can rotate above the upper surface of the baffle plate 24 to cut the outer packaging, and the outer packaging can be blocked, but the metal will not be prevented from entering the box 21.

[0044] One end of the guide tube 41 is connected to the guide port of the housing 21, and the other end is located above the polishing cylinder 31.

[0045] The outer packaging includes, but is not limited to, woven bags, plastic bags, paper bags, and canvas bags.

[0046] In one embodiment, the polishing machine is further provided with a dust cover (not shown) and a dust adsorption device (not shown). The dust cover is installed outside the polishing machine, and the dust adsorption device is installed inside the dust cover to adsorb the dust generated during the polishing process.

[0047] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0048] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
