Description

Technical Field

[0001] The present invention relates to the technical field of metal cutting, and in particular to an energy-saving and environment-friendly automatic aluminum removal device for cans. Background Art

[0002] Cans are primarily made of two materials: iron and aluminum. Different materials require different recycling methods: iron and aluminum have different physical and chemical properties, requiring different processing techniques after recycling. For example, aluminum has a relatively low melting point, making it suitable for recycling through specialized smelting techniques; iron, on the other hand, is harder and may require more robust machining. Separating the iron and aluminum from cans allows for more efficient and specialized recycling of different materials, improving resource utilization. Mixing iron and aluminum for recycling cans can reduce the quality of the recycled products. For example, the introduction of iron impurities into recycled aluminum can reduce the purity of the aluminum, lowering its performance and value. Separating the iron and aluminum ensures a purer recycled iron and aluminum, resulting in higher-quality recycled iron and aluminum products. Existing methods for removing aluminum from cans often rely on manual labor, which is not only time-consuming and labor-intensive, but also poses significant safety risks.

[0003] A query of the known prior art shows that: "CN 114346308 B, a resource recycling can aluminum dismantling device" records "The present invention relates to a can aluminum dismantling device, in particular to a resource recycling can aluminum dismantling device. The technical problem to be solved is: to provide a resource recycling can aluminum dismantling device with low risk and capable of cooling the blade. The technical solution of the present invention is: a resource recycling can aluminum dismantling device, comprising a base plate, a first support frame, a first connecting rod, a first fixed plate, a first fixed rod, a roller, a second fixed plate, a first slide rail, a first movable plate, a first spring, a second fixed rod, a second movable plate and a blade, a first support frame is provided on one side of the top of the base plate, and a first connecting rod is provided on the side of the first support frame away from the base plate. The cylinder of the present invention controls the first movable rod to move to the right, so that the first rack drives the third gear and the movable ring to rotate, and then drives the first gear to rotate, so that there is no need to manually rotate the first gear."

[0004] However, the aforementioned prior art can stripping devices still suffer from the following problems: First, the loading of cans in these prior art can stripping devices still relies on manual labor, requiring workers to pick up and snap each can into place. This structure works well for small-batch can stripping operations, but is unsuitable for large-scale stripping operations, resulting in low efficiency. Second, the prior art can stripping devices are relatively simple in structure, resulting in poor performance. Further analysis reveals that prior art cans come in a wide variety of sizes and materials. Furthermore, the widths required to cut aluminum caps vary during stripping operations, while the cutting blades in these stripping devices are fixed and cannot be adjusted adaptively. After a period of use, the cutting blades are prone to jamming when cutting thicker cans or when cutting the seams of thick, hard can bodies. Conventional cutting blades lack self-protection capabilities and are prone to damage, which can interrupt stripping operations and hinder progress. Third, the prior art can aluminum removal device only has a cutting mechanism, and the aluminum lids and can bodies after being cut still need to be manually collected, which is an unreasonable structural design and time-consuming and labor-intensive. Furthermore, when the exposed cutting blade cuts the metal, waste chips are easily splashed and pungent friction fumes are generated, posing a significant safety hazard to the health of workers.

DETAILED DESCRIPTION

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] It should be noted that, in the specific embodiments of the present invention, terms such as "first" and "second" and other relational terms that may appear are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, terms such as "include", "comprise" or any other variants thereof that may appear are intended to cover non-exclusive inclusion, so that a process, method, article or device that includes a series of elements includes not only those elements, but also other elements that are not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the phrase "including a ..." or other defined elements that may appear does not exclude the presence of other identical elements in the process, method, article or device that includes the elements.

[0031] In the description of the present invention, unless otherwise expressly specified or limited, the terms "mounted," "connected," "connected," and "provided with" should be understood in a broad sense. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0032] Example: Figures 1 to 8 As shown: An energy-saving and environmentally friendly can aluminum stripping automatic device, including a disassembly box 1, a feeding structure 2, a cutting structure 3 and a purification structure 4. The present invention has a reasonable structural design, compact space, and a simple manufacturing process. Compared with traditional can aluminum stripping devices, the length can be compressed by more than 30% and the material saving is more than 20%. The disassembly box 1 is vertically distributed. In order to ensure the horizontal effect of the aluminum stripping device as a whole and the disassembly box 1, the preferred technical solution is as follows: Figure 1 As shown: an adjustment pin 14 is also provided at the lower end of the disassembly box 1. The adjustment pin 14 is threadedly connected to the support leg through a connecting rod 15 to complete the horizontal adjustment of the disassembly box 1. The adjustment pin and the connecting rod are an integrally formed structure, and there are multiple adjustment pins distributed at the four corners. With this arrangement, the disassembly box can be smoothly set and adjusted by rotating the adjustment pins. A feeding channel 11 adapted for conveying cans is provided on the left side of the disassembly box 1, and a first storage chamber 12 and a second storage chamber 13 distributed on the left and right are also provided inside; specifically, the second storage chamber is on the right side of the feeding channel for storing the aluminum caps after cutting and disassembly, and the first storage chamber is below the feeding channel for storing the can bodies after cutting and disassembly.

[0033] like Figure 2 As shown, a material box 5 is also provided on the left side of the disassembly box 1. To further optimize the separation of mixed items during initial loading and ensure smooth cutting and disassembly of the cans, in a further preferred technical solution, the top of the material box 5 is an open structure, and a filter screen 51 is provided at the bottom of the material box 5. The filter screen 51 has a conical or circular concave shape, and a waste material chamber 52 is provided below the filter screen 51. The waste material chamber 52 is provided with a waste drawer cabinet 53 with a movable pull-out structure. In actual can disassembly operations, the raw materials of cans are collected in various forms, and most of them are stored in bags, which easily mixes with debris. During the initial centralized loading of materials, manual cleaning is required, which is time-consuming and labor-intensive. Therefore, the present technical solution uses a filter screen for centralized filtration. The mesh diameter of the filter screen is large enough to ensure that the cans are intercepted, and the debris is filtered out by the screen and enters the waste drawer cabinet for centralized recycling and reprocessing, saving time and effort.

[0034] like Figure 1As shown: In this embodiment, the material box 5 is connected to the feeding channel 11 of the disassembly box 1 through the feeding structure 2. Considering the space required for subsequent cutting and disassembly, the height of the disassembly box should be greater than that of the material box. At the same time, the material box should also ensure the convenience of loading, and the height should be set lower. Figure 3 As shown, the feeding structure 2 includes a feeding auger 21, a support frame 22, a conveyor belt 23, and a guide member 24. The feeding auger 21 is arranged at an angle, with the input end connected to the material box 5 and the output end facing the conveyor belt 23. The feeding auger structure is conventional, so its principle will not be described in detail. The support frame 22 is generally arranged left and right. To ensure the stability of the can feeding and transmission, in the preferred technical solution, the support frame 22 includes a fixed plate 221, a main shaft 222, a secondary shaft 223, and support legs 224. The two fixed plates 221 are symmetrically arranged front to back and extend left to right. The main shaft 222 and secondary shaft 223 are respectively arranged on the right and left sides of the front and rear fixed plates 221 to form a rectangular frame structure. The conveyor belt 23 is arranged on the support frame 22 in a left and right distribution. Specifically, the conveyor belt 23 is arranged between the main shaft 222 and the secondary shaft 223, and the main shaft 222 is also connected to a drive motor 225. The supporting legs 224 are multiple and symmetrically arranged below the fixed plates 221. With this arrangement, when the drive motor is activated, it will drive the main shaft to rotate synchronously, which in turn drives the conveyor belt to rotate. The conveyor belt is generally horizontally distributed, providing the driving force for the automated conveying of cans.

[0035] like Figure 3As shown: In this embodiment, the guide member 24 is configured to adjust the preset width of the can conveying line to complete the orderly output of the can monomers to the feeding channel 11. In order to further ensure that the cans are conveyed one by one in an orderly manner and provide convenience for subsequent cutting, in the preferred technical solution, the guide member 24 is divided into two groups symmetrically distributed front and back, and each group of the guide member 24 includes a guide plate 241, an auxiliary plate 242 and an adjusting screw 243. The guide plate 241 is divided into a first part 244 with an arc structure and a second part 245 with a straight structure. The two are integrally formed, and the guide plate 241 is made of elastic material; it plays a good guiding role. The left end of the first part 244 is connected and fixed to the fixed plate 221, and the right end of the second part 245 extends into the feeding channel 11; the space between the two second parts is the key to the precise conveying of the cans. Therefore, it is necessary to facilitate adjustment for cans of different models and sizes. The auxiliary plates 242 are vertically distributed on the fixed plate 221, and the adjusting screw 243 passes through the auxiliary plates 242 and is connected to the guide plate 241 at the connection between the first part 244 and the second part 245 via a bearing. The end of the adjusting screw 243 is also connected to either a rotary knob or a rotary motor; with this arrangement, manual adjustment and automatic adjustment methods can be used in parallel, and the best one can be used. A scale line 246 is also provided on the adjusting screw 243; and the central axis of the two guide plates 241 symmetrically distributed front and back is consistent with the central axis of the feed channel 11. The purpose of this arrangement is that when the conveyor belt transports the cans brought by the feed auger, it is necessary to guide the cans to be transported in the axial direction, that is, the width is adapted to the distance between the two second parts, providing precise guidance. Specifically, by rotating the adjusting screw, the adjusting screw will move back and forth, thereby driving the distance between the two second parts to be adjusted. The structural design of the present invention is reasonable, which avoids the safety hazards caused by manual disassembly of cans in the prior art. By setting the coordination of the feeding auger, support frame, conveyor belt and guide parts, it realizes automated and efficient feeding and precise guided transportation, providing a strong foundation for the subsequent can disassembly process.

[0036] In this embodiment, to ensure that the aluminum lids of cans are transported on the right side, a visual sensor can be installed on the outer wall of the disassembly box, located at the feed channel, and in conjunction with a mechanical arm, a rotary motor, and a claw structure to achieve reversal. The visual sensor is used to detect whether the aluminum lids of the cans are on the right side. The specific detection point or identification point is the opening in the aluminum lid. The working principle and circuit structure of this visual sensor are prior art and will not be described in detail here. If the visual sensor detects a hole in the aluminum lid of the can, it determines that the can is in the correct position for transport and disassembly. If the visual sensor detects that the aluminum lid of the can does not have a hole, it determines that the can is in the incorrect position for transport and disassembly and needs to be reversed. A support arm is installed on the side wall of the disassembly box, the support arm is arranged horizontally, and the mechanical arm is arranged vertically and mounted on the support arm. The mechanical arm is retractable, the top end of the mechanical arm is connected to the rotary motor to achieve 180-degree rotation, and the bottom end of the mechanical arm is connected to a claw for grabbing the can. This ensures that the aluminum lids of the cans are always on the right side, facilitating the automated cutting and disassembly operation of the cutting knife.

[0037] like Figure 4 As shown in the figure: In this embodiment, the cutting structure 3 includes a first pneumatic arm 31, a pressing plate 32, a baffle 33, a second pneumatic arm 34, a mounting seat 35 and a cutting knife 36. Figure 5 As shown: the first pneumatic arm 31 is vertically distributed in the disassembly box 1 and is located directly above the feeding channel 11. The pressing plate 32 is an arc-shaped structure and is fixedly installed on the end of the first pneumatic arm 31; the pressing plate 32 is located above the first storage cavity 12. In this arrangement, when the can is moved to the specified position, specifically the right side wall of the aluminum cover of the can maintains top pressure contact with the baffle, the first starting arm starts to extend, and then drives the pressing plate downward to complete the pressing of the can to ensure its stability. The baffle 33 is distributed front and back in the disassembly box 1 and is located on the right side of the feeding channel 11 to complete the limiting action of the position of the single can; this arrangement is to ensure that the can is moved to a position where it can be cut and disassembled. For details, refer to Figure 6 As shown: the second pneumatic arm 34 is vertically distributed at the top of the disassembly box 1 and is located between the first pneumatic arm 31 and the baffle 33. The mounting base 35 is provided at the end of the second pneumatic arm 34, and the cutting knife 36 is connected to the mounting base 35 via a central axis 37 and is connected to a cutting motor 38. With such an arrangement, the telescopic change of the second pneumatic arm will drive the cutting knife to move up and down, thus completing the aluminum removal operation of the cans. An air pump is provided on one side of the disassembly box to drive the pneumatic arm. The electricity required for the electrical structural features of this embodiment is driven by connecting an external power supply.

[0038] like Figure 6As shown, a speed sensor 39 is provided on the central shaft 37, and the speed sensor 39 maintains a signal connection with the second cylinder arm. The speed sensor is used to detect the speed of the cutting blade. When the speed sensor detects an abnormal decrease in the speed of the cutting blade, the cutting blade is self-protected, avoiding the problem that traditional cutting blades lack self-protection capabilities and are easily damaged, thereby interrupting the aluminum stripping operation and affecting the progress of the operation. The cutting blade 36 is located above the second storage chamber 13; a third pneumatic arm 310 is also provided on one side of the disassembly box 1. The third pneumatic arm 310 is distributed front and back and is connected to a push plate 311 at its end to automatically store the can body after disassembly. With this arrangement, when the cutting blade is stripping the aluminum of the can, the aluminum cap will enter the second storage chamber. When the third pneumatic arm extends, the can body slides down into the first storage chamber under the action of the push plate. The first pneumatic arm, pressing plate, baffle, second pneumatic arm, mounting base and cutting knife are further coordinated to realize cutting of aluminum lids of different widths for different models of cans, thereby completing reasonable and efficient cutting and disassembly operations on the basis of protecting the cutting tools; at the same time, the speed sensor maintains a signal connection with the second cylinder arm. When the speed of the speed sensor decreases abnormally, the second cylinder arm contracts to drive the cutting knife to separate from the can, which can complete the self-protection of the cutting knife, ensure the safe use of the cutting knife, and further improve the cutting efficiency of the cans and the service life of the tool; the cutting and disassembly process is optimized, the metal cutting operation is smoother, the impact and vibration during the cutting process are reduced, and the influence of external noise is reduced.

[0039] like Figure 5 As shown, the position spacing between the baffle 33 and the cutting blade 36 is adjustable. To achieve cutting of aluminum lids of different sizes and widths for cans of different sizes, thereby achieving efficient and effective cutting and disassembly operations while protecting the cutting blades, a further preferred technical solution is that the rear wall of the disassembly box 1 is provided with two mounting plates 16, one on each side. A guide rod 17 and a rotating rod 18 are provided parallel to each other between the two mounting plates 16. The rotating rod 18 is located in front of the guide rod 17 and is connected to a moving motor 19. One end of the baffle 33 passes through the guide rod 17 and the rotating rod 18, maintaining a sliding connection between the baffle 33 and the guide rod 17, and a threaded rotational connection between the baffle 33 and the rotating rod 18. With this configuration, the moving motor uses a servo-controlled motor, which provides more precise distance control and adjustment. When the moving motor is activated, it drives the rotating rod to rotate synchronously, which in turn drives the baffle on the rotating rod to move left and right. The position of the cutting knife is limited to avoid abnormal cutting caused by the cutting knife moving back and forth. The baffle is movable, so the distance between the baffle and the cutting knife can be adjusted at will. It has a wide range of applications and can adapt to the different aluminum dismantling needs of various can models and specifications.

[0040] like Figure 4 As shown: In this embodiment, to further avoid the problem of high temperatures generated by the cutting tool, optimize the structural design, and improve the efficiency and lifespan of the cutting tool, a preferred technical solution includes a water tank 6 installed on one side of the disassembly box 1. The water tank input is connected to a water inlet pipe. A water pump 61 is installed in the water tank 6. The output of the water pump 61 is connected to a water spray pipe 62. The water spray pipe 62 is a hose with a flexible tube 63 installed on the outside of the water spray pipe 62. An infrared sensor 64 is installed in the disassembly box 1 to detect the reset of the cutting tool. The infrared sensor 64 maintains a signal connection with the water pump 61. With this configuration, the cutting tool temperature increases after a certain period of use. When the cutting knife completes the current can aluminum removal process and resets and rises, the infrared sensor detects the cutting knife and triggers a start signal to the water pump. The water pump starts to spray water through the water pipe. The end of the water pipe can be connected to an atomizing nozzle to improve the spray cooling effect of the tool. A flexible pipe is provided as an external support for the water pipe. The purpose is to adjust the angle at will within the limited space in the disassembly box and always ensure that the end of the water pipe is facing the cutting knife.

[0041] like Figure 7 As shown: In this embodiment, in order to realize the automatic storage of the disassembled can body and aluminum cover in different zones, optimize the structural design, reduce the participation of manual work, and further improve the efficiency of the aluminum disassembly operation of the can, a further preferred technical solution is that the first storage chamber is located below the feeding channel. Figure 7 As shown, an inclined drainage plate is provided on the front side of the feeding channel, so that the can body of the aluminum-removed can can be pushed into the collection cabinet in the first storage chamber by the push plate. The first storage chamber 12 is also adapted to be installed with a collection cabinet 110, and a slide rail 111 is provided at the bottom end of the first storage chamber 12, and a pulley 112 is provided at the bottom end of the collection cabinet 110, and the pulley 112 is matched with the slide rail 111; such an arrangement facilitates pulling and moving to realize the transfer of materials. A strong magnet sub-block 113 is also provided on the rear wall of the collection cabinet 110, and a strong magnet mother block 114 is provided on the rear wall of the first storage chamber 12, and the strong magnet sub-block 113 is matched with the strong magnet mother block 114; the purpose of such an arrangement is to improve the stability of the adaptation installation of the two. The second storage chamber 13 has the same structure as the first storage chamber 12. The present invention further adopts two storage cavities in conjunction with a pull-out and sliding collection cabinet to realize the automatic storage of disassembled can bodies and aluminum covers in partitions, optimizes the structural design, and has a compact structure. Compared with traditional can aluminum disassembly devices, the length can be compressed by more than 30%; the material is saved by more than 20%, which effectively reduces the manufacturing cost, simplifies the manufacturing process, improves the structural balance, reduces the participation of manual labor, and further improves the efficiency of can aluminum disassembly operations.

[0042] like Figure 5As shown: In this embodiment, the purification structure 4 is configured to adjust different wind speed modes to complete the filtration and purification of waste smoke and the screening of aluminum materials when different types of cans are being removed and cut. In order to improve the energy-saving and environmental protection effect of the automatic aluminum removal device for cans, and to avoid the waste flying and hurting people and the pungent smoke generated by cutting and damaging the health of workers, in the preferred technical solution, specific reference is made to Figure 8 As shown: the purification structure 4 includes a dust box 41, a filter element 42 and a dust suction fan 43. The dust box 41 is arranged at the bottom of the second storage chamber 13 and is located below the cutting knife 36; the top of the dust box 41 is provided with a screening mesh 44 with an inclined structure of left high and right low; such a configuration facilitates the automatic sliding of the aluminum cover into the collection cabinet of the second storage chamber, and the smoke generated by the cutting will pass through the screening mesh and enter the dust box when the dust suction fan is started. At the same time, the metal scraps generated by the cutting knife when cutting and dismantling the aluminum cans will also be blocked in the disassembly box, and most of them will pass through the screening mesh into the dust box and be intercepted at the filter element. The filter element 42 is adapted to be installed in the dust box 41 and close to the screening mesh 44.

[0043] like Figure 8 As shown: wherein, the dust suction fan 43 is fixedly installed on the dust suction box 41 through a bracket, and is away from the screening net 44. The output end of the dust suction fan 43 is connected to the outside through a pipe, specifically, the rear end of the dust suction fan is connected to the outside through a pipe. And the dust suction fan 43 includes three modes: low speed, medium speed and high speed. In order to achieve the rational allocation and use of resources, further ensure the environmental protection effect and disassembly efficiency of the aluminum disassembly device, the filter element 42 must be easy to replace and cost-effective. In the further preferred technical solution, please refer to Figure 8 As shown, the filter element 42 includes a breathable non-woven fabric 45, an activated carbon layer 46, and a HEPA air filter cotton 47; the activated carbon layer 46 is arranged in front of the HEPA air filter cotton 47, and the two are wrapped by the breathable non-woven fabric 45 to form an integrated structure. With this arrangement, when the cutting knife begins to remove aluminum from the cans, the dust suction fan is activated, and the dust suction fan collects pungent smoke and small particles of waste in the dust collection box. The pungent smoke and small particles of waste are then adsorbed and filtered by the filter element layer by layer and discharged to the outside through the pipeline. This improves the energy-saving and environmental protection effect of the automatic can aluminum removal device, avoids the problems of waste flying and injuring people, and the health damage of workers caused by pungent smoke generated by cutting, meets the requirements of energy conservation and environmental protection, and further improves the safety and cleanliness of can aluminum removal.

[0044] In a preferred technical solution, an electrical control cabinet can be installed outside the dismantling box, and a PLC controller can be installed inside the electrical control cabinet. The specific control circuit of the PLC controller is common knowledge to those skilled in the art and will not be described in detail. The PLC controller is connected to the motor and pneumatic arm respectively to realize automated control of the aluminum dismantling operation.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
