Description

Technical Field

[0001] The 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 mainly made of two materials: iron and aluminum. Different materials have different recycling methods: iron and aluminum have different physical and chemical properties, and different processing techniques are required after recycling. For example, aluminum has a relatively low melting point and can be processed through specific smelting techniques during the recycling process; while iron has a higher hardness and may require more powerful mechanical processing during recycling. After separating the iron and aluminum of cans, more efficient and professional recycling can be carried out for different materials, thereby improving the recycling rate of resources. If iron and aluminum are mixed together for recycling, the quality of the recycled products may be reduced. For example, the mixing of iron impurities in the recycling of aluminum products will affect the purity of aluminum and reduce its performance and value. By separating iron and aluminum, it can be ensured that the recycled iron and aluminum materials are purer, thereby producing higher quality recycled iron and recycled aluminum products. However, the existing technology of removing aluminum from cans mostly adopts manual operations, which is not only time-consuming and labor-intensive, but also has great safety hazards.

[0003] A query of the known prior art shows that: "CN 114346308 B, a device for dismantling aluminum from cans for resource recycling" records "The present invention relates to a device for dismantling aluminum from cans, and in particular to a device for dismantling aluminum from cans for resource recycling. The technical problem to be solved is: to provide a device for dismantling aluminum from cans for resource recycling, which has low risk and can cool down the blade. The technical solution of the present invention is: a device for dismantling aluminum from cans for resource recycling, comprising a bottom 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 bottom plate, and a first connecting rod is provided on the side of the first support frame away from the bottom 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 above-mentioned prior art aluminum dismantling device for cans still has the following problems: First, the can loading of the above-mentioned prior art aluminum dismantling device for cans is still done manually, and the staff is required to take and insert them one by one into the designated position. Such a structure is acceptable in the aluminum dismantling operation of small batches of cans, but it is not suitable for large-scale aluminum dismantling operations, resulting in low operating efficiency. Second, the structure of the aluminum dismantling device for cans in the above-mentioned prior art is relatively simple and the use effect is not good. Further analysis is that the specifications and models of the cans in the prior art are various, and the materials are also different; at the same time, during the aluminum dismantling operation, the width of the aluminum cover to be cut is also different, and the cutting knife of the aluminum dismantling device is fixed and cannot be adaptively adjusted. After the cutting knife has been used for a period of time, when cutting thicker cans, or when cutting the edge seam connection of the can body (large thickness and high hardness), the cutting jam phenomenon is easy to occur. The traditional cutting knife does not have the ability to protect itself, and it is very easy for the cutting knife to be damaged, which leads to the interruption of the aluminum dismantling operation and affects the progress of the operation. Third, the above-mentioned prior art aluminum can stripping device only has a cutting structure, and the aluminum cover and can body after the can is cut need to be collected manually, which is unreasonable in structure design and time-consuming and labor-intensive. At the same time, when the exposed cutting knife cuts the metal, it is easy to cause waste chips to splash and produce pungent friction smoke, which poses a great safety hazard to the health of the staff.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

In the absence of further restrictions, the possible appearance of the sentence "including a ..." and other defined elements does not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0022] In the description of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", and "provided with" that may appear should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be internal communication between two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0023] Example: Figures 1 to 8 As shown: an energy-saving and environmentally friendly can aluminum dismantling automatic device, including a dismantling box 1, a feeding structure 2, a cutting structure 3 and a purification structure 4. The invention has a reasonable structural design, compact space, and simple manufacturing process. Compared with the traditional can aluminum dismantling device, the length can be compressed by more than 30% and the material can be saved by more than 20%. The dismantling box 1 is vertically distributed. In order to ensure the horizontal effect of the aluminum dismantling device as a whole and the dismantling box 1, in the preferred technical solution, as Figure 1 As shown: an adjustment pin 14 is also provided at the lower end of the disassembly box 1, and 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. Among them, the adjustment pin and the connecting rod are an integrally formed structure, and there are multiple adjustment pins distributed at the four corners. With such a configuration, the disassembly box can be smoothly set and adjusted by rotating the adjustment pin. A feeding channel 11 adapted for the transportation of 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 cover after cutting and disassembly, and the first storage chamber is below the feeding channel for storing the can body after cutting and disassembly.

[0024] like Figure 2 As shown: wherein, a material box 5 is also provided on the left side of the disassembly box 1. In order to further optimize the separation of the mixed items in the initial loading and ensure the 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 shape of the filter screen 51 is any one of a conical concave structure and a circular concave structure, and a waste cavity 52 is provided below the filter screen 51, and the waste cavity 52 is provided with a waste drawer cabinet 53 adapted to a movable pull-out structure. In the actual can disassembly operation, the raw materials of the cans are collected in various forms, and a bag storage structure is mostly used, which is easy to mix with sundries. When the materials are initially concentratedly loaded, manual cleaning of the workstation is required, which is time-consuming and labor-intensive. For this reason, the technical solution adopts a filter screen for centralized filtration, and the mesh diameter of the filter screen is large enough to ensure that the cans are intercepted, and the sundries are sieved by the screen into the waste drawer cabinet for centralized recycling and reprocessing, saving time and effort.

[0025] 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 24. The feeding auger 21 is tilted, and the input end is connected to the material box 5, and the output end is toward the conveyor belt 23. The structure of the feeding auger is prior art, so its principle is not repeated. The support frame 22 is distributed left and right as a whole. In order to ensure the stability of the can feeding transmission, in the preferred technical solution, the support frame 22 includes a fixed plate 221, a main shaft 222, a secondary shaft 223 and a leg 224. The two fixed plates 221 are symmetrical in front and back and extend left and right. The main shaft 222 and the secondary shaft 223 are respectively arranged on the right and left sides of the two 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 provided with a driving motor 225 connected thereto. There are multiple legs 224, which are symmetrically arranged below the fixed plate 221. With such a configuration, the start of the driving motor will drive the main shaft to rotate synchronously, and then drive the conveyor belt to rotate. The conveyor belt is horizontally distributed as a whole, providing driving force for the automatic transportation of cans.

[0026] 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 monomer 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 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 of an arc structure and a second part 245 of a straight structure, which 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, so it is necessary to facilitate adjustment for cans of different models, specifications and sizes. The auxiliary plate 242 is vertically distributed and arranged on the fixed plate 221, and the adjusting screw 243 passes through the auxiliary plate 242 and is connected to the guide plate 241 through a bearing at the connection between the first part 244 and the second part 245. The end of the adjusting screw 243 is also connected to any one of a rotating knob and a rotating motor; in this way, manual adjustment and automatic adjustment methods are used in parallel and the best one is 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 feeding channel 11. The purpose of such a setting is that when the conveyor belt conveys the cans brought by the feeding auger, the cans are guided to be transmitted in the axial direction, that is, the width is adapted to the distance between the two second parts, which plays a precise guiding role. Specifically, by rotating the adjusting screw, the adjusting screw will move back and forth and drive the distance between the two second parts to be adjustable. The structural design of the present invention is reasonable, which avoids the potential safety hazards caused by manual disassembly of cans in the prior art, and realizes automated and efficient feeding and precise guided transportation by arranging the coordination of the feeding auger, the support frame, the conveyor belt and the guide member, thus providing a strong foundation for the subsequent can disassembly process.

[0027] In this embodiment, in order to ensure that the aluminum cover of the can is transported on the right side, a visual sensor can be set on the outer wall of the disassembly box and located at the feeding channel, and the structure of the mechanical arm, the rotating motor and the claw can be used to achieve reversal. Among them, the visual sensor is used to detect whether the aluminum cover of the can is on the right side. The specific detection point or identification point is the opening of the aluminum cover. The working principle and circuit structure of this part of the visual sensor are prior art, so it is not repeated. If the visual sensor detects that the aluminum cover of the can has a hole, it is determined that the can transmission-disassembly position is correct; if the visual sensor detects that the aluminum cover of the can has no hole, it is determined that the can transmission-disassembly position is wrong and needs to be reversed. A support arm is set on the side wall of the disassembly box, and the support arm is horizontally distributed. The mechanical arm is vertically distributed and arranged on the support arm, wherein the mechanical arm is retractable, and the top of the mechanical arm is connected to the rotating motor to realize the 180-degree rotation function. The bottom of the mechanical arm is connected to the claw for grabbing the can, so that the aluminum cover of the can is guaranteed to be on the right side, which is convenient for the cutting knife to perform automated cutting and disassembly operations.

[0028] like Figure 4 As shown in the 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 chamber 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 a top-pressing 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; in this arrangement, it 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 seat 35 is arranged at the end of the second pneumatic arm 34, and the cutting knife 36 is connected to the mounting seat 35 through the central axis 37, and is connected to a cutting motor 38. In this way, the telescopic change of the second pneumatic arm will drive the cutting knife to move up and down, that is, to complete the aluminum disassembly operation of the can. An air pump is provided on one side of the disassembly box to drive the pneumatic arm. And the electricity required for the electrical structure characteristics of this embodiment is driven by connecting an external power supply.

[0029] like Figure 6As shown: wherein, a speed sensor 39 is provided on the central axis 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 knife. When the speed sensor detects that the speed of the cutting knife is abnormally reduced, the cutting knife is self-protected, thereby avoiding the problem that the traditional cutting knife does not have the ability to self-protect, and the cutting knife is easily damaged, which leads to the interruption of the aluminum dismantling operation and affects the progress of the operation. The cutting knife 36 is located above the second storage chamber 13; a third pneumatic arm 310 is also provided on one side of the dismantling box 1, and the third pneumatic arm 310 is distributed front and back and a push plate 311 is also connected to the end to complete the automatic storage of the can body after the can is dismantled; in this way, when the cutting knife performs the aluminum dismantling process on the can, the aluminum cover will enter the second storage chamber, and when the third pneumatic arm is extended, the can body slides into the first storage chamber under the action of the push plate. The first pneumatic arm, the pressing plate, the baffle, the second pneumatic arm, the mounting base and the cutting knife are further adopted to cooperate with each other to realize the cutting of aluminum caps of different widths for different types 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 and ensure the safe use of the cutting knife, further improving the cutting efficiency of the cans and the service life of the cutting tool; optimizing the cutting and disassembly process, making the metal cutting operation more stable, reducing the impact and vibration during the cutting process, and thereby reducing the influence of external noise.

[0030] like Figure 5 As shown: wherein, the position spacing between the baffle 33 and the cutting knife 36 is adjustable; in order to realize the cutting of aluminum covers of different widths for different types of cans, thereby realizing the reasonable and efficient cutting and disassembly operation on the basis of protecting the cutter, a further preferred technical solution is that the rear wall of the disassembly box 1 is provided with two mounting plates 16 distributed on the left and right, and a guide rod 17 and a rotating rod 18 arranged in parallel are also provided between the two mounting plates 16, and the rotating rod 18 is located on the front side of the guide rod 17, and the rotating rod 18 is also connected to a moving motor 19; one end of the baffle 33 passes through the guide rod 17 and the rotating rod 18, and the baffle 33 and the guide rod 17 are kept in sliding connection, and the baffle 33 and the rotating rod 18 are kept in threaded rotation connection. In this way, the moving motor adopts a servo control motor, and the distance control and adjustment are more precise. When the moving motor is started, it will drive the rotating rod to rotate synchronously, and then drive 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 meet the different aluminum dismantling needs of various can models and specifications.

[0031] like Figure 4 As shown: In this embodiment, in order to further avoid the high temperature problem caused by the cutting tool, optimize the structural design, and improve the efficiency and life of the cutting tool, in the preferred technical solution, a water tank 6 is also provided on one side of the disassembly box 1, and the input end of the water tank is connected to a water inlet pipe.

With this arrangement, when the cutting tool is used for a certain period of time, the temperature of the tool increases. 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 spray pipe. The end of the water spray 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 spray 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 spray pipe is facing the cutting knife.

The present invention further adopts two storage cavities in conjunction with a drawable and slidable collection cabinet to achieve automatic storage of disassembled can bodies and aluminum covers in partitions, optimize the structural design, and have a compact structure. Compared with traditional can aluminum disassembling devices, the length can be compressed by more than 30%, and the material can be saved by more than 20%, which effectively reduces the manufacturing cost, simplifies the manufacturing process, improves the structural balance, reduces the involvement of manual labor, and further improves the efficiency of can aluminum disassembly operations.

[0033] like Figure 5As shown: In this embodiment, the purification structure 4 is configured to adjust different wind speed modes to complete the filtering and purification of waste fume 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 avoid the waste flying and hurting people and the pungent fume generated by cutting to damage the health of workers, in the preferred technical solution, refer 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 net 44 with a left-high and right-low inclined structure; such a configuration facilitates the aluminum cover to automatically slide into the collection cabinet of the second storage chamber, and the smoke generated by the cutting will pass through the screening net 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 disassembling the aluminum cans will also be blocked in the disassembly box, and most of them will pass through the screening net 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 net 44.

[0034] 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, and the output end of the dust suction fan 43 is connected to the outside through a pipeline, specifically, the rear end of the dust suction fan is connected to the outside through a pipeline. And the dust suction fan 43 includes three modes: low speed gear, medium speed gear and high speed gear. In order to achieve the reasonable allocation and use of resources, further ensure the environmental protection effect and disassembly efficiency of the aluminum disassembly device, it is necessary to make the filter element 42 easy to replace and cost-effective. In the further preferred technical solution, 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 on the front side 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 such an arrangement, when the cutting knife starts to remove aluminum from the cans, the dust suction fan is started, and the dust suction fan collects the pungent smoke and small particles of waste in the dust box, and then is discharged to the outside through the pipeline after being adsorbed and filtered by the filter element layer by layer, thereby improving the energy-saving and environmental protection effect of the automatic aluminum removal device for cans, avoiding the problem of waste chips splashing and injuring people and the pungent smoke generated by cutting damaging the health of workers, meeting the requirements of energy saving and environmental protection, and further improving the safety and cleanliness of aluminum removal from cans.
