Description

Technical Field

[0001] This application relates to the fields of mechanical manufacturing and automation, and in particular to an automatic collection and sorting device for iron filings. Background Technology

[0002] The metal manufacturing industry is now widespread across various sectors. With continuous improvements in production efficiency and technology, there is a growing emphasis on increasing resource recycling rates in the production process. This is particularly true in the context of mass production and customized manufacturing of metal parts, where efficient management and utilization of waste has become a crucial issue. Traditionally, workers manually clean the cutting residue around the machine tool after each part is machined, then recycle and reuse the residue. However, this method is not only labor-intensive but also prone to problems such as the mixing of iron filings of different materials due to negligence or misjudgment, severely impacting the quality and efficiency of subsequent iron filings recycling.

[0003] Regarding the aforementioned technologies, the inventors believe that manually cleaning and sorting iron filings is both time-consuming and imprecise, often resulting in different types of metal filings from the same batch being mixed together. This makes it difficult to ensure that even some materials do not meet the standards for reuse. Therefore, there is an urgent need for an automatic iron filings collection and sorting device to solve these problems. Summary of the Invention

[0004] To overcome the above-mentioned technical problems, this application provides an automatic iron filings collection and sorting device.

[0005] This application provides an automatic iron filings collection and sorting device, which adopts the following technical solution:

[0006] An automatic iron filings collection and sorting device includes a collection device for collecting and transporting iron filings processed by a machine tool. The system includes: an oil circulation device for storing, supplying, and recovering oil; a screening device comprising a screening box with a horizontally arranged dividing mechanism that divides the screening box into two chambers; a first discharge port and a second discharge port located above the dividing mechanism and below the dividing mechanism; a connecting device for connecting the oil circulation device, the collecting device, and the screening box; a stirring device with a drive device connected to the screening box for stirring the liquid inside the screening box; a discharge pipe for discharging the mixture of iron filings and oil from the screening box; two discharge pipes, one connected to the first discharge port and the other connected to the second discharge port; and a filtering device with one end connected to the discharge pipe and the other end connected to the oil circulation device for separating iron filings and oil.

[0007] By employing the above technical solution, different types of iron filings naturally stratify in the oil due to their density differences. Lighter iron filings float on top, while heavier ones sink to the bottom. By positioning the first and second discharge ports above and below the separating mechanism, respectively, the iron filings can be effectively collected and classified. Simultaneously, the separating mechanism within the screening box ensures that different types of iron filings do not mix excessively during separation, further improving the accuracy and efficiency of iron filings classification. Furthermore, the use of an oil circulation device not only guarantees a continuous oil supply but also reduces resource waste through recycling. The addition of a stirring device enhances the mixing of iron filings and oil, effectively preventing mixing and promoting uniform distribution of the iron filings, further improving the classification effect.

[0008] Preferably, the collecting device includes a support frame, on which a robotic arm is mounted, and an electromagnet block is mounted at the transmission end of the robotic arm, the electromagnet block being able to enter the connecting device.

[0009] By adopting the above technical solution, this collection device utilizes a combination of a robotic arm and an electromagnet to achieve precise collection and efficient transfer of iron filings after machine tool processing. The flexibility of the robotic arm allows the electromagnet to accurately move to a designated position in complex working environments, ensuring that the iron filings are reliably attracted and transported to the connecting device. This design not only improves the efficiency of iron filings collection but also reduces the need for manual operation, lowers labor intensity, and ensures a clean and safe working environment.

[0010] Preferably, the oil circulation device includes an oil storage tank, one end of which is connected to an oil supply pipe, which is connected to the connecting device. A power pump is installed on the oil supply pipe, and the device also includes several return pipes, one end of which is connected to the oil storage tank.

[0011] By adopting the above technical solution, the oil storage tank in the oil circulation device can effectively store and supply oil. The oil supply pipe transports the oil to the screening box, the power pump ensures a stable supply of oil, and the return pipe recovers the used oil back to the oil storage tank, forming a closed-loop circulation system. This ensures a continuous supply and efficient utilization of oil, while reducing oil waste and improving the system's environmental performance. Furthermore, by adjusting the oil density, this device can be used for sorting different types of metals.

[0012] Preferably, the separating mechanism includes a rotating motor disposed on one side of the screening box, the rotating motor having a rotating gear at its transmission end, the rotating gear meshing with a transmission rack, the transmission rack moving horizontally toward the screening box, the transmission rack being connected to a separating plate, the separating plate being horizontally disposed, the separating plate slidingly passing through the screening box, and the separating plate being able to divide the screening box into two sets of cavities after moving.

[0013] By adopting the above technical solution, the separating mechanism can effectively divide the internal space of the screening box, allowing the upper and lower layers of oil to be separated. A rotating motor drives a rotating gear, which in turn moves a transmission rack horizontally, causing the separating plate to slide within the screening box, ultimately forming two independent chambers. This ensures that different mixtures of oil and iron filings can be discharged from the first and second outlets respectively, without the iron filings re-mixing during the discharge process. This not only improves the oil separation efficiency but also avoids the problem of low separation purity caused by iron filings.

[0014] Preferably, the connecting device includes a connecting pipe, one end of which is connected to the oil circulation device and the other end is connected to the screening box. An openable inlet is provided above the connecting pipe, through which the collecting device can enter the connecting pipe.

[0015] By adopting the above technical solution, the connecting pipe of the connecting device can effectively connect the oil circulation device and the screening box, ensuring smooth oil flow. At the same time, the openable feed port at the top of the connecting pipe facilitates the collection device to send iron filings into the connecting pipe, improving the convenience and efficiency of iron filings transportation.

[0016] Preferably, the stirring device includes a spiral conduit arranged around the screening box, at least one sliding magnet is slidably connected inside the spiral conduit, one end of the spiral conduit is connected to a stirring power pump, and both ends of the spiral conduit are connected to the oil circulation device.

[0017] By adopting the above technical solution, a spiral conduit is arranged around the screening box, and at least one sliding magnet is slidably connected inside. Driven by a power pump, the magnet moves along the spiral conduit, attracting iron filings and generating a strong stirring effect. This design effectively prevents iron filings from entangled, thus avoiding poor separation. Simultaneously, both ends of the spiral conduit are connected to an oil circulation device, enabling oil recycling, reducing resource waste, and improving the overall performance of the system.

[0018] Preferably, the filtration device includes a vertically arranged screening pipe connected to the discharge pipe, a screening pump installed on the screening pipe, a transfer chamber connected to the ground end of the screening pipe, the transfer chamber connected to the oil circulation device, a butterfly valve installed inside the screening pipe, a plurality of flow holes provided on the butterfly plate of the butterfly valve to prevent iron filings from passing through the flow holes, a discharge port provided on the transfer chamber, the axis of the discharge port coinciding with the axis of the screening pipe in the vertical direction, and a switch valve provided at the connection between the discharge port and the transfer chamber.

[0019] By adopting the above technical solution, the filtration device can effectively separate iron filings and oil. Specifically, the vertically arranged screening pipe and screening pump can increase the flow rate of iron filings and oil, ensuring that the iron filings pass smoothly through the screening pipe into the transfer chamber. The flow hole design on the butterfly valve prevents iron filings from passing through when the butterfly valve is closed, thus achieving effective separation of iron filings and oil. When the butterfly valve is open, it allows iron filings to flow out. The design of the transfer chamber further ensures complete separation of iron filings and oil, while facilitating subsequent processing. The axis of the discharge port coincides with the axis of the screening pipe in the vertical direction, ensuring smooth discharge of iron filings, while the on / off valve facilitates control of the discharge process.

[0020] Preferably, it also includes a cleaning device, which includes a cleaning tank disposed below the discharge port. The cleaning tank is used to hold cleaning liquid, and the opening of the cleaning tank points towards the discharge port. An ultrasonic cleaning module is disposed inside the cleaning tank.

[0021] By adopting the above technical solution, this automatic iron filings collection and sorting device can effectively clean and sort iron filings during the discharge process. Specifically, the cleaning tank located below the discharge port can receive the iron filings discharged from the screening device. The cleaning fluid can effectively remove oil and other impurities from the surface of the iron filings, ensuring their cleanliness. At the same time, the ultrasonic cleaning module in the cleaning tank can generate high-frequency vibration, further improving the cleaning effect and making the iron filings cleaner, facilitating subsequent processing or reuse.

[0022] Preferably, it further includes a discharge mechanism, which includes a flipping base plate, a support seat is provided on one edge of the flipping base plate, a flipping plate is rotatably connected to the support seat plate, a cleaning tank is provided on the flipping plate plate, a connecting seat is slidably connected to the side of the flipping plate plate pointing towards the flipping base plate, and a hydraulic rod is vertically provided on the flipping base plate, the other end of the hydraulic rod being rotatably connected to the connecting seat plate.

[0023] By adopting the above technical solution, this automatic iron filings collection and sorting device not only achieves effective separation of iron filings and oil, but also further improves the automation level of iron filings processing. Specifically, the design of the discharge mechanism allows the cleaning tank to automatically tilt, ensuring that the cleaned iron filings can be smoothly discharged, avoiding manual intervention and improving work efficiency. At the same time, the use of hydraulic rods ensures the stability and reliability of the tilting process, reducing equipment failure rate. Furthermore, the ultrasonic cleaning module inside the cleaning tank effectively removes residues from the surface of the iron filings, ensuring the cleanliness of the iron filings and meeting the requirements of subsequent processes.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. By setting up a screening device, the density difference of different iron filings is utilized to further distinguish different types of iron filings through buoyancy, which improves the classification accuracy of iron filings and enables iron filings to be recycled and reused more effectively.

[0026] 2. The design of the stirring device ensures that the iron filings and oil are fully mixed, preventing the iron filings from clumping and tangling, thereby improving the separation effect of the iron filings and oil;

[0027] 3. The collection device employs a robotic arm and an electromagnet. This integrated system accurately identifies and grasps iron filings of various shapes and sizes. The robotic arm's flexible range of motion and adaptability to complex environments enable efficient collection in diverse work scenarios, significantly improving the efficiency and reliability of iron filings recycling. Furthermore, the application of the electromagnet achieves contactless grasping of the iron filings, avoiding potential damage or contamination that can occur with traditional methods, further enhancing the recycling quality.

[0033] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0034] This application discloses an automatic iron filings collection and sorting device. (Refer to...) Figure 1 An automatic iron filings collection and sorting device, comprising:

[0035] Collection device 1 is used to collect and transport iron filings after machine tool processing. The collection device 1 is located between the machine tool and the automatic iron filings collection and sorting device. It uses magnetic force and magnetization and a flexible robotic arm 102 to adsorb iron filings from the metal processing machine tool and sends the adsorbed iron filings into the screening device 3 through the connecting device 4.

[0036] Oil circulation device 2, oil injection device is used to store, supply and recover oil. Oil circulation device 2 stores oil and uses a pump to provide power for oil output and recovery. The oil can be used as a shut-off device and as a power source for other devices, simplifying the mechanism.

[0037] The screening device 3 is used to separate different iron filings. The screening device 3 is located on the left side of the oil circulation device 2. After the iron filings enter the screening device 3, the screening device 3 processes the iron filings by utilizing the differences in the different iron filings, so as to separate the iron filings.

[0038] The stirring device 5 and the driving device are connected to the screening box 301 and are used to stir the liquid in the screening box 301. The stirring device 5 is arranged around the screening device 3 and achieves the stirring and mixing effect by driving the screening device 3 or the objects in the screening device 3.

[0039] The discharge pipe 6 is used to discharge the iron filings and oil mixture in the screening box 301. There are two discharge pipes 6, one set of which is connected to the first discharge port 303 and the other set of which is connected to the second discharge port 304.

[0040] The filter device 7 is connected at one end to the discharge pipe 6 and at the other end to the oil circulation device 2. It is used to separate iron filings and oil. The filter device 7 assists the screening device 3 in distinguishing and collecting iron filings and realizing the circulation of oil.

[0041] Connecting device 4 is used to connect oil circulation device 2, collection device 1 and screening box 301. Connecting device 4 is located between screening device 3 and collection device 1. Two sets of connecting devices 4 are connected to screening device 3 and are used to discharge iron filings screened by screening device 3.

[0042] In practice, iron filings are collected from the metal processing equipment by the collection device 1 and sent to the connecting device 4. Then, the oil circulation device 2 uses a pump to flush the iron filings from the connecting device 4 into the screening device 3. It should be noted that this mechanism can make the overall structure more compact. After that, the iron filings are screened and separated by the screening device 3. The separated iron filings mixed with oil enter the connecting device 4. The connecting device 4 sends the mixture into the filter device 7. Further, the filter device 7 separates the iron filings and oil. The oil is removed by the oil circulation device 2, thus completing the separation of iron filings.

[0043] refer to Figure 2Specifically, the screening device 3 includes a screening box 301, which is a cylindrical body with a horizontally oriented axis. A dividing mechanism 302 is horizontally arranged on the screening box 301. In a preferred embodiment, the dividing mechanism 302 can divide the screening box 301 into two equal parts. This arrangement is intended to accommodate different proportions of iron filings as much as possible. The dividing mechanism 302 is used to divide the screening box 301 into two sets of cavities to prevent the separated iron filings from mixing again when the oil and iron filings mixture is discharged after separation. Several one-way valves for air intake can be provided on the cylinder to cooperate with the dividing mechanism and subsequent discharge steps to prevent the contents of the cylinder from affecting subsequent steps. The screening box 301 is provided with a first discharge port 303 and a second discharge port 304. The first discharge port 303 is located above the dividing mechanism 302 and is used to discharge iron filings with a density lower than that of the oil after screening. The second discharge port 304 is located below the dividing mechanism 302 and is used to discharge iron filings with a density higher than that of the oil after screening.

[0044] refer to Figure 2 Specifically, in one embodiment, the collecting device 1 includes a support frame 101, on which a robotic arm 102 is mounted. An electromagnet block 103 is mounted on the transmission end of the robotic arm 102. The electromagnet block 103 can enter the connecting device 4. The electromagnet is powered intermittently. When on a machine tool, the electromagnet is energized and becomes magnetic, collecting and adsorbing iron filings from the machine tool. Through the movement of the robotic arm 102 on the machine tool, it can adsorb iron filings multiple times, cleaning the machine tool. After adsorption, the electromagnet block 103, through the movement of the robotic arm 102, moves the electromagnet... Block 103 is delivered into the connecting device 4. At this time, the electromagnet is de-energized, and the robotic arm 102 moves, causing the iron filings to fall into the connecting device 4. When there is a large amount of iron filings, the oil circulation device 2 can be used to inject oil into the screening box 301, flushing the iron filings in the connecting device 4 into the screening box 301. After some of the iron filings are flushed, the electromagnet will send the iron filings back into the connecting device 4. The above actions are repeated until the screening box 301 is full or the iron filings are collected. As another embodiment not shown, the iron filings can be transported by clamping or other means.

[0045] refer to Figure 2Specifically, the oil circulation device 2 includes an oil storage tank 201, one end of which is connected to an oil supply pipe 202, which is connected to a screening box 301. A power pump 203 is installed on the oil supply pipe 202. It also includes several return pipes 204, one end of which is connected to the oil storage tank 201. A one-way valve for air intake is installed on the oil storage tank 201 to maintain the pressure balance in the oil storage tank 201. The power pump 203 drives the oil into the screening box 301 or other mechanisms. The oil in the oil storage tank 201 is a high-density oil. By adjusting the oil density, the oil density is adjusted to be just higher than the density of one of the metals. The high-density oil can reduce wear when used as hydraulic fluid, and it can also be used in conjunction with the screening device 3 to screen different iron filings.

[0046] refer to Figure 2 Specifically, the separating mechanism 302 includes a rotating motor 3021 disposed on one side of the screening box 301. The rotating motor 3021 has a rotating gear 3022 at its transmission end. The rotating gear 3022 meshes with a transmission rack 3023. The transmission rack 3023 moves horizontally toward the screening box 301. The transmission rack 3023 is connected to a separating plate 3024. The separating plate 3024 is horizontally disposed and slides through the screening box 301. When the rotating motor 3021 is working, the rotating shaft of the rotating motor 3021 drives the transmission gear to rotate. The rotating gear 3022 further drives the rotating rack to move horizontally. The rotating rack drives the separating plate 3024 connected to it to move, so that the separating plate 3024 is inserted into the screening box 301, dividing the screening box 301 into two sets of cavities.

[0047] refer to Figure 2 Specifically: the connecting device 4 includes a connecting pipe 401, one end of which is connected to the oil circulation device 2 and the other end is connected to the screening box 301. A feed inlet 402 that can be opened and closed is provided above the connecting pipe 401. The collecting device 1 can enter the connecting pipe 401 through the feed inlet 402. The feed inlet 402 on the connecting pipe 401 is designed to be openable and closed, which can be coordinated with the pressure inside the oil lifting pipe to prevent iron filings from being trapped inside the connecting pipe 401.

[0048] refer to Figure 3Specifically, the stirring device 5 includes a spiral conduit 501, which surrounds the screening box 301. At least one sliding magnet 502 is slidably connected inside the spiral conduit 501. One end of the spiral conduit is connected to a stirring power pump 503, and both ends of the spiral conduit 501 are connected to an oil circulation device 2. When the stirring device 5 completes stirring, the power pump 203 injects oil into the spiral conduit 501, causing the sliding magnet 502 to move inside the spiral conduit 501. The sliding magnet 502 attracts the iron filings in the screening box 301 through magnetic force, causing the iron filings to move in the screening box 301. By repeatedly moving back and forth in the spiral guide rail, the iron filings in the screening box 301 are fully stirred. In a preferred embodiment, after stirring, the sliding magnet 502 vertically discharges the oil from the spiral conduit 501 to prevent the magnetic force of the sliding magnet 502 from affecting the subsequent discharge of the oil-iron filings mixture.

[0049] In the specific operation of the screening mechanism, the electromagnet block 103 in the collection mechanism first attracts the iron filings. Then, the feed inlet 402 on the screening tube 701 is opened, and the iron filings are placed into the feed inlet 402. After the iron filings are placed in, the feed inlet 402 is closed. Next, the power pump 203 transfers oil to the screening box 301. The oil flows into the screening box 301 through the connecting pipe 401, which also carries the iron filings into the screening box 301. After all the iron filings are in the screening box 301, the stirring device 5 agitates the iron filings in the screening box 301. The stirring device 5 reduces the sticking between the iron filings. After stirring, the mixture is allowed to settle. It should be noted that... Due to the density of the oil, one type of iron filings, which is less dense than the oil, will float on the upper layer of the oil, while the other type, which is denser than the oil, will fall to the lower layer of the oil after settling. At this point, the rotating motor 3021 starts working, causing the partition plate 3024 to divide the screening box 301 into two sets of cavities. It should be noted that dividing it into two sets of cavities can prevent the iron filings after stratification from mixing again due to the flow during discharge. At this point, the different types of iron filings have been screened. The two cavities of the screening box 301 contain mixtures of different iron filings and oil, respectively. The next step is to discharge these mixtures of iron filings and oil from the first discharge port 303 and the second discharge port 304, respectively, and send them into the filter device 7.

[0050] refer to Figure 3Specifically, the filtration device 7 includes a vertically arranged screening pipe 701 connected to the discharge pipe 6. A screening pump 702 is installed on the screening pipe 701. As one embodiment, the screening pump 702 can be a side-suction pump. The end of the screening pipe 701 pointing to the ground is connected to a transfer chamber 703, which is connected to the oil circulation device 2. A butterfly valve 704 is installed inside the screening pipe 701. Several flow holes 705 are provided on the butterfly plate of the butterfly valve 704. Iron filings cannot pass through the flow holes 705. Through the operation of the screening pump 702, the mixture of oil and iron filings is sucked into the screening pipe 701 through the discharge pipe 6. At this time, the butterfly valve 704 is in the closed state, and the oil can pass through the flow holes 705 and enter the transfer chamber 703. The iron filings will be blocked in the screening pipe 701. After the oil enters the transfer chamber 703, it is then... The oil circulation device 2 returns the oil to the oil storage tank 201. The transfer chamber 703 is equipped with a discharge port 706. The axis of the discharge port 706 coincides with the axis of the screening pipe 701 in the vertical direction. A switch valve 707 is installed at the connection between the discharge port 706 and the transfer chamber 703. When the oil falls, the switch valve 707 is in the closed state. After the oil is discharged, the switch valve 707 changes state to open. After the switch valve 707 is open, the butterfly valve 704 rotates, making the butterfly blade vertical. At this time, the iron filings can fall from the screening pipe 701 and into the transfer chamber 703, and then fall from the discharge port 706. The iron filings can be further sent to the cleaning device, which can clean the oil adhering to the iron filings and wash away the rust on the iron filings.

[0051] refer to Figure 3 as well as Figure 4 Specifically, it also includes a cleaning device 8, which includes a cleaning tank 801 located below the discharge port 706. The cleaning tank 801 is used to hold cleaning fluid, and the opening of the cleaning tank 801 points towards the discharge port 706. After the iron filings fall from the discharge port 706, they enter the cleaning tank 801. An ultrasonic cleaning module 802 is installed inside the cleaning tank 801. After the iron filings fall into the cleaning tank 801, the ultrasonic cleaning module 802 starts to work. It uses the high-frequency vibration and cavitation effect generated by ultrasonic waves in the liquid to peel off and remove dirt and impurities from the surface of the iron filings by forming tiny shock waves and local stirring.

[0052] Specifically, it also includes a discharge mechanism 9, which includes a flipping base plate 901. A support base 902 is provided on one edge of the flipping base plate 901. A flipping plate 903 is rotatably connected to the support base 902. A cleaning tank 801 is provided on the flipping plate 903. A connecting seat 904 is slidably connected to the side of the flipping plate 903 pointing towards the flipping base plate 901. It also includes a hydraulic rod 905 vertically provided on the flipping base plate 901. The other end of the hydraulic rod 905 is rotatably connected to the connecting seat 904. After cleaning, the iron filings can be quickly discharged through the discharge mechanism 9. The hydraulic rod 905 extends and lifts the tilting plate 903. The tilting plate 903 rotates around the support base 902. At the same time, the support rod and the connecting base 904 also rotate. The connecting base 904 slides on the tilting plate 903, lifting one side of the cleaning tank 801 and completing the tilting operation of the cleaning tank 801. The iron filings and the cleaning liquid after cleaning are poured out of the cleaning tank 801, completing the rapid discharge.

[0053] In one embodiment, the hydraulic rod 905 is connected to the oil circulation device 2. The hydraulic rod 905, connected to the oil circulation device 2, enables the tilting action of the tilting plate 903 under the power provided by the oil circulation device 2, thereby effectively controlling the discharge process of iron filings in the cleaning tank 801. Simultaneously, utilizing the power source of the oil circulation device 2 avoids the need for a separate power system, simplifying the device structure and reducing costs and maintenance difficulty. Furthermore, the linkage design between the hydraulic rod 905 and the oil circulation device 2 makes the entire system more stable and reliable in operation, improving the degree of automation.

[0054] The implementation principle of the automatic iron filings collection and sorting device according to an embodiment of this application is as follows: different types of iron filings naturally stratify in the oil due to their density differences. Lighter iron filings float on the upper layer, while heavier iron filings sink to the lower layer. By setting the first discharge port 303 and the second discharge port 304 above and below the separating mechanism 302, respectively, the iron filings can be effectively sorted and collected. Simultaneously, the separating mechanism 302 within the screening box 301 ensures that different iron filings do not mix excessively during separation, thereby further improving the accuracy and efficiency of iron filings sorting. Furthermore, the use of the oil circulation device 2 not only ensures a continuous supply of oil but also reduces resource waste through recycling. The addition of the stirring device 5 enhances the mixing of iron filings and oil, effectively preventing iron filings from mixing.

[0055] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
