Description

Technical Field

[0001] This utility model relates to a recycling device, specifically a metal cutting fluid recycling device. Background Technology

[0002] Cutting fluid is an industrial liquid used in metal cutting and grinding processes to cool and lubricate cutting tools and workpieces. It is a scientifically formulated blend of various high-performance additives, possessing excellent cooling, lubrication, rust prevention, degreasing and cleaning, corrosion protection, and easy dilution properties. In the process of machining metal using CNC metal cutting machine tools, to reduce costs and minimize environmental and water pollution, workers often need to recycle and reuse cutting fluid. Because existing cutting fluids contain metal debris of varying sizes, the pore size of the filter screen must be very small to effectively filter these metal debris. As a result, these filters are prone to clogging, which seriously reduces the filtration speed of the cutting fluid to be recycled and greatly decreases the efficiency of recycling cutting fluid. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a metal cutting fluid recycling device. A servo motor drives a transmission mechanism to move a scraper reciprocally across a filter screen, removing metal shavings and other impurities adhering to the screen and effectively preventing filter clogging. This solves the problem that existing cutting fluids contain metal shavings of varying sizes, requiring very small pore sizes in the filter screen for effective filtration, which easily leads to clogging. This significantly reduces the filtration speed of the recovered cutting fluid and greatly lowers the efficiency of the recovery process.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a metal cutting fluid recycling device, comprising a device housing, a filter screen plate fixedly connected to the center of the inner wall of the device housing, a drive seat fixedly connected to the top of the device housing, displacement seats movably connected to both sides of the bottom surface of the drive seat, a transmission assembly disposed at the center of the two displacement seats, the transmission assembly being used to connect the two displacement seats and the drive seat, a scraper movably connected to the bottom end of the displacement seat, the bottom surface of the scraper being in contact with the surface of the filter screen plate, a connecting seat disposed at the top end of the scraper, the top end of the connecting seat extending to the outside of the displacement seat, a buffer assembly disposed between the connecting seat and the displacement seat, the buffer assembly being used to connect the displacement seat and the connecting seat; the transmission assembly... The system includes a servo motor, with a transmission rod fixedly connected to the output end of the servo motor. A lead screw A is rotatably connected to the bottom end of the transmission rod. Both ends of the lead screw A extend to the outside of the displacement seat and are rotatably connected to the drive seat. When the servo motor drives the transmission rod to rotate, the transmission rod transmits the power of the servo motor to the lead screw A, causing the lead screw A to drive the two displacement seats to slide on the bottom surface of the drive seat. The buffer assembly includes a hydraulic rod located at the top of the displacement seat and fixedly connected to the displacement seat. The top end of the hydraulic rod extends to the bottom end of the connecting seat. A connecting spring is fixedly connected to the bottom end of the displacement seat, and the bottom end of the connecting spring extends to the top end of the scraper. When the displacement seat moves, the scraper contacts the surface of the filter screen plate during the movement of the displacement seat.

[0005] Furthermore, storage tank seats are fixedly connected to both sides of the device housing, and a discharge port is provided at the bottom of the device housing. An electronic valve is provided inside the discharge port. When the device is in use, the displacement seat cooperates with the scraper to push the surface of the filter screen plate into the inside of the storage tank seat.

[0006] Furthermore, slots are provided on both sides of the device housing, and the two ends of the storage tank seat are inserted into the inside of the slots, so that the storage tank seat and the device housing are connected by a snap-fit ​​connection.

[0007] Furthermore, a control panel is fixedly connected to one side of the drive unit. The control panel, transmission components, and electronic valve are all integrated into one structure, and the transmission components and electronic valve can be controlled separately through the control panel.

[0008] Furthermore, both sides of the filter screen plate are inclined, and the bottom surface of the scraper is in contact with the surface of the filter screen plate.

[0009] Furthermore, bevel gears are provided at the bottom of the transmission rod and on the outer side of the center position of the lead screw A. When the transmission rod rotates, the transmission rod, in conjunction with the bevel gears, drives the lead screw A to rotate.

[0010] Furthermore, lead screw A is a double-threaded lead screw, with the threads at both ends of lead screw A being symmetrical to each other. When lead screw A rotates, lead screw A drives two displacement seats to move relative to each other on the bottom surface of the servo motor.

[0011] The beneficial effects of this utility model are: This metal cutting fluid recycling device uses a servo motor to drive a transmission mechanism that moves a scraper back and forth on the surface of a filter screen. This removes metal shavings and other impurities adhering to the screen, effectively preventing filter clogging and ensuring continuous and stable filtration of the cutting fluid. The scraper's bottom surface is in close contact with the filter screen surface, and the inclined screen design completely pushes impurities away from the filtration area and guides them into the storage tank. The buffer components (hydraulic rod and connecting spring) work together to ensure that the scraper fits tightly against the screen for efficient scraping, while also providing buffering and floating adjustment capabilities to prevent damage to the scraper or screen due to impact or obstruction by foreign objects.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figures 1-5This utility model provides an embodiment of a metal cutting fluid recycling device, including a device housing 1. A filter screen plate 9 is fixedly connected to the center of the inner wall of the device housing 1. A drive seat 2 is fixedly connected to the top of the device housing 1. Displacement seats 4 are movably connected to both sides of the bottom surface of the drive seat 2. A transmission assembly is provided at the center of the two displacement seats 4. The transmission assembly is used to connect the two displacement seats 4 and the drive seat 2. The transmission assembly includes a servo motor 3. A transmission rod 11 is fixedly connected to the output end of the servo motor 3. A lead screw A10 is rotatably connected to the bottom end of the transmission rod 11. The two ends of the lead screw A10 extend to the outside of the displacement seats 4 and are rotatably connected to the drive seat 2.

[0016] In this embodiment, when the servo motor 3 drives the transmission rod 11 to rotate, the transmission rod 11 transmits the power of the servo motor 3 to the lead screw A10, so that the lead screw A10 drives the two displacement seats 4 to slide on the bottom surface of the drive seat 2.

[0017] It should be noted that bevel gears 12 are provided at the bottom end of the transmission rod 11 and on the outer side of the center position of the lead screw A10. When the transmission rod 11 rotates, the transmission rod 11, in conjunction with the bevel gears 12, drives the lead screw A10 to rotate. The lead screw A10 is a double-threaded lead screw, and the threads at both ends of the lead screw A10 are symmetrical to each other. When the lead screw A10 rotates, the lead screw A10 drives the two displacement seats 4 to move relative to each other on the bottom surface of the servo motor 3.

[0018] Please see Figures 2-3 In this embodiment, storage tank seats 8 are fixedly connected to both sides of the device housing 1. A discharge port is provided at the bottom of the device housing 1. An electronic valve is provided inside the discharge port. When the device is in use, the displacement seat 4 cooperates with the scraper 5 to push the surface of the filter screen plate 9 into the inside of the storage tank seat 8. Both sides of the device housing 1 are provided with slots. The two ends of the storage tank seat 8 are inserted into the inside of the slots. The storage tank seat 8 and the device housing 1 are connected by a snap-fit ​​connection. A control panel is fixedly connected to one side of the drive seat 2. The control panel, the transmission component and the electronic valve are all integrated into one structure.

[0019] In this embodiment, the transmission components and the electronic valve can be controlled separately via a control panel.

[0020] Please see Figures 4-5In this embodiment, a scraper 5 is movably connected to the bottom end of the displacement seat 4. The bottom surface of the scraper 5 is in contact with the surface of the filter screen plate 9. A connecting seat 13 is provided at the top end of the scraper 5. The top end of the connecting seat 13 extends to the outside of the displacement seat 4. A buffer assembly is provided between the connecting seat 13 and the displacement seat 4. The buffer assembly is used to connect the displacement seat 4 and the connecting seat 13. The buffer assembly includes a hydraulic rod 6. The hydraulic rod 6 is located at the top end of the displacement seat 4. The hydraulic rod 6 is fixedly connected to the displacement seat 4. The top end of the hydraulic rod 6 extends to the bottom end of the connecting seat 13. A connecting spring 7 is fixedly connected to the bottom end of the displacement seat 4. The bottom end of the connecting spring 7 extends to the top end of the scraper 5.

[0021] In this embodiment, when the displacement seat 4 moves, the scraper 5 contacts the surface of the filter screen plate 9 during the movement of the displacement seat 4. The two sides of the filter screen plate 9 are set with a sloping structure, which not only helps the scraper 5 to push the impurities away from the main filtration area smoothly, but also allows the impurities to slide quickly into the storage tank seat 8 with the help of gravity, preventing accumulation and backflow, and improving the slag discharge efficiency.

[0022] It should be noted that both sides of the filter screen plate 9 are inclined, the bottom surface of the scraper 5 is in contact with the surface of the filter screen plate 9, and the hydraulic rod 6 provides damping buffer to prevent the scraper 5 from being damaged by impact during rapid movement; the connecting spring 7 gives the scraper 5 a certain floating ability in the vertical direction. When it encounters greater resistance (such as foreign objects getting stuck), it can be moderately compressed to avoid structural overload. The two work together to ensure that the scraper 5 can not only fit tightly against the surface of the filter screen plate 9 (ensuring thorough cleaning), but also has self-adjusting ability to adapt to slight deformation of the screen plate or changes in dirt thickness.

[0023] During operation, the metal cutting fluid, carrying chips and other impurities, enters from the top or side of the device housing 1. It first flows through the filter screen 9 located in the center of the device. The filter screen 9 performs preliminary solid-liquid separation of the cutting fluid; larger metal chips are trapped on the screen surface, while the filtered cutting fluid flows through the screen holes into the lower part of the device, where it is discharged or recycled via the bottom outlet. As the filtration process continues, impurities gradually accumulate on the screen surface, potentially causing blockage. At this point, the power is switched on, the device is started, and the servo motor 3 is activated via the control panel. The output of the servo motor 3 drives the transmission rod 11 to rotate, transmitting power to the lead screw A10 via the bevel gear 12. Because the lead screw A10 has a double-ended symmetrical thread structure, its rotation drives the two displacement seats 4 to move synchronously along the bottom guide rail of the drive seat 2. The scraper 5 moves in opposite directions (i.e., moves left and right), thereby driving the scraper 5 connected to it to slide back and forth on the surface of the filter screen plate 9. During the movement, the scraper 5 pushes the metal shavings and other impurities accumulated on the surface of the screen plate to both sides, and finally guides them to fall into the storage tanks 8 on both sides through the inclined plane, realizing the automatic slag removal function. During the movement of the scraper 5, the hydraulic rod 6 provides damping buffer to prevent the scraper 5 from damaging the screen plate due to impact during rapid movement. The connecting spring 7 gives the scraper 5 a certain floating ability in the vertical direction. When it encounters greater resistance (such as foreign objects stuck), it can be moderately compressed to avoid structural overload. The two work together to make the scraper 5 not only fit tightly against the surface of the filter screen plate 9 (to ensure thorough slag removal), but also have the ability to self-adjust to adapt to slight deformation of the screen plate or changes in dirt thickness.

[0024] It should be noted that the control method of this utility model is controlled by a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art, and the power supply is also common knowledge in the art.
