Description

Technical Field

[0001] This invention relates to the field of mold manufacturing, and more specifically to a recycling device. Background Technology

[0002] CNC milling machines, as core equipment in the field of machining, are widely used in industries such as automobile manufacturing, aerospace, mold processing, and precision instruments. They are mainly used to complete machining processes such as milling, drilling, and boring of metal workpieces. During the machining process, a large amount of iron filings are generated. These iron filings not only affect the cleanliness of the machining environment, but if they accumulate on the worktable, guide rails, cutting tools, and workpiece surfaces, they can also lead to problems such as reduced machining accuracy and accelerated tool wear. At the same time, the iron filings are often mixed with cutting fluid, and directly discarding them not only wastes resources but also pollutes the environment.

[0003] Currently, CNC milling machine chip recycling devices on the market are mainly divided into three categories: manual cleaning, simple mechanical recycling, and integrated recycling. Manual cleaning relies on operators to manually sweep and collect chips, which is labor-intensive and inefficient, and is only suitable for small-batch, low-frequency processing scenarios. Simple mechanical recycling devices can achieve basic chip conveying and recycling, but they have problems such as incomplete recycling, poor separation of chips and cutting fluid, and weak adaptability. Integrated recycling devices have more complete functions, but they are complex in structure, expensive, and difficult to install and modify, making them difficult to popularize in small and medium-sized processing enterprises.

[0004] With the ever-increasing pace of CNC milling machine processing, higher demands are being placed on the efficiency, cleanliness, and automation of chip recycling. The shortcomings of existing chip recycling devices—such as low efficiency, incomplete separation, poor adaptability, and resource waste—are becoming increasingly prominent, posing a key bottleneck to improving CNC milling machine processing efficiency and ensuring processing quality. Therefore, developing a CNC milling machine chip recycling device that features high-efficiency recycling, thorough separation, multi-specification adaptability, low cost, and easy installation has become an urgent need for industry development. Summary of the Invention

[0005] The purpose of this invention is to overcome the above-mentioned technical deficiencies and propose a recycling device to solve the technical problem of low recycling efficiency in the prior art.

[0006] To achieve the above-mentioned technical objectives, the present invention provides a recycling device, including a collection mechanism, comprising a workbench, an air nozzle, and a collection tank.

[0008] In some embodiments, the separation mechanism includes a pump body, a water pipe, and a filter screen. The inlet of the water pipe is located in the collection tank, the filter screen is disposed at the inlet of the water pipe, the pump body is disposed on one side of the collection tank, the outlet of the water pipe is connected to the inlet of the pump body, and the outlet of the pump body is connected to the liquid supply system of the milling machine.

[0009] In some embodiments, the separation mechanism further includes an adjustment component, which includes a buoyancy ring, a guide rail, and a slider. The guide rail is disposed on the inner wall of the collection tank and extends along the height direction of the collection tank. The slider is disposed on the water pipe and is slidably connected to the guide rail. The buoyancy ring is connected to the inlet of the water pipe, and the buoyancy of the buoyancy ring is greater than the weight of the water pipe.

[0010] In some embodiments, the separation mechanism further includes a protective component comprising a protective tube connected to the bottom of the collection tank, the protective tube being aligned with the water pipe, and the inlet of the water pipe engaging with the protective tube under the influence of gravity.

[0011] In some embodiments, the protective assembly further includes a protective cover connected to the top of the protective pipe. When the inlet of the water pipe is connected to the protective pipe, the protective cover abuts against the filter screen. The protective cover is convex conical, and the filter screen is concave conical.

[0012] In some embodiments, the protective component further includes a convex sealing ring and a concave sealing ring, the convex sealing ring being connected to the protective pipe and the concave sealing ring being connected to the water pipe, the convex sealing ring and the concave sealing ring being adapted to each other.

[0013] In some embodiments, the protective assembly further includes a vibration motor installed inside the protective tube.

[0014] In some embodiments, the storage mechanism includes a screw conveyor, a negative pressure adsorbent, and a collection vehicle.

[0015] In some embodiments, the storage mechanism further includes a screen connected to the collection vehicle for collecting metal filings, with a gap between the screen and the bottom of the collection vehicle for allowing cutting fluid to pass through.

[0016] Compared with the prior art, the beneficial effects of the present invention include: the combination of the directional air nozzle and the collection tank forms a full-coverage airflow collection channel.

At the same time, the directional airflow can quickly gather iron filings and cutting fluid, preventing the mixture from accumulating on the worktable surface and ensuring stable processing cycle.

[0019] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0020] This invention provides a recycling device, the structure of which is as follows: Figure 1 - Figure 4 As shown, it includes a collection mechanism 1, a workbench 2, an air nozzle 11, and a collection tank 12. The collection tank 12 is located on one side of the workbench 2, and the air nozzle 11 is located on the other side of the workbench 2. The outlet of the air nozzle 11 faces the collection tank 12. The air nozzle 11 is used to blow iron filings and cutting fluid on the workbench 2 into the collection tank 12. A separation mechanism 3, with its fixed end located on the worktable 2 and its movable end located on the collection tank 12, is used to separate iron filings from the cutting fluid; and, Storage mechanism 4, the inlet of which is connected to the outlet of separation mechanism 3, is used to store iron filings and cutting fluid.

[0021] During operation, after the CNC milling machine 5 starts machining, a mixture of iron filings and cutting fluid is continuously generated and scattered on the worktable 2. At this time, the air nozzle 11 located on one side of the worktable 2 is activated simultaneously, spraying high-pressure airflow towards the collection tank 12 on the other side of the worktable 2. The high-pressure airflow forms a directional air curtain that can fully cover the surface of the worktable 2, quickly blowing the mixture of iron filings and cutting fluid scattered in different areas of the worktable 2 into the collection tank 12 on the other side of the worktable 2, achieving initial collection and gathering of iron filings and cutting fluid, and preventing the mixture from accumulating on the surface of the worktable 2 and affecting machining accuracy. The mixture of iron filings and cutting fluid in the collection tank 12 then enters the separation mechanism 3 located on the worktable 2. The separation mechanism 3 separates the solid iron filings and liquid cutting fluid in the mixture through a filter adapter structure. The iron filings and cutting fluid separated by the separation mechanism 3 then enter the storage mechanism 4, which is also located on the worktable 2.

[0022] In this invention, the directional air nozzle 11 and the collection tank 12 work together to form a fully covered airflow collection channel. Compared with the traditional manual cleaning or partial recycling structure, recycling can be completed simultaneously during the processing without stopping the machine, which greatly improves the recycling efficiency. At the same time, the directional airflow can quickly gather iron filings and cutting fluid, preventing the mixture from accumulating on the surface of the worktable 2 and ensuring a stable processing cycle.

[0023] To expand the purging range of nozzle 11, please refer to... Figure 1 In a preferred embodiment, the collecting mechanism 1 further includes a swing assembly 13, which includes a bracket 131, a rotating rod 132, and a motor 133. The bracket 131 is located on one side of the workbench 2, the rotating rod 132 is rotatably connected to the bracket 131, the motor 133 is mounted on the bracket 131, the output shaft of the motor 133 is connected to the rotating rod 132, and a plurality of air nozzles 11 are spaced apart on the rotating rod 132 along the length of the rotating rod 132.

[0024] During operation, when the CNC milling machine 5 starts machining and a mixture of metal chips and cutting fluid is generated, the motor 133 starts synchronously. The rotational motion of the output shaft of the motor 133 is directly transmitted to the rotating rod 132, causing the rotating rod 132 to reciprocate around the pivot point on the support 131. Since multiple air nozzles 11 are fixedly connected to the rotating rod 132, the swinging of the rotating rod 132 will drive all the air nozzles 11 to reciprocate synchronously, causing the spray range of the air nozzles 11 to expand from the initial central area of ​​the worktable 2 to the two side edges of the worktable 2. During the swinging process, the multiple air nozzles 11 continuously spray high-pressure airflow, forming a dynamic fan-shaped sweeping air curtain. On the one hand, the air nozzles 11, which are evenly distributed along the length of the rotating rod 132, can cover the entire width of the worktable 2, avoiding blind spots in airflow coverage. On the other hand, the reciprocating swing of the rotating rod 132 drives the air nozzles 11 to sweep, so that the airflow can repeatedly act on various areas of the worktable 2 surface, pushing the mixture of iron filings and cutting fluid scattered in different areas toward the collection tank 12 on the other side of the worktable 2.

[0025] To achieve the separation of cutting fluid and metal chips, please refer to... Figure 2 In a preferred embodiment, the separation mechanism 3 includes a pump body 31, a water pipe 32, and a filter screen 33. The inlet of the water pipe 32 is located in the collection tank 12, the filter screen 33 is located at the inlet of the water pipe 32, the pump body 31 is located on one side of the collection tank 12, the outlet of the water pipe 32 is connected to the inlet of the pump body 31, and the outlet of the pump body 31 is connected to the liquid supply system of the milling machine 5.

[0026] During operation, the collection mechanism 1 pushes all the iron filings and cutting fluid mixture on the surface of the workbench 2 into the collection tank 12, where the mixture initially gathers. A filter screen 33 is installed at the inlet of the water pipe 32. When the mixture approaches the inlet of the water pipe 32, the filter screen 33 first intercepts and filters the mixture: solid iron filings, because their particle size is larger than the pore size of the filter screen 33, are blocked outside the filter screen 33 and remain in the collection tank 12, achieving initial separation; the liquid cutting fluid can smoothly pass through the pore size of the filter screen 33 and enter the interior of the water pipe 32, completing the core solid-liquid separation step. The pump body 31 is fixedly installed on one side of the collection tank 12, with its inlet sealed to the outlet of the water pipe 32. When the pump body 31 is started, the internal impeller rotates at high speed, generating negative pressure suction, continuously drawing the clean cutting fluid filtered by the filter screen 33 from the collection tank 12 into the pump body 31 through the water pipe 32. The outlet of pump body 31 is sealed and connected to the fluid supply system of milling machine 5. The clean cutting fluid, which is pressurized and delivered by pump body 31, flows directly into the fluid supply system of milling machine 5 and is reused for machining cooling and lubrication operations of milling machine 5, realizing the closed-loop recycling of cutting fluid.

[0027] To reduce the possibility of iron filings accumulating at filter screen 33, please refer to... Figure 2In a preferred embodiment, the separation mechanism 3 further includes an adjustment component 34, which includes a buoyancy ring 341, a guide rail 342, and a slider 343. The guide rail 342 is disposed on the inner wall of the collection tank 12 and extends along the height direction of the collection tank 12. The slider 343 is disposed on the water pipe 32 and is slidably connected to the guide rail 342. The buoyancy ring 341 is connected to the inlet of the water pipe 32, and the buoyancy of the buoyancy ring 341 is greater than the weight of the water pipe 32.

[0028] During operation, the CNC milling machine 5 continuously pushes the mixture of iron filings and cutting fluid into the collection tank 12, causing the fluid level to gradually rise. At this time, the buoyancy of the buoyancy ring 341 connected to the inlet of the water pipe 32 increases with the rising fluid level. Since the buoyancy of the buoyancy ring 341 is always greater than the weight of the water pipe 32, the buoyancy causes the water pipe 32 to move upwards. Simultaneously, the slider 343 on the outside of the water pipe 32 slides smoothly upwards along the guide rail 342 on the inner wall of the collection tank 12, providing precise guidance for the rise of the water pipe 32 and preventing the inlet from deviating from the fluid level range due to tilting. Throughout this process, the inlet of the water pipe 32 remains submerged below the cutting fluid surface, ensuring that the pump body 31 can continuously draw filtered, clean cutting fluid. When the pump body 31 continuously delivers cutting fluid, or when the amount of iron filings and cutting fluid mixture generated during the machining interval decreases, the fluid level in the collection tank 12 gradually decreases. The volume of liquid displaced by the buoyancy ring 341 decreases accordingly, and the buoyancy it receives decreases simultaneously. However, since the buoyancy is still greater than the weight of the water pipe 32, the buoyancy will cause the water pipe 32 to move slowly downward as the liquid level drops. This ensures that the inlet of the water pipe 32 is always at a reasonable depth below the liquid surface. This prevents the inlet of the water pipe 32 from being exposed due to the liquid level being too low, which would cause air to be sucked in and affect the normal operation of the pump body 31. It also prevents the inlet from being too deep, which would cause large iron filings deposited at the bottom of the collection tank 12 to be sucked in, thus ensuring the filtration effect of the cutting fluid.

[0029] To reduce the likelihood of filter 33 becoming clogged, please refer to... Figure 3 In a preferred embodiment, the separation mechanism 3 further includes a protective component 35, which includes a protective tube 351 connected to the bottom of the collection tank 12. The protective tube 351 is aligned with the water pipe 32, and under the gravity of the water pipe 32, the inlet of the water pipe 32 is connected to the protective tube 351.

[0030] During use, large iron filings or impurities easily accumulate at the bottom of the collection tank 12. The protective pipe 351 is connected to the bottom of the collection tank 12 and aligned with the water pipe 32. When the water pipe 32 connects with the protective pipe 351 under its own weight, the protective pipe 351 forms an isolation channel around the inlet of the water pipe 32. This channel can prevent the iron filings deposited at the bottom of the collection tank 12 from approaching the inlet of the water pipe 32, avoiding large iron filings from accumulating at the filter screen 33 at the inlet of the water pipe 32 and causing blockage, thus ensuring that the filter screen 33 always maintains a clear filtration channel.

[0031] To achieve the self-cleaning function of filter 33, please refer to... Figure 3 In a preferred embodiment, the protective component 35 further includes a protective cover 352, which is connected to the top of the protective pipe 351. When the inlet of the water pipe 32 is connected to the protective pipe 351, the protective cover 352 abuts against the filter screen 33. The protective cover 352 is convex conical, and the filter screen 33 is concave conical.

[0032] During use, the convex conical structure of the protective cover 352 precisely matches the concave conical structure of the filter screen 33. When the water pipe 32 inlet connects with the protective pipe 351, the conical surfaces of the two fit tightly together, forming an annular sealing surface. This sealing surface can completely prevent large iron filings and impurities in the collection tank 12 from entering the filtration area of ​​the filter screen 33, and prevent iron filings from seeping into the water pipe 32 from the edge gaps of the filter screen 33. In addition, the conical surface of the convex conical protective cover 352 has a self-cleaning guiding function. When iron filings or impurities flow to the surface of the protective cover 352 with the cutting fluid, they will slide quickly down the conical surface to the bottom of the collection tank 12 under the action of gravity, and will not accumulate on the surface of the protective cover 352.

[0033] To further improve the sealing between water pipe 32 and protective pipe 351, please refer to... Figure 3 In a preferred embodiment, the protective component 35 further includes a convex sealing ring 36 and a concave sealing ring 37. The convex sealing ring 36 is connected to the protective pipe 351, and the concave sealing ring 37 is connected to the water pipe 32. The convex sealing ring 36 and the concave sealing ring 37 are adapted to each other.

[0034] In use, the convex sealing ring 36 and the concave sealing ring 37 adopt a complementary structural design. When the inlet of the water pipe 32 is connected to the protective pipe 351, the convex sealing ring 36 can be precisely embedded in the groove of the concave sealing ring 37, forming a dual sealing structure of physical fitting seal and elastic compression seal. Compared with a single planar seal, this structure has a larger contact area and more uniform contact pressure, which can completely prevent iron filings and impurities in the collection tank 12 from seeping into the interior of the water pipe 32 through the connection gap between the protective pipe 351 and the water pipe 32.

[0035] To further reduce the possibility of filter 33 becoming clogged, please refer to... Figure 3 In a preferred embodiment, the protective component 35 further includes a vibration motor 38, which is installed inside the protective tube 351.

[0036] During use, the vibration motor 38 generates high-frequency micro-vibrations. The vibration waves are transmitted through the protective tube 351 to the inlet filter screen 33 of the water pipe 32 connected to it, causing the surface of the filter screen 33 to vibrate continuously. Fine iron filings and impurities intercepted by the filter screen 33 will detach from the surface of the filter screen 33 under the action of vibration and slide down the convex conical surface of the protective cover 352 to the bottom of the collection tank 12, completely avoiding the problem of blockage caused by the accumulation and agglomeration of iron filings on the surface of the filter screen 33.

[0037] To collect iron filings, please refer to... Figure 4 In a preferred embodiment, the storage mechanism 4 includes a screw conveyor 41, a negative pressure adsorber 42, and a collection vehicle 43. The screw conveyor 41 is installed at the bottom of the collection tank 12 and extends along the length of the collection tank 12. The inlet of the negative pressure adsorber 42 is located at the bottom of the collection tank 12 and at the end of the screw conveyor 41. The outlet of the negative pressure adsorber 42 is connected to the inlet of the collection vehicle 43.

[0038] During operation, iron filings intercepted by the filter screen 33 of the separation mechanism 3 continuously accumulate at the bottom of the collection tank 12. The drive motor 133 of the screw conveyor 41 drives the screw blades to rotate, and the rotating blades generate axial thrust on the iron filings at the bottom of the collection tank 12. Since the screw blades are arranged along the entire length of the collection tank 12, the accumulated iron filings dispersed in various areas of the collection tank 12 can be pushed in a uniform direction to a designated area at the end of the collection tank 12. The inlet of the negative pressure adsorption machine 42 is aligned with the end outlet of the screw conveyor 41. When the screw conveyor 41 pushes the iron filings to this area, the negative pressure adsorption machine 42 starts synchronously. Its internal fan operates at high speed, creating a high-intensity negative pressure airflow at the adsorption inlet. The resulting adsorption force can quickly suck the concentrated iron filings into the conveying pipe of the negative pressure adsorption machine 42. The outlet of the negative pressure adsorption machine 42 is connected to the inlet of the collection vehicle 43, and the sucked-in iron filings directly enter the interior of the collection vehicle 43 through the conveying pipe.

[0039] To achieve secondary separation of iron filings, please refer to... Figure 4 In a preferred embodiment, the storage mechanism 4 further includes a mesh 44 connected to the collection vehicle 43. The mesh 44 is used to collect iron filings. A gap is left between the mesh 44 and the bottom of the collection vehicle 43. The mesh 44 is used to allow cutting fluid to pass through.

[0040] When in use, the iron filings transported by the negative pressure adsorption machine 42 will inevitably carry a small amount of residual cutting fluid. After the mesh 44 receives the iron filings, its mesh structure allows the residual cutting fluid on the surface of the iron filings to pass through the mesh under the action of gravity and drip into the gap space at the bottom of the collection vehicle 43, thereby achieving secondary separation of iron filings and cutting fluid.

[0041] To better understand this invention, the following is combined with... Figure 1 - Figure 4The working principle of a recycling device according to the present invention is described in detail as follows: After the CNC milling machine 5 starts machining, a mixture of iron filings and cutting fluid is continuously generated and scattered on the worktable 2. At this time, the air nozzle 11 located on one side of the worktable 2 is activated simultaneously, spraying high-pressure airflow towards the collection tank 12 on the other side of the worktable 2. The high-pressure airflow forms a directional air curtain, which can completely cover the surface of the worktable 2, and quickly blow the mixture of iron filings and cutting fluid scattered in different areas of the worktable 2 into the collection tank 12 located on the other side of the worktable 2, realizing the initial collection of iron filings and cutting fluid, and avoiding the accumulation of the mixture on the surface of the worktable 2, which would affect the machining accuracy. The mixture of iron filings and cutting fluid in the collection tank 12 then enters the separation mechanism 3 located on the worktable 2. The separation mechanism 3 separates the solid iron filings and liquid cutting fluid in the mixture through a filter adapter structure. The iron filings and cutting fluid separated by the separation mechanism 3 enter the storage mechanism 4, which is also located on the worktable 2.

[0042] The specific embodiments of the present invention described above do not constitute a limitation on the scope of protection of the present invention. Any other corresponding changes and modifications made in accordance with the technical concept of the present invention should be included within the scope of protection of the claims of the present invention.
