Description
Technical Field
[0001] This utility model relates to the technical field of recycling devices, specifically a device for circulating and recycling coolant in CNC machine tools. Background Technology
[0002] The CNC machine tool coolant circulation and recovery device is an auxiliary device used in the CNC machine tool machining process. Its main function is to provide coolant to the machine tool spindle, cutting tools, and machining area to reduce the heat generated during cutting, prevent tool wear and workpiece deformation, and flush away chips to keep the machining area clean. The device transports coolant from the storage tank to the machine tool machining area through a circulation system. After use, it collects and filters chips and impurities from the coolant and returns it to the storage tank for recycling, thereby achieving efficient circulation and recovery of coolant. This not only saves resources but also reduces environmental pollution and improves the machining efficiency and stability of CNC machine tools.
[0003] When machining workpieces on CNC machine tools, the sprayed coolant mixes with the chips and flows out together. This mixed state makes the recycling process of coolant and chips complicated. Since the coolant adheres to the surface of the chips, it is difficult to achieve rapid separation of coolant and chips by relying solely on the fluidity of the coolant itself. In addition, some coolant will remain on the surface of the chips, which not only increases the difficulty of chip recycling, but also reduces the quality of chip recycling.

[0028] The sprayed coolant mixes with the chips and flows out together. This mixed state complicates the recycling process of coolant and chips. Since the coolant adheres to the surface of the chips, it is difficult to achieve rapid separation of coolant and chips by relying solely on the fluidity of the coolant itself. In addition, some coolant will remain on the surface of the chips, which not only increases the difficulty of chip recycling but also reduces the quality of chip recycling.
[0029] like Figures 4-6 As shown, the system includes a recycling assembly 2, a drive assembly 1 fixedly connected to the right side of the recycling assembly 2, and a first extrusion conveying assembly 3 and a second extrusion conveying assembly 4 rotatably connected to the inner side of the recycling assembly 2. The drive assembly 1 includes a drive motor 11, the housing of which is fixedly connected to the frame 12. A first gear 13 is fixedly connected to the end of the main shaft of the drive motor 11, and the outer side of the first gear 13 meshes with the outer side of a second gear 14. The second extrusion conveying assembly 4 includes a rotating roller 41, a conveying roller 42 fixedly connected to one side of the rotating roller 41, and a rubber conveyor belt 43 sleeved on the outer side of the conveying roller 42. A liquid inlet 44 is provided on the inner side of the rubber conveyor belt 43, and an airbag ring 45 is fixedly connected to the outer side of the rubber conveyor belt 43. An annular steel sheet 46 is fixedly connected to the outer side of the airbag ring 45, and a seepage hole 47 is provided on the inner side of the annular steel sheet 46. The outer side of the rotating roller column 41 is fixedly connected to the inner side of the second gear 14. During operation, the mixture enters the gap between the two components from the feed inlet 22. The drive motor 11 drives the gear to rotate. The first component rotates faster than the second component, and the mixture is squeezed and conveyed. The coolant flows into the cooling recovery tank 23 through the airbag ring 45, the seepage hole 47, and the liquid inlet 44, realizing separation and recycling, and automatic chip recovery. This device has high separation efficiency and excellent quality, reduces resource waste and pollution, and improves processing efficiency and stability.
[0030] like Figures 2-3As shown, the recycling component 2 includes a housing 21, with an inlet 22 at the top of the housing 21, operation ports 24 at both the left and right ends of the housing 21, and a discharge port 25 at the front end of the housing 21. A cooling recovery tank 23 is fixedly connected to the inside of the housing 21, and an outflow hole is provided at the right end of the cooling recovery tank 23. With the above configuration, this structural design allows the coolant to enter the device through the inlet 22 and be discharged smoothly through the outflow hole, which facilitates the recycling of the coolant.
[0031] like Figure 5 As shown, the component structure of the first extrusion conveying component 3 is the same as that of the second extrusion conveying component 4. A gap is provided between the rear end of the first extrusion conveying component 3 and the rear end of the second extrusion conveying component 4. The bottom end of the first extrusion conveying component 3 is attached to the top end of the second extrusion conveying component 4. With the above arrangement, the first extrusion conveying component 3 and the second extrusion conveying component 4 have the same structure and are attached to each other, which can ensure that the mixture is evenly distributed between the two and effectively extruded. The setting of the gap provides a suitable space for the entry and separation of the mixture, thereby improving the separation efficiency.
[0032] like Figures 2-4 As shown, a shaft hole is opened on the inner side of the outer shell 21, and multiple rotating rollers 41 are rotatably connected to the inner side of the outer shell 21. The right-end rotating roller 41 extends out of the outer side of the outer shell 21. The left side of the frame 12 is fixedly connected to the right side of the outer shell 21. The inner side of the first gear 13 is fixedly connected to the rotating roller 41 of the first extrusion conveying assembly 3. The diameter of the second gear 14 is 1.2 times the diameter of the first gear 13. Through the above settings, the fixed connection between the frame 12 and the outer shell 21 ensures the structural stability of the device. The fixed connection between the first gear 13 and the rotating roller 41 and the diameter ratio design of the second gear 14 and the first gear 13 enable the first gear 13 and the second gear 14 to generate different speeds when rotating, thereby realizing the extrusion and friction separation of the mixture, which significantly improves the separation efficiency and quality.
[0033] like Figures 5-6As shown, the distance between the rear ends of the first extrusion conveyor assembly 3 and the second extrusion conveyor assembly 4 is aligned vertically with the feed inlet 22. The first extrusion conveyor assembly 3 and the second extrusion conveyor assembly 4 extend to the front end of the discharge port 25. The cooling recovery box 23 is located inside the rubber conveyor belt 43 and is aligned vertically with the first extrusion conveyor assembly 3. The liquid inlet 44 penetrates vertically through the inner side of the rubber conveyor belt 43. A gap is provided between the annular steel sheet 46 and the rubber conveyor belt 43. The seepage hole 47 penetrates through the inner side of the annular steel sheet 46. The thickness of the annular steel sheet 46 is 2mm. Through the above settings, it is convenient to collect and discharge the coolant, further improving the separation effect and resource recycling rate of the device. The design of the liquid inlet 44 penetrating the rubber conveyor belt 43 facilitates the flow and discharge of the coolant. The gap between the annular steel sheet 46 and the rubber conveyor belt 43 and the design of the seepage hole 47 penetrating the annular steel sheet 46 enable the coolant to be smoothly separated from the chip surface and discharged. At the same time, the thickness design of the annular steel sheet 46 ensures its strength and deformation during the extrusion process, improving the durability and separation effect of the device.
[0034] In summary, the working principle of this scheme is as follows: When the coolant after CNC cutting is recycled with the chips, the mixture falls through the feed inlet 22 into the gap between the first extrusion conveying assembly 3 and the second extrusion conveying assembly 4, that is, the upper end of the second extrusion conveying assembly 4. The drive motor 11 is started to drive the first gear 13 to rotate, and the first gear 13 drives the meshing second gear 14 to rotate simultaneously. Since the diameter of the second gear 14 is 1.2 times the diameter of the first gear 13, when the first gear 13 and the second gear 14 rotate respectively, the first gear 13 and the second gear 14 each drive the fixed rotating roller column 41 to rotate. The motor drives the conveyor roller 42 to rotate. Through friction, the conveyor roller 42 drives another conveyor roller 42 to rotate via the rubber conveyor belt 43. The rotation of the rubber conveyor belt 43 causes the airbag ring 45 and the annular steel sheet 46 to rotate simultaneously. At this time, the second extrusion conveyor assembly 4 and the first extrusion conveyor assembly 3 rotate simultaneously, with the first extrusion conveyor assembly 3 rotating faster than the second extrusion conveyor assembly 4. As the second extrusion conveyor assembly 4 rotates, it conveys the mixture forward. When the mixture is between the first extrusion conveyor assembly 3 and the second extrusion conveyor assembly 4, the two closely fitting annular steel sheets 46 deform. The annular steel sheets 46 then deform against the airbag ring 45. During compression, the airbag ring 45 also deforms. The airbag ring 45 has a hollow internal structure and is filled with gas. When the airbag ring 45 is compressed, the expansion force of multiple airbag rings 45 causes the two annular steel plates 46 to press tightly together. This, combined with the action of the two annular steel plates 46, compresses the mixture. The coolant in the compressed mixture quickly separates from the chips. The coolant enters between the two airbag rings 45 through the seepage hole 47, and then falls into the cooling recovery tank 23 through the liquid inlet 44. The external water pipe drains out through the outflow hole at the right end of the cooling recovery tank 23, achieving a recycling effect. The annular steel plate 46 at one end rotates at a slower speed, while the annular steel plate 46 at the upper end rotates at a faster speed. Under the staggered action of the two annular steel plates 46, the mixture is not only squeezed, but also rotated by friction. This can significantly improve the uniformity of cooling and separation of the chips. A recovery box is placed at the lower part of the front end of the first extrusion conveying assembly 3. After the chips detach from the front end of the first extrusion conveying assembly 3 and the front end of the second extrusion conveying assembly 4, they automatically fall into the designated recovery box, thereby realizing the recovery of the chips. Based on the above principles, the device can quickly separate the coolant on the chips and improve the separation quality and chip recovery quality.
[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
