The cutting fluid is added to the cooling device of the CNC engraving and milling machine through a refill tank, and then the cutting tools are cooled by the cooling device. When the cutting fluid in the refill tank is used up, cutting fluid needs to be added to the refill tank.
[0003] According to Chinese Patent No. CN211332409U, a cutting fluid adding device for a CNC engraving and milling machine is disclosed. This utility model filters the cutting fluid through a screen to ensure the quality of the added cutting fluid, and removes the clip from the inner cavity of the slot so that the screen can be removed for cleaning, ensuring the screen's performance.
[0004] Regarding the aforementioned patent content, a filter screen is provided to filter the added cutting fluid. However, after prolonged filtration, a large amount of impurities accumulate on the surface of the filter screen. To clean the impurities accumulated on the filter screen, it is necessary to remove the filter screen from the filling tank. After cleaning, it is necessary to reinstall it back into the filling tank, making the cleaning process cumbersome, time-consuming, and labor-intensive, thereby reducing the cleaning efficiency of the impurities accumulated on the surface of the filter screen. Utility Model Content
[0005] Therefore, the purpose of this utility model is to provide a cutting fluid adding device for a CNC engraving and milling machine to solve the technical problem of the inconvenience of cleaning the impurities accumulated on the filter screen.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a cutting fluid adding device for a milling machine, comprising an adding tank body, wherein a cleaning component is provided inside the adding tank body, and the cleaning component includes a rotating shaft disposed inside the adding tank body via a sealed bearing, a filter screen installed inside the adding tank body, and a discharge port opened on the upper side of one side of the adding tank body, a liquid guide plate is installed on the upper side of one side of the filter screen, and a discharge plate is provided on the other side of the filter screen, a scraper is installed at the bottom of the rotating shaft, one end of the rotating shaft extends to the outside of the adding tank body and is connected to a turntable, and a sealing plate is engaged inside the discharge port.
[0007] By adopting the above technical solution, when it is necessary to clean the impurities accumulated on the filter screen, the staff can first pull the sealing plate to move the sealing plate out of the discharge port, at which point the sealing plate will no longer block the discharge port.
[0008] Furthermore, a cover plate is installed on the top of the main body of the adding box via a hinge, and a slot is provided on one side of the top of the main body of the adding box.
[0009] By adopting the above technical solution, the cover can be easily rotated to open or close, and the closed cover can cover the main body of the filling box.
[0010] Furthermore, an insert plate is installed on one side of the bottom of the cover plate, the insert plate is located inside the slot, a slot is opened on one side of the insert plate, and a groove is opened on the upper part of the inside of the adding box body.

[0022] Furthermore, one side of the discharge plate is inclined downward along the direction of the discharge port, and the top of the discharge plate is smooth.
[0023] By adopting the above technical solution, when impurities slide onto the discharge plate, they will slide into the discharge port through the discharge plate, making it convenient to discharge them through the discharge port.
[0024] Furthermore, one side of the liquid guide plate is inclined downward along the direction of the filter screen, and the top of the liquid guide plate is smooth.
[0025] By adopting the above technical solution, the cutting fluid flows through the guide plate to the filter screen, which then filters the cutting fluid.
[0026] In summary, the present invention has the following main advantages:
[0027] 1. This utility model, by incorporating a cleaning component, allows for the removal of accumulated impurities from the filter screen. Workers can first pull the sealing plate to move it out of the discharge port, thus eliminating the blockage. Then, the worker can rotate the scraper clockwise, causing the accumulated impurities on the filter screen to move. When the scraper rotates to the same tilt direction as the discharge plate, the impurities on the scraper will slide onto the discharge plate, then into the discharge port, and finally be discharged. This method allows for quick cleaning of accumulated impurities on the filter screen without disassembling it. After cleaning, simply insert the sealing plate into the discharge port; there is no need to reinstall the filter screen. This makes the cleaning process convenient, reduces operational steps, and improves the efficiency of cleaning accumulated impurities on the filter screen.
[0028] 2. By setting a rotatable scraper, when impurities are found to clog the filter screen, the scraper can be rotated even without removing the impurities from the filter screen. The rotation of the scraper will move the impurities accumulated on the filter screen, allowing the impurities to slide onto the discharge plate first, preventing the impurities from accumulating in a fixed position on the filter screen and avoiding filter screen clogging.

[0037] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.
[0038] The embodiments of this utility model will be described below based on its overall structure.
[0039] Example 1:
[0040] A cutting fluid adding device for a CNC engraving and milling machine, such as Figures 1-7 As shown, the device includes a main body 1 for adding fluid, an internal cleaning assembly 9 for adding fluid, and a cover plate 4 mounted on the top of the main body 1 via a hinge. The cover plate 4 is rotatably connected to the main body 1, allowing it to be opened or closed easily. When closed, the cover plate 4 can cover the main body 1. A pump body 2 is installed at the bottom inside the main body 1. The outlet end of the pump body 2 is connected to a tubing 3 extending to the outside of the main body 1. When the pump body 2 is working, it draws cutting fluid from the main body 1, and the cutting fluid is then transported through the tubing 3. An observation window 13 is provided on the outer surface of the main body 1, allowing staff to observe the amount of cutting fluid inside the main body 1.
[0041] Specifically, the cleaning assembly 9 includes a rotating shaft 901 housed inside the adding tank body 1 via a sealed bearing, a filter screen 904 installed inside the adding tank body 1, and a discharge port 907 located on the upper side of one side of the adding tank body 1. A guide plate 906 is installed on the upper side of one side of the filter screen 904, with one side of the guide plate 906 inclined downwards along the direction of the filter screen 904. The top of the guide plate 906 is smooth, allowing the cutting fluid to flow through the guide plate 906 onto the filter screen 904, enabling the filter screen 904 to filter the cutting fluid. A discharge plate 905 is provided on the other side of the filter screen 904. One side of the material plate 905 is inclined downward along the direction of the discharge port 907. The top of the material plate 905 is smooth. When impurities slide onto the material plate 905, they will slide into the discharge port 907 through the material plate 905, making it easy to discharge through the discharge port 907. A scraper 903 is installed at the bottom of the rotating shaft 901. The bottom of the scraper 903 is in contact with the filter screen 904. When the scraper 903 rotates, it will drive the impurities accumulated on the filter screen 904 to move, making it easy to clean the impurities accumulated on the filter screen 904. The level of the cutting fluid will be lower than the bottom height of the material plate 905.
[0042] Specifically, one end of the rotating shaft 901 extends to the outside of the main body 1 of the adding box and is connected to the turntable 909. A sealing plate 908 is snapped into the inside of the discharge port 907. When it is necessary to clean the impurities accumulated on the filter screen 904, the operator can first pull the sealing plate 908 so that the sealing plate 908 moves out of the discharge port 907. At this time, the sealing plate 908 no longer blocks the discharge port 907. The sealing plate 908 is adapted to the discharge port 907. The sealing plate 908 is made of rubber material. The sealing plate 908 can block the discharge port 907 to prevent the cutting fluid from being discharged through the discharge port 907.
[0043] Example 2:
[0044] Based on the above embodiment 1, in order to facilitate the limiting and fixing of the cover plate 4 and prevent it from rotating at will, the following structure will be set.
[0045] Specifically, a slot 6 is provided on one side of the top of the main body 1 of the filling box, and an insert plate 5 is installed on one side of the bottom of the cover plate 4. The insert plate 5 is located inside the slot 6, and a slot 12 is provided on one side of the insert plate 5. A groove 7 is provided on the upper part of the inside of the main body 1 of the filling box. When the cover plate 4 rotates and covers the top of the main body 1 of the filling box, the cover plate 4 will drive the insert plate 5 to rotate, so that the insert plate 5 rotates into the slot 6. A spring 8 is installed on one side of the inside of the groove 7. One end of the spring 8 is connected to a block 11 extending into the slot 12. When the block 11 moves into the groove 7, it will squeeze the spring 8, so that the spring 8 is compressed, which facilitates the subsequent push of the block 11 to reset and move.
[0046] See Figure 3 , Figure 5 , Figure 6 and Figure 7 The locking block 11 is adapted to the locking slot 12. A pull rod 10 is installed on one side of the locking block 11, which extends through to the outside of the main body 1 of the adding box. One end of the pull rod 10 is connected to a pull plate. When the locking block 11 is inserted into the locking slot 12, the insert plate 5 can be locked and limited, thereby improving the stability of the cover plate 4 and preventing the cover plate 4 from rotating at will.
[0047] Example 3:
[0048] Based on the above embodiment 1, in order to prevent the scraper 903 from rotating smoothly and to avoid the cover plate 4 from obstructing the rotation of the scraper 903, the following structure will be provided at the bottom of the cover plate 4.
[0049] See Figure 2 The cleaning assembly 9 also includes an arc-shaped groove 902 opened at the bottom of the cover plate 4. The length of the arc-shaped groove 902 is the same as the length of the filter screen 904. The arc-shaped groove 902 is located directly above the filter screen 904. The arc-shaped groove 902 is set so that the scraper 903 can rotate smoothly and prevent the cover plate 4 from blocking the rotation of the scraper 903.
[0050] The working principle of this utility model is as follows: First, the operator can observe the amount of cutting fluid inside the main body 1 of the addition tank through the observation window 13. When it is necessary to extract the cutting fluid, the pump body 2 can be started. The operation of the pump body 2 can extract the cutting fluid inside the main body 1 of the addition tank. The cutting fluid then flows out through the infusion hose 3. When it is necessary to add the cutting fluid into the main body 1 of the addition tank, the operator can pull the pull rod 10 through the pull plate. The pull rod 10 will drive the locking block 11 to move, so that the locking block 11 moves out of the locking groove 12 and no longer locks and limits the insertion plate 5. At this time, the cover plate 4 can be opened, and then the cutting fluid can be added from the upper right. The cutting fluid will flow through the liquid guide plate 906 to the filter screen 904, and then be filtered by the filter screen 904 and flow into the lower interior of the main body 1 of the addition tank.
[0051] After the cutting fluid is added, the operator rotates the cover plate 4 and pulls the lever 10, causing the locking block 11 to move into the groove 7. When the insert plate 5 at the bottom of the cover plate 4 is rotated into the slot 6 and the bottom of the cover plate 4 contacts the top of the adding box body 1, the lever 10 is released. At this time, the spring 8 is stretched and pushes the locking block 11 to reset and move, so that the locking block 11 moves into the slot 12 to lock and limit the insert plate 5, and the installation of the cover plate 4 can be completed.
[0052] When it is necessary to clean the impurities accumulated on the filter screen 904, the operator can first pull the sealing plate 908 to move it out of the discharge port 907. At this time, the sealing plate 908 no longer blocks the discharge port 907. Then, the operator can rotate the scraper 903 clockwise. The rotation of the scraper 903 will move the impurities accumulated on the filter screen 904. When the scraper 903 rotates to the same tilt direction as the discharge plate 905, the impurities on the scraper 903 will slide into the discharge plate 905, and then slide into the discharge port 907 and be discharged through the discharge port 907. This method can quickly clean the impurities accumulated on the filter screen 904. After cleaning, simply insert the sealing plate 908 into the discharge port 907.
