[0051] In order to facilitate the movement of the support rod 47, a limiting groove 49 is opened on the side surface of the slag separator 4 close to the fixed seat 42, and the surface of the support rod 47 is slidably engaged with the inner wall of the limiting groove 49, and the limiting groove 49 limits the movement of the support rod 47.

[0052] In order to facilitate the discharge of residue, a slag outlet 410 is opened on one side surface of the slag separator 4, and a sealing door 411 is hinged on the surface of the slag outlet 410. When slag discharge is required, the sealing door 411 is opened to open the slag outlet 410, and the residue is discharged from the slag separator 4 under the action of the scraper 48.

[0053] In order to facilitate the movement of the slag tray 4, second self-driving slide rails 412 are fixedly installed on both sides of the upper surface of the filtered water tank 2, and the bottom of the slag tray 4 is fixedly connected to the upper surface of the slider of the second self-driving slide rail 412 to prevent residue on the slag tray 4 from accumulating.

[0054] By setting up a secondary filtering mechanism, the 80-mesh stainless steel filter screen 41 with a pore size of 0.25 mm at the bottom of the slag separator 4 is used to filter out the waste larger than 0.25 mm in the grinding fluid. At the same time, the scraper 48 is used to discharge the waste on the 80-mesh stainless steel filter screen 41 out of the slag separator 4 through the slag outlet 410, thereby achieving the effect of cleaning the slag separator 4. The movement of the slider on the second self-driving slide rail 412 drives the slag separator 4 to move, which facilitates better filtration and avoids waste accumulation.

[0055] In order to completely filter the grinding fluid after being filtered through the 80-mesh stainless steel filter screen 41, a fine filtering mechanism is provided including a non-woven fabric 5, and the filtering accuracy of the non-woven fabric 5 is 0.02 mm.

[0056] In order to clamp the non-woven fabric 5 and prevent the non-woven fabric 5 from being too close to the filtered water tank 2, the fine filtering mechanism also includes a roller 51 fixedly installed on one side of the upper surface of the filtered water tank 2, the non-woven fabric 5 is wound around the surface of the roller 51, and brackets 52 are fixedly installed on both sides of the upper surface of the filtered water tank 2 close to the roller 51. Mounting grooves 53 are opened on the surfaces of the opposite sides of the two brackets 52. The inner walls of the two mounting grooves 53 are both equipped with first bidirectional lead screws 54 through bearings. Stepper motors 55 are fixedly installed on the upper surfaces of the two brackets 52. One end of the output shaft of the stepper motor 55 is connected to the filter 2. One end of the first bidirectional lead screw 54 is fixedly sleeved, and two clamping plates 56 are respectively threadedly sleeved on the surfaces of the two first bidirectional lead screws 54. The surfaces of the two clamping plates 56 are slidably clamped with the inner wall of the mounting groove 53. The surfaces of the clamping plates 56 are in contact with the surface of the non-woven fabric 5. The rotation of the output shaft of the stepping motor 55 drives the first bidirectional lead screw 54 connected thereto to rotate. The rotation of the first bidirectional lead screw 54 is smoothly rotated in the mounting groove 53 through the bearing. The rotation of the first bidirectional lead screw 54 drives the two clamping plates 56 on its surface to move relative to each other, so that the clamping plates 56 can clamp the non-woven fabric 5.

[0057] In order to pull the non-woven fabric 5 so that the non-woven fabric 5 is spread between the filtered water tank 2 and the slag separator 4, the inner surface of the filtered water tank 2 is symmetrically distributed with third self-driving slide rails 57 fixedly installed, the upper surfaces of the sliders of the two third self-driving slide rails 57 are fixedly installed with support plates 58, the upper surfaces of the two support plates 58 are fixedly installed with servo motors 59, one side surface of the two support plates 58 is provided with sliding grooves 510, the inner walls of the two sliding grooves 510 are installed with second bidirectional lead screws 511 through bearings, one end of the output shaft of the servo motor 59 is fixedly sleeved with one end of the second bidirectional lead screw 511, and the surfaces of the two second bidirectional lead screws 511 are respectively Two clamping jaws 512 are threadedly connected, and the surfaces of the two clamping jaws 512 are slidably engaged with the inner wall of the sliding groove 510. The surfaces of the clamping jaws 512 are in contact with the surface of the non-woven fabric 5. The rotation of the output shaft of the servo motor 59 drives the second bidirectional lead screw 511 connected thereto to rotate. The rotation of the second bidirectional lead screw 511 drives the two clamping jaws 512 connected thereto to move relative to each other on the second bidirectional lead screw 511 along the inner wall of the sliding groove 510, so that the clamping jaws 512 can clamp the non-woven fabric 5 and drive the non-woven fabric 5 to be spread on the surface of the filter water tank 2 during the movement of the slider of the third self-driving slide rail 57, so that the non-woven fabric 5 can filter the grinding fluid.

[0058] In order to cut off the non-woven fabric 5 after use, pushing cylinders 513 are symmetrically installed on the inner wall of the filter water tank 2. One end of the piston rod of the two pushing cylinders 513 extends out of the filter water tank 2 and is fixedly connected to a cutting knife 514. The cutting knife 514 connected thereto is driven up and down by the extension and retraction of the piston rod of the pushing cylinder 513, so that the cutting knife 514 can cut the non-woven fabric 5 after use.

[0059] By setting up a fine filtering mechanism, the non-woven fabric 5 with a filtering accuracy of 0.02mm is used to filter out waste larger than 0.02mm in the grinding fluid. At the same time, the non-woven fabric 5 is clamped by the clamping claw 512, and the movement of the slider on the third self-driving slide rail 57 drives the non-woven fabric 5 to be spread between the filter water tank 2 and the slag separator 4. With the cooperation of the splint 56 and the pushing cylinder 513, the cutting knife 514 is convenient to cut off the non-woven fabric 5, thereby achieving the effect of easy cleaning.

[0060] Working principle: When in use, first insert the connecting rod 34 on the filter screen chip box 3 into the slide groove 33 and connect it to the slider on the first self-driving slide rail 31 through the magnet 35, and at the same time, make the magnet 35 at the bottom of the filter screen chip box 3 and the slider on the guide rail 32 correspondingly connected by magnetic attraction;

[0061] Then pull the non-woven fabric 5 on the roll, and then start the stepper motor 55 and the servo motor 59. The rotation of the output shaft of the stepper motor 55 drives the first bidirectional lead screw 54 connected thereto to rotate. The rotation of the first bidirectional lead screw 54 rotates smoothly in the mounting groove 53 through the bearing. The rotation of the first bidirectional lead screw 54 drives the two clamping plates 56 on its surface to approach each other, so that the clamping plates 56 clamp the non-woven fabric 5. At the same time, the rotation of the output shaft of the servo motor 59 drives the second bidirectional lead screw 511 connected thereto to rotate. The rotation of the second bidirectional lead screw 511 drives the two clamping claws 512 connected thereto to approach each other on the second bidirectional lead screw 511 along the inner wall of the sliding groove 510, so that the clamping claws 512 clamp the non-woven fabric 5. Then start the third self-driving slide rail 57, so that the movement of the slider on the third self-driving slide rail 57 drives the non-woven fabric 5 to be laid between the filtered water tank 2 and the slag separator 4.

[0062] The used grinding fluid of the grinding machine workbench 1 is first discharged into the filter screen chip box 3 for filtration. Since the diameter of the circular hole of the filter screen chip box 3 is 2 mm, the waste materials larger than 2 mm in the grinding fluid can be separated in the filter screen chip box 3. At the same time, the first self-driving slide rail 31 is started, so that the movement of the slider on the first self-driving slide rail 31 drives the filter screen chip box 3 to move in the slag separation plate 4.

[0063] The grinding fluid passing through the filter screen chip box 3 is filtered through the 80-mesh stainless steel filter screen 41 on the slag separation plate 4. Since the aperture of the 80-mesh stainless steel filter screen 41 is 0.25 mm, the waste materials larger than 0.25 mm in the grinding fluid can be separated in the slag separation plate 4. At the same time, the second self-driving slide rail 412 is started, so that the movement of the slider on the second self-driving slide rail 412 drives the slag separation plate 4 connected thereto to move;

[0064] The grinding fluid passing through the slag separator 4 is filtered by the non-woven fabric 5. Since the filtering accuracy of the non-woven fabric 5 is 0.02 mm, the grinding fluid used by the five-axis grinder worktable 1 can be completely filtered. The filtered grinding fluid flows into the filter water tank 2, completing the whole set of multi-stage layered filtering operation, and then the suction pump 7 is started. The suction pump 7 guides the filtered grinding fluid in the filter water tank 2 into the collection water tank 6, so as to facilitate the reuse of the grinding fluid;

[0065] When cleaning is required, the filter screen chip box 3 is pulled out, so that the magnet 35 on the connecting rod 34 is separated from the slider on the first self-driven slide rail 31, and the magnet 35 at the bottom of the filter screen chip box 3 is separated from the slider on the guide rail 32, and the filter screen chip box 3 is removed for cleaning. Because the filter screen chip box 3 is small in size, it is convenient for the staff to clean it. Then the sealing door 411 is opened, and the drive motor 43 is started. The rotation of the output shaft of the drive motor 43 drives the screw 45 connected to it to rotate. The rotation of the screw 45 drives the moving block 46 connected to it to move along the inner wall of the groove 44. The movement of the moving block 46 drives the support rod 47 to move along the inner wall of the limiting groove 49. The movement of the support rod 47 drives the scraper 48 to move, so that the scraper 48 can discharge the waste on the 80-mesh stainless steel filter screen 41 out of the slag separation plate 4 through the slag outlet 410. At the same time, the pushing cylinder 513 is started, and the extension of the piston rod of the pushing cylinder 513 drives the cutting knife 514 connected to it to move up and cut off the non-woven fabric 5, and then take away the non-woven fabric 5.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
