[0002] As an accessory device with independent functions on CNC machine tools, the chip removal and filtration device's key performance aspects, such as chip removal efficiency, filtration accuracy, and practicality, directly affect the use of CNC machine tools. In the chip removal and filtration system of a CNC machine tool with a quick-change filter screen structure, which is authorized by announcement number CN112872888B, the replacement of the quick-change filter screen requires manual operation, resulting in insufficient automation. When the quick-change filter screen's filtration effect is insufficient, it cannot be replaced in a timely manner. Summary of the Invention

[0003] The purpose of this invention is to provide a chip removal and filtration system for a CNC machine tool with a quick-change filter screen structure, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: A chip removal and filtration system for a CNC machine tool with a quick-change filter screen structure includes a chip removal device. A filter box is connected to one side of the chip removal device. An inlet is provided on the side of the filter box near the chip removal device. A filter module is provided inside the filter box. The filter module includes a used screen, vertical slots, and a vertical plate. Two sets of used screens are symmetrically arranged. The vertical slots are symmetrically opened on both sides of the filter box. The vertical plate slides into the vertical slots and is connected to the used screen. Processing modules are provided on both sides of the used screen. The processing modules include inclined processing frames. The inclined processing frame is located on one side of the old screen, and the transfer frame is located on the other side of the old screen. Both the inclined processing frame and the transfer frame are connected to the filter box. The filter box is symmetrically equipped with replacement modules on both sides. The replacement module includes a top groove, a new screen and a second vertical plate. The top groove, the new screen and the second vertical plate are symmetrically located on the top of the filter box. The top groove is opened on the filter box. The bottom of the top groove is connected to the inner cavity of the filter box and the vertical groove opening, respectively. The second vertical plate is connected to one side of the new screen. The bottom end of the new screen and the bottom end of the second vertical plate are slidably fitted in the top groove.

[0005] Preferably, the processing module further includes a round rod, a baffle, and a drive motor. The round rod is positioned between two sets of old screens, and the outer wall of the round rod is slidably fitted with the old screens. The baffle is connected to the outer wall of the round rod and is positioned between two sets of inclined processing frames. The drive motor is connected to the top of the filter box via positioning bolts and is positioned between two sets of new screens. A gap is left between the drive motor and the new screens. The bottom end of the output shaft of the drive motor passes through the top of the filter box and is connected to the middle of the top of the round rod. The output shaft of the drive motor drives the round rod to rotate, so that the baffle no longer blocks the inclined processing frames corresponding to the old screens that are not in use, but blocks the inclined processing frames corresponding to the old screens that are in use.

[0006] Preferably, the processing module further includes a base plate, a top inclined plate, and a bottom inclined plate. The base plate is connected to the bottom end of the inclined processing frame, the top inclined plate is connected to the top of the base plate, and the bottom inclined plate is located at the top of the inner cavity of the inclined processing frame. The base plate, the top inclined plate, and the bottom inclined plate are all in sliding fit with the inner wall of the inclined processing frame and the old mesh. The inclined structure at the top of the top inclined plate allows the chips to slide off better.

[0007] Preferably, the processing module further includes a lower pressure plate, a primary liquid outlet pipe, a one-way valve, and a secondary liquid outlet pipe. The lower pressure plate is slidably fitted on the top surface of the inner cavity of the transfer frame.

The secondary liquid outlet pipe is connected to the middle of the bottom of the filter box on the side away from the chip removal equipment. The one-way valve ensures that the coolant in the filter box will not flow back into the transfer frame through the primary liquid outlet pipe. A flow sensor is installed on the primary outlet pipe.

[0008] Preferably, the processing module further includes a primary electric telescopic rod, support rods, and a mounting plate. The primary electric telescopic rods are located on the top of the filter box, and there are four sets of primary electric telescopic rods. Each primary electric telescopic rod corresponds to a bottom inclined plate and a lower pressure plate.

The bottom of the output end of the primary electric telescopic rod located above the transfer frame penetrates through the top of the filter box and is connected to the lower pressure plate. The support rods are arranged in a circumferential array on the outside of the primary electric telescopic rods, and the bottom end of the support rods is connected to the filter box. The mounting plate is connected to the top of the support rods and is also connected to the primary electric telescopic rods. The stability of the primary electric telescopic rods is ensured through the support rods and the mounting plate.

[0009] Preferably, the processing module further includes a connecting slot, a connecting plate, a secondary electric telescopic rod, and a collection box. The connecting slots are symmetrically opened on both sides of the bottom of the filter box. The connecting plate is slidably fitted into the connecting slot, and the top surface of the connecting plate is connected to the bottom plate. The collection box is connected to the bottom of the filter box, and the inner cavity of the collection box is connected to the connecting slot. The secondary electric telescopic rod is symmetrically connected to the bottom surface of the inner cavity of the collection box, and the top of the output end of the secondary electric telescopic rod is connected to the connecting plate. The chips are collected through the collection box.

[0010] Preferably, the replacement module also includes a fixing block, a three-stage electric telescopic rod, and a linkage plate. The fixing block is connected to the top of the filter box, the three-stage electric telescopic rod is symmetrically connected to both sides of the fixing block, and the linkage plate is symmetrically located on both sides of the filter box. The output end of the three-stage electric telescopic rod is connected to the linkage plate, and the linkage plate is connected to the first vertical plate through positioning bolts. The output end of the three-stage electric telescopic rod corresponding to the old screen to be replaced drives the linkage plate, the first vertical plate, and the old screen to be replaced to move.

[0011] Preferably, the replacement module also includes a four-stage electric telescopic rod, a longitudinal plate, and a positioning frame. The longitudinal plate is connected to the top of the second vertical plate by positioning bolts. The four-stage electric telescopic rod is located above the longitudinal plate, and the bottom of the output end of the four-stage electric telescopic rod is connected to the middle of the top of the longitudinal plate. The positioning frame is located on the outside of the second vertical plate, and the top of the four-stage electric telescopic rod is connected to the top of the inner wall of the positioning frame. The output end of the four-stage electric telescopic rod drives the longitudinal plate to descend.

[0012] Compared with the prior art, the beneficial effects of the present invention are: When the old screen needs to be replaced, the present invention automatically removes the chips and coolant from the inclined processing frame and the coolant from the transfer frame to prevent leakage of chips and coolant during the replacement of the old screen. Then, the old screen is automatically pulled out through the replacement module and the new screen is installed between the inclined processing frame and the transfer frame, thereby completing the replacement of the old screen with the new screen, improving the degree of automation, and realizing the replacement without stopping the machine.

[0021] refer to Figures 1-8As shown, the replacement module 6 also includes a fixing block 64, a three-stage electric telescopic rod 65, and a linkage plate 66. The fixing block 64 is connected to the top of the filter box 2. The three-stage electric telescopic rod 65 is symmetrically connected to both sides of the fixing block 64. The linkage plate 66 is symmetrically arranged on both sides of the filter box 2. The output end of the three-stage electric telescopic rod 65 is connected to the linkage plate 66.

The output end of the three-stage electric telescopic rod 65 corresponding to the old screen 41 to be replaced drives the linkage plate 66, the vertical plate 43, and the old screen 41 to be replaced to move.

[0022] refer to Figures 1-8 As shown, the replacement module 6 also includes a four-stage electric telescopic rod 67, a longitudinal plate 68, and a positioning frame 69. The longitudinal plate 68 is connected to the top of the second vertical plate 63 by positioning bolts. The four-stage electric telescopic rod 67 is located above the longitudinal plate 68, and the bottom of the output end of the four-stage electric telescopic rod 67 is connected to the middle of the top of the longitudinal plate 68. The positioning frame 69 is located on the outside of the second vertical plate 63, and the top of the four-stage electric telescopic rod 67 is connected to the top of the inner wall of the positioning frame 69. The output end of the four-stage electric telescopic rod 67 drives the longitudinal plate 68 to descend.

[0023] Working principle: Step 1: The chips and coolant discharged by the chip removal device 1 enter the filter box 2 through the inlet 3 and are filtered by the old screen 41. The coolant is discharged from the filter box 2 through the first-stage outlet pipe 510 and the second-stage outlet pipe 512 in sequence. Under the action of the baffle 54, only one set of old screens 41 will be put into the filtration operation. The flow sensor in the processing module 5 corresponding to the old screen 41 in use monitors the flow rate of the coolant in the first-stage outlet pipe 510. When the flow rate drops to the preset value, it means that the old screen 41 in use needs to be replaced. The flow sensor sends the signal to the peripheral terminal. The peripheral terminal receives the signal and controls the drive motor 55 to start. The output shaft of the drive motor 55 drives the round rod 53 to rotate, so that the baffle 54 no longer blocks the inclined processing frame 51 corresponding to the old screen 41 that is not in use, but blocks the inclined processing frame 51 corresponding to the old screen 41 in use, so as to prevent the continuous entry of chips and coolant from affecting the replacement of the old screen 41. Step Two: After the baffle 54 has rotated, it cannot continue to rotate due to the obstruction of the tilting processing frame 51. The drive motor 55 sends a signal to the peripheral terminal. The peripheral terminal receives the signal and controls the drive motor 55 to shut down. The two sets of primary electric telescopic rods 513 in the processing module 5 corresponding to the old mesh 41 to be replaced open. The output ends of the two sets of primary electric telescopic rods 513 simultaneously drive the bottom tilting plate 58 and the lowering plate 59 to descend. Since the bottom of the bottom tilting plate 58 is a mixture of chips and coolant, the chips are blocked by the old mesh 41 at the bottom of the bottom tilting plate 58, while the coolant is squeezed into the lowering plate 59. Due to the presence of chips... The bottom inclined plate 58 is blocked before the lower pressure plate 59, preventing the output end of the primary electric telescopic rod 513 connected to the bottom inclined plate 58 from descending. The primary electric telescopic rod 513 sends a signal to the peripheral terminal, which receives the signal and controls it to close. When the coolant in the lower pressure plate 59 is discharged through the primary outlet pipe 510, the bottom surface of the lower pressure plate 59 contacts the bottom surface of the filter box 2. The output end of the primary electric telescopic rod 513 connected to the lower pressure plate 59 cannot descend, and the primary electric telescopic rod 513 connected to the lower pressure plate 59 is blocked before the lower pressure plate 59 from descending. The retracting rod 513 transmits a signal to the peripheral terminal. The peripheral terminal receives the signal and controls the primary electric telescopic rod 513 connected to the lower pressure plate 59 to close, while the secondary electric telescopic rod 518 corresponding to the old mesh 41 to be replaced opens. The output end of the secondary electric telescopic rod 518 drives the connecting plate 517, the base plate 56, and the top inclined plate 57 to descend. The top inclined plate 57 detaches from the filter box 2, and the chips slide down the inclined structure of the top inclined plate 57 into the collection box 519. After the output end of the secondary electric telescopic rod 518 retracts, the secondary electric telescopic rod 518 corresponding to the old mesh 41 to be replaced transmits a signal to the peripheral terminal. A terminal is set up. The peripheral terminal receives the signal and controls the output end of the secondary electric telescopic rod 518 corresponding to the old mesh to be replaced 41 to drive the connecting plate 517 to rise. After the output end of the secondary electric telescopic rod 518 corresponding to the old mesh to be replaced 41 has extended, the bottom surface of the base plate 56 is flush with the bottom surface of the inner cavity of the filter box 2, and the top inclined plate 57 is reset. The secondary electric telescopic rod 518 corresponding to the old mesh to be replaced 41 transmits the signal to the peripheral terminal. The peripheral terminal receives the signal and controls the secondary electric telescopic rod 518 corresponding to the old mesh to be replaced 41 to close, and the tertiary electric telescopic rod 65 corresponding to the old mesh to be replaced 41 to open. Step 3: The output end of the three-stage electric telescopic rod 65 corresponding to the old mesh 41 to be replaced drives the linkage plate 66, the vertical plate 43, and the old mesh 41 to be replaced to move. After the output end of the three-stage electric telescopic rod 65 corresponding to the old mesh 41 to be replaced is fully extended, the old mesh 41 to be replaced is completely separated from the filter box 2. The three-stage electric telescopic rod 65 corresponding to the old mesh 41 to be replaced sends a signal to the peripheral terminal. The peripheral terminal receives the signal and controls the three-stage electric telescopic rod 65 corresponding to the old mesh 41 to be replaced to close. The four-stage electric telescopic rod 67 corresponding to the new mesh 62 to be replaced opens. Its output end drives the longitudinal plate 68 and the new mesh 62 to descend until the bottom surfaces of the longitudinal plate 68 and the new mesh 62 are in contact with the bottom surface of the inner cavity of the filter box 2, at which point it can no longer descend. The four-stage electric telescopic rod 67 corresponding to the new mesh 62 to be replaced sends a signal to the peripheral terminal. The peripheral terminal receives the signal and controls the four-stage electric telescopic rod 67 corresponding to the new mesh 62 to close. Step 4: After replacement, open the three-stage electric telescopic rod 65 connected to the old mesh 41 until the linkage plate 66 is in contact with the replaced vertical plate 63. The output end of the three-stage electric telescopic rod 65 connected to the old mesh 41 can no longer retract. The three-stage electric telescopic rod 65 connected to the old mesh 41 sends a signal to the external terminal. The external terminal receives the signal and controls the three-stage electric telescopic rod 65 connected to the old mesh 41 to close. Personnel connect the linkage plate 66 to the replaced vertical plate 63 using positioning bolts to facilitate the automatic removal of the new mesh 62 and vertical plate 63. The vertical plate 62 connected to the replaced vertical plate 63 is then closed. Separate from plate 68 and open the four-stage electric telescopic rod 67 connected to the separated longitudinal plate 68. The output end of the four-stage electric telescopic rod 67 connected to the separated longitudinal plate 68 drives the longitudinal plate 68 to rise. When the output end of the four-stage electric telescopic rod 67 connected to the separated longitudinal plate 68 can no longer retract, the four-stage electric telescopic rod 67 connected to the separated longitudinal plate 68 sends a signal to the external terminal. The external terminal receives the signal and controls the four-stage electric telescopic rod 67 connected to the separated longitudinal plate 68 to close. Personnel then connect the new filter screen that needs to be replaced next to the separated longitudinal plate 68, thereby completing the device reset.
