Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1 、 2 As shown in Figures 3 and 4, the utility model provides a technical solution: a waste chip collection device for CNC machine tools, comprising: a recycling box 1; a recycling filter assembly is placed on the top of the recycling box 1, the recycling filter assembly comprises a No. 1 pump body 2 and two filter cartridges 6 installed inside the recycling box 1 by bolts, and a diversion part is provided above the filter cartridge 6 for intermittently diverting the liquid discharged from the No. 1 pump body 2 into the filter cartridge 6; a discharge pipe 10 is fixedly installed at the bottom of the filter cartridge 6 and the end thereof passes through one side of the recycling box 1, a sliding baffle 9 for sealing the bottom of the filter cartridge 6 is slidably installed above the discharge pipe 10, and a spiral conveying rod 12 is rotatably connected to the inside of the discharge pipe 10.

[0023] It should be noted that the No. 1 pump body 2 and the No. 2 pump body 17 of the present invention are both centrifugal waste chip pumps. The device is equipped with a timer and a controller. The input end of the No. 1 pump body 2 is inserted into the cutting fluid recovery box at the bottom of the CNC machine tool through a pipe. The No. 1 pump body 2 draws the cutting fluid mixed with debris into the diversion box 3. Under the action of the timer and the controller, the diversion part flips regularly to guide the liquid to different filter cartridges 6. The waste chips accumulate in the filter cartridge 6, and the cutting fluid is discharged along the filter hole and flows to the bottom of the inner wall of the recovery box 1. The No. 2 pump body 17 discharges it into the cutting fluid recovery box again. When the controller controls the diversion part to switch, it controls the No. 1 electric telescopic rod 8 to drive the sliding baffle 9 at the bottom of the filter cartridge 6 that is not inletting water to be pulled out, so that the waste chips in the filter cartridge 6 enter the discharge pipe 10 under the action of gravity, and the spiral conveying rod 12 inside the discharge pipe 10 discharges the waste chips.

[0024] See also Figure 1 As shown, a second pump body 17 is installed on one side of the bottom of the recovery box 1, the input end of the second pump body 17 is connected to the inside of the recovery box 1, and a drain pipe is installed at the output end of the second pump body 17.

[0025] It should be noted that the cutting fluid of the present invention is filtered after entering the filter cartridge 6, and the waste chips remain in the filter cartridge 6. The filtered cutting fluid flows into the recovery box 1 along the filter hole, and the No. 2 pump body 17 discharges the cutting fluid entering the recovery box 1 into the cutting fluid recovery box, making it convenient for it to be recycled.

[0026] See also Figure 2 As shown, the diversion part includes a diversion box 3 fixed to the top of the recovery box 1, and the diversion box 3 is internally rotatably connected to a diversion baffle 4 with a semicircular structure, and the diversion baffle 4 is fixed with a drive shaft, one end of the drive shaft passes through one side of the diversion box 3 and is fixed with a gear 15, and the outer side of the gear 15 is meshed with a rack 14, and a No. 2 electric telescopic rod 16 is fixed to one side of the bracket, and the output end of the No. 2 electric telescopic rod 16 is fixedly connected to the rack 14.

[0027] It should be noted that the diverter baffle 4 of the utility model is made of rubber material, and the straight edge of the diverter baffle 4 is used to guide the water flow. When working, the timer counts, and when the preset time is reached, the No. 2 electric telescopic rod 16 drives the rack 14 to move, and the rack 14 drives the gear 15 to rotate. The gear 15 drives the diverter baffle 4 to rotate through the drive shaft, thereby switching the flow direction of the cutting fluid.

[0028] See also Figure 2 、 3 As shown, filter holes are provided on the side of the filter cartridge 6, and an open cylinder is provided at the top and bottom. Both sides of the diverter box 3 are connected to the filter cartridge 6 through the diverter pipe 5. The bottom of the filter cartridge 6 is fixedly connected to the discharge channel 7, and the sliding baffle 9 is slidably connected to the inside of the discharge channel 7. One end of the sliding baffle 9 is fixedly connected to the No. 1 electric telescopic rod 8, and the output end of the No. 1 electric telescopic rod 8 is fixedly connected to the discharge channel 7.

[0029] It should be noted that, in the present invention, the cutting fluid with debris enters the filter cartridge 6, and the bottom of the filter cartridge 6 is blocked by the sliding baffle 9, so that the cutting fluid flows out from the side and the waste chips accumulate in the filter cartridge 6. When the No. 2 electric telescopic rod 16 drives the rack 14 to drive, thereby switching the flow direction, the No. 1 electric telescopic rod 8 below the filter cartridge 6 corresponding to the blocked diversion pipe 5 is extended, and the No. 1 electric telescopic rod 8 drives the sliding baffle 9 to be pulled out from the middle of the discharge channel 7, and the accumulated debris falls into the inside of the discharge pipe 10. After the timing ends, while the diversion baffle 4 is rotating, the No. 1 electric telescopic rod 8 drives the separated sliding baffle 9 to reset, and the other No. 1 electric telescopic rod 8 drives the sliding baffle 9 to open, and this reciprocating alternation is used to achieve the staggered entry of the waste chips inside the filter cartridge 6 into the discharge pipe 10.

[0030] See also Figure 2As shown, the discharge pipe 10 is fixedly connected to the bottom of the discharge channel 7 , a drainage hole 13 is opened at the bottom of the discharge pipe 10 , a motor 11 is fixedly connected to one side of the discharge pipe 10 , and the output end of the motor 11 is fixedly connected to the spiral conveying rod 12 .

[0031] It should be noted that, in the present invention, the cutting fluid in the debris entering the discharge pipe 10 flows along the drainage hole 13 into the recovery box 1, and the motor 11 drives the spiral conveying rod 12 to rotate, and the spiral conveying rod 12 transports the waste chips inside the discharge pipe 10 from one end, thereby realizing the recovery of the debris.
