DETAILED DESCRIPTION

[0020] The following is a specific embodiment of the utility model and further describes the technical scheme of the utility model in combination with the drawings, but the utility model is not limited to these embodiments.

[0021] As Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 ​The chip removal device for the CNC machine tool includes a chip removal frame 1, and both sides of the inner wall of the chip removal frame 1 are movably connected with driving rollers 10 through bearings. The outside of the two driving rollers 10 is jointly sleeved with a conveyor belt 6, and a pushing component 2 and a drying box 3 are respectively installed on one side of the top of the chip removal frame 1. The top of the drying box 3 is inlaid with a blowing fan 8, and a heating screen frame 9 is installed on the top of the inner wall of the drying box 3. A cleaning component 7 is installed on the other side of the bottom of the inner wall of the chip removal frame 1, and a driving motor 4 is installed at one end of the chip removal frame 1. The output end of the driving motor 4 is sleeved with a driving gear, and one end of one of the driving rollers 10 is sleeved with a driven gear. The outside of the driving gear and the driven gear is sleeved with a transmission chain, and the cleaning component 7 includes a support bar 72, and the bottom of the support bar 72 is connected to the bottom of the inner wall of the chip removal frame 1. The top of the support bar 72 is connected to a conveying inclined plate 71, and both ends of the conveying inclined plate 71 are connected to baffles 73.

[0022] Both ends of the outside of the conveyor belt 6 are connected with a shielding ring 5, and a plurality of supporting rollers are provided inside the conveyor belt 6. The two ends of the supporting rollers are movably connected to the inner wall of the chip removal frame 1 through bearings.

[0023] The top of the conveying inclined plate 71 contacts the conveyor belt 6, and the top of the baffle 73 is provided with an arc-shaped groove 74. The pushing component 2 includes a limit frame 24, the bottom of which is connected to the top of the chip discharge frame 1. The bottom of the inner wall of the limit frame 24 is connected to the filter frame 27, and one side of the filter frame 27 is provided with a slope.

[0024] The bottom of the limit frame 24 is connected to a collecting bucket 26, and the bottom of the collecting bucket 26 is connected to an outer discharge pipe 25, which is located on the top of the conveyor belt 6. The top of one side of the inner wall of the limit frame 24 is connected to a cleaning plate 21. An electric telescopic rod 22 is installed on one side of the limit frame 24. The telescopic end of the electric telescopic rod 22 passes through the interior of the limit frame 24 and is connected to a push plate 23. The top of the push plate 23 is in sliding contact with the bottom of the cleaning plate 21.

[0025] When the CNC machine tool is operating, the drive motor 4, blower fan 8, and heating screen frame 9 operate synchronously. Simultaneously, the electric telescopic rod 22 continuously extends and retracts, driving the push plate 23 to move back and forth. Debris and coolant generated during the CNC machine tool operation first fall onto the top of the filter screen frame 27. The left and right movement of the push plate 23 pushes the debris to the right, ultimately landing on the conveyor belt 6. The coolant then passes through the filter screen frame 27 and falls into the collection hopper 26, ultimately being discharged through the external discharge pipe 25. The debris is transported by the conveyor belt 6. Once inside the drying box 3, it is dried by the hot air from the blower fan 8 and the heating screen frame 9. This dries not only the debris but also the conveyor belt 6, preventing it from adhering to the surface of the conveyor belt 6. The debris eventually falls from the conveyor belt 6 and is transported along the conveyor ramp 71 to a subsequent storage bin. Furthermore, the conveyor ramp 71 scrapes off any remaining debris from the surface of the conveyor belt 6, thereby maintaining the cleanliness of the conveyor belt 6.
