Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] Please refer to Figure 1The embodiment of the utility model provides a chip removal structure, including a vacuum generator 4 for sucking waste chips by vacuum negative pressure and a waste chip collection container 5 for collecting waste chips, and the vacuum generator 4 is connected to the waste chip collection container 5. The various components of this embodiment are described in detail below in conjunction with the drawings.

[0019] like Figure 2 and Figure 3 As shown, specifically, the vacuum generator 4 can further include a generator shell 41, a generator core 42 and a generator chip removal nozzle 43. An air cavity 44 is provided inside the generator shell 41. The air cavity 44 of the generator shell 41 is connected to an air inlet 411 arranged on one side of the generator shell 41. The generator core 42 is installed in the air cavity 44 of the generator shell 41. A core channel 421 passes through the middle part of the generator core 42 from top to bottom. The upper end of the core channel 421 is connected to the waste chip suction port arranged on the top of the generator shell 41. The lower end of the core channel 421 is provided with a core channel expansion port 422 whose aperture gradually increases from top to bottom. The generator core 42 is provided with an inclined air vent 423 connecting the air cavity 44 of the generator shell 41 and the core channel expansion port 422.

[0020] The generator chip removal nozzle 43 is installed at the bottom of the generator housing 41 and is located below the generator core 42. A chip removal nozzle channel 431 runs through the middle of the generator chip removal nozzle 43 from top to bottom. The entrance of the chip removal nozzle channel 431 is connected to the core channel expansion opening 422. The aperture of the upper end of the chip removal nozzle channel 431 gradually decreases from top to bottom. The outlet of the chip removal nozzle channel 431 is the chip removal port of the vacuum generator 4, which is connected to the interior of the waste chip collection container 5.

[0021] In this embodiment, preferably, the generator chip removal nozzle 43 can be threadedly connected to the generator housing 41 through an external thread, which facilitates the installation and disassembly of the generator chip removal nozzle 43.

[0022] like Figure 1 and Figure 2 As shown, the waste collection container 5 can be preferably configured in a square shape, and the outer wall of the waste collection container 5 can be provided with a plurality of exhaust holes 51 for connecting the inner cavity of the container with the outside, and the exhaust holes 51 are conducive to gas circulation.

[0023] like Figure 1 and Figure 2 As shown, a connecting plate 14 may be further provided between the vacuum generator 4 and the waste chip collecting container 5 , and the waste chip collecting container 5 may be connected to the connecting plate 14 via bolts 15 .

[0024] like Figure 1 and Figure 3As shown, in actual use, an air inlet connector 13 may be provided at the air inlet of the generator housing 41, so that the air inlet 411 of the generator housing 41 may be connected to various high-pressure gas sources capable of providing high-speed gas through an air pipe.

[0026] The working principle of the utility model is as follows:

[0027] During the punching process of the punching device of the cutting machine, high-speed gas will be introduced into the air inlet of the vacuum generator. After the high-speed gas enters the air cavity of the generator shell, it will flow into the chip removal nozzle channel of the generator chip removal nozzle through the vent, and finally enter the waste chip collection container and be discharged to the outside through the exhaust hole of the waste chip collection container. Based on the principle of Venturi effect, negative pressure can be formed in the core channel of the generator core and the chip removal passage of the punching device. In this way, the vacuum generator can absorb the waste chips transported from the punching device by means of vacuum negative pressure. After the waste chips enter the core channel of the generator core, they will be discharged into the waste chip collection container through the chip removal nozzle channel of the generator chip removal nozzle for collection.

[0028] In summary, the utility model has reasonable design, simpler structure, low use cost and good chip removal effect.
