[0013] The utility model is described in detail below in conjunction with specific implementation methods:

[0014] like Figures 1 to 3 The negative pressure filtering device for deburring the housing of an advertising machine shown in the figure comprises a grinder body 1, a negative pressure channel 2, a central axis 3, a cross-shaped filter frame 4, an aggregate extraction 41, a dust filter frame 6, a first flange 21 and a negative pressure air duct 22, wherein the grinder body 1 is provided with a grinding wheel 5, the negative pressure channel 2 is fixedly mounted on the grinder body 1, the lower half of the grinding wheel 5 is placed in the negative pressure channel 2, the cross section of the negative pressure channel 2 is arranged to be a square structure, the front and rear ends of the central axis 3 are rotatably sealed on the front and rear walls of the negative pressure channel 2, the center of the cross-shaped filter frame 4 is fixedly sleeved and mounted on the central axis 3, and the four brackets of the cross-shaped filter frame 4 are all fixed A large particle debris filter is installed, and sealing strips are fixedly installed on the outer sides of the front, rear, left and right frames of the cross-shaped filter frame 4, and the sealing strips are tightly attached to the inner wall of the negative pressure channel 2. The aggregate drawer 41 is installed in the negative pressure channel 2 by bolt sealing and plugging, and the aggregate drawer 41 has a top opening. The first flange 21 is fixedly installed at the bottom of the negative pressure channel 2, and a second flange is provided on the top of the negative pressure air duct 22. The second flange is screwed and sealed and fixed on the first flange 21. The dust filter frame 6 is pressed, fixed and sealed between the first flange 21 and the second flange, and a dust filter is fixedly installed on the dust filter frame 6.

[0015] The top of the negative pressure channel 2 is set as a bucket-shaped structure, and the lower half of the grinding wheel 5 is placed in the bucket-shaped structure. The top structure of the negative pressure channel 2 is enlarged and set to a bucket-shaped structure, which can be the gathering area of ​​the negative pressure channel 2, and prevent large particles of debris or plastic powder generated during the deburring and grinding process from drifting to the outside of the negative pressure channel 2.
