For those skilled in the art, the specific meaning of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0047] Please refer to Figure 1 With Figure 2 , the first aspect of the present application provides a dust removal mechanism for pressing knife, comprising: a brush plate 10. The bottom of the brush plate 10 is provided with a brush 11; The brush plate 10 is provided with air holes 12.

[0048] In the existing system provided with the dust removal mechanism for pressing knife, the suction and blowing mechanism and the brush are generally arranged separately. In the present scheme, the brush 11 and the air hole 12 are integrated on the brush plate 10, so that the airflow dust removal and the scraping dust removal can be carried out synchronously, which improves the dust removal effect of the pressing knife and helps to compact the overall device structure.

[0049] In the present embodiment, the air hole 12 can blow air or suck air.

[0050] Taking the air blowing dust removal of the air hole 12 as an example, when the brush 11 scrapes the surface of the pressing knife, the air hole 12 can blow the dust brushed up by the brush 11, avoiding the part of dust from falling on the surface of the pressing knife again, thereby improving the dust removal effect of the brush plate 10 on the pressing knife.

[0051] Taking the air blowing dust removal of the air hole 12 as an example, when the brush 11 scrapes the surface of the pressing knife, the air hole 12 can blow the dust brushed up by the brush 11, avoiding the part of dust from falling on the surface of the pressing knife again, thereby improving the dust removal effect of the brush plate 10 on the pressing knife.

[0052] In a more specific embodiment, please refer to Figure 3The brush plate 10 is provided with an air pipe 13; the air hole 12 is communicated with the air pipe 13. Specifically, the air pipe 13 can be communicated with the inside of the brush plate 10, and an auxiliary pipe 14 is arranged in the inside of the brush plate 10; the auxiliary pipe 14 is communicated with the air pipe 13 and the air hole 12.

[0053] In the embodiment in which the air hole 12 blows air to remove dust, the air pipe 13 is a blowing pipe; and an air suction member can be arranged outside the brush plate 10; the air suction member can be, for example, an air suction pipe. The air suction member is arranged on the pressing platform 20 as shown in the drawings, and faces the brush plate 10, and is used to suck away the dust blown by the air pipe 13. Figure 5

[0055] In one embodiment provided in the present application, the air hole 12 faces the side of the brush plate 10. When the air hole 12 blows or sucks air from the side, a lateral air flow can be formed, so that the dust swept by the hair brush 11 can be carried away from the surface of the pressing knife by the air flow in time, effectively preventing the dust from falling on the pressing knife again, avoiding secondary pollution, and further ensuring the cleaning effect on the pressing knife.

[0056] At the same time, the hair brush 11 can be connected to the brush plate 10 in a detachable manner. The air hole 12 arranged on the side is helpful for the maintenance of the hair brush 11 by the worker.

[0057] In one embodiment, the brush plate 10 is provided with a brush groove 15; the hair brush 11 is arranged in the brush groove 15; the brush groove 15 is communicated with the air pipe 13, so that the air hole 12 can directly blow or suck air to the hair brush 11, so that the air hole 12 can remove the dust adhered to the hair brush 11, and further improve the dust removal effect.
