[0002] To ensure factory quality, shoes are generally dusted after processing and before being boxed to prevent too much dust from adhering to the surface of the shoes.

[0003] The above-mentioned dust removal operation is currently generally carried out automatically by dust removal equipment, such as a dust removal device for shoemaking disclosed in the China Patent Library (application number: 201610974852.X), which includes a conveyor belt, a dust removal brush, a positive pressure fan and a negative pressure fan, a blowing port and a suction port. Leather is transported on the conveyor belt, the dust removal brush is located on the upper and lower sides of the leather, the blowing port is connected to the positive pressure fan, the suction port is connected to the negative pressure fan, the blowing port and the suction port are respectively located on the left and right sides of the leather; the suction port is connected to the suction hood, and the suction hood is connected to the suction pipe. The suction hood has a large diameter at the suction port, and a small diameter at the suction pipe.

[0004] When the above equipment is applied to dust removal of finished shoes, since different shoes have different heights and widths, and the dust removal brushes and air suction hoods in the above equipment are fixed, it is difficult to adjust for shoes of different specifications, which affects the dust removal effect. Utility Model Content
