The mounting bracket 46 includes a mounting plate 462, a support plate 463 and a limiting groove 461 provided on the support plate 463, the mounting plate 462 is vertically welded between two posts 5 near one end of the dust blocking curtain 42, the support plate 463 is vertically welded in the middle of the mounting plate 462 departing from one side of the discharge pipe 2, and the limiting groove 461 is provided on the support plate 463 and is open at one end far away from the discharge pipe 2 for mounting the dust collecting box 44.

Referring to fig. 3, the dust box 44 is formed in a hollow cylindrical shape, and the dust box 44 is fixed in the retaining groove 461 in a clamping manner, so that the possibility of rolling of the dust box 44 can be reduced. The dust box 44 includes a box body 441, a box cover 442, and a filter membrane 443 disposed in the box cover 442. The box body 441 is open at one end close to the box cover 442, the box cover 442 is open at one end close to the box body 441, and the open end of the box cover 442 is in threaded connection with the open end of the box body 441 so as to take out and treat the powder concentrated in the dust collection box 44.

The filter membrane 443 is clamped and fixed in the box cover 442, the box cover 442 is closed by the side wall of the end, away from the box body 441, of the box cover 442, the aperture of the filter membrane 443 is smaller than that of powder, the end, away from the box body 441, of the box cover 442 is in threaded connection with the air inlet pipe of the air pump 45, the air inlet pipe of the air pump 45 is communicated with the inner cavity of the dust collection box 44, the air pump 45 is fixed on the mounting plate 462 through screws and used for pumping the dust collection box 44 into a negative pressure state, the filter membrane 443 can block raised dust in the dust collection box 44.

The dust collection box 44 is far away from one end of the air pump 45 and is connected with the dust collection pipe 43, the dust collection pipe 43 comprises a guide pipe 431 and a connecting pipe 432, the connecting pipe 432 is a flexible rubber pipe, one end of the connecting pipe 432 in the length direction is connected with one end of the box body 441, which is far away from the mounting frame 46, the height of the connecting pipe 432 can be increased, and the possibility that powder in the dust collection box 44 flows backwards into the connecting pipe 432 is reduced.

One end, far away from the dust collection box 44, of the connecting pipe 432 is in threaded connection with the guide pipe 431, the guide pipe 431 is a hard threaded pipe, a through threaded hole is formed in the main board 411, one end, far away from the connecting pipe 432, of the guide pipe 431 is arranged in the threaded hole of the main board 411 in a penetrating mode and in threaded connection with the main board 411, so that a channel formed by the guide pipe 431, the material guide plate 3 and the cover plate 41 is communicated, and therefore dust in the channel formed by the material guide plate 3 and the cover plate 41 is sucked into the dust collection box 44 for centralized.

The guide pipe 431 forms an acute angle with the moving path of the powder on the material guide plate 3, so that the possibility that the powder on the material guide plate 3 enters the dust collection box 44 can be reduced. The connection pipe 432 has a length greater than a distance between the dust box 44 and the guide pipe 431 so that the connection pipe 432 can be wound to facilitate the removal and installation of the dust box 44.
