[0030] Working principle: when in use, first the second drive motor 11 drives the conveying roller 22 to rotate, and the conveying roller 22 drives the externally sleeved dust cloth 21 to move, and at the same time the fan 23 sends air downward, and while the dust cloth 21 moves, the mounting roller 25 rotates together under the action of the double-sided adhesive tape 24 attached to the external dust cloth 21, and then the flame retardant nylon to be mixed is put into the mixing box 2 through the hopper 1, and the flame retardant nylon raw material will fall on the dust cloth 21, and the fan 23 will absorb the dust in the raw material through the negative pressure of the wind and the filtration of the dust cloth 21, and the dust-removed flame retardant nylon will fall on the sealing plate, and at the same time the double-sided adhesive tape 24 is attached to the outside of the dust cloth 21 to clean the dust adhering to the dust cloth 21, thereby ensuring the air permeability and filtration effect of the dust cloth 21, and then the mixing motor 12 drives the driving shaft 14 to rotate, and the driving shaft 14 drives the mixing rod 13 to rotate, The raw materials in the mixing box 2 are mixed and stirred.

The cam 27 will drive the guide rod 31 to move axially back and forth through the push plate 29 and the first spring 30. The guide rod 31 drives the support block 6 to move back and forth, thereby driving the entire mixing box 2 to move back and forth, so that the flame-retardant nylon in the mixing box 2 is mixed more evenly during stirring. When the flame-retardant nylon in the mixing box 2 is mixed, the second lifting motor drives the sealing block 15 to descend through the push rod, so that the top surface of the sealing block 15 is flush with the lower edge of the discharge port 3, and then the first lifting motor 5 drives the movable rod 4 to descend. The mixing box 2 is tilted toward the discharge port 3 under the action of the first U-shaped member and the second U-shaped member, so that the flame-retardant nylon mixed in the mixing box 2 is automatically discharged from the discharge port 3, and there is no need for workers to use tools to take out the flame-retardant nylon mixed in the mixing box 2;

[0031] When too much dust is stuck to the double-sided tape 24 and it loses its stickiness, just pull the support plate 19 outward to compress the second spring 17, separate the mounting roller 25 and the old double-sided tape 24 from the dust-removing cloth 21, and move them out of the through slot 20, then tear off the old double-sided tape 24 from the mounting roller 25, and then stick a new double-sided tape 24, then release the support plate 19, and reset the second spring 17 in the compressed state. At the same time, the second spring 17 resets and drives the mounting roller 25 with the new double-sided tape 24 stuck to it to move toward the through slot 20, so that the double-sided tape 24 is again attached to the outside of the dust-removing cloth 21, thereby ensuring the effect of the double-sided tape 24 in cleaning the dust accumulated on the outside of the dust-removing cloth 21.
