[0036] Working principle:

[0037] Step one, form a passage among the air diffuser cover 102, the sleeve 111 and the dust collection box 31, the suction force generated by the fan 9 can make the air in the production workshop enter from the dust collection cover 7, when the air reaches the filter bag 37, the filter bag 37 filters the air, preventing dust particles from entering the filter bag 37, the purified air passes through the sleeve 111 to reach the air diffuser cover 102, the air diffuser cover 102 can make the gas disperse through the activated carbon adsorption plate 104, the activated carbon adsorption plate 104 adsorbs harmful substances in the air, and finally the air is discharged from the air outlet of the fan 9, realizing the air dust removal in the production workshop;

[0038] Step two, when the need to remove dust from the raw material packaging entering the production workshop, close the valve 6 of the dust collector 7, open the valve 6 of the dust collection mechanism 8, take the handle 81 from the hanger 4, when the curved barrel packaging is removed, hold the handle 81 and move the suction cover 82 along the packaging barrel, the gas enters the suction cover 82 from the air inlet groove 83, and the gas flow carries away the dust on the surface of the packaging barrel.

The baffle 851 moves along the surface of the packaging box to achieve dust removal of the box packaging. Therefore, the dust on the raw material packaging entering the production workshop can be removed.

[0039] Step three, when the need to monitor the air permeability of the filter bag 37, as the dust on the inner wall of the filter bag 37 gradually increases, the air permeability decreases. Once the air permeability is not consistent with the air volume of the fan 9, the suction force on the piston 114 increases, the piston 114 moves right along the inner wall of the box body 112, the pull rod 116 moves right with the piston 114, the cam 1110 rotates clockwise under the transmission of the rack 117 and the gear 1111, when the cam 1110 tilts to the right, the piston 114 continues to move right under the double power of the cam 1110 and the fan 9, until the contact 1114 contacts the limiting rod 1113, forming a closed loop with the controller 33, the flow channel 115 is connected with the air inlet hole 113, allowing air to flow along the flow channel 115 to the fan 9.
