[0002] The dust-free feeding machine mainly realizes dust-free operation through a negative pressure dust suction system and a closed feeding device. When materials need to be fed into the production line, the operator first puts the materials into the closed feeding device, and then uses the negative pressure generated by the negative pressure dust suction system to quickly suck the dust generated during the feeding process, and separates and collects it through a filtering device, and finally discharges the clean air outdoors. In this way, the entire feeding process is completed in a closed and dust-free environment, effectively avoiding the pollution of dust to the environment and operators.

[0003] For the dust-free feeding machine, the operator needs to place the packaging bag in the feeding housing, cut open the packaging bag and lift the packaging bag to export the materials inside. This kind of work is very labor-intensive for the operator. And in order to improve the sieving speed of the materials, vibration needs to be applied to the sieve mesh. However, this vibration method makes the materials pass through the sieve mesh slowly and is not easy for the materials to be dispersed for sieving. Content of the Utility Model
