When the feed pellet machined feed product is in the packaging operation, the dust generation of the feed is mainly in the filling bag. The operator at the time of filling the bag will first put the bag on the pocket of the automatic scale, and the bag mechanism The bag is clamped by the working action of the cylinder, and then the material is discharged into the bag to carry out the filling work. When the feed enters the package bag through the bag holder, the air will be replaced by the falling of the flour into the bag and the air inside the bag. The drop of the feed into the bag will bring in the induced air during the falling process. The effect of accumulating in the bag and the filling of the feed in the bag quickly become smaller in the space inside the bag, and finally the air pressure inside the bag is suddenly increased. It is because these relatively high pressure air fly out from the vent hole in the bag and the sewing position of the bag mouth, the feed will bring the air out of the bag, and dust and dust will be generated around the bag.
Generally, in order to prevent dust pollution caused by the operating environment when the feed is packaged, an air suction port is provided on the packaging scale. The air suction port sucks the air and sucks the dust air away; the suction device is generally disposed on the frame on the side behind the bag of the packaging scale. That is, the operator stands in front of the packing scale, and the suction device is behind the packing scale.
