When the weight of the packaging bag 100 and flour reaches the requirement for metering, the PLC 32 controls the piston rod of the hydraulic cylinder 20 to be shortened, the supporting plate 34 moves downwards, the piston rod of the bidirectional cylinder 12 is controlled to extend, the bag mouth of the packaging bag 100 is separated from the outer side face of the dust collection ring cylinder 6, then the two sliding rings 16 slide downwards along the sliding rod 14 due to the action between the bag mouth clamp 18 and the folding corner of the packaging bag 100 in the falling process of the packaging bag 100, the distance between the two sliding rings 16 is enlarged, the bag mouth of the packaging bag 100 is pulled to be straightened, the straightening effect is realized, at the moment, the servo motor 24 drives the bidirectional screw rod 24 to rotate, and the two overtime 26 fuses the bag mouth of the packaging bag 100 at.
Finally, the piston rod of the hydraulic cylinder 20 is continuously shortened, the packaging bag 100 continues to move downwards, the clamping force between the bag opening clamp 18 and the packaging bag 100 is insufficient, the packaging bag 100 slips, and the poking rod 30 overturns the sealed packaging bag 100 through the rotation of the speed reducing motor 28 and falls on the conveyor belt 4 to be transported away.
The flour packing machine is high in automation degree, the packing bag is sleeved on the dust collection ring cylinder only by staff, and then the straightening, sealing and conveying functions of the bag opening of the packing bag are realized under the action of the PLC; set up the dust absorption ring section of thick bamboo on the periphery of discharging pipe in addition to and the dust absorption fan that is connected with the dust absorption ring section of thick bamboo, can adsorb and retrieve the dust that arouses in the discharging pipe blanking process, can not adsorb the flour that falls moreover, greatly improved workshop environment, reduce the probability that the staff inhales the dust and arouse occupational disease, control the measurement of packing flour in real time through gravity sensor, the precision is higher.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
