3M Saudi factory large bag unloading, weighing batching scale

At the end of 2016, 3M Shanghai Cao He jing factory started the relocation work. Related installations relocated to the 3M Saudi factory. One of our company in October 2017 for the 3M Saudi factory produced a complete set of large bag unloadingWeighing batching scaleSystem, the system will be operational in March 2018.

The system includes large bag unloading system, tapping device, weighing system, dust collection system and support maintenance platform. The whole system operates independently, controlled by PLC and touch screen operation.

The full material bag is transported through the forklift, and the electric hoist is elevated to the high position, and is moved along the guide rail to the discharging location. Manual will be a large bag under the mouth to expand and set in the bag barrel wall, after the pneumatic clamping, unlock the material mouth Zahan, the material through the entrainment into the bottom has started the screw conveyor, the screw conveyor rapid rotation of the material into the weighing hopper, When the weight of the material in the hopper is close to the preset weight, the spiral is automatically adjusted to slow, slowly feeding, when the final material weight is reached and the pneumatic butterfly valve is closed to prevent the material from continuing to fall. Adjust the screw speed and feed stop ahead of time to ensure weighing accuracy.

The big bag hangs in the electric hoist and the bottom and the flap contact, the flap cylinder automatic expansion, the drive flap plate to the big bag bottom carries on the flap, in order to break up the material agglomeration, helps the material whereabouts, and guarantees the big bag the material residue quantity achieves the smallest.

Before weighing begins, installed in the maintenance platform side of the dust collector in advance automatic start, through the weighing hopper above the cover of the annular dust suction, the hopper dust suction, adjust the appropriate suction negative pressure, to achieve the dust is not leak without affecting the weighing accuracy.

The system has been shipped to the Saudi factory, in the recent installation and commissioning.

At the same time, we also modified the project for the spiral conveyor, such as a series of products.
