Main Features of Big bag unloader:

1. The unloader simple and reasonable structure, convenient operation and use.

2. According to the on-site facilities, and demand, a variety of specifications is optional.

3. discharge valve tighten agencies using elastic steel belt type, firm mouth convenient and reliable.

4. pressure bag institutions guarantee unloading process, without dust leakage.

5. The flap at the bottom of the flap type device and central pat device can better guarantee the discharge smoothly, prevent material stranded.

6. configuration, dust control interface, and users to connect dust removal system, dust collection, protect the environment clean.

working principle of big bag unloader:

The bag is lifted by the electric hoist, the bag rope of the bag is hung on the steel bracket, the hoist is manually controlled to lift and walk, and it runs along the walking guide rail to the top of the unloading area. The bag is placed on the tray of the bracket, so that the big bag is in the unloading position.

Then manually open the discharge valve door operation, manual pull discharge outlet bags into the discharge valve of the mouth, is bag button, discharge valve beam fasten the cylinder contents, and then manually to the discharging mouth of the sack down from the discharge position, cover the discharge outlet seal in the outer edge of the discharge tube, pneumatic control switch press bag institutions, resulting in a sealing flange, and the press in the discharging pipe tube, sealing discharge channel, to prevent leakage in the process of discharging dust, then the artificial solution bags, shut the door operation.

Manually open the valve on the ventilation and dust removal pipe connected to the discharge port seal box.

At this point, the discharge preparation process is over.

Unloading process: manually open the tightening mechanism in the unloading valve, the unloading port of the packaging bag is opened, the material begins unloading along the pipe chute under the action of gravity, and enters the unloading process.

In the unloading process, according to the process requirements of the whole system, the unloading valve bundle mechanism can be automatically or manually controlled to control the unloading process.

When the silo of the user's screw belt mixer is filled with materials, press the button of the big bag tightening mechanism to tighten the unloading port of the big bag and stop feeding to the mixer.

In the unloading process, in order to make the material flow smoothly in the packaging bag and pipe chute, add the auxiliary action such as bag slapping mechanism, automatic or manual operation.

The action of slapping and punching bag can also be controlled by PLC, regularly slapping and punching bag. The action sequence is to beat the middle part of the big bag first, and then the bottom of the big bag.

After unloading, open the operation door of the discharge valve. After manually tying the bag, the tightening mechanism loosens, the bag pressing mechanism rises, and the electric hoist is manually operated to lift out the empty bag.
