Tons of bags open (reverse) bag station


Product description

The ton bag unpacking machine can handle the unpacking and unloading operations of large bagged powdery granular material bags, and is widely used in food, medicine, chemical and other industries.


Working principle

The ton bag unpacking machine is used to realize the unloading function of the bagged bulk materials, and is semi-automatic operation. The bag is lifted by the electric hoist. The bag rope of the bag is hung on the steel bracket. The hoist is manually operated to control the hoist to lift and walk. It runs along the running rail to the top of the discharge area, and the bag is placed on the bracket tray to make the bag. In the unloading position. Then manually open the discharge valve operation door, manually pull the discharge port of the bag into the system of the discharge valve, press the tie button, the discharge valve tightens the cylinder to lock the bag mouth, and then manually the large bag The discharge port is pulled down from the discharge position, and is placed outside the discharge pipe in the discharge box of the discharge port, and the pneumatic control switch of the pressure bag mechanism is pressed to lower the sealing flange and press the pipe end of the discharge pipe. Seal the discharge channel to prevent dust leakage during the unloading process, then manually unpack the bag, and finally, close the operation door. Manually open the valve on the ventilation dust removal pipe connected to the discharge port seal box. At this point, the unloading preparation process ends.



1. The bag opening station has a simple structure and is easy to operate;

2, the tapping equipment can ensure that the material smoothly goes from the big bag to the next step;

3. The crusher breaks up the agglomerate during the bag opening process to ensure the smooth progress of the next step;

4. The magnetic separator can remove foreign matter in the large bag;

5. Fully automated operation to improve production efficiency and reduce labor intensity;

6. Closed bag opening to prevent dust flying, improve working environment and reduce production cost;

7. Integrated design of bag opening, tapping, crushing and magnetic separation, compact structure and convenient operation;

8, can provide pneumatic or electric control mode to achieve remote monitoring;

9. Applicable working conditions: large bag packaging materials with poor fluidity, easy moisture absorption, and agglomerated materials;

10. Applicable industries: All industries involving powders such as pharmaceuticals, food, and chemicals.


Field of application

Tons bag unpacking equipment is widely used in petroleum, chemical, chemical fiber, dye, medicine, food, electronics, paper, building materials, electric power, environmental protection, metallurgy and other production areas, can be used for any material bags (such as plastics and plastic additives, Mixing agent, sewage treatment clarifier, dry powder such as cement, granular material, powder mixture, sheet material) into the automatic unpacking and unloading operation.
