This process will not tear the big bag from the oblique hook;

Epoxy resin granules fall from the annular gap between the blanking tray and the round table tube on the convex circular plate, break up and fall into the silo, and can evenly distribute the material in the silo, and wait for the discharge to be completed. Finally, the electric hoist heavy machine quickly Lift the ton bag and the oblique hook to separate the ton bag from the automatic opening mechanism. At the moment of tearing apart, the spring rebounds quickly, and the spring stretches back and forth at a small frequency, so that the epoxy resin particles on the blanking tray It is shaken off and falls into the silo to avoid material loss, and then the spring stops moving, and all the cone tips come together to return to the initial state, and the next unpacking work can be repeated. Compared with the prior art, the present invention utilizes material The gravity of the blanking itself drives a series of actions. It is practical and efficient to use the electric hoist to quickly and frequently lift and lower the epoxy resin particles remaining in the ton bag into the silo. Compared with direct beating, beating the particles Collide with each other back and forth and take a long time, but the ingenious design of the present invention uses the electric hoist to drive the ton bag to shake up and down, the particles can pass through the ton bag quickly, and clean up the residual material in the ton bag in a faster time. It does not need to be attached to mechanical components with complex structures to achieve clean, fast, convenient and no material loss in the whole process. At the same time, the production cost is also reduced, achieving the purpose of energy saving, emission reduction and safe production for enterprises. It is suitable for Comprehensive promotion and application.
