Description

Apparatus for feeding materials of injection machine}

The present invention relates to a raw material injection device for an injection molding machine, and more particularly, to a raw material injection device for an injection molding machine for receiving a raw material for an injection molding machine introduced from a raw material storage unit storing the raw material for an injection molding machine and supplying a certain amount of raw material for an injection molding machine to the injection machine.

In general, a hopper loader has been widely used as a means for supplying synthetic resin pellets to an injection molding machine in an injection factory that mainly produces synthetic resin products.

That is, the normal hopper loader sucks in the synthetic resin grains contained in the storage container together with the suction air by the suction force caused by discharging the internal air with the pumping motor, and separates the suction air and the synthetic resin grains as a filter installed on the suction path inside the hopper loader. It has been installed and used to discharge intake air to the outside and supply synthetic resin pellets to the hopper installed in the injection molding machine.

In the damper bracket of the conventional hopper loader, frequent opening and closing operations of the opening and closing plates caused by repetitive raw material supply work cause loosening of the bolts fixing the opening and closing plate rods in the center of the shaft, resulting in poor contact between the limit switch cam and the limit switch. As a result of the malfunction of the limit switch, there was a problem in that transfer defects frequently occurred during the transfer of raw materials due to malfunction of the opening/closing plate.
