The automatic loading and unloading machine of injection molding machine is widely used in the raw material conveying industry of injection molding machine, extruder and other equipment. It has the advantages of easy installation, simple operation, strong long-distance conveying ability, stable production, reliable operation sub-branch, and auxiliary equipment to realize fully automated production. Next, I will introduce the principle of the automatic loading and unloading machine of the injection molding machine.

When there is no material in the hopper, the mechanical air switch will fall down and open the induction switch. When the switch is felt open, the relay of the main engine opens to start the motor, and the motor runs to drive the air extraction device, which starts to pass the air filter to the small hopper. Under the action of suction, the mechanical air switch closes the discharge port upward to form the small hopper vacuum.

The feed inlet has a material tube leading to the hopper, the raw materials begin to enter the small hopper, the raw materials are isolated by the filter screen and will not be sucked into the direction of the motor, when the motor set action time arrives, the mechanical air switch falls after the small hopper has no vacuum, the raw materials fall into the dryer, and the cycle ends.
