Plastic Hopper Loders for Automactic Feeding

NAMING PRINCIPLE

OAL- xxS

① ②

① Orste Auto-Loader

② Motor Power (HP)

S: Separate Type

FEATURES

• Microprocessor for ease of use and accurate control.
• Stainless hopper receiver ensures no material contamination.
• Motor overload protector ensures long service life of motor.
• OAL-S loaders adopts stainless steel mesh thus avoids damage to the motor.
• For OAL-S series, auto dust-removing device is standardly equipped which saves labor cost for cleaning of filters and expand the lifespan of the machine.
• Complete safety protection function device, like electricity indicator, phase-reversing alarm, material shortage and motor overloading alarm.
• Both micro-switch hopper (OMH) and photo-sensor hopper (OPH) can be directly mounted on the feed port of molding machine.

FUNCTIONAL SCHEME

The control device starts the vacuum motor to take out the air in the hopper, the material valve is closed meanwhile, thus negative pressure is created. With the function of negative pressure, material in the storage tank is delivered to the hopper through material pipe. The vacuum motor stops working when the suction time comes out, the material valve is opened by material, then material falls into injection machine or other equipment.

PARAMETERS

APPLICATIONS

Two auto loaders take the task of feeding plastic materials to 4 pcs of hopper receivers which are installed at the top of a gravimetric blender. In this way, labor cost is greatly reduced and production capacity is significantly improved.

The auto loader is responsible for loading plastic resins from the plastic storage tank beside it and loading the dried plastic resins from the hopper dryer to the feed port of the injection molding machine for products production.

In this application, OAL-1S is placed beside the injection molding machine, and it is equipped with a photo-sensor hopper receiver, which is directly installed at the feed port of the injection machine. A photo-sensor hopper receiver is always applied when the plastic is hygroscopic and it is easy to absorb moisture after drying. In this way, when the dried plastic material is empty in the hopper receiver, the auto loader feed dried material from the dryer with appropriate volume.
