How does hopper vacuum loader work?
2023-12-12 Page view：
The working principle of a hopper loader involves the automatic loading of raw materials, typically used in plastic processing or molding industries, into processing equipment like
injection molding machines or extruders. Here's a breakdown of its working principle:
Material Collection: Raw materials, often plastic resin or pellets, are stored in a designated container or hopper connected to the hopper loader.
Vacuum Creation: The hopper loader uses a vacuum pump or blower to create a vacuum or negative pressure within its system.
Material Conveyance: When the processing machine requires more material, the hopper loader's vacuum draws the raw materials from the container or hopper through a hose or pipeline.
Transportation: The materials travel through the hose or pipeline, driven by the vacuum pressure created by the hopper loader.
Loading into Processing Equipment: The materials are conveyed directly into the hopper of the processing machine, such as an injection molding machine. This automatic loading
process ensures a continuous supply of raw materials to the processing equipment.
Controlled Supply: Sensors or switches within the processing equipment or the hopper loader monitor material levels. When the material reaches a certain level, the hopper loader
can stop conveying material until more is needed, ensuring proper control of material supply.
The hopper loader's primary function is to automate the material loading process, reducing the need for manual intervention and enabling continuous production by providing a steady
supply of raw materials to the processing machinery.
