Specification

PLC INTELLIGENTCONTROL IS

PLC, or Programmable Logic Controller, is the "brain" of a brick machine. It precisely controls the operation of hydraulic systems and feeding mechanisms through preset programs, coordinating the timing of each link. It can receive sensor signals in real time, adjust parameters like pressing force and forming speed to ensure stable brick quality. With fault self-diagnosis, it facilitates quick troubleshooting, greatly improving automation and production efficiency, serving as a core control component for efficient and stable operation of brick machines.

HOPPER

The hopper, a key brick machine component above the circular belt, temporarily stores mixed raw materials. Its bottom gate controls feeding quantity/speed, cooperating with the belt to feed evenly into molds. It buffers supply fluctuations, prevents blockages, ensures stable material flow, and connects processing and forming.
 

Hydraulic Station

The hydraulic station, the brick machine's "power heart" with oil pumps, motors, etc., converts mechanical to hydraulic energy, delivering high-pressure oil to drive actions. It adjusts pressure/flow for brick types, works with PLC for sequence control, ensuring efficient, stable operation via strong power and quick response.

Heat-treated brick molds, crafted from heat-resistant alloys, endure high temperatures and thermal stress. Custom-shaped for different brick types with smooth interiors and precise dimensions, they ensure uniform heat distribution via built-in channels, preventing cracks. Durable and reusable, they're vital for producing quality bricks efficiently.
