REIT RT15A Completely Automatic Concrete Block Production Line

The automatic concrete block making machine is made by three main parts,
including base concrete feeding device, face concrete feeding device and
compacting system. For the fourth version of REIT QFT15, base concrete feeding
device and face concrete feeding device can be moved independently, in order to
adjust and fix machines easier. The cinder block machines improvement provides
more space for workers to operate, maintain and adjust machines. It can be
universally used for the manufacturing of pavers with and without face mix,
kerbstones, hollow blocks and similar elements.
Pos.1 Green Block Conveyor
It is used for transporting the pallets with green blocks to the chain elevator
orderly. It includes transferring device inside and crawl conveyor.
The transferring device inside is parallel four rod structure and is driven by
cylinder, so it works more stable.
The crawl conveyor is combined with stationary bucket and movable frame. The
moveable frame can move the pallet horizontally for one pitch in one cycle. The
movement of frame with gear and rack mechanism is driven by electric motor
controlled by frequency controller. The beginning and stopping position are
controlled by a highly sensitive switch. In the end of the movement, there are
a forced machinery limitation and protecting device for ensuring the quality of
products.
Main parameter:
Distance transferring device moves: 120mm
Driven motor: 4kw
Transport speed: 0.20—0.48m/s
Pos.2 Rotate Brush for Green Block
It is for clean of the fresh products. The body of brush is the high
strengthened whirling nylon brush, and is supported by steel frame. The height
of brush can be adjusted according to the height of products. It is driven by a
speed reducing motor and chain.
Main parameter:
Driven motor: 0.75kw
Dimension of thread: 0.4-0.5mm
Speed of whirling: 137r/min
Pos.3 Chain Elevator with 12 Layers
It is for lifting the pallet with green blocks to certain position and stores
them as designed distance and layers. When it is full, pallets with green
blocks are transferred to the curing kiln by finger car. Its frame is sectional
steel design with two lateral safety grids. Supporting angles are fixed on bush
roller chains.
The lifting and storage device is formed by the steel hooks. The chains are
working inverted synchronous which make the pallets horizontally when being
lifted or stopped. The chains in the two sides work steadily.
The synchronous speed transmission for which REIT has patent driven by an
electric motor is equipped for ensuring the chain’s lifting synchronously. The
synchronous speed transmission is equipped with auto-lock to protect from
danger when the electricity is broken off.
The high-quality proximity sensor controllers lifting height, and the
combination of beam sensor with proximity sensor controllers the equipment
working and safety protection with double protecting device.

Main parameter:
Driven Motor: 11kw Travel speed: 0.1m/s
Stages no.: 12 Pallets per stage: 2
Stage distance :400mm
