Body

The machine body is made of strong, hollow, thick, rectangle section steel using special welding technology, resulting in high durability. There are four chrome plated guiding columns fixed on the body of the machine, which are used for guiding the up mould and down mould. Driven by hydraulic cylinders, the moulds move up and down along the guiding columns. The utilization of gear and pinion rack reinforcing synchronizing device ensures rapid, accurate movement of mould. The down mould runs steadily, without being shocked while starting and stopping. The mould support and guiding columns use lengthened guiding sleeves, contributing to high guiding precision and long service life. The movement of the whole body, from vibrating position to demoulding position, is driven and adjusted by proportion valve and double buffer hydraulic cylinder.

Feeding Device of Concrete Block Making Machine

The feeding device consists of hopper and filler box. The concrete hopper has a capacity of 1000L, and its outlet is driven by hydraulic cylinder. The time, frequency and degree for opening and closing the outlet can be adjusted by control system. The hopper is equipped with a level indicator which gives signals for filling or stopping the concrete. The filler box is driven by double buffer cylinders, and the synchronized rod can take movement of two sides. This ensures steady, shock-free feeding movement, reduced abrasion to parts and no leakage of materials. Due to its unique structure and compound movement, the rotary feeding mechanism in the filler box can make the filling process fast and wet concrete in the mould well-distributed, thus assuring consistent product quality.

Compacting System of Concrete Block Making Machine

The vibrating table and the up mould both are fitted with vibrators, forming a compacting system featuring “down mould main vibrating up mould vibrating up mould pressing”. Concrete filling process and compacting process are respectively completed through pre-vibrating and main vibrating. Pre-vibrating during filling is time controlled. When the filling process is completed, the up mould presses downward and main vibrating starts. The compacting method can not only satisfy the production of common concrete products, but also ensure smooth compacting and demoulding operations when making fly ash concrete products.
Four-shaft synchronized vibrator (REIT patent) is installed under vibrating table and driven by two electric motors. The special synchronous device ensures the vibrating table generates vertical oscillations. The amplitude and frequency of vibrators can be adjusted according to the specific raw material and blocks.
Compulsory limit support for pallet is designed. The pallet can impact the limit support while moving downwards, and therefore, the vibrating force is greatly increased, forming vibrating pressure to blocks. This can effectively reduce fatigue damage to isolation pad of vibrating table. In addition, there is an efficient vibration isolation system between the vibrating system and machine body, which keepsvibrating energy that the foundation and frame receive at a minimum, thus making foundation building and installing operations easier.

Hydraulic DriveUnit of Concrete Block Making Machine

The hydraulic drive unit is made using hydraulic elements from famous suppliers. It is designed to supply power to main devices of the block machine. All of the hydraulic elements are integrated in the form of hydraulic station, and all of the control valves are installed in a control module. The hydraulic station is equipped with radiator and return filter, which helps ensure operational reliability and long service life of the hydraulic system. It is linked with block machine by high pressure soft hose. All of the hydraulic pipes are put on the block machine with hard pipes except cylinder uses soft pipe. The hydraulic cylinder utilizes built-in buffer unit, and the hydraulic pipeline adopts balance loop, contributing to the steady, rapid and smooth operation of equipment. 

Auto Control System of Concrete Block Making Machine

The auto control system consists of control panel, control cables and a variety of sensors. The PLC control system features user friendly interface and has data input and output, diagram display functions, enabling the operator to operate it fast and easily. Manual operation and automatic operation are both available. Through the touch screen the operator can set, revise parameters and timely know the operating conditions of the whole production line. The PLC is a Siemens product. Other electronic elements are from world renowned suppliers such as Omron, ABB.

Pos. 2: Up-down Whirling Table

The support frame with compacting system will automatically move to the demoulding position after performing the compacting operations. The up-down whirling table can assist the main machine in completing demoulding process as well as stacking of green blocks. The whirling table runs steadily and reliably as its elevating and descending apply scissor structure and its turning applies seat ring bearing structure. The utilization of digital encoder unit assures the precision of positioning and thus protects products during demoulding and stacking processes.

Pos. 3: Delivery Roller Conveyor

The delivery roller conveyor is used for moving the pallets with stacked products from theup-down whirling table, which makes it convenient for the forklift to transport stacked products to the curing place.
