Main Features of QT4-20 Automatic Block Making Machine:
1. Uses Germany Siemens PLC control system.
A. Visualization screen with easy operation;
B. Is able to set up, update and amend the production perimeters, to maximize the production output;
C. Dynamic display of the system's status, automatic trouble shooting and warning notice;
D. Has automatic-locking function, avoiding mechanical accidents caused by operational mistakes;
E. Is able to troubleshoot the machinery via teleservice.
2. Uses high-dynamic proportional and directional valves, which automatically adjust the oil flow and pressure as per specific working requirements, to buffer the hydraulic cylinder when working; uses integrated high-pressure and soft oil pipes, with easy installation;
3. Uses multi-shaft rotating and compulsory feeding, which greatly improves the density and intensity of the blocks, and reduces the feeding time as well;
4. Integrated structure of vibrating and moulding platforms, which reduces the weight of the machine, and improves the vibrating efficiency;
5. Uses double-line aero vibration-proof system, which reduces the vibrating force on the mechanical parts, improves the using lifetime of the machine, and reduces the noise;
6. High-precision guide bearings are used to assure the precise movement between the tamper head and the mould;
7. Heavy-duty machine frame, which uses high-intensity steel and advanced heat treatment, is wear resistant.

Big Five Advantages Of QT Series Automatic Block Making Machine:

Our machines, with harmonic cooperation between electrical and hydraulic machines functions, guarantee a reliable and high output production of concrete products.
1. Use Germany Siemens PLC control system and Siemens Touch Screen, use Schneider and Omron relays and contactors:
A. Siemens PLC, with great adaptability, guarantees the stability and reliability of the machine;
B. Visualization touch screen, with easy operation;
C. High-quality electrical components from Schneider and Omron;
2. Use Frequency Conversional Control Technology, which controls the block making:
A. Frequency Conversion Control: guarantees the precise and parallel movement between tamper head and mould, protects the products from transfiguration; increases the production rate by improving the vibrating efficiency;
B. Frequency controlled vibration: controls the instantaneous start and stop of the motors, to protect the motor from over-heating caused by constant working;
C. Power saving: 30%;
3. Use Double high-dynamic Proportional/Directional Valves to automatically adjust the oil flow and pressure
A. Buffer the hydraulic cylinder, to protect the cylinder from damage caused by inertia;
B. Guarantee production stability;
4. 360° Multi-Shaft Rotating and Compulsory Feeding:
A. Speedy and rotating feeding, with uniform mixing, to make sure that the density and intensity of the products are guaranteed;
B. This uniform feeding is applicable for different kinds of raw materials and moulds;
5. Use heat treatment on moulds and main parts of the machines:
A. Heavy duty machine structure and wear resistant moulds;
B. The hardness reaches up to HRC 61;
C. Greatly improves the using lifetime of the machine by 50%.
