QT6-15 Automatic Block Making Machine
QT6-15 (6 stands for the production quantity is 6 blocks “400x200x200mm” per mould, 15 stands for the cycle time is 15 seconds) has the production output of 8640-11520 blocks (400x200x200mm) or 120-160 cubic meters for one day (8 working hours). As the moulds are changeable, it’s able to produce different types of blocks/bricks.1)Uses Germany Siemens PLC control system and Siemens Touch Screen.

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;

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 52;
C.Greatly improves the using lifetime of the machine by 50%.

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.
