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.
