BIG FIVE ADVANTAGES OF QGM AUTOMATIC BLOCK MAKING MACHINES Our machines, with harmonic cooperation between mechanical, 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. 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 52-58; C. Greatly improves the using lifetime of the machine by 50% Main Features: 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 systems 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
