QT4 Block Making Machine
I. Brief Introduction
Hawen QT4-15 Concrete block/paver making machine, with harmonic cooperation between mechanical, electrical and hydraulic machines functions, guarantee a reliable and high output production of different concrete products.
Customer can make various types of concrete products such as hollow block,interlocking paver,curb stone ,QT4 Block Making Machine solid brick,solid block by changing the moulds.
Feature of QT4-15 Concrete block/paver making machine:
1. Use German Siemens PLC control system and Siemens Touch Screen,Automatic Block Making Machine use Schneider relays and contactors:
A. Siemens PLC, with great adaptability, guarantees the stability and reliability performance of the block making machine.
B. Visualization touch screen, Block Making Machine with easy operation;
C. High-quality electrical components from Schneider or ABB;
2. Use Frequency Conversional Control Technology, concrete block making machine china which controls the block making:
Frequency Conversion Control: guarantees the precise and parallel movement between tamper head and mould shoe, protects the products from transfiguration;increases the production rate by improving the vibrating efficiency;
3. All the production parameters can be set from touch panel,the PLC software can be upgraded or amended to maximize the production output.
4. Use Double high-dynamic Proportional/Directional Valves to automatically adjust the oil flow and pressure . Buffer the hydraulic cylinder, to protect the cylinder from damage caused by inertia;
5. Mould can be changed quickly if customer wanna make different types of products.

II. Detail introduction of QT4-15 Paver/Block making machine
(1 ) Vibration System of block making machine
Vertical vibration force driven by eccentric synchronous revolution structure makes the materials feeding and forming better.
Vibration table places on the optimizing distributed rubber springs for better vibrating and anti-vibrating and low noise.
Fixed structure let the table generate knocking during forming which can improve the density of the concrete products
(2) Solid Structure of block making machine
The integrated structure consist of feeding cart , hopper frame and rack frame. The steel of main frame is superior Q235A, featured with fine inflexibility, high strength and less error, with thickness at 8mm. All the four pillars with special tooling positioning,it is interchangeable.
(3).Hydraulic system of block making machine
The double vane pump is world famous brand “Yuken” to coordinate proportional valve,the vibration amplitude and frequency could be adjusted freely. With proportional valve, the flow and pressure of each movement could be adjusted on touch panel according to actual situation, even to set stage speed in the same movement, making machine running quickly and without impact. Pilot operated check valves installed in pressing head ensure the reliability and safety of pressing head movement. Even if the leakage caused by wear and tear, due to the locking from pilot operated check, the pressing head will not fall down when demoulding or maintenance. What is more,in the case oil pump off and button maloperation., the pressing head will not fall down.
(4) PLC Control system
The PLC controls each production procedures with Siemens touch panel & Siemens PLC, both in English and Chinese. The electrical components of the control system use well-known international brands, such as Schneider etc., to ensure the stability of the control system, and parameters of the system can be modified from the touch screen. Remote service and Internet of Things(IoT) technology in our control system allows our customer could resolve the problem in shortest time,the parameter in touch screen can be set from Mobile phone by our technician in our office in China.
(5) Feeding cart
The feeding way uses forks to swing raw materials, with the advantages of feeding quickly and high density forpaver bricks,hollow and standard blocks,the fork is easy to be replaced and easy for maintenance for feeding cart.
