Main Features of QT12-15F Concrete Block Making Machine

  • Base Frame

QT12-15F concrete block making machine has a heavy machine frame, with 200*200mm with 10mm thickness, the frame is made of high-intensity steel and goes through heat treatment, the total frame weight is 15.5 tons, hence it is absolutely worn resistant.

  • Feeding and Vibration System

Since the QT12-15F automatic block making machine uses multi-shaft rotating and compulsory feeding. It greatly improves the density and intensity of the blocks, also reduces the feeding and molding time.

In addition, low-frequency vibration in feeding materials, high-frequency vibration in molding. It offers the optimal structure of vibrating shafts, hence it assures the vibration is distributed uniformly in the range of the vibrating table. So it improves the uniformity and stability of blocks, produces better quality blocks than before when using the same ratio of raw material, and reduces the noise greatly.

  • Germany Siemens PLC Control System

QT12-15F block machine uses Germany Siemens PLC control system and Siemens Touch Screen.

Combine with the fault diagnosis system, it offers a dynamic display of the system's status, automatic troubleshooting, and a warning notice.

  • Frequency Conversion Technology

Since soft start function control has reduced the motor starting current, it protects the motor and extends its service life. Because the main vibration adopts low-frequency standby, high-frequency operation, so it improves the speed of operation. And it also reduces mechanical accessory and motor damage.

Most of all, the frequency converter saving about 30%-40% power than the traditional converter.

  • Mold

The mold frame is made with inlaid structure, and the mold is processed via the procedures of carburizing, nitriding, and quenching. So its service life can be up to 120,000 times production.

New Updating Improvements after the year 2017

On both sides of the mold, we add 3 aseismic bags for each side. They can reduce the impact force, protect the mold and oil cylinder in the molding process greatly.

Add 2pcs of guiding shaft and one adjusting wheel on each side, so it is easy and faster to adjust the material feeder height.

Regarding the material feeding system, a bigger and solid swing feeding arm replaced the hollow one, two motors changed to one bigger motor since one force is more concentrated and synchronous than two.
