Frequency converter in the brick block molding machine have played an important role in how to -

One, the preface

although traditional red brick in flexural resistance fell slightly has the advantage, but due to the production of red brick will consume a large amount of cultivated land, countries have gradually limiting red brick manufacture and use. Grey brick, hollow brick, such as new building materials, using cement, ashes, etc as main raw materials, the national policy vigorously promoted.

block molding machine is a kind of typical brick machinery used for suppressing the ash brick tile, use a proportional collocation good raw material, after distribution, pressing become bricks, such as high pressure steam treatment process, the resulting ash brick.

in order to improve the work efficiency and product quality block molding machine, baoding founder machinery used in G series inverter used in mechanical model of 6 brick machine, received good results.

,

block brick process machine process can be divided into feeding, cloth, die.

feeding: in proportion with good raw materials via hopper loaded into the car, the car forward by rail to the brick mould start above fabrics.

fabric: the car over the brick die again and again screen, raw material filled evenly within the brick mould, usually 3 - to distribution 4 times. Fabric at the same time, the mold must be rev shock, ensure fill even and dense. Fill the car after returning.

die: car return head began to fall, at the same time, pressure head and shock vibration device, mould shock remain but need to switch mode vibration frequency, adobe in vibration compaction compaction.

after the die, head raised, exit the adobe, begin the next feeding.

the appended drawings for cars feed pressure, pressure head and brick mould lifting hydraulic equipment

3, mechanical mold design:

due to the feeding time is relatively fixed, and the fabric of time and frequency depends on the use of raw material quality and brick of the specifications of the mold, so the block molding machine work efficiency and product quality mainly depends on the effect of molding process, especially the size of the head pressure and the effect of the earthquake.

traditional mould vibration and shock pressure are realized by using hydraulic vibrating motor, although can provide a lot of pressure, but the hydraulic vibration equipment complex structure, high cost, slow and shock, a die to be about 20 s, and the mechanical vibration device has simple structure, low cost, fast and shock, a die just about 16 s ( The fastest can be reduced to 14 s) , which greatly improve the efficiency of the brick, and equipment maintenance is easier.

user USES in VFD220F43A - 2 G inverter control 7. 5 kw level 2 motor, by 1:1. 5 belt drive, drive the shock chamber respectively in the two roller rotation. Such as to set a maximum operating frequency of 55 hz frequency converter, set acceleration time for 2 s, by 1. Five times the speed of belt transmission, shock chamber of two curved roller can be obtained within 2 s nearly 5000 RPM speed, produce high-power high-frequency vibration.

test process, the mechanical mould vibration system smoothly and earthquake, the starting current is less than 60 a, shock current in 30 years or so. Lead time 2 s, stop time 1. 5 s, shaking the desired pressure.

users are very satisfied with the result of the test. Ready to the mechanical model of design of expansion to other devices.

a summary of current block molding machine equipment required by the frequency converter, want to have outstanding low frequency torque characteristics, stable quality, good price. In G series inverter originally developed for injection molding equipment, the design of its main advantage is the low frequency torque characteristic is very outstanding, low-speed loading ability, just meet the technological requirements of block machine, in the brick industry, many across the country. Another is the G series inverter development direction.

at present, the brick machine market is growing rapidly, to improve the work efficiency and product quality, the use of frequency converter mechanical mould vibration mode has began to spread across the country. As a result of the traditional manual equipment affected by the operator's experience and proficiency, difficult to guarantee the quality, the use of PLC and HMI automatic brick machine has also become the main stream of the brick machine. Integration solution in mechanical and electrical products for the user's product development and save a lot of time and cost, and timely technical support and perfect after-sale service system for the user to remove the trouble back at home. We believe that not only is the inverter, various sets of products, including PLC controller, HMI, will inevitably grow rapidly in the whole country.
