国外空心砌块成型机发展较早,种类很多,可以生产不同品种,不同规格的砌块。这些成型机大致分为移动式和固定式两种类型。成型方式,全采用加压振动成型。振动器不采用附着式振动器,而用电机经三角皮带传动,带动偏心块起振。采用这种柔性传动的型式可以减少电机的振动,延长电机的使用寿命。目前砌块的生产,不少国家已建成生产线,实现了自动化和半自动化。鉴于各国生产的砌块成型机种类较多,自动化程度亦高。在发展我国砌块成型机的生产中,下述几种成型机可供参考。
The early development of foreign hollow block machine has many types and it can produce blocks of different varieties and different specifications. These molding machines are roughly divided into two types, mobile and fixed. Molding method, all using pressurized vibration molding. The vibrator does not use an attached vibrator, but uses a motor driven by a V-belt to drive the eccentric block to vibrate. Using this type of flexible transmission can reduce motor vibration and extend the life of the motor. At present, the production of blocks, many countries have built production lines, to achieve automation and semi-automation. In view of the large number of types of block machines produced in various countries, the degree of automation is also high. In the development of the production of block forming machines in China, the following types of molding machines are available for reference.
