Automatic powerful vibration concrete block moulding machine

Abstract

The invention discloses an automatic powerful vibration concrete block moulding machine. The frame of the machine is welded into a frame structure, a powerful vibration excitation mechanism is arranged on a frame base, a support plate transfer mechanism is arranged upon a vibrating table, and a feeding mechanism and a compacting and moulding mechanism are arranged on a guide upright post. The machine adopts the drive control technical measures that after a frequency adjustment vibration motor is sequentially connected with a synchromesh gear case, a power transmission shaft and a vibration exciter, the vibrating table is driven to vibrate, the vibration motor is adjusted by a frequency automatic adjustment program control device to change the rotating speed of a vibration exciter and the like, and the machine solves the technical problems of four-axis synchronous efficient powerful excitation, stepless adjustment of vibration frequency, vibration amplitude, excitation force and the like; and the flexible connection parts such as a coupler, a vibration reduction block, an air spring and the like made by hard rubber fiber are adopted, so a multistage combined vibration isolation and vibration reduction measure is formed, and a damage impact force produced by vibration can be reduced. The machine is used for producing the concrete block, and has the characteristics of high degree of automation, large excitation force covering area, fast moulding period, high product strength grade and the like.

Description

technical field [0001] The present invention relates to a kind of mechanical equipment for building materials, specifically a kind of strong periodic vibration as the power source, which is used to compact the concrete mixture filled in the cavity of the mold with standard specifications into concrete block products. Vibrating concrete block automatic forming machine. Background technique [0002] Concrete block is a low-energy, wide-purpose new building masonry structure material that does not use clay as raw material and does not need to be fired into shape; High-performance concrete block products made of solid waste as aggregates are of great significance to protecting the environment, saving land, utilizing resources, and saving energy. material item. [0003] The production and application of concrete blocks has a history of more than 100 years abroad, especially in industrialized countries such as Germany, Italy, Japan, and the United States. Concrete blocks have be...

AI Technical Summary

Problems solved by technology

[0008] First, the degree of automation matching is not high, and the production efficiency is low

At present, among the concrete block forming machinery and equipment widely used in our country, there are not many models that can realize all the automatic operation and control operations in the core operation links such as plate replacement, material distribution, pressing, demoulding, and operation control; , In order to reduce the manufacturing cost of the small model, the traditional operation method of manual cloth and manual demoulding is still used, so that the molding cycle of each mold is generally more than 1min, and the production efficiency is low

[0009] Second, the vibration forming ability is not strong, and the block quality is poor

Due to the limitation of scientific and technological level and processing and manufacturing capacity, most of the concrete block forming machinery and equipment currently produced and sold in my country are based on the original brick-making machinery, which has been improved and put into production after adding a simple vibration device. Compared with western industrialized countries , there is a gap in vibration forming ability; in terms of structural layout, one machine and one axis are generally used; in the selection of vibration motor power, generally 7.5kw is selected, and the maximum does not exceed 20kw; the vibration acceleration of the mold box, generally No more than 8G; especially in terms of technical performance such as the synchronous speed of the vibration motor, the deviation of the amplitude of the mold box, and the adjustment and control of the exciting force, they are all at a low level, resulting in the production of concrete blocks in terms of strength level, appearance and molding quality. , dimensional deviation and other aspects are at a low level

[0010] The third is that the manufacturing quality is rough, the service life is not long, and the production capacity is low

At present, most of the concrete block forming machinery and equipment commonly used in my country have problems such as unreasonable structural layout and rough manufacturing quality. Quality accidents such as frame opening welding and mold box fracture often occur during use; especially Due to the limitation of structural layout, the area of ​​the vibrating table is not large. Generally, only 5 pieces can be formed per mold, and the maximum can only reach 9 pieces. The production capacity is low.
