Block forming vibration exciter based on chaotic vibration

Abstract

The invention discloses a block forming vibration exciter based on chaotic vibration. The block forming vibration exciter based on the chaotic vibration comprises a box body, and two groups of vibration excitation organizations which are completely same in structure and arranged in parallel are arranged inside the box body. Each vibration excitation organization comprises an eccentric shaft which comprises a first eccentric cylinder, a second eccentric cylinder, a third eccentric cylinder, a fourth eccentric cylinder, a fifth eccentric cylinder and a sixth eccentric cylinder, and the first eccentric cylinder, the second eccentric cylinder, the third eccentric cylinder, the fourth eccentric cylinder, the fifth eccentric cylinder and the sixth eccentric cylinder are fixedly connected into a whole. Two sides of the third eccentric cylinder and the fifth eccentric cylinder are respectively provided with rolling bearings, an eccentric rotary plate is sleeved on each rolling bearing, and the rolling bearing and the eccentric rotary plate are in interference fit with each other. The first eccentric cylinder is provided with two belt wheels, the two belt wheels are driven by a drive motor through a conveying belt to rotate, and the rotation direction of the two belt wheels are opposite to each other. The block forming vibration exciter based on the chaotic vibration is capable of effectively improving density degree of blocks, and obtaining better forming quality.

Description

technical field [0001] The invention relates to a vibrator, in particular to a chaotic vibration-based block forming vibrator. Background technique [0002] Block is a low-energy and widely-used new building masonry structure material that does not use clay as raw material and does not need to be fired into shape; High-performance block products made of waste as aggregates are of great significance to saving land, protecting the environment, utilizing resources, and saving energy. It is a major environmental protection and energy-saving new building material project that countries all over the world are actively promoting and developing. . However, due to the diversity of block raw materials and the different fixing frequencies of each material, improving the compactness of block forming has become a major problem faced by those skilled in the art. [0003] In order to produce high-performance and wide-purpose block products, it is necessary to rely on high-performance blo...

AI Technical Summary

Problems solved by technology

[0004] 1. The commonly used vibrator is a mechanical inertial vibrator. Although the structure of the vibrator is simple, the exciting force is relatively small, and the amplitude and frequency are relatively simple, resulting in low strength and poor quality of the produced blocks. , although some advanced technologies can realize the function of amplitude modulation and frequency modulation, the exciter still cannot work at two or more frequencies. Block Building Development Requirements

[0005] 2. In terms of technical control of the existing vibrators, due to limitations in design ideas, technical levels, and comprehensive manufacturing capabilities, the control methods of most vibrators are at a relatively low level, and only a few can achieve The stepless adjustment of vibration frequency, amplitude and excitation force, and the advanced technical control level requirements for instantaneous conversion of light vibration and strong vibration have restricted the rapid improvement of the technical performance and quality level of my country's block products.

[0006] 3. Due to the limitation of structural design, the existing vibrator generally has technical defects such as few driving points of the vibration source and small effective coverage area of ​​the exciting force, resulting in a small area of ​​the vibrating table of the block forming machinery and equipment, and the obtained The finished product has small density, large error and low yield
