High-compactness concrete product molding machine

Abstract

The invention discloses a high-compactness concrete product molding machine. The machine comprises a bracket I, wherein the upper end of the brake I is provided with a vacuum vibration molding device; the front end of the vacuum vibration molding device is provided with a matching quantitative feeder; the lower end of the quantitative feeder is provided with a spreading surface material distributing machine; a matching bottom material distributing device is arranged at the rear end of the spreading fabric distributing machine and on the lower side of the vacuum vibration molding device; a steel mesh automatic laying device is arranged at the front end of the bottom material distributing device and at the lower end of the spreading surface material distributing machine; the front of the steel mesh laying device is provided with a matching brick receiver. The machine has the beneficial effects that high-compactness high-strength concrete products can be produced by using a vibration compression molding principle; particularly the conventional casting process is changed, the natural stone imitation concrete products are mechanically produced on a large scale, and extremely high economic benefit and social benefit are realized; the products are more compact, higher in strength, delicate, bright and clean in appearance and can be further deep-processed into decorative concrete products.

Description

Technical field [0001] The invention relates to a concrete product forming machine, in particular to a high-density concrete product forming machine. Background technique [0002] At present, the concrete product molding machines that adopt vibration molding in the world all use dry hard concrete, which is quickly demolded after pressurized vibration molding, and then cured to become a product. The advantages of this forming principle are high efficiency and conducive to large-scale industrial production; but there are also the following shortcomings: [0003] (1) Due to the use of dry hard concrete, the hydration reaction of the cement is insufficient, and the strength of the product is lower than that of wet molding; [0004] (2) Due to the low total water content of dry hard concrete, it is difficult to mix evenly, resulting in large deviations in product strength; [0005] (3) Due to the poor fluidity of dry concrete, the internal compactness of the product is insufficient, and ...

AI Technical Summary

Problems solved by technology

[0003] (1) Due to the use of dry hard concrete, the hydration reaction of cement is insufficient, and the product strength is lower than that of wet forming;

[0004] (2) Due to the low total water content of dry hard concrete, it is difficult to mix evenly, resulting in large deviations in product strength;

[0005] (3) Due to the poor fluidity of dry hard concrete, the internal compactness of the product is insufficient, and there are many local micropores, which cannot meet the quality requirements of imitation natural stone and refined decorative materials;

[0008] (1) The efficiency is low, and there are many manual operation links, making it difficult to realize large-scale industrial production;

[0009] (2) A large number of molds (at least 100 sets or more) are required for each type of product, which increases production investment and requires a larger work site. Moreover, such molds have a short service life and are easily deformed, making it difficult to reuse them for a long time , resulting in higher overall cost;

[0010] (3) Manual or semi-mechanized operations are basically carried out in the steps of laying materials, demoulding, and stacking, with many human factors and errors, unstable product quality, and poor consistency
