Device and process for forming double-layer brick

Abstract

The invention provides a device for forming a double-layer brick. The device comprises a conveying mechanism and a blanking mechanism. The conveying mechanism comprises a conveying belt, a first vibrating mechanism and a second vibrating mechanism. The conveying belt comprises a first steady conveying section, a first vibrating conveying section, a second steady conveying section, a second vibrating conveying section and a third steady conveying section. The blanking mechanism comprises a brick surface material blanking mechanism and a brick backing material blanking mechanism. When the device for forming the double-layer brick is in use, after a pulpy brick surface material is vibrated in a die to be evenly spread and is naturally coagulated to the setting degree and not completely coagulated, a pulpy brick backing material is poured on an upper layer and is vibrated to be evenly spread, contact surfaces of both the brick backing material and the brick surface material are in full combination, and the brick backing material and the brick surface material are simultaneously naturally coagulated to be an integrated body. The device for forming the double-layer brick is novel and reasonable in structure, forming efficiency and integration of the double-layer brick are high, the brick surface and a brick base are not subject to delamination easily, and the strength is high. The invention further provides a double-layer brick forming process matched with the device, the whole process is clear and simple, and forming efficiency is high.

Description

technical field [0001] The invention relates to the field of manufacturing equipment and methods for double-layer bricks such as paving bricks, in particular to a forming device and a forming process for double-layer bricks. Background technique [0002] There are various forms of bricks, such as paving bricks and wall bricks, and the manufacturing equipment and methods of bricks are relatively mature and common. For example, Chinese invention patent CN201110163868. Formwork, the lower formwork is provided with a mold for brick forming, the mold includes a mold bottom plate, and the brick forming machine also includes a vibrating table for transmitting vibration force to the mold bottom plate, and the vibration The table includes a vibration force output end, and an opening and closing mechanism is provided between the mold bottom plate and the vibration force output end of the vibration table to make the two drive and cooperate to vibrate together and separate from each oth...

Problems solved by technology

However, the production and processing process of this invention patent is still in a discontinuous form, and it is impossible to form a continuous operation form in the form of an assembly line, and it is difficult to significantly improve the efficiency. Moreover, this equipment and its processing method are not suitable for the production and processing of double-layer bricks, especially because the materials have different properties. double brick structure

However, double-layer bricks such as paving bricks with a lining layer and a bottom material layer are generally made by hand in the market, and the production and processing efficiency is low and the cost is high. Moreover, in the actual use of this product, the lining layer and the bottom material layer are prone to separation. In the case of delamination, the strength of the product cannot meet the requirements for use, and the quality of the product is uneven. Therefore, new practical equipment and process forms for the production and processing of double-layer bricks need to be proposed urgently
