Production assembly line of self-thermal insulation concrete blocks

Abstract

A production assembly line of self-thermal insulation concrete blocks is composed of a material stirring device, a blank making device, a cutting device, a backward-skating-prevention drying device and a brick holding machine which are sequentially arranged on a rail and further comprises a conveying device which reciprocates along the rail and is used for conveying materials. Raw materials used for making the self-thermal insulation concrete blocks are stirred in the material stirring device and then are injected into the blank making device to be subject to foam forming so as to make green bricks, the green bricks are conveyed to the cutting device through the conveying device to be cut, and the cut green bricks pass through the backward-skating-prevention drying device and then are moved out of the assembly line through the brick holding machine. According to the production assembly line of the self-thermal insulation concrete blocks, in the process of making the self-thermal insulation concrete blocks, effects of being rapid to demould, stable in cutting, free of backward skating of the conveying device during drying, safe in brick holding transferring and the like are achieved, and the production efficiency is greatly improved while the product quality is ensured.

Description

technical field [0001] The invention relates to the field of production equipment for self-insulating blocks for buildings, in particular to a production line for self-insulating blocks. Background technique [0002] The production process of self-insulating blocks includes several steps such as upper mold, injection of materials, vibration and exhaust, shaping, demoulding and cutting. Among them, demoulding is one of the key technologies that directly affects the final yield of self-insulating blocks. After the self-insulating block body is foamed and formed, the body is relatively moist and soft, and the strength is not enough. If the demoulding is not done properly, the body will crack or even crack. In the prior art, the self-insulating block assembly line is used to produce bricks.

[0002] The production process of self-insulating blocks includes several steps such as upper mold, injection of materials, vibration and exhaust, shaping, demoulding and cutting. Among them, demoulding is one of the key technologies that directly affects the final yield of self-insulating blocks. After the self-insulating block body is foamed and formed, the body is relatively moist and soft, and the strength is not enough. If the demoulding is not done properly, the body will crack or even crack. In the prior art, the self-insulating block assembly line is used to produce bricks. There are two main ways to open the mold. One is to use a crane to lift the side plate of the mold as a whole. Since the mold is usually made of metal with high hardness and weight, it is very difficult to use a crane to lift vertically when demoulding. Inconvenient, the other is to remove the connecting parts between the side plates around the mold first, and then remove the side plates from around, because the self-insulating blocks belong to foam bricks, and the bricks are easy to crack in a wet state. The way of disassembling the mold is easy to cause the deformation of the adobe and reduce the utilization rate of the adobe. At present, most of the adobe molds on the market are made of metal materials and are heavy. In actual production, it is difficult to open the adobe mold, which affects the overall production. efficiency

[0003] Another problem that is not easy to solve in the traditional mold is that the self-insulating block material is liquid before foaming, and when it is poured into the mold where the side plate and the supporting plate are separated, there will inevitably be a problem of liquid leakage. The traditional The solution is to install a sealing strip on the contact surface between the side plate and the supporting surface, but the face-to-face sealing method is often not tightly sealed, which cannot solve this problem well

[0004] The demoulding process is to release the self-insulating block body that has been foamed and formed in the mold from the foaming mold. The demoulding method in the existing technology is to remove the baffles around the blanking mold. The formed self-insulating block body has a large water content and a relatively soft texture. The demoulding method of removing the mold-making baffle from the surroundings is very easy to cause fragmentation of the corners of the body and overall cracking of the body, and the damaged body When the body is in use, it is necessary to cut off the damaged part first, and then cut the remaining part, which greatly wastes the utilization rate of the body, so the design and structure of the demoulding method of dismantling around the outside is not reasonable enough, resulting in damage to the brick during demoulding body, the brick tray is difficult to reset, and at the same time reduces the overall production efficiency of the self-insulating block assembly line, and the brick-making quality is poor and the brick-making loss increases

[0005] Since most of the existing self-insulating block molds are made of metal, the quality is relatively large and heavy, and it is easy to clamp loosely and cause slippage during demoulding. The method of simply reinforcing the outside of the clamping claws is not very good. to solve this problem

[0006] When the transport device is moving along the track on the assembly line, in order to prevent the transport device from slipping due to inertia, the usual method is to set a clip on the pulley or track of the transport device, but the structure is usually complicated and the function is lacking. After the position is fixed, it cannot be pushed forward sequentially, and the positioning function between the transportation devices cannot be realized. Therefore, there is an urgent need for a method that can realize rapid demoulding, stable cutting, and non-slipping of the transportation device during drying in the process of preparing self-insulating blocks. Safe brick transfer and other effects, while ensuring product quality and greatly improving production efficiency, the self-insulating block production line
