Description

Sheet forming device

technical field

The invention relates to the technical field of plate forming, in particular to a plate forming device.

Background technique

At present, in the existing sheet forming technology, most of them use large-scale equipment to apply pressure to form, especially in the single-layer sheet forming process, the way of applying pressure to form is even more. However, with the development of society, the needs of life are becoming more and more diverse, and so is the panel field. In order to meet different needs, panel products with various functions have been developed, many of which have a double-layer composite structure or even a multi-layer composite structure. , that is, the plate is made of two or more raw materials, which will cause multiple pressures, and one equipment cannot perform multiple processes at the same time, and the production efficiency is low; at the same time, due to the poor fluidity of the plate raw materials, if If the cloth is uneven, it is easy to cause the quality of the board to fail to meet the requirements.

In order to solve the above technical problems, Chinese patent document CN102888943A discloses a preparation method of lightweight composite wallboard. The forming process is to place the forming mold on the assembly line conveying platform, and set the bottom layer in sequence along the assembly line above the assembly line conveying platform. Light aggregate concrete feeding system, bottom layer light aggregate concrete feeding system, reinforced mesh laying system, upper layer light aggregate concrete feeding system, upper layer light aggregate concrete rolling system, surface layer mortar feeding system, glass Mesh cloth laying system, surface mortar rolling system, and plastic film laying system, when the forming mold moves along the line, the bottom cement fiber panel, laying and rolling the bottom light layer are completed in the cavity of the forming mold in sequence. Aggregate concrete layer, placing reinforced mesh, paving and rolling upper lightweight aggregate concrete layer, laying and feeding surface mortar layer, laying glass mesh cloth, rolling surface mortar layer, laying plastic film and other wallboard forming A series of operations, and finally the mold is removed, and the lightweight composite wallboard is processed.

When the above-mentioned molding equipment is preparing lightweight composite wallboards, continuous operation is realized through assembly line settings, and a layer-by-layer rolling system is installed after the feeding system in turn to realize multi-process continuous pressure, so that the boards are compacted layer by layer.

But still there is following problem in above-mentioned technical scheme:

First, the rolling device of the forming equipment is realized by the rollers arranged above the conveying system. Since the rollers are not driven by power, they can only be passively driven by the concrete material on the formwork to realize the rolling process. On the one hand, it will increase the resistance of the pipeline conveying platform; on the other hand, when the concrete material just touches the roller, the material will be pushed back to the rear of the mold by the roller, which will make the front and rear materials of the board uneven, which will also affect the strength of the board , reducing product quality.

Second, due to the fixed position of the rolling system, it can only be applied to the production of products of one thickness, and cannot meet the needs of customers for products of various thicknesses.

Thirdly, the feeding system in the molding equipment includes a discharge hopper and a screw extruder arranged on the lower side of the discharge hopper. Since the concrete material is prone to subsidence, the material in the lower layer of the discharge hopper is denser than the material in the upper layer, so after feeding The concrete material extruded by the system is not uniform, that is, the feeding system preferentially extrudes the settled concrete material, so that the concrete material in the front and rear parts of the slab is not ideally mixed evenly, resulting in different strengths of each part of the slab , the quality is reduced.

Therefore, aiming at the above deficiencies, the present invention provides a plate forming device.
