Production method of reinforced fiber slab body

Abstract

The invention relates to a production method of a reinforced fiber slab body. The method uses the following mechanisms and devices comprising a plate making machine, a slab receiving conveyor belt, atransition plate, a transition conveyor belt, an inlet transition plate, an extrusion device, an outlet transition plate, and a slab output belt. The production method comprises the steps that slabs with the moisture content of 30%-32% are produced by the plate making machine; the slabs are output to the slab receiving conveyor belt by the plate making machine; after passing the transition plate,the slabs are transferred to the transition conveyor belt; after passing the inlet transition plate, the slabs are moved into the extrusion device; and the slabs are transported to the outlet transition plate and the slab output belt by the extrusion device. The production method of the reinforced fiber slab body can reduce human uncontrollable factors, thus uniform and controllable thickness of slab bodies is achieved, the flatness meets requirements, the plate surface quality is more flat and smooth, high-quality slabs can be processed, great convenience is brought to thickness and flatnesscontrol of the subsequent process, the thickness processing is even no longer required for a fibreboard for general use, and the production efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of production of reinforced fiberboard blanks, in particular to a production method of reinforced fiberboard blanks. Background technique [0002] At present, in the production process of fiber-reinforced calcium silicate board and fiber-reinforced cement board, the thickness deviation has always been difficult to control. Taking the conventional board with a thickness of 6-10mm as an example, according to the national standard thickness deviation of JCT564-2018 fiber reinforced calcium silicate board industry is ±0.4mm, but the actual production thickness will deviate to ±1.0mm or more, which greatly exceeds the standard allowable deviation. In order to adjust the thickness, it is generally only through manual or online automatic thickness monitoring, and the value is fed back to the plate making operator, and then the thickness can be adjusted by manually controlling the running speed of the felt or adjust...

Problems solved by technology

However, due to irregular changes in various production conditions and factors (such as changes in return material concentration, pulp concentration changes, ingredients weighing errors and human factors, etc.) during production, the thickness and flatness cannot be stabilized at a standard value. Within the range, there is always a large deviation from the standard value. Even if the press is used for overall pressurization and flattening, it cannot guarantee that all thicknesses and flatness dimensions are uniform. Less, that is, deviate from the negative value

As a result, in the post-processing process, in order to control the thickness and flatness within the standard deviation range, it is necessary to remove the excess thickness through equipment and materials, which requires more production equipment and consumes more materials, such as increasing sanding. The number of machines and the consumption of sandpaper required for sanding the surface of the board also consume a lot of electricity. The production cost is high and the efficiency is low. It not only wastes a lot of financial resources, material resources and manpower, but also causes large environmental pollution on the production site, which is not conducive to modern enterprises.
