A kind of production method of reinforced fiber board body

Abstract

The invention relates to a method for producing a reinforced fiberboard blank. In the method, the following mechanism devices are used, including a board making machine, a blank conveyor belt, a transition plate, a transition conveyor belt, an entrance transition plate, an extrusion device, an exit transition plate, a board Slab output belt, the steps are: use the slab machine to produce slabs with a moisture content of 30% to 32%; the slab machine outputs the slabs to the slab conveyor belt; the slabs are transferred to the transition conveyor belt after passing through the transition plate ; The slab moves to the extrusion device after passing through the entrance transition plate; the slab is transported by the extrusion device to the exit transition plate and the slab output belt. The invention can reduce artificial uncontrollable factors, thereby realizing the uniform controllable thickness of the green body and meeting the requirements of the flatness, smoother and smoother board surface quality, and being able to process high-quality slabs, and controlling the thickness and flatness for subsequent processes Bringing great convenience, the general-purpose fiberboard does not even need to be processed in thickness, 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.
