Plate blank paving method

Abstract

The invention provides a plate blank paving method. The plate blank paving method comprises the following steps of paving a lower surface layer of a plate blank; paving a core layer of the plate blank; and paving an upper surface layer of the plate blank, wherein the step of paving at least one of the lower surface layer of the plate blank and the upper surface layer of the plate blank comprises the following steps of grading paving materials through gas flow; performing secondary grading on the paving materials subjected to gas-flow grading through a grading paving assembly; and paving the paving materials subjected to secondary grading to form a surface layer of the plate blank.

Description

technical field [0001] The invention belongs to the field of slab manufacturing, in particular to a slab paving method. Background technique [0002] In the existing panel production methods, slab paving and forming is one of the important processes of panel production. The quality of paving is directly related to the weight, output and cost of finished panels, while the diversification and low standardization of raw materials are also Higher requirements are put forward for the slab paving device and paving system. [0003] At present, air-flow paving machines are widely used in the production of particleboard. The principle of the air-flow paving machine is to use the action of the air flow to sort and pave the sizing shavings. The loose shavings fall into the airflow field formed by the air grille, and the shavings are instantly accelerated and sorted, and the thicker and larger shavings fall to the place closer to the air grid, while the fine and light shavings fall to...

Problems solved by technology

In order to prevent large pieces of shavings (such as large but light weight shavings) from being paved on the surface of the slab, traditional air-flow paving machines generally include vibrating screens, such as figure 1 As shown, it shows that the traditional air-flow paving machine 100 includes a plurality of vibrating screens 11, thus causing the structure of the traditional air-flow paving machine to be complex

Moreover, during the sorting process, large pieces of shavings are easy to hang on the vibrating screen, which will cause the sizing shavings to be blocked at the vibrating screen, requiring shutdown and manual cleaning of the vibrating screen, which seriously affects the normal production process and reduces work efficiency.
