Slab paving device and paving system

Abstract

The invention provides a slab paving device for paving upper surface layers or lower surface layers to form slabs. The slab paving device comprises a paving box, a paving bin arranged at the upper part of the paving box and used for providing paving materials to the paving box, an airflow generating device arranged on one side of the paving box and used for generating air currents in a paving direction or an opposite direction in the paving box to sort the paving materials, and a classification paving module for classification pavement of the paving materials sorted by the airflow generating device. The invention further provides a slab paving system comprising the slab paving device.

Description

technical field [0001] The invention belongs to the field of slab manufacturing, in particular to a slab paving device and a paving system. 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 li...

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.
