Rhombic roller type sieving machine

Abstract

The invention discloses a rhombic roller type sieving machine, which relates to an artificial board sieving machine. A motor cabinet A (11) of an upper speed reduction motor (10) is arranged on one side of the upper part of a frame (4); a crankshaft of the upper speed reduction motor (10) is connected with one end of a material dividing propeller (1) which is arranged in a box body; the upper part of the material dividing propeller (1) is provided with a material inlet; the upper part of a material guiding plate (13) corresponds to the lower part of the box body of the material dividing propeller (1), while the lower part is extended to a part above at least one rhombic roller (24) of a sieving device consisting of a plurality of groups of rhombic rollers (24); the two ends of each rhombic roller (24) are provided with a bearing respectively; and a plurality of groups of granular material sieving mechanisms consisting of at least three rhombic rollers (24) are arranged in parallel in the frame (4). The rhombic roller type sieving machine is arranged between two pieces of equipment for delivering shaving materials mixed with glue to separate micelles or other large materials from the shaving materials after the materials are sieved so as to effectively improve the surface quality and appearance of finished products of artificial boards.

Description

【Technical field】 [0001] The invention relates to a wood-based panel screening machine, in particular to a diamond-shaped roller-type sheet material screening machine. 【Background technique】 [0002] In the process of wood-based panel processing, it is necessary to use the scraps, also called fine particles, bagasse materials, scraps made of lignocellulosic materials, and glue them together under the action of heat and pressure after applying adhesives. Also known as particle board. It is mainly used in the furniture and construction industry and in the manufacture of train and car carriages. Particleboard is divided into three types according to product density: low density (0.25-0.45 g / cm3), medium density (0.55-0.70 g / cm3) and high density (0.75-1.3 g / cm3), usually 0.65-0.75 g Particleboard with a density of / cm3; according to the arrangement of the shavings in the slab, there are two types: directional type and random type. In addition, there are particle boards made...

Problems solved by technology

Based on the fact that particleboard is a thin board made of wood chips as the main raw material, and then infiltrated or sprayed with glue and additives, it is unavoidable that there are often micelles in the particleboard that has been mixed with glue. After wind paving, some rubber groups are distributed on the surface of the forming board "that is, black spots", which causes the board surface to be unsightly. To the follow-up flat weighing table for weighing and pressing the pressing material, there are defective products
