Slab sanding technique for plywood

Abstract

The invention discloses a slab sanding technique for plywood. The slab sanding technique comprises a sand belt select-exchange system and a slab sanding system. The sand belt select-exchange system and the slab sanding system are matched mutually to provide high-quality and matched sand belts for slab sanding of different plywood, a foundation is laid for high-quality slab sanding, and adaption universality is guaranteed. When charged into a sanding machine, the slabs are taken and put gently, bumping of the slabs is avoided, and the high quality of slab sanding of the plywood is guaranteed. A sand belt quality detection module is connected with a dull-polish performance testing module and a sand belt comparing module. After the sand belts are purchased, dull-polish performance testing is conducted on selected coarse sand belts, the situation that the dull-polish surfaces of the sand belts are matched with the ply wood, the appropriate coarse sand belts are selected to be compared and tested, and the coarse sand belts with the good sanding effects are purchased and customized on a large scale. High precision of slab sanding of the plywood is guaranteed, the better and safer sand belts are provided for the slabs, and sanding and polishing effects of the slabs are better.

Description

technical field [0001] The invention relates to a plywood process, in particular to a plywood slab sanding process, and belongs to the technical field of plywood slab sanding applications. Background technique [0002] With the rapid development of people's living standards, plywood is used very frequently in people's lives. Plywood is a three-layer or multi-layer board made of wood segments that are peeled into veneers or sliced ​​into thin wood, and then glued with adhesives. It is usually made of odd-numbered layers of veneers, and the fiber directions of adjacent layers of veneers are glued perpendicular to each other. Plywood is one of the commonly used materials for furniture, and it is one of the three major boards of wood-based panels. It can also be used for aircraft, ships, trains, automobiles, buildings and packaging boxes. A group of veneers are usually assembled and glued together according to the direction of the wood grain of adjacent layers perpendicular to ...

AI Technical Summary

Problems solved by technology

[0003] The existing sanding process of plywood slabs has confusion in the selection of abrasive belts, poor quality of abrasive belts, incompatibility of abrasive belts with different slabs, insufficient adaptation, poor adaptation accuracy, and poor quality of slab sanding , the surface of the slab is not smooth and flat after sanding, and the disadvantages of low fitting accuracy
