Double-sided processing wood sanding device

Abstract

The invention relates to the technical field of wood processing, in particular to a double-sided processing wood sanding device which comprises a front surface sanding machine, a back surface sanding machine, an overturning device, a conveying device and a supporting device. The overturning device comprises an overturning motor, a main shaft and four overturning assemblies, and the four overturning assemblies are evenly distributed on the main shaft in a surrounding mode. The overturning assembly comprises a plurality of supporting pieces evenly distributed in the axial direction of the main shaft, and gaps capable of containing wood are formed in the supporting pieces. The production line comprises the front surface sanding machine, the back surface sanding machine, the overturning device and the conveying device. The front surface sanding machine is used for sanding the front surface of wood, the conveying device is used for conveying the wood to the overturning device to be overturned, and the overturned wood is conveyed to the reverse surface sanding machine through the conveying device to be subjected to reverse surface sanding treatment. Front and reverse surface sanding, conveying and overturning are synchronously carried out, so that the work efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of wood processing, in particular to a wood sanding device for double-sided processing. Background technique [0002] Before the production of wood flooring, it is necessary to rough process and further refine the wood panels of different specifications and types. The wood used in the wooden floor includes plywood boards, and more of them are boards that have been roughly processed and sawn from the original wood. These sawn boards, the two wide surfaces and the narrow sides are very rough, with many large chips and unevenness. In order to obtain smooth and delicate wooden floor raw materials, it is necessary to perform rough sanding, fine sanding, or even fine sanding on the log boards; during the sanding process, the surface of each wood board must be sanded by a sanding machine. In particular, the two wide surfaces of the wooden board need to be sanded sequentially. After finishing one surface of the bo...

Problems solved by technology

However, the sanding machine of the above-mentioned patent can only process one plate in one working process, and the sanding machine of this patent needs to transport the plate to the sanding mechanism for frontal sanding, and then lifts the plate to the automatic turning mechanism. Pick up the board and turn it over, then drop it to the conveyor belt and transport it to the sanding mechanism for reverse sanding. The whole process is cumbersome, and it takes a long time to process a board and the efficiency is low.
