Combined drying device suitable for industrial batch production of formaldehyde-free plywood

Abstract

The invention relates to the technical field of plywood production and processing equipment, and particularly relates to a combined drying device suitable for industrial batch production of formaldehyde-free plywood. The combined drying device comprises a machine body and a base, wherein the machine body is fixedly arranged on the base, universal wheels are symmetrically and fixedly arranged on the base, a rotating column is rotationally arranged in the machine body, a stepping motor used for driving the rotating column is arranged on the machine body, a sliding groove is formed in the circumferential direction of the rotating column, clamping plates are symmetrically arranged in the sliding groove in a sliding mode in the longitudinal direction, and the sliding groove is further providedwith an electric telescopic rod used for driving the clamping plates. According to the combined drying device, the mode of autorotation in the drying process of the plywood is adopted, so that the drying effect of the plywood is more uniform, and the phenomenon of scorching is avoided; and meanwhile, a drying mechanism is arranged, so that the phenomenon of drying dead angles of the drying work ofthe plywood is avoided.

Description

technical field [0001] The invention relates to the technical field of plywood production and processing equipment, more specifically, a combined drying device suitable for industrial batch production of formaldehyde-free plywood. Background technique [0002] Plywood is a three-layer or multi-layer board-like material that is made of wood sections that are peeled into veneers or sliced ​​into thin wood, and then glued with adhesives. Usually, odd-numbered veneers are used, and adjacent layers of veneers are used. The fiber directions 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. [0003] In existing plywood drying devices, the plywood is often fixedly installed in a drying box for drying, so that the drying effects of different surfaces of the plywood are different, a...

AI Technical Summary

Problems solved by technology

[0003] The existing plywood drying device is usually fixedly installed in the drying box for drying, so that the drying effects of different surfaces of the plywood are different, and even one side of the plywood is scorched, resulting in certain economic losses.
