Description

Technical Field

[0001] The utility model relates to the technical field of plywood drying, in particular to a drying device for plywood. Background Art

[0002] After the peeling process, the veneer will be dried, mainly to reduce the moisture content of the veneer. If the moisture content of the veneer is too high, it will cause bubbling, degumming, deformation and surface cracks after hot pressing of the plywood, thereby affecting the gluing quality. From the perspective of production efficiency, if the moisture content of the veneer is high, it will cause bubbling, cracking and other problems during the production of plywood, which will not only affect the quality of the product, but also reduce the production efficiency. Through drying treatment, the moisture content of the veneer can be effectively reduced, thereby improving production efficiency and product quality.

[0003] The existing drying devices still have certain shortcomings when applied to the drying processing operation of film-faced plywood. First, the film-faced plywood needs to be transported by conveying mechanisms such as conveyor rollers or conveyor belts during the drying process. At this time, only one side of the board can receive a relatively good drying effect. The operation of drying one side and then turning it over to dry the other side will lead to low overall drying efficiency of the device. In addition, when the film-faced plywood is transported by simply conveyor rollers or conveyor belts, the board may slide or deviate during operation, affecting the drying progress of the entire production line.

[0004] The Chinese utility model patent currently announced as CN219486839U discloses a drying device for producing film-coated plywood, which relates to the technical field of drying devices, including a No. 1 conveying cabin and a No. 1 movable cabin, as well as a No. 2 conveying cabin and a No. 2 movable cabin. This drying device for producing film-coated plywood uses the No. 1 conveying cabin and the No. 1 movable cabin as well as the No. 2 conveying cabin and the No. 2 movable cabin together, so that during the drying process of the drying device for producing film-coated plywood, the film-coated plywood needs to pass through the inner sides of the No. 1 conveying cabin, the No. 1 movable cabin, the No. 2 conveying cabin and the No. 2 movable cabin. During the passage of the board, the upper board surface is dried between the No. 1 conveying cabin and the No. 1 movable cabin by the electric heating device and the hot air unit installed on the No. 1 movable cabin, and then the lower board surface is dried by the electric heating device and the hot air unit installed in the No. 2 conveying cabin when passing between the No. 2 conveying cabin and the No. 2 movable cabin.

[0005] In view of the above problems, the existing patents provide solutions, but during use, only a single piece of plywood can be moved and heated on the roller, and because the roller is not a flat surface, the plywood can be easily deformed by pressing too tightly up and down during heating, and it is not convenient for subsequent sorting and collection after heating.

[0006] For this reason, a drying device for plywood is proposed. Utility Model Content
