Problems solved by technology

[0002] The plywood and multi-layer boards produced in my country still have poor flatness, deformation, warping, and cracking are very serious, and can only be used as building templates and packaging boxes. Indeed, due to poor quality and poor flatness, they cannot be used for furniture, wooden doors, and decorations. The plywood horizontal veneer with vertical and horizontal structure is not suitable for processing; although the multilayer board with full longitudinal structure solves the problem of easy processing of multilayer board, the phenomenon of deformation and cracking is very serious

Embodiment Construction

[0024] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0025] The present invention proposes a kind of production method of multi-layer board, comprises the steps:

[0026] 1) Sorting the veneers by grade, screening the first-level veneer 1, the veneer 1 can be the first-class poplar veneer, poplar rotary-cut (multi-wood species) veneer;

[0027] 2) Dry the veneer after air-cooling to keep the moisture content of the veneer at 7%-14%;

[0028] 3) Set several rows of slits 2 along the length of the veneer. Each row of slits includes several slits arranged at intervals on the same straight line. The specifications of each slit are the same, and the interval between each slit is 26 is the same as the length of the slit, and there is a distance between two adjacent rows of slits. In every two...

Abstract

The invention provides a multilayer board, a producing method for the multilayer board and a lancing device for a veneer of the multilayer board. According to the anti-deformation multilayer board and the producing method, a lance is formed in the veneer; the structural relation of the lance can provide a deformation space for the veneer when the veneer is deformed, so that overall deformation of the veneer is prevented; at the same time, the lancing device for the veneer of the multilayer board can process the lance with an anti-deformation structure on the veneer quickly, and the overall deformation of the veneer is prevented. According to the provided multilayer board, the technical effects of being free from deformation, layering, bubbling and seaming and high in nail-holding power can be achieved.

Description

technical field [0001] The invention relates to the field of production of multilayer boards, in particular to a multilayer board, a production method of the multilayer board and a cutting device for a single board of the multilayer board. Background technique [0002] The plywood and multi-layer boards produced in my country still have poor flatness, deformation, warping, and cracking are very serious, and can only be used as building templates and packaging boxes. Indeed, due to poor quality and poor flatness, they cannot be used for furniture, wooden doors, and decorations. and the horizontal veneer of plywood with vertical and horizontal structure is not suitable for processing; although the multilayer board with full longitudinal structure solves the problem of easy processing of multilayer board, the phenomenon of deformation and cracking is very serious. Contents of the invention [0003] In order to solve the defects and deficiencies of the prior art, embodiments of...
