Problems solved by technology

The above is the basic method of traditional craftsmanship. Since the ends of the wooden strips are not tightly connected, there are gaps, gaps, and even holes. Therefore, the longitudinal static bending strength of the finished product is low, which reduces the strength of the board and has a negative impact on subsequent use. Cannot be used as structural material

Embodiment Construction

[0008] The present invention will be further described according to specific embodiments below:

[0009] After the poplar core is made into slats according to the requirements, the slats are dried in a conventional steam drying kiln, and the moisture content of the slats is controlled at 10-12% after drying; the dried slats are processed on both sides by four-sided planing. Ensure that the thickness of the slats is consistent; make the tenon, after the length is glued, the side is planed to ensure that the side of the core strip is flat, and the parameters of the tenon: the tooth length is 12-13mm, the width of the tooth top is 0.9mm, and the width of the tooth bottom 0.68mm, tooth pitch is 4mm, fitting degree is 0.1~0.3 mm; the slats are matched and glued, and the gluing is manual gluing on the side of the slats; after the slats are glued, they are sent to the jigsaw machine at a temperature of 100 At ~125°C, the slabs are assembled into slabs, and the assembled slabs are nat...

Abstract

The invention discloses a production process for the finger connection of laminated wood board, which is characterized by comprising the following procedures: after manufacturing board strips, drying; determining the thickness and processing both faces; manufacturing tenons and slicing the side faces after jointing with glue; matching the board strips and coating the glue; carrying out split jointing on the board strips to make a board blank and cooling naturally; performing primary thick sanding; after pasting a transverse single board, performing pre-pressing, hot-pressing and natural-cooling; performing secondary thick sanding; and after pasting a surface board on the board blank, performing secondary pre-pressing, cutting edges after hot-pressing, and processing by fine sanding to obtain a finished product. The production process adopts the longitudinal glued joining of wood, enhances the longitudinal static bending strength of the finished product of a board material greatly and increases the strength of the board material, and the strength of the board material can reach more than 70% of the strength of raw materials.

Description

technical field [0001] The invention relates to a production process of blockboard. Background technique [0002] In the production of conventional blockboards, the wood strips are glued horizontally by hand or with a core strip gluing machine. The specific method is to apply glue on one side of the wood core strips, and then meet the size requirements to form the glued core strips into a slab. column form. There is no glue at the ends of the wooden strips, and the joints at the ends of adjacent wooden strips are staggered by more than 50mm, so as not to affect the strength, and then enter the follow-up process after hot pressing. The above is the basic method of the traditional craft. Since the ends of the wooden strips are not tightly connected, there are gaps, gaps, and even holes. Therefore, the longitudinal static bending strength of the finished product is low, which reduces the strength of the board and has a negative impact on subsequent use. Cannot be used as stru...
