Problems solved by technology

[0015] 1. In the production process of laminated veneer lumber, the specification length of the raw veneer is often different from the specification and length of the actually required veneer laminated lumber, and the length of the veneer needs to be extended. The two ends of the board are milled with slopes, and then the two milled veneers are glued together to lengthen, and then cut to the required length, there will be surplus material during the cutting process, if the surplus material is long, it can be lengthened again. If it is too short, it will become waste. This method not only wastes raw materials, but also requires long working hours;

[0046] Such as Figure 2-Figure 4 Shown: a production method of laminated veneer lumber, comprising the following steps:

[0047] (1) Preparation of the veneer: prepare the veneer 1 with the same length, mill the two ends into inclined planes, and set aside;

[0048] (2) Glue application and blank assembly: apply glue on the surface of each veneer by a glue spreader, and then use the blank assembly machine to assemble the blanks on the blank assembly platform. The blank assembly machine is set on the blank assembly platform A backer, the veneer 1 is placed against the mountain when placed,...

Abstract

The invention discloses a production method of laminated veneer lumber. The method comprises the following steps of: (1) preparing a single veneer; (2) coating and assembling; (3) intermittently prepressing; (4) interrupting an assembly plate; (5) thermally pressing; (6) trimming and sawing; (7) sanding; and (8) packaging and putting in a storehouse. The invention simplifies the original production process step, saves raw materials and equipment and reduces the power consumption. The production method can be adopted to save a lot of wood resources by avoiding longitudinally trimming both ends of a laminated veneer lumber blank, also strictly prevent single veneer seams of all layers from superposing, improve the quality of the laminated veneer lumber, save time and labor and improve the working efficiency by avoiding adjusting equipment because of the specification requirement in the production process.

Description

technical field [0001] The invention relates to a production method of wood-based panels in the wood industry, in particular to a production method of laminated veneer timber, which belongs to the technical field of wood processing. Background technique [0002] figure 1 It is a schematic diagram of the production process of traditional laminated veneer lumber. [0003] Such as figure 1 Shown: The production process of traditional laminated veneer lumber is: [0004] (1) Prepare the veneer: the production of veneer: After cooking and softening the log, place it on a rotary cutter to cut a veneer with a thickness of about 3mm. After the veneer is unscrewed, it will be cut into a veneer of a certain length by a shear , After the veneer is dried to a certain moisture content, the moisture content is generally controlled at about 6%, in order to prepare for the manufacture of laminated veneer lumber, or directly purchase veneer from the market to produce laminated veneer lumb...
