Problems solved by technology

[0002] At present, the laying and splicing of laminated veneer lumber (LVL: Laminated Veneer Lumber) in China is still carried out by manual billet laying of plywood, which has low production efficiency, high labor costs and unstable product quality.
Artificial pavement is random, the joints are separated or overlapped, the distance between joints is uneven, the effect of lengthening and the quality of paving are poor, resulting in low quality and strength of LVL products; in addition, traditional The pavement method is discontinuous length pavement, which requires multiple trimmings, resulting in a lot of veneer loss and a large waste of raw materials

specific Embodiment approach 1

[0020] Specific implementation mode one: refer to Figure 1 to Figure 4 , The continuous pavement of the laminated veneer lumber in this embodiment is completed according to the following steps. One, the veneer with a thickness of 3mm, which has been graded and matched by moisture content, density and surface quality, is subjected to oblique grinding at both ends by an oblique mill (21), and the slope length of the oblique grinding is 30mm; The veneer passes through the glue brushing machine (22) to brush glue on the oblique grinding parts at both ends, then passes through the glue spreader (23) to apply glue on the upper surface, and is transported to the front part of the mobile paving head (12) by the belt conveyor (11) and waits; 3. The veneer enters the belt conveyor (1) of the mobile paving head (12) at station A and is transported forward to the baffle (4), and the belt conveyor (1) passes through the rotation at station O The reduction motor (7) rotates 15° clockwise,...

specific Embodiment approach 2

[0021] Specific embodiment two: the difference between this embodiment and specific embodiment one is that the veneer thickness is 2mm, and the slope length of the oblique mill is 20mm. After completing the paving of a veneer, the pavement belt conveyor (13) is backward The stepping distance is 100mm. Other specific implementations are the same as the first specific implementation.

specific Embodiment approach 3

[0022] Specific embodiment three: the difference between this embodiment and specific embodiment one is that the veneer enters the belt conveyor (1) of the mobile paving head (12) at station A and is transported forward to the baffle plate (4 ), the belt conveyer (1) rotates 60° clockwise through the rotating deceleration motor (7) at the station O, and at the same time the compression cylinder (3) is pressed down so that the compression cylinder (2) and the baffle (4) move along the guide rail (5) Move down to the veneer so that the veneer falls into the ladder formwork (8). Other specific implementations are the same as the first specific implementation.

Abstract

The invention provides a continuous forming system for a laminated veneer lumber (LVL), which is a novel equipment invention in the field of wood processing in China, can replace similar imported equipment to improve the processing and utilizing efficiency and quality of fast-grow forest woods. The system comprises a belt conveyer, a mobile forming head and a forming belt conveyer, and is mainly used for continuous lengthening and forming of each veneer of the laminated veneer lumber. The continuous forming system has the advantages of realizing continuous lengthening and forming to the veneer, overcomes the defect that the traditional process requires manual forming, improves the processing efficiency of forming, and reduces the manual cost of forming; in the forming process, the veneer can be accurately positioned and lengthened, and the joint of each veneer is regularly separated, so as to ensure that higher quality and strength of the laminated veneer lumber after forming to accord with the requirement of international laminated veneer lumber quality standard; and continuously lengthening and forming avoids material waste caused by multiple times of trimming of the laminated veneer lumber to improve the material utilization of the veneer.

Description

(1) Technical field [0001] The equipment relates to an automatic continuous paving equipment for veneer multilayer boards, in particular to a continuous paving system for laminated veneer lumber (LVL). (2) Technical background [0002] At present, the laying and splicing of laminated veneer lumber (LVL: Laminated Veneer Lumber) in China is still carried out by manual billet laying of plywood, which has low production efficiency, high labor cost and unstable product quality. Artificial pavement is random, the joints are separated or overlapped, the distance between joints is uneven, the effect of lengthening and the quality of paving are poor, resulting in low quality and strength of LVL products; in addition, traditional The pavement method is discontinuous length pavement, which requires multiple trimmings, resulting in a lot of veneer loss and a large waste of raw materials. (3) Contents of the invention [0003] In order to solve the current situation of manual stackin...
