Embodiment 1
[0018] A manufacturing process of notched glulam, the process comprises the following steps:
[0019] (1) Logs are harvested from the forest farm, and the logs are broken into boards by machines;
[0020] (2) putting the plate obtained in step (1) into a drying kiln for drying, the drying temperature is maintained at 45-80°C, and the water content of the plate is dried to 6-12%;
[0021] (3) Cool the dried plate to 35°C and leave the kiln;
[0022] (4) Make the plate after leaving the kiln into a standard plate according to needs;
[0023] (5) cut off scabs and cracks from the specification plate made by step (4) using a chop saw;
[0024] (6) Polishing the standard plate processed in step (5) using four-side polishing;
[0025] (7) Use a comb machine and a finger jointer to finger-join the specification plate after step (6) polishing into 6 meters;
[0026] (8) The finger-joint plate gained in step (7) is polished using four-sided polishing;
[0027] (9) Use a jigsaw and...

Abstract
The invention discloses a manufacturing technology of notched glued laminated timber. The manufacturing technology comprises the following steps that a log is broken into plates to be dried through adrying kiln to reach the required moisture; the dried plates are manufactured into required specification plates; scars and cracks are cut off through a cutting saw; four-face dressing is conducted; then the specification plates are connected into the required length through a comb machine and a finger joint machine; then the finger joint plates are dressed through a four-face planer; and then thefinger joint plates are glued together according to the required thickness through a plate splicing machine and imported environment-friendly glue to be manufactured into the notched glued laminatedtimber. The manufacturing technology has the advantages that the notched glued laminated timber is manufactured through matching of the imported environment-friendly glue and the plate splicing machine, environmental protection and hygiene are achieved, the bonding effect is good, the glued laminated timber is processed through the technology that finger joint and splicing are combined, thus the glued laminated timber has the advantages of being high in strength and not liable to crack, an operator can manufacture the notched glued laminated timber of different sizes and shapes according to the specific using needs, the timber can be effectively saved, the cost is saved, and the environment is protected.
Description
technical field [0001] The invention relates to the field of wood production, in particular to a production process of notched glulam. Background technique [0002] Wood is a common material in people's daily life, which brings a lot of convenience to people's life, but excessive use of wood will also cause forest damage and bring great challenges to the ecological environment.
