Description

Technical Field

[0001] The invention relates to the technical field of plywood production and manufacturing, and in particular to a full-automatic hot pressing device for plywood production. Background Art

[0002] Plywood is a three-layer or multi-layer board material made by peeling wood segments into veneers or planing wood blocks into veneers, and then gluing them together with adhesive. It is usually made with an odd number of veneers, with the fibers of adjacent layers of veneers glued perpendicular to each other.

[0003] Plywood is one of the commonly used materials for furniture and one of the three major artificial boards. It can also be used as a material for airplanes, ships, trains, cars, buildings and packaging boxes. A group of veneers are usually assembled and glued together in the direction of the wood grain of adjacent layers perpendicular to each other. Usually, the surface board and the inner layer are symmetrically arranged on both sides of the center layer or the core. The veneers coated with glue are staggered in the direction of the wood grain to form a slab, which is pressed under heating or non-heating conditions. The number of layers is generally an odd number, and a few have even numbers. The physical and mechanical properties in the longitudinal and transverse directions are slightly different. Common types of plywood include three-ply board and five-ply board. Plywood can improve the utilization rate of wood and is a major way to save wood.

[0004] In the plywood production equipment, the hot pressing device is one of the most important equipment. At present, there are roughly three types of loading methods for hot pressing devices: the first is full manual loading and unloading of boards; the second is manual loading of boards to the board loading machine, manually pushing the hot-pressed slabs in the hot press to the receiving rack, and then feeding them from the board loading machine into the hot press, and manually stacking the boards at the receiving rack; the third is manual loading of boards to the board loading machine, automatically sending the hot-pressed slabs in the hot press to the receiving rack while leaving the blanks on the board loading machine in the hot press, and then stacking them. The above three types of loading and unloading of slabs have not achieved fully automatic operation, and not only increase the labor intensity of operators, but also reduce the production efficiency of plywood, which brings great inconvenience to the production of plywood. Summary of the invention

[0005] In order to solve the problems existing in the prior art, the purpose of the present invention is to provide a fully automatic plywood production hot pressing device which has a reasonable design, simple structure and convenient operation, and can realize full-automatic operation in the entire process of slab feeding, hot pressing and discharging, which not only reduces the labor intensity of operators, but also improves the production efficiency of plywood, thus bringing great convenience to the production of plywood.
