Description

Technical Field

[0001] The utility model relates to the technical field of pressing machines, in particular to a clamping type positioning mechanism of a plywood pressing machine. Background Art

[0002] Plywood is a three-layer or multi-layer plate material made by peeling wood segments into veneers or planing wood into veneers, and then gluing them with adhesives. It usually uses an odd number of veneers, and glues the fibers of adjacent veneers perpendicular to each other. Plywood is one of the commonly used materials for furniture and one of the three major wood-based panels. It can also be used as a material for airplanes, ships, trains, cars, buildings, and packaging boxes. A group of veneers are usually glued together in a perpendicular direction to the grain of adjacent layers. 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 and pressed under heating or non-heating conditions. The number of layers is generally odd, and a few have even numbers. The physical and mechanical properties in the longitudinal and transverse directions are slightly different. Commonly used 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. The glue roller is a machine that applies glue to the wood board.

[0003] However, in the prior art, in the production process of plywood, pressing is a key process, which determines the flatness and stability of the plywood. However, traditional pressing machines mostly use a fixed positioning method when positioning plywood. This method cannot adapt to plywood of different sizes, and the positioning accuracy is not high, resulting in poor pressing effect. Therefore, the development of a new type of clamping positioning mechanism is of great significance to improving the production efficiency and product quality of plywood pressing machines.
