An environmentally friendly plywood pressing device

Abstract

The invention discloses an environment-friendly plywood laminating apparatus, comprising a base and lifting posts. A cross beam is arranged on the lifting posts; a spindle is arranged on the cross beam; a driving flange and a support sleeve are arranged on the spindle; push cylinders are arranged between the driving flange and a fixing disc; a pressing disc is arranged on the spindle; a first cylindrical spring is arranged on a telescopic shaft; a linkage is arranged on the driving flange and the support sleeve; a pressing ring is arranged on the linkage; pushing units are arranged between thepressing ring and the pressing disc. The driving flange and the support sleeve on the spindle are used such that push forces generated by the push cylinders in multiple positions are gathered to acton the driving flange, limiting action of the spindle allows the push pressures to be gathered into a force along the axis of the spindle, the pushing pressures are evenly distributed via the linkageso that each pushing unit generates equal pushing pressure, and plywood laminating effect is greatly improved.

Description

technical field [0001] The invention relates to the technical field of wood board pressing devices, in particular to an environment-friendly plywood pressing device. Background technique [0002] Plywood is a three-layer or multi-layer board-like material that is made of wood sections that are peeled into veneers or sliced ​​into thin wood, and then glued with adhesives. Usually, odd-numbered veneers are used, and adjacent layers of veneers are used. The fiber directions are glued perpendicular to each other. [0003] Plywood is one of the commonly used materials for furniture, and it is one of the three major boards of wood-based panels. It can also be used for aircraft, ships, trains, automobiles, buildings and packaging boxes. A group of veneers are usually assembled and glued together according to the direction of the wood grain of adjacent layers perpendicular to each other. Usually, the surface board and inner layer board are symmetrically arranged on both sides of th...

AI Technical Summary

Problems solved by technology

[0004] The plywood is inseparable from the pressing device in the manufacturing process. The effect of plywood pressing determines the quality of the finished product. If there are defects in the pressing process, it is easy to cause incomplete bonding of the plywood, causing problems such as warping and unevenness; the existing The pressing device is generally operated by a cold press, and the conventional cold press generally uses two push rods to push the pressing plate to achieve pressing. It forms a force distributed in a plane during the process of applying pressure. When pushing When the rod pressure is too large, it is easy to cause excessive force on the plywood around the push rod, and weak force on other parts, which will easily cause uneven pressure on the plywood and affect the quality of the finished product
