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

Embodiment 1

[0025] Embodiment 1: An environment-friendly plywood pressing device, comprising a base 1 and two lifting columns 11 symmetrically arranged on the base 1, a beam 12 capable of moving up and down is arranged between the two lifting columns 11, The crossbeam 12 moves up and down through the lead screw arranged in the lifting column 11, the two ends of the crossbeam 12 are threadedly assembled with the lead screw respectively, and the top of the lifting column 11 is fixedly provided with a lifting motor for driving the lead screw to rotate. 13, wherein the lifting motor 13 is a stepping motor or a servo motor with a self-locking function, the middle part of the beam 12 is fixed with a main shaft 2 through a fixed plate 23, and the main shaft 2 is nested with a driving flange from top to bottom 21 and a support sleeve 22, four push cylinders 7 evenly distributed along the circumferential direction are arranged between the driving flange 21 and the fixed plate 23, and the pressure p...

Embodiment 2

[0032] Embodiment 2: On the basis of Embodiment 1, the elastic member (disc spring 64) of the pushing unit 6 can also be replaced by a second cylindrical spring. In this embodiment, the compression displacement of the pushing unit 6 The amount greater than the compression displacement of the first cylindrical spring 42 means that under the same force, the compression amount of the second cylindrical spring is greater than the compression amount of the first cylindrical spring 42, that is, when the driving flange 21 presses down and applies force. During the process, both the first cylindrical spring 42 and the second cylindrical spring are deformed at first, and then the first cylindrical spring 42 remains undeformed, and the second cylindrical spring continues to deform.

[0033] In other embodiments, the number of the pushing cylinder 7 , the link mechanism 5 and the pushing unit 6 can be further increased according to the size of the actually processed plywood, so as to achi...

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...
