Multi-layer board hot press molding equipment

Abstract

The invention provides multi-layer board hot press forming equipment. The multi-layer board hot press forming equipment comprises a base, a mounting frame, a clamping and fixing mechanism and a rolling press fit mechanism. The invention provides the multi-layer board hot-press forming equipment, and can solve the following problems, existing in the board hot-press forming process, that a, a fiber board can be formed into a board with certain mechanical strength and water resistance through hot pressing of a plurality of board blanks, the application range of the plate is wide, according to a traditional hot-press forming device in the hot-press forming process, adjusting and aligning can nor be achieved during press fit of a plate blank, deviation is easy to occur, hot press forming is not achieved at the edge of a formed fiber plate, and the edge of the plate needs to be cut to be put into the market; and b, the existing hot-pressing device heats a single face of the plate blank, so that the hot-pressing effect is poor, the quality problem of a produced fiber plate is serious, and when the plate blank is pressurized in the hot-pressing process, the plate is pressurized unevenly, so that the plate is stressed unevenly in the hot-pressing process, and the quality of the formed fiber plate is different.

Description

technical field [0001] The invention relates to the technical field of plate hot-press processing, in particular to a multi-layer board hot-press forming equipment. Background technique [0002] Hot pressing is a process of heating and pressing the paved slab to make a fiber board with certain mechanical strength and water resistance. Whether it is hard board or semi-rigid board produced by wet method, or hard board or medium density board produced by dry method, it must be hot-pressed to become a board. When producing hard board by wet method, generally no adhesive is added. The bonding between fibers depends on the glue action between moisture and the intercellular layer material of wood cells and the filler between the thin fibers that make up the cell wall. The intercellular layer material and the filling between the thin fibers are multi-component polymer materials composed of lignin and hemicellulose. During hot pressing, the fibers are in close contact, and the inte...

AI Technical Summary

Problems solved by technology

[0003]Currently, the following problems exist in the hot-press forming process of boards: a. Fiber boards can be hot-pressed with multiple slabs to form boards with certain mechanical strength and water resistance , which has a wide range of uses. During the hot-press forming process, the traditional hot-press forming device fails to adjust the alignment when the slabs are pressed together, and is prone to misalignment, which leads to the failure of hot-press forming at the edge of the formed fiber sheet. The edge can only be put into the market after cutting; b. The existing hot-pressing device heats the slab on one side, which makes the hot-pressing effect poor, resulting in serious quality problems of the produced fiberboard, and adding heat to the slab during the hot-pressing process. When pressing, there is uneven pressure on the sheet, which leads to uneven force on the sheet during hot pressing, and the quality of the formed fiber sheet is not uniform.
